Researchers have discovered a new way to fight colorectal cancer by targeting the 'skeletons' of cancer cells, which enable them to reproduce and spread. High-dose PPARgamma inhibitors destroy cancer cell microtubules, reducing their ability to grow and metastasize.
Recent research suggests that regular statin use is not linked to lower colorectal cancer risk, while folate intake does not appear to impact breast cancer risk. However, monitoring of thyroid function may be necessary for patients taking the medication sunitinib, which can cause fatigue and hypothyroidism.
A new study reveals that health-care delivery, particularly screening tests and surgical treatment, contribute to poorer outcomes for African-American patients with colorectal cancer. The study found that African-Americans were more likely to have advanced disease and received less surgical treatment compared to other ethnicities.

Researchers developed a vaccine that stimulates colorectal cancer patients' immune systems to fight cancerous cells, with 70% of patients producing TNF-alpha and GM-CSF in response. The vaccine works by generating infection-fighting white blood cells called T cells, which destroy cancer cells.
A new set of quality indicators has been created to evaluate the quality of care received by patients undergoing colorectal cancer surgery. The guidelines cover aspects of surgical care, including pre-operative evaluation and post-operative management, to provide a valuable tool for improving patient outcomes.

The study suggests tailoring individualized screening programs based on tobacco and alcohol consumption.
Scientists discover that vitamin D can regulate an oncogenic protein called beta-catenin, which is involved in colon cancer development. A drug mimic of vitamin D could potentially prevent some cancers at early stages, but may not be effective for late-stage cancers.
A research group identified 679 genes differently expressed in responders to chemotherapy compared to non-responders. RT-PCR analysis validated the findings, confirming the differential expression of 22 genes. The study suggests integrating molecular networks could improve diagnosis and treatment of colorectal cancer.
Regular screening significantly reduces cancer deaths in families with hereditary Lynch syndrome, with a 70% decrease in mortality rates. Additionally, research finds that people with IBD-related CRC have similar prognoses as the general population, while a self-propelling colonoscope shows promise in efficient and safe detection.
The APC tumor suppressor has a novel function in regulating Wnt signaling in the nucleus. In this new study, researchers demonstrate that APC opposes beta-catenin activity directly at Wnt target genes. The findings suggest that full-length APC protein is necessary to repress c-Myc gene expression and prevent colon cancer progression.
Researchers found that hepatic arterial infusion (HAI) therapy extended survival and improved quality of life in patients with colorectal cancer that has spread to the liver. HAI therapy resulted in a median survival of 24 months, better response rates, and longer time to disease progression compared to systemic chemotherapy.
The study found a small but significant increase in hip bone density among women taking calcium combined with vitamin D. However, the supplements had no detectable effect on colorectal cancer incidence or spine fractures.
Researchers found a 12% reduction in hip fractures among women taking supplements, but only those who adhered to the full dosage saw benefits. Women over 50 should prioritize dietary sources of calcium and Vitamin D for bone health.

A study of nearly 49,000 postmenopausal women found a modest reduction in breast cancer incidence among those with high fat intake, but this benefit was not seen in those who reduced their fat intake. Women should focus on reducing saturated and trans fats, increasing vegetable consumption, and maintaining regular exercise for overall ...
Researchers tracked over 8 years and found no reduction in colorectal cancer cases with low-fat diet intervention. The study suggests that mid-to-late life dietary changes may not significantly impact colorectal cancer risk.

A study on postmenopausal women found sex hormone levels to be not associated with breast cancer risk, while another study suggested that BRCA2 mutation carriers had a fourfold increased i...
Researchers propose a simple test that identifies more accurately individuals who might have colorectal cancer when used alongside traditional guaiac tests. This new approach could decrease the number of false positives in screening programs and reduce the need for colonoscopy, potentially leading to improved accuracy and reduced costs.
A large study of over 4000 participants found no association between statin use and reduced risk of colorectal cancer. The researchers noted that if statins strongly reduced the risk, any cholesterol-lowering drug would likely show some reduction in risk due to shared users.
Researchers found L1 in large quantities exclusively in aggressive colon cancer cells, enabling them to invade and metastasize more effectively. The discovery may have important implications for diagnosing colon cancer and designing new therapies.
