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

backgroundThe clinical benefits of conversion chemotherapy followed by liver resection for initially unresectable colorectal liver metastases are still controversial. The criteria for unresectability vary from one team to another. To clarify this issue, we retrospectively assessed the survival and characteristics of metastatic colorectal cancer (mCRC) patients with liver-limited disease (LLD) who underwent conversion therapy.

methodOur criteria for resectability depended on the size of the remnant liver volume (>30 %) and expected function after removal of all metastases. Between December 2007 and September 2011, a total of 115 patients were diagnosed as having mCRC with LLD and received chemotherapy. Among them, 47 had tumors that were initially diagnosed as resectable. They underwent hepatic resection after chemotherapy (resected group). Of the 67 tumors were initially diagnosed as unresectable, 12 became resectable after chemotherapy (conversion group), leaving 55 tumors that remained unresectable after chemotherapy (unresected group).

resultsThe median follow-up was 25.2 months. Hepatic resection was more invasive in the conversion group than in the resected group. Median disease-free survival was significantly higher in the resected group than in the conversion group (p = 0.013). Overall survival (OS) was also higher in the resected group, but the difference was not significant (p = 0.36). However, OS was significantly higher in the conversion group than in the unresected group (p = 0.034). Multivariate analysis of the resected and conversion groups showed that OS was significantly negatively influenced by abnormal carcinoembryonic antigen levels at surgery (p = 0.037) and a hospital stay >30 days (p = 0.009).

conclusionsOur results showed that conversion chemotherapy could contribute to longer OS in mCRC patients with LLD.
