    Abstract:
    Due to concerns about toxicity, many elderly patients with aggressive non-Hodgkin's lymphoma (NHL) are not considered candidates for standard chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP). The cytoprotective agent amifostine has the potential to reduce toxicity when added to chemotherapy. The purpose of the current study was to examine the toxicity of CHOP combined with amifostine in elderly patients with aggressive NHL. A prospective phase II study was performed in patients aged 60 years and older. Patients with stage I/II disease received 4 cycles of CHOP followed by involved-field irradiation. Patients with stage III/IV received 6-8 cycles of CHOP. Amifostine (740 mg/m(2)) was administered as a 15-min i.v. infusion immediately before chemotherapy. Forty-one (median age 69.5 years, range 60-87) of 49 consecutive previously untreated patients, aged 60 years and older, with aggressive NHL seen in our center were included in the study. Twenty-one patients had stage I/II disease and 20 had stage III/IV disease. The patients received a total of 207 cycles of amifostine-CHOP. Infusion of amifostine caused mild to moderate transient side effects, including a drop of systolic blood pressure >20 mmHg in 54 cycles and nausea/vomiting in 36 cycles. Hematotoxicity of CHOP consisted of leukopenia grade 4 in only 15.4% of cycles. There were two cases of grade 3 anemia. No thrombocytopenia higher than grade 2 occurred. Febrile neutropenia was rare, occurring in 4.3% of cycles. One patient died after the first CHOP administration because of anthracycline-related acute cardiomyopathy (corresponding to a toxic death rate of 2.4%). The complete response rates were 85 and 75% in stage I/II and stage III/IV patients, respectively. After median follow-up of 33 months (range 17-50 months) the median overall survival was not reached in patients with stage I/II and was found to be 32 months in patients with stage III/IV. At 2 years, 76% of patients with stage I/II and 70% with stage III/IV were alive. Twelve of the 15 patients who died were aged older than 70. Amifostine pre-treatment was associated with a low toxicity of CHOP in elderly patients with aggressive NHL treated with curative intent. Treatment outcomes appeared not to be impaired by the addition of amifostine to CHOP. This schedule merits further testing in a randomized trial.
