    Abstract:
    The purpose of this study was to determine the toxicity and efficacy of single daily fractionation as compared with twice-a-day radiation therapy in combination with chemotherapy for preoperative locally advanced thoracic esophageal carcinoma. A retrospective survey was done of 42 patients undergoing concurrent chemotherapy and radiation for preoperative locally advanced thoracic esophageal carcinoma. Twenty-five patients had 5-fluorouracil ([5-FU]), 1,000 mg/m2/d by continuous infusion, days 1-5, and days 22-26), cisplatin (100 mg/m2 intravenously, days 2 and 22), and radiation to a total dose of 4,500 to 5,040 cGy in 180 cGy/fraction every day. Seventeen patients received 5-FU (300 mg/m2/d by continuous infusion, days 1 and 21), cisplatin (20 mg/m2/d for 1 hour, days 1-5 and days 17-20), vinblastine (1 mg/m2 intravenously, days 1-5 and days 17-21) and accelerated hyperfractionated radiation 150 cGy twice a day to a total dose of 4,500 cGy. Response rate, survival, local regional failure rates, and treatment toxicity of the two groups were compared. Surgery was aborted in one patient and another patient refused surgery in the single daily-fractionation group. All patients underwent surgery in the twice-daily group. Complete response (CR) was noted in 12 patients (52%) in the single daily-fractionation group as compared with 9 patients (52%) in the twice-daily group. The median and 3-year survival were 20 months and 35%, respectively, in the single daily-fractionation group. Corresponding figures were 18 months and 32%, respectively, in the twice-daily group. For the 2 groups combined, a statistically significant improvement in survival was observed among blacks who achieved a CR (31 months) as compared with the ones with residual disease (13.5 months). Local and regional failures were 28% and 17%, respectively, for the single daily-fractionation and twice-daily groups. Distant metastases remained significant in both groups and were 36% (single daily-fractionation) and 41% (twice-daily), respectively. Grades III to IV esophagitis and hematologic toxicity developed in 36% and 64% of patients of the single daily-fractionation and twice-daily groups, respectively. The incidence of late complications was 16% (single daily-fractionation) and 11.7% (twice-daily). Preoperative chemotherapy and radiation is effective to achieve a high pathologic CR. Both radiation therapy fractionation schedules are comparable in efficacy and toxicity. Further investigations should be done to assess whether ethnicity may play a role in the prognosis of esophageal carcinoma.
