Most women with early-stage breast cancer avoid extensive lymph node removal

Until now, it was unclear to what extent surgeons were following the recommendations of a landmark clinical trial published more than four years ago, known as the American College of Surgeons Oncology Group Z0011, or ACOSOG Z-11, trial. Those researchers reported that most early-stage breast cancer patients with tumor in their sentinel lymph node (the first draining node) who undergo lumpectomy do not benefit from surgical removal of the remaining lymph nodes in the underarm area, called completion axillary lymph node dissection (ALND). That study found no difference in cancer recurrence1 and five-year survival2 between patients who underwent ALND and those who did not but were monitored for recurrences…

Research aims to reduce health care disparities

Gwendolyn P. Quinn, Ph.D., scientific director of the Survey Methods Core Facility at Moffitt, identified physicians largely operate under a, “don’t ask, don’t tell” policy that prohibits open and honest dialogue between doctor and patient about cancer risk. The study highlights that LGBTQI populations face barriers to health insurance such as when partnerships and marriages are not legally recognized; concerns about disclosure in a health care setting, discrimination, misconceptions, legal and financial barriers and the disenfranchised stress and distress of caregiving same-sex partners. …

Ebola whole virus vaccine shown effective, safe in primates

The vaccine, described today (March 26, 2015) in the journal Science, was developed by a group led by Yoshihiro Kawaoka, a University of Wisconsin-Madison expert on avian influenza, Ebola and other viruses of medical importance. It differs from other Ebola vaccines because as an inactivated whole virus vaccine, it primes the host immune system with the full complement of Ebola viral proteins and genes, potentially conferring greater protection. “In terms of efficacy, this affords excellent protection,” explains Kawaoka, a professor of pathobiological sciences in the UW-Madison School of Veterinary Medicine and who also holds a faculty appointment at the University of Tokyo…

Bio-marker set forms the basis for new blood test to detect colorectal cancer

Max Mazzone (VIB/KU Leuven): “This research demonstrates how important it is to gain a thorough understanding of the role of our immune system in cancer. In this case, this knowledge will hopefully result in a new, more sensitive test to detect colorectal cancer at an early stage, so that more patients can be cured. I hope that we can soon find an industrial partner to help us achieve the following step, which is the development of the test.” Colorectal cancer: a growing medical problem In 2012, a total of 1.4 million people worldwide were diagnosed with colorectal cancer, this figure is expected to increase to 2.4 million by 2035. This is a condition that affects a growing number of people each year. …

Switch that might tame most aggressive of breast cancers

The Sydney-based research team has found a gene that drives the aggressive disease, and hopes to find a way to ‘switch it off’. The aggressive form of triple-negative breast cancer appears to arise from stem cells, while the more benign form appears to arise from specialised cells. …

Natural extract shows promise for preventing breast cancer, study suggests

“Doctors, patients and researchers are looking for alternative treatments for triple negative breast cancer, and people are always looking for ways to prevent cancer,” said Patrick Martin, Ph.D., associate professor at North Carolina Agricultural and Technical State University and leader of the study. “How awesome would it be to be able to say: Here, take a daily vitamin tablet from the rose plant to possibly help prevent or treat cancer? It’s a natural product that we found to be effective, with no known side effects.” Triple negative breast cancer draws its name from the fact that the cancer cells in these tumors lack the three growth factor receptors that are normally targeted during breast cancer treatment. …

Immunotherapy delays recurrence for stage III and IV ovarian cancers

“This is cutting edge medicine for ovarian cancer,” said Jonathan Oh, MD, a gynecologic oncologist at Texas Oncology, P.A., in Dallas. Dr. Oh presented the results of a preliminary study on the vaccine at the Society of Gynecologic Oncology (SGO) Annual Meeting on Women’s Cancer on March 28 in Chicago…

New therapeutic target may improve treatment for brain cancer

The research will be presented at the American Society for Pharmacology and Experimental Therapeutics (ASPET) Annual Meeting during Experimental Biology 2015. Monteagudo’s research indicates a new possible chemotherapeutic target for treating GBM: transglutaminase 2 (TG2), a multifunctional protein that can regulate cell adhesion and motility. Given these documented functions of TG2, Monteagudo and her colleagues in the laboratory of Gail Johnson, Ph.D., at the University of Rochester, were interested in determining if TG2 played an important role in GBM cell growth. …
