What happens after staying clear on NMIBC cystoscopies post-GEMDOCE?

I had NMIBC diagnosed in January 2025. I had two surgeries to remove the cancer, followed by six weeks of GEMDOCE (gemcitabine followed by docetaxel) held in the bladder for 90 minutes each. I had a series of six treatments, weekly, then one year of the same, replaced by a cystoscopy in September and one upcoming this July. I was clear from the surgery, and cystoscopies have shown that I remain clear. Aside from the typical stressors, I found that the GEMDOCE treatment surprisingly gave me many post treatment symptoms, such as “chemo brain”, catching things that are “going around”, and fatigue. I also noticed a reduction in skin collagen and skin sensitivity to cosmetics. I have my next cystoscopy in July. I have stayed clear so far, and hope to be clear at this cystoscopy. I am not sure what happens next if I am clear, or if I am not.
