Pré-habilitação funcional do membro superior da mulher mastectomizada / Functional prehabilitation of the upper limb in mastectomised women

Enquadramento: O cancro da mama afeta milhares de mulheres em todo o mundo não sendo Portugal uma exceção. No nosso país, todos os anos, são realizados milhares de diagnósticos de neoplasia maligna da mama. O tratamento cirúrgico é o mais frequente sendo que em muitos dos casos se recorre à mastectomia. Esta acarreta consigo possíveis complicações e morbilidades que poderão acompanhar o doente toda a vida. Os EEER são capazes de identificar situações potenciadoras de limitação e atuar no sentido de as minimizar e/ou evitar assentando num paradigma de pré-habilitação. Posto isto, nasceu a questão de partida: Quais os contributos da Enfermagem de Reabilitação na funcionalidade do membro superior homolateral na mulher mastectomizada? Objetivo: Identificar os contributos da Enfermagem de Reabilitação na funcionalidade do membro superior homolateral da mulher mastectomizada Metodologia: Trata-se de um estudo do tipo quantitativo, exploratório-descritivo, longitudinal com uma abordagem multicasos utilizando como instrumento de colheita de dados a escala DASH e um questionário sociodemográfico e clínico. A amostra (N=8) foi obtida recorrendo a uma técnica de amostragem não probabilística, por conveniência. Resultados: A média de idade das participantes foi de 49,6 ± 9,5. Após a implementação do programa de enfermagem de reabilitação metade da amostra (50%) referiu algum tipo de dificuldade em trocar uma lâmpada acima da cabeça, ainda assim uma percentagem significativa (37,5%) não teve qualquer dificuldade e apenas uma participante foi incapaz de o fazer. A maioria das participantes (62,5%) sentiram-se pouco ou nada limitadas na sua atividade laboral e nas AVD's. e apenas 37,5% consideraram que limitou ou limitou muito. No que diz respeito ao impacto nas atividades de lazer apenas uma participante (12,5%) se sentiu verdadeiramente afetada neste âmbito considerando as restantes 87,5% que pouco ou nada foram afetadas. Verificamos que nenhuma das participantes apresentou níveis elevados de dor, quer de uma forma geral quer na execução de uma atividade específica. Relativamente à fraqueza e à rigidez no braço, ombro ou mão, apesar de terem sofrido um agravamento quando comparamos o primeiro com o segundo momento de avaliação, 75% e 100% respetivamente, percecionaram pouco ou nada estes sintomas na segunda avaliação. Conclusão: A aplicação do programa de enfermagem de reabilitação "Pré-habilitar na Mastectomia" pareceu ter contribuído para minorar os efeitos da mastectomia e melhorar a sensação de formigueiro.

Background: Breast cancer affects thousands of women around the world, with Portugal being no exception. In our country, every year, thousands of breast cancers are diagnosed. Surgical treatment is the most common, and in many cases mastectomies are performed. This surgery is associated to a list of possible complications and morbidities that may accompany the patient throughout their lives. Rehabilitation nurses are capable of identifying situations that may cause limitations and act to minimize and/or avoid them based on a prehabilitation paradigm. Having said this, the following question arose: What are the contributions of Rehabilitation Nursing to the functionality of the homolateral upper limb of mastectomized women? Objective: To identify the contributions of Rehabilitation Nursing to the functionality of the homolateral upper limb of mastectomized women. Methodology: This is a quantitative, exploratory-descriptive, longitudinal study developed with a multi-case approach using the DASH scale and a sociodemografic and clinical questionnaire as a data collection instrument. The sample (N=8) was obtained using a non-probabilistic sampling technique, by convenience. Results: The mean age of the participants was 49,6 ± 9,5. After implementing the rehabilitation nursing program half of the sample (50%) reported some type of difficulty in changing a light bulb above their head, yet a significant percentage (37,5%) did not have any difficulty and only one participant was unable to do so. The majority of participants (62,5%) felt little or no limitations at their jobs or daily activities and only 37,5% consider that it limited or limited a lot. With regard to the impact on leisure activities, only one participant (12,5%) felt truly affected in this aspect, considering the remaining 87,5% that they were little or not affected at all. We found that none of the participants presented high levels of pain either in general or when carrying out a specific activity. In regards to the weakness and stiffness of the arm, shoulder or hand, despite having worsened when comparing the first and second assessments, in both, the majority of the sample, 75% and 100% respectively noticed these symptoms little or nothing at all on our second evaluation. Conclusion: The application of the rehabilitation nursing program "Prehabilitation in Mastectomy" appears to have contributed to lessening the effects of mastectomy and improving the tingling sensation.

Efectos de la mastectomía en los parámetros baropodométricos de pacientes con cáncer de seno / The effect of mastectomy on baropodometric parameters for breast cancer patients / Efeitos da mastectomia nos parâmetros baropodometricos de pacientes com câncer de mama

Objetivo: la mastectomía posterior al cáncer de seno produce diversas alteraciones posturales y biomecánicas en el plano frontal y sagital. Dichos cambios conducen a una cinemática alterada de la columna vertebral, desequilibrio muscular y alteración del soporte del peso del pie. Este estudio pretende describir las alteraciones de la baropodometría después de la mastectomía, con base en análisis baropodométricos de la presión media y la carga estática. Metodología: se realizó un estudio descriptivo correlacional. Las propiedades de carga del pie se identificaron en 17 mujeres mastectomizadas. Se utilizó una placa de presión Ecosanit Foot para medir la carga del pie en posición anatómica y con los pies juntos. Resultados: en el estudio participaron 17 mujeres mastectomizadas con una edad media de 54.16 años. Las pacientes reportaron una presión media significativamente mayor en la posición anatómica del lado dominante mastectomizado en comparación con el lado no dominante mastectomizado (227.2 ± 22.16 vs. 175.6 ± 14.95, p =0.05). No hubo diferencia significativa para la carga estática entre el lado dominante mastectomizado y el lado no dominante mastectomizado en la posición anatómica (52.43±4.069 vs. 49.69 ± 4.094, de forma respectiva). Conclusión: los resultados actuales de nuestro estudio evidenciaron la distribución desequilibrada del peso (vector carga en el pie) en pacientes después de la mastectomía. Por tanto, en este texto se describen las alteraciones posturales, musculares, y el desequilibrio estático y dinámico en pacientes con cáncer de seno.

Objective: mastectomy after breast cancer produces several postural and biomechanical alterations in the frontal and sagittal plane. Such changes lead to disturbed kinematics of the spine, muscle imbalance and altered foot weight bearing. This study aims to describe body balance alterations after mastectomy based on the baropodometric analysis of their mean pressure and static load. Methodology: a descriptive correlational research was carried out. Foot weight-bearing properties were identified in 17 patients who have undergone a mastectomy. An Ecosanit Foot pressure plate was used to measure foot load at anatomical position and keeping the feet together. Results: 17 female patients who had undergo mastectomy with a mean age of 54.16 years took part on the research. Patients who have had a dominant-side mastectomy demonstrated significant greater mean pressure at anatomical position when compared to those patients who have had a non-dominant side mastectomy (227.2 ± 22.16 versus 175.6 ± 14.95, p =0.05). There was no significant difference for static load between the patients who have had a dominant side mastectomy and patients who have had a non dominant side mastectomy at anatomical position (52.43 ± 4.069 versus 49.69 ± 4.094, respectively). Conclusion: the current results of our research showed the unbalanced weight distribution in patients after mastectomy. Consequently, it describes the postural and muscular alterations, and the static and dynamic imbalance in breast cancer patients.

Objetivo: A mastectomia após câncer de mama produz diversas alterações posturais e biomecânicas nos planos frontal e sagital. Tais mudanças levam a alteração da cinemática da coluna, desequilíbrio muscular e alteração do suporte de peso do pé. Este estudo tem como objetivo descrever as alterações baropodométricas após mastectomia, com base em análises baropodométricas de pressão média e carga estática. Metodologia: foi realizado estudo correlacional descritivo. Propriedades de carga nos pés foram identificadas em 17 mulheres mastectomizadas. Uma placa de pressão Ecosanit Foot foi usada para medir a carga do pé em posição anatômica e com os pés juntos. Resultados: participaram do estudo 17 mulheres mastectomizadas com idade média de 54,16 anos. Os pacientes relataram uma pressão média significativamente maior na posição anatômica do lado mastectomizado dominante em comparação ao lado mastectomizado não dominante (227,2 ± 22,16 vs. 175,6 ± 14,95, p =0,05). Não houve diferença significativa para a carga estática entre o lado mastectomizado dominante e o lado mastectomizado não dominante na posição anatômica (52,43 ± 4,069 vs. 49,69 ± 4,094, respectivamente). Conclusão: Os resultados atuais do nosso estudo mostraram distribuição de peso desequilibrada (carga vetorial no pé) em pacientes após mastectomia. Portanto, este texto descreve alterações posturais, musculares e desequilíbrio estático e dinâmico em pacientes com câncer de mama.

Postmastectomy analgesia with subcutaneous infiltration of ketamine with lidocaine in surgical wound. / Analgesia postmastectomía con infiltración subcutánea en herida quirúrgica de ketamina con lidocaína

Background: Ketamine is an analgesic adjuvant useful in acute pain preventive treatment. However, there are few studies evaluating its efficacy in local administration for postoperative pain management. Objective: To compare ketamine´s efficacy plus 2% lidocaine versus placebo plus 2% lidocaine infiltrated into surgical wound as postoperative analgesia in patients undergoing mastectomy. Material and methods: An experimental, randomized, single-blind study was carried out in 18 patients older than 18 years scheduled for mastectomy under general anesthetic technique. The surgical wound was infiltrated before to its closure with 0.5 mg/kg of ketamine plus 10 mL of simple 2% lidocaine volumetric to 20 mL with saline solution (group 1) or 10 mL saline solution + 10 mL of simple 2% lidocaine (group 2). Each patient was randomly assigned to one of the two intervention groups by draw (from which a piece of paper was drawn indicating the group to which they would belong). The pain intensity was assessed by Analog Numerical Scale (ANS) at 2, 8 and 12 hours after surgery and the need for analgesic rescue doses. Results: The scores on the ANS scale in both groups were similar at leaving (p 0.26) and 2 hours later (p 0.05). The ENA value was lower with 2% ketamine/lidocaine infiltration at 8 hours (ketamine 2.5 [2-3]; placebo 4 [3-7], p 0.01) and 12 hours (ketamine 3 [1-5]; placebo 5 [4-6], p < 0.001). Conclusions: Ketamine infiltrated into the surgical wound provides superior analgesia and improves ENA scores in the post-surgical period.

Introducción: la ketamina es un fármaco ahorrador de opioides y adyuvante analgésico, útil en el tratamiento preventivo del dolor agudo postoperatorio. Sin embargo, existen pocos estudios que evalúen su eficacia en su administración local para el manejo de dolor postoperatorio. Objetivo: comparar la eficacia de la ketamina más lidocaína al 2% frente a placebo más lidocaína al 2% infiltrada en herida quirúrgica como analgesia postoperatoria en pacientes sometidas a cirugía de mama. Material y métodos: se realizó un estudio experimental, prospectivo y aleatorizado en 18 pacientes mayores de 18 años programadas para mastectomía bajo técnica anestésica general. El sitio quirúrgico se infiltró con 0.5 mg/kg de ketamina más 10 mL de lidocaína al 2% aforado a 20 mL con solución salina (grupo 1) o solución salina 10 mL + 10 mL de lidocaína simple al 2% (grupo 2). Se valoró la intensidad del dolor mediante la Escala Numérica Análoga (ENA) a las 2, 8, y 12 horas posteriores a la cirugía y la necesidad de dosis de rescate analgésico. Resultados: las puntuaciones en la ENA en ambos grupos fueron similares al salir (p 0.26) y 2 horas posteriores (p 0.05). El valor de la ENA fue menor con la infiltración de ketamina/lidocaína 2% a las 8 horas (ketamina 2.5 [2-3]; placebo 4 [3-7], p 0.01) y 12 horas (ketamina 3 [1-5]; placebo 5 [4-6], p < 0.001). Conclusiones: la ketamina infiltrada en la herida quirúrgica provee analgesia superior, brinda seguridad y mejora las puntuaciones de la ENA en el periodo postquirúrgico.

Hipertermia maligna en paciente sometida a mastectomía radical tipo Madden / Malignant hyperthermia in a patient undergoing Madden type radical mastectomy

Resumen: El objetivo del presente estudio es dar a conocer el manejo anestésico que se proporcionó ante un evento crítico hipertermia maligna (HM) en una mastectomía radical Madden programada de manera electiva, la cual fue manejada con lo que se contaba en ese momento por no tener el fármaco específico (dantroleno) para este tipo de evento HM. El cáncer de mama es una enfermedad compleja, es la primera causa de muerte en la mujer a nivel mundial, ocurre en 70% en países desarrollados. México se encuentra en un nivel intermedio, representa un problema de salud con tendencia a la alta debido al envejecimiento de la población y a mayor prevalencia en factores de riesgo. La HM es un trastorno farmacogenético desencadenado por anestésicos que liberan una masiva acumulación de calcio en el sarcoplasma, que conduce a un metabolismo acelerado y a un incremento en la actividad contráctil del musculoesquelético, llevando a un estado hipermetabólico que genera un incremento en la temperatura corporal llegando a tener secuelas importantes y una alta mortalidad. Se trató de paciente femenino 40 años sin antecedentes relevantes para procedimientos anestésicos, se aplicó anestesia general balanceada, a los 60 minutos presentó datos clínicos que nos sugerían hipertermia maligna, fue manejada con los medios disponibles y se obtuvo un resultado favorable desde el punto de vista de morbimortalidad.

Abstract: The objective of the present is to present the anesthetic management that occurred before a critical event malignant hyperthermia HM) in an electively scheduled Madden radical mastectomy and which was managed with what was available at that time for not having the drug specific (dantrolene) for this type of event HM. Breast cancer is a complex disease, being the leading cause of death in women worldwide, with 70% occurring in developed countries. Mexico is at an intermediate level, being a health problem with a tendency to rise due to the aging of the population. population and higher prevalence of risk factors. Malignant hyperthermia (MH) is an anesthetic-triggered pharmacogenetic disorder that triggers a massive accumulation of calcium in the sarcoplasm, leading to accelerated metabolism and increased skeletal muscle contractile activity. Leading to a hypermetabolic state showing an increase in body temperature, leading to significant sequelae and high mortality. It was a 40-year-old female with no relevant history for anesthetic procedures, being managed with balanced general anesthesia at 60 minutes present data clinicians that they suggested malignant hyperthermia, being managed. With the available means, obtaining a favorable result from the point of view of morbidity and mortality.

Conclusion: It is necessary to establish oncological reference centers, guaranteeing individualized treatment and breast reconstruction.

Mastectomia en pacientes transgénero con hipertrofia mamaria, ¿existe una técnica ideal? Revisión narrativa / Mastectomy in transgender patients with breast hypertrophy: does an ideal technique exist? A narrative review

Introducción y objetivo: La cirugía de masculinización del tórax, también conocida como top surgery en inglés, es uno de los principales tratamientos quirúrgicos en la transición de género de mujer a hombre. Esta revisión tiene como objetivo describir las técnicas utilizadas para mastectomía en pacientes transgénero con hipertrofia mamaria y valorar ventajas y desventajas de las mismas. Material y método: Revisión narrativa mediante búsqueda en Pub-Med, Google Scholar y SciELO con las palabras clave: identidad de género, hipertrofia, mastectomía, en español, inglés y portugués. Seleccionamos para el análisis únicamente aquellos artículos que incluían masculinización de tórax en pacientes con hipertrofia mamaria. Resultados: La principal técnica mencionada fue la incisión doble transversa con injerto de complejo areola-pezón (CAP), que permite un amplio campo operatorio, tratamiento del surco submamario, reposicionamiento del CAP con precisión y dentro de sus variantes logra el tratamiento de la redundancia cutánea lateral. Otra opción de resección cutánea emplea el patrón de Wise que determina cicatriz en T invertida, difícil de ocultar. Se prefiere el tratamiento del CAP mediante injerto por lograr un tórax más plano en comparación al tratamiento con CAP pediculado. La satisfacción de los pacientes no fue medida de forma estandarizada, lo que dificulta la comparación. Conclusiones: Si bien no identificamos una técnica ideal aplicable universalmente, pudimos sintetizar ventajas y desventajas de cada una, brindando una guía orientadora para la toma de decisiones.Nivel de evidencia científica 5c Terapéutico.(AU)

Background and objective: Masculinizing chest surgery, or top surgery, is one of the main surgical treatments in the gender transition from female to male. This review aims to describe the mastectomy techniques in transgender patients with mammary hypertrophy and assess the advantages and disadvantages of each one. Methods: A narrative review was conducted through a search on Pub-Med, Google Scholar, and SciELO using the keywords: gender identity, hypertrophy, mastectomy, transgender persons, in Spanish, English, and Portuguese. Only articles that included masculinization of the chest in patients with mammary hypertrophy were selected for analysis. Results: The primary technique mentioned was the double transverse incision with the use of nipple-areola-complex (NAC) graft, which allows a wide operative field, treatment of the submammary groove, precise repositioning of the NAC, and, in its variants, the treatment of lateral skin redundancy. Another option for skin resection is the Wise pattern, which results in an inverted T-shaped scar difficult to conceal. Treating the NAC through grafting it is preferred to achieve a flatter chest compared to treatment with a pedicled NAC. Patient satisfaction was not standardized, making it difficult to compare outcomes. Conclusions: Although we did not identify an ideal technique universally applicable, we were able to synthesize the advantages and disadvantages of each technique providing a guiding framework in decision-making.Level of evidence 5c Terapeutic.(AU)

Introducción y objetivo: la mastectomía y la reconstrucción mamaria son procedimientos que forman parte del manejo multidisciplinario del cáncer de mama. Actualmente, se dispone del cuestionario BREAST-Q el cual permite determinar de manera objetiva y numérica la calidad de vida y la satisfacción de las pacientes que han recibido cirugías de mama. Se evaluaron las repercusiones de la reconstrucción mamaria posmastectomía con resultados inconsistentes, así mismo no existen investigaciones similares en la población peruana. El objetivo del presente estudio es determinar y comparar el nivel de satisfacción y la calidad de vida en las pacientes con cáncer de mama que recibieron una mastectomía con y sin reconstrucción mamaria. Material y métodos: estudio observacional, analítico de corte transversal realizado en las pacientes mastectomizadas por cáncer de mama con y sin reconstrucción mamaria del Centro Oncológico Aliada en Lima, Perú. Se incluyeron 46 pacientes operadas entre 2016 y 2021. La calidad de vida y la satisfacción de las pacientes se evaluó mediante el cuestionario BREAST-Q. Resultados: se obtuvieron diferencias significativas en las escalas de satisfacción con el pecho y de bienestar sexual al comparar a las pacientes mastectomizadas con y sin reconstrucción de mama, en donde el grupo con reconstrucción reflejó un mejor resultado en la satisfacción y la calidad de vida. No se observaron resultados significativos en las escalas de atención del equipo médico, eventos adversos de radiación y según el tipo de reconstrucción mamaria. Conclusiones: El instrumento BREAST-Q demostró que las pacientes que recibieron la reconstrucción mamaria obtuvieron mejores resultados en las escalas de satisfacción y calidad de vida en comparación a las pacientes sin reconstrucción mamaria. (AU)

Introduction and objective: Mastectomy and breast reconstruction are procedures that are part of the multidisciplinary management of breast cancer. Currently, the BREAST-Q questionnaire is available, which allows objective and numerical determination of the quality of life and satisfaction of patients who have undergone breast surgery. Studies have evaluated the repercussions of post-mastectomy breast reconstruction with inconsistent results, likewise there are no similar investigations in the Peruvian population. The objective of the present study is to determine and compare the level of satisfaction and quality of life in patients with breast cancer who underwent mastectomy with and without breast reconstruction. Material and methods: Observational, analytical cross-sectional study carried out in patients with mastectomies for breast cancer with and without breast reconstruction at the Aliada Oncology Center, Lima-Peru. 46 patients operated between the years 2016-2021 were included. The quality of life and satisfaction of the patients was evaluated using the BREAST-Q questionnaire. Results: Significant differences were obtained in the breast satisfaction and sexual well-being scales when comparing mastectomy patients with and without breast reconstruction, where the group with reconstruction reflected a better result in satisfaction and quality of life. No significant results were obtained in the scales of attention of the medical team, adverse events of radiation and according to the type of breast reconstruction. Conclusions: The BREAST-Q instrument showed that patients undergoing breast reconstruction obtained better results on the satisfaction and quality of life scales compared to patients without breast reconstruction.

Mastectomía e injerto cutáneo autólogo por fascitis necrotizante torácica / Mastectomy and skin graft as treatment for thoracic necrotizing fasciitis

Se presenta el caso de una paciente fumadora con hipertensión arterial, diabetes mellitus tipo II en tratamiento con insulina, con control glucémico inadecuado, HS y dislipidemia que ingresó por infección en la mama y la pared torácica izquierda con progresión a fascitis necrotizante. Se intentó inicialmente una actitud quirúrgica conservadora, pero dado el mal control de sus enfermedades de base y la infección rápidamente progresiva, requirió desbridamiento más agresivo con mastectomía y exéresis de músculo afecto. Posteriormente, se realizó un injerto cutáneo mallado en la zona de mastectomía izquierda con zona donante de muslo izquierdo. A pesar de la gravedad del caso, con el tratamiento quirúrgico extenso, antibióticos de amplio espectro y curas diarias, la paciente superó el cuadro séptico y se limitó de ese modo la progresión de la infección. En controles posteriores, la paciente presentó buena evolución clínica. (AU)

Hidradenitis suppurativa is an inflammatory skin disease that affects the folliculopilosebaceous unit. Necrotizing fasciitis of the thoracic wall is a rare entity that affects subcutaneous tissue and deep fascia. It represents a diagnostic and therapeutic emergency requiring broad spectrum antibiotics and extense surgical debridement, with high mortality rates. Other reported cases do not describe fascitis as an infection complicating hidradenitis, as the case of our patient. We present a case of a patient with a history of hidradenitis suppurativa, smoking, hypertension, diabetes mellitus with poor glycemic control, and dyslipidemia, admitted to our hospital with left breast and thoracic wall infection, with progression to necrotizing fascitis. Initially a preservative surgery was attempted but given the patient's comorbidities and the rapidly progressive infection, a mastectomy was required. In second time surgery, an autologous skin graft was performed. Despite the severity of the case, the patient overcame the infection after extensive surgical debridement, broad spectrum antibiotics and daily cures. In follow-up controls the patient presented good clinical condition. (AU)

Mastectomía libre de opioides bajo anestesia-analgesia epidural torácica en un paciente con estenosis traqueal crítica: caso clínico / Opioid-free mastectomy under thoracic epidural anesthesia-analgesia in a patient with critical tracheal stenosis: A case report

Mastectomy is traditionally performed under general anaesthesia and invasive ventilation, and is often complemented with regional techniques. In this setting, tracheal stenosis can pose a challenge to airway management. The aim of this report is to describe the successful management of a 68-year-old woman with severe subglottic tracheal stenosis undergoing mastectomy due to breast cancer. Surgery was performed without airway instrumentation under an opioid-free regimen consisting of thoracic epidural, propofol and dexmedetomidine perfusion, and non-opioid analgesics. Spontaneous ventilation and adequate perioperative analgesia were achieved. Opioid-free anaesthesia without airway instrumentation, consisting of thoracic epidural anaesthesia and sedation, is a good alternative in patients undergoing mastectomy in whom airway manipulation is best avoided.(AU)

La mastectomía se realiza tradicionalmente bajo anestesia general y ventilación invasiva, complementándose a menudo con técnicas regionales. En este contexto, la estenosis traqueal puede suponer un reto para el manejo de la vía aérea. El objetivo de este informe es describir el manejo exitoso de una mujer de 68 años de edad con estenosis traqueal subglótica severa, sometida a mastectomía debido a cáncer de mama. La cirugía se realizó sin instrumentación de la vía aérea bajo un régimen libre de opioides consistente en epidural torácica, propofol y perfusión de dexmedetomidina, y analgésicos no opioides, lográndose ventilación espontánea y analgesia perioperatoria adecuada. La anestesia libre de opioides sin instrumentación de la vía aérea, consistente en anestesia epidural torácica y sedación, es una buena alternativa en pacientes sometidos a mastectomía, en los que es mejor evitar la manipulación de la vía aérea.(AU)

Prevalencia de complicaciones en pacientes mastectomizadas por cáncer de mama

Introducción: la mujer de hoy exige una cirugía lo más efectiva, segura y estética posible. Objetivo: determinar la prevalencia de las complicaciones posquirúrgicas en pacientes mastectomizadas por cáncer de mama. Materiales y métodos: se realizó un estudio cuantitativo, observacional y descriptivo en un universo de 137 pacientes sometidas a mastectomía, por cáncer de mama comprobado histológicamente, en 2019, en los hospitales General Provincial Carlos Manuel de Céspedes y Clínico Quirúrgico Docente Celia Sánchez Manduley, de Granma. Se evaluaron las variables edad, extensión de la mastectomía, lateralidad, aparición de complicaciones, tipo de complicación, estadio tumoral y diagnóstico histológico. Resultados: la media de edad de las pacientes mastectomizadas fue de 56,53 años, y la mastectomía radical modificada fue el proceder quirúrgico más realizado (76 mamas). La incidencia de complicaciones fue del 52,17 % (1,24 % intraoperatoria), siendo la complicación de mayor prevalencia el linfedema (29,63 %). En relación con el tipo histológico, el carcinoma ductal infiltrante sin especificar (77,54 %) fue el más frecuente, y con los estadios tumorales, el IIIB (22,46 %) y el IV (22,46 %) fueron los de mayor prevalencia. La incidencia de las complicaciones aumentó en la medida en que se elevó el estadio tumoral. Conclusiones: la incidencia de las complicaciones posquirúrgicas en la mastectomía fue elevada, relacionándose con el estadio tumoral.

Introduction: today's woman demands the most effective, secure and esthetic surgery possible. Objective: to determine the prevalence of post-surgery complications in patients mastectomized by breast cancer Materials and methods: a quantitative, observational and descriptive study was carried out in a universe of 137 patients who underwent a mastectomy by histologically proven breast cancer, in 2019, in the General Provincial Hospital Carlos Manuel de Cespedes and in the Clinical Surgical Teaching Hospital Celia Sanchez Manduley, of Granma. The variables age, extension of mastectomy, laterality, appearance of complications; type of complication, tumoral stage and histologic diagnosis were evaluated. Results: the mean age of mastectomized patients was 56.53 years, and modified radical mastectomy was the most performed procedure (76 mammae). The incidence of complications was 52.17% (1.24% intra-operatory), being lymphedema (29.63%) the most prevalent complication. In relation to the histologic type, unspecified infiltrating ductal carcinoma (77.54%) was the most frequent one, and tumoral stages IIIB (22.46%) and IV (22.46%) were the most prevalent. The incidence of complications increased as the tumor stage increased. Conclusions: the incidence of postsurgical complications in mastectomy was high, in relation with the tumor stage.

Opioid-free mastectomy under thoracic epidural anesthesia-analgesia in a patient with critical tracheal stenosis: a case report.

Mastectomy is traditionally performed under general anaesthesia and invasive ventilation, and is often complemented with regional techniques. In this setting, tracheal stenosis can pose a challenge to airway management. The aim of this report is to describe the successful management of a 68-year-old woman with severe subglottic tracheal stenosis undergoing mastectomy due to breast cancer. Surgery was performed without airway instrumentation under an opioid-free regimen consisting of thoracic epidural, propofol and dexmedetomidine perfusion, and non-opioid analgesics. Spontaneous ventilation and adequate perioperative analgesia were achieved. Opioid-free anaesthesia without airway instrumentation, consisting of thoracic epidural anaesthesia and sedation, is a good alternative in patients undergoing mastectomy in whom airway manipulation is best avoided.

Reconstrucción mamaria inmediata mediante implante prepectoral de poliuretano. Resultados preliminares del estudio prospectivo PreQ-20 / Immediate breast reconstruction by prepectoral polyurethane implant: Preliminary results of the prospective study PreQ-20

Introducción: Durante los últimos años las técnicas de mastectomía y reconstrucción han evolucionado hacia procedimientos menos agresivos, mejorando la satisfacción y calidad de vida de la mujer. Por ello, la mastectomía se ha convertido en una opción válida tanto para mujeres con cáncer de mama como en mujeres de alto riesgo. El objetivo de este estudio es analizar la seguridad de la mastectomía y reconstrucción inmediata prepectoral con implante de poliuretano en mujeres con cáncer de mama y reducción de riesgo. Métodos: Estudio prospectivo observacional para evaluar la factibilidad y seguridad de la reconstrucción inmediata mediante implante prepectoral de poliuretano. Se incluyeron todas las mujeres (con cáncer de mama o alto riesgo para cáncer de mama) intervenidas mediante una mastectomía preservadora de piel o piel y pezón con reconstrucción inmediata con implante de poliuretano prepectoral. Se excluyeron las mujeres con sarcomas de mama, progresión de la enfermedad durante el tratamiento sistémico primario, reconstrucción diferida, autóloga o retropectoral y aquellas pacientes que no desearon participar en el estudio. Los procedimientos quirúrgicos fueron realizados tanto por cirujanos senior como junior. Todas las pacientes recibieron los tratamientos complementarios correspondientes. Se analizaron todos los eventos adversos acontecidos durante el seguimiento y los factores de riesgo para desarrollarlos. Resultados: Se realizaron 159 reconstrucciones en 102 mujeres, el 80,4% por un carcinoma mamario. Catorce pacientes desarrollaron complicaciones, siendo el seroma y la dehiscencia de la herida las más frecuentes. Ocho mujeres precisaron una reintervención (5%), 7 de ellas por exposición del implante. Cuatro reconstrucciones (2,5%) culminaron con pérdida del implante. Tres pacientes presentaron progresión de su proceso oncológico: una recaída local en el colgajo de la mastectomía, una progresión axilar y una progresión sistémica. (AU)

Introduction: In recent years, mastectomy and reconstruction techniques have evolved towards less aggressive procedures, improving the satisfaction and quality of life of women. For this reason, mastectomy has become a valid option for both women with breast cancer and high-risk women. The objective of this study is to analyze the safety of mastectomy and immediate prepectoral reconstruction with polyurethane implant in women with breast cancer and risk reduction. Method: Observational prospective study to evaluate the feasibility and safety of immediate reconstruction using prepectoral polyurethane implant. All women (with breast cancer or high risk for breast cancer) who underwent skin-sparing or skin-and-nipple-sparing mastectomy with immediate reconstruction with a prepectoral polyurethane implant were included. Women with breast sarcomas, disease progression during primary systemic therapy, delayed, autologous or retropectoral reconstruction, and those who did not wish to participate in the study were excluded. Surgical procedures were performed by both senior and junior surgeons. All patients received the corresponding complementary treatments. All adverse events that occurred during follow-up and the risk factors for developing them were analyzed. Results: 159 reconstructions were performed in 102 women, 80.4% due to breast carcinoma. Fourteen patients developed complications, the most frequent being seroma and wound dehiscence. Eight women required a reoperation (5.0%), seven of them due to implant exposure. Four reconstructions (2.5%) resulted in loss of the implant. Three patients progressed from their oncological process: a local relapse in the mastectomy flap, an axillary progression and a systemic progression. (AU)

Recaídas locorregionales tras mastectomías preservadoras y reconstrucción inmediata en mujeres con cáncer de mama / Locoregional relapse after sparing mastectomies and immediate reconstruction in women with breast cancer

Introducción: Durante los últimos años, los cambios culturales de la sociedad actual y la mejora en la valoración del riesgo han incrementado la indicación de las mastectomías en mujeres con cáncer de mama. Diversos estudios han confirmado la seguridad oncológica de la mastectomías preservadoras y reconstrucción inmediata. El objetivo de este estudio es analizar la incidencia de recaídas locorregionales de este procedimiento y su impacto en la reconstrucción y la supervivencia global. Pacientes y métodos: Estudio prospectivo de pacientes con un carcinoma de mama que realizaron una mastectomía preservadora y reconstrucción inmediata. Se analizaron las recaídas locorregionales, el tratamiento de las mismas y la capacidad de preservar la reconstrucción, así como su impacto en la supervivencia. Resultados: El grupo a estudio lo constituyen 271 mujeres con carcinoma mamario tratadas mediante una mastectomía ahorradora de piel y reconstrucción inmediata. El seguimiento medio fue de 7,98 años y durante el mismo se diagnosticaron 18 recaídas locorregionales (6,6%): 72,2% en el colgajo de la mastectomía y 27,8% ganglionares. No se evidenciaron diferencias significativas en las características patológicas del tumor primario entre las pacientes con y sin una recaída locorregional, aunque el porcentaje de mujeres con tumores hormonosensibles fue superior en el grupo sin recaída. Las pacientes con recaída ganglionar presentaban tumores de mayor tamaño (el 80% T2-T3) y el 60% tenían metástasis axilares al diagnóstico vs. 7,7% de las mujeres con recaída en piel (p = 0,047). Todas las pacientes intervenidas de una recaída locorregional preservaron su reconstrucción. La incidencia de metástasis y muertes fue significativamente mayor en las pacientes con una recaída, causando una disminución no significativa de la supervivencia global. (AU)

Introduction: In recent years, cultural changes in today's society and improved risk assessment have increased the indication for mastectomies in women with breast cancer. Various studies have confirmed the oncological safety of sparing mastectomies and immediate reconstruction. The objective of this study is to analyze the incidence of locoregional relapses of this procedure and its impact on reconstruction and overall survival. Patients and methods: Prospective study of patients with breast carcinoma who underwent a sparing mastectomy and immediate reconstruction. Locoregional relapses and their treatment and their impact on survival were analyzed. Results: The study group is made up of 271 women with breast carcinoma treated with a skin-sparing mastectomy and immediate reconstruction. The mean follow-up was 7.98 years and during the same 18 locoregional relapses (6.6%) were diagnosed: 72.2% in the mastectomy flap and 27.8% lymph node. There were no significant differences in the pathological characteristics of the primary tumor between patients with and without locoregional relapse, although the percentage of women with hormone-sensitive tumors was higher in the group without relapse. Patients with lymph node relapse had larger tumors (80% T2–T3) and 60% had axillary metastases at diagnosis, compared to 7.7% of women with skin relapse (p = 0.047). All patients operated on for locoregional relapse preserved their reconstruction. The incidence of metastases and deaths was significantly higher in patients with a relapse, causing a non-significant decrease in overall survival. (AU)

All women (with breast cancer or high risk for breast cancer) who underwent skin-sparing or skin-and-nipple-sparing mastectomy with immediate reconstruction with a prepectoral polyurethane implant were included. Women with breast sarcomas, disease progression during primary systemic therapy (PST), delayed, autologous or retropectoral reconstruction, and those who did not wish to participate in the study were excluded. Surgical procedures were performed by both senior and junior surgeons. All patients received the corresponding complementary treatments. All adverse events that occurred during follow-up and the risk factors for developing them were analyzed. RESULTS: 159 reconstructions were performed in 102 women, 80.4% due to breast carcinoma. Fourteen patients developed complications, the most frequent being seroma and wound dehiscence. Eight women required a reoperation (5.0%), seven of them due to implant exposure. Four reconstructions (2.5%) resulted in loss of the implant. Three patients progressed from their oncological process: a local relapse in the mastectomy flap, an axillary progression and a systemic progression. CONCLUSIONS: Prepectoral reconstruction with a polyurethane implant is a procedure with a low incidence of postoperative complications (8.8%) and implant loss (2.5%). Its use is safe with perioperative cancer treatments (neoadjuvant chemotherapy and radiotherapy).

Oncological safety of nipple-sparing mastectomy after neoadjuvant chemotherapy: a systematic review / Segurança oncológica da mastectomia conservadora do mamilo após quimioterapia neoadjuvante: revisão sistemática

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.
