114Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. Annual incidence increases with age and achieves more than 30 per 100 000 patients 65 years old or over.
Despite high response rates with conventional regimen as R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristine and Prednisone), 30% to 40% of patients develop a relapse or a refractory disease, with a poor prognosis. There is no standard chemotherapy in second line for elderly patients, which are not eligible to receive a salvage treatment by high-dose therapy followed by autologous stem cell transplantation. The median progression-free-survival (PFS) is less than one year with the most commonly used regimens including R-Gemcitabine-Oxaliplatin (R-GEMOX) and R-Bendamustine. One the other side, Rituximab plus Lenalidomide, an immunomodulatory agent, is an active new therapeutic approach, with an efficacy proved in a phase II trial with a patients with a prolonged disease-free-survival of 32 months for responders in patients with a median age of 74 years old. This combination is also efficient in the ABC phenotype DLBCL which is more common in elderly patients.
For elderly patients, a management of the geriatric impairment together with lymphoma is required. Indeed, a comprehensive geriatric assessment detects frailty and vulnerability in elderly with a lymphoma and predicts severe treatment related toxicity, treatment settings and progression free survival. Moreover, geriatric intervention improved outcome, autonomy and quality of life. Functional status, assessed by Activities of patients Daily Living (ADL) is an independent predictive factor for feasibility of chemotherapy in elderly patients with cancer. The mini Data Set of DIALOG group is a new simplified geriatric assessment for oncologist.
patients ≥ 75 years old with relapsed Diffuse large B-cell lymphoma will be treated with classical Rituximab-based chemotherapy or Rituximab plus Lenalidomide.
patients ≥ 75 years old with relapsed Diffuse large B-cell lymphoma will be treated with Rituximab plus Lenalidomide. Four 28-days cycles of oral Lenalidomide (20 mg / d for 21 days) and Rituximab 375mg/m2 on day 1 and day 21. After this induction phase, patients achieving at least stable disease were given lenalidomide maintenance therapy (20 mg for 21 days) until progression
A comprehensive geriatric assessment (CGA) is recommended by the Société Internationale d'Onco Gériatrie (SIOG) in order to assess all geriatric facets (comorbidity, functional impairment, nutritional status, mental and psychological status, environment,…) on which treatment may impact.
Activities of daily living (ADL) comprise the basic actions that involve caring for one's self and body, including personal care, mobility, and eating. The Index ranks adequacy of performance in the six functions of bathing, dressing, toileting, transferring, continence, and feeding. Clients are scored yes/no for independence in each of the six functions. A score of 6 indicates full function, 4 indicates moderate impairment, and 2 or less indicates severe functional impairment.
Rituximab-based physician's choice chemotherapy
Four 28-days cycles of oral Lenalidomide (20 mg / d for 21 days) and Rituximab 375mg/m2 on day 1 and day 21. After this induction phase, patients achieving at least stable disease were given lenalidomide maintenance therapy (20 mg for 21 days) until progression.
