title: The long-term results of pre-operative hyperthermo-chemo-radiotherapy for oesophageal carcinoma--a comparison with preoperative radiation therapy alone.
abstract: The long-term results of patients with oesophageal carcinoma treated with pre-operative hyperthermo-chemo-radiotherapy (HCR) and pre-operative radiation therapy alone were compared. Twenty-six patients treated with pre-operative hyperthermo-chemo-radiotherapy (HCR Group) and 25 treated with radiation therapy alone (R Group), which demonstrated histopathologically marked effective results (Grade 3), were entered into the study. The 3-year survival rates after oesophagectomy in the HCR Group and the R Group were 67.4% and 41.8%, respectively, while the 5-year survival rates were 50.5% and 34.9%, respectively. Thus post-operative prognosis in the HCR Group was significantly more favourable than that in the R Group (P < 0.05). The local recurrence and distant metastasis rate in the HCR Group was significantly less than in the R Group (P < 0.01). This significant difference in prognosis was thought to be due to the reinforced effects of local regulation by hyperthermia and the systemic control of micrometastasis by chemotherapy in addition to radiation. Our data suggest that for carcinoma of oesophagus, pre-operative hyperthermo-chemo-radiotherapy contributes to prolonged post-operative survival while reducing both local recurrence and micrometastasis.
