cutaneous toxicity was the most common adverse event,
followed by toxicities related to the gastrointestinal tract.
In the younger age group, the most common adverse
event was endocrine dysfunction, whereas skin toxicity
was the predominant adverse event in the older age
group.
4. Discussion
The analysis conducted in our study was meticulously
compared with recent updates from the CM-238 and
KN-054 clinical studies.
At the 24-month mark in our cohort, the OS, RFS, and
DMFS were 94%, 73%, and 73%, respectively. These figures
