Term
what is the risk for prostate CA in white men and black men?
Definition
white: 1 in 6, black: 1 in 5. prostate CA is also simply more aggressive in black pts.
Term
why is it more rare for its to have symptoms such as urinary retention/back+leg pain/hematuria w/prostate CA in 2010?
Definition
b/c of PSA, pts do not usually progress to these symptoms before being diagnosed/treated
Term
what is the etiology of prostate CA?
Definition
environmental factors have not been determined. there is a strong familial predisposition (presents 6-7 yrs earlier) involving the HPC1 and PCAP gene on chromosome 1
Term
what are the screening recommendations for prostate CA?
Definition
PSA test @ 50 for white pts w/no risk factors, and PSA test @ 40 for black pts w/no risk factors.
Term
what is the absolute normal PSA level?
Definition
< 4.0 ng/mL
Term
when is free PSA used to dx?
Definition
to cross-check against a negative bx. if the bx was negative, but the free PSA is <20%, there is a higher probability of prostate CA and another bx should be performed
Term
what is PSA velocity?
Definition
how fast the PSA level is changing, >0.75 change in a year is worrisome - but not diagnostic
Term
what does PSA density refer to?
Definition
the ratio of PSA/gland size; >0.15 is worrisome
Term
if there is an abnormality of PSA/DRE, what is the next step?
Definition
US guided prostate bx reviewed by a pathologist
Term
what is the gleason grading system?
Definition
the two most common cell patterns from several prostate CA bx's are graded 1-5 and then added together. <3 do well, >8 don't do well, etc
Term
why is tx of prostate CA sometimes more difficult than kidney or bladder?
Definition
b/c there are several good tx choices, and the pt ultimately has to decide what they want
Term
what is watchful waiting and active surveillance?
Definition
watchful waiting: for older pts diagnosed w/prostate CA who are likely to die of something else first. active surveillance: postponing tx in a younger healthy pt (~50) w/low risk prostate CA while continuing to run PSAs/get bx's to maintain good quality of life for as long as possible until the disease progresses to the point where tx is deemed necessary (need a compliant pt).
Term
what are radiation therapy options for prostate CA?
Definition
external beam radiation therapy, brachytherapy (radioactive seeds), and high dose brachytherapy
Term
who is cryotherapy good for?
Definition
prostate CA pts who have failed radiation therapy - but doesn’t usually work as well as surgery or radiation & side effects are as bad, if not worse
Term
what characterizes the radical prostatectomy options?
Definition
open sx (older way), conventional laparoscopic sx, and robotic-assisted laparoscopic sx (better b/c better visualization, minimally invasive, less pain, faster recovery, less bleeding (watertight anastamosis), shorter catheter time, shorter length of hospital stay, and smaller incision)
Term
who gets renal cell CA (RCC) more commonly, M or F? why is there a 100% increased incidence since 1970? how lethal is RCC?
Definition
males get RCC more commonly, there is a 100% increased incidence since 1970 b/c of imaging technology, and it RCC is the most lethal of all GU malignancies (40% mortality rate vs. 20% w/ bladder and prostate)
Term
*exam question: what is the most common cause of RCC?* other etiologic agents?
Definition
*tobacco* other etiologic agents: high fat/protein diet (obesity), coffee, occupational exposure, iatrogenic radiation, and familial factors (von hippel-lindau disease and hereditary papillary RCC)
Term
what is the classic triad associated with RCC?
Definition
hematuria, flank pain, and palpable mass in flank/abdomen. *this is only seen 10% of the time in clinical practice, so this is more board-related information*
Term
how do RCC pts present?
Definition
most RCC pts are asymptomatic and are diagnosed incidentally (even though 25% are metastatic. commonly seen signs/symptoms: wt loss, fever, HTN, hypercalcemia, night sweats, malaise, and varicocele (esp if on R side b/c L is more common)
Term
what is paraneoplastic syndrome associated w/RCC?
Definition
hypercalcemia, erythrocytosis, nonmetastatic hepatic dysfunction (stouffer syndrome - elevated LFTs that go away when RCC is removed), anemia, fever, cachexia, wt loss, increased ESR, and HTN
Term
how is RCC diagnosed?
Definition
CT/MRI (need to show active CA w/contrast enhancement to differentiate it from other renal masses) and surgical removal (radical nephrectomy). bx is usually not done due to risk of increased metastasis, needle track seeding, and *bleeding*.
Term
what is the most common RCC?
Definition
clear cell (70-80%), followed by papillary, chromophobic, collecting duct, and medullary (last 3 are rare, but aggressive). any of these can be a sarcomatoid variant, which means it will be more aggressive.
Term
do radiation/chemo work for RCC? what characterizes sx for RCC?
Definition
no, sx is the best option - laparoscopic radical nephrectomy is the gold standard. nephron-sparing sx such as partial nephrectomy is better if possible, but it is difficult. ablative sx techniques: RFA (radiofrequency ablation) burns it or cryosx freezes it (*better for kidney then prostate CA, easiest modality)
Term
what is the 2nd most common urologic tumor?
Definition
bladder CA
Term
who is bladder CA more common in?
Definition
white males - however bladder CA is more aggressive if blacks or women have it
Term
what is the most common cause of bladder CA? other risk factors?
Definition
smoking. other risk factors: industrial exposure, prior pelvic radiation, and long-term indwelling catheters.
Term
what is cyclophosphamide?
Definition
a chemotherapy agent which has a breakdown product: acrolein that increases bladder CA risk, however if mesna is coadministered this risk should be negated
Term
how does bladder CA present?
Definition
most common: *painless gross hematuria. also: irritative bladder symptoms (dysuria, frequency, urgency), bony/pelvic pain, and flank pain
Term
what does evaluation of hematuria consist of?
Definition
UA, urine cx, +/- cytology, upper tract imaging (CT/MRI +/- contrast), and cystoscopy
Term
how is bladder CA diagnosed/staged?
Definition
transurethral resection (same as TURP for prostate CA) -> goal is to get muscle
Term
*exam question: what is the most common type of bladder CA in the US?*
Definition
*transitional cell carcinoma* followed by SCC (most common *globally), and more rarely, adenocarcinoma (suspect metastasis).
Term
what is bladder SCC associated with?
Definition
in the US: persistent inflammation, as seen w/bladder stones/foley catheter. in underdeveloped countries ("walking barefoot by the nile"): schistosomiasis.
Term
what is the difference between superficial and muscle invasive bladder CA?
Definition
superficial bladder CA (Ta/T1) sits on, but not in the lamina propria - they will recur 75% of the time but they are not lethal unless they progress to muscle invasive type (25% occurrence). muscle invasive bladder CA invades muscle/fat and can be lethal.
Term
what is tx for superficial bladder CA?
Definition
scrape out tumor, r/o muscle involvement, f/u w/surveillance therapy. intravesical therapy can be used for more aggressive tumors, the most common type of which is BCG a live TB strain.
Term
what is tx for muscle invasive bladder CA?
Definition
either sx (radical cystectomy: M - remove bladder/prostate, F - remove basically everything in the pelvis) or chemo+radiation (bladder preserving tx: gemcitabine/cisplatin).
Term
what characterizes urothelial tumors of the renal pelvis/ureter?
Definition
basically the same thing as bladder CA, but higher up. etiology: *smoking (esp upper tract TCC). cell types: TCC (90%), SCC (1-7%) and adenocarcinoma.
Term
what is the most common location of urothelial CA?
Definition
renal pelvis (58%) then the ureter
Term
what are symptoms of urothelial CA of the renal pelvis/ureter?
Definition
gross/microscopic hematuria (75%), flank pain (not as common b/c slowly progressive), dysuria, and advanced disease (wt loss/anorexia/flank mass/bone pain).
Term
how is urothelial CA of the renal pelvis/ureter diagnosed?
Definition
CT/MRI (hematuria evaluation), cystoscopy/retrograde pyelogram, and ureteroscopy w/bx
Term
*exam question: what is the the goblet sign?*
Definition
*dye filling up around the base of a tumor in a retrograde pyelogram at the top of the ureter* this indicates a need to perform a bx.
Term
what is treatment for urothelial CA of the renal pelvis/ureter?
Definition
nephroureterectomy (w/excision of bladder cuff): gold standard, TCC is treated more aggressively (remove kidney, entire ureter, part of bladder). nephron sparing sx does have a higher rate of recurrence, so it is only done if CA is just at the distal ureter. ureteroscopic tx: scope+laser, only really done in very sick pts or those w/superficial, low grade CA (higher risk of recurrence, requires more f/u)
Term
who is testicular CA seen in?
Definition
whites and in 3 modal peaks: infancy, age 25-40, and age >60. germ cell testicular CA is the most common solid tumor in men 15-35.
Term
what is the etiology of testicular CA?
Definition
pts w/cryptorchism: 10-40x higher risk
Term
what are the signs/symptoms of testicular CA?
Definition
painless testicular scrotal mass (most common), scrotal pain (less commone), gynecomastia (if hCG secreting - chorioCA), back pain, cough, and hemoptysis (last 3 - metastasis)
Term
how is testicular CA evaluated?
Definition
US, CXR, CT scan (chest, maybe head), and biomarkers (used to f/u primary therapy - AFP, beta-hCG, and LDH)
Term
what is the most common type of testicular CA?
Definition
germ cell, either seminoma or nonseminomatous (embryonal CA, teratoma, chorioCA, and yolk sac - treated differently)
Term
what is tx for testicular CA?
Definition
radical inguinal orchiectomy (need to keep lymph nodes+drainage separate). additional chemo/radiation depending on type/stage.
Term
how common is penile CA in the US?
Definition
very rare, esp in circumcised pts. there is an increase in incidence between 60-80 yr old and if pts do have this they have generally delayed dx/tx.
Term
what is the most common type of penile CA?
Definition
SCC (often under foreskin)
Term
how does penile CA present?
Definition
any non-healing lesion
Term
what is tx for penile CA?
Definition
sx (partial/total penectomy), chemo/radiation = not helpful
Term
what characterizes incidence of urethral CA?
Definition
very rare. SCC is the most common. more common in white females >60 yrs old.
Term
what is important in urethral CA pts?
Definition
make sure its not coming don from the bladder/prostate.
Term
how does a urethral CA pt present?
Definition
same as someone w/BPH
