Impact of lymph node status on the prognosis of female breast cancer patients who underwent immediate reconstruction after total mastectomy: a multi-institutional retrospective cohort 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
purposeThis study aims to evaluate the impact of lymph node status on survival outcomes in female breast cancer patients underwent immediate breast reconstruction (IBR) after mastectomy.
methodsData from 8418 cases (2010-2017) receiving IBR were divided into regional lymph node negative (LN-) and positive (LN+) groups. Propensity score matching (PSM) was used to balance covariates between groups. Subgroup Cox regression analysis was performed to assess overall survival (OS) and breast cancer-specific survival (BCSS), considering sociodemographic, oncological, and treatment-related factors.
resultsInpatients underwent IBR, the LN+ group exhibited significantly poorer OS and BCSS than the LN- group, both before and after PSM. Higher income, specific tumor characteristics, and implant-based reconstruction were related to better survival outcomes. Subgroup analysis revealed that in LN- group, lower income, HR-, HER2- status, and higher tumor grade were OS/BCSS risk factors. In the LN+ group, advanced T stage independently predicted worse OS/BCSS, and contralateral breast removal was associated with a decrease in OS risk.
conclusionsCaution is warranted when recommending IBR for patients with N2-3, and implant-based reconstruction may represent a more favorable option in selected cases. LN+ status is a significant adverse prognostic factor in IBR patients. Personalized treatment strategies based on LN status are essential for optimizing survival outcomes.
