    P2.09-014 - Concomitant Chemoradiotherapy Using Docetaxel and Cisplatin for Unresectable Stage III Lung Squamous Cell Carcinoma (ID 2846)

    • Abstract

    Background
    Concomitant chemoradiotherapy is the standard treatment of unresectable stage III non-small cell lung cancer (NSCLC). However, the optimal chemotherapy regimen is still controversial, particularly in lung squamous cell carcinoma. We have conducted a phase II clinical trial in a Chinese population to evaluate concomitant treatment using docetaxel/cisplatin chemotherapy and thoracic radiotherapy followed by docetaxel/cisplatin consolidation chemotherapy in unresectable stage III lung squamous cell carcinoma. The purpose of this study is to evaluate the feasibility and activity, and also assess its impact on progression-free survival (PFS).

    Methods
    A total of 32 patients were enrolled between January 2011 and January 2013. Patients received concomitant docetaxel 30mg/m[2] on day 1 and day 8, cisplatin 25mg/m[2] on day 1 to day 3 repeated every 3 weeks for 2 cycles and thoracic radiotherapy, followed by docetaxel/cisplatin for 2 cycles as consolidation therapy (docetaxel 60mg/m[2] on day 1, cisplatin 25mg/m[2] on day 1 to day 3 repeated every 3 weeks). Objective response rate according to the RECIST criteria was recorded and toxicity was evaluated using the NCI Common Toxicity Criteria. The Kaplan–Meier method was used to evaluate patient survival. Univariate analysis of patient characteristics and tumor responses was conducted using the Chi-square and Fisher’s exact test.

    Results
    Eight (25.0%) and 20 patients (62.5%) had a complete or partial response, respectively, while 3 patient’s disease remained stable and 1 patient had progression of the disease. The overall response rate (87.2%, 95% confidence interval (CI): 63–97%) exceeded the goal per study design. The median PFS was 11.0 months (95% CI: 5.6–16.4 months). This approach obtained likely better effects than history control group. Main toxicity (grade 3 or greater, %): neutropenia 10 (31.3%); thrombocytopenia 7 (21.9%); anaemia 8 (25.0%); nausea/vomiting 5 (15.6%); anorexia 7 (21.9%), dysphagia 4 (12.5%), radiation pneumonitis 3 (9.4%) and fatigue 4 (12.5%).

    Conclusion
    This data suggests that concomitant treatment with docetaxel/cisplatin and thoracic radiotherapy was well tolerated, with promising activity in a Chinese population with unresectable stage III lung squamous cell carcinoma. Although the data presented herewith appears promising, this study is relatively small, and more data from randomized trials are needed to further validate this regimen.
