Correlation between laparoscopic radical resection and tumor markers in peritoneal irrigation fluid.
Article in World journal of gastrointestinal surgery, 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
backgroundGastric cancer (GC) is one of the most common malignancies and types of cancer worldwide.
aimTo compare the differences in tumor markers of GC with GC dissection, we evaluated the efficacy of recent tumor removal.
methodsA prospective cohort study was conducted to analyze the clinical data of patients with GC. Patients were divided into two groups based on the surgical approach: The membrane dissection (MD) group, which underwent membrane-guided laparoscopic radical gastrectomy with D2 lymph node dissection plus complete mesocolic excision, and the D2 group, which underwent traditional laparoscopic radical gastrectomy with D2 lymph node dissection. Abdominal lavage fluid was collected pre- and postoperatively from patients in both groups. The expression of carcinoembryonic antigen (CEA) and cytokeratin-19 (CK-19) message RNAs in the abdominal lavage fluid was detected using reverse transcription polymerase chain reaction. The factors influencing the increase of the tumor markers were analyzed, and the short-term efficacy of the two surgery types was compared.
resultsIn total, 135 eligible patients were included in this study, with 69 and 66 cases in the MD and D2 groups, respectively. Fourteen patients with benign gastric lesions were selected to detect tumor marker expression. After excluding patients positive for preoperative cancer leakage, we found that 9.52% and 26.67% of patients in the MD and D2 groups developed postoperative CEA positivity, respectively. Multivariate analysis revealed that the degree of differentiation and surgical approach were independent risk factors for postoperative CEA positivity. The surgical approach was an independent risk factor affecting postoperative CK-19 positivity and postoperative CEA and CK-19 positivity. Surgical time, intraoperative blood loss, number of lymph nodes dissected, time to first postoperative flatus, and time to first liquid intake were all significantly different between the two surgical approaches. There were no significant differences in the incision length, duration of postoperative hospital stays, or postoperative complications.
conclusionMD is a better radical surgical treatment than traditional D2 surgery and is worthy of further clinical promotion and application.
