Treatment outcomes of the external auditory canal and temporal bone malignancy with dura invasion.

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
Objectives: This study aimed to evaluate the characteristics and surgical outcomes of patients with external auditory canal (EAC) and temporal bone (TB) malignancy with dura invasion. Methods: The medical records of patients with EAC and TB malignancy with dura invasion were retrospectively reviewed. Survival outcomes (overall survival [OS], disease-specific survival [DSS], recurrence-free survival [RFS], and distant metastasis-free survival [DMFS]) were analyzed using the Kaplan-Meier method. Results: A total of eight patients were included in this study. The median age at diagnosis was 49.5 years (range 12-74 years). The median follow-up periods were 46.5 months. Histologically, four out of eight patients were diagnosed with squamous cell carcinoma (SCC; 50%). The 2-year OS and DSS rates of all patients were 62.5%, and those of EAC SCC patients were 50% and 66.7%, respectively; while the 2-year RFS and DMFS rates of all patients were 37.5%. There was one local recurrence at the resection site (12.5%), two regional neck nodal recurrences (25%), and two distant metastases (25%). Dura resection and duroplasty areas were not involved in the local recurrence case. Conclusion: In EAC and TB cancer with dura invasion, radical surgery with dura resection may show similar survival outcomes to previous studies without recurrence at the dura resection site.Level of evidence: IV.
