The paper published by these EORTC Imaging Group investigators highlights the most recent developments in MRI and PET and elucidates how these techniques can be used to detect bone metastases at an early stage as well as monitor the response of these to treatment. …
The researchers, whose results were published today in Cell, successfully grew six prostate cancer organoids from biopsies of patients with metastatic prostate cancer and a seventh organoid from a patient’s circulating tumor cells. …
Researchers studying infertility in mouse models found that, unlike similar types of cells that develop into sperm, the stem cells that express PAX7 can survive treatment with toxic drugs and radiation. If the findings hold true in people, they eventually could lead to new strategies to restore or protect fertility in men undergoing cancer treatment. “Unfortunately, many cancer treatments negatively impact fertility, and men who receive such treatments are at high risk of losing their fertility…
Writing in the Sept. 2 issue of Nature Communications, the researchers describe animal and cell-culture experiments that show increased levels of so-called signaling molecules released by breast cancer cells. These molecules cause lymphatic endothelial cells (LECs) in the lungs and lymph nodes to produce proteins called CCL5 and VEGF. CCL5 attracts tumor cells to the lungs and lymph nodes, and VEGF increases the number of blood vessels and makes them more porous, allowing tumor cells to metastasize and infiltrate the lungs. …
The study findings defy the conventional belief that the two treatment interventions offer equal survival, and show the need to revisit some standards of breast cancer practice in the modern era. The research was presented at the 2014 Breast Cancer Symposium by Catherine Parker, MD, formerly a fellow at MD Anderson, now at the University of Alabama Birmingham. In the 1980s, both US-based and international randomized clinical studies found that BCT and mastectomy offered women with early stage breast cancer equal survival benefit…
The study, to be presented at the 2014 Breast Cancer Symposium, finds that those barriers that still exist are socio-economic, rather than medically-influenced. Meeghan Lautner, M.D., formerly a fellow at MD Anderson, now at The University of Texas San Antonio, will present the findings. BCT for early stage breast cancer includes breast conserving surgery, followed by six weeks of radiation. …
These interim results of the 5-year Phase II clinical trial using the experimental regimen are being presented at the Breast Cancer Symposium 2014 in San Francisco by Anthony E. Dragun, M.D., vice chair and associate professor of radiation oncology at the University of Louisville. Dragun, a radiation oncologist with University of Louisville Physicians, launched the trial three years ago at UofL’s James Graham Brown Cancer Center, a part of KentuckyOne Health and the only site offering the experimental regimen in the United States…
The study evaluated two groups of 31 men with prostate cancer that had spread and whose blood levels of prostate-specific antigen (PSA) were still rising despite low testosterone levels. Investigators gave each man either enzalutamide (Xtandi) or abiraterone (Zytiga) and tracked whether their PSA levels continued to rise, an indication that the drugs were not working. In the enzalutamide group, none of 12 patients whose blood samples tested positive for AR-V7 responded to the drug, compared with 10 responders among 19 men who had no AR-V7 detected. In the abiraterone group, none of six AR-V7-positive patients responded, compared with 17 responders among 25 patients lacking AR-V7. …
