ABSTRACT

El Tumor Desmoide, es un tumor raro de origen mesenquimal con una incidencia aproximada de 0.3% (1) que, si bien es considerado un tumor benigno por no presentar metástasis a distancia, se considera un tumor localmente agresivo con altas tasas de recidiva tras la extirpación quirúrgica de entre el 19 a 28% (2). Se presenta el caso clínico de una mujer de 21 años de edad, gestante de 7 semanas, que acudió a consulta a la Unidad de Mastología del Hospital de Clínicas por percatarse de nódulo en cuadrante superoexterno de mama derecha, que aumenta de tamaño. Se realizó exéresis tumoral con márgenes, cuyo diagnóstico fue un Tumor Desmoide y, posterior resección de márgenes para ampliación. El Tumor Desmoide es poco frecuente de localización mamaria, que fue tratada con cirugía con buena evolución en una mujer gestante, por lo que debe considerarse esta patología en pacientes jóvenes gestantes, como diagnóstico diferencial en nódulos mamarios.


Desmoid tumor is a rare tumor of mesenchymal origin with an approximate incidence of 0.3% (1). Although it is considered a benign tumor because it does not present distant metastases, it is considered a locally aggressive tumor with high rates of recurrence after surgical removal of between 19 to 28% (2). We present the clinical case of a 21-year-old woman, 7 weeks pregnant, who attended the Mastology Unit of the Hospital de Clínicas, after noticing a nodule in the upper outer quadrant of the right breast, which was increasing in size. Tumor excision with margins was performed, whose diagnosis was a Desmoid Tumor, and subsequent resection of margins for amplifying The Desmoid Tumor is rare in the breast and was treated with surgery with a good evolution in a pregnant woman, so this pathology should be considered in young pregnant patients, as a differential diagnosis in breast nodules.

ABSTRACT

Introducción: El adenoma tubular de mama una patología benigna que se presenta en mujeres jóvenes como una masa unilateral que genera asimetría mamaria y se tiende a confundir con fibroadenoma gigante juvenil, diferenciándose en el estudio histopatológico. Es una patología muy rara, con excepcionales casos reportados en la literatura de mayor a 10 cm, motivo de presentación de este caso. Caso clínico: Presentamos el caso de una mujer de 21 años de edad con una masa de10 cm aproximadamente en la mama derecha, de 1 año de evolución con crecimiento paulatino, sin síntomas asociados. El examen físico sin hipertrofia de ganglios axilares. Taller diagnóstico: La paciente fue sometida a una exéresis quirúrgica reportando en el estudio patológico definitivo un adenoma tubular de mama. Conclusión: Como conclusión se trata de una patología poco frecuente, pero debemos conocerla y tener un mínimo de sospecha diagnóstica para evitar confusiones con patología mamaria maligna.


Introduction: Tubular adenoma of the breast is a benign pathology in young women as a unilateral mass that generates breast asymmetry and tends to be confused with giant juvenile fibroadenoma, differing in the histopathological study. It is a very rare pathology, with exceptional cases reported in the literature of greater than 10 cm, which is the reason for presenting this case. Clinical case: We present the case of a 21-year-old woman with a mass of approximately 10 cm in the right breast, of 1 year of evolution with gradual growth, without associated symptoms. Physical examination showed no axillary node hypertrophy. Diagnostic workshop: The patient underwent surgical excision, reporting a tubular adenoma of the breast in the definitive pathological study. Conclusion: It is a rare pathology, but we must know it and have a minimum of diagnostic suspicion to avoid confusion with malignant breast pathology.

ABSTRACT

El angiosarcoma es un tumor vascular maligno poco frecuente. Constituye menos del 2% de todos los sarcomas. Existen varias formas clínicas, una es la producida después de radioterapia, en pacientes que fueron tratadas por un cáncer de mama, con cirugía conservadora y radioterapia. Se presenta como un sarcoma de alto grado, localizado en la piel o en el tejido subcutáneo y, ocasionalmente, el parénquima mamario. El único tratamiento curativo es la cirugía, con tendencia a la recurrencia y a hacer metástasis hematógena, el pronóstico es malo, con alta tasa de mortalidad.


Angiosarcoma is a rare malignant vascular tumor. It constitutes less than 2% of all sarcomas. There are several clinical forms; the one produced after radiation therapy is that associated with patients who were treated for breast cancer with conservative surgery and radiation therapy. It presents as a high-grade sarcoma located on the skin or the subcutaneous tissue and, occasionally, the breast parenchyma. The only curative treatment is surgery, with a tendency to recurrence and visceral hematogenous metastasis, with a poor prognosis and a high mortality rate.

ABSTRACT

Resumo Objetivo relatar a experiência de indução da lactação em nuligestas realizada por enfermeira consultora em aleitamento. Método relato de experiência. O processo de indução láctea foi realizado com três mulheres por motivo de gestação em útero de substituição e relacionamento homoafetivo. Resultados todas perceberam o aumento de tamanho e a sensibilidade nas mamas, bem como apresentaram secreção láctea. No entanto, a continuidade da amamentação foi diferenciada entre elas. A primeira não recebeu apoio de profissionais de saúde no contexto de pós-parto hospitalar, nem em casa, e não deu continuidade à amamentação. A segunda recebeu apoio da equipe do hospital e da parceira, amamentando por três meses. A terceira, com o apoio da parceira, amamentou por dois meses, mas interrompeu por sentir-se inibida por familiares. Conclusão e implicações para a prática a técnica de indução é capaz de desencadear a produção láctea. Já o processo de amamentação só se estabeleceu mediante a associação com a rede de apoio, o acolhimento, o incentivo da equipe de saúde e o olhar integral à mulher e sua família. Dessa forma, o cuidado de Enfermagem na indução láctea não deve focar apenas no manejo da indução, mas transcender o aspecto técnico, o que se mostra como fundamental para a proteção, o estabelecimento e a continuidade da amamentação.


Resumen Objetivo reportar la experiencia de inducir la lactancia en nuligestas realizada por una consultora de enfermería en lactancia materna. Método relato de experiencia. El proceso de inducción de la leche se realizó con tres mujeres por embarazo en útero de reemplazo y relación homoafectiva. Resultados todas notaron el aumento de tamaño y la sensibilidad en las mamas, además de presentar secreción de leche. Sin embargo, la continuidad de la lactancia materna se diferencia entre ellos. La primera no recibió apoyo de los profesionales de la salud en el contexto posparto hospitalario, ni en el domicilio, y no continuó con la lactancia. La segunda recibió apoyo del personal del hospital y su pareja, amamantando durante tres meses. La tercera, con el apoyo de su pareja, amamantó durante dos meses, pero la interrumpió porque se sentía inhibida por familiares. Conclusión e implicaciones para la práctica la técnica de inducción es capaz de desencadenar la producción de leche. El proceso de lactancia materna, en cambio, solo se estableció a través de la asociación con la red de apoyo, la acogida, el estímulo del equipo de salud y la mirada integral a la mujer y su familia. Así, el cuidado de Enfermería en la inducción de la leche no debe enfocarse solo en el manejo de la inducción, sino trascender el aspecto técnico, que se muestra fundamental para la protección, el establecimiento y la continuidad de la lactancia materna.


Abstract Objective to report the experience of lactation induction in women who never got pregnant by a lactation consultant nurse. Method experience report. The process of lactation induction was performed with three women due to surrogate pregnancy and homosexual relationships. Results all noticed an increase in the size and sensitivity of the breasts, as well as milk secretion. However, the continuity of breastfeeding was different between them. The first did not receive support from health professionals in the postpartum hospital setting, nor at home, and did not continue breastfeeding. The second received support from the hospital staff and her partner, breastfeeding for three months. The third, with the support of her partner, breastfed for two months, but stopped because she felt inhibited by family members. Conclusion and implications for practice the induction technique is capable of triggering milk production. However, the breastfeeding process was only established through the association with the support network, the reception, the encouragement of the health team, and the comprehensive view of the woman and her family. Thus, nursing care in lactation induction should not focus only on the management of induction, but transcend the technical aspect, which is essential for the protection, establishment, and continuity of breastfeeding.

ABSTRACT

OBJECTIVE@#To investigate the value of quantitative synthetic magnetic resonance imaging (SyMRI) in distinguishing between benign and malignant breast lesions.@*METHODS@#We retrospectively collected data of preoperative conventional MRI and multi-dynamic multi-echo sequences from 95 patients with breast lesions showing mass-type enhancement on DCE-MRI, including 27 patients with benign lesions and 68 with malignant lesions. The MRI features of the lesions (shape, margin, internal enhancement pattern, time-signal intensity curve, and T2WI signal) were analyzed, and for each lesion, SyMRI-generated quantitative parameters including T1 and T2 relaxation time and proton density (PD) were measured before and after enhancement and recorded as T1p, T2p, PDp and T1e, T2e, and PDe, respectively. The relative change rate of each parameter was calculated. Logistic regression and all-subset regression analyses were performed for variable selection to construct diagnostic models of the breast lesions, and receiver-operating characteristic (ROC) analysis was used to assess the performance of each model for differentiation of benign and malignant lesions.@*RESULTS@#There were significant differences in the MRI features between benign and malignant lesions (P < 0.05). All the SyMRI-generated quantitative parameters, with the exception of T2e and Pdp, showed significant differences between benign and malignant lesions (P < 0.05). Among the constructed diagnostic models, the model based on all the DCE-MRI features combined with SyMRI parameters T2p and T1e (DCE-MRI+T2p+T1e) showed the best performance in the differential diagnosis malignant breast masses with an AUC of 0.995 (95% CI: 0.983-1.000).@*CONCLUSION@#Quantitative SyMRI can be used for differential diagnosis of benign and malignant breast lesions.

ABSTRACT

OBJECTIVES@#Accurate breast lesion surface localization can guarantee accurate biopsy and local treatment. But there is no guideline to regular equipment and methods for the localization of breast lesions. The conventional non-invasive localization method is marker-based localization. The advantages of this method are simple and efficient. The disadvantages are that markers disappear easily under coupling agents; the positioning length of markers cannot last long on skin; and healthcare associated infection due to many patients using the same marker pen is potentially unavoidable. Breast lesion sticker (called sticker for short) is a new-type localization medical instrument in 2020. Our study aims to explore the clinical value of a new lesion stickers in breast lesion surface localization via comparison of the sticker and marker pen localization methods.@*METHODS@#This was a prospective cohort study. It was conducted in 67 patients who needed breast lesion surface localization before biopsy. The patients were randomly assigned into 2 groups. One group of patients used marker pen to mark breast lesion surface location by ultrasonography. The other group of patients used stickers. Patients labeled with markers on skin were swabbed agents before marking. Then the markers were checked by ultrasound scan. If the surface positions of breast lesion were not correct, the above procedure was repeated. In the sticker group, the stickers were released synchronously after the lesions were detected by ultrasound scan. Then locations were checked via scanning hole. If the surface positions of breast lesion were not correct, the above procedure was repeated. The accuracy of positioning, the length of positioning time and satisfaction of patients between the 2 groups were compared. The length of positioning time was calculated from the time when ultrasound detected the lesion to the time when the surface position of breast lesion was confirmed. The total score of patients' satisfaction was 5 points according to Service Quality Evaluation of SERVQUAL Scale, including sonographers' service attitude and their technical proficiency, other medical staffs' service attitude and their technical proficiency, hospital service procedures, positioning comfort, and positioning effects.@*RESULTS@#All 67 patients were females, aged 18-66 (39.73±13.10). There were 35 patients in the marker pen group and 32 patients in the sticker group. The time length of group used marker pen to localization was 22-88 (52.20±2.90) s, and the sticker group was 3-15 (9.22±0.58) s in length. The length of positioning time for the stickers was significantly shorter than that of the marker (P<0.01). Both methods were accurate in the surface localization of lesions before operation. The total scores of patients' satisfaction was 4-5 (4.92±0.02) in the stickers group, and 1-5 (3.35±0.10) in the marker pen group. The patients' satisfaction scores with the sticker were significantly higher than those with the marker pen (P<0.01). The length of positioning time and patients' satisfication scores for sonographer with 20 years' working experience were shorter and higher than those of sonographer with 10 years' working experience, respectively (both P<0.05).@*CONCLUSIONS@#The new breast lesion positioning stickers have more advantages than the marker pen in localization efficiency. It could reduce the workload of medical workers and increase patients' satisfaction to some extent. The stickers can be used not only in the breast lesions surface localization, but also in the skin location of pleural effusion and ascites, the skin location of surface masses, the skin location of thyroid nodule, and many other clinical marker areas, to further expand the scope of clinical application and value of the stickers.

ABSTRACT

Clinical applications of cone-beam breast CT(CBBCT) are hindered by relatively higher radiation dose and longer scan time. This study proposes sparse-view CBBCT, i.e. with a small number of projections, to overcome the above bottlenecks. A deep learning method - conditional generative adversarial network constrained by image edges (ECGAN) - is proposed to suppress artifacts on sparse-view CBBCT images reconstructed by filtered backprojection (FBP). The discriminator of the ECGAN is the combination of patchGAN and LSGAN for preserving high frequency information, with a modified U-net as the generator. To further preserve subtle structures and micro calcifications which are particularly important for breast cancer screening and diagnosis, edge images of CBBCT are added to both the generator and the discriminator to guide the learning. The proposed algorithm has been evaluated on 20 clinical raw datasets of CBBCT. ECGAN substantially improves the image qualities of sparse-view CBBCT, with a performance superior to those of total variation (TV) based iterative reconstruction and FBPConvNet based post-processing. On one CBBCT case with the projection number reduced from 300 to 100, ECGAN enhances peak-signal-to-noise ratio (PSNR) and structural similarity (SSIM) on FBP reconstruction from 24.26 and 0.812 to 37.78 and 0.963, respectively. These results indicate that ECGAN successfully reduces radiation dose and scan time of CBBCT by 1/3 with only small image degradations.

ABSTRACT

Early screening is an important means to reduce breast cancer mortality. In order to solve the problem of low breast cancer screening rates caused by limited medical resources in remote and impoverished areas, this paper designs a breast cancer screening system aided with portable ultrasound Clarius. The system automatically segments the tumor area of the B-ultrasound image on the mobile terminal and uses the ultrasound radio frequency data on the cloud server to automatically classify the benign and malignant tumors. Experimental results in this study show that the accuracy of breast tumor segmentation reaches 98%, and the accuracy of benign and malignant classification reaches 82%, and the system is accurate and reliable. The system is easy to set up and operate, which is convenient for patients in remote and poor areas to carry out early breast cancer screening. It is beneficial to objectively diagnose disease, and it is the first time for the domestic breast cancer auxiliary screening system on the mobile terminal.

ABSTRACT

OBJECTIVE@#To evaluate the value of ultrasound S-Detect in the diagnosis of breast masses.@*METHODS@#A total of 85 breast masses in 62 female patients were diagnosed by S-Detect technique and conventional ultrasound. The diagnostic efficacy of conventional ultrasound and S-Detect technique was analyzed and compared with postoperative pathological results as the gold standard.@*RESULTS@#When operated by junior physicians, the diagnostic efficacy of conventional ultrasound was significantly lower than that of S-Detect technique (P < 0.05), but this difference was not observed in moderately experienced and senior physicians (P>0.05). S-Detect technique was positively correlated with the diagnostic results of senior physicians (r=0.97). Using S-Detect technique, the diagnostic efficacy did not differ significantly between the long axis section and its vertical section (P>0.05). Routine ultrasound showed a better diagnostic efficacy than S-Detect for breast masses with a diameter below 20 mm (P < 0.05), but for larger breast masses, its diagnostic efficacy was significantly lower than that of SDetect (P < 0.05).@*CONCLUSION@#S-Detect can be used in differential diagnosis of benign and malignant breast masses, and its diagnostic efficiency can be comparable with that of BI-RADS classification for moderately experienced and senior physicians, but its diagnostic efficacy can be low for breast masses less than 20 mm in diameter.

ABSTRACT

Abstract Carcinoma of the mammary crease is a very rare variant of breast carcinoma, in which the skin lesions are usually the presenting sign. The authors present the case of an 88-year-old woman with an exophytic plaque in the mammary crease of approximately ten years duration. The histopathological and immunohistochemical studies confirmed the diagnosis of infiltrative breast carcinoma (carcinoma of the mammary crease variant). This case highlights the important role of the dermatologist in the early diagnosis of this rare variant of breast cancer.

Resultados: la prevalencia en la muestra fue de 4.7%; todos los casos fueron en mujeres, la media de edad fue 55,5 años; el motivo de consulta más frecuente fue alteración en la imagen de mama (n=79, 54.9%), el tamaño medio de la lesión fue 1,9 cm (rango 0,1-20). Se encontró discordancia entre el diagnóstico por biopsia cortante y el espécimen de patología en 70 (48.6%) casos, en estos se encontró infraestimación de lesiones con mayor riesgo en el 36,1% (n=52). Según la clasificación histológica, el tipo más frecuente de lesión fue el papiloma intraductal 34.7% (n=50), seguido por el carcinoma papilar en 11,8% (n=17). El tipo de cirugía más efectuado fue la cuadrantectomía, con un 68.7% (n=99). La media de seguimiento fue de 28.5 meses y se encontró recaída en siete casos (4.9%). Conclusión: las lesiones papilares comprenden un grupo heterogéneo, que incluye desde las benignas hasta aquellas con potencial maligno. Afectan a las mujeres en la quinta década de la vida, se presentan como una masa, pequeña, unilateral, sin predominio de lateralidad, de crecimiento lento. El tratamiento óptimo para las lesiones de riesgo y con atipias es la cirugía con márgenes negativos, el riesgo de recurrencia es clínicamente relevante.


Objective: to describe the sociodemographic data, the clinical and paraclinical ma-nifestations, the treatment and the recurrence, in a group of patients diagnosed with papillary lesions.Methodology:analytical study of a retrospective cohort with secondary sources of information from users' medical records in the period of January 1, 2016 to December 31, 2019. The demographic, clinical and paraclinical data collected were analyzed using descriptive statistics.Results:the prevalence in the sample was 4.7%; all cases were women, the mean age was 55.5 years; the most frequent reason for consultation was abnormal breast imaging examination (n=79, 54.9 %), the mean size was 1.9 cm (range 0,1-20). Disagreement was found between the diagnosis by sharp biopsy and the pathology specimen in 48.6% of cases (n=70); lesion underestimation with higher risk was found in 36.1% of them (n=52). According to the histological classification, the most frequent was intraductal papilloma in 34.7% (n=50), followed by papillary carcinoma in 11.8% (n=17). The type of surgery most performed was quadrantectomy, 68.7% (n=99). The mean follow-up was 28.5 months and relapse was found in 4.9% (n=7).Conclusion:papillary lesions comprise a heterogeneous group, with a spectrum that includes both benign lesions and those with malignant potential. The lesions affect women in their fifties. They become apparent as a small, unilateral mass, without a pre-dominance of laterality, and of slow growth. The optimal treatment in risk lesions and with atypia is surgery with negative margins. The risk of recurrence is clinically important.

ABSTRACT

Abstract Objective: Breast surgery is considered a clean surgery; however, the rates of infection range between 3 and 15%. The objective of the present study was to intraoperatively investigate the presence of autochthonous microbiota in the breast. Methods: Pieces of breast tissue collected from 49 patients who underwent elective breast surgery (reconstructive, diagnostic, or oncologic) were cultured. The pieces of breast tissue were approximately 1 cm in diameter and were removed from the retroareolar area, medial quadrant, and lateral quadrant. Each piece of tissue was incubated in brain heart infusion (BHI) broth for 7 days at 37°C, and in cases in which the medium became turbid due to microorganism growth, the samples were placed in Petri dishes for culturing and isolating strains and for identifying species using an automated counter. Results: Microorganism growth was observed in the samples of 10 of the 49 patients (20.4%) and in 11 of the 218 pieces of tissue (5%). The detected species were Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus epidermidis, Sphingomonas paucimobilis, and Aeromonas salmonicida. No patient with positive samples had clinical infection postoperatively. Conclusion: The presence of these bacteria in breast tissue in approximately 20% of the patients in this series suggests that breast surgery should be considered a potential source of contamination that may have implications for adverse reactions to breast implants and should be studied in the near future for their oncological implications in breast implant-associated large-cell lymphoma etiology.


Resumo Objetivo: A cirurgia de mama é considerada uma cirurgia limpa; entretanto, as taxas de infecção variam entre 3 e 15%. O objetivo deste estudo foi investigar no intraoperatório a presença de microbiota autóctone na mama. Métodos: Pedaços de tecido mamário coletados de 49 pacientes submetidas à cirurgia eletiva da mama (reconstrutiva, diagnóstica ou oncológica) foram cultivados. Os pedaços de tecido mamário tinham aproximadamente 1 cm de diâmetro e foram removidos da área retroareolar e dos quadrantes medial e lateral. Cada pedaço de tecido foi incubado em caldo BHI (brain heart infusion) por 7 dias a 37 ° C, e nos casos em que o meio ficou turvo devido ao crescimento de microrganismos, as amostras foram colocadas em placas de Petri para cultivo e isolamento de cepas e para identificação de espécies usando um contador automatizado. Resultados: O crescimento do microrganismo foi observado nas amostras de 10 das 49 pacientes (20,4%) e em 11 dos 218 pedaços de tecido (5%). As espécies detectadas foram Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus epidermidis, Sphingomonas paucimobilis e Aeromonas salmonicida. Nenhum paciente com amostras positivas apresentou infecção clínica no pós-operatório. Conclusão: A presença dessas bactérias no tecido mamário em aproximadamente 20% das pacientes desta série sugere que a cirurgia mamária deve ser considerada uma fonte potencial de contaminação que pode ter implicações nas reações adversas aos implantes mamários e deve ser estudada em um futuro próximo por suas implicações oncológicas na etiologia do linfoma de células grandes associado ao implante de mama.

Objective: To characterize the patients with mammary hypertrophy to whom reduction mastoplasty was practiced with the inferior pedicle technique. Methods: A descriptive, observational, cross-sectional and retrospective study of 185 patients between 10 and 59 years, with diagnosis of mammary hypertrophy was carried out. They were assisted in the Plastic Surgery and Caumatology Service of Octavio de la Concepción y de la Pedraja Teaching General Hospital from the municipality of Baracoa, to whom reduction mastoplasty by inferior pedicle technique was practiced, from January, 2004 to December, 2020. Results: In the series there was a prevalence of the females between 30-39 years (42.8 %), the cosmetic results with good evaluation (90.3 %), few complications (20.0 %), with primacy of the skin necrosis in the inferior space of the flap union (7.0 %) and the patients satisfied with the procedure (93.5 %). The dried up glandular tissue varied in less than 300 grams and more than 1 200, according to the degree of hypertrophy. Conclusions: The mammary reduction technique to inferior pedicle is versatile, safe and applicable to all types of hypertrophy, with a low rate of complications; also it offers favorable cosmetic results and high degree of satisfaction.

ABSTRACT

RESUMO A Eribulina é um quimioterápico para o tratamento de câncer de mama metastático avançado. Os casos de distúrbios respiratórios e torácicos por toxicidade como a doença intersticial pulmonar são raros, e representam menos de 1% dos efeitos adversos. Neste relatos, apresentamos um caso raro de pneumonia intersticial durante o tratamento com eribulina em um paciente com câncer de mama avançado, A pneumonia induzida por drogas relacionada a eribulina foi diagnosticada com base em achados clínicos e tomográfico. Após tratamento com corticosteroides a paciente teve evolução positiva do quadro respiratório e melhora no exame de imagem tomográfica. PALAVRA-CHAVE: Câncer, mama, eribulina


ABSTRACT Eribulin is a chemotherapeutic for the treatment of advanced metastatic breast cancer. Cases of respiratory and thoracic disorders due to toxicity such as interstitial lung disease are rare, and represent less than 1% of adverse effects. In these reports, we present a rare case of interstitial pneumonia during treatment with eribulin in a patient with advanced breast cancer. Drug-induced pneumonia related to eribulin was diagnosed based on clinical and CT findings. After treatment with corticosteroids, the patient had a positive evolution of the respiratory condition and improvement in the CT scan. KEYWORDS: Cancer, breast, eribulin

ABSTRACT

Introducción: El subtipo luminal de cáncer de mama es sensible a la terapia antiestrógenica y muestra un mejor pronóstico que el del cáncer de mama con receptor del factor de crecimiento epidérmico humano 2 enriquecido (HER2) o triple negativo. Sin embargo, el cáncer de mama tipo luminal es heterogéneo y puede tener características clínicas agresivas. Investigamos las implicaciones clínicas y pronósticas de la baja expresión del receptor de estrógeno en un grupo de carcinomas luminales HER2 negativos. Material y método: Recolectamos los datos de un grupo de 367 cánceres de mama luminales HER2 negativo que eran receptor de estrógeno (RE) positivos y receptor de progesterona (RP) positivos o negativos y los dividimos en RE+ alto (RE) y RE+ bajo (REB). Se definió REB de acuerdo a la úl- tima actualización ASCO /CAP de las recomendaciones del testeo de de RH en cáncer de mama como aquellos con expresión entre 1 y 10%. Analizamos los datos clínico-patológicos y la supervivencia según los grupos de RE y REB. Resultados: Edad media 63,9+12.8 años. Tamaño tumoral: 1,9 +0.9 cm. Se realizó Mastectomía radical modificada en 61% de los pacientes. Tipo histológico más frecuente: Ductal Infiltrante en 89,5% de los casos. Hallazgos que concuerdan con publicaciones de otros centros. Discusión: Los tumores REB resultaron en 1,6%. No hubo diferencias estadísticas en el estadio TNM y tipo histológico. Sin embargo, el grupo REB se asoció con menor edad (47 vs 57 años), tipo luminal B, mayor grado histológico y Ki 67 alto (>30%). Si bien las diferencias en supervivencia global (SG) no fueron significativas (p=0,279), observamos que a partir de los 60 meses de seguimiento la SG fue menor en el grupo REB que en el grupo RE. Conclusiones: La baja expresión del RE se asoció peor pronóstico. Podríamos considerar la baja expresión del RE como marcador pronóstico en el subtipo luminal HER2 negativo de cáncer de mama. Debido a la baja incidencia de casos REB consideramos necesario estudios adicionales con mayor número de pacientes que podrían revelar su papel negativo en el cáncer de mama.


Introduction: The luminal subtype of breast cancer is sensitive to antiestrogenic therapy and shows a better prognosis than human epidermal grow- th factor receptor 2 (HER2) enriched or triple negative breast cancer. However, luminal type breast cancer is heterogeneous and can have aggressive clinical features. We investigated the clinical and prognostic implications of low estrogen receptor expression in a group of HER2-negative luminal carcinomas. Material and method: We collected data from a group of 367 HER2 negative luminal breast cancers that were estrogen receptor (ER) positive and progesterone receptor (PR) positive or negative and divided them into ER + high (ER) and ER + low (ERL). ERL was defined when RE expression was < 10%. We analyzed the clinical-pathological data and survival accor- ding to the ER and ERL groups. Results: ERL tumors resulted in 1.6%. There were no statistical differences in TNM stage and histological type. However, the ERL group was as- sociated with younger age (47 vs 57 years), luminal type B, higher histological grade, and high Ki 67 (> 30% ). Although the differences in overall survival (OS) were not significant (p = 0.279), we observed that after 60 months of follow-up the OS was lower in the ERL group than in the ER group. Conclusions: Low ER expression was associated with a worse prognosis. We could consider low ER expression as a prognostic marker in the HER2-ne- gative luminal subtype of breast cancer. Due to the low incidence of ERL cases, we consider necessary additional studies with a larger number of patients that could reveal its negative role in breast cancer.

ABSTRACT

Objetivo: reportar el caso de una paciente con diagnóstico de tejido mamario ectópico en vulva, y realizar una revisión de la literatura acerca del diagnóstico, tratamiento y pronóstico de esta condición en esta localización. Materiales y métodos: paciente de 49 años consulta por masa vulvar dolorosa a un centro privado de nivel medio de complejidad ubicado en Bogotá, Colombia. Se realizó ecografía de la lesión y posteriormente escisión quirúrgica; la histopatología mostró tejido mamario ectópico sin malignidad. Se realizó una búsqueda en las bases de datos PubMed, Embase, Cochrane, LILACS y Scielo, con las palabras clave "Vulva", "Glándulas mamarias", "ectópico", "Vulva", "Breast" y "Ectopic", y se incluyeron reportes y series de caso de mujeres con tejido mamario en vulva confirmado por histopatología. Resultados: se identificaron 184 títulos, de los cuales 94 fueron finalmente incluidos para un total de 126 casos. El 57,9% eran tumores benignos, con un 95% en mujeres menores de 50 años; y el 42,06% eran tumores malignos, el 92 % en mujeres mayores de 50 años. El diagnóstico se realizó por clínica, con imágenes diagnósticas complementarias, marcadores tumorales e inmunohistoquímica en algunos casos. Se realizó escisión local en el 91% de los casos de patología benigna y 43% de patología maligna, siendo el método diagnóstico y terapéutico. Conclusión: el tejido mamario ectópico en vulva debe ser considerado como parte del diagnóstico diferencial de masas a nivel vulvar con diferente pronóstico en mujeres pre y posmenopáusicas. Se requieren más estudios para una mejor caracterización de la patología y definir el tratamiento ideal en términos de recaída y supervivencia.


Objective: To report the case of a patient diagnosed with ectopic mammary tissue in the vulva, and to conduct a literature review of the diagnosis, treatment and prognosis of this condition in that location. Material and methods: A 49-year-old patient who presented with a painful vulvar mass to a private intermediate complexity center in Bogotá, Colombia. The lesion was assessed on ultrasound and then surgically excised; histopathology showed ectopic mammary tissue with absence of malignancy. A search was conducted in the PubMed, Embase, Cochrane, LILACS and Scielo databases using the keywords "Vulva," "Breast" and "Ectopic." Case reports and case series of women with histopathology-confirmed mammary tissue in the vulva were included. Results: Overall, 184 titles were identified and, of these, 94 were ultimately included, for a total of 126 cases, with 57.9% being benign tumors, 95% in women under 50 years of age, and 42.06% being malignant tumors, 92% in women over 50 years of age. Diagnosis was made on the basis of the clinical findings, with ancillary diagnostic imaging, tumor markers and immunohistochemistry in some cases. Local excision was performed in 91% of cases with benign pathology and in 43% of cases with malignant pathology, with the diagnostic method being therapeutic. Conclusion: Ectopic mammary tissue in the vulva must be considered as part of the differential diagnosis of vulvar masses, prognosis being different in pre and postmenopausal women. Further studies are needed to enhance the characterization of this condition and define the ideal course of treatment in terms of relapse and survival.

ABSTRACT

SUMMARY OBJECTIVE To explore the values of automated breast volume scanning (ABVS) combined with shear wave elastography (SWE) in the differential diagnosis of triple-negative breast cancer (TNBC) and human epidermal growth factor receptor 2-positive breast cancers (HER2+BC). METHODS In this study, 28 patients with TNBC and 32 patients with HER2+BC were enrolled. The characteristics of ABVS and virtual touch quantification (VTQ) in SWE of all patients were reviewed. The multivariate logistic regression analysis was carried out and the receiver operating characteristic curves of ABVS and ABVS+VTQ were drawn. RESULTS In ABVS imaging, the microcalcification, posterior echo, internal echo, shape, and edge had significant difference between TNBC and HER2+BC groups (p<0.05). The regular shape was the independent factor for TNBC (p=0.04, odds ratio [OR]=4.479), and the microcalcification in mass was the independent factor for HER2+BC (p=0.01, OR=2.997). In VTQ imaging, the shear wave velocity (SWV)max, SWVmin, and SWVmean in TNBC group were significantly lower than those in HER2+BC group (p<0.001). The sensitivity, specificity, and accuracy of ABVS+VTQ in diagnosing TNBC were higher than those of ABVS alone. CONCLUSIONS ABVS combined with SWE has certain advantages in differentiating TNBC from HER2+BC, which is helpful for the treatment planning and prognosis judgment.

ABSTRACT

Se realizó un estudio con diseño cuantitativo, de tipo observacional descriptivo; cuya población de estudio estuvo constituida por 142 pacientes de sexo femenino, diagnosticadas con cáncer de mama en la Unidad Oncológica Solca-Chimborazo, durante el período 2014-2019; con el objeti - vo de describir el tratamiento fisioterapéutico en ese contexto de investigación. Los datos fueron recolectados a partir de las respectivas historias clínicas. A partir de 2015, se observó un predo- minio de pacientes adultos con edades comprendidas entre 36 y 65 años. De las 142 pacientes que conformaron la población estudiada, solo 5 desarrollaron linfedema posquirúrgico. La mayoría de las pacientes incluidas en el estudio fueron intervenidas quirúrgicamente (65); 59 de las cuales recibieron tratamiento de drenaje linfático manual. Entre la población elegida en la Unidad Oncológica de Solca-Chimborazo se evidenció que la aplicación de terapia de rehabili - tación mediante drenaje linfático manual posquirúrgico reduce la posibilidad de aparición de linfedema a largo plazo.


This research aimed to describe the physiotherapeutic treatment in this research context. A study was carried out with a quantitative design, of a descriptive observational type. The study popula- tion consisted of 142 female patients, diagnosed with breast cancer at the Solca-Chimborazo Oncology Unit, during the period 2014-2019. The data were collected from the respective medi- cal records. Since 2015, a predominance of adult patients aged between 36 and 65 years was observed. From the 142 patients that made up the study population, only 5 developed postsurgi- cal lymphedema. Most of the patients included in the study underwent surgery (65); 59 received manual lymphatic drainage treatment. Among the population chosen in the Solca-Chimborazo Oncology Unit, it was evidenced that the application of rehabilitation therapy through postope- rative manual lymphatic drainage reduces the possibility of long-term lymphedema develop - ment.
