Advanced gastric small cell carcinoma with immunotherapy-based treatment: A case report.
Article in World journal of gastrointestinal oncology, 2025. 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
backgroundThe clinical and pathological characteristics of primary gastric small cell carcinoma (GSCC) resemble those of small cell lung cancer, which is less sensitive to chemotherapy and has a poor prognosis. Currently, platinum-etoposide chemotherapy is a primary chemotherapy regimen for small cell carcinoma, but it is still imperfect. Programmed cell death ligand 1 (PD-L1) inhibitors are recommended for the treatment of small cell lung cancer. However, to determine whether PD-L1 inhibitors are optimal for metastatic GSCC requires more clinical data. CASE SUMMARY: A 67-year-old male experienced upper abdominal pain without any obvious cause for 1 week. Gastroscopy examination revealed a mass in the gastric body. Pathological examination of the biopsy specimen combined with immunohistochemistry showed a high-grade neuroendocrine carcinoma (small cell carcinoma). Genetic tests showed
conclusionGSCC is a highly malignant tumor with a poor prognosis. Whether immune-related drugs are optimal for metastatic GSCC requires further exploration.
