title: Pilot study of sequential vinorelbine and cisplatin followed by docetaxel for selected IIIB and stage IV non-small cell lung cancer.
abstract: Vinorelbine, cisplatin and docetaxel are known to be efficacious in non-small cell lung cancer (NSCLC). This limited institution pilot study evaluated the novel strategy of sequencing active first line agents prior to progression. The primary objective of this study was to assess the toxicity profile in anticipation of a larger cooperative group standard phase II study. Patients with selected stage IIIB and IV NSCLC, Southwest Oncology Group (SWOG) performance status (PS) of 1 or less and measurable or evaluable disease were eligible. Treatment was cisplatin 100 mg/m(2) day 1 and 29, vinorelbine 25 mg/m(2) weekly for 8 weeks, followed by docetaxel 100 mg/m(2) every 21 days for four cycles if no progression. If grade IV neutropenia developed, G-CSF 5 mcg/kg/day was used in subsequent cycles. Of 18 eligible patients, 17 patients had stage IV disease with a median age of 66 years (range 48-80). Eight patients had a SWOG PS of 1, 10 had a PS of zero. Six of eighteen patients received all 8 weeks of vinorelbine/cisplatin and six of eight patients who went on to receive docetaxel received all four planned cycles; only two patients overall received all planned therapy. One grade III/IV event each of cardiotoxicity (myocardial infarction), renal toxicity (acute renal failure), anemia and thrombocytopenia occurred with vinorelbine and cisplatin, and 2 Grade IV hypersensitivity reactions, manifested by severe back pain with docetaxel occurred. Three deaths occurred during the study, all during treatment with vinorelbine and cisplatin: one due to neutropenic sepsis; one from a pulmonary embolism; and one secondary to severe hypoglycemia in a diabetic patient. Of the 16 patients evaluable for response after vinorelbine/cisplatin, there were two complete responses (12.5%) and three partial responses (19%) for an overall response rate of 31% (95% CI 8-58). One additional patient who received docetaxel experienced a partial response. Two patients remain alive (21+ and 18+ months, respectively). The 1-year survival was 44%.
  
  
  CONCLUSIONS
  This sequence, as defined, was tolerated marginally well in patients with advanced NSCLC. Granulocytopenia was the major toxicity requiring dose adjustments throughout the sequence. Based on response rates and tolerability that were somewhat comparable to other regimens in this disease setting, a modified version of this program, adjusted to decrease the incidence of grade III and IV toxicity, was selected as one arm of a recent randomized phase II trial in the Southwest Oncology Group (SWOG), S9806, evaluating sequential therapy in advanced NSCLC.
