Popis: Summary Context: The most satisfactory treatment for patients with locally advanced non-small-cell lung cancer (NSCLC) is combination chemotherapy–radiotherapy (CT–RT). The optimal treatment modalities remain to be determined. Objective: We conducted a multicenter phase II trial of the docetaxel–radiotherapy combination after induction chemotherapy with cisplatin–vinorelbine. The main endpoint was the objective response rate. Patients and methods: Patient with inoperable stage locally advanced NSCLC received induction chemotherapy consisting of two cycles of cisplatin 100 mg/m 2 on D1 and vinorelbine 25 mg/m 2 on D1, D8, D15 and D22. Patients with responses or stable disease then received concurrent RT–CT consisting of 25 mg/m 2 /week docetaxel and single-fraction radiotherapy (66 grays (Gy) in 33 fractions) over 6.5 weeks. Results: Fifty-six patients were enrolled from 1 July 2000 to 31 December 2001. Sixteen patients left the trial after induction chemotherapy, eight for progression, five for toxicity, and two for intercurrent events. One patient underwent surgery after induction chemotherapy. In total, 40 of the 56 patients received RT–CT. Twelve (30%) of these 40 patients experienced grade III or IV pulmonary or esophageal toxicity. In the intention-to-treat analysis, the objective response rate was 46.4% (95% CI 33.0–60.2). The median time to progression was 6.2 months [1.1–26.0]. The median survival time was 13 months [0.3–44.9 months]. Nine patients progressed during RT–CT, six with brain metastases. Conclusion: Weekly docetaxel with concurrent radiotherapy, following chemotherapy is acceptable. The tumor response rate is moderate. Further trials are required to determine the risk–benefit relationship of this treatment schedule, and the possible benefit of adding other cytotoxic drugs.
