Hunt For The Blood Test To Determine Melanoma Survival Rates

New research will be breaking new ground in the search for a simple blood test that could tell whether a patient with melanoma has the condition in an aggressive form. Melanoma is the most aggressive form of skin cancer. Staging, which involves determining the size of the tumor and its extent of spread, is the best predictor of whether a patient will succumb to disease or survive.

Genetic testing may be valuable in treating colorectal cancer

For the 29,000 patients in the United States with metastatic colorectal cancer, chemotherapy with irinotecan is a standard treatment that has been shown to improve survival. But for more than one in 10 of these patients, a variation in their DNA means that this treatment could result in a severe reduction in their white blood cell count, leading to a high risk of bacterial infection and possible subsequent death. A new genetic test can identify those with the variation in order to lower the treatment dose -- however, it has been unclear whether the testing is worthwhile.

Is RTA a new potential option for the treatment of hydatid cysts?

Current treatment of cystic echinococcosis is surgery or percutaneous aspiration, injection and reaspiration (PAIR) using hypertonic saline or ethanol. It is aimed at causing permanent damage to the endocyst - the thin, delicate, and translucid inner membrane that produces the cystic fluid and generates new larval elements able to expand the infestation. Surgery and PAIR on liver and lung can result in biliary or bronchial fistulae, prompted by endocyst detachment; chemical cholangitis or pneumonia, due to passing of hypertonic saline or ethanol into the biliary or bronchial tree; and infection or abscess on the residual cyst cavity.
