How to enhance non-thermal effects of ultrasound
In recent years HIFU has been widely used for the treatment of solid tumors, such as liver tumor, bone tumor, and breast cancer. The mechanism for therapeutic actions of HIFU includes thermal effects and non-thermal effects with the latter dominated by cavitational effects. view more (2008-12-29)
Gene signature may predict patient response to therapy for gastrointestinal stromal tumors
Researchers at Fox Chase Cancer Center uncovered a genetic pattern that may help predict how gastrointestinal stromal tumor (GIST) patients respond to the targeted therapy imatinib mesylate (Gleevec). view more (2009-05-15)
Gene therapy completely suppresses ovarian cancer growth in animal model
University of Pittsburgh School of Medicine researchers have used gene therapy to either completely abolish or significantly inhibit tumor progression in a mouse model of ovarian cancer. view more (2006-06-05)
Finding protection from tumor growth in unexpected places
Researchers have discovered that an enzyme commonly involved in regulating blood pressure also provides protection from tumor growth when strongly expressed in immune cells. view more (2007-06-06)
An effective target of biological therapy for hepatocellular carcinoma
It has been shown that constitutively activated STAT3 is detected in many HCC cell lines and tissues. This suggests that STAT3 is a promising molecular target for HCC gene therapy. view more (2009-06-15)
Sentinel lymph node biopsy is associated with breast cancer rates
The incidence of some early stage metastatic breast cancers is increasing, but this finding is likely explained by changes in clinical practice, according to a study published online June 26 in the Journal of the National Cancer Institute. view more (2007-06-27)
MGH Cancer Center researchers find new gene associated with Wilms tumor
Researchers at the Massachusetts General Hospital (MGH) Cancer Center have discovered a novel gene mutation associated with Wilms tumor, the most common pediatric kidney cancer. view more (2007-01-05)
Study provides documentation that tumor 'stem-like cells' exist in benign tumors
Cancer stem-like cells have been implicated in the genesis of a variety of malignant cancers. Research scientists at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute have isolated stem-like cells in benign (pituitary) tumors and used these "mother" cells to generate new tumors in laboratory mice. view more (2009-07-23)
MRI: A window to genetic properties of brain tumors
Doctors diagnose and prescribe treatment for brain tumors by studying, under a microscope, tumor tissue and cell samples obtained through invasive biopsy or surgery. view more (2008-03-25)
Novel marker of colon cancer
Colon cancer ranks second of all gastrointestinal malignant tumors, it is one of the leading causes of cancer-related deaths worldwide. view more (2008-10-24)
Long-term study shows low oxygen levels in prostate tumors can predict recurrence
Fox Chase Cancer Center researchers have discovered that low-oxygen regions in prostate tumors can be used to predict a rise in prostate-specific antigen (PSA) levels, a marker of tumor recurrence in prostate cancer. view more (2009-05-18)
Sidestepping cancer's chaperone
Cancerous tumors are wildly unfavorable environments. Struggling for oxygen and nutrients while being bombarded by the body's defense systems, tumor cells in fact require sophisticated adaptations to survive and grow. view more (2007-10-22)
Strengthening the tumor-fighting ability of T cells
When faced with cancer, the immune system dispatches cells, called T cells, to kill the tumor. But these killer cells often fail to completely eliminate the tumor because they're deactivated by a distinct population of T cells known as regulatory T cells. view more (2008-03-25)
Hebrew University researchers neutralize tumor growth in embryonic stem cell therapy
Researchers at the Hebrew University of Jerusalem have discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells. view more (2009-05-07)
Study identifies biomarker that safely monitors tumor response to new brain cancer treatment
A specific biomarker, a protein released by dying tumor cells, has been identified as an effective tool in an animal model to gauge the response to a novel gene therapy treatment for glioblastoma mulitforme. view more (2009-07-01)
St. Jude study offers new hope for children with kidney tumors deemed inoperable
Physicians at St. Jude Children's Research Hospital have demonstrated that children with bilateral Wilms tumor, a cancer of the kidneys, can retain normal function in both kidneys by undergoing a procedure called bilateral nephron-sparing surgery, even when preoperative scans suggest that the tumors are inoperable. view more (2008-03-25)
How can we know early who will benefit from tumor target therapy?
The precise tailoring of tumor target treatment for patients with cancer is an unmet challenge. The goal is to only administer treatments that have a high probability of being effective. view more (2007-11-26)
What's the role of beta-catenin in colorectal cancers?
Beta-catenin, a central molecule of the Wnt-signaling pathway was previously known to involve in the tumorigenesis of various gastrointestinal cancers such as gastric cancer and colon cancer. view more (2008-11-03)
Novel 3-D cell culture model shows selective tumor uptake of nanoparticles
A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists. view more (2007-08-23)
An AIDS-related virus tricks cells to become tumors, new Penn study finds
Researchers at the University of Pennsylvania School of Medicine have discovered how the Kaposi's sarcoma-associated herpesvirus (KSHV) subverts a normal cell process in order to promote tumor growth. view more (2006-11-09)
