ABSTRACT
Gastroesophageal junction (GEJ) neoplasms have become more common over the past decade. Like mediastinal and abdominal lymph nodes and other gastric tumors, GEJ tumors spread to the retroperitoneal nodes. The TNMI staging system does not consider this pattern and does not clinically distinguish GEJ tumors from gastric and esophageal cancers. The aim of the study is to compare the old and new TNM staging systems to assess whether the new TNM classifies lymph node involvement in these tumors as a prognostic factor. From January 1983 to December 1995, 438 patients underwent curative gastric resections for cancer at the Department of Surgery "P. Valdoni" of the University of Rome "La Sapienza." Sixty-two had GEJ type II and III tumors according to the Siewert classification system. The old pN1 and new /7NI survival rates (P < 0.05) were statistically different; the old pN2 and new pN2 survival rates (P = 0.483) were not. The multivariate analysis of significant statistical prognostic factors showed that the pTNM staging in type II and type III GEJ tumors is the most important prognostic factor (P < 0.001), followed by the old pN and new pN (P < 0.001) and the pT (P < 0.005). Gender, age, Lauren type, and tumor location according to Siewert (II vs III) were not independently significant prognostic factors. This study concludes that the numbers and locations of metastatic lymph nodes are important prognostic factors that should be included in the next TNM edition.
