Treatment outcomes for response-based radiotherapy in children and adolescents with central nervous system germinoma: a prospective study.
Article in Journal of neuro-oncology, 2023. 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
purposeThe optimal dose and range of radiotherapy for central nervous system (CNS) germinoma have not yet been established. This study aimed to investigate the effects of individualized radiotherapy on the prognosis of patients with germinoma.
methodsBased on imaging examination, tumor markers, and pathologic results, patients with germinoma received different radiotherapy strategies, including R1 (24 Gy whole ventricular irradiation + tumor-bed boost to 40 Gy), R2 (24-30 Gy craniospinal irradiation + tumor-bed boost to 54 Gy), R3 (24 Gy craniospinal irradiation + tumor-bed boost to 40 Gy), and R4 (30 Gy craniospinal irradiation + tumor-bed boost to 54 Gy with 45 Gy to spinal metastasis).
resultsA total of 77 patients were enrolled in this study between January 2015 and March 2021. The 3-year event-free survival (EFS) and overall survival (OS) of the whole cohort were 94.7% ± 2.6% and 96.0% ± 2.3%, respectively. The 3-year EFS for patients with localized and metastatic disease were 96.6% ± 2.4% and 89.2% ± 7.2%, respectively. The 3-year EFS of patients receiving R1, R2, R3, and R4 radiotherapy were 100%, 94.1% ± 5.7%, 100%, and 86.2% ± 9.1%, respectively.
conclusionGood prognosis was still achieved after reducing dose and extent of radiation for the patients who achieved complete response (CR) after induction chemotherapy or pathological CR after second-look surgery.
