Survival prognostic analysis of laparoscopic D2 radical resection for locally advanced gastric cancer: A multicenter cohort study.

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
backgroundWith the development of minimally invasive surgical techniques, the use of laparoscopic D2 radical surgery for the treatment of locally advanced gastric cancer (GC) has gradually increased. However, the effect of this procedure on survival and prognosis remains controversial. This study evaluated the survival and prognosis of patients receiving laparoscopic D2 radical resection for the treatment of locally advanced GC to provide more reliable clinical evidence, guide clinical decision-making, optimize treatment strategies, and improve the survival rate and quality of life of patients.
aimTo investigate the survival prognosis and influencing factors of laparoscopic D2 radical resection for locally advanced GC patients.
methodsA retrospective cohort study was performed. Clinicopathological data from 652 patients with locally advanced GC in our hospitals from December 2013 to December 2023 were collected. There were 442 males and 210 females. The mean age was 57 ± 12 years. All patients underwent a laparoscopic D2 radical operation for distal GC. The patients were followed up in the outpatient department and by telephone to determine their tumor recurrence, metastasis, and survival. The follow-up period ended in December 2023. Normally distributed data are expressed as the mean ± SD, and normally distributed data are expressed as M (Q1, Q3) or M (range). Statistical data are expressed as absolute numbers or percentages; the
resultsThe median overall survival (OS) time for the 652 patients was 81 months, with a 10-year OS rate of 46.1%. Patients with TNM stages II and III had 10-year OS rates of 59.6% and 37.5%, respectively, which were significantly different (
conclusionA maximum tumor diameter exceeding 4 cm, low tumor differentiation, and pathological TNM stage III were identified as independent risk factors for the 10-year OS rate in patients with locally advanced GC following laparoscopic D2 radical resection for distal GC. Conversely, postoperative chemotherapy was found to be an independent protective factor for the 10-year OS rate in these patients.
