Lung cancer is the most common cancer which has been mostly caused by tobacco chewing and smoking. Non Small Cell Lung Cancer (NSCLC) is a kind of Lung cancer which has found to have little disease prognosis to cancer treatment. NSCLC is mostly detected in the late stage of the disease and the survival rate of patients more than 1 year is very less.
Professor Mac Manus and his team of radiation oncologist from Peter MacCallum Cancer Centre in Melbourne, Australia have found that radiation therapy in patients with NSCLC is found to have a very good beneficial effect in reducing tumor. The researchers have found that the low dose of radiation not only gives supportive symptomatic care but also found to have curative effects.
Radiation therapy is given to cancer patients to kill the cancer cells by daily irradiation given daily for 60 days in most of the cancer patients by which the radiation is directed directly to the tumor site through computer guided programs mostly at a range of 2.25 Gy to kill cancer cells.
Radiation therapy has been the only source of effective treatment for NSCLC, which is found to offer Symptomatic treatment which was given to treat the symptoms caused by cancer but researchers found that radiation therapy offered better survival in these NSCLC.
The researchers conducted a survey from radiation therapy given to NSCLC patients between 1984 and 1990 to 2,300 patients who were given low dose of radiation therapy and they found that these patients had better therapy prognosis than patients who opted for other cancer treatment procedures. The researchers have reported the results of their trial in the Journal Cancer.
