Vaginal germ cell tumors: results from the international retrospective VAGIPED study.
Article in British journal of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundVaginal malignant germ cell tumors (MGCTs), predominantly yolk sac tumors, are extremely rare, with no established consensus on optimal management. This study evaluated whether post-chemotherapy surgery is necessary for vaginal MGCTs.
methodsA retrospective analysis was conducted on patients diagnosed with vaginal MGCTs from 1996 to 2023. Progression-free survival (PFS), overall survival (OS), the impact of surgical intervention, and the presence of post-chemotherapy residual mass (RM) were assessed.
resultsSeventy-five patients (median age:11 months) were included. Six underwent initial tumor resection, and all received platinum-based chemotherapy. RM was detected post-chemotherapy in 57% of evaluable cases (40/70), with vaginoscopy outperforming standard imaging in detection (p < 0.001). The 5-year PFS and OS rates were 83% (95%CI: 71-90) and 94% (95%CI: 84-98), respectively. Neither RM (p = 0.64) nor delayed surgical intervention (5-year PFS: 77% (95%CI: 54-90) without surgery versus 85% (95%CI: 70-92) with surgery; log-rank test p = 0.72) significantly impacted PFS. DISCUSSION: Neoadjuvant platinum-based chemotherapy yields excellent survival outcomes in vaginal MGCTs. Vaginoscopy appears more sensitive than standard imaging for RM detection and is recommended for post-chemotherapy evaluation. In the absence of RM on vaginoscopy and with negative tumor markers, systematic post-chemotherapy surgery may be unnecessary. A global consensual framework for managing is proposed.
