Resumen Antecedentes. Los efectos inducidos por la COVID-19 en pacientes con cáncer de vejiga primario no están aclarados actualmente. Objetivo. Investigar los efectos de la pandemia en el diagnóstico, el tratamiento y el seguimiento del cáncer de vejiga primario. Método. Se realizó un análisis retrospectivo unicéntrico de todos los pacientes que se sometieron a procedimientos diagnósticos y quirúrgicos por cáncer primario de vejiga durante noviembre de 2018 y julio de 2021. Se incluyeron 275 pacientes en el estudio. Los pacientes fueron asignados a uno de dos grupos: pre-COVIDBC (antes de la pandemia) o COVIDBC (durante la pandemia). Resultados. Los pacientes con cáncer de vejiga diagnosticados durante la pandemia se encontraban en su mayoría en estadios más altos (T2) (p = 0.04), el grupo de riesgo era más alto en el cáncer de vejiga no invasivo del músculo (p = 0.02), y la recurrencia y las puntuaciones de progresión aumentaron (p = 0.001) en comparación con antes del período pandémico. Además, el tiempo hasta la cirugía desde el diagnóstico (p = 0.001) y la duración de los síntomas (p = 0.04) aumentaron considerablemente durante la pandemia, y la tasa de seguimiento disminuyó significativamente (p = 0.03). Conclusiones. Destaca el aumento significativo del cáncer de vejiga invasivo del músculo y del cáncer de vejiga no invasivo del músculo de muy alto riesgo durante la pandemia.

Abstract Purpose. The COVID-19-induced effects of primary bladder cancer (BC) patients have not yet been clarified. The aim of this study was to investigate the effects of the pandemic on the diagnosis, treatment, and follow-up of primary BC patients. Material and methods. A retrospective single-center analysis was made of all patients who underwent diagnostic and surgical procedures due to primary BC between November 2018 and July 2021. A total of 275 patients were identified and allocated to one of the groups: Pre-COVIDBC (BC diagnosed before the COVID-19 pandemic) or COVIDBC (during the pandemic). Results. The BC patients diagnosed during the pandemic were mostly at higher stages (T2) (p = 0.04), the risk of non-muscle invasive BC (NMIBC) was higher (p = 0.02), and recurrence and progression scores were increased (p = 0.001) compared to patients diagnosed before the pandemic. The time to surgery from diagnosis (p = 0.001) and symptom duration (p = 0.04) were significantly prolonged during the pandemic and the rate of follow-up significantly decreased (p = 0.03). Conclusions. The study results highlight the significant increase in muscle invasive BC and the very high risk of NMIBC in patients presenting during the COVID-19 pandemic.

Abstract Background and objectives: Patients undergoing radical prostatectomy are at increased risk of Acute Kidney Injury (AKI) because of intraoperative bleeding, obstructive uropathy, and older age. Neutrophil Gelatinase-Associated Lipocalin (NGAL) may become important for diagnosis of postoperative AKI after urogenital oncosurgery. The objective of this study was to evaluate and compare the efficacy of NGAL as a predictor of AKI diagnosis in patients who underwent Retropubic Radical Prostatectomy (RRP) and Robot-Assisted Laparoscopic Prostatectomy (RALP) for prostate cancer. Methods: We included 66 patients who underwent RRP (n = 32) or RALP (n = 34) in this prospective, comparative, nonrandomized study. Patients’ demographic data, duration of surgery and anesthesia, amount of blood products, vasopressor therapy, intraoperative blood loss, fluid administration, length of hospital stay, creatinine, and plasma NGAL levels were recorded. Results: Intraoperative blood loss, crystalloid fluid administration, and length of hospital stay were significantly shorter in RALP. There was no statistically significant difference between the groups in terms of intraoperative blood transfusion. Postoperative creatinine and plasma NGAL levels were increased in both groups. The 6-h NGAL levels were higher in RRP (p = 0.026). The incidence of AKI was 28.12% in RRP and 26.05% in RALP, respectively. The NGAL level at 6 hours was more sensitive in the early diagnosis of AKI in RALP. Conclusion: Although postoperative serum NGAL levels were increased in both RRP and RALP, the 6-h NGAL levels were higher in RRP. RALP was associated with fewer intraoperative blood loss and fluid administration, and shorter length of hospital stay.

Resumen Objetivo: Nuestro objetivo fue investigar la importancia del tiempo para volver a estadificar la resección transuretral (re-RTU) en las tasas de recurrencia y progresión en pacientes con cáncer de vejiga no músculo invasivo de alto riesgo como un estudio prospectivo aleatorizado. Método: Los pacientes se separaron aleatoriamente en 3 grupos de acuerdo con el tiempo de Re-TUR. En el grupo 1, 2 y 3, el intervalo de tiempo entre la RTU inicial y la nueva fue de 14 a 28 días, 29 a 42 días y 43 a 56 días, respectivamente. Cox para evaluar el efecto del tiempo desde la RTU inicial hasta la nueva RTU sobre los resultados oncológicos. Resultados: Veinte pacientes del grupo 1, 22 pacientes del grupo 2, 29 pacientes del grupo 3 completaron el estudio. Los gráficos de Kaplan-Meier no mostraron diferencias en las tasas de SLR y SLP entre los tres grupos. El análisis de regresión de Cox demostró que solo se encontró que el número de tumores era un factor pronóstico en las tasas de RFS. Conclusión: Nuestro estudio prospectivo demostró que los lapsos de tiempo desde la RTU inicial hasta la nueva RTU no afectaron significativamente las tasas de SLR y SLP.

Abstract Objective: We aimed to investigate the significance of time to re-staging transurethral resection (re-TUR) on recurrence and progression rates in patients with high-risk non-muscle-invasive bladder cancer as a prospective randomized study. Methods: The patients were randomly separated into three groups according to Re-TUR timing. In Groups 1, 2, and 3, the time interval between initial and re-TUR was 14-28 days, 29-42 days, and 43-56 days, respectively. Cox regression analysis was used to assess the effect of time from initial TUR to re-TUR on oncological outcomes. Results: Twenty patients in Group 1 (14-28 days), 22 patients in Group 2 (29-42 days), and 29 patients in Group 3 (43-56 days) completed the study. Kaplan–Meier plots showed no differences in recurrence-free survival (RFS) and progression-free survival (PFS) rates between the three groups. Cox regression analysis demonstrated that only tumor number was found to be a prognostic factor on RFS rates. Conclusion: Our prospective study demonstrated that time laps from initial TUR to re-TUR did not significantly affect on RFS and PFS rates.

Resumen Propósito: El objetivo de este estudio fue investigar los efectos de la pandemia COVID-19 en la derivación, el diagnóstico, el tratamiento y el seguimiento de los TCG. Métodos: Se realizó un análisis retrospectivo unicéntrico de todos los pacientes que se sometieron a procedimientos diagnósticos y quirúrgicos debido a TCG entre septiembre de 2018 y septiembre de 2021. Resultados: Se inscribieron 65 pacientes en el estudio dividiéndolos en dos grupos como antes de la pandemia (Pre- CovGCT) y durante la pandemia (CovGCT). Se evaluaron y compararon 33 pacientes en el grupo Pre-CovGCT y 32 pacientes en el grupo CovGCT. Se observó un aumento significativo de la duración de los síntomas (p = 0.018), la duración entre el diagnóstico y el procedimiento quirúrgico (p = 0.028) y el riesgo de metástasis oculta de los tumores en estadio 1 (p = 0.05) durante el período pandémico. Conclusiones: Nuestro estudio mostró que la duración de los síntomas y la duración entre el diagnóstico y el procedimiento quirúrgico se prolongaron en los pacientes con TCG diagnosticados durante el período pandémico. Además, se ha observado un mayor riesgo de metástasis oculta en pacientes con TCG en estadio 1. Subrayamos la importancia de concienciar a los pacientes sobre el ingreso hospitalario sin demora en presencia de síntomas de cáncer de testículo y recomendamos tener cuidado de no retrasar el proceso de tratamiento.

Abstract Purpose: The aim of this study was to investigate the effects of the COVID-19 pandemic on the referral, diagnosis, treatment, and follow-up of germ cell tumor (GCT). Methods: A retrospective single-center analysis of all patients who underwent diagnostic and surgical procedures due to GCT was performed from September 2018 to September 2021. Results: 65 patients were enrolled into the study by dividing them into two groups as before pandemic (Pre-CovGCT) and during the pandemic (CovGCT). 33 patients in the Pre-CovGCT group and 32 patients in the CovGCT group were evaluated and compared. A significant increase was observed for symptom duration (p = 0.018), the duration between diagnosis and surgical procedure (p = 0.028), and occult metastasis risk of stage 1 tumors (p = 0.05) during the pandemic period. Conclusions: The duration of symptoms and the duration between the diagnosis and surgical procedure were prolonged in GCT patients diagnosed during the pandemic. Furthermore, an increased risk of occult metastasis has been observed in stage 1 GCT patients. We underline the importance of raising the awareness of patients about admission to the hospital without delay in the presence of testicular cancer symptoms and recommend to be careful not to delay the treatment process.
