OBJECTIVE: Chemotherapy of stage IIIA non-small cell lung cancer (NSCLC) using second generation, cisplatin-based combinations has shown to improve the results; however, the distant relapses remain the major problem. Encouraging results in the treatment of stage IV NSCLC with newer agents (gemcitabine, placlitaxel) has encouraged us to use them in stage III. The aim of this study was to assess feasibility and efficacy of induction chemotherapy with cisplatin and gemcitabine followed by surgery for patients with stage IIIA (N2) NSCLC. METHODS: From February 1996 to December 1999, 36 consecutive patients with mediastinoscopically staged N2 NSCLC received three cycles of cisplatin (80 mg/m(2), day 2) and gemcitabine (1200 mg/m(2), day 1+8) followed by surgery in responding patients. Patients with stable disease or even local progression received radiotherapy. All patients had clinical N2 disease (mediastinal lymph nodes metastasis) observed on CT scan. RESULTS: No major complications of the chemotherapy occurred. Twenty-five patients (70%) had a clinical partial response and were surgically explored, with 18 complete resections (70%). There were no in-hospital deaths, although four (16%) major complications: bronchopleural fistula (two), respiratory insufficiency (one), oesophagospleural fistula (one). In the total group of 36 patients, 3-year survival was 20%. So far, no patient without surgery has survived longer then 27 months; median survival was 8 months. In the group of the 25 patients who underwent surgery 3-year survival was 30%, with a median survival of 21 months. The difference is significant (P=0.0027). In the surgical group, the survival of patients with down staged disease (56%) was greater than that of patients with persistent N2 disease (44%) after chemotherapy (3-year survival of 59 and 0%, respectively; P=0.0013). CONCLUSION: induction chemotherapy with cisplatin and gemcitabine resulted in major tumour regression in a large percentage of patients with clinical N2 disease. In responding patients both the complete respectability rate and survival were higher when compared to historical controls. Survival was significantly better in patients down-staged to a mediastinal negative disease.
