Researchers identify biomarker to predict response of colon cancer patients to chemotherapy regimen
Researchers at Fox Chase Cancer Center have identified a biomarker that can predict how well individual colon cancer patients will respond to a common chemotherapy regimen.
Lower risk of heart disease and stroke in people with Type 2 diabetes taking atorvastatin
A daily dose of the cholesterol-lowering drug atorvastatin (Lipitor) can reduce the risk of a first major cardiovascular event (heart attack or stroke) by more than one third in people with Type 2 diabetes, according to the results of the CARDS study presented today at the American Diabetes Association's 64th Scientific Sessions in Orlando, USA.
Camptosar in combination with targeted therapies shows survival benefit
Combination of Camptosar® (irinotecan HCL injection) and AvastinTM (bevacizumab) shows survival benefit in first-line treatment of advanced colorectal cancer.
New study links common cholesterol-lowering drugs to reduced prostate cancer risk
Men who take even small amounts of common cholesterol-lowering drugs such as Lovastatin and Simvastatin have a significantly reduced risk of prostate cancer, according to a new study by Oregon Health & Science University Cancer Institute researchers.
Multicenter melanoma vaccine study demonstrates promising results
Results from the largest multi-site study to date evaluating a peptide-derived therapeutic vaccine for melanoma were released today by the Eastern Cooperative Oncology Group (ECOG) at the 40th Annual Meeting of the American Society of Clinical Oncology (ASCO) in New Orleans.

A drug originally developed to block the formation of blood vessels in tumors has been shown to overcome resistance to treatment with Gleevec in patients with gastrointestinal stromal tumors (GIST).
Studies show ACTOS(R) (pioglitazone HCl) has positive effects on various components of dyslipidemia
Two clinical studies presented at the American Diabetes Association's (ADA) Scientific Sessions showed that ACTOS® (pioglitazone HCl) has favorable effects on dyslipidemia (low HDL-C levels, high triglycerides and high levels of small, dense LDL-C) and insulin resistance.
Smart statistics for cancer diagnosis
CSIRO statisticians have developed a new way to subtype paediatric Acute Lymphoblastic Leukaemia (ALL), the most common form of cancer in children under 12.
New study shows Xeloda after surgery significantly increases number of patients free of colon cancer
New data from the X-ACT trial (Xeloda in Adjuvant Colon Cancer Therapy), involving almost 2,000 patients, was presented today at the American Society of Clinical Oncology (ASCO), demonstrating that Xeloda (capecitabine), a targeted oral chemotherapy, should replace the current standard therapy known as the Mayo Clinic regimen (intravenous 5-FU/LV) due to its superior efficacy and safety.
