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

purposeThis study aimed to clarify the key factors for minimizing unsuitable surgical interventions for patients with radiologically occult metastatic pancreatic cancer (ROMPC), defined as a distant metastasis detected during surgery or within 6 months after resection.

methodsThis study involved 502 patients planned to undergo curative resection for pancreatic cancer between 2008 and 2015. Patients were divided into ROMPC and non-ROMPC groups and evaluated preoperative factors associated with ROMPC.

resultsOverall survival (OS) was significantly lower in the ROMPC group (n = 145) than the non-ROMPC group (n = 357, median survival time [MST] 10.8 vs. 35.3 months, P < 0.001). In the ROMPC group, OS tended to be worse for patients who had pancreatectomies (n = 84) than those who did not (n = 61, MST 10.1 vs. 13.2 months, P = 0.057), and the next chemotherapy started significantly later in patients who had pancreatectomies (P < 0.001). Moreover, OS was significantly lower for patients with (n = 82) than without (n = 63) liver metastases (MST 9.7 vs. 13.0 months, respectively, P = 0.020). The best indicator for patients at higher risk of ROMPC was a combination of carbohydrate antigen 19-9 concentration ≥ 300 U/ml and tumor size ≥ 30 mm.

conclusionsIn the ROMPC group, patients who underwent pancreatectomy had a poorer prognosis than patients not undergoing pancreatectomy. Given that the liver was the most frequent distant metastatic site for ROMPC and had the poorest prognosis, establishing a strategy featuring new imaging modalities to detect radiologically occult liver metastases is necessary.
