Research led by David Litchfield of The University of Western Ontario has identified how biochemical pathways can be "rewired" in cancer cells to allow these cells to ignore signals that should normally trigger their death. It's one way that cancer cells may become resistant to therapy. The findings are now published in Science Signaling. http://medicalxpress.com/news/2011-06-cancer-cells-death.html Cancer Wed, 08 Jun 2011 13:12:12 EST news226757521 An interim analysis of a phase II clinical trial indicates that a novel experimental agent for chronic lymphocytic leukemia (CLL) is highly active and well tolerated both in patients who are undergoing treatment for the first time and those who have relapsed and are resistant to other therapy. http://medicalxpress.com/news/2011-06-experimental-agent-highly-cll-patients.html Cancer Mon, 06 Jun 2011 09:42:26 EST news226572134 An analysis of data on heart and lung transplant recipients indicates that patients who had transplant surgery performed at nighttime did not have a significantly different rate of survival up to one year after organ transplantation, according to a study in the June 1 issue of JAMA. http://medicalxpress.com/news/2011-05-nighttime-transplant-surgery-poorer-survival.html Other Tue, 31 May 2011 16:26:31 EST news226077965 Colorectal cancer patients with defects in mismatch repair--one of the body's systems for repairing DNA damage--have lower recurrence rates and better survival rates than patients without such defects, according to a study published online May 19th in the Journal of the National Cancer Institute. http://medicalxpress.com/news/2011-05-dna-affects-colon-cancer-recurrence.html Cancer Thu, 19 May 2011 16:23:38 EST news225040984 Long-term survival rates for patients with advanced prostate cancer suggest they can be good candidates for surgery, Mayo Clinic researchers have found. Their study found a 20-year survival rate for 80 percent of patients diagnosed with cancer that has potentially spread beyond the prostate, known as cT3 prostate cancer, and treated with radical prostatectomy, or surgery to remove the prostate gland. Previously, patients found to have cT3 prostate cancer were offered radiation or hormone treatment, but not radical prostatectomy. http://medicalxpress.com/news/2011-05-advanced-stage-prostate-cancer-patients-year.html Cancer Sun, 15 May 2011 13:28:31 EST news224684805
