Wine may offer radioprotective effect for breast cancer patients

Drinking wine while undergoing radiation treatment for breast carcinoma may reduce the incidence of skin toxicity in breast cancer patients, according to a study in the August issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO).

Discovery of compounds that selectively kills cancer stem cells

The cancer stem cells that drive tumor growth and resist chemotherapies and radiation treatments that kill other cancer cells aren't invincible after all. Researchers reporting online on August 13th in the journal Cell, a Cell Press publication, have discovered the first compound that targets those cancer stem cells directly.

Researchers tackle aggressive cancer cells head on

A multi-institutional team of Boston-area researchers has discovered a chemical that works in mice to kill the rare but aggressive cells within breast cancers that have the ability to seed new tumors.

Antigenics’ Oncophage cancer vaccine trial starts enrolling patients

Antigenics Inc. (NASDAQ:AGEN) today announced that the Brain Tumor Research Center at the University of California, San Francisco, has begun enrolling patients into a Phase 2 clinical trial of Oncophage (vitespen) in combination with the standard of care - radiation therapy plus Temodar (temozolomide) - for newly diagnosed glioma patients.

Giant pituitary adenoma can be safely removed through nasal route

It’s even worse than being told you have a brain tumor: having a tumor so large, it’s in a category all its own. Giant pituitary adenoma is a so-called “benign” tumor that can cause visual loss and impair many of the body’s most basic functions. But fortunately, even the largest of these giant tumors—which can grow to the size of an egg and invade nearby structures--can be treated effectively using a multimodality approach starting with minimally invasive surgery through the nose, according to a new study at the John Wayne Cancer Institute at Saint John’s Health Center.

Potential new treatment for drug resistant brain tumors

Dr. Karen Newell, Ph. D., the lead researcher for bio technology company Viral Genetics (Pink Sheets: VRAL), will address the 4th Annual Aspen Symposium on Brain Tumor Immuno- and Stem Cell Therapy. Her presentation will highlight the potential for combining chemotherapy with compounds that interfere with the ability of brain tumor cells to generate the energy needed to repair chemotherapy induced DNA damage.

Aspirin improves survival after colorectal cancer diagnosis

Men and women who were diagnosed with colorectal cancer and began regular use of aspirin had a lower risk of overall and colorectal cancer death compared to patients not using aspirin, according to a study in the August 12 issue of JAMA.

Regular use of aspirin after colorectal cancer diagnosis may reduce the risk of cancer death

In the August 12 issue of the Journal of the American Medical Association, the study's authors also find that the aspirin-associated survival advantage was seen primarily in patients with tumors expressing the COX-2 enzyme, a characteristic of two-thirds of colorectal cancers.

Oxygen nanosensor could improve tumor imaging

A new material developed at the University of Virginia - an oxygen nanosensor that couples a light-emitting dye with a biopolymer - simplifies the imaging of oxygen-deficient regions of tumors. Such tumors are associated with increased cancer aggressiveness and are particularly difficult to treat.

Researchers launch study into search-and-destroy antigen for deadly skin cancer

UT Southwestern Medical Center researchers are studying a new antigen to see whether it can track down and kill cancer cells in patients with recurring melanoma, the leading cause of skin cancer deaths.

STAT3 is required for proliferation and maintenance of multipotency in glioblastoma stem cells

In a study published online in advance of print in Stem Cells, Tufts researchers report that the STAT3 gene regulates cancer stem cells in brain cancer. Cancer stem cells have many characteristics of stem cells and are thought to be the cells that drive tumor formation. The researchers report that STAT3 could become a target for cancer therapy, specifically in Glioblastoma multiforme (GBM), a type of malignant and aggressive brain tumor.

'Nanobee' drug delivery to tumors

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

Discovery of a potential target for metastatic cancer

The deadliest part of the cancer process, metastasis, appears to rely on help from macrophages, potent immune system cells that usually defend vigorously against disease, researchers at Albert Einstein College of Medicine of Yeshiva University report.

New molecule blocks lymphangiogenesis

Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. In an article in the Aug. 9, 2009 online edition of Nature Medicine, they report the identification of a new molecule known as soluble VEGFR-2 that blocks lymphangiogenesis - the growth of lymphatics - but not blood vessel growth.

Canadian health care system may be getting 'bum rap'

Amid the debate about reforming heath care in the United States, it's tough to turn on your television these days without hearing a political ad condemning the Canadian health care system.

Estrogen-dependent switch tempers killing activity of immune cells

The sex hormone estrogen tempers the killing activity of a specific group of immune cells, the cytotoxic T cells (CTLs), which are known to attack tumor cells and cells infected by viruses. The key player in this process is a cytotoxic T cell molecule which has been known for a long time and which scientists have named EBAG9.

Cost-effectiveness of Cetuximab in metastatic colorectal cancer

From a health-care system perspective, it may be more efficient to use the drug cetuximab only in colorectal cancer patients whose tumors have a wild-type KRAS gene, according to a study published online August 7 in the Journal of the National Cancer Institute.
