Unexpected metachronous multiple primary cancers: pilonidal sinus‑related squamous cell carcinoma and incidentally detected gastric gastrointestinal stromal tumour.

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
This case report presents a 62‑year‑old male with chronic pilonidal disease that underwent malignant transformation into squamous cell carcinoma (SCC), followed 18 months later by incidental detection of a gastric gastrointestinal stromal tumour (GIST) during routine oncologic surveillance. Initial contrast‑enhanced CT revealed the gluteal SCC, which was surgically excised and treated with adjuvant radiotherapy. Subsequent CT scan indicates a well‑circumscribed mass in the submucosa of the stomach. MRI and endoscopic biopsy confirmed a submucosal gastric GIST, which was completely resected. No recurrence of either malignancy has been observed on follow‑up. This case underscores the pivotal role of multimodality imaging in diagnosis, staging, and longitudinal care.
