A pair of new studies offers more evidence for the value of vegetables and the risk of red meat on the cancer prevention front. Researchers report that high consumption of vegetables – especially lettuce, legumes, and cruciferous varieties – appears to lower the risk of liver cancer/liver disease. A separate team suggests that high consumption of red meat, organ meats, and processed meats boosts the risk of gastric cancer.

The findings of the latter study “reinforce the idea that avoidance of red meat and processed meat is probably good beyond [the prevention of] colorectal cancer,” said corresponding author and epidemiologist Paolo Boffetta, MD, MPH, of Stony Brook University Cancer Center, New York, in an interview. “The possible carcinogenic effect may extend beyond the colon.”

Both studies were released at the annual meeting of the American Association for Cancer Research.

For the red meat study, researchers examined statistics from the Golestan cohort study, which is prospectively tracking 50,045 people aged 40-75 from northeastern Iran. The study focuses on esophageal cancer due to the region’s high rate of the disease.

Red meat consumption is fairly rare in the region, where residents typically prefer chicken, said study lead author Giulia Collatuzzo, MD, a resident physician in occupational medicine at the University of Bologna, Italy, in an interview. On average, participants reported eating 18.4 grams daily of red meat and 72.1 grams daily of white meat.

The researchers tracked study participants for a median 12-year follow-up, during which 369 developed esophageal cancer and 368 developed gastric cancer. Red meat was only linked to more esophageal cancer in women (hazard ratio, 1.13, 95% confidence interval, 1.00-1.18, for each quintile increase in consumption).

Overall red meat consumption (including red meat, organ meat, and processed meat) was linked to higher rates of gastric cancer (HR, 1.08, 95% CI, 1.00-1.17) for each quartile increase in consumption, as was consumption of the red meat subtype alone (HR, 1.09, 95% CI, 1.00-1.18).

According to Dr. Collatuzzo, the findings suggest that those in the highest quartile of overall red meat consumption may have around a 25% increase in risk, compared with the lowest quartile.

Overall, she said, the study findings aren’t surprising. The lack of a connection between red meat consumption and esophageal cancer may be due to the fact that meat only temporarily transits through the esophagus, she said.

For the liver cancer/liver disease study, researchers examined the medical records of 470,653 subjects in the NIH-AARP Diet and Health Study. They were recruited in 1995-1996 when they were 50-71 years old. Over a median follow-up of 15.5 years, 899 developed liver cancer, and 934 died of chronic liver disease.

The median intakes of vegetables in quintile 5 (highest) and quintile 1 (lowest) were 3.7 cups daily and 1.0 cups daily, respectively, said study lead author Long-Gang Zhao, MS, a graduate student at Harvard University.

After adjusting for possible cofounders, those in the highest quintile of vegetable consumption were a third less likely to develop liver cancer, compared with the lowest quintile (HR, 0.66, 95% CI, 0.53-0.82, P < 0.01). Several types of vegetables appeared to be the strongest cancer fighters: cruciferous (broccoli, cauliflower), lettuce, legumes, and carrots. These kinds of vegetables were also linked to lower rates of chronic liver disease mortality (all P < 0.01), as was total vegetable intake for the top quintile versus the lowest quintile (HR, 0.60, 95% CI, 0.49-0.74, P = < 0.01).

“A one-cup increase (8 oz or 225 g) in vegetable intake was associated with about 20% decreased risk of liver cancer incidence and chronic liver mortality,” Zhao said.

There was no statistically significant link between fruit consumption and liver cancer or chronic liver disease mortality.

The findings provide more insight into diet and liver disease, Zhao said. “Chronic liver disease, which predisposes to liver cancer, is the tenth cause of death worldwide, causing two million deaths each year. It shares some etiological processes with liver cancer. Therefore, examining both chronic liver disease mortality and liver cancer incidence in our study may provide a more general picture for the prevention of liver diseases.”

As for limitations, both studies are based on self-reports about food consumption, which can be unreliable, and the subjects in the fruit/vegetable analysis were mainly of European origin.

The authors of both studies report no relevant disclosures. No funding is reported for either study.

In patients with B-cell deficiencies, CoVac-1, a SARS-CoV-2 vaccine currently in clinical trials in Germany, induced T-cell immune responses in a large proportion of patients, according to study results presented at the annual meeting of the American Association for Cancer Research.

The phase 1/2 trial included 54 patients with a B-cell deficiency (mean age, 63 years; 28% female): 4 had congenital B-cell deficiency and 50 had a blood cancer (lymphocytic leukemia or lymphoma). T-cell immune responses were observed in 86% of patients 28 days after vaccination with a single CoVac-1 dose. The potency of CoVac-1–induced T-cell responses exceeded those seen typically with B cell–deficient patient responses after mRNA vaccine treatment and were comparable with those seen among nonimmunocompromised COVID-19 patients.

In the majority of individuals, currently approved SARS-CoV-2 vaccines induce a robust immune response, however, their efficacy, has been shown to be decreased among individuals who are immunocompromised. Patients treated for hematologic cancers, in particular, receive treatment regimens that damage healthy immune cells, particularly B cells, said Juliane Walz, MD, the study’s senior author and professor of medicine at University Hospital Tübingen (Germany).

“In the clinic, we see many cancer patients who do not mount sufficient humoral immune responses after vaccination with available SARS-CoV-2 vaccines,” Dr. Walz said. “These patients are at a high risk for a severe course of COVID-19.”

B-cell deficiency, she stated, can be compensated for by enhancing T-cell responses against SARS-CoV-2, which can then combat infections in the absence of neutralizing antibodies.

In a prior study of CoVac-1 among 36 adults without immune deficiency, the vaccine elicited T-cell responses that were still robust 3 months post vaccination, and that included responses against omicron and other key SARS-CoV-2 variants.

While mRNA-based or adenoviral vector-based vaccines are limited to the spike protein and are thus prone to loss of activity because of viral mutations, CoVac-1–induced T-cell immunity is far more intense and broader, Dr. Walz said.

CoVac-1 is a peptide vaccine that is injected directly rather than being encoded via mRNA and targets different viral components. It would not be given, however, to healthy, immunocompetent adults because it is important for them to have both B-cell antibody and T-cell response.

The patients with B-cell deficiency recruited for the study were given a single dose of CoVac-1 and assessed for safety and immunogenicity until day 56. Prior vaccinations with an approved SARS-CoV-2 vaccine had failed to elicit a humoral response in 87% of the subjects.

“Our vaccine does not induce antibody responses,” Dr. Walz said. “However, it could be used to induce broad T-cell responses as a complementary or additive vaccine for elderly adults. In the elderly, antibody responses decline very, very fast after vaccination.”

Dr. Walz said that CoVac-1 could find application in various syndromes associated with congenital B-cell deficiencies, in autoimmune diseases such as rheumatoid arthritis and multiple sclerosis, or diseases treated with rituximab or other B cell–depleting therapies (for example, ofatumumab, blinatumomab, or chimeric antigen receptor T cells), and in transplant patients.

A phase 3 study of CoVac-1 versus placebo is under discussion and would require about 300-500 subjects, Dr. Walz said.

“CoVac-1 is designed to induce broad and long-lasting SARS-CoV-2 T-cell immunity, even in individuals who have impaired ability to mount sufficient immunity from a currently approved vaccine, and thus protect these high-risk patients from a severe course of COVID-19,” Dr. Walz said.

“Having an option for these patients is just critical – so this is significant work,” said Ana Maria Lopez, MD, MPH, of the Sidney Kimmel Cancer Center–Jefferson Health, Philadelphia.

Limitations of this study included the small sample size with low racial and ethnic diversity, Dr. Walz stated.

Funding was provided by the Ministry of Science, Research and the Arts of the state of Baden-Württemberg; the Federal Ministry of Research and Education in Germany; the German Research Foundation under Germany’s Excellence Strategy; and the Clinical Cooperation Unit Translational Immunology at University Hospital Tübingen. Dr. Walz holds the CoVac-1 patent.

With New York nurse practitioners recently gaining full practice authority (FPA), half of the country’s NPs now have the ability to provide patients with easier access to care, according to leading national nurse organizations.

New York joins 24 other states, the District of Columbia, and two U.S. territories that have adopted FPA legislation, as reported by the American Association of Nurse Practitioners (AANP). Like other states, New York has been under an emergency order during the pandemic that allowed NPs to practice to their full authority because of staffing shortages. That order was extended multiple times and was expected to expire this month, AANP reports.

“This has been in the making for nurse practitioners in New York since 2014, trying to get full practice authority,” Michelle Jones, RN, MSN, ANP-C, director at large for the New York State Nurses Association, said in an interview.

NPs who were allowed to practice independently during the pandemic campaigned for that provision to become permanent once the emergency order expired, she said. Ms. Jones explained that the FPA law expands the scope of practice and “removes unnecessary barriers,” namely an agreement with doctors to oversee NPs’ actions.

FPA gives NPs the authority to evaluate patients; diagnose, order, and interpret diagnostic tests; and initiate and manage treatments – including prescribing medications – without oversight by a doctor or state medical board, according to AANP.

Before the pandemic, New York NPs had “reduced” practice authority with those who had more than 3,600 hours of experience required to maintain a collaborative practice agreement with doctors and those with less experience maintaining a written agreement. The change gives full practice authority to those with more than 3,600 hours of experience, Stephen A. Ferrara, DNP, FNP-BC, AANP regional director, said in an interview.

Ferrara, who practices in New York, said the state is the largest to change to FPA. He said the state and others that have moved to FPA have determined that there “has been no lapse in quality care” during the emergency order period and that the regulatory barriers kept NPs from providing access to care.

Jones said that the law also will allow NPs to open private practices and serve underserved patients in areas that lack access to health care. “This is a step to improve access to health care and health equity of the New York population.”

It’s been a while since another state passed FPA legislation, Massachusetts in January 2021 and Delaware in August 2021, according to AANP.

Earlier this month, AANP released new data showing a 9% increase in NPs licensed to practice in the United States, rising from 325,000 in May 2021 to 355,000.

The New York legislation “will help New York attract and retain nurse practitioners and provide New Yorkers better access to quality care,” AANP President April Kapu, DNP, APRN, said in a statement.

It’s been a while since another state passed FPA legislation, Massachusetts in January 2021 and Delaware in August 2021, according to AANP.

Earlier this month, AANP released new data showing a 9% increase in NPs licensed to practice in the United States, rising from 325,000 in May 2021 to 355,000.

The New York legislation “will help New York attract and retain nurse practitioners and provide New Yorkers better access to quality care,” AANP President April Kapu, DNP, APRN, said in a statement.

A simple, two-ingredient gel may boost the fighting power of a groundbreaking cancer treatment, say Stanford University engineers.

The gel – made from water and a plant-based polymer – delivers targeted T cells adjacent to a cancer growth, taking aim at solid tumors.

It’s the latest development in CAR T-cell therapy, a type of immunotherapy that involves collecting the patient’s T cells, reengineering them to be stronger, and returning them to the patient’s body.

Results have been promising in blood cancers, such as leukemia and lymphoma, but less so in solid tumors, such as brain, breast, or kidney cancer, according to the National Cancer Institute.

The gel “is a really exciting step forward,” says Abigail Grosskopf, a PhD candidate at Stanford (Calif.) University, who is the lead study author, “because it can change the delivery of these cells and expand this kind of treatment to other cancers.”
 

CAR T-cell therapy: Limits in solid tumors

Currently available CAR T-cell therapies are administered by intravenous infusion. But that doesn’t do much against tumors in specific locations because the cells enter the bloodstream and flow throughout the body. The cancer-fighting effort exhausts the T cells, weakening their ability to infiltrate dense tumors.

CAR T cells need cytokines to tell them when to attack, Ms. Grosskopf explains. If delivered through an IV drip, the number of cytokines required to destroy a solid tumor would be toxic to other, healthy parts of the body.

So Ms. Grosskopf and her colleagues created a hydrogel that can temporarily hold the T cells and cytokines and that can be injected near a tumor, bombarding the cancerous growth.

In their study, which was published in Science Advances, the injections wiped out mouse tumors in 12 days. The gel degraded harmlessly a few weeks later.
 

A “leaky pen” that fights cancer

The reason a gel works better than a liquid is because of its staying power, says Ms. Grosskopf, who compares the method to a leaky pen.

The gel acts as the “pen,” releasing activated CAR T cells at regular intervals to attack the cancerous growth. Whereas liquid dissipates quickly, the gel’s structure is strong enough to stay in place for weeks, Ms. Grosskopf says. Plus, it’s biocompatible and harmless within the body, she adds.

More preclinical studies are needed before human clinical trials can occur, Ms. Grosskopf says.

“Not only could this be a way to deliver T cells and cytokines,” Ms. Grosskopf says, “but it may be used for other targeted therapy cancer drugs that are in development. So we see this as running parallel to those efforts.”

Taking an even broader view, the gel could have applications across medical specialties, such as slow-release delivery of vaccines.

New research suggests that chemotherapy treatments for recurrent high-grade gliomas indicated by an assay-guided tool called ChemoID can boost median survival, compared with physician choice.

The randomized, phase 3 trial results were presented at the annual meeting of the American Association for Cancer Research.

Over a median follow-up of 9 months, median overall survival in the ChemoID group was 12.5 months (95% confidence interval, 10.2-14.7), compared with 9 months (95% CI, 4.2-13.8) in the group whose treatments were chosen by physicians (P = .010).

“While the prognosis is very dismal, we’re still providing a 3.5-month benefit in the guided arm versus physician choice,” said study coauthor Jagan Valluri, PhD, professor of cellular biology and integrative medicine at Marshall University, Huntington, W. Va.

As Dr. Valluri noted, patients with recurrent high-grade gliomas typically have failed radiation and are left with poor prognoses. Fewer than one in four patients respond to chemotherapy at this point, he said, and the response is inconsistent from patient to patient.

“We developed ChemoID since cancer is very unique,” he said, “and any kind of chemotherapy should be tailored to each individual patient on a case-by-case basis.”

The ChemoID tool, a proprietary assay, tests the response of patient cells to various chemotherapy treatments. A test costs $3,500, and some insurers cover it, Dr. Valluri said.

For the new study, researchers randomly assigned 50 patients with grade III/IV recurrent glioma to be treated with chemotherapy chosen by physicians or chemotherapy recommended by the ChemoID tool.

Risk of death in the ChemoID group was lower than in the physician-guided group (hazard ratio, 0.44; 95% CI, 0.24-0.81; P = .008), and median progression-free survival was higher in the ChemoID group (10.1 months vs. 3.5 months; 95% CI, 4.8-15.4 vs. 1.9-5.1; HR, 0.25; 95% CI, 0.14-0.44; P < .001).

“We want the treating physician to have actionable tools in front of them before they treat the patient,” Dr. Valluri said. “We want this assay to become mainstream and part of the standard care workup.”

The study is funded by Cordgenics, where Dr. Valluri serves as chief operating officer.

Clinicians are not following guidelines that recommend a de-escalation in surveillance for patients with low-risk non–muscle-invasive bladder cancer (NMIBC), a new study concludes.  

These cancers are associated with low rates of recurrence, progression, and bladder cancer–specific death, so current clinical practice guidelines recommend against frequent monitoring and testing.

However, the study authors found that patients with a low grade Ta NMIBC diagnosis underwent a median of three cystoscopies per year, and many also received a median of two imagine scans (CT or MRI) as well as 2-3 urine-based tests.

“These data suggest a need for ongoing efforts to limit overuse of treatment and surveillance, which may in turn mitigate associated increases in the costs of care,” write the authors, led by Kelly K. Bree, MD, from the department of urology, University of Texas MD Anderson Cancer Center, Houston. Bladder cancer has the highest lifetime treatment cost of all malignancies, they point out.

The study was published online in JAMA Network Open.
 

Higher value and more evidence-based

The impact of increased surveillance of this patient cohort has broad implications for patients and the health care system in general, say experts writing in an accompanying editorial.

“It has been well established that workup for NMIBC can have negative consequences for the physical and psychological health of patients,” note Grayden S. Cook, BS, and Jeffrey M. Howard, MD, PhD, both from University of Texas Southwestern Medical Center, Dallas.

“Many of these patients undergo frequent CT imaging of the urinary tract, which carries a high dose of radiation as well as the potential for financial toxic effects (that is, detrimental consequences to the patient because of health care costs),” they write.

Additionally, patient distress is a factor, as they may experience preprocedural anxiety, physical discomfort during procedures, and worry about disease progression, they point out.

“The impact of these patterns is substantial and may have negative consequences for both patients and the health care system,” they conclude. “Thus, it is imperative to move forward with initiatives that provide higher value and are more evidence-based and patient-centered.”
 

Study finds frequent surveillance

The American Urological Association (AUA)/Society of Urologic Oncologists (SUO), the European Association of Urology, and the International Bladder Cancer Group have made an effort to de-escalate surveillance and treatment for patients with low-grade Ta disease, while at the same time maintaining appropriate surveillance for high-grade aggressive disease.

However, the new study found that in practice, such patients undergo frequent testing.

The study involved 13,054 patients with low-grade Ta NMIBC. Most of the participants were male (73.5%), with a median age of 76 years, and had no or few comorbidities (71.2%).

Most patients had undergone cystoscopy, and rates increased over time: from 79.3% of patients in 2004 to 81.5% of patients in 2013 (P = .007). Patients underwent a median of 3.0 cystoscopies per year following their diagnosis, and upper-tract imaging was performed in most patients.

The use of kidney ultrasonography also rose from 19% of patients in 2004 to 23.2% in 2013, as did retrograde pyelography (20.9% in 2004 vs. 24.2% in 2013). Conversely, the use of intravenous pyelography declined (from 14.5% in 2004 to 1.7% in 2012), but there was an increase in CT and MRI in all years except 2010 (from 30.4% of patients in 2004 to 47% of patients in 2013; P < .001). The rate of urine-based testing also significantly increased during the study period (from 44.8% in 2004 to 54.9% in 2013; P < .001), with patients undergoing between two to three tests per year.

Adherence to current guidelines remained similar during the study time frame. For example, 55.2% of patients received two cystoscopies per year in 2004-2008, compared with 53.8% in 2009-2013 (P = .11), suggesting that there was an overuse of all surveillance testing modalities.

As for treatment, 17.2% received intravesical immunotherapy with bacillus Calmette-Guérin, 6.1% were treated with intravesical chemotherapy (excluding receipt of a single perioperative dose). Disease recurrence within this cohort was 1.7%, and only 0.4% experienced disease progression.

When looking at the cost, the total median expenditures at 1 year after diagnosis increased by 60% during the study period, from $34,792 in 2004 to $53,986 in 2013. Higher costs were seen among patients who experienced a recurrence versus no recurrence ($76,669 vs. $53,909).

The study was supported by a grant from the U.S. Department of Defense Peer Reviewed Cancer Research Program. Several of the authors have disclosed relationships with industry, as noted in the original article. Editorialists Mr. Cook and Dr. Howard have disclosed no relevant financial relationships.

It may seem like déjà vu, as not much has changed regarding the rankings of top U.S. medical schools over the past 2 years.

The University of Washington, Seattle retained its ranking from the U.S. News & World Report as the top medical school for primary care for 2023. Also repeating its 2022 standing as the top medical school for research is Harvard University. Both schools ranked in the top 10 for primary care and research, with Harvard also ranking in the top spot for half of eight specialties reported.

In the primary care ranking, the top 10 schools after the University of Washington were the University of California, San Francisco; the University of Minnesota; Oregon Health and Science University; the University of North Carolina at Chapel Hill; the University of Colorado; the University of Nebraska Medical Center; the University of California, Davis; and Harvard. Three schools tied for the no. 10 slot: the University of Kansas Medical Center, the University of Massachusetts Chan Medical Center, and the University of Pittsburgh.

The top five schools with the most graduates practicing in primary care specialties are Des Moines University, Iowa (50.6%); the University of Pikeville (Ky.) (46.8%); Western University of Health Sciences, Pomona, California (46%); William Carey University College of Osteopathic Medicine, Hattiesburg, Mississippi (44.7%); and A.T. Still University of Health Sciences, Kirksville, Missouri (44.3%).
 

Best for research

When it comes to schools ranking the highest for research, the Grossman School of Medicine at New York University takes the no. 2 spot after Harvard. Three schools were tied for the no. 3 spot: Columbia University, Johns Hopkins University, and the University of California, San Francisco; and two schools for no. 6: Duke University and the Perelman School of Medicine at the University of Pennsylvania, Philadelphia. No. 8 goes to Stanford University, followed by the University of Washington. Rounding out the top 10 is Yale University.

Specialty ranks

The top-ranked schools in eight specialties are as follows:

• Anesthesiology: Harvard
• Family medicine: the University of Washington
• Internal medicine: Johns Hopkins
• Obstetrics/gynecology: Harvard
• Pediatrics: the University of Pennsylvania (Perelman)
• Psychiatry: Harvard
• Radiology: Johns Hopkins
• Surgery: Harvard

Metformin use, regardless of dose, was associated with increased overall survival in older adults with advanced cancer, according to results of a retrospective study of patients with type 2 diabetes and stage IV cancer.

The analysis included 7,725 patients with lung, breast, colorectal, prostate, or pancreatic cancer identified through a search of a Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset from 2007 to 2016.

Out of the full dataset, 2,981 patients (38.5%) had been prescribed metformin, and use was highest among patients with prostate cancer (46%).

Patients who took metformin versus those who did not had significantly better overall survival in both unadjusted (unadjusted hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.69-0.76; P < .001) and adjusted models (adjusted HR, 0.77; 95% CI, 0.73-0.81; P < .001).

Lead author Lisa Scarton, PhD, RN, assistant professor, University of Florida College of Nursing, Gainesville, said that the “underlying mechanisms of metformin related to cancer are still not completely understood,” but many studies have shown metformin is associated with a reduction in the incidence of cancer, a reduction in cancer mortality, and an improvement in overall survival.

“As more evidence of anticancer benefit of metformin is emerging, it is important to explore optimal dosages that significantly improve cancer outcomes to boost anticancer effect,” she said in an interview.  

Dr. Scarton presented the new data in a poster at the annual meeting of the American Association for Cancer Research.  

The analysis found no significant difference in overall survival between patients who took metformin with average daily doses ≥ 1,000 mg or < 1,000 mg (aHR, 1.00; 95% CI, 0.93-1.08; P = .90).

Although the improvement in overall survival was seen in cancer subgroups, regardless of dose, Dr. Scarton noted the benefit was greatest among patients with breast cancer (aHR, 0.67; 95% CI, 0.56-0.82; P < .001). Hazard ratios among those who received metformin were 0.78 (95% CI, 0.69-0.88; P < .001) for colorectal cancer, 0.77 (95% CI, 0.72-0.82; P < .001) for lung cancer, 0.82 (95% CI, 0.72-0.93; P < .001) for pancreatic cancer, and 0.74 (95% CI, 0.62-0.88; P = .002) for prostate cancer. Also, she noted that race/ethnicity did not play a role as a significant factor for predicting better overall survival.

Among study limitations, Dr. Scarton said, was the advanced age of patients. “Our study population was 66 and older. It would be interesting to investigate this relationship among younger adults. We would also explore explicit benefits of metformin use in different racial and ethnic groups.”

The study was funded by the University of Florida. Dr. Scarton has reported no relevant financial relationships.

Globally, diagnoses and deaths from colorectal cancer (CRC) more than doubled over the past 30 years, according to a new analysis of 204 countries.

However, trends in CRC incidence and deaths varied by age, region, and sex. Investigators expressed particular concern over the rising incidence rates among people younger than 50 and those living in low and middle sociodemographic index countries in Asia and Africa.

“These results provide comprehensive and comparable estimates that can inform efforts for equitable colorectal cancer control worldwide,” the authors write. However, “further research is required to understand the causes of the colorectal cancer burden in younger adults (aged less than 50 years) and the main risk factors, including obesity, physical inactivity, alcohol consumption, smoking, and an altered gut microbiome, that might have led to the rise in the colorectal cancer burden.”

The study was published online in the Lancet Gastroenterology and Hepatology.

CRC is the third leading cause of cancer deaths worldwide, but data on incidence and mortality by location, age, and sex remain less clear.

In the current Global Burden of Diseases, Injuries and Risk Factors Study, researchers evaluated age, sex, and geography-level estimates of CRC incidence, deaths, and disability-adjusted life-years (DALYs) from 204 countries between 1990 and 2019.

The authors found that cases of CRC increased by almost 2.6-fold over the 30-year study period, from 842,098 to 2.17 million. Deaths from CRC increased at a similar but slightly lower rate – rising 2.1-fold over the same period, from 518,126 to 1.09 million. DALYs also nearly doubled, going from 12.4 million in 1990 to 24.3 million in 2019.

In addition, the global age-standardized incidence rate increased from 22.2 to 26.7 per 100,000.

Overall, the age-standardized mortality rate decreased slightly, from 14.3 to 13.7 per 100,000; however, only high-middle and high sociodemographic index regions experienced a decrease; low and middle sociodemographic index regions experienced an increase. The age-standardized DALY rate also declined overall, from 308.5 per 100,000 in 1900 to 295.5 per 100,000 in 2019.

The authors further broke down CRC incidence and deaths by age, region, and sex.

Over the study period, males demonstrated greater increases in CRC incidence, deaths, and DALYs, compared with females. In 2019, the age-standardized CRC incidence rate was 1.5 times higher in males (33.1 vs 21.2 per 100,000), as was the age-standardized mortality rate (16.6 vs. 11.2 per 100,000). The age-standardized DALY rate showed a similar trend by sex – 360 versus 238 per 100,000 in males versus females.

Trends varied by age as well. CRC incidence rates increased the most in people aged 85 and older, followed by those between 20 and 49 years, while rates decreased for those between 50 and 80 years in high sociodemographic index countries.

Geography mattered too. China, the United States, and Japan demonstrated the highest number of new CRC cases across all ages and for both sexes in 2019 – 607,900 in China, 227,242 in the United States, and 160,211 in Japan.

In terms of mortality, China, the United States, and India had the highest CRC death counts: 261,777 in China, 84,026 in the United States, and 79,098 in India.

When it comes to age-standardized incidence rates, Taiwan, Monaco, and Andorra were at the top: Taiwan with 62 per 100,000 cases, Monaco with 60.7 per 100,000, and Andorra with 56.6 per 100,000.

On the other hand, Somalia, Niger, and Bangladesh had the lowest age-standardized incidence rates, 5 per 100,000 in Somalia and 5.6 per 100,000 in Niger and Bangladesh.

The highest age-standardized mortality rates occurred in Greenland, Brunei, and Hungary: 31.4 per 100,000 in Greenland, 30.3 per 100,000 in Brunei, and 28.6 per 100,000 in Hungary.

The relative contribution of different risk factors also varied by region. For example, in sub-Saharan Africa and lower-income countries in Asia, diets low in calcium and milk were the main CRC risk factors. In contrast, smoking and alcohol consumption were the main risk factors driving CRC in high-income regions.

Still, the reasons underlying some of these trends – such as the increasing incidence of CRC in patients under the age of 50 – remain uncertain. One possible explanation for this trend, the researchers point out, is the birth cohort effect, which suggests that those born in the second half of the 20th century are increasingly exposed to potentially modifiable risk factors, such as an unhealthy diet, obesity, and sedentary lifestyles.

Overall, the authors note that the data generated in this study provide an important resource for both patients and oncologists about current trends in incidence and mortality and where gaps in preventive measures may exist.

In particular, the authors conclude that “public health interventions for colorectal cancer awareness, screening, and prevention through containment of modifiable risk factors such as alcohol, smoking, unhealthy diet ... and obesity are key to stemming the tide of colorectal cancer worldwide.”

The study was funded by the Bill & Melinda Gates Foundation. The authors have disclosed no relevant financial relationships.

Over the study period, males demonstrated greater increases in CRC incidence, deaths, and DALYs, compared with females. In 2019, the age-standardized CRC incidence rate was 1.5 times higher in males (33.1 vs 21.2 per 100,000), as was the age-standardized mortality rate (16.6 vs. 11.2 per 100,000). The age-standardized DALY rate showed a similar trend by sex – 360 versus 238 per 100,000 in males versus females.

Trends varied by age as well. CRC incidence rates increased the most in people aged 85 and older, followed by those between 20 and 49 years, while rates decreased for those between 50 and 80 years in high sociodemographic index countries.

Geography mattered too. China, the United States, and Japan demonstrated the highest number of new CRC cases across all ages and for both sexes in 2019 – 607,900 in China, 227,242 in the United States, and 160,211 in Japan.

In terms of mortality, China, the United States, and India had the highest CRC death counts: 261,777 in China, 84,026 in the United States, and 79,098 in India.

When it comes to age-standardized incidence rates, Taiwan, Monaco, and Andorra were at the top: Taiwan with 62 per 100,000 cases, Monaco with 60.7 per 100,000, and Andorra with 56.6 per 100,000.

On the other hand, Somalia, Niger, and Bangladesh had the lowest age-standardized incidence rates, 5 per 100,000 in Somalia and 5.6 per 100,000 in Niger and Bangladesh.

The highest age-standardized mortality rates occurred in Greenland, Brunei, and Hungary: 31.4 per 100,000 in Greenland, 30.3 per 100,000 in Brunei, and 28.6 per 100,000 in Hungary.

The relative contribution of different risk factors also varied by region. For example, in sub-Saharan Africa and lower-income countries in Asia, diets low in calcium and milk were the main CRC risk factors. In contrast, smoking and alcohol consumption were the main risk factors driving CRC in high-income regions.

Still, the reasons underlying some of these trends – such as the increasing incidence of CRC in patients under the age of 50 – remain uncertain. One possible explanation for this trend, the researchers point out, is the birth cohort effect, which suggests that those born in the second half of the 20th century are increasingly exposed to potentially modifiable risk factors, such as an unhealthy diet, obesity, and sedentary lifestyles.

Overall, the authors note that the data generated in this study provide an important resource for both patients and oncologists about current trends in incidence and mortality and where gaps in preventive measures may exist.

In particular, the authors conclude that “public health interventions for colorectal cancer awareness, screening, and prevention through containment of modifiable risk factors such as alcohol, smoking, unhealthy diet ... and obesity are key to stemming the tide of colorectal cancer worldwide.”

Vaccinated patients with cancer are more likely than those without cancer to contract a breakthrough COVID-19 infection, which puts them at a much higher risk for hospitalization and death, according to a study published in JAMA Oncology.

The risks were highest among patients who had certain cancers and those who had received cancer treatment within the past year.

“These results emphasize the need for patients with cancer to maintain mitigation practice, especially with the emergence of different virus variants and the waning immunity of vaccines,” the study authors wrote.

Researchers at Case Western Reserve University in Cleveland analyzed electronic health record data for more than 636,000 vaccinated patients, including more than 45,000 vaccinated patients with cancer. They looked for the time trends, risks, and outcomes of breakthrough COVID-19 infections for vaccinated cancer patients in the United States between December 2020 and November 2021.

Overall, the cumulative risk of breakthrough infections in vaccinated cancer patients was 13.6%, with the highest risk for pancreatic (24.7%), liver (22.8%), lung (20.4%), and colorectal (17.5%) cancers and the lowest risk for thyroid (10.3%), endometrial (11.9%), and breast (11.9%) cancers, versus 4.9% in vaccinated patients without cancer.

Patients who had medical encounters for their cancer within the past year had a higher risk for a breakthrough infection, particularly those with breast cancer, blood cancers, colorectal cancer, bladder cancer, and pancreatic cancer.

Among patients with cancer, the overall risk for hospitalization after a breakthrough infection was 31.6%, as compared with 3.9% in those without a breakthrough infection. In addition, the risk of death was 6.7% after a breakthrough infection, as compared with 1.3% in those without a breakthrough infection.

Among patients who didn’t have cancer, the overall hospitalization risk was 25.9% in patients with a breakthrough infection, as compared with 3% in those without a breakthrough infection. The overall risk of death was 2.7% after a breakthrough infection, as compared with 0.5% in those without a breakthrough infection.

In addition, breakthrough infections continuously increased for all patients from December 2020 to November 2021, with the numbers consistently higher among patients with cancer.

“This increasing time trend may reflect waning immunity of vaccines, the emergence of different virus variants, and varied measures taken by individuals and communities over time during the pandemic,” the study authors wrote.

Vaccines are likely less protective against coronavirus infection in cancer patients, and in turn, cancer patients may be more susceptible to COVID-19 infections, the researchers wrote. As breakthrough infections continue to increase for everyone, patients with cancer will face increased risks for severe breakthroughs, hospitalization, and death, they concluded.
