ABSTRACT

RESUMEN Introducción: El cáncer de vejiga es un tumor mucho más frecuente de lo que a veces nos transmiten las estadísticas o los medios de comunicación. Ocupa el noveno lugar en cuanto al número de diagnósticos de cáncer a nivel mundial y se reporta aproximadamente cinco veces más frecuente en varones que en mujeres. Objetivo: Describir las características clínico-patológicas de los tumores malignos del tracto urinario inferior. Método: Se realizó un estudio descriptivo y transversal de 186 pacientes con tumores malignas del tracto urinario inferior diagnosticados anatomo-patológicamente en el Hospital Provincial Clínico Quirúrgico Docente "Saturnino Lora Torres", de Santiago de Cuba, entre los años 2017 al 2020. Una vez recopilados los datos se procesaron mediante el sistema estadístico SPSS, en su versión 21.0. Resultados: En la serie la mayoría de los afectados fueron hombres entre los 60 y 79 años de edad, siendo más frecuente en el sexo masculino. Predominaron los carcinomas uroteliales con el 96,4 % del total en su variedad papilar y de alto grado de malignidad. Conclusiones: Los tumores malignos del tracto urinario inferior son un problema de salud de baja frecuencia cuya trascendencia es la afectación individual a quien lo padece, y su comportamiento clínico patológico, en sentido general, fue similar a lo reportado por la literatura nacional e internacional, salvo pequeñas y puntuales diferencias relativo a los síntomas, el diagnóstico histológico, en parte, y el grado de malignidad de las lesiones.


ABSTRACT Introduction: Bladder cancer is a more common tumor that sometimes the statistics database or media conveyed to us. It ranks ninth concerning cancer diagnoses worldwide and it is reported to be approximately five times more frequent in males than in females. Objective: To describe the clinicopathologic features of malignant lower urinary tract tumors. Method: A descriptive and cross-sectional study involving a total of 186 patients was conducted. Anatomical and pathological diagnoses were carried out to all patients with malignant lower urinary tract tumor at the Hospital Provincial Clínico Quirúrgico Docente "Saturnino Lora Torres" in Santiago de Cuba, from 2017 throughout 2020. Once the data were collected, they were processed using the SPSS statistical system, version 21.0. Results: Most affected patients with lower urinary tract tumor had an average age of 60 to 70, arising most frequently in males. The 96.4 % of the total of the patients were diagnosed with urothelial carcinomas (predominant), described in its papillary variety and the high degree of malignant transformation. Conclusions: Malignant lower urinary tract tumors are health problems labeled as the low frequency which differ in their transformation according to the patient. The clinical pathological behavior of the tumor, in a general sense, was similar to that reported in the national and international literature, except for small and pointed differences regarding symptoms, histological diagnosis, and the degree of the lesions´ malignant transformation.


RESUMO Introdução: O câncer de bexiga é um tumor mais comum do que às vezes o banco de dados de estatísticas ou a mídia veiculada por nós. Ele ocupa o nono lugar em diagnósticos de câncer em todo o mundo e é relatado ser aproximadamente cinco vezes mais frequente em homens do que em mulheres. Objetivo: Descrever as características clínico-patológicas dos tumores malignos do trato urinário inferior. Método: Foi realizado um estudo descritivo e transversal envolvendo um total de 186 pacientes. Os diagnósticos anatômicos e patológicos foram realizados a todos os pacientes com tumor maligno do trato urinário inferior no Hospital Provincial Clínico Quirúrgico Docente "Saturnino Lora Torres" em Santiago de Cuba, de 2017 a 2020. Uma vez coletados os dados, eles foram processados ​​no SPSS sistema estatístico, versão 21.0. Resultados: A maioria dos pacientes afetados com tumor do trato urinário inferior tinha uma idade média de 60 a 70 anos, surgindo mais frequentemente no sexo masculino. 96,4% do total dos pacientes foram diagnosticados com carcinomas uroteliais (predominantes), descritos em sua variedade papilar e alto grau de transformação maligna. Conclusões: Os tumores malignos do trato urinário inferior são problemas de saúde rotulados como de baixa frequência e que diferem em sua transformação de acordo com o paciente. O comportamento clínico-patológico do tumor, de um modo geral, foi semelhante ao relatado na literatura nacional e internacional, exceto por pequenas e pontuadas diferenças quanto à sintomatologia, ao diagnóstico histológico e ao grau de transformação maligna das lesões.

ABSTRACT

ABSTRACT Upper tract urothelial carcinoma (UTUC) is a rare and aggressive disease that is associated with high rates of recurrence and death. Radical nephroureterectomy (RNU) with excision of the bladder cuff is considered the standard of care for high-risk UTUC, whereas kidney-sparing techniques can be indicated for select patients with low-risk disease. There is a significant lack of clinical and pathological prognostic factors for stratifying patients with regard to making treatment decisions. Incorporation of tissue-based molecular markers into prognostic tools could help accurately stratify patients for clinical decision-making in this heterogeneous disease. Although the number of studies on tissue-based markers in UTUC has risen dramatically in the past several years—many of which are based on single centers and small cohorts, with a low level of evidence—many discrepancies remain between their results. Nevertheless, certain biomarkers are promising tools, necessitating prospective multi-institution studies to validate their function.

ABSTRACT

Local recurrence after radical nephroureterectomy (RNU) owing to urothelial carcinoma of the upper urinary tract is rare. The usual treatment is systemic chemotherapy followed by optional resection of the mass. We introduce the case of a 73-year-old male patient with multiple comorbidities in whom retroperitoneal carcinoma recurrence of 31 mm was diagnosed via positron emission tomography-computed tomography scan with 18-fluorodeoxyglucose about 5 years after he had undergone RNU owing to urothelial carcinoma of the upper urinary tract. The patient was treated with computed tomography-guided percutaneous radiofrequency ablation. Later scans with contrast controls showed lack of contrast uptake and a decrease of the lesion's size. Twenty-four months after the procedure, the patient is free of the disease. To date, this is the first case of recurrence of urothelial carcinoma that was treated with percutaneous radiofrequency ablation, thus establishing an alternative to chemotherapy in patients with substantial comorbidities.

ABSTRACT

Background: Prostatic adenocarcinoma and urothelial carcinoma of the urinary bladder are common cancers in men. High grade forms of these tumors may present ambiguous morphologic features that do not permit a definite diagnosis. This distinction between the two tumors has significant staging and therapeutic implications. Hence, an accurate diagnosis is essential for optimal patient care. p63 is a new marker which can be used in this context. It is expressed in most of the urothelial carcinomas and negative in majority of prostatic adenocarcinomas. Aim: To compare the expression of p63 in urothelial carcinomas and adenocarcinomas of prostate. Materials and Methods: Comparative cross--sectional study was carried out at a tertiary cancer hospital from 15 June 2006 to 15 December 2006. Immunohistochemical stain p63 was performed on 50 cases of urothelial carcinoma and 50 prostatic adenocarcinomas. Patients' name, age, histology numbers, grade of tumor, and expression of p63 were recorded. p63 expression was seen in 44 of 50 urothelial carcinomas (88%). None of the prostatic adenocarcinomas expressed p63. The ages of patients with prostatic adenocarcinoma ranged from 49 to 86 years with a median age of 71 years and 41 to 83 years for urothelial carcinomas with a median age of 60.5 years. Conclusion: p63 can be used as a reliable marker to distinguish prostatic adenocarcinomas from urothelial carcinomas in difficult cases in conjunction with other markers like PSA.

ABSTRACT

This study aimed to investigate the relationship of caveolin-1 expression with prognosis in patients with transitional cell carcinoma of the upper urinary tract (TCCUUT). Formalin-fixed, paraffin-embedded tissue sections of TCC-UUT from 98 patients, who had undergone radical nephroureterectomy, were stained immunohistochemically using antibodies against caveolin-1. The expression pattern of caveolin- 1 was compared with the clinicopathological variables. The caveolin-1 expression was significantly correlated with T stage (p<0.001) and grade (p=0.036). The survival rate of patients with caveolin-1 positive tumors was significantly lower than that of patients with caveolin-1 negative tumors (p<0.0001). The univariate analyses identified T stage, grade, and caveolin-1 expression as significant prognostic factors for cancer-specific survival, whereas the multivariate analyses indicated that T stage and caveolin-1 expression were independent prognostic factors. These results show that the increased expression of caveolin-1 is associated with tumor progression and poor prognosis in TCC-UUT, suggesting that caveolin-1 may play an important role in the progression of TCC-UUT.

ABSTRACT

Originalmente es posible hacer el diagnóstico de ca in situ de los tractos urinarios superiores que precede al desarrollo de un tumor invasor de CT o que puede ser seguido de ca in situ de la vejiga o el sistema colector del riñón contralateral por lo que es muy importante el segumiento de estos pacientes con citologías de orina con TACs y el tratamiento profiláctico con BCG para prevenir esta progresión o recurrencia del ca in situ en otra parte del epitelio transicional del aparato urinario. Aquí se reporta el primer caso diagnosticado en el Servicio de Urología del HSJD como ca in situ de pelvis renal y uretero superior, que fue tratado co una nefroureterectomía laparoscópica, por no poder hacerse el diangóstico preoperatoriamente, lo cual hubiera permitido su observación después de ser tratado con BCG y seguido con TACs periódicos.

ABSTRACT

Se sabe que en los tumores sólidos ocurren frecuentemente cambios en el contenido de ADN, que reflejan cambios genéticos a nivel cromosómico, los que juegan un papel importante en el desarrollo y progresión de los mismos. El estudio citogenético de los tumores sólidos ha mostrado un cariotipo complejo, que ha dificultado la identificación de los cambios cromosómicos específicos. Sin embargo la genética molecular ha identificado a algunos genes asociados con la carcinogenesis y sus alteraciones en los tumores. La citometría de flujo se ha utilizado ampliamente en el análisis del contenido y distribución del ADN en tumores, tanto experimentalmente como en clínica, y relacionarlo en el pronóstico y su progresión. Su aplicación en oncología ha sido muy vasta, principalmente en ginecología, urología y gastroenterología, y se ha concentrado en la identificación de tumores en su estadio inicial y en su pronóstico. En este simposio se presentan la metodología empleada y los resultados obtenidos en el cáncer mamario, prostático y vesical principalmente

ABSTRACT

La citología urinaria constituye una importante ayuda diagnóstica en la investigación inicial y seguimiento del carcinoma del tracto urinario. Iniciada por Sanders en 1864 y popularizada por Papanicolaou- Marshall en 1945, el métodod ha logrado una sesibilidad de hasta el 100 por ciento. En el presente estudio retrospectivo de 5 años evaluamos 65 pacientes que consultaron al Servicio de Urología del Hospital Israelita por macro o microhematuria, en los que la investigación inicial con citología urinaria,cistoscopias y estudios por imágenes indicaban un disgnóstico presuntivo de carcinoma de tracto urinario, que posteriormente fue confirmado o descartado mediante el estudio histológico. Se trata de demostrar la correlación existente entre los mismos. Se encontró una mayor frecuencia de casos entre los 60 a 70 años (33,94 por ciento), afectando más al sexo masculino (77 por ciento). El índice de sensibilidad de la citología fue del 77,7 por ciento), con un porcentaje de falsos positivos del 16 por ciento. En el 22,2 poe ciento de biopsias posistivas la citología había sido negativa, como lo es tambvién la investigación del tracto urinario superior, en los casos falsos positivos, por la posibilidad de encontrar tumor en dicha localización. Se pobserva que la sensibilidad de la citología aumenta de acuerdo con el grado de diferenciación celular hallado en el tumor, así como de su estadio

ABSTRACT

A total of 24 cases of metastatic bone tumours were encountered over the last 6 years. Majority of these lesions (70.8%) were found in the 4th to 6th decades of life with a slight male preponderance. The axial skeleton was involved in majority of the cases (62.5%), the spine being the commonest site of tumour metastasis. A large proportion of the metastatic bone tumours were adenocarcinomas (62.5%) and the lung was the commonest primary site followed by the breast and large intestine. In 41.7% of the patients the bone metastasis was the initial manifestation of the malignant disease which was subsequently detected after investigations. In 20.8% of the cases the primary tumour remained undetected even after through investigations.

ABSTRACT

El tumor adenomatoide es el más común de los tumores de los tejidos paratesticulares, especialmente del epidídimo y túnicas testiculares, rara vez del cordón espermático; siendo su diámetro usual de 0.5 cm. El presente es el reporte de un caso de un varón de 30 años quien presentó retención urinaria por compresión de una masa pélvica gigante, lateralizada a la izquierda y que comprimía la vejiga. El urograma excretor y la ecografía localizaron el tumor retroperitonealmente. En la laparatomía se encontró una masa ovoide de aproximadamente 14 cm. de diámetro mayor, de pared blanquesina lisa, renitente, con áreas sólidas que comprimía sigmoide, grandes vasos y desplazaba la vejiga a la derecha. La anatomía patológica correspondio a tumor adenomatoide variedad angiomatoide. Se presenta el caso a propósito de su gran tamaño, su particular localización y lo infrecuente de esta patología.
