We conducted a phase III study to compare the survival impact of concurrent versus sequential treatment with radiotherapy (RT) and chemotherapy (CT) in unresectable stage III non-small-cell lung ...cancer (NSCLC).
Patients were randomly assigned to one of the two treatment arms. In the sequential arm, patients received induction CT with cisplatin (120 mg/m2) on days 1, 29, and 57, and vinorelbine (30 mg/m2/wk) from day 1 to day 78, followed by thoracic RT at a dose of 66 Gy in 33 fractions (2 Gy per fraction and 5 fractions per week). In the concurrent arm, the same RT was started on day 1 with two concurrent cycles of cisplatin 20 mg/m2/d and etoposide 50 mg/m2/d (days 1 to 5 and days 29 to 33); patients then received consolidation therapy with cisplatin 80 mg/m2 on days 78 and 106 and vinorelbine 30 mg/m2/wk from days 78 to 127.
Two hundred five patients were randomly assigned. Pretreatment characteristics were well balanced between the two arms. There were six toxic deaths in the sequential arm and 10 in the concurrent arm. Median survival was 14.5 months in the sequential arm and 16.3 months in the concurrent arm (log-rank test P = .24). Two-, 3-, and 4-year survival rates were better in the concurrent arm (39%, 25%, and 21%, respectively) than in the sequential arm (26%, 19%, and 14%, respectively). Esophageal toxicity was significantly more frequent in the concurrent arm than in the sequential arm (32% v 3%).
Although not statistically significant, clinically important differences in the median, 2-, 3-, and 4-year survival rates were observed, with a trend in favor of concurrent chemoradiation therapy, suggesting that is the optimal strategy for patients with locally advanced NSCLC.
Approximately 30% of lung cancer cases are diagnosed in patients > 70 years of age. Standard chemotherapy regimens are generally considered too toxic for elderly patients. We conducted a multicenter ...phase II trial to determine the efficacy and safety of carboplatin combined with vinorelbine every 4 weeks as first-line treatment for advanced non-small-cell lung cancer (NSCLC) in elderly patients.
Patients were eligible if they were aged >OR= 70 years, had stage IIIB (with pleural effusion) or stage IV NSCLC, had a performance status of 0/1, had not previously received chemotherapy, and had normal organ function. Forty patients (31 men and 9 women) were enrolled and received 3-5 courses of treatment. Median age was 72 years (range, 70-82 years). Eighty percent of patients had stage IV NSCLC, with squamous cell (n=21), adenocarcinoma (n=12), and undifferentiated (n=7) histologies.
Forty patients were assessable for toxicity and 32 for treatment response. Among these 32 patients, 8 had a partial response (intent-to-treat response rate, 20%), and 10 (25%) had stable disease. The median survival was 7.8 months (range, 4-11.6 months). The 1- and 2-year survival rates were 25% and 7%, respectively; median time to progression was 4.3 months (range, 0.2-13.8 months). Grade 3/4 neutropenia was seen in 27 patients (68%), and grade 3/4 anemia was seen in 5 patients (13%). One patient died of febrile neutropenia during treatment. The main nonhematologic adverse effect was fatigue (grade 3/4 in 18% of patients).
Carboplatin/vinorelbine is well tolerated by elderly patients with extensive-stage NSCLC. Efficacy is low but similar to that of other treatments used in this setting.
