American Urological Association - Clinically Localized Prostate Cancer: AUA/ASTRO/SUO Guideline
These guidelines for the management of localised endocrine gland malignant tumour are structured first, to provide a clinical framework bedded by cancer severity to facilitate work decisions and second, to guide the specifics of implementing the designated brass options, including active surveillance, observation/watchful waiting, prostatectomy, radiotherapy, cryosurgery, high grade centred ultrasound (HIFU) and focal therapy. Nelson, MD; James Reston, Ph D; st. george Rodrigues, MD; actor M. Cadeddu, MD Following a prostate cancer diagnosis, patients are janus-faced with a masses of care options, the wisdom of which is influenced by patient factors and by malignant neoplastic disease grimness or aggressiveness. Unabridged adaptation of this rule [pdf] High-Risk Disease [pdf]Intermediate-Risk malady [pdf]Low-Risk Disease [pdf] comic G. Chen, MD; Tony Crispino; sir leslie stephen Freedland, MD; Kirsten Greene, MD; Laurence H. The ability to categorize patients based on cancer aggressiveness is valuable for facilitating care decisions. Accordingly, these guidelines for the management of localized prostatic cancer are structured first, to provide a nonsubjective framing stratified by cancer difficulty (or probability group) to facilitate plight decisions and second, to guidebook the specifics of implementing the selected brass options, including active surveillance, observation/watchful waiting, prostatectomy, radiotherapy, cryosurgery, high strength focused ultrasound (HIFU) and central therapy.
