Abstract
Introduction: Ovarian metastases from gastrointestinal cancers (Krukenberg tumors) are rare, accounting for 1–2% of all ovarian malignancies. Despite their low incidence, they pose substaintial diagnostic and therapeutic challenges. This study evaluates the clinicopathologic features, molecular profile, treatment strategies, and outcomes of patients with Krukenberg tumors. Methods: Between January 2023 and December 2024, we analyzed 12 ladies diagnosed with Krukenberg tumors of gastrointestinal origin. demographics, tumor characteristics, molecular markers, treatment modalities, and survival outcomes reviewed. Progression-free survival (PFS) and overall survival (OS) were calculated across treatment lines. Our ethical committee approved this study. Results: Primary tumors were colorectal (n=7) and gastric (n=5). Median age was 43 years; five patients were premenopausal. Six had synchronous and six had metachronous ovarian metastases. All tumors were pMMR with low TMB; KRAS mutations were present in 50% of cases, HER2 positivity was observed in one case, and BRAF was wild type in all. Four patients underwent ovarian metastasectomy. Median PFS1, PFS2, and PFS3 were 4.56, 2.13, and 3.3 months, respectively. At two years, 45.5% were alive, 75% of those who had metastasectomy. Conclusion: Krukenberg tumors often affect younger women and exhibit poor response to treatment. Ovarian metastasectomy may improve survival when metastases are isolated. Further research into their immune microenvironment is warranted.
