The relationship between immunophenotype, histopathology and clinical stage in influencing prognosis was evaluated in 99 cases of non-Hodgkin's lymphoma (NHL). All cases were histopathologically classified according to the system of the international conference on working formulation (WF), immunologically analysed by flow cytometry with a panel of monoclonal antibodies and clinically staged by the Ann Arbor scheme. Eighty eight percent of T- and 87.7% of B-phenotype NHLs respectively received combination chemotherapies with or without radiotherapy. Early stages I and II showed higher response rates (86% for T- and B-NHL) compared to the advanced ones III and IV (58% for T-NHL and 65% for the B-NHLs), p<0.05. Higher overall survival rates were observed in low and intermediate grade NHLs, p < 0.05. The early stages further showed relatively higher survival rates in T- than in B-phenotype of intermediate grade NHL. Low grade NHL had the highest survival rates in both early and advanced stages, whereas the survival rate was the lowest in high grade NHL irrespective of the clinical stages. Immunophenotype, pathological grade and clinical stage jointly displayed varied predictive values in the prognosis of NHL. Since the present prognostic models are based on histological and staging criteria only, the results suggest that, phenotype should be included in the classification systems or prognostic models for the NHLs, thus facilitating the establishment of effective lineage specific therapies.
