ABSTRACT

We report a rare case of dedifferentiated liposarcoma in a man. A 60-year-old male patient presented with a left mass involving the whole breast area, with no lymph node enlargement, growing during a one-year-period. Imaging studies revealed a fat-containing mixed-density mass apparently associated with the pectoralis major muscle. A core biopsy was performed that yielded a diagnosis of a well-differentiated liposarcoma. Further tests to check for metastases were ordered and no distant disease was found. Left mastectomy with en bloc resection of the pectoralis major muscle was performed. The pathologic diagnosis revealed a high-grade dedifferentiated liposarcoma with extensive necrosis. This tumor type is primarily described in the retroperitoneum and extremities. We report an unusual presentation of a liposarcoma mimicking a breast mass.

ABSTRACT

Introducción: las pacientes con cáncer de mama con receptores hormonales positivos mantienen una tasa de recurrencia significativa durante el seguimiento prolongado. La predicción del patrón de recurrencia puede ayudar en el desarrollo de estrategias específicas de vigilancia y tratamiento en pacientes con cáncer de mama. Material y método: estudio analítico observacional, de cohorte retrospectivo en el cual se analizaron los datos de 203 pacientes del Hospital J. M. Penna en el periodo comprendido entre enero de 2005 y enero 2015. Objetivo: el objetivo principal de este trabajo es evaluar la asociación que existe entre los receptores de progesterona (RP) negativos (0%) con probabilidad de recaída local y a distancia luego del tratamiento del cáncer de mama. Resultados: las pacientes con RP negativo mostraron mayor edad que las pacientes con RP positivo (61,24+/-12,4 años vs 57+/-13.7; p=0,0480), menor porcentaje de pacientes premopáusicas (17,54% vs 35,62%; p=0,012); y también una mayor tendencia de compromiso ganglionar axilar (36,9% vs 26,,5%; p=0,098). En el análisis multivariado no se observó que el estatus negativo en los RP sea un factor de riesgo independiente para recidiva local (OR=1,28; IC95%=0,44-3,68), recidiva en forma independiente menor SLE (OR=1,18, IC95%0,52-2,64). Conclusiones: en esta población no se logró demostrar asociación significativa independiente de otros factores entre el estatus negativo de los RP y la supervivencia libre de enfermedad en las pacientes operadas de cáncer de mama. El análisis de los resultados nos demuestra la necesidad de realizar nuevos estudios, con un mayor número de pacientes y mayor tiempo de seguimiento, para dilucidar el real papel del RP


Introduction: patients with breast cancer with positive hormone receptors maintain a significant recurrence rate during prolonged follow-up. Predicting the pattern of recurrence can aid in the development of specific surveillance and treatment strategies in patients with breast cancer. Material and method: observational, retrospective cohort analytic study that analyzed the data of 2003 patients of Hospital José María Penna between january 2005 and january 2015. Objetive: the main objetive of this stydy is to evaluate the correlation that exists between negative (0%) progesterone receptors (PR) and the likelihood of local and distant relapse after treatment of breast cancer. Results: patients with negative PR showed greater age than patients with positive PR (61.24+/-12.4 years old vs 57+/-13.7; p=0,048), lower percentage of postmenopausal patients (17.54% vs 35.62&; p=0.012), and also a greater tendency of axillary lymph node involvement (36.9% vs 26.5%; p=0.098). In the multivariate analysis it was not observed that the negative status in the PR is an independent risk factor for local recurrence (OR 1.28; CI95% 0.44 - 3.68), distant recurrence (OR 1.33; CI95% 0.55 - 3.21), or a factor that conditions independently lower DFS (OR 1.18; CI95% 0.52 - 2.64). Conclusions: in this population it was not possible to demonstrate significant correlation independent of other factors between the negative status of PR and the disease-free survival in patients who underwent surgery for breast cancer. The analysis of the results shows the need to carry out new studies, with a larger number of patients and longer follow-up time, to understand the real role PR plays.

ABSTRACT

El estado axilar es un factor pronóstico para los estadios tempranos de cáncer de mama. Existen factores que podrían predecir riesgo de mayor enfermedad axilar. El objetivo es determinar cuáles son los factores predictivos independientes de alta carga residual ganglionar axilar (4 o más GNC comprometidos) luego de la BGC positiva. Estudio analítico, observacional, cohorte retrospectiva de pacientes con tumores T1-2, axila clínicamente negativa, a las que se les realizó cirugía conservadora (CC) y BGC con resultado positivo (marco o micrometástasis) y se les realizó posterior linfadenectomía axilar (LA). Del total de 325 pacientes, 96 tuvieron resultado positivo para metástasis en el ganglio centinela (29,5%) y también se les realizó LA. Se dividió a la población seleccionada en dos grupos según el compromiso de los GNC: baja carga axilar 0-3 GNC positivos, y alta carga axilar 4 o más GNC positivos. Se observaron como factores que demostraron mayor riesgo para alta carga axilar ganglionar residual al grado histológico, ki-67 y la invasión extracapsular en el GC; pero solamente la invasión extracapsular en el GC demostró ser significativa en el análisis multivariado. Probablemente con un mayor número de pacientes otras variables pudieran haber resultado factores de riesgo independiente


Axillary status is a prognostic factor for early stages of breast cáncer. There are predictive factors that might indicate the risk of greater axilary disease. The aim is to determine which are the independent predictive factor sor a high residual axillary nodal burden (four or more non-sentinel lymph nodes involved) after a positive sentinel node biopsy. Retrospective cohort analytic observational study of patients with T1-2 tumors, negative axilla, who underwent breast conserving surgery and sentinel node biopsy with a positive result (macro ­ or micro-metastasis) and later underwent lymph node dissection. Out of the total 325 patients, 96 got a positive result for metástasis in the sentinel lymph node (29.5%) and also underwent lymph node dissection. The selected population was divided into two groups according to the involvement of NSLNs: low axillary burden: 0-3 NSLNs, and high axillary burden: 4 or more positive NSLNs. Among the factors found to have a higher risk of high residual axillary nodal burden were the histologic grade, Ki-67 and the extracapsular invasión of the SLN, but only the extracapsular invasión of the SLN was found to be significant in the multivariate analysis. It is likely that with a higher number of patients, other variables might have been independent risk factors

ABSTRACT

Introducción La gigantomastia gravídica es una entidad poco frecuente, de etiología desconocida, con una incidencia de 1 en 100.000 embarazos. Se caracteriza por un crecimiento mamario excesivo e invalidante durante la gestación. El tratamiento durante el embarazo es sintomático, requiriendo resolución quirúrgica en el puerperio. Material y método Reporte de caso clínico de gigantomastia gravídica en el Hospital José María Penna de la Ciudad Autónoma de Buenos de Aires en 2017. Caso clínico Paciente de 22 años, primigesta que, cursando embarazo de 20 semanas, consulta por aumento exagerado del volumen mamario, de dos meses de evolución. Se realiza punción percutánea con aguja gruesa cuyo resultado informa parénquima mamario con ductos y lobulillos preservados. Se instaura tratamiento sintomático, decidiéndose la finalización del embarazo durante la semana 34 de gestación por gran disconfort materno asociado a disnea. Durante el puerperio, se inhibe la lactancia, y evoluciona favorablemente con involución mamaria parcial; actualmente se encuentra en plan quirúrgico. Conclusiones La gigantomastia gravídica es de presentación excepcional. El tratamiento es sintomático durante la gestación siendo la resolución quirúrgica fundamental en el puerperio. El manejo multidisciplinario es indispensable.


Introduction Gestational gigantomastia is an unusual condition of unknown origin, which occurs in approximately 1 out of every 100.000 pregnancies. It is defined as an excessive and invalidating mammary hypertrophy which develops during pregnancy. Supportive care for symptomatic relief is offered during pregnancy, but surgical approach and reduction mammoplasty is usually warranted after childbirth. Materials and method The following is a case report of a patient with gestational gigantomastia who was treated at the Hospital Jose Maria Penna de Buenos Aires in 2017. Clinical vignette This is the clinical case of a 22-year-old primigravida, who presented at 20 weeks of pregnancy. She complained of exaggerated bilateral increase in breast volume over the previous two months. Core needle biopsy informed presence of normal breast parenchyma with normal ducts and lobes. Supportive treatment was initiated for symptom relief. Elective termination of pregnancy at 34 weeks was decided because of great materna discomfort and dyspnea. After childbirth, lactation was suppressed and the patient is currently awaiting surgical correction. Conclusions Gestational gigantomastia is an exceptionally rare condition. The therapeutic goal during pregnancy is usually symptom relief. Surgical correction is essential after childbirth and interdisciplinary management is mandatory.
