Retrospective observational study of right hemicolectomy with hyperthermic intraperitoneal chemotherapy for appendiceal mucinous neoplasms at a single center over seven years.
Observational study in World journal of surgical 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
objectiveRetrospective analysis of the safety and efficacy of radical right hemicolectomy combined with hyperthermic intraperitoneal chemotherapy in the treatment of appendiceal mucinous tumors.
methodData were extracted from inpatient and outpatient medical records. Using R software (version 4.3.2), we collected all cases of appendiceal mucinous tumors treated with HIPEC at Jingzhou Hospital Affiliated to Yangtze University from February 2015 to February 2022 for statistical analysis and visualization. Survival analysis was performed using the 'survival' package, survival curves were plotted with 'survminer', and boxplots and percentage bar charts were generated using 'ggplot2'.
resultThis study included 61 patients with appendiceal mucinous tumors, of whom 31 received postoperative hyperthermic intraperitoneal chemotherapy (HIPEC) and 30 did not. At 2 years, recurrence occurred in 12.9% of the HIPEC group versus 46.7% of the control group (P = 0.004). The hazard ratio (HR) for recurrence-free survival (RFS) was 0.21 (95% CI: 0.07-0.63; P = 0.002). Overall survival (OS) at 2 years was 93.5% with HIPEC and 80.0% without, a difference that did not reach statistical significance (P = 0.147). Postoperative complication rates and baseline characteristics were comparable between groups.
conclusionOur findings demonstrate that radical right hemicolectomy combined with HIPEC significantly reduces postoperative recurrence rates in AMN patients while showing a non-significant trend toward improved overall survival.
