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

backgroundOvarian metastases are common in patients with colorectal cancer (CRC) with peritoneal metastases. For patients with bilateral macroscopically normal ovaries, prophylactic bilateral salpingo-oophorectomy (BSO) remains controversial. This study assessed the survival benefit of prophylactic BSO during cytoreductive surgery (CRS).

methodsThis retrospective cohort study included patients with CRC with peritoneal metastases who underwent CRS at two medical centres in southern China between 2017 and 2022. Patients achieving complete CRS with bilateral macroscopically normal ovaries were included in the subsequent analysis and divided into BSO and non-BSO groups. The primary outcomes of interest were the rates of synchronous and metachronous ovarian metastases. Clinical and surgical variables, including peritoneal carcinoma index (PCI) scores, were analysed for their correlation with these outcomes. Disease-free survival and overall survival were analysed using the Kaplan-Meier method, and prognostic variables were analysed using multivariate logistic regression.

resultsOf 237 consecutive patients who underwent CRS, 94 had macroscopically normal ovaries. Of these, 69 (29.1%) underwent complete CRS and were divided into two groups: 26 who underwent prophylactic BSO and 43 with organ preservation. In the BSO group, 7 patients (26.9%) had occult synchronous ovarian metastases. In the non-BSO group, 13 patients (30.2%) developed metachronous ovarian metastases, with 10 of these patients undergoing secondary surgery for ovarian metastases. Both synchronous and metachronous ovarian metastases were significantly associated with a higher PCI (P = 0.048). Premenopausal status was independently associated with metachronous ovarian metastases (hazard ratio 6.281; 95% confidence interval 1.364 to 28.922; P = 0.018). No significant differences were observed between the BSO and non-BSO groups in 2-year disease-free survival (P = 0.866) or overall survival (P = 0.557).

conclusionFor patients with CRC with peritoneal metastasis and bilateral macroscopically normal ovaries, prophylactic BSO does not improve mid-term survival.
