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

backgroundPulmonary metastasectomy is considered a standard procedure in the treatment of metastatic colorectal cancer (CRC). Different prognostic factors including multiple metastatic nodules, the presence of extra-pulmonary metastases and BRAF mutation status have been associated with poor survival. The aim of this study was to evaluate which factors influenced survival in CRC patients undergoing pulmonary metastasectomy by studying primary tumors and pulmonary metastases.

methodsAll patients treated for primary CRC who presented pulmonary metastases in a 10-year period were considered (group A). A control group treated for primary CRC who did not develop any pulmonary or extra-pulmonary metastases was taken for comparison (group B). Different prognostic factors including gender, age, tumor location, histological type, inflammatory infiltrate, BRAF, CDX2 and extra-pulmonary metastases were analyzed. Overall survival (OS) and patients' survival after pulmonary metastasectomy were also considered.

resultsFifty-four patients were evaluated in group A and twenty-three in group B. In group A, BRAF immunohistochemistry did not significantly differ between primary tumors and pulmonary metastases; no difference of BRAF expression was found between group A and B. Even the expression of CDX2 was not significantly different in primary tumors and metastases. Similarly, in group B CDX2 did not significantly differ from primary CRC of group A. The most significant prognostic factor was the presence of extra-pulmonary metastases. Patients with extra-pulmonary metastases experienced a significant shorter survival compared to patients with pulmonary metastases alone (P=0.001 with log-rank test

conclusionsThe main prognostic factor associated with poor survival after lung resection of CRC metastases is a history of extra-pulmonary metastases. BRAF and CDX2 did not have a significant role in this small series of patients.
