Association of RAS/BRAF Status and Prognosis of Metastatic Colorectal Cancer: Analysis of 1002 Consecutive Cases.
Article in Annals of surgical oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers.
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.
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
backgroundThis study aimed to analyze the association of RAS/BRAF status and the prognosis of patients with metastatic colorectal cancer (mCRC) based on multi-disciplinary team (MDT) treatment mode.
methodsThe study retrospectively analyzed 1002 consecutive mCRC patients with different tumor RAS/BRAF status at Zhongshan Hospital Fudan University from April 2012 to December 2018. The association of RAS/BRAF status with clinicopathologic features and prognosis was analyzed.
resultsThe mutation rate was 42.3% (424/1002) for RAS and 5.0% (50/1002) for BRAF. The RAS and BRAF mutations were mutually exclusive of each other. An association of RAS/BRAF status with sex (P < 0.001), age (P = 0.021), primary tumor location (P < 0.001), pathologic type (P < 0.001), differentiation (P < 0.001), metastatic organ (P < 0.001), carcinoembryonic antigen (CEA) (P < 0.001), and cancer antigen (CA)19-9 (P < 0.001) was observed. Overall survival (OS) was better for the RAS/BRAF wild-type patients than for the RAS-mutant patients, whereas the BRAF-mutant patients had the worst OS (51.0 vs 34.9 vs 18.9 months; P < 0.001). Regardless of RAS/BRAF status, metastases resection significantly improved OS (64.0 vs. 21.3 months; P < 0.001). Among the initially unresectable patients, the RAS/BRAF wild-type patients had a better conversional resection rate (32.9% vs 19.1% vs 0; P < 0.001) and a better OS (33.8 vs 23.3 vs 13.2 months; P = 0.005) than the RAS- and BRAF-mutant patients. Similarly, among the initially resectable patients, the RAS/BRAF wild-type patients had a better OS than the RAS- or BRAF- mutant patients (not assessable vs 51.7 vs 35.4 months; P = 0.005).
conclusionsThis large-sample study showed that regardless of metastases resection or no resection, RAS and BRAF mutations were associated with a poor prognosis. Resection of metastases could bring survival benefits for patients regardless of RAS/BRAF status.
