Radiation plus chemo quadruples survival time for fatal brain cancer

Over four times as many patients with a rapidly fatal type of brain cancer, glioblastoma multiforme (GBM), who are treated with the chemotherapy drug temozolomide (TMZ) and radiation therapy, can live for four years after diagnosis, compared to those who receive only radiation treatment, according to updated results of a large, international trial presented at the Plenary I session on October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Preventing lung scarring may extend lives of lung cancer patients

Researchers have found that using a special type of drug called a pharmaceutical monoclonal antibody to block the integrin beta6-TGF-beta pathway prevents a serious side effect of radiation therapy for lung cancer patients – pulmonary fibrosis (scarring of the lungs), thereby extending patients' lives and improving their quality of life, according to a study presented at the Plenary I session on October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.
