ABSTRACT
Fundamento: El cáncer primario de uretra se define como el tumor cuya primera lesión se localiza en la uretra; es infrecuente, el mismo representa menos del 1 % de los tumores malignos y el 5 % de los tumores malignos del sistema urinario. La extensión de este proceso a la glándula prostática genera sintomatología urinaria obstructiva e irritativa y cuadros agudos como la hematuria macroscópica. Objetivo: Presentar el caso de un paciente con cáncer primario de uretra en su variedad urotelial con hematuria macroscópica como forma clínica de presentación. Presentación del caso: Caso clínico de un paciente masculino de 75 años de edad, con hematuria macroscópica como forma clínica de presentación de cáncer primario de uretra en su variedad urotelial, el cual se diagnosticó anatomopatológicamente durante el estudio de la hematuria. Conclusiones: El caso que se presenta permite alertar a la comunidad científica que en pacientes que presentan hematuria macroscópica, sin manifestaciones urológicas obstructivas ni irritativas, también debe tenerse en cuenta el diagnóstico de cáncer uretral primario, aunque sea un signo infrecuente como forma clínica de presentación de esa enfermedad.
Background: Primary urethral cancer is defined as a tumor whose first lesion is located in the urethra; is very uncommon, represents less than 1% of malignant tumors and 5% of malignant tumors of the urinary system. The extension of this process to the prostate gland creates obstructive and irritative urinary symptoms and acute conditions such as macroscopic hematuria. Objective: To present the case of a patient with primary urethral carcinoma in its urothelial variety with macroscopic hematuria as clinical presentation. Case presentation: Clinical case of a 75-year-old male patient, with macroscopic hematuria as a clinical presentation of primary cancer of the urethra in its urothelial variety, diagnosed anatomopathologically during the hematuria study. Conclusions: The case presented alerts the scientific community that the diagnosis of primary urethral cancer should be considered in patients with macroscopic hematuria in the absence of obstructive or irritative urologic manifestations, although it is a rare sign as clinical presentation of this disease.

Inflammatory bowel disease (IBD) is a chronic condition that affects the digestive tract and can lead to inflammation and damage to the intestinal lining. IBD patients with cancer encounter difficulties since cancer treatment weakens their immune systems. A multidisciplinary strategy that strikes a balance between the requirement to manage IBD symptoms and the potential effects of treatment on cancer is necessary for effective care of IBD in cancer patients. To reduce inflammation and avoid problems, IBD in cancer patients is often managed by closely monitoring IBD symptoms in conjunction with the necessary medication and surgical intervention. Anti-inflammatory medications, immunomodulators, and biologic therapies may be used for medical care, and surgical options may include resection of the diseased intestine or removal of the entire colon. The current study provides a paradigm for shared decision-making involving the patient, gastroenterologist, and oncologist while considering recent findings on the safety of IBD medicines, cancer, and recurrent cancer risk in individuals with IBD. We hope to summarize the pertinent research in this review and offer useful advice. (AU)

Objective: To explore the application of manual screening collaborated with the Artificial Intelligence TPS-Assisted Cytologic Screening System in urinary exfoliative cytology and its clinical values. Methods: A total of 3 033 urine exfoliated cytology samples were collected at the Henan People's Hospital, Capital Medical University, Beijing, China. Liquid-based thin-layer cytology was prepared. The slides were manually read under the microscope and digitally presented using a scanner. The intelligent identification and analysis were carried out using an artificial intelligence TPS assisted screening system. The Paris Report Classification System of Urinary Exfoliated Cytology 2022 was used as the evaluation standard. Atypical urothelial cells and even higher grade lesions were considered as positive when evaluating the recognition sensitivity, specificity, and diagnostic accuracy of artificial intelligence-assisted screening systems and human-machine collaborative cytologic screening methods in urine exfoliative cytology. Among the collected cases, there were also 1 100 pathological tissue controls. Results: The accuracy, sensitivity and specificity of the AI-assisted cytologic screening system were 77.18%, 90.79% and 69.49%; those of human-machine coordination method were 92.89%, 99.63% and 89.09%, respectively. Compared with the histopathological results, the accuracy, sensitivity and specificity of manual reading were 79.82%, 74.20% and 95.80%, respectively, while those of AI-assisted cytologic screening system were 93.45%, 93.73% and 92.66%, respectively. The accuracy, sensitivity and specificity of human-machine coordination method were 95.36%, 95.21% and 95.80%, respectively. Both cytological and histological controls showed that human-machine coordination review method had higher diagnostic accuracy and sensitivity, and lower false negative rates. Conclusions: The artificial intelligence TPS assisted cytologic screening system has achieved acceptable accuracy in urine exfoliation cytologic screening. The combination of manual screening and artificial intelligence TPS assisted screening system can effectively improve the sensitivity and accuracy of cytologic screening and reduce the risk of misdiagnosis.

Introduction It is known that cancer care is best approached by a multidisciplinary team (MDT). This became specifically true in the Covid-19 pandemic in which choices for urological cancer treatment are influenced by many factors. In some cases, delayed treatment may have consequences regarding the patient's oncological outcomes. The aim of the present article is to report our experience throughout the Covid-19 pandemic treating patients with urological neoplasms at a high-volume center. Methods We used a convenience sampling method. Cases were evaluated and discussed on an individual basis at the MDT meetings, and, after a consensus regarding delaying or scheduling treatment, patients were scheduled according to the risk of postponing the procedures. The Medically Necessary, Time-Sensitive (MeNTS) scoring system was measured in each patient; all patients answered the Centers for Disease Control and Prevention (CDC) Covid-19 self-screening questionnaire prior to surgery. The Covid-19-free survival rate was estimated. Results A total of 194 patients were assessed by themultidisciplinary team and finally treated, with median follow-up of 4 (interquartile range [IQR]: 2.75 to 6) months. Only two patients had Covid-19 confirmed by real-time polymerase chain reaction (RT-PCR). In total, 54 patients underwent oncological surgery, 129 were treated with radiotherapy, and 11 were treated with intravenous chemotherapy. Themedian age was 66 years (IQR: 59 to 94 years), and the median MeNTS score in the surgically-treated cohort was 35 points (IQR: 31 to 47 points). Conclusions The evaluation and treatment of urological cancer should be conducted by an MDT; this is of utmost importance, especially during the Covid-19 pandemic. The data collected in our institution showed that most patients could be safely treated by taking all necessary precautions and discussing each case individually in the MDT meetings and performing a close follow-up.
Introduccion La atencioÌn del caÌncer se aborda mejor con un equipo multidisciplinario (EMD), aspecto que se tornoÌ maÌs importante en la pandemia por Covid-19, en que las opciones para tratar el caÌncer uroloÌgico estaÌn influenciadas por muchos factores. En algunos casos, el tratamiento retrasado puede tener consecuencias en los resultados oncoloÌgicos del paciente. El objetivo de este estudio es describir nuestra experiencia en un centro de referencia y de alto volumen para el tratamiento de neoplasias urológicas durante la pandemia por Covid-19. MeÌtodos Realizamos un muestreo por conveniencia. Posteriormente, los casos fueron evaluados y discutidos de forma individual en las reuniones del EMD. Posterior a la obtencioÌn de un consenso sobre el tratamiento del paciente, los pacientes fueron programados seguÌn el riesgo individual de posponer el manejo. Se midioÌ la puntuacioÌn de cada paciente en el sistema Medically Necessary Time-Sensitive (MeNTS, "Médicamente necesario, sensibles al tiempo"). Todos los pacientes respondieron el cuestionario de autoevaluacioÌn del Centers for Disease Control and Prevention (CDC) COVID-19 antes de la cirugiÌa. Se estimó la tasa de supervivencia libre de Covid-19. Resultados Un total de 194 pacientes fueron evaluados por el EMD y finalmente tratados, con una mediana de seguimiento de 4 (rango intercuartil [RIC]: 2,75 a 6) meses. Solo dos teniÌan Covid-19 confirmado por reacción en cadena de la polimerasa en tiempo real (RCP-TR). Un total de 54 pacientes fueron sometidos a cirugiÌa oncoloÌgica, 129 fueron tratados con radioterapia, y 11 fueron tratados con quimioterapia intravenosa. La mediana de edad fue de 66 anÌos (RIC: 59 a 94 años), la puntuacioÌn mediana en el MeNTS de la cohorte tratada quiruÌrgicamente fue de 35 puntos (RIC: 31 a 47 puntos). Conclusiones La evaluacioÌn y el tratamiento del caÌncer uroloÌgico debe ser realizado por un EMD durante la pandemia de Covid-19. Los datos recopilados en nuestra institucioÌn mostraron que la mayoriÌa de los pacientes podriÌan ser tratados de manera segura, discutiendo cada caso individualmente y haciendo un seguimiento cercano.

RESUMEN Los tumores del tracto urinario superior representan menos del 5 % de todas las neoplasias uroteliales, con un porcentaje de recurrencia superior al 90 % y una supervivencia a los 5 años que oscila entre el 30-60 %. Por tales razones se presenta el caso de un paciente de 79 años que fue ingresado en el Hospital General Universitario Dr. Gustavo Aldereguía Lima de Cienfuegos, con un cuadro clínico caracterizado por hematuria, sin otra sintomatología. Mediante estudios imagenológicos le fue diagnosticado un tumor en la pelvis del riñón derecho. Se realizó tratamiento quirúrgico, practicándose una nefrectomía total, cuyo resultado histológico fue un carcinoma de células transicionales grado II con infiltración a planos musculares. La evolución clínica fue favorable luego de un año de la cirugía. Podemos concluir que en el diagnóstico precoz tienen un papel fundamental las imágenes tomográficas, pues permitieron identificar un tumor de las vías excretoras urinarias superiores en pelvis renal derecha. Se trazó una estrategia terapéutica inicialmente quirúrgica y a continuación quimioterapia; se logró una evolución satisfactoria y contribuir a la sobrevida de este paciente.
ABSTRACT Upper urinary tract tumors represent less than 5% of all urothelial neoplasms, with a recurrence rate greater than 90% and a 5-year survival that ranges from 30-60%. Therefore a 79-years-old patient was admitted to the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos, with a medical history characterized by hematuria, without other symptoms. Through imaging studies, he was diagnosed with a tumor in the pelvis of the right kidney. Surgical treatment was performed and a total nephrectomy was performed, the histological result of which was a grade II transitional cell carcinoma with infiltration to the muscular planes. The clinical evolution was favorable one year after surgery. We conclude that tomographic images play a fundamental role in early diagnosis, since they allowed the identification of a tumor of the upper urinary excretory tract in the right renal pelvis. A therapeutic strategy was initially designed for surgery and then chemotherapy; a satisfactory evolution was achieved and contributes to the survival of this patient.

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.

ABSTRACT Purpose: Epidemiological studies reported conflicting results about preoperative hydronephrosis in upper tract urothelial carcinoma (UTUC). This study aimed to investigate the association between preoperative hydronephrosis and pathologic features and oncologic outcomes in patients with UTUC treated by radical nephroureterectomy (RNU). Materials and Methods: This was a retrospective, single-center cohort study of 377 patients treated by RNU without perioperative chemotherapy between January 2001 and December 2014. Logistic regression, Cox regression, and survival analyses were performed. Results: Among the 226 patients with high-grade UTUC, 132 (58%) had preoperative hydronephrosis. Multivariable logistic regression revealed that hydronephrosis was independently associated with advanced pT stage (P=0.017) and lymph node or lymphovascular invasion (P=0.002). Median follow-up was 36 months (interquartile range: 20-48 months). The 3- and 5-year overall survival (OS) rates in patients with hydronephrosis were significantly lower than in those without hydronephrosis (both P <0.001). The 3- and 5-year cancer-specific survival (CSS) rates in patients with hydronephrosis were significantly lower than in those without hydronephrosis (both P=0.001). Hydronephrosis was independently associated with OS and CSS (P=0.001 and P=0.004, respectively). Among the 151 patients with low-grade UTUC, hydronephrosis was not associated with pathologic features and postoperative survival. Conclusions: Preoperative hydronephrosis was significantly associated with adverse pathologic features and postoperative survival in patients with high-grade UTUC.

OBJECTIVE@#To investigate the clinical characteristics, diagnosis and treatment of renal cell carcinoma with urinary tract tumor thrombus.@*METHODS@#From January 1, 2015 to December 31, 2019, patients with renal cell carcinoma complicated with urinary tract tumor thrombus who were hospitalized in the Peking University Third Hospital and Beijing Friendship Hospital, Capital Medical University were retrospectively analyzed. Meanwhile, we reviewed the literature, and the reported patients of renal cell carcinoma with urinary tract tumor thrombus were also included in our study. The basic information, clinical manifestations, treatment, pathological characteristics and follow-ups of all the patients were analyzed.@*RESULTS@#In our study, 6 patients from the two hospitals and 16 patients from previous literature reports were included. There were 13 males and 9 females with an average age of 54.7 years (22-79 years). Fifteen patients had renal cell carcinoma on the left side, 6 on the right side, and 1 on the unknown side. Gross hematuria was the most common chief complaint, including 18 patients. One patient complained of weight loss, 1 patient complained of microscopic hematuria, and 1 patient was found by ultrasound examination. Tumor thrombus was classified as grade Ⅰ in 9 cases (the tumor embolus protruded into the renal pelvis, but did not reach the ureteropelvic junction), grade Ⅱ in 10 cases (the tumor embolus protruded into the ureter, but not into the bladder), and grade Ⅲ in 3 cases (the tumor embolus passed through the ureter and protruded into the bladder). Only 11 patients were diagnosed with renal cell carcinoma before operation. Radical nephrectomy was performed in 9 cases and nephroureterectomy in 12 cases. In pathological diagnosis, there were 15 cases of clear cell renal cell carcinoma, 1 case of papillary renal cell carcinoma, 1 case of chromophobe cell carcinoma, 1 case of mixed cell renal cell carcinoma, 4 cases of renal cell carcinoma with undetermined classification. Eleven patients were followed up for 3-31 months, and 3 patients had lung metastasis within 6 months.@*CONCLUSION@#Renal cell carcinoma with urinary tract tumor thrombus is rare in clinic. It needs to be differentiated from renal pelvis carcinoma in diagnosis. The treatment principle can refer to general renal carcinoma. For locally advanced cases, complete resection is the best treatment, and its oncological prognosis needs more long-term and large-scale follow-up observation.

Villous adenoma is uncommonly seen in the urogenital tract and is even more rarely seen in the upper urinary tract and renal pelvis. Like colorectal adenomas, these neoplasms can transform into adenocarcinoma. The preoperative diagnosis is challenging due to their frequent association with hydronephrosis. Herein, we present the case of a villous adenoma of the renal pelvis in a 62-year-old man presenting with recurrent urinary tract infection. The computed tomography scan showed marked hydronephrosis but no suspicious mass in the right kidney. A laparoscopic right nephrectomy was performed. Gross examination revealed a dilated renal pelvis with an irregular exophytic lesion in the renal pelvis's upper surface. The histopathological examination showed slender, elongated villi with thin fibrovascular cores, consistent with villous adenoma morphology. Isolated villous adenomas have a favorable prognosis. However, the pathologist should undertake a search for an invasive component.

ABSTRACT Purpose: To investigate the association between preoperative retrograde pyelography (RGP), conducted to evaluate upper tract urothelial carcinoma (UTUC), and intravesical recurrence (IVR) after radical nephroureterectomy (RNU). Materials and Methods: Of 114 patients that underwent RNU, 72 patients without preoperative ureteroscopy and a history of bladder tumor were selectively enrolled. Variables associated with IVR were identified. Results: RGP was performed at a mean duration of 24.9 days prior to RNU in 41 (56.1%) of study subjects. During the mean follow-up period of 64.5 months, IVRs were identified in 32 (44.4%) patients at 22.3±18.8 (mean±SD) months after RNU. Despite similar tumor characteristics in the RGP and non-RGP groups, the incidence of IVR was considerably higher in the RGP group (63.4%) than in the non-RGP group (19.4%, p <0.001). The following variables differed significantly between the IVR and non-IVR groups: age (64.6±8.51 vs. 59.6±9.65 years), tumor location (lower or upper; 53.1% vs. 20%), tumor invasiveness (> pT2; 53.1% vs. 17.5%), preoperative hemoglobin (12.8±1.36 vs. 13.9±1.65), preoperative creatinine (1.29±0.32 vs. 1.11±0.22), and preoperative RGP (81.3% vs. 37.5%), respectively. Multivariate Cox regression model showed that tumor location (p=0.020, HR=2.742), preoperative creatinine level (p=0.004, HR=6.351), and preoperative RGP (p=0.045, HR=3.134) independently predicted IVR. Conclusion: Given the limitations of retrospective single-center series, performance of RGP before RNU was shown to have a negative effect on IVR after surgery.

This study aimed to further validate the prognostic role of fibrinogen in upper tract urothelial carcinoma (UTUC) in a large Chinese cohort. A total of 703 patients who underwent radical nephroureterectomy were retrospectively identified. Fibrinogen levels of ≥4.025 g l-1 were defined as elevated. Logistic regression analysis was performed to determine the association between fibrinogen and adverse pathological features. Kaplan-Meier analysis and Cox regression models were used to assess the associations of fibrinogen with cancer-specific survival (CSS), disease recurrence-free survival (RFS), and overall survival (OS). Harrell c-index and decision curve analysis were used to assess the clinical utility of multivariate models. The median follow-up duration was 42 (range: 1-168) months. Logistic regression analysis revealed that elevated fibrinogen was associated with higher tumor stage and grade, lymph node involvement, lymphovascular invasion, sessile carcinoma, concomitant variant histology, and positive surgical margins (all P < 0.05). Multivariate Cox regression analysis demonstrated that elevated fibrinogen was independently associated with decreased CSS (hazard ratio [HR]: 2.33; P < 0.001), RFS (HR: 2.09; P < 0.001), and OS (HR: 2.09; P < 0.001). The predictive accuracies of the multivariate models were improved by 3.2%, 2.0%, and 2.8% for CSS, RFS, and OS, respectively, when fibrinogen was added. Decision curve analysis showed an added benefit for CSS prediction when fibrinogen was added to the model. Preoperative fibrinogen may be a strong independent predictor of worse oncologic outcomes in UTUC; therefore, it may be valuable to apply this marker to the current risk stratification in UTUC.

Precision medicine plays a key role in urological oncology practice nowadays, with the breakthrough of the poly (ADP-ribose) polymerase inhibitors (PARPi), which play a critical role in different DNA damage repair (DDR) pathways, the immune checkpoint inhibitors, the genomic expression profiles and current genome manipulation-directed targeted therapy. Information and technology (IT) are set to change the way we assess and treat patients and should be reviewed and discussed. The aim of the present article is to demonstrate a detailed revision on precision medicine, including novel therapeutic targets, genomic markers, genomic stratification of urological patients, and the top-notch technological breakthroughs that could change our clinical practice We performed a review of the literature in four different databases (PubMed, Embase, Lilacs, and Scielo) on any information concerning prostate, bladder, kidney and urothelial cancer novel treatments with PARPi, immune checkpoint inhibitors (ICIs), targeted therapy with fibroblast growth factor receptor inhibitors (FGFRi), and theranostics with prostate-specific membrane antigen (PSMA) targeted monoclonal antibodies. Artificial intelligence, machine learning, and deep learning algorithm in urological practice were also part of the search. We included all articles written in English, published within the past 7 years, that discussed outstanding therapies and genomics in urological cancer and artificial intelligence applied to urology. Meanwhile, we excluded articles with lack of a clear methodology and written in any other language than English. One-hundred and twenty-six articles of interest were found; of these, 65 articles that presented novel treatments of urological neoplasms, discussed precision medicine, genomic expression profiles and biomarkers in urology, and latest deep learning and machine learning algorithms as well as the use of artificial intelligence in urological practice were selected. A critical review of the literature is presented in the present article. Urology is a constantly changing specialty with a wide range of therapeutic breakthroughs, a huge understanding of the genomic expression profiles for each urological cancer and a tendency to use cutting-edge technology to treat our patients. All of these major developments must be analyzed objectively, taking into account costs to the health systems, risks and benefits to the patients, and the legal background that comes with them. A critical analysis of these new technologies and pharmacological breakthroughs should be made before considering changing our clinical practice. Nowadays, research needs to be strengthened to help us improve results in assessing and treating our patients
La medicina de precisión juega un rol fundamental en la práctica clínica de la urologia oncológica en la actualidad, con el desarrollo de los inhibidores de la poli (ADP-ribosa) polimerasa (PARPi), que juegan un papel fundamental en las distintas vías del reparo del ADN dañado (RAD), los inhibidores del punto de chequeo inmune (ICI), los perfiles de expresión genómicos, y la terapia blanco-dirigida a la manipulación genómica. El desarrollo tecnológico y la informática están cambiando la forma como evaluamos y tratamos a los pacientes, y se debe discutir y revisar a detalle. El objetivo de este artículo es hacer una revisión detallada acerca de la medicina de precisión, genómica, y los avances tecnológicos en nuestro campo. Realizamos una revisión de la literatura en cuatro bases de datos diferentes (PubMed, Embase, Lilacs, y Scielo), buscando cualquier información relacionada con cáncer de próstata, vejiga, riñón y carcinoma urotelial, tratamientos novedosos con PARPi, ICI, terapia-blanco con inhibidores del receptor del factor de crecimiento de los fibroblastos (FGFRi) y teragnósticos con anticuerpos monoclonales dirigidos al antígeno de membrana específico de la próstata (AMEP). Inteligencia artificial, aprendizaje de máquinas y algoritmos de aprendizaje profundo en la práctica urológica también fueron revisados. Incluimos artículos escritos en inglés, publicados dentro de los últimos 7 años, que abordaran terapias novedosas y genómica en cáncer urológico e inteligencia artificial aplicada a la urología. Excluimos artículos con falta de una metodología adecuada y escritos en cualquier idioma diferente al inglés. En total, 126 artículos de interés fueron encontrados, y, de estos seleccionamos 65 artículos que reportaban tratamientos novedosos para neoplasias urológicas, discutían medicina de precisión y perfiles de expresión genómica y bio-marcadores en urología, algoritmos de aprendizaje profundo, aprendizaje de máquina, y el uso de inteligencia artificial en la práctica urológica. Se hizo una revisión crítica de la literatura que se presenta en este artículo. La urología es una especialidad constantemente en cambio, con un gran rango de avances terapéuticos, un gran conocimiento de los perfiles de expresión genómica para cada cáncer urológico, y una tendencia a utilizar tecnología de punta para estudiar y tratar a nuestros pacientes. Todos estos desarrollos se deben analizar objetivamente, y hay que tener en cuenta los costos al sistema de salud, los riesgos y beneficios para los pacientes, y el contexto legal que implica cada uno. Hasta la fecha, estos avances tecnológicos y farmacológicos se deben analizar con cautela antes de vernos en la posición de cambiar nuestra práctica clínica. Se debe fortalecer la investigación médica para mejorar los resultados en el tratamiento y abordaje de nuestros pacientes.

ABSTRACT Objectives: To investigate whether Glasgow Prognostic Score has prognostic significance in patients with upper urinary urothelial carcinoma. Patients and methods: We retrospectively reviewed the clinical records of 74 patients with upper urinary urothelial carcinoma. We set the cut-off value for C-reactive protein as 1.0mg/dL, and 3.5mg/dL for albumin as Glasgow Prognostic Score. Their blood data including albumin and C-reactive protein for Glasgow Prognostic Score and cytokeratin 19 fragment 21-1 as a tumor marker were measured before starting treatment. The patients were stratified into three groups with Glasgow Prognostic Score: The Group-1, albumin ≥3.5g/dL and C-reactive protein < 1.0mg/dL; Group-2, albumin < 3.5g/dL or C-reactive protein ≥1.0mg/dL; Group-3, albumin < 3.5g/dL and C-reactive protein ≥1.0mg/dL. Results: The median follow-up for all patients was 26.9 months (range: 10.9-91.1 months), during which 37 (50%) patients died. There was a significant difference in the estimated survival rate among the 3 groups stratified by Glasgow Prognostic Score. The estimated survival rate in the Group-1 was significantly higher than those in Groups 2 and 3. In the univariate analysis C-reactive protein, serum cytokeratin 19 fragment 21-1 and Glasgow Prognostic Score were significant predictors of overall survival. On the multivariate analysis, serum cytokeratin 19 fragment 21-1 and Glasgow Prognostic Score were independently associated with shorter overall survival. Conclusion: Our review suggests Glasgow Prognostic Score may play as a prognostic predictor for upper urinary urothelial carcinoma.

OBJETIVO: interpretar os sentidos atribuídos à sobrevivência ao câncer entre adoecidos adultos e idosos. MÉTODO: estudo exploratório com abordagem qualitativa com método narrativo e referencial da antropologia médica. Participaram do estudo 14 indivíduos adultos e idosos que já haviam concluído o tratamento primário há pelo menos três meses em um hospital universitário e que tinham o diagnóstico de câncer urológico (bexiga, próstata, rim, testículo). Realizou-se entrevista semiestruturada no domicílio dos participantes no período de outubro de 2014 a novembro de 2015 e após transcrição foram analisados segundo análise temática indutiva. RESULTADOS: após análise e interpretação dos dados obtiveram-se duas principais categorias - da perda do autocontrole e a incerteza da recorrência da doença à vigilância do corpo; e o segredo da sobrevivência ao câncer: o sentimento de otimismo e esperança. CONCLUSÃO: após interpretação dos sentidos ficou evidente que a sobrevivência ao câncer é um processo permeado por perda do autocontrole, incerteza, medo da recorrência, associado a multimorbidade e vigilância, mas que cedo ou tarde pode conduzir o sobrevivente do câncer a um crescimento pessoal, atribuindo mais valor à sua vida e sendo otimista.(AU)
Objective: to interpret the meanings attributed to cancer survival among sick adults and the elderly. Method: exploratory study with qualitative approach with narrative and referential method of medical anthropology. Fourteen adult and elderly individuals who had completed primary treatment for at least three months in a university hospital and had a diagnosis of urological cancer (bladder, prostate, kidney, testis) participated in the study. A semi-structured interview was conducted at the participants' homes from October 2014 to November 2015 and after transcription were analyzed according to inductive thematic analysis. Results: after analysis and interpretation of the data, two main categories were obtained - from loss of self-control and uncertainty of disease recurrence to body surveillance; and the secret of cancer survival: the feeling of optimism and hope. Conclusion: After interpretation of the senses it became evident that cancer survival is a process permeated by loss of self-control, uncertainty, fear of recurrence, associated with multimorbidity and vigilance, but that sooner or later it may lead the cancer survivor to personal growth, attaching more value to your life and being optimistic.(AU)
Objetivo: interpretar los significados atribuidos a la supervivencia al cáncer entre enfermos adultos y adultos mayores. Método: estudio exploratorio de enfoque cualitativo con método narrativo y referencial de la antropología médica. En el estudio participaron catorce personas adultas y de edad avanzada que habían completado el tratamiento primario durante, al menos, tres meses en un hospital universitario y tenían un diagnóstico de cáncer urológico (vejiga, próstata, riñón, testículos). Se realizó una entrevista semiestructurada en los hogares de los participantes entre octubre de 2014 y noviembre de 2015 y, después de su transcripción, los datos se analizaron de acuerdo con el análisis temático inductivo. Resultados: luego del análisis e interpretación de datos, se obtuvieron dos categorías principales: desde la pérdida de autocontrol y la incertidumbre de la recurrencia de la enfermedad hasta la vigilancia corporal; y el secreto de la supervivencia al cáncer: el sentimiento de optimismo y esperanza. Conclusión: después de la interpretación de los sentidos, se hizo evidente que la supervivencia al cáncer es un proceso impregnado de pérdida de autocontrol, incertidumbre, miedo a la recurrencia, asociado con la multimorbilidad y la vigilancia, pero que tarde o temprano puede llevar al sobreviviente al crecimiento personal, valorado más la vida y siendo optimista.(AU)

OBJECTIVE@#To compare the efficacy and safety of complete transperitoneal laparoscopic nephroureterectomy (CTNU) and traditional retroperitoneoscopic nehroureterectomy (TRNU) for the management of upper urinary tract urothelial carcinoma(UTUC).@*METHODS@#We retrospectively collected the clinical data of UTUC patients who underwent CTNU or TRNU surgery from January 2011 to December 2018 in Peking University First Hospital and Fujian Provincial Hospital, and compared the clinical characteristics, perioperative parameters, and follow-up results between the CTNU and TRNU surgeries.@*RESULTS@#Finally, a total of 266 cases were included, with 94 cases in the CTNU group and 172 cases in the TRNU group. The proportion of left side lesions was bigger in TRNU group when compared with CTNU group (P<0.05). No significant differences were observed in clinical characteristics, such as age, gender, body mass index (BMI), American society of anesthesiologists score (ASA score) and tumor laterality. All surgery procedures were completed. The vascular resparing was performed by reason that left arteria renalis was injured accidently during surgical operation in one case of TRNU group. No serious complications were observed in both CTNU and TRNU groups. In CTNU group, operating time was (202.9±76.7) min, estimated blood loss was (68.4±73.3) mL, drainage duration was (3.9±1.5) d, drainage volume was (181.7±251.5) mL, and postoperative hospital stay was (7.8±4.1) d. In TRNU group, operating time was (203.5±68.7) min, estimated blood loss was (130.2±252.1) mL, drainage duration was (4.3 ±1.6) d, drainage volume was (179.1±167.5) mL, and postoperative hospital stay was (8.2±3.7) d. The estimated blood loss in CTNU group was significantly less than that in TRNU group (P=0.005).The median follow-up time was 39 months (range: 1-88 months). The 5-year overall survival rate (OS), cancer specific survival rate (CSS), intra-vesical recurrence free survival rate (IvRFS), disease free survival rate (DFS) of CTNU group was 75.6%, 86.9%, 73.8%, 57.5%, respectively. The OS, CSS, IvRFS and DFS of TRNU group was 66.3%, 83.5%, 75.9%, 58.6%, respectively.No significant differences were observed in the OS, CSS, IvRFS and DFS between the CTNU and TRNU groups.@*CONCLUSION@#CTNU technique is a safe and effective surgical option, and further prospective randomized controlled trial is needed for further evaluation.

OBJECTIVE@#To identify the effect of preoperative anemia on the prognosis of patients with upper tract urothelial carcinoma (UTUC) following radical nephroureterectomy.@*METHODS@#Clinicopathological and prognosis data on 686 patients with UTUC who underwent RNU at Peking University First Hospital between January 2000 and December 2013 were retrospectively analyzed. Preoperative anemia was defined as hemoglobin <130 g/L in men and <120 g/L in women based on the World Health Organization classification. The Kaplan-Meier method with log-rank test was applied to estimate the effect of anemia on survival. The associations of clinicopathologic features with overall survival and cancer-specific survival were evaluated using univariate and multivariate Cox regression models.@*RESULTS@#There were 303(44.2%, 303/686) male and 383(55.8%, 383/686) female patients, and the median age was 68 years (interquartile range: 60-74 years). In all, 320 (46.6%, 320/686) patients were anemic before surgery. The median follow-up duration was 47 months. In all, 160 (23.3%) patients died, 141 (20.6%) died of cancer and 19 (2.7%) died of other disease or accidents. Preoperative anemia was associated with gender (P=0.002), age (P<0.001), lymph node positive (P=0.026), increased tumor grade (P=0.018), concomitant carcinoma in situ (P=0.038), tumor necrosis (P=0.007) and poor renal function (P<0.001). In univariate analysis, overall mortality was correlated with pre-operative anemia (P<0.001), gender (P=0.009), hydronephrosis (P=0.024), tumor stage (P<0.001), lymph node positive (P<0.001), tumor grade (P<0.001), tumor architecture(P<0.001), sarcomatoid differentiation (P=0.013), history of ureteroscope (P=0.033) and tumor hemorrhage (P<0.001); cancer-specific mortality was correlated with preoperative anemia (P=0.001), gender (P=0.001), hydronephrosis (P=0.043), tumor stage (P<0.001), lymph node positive (P<0.001), tumor grade (P<0.001), tumor architecture (P<0.001), sarcomatoid differentiation (P=0.016), history of ureteroscope (P=0.028) and tumor hemorrhage (P=0.003). A multivariate Cox proportional hazards model indicated that preoperative anemia was an independent prognositic predictor for overall mortality (P<0.001, HR=1.861) and cancer-specific mortality (P=0.003, HR=1.688).@*CONCLUSION@#The preoperative anemia is an independent risk factor for cancer-specific survival and overall survival. Hemoglobin levels should be considered during patient counseling and in decision-making for further therapy.

Bladder cancer (BC) is the most common urinary tract neoplasm through the world. Around 80% of BC patients present with nonmuscle invasive bladder cancer (NMIBC). Transurethral resection (TUR) of the bladder is the standard treatment to remove cancer tissue from patients with NMIBC. Unfortunately, BC frequently recurs after TUR. At least half of the patients diagnosed with NMIBC experience tumor recurrence after receiving the appropriate treatment. High recurrence rate is one representative characteristic of BC. Therefore, intravesical therapy after TUR is often performed in patients with NMIBC to prevent recurrence. In recent years, various therapeutic agents have been examined in preclinical and clinical trials for use in post-TUR adjuvant intravesical therapy. However, intravesical therapies using anticancer drug are relative safe but, lower anticancer effects and bacillus Calmette-Guérin has a strong anticancer effect but high frequency of adverse events. So, there are growing interests for prediction of recurrence of NMIBC. Until now, many studies were performed for the recurrence prediction markers of NMIBC with cancer tissues instead of blood or urine. In this review, we discuss the predictive value of various genetic, protein markers in cancer tissues, and molecular markers in blood and urine for the recurrence of the NMIBC.
