Clinical and biomarker predictors of early and late recurrence in hormone receptor-positive breast cancer.
Article in BMC cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHormone receptor-positive (HR+) breast cancer (BC) is characterized by a persistent risk of recurrence that continues for decades. Although many factors have been linked to recurrence, the clinical features associated with late relapse and patterns of distant metastases are less understood. Our study aimed to identify factors associated with early (< 5 years) and late (5–10 years) recurrence in a real-world cohort of HR+/human epidermal growth factor receptor type2-negative (HER2-) BC patients.
methodsOur study performed a retrospective analysis of stage I-III HR+/HER2- BC cases diagnosed between 1981 and 2022. Assessed variables included metastatic sites, early and late invasive recurrences.
resultsA total of 4,367 women with HR+/HER2- were included; 81.2% were stage I/II, 41,4% had nodal involvement; 42.0% received neoadjuvant chemotherapy and 94.0% adjuvant endocrine therapy (ET). Five- and ten-year invasive disease-free survival (iDFS) rates were 85.0% and 70.0%, respectively. Of the 847 invasive events (19.4%), 54.3% were early and 45.7% late recurrences. Compared with late recurrences, early recurrences were associated with fewer stage I tumors, higher nodal involvement, higher grade, and elevated Ki-67. In multivariate analysis, higher stage was the only independent factor linked to both early and late recurrence; older age correlated with late relapse. Distant metastases occurred in 70.2% of recurrences and were associated with higher tumor burden, grade 3, and elevated Ki-67; 47.5% involved visceral sites.
conclusionLate recurrences may occur even in patients clinically classified as low risk. Early recurrences reflect higher tumor burden and proliferative activity, with implications for treatment and follow-up strategies.
