Carcinoma of the bladder (CaB) is a common tumor of the genitourinary
tract. In the United States in 1997, CaB was second in frequency of oc
currence and third in mortality among genitourinary tumors. This tumor
has a well-documented history of environmental and industrial causati
ve factors. The strongest etiologic risk factors include the use of to
bacco, which is thought to be responsible for half of the CaB diagnose
d in men in the United States, and some arylamines. In the past 30 yea
rs, there has been major improvement in the survival of patients with
this disease. Multiple factors were responsible for this accomplishmen
t and they include: 1) better understanding of the natural history of
CaB, 2) development of immunohistochemical analysis helpful in definin
g prognostic factors, 3) improved imaging and nonimaging diagnostic mo
dalities helpful in making earlier diagnosis and better defining the t
rue anatomical extent of the tumor, 4) development of more effective t
herapy for carcinoma in situ, 5) major improvement in surgical techniq
ues resulting in better treatment outcomes, and 6) the wide use of adj
uvant chemotherapy. Major stress has been placed on the quality of lif
e of patients treated for CaB. Quality of life was improved by optimiz
ing surgical, radiation, and medical treatment techniques. The two mos
t important factors producing this quality-of-life improvement include
: 1) the use of organ-preserving therapy in properly selected patients
that involves the use of a multimodality therapeutic approach with tr
ansurethral resection, radiation therapy, and chemotherapy; and 2) the
ability to treat selected men and women with radical cystectomy follo
wed by orthotopic reconstruction that allows patients-nearly physiolog
ic voiding. Current research efforts are directed toward better patien
t selection for appropriate therapy which is expected to increase pati
ent survival and improve quality of life. Of particular importance in
the selection of this optimal therapy in patients with CaB is a wide a
pplication in the clinical practice of important recent advances in mo
lecular genetics.
