Objective: We aimed to investigate the factors affecting the complete response(CR) to treatment and the effect of treatment response level on survival in patients with extensive stage small cell lung cancer (ES-SCLC) who received a combination of cisplatin and etoposide as first-line therapy.
Method: This retrospective analysis included 140 ES-SCLC patients, who were followed in an oncology clinic. Patients were divided into two groups as CR and non-CR according to radiological evaluation after first line chemotherapy. Clinical and demographical characteristics, pre-treatment hemogram parameters were obtained from archive files and compared between CR and non-CR patients.
Results: While CR was seen in 34 (24.3%) of all patients after the first line chemotherapy, 106 (75.7%) patient were in the non-CR group. On univariate analysis, predictors for complete response to treatment were, absence of brain metastasis , receiving 6 chemotherapy cycles and good performance status (p
