Real-world treatment patterns and outcomes among patients initiating sequential regorafenib and trifluridine/tipiracil ± bevacizumab in patients with metastatic colorectal cancer in a US community setting (SEQRT2).

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
Background: Regorafenib and trifluridine/tipiracil (FTD/TPI) ± bevacizumab are both indicated for patients diagnosed with metastatic colorectal cancer (mCRC) in the third line or later. However, in the absence of recommendations regarding preferred treatment order, our study aimed to improve the understanding of real-world optimal treatment sequences. Methods: This retrospective study assessed real-world outcomes and treatment patterns among mCRC patients who initiated sequential regorafenib and FTD/TPI ± bevacizumab between the first line and sixth line from September 2015 to November 2022 in The US Oncology Network. Patient and treatment characteristics were assessed descriptively overall and stratified by treatment order. The Kaplan-Meier methods were used for time-to-event endpoints, including real-world overall survival (rwOS), real-world progression-free survival (rwPFS), and real-world time to next treatment (rwTTNT) following sequence. Endpoints were also evaluated using Cox proportional hazards models. Results: This study examined 308 patients initiating sequential regorafenib and FTD/TPI, 156 patients initiating regorafenib first (R-T), and 152 patients initiating FTD/TPI first (T-R). Demographic and clinical characteristics were similar across cohorts. The population was predominantly male and had a mean age of 63 years and colon primary at diagnosis. The median rwOS was numerically longer among the R-T cohort compared to the T-R cohort (12.8 [11.2, 14.1] vs. 10.2 [8.8, 11.9] months). The median rwPFS was similar (3.4 [3.0, 3.6] vs. 3.4 [3.0, 3.7 months) for both the R-T and T-R cohorts. The median rwTTNT following sequence was numerically longer among the R-T cohort compared to the T-R cohort (9.3 [8.4, 10.3] vs. 8.6 [7.8, 9.4] months). Index treatment was not significantly associated with rwOS (Hazard Ratio (HR) = 1.2, p = 0.2), rwPFS (Hazard Ratio (HR) = 0.9, p = 0.4), or rwTTNT (Hazard Ratio (HR) = 1.1, p = 0.6). Conclusion: Treatment sequence numerically favored R-T and provided an additional survival benefit of 2.6 months in this cohort, although this was not statistically significant. Providing access to regorafenib and FTD/TPI ± bevacizumab is critical to maximizing patient benefit and optimizing patient care in advanced stages of mCRC.
