Abstract
Background. Bone marrow is the mostfrequent metastatic site in follicular lymphoma, 40-70 % cases. It’s unfovourable prognostic role is stated in the index FLIPI-2 (Follicular Lymphoma International Prognostic Index-2). Objective. To study both prognostic role of bone marrow involvement and it’s relation to erythropoiesis peculiarities in follicular lymphoma was the purpose of this research. Materials and methods. Histological study was performed in 269 follicular lymphoma patients. Erythropoiesis peculiarities were studied in that patients according to standard myelogram analysis. Results. Bone marrow involvement was noted according to trephine biopsy section staining in 37,9 % of follicular lymphoma case (102 from 269). Bone marrow involvement did not influenced the prognosis (overall survival) in all period of observation (p = 0,18). Longterm survival (more than 48 months) was negatively influenced by bone marrow involvement (p = 0,04). Intertrabecular pattern of follicular lymphoma growth in bone marrow was negative prognostic factor (p = 0,02). We noted negative correlation between bone marrow involvement and the elevation of orthochromic normoblasts in bone marrow of patients with follicular lymphoma. In cause of bone marrow such elevation was noted in 67 %, and in the absense of involvement - in 78 % (p = 0,043). Elevation of orthochromic normoblasts did not influenced the overall survival of follicular lymphoma patients (p = 0,89). Conclusion. Bone marrow involvement in follicular lymphoma plays prognostically unfavourable role in long-time observation periods (later than 48 months). The most unfavourable are the intertrabecular patchy lesions. Involvement of bone marrow is in opposite relations to elevation of orthochromic normoblast, but the latter sign is of no prognostic significance.
