Purpose: This phase II study evaluated the feasibility and efficacy of one cycle of induction chemotherapy, followed by concurrent chemoradiotherapy (CRT) featuring capecitabine/cisplatin, followed in turn by surgery, in the treatment of patients with resectable esophageal squamous cell carcinoma.
Methods: Between March 2003 and April 2005, 54 patients with stage II or III esophageal cancer were treated with induction chemotherapy (cisplatin 60 mg/m(2) on day 1; capecitabine 1,000 mg/m(2) bid on days 1-14) followed by concurrent radiotherapy (46 Gy in 23 fractions) and chemotherapy (cisplatin 30 mg/m(2) on days 1, 8, 15, and 22; capecitabine 800 mg/m(2) bid 5 days/week). Surgery was performed within 8 weeks of the end of radiotherapy.
Results: Median age of the patients was 64.5 years (range, 45-74 years). After CRT, 52 patients (96%) showed a clinical response, including 26 (48%) who exhibited a complete response (CR). Surgery was performed on 41 patients (76%), with 20 (37%) achieving pathologic CR and 3 (6%) dying of postoperative pneumonia. At a median follow-up time of 74.2 months (range, 64.3-84.8 months), 16 patients (30%) had experienced tumor recurrence and 36 (67%) had died. Of the 41 patients who underwent esophagectomy, 5 (12%) had exclusively locoregional disease and 7 (17%) had distant metastasis, whereas no one had both. The 5-year progression-free and overall survival rates were 30.2% (95% confidence interval [CI], 18.0-42.4%) and 37.0% (95% CI, 24.1-50.0%), respectively.
Conclusions: A trimodal approach, consisting of a single cycle of induction chemotherapy, CRT containing capecitabine and cisplatin, and surgery, was feasible and effective in patients with resectable esophageal squamous cell carcinoma.
