Predicting ovarian cancer survival by counting tumor-attacking immune cells

Scientists at Fred Hutchinson Cancer Research Center have developed a new method for counting a special class of cancer-fighting cells — called tumor-infiltrating T lymphocytes, or TILs — reliably, quickly and cheaply in patients with early stage and advanced ovarian cancer. They describe their findings online Dec. 4 in Science Translational Medicine. …

New means of growing intestinal stem cells

The small intestine, like most other body tissues, has a small store of immature adult stem cells that can differentiate into more mature, specialized cell types. Until now, there has been no good way to grow large numbers of these stem cells, because they only remain immature while in contact with a type of supportive cells called Paneth cells. In a new study appearing in the Dec. …

Hysterectomized women may benefit from testosterone

New research from Brigham and Women’s Hospital (BWH) has found that testosterone administration in women with low testosterone levels, whom previously had undergone hysterectomy with or without oophorectomy, was associated with improvements in sexual function, muscle mass and physical function. This research appears in the November 27, 2013 online issue of Menopause…

Negative BRCA testing may not always imply lowered breast cancer risk

Women with certain mutations in their BRCA1 or BRCA2 genes are at increased risk for breast cancer. However, if a woman who comes from a BRCA family tests negative for her family-specific BRCA mutation, her risk for breast cancer is considered to be the same as someone in the general population, according to the National Cancer Institute. This study, however, suggests that it may not always be true. "We found that women who test negative for family-specific BRCA2 mutations have more than four times the risk for developing breast cancer than the general population," said Gareth R. …

First breast biopsy system offering real-time monitoring, guidance

First diagnostic tool is clinical imaging (mainly Mammography and Ultrasound) but suspicious findings usually require a biopsy to confirm the diagnosis; 2% of women who undergo a screening mammogram will require some type of breast biopsy (1,3 million women each year in Europe). Breast biopsy is an image-guided procedure that can use different imaging technologies. Apart from US-guided biopsy, which is a manual procedure with limited indications, all current solutions are based on discrete scans of static images taken at different steps during the procedure. …

Women prescribed hormone therapy should use caution when taking apigenin supplement

A new study shows that when the supplement apigenin is ingested in a diet at the same concentration as subjects received during IV injections in previous studies — the benefits were reversed leading to a higher incidence of cancerous tumors in subjects receiving progestin. "Typically, hormone replacement therapies improve the lives of menopausal women and achieve very good results," said Salman Hyder, the Zalk Endowed Professor in Tumor Angiogenesis and professor of biomedical sciences in the College of Veterinary Medicine and the Dalton Cardiovascular Research Center. "However, research has proven that in women receiving therapies that involve a combination of the natural component estrogen and the synthetic progestin, a higher incidence of breast cancer tumors can occur." Hyder explains that many women normally have benign lesions in breast tissue. These lesions don’t typically form tumors until they receive the "trigger" that attracts blood vessels to cells essentially feeding the lesions causing them to form and expand — in this case, progestin is the trigger…

Adult survivors of childhood cancer at risk of early aging

Researchers also found that frail health was associated with a greater risk for adult childhood cancer survivors of death and chronic disease. Being frail was defined by the presence of at least three of the following — weakness, self-reported exhaustion, physical inactivity, low muscle mass and slow walking speed. …

Obesity a major risk factor in developing basal-like breast cancer

In a study published online by the journal Breast Cancer Research and Treatment, a team led by Liza Makowski, assistant professor with the UNC Gillings School of Global Public Health and member of the UNC Lineberger Comprehensive Cancer Center, and Sneha Sundaram, PhD, a post-doctoral fellow in the Makowski Lab, outlined the biological mechanisms where obesity can create a favorable environment for the growth of basal-like breast cancer tumors. "Obesity is widespread and is one of the few risk factors for breast cancer that we may be able to control, hence our intention in this study was to better understand the molecular mechanisms and/or biomarkers of obesity-related basal like breast cancer that could impact disease prevention," said Dr…
