How is tx of superficial tumors?

Chemotherapeutic agents and usually local treatment because metastasis are still controlled (risk of metastasis is still 5% so no need to any workup of metastasis= PET scan) T1 rarely causes metastasis, f/uEvery 3 months we do cystoscopy for the first 3 years. Then every 6 months till the 4th year Then one cystoscopy per year
