The aim of this study is to assess the effect of concomitant preoperative radio-chemotherapy in the treatment of epidermoid esophageal cancer.
We studied a total of 45 patients, divided into two groups. Group I consisted of 20 patients diagnosed with epidermoid esophageal cancer who had been treated initially with esophagectomy. Group II consisted of 25 patients treated with preoperative radiotherapy and two cycles of chemotherapy (cisplatin and 5-fluorouracil), one at the beginning and the other at the end of the radiation treatment, on whom an esophagectomy was subsequently performed. The clinical characteristics were similar in both groups. In group II, there were 12 cases (48%) with absence of tumor in the esophageal wall, three of which had node involvement. The operative mortality was similar in both groups (10% and 8% respectively).
The only significant difference found in the postoperative complications was the incidence of anastomotic leak; but this was related to the different esophagectomy techniques used rather than the type of therapy. A decrease in the number of patients with tumor recurrence was observed in Group II, especially where the local component was concerned.
The best actuarial survival rate at five years was in patients with no presence of tumor after neoadjuvant treatment (44.4%). However, the radio-chemotherapy seems not to have had any benefit in cases with node involvement.
