Breast cancer specialist reports advance in treatment of triple-negative breast cancer — ScienceDaily

“Impact of the Addition of Carboplatin and/or Bevacizumab to Neoadjuvant Once-Per-Week Paclitaxel Followed by Dose-Dense Doxorubicin and Cyclophosphamide on Pathologic Complete Response Rates in Stage II to III Triple-Negative Breast Cancer: CALGB 40603 (Alliance)” was accepted as a rapid publication and published online this month by the Journal of Clinical Oncology. It will come out in print in September. Because of its rapid growth rate, many women with triple-negative breast cancer receive chemotherapy to try to shrink it before undergoing surgery. With the standard treatment, the cancer is eliminated from the breast and lymph nodes in the armpit before surgery in about one third of women…

Novel immunotherapy vaccine decreases recurrence in HER2 positive breast cancer patients — ScienceDaily

One of only a few vaccines of its kind in development, GP2 has been shown to be safe and effective for breast cancer patients, reducing recurrence rates by 57%. Further, women with the highest overexpression of HER2 (known as HER2 +3) had no cancer recurrences when they were administered the vaccine after completing trastuzumab (Herceptin), a type of immunotherapy drug known as a monoclonal antibody. HER2 is an oncoprotein that promotes tumor growth and is expressed to some extent in 75-80% of breast cancers. “This is an important and different avenue in immunotherapy research, in that we are investigating ways to prevent cancer recurrence by stimulating the immune system to treat cancer,” says principal investigator Elizabeth Mittendorf, M.D., Ph.D., associate professor of Surgical Oncology…

Patient navigation may aid in breast cancer treatment in high-risk populations — ScienceDaily

Using data from a previously published, multi-center study funded by the National Cancer Institute, researchers aimed to identify the possible benefits of assigning patient navigators to women recently diagnosed with breast cancer. According to the results, women were more likely to start recommended treatment when assisted by one of these trained specialists. For example, they were more likely to start hormonal therapy, which is considered the gold standard in treatment for certain types of breast cancer. Naomi Ko, MD, MPH, instructor of medicine in the Section of Hematology Oncology at Boston University School of Medicine and a practicing breast oncologist at Boston Medical Center, stresses the need for further investigation…

Genomic analysis of prostate cancer indicates best course of action after surgery — ScienceDaily

“We are moving away from treating everyone the same,” says first author Robert Den, M.D., Assistant Professor of Radiation Oncology and Cancer Biology at Thomas Jefferson University. “Genomic tools are letting us gauge which cancers are more aggressive and should be treated earlier with radiation, and which ones are unlikely to benefit from additional therapy.” Although surgery for prostate cancer is meant to be curative, in some men, the cancer can regrow. Doctors have developed high risk criteria based on clinical factors, but these criteria are imperfect predictors of cancer returning, or recurrence. Only about 50 percent of high risk patients ever go on to develop metastases, raising the question of whether those who receive additional therapy are being overtreated. …

Adding element to standard treatment in post-gemcitabine metastatic pancreatic cancer improves survival

“Patients with metastatic pancreatic cancer or pancreatic cancer in general have very limited options,” said study author Andrea Wang-Gillam, assistant professor in the Division of Oncology at Washington University in St. Louis, USA. “These patients just simply don’t do well. …

Unique study focuses on combined treatment approach for locally advanced pancreatic cancer

Locally advanced pancreatic cancer has the lowest survival rate of any solid tumor, with a cumulative five-year survival rate of only 4 percent for all stages of disease. Surgery is rarely an option for patients because tumors often involve vital blood vessels. Chemotherapy and radiotherapy given concurrently remain the mainstay treatment, yet to-date, no treatment has had a significant impact on improving outcomes. “To move the needle forward toward prolonged survival and better treatment outcomes, our research team created a combined investigational regimen for patients with locally advanced pancreatic cancer,” said Richard Tuli, MD, PhD, a radiation oncologist in the Department of Radiation Oncology and a member of the Samuel Oschin Comprehensive Cancer Institute. …
