To determine the 'value' of PFS to patients with metastatic cancer:
- 1 . Patient understanding of therapeutic intent
- 2. Their goals and priorities
- 3.Trade-offs between burdens/toxicities/QoL and Survival (PFS and OS)
- 4. Patient characteristics that under-pin decusuons about treamtment options
- 5. Association of PFS improvement and/or deterioration with QoL and underlying mechanism
- 6. Association of PFS improvement and or deterioration of psychological well-being.
Progression Free Survival (PFS) is commonly used as an endpoint in clinical trials of novel cancer therapies. This study aims to find out what this means for patients. hat they understand about and expect from these treatments and if the benefits from the treatment controlling the cancer make it worth any side effects they could or do experience.
