Abstract | ABSTRACT Background: the use of nipple-sparing mastectomy (NSM) in local advanced breast cancer after neoadjuvant chemotherapy (NQT) is increasing, despite few studies on the subject. The aim of this systematic review was to determine the safety of NSM after neoadjuvant chemotherapy. Methods: for this systematic review we searched MEDLINE; Cochrane; Scientific Electronic Library Online (SciELO); Embase and Scopus. A literature search of all original studies including randomized controlled trials, cohort studies and case-control studies comparing women undergoing NSM after neoadjuvant chemotherapy for breast cancer was undertaken. Outcomes were locoregional recurrence (LRR), nipple recurrence and distant recurrence (DR). Data analysis was undertaken to explore the safety of NSM after NQT. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO, number CRD42021276778. Findings: a total of 437 articles were identified. Four articles were included with 1466 patients all of which had a high to serious risk of overall bias. Local recurrence in the NSM after the NQT group ranged from zero to 9.8%. Nippleareolar complex (NAC) recurrence ranged from zero to 2.1%. The distant recurrence rate ranged from 6.5% to 16%. Due to the lack of pattern among the control groups, it was not possible to perform a meta-analysis. Interpretation: this review provides information for decision making in performing NSM after NQT. Despite the low rates of local recurrence and patients should be counseled about limited oncological information.
RESUMO Introdução: O uso de mastectomia preservadora de complexo aréolo-papilar (MPCAP) no câncer de mama localmente avançado após quimioterapia neoadjuvante (QTN) é crescente, apesar de ainda haver poucos estudos abordando o assunto. O objetivo desta revisão sistemática foi determinar a segurança da MPCAP após a quimioterapia neoadjuvante. Métodos: para esta revisão sistemática, pesquisamos no MEDLINE; Cochrane; Scientific Electronic Library Online (SciELO); Embase e Scopus. Foi realizada uma busca na literatura de todos os estudos originais, incluindo ensaios clínicos randomizados, estudos de coorte e estudos de caso-controle comparando mulheres submetidas a MPCAP após quimioterapia neoadjuvante para câncer de mama. Os desfechos foram recorrência locorregional, recidiva em papila e recorrência à distância. A análise dos dados foi realizada para avaliar a segurança da mastectomia preservadora de complexo aréolo-papilar após o QTN. A qualidade da evidência foi avaliada com a ferramenta de avaliação de risco de viés da Cochrane - ROBINS-I. Este estudo está registrado no PROSPERO, número CRD42021276778. Resultados: Um total de 437 artigos foram identificados. Quatro artigos foram incluídos na análise, totalizando 1466 pacientes, todos com risco de viés geral moderado a alto. A recorrência local no grupo MPCAP após QTN variou de zero a 9,8%. A recorrência no complexo aréolo-papilar (CAP) variou de zero a 2,1%. A taxa de recorrência à distância variou de 6,5% a 16%. Devido à falta de padrão entre os grupos de controle, não foi possível realizar uma meta-análise. Interpretação: esta revisão fornece informações para a tomada de decisão na realização de NSM após QTN. Apesar das baixas taxas de recorrência local, os pacientes devem ser orientados sobre as informações oncológicas limitadas. |
