Female Urethral Cancer

Urethral cancer is a rare malignant tumor of the urethra, which most commonly occurs in women over 70 years (Amin and Young, 1997) (Krieg and Hoffman, 1999) (Rajan et al, 1993).

Epidemiology

Seldom, annual incidence of 1.5 per million population.

Etiology of Urethral Carcinoma

Risk factors include chronic inflammation or infection, diverticula, caruncle, papillomas, adenomas, leukoplakia and bladder cancer.

Pathology of Urethral Carcinoma

Histology:

Metastasis:

Urethral cancer of the distal urethra spreads into the inguinal lymph nodes, tumors of the proximal urethra spread in the pelvic lymph nodes. The lymph node drainage is variable. Hematogenous metastases occur relatively late in squamous cell carcinomas, in contrast to transitional cell cancer.

Tumor stage according to TNM

T:

Local tumor stage.

N:

Lymph node metastases.

M:

Distant metastases.

G:

Grading.

Signs and Symptoms of Urethral Carcinoma

Urethral bleeding, dysuria, frequency, urinary retention, palpable tumor or induration on pelvic examination.

Diagnostic Work-Up

Treatment of Female Urethral Cancer

Local excision or resection:

Suitable for well-differentiated non-invasive urethral tumors.

Anterior exenteration with complete urethrectomy:

Radical cystectomy with urethrectomy and resection of the anterior vaginal wall are treatment options for invasive tumors. Pelvic lymphadenectomy is done in the same way as in bladder cancer. If an invasive tumor of the distal urethra is present, inguinal lymphadenectomy is also recommended. Only heterotopic urinary diversion is possible. Some authors advocate for adjuvant radiotherapy.
