Background: Gemcitabine-cisplatin (GP) combination is one of the most active and well tolerated regimens in advanced non-small cell lung cancer (NSCLC). The aim of this study is to evaluate the activity and toxicity of the GP regimen as a 21-day schedule in patients (pts) with stage IIIAN2-IIIB NSCLC. Patients and methods: From October 1997 to July 2000, 47 pts entered the study: 43 were eligible (40 men and three women); median age was 61 years (range 45-73); ECOG PS 0-1; histology was squamous (20 pts), adenocarcinoma (12 pts), large cell (five pts), and undifferentiated (six pts); stage was IIIAN2 (14 pts, 32.56%), and IIIB (29 pts, 67.44%). Malignant pleural effusion or superior vena cava syndrome was criteria of exclusion. Induction treatment consisted of three cycles of GP (G 1250 mg/m2 i.v. on days 1 and 8, and P 100 mg/m2 on day 8 every 3 weeks). Responding and stable pts underwent surgery (S) and/or radiotherapy (RT). Results: Following a minimum of two cycles, 39 pts were evaluable for response and 42 for toxicity. Two pts had complete responses (CR; 5.2%), 24 had partial response (PR; 61.5%), eight had stable disease (SD; 20.5%), and five had progressive disease (PRO; 12.8%). WHO grades 3 and 4 anaemia, neutropenia and thrombocytopenia were observed in two, four and two pts, respectively; non-haematological toxicity was moderate. After induction, stable and responding pts received either RT (18 pts) or S+RT (13 pts). Among the 16 resected pts, a radical complete resection was possible in 13 cases (81.3%), whereas tumour down-staging was observed in nine pts (56.2%). Conclusion: GP, as a 3-week neoadjuvant schedule, appears a safe and active regimen. Copyright © 2001 .

Abstract
Background: Gemcitabine-cisplatin (GP) combination is one of the most active and well tolerated regimens in advanced non-small cell lung cancer (NSCLC). The aim of this study is to evaluate the activity and toxicity of the GP regimen as a 21-day schedule in patients (pts) with stage IIIAN2-IIIB NSCLC. Patients and methods: From October 1997 to July 2000, 47 pts entered the study: 43 were eligible (40 men and three women); median age was 61 years (range 45-73); ECOG PS 0-1; histology was squamous (20 pts), adenocarcinoma (12 pts), large cell (five pts), and undifferentiated (six pts); stage was IIIAN2 (14 pts, 32.56%), and IIIB (29 pts, 67.44%). Malignant pleural effusion or superior vena cava syndrome was criteria of exclusion. Induction treatment consisted of three cycles of GP (G 1250 mg/m2 i.v. on days 1 and 8, and P 100 mg/m2 on day 8 every 3 weeks). Responding and stable pts underwent surgery (S) and/or radiotherapy (RT). Results: Following a minimum of two cycles, 39 pts were evaluable for response and 42 for toxicity. Two pts had complete responses (CR; 5.2%), 24 had partial response (PR; 61.5%), eight had stable disease (SD; 20.5%), and five had progressive disease (PRO; 12.8%).
