Bilateral ovarian metastases from gastric signet-ring cell carcinoma in an 18-year-old: a case report and narrative review.
Review in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background/objectives: Krukenberg tumors (KTs) are rare metastatic ovarian neoplasms, most frequently secondary to gastric adenocarcinomas, and typically occur in women aged 30-60 years. Their presentation in adolescents is exceedingly uncommon and often leads to diagnostic delays due to nonspecific symptoms and low clinical suspicion. Case presentation: We describe the case of an 18-year-old female presenting with progressive abdominal pain and bilateral adnexal masses. Imaging suggested advanced ovarian pathology, and surgical exploration with histopathological evaluation confirmed metastatic signet-ring cell carcinoma. Upper gastrointestinal endoscopy subsequently identified a poorly differentiated gastric adenocarcinoma, establishing the diagnosis of KT. Methods: To place this case in context, a narrative literature review was performed using PubMed, Google Scholar, and ScienceDirect. English-language case reports and case series describing KTs in patients aged ≤20 years were selected. Fifteen studies were analyzed regarding clinical presentation, histopathological features, diagnostic approach, and patient outcomes. Results: The majority of reported cases demonstrated bilateral ovarian involvement, vague abdominal symptoms, and gastric origin. Diagnostic delays were frequent, and prognosis remained poor despite multimodal treatment strategies. Conclusions: This case highlights the importance of considering metastatic gastrointestinal malignancies in the differential diagnosis of ovarian tumors in adolescents and emphasizes the value of early endoscopic assessment. By combining a rare adolescent case with a focused literature review, this work provides one of the few comprehensive syntheses of KTs in patients under 20 years, offering a unique contribution to improving clinical awareness and guiding future diagnostic strategies.
