OBJECTIVE: To predict the prognostic factors and to improve the response and survival in intermediate-grade and high-grade non-Hodgkin lymphoma (NHL).
METHODS: 200 patients with intermediate-grade and high-grade NHL were treated with chemotherapy. A multivariate Cox model was used to analyse the prognostic factors that significantly affect the treatment outcome. The variables examined included: sex, age, clinic stage of disease, B symptoms, extranodal sites, bone marrow involvement, tumor bulk, performance status (ECOG) and malignancy grades.
RESULTS: Multivariate analysis showed that performance status, the number of extranodal sites, pathologic malignancy grade and tumor bulk were significantly independent prognostic factors. These factors were put together to construct a prognostic index formula. The index partitioned the patients into low risk group (PI -2.43(-)-1.30), intermediate risk group (PI -1.29-1.0) and high risk group (PI > 1.0) giving 5-year survival rates of 76.0%, 21.6% and 7.4%, respectively.
CONCLUSION: The prognostic index formula and subgroups could serve as a reference to distinguish patients requiring more intensive chemotherapy and autologous stem cell transplantation from those who should be treated with standard regimens in order to improve the prognosis.
