Modulated Chemotherapy According to Modified Comprehensive Geriatric Assessment in 100 Consecutive Elderly Patients with Diffuse Large B‐Cell Lymphoma

Learning Objectives: After completing this course, the reader will be able to: Use a modulation of chemotherapy according to modified geriatric assessment to improve outcomes for elderly patients with diffuse large B‐cell lymphoma with an acceptable level of toxicity. Offer elderly patients the best tailored treatment while minimizing the dose‐limiting toxicity. This article is available for continuing medical education credit at CME.TheOncologist.com Chemotherapy is associated with toxicity in elderly patients with potentially curable malignancies, posing the dilemma of whether to intensify therapy, thereby improving the cure rate, or deescalate therapy, thereby reducing toxicity, with consequent risks for under‐ or overtreatment. Adequate tools to define doses and combinations have not been identified for lymphoma patients. We conducted a prospective trial aimed to evaluate the feasibility and efficacy of chemotherapy modulated according to a modified comprehensive geriatric assessment (CGA) in elderly (aged ≥70 years) patients with diffuse large B‐cell lymphoma (DLBCL). In June 2000 to March 2006, 100 patients were stratified using a CGA into three groups (fit, unfit, and frail), and they received a rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone modulated in dose and drugs according to comorbidities and activities of daily living (ADL) and instrumental ADL scores. Treatment was associated with a complete response rate of 81% and mild toxicity: grade 4 neutropenia in 14%, anemia in 1%, and neurological and cardiac toxicity in 2% of patients. At a median follow‐up of 64 months, 51 patients were alive, with 5‐year disease‐free, overall, and cause‐specific survival rates of 80%, 60%, and 74%, respectively. Chemoimmunotherapy adjustments based on a CGA are associated with manageable toxicity and excellent outcomes in elderly patients with DLBCL. Wide use of this CGA‐driven treatment may result in better cure rates, especially in fit and unfit patients. A prospective trial aimed at evaluating the feasibility and efficacy of chemotherapy modulated according to a modified comprehensive geriatric assessment in elderly (aged ≥70 years) patients with diffuse large B‐cell lymphoma was conducted. Chemotherapy adjustments based on a comprehensive geriatric assessment were associated with manageable toxicity and excellent outcomes.
