摘要
Background. To assess the long-term efficacy and the pattern of failure of concurrent chemoradiotherapy followed by high dose rate (HDR) brachytherapy for stage T2-3 N0-1 M0 esophageal carcinoma. Methods. Forty-six patients with clinical stage T2-3 N0-1 M0 esophageal cancer received concurrent chemoradiotherapy followed by HDR brachytherapy. The chemotherapy regimen was a combination of cisplatin 60 mg/m2 on day 1 and fluorouracil 600 mg/m2 continuous infusion from days 1 to 4 during the first and last week of external-beam irradiation. Radiotherapy consisted of external beam to a total dose of 40-60 Gy (median, 50 Gy) and high dose rate brachytherapy to 8-24 Gy (median, 16 Gy) in 2-4 fractions. External beam was delivered to a field of the primary lesion and the involved nodal lesions. All patients were followed up for at least 5 years. Results. The 5-year overall survival rate was 28%. The median survival duration was 22 months. The 5-year cause-specific survival rate was 34% and the median was 22 months. Persistent disease was found in 7 of 46 patients (15%). Of the 39 patients with initial complete tumor disappearance, locoregional failure occurred ultimately in 13 patients. The ultimate local control rate was 57% (26/46). Three patients were salvaged successfully with surgery. Four patients (9%) had regional recurrence out of the irradiated fields as first failure site. Four patients (9%) had recurrence 3 years or longer after treatment. Twelve patients had transient ulcers, which healed spontaneously within a few months. Massive esophageal bleeding, thought to be treatment related, occurred in 2 patients, leading to death. Severe late toxicity with esophageal ulceration was found in patients receiving a dose of 16-24 Gy via brachytherapy. Conclusions. Concurrent chemoradiotherapy followed by HDR brachytherapy achieved long-term effective and curative results for stage T2-3 N0-1 M0 esophageal carcinoma. However, severe late toxicity was observed with 16-24 Gy via brachytherapy. We recommend a dose via HDR brachytherapy should be 12 Gy or less following concurrent chemoradiotherapy. © Japan Esophageal Society and Springer-Verlag 2006.
