| Abstract: | The results obtained with the various types of treatment in non-Hodgkin's lymphoma are reviewed and the data from the recent EORTC trials are summarized. In patients with Stage I follicular histology, regional radiotherapy (RT) alone gives excellent results. The long-term relapse-free survival (RFS) is high and relapsing patients can be rescued by aggressive combination chemotherapy; initial chemotherapy with CVP improves RFS but not total survival (TS). In patients with Stage I diffuse histology, the long-term survival is less satisfactory. CVP chemotherapy does not improve either RFS or TS; therefore if adjuvant chemotherapy is justified, it should be more aggressive than CVP. In patients with Stage II follicular type, regional radiotherapy alone gives good results. The addition of abdominal bath irradiation to regional RT increases RFS but not TS. After relapse, patients can be rescued by combination chemotherapy. In patients with Stage II diffuse histology, extended RT followed by CVP gives poor results and RT should be combined with more aggressive combination CT; the preliminary results of an integrated alternating regimen being excellent. In patients with Stage III and IV follicular type, the 8 year TS of patients treated with combination CT regimen (CHVP) followed by localized irradiation is approximately 55%, however the indications for the various types of treatment are still unclear. In patients with diffuse Stage III and IV, the results obtained with a combination CT regimen (CHVP) are still unsatisfactory, but are better in patients treated by a more aggressive CT regimen (CHVP-Bleo-VCR). Therefore aggressive CT associated with localized irradiation appears to be the best treatment. Further research should aim to identify the optimal combination CT regimen. In patients with high grade lymphomas who have relapsed the use of bone marrow autografts will be investigated. The present data show that besides histological type and age, the main prognostic factor is total tumor body burden as assessed by clinical stage, number of involved lymph node areas, and bulk of the disease. The study of the biological characteristics of the disease may provide more powerful prognostic indicators. |
