Abstract:
The scientific goal of phase I clinical trials in oncology is to determine and optimise the drug dose and schedule on the basis of the toxicity profile. These trials also respond to a need: they offer the chance of early access to a new therapy for cancer patients who are characterised by both the lack of a therapeutic option and a desire to fulfil personal ambitions. The therapeutic relationship in this context must reconcile unreasonable hopes and anxiety regarding death and follow the same rules as in other doctor-patient relationships, with the triple requirement being that it should be genuine, therapeutic and empathetic.

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...
