Preoperative concomitant radiochemotherapy in squamous cell carcinoma of the esophagus: results of a study of 56 patients.
OBJECTIVE
Today the prognosis for patients with esophageal carcinoma still remains quite poor. In the last few years interesting results have been obtained by associating radio- and chemotherapy with or without surgery with this type of cancer. In this work we report the results of concomitant radio- and chemotherapy in a split-course schedule preceeding surgery for the treatment of squamous cell carcinomas of the esophagus.


METHODS
Fifty-six patients with squamous cell carcinomas of the esophagus were treated between April 1989 and September 1993 in the Centre Hospitalier Universitaire in Brest, France with two courses of preoperative concomitant radiochemotherapy, separated by a 2-week interval, and followed by surgery (each course 18.5 Gy in five fractions, days 1-5 with continuous infusion 5-fluorouracil (5-FU) 800 mg/m2 days 1-5 and cisplatinum 70 mg/m2 day 2). Patients who had responded well to preoperative treatment (response > 50%) received four more courses of chemotherapy alone. The two patients who were not operated and those with palliative surgery received a third course of radiochemotherapy (radiotherapy 12 Gy in five fractions, days 1-5).


RESULTS
Fifty-four patients were operated on. Twenty-one showed histological complete response at surgery (37.5% of the whole group). Actuarial survival for the 56 patients was 55% at 3 years and 30% at 4 years, with a median survival of 37.4 months (40.4 months for complete responders to preoperative treatment). Toxicity of preoperative concomitant radio-chemotherapy was low (5-FU had to be stopped in one patient because of cardiac rythm disturbances and in another patient because of aplasia Grade 4 associated with infection after the first course). Postoperative mortality was 11% (six patients).


CONCLUSIONS
This combination of preoperative radiochemotherapy followed by surgery seems to improve both response rates and survival in patients with esophageal cancer when compared with previous patients treated with surgery alone in our hospital or with results found in literature and it warrants further studies.
