Protein holds back growth of head and neck tumors
A protein associated with the growth of head and neck tumors may be a tumor suppressor that could prevent the spread of cancer when it is expressed above normal levels. view more (2006-02-01)
New drug agent knocks out multiple enzymes in cancer pathway
A team of 24 researchers from the U.S., Europe, Taiwan and Japan and led by University of Illinois scientists has engineered a new anti-cancer agent that is about 200 times more active in killing tumor cells than similar drugs used in recent clinical trials. view more (2009-03-26)
FLT PET Assesses Treatment Response on Tumor Growth—Not Size—With Non-Hodgkin's Lymphoma
Positron emission tomography (PET)—with the radiolabeled thymidine analog [18F]Fluorothymidine (FLT)—is "a promising, sensitive tool" for assessing drug effects on tumor growth in patients with diffuse large B-cell lymphoma. view more (2006-06-07)
Innovative movies show real-time immune-cell activity within tumors
Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists at The Wistar Institute have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues. view more (2006-11-21)
Cancer stem cells: know thine enemy
Stem cells -- popularly known as a source of biological rejuvenation -- may play harmful roles in the body, specifically in the growth and spread of cancer. view more (2007-12-26)
FOXO factor promotes survival of oxygen-deprived cancer cells
Scientists report that an evolutionarily conserved transcription factor may have both positive and negative effects on the growth of tumors, depending on whether or not the tumor cells have enough oxygen. view more (2007-12-28)
PET scan shows during treatment if radiation is shrinking lung tumor, U-M study shows
Lung cancer patients may not need to wait till their radiation treatment is over to know if it worked. A PET scan several weeks after starting radiation treatment for lung cancer can indicate whether the tumor will respond to the treatment. view more (2007-07-19)
Cardia resection for perforated gastroesophageal cancer
Iatrogenic perforation of cancer of the esophagus or the gastroesophageal (GE) junction is a severe complication. view more (2009-07-08)
Breast cancer etiology may vary by subtype
Women's reproductive and lifestyle characteristics can be linked to different invasive breast cancer subtypes. Data on 2544 breast cancer cases, presented in the open access journal Breast Cancer Research, suggests that traditional risk factors for development of the condition are associated with different kinds of tumor. view more (2009-05-22)
Mutations common to cancer and developmental disorder examined in a novel disease model
New research sheds light on a common link between tumor formation and Costello Syndrome, an inherited developmental disorder in which patients have cardiac defects, mild mental retardation, and face-shape abnormalities. view more (2008-12-22)
Nanoparticles carry chemotherapy drug deeper into solid tumors
A new drug delivery method using nano-sized molecules to carry the chemotherapy drug doxorubicin to tumors improves the effectiveness of the drug in mice and increases their survival time. view more (2007-06-27)
Carbohydrate restriction may slow prostate tumor growth
Restricting carbohydrates, regardless of weight loss, appears to slow the growth of prostate tumors, according to an animal study being published this week by researchers in the Duke Prostate Center. view more (2009-05-27)
Gene dose affects tumor growth
Researchers at Johns Hopkins and Ohio State University have found that the number of copies of a particular gene can affect the severity of colon cancer in a mouse model. view more (2008-01-04)
When Cancer Runs in the Family
Almost all tumor types have a genetically based form Most cancers occur sporadically. At least 5.5 percent of cancer cases are based on a genetic predisposition. These are usually identified because first-degree relatives develop the same type of tumor. So far, scientists have presumed that only a few types of tumor have such a familial form.... view more...

Refusal of suicide order: Why tumor cells become resistant
Cells with irreparable DNA damage normally induce programmed cell death, or apoptosis. However, this mechanism often fails in tumor cells so that transformed cells are able to multiply and spread throughout the body. view more (2008-06-24)
Blood protein may hold key to stopping tumor growth in cancer patients
A recent discovery by researchers at Wake Forest University School of Medicine could clear the way for a new drug that inhibits tumor growth in cancer patients and could potentially help in the healing of wounds. view more (2009-04-01)
Angiogenesis inhibitor improves brain tumor survival by reducing edema
The beneficial effects of anti-angiogenesis drugs in the treatment of the deadly brain tumors called glioblastomas appear to result primarily from reduction of edema - the swelling of brain tissue - and not from any direct anti-tumor effect. view more (2009-03-30)
Drug combination might offer hope for patients deadly brain tumors
Brain cancer patients with the poorest prognosis -- those with a type of deadly tumor known as glioblastoma multiforme (GBM) -- may survive longer with a drug that chokes off a tumor's blood supply. view more (2007-10-19)
New tumor markers determine therapy intensity
Characteristic changes in the DNA of medulloblastoma, the most frequent malignant brain tumor in childhood, indicate precisely how aggressively the tumor will continue to spread and what the chances of disease relapse are. view more (2009-03-18)
MU researcher links hormone replacement therapy to breast cancer
Millions of post-menopausal women use hormone replacement therapy (HRT) as a method to reduce symptoms associated with menopause. In a recent University of Missouri study, researchers found that one of the hormones used in HRT, a synthetic progestin, could be a major factor in promoting breast cancer. view more (2008-04-02)
