Lymph node ratio predicts RT benefit for oral cancer
January 3, 2013 -- Radiation therapy (RT) can benefit some patients with oral cavity squamous cell carcinoma, but they can suffer acute as well as long-term toxicities. The use of lymph node ratios may help identify which patients will benefit the most, according to an article published online in Radiotherapy and Oncology.
Rad therapy doesn't help survival for stage I endometrial cancer
December 31, 2012 -- A Cochrane update evaluating radiation therapy for stage I endometrial cancer patients has again concluded that the treatment doesn't affect survival outcomes. But its findings, published in the Journal of the National Cancer Institute, sparked some controversy.
