Answer

More than 70% of all newly diagnosed bladder cancers are non–muscle invasive, approximately 50-70% are Ta, 20-30% are T1, and 10% are CIS. Approximately 25% of affected patients have muscle-invasive disease at diagnosis. Approximately 5% of patients present with metastatic disease, which commonly involves the lymph nodes, lung, liver, bone, and central nervous system. 

In order to clinically stage a patient with muscle-invasive bladder cancer the following needs to be completed: CT or MRI of the abdomen and pelvis, chest imaging, CBC, and chemistry panel with alkaline phosphatase. [80] Bone imaging is recommended only if there is concern for bone metastasis, which could be indicated by bone pain or an elevated alkaline phosphatase. [1] Currently, routine PET scanning is not recommended during the initial staging workup. [80]
