Caracterización de los resultados de biopsia por trucut en pacientes con BI-RADS 4 y 5 sin criterio quirúrgico

Introducción: La biopsia percutánea se ha convertido, en nuestros días, en el método diagnóstico más utilizado para la evaluación de las lesiones de mama sospechosas de malignidad. Objetivo: Caracterizar los resultados de biopsia por trucut en pacientes con categorías BI-RADS 4 y 5 sin criterio quirúrgico. Materiales y métodos: Se realizó un estudio observacional, descriptivo y transversal de 70 pacientes que presentaron lesión sospechosa de malignidad por ultrasonografía y que requirieron la realización de biopsia por aguja gruesa de la imagen reportada, entre enero de 2019 y diciembre de 2020. Se realizaron en la Consulta de Intervencionismo Mamario del Departamento de Imagenología del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas. Se analizaron las variables edad, categoría BI-RADS, resultado histopatológico, tamaño tumoral y complicaciones. Resultados: El grupo etario predominante fue el de 70-79 años (27,1). Se clasificaron 48 pacientes con categoría BI-RADS 5, para un 68,6 %. El carcinoma ductal infiltrante resulto ser el tipo histológico predominante, con 40 pacientes, representando el 57,1 % del total. Se obtuvo una media de 28,91 mm de diámetro de las lesiones biopsiadas. Todas las muestras resultaron útiles, aun en diámetros transversales inferiores a 2 cm. En la serie, las complicaciones reportadas fueron escasas. Conclusiones: La biopsia realizada con aguja gruesa bajo guía ecográfica con técnica de manos libres, es un método confiable para el diagnóstico de cáncer de mama, seguro y sin complicaciones graves. Se confirma que la categoría BI-RADS 5 coincide con diagnóstico histopatológico de cáncer mamario.

Introduction: Percutaneous biopsy has become, nowadays, the most used diagnostic method to evaluate breast lesions suspected of malignancy. Objective: To characterize the Tru-cut biopsy results in patients with BI-RADS 4 and 5 categories without surgical criteria. Materials and methods: An observational, descriptive and cross-sectional study was carried out between January 2019 and December 2020 on 70 patients who presented who presented a lesion suspicious of malignancy by ultrasonography and required a thick-needle biopsy of the reported image. They were performed at the Breast Intervention Clinic of the Imaging Department of the Clinical Surgical University Hospital Comandante Faustino Pérez Hernández, from Matanzas. The variables age, BI-RADS category, histopathological result, tumor size and complications were analyzed. Results: The predominant age group was the 70-79 years-old one (27.1). 48 patients were classified with BI-RADS 5 category, for 68.6%. Infiltrating ductal carcinoma resulted the predominant histological type, with 40 patients representing 57.1% of the total. An average diameter of 28.91 mm was obtained from the biopsied lesions. All samples were useful, even in transverse diameters less than 2cm. In the series, few complications were reported. Conclusion: Biopsy performed with thick needle under ultrasound guidance with free-hands technique, is a reliable method for breast cancer diagnosis, safe and without serious complications. It is confirmed that BI-RADS 5 category coincides with breast cancer pathological diagnosis.

Polyclonal antibody-induced downregulation of HER1/EGFR and HER2 surpasses the effect of combinations of specific registered antibodies.

Background: Antitumor therapies targeting HER1/EGFR and HER2, such as monoclonal antibodies (MAbs) and tyrosine-kinase inhibitors (TKIs), have demonstrated a significant clinical benefit, but the emergence of resistance limits long-term efficacy. While secondary HER1 mutations confer tolerance to TKI, compensatory upregulation of HER2 drives resistance to anti-HER1 MAbs, which identifies MAb combinations targeting both receptors as an attractive therapeutic strategy. Nevertheless, toxicity hampers the clinical validation of this approach. Alternatively, cancer vaccines may induce antibodies directed against several antigens with less concern about induced toxicity. Methods: Polyclonal antibodies (PAbs) targeting HER1 and HER2 were induced in mice or rabbits through immunization. Recognition of different epitopes on targets by PAbs was validated by phage-display technology. Receptor downregulation was evaluated by flow cytometry, immunofluorescence, and Western blot. MTT assays assessed cytotoxicity, while the antitumor effect of PAbs was assayed in nude mice. Results: PAbs promoted degradation of HER1 and HER2 regarding clinical MAbs or their combinations. As a result, inhibition of cytotoxicity on tumor cell lines was improved, even in the presence of oncogenic mutations in HER1, as well as in cetuximab-insensitive cells. Accordingly, the antitumor effect of vaccination-induced PAbs was observed in lung tumor lines representative of sensitivity or resistance to HER1 targeting therapies. Conclusions: Immunization against HER1 and HER2 receptors offers an alternative to passive administration of combinations of MAbs, since vaccination-induced PAbs promote the downregulation of both receptors and they have a higher impact on the survival of tumor cells.

Immuno-toxicological evaluation of her1 cancer vaccine in non-human primates: a 6-month subcutaneous study.

Purpose: A vaccine composition based on the extracellular domain of the human epidermal growth factor receptor 1 (HER1-ECD) and the combination of VSSP (very small size proteoliposomes) and Montanide ISA 51 adjuvants when used by intramuscular route, demonstrated promising results in preclinical studies. However, in order to avoid potential adverse events due to the use of Montanide, it is proposed to modify the vaccine formulation by using VSSP (very small size proteoliposomes) adjuvant alone, and to evaluate the quality of subcutaneously induced immune response. This study aimed to assess the immunotoxicological effects of HER1 vaccine in Cercopithecus aethiops.Materials and methods: Fifteen monkeys were randomized into four groups: Negative Control (Tris/NaCl, s.c.), Positive Control (200 µg HER1-ECD/VSSP/Montanide ISA-51 VG, i.m), Low Dose (200 µg HER1-ECD/VSSP/Tris NaCl, s.c.) and High Dose (800 µg HER1-ECD/VSSP/Tris NaCl, s.c). All monkeys received 7 doses and were daily inspected for clinical signs. Body weight, rectal temperature, cardiac and respiratory rates were measured during the study, and electrocardiographical and ophthalmological studies were performed. Humoral and cellular immune response and clinical pathology parameters were analyzed.Results: Animal's survival in the study was 100% (n = 15). Administration site reactions were observed in the Positive Control animals (n = 4). HER1 vaccine administered subcutaneously (High Dose Group) achieved good IgG antibody titers although lower than the Positive Control group, but with higher ability to inhibit HER1 phosphorylation. Conclusions: This suggests that the alternative of eliminating the use of Montanide in the HER1 vaccine preparation and the using subcutaneous route is feasible.

HER1-based vaccine: Simultaneous activation of humoral and cellular immune response.

The human epidermal growth factor receptor 1 (HER1) is a tumor-associated antigen that has been validated as a clinical target for several passive, non-immune therapies currently approved for the treatment of epithelial tumors. HER1 is an oncogene that not only promotes tumor progression and survival, but also immune escape. Its overexpression in some epithelial malignancies has been correlated with a poor prognosis. We developed an approach to target HER1 by specific active immunotherapy, recognizing the extracellular domain of the receptor, using a combination of VSSP and Montanide ISA 51 as adjuvants. We summarize the results obtained with this vaccine in both the preclinical and clinical settings, emphasizing the importance of the induction of both humoral and cellular responses for the success of cancer vaccines as safe therapeutic alternatives for the treatment of cancer.

Síndrome de Sézary. Presentación de un caso / Sézary síndrome. Case presentation

RESUMEN El síndrome de Sézary constituye la fase leucémica de la micosis fungoide caracterizado por eritrodermia, adenopatías superficiales y células atípicas en sangre. Predomina en los hombres con una proporción 2/1 respecto a las mujeres, y en las edades entre los 60 y 70 años de edad. La enfermedad es de difícil tratamiento, con un pronóstico reservado por su baja supervivencia. Por ser infrecuente y su posible similitud con otras dermatosis, se presenta un caso con antecedentes de psoriasis vulgar con 5 años de evolución, que hacía aproximadamente 6 meses, se encontraba sin mejoría en brote de agudización a pesar de los tratamientos indicados (AU).

ABSTRACT Sezary syndrome is the leukemic part of the fungoid mycosis, characterized by erythroderma, surface adenopathies and atypical cells in blood. It predominates in men with a 2/1 proportion in respect to women, and in ages ranging from 60 to 70 years. It is a difficult treated disease, with a reserved prognosis because of the low survival. Due to its infrequency and possible similarity to other dermatosis, it is presented a case with antecedents of vulgar psoriasis of 5 years evolution, without improvement for around 6 months, in acute outbreak in spite of the indicated treatments (AU).

Anti-proliferative and pro-apoptotic effects induced by simultaneous inactivation of HER1 and HER2 through endogenous polyclonal antibodies.

The human epidermal growth factor receptor (HER1) and its partner HER2 are extensively described oncogenes and validated targets for cancer therapy. However, the effectiveness of monospecific therapies targeting these receptors is hampered by resistance emergence, which is frequently associated with the upregulation of other members of HER family. Combined therapies using monoclonal antibodies or tyrosine kinase inhibitors have been suggested as a promising strategy to circumvent this resistance mechanism. We propose an alternative approach based on simultaneous inactivation of HER1 and HER2 by multi-epitope blockade with specific polyclonal antibodies induced by vaccination. Elicited antibodies impaired both receptors activation and induced their degradation, which caused the inhibition of down-signaling cascades. This effect was translated into cell cycle arrest and apoptosis induction of human tumor cells. Elicited antibodies were able to reduce the viability of a panel of human tumor lines with differential expression levels of HER1 and HER2. The most significant effects were obtained in the tumor lines with lower expression levels of both receptors. These new insights would contribute to the rational design of HER receptors targeting multivalent vaccines, as an encouraging approach for the treatment of cancer patients.

Adenoma pleomórfico de glándula lagrimal ectópica / Pleomorphic adenoma of ectopic tear glands

El adenoma pleomórfico es una de las neoplasias más frecuentes que puede originarse en la glándula lagrimal, pero su origen en tejido ectópico subconjuntival, palpebral e intraocular ha sido escasamente reportado. Se presentó el caso de una paciente femenina de 60 años con tumor en órbita anterior de 4 meses de evolución, localizado por encima del párpado superior, dolorosa, firme, de 8 mm de superficie lisa, con Tomografía Axial Computarizada que informa proceso quístico V/S neoformativo. Se realizó biopsia excisional donde se encuentra nódulo tumoral bien delimitado de composición bifásica con abundante matriz cartilaginosa y mixoide, elementos mioepiteliales, epiteliales ductales y escamosos lo que establece el diagnóstico definitivo de adenoma pleomórfico. El tejido lagrimal ectópico constituye un dilema y una neoplasia originada en ellos constituye mayor problema aun. Los avances en la cirugía oftalmológica han permitido el diagnóstico y cirugía temprano de lesiones tumorales de esta localización para beneficio de los pacientes.

The pleomorphic adenoma is one of the most frequent neoplasia that could be originated in the tear gland, but its origin in subconjunctival, palpebral and intraocular tissue has been scarcely reported. We present the case of a female patient aged 60 years with a hard, painful tumor in anterior orbit of fourth months’ evolution, located over the higher eyelid, of 8 mm plain surface; the computerized axial tomography shows a neoformative cystic V/S process. We carried out scissional biopsy finding a well-delimitated, biphasic-composition tumoral nodule with large amount of cartilaginous and mixed, myoepithelial, ductal epithelial and squamous elements, helping to establish the definite diagnosis of pleomorphic adenoma. The ectopic lacrimal tissue is a dilemma and neoplasia originated in them is still a bigger problem. The advances in ophthalmologic surgery have allowed the early diagnosis and surgery of the tumoral lesions in this location for the patients’ sake.

Tumor glómico gástrico. Reporte de un caso / Gastric glomic tumor. Report of a case

El tumor glómico es un tumor mesenquimatoso tipo vascular benigno. Se origina de la modificación de las células de músculo liso del cuerpo gnómico, que son comúnmente observados en el dermis o en tejido células subcutáneo. Su aparición es rara en el tracto gastrointestinal. Se presentó el caso de un paciente masculino de 62 años de edad que acude por acidez y dolor en epigastrio al que se le realiza endoscopia con hallazgo de masa tumoral de 3 cm cubierto por mucosa sana localizado en cara posterior de cuerpo gástrico. Fue realizado estudio de rayos X contrastado, biopsia por ponchamiento y, posteriormente, gastrectomía subtotal. El estudio histopatológico demostró un tumor glómico gástrico, se le concluyó su estudio con la aplicación de inmunohistoquimica. Por las dificultades para su diagnóstico preoperatorio y constituir el estudio histopatológico la única forma de determinar la naturaleza de esta lesión submucosa gástrica con sus características típicas, se decidió presentar este caso, posiblemente el primero diagnosticado en Cuba.

The glomic tumor is mesenchymal tumor of benign vascular type. It arises from the modification of the cells of the plain muscles of the gnomic body, commonly observed in the dermis or in subcutaneous cellular tissues. It is rarely found in the gastrointestinal tract. We presented the case of a male patient, aged 62 years, who assisted the consultation because of sourness and epigastrium pain. As a result of an endoscopy we found a 3 cm tumoral mass covered by healthy mucous located on the back side of the gastric body. A contrasted X-rays study, a biopsy by puncture, and a subtotal gastrectomy were carried out. The histopathologic study showed a glomic gastric tumor, and its study was ended with the application of immunohistochemistry. Because of the difficulties for its pre surgical diagnosis, and because the histopathologic study is the unique form of determining the nature of this gastric submucous lesion with its typical characteristics, we decided to present this case, probably the first one diagnosed in Cuba.

Tiroiditis granulomatosa de De Quervain: diagnóstico por citología con aspiración por aguja fina / De Quervain's granulomatous thyroiditis: diagnosis by cytology with thin needle

La tiroiditis de De Quervain, también nombrada como tiroiditis subaguda o tiroiditis de células gigantes, frecuentemente es precedida por un cuadro infeccioso del tracto respiratorio superior. Su diagnóstico es eminentemente clínico; pero el uso de la citología por aspiración con aguja fina de tiroides, confirma o niega el planteamiento clínico según las características citológicas. Fue empleada esta técnica en 6 pacientes con clínica y ultrasonido diferentes y por la necesidad de realizar un correcto diagnóstico diferencial con otras formas de hipertiroidismo con peor pronóstico evolutivo. La citología por aspiración con aguja fina mostró en estos casos ser un arma eficaz para ello, por lo que se decidió realizar esta presentación.

De Quervain's thyroiditis, also called sub-acute thyroiditis or thyroiditis of giant cells, is frequently preceded by an infectious picture of the high respiratory tract. Its diagnosis is eminently clinical; but the usage of the cytology by aspiration of the thyroid with thin needle, confirm or denied the clinical conclusions according to the cytological characteristics. This technique was used in six patients with different clinical and ultrasound results, because of the necessity of arriving to a correct differential diagnosis with other forms of hyperthyroidism with worse evolvable diagnosis. The cytology by aspiration with thin needle in these cases showed to be an efficacious weapon for that, so we decided to prepare this presentation.

Impacto de factores pronósticos y predictivos del cáncer de mama en laUnidad Oncológica Provincial, de Matanzas / Prognostic and predictive factors of the breast cancer impact at the Matanzas Provincial Oncology Unit

Se realizó un estudio descriptivo de prevalencia o corte transversal, para valorar factores pronósticos y predictivos del cáncer de mama a partir de recidivas en 496 mujeres tratadas en la Unidad Oncológica Provincial de Matanzas, remitidas por hospitales provinciales y territoriales, desde enero de 2004 hasta diciembre de 2008. Se recogieron los datos mediante encuestas aplicadas a historias clínicas e informes de biopsias, procesadas por Sistema Epi Info versión 6.04. Hubo mayor incidencia de cáncer de mama en mujeres postmenopáusicas y mayor agresividad en premenopáusicas. Casi la mitad de las pacientes se diagnosticaron en etapa precoz y existió alto índice de recidivas, sobre todo en etapas avanzadas. El carcinoma lobulillar invasivo se destacó con más recidivas, mientras el tubular poseyó mejor pronóstico. Por su parte, el carcinoma ductal in situ y el lobular in situ presentaron más recurrencias que lo esperado. La cirugía conservadora exhibió mayor número de recidivas a distancia que la mastectomía radical modificada, mientras ésta mostró recidivas locales (2,1 por ciento) y las primeras, ninguna. La conservadora se relacionó con alto porcentaje de persistencia de la enfermedad, en la cual influyeron los bordes de sección comprometidos. El estatus ganglionar, tamaño tumoral y grado histológico se destacaron como los principales factores pronósticos anátomo-patológicos, no así los receptores hormonales. Existió buena respuesta al tamoxifeno y a ciclos de ciclofosfamida, metrotexate y 5 flouracilo. Se concluye demostrando la influencia de los factores pronósticos y predictivos modificables y no modificables sobre el alto índice de recidivas, y recomendando medidas para mejorar dichos indicadores...

We carried out a descriptive study of prevalence or cross sectional study to assess predictive and prognostic factors of the breast cancer from recidivism in 406 women treated at the Matanzas Provincial Oncology Unit, and remitted from provincial and territorial hospitals, since January 2004 to December 2008. Data were collected from clinical records and biopsy informs, processed with the Epi Info System, Version 6.04. There was a higher incidence of the breast cancer in post-menopausal women and a higher aggressiveness in pre-menopausal women. Almost half of the patients were diagnosed in the precocious stage and there was a high index of recidivism, mainly in advanced stages. The invasive lobular carcinoma presented more recidivists, while the tubular one had a better prognosis; the ductal carcinoma in situ and the lobular carcinoma in situ had more recurrences than they were expected. The conservative surgery showed a higher number of recidivists in distance than the modified radical mastectomy, while the last one showed local recidivism (2,1 por ciento) and the first, no one; the conservative one was related with a high percent of disease persistence, in which the compromised section edges. The ganglion status, tumour size and histological level were pointed out as the main anatomic-pathological prognosis facts, but not the hormonal receptors. There it was a good answer to tamoxifen and to CMF (cyclophosphamide, metothrexate and 5 flouracil) cycles. In conclusion, we demonstrated the influence of the modifiable and non-modifiable prognostic and predictive facts on the high index of recidivism and recommend taking measures to improve those indicators...

Tumor del Estroma Gastrointestinal(GIST): presentación de un caso / Gastrointestinal estromal tumor: presentation of a case

Desde las primeras descripciones de Golden y Stout6, este grupo de lesiones mesenquimales se consideraron de origen muscular y recibieron nombres como leiomioma, leiomioma celular, leiomioma epitelioide, leiomioblastoma, leiomioma bizarro y leiomiosarcoma. No es, sin embargo, hasta la utilización de la inmunohistoquímica y la subsiguiente demostración de la ausencia de marcadores musculares y la presencia ocasional de marcadores neurales, que surge de la mano de Mazur y Clark3 el término de tumores del estroma. Actualmente se denominan GISTs a los tumores mesenquimales CD117.positivos, fusiformes o epitelioides, primarios del tracto gastrointestinal, epiplon, mesenterio y retroperitoneo10. Los GISTs aparecen en la pared del tubo digestivo: estómago (50-60 por ciento), intestino delgado (20-30 por ciento), intestino grueso (10 por ciento) y esófago (5 por ciento) y ocasionalmente en epiplon, mesenterio y retroperitoneo (5 por ciento). En nuestro trabajo se presenta a una paciente de 67 años de edad que fue ingresada en nuestro centro por presentar un cuadro de sangramiento digestivo alto, estudiada, y se comprobó una tumoración del fundus gástrico de 6 cm , se operó y los resultados definitivos de anatomía patológica arrojaron un Tumor del Estroma Gastrointestinal.

Since the first descriptions made by Golden and Stout, this group of mesenchymal lesions is considered of muscular origin and they were named as leiomyoma, cellular leiomyoma, epithelioid leiomyoma, leiomyoblastoma, bizarre leiomyoma and leiomyosarcoma. But Mazur and Clark created the term estromal tumor only after they began to use the inmunohistochemistry and subsequently showed the absence of muscular markers, and the occasional presence of neural markers. Nowadays, gastrointestinal estromal tumors are called the primary mesenchymal CD117.positive, fusiform or epithelioid tumors of the gastrointestinal tract, epiplon, mesenterio, and retroperitoneum. The gastrointestinal estromal tumors appear at the wall of the digestive tube: stomach (50-60 percent), small intestine (20-30 percent), large intestine (10 percent) and esophagus (5 percent), and occasionally in epiplon, mesenterio, and retroperineum (5 percent). In our work we present a 67 year-old patient, entered in our hospital for presenting high digestive bleeding. We studied the case, and found a 6 cm tumor of the gastric fundus. The tumor was operated and.

The gastrointestinal estromal tumors appear at the wall of the digestive tube: stomach (50-60 percent), small intestine (20-30 percent), large intestine (10 percent) and esophagus (5 percent), and occasionally in epiplon, mesenterio, and retroperineum (5 percent). In our work we present a 67 year-old patient, entered in our hospital for presenting high digestive bleeding. We studied the case, and found a 6 cm tumor of the gastric fundus. The tumor was operated and(AU)

Adenocarcinoma colónico originado en adenoma túbulo velloso asociado a endometriosis intestinal: a propósito de un caso / Malign tubule-hairy adenoma synchronized with intestinal endometriosis: a case proposal

Paciente femenina, blanca, de 56 años de edad, con historia de infertilidad por endometriosis pélvica y sangramiento digestivo bajo al defecar. Se realiza rectosigmoidoscopia y se visualiza lesión polipoidea de aproximadamente 3 cm pediculada. Se realiza resección y se analiza por biopsia, la cual informa adenoma tubulovelloso con áreas de adenocarcinoma bien diferenciado. Se repite la colonoscopia y biopsia de esa área la cual informa adenocarcinoma. Se decide intervenir quirúrgicamente realizándose rectosigmoidectomía por video laparoscopia. La biopsia informa no presencia de tumor y endometriosis de la pared del recto sigmoides. Se presenta el caso de forma ilustrativa y se revisa lo hasta ahora reportado.

A white, 56-years-old female patient, with a history of infertility caused by pelvic endometriosis and low digestive bleeding when defecating was attended. We made a rectosigmoidioscopy and found a tumoral hairy lesion of around 3 cm. A resection was made and a biopsy, resulting a tubule-hairy adenoma with a well-differentiated adenocarcinoma areas. We repeated the colonoscopy and biopsy of this area, showing adenocarcinoma as a result. We decided the surgical intervention making a rectosigmoidectomy by video laparoscopy. The biopsy showed neither tumor nor endometriosis at the recto sigmoid wall. We present the case in an illustrative way and reviewed the existent literature.
