    Abstract:
    The purpose of this study was to search for the maximal tolerated dose of cisplatin in the cisplatin plus high-dose epirubicin combination for patients with non-small-cell lung cancer. The following range of cisplatin dosages were tested in a phase I study: 75, 90, 105, and 120 mg/m2 in combination with epirubicin 120 mg/m2 every 3 weeks. Eligibility consisted of previously untreated stage IIIb or IV non-small-cell lung cancers, Eastern Cooperative Oncology Group Performance Status less than or equal to 2, age less than or equal to 70 years, measurable disease, adequate blood counts, chemistry, cardiac function, and no brain metastasis. The maximal tolerated dose was defined as the dose level of cisplatin for which two of three patients or three of six patients developed one or more limiting toxicities during the first course of therapy. Afterward, the maximal tolerated dose of cisplatin was adopted in a subsequent phase II study. Three centers enrolled 42 patients: 18 in phase I and 24 in phase II. The maximal tolerated dose was almost reached at the last dose level (i.e., 120 mg/m2). Taking into account the total duration of the treatment, the real dose intensity for patients treated at the fourth dose level (120 mg/m2) did not differ from that of the third dose level (105 mg/m2). The latter dosage was therefore considered as the maximal tolerated one. In the subsequent phase II study, the median number of cycles received per patient was three (range: one to eight). Fifty percent required a dose reduction of either epirubicin, cisplatin, or both. The main toxicity was neutropenia, resulting in 10 episodes of febrile grade IV neutropenia requiring readmission. Other toxicities were mild to moderate. There was no toxic-related death. On intent-to-treat analysis, 10 patients (33%) achieved an objective response. Among them were three complete responders. Median survival was 8 months. We observed neither detraction nor improvement of quality of life as assessed using the European Organization for Research and Treatment of Cancer QLQ-C30-LC13. Given every 3 weeks in combination with epirubicin 120 mg/m2, the maximal tolerated cisplatin dose is 105 mg/m2. This combination yields activity in non-small-cell lung cancer.
