A population-based study on the prognostic impact of primary tumor sidedness in patients with peritoneal metastases from colon cancer.

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
Primary tumor location is an established prognostic factor in patients with (metastatic) colon cancer. Colon tumors can be divided into left-sided and right-sided tumors. The aim of this study was to determine the impact of primary tumor location on treatment and overall survival (OS) in patients with peritoneal metastases (PM) from colon cancer. This study is a retrospective, population-based cohort study. Records of patients diagnosed with colon cancer and synchronous PM, from 1995 through 2016, were retrieved from the Netherlands Cancer Registry (NCR). Data on diagnosis, staging, and treatment were extracted from the medical records by specifically trained NCR personnel. Information on survival status was updated annually using a computerized link with the national civil registry. In total, 7930 patients were included in this study; 4555 (57.4%) had a right-sided and 3375 (42.6%) had a left-sided primary tumor. In multivariable analysis right-sided primary tumor was associated with worse OS (HR: 1.11, 95% CI 1.03-1.19, P = .007). Of all patients diagnosed with PM, 564 (7.1%) underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). Patients with left-sided primary tumors were more often candidates for CRS-HIPEC (6.5% vs. 8.0%, P = .008). OS of patients with right- and left-sided tumors who underwent CRS-HIPEC did not significantly differ. In conclusion, primary right-sided colon cancer was an independent prognostic factor for decreased OS in patients diagnosed with synchronous PM. In patients treated with CRS-HIPEC location of the primary tumor did not influence survival.
