MINI07.01 - A Randomized Phase II Study of S-1 and Cisplatin vs Vinorelbine and Cisplatin with Concurrent Radiotherapy for Locally Advanced NSCLC: WJOG5008L (ID 544)

Background:
Cisplatin-based chemotherapy and concurrent radiotherapy is the standard treatments for locally advanced non-small cell lung cancer ( LA-NSCLC). This trial evaluated two experimental regimens of chemotherapy with concurrent radiotherapy.
Methods:
Eligible patients (pts) with unresectable stage III NSCLC, 20 to 74 years of age, and ECOG PS of 0–1 were randomized to either Arm SP, S-1 (40 mg/m[2]/dose per oral, b.i.d, on days 1-14) and cisplatin (60 mg/m[2] on day 1) repeated every 4 weeks or Arm VP, vinorelbine ( 20mg/m[2] on day 1, 8) and cisplatin (80 mg/m[2] on day) repeated every 4 weeks with early concurrent thoracic radiotherapy of 60Gy at 2 Gy per daily fraction. The primary endpoint was overall survival rate at 2-year (2yr-OS). A pick-the-winner design was used to identify the treatment regimen most likely to be superior. The planned sample size was 55 patients per arm, assuming in each arm that the null hypothesis for 2yr- OS was 50% versus an alternative hypothesis for 65% with one-sided alpha of 0.10 and power of 80%. All the radiation treatment plans were reviewed at quality assurance committee meetings. (Study ID: UMIN000002420)
Results:
One hundred eleven patients were registered between Sep 2009 and Sep 2012. Of 108 patients for efficacy analysis, the 2yr-OS was 76% (95% CI, 62-85%) for SP and 69% (95% CI, 54-79%) for VP. The hazard ratio (HR) of death between the two arms was 0.85 (0.48-1.49). The median progression-free survival (PFS) was 14.8 months for SP and 12.3 months for VP with a HR of 0.92 (0.58-1.44). 80% and 48% of pts completed the protocol treatment in SP and VP, respectively. Common grade 3-4 toxicities of both SP and VP were neutropenia 33%, 75%, platelets 9%, 4%, hemoglobin 26%, 28%, febrile neutropenia 9%, 17%, diarrhea 6%, 0% respectively. There were 4 and 5 treatment-related deaths in Arms SP and VP, respectively. The quality assurance committee judged that 74% of radiation treatment plans had no deviation and 24% had a minor deviation.
Conclusion:
Both arms rejected the null hypothesis for 2yr-OS. In this study Arm SP was declared the winner in terms of 2yr-OS, PFS, treatment completion, and toxicity.

P2.01-059 - Does Pemetrexed/Platinum Fit All Patients with Non-Squamous Non-Small Cell Lung Cancer? A Retrospective Study of Clinical Factors and Outcomes (ID 2308)
09:30 - 17:00 | Author(s): J. Shimizu
- Abstract
Background:
Pemetrexed/platinum is one of the standard treatment regimens for patients with advanced non-squamous non-small cell lung cancer(NSCLC). The aim of this study was to examine the association between survival of lung cancer patients treated with pemetrexed/platinum and clinical factors.
Methods:
The medical records of advanced or relapsed non-squamous NSCLC patients treated with pemetrexed/platinum at our hospital between January 2010 and December 2013 were reviewed. Basic characteristics, histological subtypes of NSCLC, driver mutation status, TTF1 staining status and status of treatment with taxane were evaluated for association with the survival from pemetrexed/platinum started day to deaths.
Results:
Two hundreds nine records were reviewed. The median age was 62 (28-79), 60% were male, 40% were never smoker, 89% had an ECOG PS0-1 and 11% had a PS 2-3. The median value of CEA and CYFRA were 10.5 ng/ml and 3.0 ng/ml, respectively. 93% were diagnosed as adenocarcinoma and 7% were diagnosed as other subtypes (large, adenosquamous, sarcomatoid and not otherwise specified). 79% (81/102) had a positive TTF1 staining. 26% had EGFR mutation, 7% had ALK fusion and 11% had KRAS mutation. 36% of patients were received bevacizumab with pemetrexed/platinum. 35% of patients were treated with cisplatin. The response rate of pemetrexed/platinum was 34.8%. Median overall survival was 537days. 65% of patients were treated with taxane and the response rate was 15.0%. In multivariate analysis, poor PS(HR 1.33; p=0.027), others in histological subtypes (HR2.00; p=0.047) and K-RAS mutation(HR 2.74; p=0.021) correlated significantly with a shorter overall survival and low CYFRA(≤3.0ng/ml, HR 0.55; p=0.002) correlated significantly with a longer overall survival.
Conclusion:
High CYFRA, KRAS mutation and others in histological subtypes may be associated with shorter overall survival treated with pemetrexed/platinum in non-squamous NSCLC. The development of effective treatment regimens for such patients is needed to improve their outcomes.
