This is an open-label, single-centre, category 2 "Jardé Law" proof-of-concept study designed to demonstrate the feasibility of a decentralised care pathway for patients with cancer or haematological malignancies receiving oral treatment.

The study will be conducted on a population of 33 patients.

In current practice, patients with certain solid cancers or haematological malignancies may be prescribed oral chemotherapy on a retroceded basis. In these cases, the oncologist (coordinating investigator) sees the patient for a consultation every 3 cycles to prescribe/renew the treatment for approximately 3 months. Every month, the patient returns to the centre to have the treatment dispensed by the hospital pharmacy. No medical consultation is associated with this visit.

In this study, it is proposed to decentralise the delivery of treatment to these patients by introducing two visits to the patient's home by a service-providing nurse.

The decentralised patient pathway will be organised and monitored by the Advanced Practice Nurse (APN) at the investigating centre, who will be responsible in particular for coordination with the service-providing nurse and the hospital pharmacy.

Inclusion Criteria:

1. Patient over 18.
2. A patient with solid cancer or haematological malignancy receiving oral retroceded therapy as part of standard management.
3. Patient with a performance index (ECOG): 0-2.
4. Patient contactable by telephone for follow-up by the Advanced Practice Nurse.
5. Patient willing to make two home visits within 6 months of inclusion.

Exclusion Criteria:

1. Pregnant or breast-feeding patient.
2. Any psychological, family, geographical or social condition which, in the judgement of the oncologist, could potentially prevent the collection of informed consent or hinder compliance with the study protocol.
3. Patients deprived of their liberty by administrative or legal decision, or patients under guardianship.
