A prospective randomised trial of adjuvant vinorelbine (VIN) and cisplatin (CIS) in completely resected stage 1B and II non small cell lung cancer (NSCLC) Intergroup JBR.10

Abstract

7018 Background: In meta-analyses platinum based adjuvant chemotherapy using 2nd generation regimens increased cure rate by 5% in completely resected NSCLC. JBR.10 was undertaken to determine whether the 3rd generation regimen VIN/CIS prolonged survival in this clinical setting. Methods: Patients with completely resected stage 1 (T2N0) or stage 2 (excluding T3N0) NSCLC were stratified by nodal status (N0 vs. N1) and ras mutation status (present vs. absent vs. unknown) and randomised to receive 4 cycles of VIN (25mg/m2 weekly x 16 weeks) plus CIS (50mg/m2 days 1 and 8 q 4 weeks x 4) or follow up alone; VIN dose was reduced from 30mg/m2 shortly after the study started due to unacceptable toxicity. The endpoints of the study were survival (OS), recurrence-free survival (RFS), quality of life (QOL) and toxicity. Results: 482 patients were randomized between 1994 and 2001. Patients: age 61 years, 65% male, 51% PS 1, 53% N1, 24% ras mutation present. 45% of patients had T2N0, 40% T2N1 and 15% T1N1. 53% had adenocarcinoma. Grade 4 neutropenia, was common with febrile neutropenia in 7%, predominantly in patients receiving VIN 30mg/m2. The commonest non-hematologic toxicities for VIN/CIS patients were fatigue (77%), nausea (76%), anorexia (53%), vomiting (46%), sensory neuropathy (45%) and constipation (44%). Two patients died of drug-related toxicity [1 febrile neutropenia, 1 pulmonary fibrosis]. The most common cause of death was NSCLC (including 1 patient with 2nd primary NSCLC), while 3 patients died from toxicity related to later anti-cancer therapy, 9 patients died of other primary malignancies, and 21 from other causes. Overall survival was significantly prolonged for VIN/CIS patients (94 months vs. 73 months; HR 0.69, p=0.011), as was RFS (not reached vs. 46.7 months; HR 0.6, p 0.0003). 5-year survival for VIN/CIS patients was 69% compared to 54% for patients followed expectantly. 38 patients developed 2nd malignancies. Conclusions: This is the first randomized clinical trial demonstrating that a 3rd generation platinum-based doublet prolongs OS and RFS after surgery in early stage NSCLC.
