Efficacy and safety of utidelone in pretreated patients with metastatic breast cancer in China: a multicenter, real-world study.

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: Utidelone (UTD1), a genetically engineered epothilone derivative, has been approved in China for use in combination with capecitabine in treating metastatic breast cancer (MBC) patients previously treated with anthracyclines or taxanes. Objectives: To evaluate the real-world efficacy and safety of UTD1 in Chinese patients with MBC and to explore potential predictors of therapeutic effectiveness. Design: A multicenter, retrospective, real-world study. Methods: MBC patients who received UTD1 between March 2021 and August 2023 were identified using an electronic database. Outcome variables included progression-free survival (PFS), overall survival (OS), time to treatment failure (TTF), objective response rate (ORR), clinical benefit rate (CBR), and adverse events (AEs). Results: A total of 270 MBC patients were included, with 81.1% presenting with visceral metastasis and 23.7% with brain metastasis. The median number of treatment lines for UTD1 was 3. UTD1 showed a median PFS of 3.97 months (95% confidence interval (CI) 3.33-4.61) and a median OS of 20.63 months (95% CI 16.72-24.54). Among the patients, 17.4% received UTD1 monotherapy, and 82.6% received UTD1-based combination therapy. The median TTF was 2.80 months (95% CI 2.31-3.29). The ORR was 8.4%, and the CBR was 33.5%. The most common AE was peripheral neuropathy (PN, 55.2%). Patients with unresolved PN from previous therapy or receiving UTD1 through intravenous infusion on days 1-5 were more likely to develop ⩾grade 3 PN. Conclusion: UTD1 is a new option for patients who have previously received taxanes and anthracyclines, with its clinical toxicity controllable.
