Prevalence of infiltrating bladder cancer in surgical series 80-90%(Kaye & Lange, 1982) (Hopkins et al, 1983) 57%(Vaidya et al, 2001)

(A) Recurrence-free survival and (B) overall survival in 1,054 patients after radical cystectomy stratified by pathologic subgroups (organ confined, extravesical, and lymph node positive. Stein JP et al, 2001

Neoadjuvant chemotherapy PROS  Early control of micrometastasis   local control (bladder sparing)  Better compliance to CT (  acute toxicity and lethality)  Chemosensitivity (postcystectomy treatment)  Prognostic significance of T response CONTRA  Delay in local control  Understaging? (postcystectomy treatment)  Overtreatment for a definite proportion of patients (patients selection)

Why adjuvant chemotherapy? 1.Pathologic staging most accurately predicts the risk of relapse 2.The risk for new tumor formation is reduced or eliminated after surgery 3.No delay in surgery
