Malignant mixed ovarian germ cell tumor composed of immature teratoma, yolk sac tumor and embryonal carcinoma harboring an EGFR mutation: a case report.

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
Malignant mixed ovarian germ cell tumors are very rare, accounting for ~5.3% of all malignant ovarian germ cell tumors (MOGCTs), with a very high degree of malignancy. The treatment of patients with persistent, refractory, or platinum-resistant MOGCT is not well defined. The objective of this case report was to analyze the importance of chemotherapy, salvage surgery and target therapy in the treatment of a patient with refractory OGCT after first-line chemotherapy failure. We reported a 34 year-old woman suffered from advanced refractory MOGCT after first-line chemotherapy, cytoreductive surgery, and a series of chemotherapy. The genetic test shows she is a carrier of EGFR: p.L858R mutation. Based on genetic testing result, she received icotinib which targeted for EGFR mutation, but the tumor progressed. After a secondary cytoreductive surgery, she exhibited a partial response and continued to receive chemotherapy. This suggests that salvage surgery may be considered for patients with persistent or refractory MOGCTs when no effective systemic treatment option is available. Targeted therapies based on gene sequencing may provide a new option; however, its efficacy and related resistance mechanisms still need to be verified by further study.
