Late recurrence of primary cerebellar germinoma at unusual site after complete response to radiotherapy.
Article in Surgical neurology international, 2021. 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
backgroundThe primary cerebellar germinoma is exceptional and difficult to diagnose preoperatively. Its recurrence at the middle cranial fossa after complete response to radiotherapy is unique and associated with a poor prognosis. This article aims to report the successful management of the late recurrence of primary cerebellar germinoma at an unusual site after 4 years of complete response to radiotherapy. CASE DESCRIPTION: A 22-year-old male was admitted to our hospital with complaints of severe headache and loss of balance. Brain magnetic resonance imaging (MRI) showed a triventricular hydrocephalus due to a 45x50mm cerebellar mass. Our preliminary diagnosis was medulloblastoma. First, we placed a ventriculoperitoneal shunt with the medium-pressure valve, and then we used midline suboccipital craniotomy to remove the tumor completely. The histopathology was germinoma. The patient received 24 Gy craniospinal irradiation (CSI) with a 16 Gy boost to the primary site and had an MRI follow-up every six months. After a 4-year follow-up, he complained of recurrent severe headaches. The brain MRI illustrated a 62 × 61 mm temporal mass. We extirpated this tumor, and histopathology again revealed germinoma. After that, the patient received induction radiotherapy. The 1-year postoperative MRI showed no tumor remnant. At the time of writing, the patient had no headache and no neurological deficits.
conclusionRegular follow-ups with routine neuroaxis MRI should be recommended to detect recurrence early for all patients with intracranial germinomas. Surgical resection, if possible, and subsequent CSI are the most effective salvage treatment for recurrent germinoma.
