Markedly elevated alpha-fetoprotein leading to the diagnosis of high-grade endometrial carcinoma during hepatocellular carcinoma surveillance.

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: Alpha-fetoprotein (AFP) is widely used for hepatocellular carcinoma surveillance in patients with chronic liver disease. AFP is rarely elevated in endometrial cancer but may be a useful marker of aggressive histologic variants. Case: A 70-year-old woman with autoimmune hepatitis-associated cirrhosis undergoing hepatocellular carcinoma (HCC) surveillance developed a rapid rise in AFP from 5 ng/mL to greater than 13,000 ng/mL. Liver imaging revealed no evidence of HCC. Positron-emission tomography (PET) demonstrated focal uptake in the uterus. Pelvic magnetic resonance imaging identified a deeply invasive endometrial mass. Hysteroscopic biopsy revealed high-grade endometrial carcinoma. The patient subsequently underwent total laparoscopic hysterectomy with bilateral salpingo-oophorectomy (TAH-BSO) with pathology demonstrating a stage IB high-grade endometrial carcinoma with extensive somatic-type glandular yolk sac / fetal-type differentiation and minor carcinosarcoma component (<5%). Serum AFP steadily and rapidly decreased after surgery. Conclusion: This case highlights the importance of considering extrahepatic sources of AFP elevation and demonstrates an unusual presentation of endometrial carcinoma detected during HCC surveillance.
