The subcutaneous (SC) form of vedolizumab is effective, generally safe, and well tolerated as maintenance treatment following intravenous vedolizumab induction in patients with moderately to severely active ulcerative colitis, results from a phase 3, double-blind trial demonstrated.

“The route of drug administration can be an important determinant of a patient’s treatment experience, particularly for chronic diseases such as UC [ulcerative colitis],” investigators led by William J. Sandborn, MD, of the division of gastroenterology and hepatology at the University of California, San Diego, wrote in a study published online in Gastroenterology (doi: 10/1053/j.gastro.2019.08.027). “Intravenous administration of a biologic treatment requires the patient to set time aside and travel to a treatment center for an infusion. In addition, the greater use of a health care facility increases the direct costs of care. Some studies show that even with the option of self-injection some patients may still prefer an IV route of administration for the reassurance provided by the opportunity for interacting with a health care professional or because they are averse to self-injection. The availability of both an SC and IV injection of vedolizumab will enable patients to choose the route of administration for maintenance treatment.”

Between Dec. 18, 2015, and Aug. 21, 2018, Dr. Sandborn and colleagues at 141 sites in 29 countries enrolled 353 patients with moderate to severely active UC to receive IV vedolizumab 300 mg at weeks 0 and 2. At week 6, 216 patients who demonstrated clinical response were randomly assigned to maintenance treatment: 106 to SC vedolizumab 108 mg every 2 weeks, 54 to IV vedolizumab 300 mg every 8 weeks, and 56 to placebo. The study’s primary endpoint was clinical remission at week 52, which was defined as a total Mayo score of 2 or lower and no subscore greater than 1.

The mean age of patients was 40 years and 60% were male, and they had UC for a mean of 8 years. At week 52, the researchers found that clinical remission was achieved by 46.2% of patients in the SC vedolizumab group, compared with 42.6% of patients in the IV vedolizumab group and 14.3% of patients in the placebo group. In addition, patients in the SC vedolizumab group experienced significantly greater rates of endoscopic improvement and durable clinical response compared with those in the placebo group (P less than .001).

In terms of safety, injection-site reactions were noted by 10.4% of patients in the SC vedolizumab group (mostly rash, swelling, erythema, and pruritus), compared with 1.9% of patients in the IV vedolizumab group and in no patients in the placebo group. “No serious cases were reported for the AEs of special interest: hypersensitivity (including injection site reactions or infusion-related AEs), malignancies, and liver injury,” the researchers wrote. “There were no cases of PML [progressive multifocal leukoencephalopathy] and no deaths.” They acknowledged that the study’s sample size was smaller than the previous GEMINI pivotal trial for vedolizumab IV in ulcerative colitis (N Engl J Med 2013;369:699-710). “This limitation may have contributed to the findings of numerically greater but not statistically significant differences between treatment arms for some secondary endpoints such as durable clinical remission and corticosteroid-free clinical remission,” they wrote.

BARCELONA – Upfront use of a dual combination of vildagliptin (Galvus) and metformin was associated with better and more durable glycemic control than metformin alone in patients with newly diagnosed type 2 diabetes, according to findings reported at the annual meeting of the European Association for the Study of Diabetes.

Fewer patients treated with the combination than with metformin monotherapy experienced “treatment failure” (43.6% vs. 62.1%, respectively) during the initial study period. The time-to-treatment failure, which was defined as an hemoglobin A_1c of at least 7% (53 mmol/L) or higher on two occasions 3 months apart, was estimated to be beyond the study’s duration, at 61·9 months, for the combination and a median of 36.1 months in the monotherapy group.

Moreover, there was a significant (P less than .0001) 49% reduction in the relative risk for the time-to-initial-treatment failure in the early combination treatment group, compared with the monotherapy group, during the 5-year study period. The time-to-second-treatment failure was also longer in patients who received initial combination therapy (hazard ratio, 0.74; P less than .0001).

These results of the VERIFY (Vildagliptin Efficacy in Combination With Metformin for Early Treatment of Type 2 Diabetes) study, which were published simultaneously in the Lancet, provide the first real evidence to support the use of combination therapy rather than the current standard of metformin alone in the initial treatment of type 2 diabetes.

VERIFY was a phase 4, randomized, parallel-group study designed to compare the durability of glycemic control achieved with a combination of vildagliptin plus metformin or metformin alone in treatment-naive patients with type 2 diabetes.

At a press briefing, three members of the VERITY steering committee explained the rationale, design, results, and implications of the study.

EASD president David R. Matthews, DPhil, FRCP, who is emeritus professor at the Oxford Centre for Diabetes, Endocrinology and Metabolism at the University of Oxford (England), observed that the study aimed to answer three important questions: Do patients with type 2 diabetes benefit from having combination treatment from the start of their pharmacologic management, and if so, is this more beneficial than a step-up approach, and ultimately, “does it really matter?”

Sara Freeman/MDedge News

A typical cohort of patients was included, said Michael Stumvoll, MD, of the University Hospital Leipzig (Germany). Patients had to be aged between 18 and 70 years, have a body mass index of 22-40 kg/m², and an hemoglobin A_1c level of 6.5%-7.5%. This “rather narrow range” was decided “on purpose to really fulfill the idea of having newly diagnosed [type 2 diabetes]”, Dr. Stumvoll noted. In addition, patients had to have adequate renal function, have been diagnosed with type 2 diabetes in the past 2 years, and be drug naive or have received no more than 4 weeks of metformin.

In all, 2,001 patients from 254 centers in 34 countries were included, with 998 randomized to initial treatment with vildagliptin and metformin and 1,003 to receive metformin alone after an initial run-in phase during which the dose of metformin was up-titrated from 500 to 1,500 mg/day. The study ran for 5 years, with treatment intensified if there was a loss of glycemic control at the discretion of the study investigators – first vildagliptin was added to patients taking metformin monotherapy, then insulin, if needed.

There were no safety concerns: A similar percentage of patients in the early combination and initial monotherapy arms experienced an adverse event (83.5% vs. 83.2%, respectively), a serious adverse event (16.6% vs. 18.3%), a drug-related adverse event (15.9% vs. 14.3%), a severe adverse event (10.5% vs. 10.6%), and adverse events leading to discontinuation of treatment (4.1% vs. 5.3%) or death (13 vs. 9 patients). There was no difference in the change in body weight, and rates of hypoglycemia were 1.3% and 0.9%, respectively.

Adjudication and an independent data-monitoring committee were set up after cardiovascular events occurred in a few patients, although this was not a cardiovascular outcomes trials, Dr. Matthews stressed. There were fewer absolute cumulative adjudicated events in the early combination arm, compared with the initial monotherapy arm (30 vs. 44, respectively), and the time to the first adjudicated macrovascular event favored early combination over initial monotherapy (2.4% vs. 3.3%; HR, 0.71).

“There is a big caveat here,” said Dr. Matthews, “these are very small numbers and wide confidence intervals and the P value is .194.” Although “it is not a significant finding, and it was never intended to be a significant finding,” it gives “an indication that we absolutely should be looking at this.”

Sara Freeman/MDedge News

Stefano Del Prato, MD, of the University of Pisa (Italy), noted that “there has been a lot of discussion around initial combination therapy for type 2 diabetes,” and although there was a realization that multiple treatment might be necessary, there was no evidence for that. The results of the VERIFY trial, however, now provide some of the proof that this approach may be of benefit. Patients “benefit twice as much” with the combination therapy as they do with the monotherapy, Dr. Del Prato said. “There are twice as many patients retained under control with an early combination, compared with the monotherapy.” That means no longer “running after the patient losing control” he said, but “being proactive” and with a very low risk of hypoglycemia. The clinical implication is that there is now evidence for combination therapy as an initial approach for managing type 2 diabetes.

Novartis funded the study. Dr. Matthews has served on advisory boards or as a consultant for, and has given lectures for, Novartis and numerous other companies not related to the study. He is currently the president of the European Association for the Study of Diabetes. Dr. Stumvoll has received speaker's honoraria and consulting fees from Novartis and other companies. Dr. Del Prato serves or has served on advisory boards and speakers bureaus for, and received research support from, Novartis and numerous other companies.

To the Editor:

The increase in nontuberculous mycobacteria (NTM) infections over the last 3 decades likely is multifaceted, including increased clinical awareness, improved laboratory diagnostics, growing numbers of immunocompromised patients, and an aging population.^1,2 Historically, the majority of mycobacteria-related diseases are due to Mycobacterium tuberculosis, Mycobacterium bovis, and Mycobacterium leprae.³

Mycobacterium haemophilum is a slow-growing acid-fast bacillus (AFB) that differs from other Mycobacterium species in that it requires iron-supplemented media and incubation temperatures of 30°C to 32°C for culture. As these requirements for growth are not standard for AFB cultures, M haemophilum infection may be underrecognized and underreported.³Mycobacterium haemophilum infections largely are cutaneous and generally are seen in AIDS patients and bone marrow transplant recipients who are iatrogenically immunosuppressed.^4,5 No species-specific treatment guidelines exist²; however, triple-drug therapy combining a macrolide, rifamycin, and a quinolone for a minimum of 12 months often is recommended.

A 64-year-old man with a history of coronary artery disease, hypertension, hyperlipidemia, and acute myelogenous leukemia (AML) underwent allogenic stem cell transplantation. His posttransplant course was complicated by multiple deep vein thromboses, hypogammaglobulinemia, and graft-vs-host disease (GVHD) of the skin and gastrointestinal tract that manifested as chronic diarrhea, which was managed with chronic prednisone. Thirteen months after the transplant, the patient presented to his outpatient oncologist (M.K.) for evaluation of painless, nonpruritic, erythematous papules and nodules that had emerged on the right side of the chest, right arm, and left leg of approximately 2 weeks’ duration.

On review of systems by oncology, the patient denied any fevers, chills, or night sweats but noted chronic loose nonbloody stools without abdominal pain, likely related to the GVHD. The patient’s medications included prednisone 20 mg once daily, fluconazole, amitriptyline, atovaquone, budesonide, dabigatran, metoprolol, pantoprazole, rosuvastatin, senna glycoside, spironolactone, tramadol, and valacyclovir.

Physical examination revealed multiple singular erythematous nodules on the right side of the chest (Figure 1A), right arm (Figure 1B), and left leg. There was no regional lymphadenopathy. The patient was afebrile and hemodynamically stable. A biopsy of the arm performed to rule out leukemia cutis revealed a granulomatous dermatitis with numerous AFB (Figures 2A and 2B), which were confirmed on Ziehl-Neelsen staining (Figures 2C and 2D). The presence of AFB raised concern for a disseminated mycobacterial infection. The patient was admitted to our institution approximately 1 week after the outpatient biopsy was performed. He was evaluated by infectious diseases (B.H.) and was recommended for repeat biopsy with AFB culture and for initiation of intravenous antibiotics.

The patient was evaluated by the dermatology consultation service on hospital day 1. At the time of consultation, the lesions were still painless but had enlarged. Two new satellite lesions were noted on his other extremities. Due to the widespread distribution of the lesions, there was concern for disseminated disease. The relatively rapid onset of new lesions increased concern for infection with rapid-growing mycobacteria, including Mycobacterium abscessus, Mycobacterium fortuitum, and Mycobacterium chelonae. A detailed history revealed that the patient’s wife had a fish tank, which supported the inclusion of Mycobacterium marinum in the differential; however, further questioning revealed that the patient never came in contact with the aquarium water. The initial outpatient biopsy had not been sent for culture. Following inpatient biopsy, the patient was initiated on empiric antimycobacterials, including imipenem, amikacin, clarithromycin, and levofloxacin. Computed tomography of the head was negative for cerebral involvement.

Acid-fast bacilli blood cultures were drawn per the recommendation from infectious diseases in an attempt to confirm disseminated disease; however, blood cultures remained negative. Tissue biopsy from the right arm was sent for AFB staining and culture. Many AFB were identified on microscopy, and growth was observed in the mycobacterial growth indicator tube after 6 days of incubation. The DNA probe was negative for M tuberculosis complex or Mycobacterium avium complex.

The patient was discharged on hospital day 6 on empiric therapy for rapid-growing mycobacteria while cultures were pending. The empiric regimen included intravenous imipenem 1 g every 6 hours, intravenous amikacin 1 g once daily, clarithromycin 500 mg every 12 hours, and levofloxacin 750 mg once daily. All solid media cultures were negative at the time of discharge.

The biopsy specimen proved difficult to culture on solid media using traditional methods. Three weeks after the inpatient biopsy, the microbiology laboratory reported that growth was observed on solid media that was incubated at 30°C and supplemented with iron. These findings were not characteristic of a rapidly growing mycobacteria (eg, M fortuitum, M chelonae, M abscessus) or M marinum but raised concern for infectionwith M haemophilum. Antimycobacterial treatment was adjusted to amikacin, clarithromycin, levofloxacin, and rifabutin.

Six weeks after the inpatient skin biopsy, final speciation confirmed infection with M haemophilum. The isolate proved susceptible to amikacin (minimal inhibitory concentration [MIC], 16), clarithromycin (MIC, 0.12), linezolid (MIC, <1), moxifloxacin (MIC, 0.5), rifabutin (MIC, <0.25), and trimethoprim-sulfamethoxazole (MIC, 0.5/9.5). The isolate was resistant to ciprofloxacin (MIC, 4), ethambutol (MIC, >16), and rifampin (MIC, 2). Based on these findings, an infectious disease specialist modified the treatment regimen to azithromycin 600 mg once daily, moxifloxacin 400 mg once daily, and rifabutin 300 mg once daily. Azithromycin was substituted for clarithromycin in an attempt to minimize the gastrointestinal side effects of the antibiotics. The infectious disease specialist was concerned that the clarithromycin could exacerbate the patient’s chronic GVHD-associated diarrhea, which posed a challenge to the oncologist, who was attempting to manage the patient’s GVHD and minimize the use of additional prednisone. At the time of this change, the patient was doing well clinically and denied any active skin lesions.

Four months later, he developed new left-sided neck swelling. Computed tomography revealed nonspecific enhancement involving the skin and superficial subcutaneous tissues in the left anterior neck. He was referred to otolaryngology given concern for recurrent infection vs leukemia cutis. He underwent excisional biopsy. Pathology was negative for malignancy but demonstrated subcutaneous necrotizing granulomatous inflammation with a positive AFB stain. Tissue AFB cultures revealed moderate AFB on direct stain, but there was no AFB growth at 12 weeks. Clarithromycin was restarted in place of azithromycin to increase the potency of the antimycobacterial regimen. Cultures from this neck biopsy were negative after 12 weeks of incubation.

In addition to this change in antibiotic coverage, the patient’s medical oncologist tapered the patient’s immunosuppression considerably. The patient subsequently completed 12 months of therapy with clarithromycin, moxifloxacin, and rifabutin starting from the time of the neck biopsy. He remained free of recurrence of mycobacterial infection for nearly 2 years until he died from an unrelated illness.

Nontuberculous mycobacteria are an ubiquitous environmental group.² Sources include soil and natural water (M avium), fish tanks and swimming pools (M marinum), and tap water and occasionally domestic animals (Mycobacterium kansasii). Additionally, rapidly growing NTM such as M abscessus, M chelonae, and M fortuitum have been isolated from soil and natural water supplies.³

Mycobacterium haemophilum is a fastidious organism with a predilection for skin of the chest and extremities. Iatrogenically or inherently immunocompromised patients are most commonly affected^6-11; however, there also have been reports in healthy patients.^12,13 Infections typically present as painless erythematous papules or nodules that eventually suppurate, ulcerate, and become painful. Presentations involving Fitz-Hugh–Curtis syndrome,¹³ new B-cell lymphoma,¹⁰ and lymphadenitis¹² also have been described. Beyond cutaneous involvement, M haemophilum has been cultured from bone, the synovium, the lungs, and the central nervous system.^4,9 The majority of morbidities occur in patients with lung involvement.⁴ Therefore, even patients presenting with isolated cutaneous disease require close follow-up.

Mycobacterium haemophilum is a slowly proliferating organism that is unable to grow in standard egg-potato (Lowenstein-Jensen) medium or agar base (Middlebrook 7H10 or 7H11 agar) without iron supplementation (ferric ammonium citrate, hemin, or hemoglobin). It also requires temperatures of 30°C to 32°C for growth. Its iron requisite is unique, but species such as M marinum and Mycobacterium ulcerans also share reduced temperature requirements. Without a high index of suspicion, growth often is absent because standard Mycobacterium culture techniques will not foster organism growth. Our case demonstrated that special culture instructions must be relayed to the laboratory, even in the face of positive AFB smears. Failure to request hemin and modified incubation temperatures may have contributed to the negative AFB blood culture in our patient.

Due to the relatively rare incidence of M haemophilum infection, there are no known randomized controlled trials guiding antibiotic regimens. Infectious disease specialists often treat empirically with triple-drug therapy derived from locally reported species susceptibilities. The largest case series to date did not identify resistance to amikacin, ciprofloxacin, or clarithromycin.⁴ Our case identified a novel finding of ciprofloxacin and rifampin resistance, which may highlight the emergence of a newly resistant strain of M haemophilum. Of note, one case of rifampin resistance has been reported, but the culture was drawn from a postmortem specimen in the setting of previously rifampin-sensitive isolates.⁴ Empiric therapies should be guided by hospital susceptibility reports and expert consultation.

Coinfection with 2 or more NTM—including M tuberculosis, M leprae, and M fortuitum—has been reported.^8,14 Temporally distinct coinfections with M leprae and M haemophilum also have been described.¹⁵ Thus, practitioners should have a low threshold for repeat cultures in the context of new cutaneous nodules or granulomas, not only to detect concomitant infections but also to identify resistance patterns that might explain recurrent or recalcitrant disease. Immune reconstitution inflammatory syndrome also must be considered with new or worsening lesions, especially in the first months of therapy, as this is a common occurrence when immunosuppressive regimens are tapered to help manage infections.

In conclusion, M haemophilum is an underrecognized infection that presents as cutaneous nodules or lymphadenitis in immunocompromised or healthy individuals. Diagnosis requires a high index of suspicion because its unique growth requirements necessitate special laboratory techniques. Our case represents a classic presentation of this NTM infection in a patient with AML following allogenic stem cell transplantation. Repeat cultures, workup of potentially disseminated infections, and close follow-up are requisite to minimizing morbidity and mortality. A multidisciplinary approach involving infectious disease, medical oncology, radiology, and dermatology best manages this type of infection.

To the Editor:

The increase in nontuberculous mycobacteria (NTM) infections over the last 3 decades likely is multifaceted, including increased clinical awareness, improved laboratory diagnostics, growing numbers of immunocompromised patients, and an aging population.^1,2 Historically, the majority of mycobacteria-related diseases are due to Mycobacterium tuberculosis, Mycobacterium bovis, and Mycobacterium leprae.³

Mycobacterium haemophilum is a slow-growing acid-fast bacillus (AFB) that differs from other Mycobacterium species in that it requires iron-supplemented media and incubation temperatures of 30°C to 32°C for culture. As these requirements for growth are not standard for AFB cultures, M haemophilum infection may be underrecognized and underreported.³Mycobacterium haemophilum infections largely are cutaneous and generally are seen in AIDS patients and bone marrow transplant recipients who are iatrogenically immunosuppressed.^4,5 No species-specific treatment guidelines exist²; however, triple-drug therapy combining a macrolide, rifamycin, and a quinolone for a minimum of 12 months often is recommended.

A 64-year-old man with a history of coronary artery disease, hypertension, hyperlipidemia, and acute myelogenous leukemia (AML) underwent allogenic stem cell transplantation. His posttransplant course was complicated by multiple deep vein thromboses, hypogammaglobulinemia, and graft-vs-host disease (GVHD) of the skin and gastrointestinal tract that manifested as chronic diarrhea, which was managed with chronic prednisone. Thirteen months after the transplant, the patient presented to his outpatient oncologist (M.K.) for evaluation of painless, nonpruritic, erythematous papules and nodules that had emerged on the right side of the chest, right arm, and left leg of approximately 2 weeks’ duration.

On review of systems by oncology, the patient denied any fevers, chills, or night sweats but noted chronic loose nonbloody stools without abdominal pain, likely related to the GVHD. The patient’s medications included prednisone 20 mg once daily, fluconazole, amitriptyline, atovaquone, budesonide, dabigatran, metoprolol, pantoprazole, rosuvastatin, senna glycoside, spironolactone, tramadol, and valacyclovir.

Physical examination revealed multiple singular erythematous nodules on the right side of the chest (Figure 1A), right arm (Figure 1B), and left leg. There was no regional lymphadenopathy. The patient was afebrile and hemodynamically stable. A biopsy of the arm performed to rule out leukemia cutis revealed a granulomatous dermatitis with numerous AFB (Figures 2A and 2B), which were confirmed on Ziehl-Neelsen staining (Figures 2C and 2D). The presence of AFB raised concern for a disseminated mycobacterial infection. The patient was admitted to our institution approximately 1 week after the outpatient biopsy was performed. He was evaluated by infectious diseases (B.H.) and was recommended for repeat biopsy with AFB culture and for initiation of intravenous antibiotics.

The patient was evaluated by the dermatology consultation service on hospital day 1. At the time of consultation, the lesions were still painless but had enlarged. Two new satellite lesions were noted on his other extremities. Due to the widespread distribution of the lesions, there was concern for disseminated disease. The relatively rapid onset of new lesions increased concern for infection with rapid-growing mycobacteria, including Mycobacterium abscessus, Mycobacterium fortuitum, and Mycobacterium chelonae.

The expanded use of targeted anticancer agents such as sorafenib has revealed a growing spectrum of adverse cutaneous eruptions. We describe 3 patients with sorafenib-induced psoriasiform dermatitis and review the literature of only 10 other similar reported cases based on a search of PubMed, Web of Science, and American Society of Clinical Oncology abstracts using the terms psoriasis or psoriasiform dermatitis and sorafenib.^1-10 We seek to increase awareness of this particular drug eruption in response to sorafenib and to describe potential effective treatment options, especially when sorafenib cannot be discontinued.

Case Reports

Patient 1
A 68-year-old man with chronic hepatitis B infection and hepatocellular carcinoma (HCC) was started on sorafenib 400 mg daily. After 2 months of treatment, he developed painful hyperkeratotic lesions on the bilateral palms and soles with formation of calluses and superficial blisters on an erythematous base that was consistent with hand-foot skin reaction (HFSR). He also had numerous erythematous thin papules and plaques with adherent white scale and yellow crust on the bilateral thighs, lower legs, forearms, dorsal hands, abdomen, back, and buttocks (Figure 1). He had no personal or family history of psoriasis, and blood tests were unremarkable. Histologic analysis of punch biopsies from the buttocks and right leg revealed focal parakeratosis with neutrophils and serous crust, acanthosis, mild spongiosis, and lymphocytes at the dermoepidermal junction and surrounding dermal vessels, consistent with psoriasiform dermatitis (Figure 2). Sorafenib was discontinued and the eruption began to resolve within a week. A lower dose of sorafenib (200 mg daily) was attempted and the psoriasiform eruption recurred.

Patient 2
An 82-year-old man with chronic hepatitis B infection and HCC with lung metastasis was treated with sorafenib 400 mg daily. One week after treatment, he developed painful, thick, erythematous lesions on acral surfaces, consistent with HFSR. The sorafenib dose was decreased to 200 mg daily and HFSR resolved. Four months later, he developed well-demarcated, erythematous, scaly plaques with peripheral pustules on the right thigh (Figure 3) and right shin. He had no personal or family history of psoriasis, and blood tests were unremarkable. Samples from the pustules were taken for bacterial culture and fungal stain, but both were negative. Histologic analysis of a punch biopsy from the right thigh revealed necrotic parakeratosis, spongiform pustules, mild acanthosis, and a perivascular lymphocytic infiltrate with many neutrophils in the dermis. These findings suggested a diagnosis of pustular psoriasis, pustular drug eruption, or acute generalized exanthematous pustulosis. Treatment was initiated with mometasone cream. The patient subsequently developed hemoptysis and ascites from sorafenib. Sorafenib was discontinued and his skin eruption gradually resolved.

Comment

Sorafenib is an oral tyrosine kinase inhibitor that blocks tumor cell proliferation and angiogenesis due to its activity against vascular endothelial growth factor (VEGF) receptor, platelet-derived growth factor receptor, stem cell growth factor receptor, and rapidly accelerated fibrosarcoma kinases.¹¹ It is primarily used for the treatment of solid tumors, such as advanced renal cell carcinoma, unresectable HCC, and thyroid carcinoma, and more recently has been expanded for treatment of AML due to potential inhibition of FMS-like tyrosine kinase 3 receptor. Although dermatologic toxicity is a common adverse event during treatment with sorafenib,¹¹ reports of psoriasiform drug eruptions are rare.

Review of Cases
Based on our literature search, there are 10 previously reported cases of psoriasiform drug eruption secondary to sorafenib. Of the 13 total cases (including the 3 patients in this report), 7 patients had a history of psoriasis; most were middle-aged men; and the treatment with sorafenib was for solid tumors, primarily HCC with the exception of patient 3 from the current report who was treated for AML (Table). In all cases, the dose of sorafenib ranged from 200 to 800 mg daily.

Vascular endothelial growth factor is overexpressed on psoriatic keratinocytes, contributes to epidermal hyperplasia, and induces angiogenesis in the dermis.¹² The development of psoriasiform eruptions in patients treated with sorafenib seems paradoxical, as this drug has been considered as potential therapy for psoriasis due to its ability to block VEGF receptor signaling. Indeed, an improvement of psoriasis has been reported in 1 case of a patient treated with sorafenib¹³ and in multiple patients with psoriasis treated with other VEGF antagonists (eg, bevacizumab).¹⁴ The underlying mechanisms by which sorafenib induced or exacerbated psoriasis are not entirely clear. Palmoplantar hyperkeratosis, keratosis pilaris–like eruption, multiple cysts, eruptive keratoacanthomas, and squamous cell carcinoma have been described in patients treated with sorafenib, supporting the hypothesis that treatment with sorafenib alters keratinocyte proliferation and differentiation.¹⁵ In addition, B-Raf inhibitors such as imatinib are known to induce or exacerbate psoriasiform dermatitis.¹⁶ The activity of sorafenib resulting in psoriasis may be specific to RAF kinase inhibition, as there are no reports in the literature that describe psoriasiform dermatitis with agents that preferentially block other sorafenib targets such as VEGF receptor, stem cell growth factor receptor, or platelet-derived growth factor receptor. Future studies are needed to fully elucidate the underlying mechanisms by which sorafenib induces or exacerbates psoriasiform dermatitis and whether the severity of the drug eruption correlates with the antitumor efficacy of sorafenib.

Conclusion

Although psoriasiform drug eruptions secondary to sorafenib are not life-threatening, they impact quality of life with associated pain, pruritus, infection, and limitation of daily activities. Dose reduction or discontinuation of sorafenib resulted in resolution of the psoriasiform dermatitis; however, as demonstrated in 3 cases (including patient 3),^1,2 psoriasiform dermatitis can be managed while maintaining the patient on sorafenib so that treatment of the malignancy is not compromised.

The expanded use of targeted anticancer agents such as sorafenib has revealed a growing spectrum of adverse cutaneous eruptions. We describe 3 patients with sorafenib-induced psoriasiform dermatitis and review the literature of only 10 other similar reported cases based on a search of PubMed, Web of Science, and American Society of Clinical Oncology abstracts using the terms psoriasis or psoriasiform dermatitis and sorafenib.^1-10 We seek to increase awareness of this particular drug eruption in response to sorafenib and to describe potential effective treatment options, especially when sorafenib cannot be discontinued.

Case Reports

Patient 1
A 68-year-old man with chronic hepatitis B infection and hepatocellular carcinoma (HCC) was started on sorafenib 400 mg daily. After 2 months of treatment, he developed painful hyperkeratotic lesions on the bilateral palms and soles with formation of calluses and superficial blisters on an erythematous base that was consistent with hand-foot skin reaction (HFSR). He also had numerous erythematous thin papules and plaques with adherent white scale and yellow crust on the bilateral thighs, lower legs, forearms, dorsal hands, abdomen, back, and buttocks (Figure 1). He had no personal or family history of psoriasis, and blood tests were unremarkable. Histologic analysis of punch biopsies from the buttocks and right leg revealed focal parakeratosis with neutrophils and serous crust, acanthosis, mild spongiosis, and lymphocytes at the dermoepidermal junction and surrounding dermal vessels, consistent with psoriasiform dermatitis (Figure 2). Sorafenib was discontinued and the eruption began to resolve within a week. A lower dose of sorafenib (200 mg daily) was attempted and the psoriasiform eruption recurred.

Patient 2
An 82-year-old man with chronic hepatitis B infection and HCC with lung metastasis was treated with sorafenib 400 mg daily. One week after treatment, he developed painful, thick, erythematous lesions on acral surfaces, consistent with HFSR. The sorafenib dose was decreased to 200 mg daily and HFSR resolved. Four months later, he developed well-demarcated, erythematous, scaly plaques with peripheral pustules on the right thigh (Figure 3) and right shin. He had no personal or family history of psoriasis, and blood tests were unremarkable. Samples from the pustules were taken for bacterial culture and fungal stain, but both were negative. Histologic analysis of a punch biopsy from the right thigh revealed necrotic parakeratosis, spongiform pustules, mild acanthosis, and a perivascular lymphocytic infiltrate with many neutrophils in the dermis. These findings suggested a diagnosis of pustular psoriasis, pustular drug eruption, or acute generalized exanthematous pustulosis. Treatment was initiated with mometasone cream. The patient subsequently developed hemoptysis and ascites from sorafenib. Sorafenib was discontinued and his skin eruption gradually resolved.

Comment

Sorafenib is an oral tyrosine kinase inhibitor that blocks tumor cell proliferation and angiogenesis due to its activity against vascular endothelial growth factor (VEGF) receptor, platelet-derived growth factor receptor, stem cell growth factor receptor, and rapidly accelerated fibrosarcoma kinases.¹¹ It is primarily used for the treatment of solid tumors, such as advanced renal cell carcinoma, unresectable HCC, and thyroid carcinoma, and more recently has been expanded for treatment of AML due to potential inhibition of FMS-like tyrosine kinase 3 receptor. Although dermatologic toxicity is a common adverse event during treatment with sorafenib,¹¹ reports of psoriasiform drug eruptions are rare.

Review of Cases
Based on our literature search, there are 10 previously reported cases of psoriasiform drug eruption secondary to sorafenib. Of the 13 total cases (including the 3 patients in this report), 7 patients had a history of psoriasis; most were middle-aged men; and the treatment with sorafenib was for solid tumors, primarily HCC with the exception of patient 3 from the current report who was treated for AML (Table). In all cases, the dose of sorafenib ranged from 200 to 800 mg daily. In 5 cases, HFSR preceded (as with patient 2 in the current report) or presented concurrently (as with patient 1 in the current report) with the onset of psoriasiform rash.^1,3,5

Of eight recommended prevention strategies for repeat severe pneumonia in children with neurologic impairment, only one – dental care – was found to be effective, according to findings published in Pediatrics.

Five of the remaining seven strategies – gastrostomy tube placement, chest physiotherapy, outpatient antibiotics before hospitalization, and clinic visit before and after index hospitalization – were associated with increased recurrence, Jody L. Lin, MD, of the department of pediatrics at Stanford (Calif.) University, and colleagues reported. Oral secretion management and gastric acid suppression were associated with increased risk, but to a lesser extent.

The researchers examined the outcomes of the prevention strategies because, although children with neurologic impairment are more susceptible to community-acquired pneumonia, current guidelines are based mostly on expert opinion. The study included 3,632 children aged 21 years or younger with neurologic impairment and at least one hospitalization for pneumonia, who were enrolled in the California Children’s Services program between July 1, 2009, and June 30, 2014.

Propensity-score matching based on factors such as age, sex, household income, as well as characteristics of index hospitalization, showed decreased odds of recurrence only with receipt of dental care (adjusted odds ratio, 0.64; 95% confidence interval, 0.49-0.85), whereas increased odds were seen with other recommended prevention strategies, such as chest physiotherapy (aOR, 2.03; 95% CI, 1.29-3.20), receipt of antibiotics before hospitalization (aOR, 1.42; 95% CI, 1.06-1.92), and clinic visit before (aOR, 1.30; 95% CI, 1.11-1.52) and after index hospitalization (aOR, 1.72; 95% CI, 1.35-2.20).

The greatest increased odds, however, were seen with new gastrostomy tube placement (aOR, 2.15; 95% CI, 1.63-2.85).

The investigators noted that the biggest limitation of this study was the potential for residual confounding by indication even after adjustment, whereby certain interventions were provided to patients deemed more clinically severe to begin with. A strength of the study is its longitudinal nature.

“Our results suggest that more attention should be paid to dental health for children with [neurologic impairment],” the researchers wrote, although they noted that dental care “remains the most common unmet health care need” for children with special health care needs.

The findings also “support a clinical trial of dental care for prevention of severe pneumonia in children with [neurologic impairment] and do not support the widespread use of gastrostomy tubes for that purpose,” they added.

The study was funded by the National Institutes of Health. Dr. Lin received support from the NIH and the Clinical Excellence Research Center. The authors reported that they had no conflicts of interest.

The FP suspected leukocytoclastic vasculitis (LCV) and, with the patient’s consent, performed a 4-mm punch biopsy on a well-developed lesion on the abdomen. Biopsies on the abdomen heal faster than the legs and may provide a better specimen to the pathologist. (See the Watch & Learn video on “Punch biopsy.”)

The biopsy confirmed the diagnosis of LCV. This is the most commonly seen form of small vessel vasculitis. LCV causes acute inflammation and necrosis of venules in the dermis. The term leukocytoclastic vasculitis describes the histologic pattern produced when leukocytes break apart into fragments. The purpura begins as asymptomatic localized areas of cutaneous hemorrhage that become palpable.

Discrete lesions are most commonly seen on the lower extremities, but they may occur on any dependent area. Small lesions may itch and be painful, but nodules, ulcers, and bullae may be more painful. Lesions appear in crops, last for 1 to 4 weeks, and may heal with residual scarring and hyperpigmentation. Patients may experience a single episode caused by a drug reaction or viral infection or have multiple episodes associated with rheumatologic diseases. LCV usually is self-limited and confined to the skin.

To make the diagnosis, look for the presence of 3 or more of the following:

• age > 16 years;
• use of a possible offending drug in temporal relation to the symptoms;
• palpable purpura;
• maculopapular rash; and
• neutrophils around an arteriole or venule in a biopsy of a skin lesion.

In this case, the use of ibuprofen was the most likely precipitating event. Blood and urine tests did not show any renal or other organ system involvement. The patient was warned to not use ibuprofen in the future and that acetaminophen is a safer option for him. He was given topical triamcinolone cream 0.1% to apply twice daily for symptomatic relief. In this case, oral prednisone was not prescribed because the numerous potential adverse effects of prednisone outweighed the benefits. The vasculitis resolved in 4 weeks without any sequelae.

Adolescents’ past 30-day use of e-cigarettes more than doubled from 2017 to 2019, and in 2019 almost 12% of high school seniors reported that they were vaping every day, according to data from the Monitoring the Future surveys.

Daily use – defined as vaping on 20 or more of the previous 30 days – was reported by 6.9% of 10th-grade and 1.9% of 8th-grade respondents in the 2019 survey, which was the first time use in these age groups was assessed. “The substantial levels of daily vaping suggest the development of nicotine addiction,” Richard Miech, PhD, and associates said Sept. 18 in the New England Journal of Medicine.

From 2017 to 2019, e-cigarette use over the previous 30 days increased from 11.0% to 25.4% among 12th graders, from 8.2% to 20.2% in 10th graders, and from 3.5% to 9.0% of 8th graders, suggesting that “current efforts by the vaping industry, government agencies, and schools have thus far proved insufficient to stop the rapid spread of nicotine vaping among adolescents,” the investigators wrote.

By 2019, over 40% of 12th-grade students reported ever using e-cigarettes, along with more than 36% of 10th graders and almost 21% of 8th graders. Corresponding figures for past 12-month use were 35.1%, 31.1%, and 16.1%, they reported.

“New efforts are needed to protect youth from using nicotine during adolescence, when the developing brain is particularly susceptible to permanent changes from nicotine use and when almost all nicotine addiction is established,” the investigators wrote.

The analysis was funded by a grant from the National Institute on Drug Abuse to Dr. Miech.

From 2017 to 2019, e-cigarette use over the previous 30 days increased from 11.0% to 25.4% among 12th graders, from 8.2% to 20.2% in 10th graders, and from 3.5% to 9.0% of 8th graders, suggesting that “current efforts by the vaping industry, government agencies, and schools have thus far proved insufficient to stop the rapid spread of nicotine vaping among adolescents,” the investigators wrote.

By 2019, over 40% of 12th-grade students reported ever using e-cigarettes, along with more than 36% of 10th graders and almost 21% of 8th graders. Corresponding figures for past 12-month use were 35.1%, 31.1%, and 16.1%, they reported.

“New efforts are needed to protect youth from using nicotine during adolescence, when the developing brain is particularly susceptible to permanent changes from nicotine use and when almost all nicotine addiction is established,” the investigators wrote.

The analysis was funded by a grant from the National Institute on Drug Abuse to Dr. Miech.

A daily polypill regimen improved cardiovascular risk factors in a socioeconomically vulnerable minority population, in a randomized controlled trial.

Patients at a federally qualified community health center in Alabama who received treatment with a combination pill for 1 year had greater reductions in systolic blood pressure and LDL cholesterol than did patients who received usual care, according to results published online on Sept. 19 in the New England Journal of Medicine.

“The simplicity and low cost of the polypill regimen make this approach attractive” when barriers such as lack of income, underinsurance, and difficulty attending clinic visits are common, said first author Daniel Muñoz, MD, of Vanderbilt University in Nashville, and coinvestigators. The investigators obtained the pills at a cost of $26 per month per participant.
 

People with low socioeconomic status and those who are nonwhite have high cardiovascular mortality, and the southeastern United States and rural areas have disproportionately high levels of cardiovascular disease burden, according to the investigators. The rates at which people with low socioeconomic status receive treatment for hypertension and hypercholesterolemia – leading cardiovascular disease risk factors – “are strikingly low,” Dr. Muñoz and colleagues said.

To assess the effectiveness of a polypill-based strategy in an underserved population with low socioeconomic status, the researchers conducted the randomized trial.

They enrolled 303 adults without cardiovascular disease, and 148 of the patients were randomized to receive the polypill, which contained generic versions of atorvastatin (10 mg), amlodipine (2.5 mg), losartan (25 mg), and hydrochlorothiazide (12.5 mg). The remaining 155 patients received usual care. All participants scheduled 2-month and 12-month follow-up visits.

The participants had an average age of 56 years, 60% were women, and more than 95% were black. More than 70% had an annual household income of less than $15,000. Baseline characteristics of the treatment groups did not significantly differ.

At baseline, the average BP was 140/83 mm Hg, and the average LDL cholesterol level was 113 mg/dL.

In all, 91% of the participants completed the 12-month trial visit. Average systolic BP decreased by 9 mm Hg in the group that received the polypill, compared with 2 mm Hg in the group that received usual care. Average LDL cholesterol level decreased by 15 mg/dL in the polypill group, versus 4 mg/dL in the usual-care group.

Changes in other medications

Clinicians discontinued or reduced doses of other antihypertensive or lipid-lowering medications in 44% of the patients in the polypill group and none in the usual-care group. Clinicians escalated therapy in 2% of the participants in the polypill group and in 10% of the usual-care group.

Side effects in participants who received the polypill included a 1% incidence of myalgias and a 1% incidence of hypotension or light-headedness. Liver function test results were normal.

Five serious adverse events that occurred during the trial – two in the polypill group and three in the usual-care group – were judged to be unrelated to the trial by a data and safety monitoring board.

The authors noted that limitations of the trial include its open-label design and that it was conducted at a single center.

“It is important to emphasize that use of the polypill does not preclude individualized, add-on therapies for residual elevations in blood-pressure or cholesterol levels, as judged by a patient’s physician,” said Dr. Muñoz and colleagues. “We recognize that a ‘one size fits all’ approach to cardiovascular disease prevention runs counter to current trends in precision medicine, in which clinical, genomic, and lifestyle factors are used for the development of individualized treatment strategies. Although the precision approach has clear virtues, a broader approach may benefit patients who face barriers to accessing the full advantages of precision medicine.”

The study was supported by grants from the American Heart Association Strategically Focused Prevention Research Network and the National Institutes of Health. One author disclosed personal fees from Novartis outside the study.

Higher body mass index and moderate – but not heavy – drinking may increase the risk of individuals with psoriasis going on to develop psoriatic arthritis, a study has found.

Around one in five people with psoriasis will develop psoriatic arthritis (PsA), wrote Amelia Green of the University of Bath (England) and coauthors in the British Journal of Dermatology.

Previous studies have explored possible links between obesity, alcohol consumption, or smoking, and an increased risk of developing psoriatic arthritis. However, some of these studies found conflicting results or had limitations such as measuring only a single exposure.

In a cohort study, the Ms. Green and her colleagues examined data from the U.K. Clinical Practice Research Datalink for 90,189 individuals with psoriasis, 1,409 of whom were subsequently also diagnosed with psoriatic arthritis.

The analysis showed a significant association between increasing body mass index (BMI) and increasing odds of developing psoriatic arthritis. Compared with individuals with a BMI below 25 kg/m², those with a BMI of 25.0-29.9 had a 79% greater odds of psoriatic arthritis, those with a BMI of 30.0-34.9 had a 2.10-fold greater odds, and those with a BMI at or above 35 had a 2.68-fold greater odds of developing psoriatic arthritis (P for trend less than .001). Adjustment for potential confounders such as sex, age, duration and severity of psoriasis, diabetes, smoking, and alcohol use slightly attenuated the association, but it remained statistically significant.

Researchers also examined the cumulative effect of lower BMIs over time, and found that over a 10-year period, reductions in BMI were associated with reductions in the risk of developing PsA, compared with remaining at the same BMI over that time.

“Here we have shown for the first time that losing weight over time could reduce the risk of developing PsA in a population with documented psoriasis,” the authors wrote. “As the effect of obesity on the risk of developing PsA may in fact occur with some delay and change over time, our analysis took into account both updated BMI measurements over time and the possible nonlinear and cumulative effects of BMI, which have not previously been investigated.”

Commenting on the mechanisms underlying the association between obesity and the development of PsA, the authors noted that adipose tissue is a source of inflammatory mediators such as adipokines and proinflammatory cytokines, which could lead to the development of PsA. Increasing body weight also could cause microtraumas of the connective tissue between tendon and bone, which may act as an initiating pathogenic event for PsA.

Moderate drinkers – defined as 0.1–3.0 drinks per day ­– had 57% higher odds of developing PsA when compared with nondrinkers, but former drinkers or heavy drinkers did not have an increased risk.

The study also didn’t see any effect of either past or current smoking on the risk of PsA, although there was a nonsignificant interaction with obesity that hinted at increased odds.

“While we found no association between smoking status and the development of PsA in people with psoriasis, further analysis revealed that the effect of smoking on the risk of PsA was possibly mediated through the effect of BMI on PsA; in other words, the protective effect of smoking may be associated with lower BMI among smokers,” the authors wrote.

Patients who developed PsA were also more likely to be younger (mean age of 44.7 years vs. 48.5 years), have severe psoriasis, and have had the disease for a shorter duration.

The study was funded by the National Institute for Health Research, and the authors declared grants from the funder during the conduct of the study. No other conflicts of interest were declared.

Two great tastes that cause cancer together

Spaghetti and meatballs. They go together like chocolate and peanut butter. It almost feels wrong to eat one without the other; but if you’re worried about cancer, you may have to go meatless.

artisteer/iStock/Getty Images

The latest blow to an enjoyable meal comes courtesy of a study published in Molecular Nutrition & Food Research, which tested how lycopene – a carotenoid found in tomatoes that has notable anticancer properties – is absorbed by the body when in the presence of iron, which meat contains plenty of. When the study subjects drank a tomato-based shake infused with iron, lycopene was far less present in the blood and digestive system than in subjects who drank an iron-free tomato shake.

The study authors claim that either the iron is oxidizing with the lycopene or that the iron turns the mix of tomato and fat into something like separated salad dressing, preventing everything from mixing together when it enters the body.
 

Tastes like chicken

It’s an enduring oncologic mystery: How can some cancer cells endure what should be a lethal therapeutic beating, only to bounce off the canvas after an eight-count to deliver a devastating relapse-counterpunch of their own?

A new study offers an unsavory answer: cannibalism.

Turns out that dining on one’s weaker cancer cell neighbors during a chemotherapy barrage provides just enough energy to rope-a-dope and stage a late-round comeback.

Breast cancer cells with wild-type TP53 genes are particularly prone to revival after taking a beating at the hands of doxorubicin or other chemotherapy drugs. Like many of their cancerous compatriots, they retreat to a corner of the therapy ring during chemo and go gloves up in a state of senescence.

But researchers at Tulane University noticed that, in the midst of that pharmaceutical pummeling, those senescent wild-type TP53 cells start doing something that their other senescent, cancerous neighbors don’t: They engulf other cancer cells. Why? Seems those breast cancer cells with the wild-type TP53 gloves are equipped with gene expression programs similar to macrophages.

What’s more, the cannibals’ appetite for fellow cells appears to confer a survival advantage when the chemo rounds end.

We at the Bureau of LOTME will resist the impulse to ring out this item with a tasteless Donner Party punchline. Instead, we’ll indulge our high-brow inner child by retooling an elementary school comedy classic.

Why don’t cancer-cell cannibals eat cancer-cell comedians? They taste funny.
 

Poop, what is it good for?

One thing you can cross off the list: Cutting meat.

That might seem pretty obvious, but there’s actually a bit of history here. In a book published in 1998, anthropologist Wade Davis shared an account of an elderly Inuit man trapped alone in a storm. He had no tools and no food, so he made a knife out of his own frozen stool and used it to kill and butcher a dog.

That story, which has since become something of an urban legend, directly inspired the career of another anthropologist, Metin Eren, PhD, of Kent State University in Ohio. As director of the school’s laboratory of experimental archaeology, Dr. Eren decided that the time had come to prove or disprove the poop-knife hypothesis.

First, he and his team had to make such a knife. To produce the needed raw materials, Dr. Eren went on an 8-day “Arctic diet” that included lots of beef, turkey, and salmon, with some applesauce and butternut squash risotto thrown in, while a colleague stuck to a more Western diet. Their samples were then frozen to –58° F and sharpened with metal files.

“I was surprised at how hard human feces could get when frozen,” Dr. Eren told Live Science. “I started to think, ‘Oh my gosh, this might actually work!’ ”

The team’s attempts to cut refrigerated pig hide, however, were not successful. “Like a crayon, it just left brown streaks on the meat – no slices at all,” he said.

Today’s lesson? Don’t meat your heroes or their poop knives; they’re sure to disappoint you.

He had no tools and no food, so he made a knife out of his own frozen stool and used it to kill and butcher a dog.

That story, which has since become something of an urban legend, directly inspired the career of another anthropologist, Metin Eren, PhD, of Kent State University in Ohio. As director of the school’s laboratory of experimental archaeology, Dr. Eren decided that the time had come to prove or disprove the poop-knife hypothesis.

First, he and his team had to make such a knife. To produce the needed raw materials, Dr. Eren went on an 8-day “Arctic diet” that included lots of beef, turkey, and salmon, with some applesauce and butternut squash risotto thrown in, while a colleague stuck to a more Western diet. Their samples were then frozen to –58° F and sharpened with metal files.

“I was surprised at how hard human feces could get when frozen,” Dr. Eren told Live Science. “I started to think, ‘Oh my gosh, this might actually work!’ ”

The team’s attempts to cut refrigerated pig hide, however, were not successful. “Like a crayon, it just left brown streaks on the meat – no slices at all,” he said.

Today’s lesson? Don’t meat your heroes or their poop knives; they’re sure to disappoint you.

Two great tastes that cause cancer together

Spaghetti and meatballs. They go together like chocolate and peanut butter. It almost feels wrong to eat one without the other; but if you’re worried about cancer, you may have to go meatless.

The latest blow to an enjoyable meal comes courtesy of a study published in Molecular Nutrition & Food Research, which tested how lycopene – a carotenoid found in tomatoes that has notable anticancer properties – is absorbed by the body when in the presence of iron, which meat contains plenty of. When the study subjects drank a tomato-based shake infused with iron, lycopene was far less present in the blood and digestive system than in subjects who drank an iron-free tomato shake.

The study authors claim that either the iron is oxidizing with the lycopene or that the iron turns the mix of tomato and fat into something like separated salad dressing, preventing everything from mixing together when it enters the body.
 

Tastes like chicken

It’s an enduring oncologic mystery: How can some cancer cells endure what should be a lethal therapeutic beating, only to bounce off the canvas after an eight-count to deliver a devastating relapse-counterpunch of their own?

A new study offers an unsavory answer: cannibalism.

Turns out that dining on one’s weaker cancer cell neighbors during a chemotherapy barrage provides just enough energy to rope-a-dope and stage a late-round comeback.

Breast cancer cells with wild-type TP53 genes are particularly prone to revival after taking a beating at the hands of doxorubicin or other chemotherapy drugs. Like many of their cancerous compatriots, they retreat to a corner of the therapy ring during chemo and go gloves up in a state of senescence.

But researchers at Tulane University noticed that, in the midst of that pharmaceutical pummeling, those senescent wild-type TP53 cells start doing something that their other senescent, cancerous neighbors don’t: They engulf other cancer cells. Why? Seems those breast cancer cells with the wild-type TP53 gloves are equipped with gene expression programs similar to macrophages.

What’s more, the cannibals’ appetite for fellow cells appears to confer a survival advantage when the chemo rounds end.

We at the Bureau of LOTME will resist the impulse to ring out this item with a tasteless Donner Party punchline. Instead, we’ll indulge our high-brow inner child by retooling an elementary school comedy classic.

Why don’t cancer-cell cannibals eat cancer-cell comedians? They taste funny.
 

Poop, what is it good for?

One thing you can cross off the list: Cutting meat.
