Krukenberg tumors of gastric origin versus Krukenberg tumors of colorectal origin

Abstract

The aim of this study was to analyze the incidence and origin of Krukenberg tumors in our region to determine their clinical behavior and to compare some anatomo-clinical features of Krukenberg tumors of gastric origin versus those of colorectal origin. This is a retrospective, descriptive and comparative study of Krukenberg tumors diagnosed and treated in the IV-th Surgical Clinic of Cluj-Napoca. The epidemiologic features concerning global incidence, age, and menopausal status overlap the data from literature. Characteristic for our series of cases were the higher incidence of Krukenberg tumor of colorectal origin compared with those of gastric origin , significantly more frequent bilaterality of lesions of gastric origin and the prevalence of the unilateral left ovarian localization for Krukenberg tumors of colorectal origin. The differences in anatomo-clinical behavior between the Krukenberg tumors of gastric and colorectal origin may indicate different pathways of metastasizing and seeding.
