Colorectal Cancer

Colorectal Cancer is cancer that develops in the colon (the longest part of the large intestine) and/or the rectum (the last several inches of the large intestine before the anus). In the United States, it is the fourth most common cancer in men and women. Caught early, it is often curable.

FDA clears trial of dual-targeted CAR T-cell therapy for cancer

The U.S. Food and Drug Administration this week granted permission for investigators at the University of Colorado Anschutz to conduct a clinical trial testing genetically engineered immune cells in adults with advanced colorectal cancer and pediatric patients with solid cancers who have exhausted standard treatment options.

Coffee after colorectal cancer? Decaf and caffeine show different links with mortality

In a prospective analysis of 1,098 people with colorectal cancer, researchers found no significant association between total or caffeinated coffee intake and all-cause or colorectal cancer-specific mortality in the cohort overall. Decaffeinated coffee was associated with lower all-cause mortality, while the highest quartile of caffeine intake was associated with lower all-cause and colorectal cancer-specific mortality, although the observational study cannot establish causation.

New AI tool automates colonoscopy quality assessment at scale

Colonoscopies are one of the most effective ways to prevent colorectal cancer, which is surging among young adults in the U.S. Yet, the quality of each procedure can vary substantially from one physician to another.

Helicobacter pylori exposure linked to one in five cases of bowel cancer

Exposure to the stomach microbe Helicobacter pylori may be associated with more than 1 in 5 cases of bowel cancer worldwide, suggests an exploratory risk attribution study, published in the open access journal eGastroenterology.

Microscopic peptide droplets reduce colorectal tumor growth in mice

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed microscopic peptide droplets that deliver large amounts of gene-silencing molecules into cancer and immune cells, reducing the growth of hard-to-treat colorectal tumours by about 67 per cent in mice.

IBD patients with family cancer history more likely to develop colorectal cancer

People with inflammatory bowel disease (IBD) who have several close relatives with colorectal cancer are significantly more likely to develop the disease themselves.

Alcohol-linked cancer deaths doubled over three decades in America

Alcohol-attributable cancer deaths in the U.S. doubled between 1990 and 2023, a new study found. The study also revealed that alcohol-linked cancer deaths are not limited to older adults or liver cancer.

Early-onset bowel cancer shows distinct biological and clinical features

One of Australia's largest real world studies of younger adults with advanced bowel cancer has identified important differences between cancers diagnosed before and after the age of 50, which could help doctors tailor treatments for younger adults more effectively.

Biosimilars reduce financial burden for cancer patients and insurers

Biologic drugs play an important role in treating cancers such as breast cancer and lymphoma, but their high costs can add to the financial burden of cancer care.

New study tracks global colorectal cancer risk across 185 nations

Colorectal cancer has long been recognized as a major global health threat, but its burden is far from evenly distributed. Incidence and mortality rates vary dramatically across countries, and these differences are closely tied to socioeconomic development, dietary transitions, and the adoption of screening programs.

Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.

New discovery helps identify colorectal cancer patients at risk for metastasis

Researchers from the University of Turku in Finland and Gustave Roussy Institute in France have discovered a molecular mechanism that regulates whether the cells of an aggressive colorectal cancer are conventional or inverted when they spread in the body.

Study maps rising lifetime risk of digestive cancers in China

The global landscape of oncology is shifting, and nowhere is this transition more complex or consequential than in China.

A striking immune cell pattern emerges around a person’s 100th birthday

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

Active screening cuts colorectal cancer death risk drastically

People who take part in screening for colorectal cancer may have as much as 43 per cent lower risk of dying from the disease, according to new estimates published in JAMA Network Open by researchers at Karolinska Institutet and Umeå University in Sweden.

Colorectal tumors may damage nerves before chemotherapy

Researchers at The University of Texas MD Anderson Cancer Center found that, in preclinical models of colorectal cancer, tumors can start damaging peripheral nerves before chemotherapy begins.

A decades-long study raises questions about sugary drinks and stomach cancer

A large prospective U.S. study followed more than 111,000 adults to examine whether sugar-sweetened and artificially sweetened beverage intake was associated with gastric cancer incidence. Researchers identified 278 gastric cancer cases over 3.2 million person-years and found that associations differed according to beverage type and level of consumption.
