- W2232172076 abstract "18509 Background: To evaluate the efficacy and toxicity of concurrent/consolidation chemoradiotherapy versus sequential chemoradiotherapy in unresectable stage III non-small cell lung cancer (NSCLC). Methods: Thirty-two patients with stage III unresectable NSCLC were randomly assigned to one of the two treatment arms. In the sequential arm, patients received induction chemotherapy with docetaxel (75 mg/m2) repeated every 3 weeks for 3 cycles, followed by thoracic radiotherapy at a dose of 61Gy in 33 fractions over 6.5 weeks. In the concurrent/consolidation arm, the same radiotherapy was started on day 2 with two concurrent cycles of (PE): cisplatin 50 mg/m2 on days 1, 8, 29, and 36; etoposide 50 mg/m2 on days 1 through 5 and 29 through 33. Then these patients received consolidation therapy with docetaxel started 4–6 weeks after concurrent chemoradiotherapy, repeated every 3 weeks for 3 cycles at a dose of 75 mg/m2. Results: The overall response rate was higher in concurrent/ consolidation arm (62.5%) than in sequential arm (43.7%), (P=0.031). The median survival was 19 months in concurrent/consolidation arm and 13.6 months in the sequential arm, (P=0.001). The 2- year survival rate was better in concurrent/consolidation arm (43.7%) than in the sequential arm (25%), (P=0.032). Median progression- free survival was longer in concurrent/consolidation arm (11.9 months) than in sequential arm (8 months), (P=0.071). The major and most frequent toxicity was neutropenia, which was 43.7% in concurrent/consolidation arm versus 56.2% in sequential arm, (P=0.09). However, esophageal toxicity (≥ grade 3) was relatively higher in concurrent/consolidation arm 25% versus 12.5% in sequential arm, (P= 0.05). Brain metastases was the most common site of distant failure in both treatment arms. Locoregional failure was more frequent in sequential arm (37.5%) than in concurrent/ consolidation arm (18.7%), (P=0.039). Conclusions: Consolidation docetaxel after concurrent cisplatin/etoposide with radiotherapy in stage III NSCLC was feasible, tolerable and can be safely administered with relatively low incidence of radiation esophagitis. In addition, treatment outcomes compared favorably with the sequential chemoradiotherapy. No significant financial relationships to disclose." @default.
