Abstract
We performed this study to examine the prevalence of tumor deposits (TD) in gastric adenocarcinomas (GACa), and the relevance of their presence, size and type to clinical outcome.Ninety-six patients, histopathologically diagnosed as GACa following a total/subtotal gastrectomy were included, and clinicopathologic data were recorded.Due to the statistical analysis, the majority of TD(+) cases were of intestinal type and showed vascular invasion. In these cases, the incidence of local recurrence was significantly higher. The majority of GACa of intestinal type with TD were of high grade and showed vascular invasion. Recurrence and death were more commonly encountered among them. The recurrence-free survival (RFS) was significantly shorter in patients with TDs, which was also confirmed by multivariate analysis, and there was a significant difference between both RFS and overall survival of TD(+) and TD(−) cases of intestinal type GACa.In conclusion, in this study, we demonstrate that TDs are not infrequently observed in GACa, they are more commonly associated with the intestinal type and vascular invasive gastric cancers. Our study shows the prognostic impact of TDs, especially regarding the RFS. Therefore, the documentation of TDs might be considered for prospective studies, especially for the intestinal type GACa, a shortcoming of this study.
