FOLFOXIRI-Bevacizumab or FOLFOX-Panitumumab in Patients with Left-Sided RAS/BRAF Wild-Type Metastatic Colorectal Cancer: A Propensity Score-Based Analysis.

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
backgroundDoublets plus anti-epidermal growth factor receptors (EGFRs) are the preferred upfront option for patients with left-sided RAS/BRAF wild-type metastatic colorectal cancer (mCRC). Initial therapy with FOLFOXIRI-bevacizumab is superior to doublets plus bevacizumab independently from primary tumor sidedness and RAS/BRAF status. No randomized comparison between FOLFOXIRI-bevacizumab versus doublets plus anti-EGFRs is available in left-sided RAS/BRAF wild-type mCRC. MATERIALS AND
methodsWe selected patients with left-sided RAS and BRAF wild-type mCRC treated with first-line FOLFOX-panitumumab or FOLFOXIRI-bevacizumab in five randomized trials: Valentino, TRIBE, TRIBE2, STEAM, and CHARTA. A propensity score-based analysis was performed to compare FOLFOXIRI-bevacizumab with FOLFOX-panitumumab.
resultsA total of 185 patients received FOLFOX-panitumumab and 132 received FOLFOXIRI-bevacizumab. Median progression-free survival (PFS) and median overall survival (OS) were 13.3 and 33.1 months in the FOLFOXIRI-bevacizumab group compared with 11.4 and 30.3 months in the FOLFOX-panitumumab group (propensity score-adjusted hazard ratio (HR) for PFS, 0.82; 95% confidence interval (CI), 0.64-1.04; p = .11; propensity score-adjusted HR for OS, 0.80; 95% CI, 0.59-1.08; p = .14). No significant differences in overall response rate and disease control rate were observed. A statistically nonsignificant difference in favor of FOLFOXIRI-bevacizumab was observed for OS after secondary resection of metastases. Chemotherapy-related adverse events were more frequent in the FOLFOXIRI-bevacizumab group, with specific regard to grade 3 and 4 neutropenia (48% vs. 26%, adjusted p = .001).
conclusionAlthough randomized comparison is lacking, both FOLFOXIRI-bevacizumab and FOLFOX-panitumumab are valuable treatment options in left-sided RAS/BRAF wild-type mCRC. IMPLICATIONS FOR PRACTICE: A propensity score-based analysis of five trials was performed to compare FOLFOX-panitumumab versus FOLFOXIRI-bevacizumab in left-sided RAS/BRAF wild-type metastatic colorectal cancer (mCRC). No significant differences were observed, but FOLFOXIRI-bevacizumab achieved numerically superior survival outcomes versus FOLFOX-panitumumab. Chemotherapy-related adverse events were more frequent in the FOLFOXIRI-bevacizumab group. These observations suggest that although doublet chemotherapy plus anti-EGFRs remains the preferred treatment in patients with left-sided RAS/BRAF wild-type mCRC, FOLFOXIRI-bevacizumab is a valuable option able to provide similar, if not better, outcomes at the price of a moderate increase in toxicity and may be adopted based on patients' preference and potential impact on quality of life.
