The over-the-counter supplement lipoic acid may have a small beneficial effect in slowing the loss of gray matter in the brains of people with progressive forms of multiple sclerosis, according to new research. However, the randomized controlled trial found that it did not improve the primary clinical outcome measured by walking speed.

A new study from Memorial Sloan Kettering Cancer Center finds that in colorectal cancer, not all regulatory T cells are created equal. One subtype suppresses cancer growth while another aids it. The findings could help improve immunotherapy treatment for the majority of patients with colorectal cancer, and potentially for other cancers.

A blood test could help doctors decide which patients with colon cancer should receive anti-inflammatory medication along with chemotherapy after surgery, according to new study in JAMA Oncology. Based on data from an Alliance for Clinical Trials in Oncology study, this finding could lead to more personalized treatments and better outcomes for patients.

However, a cure ― completely ridding the body of the virus — has only been documented in a handful of patients who underwent complex and high-risk bone marrow transplants for life-threatening blood cancers such as leukemia or lymphoma.
