Drug for Blood Pressure also Treats Lung Cancer

...control of blood pressure also shrinks lung cancer tumors in mice, suggesting a new way to prevent or treat the deadly cancer, according to scientists. // Reporting in the journal Cancer Research, the scientists said that in mice treated with the hormone, angiotensin-(1-7), tumor volume decreased by 30 per...

A Novel Treatment for KSHV-infected Lymphomas

...a treatment resulted in a marked regression of all tumors in the treated animals in two weeks. These results demonstrate that p53 reactivation via Nutlin-3a is an efficient treatment for KSHV-lymphomas in mice and suggest a novel therapeutic strategy for treatment of these fatal virus-induced malignancies a...

Vitamin C Could Help in Curbing Cancer

...n C was low or absent in the body, cancer cells in tumors could make more blood vessels grow well and resist chemotherapy. "This also means that a lack of vitamin C increases tumor growth and prevents effective treatment," she said. "It follows that restoring vitamin C to normal levels means less tumor gr...

Gene Study Offers Hope of Potent Anti-cancer Drugs

Study Aims to Find Which Breast Cancer Patients Need Chemotherapy

Most postmenopausal women with small breast tumors don’t need chemotherapy to reduce their recurrence risk after lumpectomy//. To try to determine who does, a test that measures a tumor’s aggressiveness based on its DNA will be tested nationally in more than 10,000 of these women. “The dilemma ph...

CT Scans may Not Benefit Lung Cancer Patients

...ately. Lung cancers are of different types. Some tumors are pretty much harmless. The extra surgical treatment prompted by screening can be harmful, researchers say. The death rate from lung cancer surgery is 5 percent. In addition, 20 percent to 40 percent of people who have such surgery have serio...

No Carrier Necessary: This Drug Delivers Itself

...und that the nanocrystals of HPPH were taken up by tumors in vivo, with efficacy comparable to conventional, surfactant-based delivery systems. A patent has been filed on this work. "In this case, the drug itself acts as its own carrier," said Haridas Pudavar, Ph.D., UB research assistant professor of c...

Drugs to Tackle Anemia may Be Playing Dracula

...patients receiving chemotherapy, may actually make tumors grow faster and increase the risk of death, if given in high doses. This is according to the FDA’s official Richard Pazdur, who announced the new "black box' warning. The ‘black box’ warning cautions that the drugs should be used at the lowest do...

Scientists Identify 120 New Cancer Genes
