RESUMEN
Immunotherapies have been a treatment proposed for recurrent miscarriages (RMs). The use of immunotherapies remains not recommended in the management of couples with RM. This overview of systematic reviews and meta-analysis (SRs-MAs) aims to identify and evaluate the quality of SRs-MAs that studied the effectiveness of immunotherapies in the treatment of RM patients. SRs-MAs were searched in PubMed/Medline, Embase, and Web of Science. SRs-MAs were analyzed using AMSTAR-2, PRISMA 2020, Risk of Bias in Systematic (ROBIS), and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tools to evaluate the methodological quality, reporting quality, risk of bias, and evidence quality of included SRs-MAs, respectively. This review included 20 SRs-MAs that evaluated the following immunotherapies: intravenous immunoglobulin (13 publications), lymphocyte immunotherapy (6 publications), corticosteroids (3 publications), and lipid emulsion (1 publication). SRs-MAs were rated as high methodological, moderate, and critically low quality in 14 (70 %), 1 (5 %), and 5 (25 %) SRs-MAs and high reporting, moderate, and low quality in 13 (65 %), 4 (20 %), and 3 (5 %) SRs-MAs, respectively. The overall risk of bias revealed a low risk of bias for three-quarters of the SRs-MAs. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) analysis resulted in 23 outcomes, of which 4, 3, 5, and 11 results were of high, moderate, low, and very low quality, respectively. An improvement has been observed over the past few years in the quality of systematic reviews (SR)-MAs that have investigated the efficacy of intravenous immunoglobulin, lymphocyte immunotherapy, lipid emulsion therapy, and corticosteroids as a therapy for RM.

INTRODUCTION: Axillary lymph node involvement is recognized as a key prognostic factor for invasive breast cancer. Retrospective analyzes have shown that extracapsular extension (ECE) is correlated with negative prognostic factors in this neoplasia. OBJECTIVE: to evaluate the measurement of ECE and its relationship with the number of affected non-sentinel lymph nodes, as well as to investigate the association between ECE with other clinical and pathological prognostic factors. METHODS: This is a cross-sectional observational study carried out from January 2015 to June 2019, at the Breast Surgical Oncology service of Liga Contra o Cancer (LIGA), in Natal, Brazil. A total of 150 patients were included in the study and were divided into three groups: absence of ECE, ECE less than or equal to 2 mm and ECE greater than 2 mm. RESULTS: The mean age was 58 years for the group with ECE and 57 years for the group without ECE. Most of the patients were mixed race (66.7%), had no family history of breast cancer (64%) and underwent quadrantectomy (64.5%). Regarding the characteristics of the disease, most presented a histological report compatible with Invasive Carcinoma of the non-special type (IC NST) (87.5%), histological grade II (52.7%), negative Lymphovascular invasion (LVI) (52.7%), Tumor Size T1 (<2.0 cm) (52%) and Luminal B molecular subtype (36.7%). Regarding sentinel lymph nodes: 103 patients (68.7%) had ECE and 1 positive sentinel lymph node was identified in most cases. There was a statistically significant association between the presence of ECE and of being mixed race (p = 0.03), between ECE and LVI (p = 0.05) and between ECE and a greater number of positive non-sentinel lymph nodes (p < 0.001). CONCLUSION: Our study showed that ECE> 2 mm is associated with increased axillary nodal load compared to groups without ECE and ECE ≤ 2 mm in sentinel node biopsy in patients who met the Z0011 criteria.
