Effect of radiotherapy on the treatment of patients with extensive stage small cell lung cancer.
GENETICS AND MOLECULAR RESEARCH(2014)
Abstract
Small cell lung cancer (SCLC) is an aggressive disease, in which more than 80% of patients present distant metastases at the time of first diagnosis. Chemotherapy is considered as the main treatment of extensive disease of SCLC (ED-SCLC), while the role of radiotherapy in the treatment of ED-SCLC is controversial. A case-control study was undertaken of patients diagnosed as ED-SCLC between 2004 and 2010. Fifty-eight patients with overall survival (OS) over 1 year were chosen, and another 58 patients with OS less than 1 year were selected as the control group, with the age, gender, metastasis or no metastasis of the liver, and the response after the first line of chemotherapy matched. The 1-year, 2-year, 3-year, and median OS of the 75 ED-SCLC patients who received radiation were 81.47, 29.89, 22.77%, and 17 months, respectively, and were 61.18, 23.53, 0%, and 16 months, respectively, for patients who did not receive radiation. The chi(2) test and odds ratio (OR) estimate demonstrated that these differences were statistically significant (chi(2) = 6.38, P = 0.0116; OR = 2.74, 95% confidence interval = 1.24-6.05). These results show that radiotherapy also plays a role in responding patients with extensive stage of SCLC.
