Abstract

BACKGROUND. The goal of the current study was to evaluate the impact of presentation with an age-adjusted International Prognostic Index (aaIPI) score of 2 or 3 on patients with high-risk aggressive lymphoma who are treated with frontline intensive chemotherapy and autografting. METHODS. Sixty-nine consecutive patients (median age, 40 years) with either B-cell (n = 60) or non-B-cell (n = 9) aggressive lymphoma were treated with high-dose sequential (HDS) chemotherapy and peripheral blood progenitor cell (PBPC) autografting. The patients who were examined had poor prognoses, with aaIPI scores of 2 (n = 37) or 3 (n = 32). The original treatment regimen, sequential delivery of cyclophosphamide, methotrexate, and etoposide, followed by PBPC autografting (o-HDS), was used in the first 32 patients; the program was intensified by the addition of a course of high-dose cytosine arabinoside (C-HDS) in the next 37 patients. RESULTS. There were 4 toxicity-related deaths - 2 in each aaIPI subgroup (treatment-related mortality, 5.8%). The complete remission rate was significantly higher among patients with an aaIPI score of 2 (n = 32 [86%]) compared with those with an aaIPI score of 3 (n = 13 [41%]; P <0,001), Patients with an aaIPI score of 2 had significantly better outcomes than did patients with an aaIPI score of 3 in terms of both overall survival (78% vs, 34% at 8 years; P <0.001) and event-free survival (72% vs. 28% at 8 years; P <0.001). Similar results were observed when the analysis was limited to the 60 patients with B-cell-derived lymphoma. No significant differences in outcome between patients receiving o-HDS and patients receiving C-HDS were observed. Multivariate analysis demonstrated that an aaIPI score of 3 was the only parameter that was significantly associated with poor overall and event-free survival. CONCLUSIONS. Age-adjusted International Prognostic Index score is applicable to patients with aggressive lymphoma who are treated with frontline intensive chemotherapy and autografting. In addition, upfront use of HDS chemotherapy appears to be beneficial to patients with an aaIPI score of 2 but not to those with an aaIPI score of 3.
