Prostate Cancer
Definition
Risk Factors
Clinical Presentation
Diagnostics
Definition
- Malignancy arising from the bladder urothelium
- Most common type is urothelial carcinoma
- Often presents with painless hematuria
Risk Factors
- Cigarette smoking
- Occupational chemical exposures such as dyes and rubber
- Chronic bladder irritation or infection
- Cyclophosphamide therapy (chemotherapy agent)
Clinical Presentation
- Painless gross hematuria is classic
- Irritative voiding symptoms such as frequency or urgency
- Flank pain if obstruction occurs
- The question stem would likely describe an older smoker with painless blood in the urine
Diagnostics
- Urinalysis: hematuria
- Urine cytology: may detect malignant cells
- Cystoscopy with biopsy: diagnostic test of choice
- CT urography or renal ultrasound: evaluate upper tracts for masses or obstruction
Treatment
- Transurethral resection of bladder tumor for diagnosis and initial management
- Urology referral for cystoscopy
- Advanced disease may require more extensive surgery or systemic therapy
- Ongoing surveillance cystoscopy due to high recurrence
Exam Keys
- Painless hematuria in older patient = bladder cancer
- Smoking is strongest risk factor
- Cystoscopy with biopsy is required for diagnosis
- High recurrence rate requires surveillance
Penile Cancer
Definition
- Malignancy of the penis, usually squamous cell carcinoma
- Rare in the United States
Risk Factors
- HPV infection
- Lack of circumcision with chronic smegma accumulation
- Phimosis
- Smoking
- Poor hygiene
Clinical Presentation
- Painless penile mass, ulcer, or lesion
- May bleed or become foul smelling
- Inguinal lymphadenopathy in advanced cases
- The question stem would likely describe an uncircumcised man with a persistent penile lesion or ulcer
Diagnostics
- Clinical exam and biopsy of the lesion
- HPV testing may be supportive but not required
- Imaging (CT or MRI) if concerned for nodal or metastatic spread
Treatment
- Surgical excision is mainstay
- Topical or laser therapy for very superficial lesions
- Partial or total penectomy for invasive disease
- Radiation or chemotherapy for advanced or metastatic cases
Exam Keys
- Uncircumcised male with chronic lesion = think penile cancer
- Strongly associated with HPV and poor hygiene
- Diagnosis requires biopsy
- Treatment is surgical excision
Prostate Cancer
Definition
- Malignancy of prostate gland, usually adenocarcinoma
- Most common non-skin cancer in men
- Often slow growing and asymptomatic early
Risk Factors
- Age over 50
- African American race
- Family history
- BRCA mutations
Clinical Presentation
- Often asymptomatic
- May have urinary hesitancy, weak stream, or nocturia
- Bone pain suggests metastasis
- The question stem would likely describe an older man with urinary obstructive symptoms or elevated PSA
