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

backgroundMetastasis to the ovary from nongynecologic organs accounts for 9% of all ovarian malignancies. Although the most common nongynecologic primary site of ovarian metastasis is the gastrointestinal tract, metastasis from other sites to the ovary is not uncommon. Differential diagnosis of primary and metastatic ovarian tumors is important; otherwise, appropriate treatment cannot be determined. Furthermore, an optimal treatment strategy for ovarian metastasis from nongynecologic primary sites still needs to be explored.

methodsOne hundred seventy-seven patients with ovarian metastasis from nongynecologic primary sites admitted to Peking Union Medical College Hospital between May 2005 and May 2018 were retrospectively evaluated.

resultsThe mean age was 48 years (range, 18-83). Approximately 60% of patients were premenopausal women. The two most common nongynecologic primary sites of ovarian metastasis were the colorectum (68 cases) and stomach (61 cases). In addition to the most common symptoms of abdominal distension (39.0%), abdominal pain (37.9%), and ascites (27.7%), 18.1% of patients presented with abnormal uterine bleeding. Half of the patients who tested serum CA-125 preoperatively had elevated CA-125 levels within the range of 35 U/ml to 200 U/ml. More than 70% of synchronous ovarian metastases were preoperatively misdiagnosed as primary ovarian cancer. Of all included cases, 56.5% achieved optimal cytoreductive surgery (the diameter of the largest residual lesion < 2 cm). The overall 5-year survival rate and median survival time were 10% and 20 months, respectively. The primary site, optimal cytoreductive surgery, tumor differentiation, and postoperative adjuvant treatment were identified as prognostic indicators.

conclusionsThe colorectum and stomach are the most common nongynecologic primary sites of ovarian metastasis. Synchronous ovarian metastasis is easily misdiagnosed as primary ovarian cancer. Optimal cytoreductive surgery and postoperative adjuvant treatment can be performed to confer survival benefit in selected patients.
