Harold J. Burstein, Breast cancer specialist and professor at Dana Farber Cancer Institute, shared a post by Tom Powles on X, adding:
“These type of actual data on treatments are interesting and raise important questions about ‘getting to 2nd line therapy.’
But they beg the Question: If PS/tumor are so ‘bad’ that patient cannot get to 2L, what are data that 2L Rx would work? Most cases like that excluded from trials.”
Quoting Tom Powles post:
“During the period of PD-1 inhibition availability for RCC in the UK only 60% of patients with progressive renal cancers (n>1000) received ICI therapy(1st-3rd line).
This occurred across IMDC risk groups.
Assuming all patients will eventually receive ICI is not supported by data.”
