Abstract
Introduction

Immediate breast reconstruction (IBR) after skin-sparing mastectomy in patients undergoing neoadjuvant chemotherapy (NACT) is still controversial. The objective is to determine related factors to the axillary downstaging and complete pathological response (CPR), and how CPR influences the decision of bilateral mastectomy with immediate reduction (IBRBM).

Patients and methods

A retrospective analysis breast cancer patients undergoing NACT and IBRBM between 2000–2018 was performed. We compared two groups;1)CPR and 2) not CPR. Descriptive and comparative statistical analysis.

Results and Discussion

69 patients; 26 (37.68%) reached CPR and 43 (62.32%) non-CPR. Median follow-up of 45.3 months (RIQ:23,0–94,0). Age less than 35 (p < 0.001), small size tumor at diagnosis (p = 0.006) and subtype HER2 (p < 0.001) were associated with higher rates of CPR in univariate analysis. Axillary negativization rate was 80% in group 1 and 59.3% in group 2 and lymphadenectomy rates were similar (73.1% and 83.72%).

Conclusion

CPR after NACT not conditioned the decision to perform IBRBM.

Resumen
Introducción

La reconstrucción mamaria inmediata (RMI)tras mastectomías ahorradoras de piel en pacientes sometidas a quimioterapia neoadyuvante(QTNA) todavía resulta controvertida. El objetivo es determinar factores relacionados con downstaging axilar y respuesta patológica completa (RPC), y como esta, condiciona la decisión de someterse a mastectomía bilateral con reconstrucción inmediata (MBRMI).

Pacientes y Métodos

Se realizó un análisis retrospectivo de pacientes con cáncer de mama sometidas a QTNA y MBRMI entre 2000–2018.Comparamos dos grupos; 1)RPC y2) no RPC. Se analizaron datos demográficos, anatomopatológicos y el estadio clínico inicial y final. Análisis estadístico descriptivo y comparativo.

Resultados y Discusión

69 pacientes; Grupo1:26 (37,68%) alcanzaron RPC y 43(62,32%) no RPC. Mediana de seguimiento 45,3meses (RIQ:23,0-94,0. En análisis univariante, edad menor a 35 p < 0,001, menor T al diagnósticop = 0,006 y subtipo HER2 p < 0,001 se asociaron significativamente con mayores tasas de RPC. La indicación más frecuente fue la elección de la paciente 31,8%. La tasa de negativización axilar fue del 80% en el grupo 1 y 59.3% en grupo 2 y las tasas de linfadenectomía axilar fueron similares (73.1% y 83.72 %).

Conclusión

La RPC tras la QTNA no parece ser un factor de peso en la decisión de realizar la MBRMI
