Lymphoma in older patients.
One half of patients newly diagnosed with lymphoma are older than 60 years and a significant proportion of them older than 80 years. Older patients treated for lymphoma may not tolerate the high-dose therapies used in younger patients, usually because of the presence of concomitant diseases. Diffuse large B-cell lymphoma represents more than 60% of all lymphomas seen in older patients. Clinical presentation and prognostic parameters are identical to those described in young patients. However, response rate is usually lower in elderly patients compared with young patients, even if the patients are treated with the cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen. Therefore, event-free and overall survival rates are shorter in elderly patients, even if disease-free survival rates are not really shorter than in young patients. Rituximab added to the CHOP regimen has recently been shown to dramatically improve the survival of these older patients without increasing the toxicity of the treatment. Patients older than 80 years may also be treated with rituximab plus CHOP, except for those having severe organ failure secondary to other diseases. Very few of these older patients may benefit from a salvage treatment after relapse.
