Introduction: The number of breast reconstructions after breast cancer is increasing over the years. This study evaluates complications in the first 30 days after breast reconstruction post mastectomy in different surgical techniques for patients with non-metastatic breast cancer.
Methods: Retrospective cohort including patients who underwent breast reconstruction post mastectomy at the National Institute of Neoplastic Diseases (INEN) 2014-2018. Outcomes were immediate complications (first 30 days after surgery). Cumulative incidences were obtained. Association with clinical and demographic factors was evaluated using adjusted relative risk (aRR) obtained via Poisson Regression with robust variances.
Results: 2092 patients had mastectomy at INEN during the study period, but only 271 underwent breast reconstruction. From them, 148 had complete data and fulfilled the selection criteria. Median age was 45 years old, 62.16% had overweight/obesity, and 35.85% had clinical stage III. 28.38% had immediate autologous reconstruction, 33.11% immediate prosthetic reconstruction, and 38.51% delayed reconstruction of any type. 48.65% had some surgical complication in the first 30 days, being the most frequent dehiscence (20.27%) and superficial infection (18.92%). Overweight/Obesity (aRR 1.96; 1.24-3.10) and having immediate reconstruction (aRR 1.54; 1.04-2.27) were associated to complications. Prosthetic technique use was protective (aRR 0.59; 0.40-0.85), as well as Neoadjuvant Chemotherapy (aRR 0.65; 0.42-0.99).
Conclusions: The prosthetic surgical technique had less early complication incidence than the autologous one. On the other hand, immediate surgery after mastectomy was more likely to present complications compared with delaying. Variables as obesity, neoadjuvant therapy and ECOG intervened in the incidence of complications. === Introducción: El número de reconstrucciones mamarias post cáncer de mama ha ido en aumento. Este estudio evalúa las complicaciones en los primeros 30 días luego de reconstrucción mamaria post mastectomía para cáncer de mama no metastásico en sus diferentes técnicas quirúrgicas.
Métodos: Cohorte retrospectiva de pacientes con reconstrucción mamaria post mastectomía en el Instituto Nacional de Enfermedades Neoplásicas (INEN) entre 2014-2018. Los desenlaces fueron las complicaciones quirúrgicas en los 30 días siguientes a la cirugía. Se obtuvieron incidencias acumuladas, y se evaluó su asociación con diversos factores clínico-demográficos mediante riesgos relativos crudos y ajustados (aRR) obtenidos vía Regresión de Poisson con varianza robusta.
Resultados: De 2092 pacientes que tuvieron mastectomía en el INEN entre 2014-2018, solo 271 tuvieron reconstrucción mamaria. De ellas 148 tuvieron datos completos y cumplieron los criterios de selección. La mediana de edad fue 45 años, 62.16% tuvieron sobrepeso/obesidad, y 35.85% tenían estadio clínico III. El 28.38% tuvieron reconstrucción inmediata autóloga, 33.11% reconstrucción inmediata usando prótesis, y 38.51% reconstrucción tardía. El 48.65% de los pacientes experimentó alguna complicación en el mes siguiente post cirugía, siendo las complicaciones más frecuentes dehiscencia de sutura (20.27%) e infección superficial (18.92%). Obesidad (RR 1.96; 1.24-3.10), y tener Técnica Inmediata (RR 1.54; 1.04-2.27) se asociaron a más complicaciones. Uso de Técnica Protésica fue protector (RR 0.59; 0.40-0.85), así como también Quimioterapia Neoadyuvante (RR 0.65; 0.42-0.99).
Conclusiones: La técnica quirúrgica protésica tuvo menos probabilidades de presentar complicaciones que la autóloga. Asimismo, la cirugía inmediata presenta más probabilidades de presentar complicaciones que la diferida. Las variables como obesidad, terapia neoadyuvante y ECOG intervienen en la presentación de complicaciones. === Tesis |
