Prostatic and Bladder Cancer Flashcards
What is the apex of the prostate continuous with?
striated spincter
What is the base of the prostate continuous with?
bladder neck
What is the ejacultory duct?
union of seminal vesicles and vas deferens
What is the verumontanum?
elevation in the prostatic urethra where the ejacultory ducts drain
What is the transitional zone of the prostate?
surrounds the prostatic urethra proximal to the verumontanum which gives rise to BPH
What is the central zone of the prostate?
cone shaped region that surround the ejaculatory ducts
What is the peripheral zone of hte prostate?
posteriolateral prostate- majority of prostatic glandular tissue
Where does the majority of prostate adenocarcinoma arise from?
peripheral zone
What ethnicity has the greatest risk of prostate cancer?
black men
How are most prostatic cancers picked up?
PSA tests and abnormal DRE findings
What is found on DRE with prostate cancer?
asymmetry; nodule; fixed craggy mass
What is prostate specific antigen?
a glycoprotein enzyme produced by the secretory epithelial cells of the prostate
What is the function of PSA?
liquefaction of semen
What can elevate PSA aside from prostate cancer?
BPH; prostatitis/UTI; retention; catheterization; DRE
What are teh indications for trans-rectal USS guided prostate biopsy?
men with abnormal DRE or eleated PSA
What are the complications of TRUS?
sepsis; rectal bleeding; haematospermia and haematuria
What type of cancer are the majority of prostate cancers?
multifocal adenocarcinomas
What is the pattern of growth with prostate cancer?
local extension through the prostatic capsule, to the urethra, bladder base and seminal vedicals with perineural invasion along autonomic nerves
Where are the most common sites for mets with prostate cancer?
pelvic lymph nodes and the skeleton
What is the Gleason’s score system?
based on the architectural appearance rather than cytological features of CaP
What increases the Gleason score?
loss of the glandular structure and replacement by a disorganised malignant cell growth pattern
Why is Gleason’s score used?
a very good predictor of prognosis
What is the T3 PaC?
tumour has extended through the prostatic capsule
What are the complications of radical prostatectomy?
erectile dysfucntion; incontinence; bladder neck stenosis
