Long-term outcomes of skin-sparing mastectomy and nipple-sparing mastectomy versus traditional mastectomy in breast cancer: a case-control study based on preoperative ultrasound and clinical indicators.
Article in World journal of surgical 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
BACKGROUND AND
objectiveNipple-sparing mastectomy (NSM) and skin-sparing mastectomy (SSM) are recognized for their aesthetic benefits in breast cancer patients. However, detailed evaluations with large samples of their long-term oncological effectiveness are limited. This study aims to compare the long-term oncologic outcomes of NSM/SSM and traditional mastectomy (TM) in patients with stage I-III breast cancer and to identify influential preoperative factors.
methodsAmong the 12,802 breast cancer patients who underwent surgery from 2009 to 2022 in West China Hospital of Sichuan University, 295 NSM/SSM patients and 584 TM patients were selected after propensity score matching adjusted for variables. Survival outcomes were analyzed using Kaplan-Meier estimates, Fisher's exact test, and log-rank tests, with Cox regression identifying survival predictors.
resultsThe median follow-up period was 97.93 months. Local recurrence (LR) was 5.76 ± 1.36% for NSM/SSM compared to 3.25 ± 0.73% for TM (p = 0.076). Overall survival (OS) was comparable (p = 0.601), while disease-free survival (DFS) showed a trend toward significance (p = 0.066). However, there was a significant difference in distant metastasis-free survival (DMFS) (p = 0.029). The 5-year OS rates between the matched groups were similar (98.11% vs. 98.09%, p = 1.000), while the TM group exhibited higher 5-year DFS(95.14% vs. 92.03%, p = 0.335). Following the univariate analysis, multivariate analysis identified significant DFS predictors: stage (HR = 2.701, p = 0.031), radiotherapy (HR = 1.928, p = 0.018), and targeted therapy (HR = 5.584, p < 0.001). For OS, significant predictors included stage (HR = 8.309, p = 0.021) and PR status (HR = 0.35, p = 0.010).
conclusionsNSM/SSM demonstrated comparable OS and DFS to TM, though with lower DMFS. Preoperative ultrasound parameters showed no significant impact on long-term outcomes, confirming the oncologic safety of NSM/SSM. Tailored adjuvant therapies and appropriate follow-up may further optimize patient prognoses.
