RESUMO

Radiation-induced breast angiosarcoma is a severe but rare late complication in the breast-preserving management of breast cancer through surgery and radiotherapy [1]. Often the initial diagnosis of this entity is complex given its relatively anodyne nature and usually being present in the form of typically multifocal reddish-purple papular skin lesions [2]. Because of the low incidence of this tumour, there is a limited number of studies regarding its optimal therapeutic management [3]. The preferred treatment is aggressive surgical removal and the prognosis is poor with an overall survival rate of 12-20% at five years [4].

RESUMO

Primary neuroendocrine tumour of the breast is a rare entity that first appeared in the 2003 World Health Organisation (WHO) classification of breast tumours. The data currently available on its prognosis are contradictory, although it seems clear that histological varieties such as small cell neuroendocrine carcinoma have a worse prognosis, due to their low degree of differentiation. The treatment of choice is surgery, and the indications for chemotherapy or radiotherapy do not differ greatly from those used for other breast tumours. It is crucial to underline the difficulty of establishing treatment protocols due to the low incidence of this histological type.

RESUMO

Resumen ANTECEDENTES: El cáncer de mama es la principal neoplasia diagnosticada durante el embarazo y posparto. La incidencia durante el embarazo varía de 0.2-2.6%. El tratamiento implica un reto para los sistemas de salud porque debe valorarse y salvaguardarse el bienestar de la madre y su hijo. CASO CLÍNICO: Paciente de 26 años, que acudió a consulta por mastalgia derecha, con crecimiento rápido a partir del inicio del embarazo. Durante la exploración mamaria se evidenció una tumoración de consistencia dura, de 8 cm, que ocupaba ambos cuadrantes superiores de la mama derecha, con enrojecimiento de la piel. La ecografía reportó una tumoración sólido-quística heterogénea, de 8 x 5 cm, sin ganglios patológicos axilares. El estudio anatomopatológico de la biopsia reportó un carcinoma infiltrante, con inmunofenotipo triple negativo (inmunorreactividad negativa para receptores de estrógenos y progesterona, y Her-2 con índice de proliferación Ki67 de 80%), con lo que se confirmó el diagnóstico de cáncer de mama localmente avanzado en el segundo trimestre del embarazo. Después de la administración de tres ciclos de quimioterapia neoadyuvante con antraciclinas (doxorrubicina y ciclofosfamida) cada tres semanas, se indicó la finalización del embarazo mediante la inducción del parto en la semana 36 + 6. Nació un varón de 2800 g, con Apgar 9-10-10. La madre y su hijo evolucionaron satisfactoriamente, por lo que recibieron el alta hospitalaria 4 días posteriores a la intervención. A 10 meses de la mastectomía la paciente goza de buena salud física y psicológica, al igual que su hijo de 15 meses, y continúa en seguimiento estrecho en el servicio de Oncología. CONCLUSIÓN: El tratamiento del cáncer de mama durante el embarazo es seguro y ofrece buenos resultados a largo plazo. Es importante la intervención y valoración multidisciplinaria, además de la asesoría correcta y el apoyo psicológico a la familia.


Abstract BACKGROUND: Breast cancer is the most prevalent cancer nowadays and is the most common at the pregnancy and postpartum period. The incidence is between 0.2-2.6% and is currently increasing due to delayed childbearing. The treatment implies a challenge for the health systems because the welfare of the mother and her child must be valued and safeguarded. CLINICAL CASE: A 26-year-old patient who attended the consultation for right mastalgia, with rapid growth from the beginning of pregnancy. During the mammary examination, a hard consistency tumor of 8 cm was observed, occupying both upper quadrants of the right breast, with reddening of the skin. The ultrasound revealed a heterogeneous solid-cystic tumor, 8 x 5 cm, without pathological axillary lymph nodes. The anatomopathological study of the biopsy reported an infiltrating carcinoma, with triple negative immunophenotype (negative immunoreactivity for estrogen and progesterone receptors, and Her-2 with Ki67 proliferation index of 80%), which confirmed the diagnosis of breast cancer locally advanced in the second trimester of pregnancy. After administration of three cycles of neoadjuvant chemotherapy with anthracyclines (doxorubicin and cyclophosphamide) trisemanales, termination of pregnancy was indicated by induction of labor at week 36 + 6. A male was born at 2800 g, with Apgar 9-10- 10 The mother and her son evolved satisfactorily, so they were discharged 4 days after the intervention. Ten months after mastectomy, she enjoys good physical and psycho-logical health, as does her 15-month-old son. Continues in close monitoring in the Oncology service. CONCLUSIONS: The treatment of breast cancer during pregnancy is safe and offers good long-term results. The important intervention and multidisciplinary assessment, in addition to the correct advice and psychological support to the family.

RESUMO

RESUMEN El cáncer de mama es el tumor más prevalente a nivel mundial entre las mujeres. A pesar de que la supervivencia global alcanza cifras cercanas al 90%, sigue suponiendo un importante problema sanitario y económico para la población. Los sarcomas primarios de mama suponen menos del 1% de estas neoplasias, pero sus tasas de recidiva y mortalidad son elevadas. Dado que no existen pruebas de imagen específicas para el diagnóstico, la confirmación de dicha entidad supone un reto a nivel histopatológico. El tratamiento del osteosarcoma de mama es principalmente quirúrgico, con la extirpación de la tumoración con márgenes adecuados, que será trascendental para el pronóstico de las pacientes. No se ha demostrado que sea necesaria una disección axilar, ni un tratamiento adyuvante estándar de quimioterapia ni radioterapia, salvo casos indicados. Presentamos el caso de una paciente postmenopaúsica que tras haber desarrollado un carcinoma ductal in situ de mama tratado de forma satisfactoria, desarrolla dos años posterior a la finalización del tratamiento radioterápico, y en la misma localización del tumor inicial, un osteosarcoma primario de mama de rápido crecimiento atribuible al efecto de la radioterapia administrada.


ABSTRACT Breast cancer is the most prevalent tumor worldwide among women. Despite the fact that overall survival reaches figures close to 90%, it continues to be an important health and economic problem for the population. Primary breast sarcomas account for less than 1% of these neoplasms but their rates of recurrence and mortality are high. Given that there are no specific imaging tests for diagnosis, confirmation of this entity is a challenge at the histopathological level. The treatment of the OSM is mainly surgical with the removal of the tumor with adequate margins, which will be transcendental for the prognosis of the patients. It has not been demonstrated that an axillary dissection is required, nor a standard adjuvant treatment of chemotherapy or radiotherapy, unless indicated. We present the case of a postmenopausal patient who, after having developed a ductal carcinoma in situ of the breast (DCIS) successfully treated, developed two years after the end of the radiotherapy treatment, and in the same location of the initial tumor, an osteosarcoma primary breast of rapid growth attributable to the effect of radiotherapy administered.

RESUMO

Los tumores Phyllodes agrupan un conjunto de patologías caracterizadas por presentar una arquitectura histológica estromal y epitelial; dividiéndose en benignos, borderline o malignos, en función de múltiples características. Se desarrollan más frecuentemente en pacientes entre los 35-55 años de edad, representando el 0.3%-1% de los tumores primarios de la mama. Clínicamente se caracterizan por la aparición de una masa indolora, firme, dura, multilobulada y de crecimiento rápido que puede llegar a alcanzar un gran tamaño, denominándose gigantes cuando superan los 10 cm de longitud. El diagnóstico de los tumores Phyllodes, se basa en el estudio anatomopatológico mediante biopsia radioguiada y las pruebas de imagen mamarias. La cirugía conservadora o radical, con márgenes de resección quirúrgica libres de enfermedad mayores de 1 cm, y la radioterapia adyuvante sobre el lecho tumoral, son el tratamiento de elección de este tipo de tumores. El tamaño de la masa, el tipo histológico y la afectación tumoral de los bordes quirúrgicos son los principales factores de riesgo de recurrencia, que puede alcanzar un 40%, siendo casi siempre a nivel local. Por otro lado, la probabilidad de desarrollar metástasis a distancia presenta una mayor variabilidad, siendo más frecuente a nivel pulmonar y óseo. A continuación, presentamos el caso de una paciente diagnósticada de un tumor Phyllodes maligno gigante de mama derecha (mayor de 20 cm) que, tras tratamiento mediante cirugía radical y radioterapia adyuvante, desarrolló múltiples metástasis a distancia, recibiendo actualmente cuidados paliativos, a pesar de los esfuerzos terapéuticos multidisciplinares realizados.


Those Phyllodes tumors grouped a set of pathologies characterized by presenting an architecture histological stromal and epithelial; divided into benign, borderline or malignant, based on multiple characteristics. Occur most frequently in patients between 35-55 years of age, representing 0.3% - 1% of primary tumors of the breast. Clinically is characterized by the appearance of a mass painless, firm, hard, multilobulated and of growth fast that can get to reach a great size, calling is giant when exceed the 10 cm of length. Phyllodes tumors diagnosis, based on the study pathological radioguided biopsy and breast imaging tests. It surgery conservative or radical, with margins of resection surgical free of disease greater of 1 cm, and the radiation therapy adjuvant on the bedding tumor, are the treatment of choice of this type of tumors. He size of the mass, the type histologically and it involvement tumor of them edges surgical are the main factors of risk of recurrence, that can reach a 40%, being almost always to level local. On the other hand, the probability of developing metastasis to distance presents a greater variability, being more frequent to level lung and bone. Then, present the case of a patient diagnosed of a tumor Phyllodes malignant giant of mama right (greater of 20 cm) that, after treatment by surgery radical and radiotherapy adjuvant, developed multiple metastasis to distance, receiving currently care palliative, despite those efforts therapeutic multidisciplinary made.
