Background:
The aim of this study was to determine in a randomised trial whether there is any significant difference in toxicity between modified CHOP and MCOP chemotherapy in elderly patients with aggressive non-Hodgkin’s lymphoma (NHL) and to determine whether this reduced dose chemotherapy can be administered with full dose intensity, low toxicity and produce acceptable survival.
Patients and methods:
Between 1993 and 2000, 155 eligible patients were randomised into this trial mainly from three centres (Nottingham, Birmingham and Leeds, UK). The patients were newly diagnosed with aggressive NHL and had a median age of 74 years (range 65–91 years). Ninety-six patients (62%) had bulky stage I or II disease; 59 patients (38%) had either stage III or IV disease; 77% had one or more extranodal sites involved at presentation; and 31% showed B symptoms. Seventy-seven patients were randomised to receive six cycles of modified CHOP (cyclophosphamide 600 mg/m2 i.v., doxorubicin 30 mg/m2 i.v., vincristine 1 mg i.v. all on day 1 with prednisolone 20 mg bd for days 1–5) every 21 days and 78 patients to MCOP (mitozantrone 10 mg/m2 i.v. substituted for doxorubicin). Growth factors were not used routinely. After completion of chemotherapy, 39 patients received involved field radiotherapy (35–40 Gy) in 20 fractions.
Results:
One hundred and one patients (65%) completed all six cycles of chemotherapy. The median course dose intensity was 97%. The median follow-up for 53 surviving patients was 51 months. The median survival was 19 months (95% confidence interval 10–36 months) with an actuarial survival of 47% at 2 years and 42% at 3 years (CHOP versus MCOP, P = 0.79). There was no significant difference in any of the toxicities experienced with either CHOP or MCOP, except for white cell count (46 patients on MCOP and 27 patients on CHOP had grade 3 or 4 toxicity, P = 0.002) and red cell transfusion (37 patients, MCOP; 17 patients, CHOP; P = 0.001). Grade 3 or 4 neutropenia was documented in 75 patients (50%). One patient died from toxicity whilst in remission and seven patients died with septicaemia and persistent NHL.
Conclusion:
This multicentre randomised trial provides further information on the dose intensity achievable with CHOP or MCOP regimens in elderly patients (median age 74 years) with aggressive NHL. These dose-reduced regimens can be given with nearly 100% dose intensity with 65% of patients completing all the treatment. Survival is comparable to that observed with the more intensive regimens given in this age group.
