Integrating concurrent navelbine and cisplatin to hyperfractionated radiotherapy in locally advanced non-small cell lung cancer patients treated with induction and consolidation chemotherapy: feasibility and activity results.
OBJECTIVE
The purpose of this study was to determine the effectiveness and toxicity of a new combination schedule based on concurrent navelbine, cisplatin and hyperfractionated radiotherapy in patients with locally advanced NSCLC treated with platinum and gemcitabine induction and consolidation chemotherapy.


METHODS
The 37 patients with pathological confirmed advanced NSCLC (non-surgical stages IIIA and IIIB) were included in the study. All of them were assessable for survival and 32 for response. The treatment schedule consisted of cisplatin (100 mg/m2) or carboplatin (400 mg/m2) on day 1 with gemcitabine (1000 mg/m2) on days 1, 8 and 15. Treatment was given every 28 days for two courses, followed by concurrent administration of accelerated modified hyperfractionated radiotherapy, with concomitant boost, with a total dose of 61.64 Gy administered for 5 weeks, with cisplatin and navelbine, for two courses, finally followed by two courses of the same initial chemotherapy.


RESULTS
Four patients achieved complete response (12.5%) and 14 (44%) partial response, for an overall objective response rate of 56.5%. After a minimum follow-up duration of 35.5 months, median progression free survival was 12.2 months. The median survival was 15.4 months with actuarial 1-, 2- and 3-year survival of 67, 21 and 15%, respectively. The main toxicity was hematological. There was esophagitis (grades III and IV) in 30% of the patients and there were two treatment-related deaths.


CONCLUSIONS
Combined treatment with concurrent radiotherapy and chemotherapy in non-surgical NSCLC is an acceptable treatment modality. However, the toxicity was not negligible.
