BACKGROUND/AIMS: To evaluate outcome of the U.S. RTOG/Intergroup Protocol 85-01 for 44 Japanese esophageal cancer patients. METHODOLOGY: Between 1996 and 2004, patients with esophageal cancer received the Intergroup concurrent chemoradiation therapy regimen for the primary treatment (n=44, group A). We compared the data with those of patients receiving radiotherapy (RT) combined with the weekly chemotherapy regimen (n=12, group B) and with those of patients receiving RT combined with the daily low-dose chemotherapy regimen (n=24, group C). RESULTS: The median survival period was 14.9 months in group A, 5.7 months in group B, and 6.3 months in group C. The survival rates at 1 and 3 years were 56% and 26% in group A, 42% and 21% in group B (p=0.3307), and 27% and 18% in group C (p=0.0462), respectively. CONCLUSIONS: The prognosis of patients who received the Intergroup regimen for esophageal cancer was significantly better than that of patients who received the daily low-dose chemotherapy regimen. The Intergroup regimen is well tolerable for the Japanese patients too.
