Cancer Research: New treatment options for a fatal leukemia ♦ 'Major player' in skin cancer genes identified ♦ Non-genetic cancer mechanism found

Prostate cancer: Why some tumors are resistant to radiotherapy  Scientists believe they have identified how some tiny regulatory molecules in cells can make prostate cancers resistant to radiotherapy. It is hoped that this new development could pave the way for more effective treatments -- allowing a lower dose of radiotherapy to be used while prolonging the lives of thousands of men.
Gene therapy may improve survival of patients with recurrent ovarian cancer Use of gene therapy to deliver a protein that suppresses the development of female reproductive organs may improve the survival of patients with ovarian cancer that has recurred after chemotherapy, which happens 70 percent of the time and is invariably fatal.
New treatment options for a fatal leukemia In industrialized countries, acute lymphoblastic leukemia is the most common form of cancer in children. An international research consortium has now succeeded in decoding a specific form of this leukemia, which is regarded as incurable, and in obtaining insights for new therapeutic possibilities.
'Major player' in skin cancer genes identified A subgroup of genetic mutations that are present in a significant number of melanoma skin cancer cases has been defined by a multidisciplinary team of researchers. Their findings shed light on an important mutation in this deadly disease, and may lead to more targeted anti-cancer therapies
Non-genetic cancer mechanism found Cancer can be caused solely by protein imbalances within cells, a study of ovarian cancer has found. The discovery is a major breakthrough because, until now, genetic aberrations have been seen as the main cause of almost all cancer.
