Real-World Outcome and Prognostic Factors Among HER2-Positive Metastatic Breast Cancer Patients Receiving Pyrotinib-Based Therapy: A Multicenter Retrospective 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
Purpose: To explore the efficacy, safety, and potential factors influencing efficacy and outcome of pyrotinib-based therapy in human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) in complex clinical practice. Methods: Real-world data for HER2-positive MBC patients treated with pyrotinib-based regimens from 6 hospitals in Northern Anhui, China, from September 2018 to February 2022, were retrospectively collected, and clinicopathological features, efficacy, prognosis, and safety were analyzed. Potential influencing factors including baseline serum vascular endothelial growth factor-A (VEGF-A) for evaluating pyrotinib's treatment response and outcome were also explored. Results: A total of 169 patients with HER2-positive MBC were enrolled. The objective response rate (ORR), disease control rate (DCR), and median progression-free survival (mPFS) of the overall cohort were 65.1%, 87.6%, and 12.4 months, respectively. Pyrotinib is highly beneficial as different treatment lines and appears to be a feasible strategy both in combination with chemotherapeutic drugs and alone. The mPFS values were 16.5 months, 12.4 months, and 9.3 months in the first, second, and third-or-higher lines of anti-HER2 therapy, respectively ( Conclusion: Pyrotinib-based regimens showed promising efficacy, with manageable tolerance, and AE occurrence of severe diarrhea and baseline level of serum VEGF-A are helpful in predicting the treatment outcome of pyrotinib in HER2-positive MBC.
