Anyone have success with immunotherapy for kidney cancer?

I had 19 Keytruda treatments over a two year period; because of my age I did not have removal of my kidney which had the malignant lesion, which urologist recommended. My last infusion was November last year. My last two ct scans which were done July last year and February this year were clear with no visible lesion and no cancer spread. I have another ct scan this week, and I hope it remains clear.

@colleenyoung Stage 4. 3 months immunotherapy. 4 months cabometyx

My third CT done this month shows no spread of cancer and malignant kidney lesion is still no longer visible on scan. That means the three scans done over a twelve month period have remained clear. I am confidant that the 19 Keytruda treatments I had which ended in November of last year had something to do with this. As I pointed out before, I opted out of having total nephrectomy done as urologist suggested be done when malignant tumor on left kidney was diagnosed in March of 2023. Keytruda and five high does radiation done in 2024 to stop bleeding were the only treatments I had.
