The clinicopathological characteristics, prognosis, and CT features of ovary metastasis from colorectal carcinoma

BACKGROUND: The aim of this study was to study patients diagnosed with ovary metastasis from colorectal carcinoma (OM-CRC) regarding their clinical manifestations, pathological characteristics and developments based on the results of computed tomography (CT). METHODS: Research was conducted with OM-CRC admissions to our facility during the period of January, 2000 to January, 2020, with examinations of both patients and imaging statistics. RESULTS: A group of 21 female participants with a median age of 54-year-old, ranging from 48 to 68 years old, were investigated. In the univariate analyses, synchronous metastasis and R2 resection (macroscopic residual lesions) during cytoreductive surgery (CRS) were shown to be negatively associated with the OM-CRC prognosis. Results of the multivariate analysis showed that R2 resection during CRS was the only independent predictor of the overall survival (OS) rate as well as the progression-free survival (PFS) rate. OM-CRC cases frequently exhibited a well-defined borderline (90.9%), predominantly cystic ovarian mass (90.9%), heterogeneous enhancement (72.3%), moderate enhancement (63.6%), peritoneal implantation (81.8%) and an absence of lymphadenopathy (90.9%). CONCLUSIONS: It is important to develop a thorough comprehension of the pathological characteristics as well as developments of OM-CRC, in order to understand its diagnosis, develop useful therapeutic interventions, and predict accurate prognosis. Nevertheless, OM-CRC is an uncommon malignant ovarian tumor and a good prognosis requires a CRS without macroscopic residual lesions, as a significant finding of our study.
