Chemotherapy after bladder cancer surgery may improve survival

Dr. Brilliant no comments

Clinical trials have established the benefit of giving chemotherapy prior to surgery (neoadjuvant chemotherapy) for patients with bladder cancer. However, clinical trials exploring giving chemotherapy after surgery (adjuvant chemotherapy) have been difficult to interpret and many of the trials closed early due to poor accrual without providing an answer. Lead researcher Matthew Galsky, MD and colleagues used a large database of patients diagnosed with cancer in the United States. Specifically, the study found that patients receiving adjuvant chemotherapy after surgical treatment had improved overall survival when compared to patients that received surgical treatment alone with only post-surgical observation. …

Breast density helps better predict breast cancer risk

The study, “Volumetric Breast Density Improves Breast Cancer Risk Prediction,” was presented during the 2014 San Antonio Breast Cancer Symposium. …

Diagnostic tool Oncotype DX associated with reduction in chemotherapy rates post-surgery in younger women with breast cancer — ScienceDaily

Dr. Expert no comments

Mariana Chavez Mac Gregor, M.D., assistant professor, health services research and breast medical oncology, will present the findings at a poster session of the 2014 San Antonio Breast Cancer Symposium. Oncotype DX is a 21-gene assay used to help estimate the likelihood of recurrence in women with early-stage breast cancer and, thus, determine those who may or may not benefit from adjuvant chemotherapy. The National Comprehensive Cancer Network includes its use for women with lymph node-negative, hormone receptor (HR)-positive and HER2-negative disease. …

Immune function marker does not predict benefit of trastuzumab in HER-2+ breast cancer patients — ScienceDaily

Dr. Expert no comments

And since trastuzumab, and not chemotherapy alone, is the standard of care for the HER2-positive sub-class of breast cancer, there is no need to test for these lymphocytes in HER2-positive patients in order to predict outcome, say researchers from Mayo Clinic in Florida. These findings, presented at the 2014 San Antonio Breast Cancer Symposium, don’t mean that immune function in this class of cancer isn’t important — just that it is likely more complicated than measuring the number of these lymphocytes, says the study’s lead author, Edith A. Perez, M.D., deputy director at large, Mayo Clinic Cancer Center, and director of the Breast Cancer Translational Genomics Program at Mayo Clinic in Florida. …

Galeterone shows activity in a variant form of castration-resistant prostate cancer — ScienceDaily

Dr. Expert no comments

Associate professor Mary-Ellen Taplin, of the Dana-Farber Cancer Institute, Boston, USA, will tell the 26th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Spain,�that galeterone was well tolerated by patients in the ARMOR2 trial, and also lowered PSA levels in a subset of men with CRPC that was resistant to other drugs that target the cancer, such as enzalutamide and abiraterone. “Recent data have shown that a variant of the androgen receptor called AR-V7, found in tumour cells circulating in the blood of patients with metastatic CRPC, predicted resistance to treatment with enzalutamide and abiraterone,” she will say. “Indeed, we believe AR-V7 and other, related variants are a mechanism of resistance in this disease and patients who have them may have a poorer prognosis.” Researchers believed that galeterone could be effective against CRPC because it disrupts the androgen receptor signalling pathways that are involved in the cancer, and preclinical work has shown it is active against the AR-V7 variant…

Herceptin plus taxol highly effective in low-risk breast cancer

Dr. Expert no comments

The study is the first major trial to examine the Herceptin-Taxol combination in patients who have a type of breast cancer with the biology known as small, node-negative, HER2+. Results were presented during the 2013 San Antonio Breast Cancer Symposium. "This is great news for patients and their physicians," said Kathy Albain, MD, of Loyola University Medical Center, who is one of the co-authors of the national multicenter study. "This study identifies a new treatment option for this population of patients that is highly effective and has minimal side effects." First author is Sara Tolaney, MD, of the Dana-Farber Cancer Institute…
