Treatment and prognosis of colorectal cancer with synchronous peritoneal metastases: 11-year single institute experience.
Article in eGastroenterology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Treatment of colorectal cancer (CRC) with synchronous peritoneal metastases (SPM) is controversial, and its prognosis remains poor. Here, we analysed the association between treatment strategies and the outcomes of patients with colorectal SPM and devised a nomogram to improve their prognosis prediction. Methods: We retrospectively analysed patients with colorectal SPM treated at The Sixth Affiliated Hospital, Sun Yat-sen University from June 2007 to June 2018. The Kaplan-Meier method with log-rank tests was used to compare the overall survival (OS) among patients undergoing different therapeutic regimens. Cox proportional hazards regression analysis was used to identify the prognostic factors. After variable selection, a nomogram was developed to predict the OS of patients with colorectal SPM. Results: A total of 371 patients with colorectal SPM were eligible for this study. The median OS of all patients was 15.0 months (95% CI, 13.1 to 16.9), with a 3-year and 5-year OS rate of 23.7% and 16.9%, respectively. Patients who underwent complete cytoreductive surgery (CC0-1) had a better median OS of 49 months (p<0.001). Cox multivariate analysis showed that age >65 years; cancer antigen 125 level >35 U/mL; peritoneal carcinomatosis index >16 scores; and undergoing cytoreductive surgery, chemotherapy and hyperthermic intraperitoneal chemotherapy were independent prognostic factors for OS. The c-index of the prognostic nomogram was 0.747 (95% CI, 0.474 to 1.020). Conclusions: Our study suggests that patients with colorectal SPM who receive comprehensive treatment might achieve better prognoses. The prognostic nomogram demonstrated good predictive performance for patients with colorectal SPM.
