Pneumonectomy for an endobronchial carcinosarcoma with long-term survival: a case report.
Article in AME case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Endobronchial carcinosarcoma is a rare and highly malignant tumor composed of both carcinomatous and sarcomatous elements. It typically affects middle-aged and elderly men, particularly those with a history of smoking. The prognosis is generally poor due to its high potential for early metastasis and local recurrence. This case report is unique due to the presentation of endobronchial carcinosarcoma, exhibiting a gloved finger sign, coarse calcifications, and high Case Description: A 48-year-old man with a 30-year history of chronic productive cough, a 1-month history of shortness of breath, and a significant smoking history presented to The First Affiliated Hospital of Guangzhou Medical University. Initial examinations revealed elevated neuron-specific enolase (NSE) and reduced partial pressure of oxygen. Computed tomography identified a branching tubular mass in the left upper lobe with a gloved finger sign and coarse calcifications. Conclusions: This case illustrates that the gloved finger sign may reflect early bronchial obstruction and prompt clinical evaluation. Despite preoperative imaging suggestive of disease progression, the patient underwent R0 pneumonectomy and has remained recurrence-free for 7 years without receiving neoadjuvant or adjuvant therapy. Exceptional long-term survival after R0 resection alone may be possible in some certain patients.
