Preoperative hyperthermo-chemo-radiotherapy (HCR) has been performed on patients with esophageal carcinoma, especially in advanced cases with invasion to the neighbouring structures (a3 carcinoma), and is considered to ftave contributed to the favorable postoperative prognosis. 163 patients with operated locally advanced esophageal carcinoma with invasion to the neighbouring structures (a3 carcinoma) were analyzed. 40 cases were treated with preoperative HCR (HCR group), while 85 cases were treated with other preoperative adjuvant therapies including 35 with chemo-radiotherapy (CR group) and 42 with radiotherapy (R group), and the remaining 38 were operated on without any preoperative treatments. The effectiveness of the therapies and the prognosis were investigated. The survival rates of the HCR group were significantly better than those of the CR group (p<0.05). The prognosis of cases with Grade 3 effectiveness was significantly better than those of others, moreover, in 5 cases with Grade 3 effectiveness in the HCR group, there was no case of early recurrence or metastasis after resection, while in addition, three patients have since survived for 4, 5, and 7 years, respectively. Our data showed that for the patients with locally advanced esophageal carcinoma with invasion to the neighbouring structures (a3 carcinoma), hyperthermia combined with chemotherapy and irradiation has demonstrated a favorable influence on the prognosis.
