Clinicopathological Analysis of 17 Surgically Resected Pulmonary Pleomorphic Carcinoma Cases.

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
objectivesTo determine the outcomes and prognostic factors associated with pulmonary resection of pulmonary pleomorphic carcinoma (PPC).
methodsDuring 2008-2017, 17 patients underwent pulmonary resection for primary PPC at the Saitama Cancer Center, Japan. We investigated clinicopathological characteristics and outcomes of these cases. Overall survival (OS) and disease-free survival (DFS) rates were determined using Kaplan-Meier method and compared using log-rank test. Univariate analysis was performed to identify prognostic factors.
resultsThe 5-year OS and DFS rates were 27.2% and 51.0%, respectively. The median follow-up period was 30.8±24.9 (3.6-92.8) months after pulmonary resections. Patients with disease-free interval (DFI) <1 year of resection had poorer prognosis than those without (p = 0.001). Patients with N2 status and adenocarcinoma components had significantly poorer disease-free prognosis than their counterparts (p = 0.021 and p = 0.019, respectively). Univariate analysis revealed that DFI <1 year was an unfavorable prognostic factor for OS (p = 0.005); N2 pathological status and presence of adenocarcinoma components were unfavorable prognostic factors for DFS (p = 0.038 and p = 0.036, respectively).
conclusionPPC patients with an adenocarcinoma component and N2 pathological status may have an earlier relapse and poorer prognosis than their counterparts. Further assessment of cases may help clarify the predictors of PPC.
