Improved treatment
High-precision radiation therapy improves cervical cancer outcomes
Nov. 10,
2009 -- School of Medicine researhers have shown that highly targeted radiation therapy improves survival and lessens treatment-related complications in cervical cancer patients. The technique, called intensity-modulated radiation therapy, is widely accepted for treating many cancers of the pelvic region, head and neck, and central nervous system, but its for cervical cancer is not as common.

Saving lives
New treatments improve outlook for pancreatic cancer patients
Oct. 21,
2009 -- A team of surgeons and oncologists at the Siteman Cancer Center at the School of Medicine and Barnes-Jewish Hospital is aggressively tackling pancreatic cancer — one of the deadliest forms of cancer — and conducting clinical trials of innovative treatment regimens.

| Cancer survivor Kathy Ferrara and daughter Natalie continue their dialogue after participating in StoryCorps, a national oral history and research project. |
Cancer is a difficult diagnosis to acknowledge — especially what a parent with can-cer must explain. A StoryCorps project captures the emotional stories of survivors and may help others to say what must be said.

Estrogen benefit
Low-dose estrogen shown safe and effective for metastatic breast cancer
Aug. 18,
2009 --
When estrogen-lowering drugs no longer control metastatic breast cancer, the opposite strategy might work. Raising estrogen levels benefited 30 percent of women whose metastatic breast cancer no longer responded to standard anti-estrogen treatment, according to research conducted at the School of Medicine and collaborating institutions.

The seeds of colon cancer
Scientists identify cells in fruit fly gut that start tumors
Aug. 17,
2009 -- Tumor growth can start from stem cells in the gut, say researchers studying fruit flies at the School of Medicine. They found that tumors can grow from adult stem cells that have lost a specific tumor-suppressor gene. The gene, Apc, has previously been implicated in human gastrointestinal cancers, including colon cancer.

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 the School of Medicine. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

Cancer: weapons and suspects
WUSTL leads study of pediatric brain tumors
Aug. 10,
2009 -- The National Cancer Institute (NCI) has awarded a five-year, $4 million grant to researchers at the School of Medicine to use genetically-engineered mice to study the origins and potential treatments of pediatric brain tumors. David H. Gutmann, the Donald O. Schnuck Family Professor of Neurology, is principal investigator of the grant, which is part of the NCI's Mouse Models of Human Cancers Consortium. He is also on staff at Barnes-Jewish and St. Louis Children's hospitals.

Researchers at the School of Medicine have shed new light on a process that fixes breaks in the genetic material of cells. The scientists studied protein molecules that have an important role in homologous recombination, which is one way that cells repair breaks in the DNA double helix. Their findings could lead to ways of enhancing chemotherapy drugs that destroy cancer cells by damaging their DNA.

Chronic wounds sow cancer seeds
Mice with skin condition help scientists understand tumor growth
July 6,
2009 -- Cancerous tumors sometimes form at the site of chronic wounds or injury, but the reason why is not entirely clear. Now researchers at theSchool of Medicine have engineered mice with a persistent wound-like skin condition, and the mice are helping them understand the tumor-promoting effects of long-standing wounds and injuries.
