Follow-up of patients> 70 years old with cancer pathologies to evaluate the influence of geriatric factors associated with a review of therapies on their care pathways and health conditions. We will be particularly interested in the main objective, the unplanned hospitalization rate at 3 months in patients> 70 years old with cancer treated in oncogeriatric HDJ before the initiation of oncological treatment such as chemotherapy (oral or intravenous) and / or targeted therapy and / or immunotherapy and / or new generation hormone therapy.

The aging of the French population is associated with a constant increase in the number of cancers in people over 75 years of age (1/3 of cancers diagnosed in patients ≥ 75 years).

Oncogeriatrics is a combination of two specialties, oncology and geriatrics. This practice aims to ensure that all elderly cancer patients are treated according to their condition through a multidisciplinary and multiprofessional approach. The improvement of the care of elderly people with cancer has been measured in Measure 23.4 of the 2009-2013 Cancer Plan. This objective is pursued through action 2.16 of the 2014-2019 Cancer Plan aimed at meeting the specific needs of elderly people with cancer, notably by relying on the organizational set-up of UCOGs (Coordination Units in Onco-Geriatrics). for an improvement of the management practices of this population and a structuring of clinical research in oncogeriatrics.

However, 85% of people over 75 have at least one pathology and more than 7 different molecules are delivered on average at least three times a year. Polypharmacy is a factor of frailty and the risk of functional decline is established from two prescribed drugs. Polypharmacy can be problematic in elderly patients with cancer who are treated with chemotherapy.

In our institution, we wanted to combine a review of therapies with this geriatric evaluation in elderly patients with cancer or haematological diseases managed by a systemic oncological treatment. In this context, during the evaluation sessions in day hospital (HDJ) of oncogeriatrics on the Assistance Publique-Hopitaux de Marseille (AP-HM), a medical assessment and a cross analysis between the usual treatments of patients (herbal medicine) and self-medication) and chemotherapy and / or immunotherapy and / or targeted therapy and / or new generation hormone therapy are routinely performed. The main objective of this work is to evaluate the influence of the therapeutic revisions associated with the EGS data on the unplanned hospitalization rate at 3 months and then the secondary objective of the impact on the course of treatment oncology, to become patients and their survival. For this purpose, we want to conduct a pilot observational cohort study, monocentric, prospective, descriptive for patients convened in oncogeriatric HDJ and each patient is followed for 6 months.

Inclusion Criteria:

• Subjects over the age of 70 with an Oncoding score less than or equal to 14

The population of the study will be all patients over 70 years of age with oncogeriatric HDJ cancer prior to initiation of oncologic therapy such as chemotherapy (oral or intravenous) and / or targeted therapy and / or immunotherapy and / or hormone therapy. new generation.
