A retrospective analysis was performed of 117 non-Hodgkin's lymphoma (NHL) patients (72 male and 45 female, mean age 55 years) treated at NCKUH between July 1988 and December 1993. Of the 115 patients who could be classified by Ann Arbor staging system, 26 patients (22.2%) were in stage 1; 23 (19.7%) in stage 2; 29 (24.8%) in stage 3; and 37 (31.6%) in stage 4. According to the International Working Formulation, three patients (2.6%) were low grade NHL, 90 (76.9%) were intermediate, and 8 (6.8%) were high grade NHL. Histologically, diffuse large cell NHL accounted for 52.1% of cases, followed by 16.2% of cases exhibiting diffuse mixed NHL. Immunophenotype analysis was available in 95 cases, which revealed 76 (80%) cases exhibiting B-cell origin, 17 (18%) cases exhibiting diffuse mixed NHL. Immunophenotype analysis was available in 95 cases, which revealed 76 (80%) cases exhibiting, B-cell-origin, 17 (18%) cases exhibiting T-cell origin and 2 (2%) cases were of null cell type. All patients underwent two groups of induction chemotherapy, either CHOP (Cyclophosphamide, Epirubicin, Oncovin, and Prednisolone) or 'modified' COPBLAM (Cyclophosphamide, Epirubicin, Oncovin, Vinblastine, Bleomycin, Procarbazine, and Prednisolone). Seventy-two cases treated through COPBLAM and 45 cases treated through CHOP were evaluated. The response rate (RR) to COPBLAM treatment was 72.2% and was 68.9% for the CHOP group (P = 0.51). The 5-year overall survival rate (OAS) was 44.1% for COPBLAM, versus 40% for CHOP (P = 0.15). The disease-free survival (DFS) was 72.6% at 63 months for COPBLAM and 58% at 51 months for CHOP (P = 0.16). Neither B cell nor T-cell lineages of NHL showed any statistical difference in RR (P = 0.53), DFS (P = 0.58) or OAS (P = 0.97) to the different treatments. Using multiple logistic analysis, two independent factors, high LDH and advanced stage, were found to adversely affect the rate of complete remission. The application of the International Prognostic Index to our patients needs modification, which suggests the necessity of more evaluation before it can accurately be applied to all international series of NHL.
