Cáncer de mama en hombres: revisión de casos en el Hospital Regional de Talca / Breast cancer in men: review of cases at "Hospital Regional de Talca"

Breast cancer in men is a rare pathology. The most common clinical presentation is a palpable and painless retroareolar nodule. In men, it is a rare pathology, there are few studies on the matter, where breast cancer trials frequently exclude men. Objective: to present the incidence of breast cancer in men from the "Regional Hospital of Talca" Method: Retrospective and descriptive study of cases of breast cancer in men who have been treated and followed up in the Breast Pathology Unit of the Regional Hospital of Talca from January 1, 2011 to December 31, 2021.Results: There were 9 cases of breast cancer in men. Average age at diagnosis was 63 years, all patients were 50 years of age or older. One hundred percent of patients consulted for a self-palpable breast nodule. Average size on physical examination was 30 mm. The most frequent histology was invasive ductal carcinoma (56%), followed by invasive tubular carcinoma (22%) and ductal carcinoma in situ (11%). Immunohistochemistry was 100% positive for estrogen and progesterone receptor. Surgery in 56% of cases was total mastectomy with axillary dissection, and in 33% it was total mastectomy alone. 4 patients underwent adjuvant treatment with chemotherapy, and just one required a combination of chemotherapy and radiotherapy. During follow-up, only 2 patients died. Conclusion. Breast cancer in men is not very prevalent and the management is extrapolated from large studies in women, we believe that it is essential to have studies in male patients, to really have clarity on the behavior and evolution of the disease.

Hemogram index parameters in the evaluation of male breast cancer and inflammatory response: a case-control study

SUMMARY OBJECTIVE: Our aim was to investigate the hemogram index parameters and their clinical significance in the evaluation of the inflammatory response of patients with male breast cancer, who are rarely observed in the literature. METHODS: In total, 22 (n=22) healthy male and 28 (n=28) male breast cancer patients without synchronous/metachronous tumors were included in this study. They were grouped as the healthy male control group (Group 1) and the male breast cancer patient group (Group 2). The male breast cancer was divided into two subgroups, namely, early stage [(stage: 0/I/II) (Group 2A)] and late stage [(stage: III/IV) (Group 2B)], and their hemogram index parameters were compared. RESULTS: A significant (p>0.05) increase was observed in neutrophil/lymphocyte ratio (NLR) and·platelet/lymphocyte ratio (PLR) values in the late stage (Group 2B: stage III/IV) compared to the early stage (Group 2A: stage 0/I/II) and healthy control (Group 1) groups. CONCLUSIONS: In male breast cancer patients, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio values were significantly higher as the stage of cancer increased. These readily available simple tests can be used to evaluate the host's inflammatory response in male breast cancer.

Carcinoma epidermoide primitivo de mama en hombre. Presentación de un caso / Primitive Epidermoid Breast Carcinoma in Men. Case Presentation

RESUMEN El carcinoma epidermoide primitivo está considerado el tumor más raro de la mama, con una incidencia que representa solo del 0,04 al 0,075 % de todos los tumores malignos de esta localización. Es una variedad de carcinoma metaplásico constituido por células pavimentosas queratinizantes. Se presenta el caso de un paciente de sexo masculino, de 65 años, de color de piel blanca, residente en el municipio Abreus, provincia Cienfuegos, que acudió a la consulta de mastología de la provincia por presentar una tumoración de 5 cms. en el cuadrante superior externo de la mama derecha, de dos meses de evolución. Se realizó exéresis de la tumoración y se recibió informe de la biopsia con el resultado de carcinoma epidermoide poco diferenciado. Actualmente el paciente se sigue en consulta y está libre de metástasis. Por lo inusual del caso se decide su publicación. Se presenta este reporte por ser el primer paciente de sexo masculino, operado de carcinoma epidermoide de mama en la provincia Cienfuegos.

ABSTRACT Primitive epidermoid carcinoma is considered the rarest breast tumor, with an incidence that represents only 0.04 to 0.05 % of all malignant tumors of this location. It is a variety of metaplastic carcinoma made up of keratinizing pavement cells. The case presented is a 65-year-old white male patient, resident in the Abreus municipality, Cienfuegos province who attended the province's mastology clinic for presenting a 5 cm tumor in the upper external quadrant of the right breast, two months in evolution. Exeresis of the tumor was performed and a report of the biopsy was received with the result of poorly differentiated squamous cell carcinoma. Currently the patient is followed in consultation and is free of metastases. Due to the unusual nature of the case, its publication is decided. This report is presented as the first male patient to undergo surgery for squamous cell carcinoma of the breast in the Cienfuegos province.

Sarcoma neurogénico de la mama masculina. Presentación de un caso / Male breast neurogenic sarcoma. A case

RESUMEN El cáncer de mama en el sexo masculino es una entidad clínica poco frecuente, tiene una presentación unimodal a los 71 años de edad, generalmente se presenta de manera similar a la forma en que se presenta en el sexo femenino. Su causa es poco conocida. Los sarcomas son tumores de componentes mesenquimatoso que constituyen del 0,2-1 % de todos los tumores de mama, y menos del 5 % del total. El sarcoma neurogénico, a su vez, es un tumor extremadamente raro. Representa del 1-2 % aproximadamente, de los tumores de los nervios periféricos con transformación maligna. Debido a la rareza geográfica e histopatológica de este tipo y mucho más en pacientes masculinos se presentó este caso. Paciente masculino de 57 años de edad, con el diagnóstico de un sarcoma de la mama derecha. Se le realizó una mastectomía radical más quimioterapia y radioterapia adyuvante. Los estudios de inmunohistoquímicos permitieron llegar al diagnóstico de sarcoma neurogénico.

ABSTRACT Breast cancer in men (BCM) is a rare clinical entity that has a unimodal presentation at the age of 71 years, and generally presents in a similar way it presents in the female sex. Its etiology remains almost unknown. Sarcomas are tumors of mesenchymal components representing from 0.2 to 1 % of all the breast tumors and less than 5 % of the total. The neurogenic sarcoma is also an extremely rare tumor. It represents around 1-2 % of the peripheral nerves tumors with malignant transformations. Due to location and histopathological rarity of this kind of tumors, much more in male patients, the authors presented the case of a male patient, aged 57 years, with the diagnosis of a left breast sarcoma. He undergone a radical mastectomy plus adjuvant chemotherapy and radiotherapy. The immunohystochemical studies allowed arriving to the diagnosis of neurogenic sarcoma.

Características del cáncer de mama masculino en una población uruguaya / Characteristics of male breast cancer in a Uruguayan population / Características do câncer de mama masculino em uma população uruguaia

El cáncer de mama (CM) en el hombre (CMM) es una entidad poco frecuente. Si bien tiene algunas semejanzas con el CM femenino, es una patología con un perfil propio. El objetivo del estudio consiste en conocer las características del CMM y su manejo en nuestro medio. Materiales y métodos: estudio retrospectivo que incluyó pacientes diagnosticados de CMM en tres centros del Uruguay en un período de 15 años. Resultados: se incluyeron 12 pacientes; la mediana de edad fue 68 años; un tercio de ellos tenían antecedentes familiares (AF). Características clínico patológicas: todos los tumores fueron carcinomas ductales con grado histológico (GH) 2-3, » se hallaban en estadio (E) I, la mitad (6) en EII, 6 tuvieron metástasis axilares, 2/3 fueron receptores de estrógeno (RE) / receptores de progesterona (RP) +. Se definieron 3 subtipos biológicos: I) HER2- RE/RP+: 2/3 de los pacientes; II) HER2+: 1/6; y III) triple negativo: 1/6. Todos los pacientes con enfermedad localizada fueron sometidos a mastectomía y la mayoría recibió tratamiento con quimioterapia (QT). La totalidad de quienes presentaron enfermedad localizada RE/RP+ recibieron hormonoterapia adyuvante con buena adherencia y tolerancia. Dos de los once pacientes tratados con criterio radical recayeron en la evolución; el resto permanece en controles o tratamiento sin evidencia de recaída. Conclusión: presentamos una serie de pacientes con CMM, con un perfil similar al reportado en la literatura. La edad de presentación fue superior a la del CM femenino, y la mayoría fueron RE/RP +, HER 2-; sin embargo, en esta serie los pacientes se presentaron en estadio localizado y con tumores de alto grado en una proporción mayor a lo descrito en la literatura.

Breast cancer (BC) in men (MBC) is an uncommon clinical entity. Even though it shares some similarities with female BC, it has a distinctive profile. The objective of this study was to identify the characteristics of MBC and learn how it is managed in our setting. Materials and methods: retrospective study including patients diagnosed with MBC in three centers in Uruguay for a period of 15 years. Results: 12 patients were enrolled; the median age was 68 years; a third of whom had a family history (FH). Clinical and pathological characteristics: all of the tumors were ductal carcinomas of histological grade (HG) 2-3, 1/4 were stage (S) I, half (6) were SII, 6 had axillary metastases, 2/3 were estrogen receptor (ER) / progesterone receptor (PR) +. Three biological subtypes were defined: I) HER2- ER/PR+: 2/3 of patients; II) HER2+: 1/6; and III) triple-negative: 1/6. All patients with localized cancer underwent a mastectomy and most were treated with chemotherapy (CHT). All of those who presented with localized, ER/PR+ cancer received adjuvant hormone therapy, with good adherence and tolerance. Two of the eleven patients treated with radical surgery recurred during evolution; the rest remain in follow-up or treatment without evidence of recurrence. Conclusion: we presented a series of patients with MBC, with a profile similar to the one reported in the literature. Age at presentation was higher than that of female BC, and most were ER/PR +, HER 2-. However, patients in this series presented with breast cancer in the localized stage and high-grade tumors in a higher proportion than is described in the literature.

Breast cancer in men

Breast cancer in males is a relatively rare entity. In the sub-region, several reports indicate a higher incidence rate compared to other regions in the world. For many years, management strategies were derived from evidence based protocols established for managing female breast cancer. There are however,differences in the epidemiology, presentation, molecular profiles and response to therapies including chemotherapy, hormonal and targeted therapies. Outcomes even though mirroring female breast cancer may actually exhibit differences dependent onstage, race, prognostic and economic variables. The lack of large randomized trials on this subject has resulted in ad hoc management practices across the globe. With new information from renewed interest in the subject, screening and diagnostic guidelines are being established for high-risk groups and we expect to see improvement in outcomes for patients with male breast cancer. This article attempts to bring to light a summary of the current interest, recommendations and controversies in the management of male breast cancer

Sobrevida de pacientes con cáncer de mama y metástasis ósea / Survival of patients with breast cancer and bone metastasis

Introduction: Breast cancer is an important cause of death among female cancer in Chile. It metastasizes to any part of the body, being bone the first area of dissemination in 26-50 percent of cases and being found in 75 percent of patients dead from this cause. A median survival of 18 to 24 months is reported, and a probability of surviving 5 years of 20 percent. Therefore the objective of this study is to determine the difference of median survival depending on the presence of bone metastasis. Methods: A retrospective cohort study was conducted with 822 patients diagnosed with breast cancer between 2003 and 2010. The exposed cohort had scintigraphicly diagnosed bone metastasis, and the control group had no bone metastasis. Results: 8.88 percent of 822 patients, had bone metastasis. Those with bone metastasis had a mortality of 74 percent, and in the group with no bone metastasis, 16.69 percent died (p < 0.01). The median survival of patients with no metastasis was 44.3 months (IQR 35-83), and with metastasis was of 35 (IQR 18.6-46.1) (p < 0.01). With bone metastasis, over 48 months survival was 30.6 percent; and over 84 months 14.8 percent. Without bone metastasis, above 84 months, 78.51 percent survived (p < 0.01). Discussion and Conclusions: The difference between the two groups, considering global survival, is significant and implies an important decrease in survival and quality of life; the result obtained also differs from those reported in literature and it makes us reflect on the importance to consider bone metastasis not as a terminal event...

Introducción: El cáncer de mama es una importante causa de muerte por cáncer en las mujeres chilenas. Metastatiza a cualquier parte del cuerpo, siendo hueso la primera zona de diseminación en 26-50 por ciento de los casos, encontrándose un 75 por ciento de los pacientes que fallecen por esta causa. Se reporta una sobrevida de 18-24 meses, y una supervivencia a los 5 años del 20 por ciento. El objetivo del siguiente trabajo es determinar la sobrevida ante presencia de metástasis óseas. Pacientes y Método: Se realizó un estudio de cohortes retrospectivas con 822 pacientes diagnosticadas con cáncer de mama entre los años 2003 y 2010. La cohorte expuesta tiene diagnóstico cintigráfico de metástasis ósea, y la de control no tiene metástasis óseas. Resultados: 8,88 por ciento del total de 822 pacientes, presentó metástasis ósea. Con metástasis ósea existió una mortalidad del 74 por ciento, mientras que sin metástasis fue 16,69 por ciento (p < 0,01). La mediana de sobrevida sin metástasis ósea fue 44,3 meses (RIQ 35-83), en cambio, ante metástasis ósea fue 35 meses (RIQ 18,6-46,1) (p < 0,01). A los 48 meses, la supervivencia fue del 30,6 por ciento, para los pacientes con metástasis ósea y a los 84 meses, 14,8 por ciento, mientras que en los pacientes sin metástasis, la sobrevida a los 84 meses fue de 78,51 por ciento (p < 0,01). Discusión y Conclusiones: La diferencia de sobrevida entre pacientes con y sin metástasis ósea es significativa, implica una disminución en la supervivencia y la calidad de vida; difiere poco de lo reportado en la literatura, pero no debe hacernos considerar la metástasis ósea como un evento terminal de la enfermedad...

Breast Fine Needle Aspiration Cytology Reporting : A Study of Application of Probabilistic Approach.

Background: This study is based on application of probabilistic approach in reporting of breast fine needle aspiration cytology, its accuracy and correlation with likelihood of carcinoma in histology. Material and Method: Breast cytology was reported according to 1 of 6 categories, positive, suspicious, atypical, proliferative without atypia, unremarkable and unsatisfactory. Histologic correlation was done whenever possible. Results: Out of total 515 cases, 138 were correlated in histology. There were no false positive cases. The probability of finding carcinoma on histology, for suspicious and atypical categories was 94.11% and 75% respectively. All lesions from proliferative without atypia and unremarkable categories were benign on histology. Conclusion: The probabilistic approach is uniform, accurate method and easy to apply in reporting of breast FNAs. Suspicious and atypical categories were associated with increased incidence of carcinoma in histology and therefore such cases should be further evaluated for histology.

Histopathological Study of Neoplastic Lesions of Breast.

Aims and Objectives: 1) To study the incidence of various neoplastic lesions of breast. 2) To study the histopathological features of neoplasms and classify them according to WHO classification (2003). 3) To compare the results of study with those of other studies. Materials and Methods: The present study was prospective as well as retrospective which include 252 cases from October 2005 to October 2010. The specimens were received in different forms such as excisional biopsies, modified radical mastectomies, simple mastectomies, tru-cut biopsies, wide local excision and quadrantectomy specimens. Detail gross examination was done for each specimen and histopathological features were studied to classify neoplasms according to WHO classification 2003. Results: Out of total 9086 biopsies, breast biopsies were 366 (4%) during this 5 year study. Total 252 breast neoplasms were studied, where, the incidence of benign neoplasms was 50.4% (127 cases) & for malignant neoplasms was 49.6% (125 cases). Among all types of specimen received, excision biopsy was most common (48%). Upper outer quadrant was most commonly involved region for breast neoplasms. Fibroadenoma, benign phyllodes neoplasm, tubular adenoma, central papilloma, peripheral papilloma, lipoma and neurofibroma were seen among benign neoplasms. While invasive ductal carcinoma not otherwise specified, mixed carcinoma, metaplastic carcinoma, mucinous carcinoma, malignant phyllodes neoplasm, invasive lobular carcinoma, invasive papillary carcinoma, medullary carcinoma, intracystic papillary carcinoma, malignant peripheral nerve sheath neoplasm and collision neoplasm were studied among malignant neoplasms. The most common benign neoplasm was fibroadenoma (87%) and invasive ductal carcinoma not otherwise specified (88%) was malignant neoplasm. Conclusions: Fibroadenoma was the most common (87%) benign breast neoplasm. Among all malignant breast neoplasms, invasive ductal carcinoma, not otherwise specified was most common (88%). In cases of benign neoplasms, the highest incidence was found in the age group of 10-20 years (37%) while in the malignant neoplasms, it was 40 - 60 years (51.2%). The incidence of malignant breast neoplasm in male was 2.4%.

Cáncer de mama bilateral en hombre / Bilateral breast cancer in men

El cáncer de mama en hombres representa menos del 1% de los cánceres en el sexo masculino y casi el 1% de los cánceres de mama. Existe debido a su muy baja incidencia una falta de estudios clínicos aleatorizados. Desde el año 2008 hasta la fecha hemos diagnosticado cuatro cánceres en hombres, las edades comprendidas entre 49 y 61 años,correspondiendo a estadios IIB (2), in situ bilateral (1), IIIB(1), histológicamente eran: dos carcinoma ductal infiltrante, un Paget con nódulo palpable y un bilateral. El presente trabajo pretende dar a conocer el caso de un paciente masculino diagnosticado y tratado en nuestra institución, con cáncer de mama bilateral

The breast cancers in the men represent less than 1% of all cancers in the male population, and only 1% of all the breast cancers. Because his low incidence, there are absence of a randomized clinical studies. Since the 2008 years to the present, we were diagnoses for men breast cancers in the age between 49 and 61 years old. 2 corresponded to IIB stage, bilateral in situ (1) stage IIB (1), histological there are: 2 ductal and infiltrante, one Paget disease with palpable node an one bilateral. The present work is known a clinical case of male patient diagnoses and treatment in our institution with bilateral breast cancer

Male breast cancer in Indian patients: Is it the same.

Background: Cancer of the male breast accounts for about 1% of all malignancies in men and 1% of all breast cancers. Poor level of awareness often results in late presentation and delayed diagnosis in our environment. This study was done to analyse the demographic data, management and survival of male breast cancers in Indian subset of patients and compare it with that of western literature. Materials and Methods: A 10 year (2001-2010) retrospective study of all male breast cancers was done. Data regarding the incidence, presentation, histopathology, stage and grade of tumor, management and outcome of patients were analysed. Results: 26 cases of male breast cancer were encountered. This comprised 0.4% of all breast cancers seen in our department during the 10 year period. The ages of patients ranged from 45-75 years with a mean age of 57 years. Family history was present in 4 patients. Clinically, symptoms included self-detected lump in 23 (88.5%) patients, nipple retraction in 12 (46.1%) and pain in 12 (46.1%). All cases were unilateral (16 on right, 10 on left). Disease most commonly involved central quadrant (9 patients). Grade 3 disease was found in 13 patients and Stage 3 disease was most commonly encountered (13 patients). None of our patients received neo adjuvant chemotherapy. 20 (76.9%) patients had modified radical mastectomy and 6 (23.1%) had radical mastectomy. Most of our patients were hormone receptor positive (21 patients). Bilateral orchidectomy, Adjuvant chemotherapy, Adjuvant radiotherapy and Tamoxifen were offered in 3 (11.5%), 16 (61.5%), 17 (65.4%) and 15 (57.7%) patients respectively. Follow up ranged from 1-59 months. Conclusion: Male breast cancer is rare in our centre. Late presentation with advanced disease is a common feature in our environment. Further multiinstitutional, prospective studies are needed for better understanding of management of male breast cancers in Indian subset of patients.

Carcinoma papilar intraquístico asociado a adenocarcinoma ductal infiltrante en un hombre: reporte de un caso / Papillary intra cystic carcinoma associated to ductal infiltrant adenocarcinoma in male: a case report

El carcinoma papilar intraquístico es un subtipo de carcinoma ductal no invasivo, puede estar asociado o no a carcinoma in situ y a carcinoma infiltrante, es unapatología poco frecuente por tanto su aparición en hombres es extremadamente rara. El tratamiento en estos casos es equivalente al carcinoma de mama en mujeres, debatiéndose entre mastectomía simple o mastectomía parcial más radioterapia. Presentamos el caso de un hombre a quien se diagnostica preoperatoriamente con un carcinoma papilar y se realiza mastectomía simple más ganglio centinela

The papillary intra cyst carcinoma is a sub type of ductal no invasive carcinoma, it can be associated or no to carcinoma in situ and infiltrate carcinoma, is less frequent, for this reason his apparition in male is rare. The treatment in is equivalent to breast carcinoma in women, with two modalities of treatment: simple mastectomy or simple mastectomy with radiation therapy. We present clinical case of male whom is diagnostic pre surgery with a papillary carcinoma and realized simple mastectomy with sentinel node

Radioguided occult lesion localization versus wire-guided localization for non-palpable breast lesions: randomized controlled trial

AIM: This prospective randomized clinical study was conducted to compare radioguided occult lesion localization (ROLL) with wire-guided localization to evaluate optimum localization techniques for non-palpable breast lesions. METHODS: A total of 108 patients who were undergoing an excisional biopsy for non-palpable breast lesions requiring pathologic diagnosis were randomly assigned to the ROLL group (n = 56) and wire-guided localization group (n = 52). In the study, patients' characteristics, radiological abnormalities, radiological technique of localization, localization time, operation time, weight of the excised specimen, clearance margins, pathological diagnosis and perioperative complications were assessed. RESULTS: There were no differences between the two groups in terms of age, radiological abnormalities and localization technique (p = non-significant for all). ROLL techniques resulted in 100 percent retrieval of the lesions; for the wire-guided localization technique, 98 percent. Both localization time and operation time were significantly reduced with the ROLL technique (p = significant for all). The weight of the specimen was significantly lower in the ROLL group than in the wire-guided localization group (p = significant). The overall complication rate and pathological diagnosis were similar for both groups (p = non-significant for all). Clear margins were achieved in 91 percent of ROLL patients and in 53 percent of wire-guided localization patients, and the difference was significant. CONCLUSIONS: The present study indicated that the ROLL technique is as effective as wire-guided localization for the excision of non-palpable breast lesions. In addition, ROLL improved the outcomes by reducing localization and operation time, preventing healthy tissue excision and achieving clearer margins.

El objetivo del presente trabajo es presentar el comportamiento clínico patológico de 8 pacientes del sexo masculino con carcinoma de la mama, atendidos en el Instituto Oncológico "Dr. Luis Razetti" durante los años 2004-2005. El cáncer de mama en hombres representó el 2,33 por ciento, 37,5 por ciento fueron adenocarcinoma ductal infiltrante, 37,5 por ciento estadio IIIA, 87,5 por ciento se trató con mastectomías radicales modificadas, 57,25 por ciento expresan receptores de estrógenos, 28,57 por ciento sobre expresan Her2neu, 37,5 por ciento recibió adyuvancia, 62,5 por ciento con tamoxifeno, el seguimiento promedio fue de 44 meses, 37,5 por ciento de recaídas local y 62,5 por ciento están libres de enfermedad a los 5 años. El cáncer de mama en hombres es muy poco frecuente. El tratamiento primario es la cirugía, siguiendo los mismos lineamientos para la adyuvancia que en las mujeres.

The objective of the present work is analyzing the clinic pathologic status of 8 patients of sex male, attending in the Oncological Institute "Dr. Luis Razetti" during the 2004-2005 years. The breast cancer in male represented the 2.33 percent, in 37.5 percent of them were ductal infiltrante adenocarcinoma, 37.5 percent were state IIIA,87.5 percent were treated with surgery: Modified radical mastectomy, 57.25 percent express estrogen receptors, 28,57 percent over express Her2neu. 37.5 percent received adjuvant, 62.5 percent with tamoxifen, the average of periodic control was 44 month, and 37.5 percent of local recurrence and 62.5 percent of the patients are free of disease to 5 years. The breast cancer in male is less frequent. The primary treatment is surgery, with the same form to the adjuvant as in women.

The pathology of breast cancer in Jamaica: the national public health laboratory study / La patología del cáncer de mamas en Jamaica: estudio del laboratorio nacional de salud pública

OBJECTIVE: To document the pathologic features of breast cancer in Jamaica. METHODS: The pathology reports and slides of all patients diagnosed with breast cancer at the National Public Health Laboratory between January 1999 and December 2002 were reviewed. Patient age and gender, side involved, number of tumours identified, tumour size, histologic type, histologic grade, degree of lymph node involvement and parish of origin of the specimens were documented. RESULTS: There were 772 patients, 762 females and 10 males; age range 21 to 96 (mean 57.9 ± 15.9) years. There were 778 specimens (6 bilateral cases), the majority of whom originated from Kingston and St Andrew (34.7%). Manchester (22.9%), St Catherine (13.9%) and St Ann (7.3%) were the next most common sources. The left breast was involved in 50.5% of cases. Gross tumour was identified in 641 (82.4%) specimens, the number of tumours ranging from 1 - 6 (mean 1.1 ± 0.6). The maximum gross tumour dimension ranged from 0.3 to 15 cm (mean 4.1 ± 2.7 cm). Infiltrating duct carcinoma was the predominant histologic type (69.3 %); 13.3%, 49.5% and 37.2 % of all infiltrating tumours were well, moderately and poorly differentiated respectively. In-situ lesions (7.1% of tumours) were all of the ductal phenotype. Axillary lymph nodes were submitted in 296 (38.1%) cases; metastatic disease was identified in 224 (75.7%) of these. The total number of nodes submitted ranged from 1 - 34 (mean 10.8 ± 6.7) with an average of 6.1 (± 5.8) being positive for metastases (range 1 - 29). CONCLUSIONS: The pathologic features of breast cancer documented in this series including average tumour size, histologic types and grade and the degree of lymph node involvement are consistent with patient presentation at relatively advanced stages of disease and highlight the urgent need for public health intervention including a national screening programme.

OBJETIVO: Documentar los aspectos patológicos del cáncer de mamas en Jamaica. MÉTODOS: Se revisaron los reportes y diapositivas de patología de todas las pacientes diagnosticadas con cáncer de mamas en el Laboratorio Nacional de Salud Pública entre enero de 1999 y diciembre de 2002. Se documentaron la edad y el género de los pacientes, el lado afectado, el número de tumores identificados, el tamaño del tumor, el tipo histológico, el grado histológico, el nivel del nódulo linfático, y el distrito de origen de los especimenes. RESULTADOS: Hubo 772 pacientes (762 hembras y 10 varones); el rango de edad 21 a 96 (media 57.9 ± 15.9) años. Hubo 778 especimenes (6 casos bilaterales), la mayor parte de los cuales provenían de Kingston y St Andrew (34.7%). Manchester (22.9%), St Catherine (13.9%), y St Ann (7.3%) fueron las siguientes fuentes más comunes. La mama izquierda estaba afectada en el 50.5% de los casos. El tumor macroscópico se identificó en 641 (82.4%) especimenes, fluctuando el número de tumores de 1 - 6 (media 1.1 ± 0.6). La dimensión máxima del tumor macroscópico osciló de 0.3 a 15 cm. (media 4.1 ± 2.7 cm). El carcinoma ductal infiltrante fue el tipo histológico predominante (69.3%). El 13.3%, 49.5% y 37.2% de todos los tumores infiltrantes estaban bien, moderadamente y pobremente diferenciados respectivamente. Las lesiones in situ (7.1% de los tumores) fueron todas del fenotipo ductal. Nódulos linfáticos axilares fueron sometidos en 296 (38.1%) de los casos; la enfermedad metastática se identificó en 224 (75.7%) de éstos. El número total de nódulos sometidos fluctuó de 1 - 34 (media 10.8 ± 6.7) con un promedio de 6.1 (± 5.8) positivo a las metástasis (rango 1 - 29). CONCLUSIONES: Los aspectos patológicos del cáncer de mamas documentados en esta serie incluyendo el tamaño del tumor, el tipo histológico, y el grado y nivel de afectación del nódulo linfático, concuerdan con la presentación del paciente en etapas relativamente avanzadas de la enfermedad y subrayan la necesidad urgente de la intervención de la salud pública, incluyendo un programa nacional de pesquisaje.

Clinicopathological study of male breast carcinoma: 24 years of experience

Because breast cancer in men is rare, few patients are available for prospective studies. To learn more about its epidemiology, risk factors, clinical features, genetics and pathology in our country, we conducted a retrospective study of all cases seen in recent decades at our institution. We identified each case of male breast cancer in the database at the Sher-i-Kashmir Institute of Medical Sciences, Srinagar, Kashmir, India, between the years 1983 to 2007. We identified only 32 cases of male breast cancer over the 24-year period. Male breast cancer accounted for 32 [2.8%] of 1141 resected breast specimens, which included all breast lesions and 32 [4.1%] of 780 breast cancer cases. Of the 32 cases, 20 [62.5%] had various associated risk factors. Invasive ductal carcinoma was seen in 30 cases [93.7%]. Of 20 cases that underwent molecular studies, 16 [80%] patients had estrogen receptor positivity whereas 14 [70%] had progesterone receptor positivity. Six cases [30%] overexpressed HER2 and p53. The BRCA2 mutation was observed in 4 cases [40%] while no patient presented with the BRCA1 mutation. An incidence of 4.1% for male breast cancer indicates that this disease is not as uncommon as presumed in this part of the world. Breast cancer in men seems more frequently to be hormone receptor positive and the BRCA2 mutation confers a significant risk to men

Study of breast lump of 2246 cases by fine needle aspiration.

The purpose of this study was to analyze breast lesions causing breast lump with special reference to patients younger and older than 30 years of age diagnosed by fine-needle aspiration (FNA) and to evaluate the histology of the cases diagnosed as suspicious of malignancy in FNA. All patients who underwent FNA during four years period (2000-2004) were included in this study. The FNA procedure was performed and interpreted by the experienced pathologists. Histological evaluation of the suspicious cases in FNA was done and was based on excisional biopsy or mastectomy specimen. Out of 2246 FNA performed, 1840 were diagnosed as non-malignant, 6 atypical ductal hyperplasia, 52 suspicious of malignancy and 348 as malignant. The most common non-malignant lesions included 975 (43%) fibroadenosis, 180 (8%) fibroadenoma, 126 (6%) abscess and 96 (4%) fibrocystic changes. The patients were further divided into two groups: group I consisted of 918 patients aged 30 years and younger and group II consisted of 1328 patients above 30 years. In group I, 444 (48.4%) were diagnosed as fibroadenosis and only 15 (1.6%) cases were malignancies. In group II 531 (40%) were fibroadenosis and 333 (25%) were malignant. Patients more than 30 years old had significantly higher malignancy diagnoses (P<0.001). The odds of being diagnosed as malignant tumor among the higher age group patients (>30 years) is 21 times larger (confidence interval 12.4, 35.6) than the younger patients (<30 years). In 63% (27/43) of the suspicious cases, malignancy was diagnosed in histological examination. Cancer and Fibroadenosis are two most common causes of breast lumps in Nepal. Incidence of malignancy is significantly lower in patients aged 30 years and younger than in patients aged older than 30 years. Suspicious FNA cases should be evaluated histologically to rule out malignancy.

Câncer de mama masculino: uma doença diferente / Male breast cancer: a different disease

A câncer de mama em homens é uma doença pouco conhecida e, em razão de sua raridade, existem poucos ensaios clínicos e publicações abordando-o. Nosso objetivo é revisar a literatura focando a epidemiologia, os fatores de risco, a patologia e os marcadores tumorais do câncer de mama em homens. O câncer de mama em homens corresponde a 1% de todas as neoplasias da mama. Os fatores de risco incluem hiperestrogenismo, idade, ascendência judaica, história familiar, síndrome de Klinefelter. Os dados sobre patologia mostram que 90% dos tumores são ductais invasivos, 80% apresentavam receptores de estrógenos e 80% a 90%, receptores de progesterona positivos. O tratamento é extrapolado dos estudos sobre câmcer de mama feminino: cirurgia, hormonioterapia, quimioterapia e radioterapia são usados seguindo os guidelines femininos. Os fatores prognóstico incluem tamanho tumoral, grau histológico e comprometimento linfonodal. O câncer de mama é similar em homens e mulheres; todavia, os casos masculinos apresentam particularidades imunoistoquímicas, mas não existem estudos suficientes para avaliar o impacto dessa característica no prognóstico e tratamento dessa neoplasia.

Breast cancer in men is an unknown disease, because the rarity of the disease precludes large randomized trials and a great number of publications. Our goal is to review of the literature focusing on the epidemiology, risk factors, pathology and molecular markers and treatment of breast cancer in men. Carcinoma of the male breast accounts for 1% of all breast cancers. Risk factors include hiperestrogenism, age, Jewish ancestry, family history, and Klinefelter syndrome. Pathology data reviewed shown: 90% of tumors were invasive ductal carcinoma, 80% of tumors were estrogen receptor positive, 80% to 90% were progesterone receptor positive. Treatment is extrapolated from female studies: surgery, adjuvant hormonal therapy, radiotherapy and chemotherapy, using the same guidelines as for women. Prognostic factors include tumor size, histological grade, and lymph node status. Breast cancer is similar in men and women; however, breast cancer in men has imuno-histochemistry particularities and there is no enough studies regarding the impact of such differences in prognosis, treatments strategies
