A 68-year-old man diagnosed with undifferentiated bladder carcinoma underwent radical cystectomy in another hospital. His clinical staging was T3bN2M0. Four months after the operation, he had right axilla lymph node swelling and pain. He was referred to our hospital, and diagnosed with axilla lymph node metastasis of bladder carcinoma based on test results. Four cycles of GEM and CDDP chemotherapy were performed. After the chemotherapy, the metastatic focus disappeared completely from the CT scan, and the case was considered to be CR. It is suggested that this combination therapy may be useful for bladder carcinoma in advanced or metastatic stages.
