In patients with locally advanced muscle-invasive bladder cancer, neo-adjuv
ant chemotherapy was designed to treat micrometastatic disease present in u
p to 50% of patients at the time of diagnosis. Early chemotherapy has been
combined with local therapy based on the reasoning that treatment of small
volume disease would result in a better outcome. Another reason for giving
neo-adjuvant chemotherapy is in an attempt to save the bladder. In selected
patients, bladder preservation can be achieved with the use of chemotherap
y plus radiotherapy, partial cystectomy, or transurethral resection of the
bladder (TURB). Neo-adjuvant chemotherapy and bladder preservation remain c
ontroversial topics, as radical cystectomy is still considered to be the go
ld standard of treatment for muscle-invasive bladder cancer. The true succe
ss of bladder-preserving treatment by chemotherapy with or without RT will
require validation in prospective randomized trials.
