Colorectal Cancer

A large study shows that middle-age men engaged in lots of cardiovascular exercise have a reduced risk of developing and dying from lung and colorectal cancer.

Adding the VEGF inhibitor axitinib to first-line treatment of FOLFOX-6 for metastatic colorectal cancer failed to improve progression-free and overall survival.

Women diagnosed with endometrial cancer at age 50 or younger had a fourfold increased risk for a subsequent colorectal cancer diagnosis, according to a historical cohort study published recently in the Journal of Clinical Oncology.

Patients with stage III colon cancer who have a history of smoking are more likely to have worse outcomes, according to a large, randomized phase III trial result.

Colorectal cancer patients testing positive for Lynch Syndrome on MSI and IHC were most likely to seek genetic counseling when contacted by a genetic counselor.

In a new study, researchers found that higher body mass index was associated with a risk of CTNNB1-negative colorectal cancer, while higher physical activity was associated with a lower risk for this type of disease.

An international group of researchers have collaborated on an unbiased genome-wide analysis of colorectal cancer, coming up with three distinct molecular subtypes that are potentially clinically relevant and are varying in their biology and clinical outcomes.

The same week that bevacizumab (Avastin) received a new indication for the treatment of metastatic colorectal cancer, results from two phase III trials involving the drug were presented at the American Society of Clinical Oncology 2013 Gastrointestinal Cancers Symposium (ASCO GI) held January 24–26 in San Francisco.

In this interview we discuss the latest treatments and research for gastrointestinal cancers with Dr. Cathy Eng, associate professor, department of gastrointestinal medical oncology, The University of Texas MD Anderson Cancer Center.

There has been a decline in overall cancer screening among the US population. Only colorectal cancer screening rates met current screening goals. Cancer survivors specifically met current national screening goals with the exception of cervical cancer screening.

Using a large genome-wide study of more than 28,000 individuals, three new genetic links to colorectal cancer have been identified, holding the potential for new therapeutic targets.

Initiating discussions about end-of-life care with patients with incurable cancers early in their disease was associated with a decrease in late-stage aggressive cancer treatments such as chemotherapy or acute care, and with an increase in the use of hospice care at the end of life.

Researchers have developed a relatively simple breath analysis testing volatile organic compounds that may one day be used as a way to screen for colorectal cancer.

Researchers have found a novel cellular mechanism that determines resistance to various targeted cancer therapies and several different cancers. The gene may be a key biomarker that could predict responses and provide better strategies to treat drug-resistant cancers.

Researchers have found a key pathway that is responsible for metastasis initiation of colorectal tumors to the liver-a frequent site for this tumor type to spread.

Colon cancer patients whose diet consists more of carbohydrates and foods that cause high blood-sugar levels had an increased risk of cancer recurrence and death, according to a new study.

According to a new study, daily aspirin helped colorectal cancer patients whose cancer has a mutated PIK3CA gene live longer.

Maintenance therapy with a new immunomodulator agent called MGN1703 improves progression-free survival over placebo in patients with metastatic colorectal cancer, according to a new study presented at the ESMO 2012 Congress.

The FDA has approved the multikinase inhibitor regorafenib (Stivarga) to treat patients with colorectal cancer that has metastasized following previous treatment.

To the Editor: We appreciated the commentaries by Drs. Duda, Glimelius, and Willet on our paper “Current Perspectives on Preoperative Integrated Treatments for Locally Advanced Rectal Cancer: A Review of Agreement and Controversies” (August issue of ONCOLOGY).

A new oral treatment is showing promise in relapsed, refractory colorectal cancer. Patients given TAS-102, an antitumor agent, showed improved survival and reduced risk of death compared to those given a placebo.

Researchers in Germany have found that longer-term follow-up would still lower risk of colorectal cancer development among patients who had an adenoma detected and removed.

In populations in whom there has been a focus on the important components of rectal cancer management, 5-year survival is better in rectal cancer than in colon cancer, which was not the case in the past. Total mesorectal excision (TME) is one of many important components of current management.

As we look forward, we suggest that the priority should be to further our understanding of the tumor’s interactions with its microenvironment and with the immune system. We think that such an understanding will be critical for advances in locally advanced rectal cancer therapy.

The preferred integrated treatment modality for locally advanced rectal cancer is preoperative radio(chemo)therapy followed by total mesorectal excision, though certain aspects of this standard are still debated.
