Hormones Produced By Heart Eliminated Human Cancers In Most Mice Treated
Hormones produced by the heart eliminated human pancreatic cancer in more than three-quarters of the mice treated with the hormones and eliminated human breast cancer in two-thirds of the mice, according to researcher David Vesely, a doctor at the James A. Haley Veterans Hospital in Tampa and a professor at the University of South Florida (USF).

Predicting Breast Cancer Patient Outcome: New Genes Identified
Not a day goes by without a new story about the environment. Although we often consider the environment on a global scale, cells in our body also have to contend with environmental factors. New studies from a team of researchers from the Research Institute of the MUHC and McGill University show that the environment surrounding breast cancer cells plays a crucial role in determining whether tumor cells grow and migrate or whether they fade away. Their study is the first to identify the genes behind this environmental control and correlate them with patient outcome. Their findings are published in this week’s issue of Nature Medicine.

Colorectal Cancer Gene Identified By Case Western Reserve University Researchers
Case Western Reserve University School of Medicine researchers published a study in The American Journal of Human Genetics identifying the hereditary components of colorectal cancer (CRC.) “Identification of Susceptibility Genes for Cancer in a Genome-wide Scan: Results from the Colon Neoplasia Sibling Study” is the first large linkage study of families with CRC and colon polyps in the country. Because only five percent of CRC cases are due to known gene defects, this NIH-funded study is designed to identify the remaining CRC-related susceptibility genes. The team built on a previous study which identified a specific region on chromosome 9q that harbors a CRC susceptibility gene. Upon review of a whole genome scan of all chromosome pairs in 194 families, the researchers were able to identify additional CRC gene regions on chromosomes 1p, 15q, and 17p.

Surgical Resection And Survival In Octogenarians And Younger Age Cohorts Of Patients Diagnosed With Non-small Cell Lung Cancer
Although fewer of them undergo surgery, lung cancer patients in their 80s fare equally well following surgery as their younger counterparts, researchers report. The findings offer doctors potentially valuable guidance in treatment options for elderly patients, according to researchers.
A research team from the Hoag Cancer Center in Newport Beach, California, observed 1,293 patients with lung cancer, 482 of whom underwent surgical treatment. The oldest patients were more likely to be male. Older patients were also more likely to have localized disease.

Smoking Is Related To Subset Of Colorectal Cancers
According to research from a team of Mayo Clinic scientists, smoking puts older women at significant risk for loss of DNA repair proteins that are critical for defending against development of some colorectal cancers.
In a study being presented at the annual meeting of the American Association for Cancer Research (AACR), the researchers found that women who smoked were at increased risk of developing colorectal tumors that lacked some or all of four proteins, known as DNA mismatch repair (MMR) proteins. These proteins keep cells lining the colon and rectum healthy because they recognize and repair genetic damage as well as mistakes that occur during cell division.

The Fallopian Tube Epithelium As The Field Of Origin For Ovarian Serous Carcinoma
Researchers report the fallopian tube fimbria rather than ovarian surface cells may be the site of origin for over 50 percent of sporadic and hereditary serous carcinoma, the most aggressive form of ovarian cancer. The new knowledge may enable earlier detection, better treatment and potential prevention of the most lethal gynecologic malignancy in Western countries.
