Stratification of Patients in Oncogeriatrics and Personalization of Interventions

Stratification of Patients in Oncogeriatrics and Personalization of Interventions

Multicenter randomized controlled trial. Patients will be randomly assigned to the control group or the intervention group in each of the health centers.

The control group will receive the usual care, while the intervention group will add an individualized physical exercise program to the usual care.

Cancer is a disease of the elderly. More than 65% of all malignancies affect this population. At the same time, the incidence of cancer cases increases and the need to better understand the biological characteristics of the disease, as well as those of the elderly who suffer from it, is highlighted.

Oncogeriatrics is the area that addresses the care of the elderly patient with cancer, taking into account that physiological aging causes older people to have their own characteristics that require a differential approach in care. The low inclusion in clinical trials of elderly patients and the few specific trials carried out in this subpopulation together with the progressive aging of the population mean that the development of this area has become a priority in health policies.

Therefore, there is a need to focus the research area on supervised physical exercise in older people with cancer in an innovative way, with the aim of generating new hypotheses that overcome existing limitations and facilitate the introduction into the health system of this type of interventions.

It seems useful to have instruments that help to objectively evaluate the fragilty and comorbidity of patients with the intention of adequately indicating the administration of antineoplastic treatment. In addition, nowadays, with the arrival of new less toxic treatments, it is essential to make a good selection of the patients to be treated, since there is a risk of treating patients who are not going to benefit from an active treatment just for having more comfortable medications and with less toxicity.

There are several instruments that can help to better select the patients that the investigators are going to treat and to select the supportive care that can help to better tolerate the proposed treatments while maintaining the best possible quality of life. Some of those instruments are aimed at detecting fragility such as comprehensive geriatric assessment. They identify in more detail the different vulnerabilities that can affect the patient in the benefit vs. toxicity balance of the treatment and in the long-term quality of life

Many authors emphasize the importance of including a physical exercise program during and after cancer treatment. Despite this, older people with cancer usually have low levels of physical activity, and few adhere to the recommendations they receive from health centers. For this reason, involving older people with cancer in a regular physical activity program becomes a challenge for those in charge of health centers.

Some studies have shown that physical exercise can reduce the usual loss of functional capacity and reduce frailty during cancer treatment. On the other hand, physical exercise can help reduce pain, toxicity and improve the completion rate of systemic treatment. Recent studies have found that physical exercise on the days of chemotherapy cycles is safe and may be beneficial in reducing neuropathy and maintaining physical well-being. Additionally, physical exercise can impact one of the most common and strenuous adverse effects of cancer treatment, fatigue.

Inclusion Criteria:
