RESUMEN

RESUMEN Introducción: el cáncer de la vejiga es la segunda neoplasia urológica. En Cuba constituye la séptima causa de cáncer en el sexo masculino y entre las primeras quince, cuando se combinan ambos sexos. Objetivo: evaluar el comportamiento del cáncer de vejiga en pacientes del Hospital Universitario Comandante "Faustino Pérez Hernández". Materiales y Métodos: se realizó un estudio observacional, descriptivo y transversal en el período comprendido desde diciembre de 2014 hasta enero de 2020. Los pacientes se dividieron en tres grupos tratados con cirugía de mínimo acceso, cirugía abierta y no operados, se describieron los grupos histológicos y estadiaje tumoral y se les aplicó tratamiento según protocolo del servicio, sus complicaciones y la presencia de recidivas tumorales también fueron descritas. En el universo se incluyeron en el estudio 222 pacientes diagnosticados de cáncer de vejiga. Resultados: se comprobó que el mayor número de pacientes diagnosticados con cáncer de vejiga son del sexo masculino, el tipo histológico es el carcinoma de células uroteliales de bajo grado y el estadio T1. Las recidivas se presentaron antes de los 5 años en el 10,8% de los casos. 196 pacientes presentaron complicaciones. Conclusiones: el cáncer de vejiga es más frecuente en las edades comprendidas entre 60 a 69 años, las recidivas aparecieron mayormente entre 1 y 3 años. Se presentó complicaciones en 196 pacientes, siendo la cirugía la modalidad terapéutica que mayor por ciento tuvo con un 32.22% y las infecciones son las complicaciones más frecuentes (AU).


SUMMARY Introduction: Cancer of the bladder (CV) is the second urological neoplasm. In Cuba it constitutes the seventh cause of cancer in males and among the first fifteen, when both sexes are combined. Objective: To evaluate the behavior of bladder cancer (CV) in patients of the Faustino Pérez Hernández Hospital. Materials and methods: An observational, descriptive and cross-sectional study was carried out in the period from December 2014 to January 2020. The patients were divided into 3 groups treated with Minimum Access Surgery (CMA), Open Surgery (CA) and No Operated (NO), the histological groups and tumor staging were described and treatment was applied according to the service protocol, their complications and the presence of tumor recurrences were also described.Universe: 222 patients diagnosed with bladder cancer were included in the study. Results: It was found that the greatest number of patients diagnosed with CV are male, the histological type is low-grade urothelial cell carcinoma and stage T1. Recurrences occurred before 5 years in 10.8% of cases. 196 patients presented complications. Conclusions: The CV is more frequent in the ages between 60 to 69 years, the recurrences appeared mainly between 1 and three years. Complications occurred in 196 patients, with Surgery being the therapeutic modality with the highest percentage with 32.22% and infections being the most frequent complications (AU).

RESUMEN

Primary paraganglioma and small cell neuroendocrine carcinoma of the urinary bladder are rare tumors, comprising 0.05% of all bladder tumors and <1% of all malignant bladder tumors, respectively. These tumors can be the cause of a diagnostic dilemma or misdiagnosis on morphology. Paraganglioma is often mistaken for urothelial carcinoma and small cell carcinoma for poorly differentiated carcinoma or lymphoma. Herein, we report a case of primary paraganglioma and another of a small cell carcinoma of the urinary bladder and discuss their closest differential diagnoses. The diagnostic pitfalls should be kept in mind so that correct, timely diagnosis of these entities can be made due to implications in the management and prognosis.

RESUMEN

ABSTRACT Purpose The present study aimed to determine whether sarcopenia after radical cystectomy (RC) could predict overall survival (OS) in patients with urothelial bladder cancer (UBC). Materials and Methods The lumbar skeletal muscle index (SMI) of 80 patients was measured before and 1 year after RC. The prognostic significance of sarcopenia and SMI decrease after RC were evaluated using Kaplan-Meier analysis and a multivariable Cox regression model. Results Of 80 patients, 26 (32.5%) experienced sarcopenia before RC, whereas 40 (50.0%) experienced sarcopenia after RC. The median SMI change was -2.2 cm2/m2. Patients with sarcopenia after RC had a higher pathological T stage and tumor grade than patients without sarcopenia. Furthermore, the overall mortality rate was significantly higher in patients with sarcopenia than in those without sarcopenia 1 year after RC. The median follow-up time was 46.2 months, during which 22 patients died. Kaplan-Meier estimates showed a significant difference in OS rates based on sarcopenia (P=0.012) and SMI decrease (P=0.025). Multivariable Cox regression analysis showed that SMI decrease (≥2.2 cm2/m2) was an independent predictor of OS (hazard ratio: 2.68, confidence interval: 1.007-7.719, P = 0.048). Conclusions The decrease in SMI after surgery might be a negative prognostic factor for OS in patients who underwent RC to treat UBC.

RESUMEN

ABSTRACT Purpose To investigate the incidence and pathologic characteristics of prostate cancer (PCa) incidentally discovered at the time of radical cystectomy and its impact on overall survival. Materials and Methods A single center retrospective study of 762 male patients who underwent radical cystoprostatectomy from Jan 1994 to Dec 2012. Results Of all included patients, 132 (17.3%) were found to have PCa. Patients with incidental PCa had a significantly higher mean age (69.2 vs. 62.2 years, P=0.015). Among the 132 patients with PCa, prostate specific antigen (PSA) analysis was available in 76 patients (57.6%), with a median value of 1.06ng/mL, and 61 (80.3%) patients had a PSA value below 4ng/mL. Four hundred and thirty-six patients (57.1%) were successfully followed, with a median duration of 46.5 months. The overall 5-year survival rate was 62.1%, and the 5-year cancer-specific survival rate was 72%. PCa recurrence was defined by two consecutive PSA values of >0.2 ng/mL and rising, and no PCa recurrence occurred. According to a univariate analyses, incidental PCa was not associated with cancer-specific survival (P=0.192) or overall survival (P=0.493). According to univariate analyses, the overall survival of patients with PCa was not associated with prostate cancer staging, PSA value, or Gleason score (All P values>0.05). Conclusions Prostate cancer incidentally discovered at the time of radical cystectomy does not decrease overall survival. Patients with incidental PCa were older than those without. The PSA value before operation is not helpful for predicting incidental prostate cancers.

RESUMEN

ABSTRACT Introduction and Objective Radical cystectomy (RC) with pelvic lymph node dissection is the standard treatment for muscle invasive bladder cancer and the oncologic outcomes following it are directly related to disease pathology and surgical technique. Therefore, we sought to analyze these features in a cohort from a Brazilian tertiary oncologic center and try to identify those who could negatively impact on the disease control. Patients and Methods We identified 128 patients submitted to radical cystectomy, for bladder cancer treatment, from January 2009 to July 2012 in one oncology tertiary referral public center (Mario Penna Institute, Belo Horizonte, Brazil). We retrospectively analyzed the findings obtained from their pathologic report and assessed the complications within 30 days of surgery. Results We showed similar pathologic and surgical findings compared to other large series from the literature, however our patients presented with a slightly higher rate of pT4 disease. Positive surgical margins were found in 2/128 patients (1.5%). The medium number of lymph nodes dissected were 15. Major complications (Clavien 3 to 5) within 30 days of cystectomy occurred in 33/128 (25.7%) patients. Conclusions In the management of invasive bladder cancer, efforts should focus on proper disease diagnosis and staging, and, thereafter, correct treatment based on pathologic findings. Furthermore, extended LND should be performed in all patients with RC indication. A critical analysis of our complications in a future study will help us to identify and modify some of the factors associated with surgical morbidity.

RESUMEN

CONTEXT: Pheochromocytoma is a catecholamine-producing tumor characterized by hypertension, headache, tachycardia, excessive diaphoresis and angina. The thunderclap headache is so named because the pain strikes suddenly and severely. Although the symptoms of bladder pheochromocytoma are rather evident, the diagnosis of this rare neuroendocrine tumor can be missed. CASE REPORT: This study reports the case of a woman diagnosed with bladder pheochromocytoma who experienced thunderclap headache triggered by micturition and angina as an initial manifestation. CONCLUSION: This case study suggests that thunderclap headache and angina occurring concurrently with sudden blood pressure elevation during or immediately after micturition are important diagnostic clues for bladder pheochromocytoma. .


CONTEXTO: Feocromocitoma é um tumor produtor de catecolaminas, caracterizado por hipertensão, cefaleia, taquicardia, sudorese excessiva e angina. A dor de cabeça trovão é assim chamada porque a dor ataca de repente e intensamente. Embora os sintomas de feocromocitoma de bexiga sejam bastante evidentes, o diagnóstico deste tumor neuroendócrino raro pode ser perdido. RELATO DE CASO: Este estudo relata o caso de uma mulher diagnosticada com feocromocitoma na bexiga que sentiu a dor de cabeça trovão, desencadeada pela micção e angina como manifestação inicial. CONCLUSÃO: Este estudo de caso sugere que a dor de cabeça trovão e angina ocorrendo simultaneamente com a elevação da pressão de sangue repentina durante ou imediatamente após a micção são dicas importantes de diagnósticos de feocromocitoma na bexiga. .

RESUMEN

El carcinoma neuroendocrino primario de vejiga es una neoplasia infrecuente que representa el 0,5por ciento de todos los tumores vesicales. La asociación de carcinoma neuroendocrino de vejiga en un paciente con infección por VIH nunca hasta hoy había sido descrita. Presentamos el primer caso clínico español y mundial de esta desconocida y nunca descrita asociación. MATERIAL Y MÉTODOS: Se presenta el caso clínico de una paciente de 46 años con infección por VIH que desarrolló un carcinoma neuroendocrino de vejiga urinaria de evolución fatal. Se describe su clínica de presentación, métodos de diagnóstico utilizados y su tratamiento. La paciente debutó con retención urinaria aguda que rápidamente progresó a la instauración de una uropatía obstructiva alta con deterioro de la función renal. El diagnóstico se efectuó mediante TAC, resección transuretral y estudio histopatológico donde la clave del diagnóstico fue el estudio inmunohistoquímico intensamente positivo para la cromogranina A. El tratamiento adyuvante con quimioterapia le ocasionó una aplasia medular severa, falleciendo por fallo multiórganico a los 26 días de su diagnóstico. A propósito de este caso, se revisa la literatura inglesa en PubMed sobre carcinoma neuroendocrino de vejiga y sobre tumores vesicales en pacientes con infección VIH, no existiendo ningún caso publicado de carcinoma neuroendocrino de vejiga en un paciente con infección por VIH. CONCLUSIONES: El carcinoma neuroendocrino de vejiga es un tumor infrecuente y muy agresivo. Es un tumor que suele presentarse clínicamente en estadios avanzados o metastásicos donde ninguna terapia es eficaz. El tratamiento incluye resección trans-uretral (RTU), cistectomía parcial, cistectomía radical y quimioterapia. El estudio inmunohistoquímico (IHQ) y la tinción con cromogranina A dan la clave para su diagnóstico. Su presentación en pacientes VIH implica muy mal pronóstico. Éste caso es el primer caso mundial publicado de carcinoma neuroendocrino...


The primary neuroendocrine carcinome of the bladder is an infrequent neoplasm which represents 0.5 percent of all vesical tumors. The association of neuroendocrine carcinome of the bladder in a patient with HIV infection has never been described before today. We present the first clinical case in the Spanish-speaking world and worldwide, of this unknown and never written about association. MATERIAL AND METHODS: The clinical case of a 46-yearoldpatient with HIV infection who developed a neuroendocrine carcinoma of the urinary bladder with a fatal evolution, its clinical presentation, the diagnosis methods used and its treatment, are described. The patient started with a severe urinary retention which rapidly progressed to the establishment of a high obstructive uropathy with deterioration in the renal function. The diagnosis was done using TAC, transurethral resection and histopathological study where the key to diagnosis was the intensely positive immunohistochemical study for the chromogranin A. The adjuvant treatment with chemotherapy led to a severe medular aplasia, with the patient dying due to a multi-organ failure, 26 days after her diagnosis. As a result of this case, English literature on the matter in PubMed about neuroendocrine carcinome of the bladder and about vesical tumors in patients with HIV infection was revised, with no published case existing about neuroendocrine carcinome in a patient with HIV. CONCLUSIONS: The neuroendocrine carcinome of the bladder is an infrequent and very aggressive tumor. It is a tumor that tends to be clinically present in advanced or metastasic states, where no therapy is efficient. The treatment includes transurethral resection (TUR), partial cystectomy, radical cystectomy and chemotherapy. The immunohistochemical study (IHC), and the stain with chromogranin A are key for its diagnosis. Its presentation in HIV patients implies a very bad prognosis. This case is the first published case worldwide of neuroendocrine...

RESUMEN

PURPOSE: Inflammation-based prognostic scores including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) are associated with oncologic outcomes in diverse malignancies. We evaluated the predictive value of pretreatment prognostic scores in differentiating nonmuscle invasive (NMIBC) and muscle invasive bladder cancer (MIBC). MATERIALS AND METHODS: Consecutive transurethral resection of bladder tumour (TURBT) cases from January 2011 to December 2013 were analysed retrospectively. Patient demographics, tumour characteristics and prognostic scores results were recorded. Receiver operating characteristics curves were used to determine prognostic score cutoffs. Univariate and multivariate binomial logistic regression analysis was performed to evaluate the association between variables and MIBC. RESULTS: A total of 226 patients were included, with 175 and 51 having NMIBC (stages Ta and T1) and MIBC (stage T2+) groups, respectively. Median age was 75 years and 174 patients were male. The NLR cutoff was 3.89 and had the greatest area under the curve (AUC) of 0.710, followed by LMR (cutoff218; AUC, 0.642). Full blood count samples were taken a median of 12 days prior to TURBT surgery. Multivariate logistic regression analysis identified tumour grade G3 (odds ration [OR], 32.848; 95% confidence interval [CI], 9.818-109.902; p=0.000), tumour size> or =3 cm (OR, 3.353; 95% CI, 1.347-8.345; p=0.009) and NLR> or =3.89 (OR, 8.244; 95% CI, 2.488-27.316; p=0.001) as independent predictors of MIBC. CONCLUSIONS: NLR may provide a simple, cost-effective and easily measured marker for MIBC. It can be performed at the time of diagnostic flexible cystoscopy, thereby assisting in the planning of further treatment.

RESUMEN

O câncer de bexiga é um importante problema de saúde mundial, tanto pelas elevadas taxas de prevalência, quanto pelos custos relacionados ao tratamento. Desde a introdução da imunoterapia intravesical adjuvante com bacilo Calmette-Guérin, vem sendo observada diminuição na taxa de recorrência. As principais complicações são de pequeno porte e simples resolução a partir de medidas locais e orientações. A bexiga contraída, uma complicação local rara e grave, mas incapacitante em alguns casos, é observada principalmente em doentes com um programa de manutenção. Relatamos aqui o caso de um paciente masculino submetido a ressecção transuretral da bexiga por um carcinoma urotelial T1 de alto grau, que desenvolveu tal complicação durante tratamento com bacilo Calmette-Guérin, sendo portanto submetido à cistoprostatectomia com realização de neobexiga ortotópica ileal.


Bladder cancer is an important health problem worldwide due to high prevalence rates and costs related to treatment. A reduction in recurrence rates has been observed since the introduction of adjuvant intravesical immunotherapy with bacillus Calmette-Guerin. There are mild complications that are easily solved by local measures and orientations. Bladder contracture, a rare and severe local complication, in some cases leading to disability, is observed primarily in patients in a maintenance program. In this article we reported the case of a male patient who underwent transurethral resection of the bladder because of a high-grade T1 urothelial carcinoma and developed this complication during treatment with bacillus Calmette-Guerin. For this reason he was submitted to cystoprostatectomy with orthotopic ileal neobladder reconstruction.

RESUMEN

Vesicoenteric fistula is a rare complication of bladder squamous cell carcinoma. We report the case of a 70-year-old male who complained of painless, total gross hematuria. Abdominopelvic computed tomography (CT) revealed an approximately 2.7-cm lobulated and contoured enhancing mass in the bladder dome. We performed partial cystectomy of the bladder dome after transurethral resection of the bladder. The biopsy result was bladder squamous cell carcinoma, with infiltrating serosa histopathologically, but the resection margin was free. Postoperatively, follow-up CT was done after 3 months. Follow-up CT revealed an approximately 4.7-cmx4.0-cm lobulated, contoured, and heterogeneous mass in the bladder dome. A vesicoenteric fistula was visible by cystography. Here we report this case of a vesicoenteric fistula due to bladder squamous cell carcinoma.

RESUMEN

It has not yet been determined whether chronic exposure to relatively low doses of pioglitazone increases risk of bladder cancer. We aimed to assess the risk of bladder cancer associated with pioglitazone in Korean patients. This was a retrospective cohort study of diabetic patients who had > or = 2 clinic visits between November 2005 and June 2011 at one of four tertiary referral hospitals in Korea. A prevalent case-control analysis nested within the cohort was conducted to further adjust confounders. A total of 101,953 control patients and 11,240 pioglitazone-treated patients were included, in which there were 237 and 30 cases of incidental bladder cancer (64.9 and 54.9 per 100,000 person-years; age, sex-adjusted HR 1.135, 95% confidence interval [CI] 0.769-1.677), respectively. In the prevalent case-control analysis nested within the cohort, use of pioglitazone for a duration of > 6 months, but not ever use of pioglitazone, was associated with an increased rate of bladder cancer as compared to never use of pioglitazone. In conclusion, we failed to exclude the possible association between use of pioglitazone for a duration of > 6 months and bladder cancer.

RESUMEN

Objective The aim of our study was to assess short and mid-term clinical efficacy of external beam radiation therapy to achieve hemostasis in patients with bladder-cancer related gross hematuria who were unfit for surgery. We also assessed hypofractionation as a possible alternative option for more severe patients. Patients and Methods Thirty-two patients were included for hemostatic radiation therapy, with two schedules based on Eastern Cooperative Oncology Group performance status. The standard treatment was 30 Gy in 10 fractions over 2 weeks. More severe patients underwent a hypofractionated regimen, with 20 Gy in 5 fractions over a one week period. Clinical evaluation was performed at 2 weeks and 6 months. Results At 2 weeks, 69% of patients were hematuria-free. Subgroup analysis showed that 79% of patients undergoing hypofractionated regimen were hematuria-free. A total of 54% were hematuria-free with the standard regimen. Based on tumor stage, hematuria was controlled at 2 weeks for 57% of non-muscle invasive tumors and 72% of muscle-invasive tumors. After 6 months, 69% of patients had relapsed, regardless of tumor stage or therapy schedules. Conclusions Hemostatic radiotherapy is an effective option for palliative-care hematuria related to bladder cancer in patients unfit for surgery. Although it appears to be rapidly effective, its effect is of limited duration. Hypofractionation also seems to be an effective option; however larger cohorts and prospective trials are needed to evaluate its efficacy compared to standard schedules. .

RESUMEN

Pheochromocytoma is a tumor of aderenal medulla which secrets catecholamines and usually presents as hypertension. Extra-adrenal pheochromocytomas are extremely rare. They occur in the organ of zukerkundle, bladder, retroperitonium, posterior mediastinum and sympathetic chain. We present a case of a young male who presented with hypertension and eventually was found to have extra adrenal pheochromocytoma of the bladder.

RESUMEN

Superior vena cava [SVC] syndrome is caused by compression or obstruction of the SVC. We report here in a case of SVC syndrome due to lymph node metastasis from urothelial cancer to the mediastinum and lung. The origin of metastasis was determined by computed tomography [CT]-guided biopsy of metastases. After radiotherapy to the mediastinum with glucocorticoid failed, anticancer pharmacotherapy including paclitaxel, gemicitabine, and cisplatin proved effective and SVC syndrome resolved. But patient died from cerebral bleeding from newer brain metastases 10 months later

RESUMEN

A bladder infection of Aspergillus with no evidence of dissemination is rare. We present a case of Aspergillus infection with transitional cell carcinoma of the urinary bladder without any evidence of systemic involvement. A 65-year-old male diabetic whose main complaints were intermittent painful haematuria and nocturia had undergone nephroureterectomy a year and a half back for transitional cell carcinoma of right renal pelvis. Cystoscopy revealed bladder mucosa having fixed broad tumour with encrustation and bleeding on touch at the right vesico-ureteric junction. The histopathologic diagnosis was a high-grade transitional carcinoma with Aspergillus infection. Fungal culture of urine obtained after bladder wash yielded Aspergillus fumigatus.
