Cancerous esophageal stenosis encountered during endoscopic ultrasonography before treatment was observed in about 30% of esophageal cancer patients. Since the pT stage in TNM classification measures only the depth of infiltration but not the growth to esophagus, it is interesting to know whether tumor growth into the esophagus (and eventual stenosis) is of added value in prognostic assessment. However, the impact of esophageal stenosis on survival of esophageal cancer patient remains unclear. Therefore, we conducted a meta-analysis focusing on current topic for the first time.
