Chapter 76 / Urology 751

What is the treatment

 

according to stage:

 

Stage 0?

TURB and intravesical chemotherapy

Stage I?

TURB

Stages II and III?

Radical cystectomy, lymph node

 

dissection, removal of prostate/uterus/

 

ovaries/anterior vaginal wall, and urinary

 

diversion (e.g., ileal conduit) chemo

Stage IV?

What are the indications for a partial cystectomy?

What is TURB?

If after a TURB the tumor recurs, then what?

What is and how does bacillus Calmette-Guérin work?

PROSTATE CANCER

Cystectomy and systemic chemotherapy

Superficial, isolated tumor, apical with 3-cm margin from any orifices

TransUrethral Resection of the Bladder

Repeat TURB and intravesical chemotherapy (mitomycin C) or bacillus Calmette-Guérin

Attenuated TB vaccine—thought to work by immune response

What is the incidence?

Most common GU cancer ( 100,000

 

new cases per year in the United States);

 

most common carcinoma in men in the

 

U.S.; second most common cause of death

 

in men in the U.S.

What is the epidemiology?

“Disease of elderly men” present in

 

33% of men 70 to 79 years of age and in

 

66% of men 80 to 89 years of age at

 

autopsy; African American patients have

 

a 50% higher incidence than do white

 

patients

What is the histology?

Adenocarcinoma (95%)

752 Section III / Subspecialty Surgery

 

What are the symptoms?

Often asymptomatic; usually presents

 

as a nodule found on routine rectal

 

examination; in 70% of cases, cancer

 

begins in the periphery of the gland

 

and moves centrally; thus, obstructive

 

symptoms occur late

What percentage of patients

40% of patients have metastatic disease

have metastasis at diagnosis?

at presentation, with symptoms of bone

 

pain and weight loss

What are the common sites

Osteoblastic bony lesions, lung, liver,

of metastasis?

adrenal

What provides lymphatic

Obturator and hypogastric nodes

drainage?

 

What is the significance of

Spinal cord venous plexus; route of

Batson’s plexus?

isolated skull/brain metastasis

What are the steps in early

1. Prostate-specific antigen (PSA)—most

detection?

sensitive and specific marker

 

2. Digital rectal examination (DRE)

When should men get a

Controversial:

PSA-level check?

1. All men 50 years old

 

2. 40 years old if first-degree family

 

history or African American patient

What percentage of patients

60%

with prostate cancer will

 

have an elevated PSA?

 

What is the imaging test for bladder cancer?

How is the diagnosis made?

What is the Gleason score?

What are the indications for transrectal biopsy with normal rectal examination?

TransRectal UltraSound (TRUS)

Transrectal biopsy

Histologic grades 2–10:

Low score well differentiated High score poorly differentiated

PSA 10 or abnormal transrectal ultrasound

 

Chapter 76 / Urology 753

Staging (AJCC):

 

Stage I?

Tumor involves 50% of 1 lobe, no nodes,

 

no metastases, PSA 10, Gleason 6

Stage II?

Tumor within prostate; lobe 50% but

 

PSA 10, or Gleason 6; or 50% of

 

1 lobe, no nodes, no metastases

Stage III?

Tumor through prostate capsule or into

 

seminal vesicles, no nodes, no metastases

Stage IV?

Tumor extends into adjacent structures

 

(other than seminal vesicles) or nodes

 

or metastases

What does a “radical prostatectomy” remove?

What is “androgen ablation” therapy?

How do LHRH agonists work?

What are the generalized treatment options according to stage:

Stage I?

Stage II?

Stage III?

Stage IV?

What is the medical treatment for systemic metastatic disease?

1.Prostate gland

2.Seminal vesicles

3.Ampullae of the vasa deferentia

1.Bilateral orchiectomy or

2.Luteinizing Hormone-Releasing Hormone (LHRH) agonists

Decrease LH release from pituitary, which then decreases testosterone production in the testes

Radical prostatectomy

Radical prostatectomy, lymph node dissection

Radiation therapy, androgen ablation

Androgen ablation, radiation therapy

Androgen ablation

754 Section III / Subspecialty Surgery

 

What is the option for

XRT

treatment in the early stage

 

prostate cancer patient 70

 

years old with comorbidity?

 

BENIGN PROSTATIC HYPERPLASIA

What is it also known as?

What is it?

What is the size of a normal prostate?

Where does BPH occur?

What are the symptoms?

How is the diagnosis made?

What lab tests should be performed?

What is the differential diagnosis?

What are the treatment options?

BPH

Disease of elderly men (average age is 60 to 65 years); prostate gradually enlarges, creating symptoms of urinary outflow obstruction

20 to 25 gm

Periurethrally

(Note: prostate cancer occurs in the periphery of the gland)

Obstructive-type symptoms: hesitancy, weak stream, nocturia, intermittency, UTI, urinary retention

History, DRE, elevated PostVoid Residual (PVR), urinalysis, cystoscopy, U/S

Urinalysis, PSA, BUN, CR

Prostate cancer (e.g., nodular)—biopsy Neurogenic bladder—history of

neurologic disease

Acute prostatitis—hot, tender gland Urethral stricture—RUG, history of STD Stone

UTI

Pharmacologic— -1 blockade Hormonal—antiandrogens Surgical—TURP, TUIP, open prostate

resection

Transurethral balloon dilation
