Impact of an APA Program on EFS in Patients With Diffuse Large-cell B Lymphoma Treated in 1st Line (PHARAOM)

Impact of an Adapted Physical Activity Program on Event-free Survival in Patients With Diffuse Large-cell B Lymphoma Treated in 1st Line

Diffuse large B cell lymphoma is the most common histology of non-Hodgkin's malignant lymphomas (31% of lymphomas), with an incidence of between 15 and 20 new cases per year per 100,000 inhabitants in France. The median age is 65 and a third of patients are over 75 years old. 60% of patients are cured after a standard regimen of chemotherapy with RCHOP; 40% of patients will, however, relapse. No other regimen has shown improvement in overall survival, but poor prognosis factors have been identified. Beyond these factors, other prognostic factors can impact overall and progression-free survival: sarcopenia, nutritional status disorders Sarcopenia is defined by the reduction of muscle mass and strength. It was first described in the elderly and classified as geriatric syndrome such as dementia, falls or frailty. It varies from 5 to 13% between 60 and 70 years and between 11 and 50% beyond 80 years and is classified as primitive, that is to say related to age It can however be secondary to neoplasia. This event has been described in patients with hematologic malignancies during chemotherapy and can reach 55% of patients in the elderly. It is proportional to the intensity of the treatments. It emerges as an independent prognostic factor which is detrimental to survival in these patients. Physical exercise combined with nutritional support could reduce it. The positive impact of adapted physical activity has been shown in numerous publications on reducing the incidence and risk of relapse for certain cancers (breast, colon prostate). It is less obvious in hematology in view of studies published on adapted physical activity . Adapted physical activity seems to provide a survival benefit in diffuse large cell B lymphoma however the number remains too low in this histology. Sarcopenia is an often-underestimated event and is associated with older age, co-morbidities, increased infectious complications, and early mortality. Correcting sarcopenia through appropriate physical activity could reduce its negative prognostic impact. The aim of the study is to increase the event-free survival of patients in the RCHOP and adapted physical activity arm by 15% compared to the standard arm.

During the first 3 cures, 3 APA sessions will be offered per week: 2 sessions of anaerobic type of 1 hour with muscle strengthening, stretching, flexibility and balance, supervised in the room, 1 aerobic type exercise session of 1.5 hours (Nordic walking: outdoors) or a 3rd indoor session if not possible, + home exercise book if the patient so wishes with record the time in minutes per session and the intensity felt and the modalities of the exercises carried out. During the 5 remaining cycles, 3 APA sessions will be offered per week: 1 session of 1 hour in an anaerobic exercise room (muscle strengthening, stretching, flexibility, balance) supervised, 1 session of anaerobic exercise per week in autonomy at home (with exercise book), 1 or more session per week of one hour of walking or cycling independently at home (aerobic effort) with declaration in the logbook of the intensity of exertion felt and the time in minutes per session.

APA sessions during chemotherapy with aerobic and anaerobic sessions on site and at home (+ home exercises book if the patient so wishes)

Event-free survival will be defined as the time between the date of inclusion and the date of the event or the date of the latest news if the patient is censored.

Evaluated according to the Foster method (duration of the session in minutes x perceived effort according to the modified Borg scale)

Time between the date of inclusion and the date of death if the patient is deceased or the date of the latest news if the patient is censored

time between the inclusion date and the date of the first examination showing Progression of the disease or the date of death if the patient is deceased or the date of the latest news if the patient is censored

Time between the date of the start of re-treatment and the date of the first examination showing progression of the disease or the date of death if the patient has died or the date of the latest news if the patient is censored,

Number of patients who presented complication in the numerator and the number of patients followed in the denominator

by CT scan during follow-up will be evaluated by the number of patients with sarcopenia diagnosed during follow-up in the numerator and the number of patients followed in the denominator

The number of patients with a disorder of nutritional status in the numerator and the number of patients followed in the denominator,

Number of patients with endocrinopathy between the inclusion date and the study discharge date in the numerator and the number of patients followed in the denominator
