Abstract 1634

Background

Third-generation regimens with chemoradiotherapy (CRT) has been established as one of a standard treatment for patients with unresectable stage III non-small cell lung cancer (NSCLC) after first results of the phase III WJTOG0105 trial. However, the long-term survival and cumulative incidences of toxicity associated with CRT remains unclear. We report survival and late toxicities with a follow-up period of 10 years.

Methods

Eligible patients were randomly assigned to A (control), four cycles of mitomycin (8 mg/m2 on day 1)/vindesine (3 mg/m2 on days 1, 8)/cisplatin (80 mg/m2 on day 1) plus thoracic radiotherapy (TRT) 60 Gy; B, weekly irinotecan (20 mg/m2)/carboplatin (area under the plasma concentration-time curve [AUC] 2) for 6 weeks plus TRT 60 Gy, followed by two courses of irinotecan (50 mg/m2 on days1, 8)/carboplatin (AUC 5 on day1); C, weekly paclitaxel (40mg/m2)/carboplatin (AUC 2) for 6 weeks plus TRT 60 Gy, followed by two courses of paclitaxel (200mg/m2 on day1)/carboplatin (AUC 5 on day 1). Kaplan-Meier survival curves and 5- and 10-year survival probabilities were calculated. Late toxicities were defined as occurring later than 90 days after CRT initiation.

Results

From September 2001 to September 2005, 440 patients (arm A, n = 146; arm B arm, n = 147; arm C, n = 147) were enrolled. In the arm A, B and arm C, median overall survival (OS) time was 20.5, 19.8 and 22.0 months, 5-year survival probability was 20.9%, 16.0% and 18.2%, and 10-year survival probability was 13.6%, 7.5% and 15.2%, respectively. There were no significant differences in OS among the treatment arms. The 10-year progression-free survival (PFS) probability was 8.5%, 6.5%, and 11.1% in arm A, B and C. %Grade 3/4 late toxicities were 3.4% (heart 0.7%, lung 2.7%) in arm A and only lung 3.4% in arm B and lung 4.1% in arm C. No additional cases of late toxicity (Grade 3/4) were seen since the initial report.

Conclusions

Arm C shows similar efficacy and toxicity profiles compared with arm A, even 10 years after starting treatment. However, 10-year PFS probability was only 11%, and thus new treatment strategies incorporating immunotherapy are required.
