Prospective evaluation of preoperative chemotherapy in resectable squamous cell carcinoma of the thoracic esophagus.
A prospective study was performed to clarify the surgical outcome of patients with esophageal carcinoma who would benefit from induction chemotherapy followed by surgery. Of 55 eligible patients, 42 (76.3%) agreed to randomization with either chemotherapy followed by surgery (n = 21) or surgery alone (n = 21). The other 13 refused. The chemotherapy consisted of cisplatin, 5-fluorouracil and leucovorin. All 55 patients underwent esophagectomy with two- or three-field resection, including two (3.6%) hospital mortalities. Of the 21 patients receiving chemotherapy, the response rate was 33.3% after the first course and 60% after the second course. A complete response was not obtained. Responders to the first course showed a prolonged survival, however time to treatment failure did not differ between patients treated with chemotherapy followed by surgery or surgery alone. This chemotherapy offered a worse surgical outcome for patients with pretreatment diagnosis of T3. Multivariate analysis identified a partial response to the first course of chemotherapy to be a favorable prognostic indicator. Preoperative chemotherapy does not give a survival benefit over surgery alone for patients with advanced tumor (T3). Initial response to the first dose of chemotherapy is deemed to be a prognostic factor for patients with less advanced tumor (T1/T2).
