 A phase II study of radical radiotherapy with IMRT simultaneous integrated boost technique and concurrent chemotherapy for esophageal carcinoma use the same radiation dose as the high dose arm in RTOG 94-05, which reveals an significantly improved median survival time of 23 months and 3-year overall survival rate of 44.4. This study implies the simultaneous integrated boost technique may be effective to some extent. But the question is how to identify patients who may gain potential benefits, and whether this therapeutic model can be copied in the specific situation in China? Few adverse effects such as perforation, hemorrhage and stenosis was reported, mainly owing to the lack of cases. For widely application of this new technique in the clinic, more studies need to be conducted in the future to obtain sufficient evidence.
