Title

Cytogenetic and molecular follow-up study on 259 bone marrow transplanted patients in Iran

English Abstract

Introduction: Bone marrow transplantation (BMT)is the treatment of choice for many patients with poor prognosis, relapsed or refractory leukemia who have matched donors, and one the attractive points in hematopoietic studies is to investigate chimerism. Patients and Methods: Investigation was carried out in 259 patients at diagnosis. The most frequent disease included thalassemia (88), AML (53), CML (30), ALL (16) and others (72). The cytogenetic study was carried out on BM-cells and/or PB-lymphocytes according to the standard culture procedures and GTG. In some cases, FISH and molecular investigation on 4 exons of P53 gene, by PCR-SSCP and heteroduplex analysis techniques were carried out. Results and Conclusion: Cytogenetic investigation was focused on 190 patients at diagnosis (Pre-BMT) and 120 patients at post-BMT. Among donors, 97.9% were first-degree relatives (58.3% brother and 39.6% sister). In CML-patients 93.4% were philadelphia-positive. The most frequent chromosome alterations were: (1) In thalassemia-patients, in pre-BMT small 1qh(20%) and 9qh+ (20%), as polymorphisms and del (1)(q13), del (4)(13) and del (10) and in post-BMT: gains of X (14.6%), Y (10.6%), ... . the preliminary data on mutation detection of 4 exons in P53 gene revealed 10% shifts by application of the dual techniques including PCR-SSCP and heteroduplex analysis. The present data could lead us to plan a multidisciplinary investigation, including cytogenetic and molecular genetics for the BMT-patients.
