pHLIP, a novel technology to locate and treat tumors
Research teams at Yale University and the University of Rhode Island have demonstrated a new way to target and potentially treat tumors using a short piece of protein that acts like a nanosyringe to deliver "tags" or therapy to cells, according to a report in the Proceedings of the National Academy of Sciences. view more (2007-05-02)
Three new lung tumor subtypes identified in DNA profiling study
A new study has identified three subtypes of non-small-cell lung cancer tumors, a finding that may provide valuable clinical information about patient survival in early- or late-stage disease, how likely the cancer is to spread and whether the tumor will prove resistant to chemotherapy. view more (2006-10-31)
Herbal Menopause Therapy a Good Fit for Breast Cancer Patients?
When it comes to understanding the effectiveness and safety of using herbal therapies with other drugs, much is unknown. Now, a University of Missouri researcher will study how black cohosh - an herbal supplement often used to relieve hot flashes in menopausal women - interacts with tamoxifen, a common drug used to treat breast cancer. view more (2008-10-08)
Molecular signature may identify cisplatin-sensitive breast tumors
Researchers at the Massachusetts General Hospital (MGH) Cancer Center have identified a subgroup of hard-to-treat breast cancers that may be sensitive to the drug cisplatin, rarely used in the treatment of breast tumors. view more (2007-04-20)
Researchers find how a common genetic mutation makes cancer radiation resistant
Many cancerous tumors possess a genetic mutation that disables a tumor suppressor called PTEN. Now researchers at Washington University School of Medicine in St. Louis have shown why inactivation of PTEN allows tumors to resist radiation therapy. view more (2009-06-10)
Combination therapy reduces tumor resistance to radiation
Radiation is used to treat a variety of tumors and the response of tumors to radiation is dependent on endothelial cell death, which in turn limits oxygen delivery to the tumor, causing hypoxia and tumor cell death. view more (2007-06-08)
Nanoparticle-delivered 'suicide' genes slowed ovarian tumor growth
Nanoparticle delivery of diphtheria toxin-encoding DNA selectively expressed in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect this therapy could be tested in humans within 18 to 24 months, according to a report in Cancer Research, a journal of the American Association for Cancer Research. view more (2009-07-30)
Research reveals molecular pathway behind invasive prostate cancers
University of Cincinnati (UC) cancer and cell biologists have identified a new molecular pathway key to the development of invasive prostate cancers. view more (2009-05-19)
Do cell phones increase brain cancer risk?
Major research initiatives are needed immediately to assess the possibility that using cellular phones may lead to an increased risk of brain tumors. view more (2008-10-21)
OU Cancer Institute Scientists Identify New Cancer Stem Cell Marker; Developing Drug to Stop Cancer Recurrence
After years of working toward this goal, scientists at the OU Cancer Institute have found a way to isolate cancer stem cells in tumors so they can target the cells and kill them, keeping cancer from returning. view more (2008-09-12)
New imaging method shows whether treatment for advanced prostate cancer is working
Researchers at the University of Michigan Comprehensive Cancer Center have identified a new imaging technique that can measure the effectiveness of treatment for prostate cancer that has spread to the bones. The technique involves measuring diffusion of water within tumors. view more (2007-04-16)
More kidney cancer is detected and treated early, yet death rate rises
The number of cases of kidney cancer has been rising over the last two decades, and new research from the University of Michigan Comprehensive Cancer Center shows that this increase is driven largely by the detection of small, presumably curable, kidney masses. view more (2006-09-20)
Northwestern researchers launch Avastin trial for pancreatic tumors
Avastin is designed to inhibit Vascular Endothelial Growth Factor (VEGF), a protein that plays an important role in tumor angiogenesis or blood vessel formation, and maintenance of existing tumor vessels. view more (2006-02-22)
Study: Patients 75 years and older with brain tumors may benefit from more aggressive treatment
A new study from University Hospitals Case Medical Center (UHCMC) finds that elderly patients - 75 years old and older-- with malignant brain tumors are not treated as aggressively as patients between 65 and 75 years old. view more (2008-05-20)
Researchers make discovery in colon cancer prevention
A new study finds that individuals who have low expression of the "Celebrex gene," 15-PGDH, are actually resistant to Celebrex treatment when used to prevent colon cancer. view more (2009-05-19)
What is the influence of tumor removal on the serum level of carbohydrate's antibody?
Cancer immune surveillance is considered to be important in the anti-tumor protection of the host. The growing tumor escapes the immune control under the immunosuppressive conditions. view more (2008-10-08)
Anti-angiogenesis treatment improves hearing in some NF2 patients
Treatment with the angiogenesis inhibitor bevacizumab improved hearing and alleviated other symptoms in patients with neurofibromatosis type 2 (NF2). view more (2009-07-09)
A low-carb diet may stunt prostate tumor growth
A diet low in carbohydrates may help stunt the growth of prostate tumors, according to a new study led by Duke Prostate Center researchers. view more (2007-11-14)
Protein plays broader role than originally thought in neurofibromatosis
Neurofibromatosis type I is a common genetic disorder in which tumors grow along certain types of nerves and can also affect other tissues such as bone, heart, and skin. view more (2006-08-11)
Mayo Clinic study finds focused ultrasound treatment of uterine fibroids long term symptom relief
A noninvasive, outpatient treatment for noncancerous uterine tumors provides sustained relief from symptoms, according to a new Mayo Clinic led collaborative study. view more (2007-07-31)
