RESUMO

INTRODUCTION AND OBJECTIVES: To evaluate whether there is any difference between immediate postoperative instillation of intravesical chemotherapy (IPOIC) and continuous saline bladder irrigation (CSBI) in terms of bladder cancer (BC) recurrence in patients with primary low- or intermediate-risk non-muscle-invasive BC (NMIBC). MATERIALS AND METHODS: Medical records of 1482 patients who underwent transurethral resection of bladder tumor between March 1994 and August 2020 were reviewed retrospectively. Patients were divided into two groups according to IPOIC and/or CSBI administration status [Group-1 = CSBI alone; Group-2 = CSBI following IPOIC]. Low- and intermediate-risk NMIBC patients were also divided into subgroups according to IPOIC and/or CSBI administration status. RESULTS: A total of 594 patients with primary NMIBC were included. Of the patients, 86 (14.5%) were female and 508 (85.5%) were male with a median age of 69 (60-78) years. The frequency of patients in Group-1 and Group-2 were 361 (60.8%) and 233 (39.2%), respectively. Recurrent disease was observed in 213 (35.9%) patients. There was no difference between the groups when they were compared for recurrent disease frequency, median time to first recurrence and frequency of recurrence within first 12 months (P = .064, P = .671, and P = .145, respectively). Disease recurrence rates in low-risk NMIBC patients was lower when they were treated with "CSBI following IPOIC" when compared to "CSBI alone" (P = .042). However, no difference was observed in low-risk NMIBC subgroups when they were compared for pathological features of recurrent tumors such as number, size, grade, stage, and presence of carcinoma in situ (P > .05, for each). CONCLUSIONS: "CSBI following IPOIC" combination was not superior to "CSBI alone" for preventing adverse pathological outcomes in recurrent low- and intermediate-risk NMIBC.

RESUMO

Introducción y objetivos: Este estudio tiene como objetivo investigar la relación entre la invasión perineural (IPN) en la biopsia de próstata con aguja dirigida (BD) y/o sistemática (BS) y las características patológicas adversas del cáncer de próstata (CaP) en los especímenes de prostatectomía.Materiales y métodos: Se incluyeron un total de 95 pacientes varones que recibieron una BD transperineal y/o una BS concomitante, tratados posteriormente con prostatectomía radical asistida por robot para CaP entre octubre de 2015 y junio de 2020. Se calculó el rendimiento de la IPN como prueba de clasificación (sensibilidad, especificidad, valores predictivos positivos y negativos) y su correlación con el CaP clínicamente significativo, la positividad del margen quirúrgico, la extensión extraprostática y la invasión de las vesículas seminales en la prostatectomía.Resultados: La edad media de los pacientes era 65 (60-70) años. Se realizó BD y BS concomitante en 78 (82,1%) pacientes, mientras que 16 (16,8%) pacientes recibieron solo BS y uno (1,1%) solo BD. La frecuencia de IPN en la BD y BS fue de 17 (21,5%) y 32 (34,0%), respectivamente. Los valores de especificidad/predictivos negativos de la IPN para positividad del margen quirúrgico, extensión extraprostática e invasión de las vesículas seminales fueron 79,7/88,7%, 92,5/79,0% y 83,3/96,8%, en la BD, y 71,1/87,1%, 80,7/74,2% y 69,5/91,9%, en la BS, respectivamente. También hubo una correlación estadísticamente significativa entre la IPN en la biopsia y la positividad del margen quirúrgico, la extensión extraprostática y la invasión de las vesículas seminales en la prostatectomía, así como en cuanto al grupo de grado ISUP y el estadio pT.Conclusiones: La ausencia de IPN en la biopsia de próstata con aguja puede predecir un CaP localizado con un estadio pT≤2c y márgenes quirúrgicos negativos; por el contrario, su presencia parece ser un indicador de factores desfavorables en la patología final (AU)


Introduction and objectives: This study aims to investigate the relationship between perineural invasion (PNI) in targeted (TBx) and/or systematic (SBx) prostate needle biopsy and adverse pathological features of prostate cancer (PCa) in prostatectomy specimens.Materials and methods: A total of 95 male patients who underwent transperineal TBx and/or concomitant SBx subsequently treated with robot-assisted radical prostatectomy for PCa between October 2015 and June 2020 were included. The performance of PNI as a classification test (sensitivity, specificity, positive and negative predictive values) and its correlation with clinically significant PCa, surgical margin positivity, extraprostatic extension, and seminal vesicle invasion in prostatectomy were computed.Results: The median age of the patients was 65 (60-70) years. TBx and concomitant SBx were performed in 78 (82.1%) patients, while 16 (16.8%) patients underwent SBx alone and one (1.1%) patient underwent TBx alone. The frequency of PNI in TBx and SBx was 17 (21.5%) and 32 (34.0%), respectively. The specificity/negative predictive values of PNI for surgical margin positivity, extraprostatic extension, and seminal vesicle invasion were 79.7/88.7%, 92.5/79.0%, and 83.3/96.8%, in TBx, and 71.1/87.1%, 80.7/74.2%, and 69.5/91.9%, in SBx, respectively. There was also a statistically significant correlation between PNI in biopsy and surgical margin positivity, extraprostatic extension, and seminal vesicle invasion in prostatectomy as well as the ISUP grade group and pT stage.Conclusions: The absence of PNI in prostate needle biopsy may predict localized PCa with a pT stage≤2c and negative surgical margins in contrast to its presence which appears to be an indicator of unfavorable factors in final pathology (AU)

RESUMO

INTRODUCCIÓN Y OBJETIVOS: El objetivo de este estudio retrospectivo fue analizar la densidad de los ganglios linfáticos (GL) en la disección de los GL retroperitoneales (DGLRP) para evaluar la masa residual tras quimioterapia como factor predictivo de recurrencia en pacientes con cáncer testicular de células germinales (CTCG). MATERIALES Y MÉTODOS: Se revisaron retrospectivamente los datos de 185 pacientes operados por CTCG entre diciembre del 2004 y febrero del 2017. Se calculó la densidad de los GL. Los pacientes se compararon estadísticamente en términos de características demográficas, características tumorales, niveles de marcadores tumorales séricos, estrategias de tratamiento y resultados patológicos según los subtipos de CTCG. Se realizó un análisis de correlación para determinar los parámetros relacionados con la enfermedad recurrente. RESULTADOS: La mediana de seguimiento fue de 79 (31-179) meses y la mediana de edad de los pacientes fue de 23 (16-71). El tamaño medio del tumor fue de 4 (1-18) cm. Cinco (2,7%) pacientes tenían enfermedad metastásica en el momento del diagnóstico inicial. Se detectó seminoma, TCG no seminomatoso y CTCG de tipo mixto en 62 (33,5%), en 60 (32,4%) y en 63 (34,1%) pacientes, respectivamente. Tras la orquiectomía inguinal, 48 (25,9%) pacientes recibieron seguimiento, 126 (68,1%) pacientes se sometieron a quimioterapia y 11 (5,9%) pacientes recibieron radioterapia. Un total de 21 (11,4%) pacientes se sometieron a DGLRP posquimioterapia. Se observó recurrencia precoz y tardía en 3 (1,6%) y 2 (1,1%) pacientes, respectivamente. Se encontró una correlación negativa leve/moderada, pero significativa, entre la recurrencia y el número de GL con depósitos metastásicos y la densidad de los GL (r = -0,490, p = 0,024 y r = -0,450, p = 0,041, respectivamente). CONCLUSIONES: Hubo una correlación negativa entre el número de GL con depósitos metastásicos y la densidad de GL con la enfermedad recurrente


INTRODUCTION AND OBJECTIVES: In this retrospective study, we aimed to evaluate lymph node (LN) density in retroperitoneal lymph node dissection (RPLND) to analyze whether residual mass after chemotherapy might behave as predicting factor for recurrence in patients with germ cell testicular cancer (GCTC). MATERIALS AND METHODS: The data of 185 patients that were operated between 12/2004 and 02/2017 because of GCTC were reviewed retrospectively. LN density was calculated. The patients were compared statistically in terms of demographic features, tumor characteristics, serum tumor marker levels, treatment strategies, and pathological results according to GCTC subtypes. Correlation analysis was performed to determine the parameters related to recurrent disease. RESULTS: The median follow-up was 79 (31-179) months and the median age of the patients was 23 (16-71). The median tumor size was 4 (1-18) cm. Five (2.7%) patients had metastatic disease at initial diagnosis. Seminoma, non-seminomatous-GCT and mix type-GCTC was detected in 62 (33.5%), 60 (32.4%) and 63 (34.1%) patients, respectively. Following inguinal orchiectomy, 48 (25.9%) patients underwent follow-up, 126 (68.1%) patients underwent chemotherapy and 11 (5.9%) patients underwent radiotherapy. A total of 21 (11.4%) patients underwent post-chemotherapy RPLND. Early and late recurrence was seen in 3 (1.6%) and 2 (1.1%) of the patients, respectively. A mild to moderate, negative, but significant correlation was found between the recurrence and the number of LNs containing metastatic deposits and LN density (r = -0.490, P = .024 and r = -0.450, P=.041, respectively). CONCLUSIONS: There was a negative correlation between the number of LNs containing metastatic deposits and LN density and recurrent disease
