Nowadays, more and more patients are receiving anticancer treatment by mouth. In this context, the development of oral chemotherapy represents a challenge to our health system as it means adapting the hospital's organization and making it safer to manage patients who are becoming autonomous and responsible for following their oral anti-cancer treatment at home.~According to the French National Cancer Institute, around 5,000 new cases of multiple myeloma (MM) are detected each year, and this figure is on the increase year by year. It is more common in people aged over 70. Patients treated have several risk factors for not respecting medication adherence such as age, polypharmacy related to the presence of other chronic pathologies, and associated comorbidities. Furthermore, the patterns of administering oral anticancer medication for multiple myeloma are complex.~In a previous study we designed a clinical pharmaceutical consultation guide with a view to improving patients' adherence to their oral anticancer treatment. This guide was designed and validated by a multidisciplinary workgroup to ensure that it was readable, understandable and easy to memorize for the patients being treated for multiple myeloma. The guide was designed so that the information given was reproducible from one patient to another, whoever the pharmacist might be, by standardizing the information given. Our hypothesis is that the guided consultation would make it possible to minimize the rate of discordance observed compared with the usual, standard type of management.~The main objective of this study is to evaluate the performance of the guided consultation (Intervention) by evaluating the rate of discrepancies observed compared with the theoretical therapeutic pattern prescribed, compared with a control group(standard management) for patients with multiple myeloma on their first cure of oral anticancer medication.~Secondary objectives are:~A. For both groups in the study, evaluate the patients' level of knowledge and understanding of their treatment.~B. In the interventional group, evaluate the acceptability of the intervention by the patient.~C. For both groups in the study, evaluate the attitude of the patients when faced with intercurrent events (foreseeable with oral anticancer treatment) for example : fever over 38.5°C, nosebleeds and /or bleeding gums, breathlessness, respiratory difficulties, chest pain, swelling, pain or redness in the legs, digestive difficulties, insomnia, fatigue, tingling, numb fingers or toes.~D. For both groups in the study, evaluate the adherence to treatment (adherence rate in percentages).~E. Evaluate the rate of discrepancies per item : treatment started in due time, right molecule taken at the right moment, respect of days when no medication is to be taken, day when treatment is to be stopped.

It is more common in people aged over 70. The patterns of oral anticancer medication for multiple myeloma are complex and these patients do not always follow their treatment correctly. A clinical pharmaceutical consultation guide was designed to overcome this problem.Our hypothesis is that the guided consultation would minimize the rate of discrepancies observed compared with the usual, standard type of management.~The main objective is therefore to evaluate the performance of this guided consultation (interventional group) in comparison with a control group (standard management) for patients with multiple myeloma on their first cure of oral anticancer medication.
