Tumor size is associated with adjuvant chemotherapy benefit in T1N0M0 triple-negative breast cancer: a multicenter and propensity score matched 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
Background: Triple-negative breast cancer (TNBC) is characterized by aggressive phonotypes and relatively poor outcomes. There are controversies on the effect of adjuvant chemotherapy in small (T1N0M0) TNBCs, especially among T1a-b patients. This study evaluated the survival benefit of adjuvant chemotherapy and influential factors in T1N0M0 TNBC patients. Methods: All T1N0M0 TNBC patients were identified from the Shanghai Jiao Tong University Breast Cancer Database (SJTU-BCDB) between January 2009 and December 2021. Propensity score matched (PSM) was applied to create a matched cohort. We used Kaplan-Meier analysis and Cox regression models to evaluate the associations of adjuvant chemotherapy with breast cancer-free interval (BCFI) and overall survival (OS). Stratified analysis according to different influential factors was also performed. Results: In total, 1,113 T1N0M0 TNBC patients (297 T1a, T1b and 816 T1c) were enrolled, including 928 patients with adjuvant chemotherapy and 185 patients without adjuvant chemotherapy. After matching 441 patients by using PSM analysis, 294 patients with chemotherapy and 147 patients without chemotherapy were identified. Patients with or without chemotherapy had similar BCFI (P=0.241) and OS (P=0.509). However, regarding patients with different tumor sizes, adjuvant chemotherapy could significantly improve BCFI in T1c patients (5-year BCFI: 92.1% Conclusions: The survival benefit of adjuvant chemotherapy was significantly associated with tumor size in T1N0M0 TNBC. Benefit of adjuvant chemotherapy was found in T1c, but not in T1a-b patients. Our findings do not support the routine use of chemotherapy in patients with T1a-bN0 TNBC.
