Concurrent cisplatin and 5-fluorouracil versus concurrent cisplatin and docetaxel with radiotherapy for esophageal squamous cell carcinoma: a propensity score-matched analysis.

ABSTRACT: The optimal concurrent chemotherapy regimen with radiotherapy for esophageal cancer is unknown. Here, we compared the survival outcomes and toxicity of definitive chemoradiotherapy with either cisplatin/5-fluorouracil (PF) or docetaxel/cisplatin (DP) in patients with unresectable esophageal squamous cell carcinoma (ESCC). In this study, we identified 317 patients with ESCC who received PF or DP concurrently with definitive radiotherapy. PF group patients received two cycles of cisplatin (60 mg/m2) and 5-fluorouracil (300 mg/m2) at 4-week intervals during radiotherapy. DP group patients received a concurrent three-weekly schedule of docetaxel (60 mg/m2) and cisplatin (80 mg/m2) or cisplatin (25 mg/m2) and docetaxel (25 mg/m2) weekly. The overall survival (OS) and progression-free survival (PFS) were compared using propensity score (-adjusted, -weighted, -stratified, and -matched) analyses. A sensitivity analysis was performed to examine the impact of unmeasured confounders. Inverse probability of treatment weighting for propensity score demonstrated an improvement in OS and PFS with DP group in comparison with PF group (hazard ratio, 0.700; 95% CI, 0.577-0.851) and similar results were achieved with propensity score matching and stratification. Grade 3-4 esophagitis was more common (16/102 vs. 4/102) and grade 3-4 thrombopenia and skin toxicity were less common (3/102 vs. 10/102; 7/102 vs. 19/102; respectively) in the PF group than the DP group. In conclusion, concurrent chemoradiotherapy with the DP regimen resulted in better OS and PFS compared to concurrent PF regimen with tolerable toxicities in ESCC patients. Prospective randomized trials are required to confirm the efficacy of the DP regimen.

Project description:BACKGROUND:Promising efficacy and manageable toxicity of docetaxel-based concurrent chemoradiotherapy (CCRT) were reported in head and neck cancer. In addition, the effect of CCRT in combination with cisplatin and/or 5-fluorouracil on both locoregionally advanced and metastatic/recurrent nasopharyngeal carcinoma (NPC) was verified. However, CCRT with docetaxel for locoregionally advanced NPC are not well studied. This study aimed to compare effectiveness and toxicities of CCRT with weekly docetaxel versus tri-weekly cisplatin for locoregionally advanced NPC. METHODS:Clinical data of patients with locoregionally advanced NPC newly diagnosed between January 2010 and December 2014 receiving CCRT with either weekly docetaxel (15 mg/m2) or tri-weekly cisplatin (80-100 mg/m2) were reviewed. Propensity score matching at a 1:1 ratio was performed to balance baseline characteristics. Adverse events and survival were compared between the two groups. RESULTS:A total of 962 patients were included as the whole cohort, and 448 patients were matched and were regarded as the matched cohort. The median follow-up duration was 48 months for the whole cohort. The 3-year nodal recurrence-free survival rate was significantly increased for patients treated with docetaxel in both the whole (hazard ratio [HR] = 0.37, 95% confidence interval [CI] 0.19-0.72, P = 0.030) and matched cohorts (HR = 0.33, 95% CI 0.14-0.79, P = 0.023). However, no significant differences were observed in overall survival, local recurrence-free survival, and distant metastasis-free survival between the two groups in both cohorts. Significantly higher rates of grade 3 radiodermatitis (6.7% vs. 1.8%, P = 0.001), mucositis (74.5% vs. 37.9%, P < 0.001), and leucopenia (2.2% vs. 11.6%, P < 0.001) were observed in the docetaxel group, but any grade of renal injury (1.8% vs. 15.1%, P < 0.001), vomiting (18.8% vs. 88.3%, P < 0.001), and ALT elevation (19.2% vs. 31.3%, P = 0.027) were more common in the cisplatin group. CONCLUSIONS:CCRT with weekly low-dose docetaxel is an effective and tolerable therapeutic regimen for locally advanced NPC. It provides a survival benefit mainly by improving the control of regional lymph node metastases, especially for patients with low pretreatment EBV DNA levels.
