Reconstrucción mamaria con TRAM bipediculado. Variantes utilizadas y resultados obtenidos / Breast reconstruction with bipedicled TRAM. Variants used and results obtained

La reconstrucción mamaria utilizando el colgajo TRAM (transverse rectus abdominis muscle) bipediculado es un procedimiento poco frecuente aunque en ciertas ocasiones es de gran utilidad. Las indicaciones principales están descriptas para los casos que se requieren volúmenes de tejidos de mayor cantidad que la reconstrucción mamaria convencional, antecedentes de irradiación de grandes zonas de la pared del tórax y, en ciertas ocasiones, en reconstrucciones mamarias autólogas bilaterales. La presente publicación revisa el uso de 12 colgajos TRAM bipediculados en nuestra institución, las variantes que hemos usado y los resultados obtenidos. También se detallan elementos anatómicos de interés técnico con el objeto de reducir las complicaciones.

Breast reconstruction using the bipedicle TRAM (transverse rectus abdominis muscle) flap is a rare procedure, although it is sometimes very useful. The main indications are described for cases that require larger tissue volumes than conventional breast reconstruction, a history of irradiation of large areas of the chest wall, and on certain occasions, in bilateral autologous breast reconstructions. This publication reviews the use of 12 bipedicle TRAM flaps in our institution, the variants that we have used, and the results obtained. Anatomical elements of technical interest are also detailed to reduce complications.

Feasibility study of immediate breast reconstruction with fusion fascia combined with implants / 中华肿瘤杂志

Objective: To investigate the oncologic and surgical safety of the fused fascia method for immediate breast reconstruction with implants. Methods: The clinical data of 343 patients with immediate breast reconstruction with implants in Tianjin Medical University Cancer Hospital from 2014-2017 were retrospectively analyzed to compare the 5-year local recurrence-free survival, 5-year disease-free survival and 5-year overall survival of patients with breast reconstruction by fusion fascia and other methods, and to analyze the complication incidences of implant removal between different implant groups. Results: Of the 343 patients with breast reconstruction, 95 were in the fused fascia group (fascia group) and 248 were in the non-fascia group (25 in the bovine pericardial patch group and 223 in the muscle flap group). At a median follow-up of 49 months, the differences in 5-year local recurrence-free survival (90.1% and 94.9%, respectively), 5-year disease-free survival (89.2% and 87.6%, respectively), and 5-year overall survival (95.2% and 95.1%, respectively) between patients in the fascial and non-fascial groups were not statistically significant (P>0.05). The complication incidence of implant removal was 24.0% (6/25) in the patch group and 2.1% (2/95) and 2.2% (5/223) in the fascia and muscle flap groups, respectively. Conclusion: Immediate breast reconstruction with fused fascial combined with implant is safe and feasible, less invasive than muscle flaps, more economical and with fewer complications than patches.

Aesthetic assessment of breast reconstruction in the eyes of plastic surgeons versus nonplastic physicians

SUMMARY OBJECTIVE: The aim of this study was to evaluate the perception of the aesthetic result of breast reconstruction surgery from the perspective of plastic surgeons compared with physicians who are not specialists in plastic surgery. METHODS: Twenty patients who underwent breast reconstruction after mastectomy had their aesthetic results evaluated by 16 plastic surgeons and 16 nonplastic physicians, yielding a total of 620 ratings (320 ratings from plastic surgeons and 320 ratings from other specialists). For all analyses, the level of rejection adopted for the null hypothesis was 5% (p-value <0.05). RESULTS: Significant differences were observed between the two groups. On average, medical professionals who specialized in plastic surgery always obtained higher scores than other physicians. However, no significant differences were found in the assessment of the aesthetic outcome of breast reconstruction according to the sex of the rating medical professional for any of the assessments considered in this study. A strong positive linear correlation between the time since training in the medical specialty of plastic surgery (r=0.750, p=0.001) and the mean aesthetic outcome score was observed in this study. CONCLUSION: Plastic surgeons assessed the aesthetic results of breast reconstruction more positively than nonplastic physicians.

Factors influencing decisions on contralateral symmetrisation procedure among patients with breast cancer

INTRODUCTION@#Oncoplastic breast-conserving surgery (OBCS) can cause breast asymmetry. Although contralateral breast surgery to achieve symmetry was offered to these patients, the uptake of symmetrisation was variable. We aimed to determine the factors that deter patients with breast cancer undergoing OBCS from opting for symmetrisation.@*METHODS@#All patients with breast cancer who underwent OBCS of displacement type with no symmetrisation were prospectively surveyed to explore the social, economic, psychological and physical reasons against symmetrisation.@*RESULTS@#A total of 28 patients participated in a survey administered at a mean 21.6 (range 2-47) months after OBCS. A combination of factors, such as worry and desire to treat breast cancer first (67.9%), not being overly concerned about breast cosmesis (57.1%) and fear of pain from additional operation (28.6%), deterred patients from immediate symmetrisation. Worry and desire to treat breast cancer first was the most important single factor for 50% of the patients. Reasons for no delayed symmetrisation included not being overly concerned about breast cosmesis (70.4%), fear of breast cancer recurrence (48.1%) and being happy with current breast cosmesis (33.3%), with the former two reasons equally cited as the single most important deterrent by 30% of patients each.@*CONCLUSION@#A combination of factors may deter patients from symmetrisation. The most significant factors deterring OBCS among patients were worry and desire to treat breast cancer first for immediate symmetrisation, and not being overly concerned about breast cosmesis and fear of breast cancer recurrence for delayed symmetrisation. Reassuring these patients may increase their uptake of symmetrisation, thereby improving patient cosmesis and satisfaction.

Incision selection for nipple-sparing mastectomy with implant-based breast reconstruction / 中华外科杂志

Objective: To examine the outcome of different incision selection for nipple-sparing mastectomy (NSM) with implant-based breast reconstruction (IBBR). Methods: Ninety-Two cases accepted NSM and IBBR from totally 1 002 cases of breast cancer admitted to Beijing Tongren Hospital Affiliated to Capital Medical University from June 2013 to December 2020 were analyzed retrospectively. All the patients were female, aging (42.0±7.5) years (range: 27 to 64 years). There were 12 patients at stage 0, 47 patients at stage Ⅰ, 17 patients at stage Ⅱ, and 16 patients at stage Ⅲ. The patients were divided in three groups by the incision: peri-areolar group (n=23), inframammary group (n=33) and lateral group (n=36). The age, tumor size, lymph node status, hormone receptor, operation method and postoperative complications were followed-up of three groups and compared by one-way ANOVA, χ2 test or Fisher's exact test and expansion to comparied. Results: There was no significant difference in operation time ((180.7±54.0) minutes vs. (176.9±48.1) minutes vs. (194.6±37.5) minutes, F=1.401, P=0.252), postoperative drainage volume ((497.5±226.0) ml vs. (495.4±182.5) ml vs. (519.8±172.0) ml, F=0.167, P=0.846) and drainage time ((8.8±3.8) days vs. (8.0±2.5) days vs. (8.3±2.9) days, F=0.542, P=0.583) among the peri-areolar, inframammary, and lateral groups. The cumulative postoperative complications were relatively higher in the peri-areola group (26.1%(6/23) vs. 0 vs.8.3%(3/36), χ²=9.675, P=0.004). All female patients were followed up for (49.0±25.6) months(range: 12 to 112 months). Breast cancer related death rate was 2.2% (2/92), local recurrence was 1.1% (1/92), regional recurrence was 4.3% (4/92), distant metastasis was 6.5% (6/92), and the disease-free survival rate was 88.0% (81/92). Conclusion: The surgical effects of the peri-areolar, inframammary and lateral incisions for NSM and IBBR are approximate, the total complication rate of the peri-areolar incision is slightly higher.

Application of acellular bovine pericardium patch in implant based immediate breast reconstruction / 中华外科杂志

Objective: To examine the clinical effect of acellular bovine pericardium patch in implant based immediate breast reconstruction. Methods: The clinicopathological information of 141 breast cancer patients, who admitted to Department of Breast Reconstruction and Oncoplastic Surgery, Tianjin Medical University Cancer Hospital, underwent immediate mammoplasty with implants combined with acellular bovine pericardium patches were analyzed from June 2016 to October 2019. All patients were female, with the age of (38.8±8.5) years (range: 13 to 60 years). The body mass index was (21.9±2.5) kg/m2 (range: 16.0 to 32.3 kg/m2). There were 39 cases of duct carcinoma in situ, 46 cases of stage Ⅰ, 40 cases of stage Ⅱ and 16 cases of stage Ⅲ. All patients received nipple-areola-sparing mastectomy or skin-sparing mastectomy with sentinel lymph node biopsy or axillary lymph node dissection, and prosthesis implantation with sub-pectoralis combined with breast patch. The correlation of clinicopathological characters and complications was assessed by t test, χ2 test, Fisher's exact probability method and Logistic regression. Pre-and post-operative aesthetic, quality of life scores were recorded. Results: The operation time (M(IQR)) was 3.6(1.5) hours (range: 3.0 to 6.5 hours). The early postoperative complication rate was 22.0% (31/141), prosthesis removal was the main postoperative complication, accounting for 64.5% (20/31) of the total complications, of which 15 cases occurred in the first 30 patients. The follow-up time was 28(8) months (range: 20 to 53 months), The most frequent long-term complications were capsular contracture and implant displacement, with the incidence of 11.2% (14/125) and 10.4% (13/125), respectively. Multivariate analysis showed that prosthesis volume ≥300 ml (OR=8.173, 95%CI: 1.302 to 51.315, P=0.021) and peri-areolar incision (OR=7.809, 95%CI: 2.162 to 28.211, P<0.01) were independent relative factors for the occurrence of short-term postoperative local complications. After 2 years of operation, the score of breast appearance satisfaction was 71.7±15.5, postoperative effect satisfaction was 90.4±9.5, psychological satisfaction was 90.7±17.1, sexual satisfaction was 70.1±25.1. The immediate postoperative satisfaction rate at discharge was 95.4% (134/141), and 17.6% (22/125) of patients had the intention to received revision surgery. Conclusions: Prosthesis volume ≥300 ml and peri-areolar incision were independent realtive factors for short-term local complications after bovine pericardium patch combined with prosthesis implantation in the immediate breast reconstruction. After completing the learning curve, the postoperative complications of the procedure could be decreased.

Surgical management of nipple areola complex in central breast cancer / 中华肿瘤杂志

Objective: To explore the surgical strategy of nipple areola complex (NAC) management in central breast cancer. Methods: A retrospective analysis was conducted on 164 cases of central breast cancer who underwent surgery treatment from December 2017 to December 2020 in the Breast Center of Beijing Tongren Hospital, Capital Medical University. Prior to the surgery, the tumor-nipple distance (TND) and the maximum diameter of the tumor were measured by magnetic resonance imaging (MRI). The presence of nipple invagination, nipple discharge, and nipple ulceration (including nipple Paget's disease) were recorded accordingly. NAC was preserved in patients with TND≥0.5 cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative intraoperative frozen pathological margin. All patients with signs of NAC involvement, TND<0.5 cm or positive NAC basal resection margin confirmed by intraoperative frozen pathology underwent NAC removal. χ(2) test or Fisher exact test was used to analyze the influencing factors. Results: Of the 164 cases of central breast cancer, 73 cases underwent breast-conserving surgery, 43 cases underwent nipple-areola complex sparing mastectomy (NSM), 34 cases underwent total mastectomy, and the remaining 14 cases underwent skin sparing mastectomy (SSM). Among the 58 cases of NAC resection (including 34 cases of total mastectomy, 14 cases of SSM, and 10 cases of breast-conserving surgery), 25 cases were confirmed tumor involving NAC (total mastectomy in 12 cases, SSM in 9 cases, and breast-conserving surgery in 4 cases). The related factors of NAC involvement included TND (P=0.040) and nipple invagination (P=0.031). There were no correlations between tumor size (P=0.519), lymph node metastasis (P=0.847), bloody nipple discharge (P=0.742) and NAC involvement. During the follow-up period of 12 to 48 months, there was 1 case of local recurrence and 3 cases of distant metastasis. Conclusions: For central breast cancer, data suggest that patients with TND≥0.5cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative NAC margin in intraoperative frozen pathology should be treated with NAC preservation surgery, whereas for those with TND<0.5 cm or accompanied by signs of NAC invasion, NAC should be removed. In addition, nipple reconstruction can be selected to further improve the postoperative appearance of patients with central breast cancer.

Background: Lipograft breast augmentation has increased due to avoidance of prosthetics. It is used for moderate increases for aesthetic purposes, it does not delay the diagnosis of cancer or increase the risk of suffering it. Aim: To review our experience in cosmetic breast augmentation with lipograft, in one session and with a follow-up of more than one year. Materials and Method: A prospective cohort of women was designed. Those with congenital alterations, mesenchymopathies and smokers were excluded. Lipoinjection was carried out with Coleman's principies. The Breast-V application was used to measure preoperative breast volume. Volume of increase, retention rate and rate of increase were calculated. Results: 73 patients were lipografted, 35 had a one-year follow-up. Initial breast volume was 219.5 ± 44.1 cc. Volume increase was 99.9 ± 29.8 cc, grafted fat retention rate 41.4%, breast volume increase rate 48.1%. 41 patients presented postoperative images: cysts 15 patients (36.6%); fat necrosis 2 patients (4.9%); macrocalcifiations 8 patients (19.5%); microcalcifiations 1 patient (2.5%), whose biopsy was negative for malignancy. Discussion: The mammary lipograft is a safe procedure, with adequate results when performed in one session and by the same surgeon, following Coleman principles. The percentage increase is the most significant index to evalúate your success. Conclusions: Breast lipoinjection in one session is a safe technique that achieves a moderate increase in breast volume. It is useful for moderate magnification or correction of slight asymmetries. There is no evidence that it interferes with the early diagnosis of breast cancer.

Colgajo dorsal ancho por abordaje único vertical en el síndrome de Poland: caso clínico / Retalho latíssimo do dorso por abordagem único vertical na síndrome de Poland: caso clínico / Latissimus dorsi vertical single-approach flap in Poland syndrome: clinical case

El síndrome de Poland constituye una malformacion que asocia diversos grados de anomalia toracica y a nivel del miembro superior, con una incidencia de 1 cada 30000 nacidos vivos. Esta patologia geenra ausencia de la glandula mamaria y del musculo pectroral mayor como malformacion mas frecuente. Lo cual produce una asimetria a nivel de torax con perdida de la armonia la cual lleva a una alteracion tanto fisica como psicologica a nivel de la paciente. Por esto es necesario resolver esta patologia con la menor morbilidad posible. El planteo de generar la menor morbilidad nos llevo a realizar una tecnica por abordaje unico sub axilar, a traves del cual se diseca el musculo dorsal ancho y se transpone de forma anterior, obteniendo una sola incision, la cual se mantiene oculta debajo del miembro superior adducido. Produciendo menor tiempo operatorio, menor tiempo de internacion, disminuyendo el número de incsiones y logrando una adecuada fijacion anterior del musculo dorsal ancho.

Poland's syndrome is a malformation associated with varying degrees of thoracic and upper limb abnormality, with an incidence of 1 in 30,000 live births. This pathology generates the absence of the mammary gland and the major pectoral muscle as the most frequent malformation. Which produces an asymmetry at the chest level with loss of harmony which leads to both physical and psychological alteration at the level of the patient. For this reason, it is necessary to resolve this pathology with the least possible morbidity. The proposal to generate the least morbidity led us to perform a single sub axillary approach technique, through which the latissimus dorsi muscle is dissected and transposed anteriorly, obtaining a single incision, which is kept hidden under the upper limb adduced. Producing less operative time, shorter hospitalization time, reducing the number of incisions and achieving an adequate anterior fixation of the latissimus dorsi muscle.

A síndrome de Poland é uma malformação associada a vários graus de anomalia torácica e de membros superiores, com uma incidência de 1 em 30.000 nascidos vivos. Essa patologia gera a ausência da glândula mamária e do músculo pectoral principal como a malformação mais frequente. O que produz uma assimetria ao nível do peito com perda de harmonia que conduz a alterações físicas e psicológicas ao nível do paciente. Por isso, é necessário resolver essa patologia com a menor morbidade possível. A proposta de gerar o mínimo de morbidade nos levou a realizar uma única técnica de abordagem subaxilar, por meio da qual o músculo grande dorsal é dissecado e transposto anteriormente, obtendo-se uma única incisão, que é mantida escondida sob o membro superior. aduzido. Produzindo menos tempo operatório, menor tempo de internação, reduzindo o número de incisões e conseguindo uma fixação anterior adequada do músculo grande dorsal.

Reconstrucción mamaria inmediata en el Instituto Nacional de Oncología y Radiobiología de Cuba / Immediate Breast Reconstruction at the National Institute of Oncology and Radiobiology of Cuba

RESUMEN Introducción: La reconstrucción mamaria inmediata disminuye el impacto psicológico del cáncer de mama y mejora la calidad de vida de las pacientes. Objetivo: Evaluar la simetría en la reconstrucción mamaria inmediata en el Instituto Nacional de Oncología y Radiobiología de Cuba. Método: Se realizó un estudio analítico y prospectivo, de cohorte incidente, en el Servicio de Cirugía Reconstructiva del Instituto Nacional de Oncología y Radiobiología de 2014 al 2017. Se incluyeron 41 pacientes que consintieron participar en el estudio. Se recogieron variables demográficas y onco-reconstructivas. Se utilizó un software creado en la institución para evaluar la simetría mamaria. Los datos se recogieron de la historia clínica. Se aplicaron el test de Chi-cuadrado corregido y la razón de momios para el análisis estadístico. Resultados: El 30,2 por ciento de mujeres reconstruidas pertenecieron al grupo de 30 a 39 años; el 46,3 por ciento tenían sobrepeso. La mejor simetría se encontró con las técnicas oncoplásticas (31,7 por ciento), seguida de la mastectomía ahorradora de piel. La técnica de expansión tisular con la mastectomía presentó mayores complicaciones (63,6 por ciento) y menor simetría. La necrosis parcial de piel fue la mayor complicación en 7,3 por ciento y estuvo relacionadas con las técnicas ahorradoras de piel. Conclusiones: Evaluar de forma objetiva la simetría mamaria permitió conocer la efectividad de las técnicas quirúrgicas reconstructivas. Con las técnicas de cirugía oncoplástica y mastectomía ahorradora de piel se obtuvieron los mejores resultados estéticos y pocas complicaciones. La expansión mamaria inmediata con una mastectomía radical modificada no ofrece ninguna ventaja(AU)

ABSTRACT Introduction: Immediate breast reconstruction reduces the psychological impact of breast cancer and improves the quality of life of patients. Objective: To assess symmetry in immediate breast reconstruction at the of Cuba. Method: An analytical and prospective study of incident cohort was carried out in the reconstructive surgery service at the National Institute of Oncology and Radiobiology (INOR), from 2014 to 2017. Forty-one patients who consented to participate in the study were included. Demographic and oncoreconstructive variables were collected. A software created in the institution was used to assess breast symmetry. The data were collected from the medical histories. The corrected chi-square test and odds ratio were applied for statistical analysis. Results: 30.2 percent of women who received reconstruction belonged to the age group 30-39 years; 46.3 percent were overweight. The best symmetry was found with oncoplastic techniques (31.7 percent), followed by skin-sparing mastectomy. The tissue expansion technique with mastectomy presented greater complications (63.6 percent) and less symmetry. Partial skin necrosis was the major complication, accounting for 7.3 percent of the cases, and was related to skin-sparing techniques. Conclusions: Objectively evaluating breast symmetry allowed us to know the effectiveness of reconstructive surgical techniques. With oncoplastic surgery and skin-sparing mastectomy techniques, the best aesthetic outcomes and few complications were obtained. Immediate breast expansion with a modified radical mastectomy offers no benefit(AU)

RESUMEN Introducción: La reconstrucción mamaria por cáncer, mediante la técnica de expansión tisular es una técnica que proporciona piel de color, textura y sensibilidad naturales. Objetivo: Caracterizar la reconstrucción mamaria con el uso de expansores tisulares en el Instituto Nacional de Oncología y Radiobiología de Cuba. Método: Se realizó un estudio retrospectivo y longitudinal en el Servicio de Cirugía Reconstructiva del Instituto Nacional de Oncología y Radiobiología de Cuba del 2013 al 2017. La muestra de 93 pacientes se seleccionó de forma consecutiva del universo de pacientes. El análisis estadístico incluyó las pruebas de Chi-cuadrado, estimación de la razón de momios y regresión logística binaria, con nivel de significación p ≤ 0,05. Resultados: Predominó la reconstrucción en mujeres con un promedio de edad de 45,7 años, [IC95 por ciento (43,8-47,5) y desviación estándar 9.0]. La quimioterapia se administró a 74 pacientes y la radioterapia a 41. La reconstrucción diferida se realizó en el 51,6 por ciento de las cirugías, y en el 72,0 por ciento no se presentaron complicaciones. El cáncer en estadio III y el uso de quimioterapia y radioterapia neoadyuvante mostraron riesgo con significación estadística para las complicaciones posquirúrgicas. Conclusiones: La reconstrucción mamaria mediante el uso de expansores tisulares presentó características demográficas y clínicas similares a las descritas previamente en la población cubana y el resto del mundo, aunque con peculiaridades desde el punto de vista onco-reconstructivo. La realización de la cirugía reconstructiva inmediata luego de la radioterapia neoadyuvante resultó en un mayor riesgo de complicaciones(AU)

ABSTRACT Introduction: Breast reconstruction for cancer, using the tissue expansion technique, is a technique that provides skin of natural color, texture and sensitivity. Objective: To characterize breast reconstruction with the use of tissue expanders at the National Institute of Oncology and Radiobiology of Cuba. Method: A retrospective and longitudinal study was carried out in the Reconstructive Surgery Service of the National Institute of Oncology and Radiobiology of Cuba from 2013 to 2017. The sample of 93 patients was selected consecutively from the universe of patients. Statistical analysis included Chi-square tests, estimation of the odds ratio and binary logistic regression, with a significance level of p ≤ 0,05 Results: Reconstruction predominated in women with an average age of 45.7 years, [95 percent CI (43.8-47.5) and standard deviation 9.0]. Chemotherapy was administered to 74 patients and radiotherapy to 41. Delayed reconstruction was performed in 51.6 percent of the surgeries, and in 72.0 percent there were no complications. Stage III cancer and the use of neoadjuvant chemotherapy and radiotherapy showed a statistically significant risk for postoperative complications. Conclusions: Breast reconstruction by using tissue expanders presented demographic and clinical characteristics similar to those previously described in the Cuban population and the rest of the world, although with peculiarities from the onco-reconstructive point of view. Performing immediate reconstructive surgery after neoadjuvant radiation therapy resulted in an increased risk of complications(AU)

La mastectomía bilateral con reconstrucción inmediata en pacientes con cáncer de mama ¿retrasa el inicio de terapias adyuvantes? / Bilateral mastectomy with immediate reconstruction as a treatment for breast cancer: is it the cause of delays in adjuvant therapies?

Resumen Introducción El tratamiento estándar del cáncer de mama es la cirugía conservadora, aunque actualmente existe un incremento de cirugías más radicales, incluyendo reconstrucción. Estas técnicas, aparentemente más complejas, pueden suponer mayor índice de complicaciones y, por ende, mayor intervalo de tiempo entre la cirugía y el inicio de terapias adyuvantes, lo que puede condicionar peores resultados de los tratamientos, traducido en el índice de recidivas locales y/o sistémicas o incluso de las tasas de supervivencia. Objetivo Revisar si la mastectomía bilateral con reconstrucción inmediata (MBRI) supone un retraso en el inicio del tratamiento adyuvante (TA). Materiales y Método Análisis retrospectivo de pacientes con MBRI como tratamiento de cáncer. Variables principales: tiempo transcurrido entre la cirugía y el inicio de la TA, definiendo retraso como más de 90 días. Otras variables: datos del paciente, tipo de intervención, complicaciones. Se analizan datos por tipo de intervención y si presentaban cirugía conservadora previa. Resultados 296 pacientes con MBRI, 171 (57,7%) por cáncer de novo y 125 (42,3%) por neoplasia recidivada o un segundo primario (ipsi o contralateral). La tasa general de complicaciones fue de 21% y no difirió entre los grupos con y sin radioterapia previa (p 0,05). La técnica quirúrgica asociada a una tasa mayor de complicaciones fue el patrón corto de Wise. No hubo diferencias en el resto. No existió un retraso significativo mayor de 90 días en los grupos con o sin radioterapia, ni según la técnica quirúrgica. Conclusiones La MBRI no ocasiona retrasos significativos en el inicio de TA.

Background Breast conserving surgery is already the standard treatment of breast cancer although mastectomy and radical techniques including reconstruction are currently increasing. These techniques, apparently more complex, can develop more complications and delay adjuvant therapies initiation, conditioning worst results of treatments, with higher rates of local and/or systemic recurrences or even survival rates. Aim Review whether bilateral mastectomy with immediate reconstruction (MBRI) conditionate a delay in the initiation of adjuvant therapy (TA). Materials and Method A retrospective analysis of patients with MBRI as a cancer treatment. Main variable: Time to TA, was defined as the number of days between surgery and the first dose of chemotherapy or radiotherapy. Other variables: patient data, type of intervention and complications. We analyzed the data by type of intervention and if they had been previously treated from another breast tumor. Results In all, 296 patients with MBRI were included, 171 with a Cancer de novo and 125 already treated that now have a relapsed neoplasia or a second primary (IPSI or contralateral). Overall complication rate was 21%. Complication rate did not differ between groups either or neither previous radiotherapy. The surgical technique associated with a higher rate of complications was the short Wise pattern, with no differences in the others. There was no delay greater than 90 days in the groups with radiotherapy or without, or according to the surgical technique.

Resumen Introducción: El tumor Phyllodes mamario es una entidad muy poco frecuente, con tendencia a la recidiva local y una tasa de malignización de 5-10%. La base de su tratamiento es la resección quirúrgica. Material y Métodos: Mujer de 32 años diagnosticada de un tumor Phyllodes maligno en mama derecha sometida en otro centro a cirugía conservadora con colocación de expansor y a dos tumorectomías posteriores por recidiva local. Fue referida a nuestro Hospital al presentar una nueva recidiva de gran tamaño (9,2 cm) para valoración de intervención quirúrgica. Resultados: Se realizó exéresis del tumor (remanente de tejido mamario y músculo pectoral mayor) y retirada del expansor con reconstrucción mamaria con colgajo de dorsal ancho en el mismo tiempo quirúrgico. En el momento actual la paciente se encuentra pendiente de iniciar tratamiento radioterápico. Conclusiones: El tumor Phyllodes maligno es una entidad poco frecuente y cuyo manejo terapéutico se basa en la resección quirúrgica con márgenes. De forma adyuvante se puede administrar quimiorradioterapia. Es de gran importancia realizar un manejo multidisciplinar e individualizado de cada caso para ofrecer el mejor pronóstico.

Introduction: Phyllodes tumor is a rare entity, with a high tendency to local recurrence and a malignancy rate of 5-10%. The basis of its treatment is the surgical resection. Materials and Method: We report a 32-year-old woman who was diagnosed of a malignant Phyllodes tumor who had previously underwent conservative breast surgery and expander placement in another center. Two subsequent lumpectomies due to local recurrences were necessary. She was referred to our Hospital for she presented a new large-sized recurrence (9.2 cm) at the retroarelor area for assessment of new surgical treatment. Results: Surgical resection of the tumor (remnant of mammary tissue and pectoralis major muscle) and removal of the expander with immediate breast reconstruction with latissimus dorsi flap was performed. At the present time, the patient is pending radiotherapeutic treatment. Conclusions: Malignant Phyllodes tumor is a rare entity whose therapeutic management is based on margin-free surgical excision. Adjuvant chemoradiotherapy might be administered. It is very important to carry out a multidisciplinary and individualized management of each case to offer the best possible forecast.

Pioderma gangrenoso após mamoplastia redutora: desafios diagnóstico e terapêutico / Pyoderma gangrenosum after reduction mammoplasty: diagnostic and therapeutic challenges

O pioderma gangrenoso (PG) é doença inflamatória da pele, que pode se desenvolver espontaneamente, associado a certas doenças sistêmicas e neoplásicas, ou ao trauma cirúrgico, incluindo os das mamas. Há relatos cada vez mais frequentes, considerando o aumento desse procedimento nos dias atuais. A manifestação clínica das úlceras é característica e deve ser lembrada nas evoluções cicatriciais desfavoráveis com intensa reação inflamatória, perdas teciduais, secreção sanguinolenta e/ ou purulenta, fundo granuloso e bordas elevadas. Relatase o caso de paciente que teve pioderma gangrenoso após mamoplastia redutora. Respondeu ao corticosteroide sistêmico, e vem evoluindo sem recidivas até o momento.

Pyoderma gangrenosum (PG) is an inflammatory disease of the skin that may develop spontaneously. It is associated with certain systemic and neoplastic diseases, including those of the breasts. PG is also associated with surgical trauma. It has been increasingly reported, along with the increase in the incidence of reduction mammoplasty procedures. The clinical manifestation of ulcers is characteristic of PG and it should be considered in cases of poor healing with intense inflammatory reaction, tissue loss, bloody and/ or purulent secretion, granular background, and lesions with high edges. We describe a patient who developed PG after reduction mammoplasty. She has since responded to systemic corticosteroids and has had no relapse to date.

Aplicación de lipotransferencia en la reconstrucción mamaria por cáncer / Application of lipotransference in breast reconstruction due to cancer

RESUMEN Introducción: El resultado estético de la reconstrucción mamaria depende de varios factores difíciles de evaluar, la aplicación de la lipotransferencia ofrece alternativas para lograr mejores resultados estéticos y mayor satisfacción de las pacientes. Objetivo: Introducir la técnica de lipotransferencia en el instituto nacional de oncología de Cuba Métodos: Se realizó un estudio descriptivo, prospectivo, de corte longitudinal, en 10 pacientes a las que se les practicó técnica de lipotransferencia para reconstrucción mamaria por cáncer, que fueron operadas en el Instituto Nacional de Oncología y Radiobiología (INOR), en el período comprendido entre noviembre de 2016 y noviembre de 2018. Resultados: La técnica fue aplicada con mejores resultados estéticos en pacientes reconstruidas con expansión tisular. Se logró mejorar la disponibilidad de tejidos y amortiguar los daños de la radioterapia. La cantidad de grasa infiltrada fue hasta 400 ml, lo que propició mejorar la calidad de los tejidos y el contorno de la mama reconstruida. Obteniéndose con ello mejor simetría. Conclusiones: La aplicación de esta técnica complementaria, permite obtener mejores resultados estéticos y de esta mejor simetría en pacientes reconstruidas por cáncer de mama(AU)

ABSTRACT Introduction: The aesthetic result of breast reconstruction depends on several factors that are difficult to evaluate. The application of lipotransference offers alternatives to achieve better aesthetic results and greater patient satisfaction. Objective: To introduce the lipotransference technique in the Cuban National Institute of Oncology Methods: A descriptive, prospective, longitudinal-section study was carried out in 10 patients who underwent lipotransfer technique for breast reconstruction due to cancer, who underwent surgery at the National Institute of Oncology and Radiobiology (INOR), in the period between November 2016 and November 2018. Results: The technique was applied with better aesthetic results in reconstructed patients with tissue expansion. Tissue availability was improved and the damage from radiation therapy was cushioned. The amount of fat infiltrated was up to 400 ml, which favored improving the quality of the tissues and the contour of the reconstructed breast. Thus obtaining better symmetry. Conclusions: The application of this complementary technique allows obtaining better aesthetic results and this better symmetry in patients reconstructed for breast cancer(AU)
