Abstract

This study was designed to evaluate the tolerability and therapeutic activity of paclitaxel and carboplatin combination therapy followed by radical thoracic radiotherapy with a concomitant boost technique with concurrent weekly paclitaxel in good performance status of patients with stage IIIA and IIIB non-small cell lung cancer. Patients with newly diagnosed inoperable non-small cell lung cancer received paclitaxel (100 mg/m(2)) as a 1-h infusion on d 1,8,15,28,35, and 42. Carboplatin (area under the curve of 6) was given as a 30-min infusion on d 1 and 28. Radiotherapy commenced on d 49 and was delivered with accelerated fractionation with concomitant boost at 1.8 Gy/fraction/d, 5 d/week and 1.5 Gy/fraction/d to a boost field as a second daily treatment for the last 10 treatment days to 60 Gy/35 fractions/5 wk. During radiation treatment, paclitaxel (60 mg/m(2)) was given as a 1-h infusion once weekly for 5 wk. Twenty-four patients were enrolled in the study. Hematologic toxicities and alopecia were the major acute toxicities during induction chemotherapy; 8.7% of the patients experienced grade 3-4 neutropenia and alopecia. The main acute toxicity of concurrent chemoradiotherapy was esophagitis; grade 3 esophagitis was documented in 23.5% of the patients. No major late toxicity was seen. Overall response rate to the treatment was 65.2%. The median and 1-yr overall-survival rates were 24.9 mo and 63.8%, respectively. The median and 1-yr progression-free survival rates were 9.0 mo and 27.8%, respectively. The main acute toxicities were hematologic toxicity, esophagitis, and alopecia. The response rate and the survival rates achieved with this treatment regimen are particularly noteworthy, especially considering the advanced stage of the patients treated.
