[Chondrosarcomatous metaplastic carcinoma of the breast, a rare tumor]. / Carcinoma metaplásico condrosarcomatoide de mama, una entidad inusual.

Metaplastic carcinomas of the breast are uncommon, accounting for less than 0.2% of all breast cancers. Clinically and radiologically, metaplastic carcinomas are indistinguishable from typical ductal carcinomas, and the diagnosis is made histologically by the finding of a mesenchymal component. We present a case of chondrosarcomatous metaplastic breast carcinoma whose definitive diagnosis required immunohistochemical techniques to confirm the malignant epithelial component of the tumor. Accurate diagnosis is important because this tumor behaves differently: it usually spreads through the blood (whereas typical epithelial carcinomas spread through the lymph vessels), metastases present during follow-up rather than before diagnosis, and the five-year survival rate is 35%.

Radiology volunteers to support a breast cancer screening program in Peru: Description of the project, preliminary results, and impressions.

Breast cancer is the second most common cancer in Peruvian women. Due to limitations in national breast cancer screening programs, especially in rural areas, more than 50% of cases of breast cancer in Peru are diagnosed in advanced stages. In collaboration with a local clinic registered as a nongovernmental organization (CerviCusco), RAD-AID International aims to create a sustainable diagnostic structure to improve breast cancer screening in Cuzco. With the support of local, national, and international partners that have collaborated in analyzing radiological resources, raising awareness in the population, acquiring equipment, training clinical staff, and building referral networks, our teams of radiologists, included in the RAD-AID team, have participated in training CerviCusco staff in breast ultrasound, thus enabling additional training for radiology residents through a regulated international collaboration.

El cáncer de mama es el segundo cáncer más frecuente en las mujeres peruanas. Las limitaciones de los programas nacionales de detección precoz, sobre todo en las regiones rurales, propician que más del 50% de los nuevos casos de cáncer de mama en Perú se diagnostiquen en estadios avanzados. RAD-AID Internacional, en colaboración con una clínica local registrada como organización no gubernamental (CerviCusco), pretende crear una estructura diagnóstica sostenible que mejore el cribado del cáncer de mama en Cuzco. Para ello se ha contado con socios locales, nacionales e internacionales que han colaborado en el análisis de recursos radiológicos, la concienciación de la población, la adquisición de equipamiento, el entrenamiento clínico y las redes de referencia. Nuestros equipos de radiólogos, incluidos en el equipo RAD-AID, han participado en la capacitación ecográfica del personal de CerviCusco, permitiendo una formación adicional a los residentes de radiología gracias a una colaboración internacional reglada.(AU)

Carcinoma metaplásico condrosarcomatoide de mama, una entidad inusual / Chondrosarcomatous metaplastic carcinoma of the breast, a rare tumor

El carcinoma metaplásico de mama es una entidad infrecuente (menos del 0,2% de todos los cánceres de mama), que se caracteriza por presentar un componente mixto epitelial y mesenquimal. Este último componente es el que establece su clasificación histológica. Así, su diagnóstico es puramente histológico, pues clínica y radiológicamente no se diferencia de un carcinoma ductal típico. Presentamos un caso de carcinoma metaplásico de mama tipo condrosarcomatoide, cuyo diagnóstico definitivo requirió un estudio mediante técnicas de inmunohistoquímica para confirmar el componente epitelial maligno del tumor. Diagnosticarlo es importante porque su comportamiento es diferente, suelen diseminarse por vía hematógena (el carcinoma epitelial típico lo hace por vía linfática), las metástasis no se presentan en el momento del diagnóstico, sino durante el seguimiento, y su supervivencia a los 5 años es del 35% (AU)

La importancia del conocimiento del estado axilar prequirúrgico en el manejo clínico de la paciente con cáncer de mama / No disponible

La valoración del parámetro N clínico o prequirúrgico puedeser determinante para el correcto manejo de la pacientecon cáncer de mama, siendo la ecografía axilar y la comprobacióncito/histológica de los ganglios sospechosos las técnicasradiológicas de elección en dicha valoración. La revisión, basadaen la evidencia, de la influencia del parámetro cN para laadecuada selección de determinadas técnicas y terapias, permiteidentificar los supuestos clínicos a los que deben ir dirigidosnuestros esfuerzos diagnósticos(AU)

The evaluation of the clinical N or preoperative parametercan be crucial for the correct management of patients withbreast cancer. Axillary ultrasonography and cytohistologicalstudy of suspicious lymph nodes are the radiological techniquesof choice for this evaluation. An evidence-based reviewof the impact of the clinical N parameter on the selection ofthe most appropriate techniques and treatment makes it possibleto identify the clinical targets our diagnostic efforts shouldbe directed at(AU)
