1 · What the graph read from it

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.

2 · The registry

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

objectiveThe aim of this nationwide study was to provide insight in the incidence, risk factors, treatment, and survival of patients with ovarian metastases from colorectal cancer (CRC).

methodsData from the Netherlands Cancer Registry were used. All newly diagnosed female CRC patients between 2008 and 2016 were included. Treatment was categorized as follows: cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (CRS-HIPEC); resection of the primary tumor; palliative treatment; and no treatment. Overall survival (OS) was investigated using Kaplan-Meier and multivariable Cox regression analyses.

resultsOf 53,883 female CRC patients, 11,343 (21.1%) had metastases at time of diagnosis. Among them, 471 (4.2%) had ovarian metastases. Within latter group, 27.2% received CRS-HIPEC; 38.4% underwent resection of the primary tumor; 25.3% received palliative treatment; and 9.1% received no treatment. Median OS of all patients with ovarian metastases was 17.5 months. In patients receiving CRS-HIPEC, OS was significantly longer than in patients undergoing resection only (median OS 34.1 vs. 17.5 months, adjusted HR 0.44 [0.33-0.66]). Five-year OS was 28.5% for patients having underwent CRS-HIPEC, 11.0% for patients having underwent resection of the primary tumor, 1.2% for patients having underwent palliative treatment, and 0.0% for patients without treatment.

conclusionsSynchronous ovarian metastases are diagnosed in 4.2% of female colorectal patients presenting with metastatic disease. Risk factors are young age, T4/N+ tumor and histology of signet ring cell carcinoma. Median OS of the entire cohort was 17.5 months, ranging from 3.1 months in patients without treatment to 34.1 months in patients undergoing CRS-HIPEC.
