Ifosfamide, etoposide, and thoracic irradiation therapy in 163 patients with unresectable small cell lung cancer.
One hundred sixty-three patients with small cell lung cancer were treated with six courses, at 3-week intervals, of ifosfamide (5 g/m2) with mesna and etoposide. Thoracic radiotherapy was delivered to the limited stage (LS) patients. The complete response rate (CR, determined clinically and radiologically) was 76% for the 78 LS patients with a further 14% partial response (PR). The majority of the CRs were confirmed on a follow-up bronchoscopy. The CR rate was 27% for extensive stage (ES) patients with another 38% undergoing a partial response. The median survival for LS patients was 11 months, (16 months for CR confirmed by rebronchoscopy) and 8 months for ES patients. The 2-year actuarial survival for LS patients is 27%, follow-up ranges from 12 months to 30 months with a median of 22 months. Toxicity was not severe for the patient population, of whom only 20% had a good performance status before chemotherapy. Parental antibiotics were required on 4% of all 844 chemotherapy courses and 12% of courses were delayed due to side effects. The majority of responses occurred within the first two courses of chemotherapy and there was a corresponding improvement in the patients' symptoms and performance status. The regimen produced rapid tumor response with corresponding improvement in symptoms without marked toxicity and allowed further treatment development.
