Summary: | Gleason score biopsy undergrading (GSBU) can have an impact on the management and prognosis of patients with Prostate Cancer (PC). We analyze the possible impact of time and other clinical and analytical factors in the appearance of GSBU in our series.
Ambispective, multicenter study of 1955 patients with localized PC undergoing radical prostatectomy (RP) between 2005 and 2018. Descriptive statistics and hypothesis testing are reported by univariate and multivariate analyses.
Mean age 63.69 (44–80) years, median PSA 8.70ng / ml (1.23–99). GSBU was observed in 34.7% of the entire cohort. In 72.8% of the cases, the GSBU occurred in one consecutive Gleason score, with the progression from 3+3 to 3+4 being the most frequent (289 patients, 47.6%). Performing RP 90–180 days before or after the biopsy does not have an impact on its undergrading in any of the groups. In the univariate and multivariate analysis, the presence of tumor or pathological rectal examination in both lobes, the tumor load ≥50% of cylinders and a DPSA≥0.20, showed independent discriminative capacity to select patients who presented GSBU.
The time from biopsy to RP did not show impact on GSBU. The number of affected cylinders, bilateral tumor and DPSA are easily accessible parameters that can help us select patients with greater probability of presenting GSBU.
La infragradación del Grado de Gleason de la biopsia (IGGB) puede impactar en el manejo y pronóstico de los pacientes con Cáncer de Próstata (CP). Se analiza el posible impacto del tiempo y otros factores clínico analíticos y la aparición de IGBB en nuestra serie.
Estudio multicéntrico ambispectivo de 1955 pacientes con CP localizado sometidos a prostatectomía radical entre 2005 y 2018. Se utiliza estadística descriptiva y pruebas de contraste de hipótesis con análisis uni y multivariados para comunicar los resultados.
Edad media 63,69 (44-80) años, mediana de PSA 8,70ng/ml (1,23-99). Se observa IGGB en el 34,7% de toda la muestra. En el 72,8% de los casos la IGGB fue en un único punto consecutivo del grado de Gleason, siendo el paso de 3+3 a 3+4 el más frecuente (289 pacientes, 47,6 %). La realización de PR antes o después de 90-180 días desde la biopsia no impacto en la infragradación de la misma en ninguno de los grupos. En el análisis uni y multivariante la presencia de tumor o tacto rectal patológico en ambos lóbulos, la carga tumoral ≥50% de los cilindros totales y una DPSA≥0.20 mostraron capacidad discriminativa independiente pa |
