Core needle biopsy in fibroepithelial tumors: predicting factors for phyllodes tumors

OBJECTIVES: This study aimed to evaluate the clinical and imaging predictive factors for the diagnosis of phyllodes tumors in patients with inconclusive results from core needle biopsy (fibroepithelial lesions). METHODS: We retrospectively analyzed data of patients who underwent surgical excision of breast lesions previously diagnosed as fibroepithelial lesions. Numeric variables were analyzed using the Shapiro-Wilk and t-tests, and categorical variables were analyzed using the chi-square and Fisher's exact tests. Multivariate logistic regression was performed to calculate odds ratios and detect predictive factors for the diagnosis of PT. RESULTS: A total of 89 biopsy samples were obtained from 77 patients, of which 43 were confirmed as fibroadenomas, 43 as phyllodes tumors, and 3 as other benign, non-fibroepithelial breast lesions. The mean tumor size was 3.61 cm (range, 0.8-10 cm) for phyllodes tumors and 2.4 cm (range, 0.8-7.9 cm) for fibroadenomas. The predictive factor for phyllodes tumor diagnosis was lesion size >3 cm (p<0.001). CONCLUSION: Our data indicate that fibroepithelial lesions of the breast larger than 3 cm are more likely to be phyllodes tumors.

Tumor Phyllodes: revision de la literatura / Phyllodes tumor: literature review

Resumen El tumor phyllodes de mama es un tumor fibroepitelial raro, pero clínicamente importante, que representa menos del 1% de las neoplasias de mama. Histológicamente, los tumores phyllodes se clasifican en tres; como: benignos, limítrofes o malignos, basándose en una combinación de criterios histológicos y patológicos. Esta clasificación del tumor phyllodes de mama es precisamente relevante en su clínica. Si bien la recurrencia local del tumor phyllodes puede ocurrir en todos los grados, la metástasis se limita principalmente a casos malignos y pocos casos limítrofes, por lo general siendo estos dos últimos los que presentan un peor pronóstico de la enfermedad. El tratamiento es principalmente quirúrgico ya que los tumor phyllodes no responden bien a la terapia sistémica. Esta revisión del tumor phyllodes de mama permite orientar a toda la comunidad médica, con base en la evidencia más reciente, a diagnosticar y así poder manejar esta patología, evitando sus complicaciones.

Abstract Phyllodes tumor of the breast is a rare, but clinically important fibroepithelial tumor, accounting for <1% of breast tumors. Histologically, phyllodes tumor is classified into three; as: benign, borderline or malignant, based on a combination of histological and pathological criteria. This classification of the phyllodes breast tumor is precisely relevant in the clinic. While local recurrence of phyllodes tumor may occur in all grades, metastasis is mostly limited to malignant and few borderline cases, usually the latter two types having a worse prognosis of the disease. Treatment is mainly surgical as phyllodes tumor doesn´t respond well to systemic therapy. This review of the phyllodes tumor allows to guide the entire medical community based on the most recent evidence to diagnose and thus be able to manage this pathology, avoiding its complications.

Caso Clínico: Tumor Phyllodes / Case Report: Tumor Phyllodes

INTRODUCCIÓN: El tumor phyllodes representa menos del 1 % de los tumores mamarios, con una incidencia de 2.1 por millón a nivel mundial, la edad de presentación es entre los 35 a 55 años. Las mujeres latinas tienen mayor riesgo de tumor phyllodes que otros grupos étnicos. En Ecuador las ciudades con mayor incidencia son Quito, Guayaquil y Loja según el Registro Nacional de Tumores; en Cuenca se presenta un caso por año. CASO CLÍNICO: Paciente femenino de 46 años, con antecedente de resección de fibroadenoma en mama derecha 2 años antes, quien hace seis meses atrás, presenta tumor multilobulado de crecimiento rápido, móvil, definido, que ocupa el 80 % de la mama derecha, ecografía BIRADS II; mamografía BIRADS 0. Biopsia con aguja fina presenta resultado histopatológico de tumor phyllodes limítrofe. EVOLUCIÓN: Con el reporte de patología de tumor phyllodes maligno de alto grado con límites negativos, se realizó mastectomía; posteriormente paciente no necesito tratamiento adyuvante, al momento con buen pronóstico. CONCLUSIÓN: El tumor phyllodes maligno es poco frecuente, pero debe considerarse como diagnóstico diferencial en pacientes mayores de 35 años, su tratamiento estandarizado es quirúrgico, sin haberse demostrado que un tratamiento adyuvante pueda disminuir la recurrencia loco regional o a distancia.

BACKGROUND: The phyllodes tumor represents less than 1 % of mammary tumors, with an incidence of 2.1 per million worldwide, the age of presentation is between 35 to 55 years. Latina women are at higher risk of phyllodes tumor than other ethnic groups. In Ecuador, the cities with the highest incidence are Quito, Guayaquil and Loja according to the National Registry of Tumors. In Cuenca, one case is presented per year. CASE REPORT: Female patient of 46-year-old woman with a history of resection of fibroadenoma in the right breast 2 years; who 6 months ago, presented a rapidly growing, mobile, defined multi-lobed tumor that occupies 80 % of the right breast, BIRADS II ultrasound; mammography BIRADS 0. Fine needle biopsy presents histopathological result of phyllodes borderline tumor. EVOLUTION: Mastectomy was performed with high-grade malignant phyllodes tumor pathology report with negative limits, the patient does not need adjuvant treatment, and it remains good prognosis. CONCLUSION: Malignant phyllodes tumor is rare, but it should be considered as a differential diagnosis in patients older than 35 years, it is standardized treatment surgical, without having demonstrated that an adjuvant treatment can reduce loco or regional recurrence.

Tumor phyllodes maligno gigante de mama; neoplasia infrecuente de mal pronóstico: a propósito de un caso clínico / Giant phyllodes tumor of the breast; uncommon neoplasm of poor prognosis: clinical case

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.

Tumores filoides de la mama. Experiencia de 2 años / Phyllodes of breast tumors. 2 years of experience

Introducción: Los tumores filoides constituyen un grupo de raros tumores fibroepiteliales de la mama, representan el 0,3-1,0%. El diagnóstico preoperatorio inadecuado conduce con frecuencia a la escisión local con márgenes positivos, lo cual precisara una cirugía de ampliación de márgenes por la alta probabilidad de recidiva. Objetivo: Describir las características demográficas, diagnóstico, tratamiento y evolución de pacientes portadores de tumores filoides en el período de marzo del 2012 a marzo del 2014 en el Servicio de Mastología del Hospital Central del Instituto de Previsión Social. Pacientes y método: Estudio retrospectivo, observacional, descriptivo de casos consecutivos. Resultados: En 2 años se identificaron 11 casos de tumores filoides, el rango de edades fue de 33-66 años, promedio de 45.9. Las tumoraciones presentaron tamaños entre 4 a 16 cm, promedio de 8.3 cm. Todos fueron sometidos a biopsia con aguja gruesa que informo sospecha de filoides en 8 de 11, en 2 casos informo un fibroadenoma. Todos fueron sometidos a exceresis de la tumoración en donde 2 casos los márgenes estuvieron comprometidos y precisaron ampliación de márgenes, los 2 casos que fueron informados como fibroadenoma. Todas las pacientes presentan un periodo de controles mayores a 6 meses libres de enfermedad. Conclusión: La edad promedio fue de 45.9 años, el diagnóstico se realizó por biopsia con aguja gruesa, donde el informe anatomopatológico reveló tumor filoides en el 72% de los casos, la excéresis tumoral fue el tratamiento, sin complicaciones.

Introduction: These neoplasms are a group of rare fibroepithelial tumors of the breast, accounting for 0.3-1.0% of breast tumors. Phyllodes tumors are generally classified into benign, borderline, and malignant tumors. Inadequate preoperative diagnosis often leads to local excision with positive margins, which will require surgery to expand margins because of the high probability of recurrence. Objective: Describe the demographic characteristics, diagnosis, treatment, and evolution of patients with tumor phyllodes in the period of March 2012 to March of 2014 in the service of Mastology of the Hospital Central of the Institute of Social Welfare. Patients an methods: Retrospective, observational, descriptive study of consecutive cases. Results: In two years 11 cases of phyllodes tumors were identified, the age range was between 33 to 66 years old, mean 45.9. The tumors had sizes gobetween 4-16 cm, mean 8.3 cm. All underwent core needle biopsy that inform suspected phyllodes in 8 of 11 cases, in 2 cases they reported a fibroadenoma. All underwent exeresis of the tumor where 2 cases were committed and required margins expanding margins, both were the reported as fibroadenoma. All patients have a greater control period to 6 months free of disease. Conclusion: Phyllodes tumors are a group of rare fibroepithelial tumors of the breast, accounting for 0.3-1.0% of all breast tumors (5, 6). To distinguish a phyllodes tumor of a fibroadenoma through physical examination is extremely difficult, a core biopsy can accurately diagnose most diseases of the breast (16, 17), but may be inconclusive to differentiate a benign fibroadenoma of a phyllodes tumor.

Phyllodes tumor of the breast: a clinic-pathologic study of 77 cases in a Hispanic cohort / Tumor Phyllodes de la mama: Estudio clínico-patológico de 77 casos en una cohorte hispana

Introduction: Breast Phyllodes tumors are rare breast tumors present in less than 1% of new cases of breast cancer, usually occurring among middle-aged women (40-50 yrs). Objective: This study shows diagnostic experience, surgical management and follows up of patients with this disease during a period of ten years in a oncology referral center. Methods: Retrospectively, breast cancer registries at the institution were reviewed, identifying 77 patients with Phyllodes tumors between 2002 and 2012, who had been operated on at the Instituto de Cancerología - Clínica Las Américas, in Medellín (Colombia). Clinical and histopathological data belonging to these cases was captured and analyzed and descriptive statistics were used. Results: The follow up median was 22.5 months (IQR: 10.5-60.0), average age was 47.2 yrs (SD: 12.4), mean tumor size was 3.6 cm (SD: 4.6), 88.3% of the patients (68 cases) presented negative margins and none of them received adjuvant chemotherapy. Of the patients with Phyllodes tumors; 33.8% had benign, 31.2% had borderline and 35.0% had malignant tumor. Disease-free survival was 85.8% and overall survival was 94.5%. Discussion: Reported data in this article is in accordance with what has been reported in worldwide literature. In our cohort even the high mean size of the tumors, the risk of local relapse and metastatic disease is low than previously reported in literature. Trials with longer follow up and molecular trials in Phyllodes tumors are necessary to understand the behavior of these tumors in Hispanics population.

Introducción: Los tumores phyllodes mamarios son Tumores infrecuentes en la mama presentes en menos del 1% de los casos nuevos de cáncer mamario, por lo general ocurre en mujeres de mediana edad (40-50 años) Objetivo: Este estudio muestra la experiencia de diagnóstico, tratamiento quirúrgico y seguimiento de los pacientes con esta variedad de tumor durante un período de diez años en un centro de referencia oncológico. Métodos: Retrospectivamente, los registros de cáncer de mama en la institución fueron revisados, se identificaron 77 pacientes con tumores phyllodes entre 2002 y 2012, que habían sido operados en el Instituto de Cancerología - Clínica Las Américas, en Medellín (Colombia). Los datos clínicos e histopatológicos pertenecientes a estos casos fueron recolectados y analizados utilizando técnicas de estadística descriptivas. Resultados: La mediana de seguimiento fue de 22.5 meses (RIC: 10.5-60.0), la Media de edad fue de 47.2 años (DE: 12.4), tamaño medio del tumor fue de 3.6 cm (DE: 4.6), 88.3% de los pacientes (68 casos) presentaron márgenes negativos y ninguno de ellos recibieron quimioterapia adyuvante. De los pacientes con tumores phyllodes; 33.8% fueron benignos, 31.2% Borderline y 35.0% phyllodes maligno. Supervivencia libre de enfermedad fue 85.8% y la supervivencia global fue de 94.5%. Discusión: Los datos reportados en este artículo están acordes con lo que se ha reportado en la literatura mundial. En nuestra cohorte, a pesar de que el tamaño promedio de los tumores fue mayor, el riesgo de recidiva local y las tasas de enfermedad metastásica es menor que el reportado previamente en la literatura. Los ensayos con seguimiento más prolongado, y los ensayos moleculares en tumores phyllodes son necesarios para comprender de una manera mas precisa el comportamiento de estos tumores en la población hispana.

Comparison of stromal CD10 expression in benign, borderline, and malignant phyllodes tumors among Egyptian female patients.

Background: Phyllodes tumors are group of biphasic fibroepithelial tumors of the breast of varying malignant potential, ranging from benign tumors to fully malignant sarcomas. According to the Egyptian National Cancer Institute, female malignant cases showed appreciable increase in the recent time period for breast cancer with the malignant phyllodes tumors representing 0.41% of cases in the year 2003-2004. Aims: This is an immunohistochemical study to compare CD10 expression in benign, borderline, and malignant phyllodes tumors, in order to highlight its diagnostic and prognostic values. Materials and Methods: This study conducted 34 Egyptian female cases of phyllodes tumors of different grades to be studied histologically and immunohistochemically using antibodies against CD10. Statistical Analysis: The Chi-square test was used to determine differences in CD10 expression between benign, borderline, and malignant tumors. One-way ANOVA test was used to determine whether the difference was significant. Significance was established at P<0.05. Results: In the 24 cases of benign phyllodes tumors, only four cases (16.7%) showed positive CD10 reactivity. Three cases (60%) out of five borderline phyllodes tumors showed positive CD10 reactivity, while four (80%) out of five cases of malignant phyllodes tumors showed positive CD10 staining. Conclusion: From these highly significant results, we believe that there is a strong correlation between CD10 expression and tumor grade, which could be an important observation that may have both diagnostic and prognostic implications as well as promising potential target for development of novel therapies.

Tumores phyllodes de mama: clínica, tratamiento y pronóstico: Hospital Universitario de Canarias, España / Phyllodes tumor of the breast

El tumor Phyllodes de mama es un tumor poco frecuente que se engloba dentro de los tumores fibroepiteliales de mama, con un amplio abanico de presentación clínica y comportamiento biológico. Se clasifican en benignos, borderline o malignos, en base a factores histológicos. Las formas menos agresivas o benignas presentan un comportamiento similar al de los fibroadenomas, sin embargo las formas malignas suelen presentar un comportamiento más agresivo. El pronóstico de este tipo de tumor es favorable, con una recurrencia local del 15 por ciento de forma global y recurrencia a distancia entre 5-10 por ciento. El tratamiento se basa en la escisión quirúrgica de la lesión, acompañada de radioterapia e incluso quimioterapia en las formas más agresivas. Presentamos la revisión de 13 casos clínicos de esta entidad diagnosticados en nuestro centro entre 2001-2009.

Phyllodes tumor of the breast is a rare tumor, which is part of fibroepithelial breast tumors with a wide range of clinical presentation and biological behavior. They are classified into benign, borderline or malignant based on histologic factors. The less aggressive or benign forms show a more behavior to that of fibroade-nomas, but malignant forms usually show a more aggressive behavior. The prognosis of this tumor is favorable, with local recurrence in 15 percent overall and distant recurrence between 5-10 percent globally. The treatment relies on surgical excision of the lesion accompanied by radiotherapy and chemotherapy even in the most aggressive. We present a review of 13 cases of this entity diagnosed in our center between 2001-2009.

Malignant phyllodes tumor of the breast metastasizing to the peritoneal cavity

A fifty-three year old Bahraini female presented with painless rapidly growing mass in the right breast of 3 months duration; no nipple discharge was found. Family history was positive for breast carcinoma in situ in her sister. Lumpectomy was performed. Histopathology proved to be phyllodes tumor; therefore, mastectomy was performed to avoid local recurrence. The patient received local radiation to the mastectomy scar. Four months after the initial surgery, she developed a nodule in the mastectomy scar, left breast lump in the upper outer quadrant and intra-abdominal mass. A fine needle aspiration of the mass in the left breast showed spindle cells with focal atypia and a necrotic background. True-cut biopsy of the intra-abdominal mass showed the metastatic stromal component of the malignant phyllodes tumor with malignant spindle cells. The patient condition worsened, developed bilateral pleural effusions. Adriamycin chemotherapy was planned, but the disease was aggressive enough to end her life within weeks

Tumor phyllodes en una niña de 11 años. Comunicación de un caso / Phyllodes tumor in an 11 years-old girl. Report of a case

El objetivo es presentar el caso de una niñade 11 años de edad con un tumor phyllodes de mama derecha.Al efectuar una revisión bibliográfica, hallamos sólo dos casos publicados.

Tumor filoides de la mama / Phyllodes tumor of the breast

Introduction: The phyllodes tumor (PT) of the breast is a rare disease of unknown origin. Despite its classification into benign, borderline and malignant, their behavior tends to be uncertain. Because of this, treatment remains controversial. Objective: To describe the management of the FT in breast pathology unit of our hospital and their outcomes. Material and Methods: We retrospectively reviewed the files of the patients with PT, operated in our hospital between 2001 and 2008. We analyzed the clinical characteristics, diagnostic studies, treatment and outcomes. Results: During this period 12 patients were operated. The ave-rage age was 42 +/- 15.2 years (16-64) and usually the form of presentation was painless palpable nodule. Both mammography and ultrasound were unable to suggest the diagnosis. Eight patients had core biopsy, which revealed the diagnosis of PT in 5, while in the other 3 was fibroadenoma. All patients underwent a partial mastectomy. The biopsy showed six benign, two borderline and two malignant PT. The latter two patients received adjuvant radiotherapy. At the end of this study, 2 patients had relapsed at 12 and 30 months (borderline and benign, respectively). There were no cases of lymphatic or distant metastases. Conclusions: The PT has a low frequency of presentation and preoperative diagnosis is difficult, so we recommend a core biopsy, but it can confuse with fibroadenoma. The management with partial mastectomy and negative borders had a recurrence rate of 18 percent in this series.

Introducción: El tumor filoides (TF) de la mama es una patología poco frecuente y origen desconocido. A pesar de su clasificación en benignos, borderline y malignos, su comportamiento tiende a ser incierto. Debido a esto su tratamiento sigue siendo controversial. Objetivo: Describir el manejo del TF en la unidad de patología mamaria del Hospital San José y sus resultados. Material y Método: Se revisaron las fichas de las pacientes con diagnóstico de TF, operadas en nuestro hospital entre los años 2001 y 2009. Se analizaron las características clínicas, estudios diagnósticos, tratamiento y resultados. Resultados: Durante este período se operaron 12 pacientes. El promedio de edad fue 42 +/- 15,2 años (16-64) y habitualmente la forma de presentación fue nodulo palpable indoloro. Tanto la mamografía como la ecografía fueron incapaces de sugerir el diagnóstico. Ocho pacientes tenían biopsia core, la cual evidenció el diagnóstico de TF en 5, mientras que en las otras 3 resultó fibroadenoma. Todas las pacientes fueron sometidas a mastectomía parcial. En seis pacientes resultó ser TF benigno, en dos borderline y en dos maligno. Estas últimas dos pacientes recibieron radioterapia adyuvante. Al término de este estudio 2 pacientes habían recidivado a los 12 y 30 meses (borderline y benigno respectivamente). No hubo casos de metástasis linfáticas ni a distancia. Conclusiones: El TF tiene una baja frecuencia de presentación, su diagnóstico preoperatorio es difícil recomendándose la biopsia core, sin embargo, suele confundirse con el fibroadenoma. El manejo con mastectomía parcial y bordes negativos tuvo una recidiva del 18 por ciento en esta serie.

Patología mamaria benigna / Benignant pathology of the breast

The benignant pathology of the breast involves a group of several pathologies, from simple congenital malformations through complex disorders, development anomalies, injureis, both chronic and acute infections, non infectious inflammatory processes, benignant tumors and functional disorders such as mammary dysplasia. The authors of this report describe successivelvy the characteristics of mammary anomalies, inflammatory processes (mastitis) benignant tumors of the breast (fibroadenoma), tumor phyllodes, papillary tumors, mammary dysplasias. In every case the diagnosis, with radiologic imaging and nuclear imaging, with other diagnostic techniques, follow-up and surgical approach, are described and detailed.

Phyllodes Tumour in Young Female Adults in Port Harcourt; Nigeria

Background: Phyllodes tumour of the breast is a rare and potentially aggressive tumour. Little information is available regarding the optimal management of this tumour and rarer still; are data regarding survival. We report our experience in the diagnosis; management and outcome of phyllodes tumour. Patients and Methods: The hospital case notes of adolescent female patients found to have phyllodes tumour from 1997 to 2007 were identified from the medical records department of the hospital. Data extracted included sex; age; presenting symptoms; anatomical site of lesion and clinical evaluation including approximate size of the breast masses. Results of investigations including haemogram; urea and electrolytes; chest xray; ultrasonography; tru-cut and excision biopsy; surgical treatment and outcome of treatment were obtained. The follow up visits to the outpatient clinic were also noted. Results: There were 17 females aged between 25 and 30 years. Five patients had previous excision biopsy of fibrodenoma from the ipsilateral breasts when they were teenagers. The median tumour size was 17.5 cm in diameter. There were no clinical features suggestive of malignancy. The chest radiographs were within normal limits. Histopathological findings showed that ten (58.82) patients had the benign variety while seven (41.18) had the borderline variety. All had a wide excision of the tumour but were not offered any adjuvant therapy. Conclusion: Early diagnosis and treatment with adequate surgical margins are essential in the successful management of phyllodes tumour
