Patients with cancer are at a high risk of venous thromboembolism (VTE)—in fact, it’s one of the leading causes of death in patients who receive systemic therapy for cancer. But as cancer treatment has evolved, have the incidence and risk of VTE changed too?

Researchers from Veterans Affairs Boston Healthcare System in Massachusetts conducted a study with 434,203 veterans to evaluate the pattern of VTE incidence over 16 years, focusing on the types of cancer, treatment, race and ethnicity, and other factors related to cancer-associated thrombosis (CAT).

In contrast with other large population studies, this study found the overall incidence of CAT remained largely stable over time. At 12 months, the incidence was 4.5%, with yearly trends ranging between 4.2% and 4.7%. “As expected,” the researchers say, the subset of patients receiving systemic therapy had a higher incidence of VTE at 12 months (7.7%) than did the overall cohort. The pattern was “particularly pronounced” in gynecologic, testicular, and kidney cancers, where the incidence of VTE was 2 to 3 times higher in the treated cohort compared with the overall cohort. 

Cancer type and diagnosis were the most statistically and clinically significant associations with CAT, with up to a 6-fold difference between cancer subtypes. The patients at the highest risk of VTE were those with pancreatic cancer and acute lymphoblastic leukemia.

Most studies have focused only on patients with solid tumors, but these researchers observed novel patterns among patients with hematologic neoplasms. Specifically, a higher incidence of VTE among patients with aggressive vs indolent leukemias and lymphomas. This trend, the researchers say, may be associated in part with catheter-related events.

Furthermore, the type of system treatment was associated with the risk of VTE, the researchers say, although to a lesser extent. Chemotherapy- and immunotherapy-based regimens had the highest risk of VTE, relative to no treatment. Targeted and endocrine therapy also carried a higher risk compared with no treatment but to a lesser degree.

The researchers found significant heterogeneity by race and ethnicity across cancer types. Non-Hispanic Black patients had about 20% higher risk of VTE compared with non-Hispanic White patients. Asian and Pacific Islander patients had about 20% lower risk compared with non-Hispanic White patients.

Male sex was also associated with VTE. However, “interestingly,” the researchers note, neighborhood-level socioeconomic factors and patients’ comorbidities were not associated with CAT but were associated with mortality.

Their results suggest that patient- and treatment-specific factors play a critical role in assessing the risk of CAT, and “ongoing efforts to identify these patterns are of utmost importance for risk stratification and prognostic assessment.”

As the number of female veterans continues to grow, the US Department of Veterans Affairs (VA) is adjusting by focusing more on breast/gynecological cancer and referring fewer cases to outside clinicians.

The VA’s effort reflects the reality that female veterans from the wars in Afghanistan and Iraq are approaching the ages—50s, 60s, and 70s—when cancer diagnoses become more common, said Sarah Colonna, MD, national medical director of breast oncology for VA's Breast and Gynecologic Oncology System of Excellence and an oncologist at the Huntsman Cancer Institute and Wahlen VA Medical Center in Salt Lake City, Utah. “This is preparation for the change that we know is coming.”

In response, the Association of VA Hematology/Oncology (AVAHO) is devoting a regional meeting in Tampa, Florida (July 29, 2023) to improving survivorship for patients with women’s cancers. “This meeting is designed to educate both cancer experts and primary care providers on the care of women who have already gone through breast and gynecological cancer treatment,” Colonna explained.

Adherence Challenges

Colonna will speak in a session about the importance of adherence to endocrine therapy. “When we prescribe endocrine therapy for breast cancer, we usually ask women to stay on it for 5 to 10 years, and sometimes that’s hard for them,” she said. “I’ll talk about tips and tricks to help women stay on endocrine therapy for the long haul because we know that is linked to better survival.”

Between two-thirds and three-quarters of women with breast cancer are advised to stay on endocrine drugs, she said, but the medications can be difficult to tolerate due to adverse effects such as hot flashes and sleep disturbances.

In addition, patients are often anxious about the medications. “Women are very leery of anything that changes or makes their hormones different,” Colonna noted. “They feel like it’s messing with something that is natural for them.”

Colonna urges colleagues to focus on their “soft skills,” the ability to absorb and validate the worries of patients. Instead of dismissing them, she said, focus on messages that acknowledge concerns but are also firm: “That’s real, that sucks. But we’ve got to do it.”

It’s also helpful to guide patients away from thinking that taking a pill every day means they’re sick. “I try to flip that paradigm: ‘You’re taking this pill every day because you have power over this thing that happened to you.’”

Education is also key, she said, so that patients “understand very clearly why this medication is important for them: It increases the chance of surviving breast cancer or it increases the chances that the cancer will never come back in your arm or in your breast. Then, whether they make a decision to take it or not, at least they’re making the choice with knowledge.”

As for adverse effects, Colonna said medications such as antidepressants and painkillers can relieve hot flashes, which can disturb sleep.

Identifying the best strategy to address adverse effects “requires keeping in frequent contact with the patient during the first 6 months of endocrine therapy, which are really critical,” she said. “Once they’ve been on it for a year, they can see the light at the end of the tunnel and hang in there even if they have adverse effects.”

Some guidelines suggest that no doctor visits are needed until the 6-month mark, but Colonna prefers to check in at the 4- to 6-week mark, even if it’s just via a phone call. Otherwise, “often they’ll stop taking the pill, and then you won’t know about it until you see them at 6 six months.” At that point, she said, a critical period for treatment has passed.

The Role of Nurse Navigators

In another session at the Tampa regional meeting, AVAHO president-elect Cindy Bowman, MSN, RN, OCN, will moderate a session about the role of nurse navigators in VA cancer care. She is the coordinator of the Cancer Care Navigation Program at the C. W. Bill Young VA Medical Center in Bay Pines, Florida.

“Veterans become survivors the day they’re diagnosed with cancer,” she said. Within the VA, cancer-care navigator teams developed over the past decade aim to help patients find their way forward through survivorship, she said, and nurses are crucial to the effort.

As Sharp and Scheid reported in a 2018 Journal Oncology Navigation Survivorship article, “research demonstrates that navigation can improve access to the cancer care system by addressing barriers, as well as facilitating quality care. The benefits of patient navigation for improving cancer patient outcomes is considerable.” McKenney and colleagues found that “patient navigation has been demonstrated to increase access to screening, shorten time to diagnostic resolution, and improve cancer outcomes, particularly in health disparity populations, such as women of color, rural populations, and poor women.” 

According to Bowman, “it has become standard practice to have nurse navigators be there each step of the way from a high suspicion of cancer to diagnosis and through the clinical workup into active treatment and survivorship.” Within the VA, she said, “the focus right now is to look at standardizing care that all VAs will be able to offer holistic, comprehensive cancer-care navigation teams.”

At the regional meeting, Bowman’s session will include updates from nurse navigators about helping patients through breast/gynecological cancer, abnormal mammograms, and survivorship.

Nurse navigators are typically the second medical professionals who talk to cancer patients after their physicians, Bowman said. The unique knowledge of oncology nurse navigators gives them invaluable insight into treatment plans and cancer drug regimens, she said.

“They’re able to sit down and discuss the actual cancer drug regimen with patients—what each of those drugs do, how they’re administered, the short-term and long-term side effects,” she said. “They have the knowledge about all aspects of cancer care that can really only come from somebody who’s specialty trained.”

Other sessions at the AVAHO regional meeting will highlight breast cancer and lymphedema, breast cancer and bone health; diet, exercise and cancer; sexual health for breast/gynecological cancer survivors; and imaging surveillance after diagnosis.

Key clinical point: Probiotic intake by breastfeeding mothers reduced atopic dermatitis (AD) incidence in children by half, whereas in children receiving probiotic supplementation, AD incidence decreased by 22% only.

Major finding: Probiotic intake by pregnant and breastfeeding mothers, pregnant and breastfeeding mothers and children, and pregnant mothers and children reduced the incidence of pediatric AD by 49% (relative risk [RR] 0.51; 95% CI 0.39-0.66), 39% (RR 0.61; 95% CI 0.43-0.86), and 27% (RR 0.73; 95% CI 0.63-0.86), respectively. Children receiving probiotics vs placebo had a 22% lower incidence of AD (RR 0.78; 95% CI 0.64-0.94).

Study details: Findings are from a systematic review and meta-analysis of 75 studies on the prophylactic (n = 8754 participants) or therapeutic (n = 2021 children) effects of probiotics in children age ≤ 18 years, including 17 studies involving 2844 children who received probiotics or placebo.

Key clinical point: A history of herpes zoster (HZ) infection is a predictive factor for the occurrence of HZ in patients with moderate-to-severe atopic dermatitis (AD) during upadacitinib therapy.

Major finding: The incidence of a history of HZ was significantly higher in patients with vs without the occurrence of HZ in the 15 mg upadacitinib (70% vs 3%), 30 mg upadacitinib (100% vs 10%), and overall (79% vs 5%) groups (all P < .01). HZ history was significantly associated with the occurrence of HZ during treatment in the 15 mg upadacitinib (adjusted odds ratio [aOR] 172) and overall (aOR 74.6) groups (both P < .01).

Study details: Findings are from a retrospective analysis of 112 patients aged ≥12 years with moderate-to-severe AD who received 15 mg upadacitinib (n = 78) or 30 mg upadacitinib (n = 34) daily for 3-9 months.

Key clinical point: Infants with atopic dermatitis (AD) experience significant bronchial obstruction regardless of disease severity, food sensitivity, and a history of recurrent wheezing.

Major finding: Tidal breath analysis revealed that the AD vs control group had significantly lower time to peak tidal expiratory flow (TPTEF; P = .001), exhaled volume to peak tidal expiratory flow (VPTEF; P = .001), TPTEF/expiratory time (P < .001), VPTEF/total expiratory volume (P < .001), expiratory flow when 25% of tidal volume remains in the lungs (P < .001), and respiratory rate (P = .007), with no differences observed within the AD group when these parameters were compared based on disease severity, food sensitivity, and a history of recurrent wheezing (all P > .05).

Study details: This prospective cross-sectional study included 150 infants aged 0-3 years with AD and 80 control infants of similar age without chronic disease, acute or chronic infection, history of prematurity, developmental delay, neurometabolic disease, or atopy.

Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Key clinical point: In patients with moderate-to-severe atopic dermatitis (AD), baricitinib with or without topical corticosteroids (TCS) resulted in rapid achievement of the recommended absolute Eczema Area and Severity Index (EASI) and SCORing of AD (SCORAD) outcomes, which were sustained until week 16.

Major finding: An EASI score of ≤7 and a SCORAD score of <25 were achieved by significantly more patients receiving baricitinib (2 or 4 mg) vs placebo at all timepoints from week 1 (all P ≤ .01 and all P ≤ .05, respectively) and those receiving 4 mg baricitinib + TCS vs placebo + TCS at all timepoints from week 2 (all P ≤ .05 for both).

Study details: This post hoc analysis included 1316 patients with moderate-to-severe AD who received baricitinib (2 or 4 mg) or placebo in BREEZE-AD1/AD2 or baricitinib (2 or 4 mg)+TCS or placebo+TCS in BREEZE-AD7 for 16 weeks.

Key clinical point: Upadacitinib demonstrated an acceptable safety profile and led to significant and sustained improvements in disease signs and symptoms through 48 weeks of observation in patients with moderate-to-severe atopic dermatitis (AD) who were unresponsive to conventional treatments.

Major finding: At weeks 16 and 48, an Eczema Area and Severity Index-75 response was achieved by 78.2% and 87.6% of patients, respectively, with a significant reduction in mean sleeplessness, skin pain, and itch Numeric Rating Scale scores (all P < .001). Most adverse events were of mild-to-moderate severity.

Study details: This real-world prospective study included 146 adult patients with moderate-to-severe AD who were unresponsive, intolerant, or had contraindications to the approved therapies for moderate-to-severe AD and received 15 or 30 mg upadacitinib alone or combined with corticosteroids for 48 weeks.

Disclosures: This study did not receive any funding. Some authors, including the lead author, declared serving as investigators, speakers, advisory board members, or consultants for or receiving lecture or speaker honoraria, research grants, or personal fees from various sources.

Key clinical point: Dupilumab rapidly reduced the skin abundance of Staphylococcus aureus in patients with moderate-to-severe atopic dermatitis (AD), and the reduction correlated with improvements in all AD severity measurements except itch.

Major finding: At day 3, the dupilumab vs placebo group showed a 7.5-fold reduction (P = .02) in the skin abundance of S. aureus. A significant positive correlation was observed between the reduction in abundance and SCORing Atopic Dermatitis score with dupilumab (repeated measure correlation coefficient 0.39; P < .001), which was similar for other AD severity measurements except pruritus Numeric Rating Scale score.

Study details: Findings are from the multicenter, double-blind ADRN09 trial including 71 adult patients with moderate-to-severe AD who were randomly assigned to receive dupilumab (n = 45) or placebo (n = 26).
