De-differentiated metastatic adenosquamous carcinoma arising from germ cell tumor in the brain and spine.

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
Intracranial germ cell tumors have an estimated incidence of 0.4-3.4% in the Western Hemisphere. Patients can present with a variety of differing clinical signs and symptoms including headache, nausea/vomiting, hydrocephalus, obtundation, pyramidal tract signs, ataxia, and hypothalamic/pituitary dysfunction. Rarely germ cell tumors can transform into alternative malignancy. In these cases, treatment options may be difficult. Metastasis to the brain is not uncommon in germ cell tumors and is frequently reported within the pineal region; however, they are less common intraventricularly, within the posterior fossa and have never been reported after malignant transformation. Herein, we present the first reported case of a metastatic adenosquamous carcinoma transformed from a yolk sac tumor with diffuse cerebral metastasis in atypical locations of the brain including intraventricular and posterior fossa. A 53-year-old right-handed Caucasian female was transferred from an outside hospital for a chief complaint of altered mental status with CT head showing right side intraventricular mass and cerebellar hemorrhage. MRI of the brain found multifocal contrast-enhancing lesions of the right lateral ventricle, right cerebellum, right frontal lobe, diffuse lumbar dural enhancement, and an intramedullary lesion at the cervico-medullary junction of the brainstem. The right lateral ventricular lesion and right cerebellar lesions were resected. Pathology findings support a diagnosis of adenosquamous carcinoma, and the morphologic and immunophenotypic features suggest development as a somatic malignancy in a germ cell neoplasm with features of a yolk sac tumor. Germ cell tumors are typically included within the differential of pineal region masses; however, other locations such as intraventricular and posterior fossa are rarely seen. Even rarer are cases with malignant transformation to an alternative lesion for which treatment options are exceptionally scarce. Neurosurgeons and oncologists alike should be aware of this rare possible lesion to add to a broad differential diagnosis.
