- Abstract: OBJECTIVE: The aim of this study is to compare the each clinical manifestation related with its mean survival time of Krukenberg tumors (KTs) of gastric origin versus with that of colorectal origin. METHODS: A total of 156 consecutive patients diagnosed with KTs of the ovary who underwent surgical treatment at a single institution between 2001 and 2010 were retrospectively evaluated. Each clinical manifestation related with its mean survival time compared two different groups. Survival analyses and comparisons were performed using the Kaplan-Meier method. RESULTS: Among the 156 patients with KT, 111 patients with KTs of gastric origin and 45 patients with KTs of colorectal origin were identified. For all patients with KTs, median survival time was 22.7 months. Each mean survival time among all patients with KTs of gastric origin and colorectal origin was 19.2 months and 27.3 months. The results showed that mean survival time of postmenopausal patients was 19.0 months compared with 32.5 months for premenopausal patients (P=0.015). Among all patients, mean survival time of those with metachronous cancer was longer than those with synchronous cancer (P=0.001). In all cases, especially when only one ovary was invaded, the mean survival time was relatively higher (P=0.001). CONCLUSION: Patients with KTs of colorectal origin had a better prognosis than those of gastric origin. In all cases of KT, the mean survival time was significantly longer in postmenoposal patients, metachronous disease and unilateral ovarian involvement. Notably, synchronous, ascites positive, and ovary only metastasis showed more longer mean survival time in the KTs of colorectal origin than KTs of gastric origin.
