Abstract Background Definitive radiotherapy plus concurrent chemotherapy has been a standard treatment for esophagus patients who are unfit to undergo surgery. However, there are a variety of concurrent chemotherapy regimens with varying efficacy. In this phase II prospective study, we compared the efficacy and toxicity of DP (docetaxel and cisplatin) and PF (cisplatin and 5-fluorouracil) regimens with concurrent chemoradiotherapy (CCRT) in patients with esophageal squamous cell carcinoma (ESCC) and analyzed the 5-year overall survival (OS) and progression free survival (PFS). We also summarized the salvage treatments and late toxicities. Methods We enrolled 86 patients with clinical stage II-IVA from the Sun Yat-sen University Cancer Center. The patients were divided into two groups: PF group (41) and DP group (45). Statistics were analyzed using SPSS version 19.0. Results The 5-year OS rates were 62.9% ± 7.6% in PF group, and 52.7% ± 7.5% in DP group (P = 0.131), respectively. The 5-year PFS rates were 43.9% ± 7.8% for PF group, and 40.0% ± 7.3% for DP group (P = 0.398), respectively. Sixteen patients in the DP group and thirteen in the PF group received salvage treatment. For those patients with local residual or local recurrent disease, the median survival time after salvage treatment was 13.5 months and the 1, 2, and 3-year survival rates were 79.0%, 50.3%, and 43.1%, respectively. For all patients, thirteen (15.1%) had Grade 2 late cardiac toxicities. One patient had Grade 2 pleural effusion and required diuretic. Most patients with pneumonia are mild, and only one patient in PF group had Grade 2 pneumonia. One patient in the DP group developed tracheoesophageal fistula. Conclusions The 5-year follow-up confirmed that definitive CCRT with the DP regimen did not improve the treatment response, OS, or PFS in patients with ESCC compared to the PF regimen. The PF regimen remains the standard regimen for definitive CCRT for patients with locally advanced ESCC. Long-term follow-up also suggested that appropriate and active salvage treatment has a survival benefit for some patients, and late cardiopulmonary toxicities should be noticed during follow-up. Trial registration The trial was registered at https://clinicaltrials.gov (ClinicalTrials.gov Identifier: NCT 02969473, October 2010). |
