None:
A treatment's time toxicity (measured using contact days) can decrease days spent at home (home days). We evaluated the minimum clinically important difference (MCID) and non-inferiority margin (NIM) of home days, and treatment acceptance when all additional survival time was spent in health care by surveying people with lived (patients, n = 42; informal care partners, n = 29) and professional (oncologists, n = 8) experience of advanced cancer. All 3 groups reported similar MCIDs and NIMs (6-month survival; median MCID range, 14-15; P = .79; median NIM range, 5-11; P = .14). Care partners (48%) and patients (21%) more often accepted 2-week survival gains without an increase in home days than oncologists (0%), P = .09. Caregivers reported altruism guided their responses, and clinicians' responses in stated-preference work may differ from revealed-preferences in the clinic. By empirically deriving MCID/NIM for home days and evaluating treatment acceptance, this work will aid trial design and decision studies using an endpoint of home days.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
