Adding Radiation Therapy To Chemotherapy Improves Survival In Patients With High-risk Breast Cancer

For patients with high-risk breast cancer treated with radical mastectomy and adjuvant chemotherapy, the addition of radiation therapy leads to better survival outcomes with few long-term toxic effects, according to a 20-year follow-up of a randomized trial, which appears in the January 19 issue of the Journal of the National Cancer Institute. The British Columbia randomized radiation the...

Duke Experiments Boost Radiation's Cancer-Killing Effects

Scientists have shown they can dramatically enhance radiation's cancer-killing effects by blocking a "master switch" in cancer cells that promotes cancer growth. Blocking a protein called HIF-1 after radiation therapy doubled the length of time it took for human cancers to begin growing again in mice, said the radiation biologists from the Duke Comprehensive Cancer Center. Each therapy alo...

Jefferson researchers find nanoparticle shows promise in reducing radiation side effects

A gene responsible for the production of a protein called vasostatin may prove a promising new way of treating pancreatic cancer, suggests research published ahead of print in Gut. Pancreatic cancer is the fifth leading cause of cancer deaths in the developed world, and is extremely difficult to treat. Only 3% of affected patients are still alive five years after diagnosis, a survival rate...

Radiation-killed bacteria vaccine induces broad immune response in mice

Vaccines made with bacteria killed by gamma irradiation, rather than by standard methods of heat or chemical inactivation, may be more effective, say researchers supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH). Vaccines made from gamma-irradiated bacteria also may not need to be kept cold; an advantage in settings whe...

Antioxidants protect health tissue in people undergoing radiation therapy.

A recent finding by Indian scientists revealed that two antioxidants in black pepper and turmeric- piperine and curcumin were found to help protect the bacterial DNA from damage by irradiation in test organism. Spices with antioxidants property have radio protective effect and protecting organisms like Escherichia role and Bacillus megaterium organisms (taken for study) against of gamma...

Radiation before surgery cuts cancer recurrence

According to a report, giving radiation to surgical treatment for rectal cancer may not make much difference in the survival of patients. But the findings suggest that the radiation treatments given before surgery may help improve the patient's quality of life by reducing the rate of cancer recurrence at or near the original tumor site in the rectum. In about 15% to 45% of patients who...

UV Radiation induces Melanoma

Children who suffer sunburn very early in life are far more likely to suffer the most dangerous form of skin cancer, suggest researchers. In humans, melanocytes, the pigment-producing skin cells where melanoma develops, are on the surface of the skin. It is thought that some melanomas are the result of genetic damage caused when the UV radiation strikes these pigment cells. Babies and young child...

Low-radiation treatment for brain tumours

A new method of treating childhood brain tumours, aimed at reducing the risk of damage to normal tissue, is to be trialled at hospitals around the US. Researchers will enrol 50 children suffering from medulloblastoma – the most common malignant childhood brain tumour – who will be treated with lower radiation and increased chemotherapy doses than those currently used. // In the US, ab...

Lack of solar radiation causes cancer

Exposure to UV-B radiation may cause skin cancer, but it also prevents many other cancers through activating vitamin D. According to many, UV-B - the solar radiation that causes sunburn// - as a risk factor for melanoma, and other skin cancers. That is generally true, but what is not generally realised is that the reverse may also be the case - that UV-B prevents cancer. Dr.William Gr...
