ABSTRACT
INTRODUCTION:
Ovarian metastases from gastrointestinal cancers such as colorectal cancer, also known as Krukenberg tumors (KTs), present unique challenges in management due to diagnostic uncertainty, decreased responsiveness to systemic therapies compared to other sites of metastasis, and associated debilitating symptomatology. Thus, we sought to characterize our institutional outcomes in metastatic colorectal cancer (mCRC) patients with KTs.METHODS:
A retrospective single-institution study was performed identifying adult, female patients from 2012 to 2021 with a diagnosis of mCRC. Patient demographics and clinicopathologic characteristics were collected and analyzed. Descriptive statistics, univariate and multivariable analyses, and Kaplan-Meier survival analyses were performed.RESULTS:
Of 235 mCRC patients, 45 (19.1%) had KTs, 41 (91.1%) of whom had KTs in conjunction with other metastatic sites. Other initial sites of metastasis included the liver (n = 93, 39.6%), lung (n = 28, 11.9%), and peritoneum (n = 18, 7.7%). In the KT cohort, the median age was 48 y, 53.3% were non-Hispanic White, 100% had microsatellite stable tumors, 33.3% had Kristen Rat Sarcoma Virus (KRAS) mutations, and 6.7% had V-raf Murine Sarcoma Viral Oncogene Homolog B (BRAF) mutations. Fifty five point six percent of KT patients underwent cytoreductive surgery (CRS), 24.4% underwent palliative debulking, and 20% underwent no surgical intervention. Reasons for not undergoing CRS were disease-related (n = 14, 70%), due to poor performance status (n = 1, 5%), or both (n = 5, 25%). Five-year overall survival was 48.2% in KT patients who underwent CRS. Poor tumor grade was an independent predictor of mortality (hazard ratio 10.69, 95% confidence interval 1.20-95.47, P = 0.03).CONCLUSIONS:
Almost 90% of our patient cohort with KTs from mCRC experience additional sites of metastasis. Around half of KT patients who underwent CRS were alive at 5 y.Key words
