Severing nerves may shrink stomach cancers: Botox injections slow growth of stomach tumors in mice
“Scientists have long observed that human and mouse cancers contain a lot of nerves in and around the tumor cells,” said Dr. …

The criteria — developed in Edinburgh — will help to select which girls should be offered the opportunity to freeze some tissue from their ovaries for use in the future. Doctors are optimistic that the frozen tissue could one day help young cancer survivors to have children of their own…
“Our studies suggest that limiting inflammatory signaling may be an effective, less toxic approach to altering the cancer-promoting effects of obesity and improving patient response to hormone therapy,” said Linda A. deGraffenried, PhD, associate professor of nutritional sciences at The University of Texas in Austin. The study found that women whose body mass index (BMI) was greater than 30 and had estrogen receptor alpha (ERα)-positive breast cancer had a 52 percent lower rate of recurrence and a 28-month delay in time to recurrence if they were taking aspirin or other NSAIDs. “These results suggest that NSAIDs may improve response to hormone therapy, thereby allowing more women to remain on hormone therapy rather than needing to change to chemotherapy and deal with the associated side effects and complications,” said deGraffenried…

The Prostate Cancer Prevention Trial was a randomized, double-blind, placebo-controlled trial which tested the efficacy of finasteride, a drug used for prostate cancer prevention. This study was conducted by SWOG — a cancer research cooperative group that designs and conducts multidisciplinary clinical trials. …
Analyzing these modifications can provide important clues to the type of tumor a patient has, and how it will respond to different drugs. For example, patients with glioblastoma, a type of brain tumor, respond well to a certain class of drugs known as alkylating agents if the DNA-repair gene MGMT is silenced by epigenetic modification…
Chloroquine is a well-known medicine with a good safety profile that has been in use since World War 2 for the treatment of malaria and certain auto-immune diseases, including rheumatoid arthritis. …
The study, led by Dr. Xiaosong Wang, assistant professor of medicine — hematology and oncology and of molecular and cellular biology at Baylor, published today in Nature Communications and focused on the more aggressive molecular subtype of the estrogen-receptor positive breast cancer known as luminal B breast cancer. “While expressing the estrogen receptor, the luminal B breast cancers usually have higher tumor grade, larger tumor size, and poor prognosis, with most cases difficult to treat by endocrine therapy,” said Wang, the lead and corresponding author on the report. “We wanted to gain a deeper understanding about the genetic alterations underlying this particular form of breast cancer, because we do not know about what malfunctions potentially cause this form to be more aggressive.” In the study, Wang and colleagues identified a particular gene fusion on the estrogen receptor itself (hybrid gene formed from two previously separate genes) that was preferentially present in a subset of samples of tumors that were luminal B and ER-positive. …
The effort is known as the Institutional Multidisciplinary Paradigm to Accelerate Collaboration and Translation (IMPACT). The aim — as illustrated in the acronym — is to enhance the way cancer discoveries are translated from the laboratory bench to patient bedside and back again. …
The study, published online August 3 in the journal Nature Genetics, shows that high mortality rates among head and neck cancer patients tend to occur only when mutations in the tumor suppressor gene coincide with missing segments of genetic material on the cancer genome’s third chromosome. The link between the two had not been observed before because the mutations co-occur in about 70 percent of head and neck tumors and because full genetic fingerprints of large numbers of cancer tumors have become available only recently…
