CIRCULATING STEM CELL AUTOGRAFTS IN HIGH‐RISK MYELOMA

BCG group and 12 in the control group. One died from REFERENCE another cause in each group. After a follow-up of more than 10 years, the difference in survival is no longer significant for all patients (P=O.I) (Fig 2a). Nevertheless the difference is significant if we consider only stages I and I1 (P=O.O13) (Fig 2b) or high grade malignancy (Kiel’s and W.F. classification) Hcerni. B., Durand. M.. Richaud.

Further follow-up has strengthened our initial findings, supporting the use of adjuvant immunotherapy with BCG in some subsets of non-Hodgkin’s malignant lymphomas. This conclusion is supported by the benefit of BCG therapy for disease-free survival of all patients of our trial: and for actuarial survival and disease-free survival for stages I and I1 or high grade malignancy.
