Long term experiences after coming off Opdivo/Nivolumab

Hi all- my grandma was diagnosed with stage 3 gastroesophageal junction cancer in June last year. She is no evidence of disease post chemo, radiation, and surgery (November 2024), and is currently in month 9 or 10 out of 13 taking adjuvant Opdivo infusions.

Just hoping for some personal experiences of how people do after coming off this drug-as obviously we are nervous for her infusions to end after this being what has kept her cancer free these past months.

Thanks!
