Factors Associated with Survival in Pediatric Extracranial Germ Cell Tumors: A Study Focusing on Postoperative Alpha-Fetoprotein.
Article in Asian Pacific journal of cancer prevention : APJCP, 2025. 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
backgroundAlpha-fetoprotein (AFP) is commonly used in the management of pediatric extracranial germ cell tumors (eGCT), but its prognostic role remains unclear. We investigated survival outcomes and the impact of serial AFP changes after surgery.
methodWe analyzed data from 129 pediatric eGCT patients (age 0-15) who underwent surgery at our institution. We evaluated overall survival (OS) and recurrence-free survival (RFS). in non-benign eGCTs, serial AFP measurements were performed postoperatively.
resultsOS and RFS were 87.4% and 82.6%, respectively. Poorer survival was associated with male sex, non-sacrococcygeal extragonadal site, yolk sac tumor/choriocarcinoma histology, initial AFP > 50,000 ng/mL, and operative complications. Postoperative log-AFP values showed significant differences between long-term survivors and non-survivors from one month onwards. AFP normalization (<100 ng/mL) at one month was associated with improved 5-year OS (93.4% vs. 69.4%, p=0.031).
conclusionSerial AFP measurement from one month post-surgery has prognostic value in pediatric eGCT. Patients who fail to normalize AFP should be closely monitored for recurrence.
