      Background
      Chemotherapy-induced nausea and vomiting (CINV) is one of the major causes to deteriorate patient’s quality of life. Therefore, it is important to assess the current status of CINV nationwide for the appropriate treatment method to manage CINV. For this purpose, prospective multi-center observational study was performed in Japan.

      Methods
      Between 2011/Apr and 2012/Dec, 458 lung cancer patients who underwent systemic chemotherapy with high (HEC) or moderate emetogenic agents (MEC) were registered and the data in 429 patients were analyzed. CINV status was assessed in acute phase (within 24 hours from chemotherapy start) and late phase (after 24 hours) separately. Multivariate analysis was performed to clear the predictive factors in patient background for CINV.

      Results
      Patient background was as follows; median age 65, 318 male and 111 female patients, 190 patients treated with HEC and 239 with MEC. In acute phase, nausea and vomiting were observed in 5.6% (HEC 6.8%, MEC 4.6%) and 1.2 % (HEC 0.5%, MEC 1.7%) of all patients, respectively. In late phase, nausea and vomiting were observed in 40.1% (HEC 46.3%, MEC 35.2%) and 9.6 % (HEC 7.9%, MEC 10.9%) of all patients, respectively. The frequency of nausea in late phase is significantly higher in HEC than that in MEC. The predictive factors for nausea were a younger age in female patients, and younger age, no drinking history, decreased hemoglobin in male patients. The prediction of CINV by physician was relatively poor in late phase vomiting.

      Conclusion
      In this study, the current status of CINV and antiemetic therapy in lung cancer patients in Japan were elucidated. CINV was frequently observed in late phase and the appropriate management for late emesis is needed according to the guideline.

      O15.05 - Randomized Phase III Trial of S-1 plus Cisplatin versus Docetaxel plus Cisplatin for Advanced Non-Small-Cell Lung Cancer (TCOG0701): Subgroup Analysis. (ID 1895)

      Background
      Docetaxel plus cisplatin (DP) is the only third-generation regimen that has demonstrated statistically significant improvements in overall survival and QOL by head-to-head comparison with a second-generation regimen (vindesine plus cisplatin) in patients with advanced non-small cell lung cancer (NSCLC). S-1 plus cisplatin (SP) has shown activity and good tolerability in phase II settings. Molecularly targeted agents including bevacizumab (BEV) have shown activity and safety in non-squamous (non-Sq) NSCLC.

      Methods
      Patients with previously untreated stage IIIB or IV NSCLC, an ECOG PS of 0-1 and adequate organ functions were randomly assigned to receive either oral S-1 80 mg/m[2]/day (40 mg/m[2] b.i.d.) on days 1 to 21 plus cisplatin 60 mg/m[2] on day 8 every 5 weeks or docetaxel 60 mg/m[2 ]on day 1 plus cisplatin 80 mg/m[2] on day 1 every 3 weeks, both up to 6 cycles. The primary endpoint was overall survival (OS). A non-inferiority study design was employed; the upper confidence interval (CI) limit of the hazard ratio (HR) was <1.322. Secondary endpoints included progression-free survival (PFS), response, safety, and QOL. Subgroup analysis by histology (non-Sq vs Sq) was conducted.

      Results
      From April 2007 through December 2008, 608 patients were randomly assigned to SP (n=303) or DP (n=305) at 66 sites in Japan. Patient demographics were well balanced between the two groups. Non-Sq and Sq patients in SP/DP arm was 251/247 and 50/48 respectively. Two interim analyses were preplanned. At the final analysis, a total of 480 deaths had occurred. The primary endpoint was met. OS in the SP arm was non-inferior to that in the DP arm (median survival, 16.1 vs. 17.1 months, respectively; HR=1.013; 96.4% confidence interval, 0.837-1.227). PFS was 4.9 months in the SP arm and 5.2 months in the DP arm. The rates of febrile neutropenia (7.4% vs. 1.0%), grade 3/4 neutropenia (73.4% vs. 22.9%), grade 3/4 infection (14.5% vs. 5.3%), and grade 1/2 alopecia (59.3% vs. 12.3%) were significantly lower in the SP arm than in the DP arm. In terms of physical functioning and global functioning on the EORTC QLQ-C30 and lung cancer module (LC-13), QOL was better in the SP arm (repeated measures ANOVA: p<0.01). Subgroup analysis by histology revealed that the median OS of non-Sq and Sq patients in SP/DP group was 17.4/19.1 months and 12.3/11.7 months respectively, of which hazard ratio was 0.973 (95% CI, 0.797-1.187) and 1.239 (95% CI, 0.819-1.874). Interaction P value was 0.3004.

      Conclusion
      S-1 plus cisplatin is a standard first-line chemotherapeutic regimen for advanced NSCLC both non-Sq and Sq histology. Favorable toxicity profile of the SP regimen and encouraging outcome in patients with non-Sq prompted us to conduct a prospective study of SP plus BEV and maintenance S-1 BEV for non-SQ currently underway.
