Krukenberg Tumors: Diagnostic Challenges, Treatment, and Survival Outcomes

Overview

This 16-year retrospective case series from a tertiary women's hospital in China analyzed 15 patients with Krukenberg tumors, highlighting diagnostic difficulties, treatment strategies, and survival outcomes. Most patients were premenopausal women presenting with nonspecific gynecological symptoms, and the tumors were often misdiagnosed preoperatively as primary ovarian neoplasms.

Background

Krukenberg tumors are rare ovarian metastases primarily originating from gastrointestinal tract cancers, especially gastric and colorectal primaries. They predominantly affect women of reproductive age and are characterized histologically by mucin-producing signet-ring cells. Due to their metastatic nature and nonspecific clinical presentation, diagnosis is challenging, and there are no standardized treatment guidelines. Prognosis remains poor, with median survival typically less than a year.

Data Highlights

Key Findings

• Krukenberg tumors predominantly affect premenopausal women with nonspecific gynecological symptoms, complicating early diagnosis.
• Preoperative imaging and tumor markers often misclassify these metastatic tumors as primary ovarian neoplasms.
• Histopathological examination with immunohistochemistry is essential for confirming diagnosis and identifying gastrointestinal origin.
• Cytoreductive surgery combined with systemic chemotherapy may improve survival in selected patients.
• Palliative chemotherapy and supportive care remain important for patients with widespread metastases where curative surgery is not feasible.
• Overall survival remains poor, emphasizing the need for early detection and multidisciplinary management.

Clinical Implications

Clinicians should maintain a high index of suspicion for Krukenberg tumors in women presenting with ovarian masses and nonspecific symptoms, especially when tumor markers and imaging are inconclusive. Multidisciplinary collaboration involving gynecologists, gastroenterologists, and oncologists is critical for accurate diagnosis and optimal treatment planning. Early surgical intervention combined with systemic chemotherapy may offer the best chance for prolonged survival.

Conclusion

Krukenberg tumors pose significant diagnostic and therapeutic challenges due to their metastatic nature and nonspecific presentation. This study underscores the importance of comprehensive histopathological evaluation and multidisciplinary management to improve patient outcomes.
