External validation of the Gleason grade group system in Argentinian patients that underwent surgery for prostate cancer.

Introduction: The aim of this article was to evaluate the effectiveness of the Gleason grade groups (GGG) system on a group of Argentinian patients with prostate cancer (PC) who underwent radical prostatectomy (RP).

Material And Methods: We retrospectively studied 262 patients who underwent RP between 1996 and 2014. To determine the performance and validity of the GGG system, a Kaplan-Meier analysis and multivariate analysis with Cox proportional method were performed to evaluate biochemical recurrence, distance metastases and specific cancer mortality.

Evaluation of microvascular invasion as a prognostic factor in the progression of non-metastatic renal cancer.

Introduction: The aim of this study was to describe the prognostic impact of microvascular invasion (MVI) in patients with non-metastatic renal cell cancer.

Material And Methods: We carried out a retrospective, descriptive and analytical study of patients with non-metastatic renal cell carcinoma who had undergone a radical or partial nephrectomy. Patients were divided according to the presence of MVI.

[Impact of tumor diameter on prognosis in patients with renal cancer stage pT3a.].

Objective: To determine the prognostic impact that tumor size has in patients with pathological renal cancer stage pT3a.

Methods: Retrospective, descriptive study evaluating 261 patients diagnosed with renal cancer pathological stage pT1-3aN0M0 between 1995 and 2013. Clinical and pathological characteristics were evaluated in each group.

[Is CAPRA-S score a valid tool in our environment to predict biochemical recurrence, metastasis and death after radical prostatectomy?].

Objectives: To perform an external validation of CAPRA-S Score to determine prediction of biochemical recurrence, metastasis and death by PCa after RP in Argentinian population.

Methods: 216 patients were studied. The probability of the score to predict biochemical recurrence after RP was analyzed by the Cox proportional method.

[Predictive score of success adapted to our environment to improve results of extracorporeal lithotripsy].

Objective: To present a predictive tool of success of ESWL adapted to our environment.

Methods: We performed a retrospective, descriptive and analytical study of patients with renal and upper ureteral stones whom underwent ESWL with DUET MAGNA lithotripter between January 2014 and March 2015. We included 114 patients in whom demographics and CT scan characteristics were studied.
