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

backgroundPulmonary sarcomatoid carcinoma is a rare tumor that is resistant to cytotoxic agents. This observational study aimed to evaluate the detection rate of driver gene alteration and the efficacy of targeted therapy for pulmonary sarcomatoid carcinoma.

methodsWe established a database of patients with pulmonary sarcomatoid carcinoma and their clinical information, including EGFR mutation, ALK fusion gene, ROS1 fusion gene, BRAF mutation, and MET exon 14 skipping mutation. The present study retrieved and analyzed the data of patients with pulmonary sarcomatoid carcinoma in whom driver gene alterations were evaluated, and the survival duration after the initiation of treatment with targeted therapy was examined.

resultsA total of 44 patients were included in the present study. The EGFR mutation, ALK fusion gene, and MET exon 14 skipping mutation were detected in 2/43 patients (4.7%), 2/34 patients (5.9%), and 2/16 patients (12.5%), respectively. The ROS1 fusion gene (0/18 patients) and BRAF mutation (0/15 patients) were not detected. Female patients (P = 0.063, Fisher's exact test) and patients without smoking history (P = 0.025, Fisher's exact test) were the dominant groups in which any driver mutation was detected. Five patients with driver gene alterations were treated with targeted therapy. Progression-free survival (PFS) was 1.3 months and 1.6 months in 2 of the patients treated with gefitinib. Two patients with the ALK fusion gene showed 2.1 and 14.0 months of PFS from the initiation of treatment with crizotinib, and a patient with the MET exon 14 skipping mutation showed 9.7 months of PFS from the initiation of treatment with tepotinib.

conclusionThe EGFR mutation, ALK fusion gene, and MET exon 14 skipping mutation were detected in patients with pulmonary sarcomatoid carcinoma in clinical practice, and some patients achieved long survival times after receiving targeted therapy. Further investigation is necessary to evaluate the efficacy of targeted therapy for pulmonary sarcomatoid carcinoma.
