PURPOSE There are few data regarding the epidemiology of hereditary or familial prostate cancer (PCa) in East Asians, especially in Korean men. Therefore, we evaluated the incidence of familial and hereditary PCa and the relation between socioeconomic status and the incidence of nonsporadic prostate cancer (NSPC). MATERIALS AND METHODS We collected data from all patients who were treated for ...

Prostate carcinoma is the most common non-cutaneous malignancy in men in developed countries and the incidence has been steadily rising in the developing countries. Active research in recent years has led to tremendous progress in our understanding of the biology and genetics, and marked improvement in diagnosis and treatment of prostate cancer. Gleason grading has remained as the cornerstone f...

OBJECTIVES To determine the risk of pelvic lymph node (LN) metastases at radical prostatectomy (RP) for Gleason score (GS) ≤7: 3 + 3 = 6 (grade group [GG]1); 3 + 4 = 7 (GG2); 3 + 4 = 7 (GG2) with tertiary pattern 5 (T5); 4 + 3 = 7 (GG3); 4 + 3 = 7 (GG3) with T5, using the 2014 modified Gleason grading system and the novel GG system. MATERIALS AND METHODS We searched our RP database to indenti...

UNLABELLED WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The Gleason scoring system is a well-established predictor of pathological stage and oncological outcomes for men with prostate cancer. Modifications throughout the last few decades - most recently by the International Society of Urological Pathology (ISUP) in 2005 - have attempted to improve the correlation between biopsy an...

The Gleason grading system is a standard method of assessing prostate cancer. Very little is known, however, about the person behind the system, Donald Floyd Gleason, MD, PhD. Our objective was to construct a biography of Gleason and show how his work advanced prostate cancer diagnosis. We reviewed Gleason's notes, letters, and publications with the Veteran's Administration Cooperative Urology ...

AbstractWith the development of computational pathology, deep learning methods for Gleason grading through whole slide images (WSIs) have excellent prospects. Since size WSIs is extremely large, image label usually contains only slide-level or limited pixel-level labels. The current mainstream approach adopts multi-instance to predict grades. However, some considering ignore labels containing r...

The Gleason system for prostate cancer was based on a study of 270 patients from the Minneapolis Veterans Administration Hospital in 1966-1967. In 1974, Gleason and the Veterans Administrative Cooperative Urological Research Group expanded this study to 1032 men. These studies formed the basis of the Gleason grading system, which is now endorsed as the primary grading system for prostate cancer...

We compared the predictive ability of the 2014 and 2005 Gleason grading systems in 568 patients initially diagnosed with metastatic prostate cancer (PCa). Outcomes included the duration of castration-resistant prostate cancer-free survival (CFS) and overall survival (OS). Univariate analyses and log-rank tests were used to identify prognosis indicators and assess univariable differences in CFS ...
