Pattern of failure and optimal treatment strategy for primary gastric diffuse large B-cell lymphoma treated with R-CHOP chemotherapy.
Article in PloS one, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeThe optimal treatment for primary gastric diffuse large B-cell lymphoma (PG-DLBCL) is still unknown. We evaluated unfavorable prognostic factors and pattern of failure in PG-DLBCL to determine the optimal treatment strategy.
methodsBetween April 2001 and November 2018, 120 patients with complete remission following rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) chemotherapy were retrospectively reviewed. According to the Lugano staging system, 80 patients (66.7%) had localized disease and 40 patients (33.3%) had advanced disease. A total of 93 (77.5%) patients had single gastric lesion and 27 (22.5%) patients had multiple gastric lesions. Ninety patients (75%) were treated with R-CHOP chemotherapy alone and 30 patients (25%) received R-CHOP chemotherapy with additional local treatment for gastric lesions.
resultsThe 5-year locoregional failure-free survival (LRFS), progression-free survival (PFS), and overall survival (OS) rates in patients treated with R-CHOP chemotherapy with local treatment were 100%, 100%, and 100%, respectively, whereas the LRFS, PFS, and OS rates in patients treated with R-CHOP chemotherapy alone were 86.3%, 78.2%, and 87.4%, respectively (p = 0.031, p = 0.095, and p = 0.025, respectively). During the follow-up period, 17 patients (14.2%) had disease recurrence. Only 3 of the 17 patients had relapse in a completely new site without relapse in the initial involved site. All, except 2, cases of local recurrence included gastric failure. In the multivariate analysis, performance status and number of gastric lesions were independent prognostic factors for treatment outcome.
conclusionsPatients with complete remission following R-CHOP chemotherapy showed a good prognosis. The main pattern of failure in patients with PG-DLBCL was local recurrence, especially in the stomach. Patients who received local treatment for gastric lesions showed improved gastric control. Therefore, in patients with unfavorable prognostic factors, we recommend R-CHOP chemotherapy with additional local treatment for gastric lesions.
