Docetaxel rechallenge in HER2-negative metastatic breast cancer: a real-world study of previously discontinued patients for non-progression reasons.
Article in Journal of cancer research and clinical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeThis study aimed to evaluate the efficacy and safety of docetaxel rechallenge in HER2-negative metastatic breast cancer (MBC) patients who discontinued docetaxel for reasons other than disease progression. PATIENTS AND
methodsWe retrospectively analyzed HER2-negative MBC patients treated with docetaxel-based therapy (DBT) at our institution from 2010 to 2020. Objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were assessed. Multivariate Cox regression and propensity score matching analysis (PSMA) were used to minimize bias.
resultsAmong 600 patients, 369 only received docetaxel once (control group), while 231 (38.5%) received docetaxel rechallenge as second or later-line therapy (rechallenge group). In the second-line rechallenge subset (143 patients), ORR was 51.0%, and PFS was 6.7 months. Multivariate analysis showed that a response to initial DBT (stable disease [SD] vs. complete response/partial response [CR/PR]: odds ratio [OR] 2.615, 95% confidence interval [CI] 1.373-4.981; p = 0.03) independently predicted the ORR. Beyond second-line rechallenge, the ORR and PFS were 37.5% and 5.6 months, respectively. After PSMA, the rechallenge group demonstrated significantly improved OS compared to the control group: 50.5 months vs. 46.0 months (Hazard Ratio [HR] 0.632; 95% CI 0.455-0.878; p = 0.006). The toxicities reported were manageable, primarily hematologic, with grade 3-4 events occurring in 19.5% of cases.
conclusionThis study suggests that docetaxel rechallenge may be an effective and tolerable later-line treatment option for patients with HER2-negative MBC, particularly those who responded to initial DBT. However, further prospective, randomized controlled research is needed to fully evaluate its impact on disease response in this patient population.
