PURPOSE: To evaluate the value of lymphatic vessel invasion (LVI) as a predictor of survival in patients with primary resected adenocarcinomas of the esophagogastric junction (AEG).
PATIENTS AND METHODS: We prospectively evaluated 459 patients undergoing primary surgical resection for tumors of the esophagogastric junction at our institution between 1992 and 2000 (180 adenocarcinomas of the distal esophagus, AEG I; 140 carcinomas of the cardia, AEG II; and 139 subcardial gastric cancers, AEG III). Median follow-up was 36.8 months. The prevalence of LVI was evaluated by two independent pathologists. Univariate and multivariate analysis of prognostic factors was performed.
RESULTS: The total rate of LVI was 49.9%, with a significant difference between AEG I (38.9%) and AEGII/III (57.0%, P = .0002). Univariate analysis showed a significant correlation between LVI and T category (P < .0001), N category (P < .0001), and resection status (R [residual tumor] category; P < .0001). This was shown for the group of all AEG tumors, as well as for the subgroups AEG I and AEG II/III. On multivariate analysis, LVI was identified as a significant and independent prognostic factor (P = .050) in the population of all patients and in patients with AEG II/III, but not in the subgroup with AEG I.
CONCLUSION: These data demonstrate the prognostic significance of LVI in patients with AEG tumors, with marked differences between the subgroups AEG I versus AEG II/III. The lower prevalence and lack of prognostic significance of LVI in AEG I might be explained by inflammation involved in the pathogenesis of this entity.
