The impact of time from biopsy to radical prostatectomy on Gleason score undergrading and other related factors. / Impacto del tiempo desde la biopsia a la prostatectomía radical en la infragradación del grado de Gleason y análisis de factores relacionados.

INTRODUCTION: Gleason score biopsy undergrading (GSBU) can have an impact on the management and prognosis of patients with prostate cancer. We analyze the possible impact of time and other clinical and analytical factors in the appearance of GSBU in our series. PATIENTS AND METHOD: Ambispective, multicenter study of 1955 patients with localized prostate cancer undergoing radical prostatectomy between 2005 and 2018. Descriptive statistics and hypothesis testing are reported by univariate and multivariate analyses. RESULTS: Mean age 63.69 (44-80) years, median PSA 8.70 ng / 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 radical prostatectomy 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. CONCLUSIONS: The time from biopsy to radical prostatectomy 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.

Municipal distribution and trends in bladder cancer incidence in health area of León, Spain (1996-2010).

OBJECTIVE: Spain is a country where bladder cancer incidence and mortality rates are some of the highest in the world. The aim of this study is to know the incidence, trends and geographical distribution of bladder cancer in the health area of León. MATERIAL AND METHODS: the new cases of bladder cancer (CIE-188) in patients residing in the health area of León and registered in the Hospital Tumor Registry of the Centro Asistencial Universitario in León (Spain) between 1996-2010 were included in this study. Triennial crude incidence and adjusted incidence rates to the worldwide and European population were calculated. Population data of the municipalities of Leon (Spain) were obtained from National Institute of Statistic of Spain (INE, Instituto Nacional de Estadística). Data were disaggregated by sex-groups and five-year age groups. Spatial distribution of smoothed municipal relative risks (RR) of bladder cancer was carried out using a Besag, York and Mollié model. Bayesian model were used to calculate the posterior probability (PP) of RR greater than one. RESULTS: 1.573 cases were included. Incidence rates standardized to European population increased among men from 20,8/100.000 (1996-98) to 33,1/100.000 (2006-2008) and among women these rates increased from 1,9/100.000 to 5,9/100.000 for the same period of time. No relevant differences were found in the municipal distribution of the incidences. CONCLUSIONS: bladder cancer incidence rates are high in the European context. Rising trends in incidence in both sexs, particularly in women are observed.

["Post micturition residual; urodynamic"]. / <>

OBJECTIVES: To study the possible correlation between the existence of postmicturition residual (PR), both in men as in women, with other urodynamic parameters. MATERIAL AND METHODS: A retrospective study in a series of 121 patients (33 male, 88 female), age X=68.22 and SD=12.904 (16-90 years), with a significative PR had been underwent a videourodynamic study. All cases of neurogenic vesicourethral dysfunctions and post pelvic radiotherapy were excluded. Statistical study was performed between the PR and the presence of urinary symptoms, urodynamic data, and findings of physical examination. The study was conducted, both descriptive and with statistical correlations. We used the Spearman Rho and compared with the median chi-square. RESULTS: We found a positive correlation (men and women), between the PR and bladder capacity (p=0.001) and between the PR free flowmetry and PR test pdet/flow (r=0.450 p=0.001). In women, a positive correlation was found between the PR and the urethral resistance (URA) (p=0.001), and between PR and voiding by abdominal pressure (p<0,05). We found a negative correlation in men between the PR and the parameters of detrusor contraction (W80-W20) (p<0.05). Not found statistically significant correlation between the PR and cystometry, nor with the urodynamic diagnosis of obstruction, associated radiological semiology, hyperactive bladder and emptying symptoms in men. CONCLUSIONS: The PR behaved more as a parameter measurement of detrusor contractility, than a parameter of the lower urinary tract obstruction. The PR was not associated with any clinic or associated radiologic semiology.
