Abstract

The combination of etoposide and cisplatin (EP) remains one of the standard first‑line treatments for extensive‑disease small‑cell lung cancer (ED‑SCLC) We devised a one‑day modified EP regimen for better tolerance and convenience by modifying the dose and schedule of conventional EP with administration over 3‑5 consecutive days. The modified EP consists of two infusions of etoposide (120 mg/m2 each) and 60 mg/m2 of cisplatin on day 1 of a 21‑day cycle and a maximum of 6 cycles of treatment. A total of 36 consecutive ED‑SCLC patients were treated with the modified EP as first‑line therapy and retrospectively reviewed to assess the efficacy and safety of this regimen. Of the 36 patients, 24 exhibited confirmed objective tumor response (overall response rate of 66%, with a complete response rate of 3% and a partial response rate of 63%). The median overall survival (OS) was 11.8 months [95% confidence interval (CI): 7.9‑15.3] and the progression‑free survival (PFS) was 7.3 months (95% CI: 5.2‑9.7). The survival estimates at 1 year were 35 and 17% for OS and PFS, respectively. The chemotherapy treatment was well tolerated, with only one case of grade 4 non‑hematological adverse events, no grade 4 hematological toxicities and no treatment‑related deaths. The mean relative dose intensity of etoposide and cisplatin was measured to be 94.7 and 98.5% of the planned dose, respectively. Therefore, the modified EP warrants further clinical research regarding its effectiveness, toxicity profile and convenience of administration. Prospective randomized clinical trials are required to determine the therapeutic role of the modified EP as first‑line treatment in patients with ED‑SCLC.
