Abstract
Objectives
The aim of this study was to evaluate the efficacy of adjuvant chemoradiotherapy following surgery in patients with advanced esophageal cancer.
Subjects and Methods
We followed the cases of 57 such patients treated at our hospital, involving 19 who received adjuvant chemoradiotherapy (CR group), 19 who received radiotherapy alone (R group), and 19 who did received neither (N group). In the CR group, chemotherapy, consisting of cis-diaminodichloroplatinum (CDDP), 5-fluorouracil (5-FU), and etoposide (VP-16), was combined with radiotherapy was administered from 4 weeks after surgery. Concurrent radiotherapy was started at 3 weeks after esophagectomy. CDDP at 50 mg/m2 was administered on days 1 and 7. 5-FU at 500 mg/m2 and VP-16 at 60 mg/m2 were administered on days 3, 4, and 5. Thirteen patients (68.4%) were treated with more than 2 cycles of chemotherapy combined with radiation.
Results
Side-effects of severe anorexia (grade 3) and leukocytopenia (<1900/μl) were observed in 47% and 39% of the patients, respectively. However no treatment-related death was observed. The 5-year-survival rate was 25.2%, 18.9%, and 15.8%, in the CR group, R group, and N group, respectively. The recurrence rate was 66.7% in the CR group, which was higher than in the matched control groups (46.2% in the N group and 54.5% in the R group), but with no a significant difference.
Conclusion
These results suggested that adjuvant chemoradiotherapy did not contribute to improvement in prognosis for these patients with advanced esophageal cancer.
