BackgroundAlthough a substantial proportion of patients undergoing neoadjuvant chemoradiation for invasive esophageal cancer develop a pathologic complete response (pCR), these patients nonetheless have a poor 5-year survival rate. We hypothesized that routine pathologic examination fails to identify some residual cancer.MethodsPatients undergoing esophagectomy for cancer at 2 tertiary care centers were identified. Archived tumor blocks were retrieved for patients with pCR, sectioned at 50-μm intervals and reexamined for residual cancer.ResultsSeventy patients underwent neoadjuvant chemoradiation. Tumor blocks were available for 23 of 26 complete responders. A total of 159 blocks were reexamined. One patient was found to have a possible focus of residual invasive adenocarcinoma versus high-grade dysplasia. The remaining 22 patients had no residual disease.ConclusionsA more aggressive examination protocol for postchemoradiation esophagectomy specimens may not result in significant upstaging. Inadequate pathologic examination is likely not a major factor in the suboptimal survival in patients with pCR.
