Phase III Study of Concurrent Radiotherapy in Elderly Patients With Esophageal Squamous Cell Carcinoma (ESO-Shanghai 15)

So far, there is no specific clinical guideline for elderly patients (\>75 yr) with esophageal squamous cell carcinoma (ESCC). Patients with locally advanced ESCC were enrolled and randomly assigned to either definitive radiotherapy group (61.2Gy/34Fx） or the chemoradiotherapy group (50.4Gy/28Fx；Paclitaxel plus carboplatin). The primary end point was 3-year overall survival (OS). The second end points included life quality, radiation side effects and 3-yr cancer specific survival.
