In recent years, the arrival of targeted oral therapies has greatly changed cancer treatment. These therapies help patients stay independent by reducing the number of hospital visits, since the treatment is given at home. However, this way of giving treatment brings specific challenges, especially in managing side effects and making sure patients follow their treatment properly.

Because of this, many patient education programs have been created to help patients learn how to manage their treatment on their own. Although only a few studies have formally looked at how useful these programs are, the available information suggests that they help patients handle side effects better and follow their treatment more closely.

Neuroendocrine tumors are a diverse group of tumors that are becoming more common. More patients with these tumors are now treated with targeted oral therapies such as everolimus, sunitinib, cabozantinib, or chemotherapy with temozolomide and capecitabine.

These treatments are often given together with a patient education program. However, so far, no study has specifically looked at how helpful these education programs are for this group of patients.

Inclusion Criteria:

• Adult patient (>18 years) at the time of the study
• Patient diagnosed with a neuroendocrine tumor (NET) with an indication for treatment with oral anti-tumor agents (everolimus, sunitinib, cabozantinib, temozolomide +/- capecitabine, others including lenvatinib)
• Collection of the patient's non-opposition to participate in the study

Exclusion Criteria:

• Minors
• Pregnant, parturient, or breastfeeding women
• Persons deprived of liberty by judicial or administrative decision
• Adults under legal protection measures (guardianship, conservatorship)
• Refusal to participate in the study

Recruitment will be carried out among patients hospitalized in the Medical Oncology department at Edouard Herriot University Hospital.

Every consecutive patient with an indication for oral anti-tumor agents (ATO) within the context of a neuroendocrine tumor (NET) will be screened and included in the study in the absence of contraindications and after obtaining their non-opposition.
