Endoscopic submucosal dissection in Helicobacter pylori-negative early gastric adenocarcinoma with diffuse large B-cell lymphoma: a two-case report and literature review.

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
We describe two rare cases of synchronous early gastric adenocarcinoma (EGA) and diffuse large B-cell lymphoma (DLBCL) involving the stomach and colon in Helicobacter pylori-negative patients. Case 1: A 61-year-old male presenting with abdominal pain was diagnosed with synchronous EGA and colonic DLBCL via endoscopy. Following 8 cycles of R-CDOP chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). The patient subsequently underwent endoscopic submucosal dissection (ESD) for EGA without gastrectomy. Case 2: A 67-year-old male with a history of gastric DLBCL (treated with 9 cycles of R-CDOP within 6 months) was diagnosed with EGA on surveillance gastroscopy and managed with ESD. Both patients achieved complete resection and remained disease-free at 16-month follow-up. These cases highlight the feasibility of ESD as a curative option for Helicobacter pylori-negative EGA coexisting with DLBCL.
