1 · What the graph read from it

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.

2 · The registry

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 aim of this study was to determine the practice patterns and outcomes of intracranial germ cell tumors (IGCT) in adolescents and young adults according to different therapeutic approaches. METHODS AND MATERIALS: One-hundred twelve patients with IGCT aged 15 to 39 years were managed at either XX or the XY center from 1975 to 2015. The charts were retrospectively reviewed and data collected.

resultsMedian duration of follow-up was 8.3 years. Ninety-four patients had germinomas, and 18 had nongerminomatous germ cell tumors (NGGCT). The primary disease sites were pineal gland (37 of 94 germinoma, 14 of 18 NGGCT) and suprasellar region (23 of 94 germinoma, 2 of 18 NGGCT). Eleven patients with germinoma (12%) and 2 patients with NGGCT (11%) had radiographic spinal metastases or positive lumbar cerebrospinal fluid cytology. Event-free survival (EFS) was 84% and overall survival (OS) was 90% at 10 years for germinoma; EFS was 71% and OS was 86% at 10 years for NGGCT. For patients with germinoma, 10-year EFS was 100% after craniospinal radiation therapy (CSRT) with chemotherapy (N = 10); 100% after whole-ventricular radiation therapy (WVRT), whole-brain radiation therapy (WBRT), or focal radiation therapy (FRT) with chemotherapy (N = 22); 90% after CSRT alone (N = 46); and 41% after WVRT, WBRT, or FRT alone (N = 16) (P < .0005). Ten-year OS was 100%, 100%, 90%, and 72%, respectively (P = .032). For patients with NGGCT, 10-year EFS was 80% after CSRT, WBRT, or WVRT plus chemotherapy (N = 10) versus 58% after FRT plus chemotherapy (N = 8) (P = .31); 10-year OS was 90% versus 58%, respectively (P = .16).

conclusionsWe report excellent overall outcomes according to treatment approach in the largest study of IGCT in adolescents and young adults to our knowledge. EFS and OS were inferior after non-CSRT without chemotherapy in germinoma.
