Analysis of Clinical Characteivstics and Therapeutic Efticacy of 54 Patients with Mantle Cell Lymphoma / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyse the clinical characteristics and therapeutic efticacy of patients with mantle cell lymphoma(MCL).</p><p><b>METHODS</b>The clinical data including cliniced parameters and laboratorial test results of 54 patients with MCL were collected and restrospectively analyzed to clarity the clinical characteristics of MCL and to evaluate the survival and factors affecting prgnosis of patients.</p><p><b>RESULTS</b>The incidence of MCL accounted for 4.0% of NHL in our center. The median age of MCL patients was 63 years old, the male and female ratio was 1.4∶1. The MCL patients inⅢ-Ⅳ stage accounted for 96.3%; the extranodal organ involvement existed in 98.1% patients, the most common extranodal involvement sites were bone marrow(72.2%), spleen(51.9%), gastrointestinal tract(25.9%). The overall response rate(ORR) was 66.7%, among which the complete remisson (CR) rate was 37.1%, 3 year and 5 year-progression free survival rate was 52.7% and 34.7% respectively, 3 year and 5 year overall survival rate was 60.4% and 49.6% respectively. The therapeutic efficacy in chemotherapy combined with cytarabine group was suprior to that in chemotherapy group without cyteratine, the chemotherapy comtined with auto-HSCT could further improve the prognosis of patients. The unvariatc analysis showed that the KI67 level, B sgmptom, liver function, LDH and C-RP levels, initial therapeutic efficacy, high dose cytarabine regimen, auto-HSCT and relapse-refractroy status were prognosis-related factors; the multi-variate analysis showed that the initial therapeutic efficacy and relapse rcfractory stasus were independent prognostic risk factors. Analysis showed that the surival of patients stratified according to MIPI and MIPI-c indexes was significantly different from that stratified by IPI index.</p><p><b>CONCLUSION</b>The MCL patients commonly complicated by extranodal involvement and have poor prognoss. Using the chenotherapy regimen combined with high doge of cytarabine as induction therapy and auto-HSCT as consotidatory therapy shows the significont efficacy for survival of young patients with MCL. The MIPI and MIPIc indexe are more much suitable for prognosis evaluation of MCL patients.The initial therapeuntic efficacy and relapse-refractrong status are the independant prognosis-related factors.</p>
