ABSTRACT

PURPOSE: Surgical excision of the primary tumor in penile cancer (PC) has shown good local control with a risk of locoregional recurrence (LR) of 4-8%. The magnitude of such risk and the characteristics that distinguish patients who develop LR from those who do not is controversial. Our goal was to estimate, clinical and oncological characteristics, and outcome of LR in a cohort of patients with PC. MATERIALS AND METHODS: A retrospective, case-control study of ten patients with LR of PC and ten controls. Using a multivariate analysis for clinical and oncological characteristics was evaluated to determine their association with LR. RESULTS: Cases and controls were similar in regards to the prevalence of diabetes, age, grade of differentiation, presence of lymphovascular invasion (LVI), and positive margins. In our multiple logistic regression analysis clinical stage (CS), LVI and positive margins were associated with LR. Time to LR had a median of 15 months. CONCLUSIONS: Our study confirms that patients with advanced CS, LVI and positive margins after surgical excision of the primary tumor could have higher risk of LR. We believe that a close oncological follow-up should be done in patients with adverse oncological characteristics.


OBJETIVO: La escisión quirúrgica del tumor primario en cáncer de pene (PC) ha demostrado un buen control local con un riesgo de recurrencia locorregional (LR) del 4-8%. La magnitud del riesgo y las características que distinguen a los pacientes con recurrencia locorregional de los que no la presentan son motivo de controversia. Nuestro objetivo fue analizar características clínicas y oncológicas para establecer su relación LR en una cohorte de pacientes con PC. MATERIAL Y MÉTODOS: Estudio retrospectivo de casos y controles de 10 pacientes con LR de PC y 10 controles. Mediante un análisis multivariado se analizaron características clínicas y oncológicas y se determinó su asociación con LR. RESULTADOS: Los casos y controles fueron similares en cuanto a prevalencia de diabetes, edad, grado de diferenciación, invasión linfovascular y márgenes positivos. En nuestro análisis de regresión logística múltiple, el estadio clínico (CS), la invasión linfovascular y los márgenes positivos se asociaron con LR. El tiempo a la LR tuvo una mediana de 15 meses. CONCLUSIONES: Nuestro estudio confirma que los pacientes con CS avanzado, invasión linfovascular y márgenes positivos podrían tener mayor riesgo de LR. Creemos que debe realizarse un seguimiento oncológico estrecho en pacientes con características oncológicas adversas.

ABSTRACT

BACKGROUND: Urachal cancer is one of the rarest and aggressive malignant diseases of the bladder; its incidence was 0.2% of all bladder cancers in 2012. It occurs in advanced stages, among stage IV tumors 58% die at 22 months. It is originated from urachal, an embryological structure that is present in 32% of the adult population. OBJECTIVE: To present a case series of urachal cancer in a third level medical facility. METHOD: Case series. Clinical data from patients with of urachal cancer during 2011 to 2019 were analyzed. The variables included were age, gender, smoking, clinical stage, treatment and evolution. Descriptive statistics, measures of central tendency and dispersion were used. RESULTS: There were seven patients; three men and four women; the mean age was 54.4 years. The most frequent histological type was mucinous adenocarcinoma. Partial cystectomy was performed with bilateral pelvic lymphadenectomy in three (42.8%) patients, radical cystectomy plus bilateral pelvic lymphadenectomy in the remaining four (57.2% patients). CONCLUSIONS: Urachal cancer is rare, clinical manifestations occur late. Hematuria is the most frequent clinical sign. The medium term prognosis is bad.


ANTECEDENTES: El cáncer de uraco es una de las enfermedades malignas de la vejiga más raras y agresivas. Su incidencia en 2012 era del 0.2% de todos los cánceres de vejiga. Se presenta en estadios avanzados, con una mortalidad del 58% a 22 meses para el estadio IV. Se origina a partir del uraco, una estructura embriológica que está presente en el 32% de la población adulta. OBJETIVO: Presentar las características clínicas de una serie de casos de cáncer de uraco en una unidad de tercer nivel de atención médica. MÉTODO: Serie de casos. Se analizaron los resultados clínicos obtenidos de pacientes con cáncer de uraco de 2011 a 2019. Las variables incluidas fueron edad, sexo, tabaquismo, estadio clínico, tratamiento y evolución. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión. RESULTADOS: Fueron siete pacientes, tres hombres y cuatro mujeres, con una edad media de 54.4 años. El tipo histológico más frecuente fue adenocarcinoma tipo mucinoso. Se realizó cistectomía parcial con linfadenectomía pélvica bilateral a tres pacientes (42.8%), y cistectomía radical más linfadenectomía pélvica bilateral en los otros cuatro (57.2%). CONCLUSIONES: El cáncer de uraco es una enfermedad rara. Sus manifestaciones son tardías y el signo clínico principal es la hematuria. El pronóstico es malo a mediano plazo.

ABSTRACT

ANTECEDENTES: El carcinoma renal con diferenciación sarcomatoide confiere un pronóstico sombrío por su evolución metastásica; a mucosa oral corresponde menos del 1%. CASO CLÍNICO: Mujer de 66 años, tumor dependiente de riñón izquierdo con reporte de patología de carcinoma renal de células claras patrón sarcomatoide, tumor gingival en maxilar izquierdo, biopsia con metástasis de células claras sarcomatoide. Recibió radioterapia local. Progresó con metástasis a sistema nervioso central, pulmonar, mediastinal y suprarrenal. CONCLUSIONES: La presentación clínica de tumores renales en la mucosa oral es rara. La presencia de diferenciación sarcomatoide implica un reto terapéutico por la respuesta a las terapias sistémicas existentes. Los avances en fármacos con actividad inmunitaria podrían mejorar las tasas de respuesta. BACKGROUND: The renal carcinoma with sarcomatoid differentiation confers a poor prognosis due to its metastatic evolution, less than 1% corresponds to oral mucosa. CASE REPORT: 66 year old female, left kidney tumor, with pathology report clear cell renal carcinoma, with sarcomatoid pattern, gingival tumor in the left maxilla, biopsy with sarcomatoid metastases, received local radiotherapy. It progressed with metastases to the central nervous system, pulmonary, mediastinal and adrenal. ­. CONCLUSIONS: The clinical presentation of kidney tumors in oral mucosa is rare, the presence of sarcomatoid differentiation implies a therapeutic challenge due to the response to existing systemic therapies, advances in drugs with immunological activity could improve response rates.

ABSTRACT

Introducción: El carcinoma de células renales representa el 2-3% de todos los cánceres. Alrededor del 30% de los pacientes presentan metástasis en el momento del diagnóstico y otro 30% de los pacientes con enfermedad localizada desarrollan recurrencia o metástasis. El sitio más común de metástasis es el pulmón, el hueso y el hígado. Objetivo: presentar una paciente con metástasis ocular como una presentación atípica de carcinoma de células renales. Caso clínico: Femenino de 41 años, tres meses previos inició con dolor ocular urente, fotopsias, hemianopsias y disminución de la agudeza visual del ojo derecho. La exploración física dirigida mostró tumor subretiniano. Se le realizó enucleación del ojo afectado y colocación de implante, con hallazgo de tumor intracelar y reporte histopatológico de carcinoma de células claras. Los estudios de extensión mostraron tumor renal izquierdo. Se le realizó nefrectomía radical izquierda con adrenalectomía derecha en un mismo tiempo quirúrgico. Discusión: El carcinoma de células renales metastásico tiene un pronóstico malo, la sobrevida al año es de 48% y a los 5 años de 9%. La metástasis única al momento del diagnóstico tiene pronóstico mejor que las múltijples. Conclusiones; El CCR puede metastatizar a sitios raros como el globo ocular entre otros (AU)


Introduction: Renal cell carcinoma accounts for 2-3% of all cancers. About 30% of patients have metastases at the time of diagnosis, other 30% with the patients with localized disease develop recurrence or metastasis. The most common site of metastasis are lungs, bones and liver. Objetive: to present a patient with ocular metastasis as an atypical presentation of renal cell carcinoma. Clinical case: Forty one years old female, three months before, began with burning eye pain, photopsies, hemianopsies and decreased visual acuity of the right eye. The directed physical examination showed subretinal tumor. Enucleation of the afected eye and implant placement was performed, with intracelar tumor finding and histopathological report of clear cell carcinoma. The extension studies showed left renal tumor. Left radical nephrectomy was performed with right adrenalectomy in the same surgical time. Discussion: Metastatic renal cell carcinoma has a poor prognosis, the survival rate is 48% at 5 years and 9% at 5 years. The single metastasis at the time of diagnosis has a better prognosis than multiple ones. Conclusions: RCC can metastasize to rare sites such as the eyeball among others (AU)

ABSTRACT

PURPOSE: To determine the effectiveness of intralesional administration of onabotulinumtoxinA in patients with Peyronie's disease (PD). MATERIALS AND METHODS: A prospective therapeutic cohort study was undertaken in patients aged ≥ 18 years with stable PD. Intervention included one-time intralesional application of 100 U of onabotulinumtoxinA. We included 22 patients who attended the urology clinic from October 1, 2011 to June 30, 2012. Primary outcome measure was degree of curvature. Secondary outcome measures were thickness of the fibrous plaque, improvement in erectile function and pain. Erectile function was evaluated using the International Index of Erectile Function (IIEF-5) questionnaire. The Visual Analog Scale (VAS) was used to measure pain during an erection. Statistical analyses were performed by Pearson's chi-squared test for categorical variables and student's t-test for quantitative variables. Any P value < .05 was considered statistically significant. RESULTS: The size of the fibrous plaque was reduced from 0.34 ± 0.20 to 0.27 ± 0.13 cm after treatment (P = .014). The curvature initially averaged 32.95 ± 9.21°, and improved to 25 ± 9.38° (P = .025). According to the Kelami classification, the curvature was < 30° in 14 cases (63.6%) and was 30°-60° in eight cases (36.4%). At 16 weeks, the curvature was < 30° in 19 cases (86.4%) and 30°-60° in three cases (13.6%). The IIEF-5 score was 16.18 ± 4.46 before treatment and 18.22 ± 4.55 after treatment (P = .002). Pain was reduced from 3.36 ± 3.48 before treatment to 1.14 ± 1.58 after treatment (P = .001). CONCLUSION: The administration of onabotulinumtoxinA may improve the clinical manifestations of PD resulting from fibrosis, thus improving sexual function in patients.
