Metastatic Urinary Bladder Carcinoma on Palliative Chemotherapy Showing Rapid Progression on Interim Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

Bladder cancer (BC) is among the top ten most common cancer types globally. Muscle invasive BC has a high incidence of metastasis. Metastatic BC has a poor prognosis and limited treatment options. Here, we present a middle-aged man with oligometastatic BC, which was treated with palliative chemotherapy. He had significant clinical improvement. However, interim 18F-Fluorodeoxyglucose positron emission tomography/computed tomography demonstrates a rapid disease progression extensive metastasis.
