Synopsis

Transitional cell carcinoma is a malignant tumor that originates from the cells of the transitional epithelium within the genitourinary tract, usually in the bladder lining. Accounts for 90% of bladder cancer cases. Less frequently arises in the ureter, urethra, or renal pelvis. In rare instances, can involve ovarian or respiratory transitional cells. Subtypes include muscle-invasive, non-muscle-invasive, and metastatic. Tumors are graded based on the amount of cellular differentiation noted on the specimen and range from grade T1-T4; they are classified as low-grade or high-grade. More common in older men, risk factors include smoking and exposure to occupational and industrial chemicals. Characterized by microscopic or gross hematuria and urinary dysfunction. Signs and symptoms include dysuria, urinary frequency, urgency, incontinence, nocturia, flank pain, and bone pain.

Management includes transurethral resection of bladder tumor, chemotherapy, neoadjuvant chemotherapy, radiation therapy, cystectomy, and radical cystectomy.
