PFS is not always OS.
One of the biggest misconceptions in oncology is assuming that delaying progression automatically means patients live longer.
Many strategies consistently improve:
• PFS
• depth of response
• MRD negativity
…but OS often barely moves.
Examples:
• Upfront vs delayed AutoSCT
• Lenalidomide maintenance
• HD melphalan intensification
• Many maintenance strategies in lymphoma
Why?
Because:
• crossover therapies matter
• salvage therapies work
• toxicity matters
• resistant clones survive
• biology evolves
A longer remission is meaningful.
But it is not always a longer life.
The critical question is no longer:
“Did the curve separate?”
The question is:
“What happened to OS?”
