title: Clinical experience with radio-, chemo- and hyperthermotherapy combined trimodality on locally advanced esophageal cancer.
abstract: Esophageal cancer is a highly malignant and lethal disease with a low 5-year survival rate. Therefore, an effective treatment modality is required. To investigate the treatment efficacy and toxicity of radio-, chemo- and hyper-thermotherapy combined trimodality on locally advanced esophageal cancer, the medical records of 78 patients with pathologically confirmed esophageal cancer treated with chemoradiotherapy plus hyperthemia at our institution were retrospectively investigated and the 3-year outcome was carefully assessed. All 78 patients received intensity-modulated radiation therapy at a total dose of 60-66 Gy, in a conventional schedule of 1.8-2.1 Gy/fraction, 5 fractions/week. They also received 4-6 courses of chemotherapy, consisting of 450 mg/m25-fluorouracil for 1-5 days and 25 mg/m2cisplatin for 1-5 days, in addition to 6-12 sessions of hyperthermia, performed twice a week. Out of the 78 cases, complete remission of the primary tumor was observed in 31 (39.7%), partial remission in 44 (56.4%) and no change in 3 (3.9%) cases. The treatment response rate was 96.1%. The overall survival (OS) rate at 1, 2 and 3 years was 67.9, 41.0 and 33.3%, respectively. No significant difference in adverse effects was observed between this treatment regimen and other similar studies. Our preliminary results demonstrated that the chemo-, radio- and hyperthermotherapy combined trimodality exhibited excellent short-term clinical outcomes as regards tumor response rate and a sound long-term OS, with endurable adverse events. This trimodal treatment requires further investigation to establish its beneficial role in the treatment of patients with locally advanced esophageal cancer.
