Nodular malignant lymphomas: factors affecting complete response rate and survival

Abstract

The records of 109 patients with non-Hodgkin's lymphoma of nodular pattern were reviewed to determine which factors were associated with a favorable response to therapy and prolonged survival. A logistic regression model was utilized to identify the pertinent variables. Prognostic factors associated with a favorable response were, in order of decreasing importance: treatment with an Adriamycin combination regimen, absence of bulky tumor, and no exposure to prior chemotherapy. Thos associated with prolonged survival were: normal hemoglobin level, treatment with an Adriamycin combination regimen, female sex, and no prior exposure to therapy. Achievement of complete remission in these disorders resulted in a statistically longer duration of survival compared to partial responses or failures. Patients whose complete remission was induced with an Adriamycin-containing regimen and maintained with BCG immunotherapy had a significantly longer complete remission than those who did not receive BCG. Knowledge of these factors can be important in planning and analyzing future therapeutic trials.
