Abstract:
Objective To investigate the clinical characteristics, treatment outcomes and prognostic factors of patients with malignant lymphoma with primary retroperitoneal mas as the primary presentation.
Methods A total 20 cases of malignant lymphoma with primary retroperitoneal presentation lymphoma seen in our hospital from January 2002 to Decemter 2010 Biopsy method, tissue pathology, immunochemistry, treatmemt outcome and long time survival were analyzed retrospectively. The influences of age, sex, pathologic type, clinical stage, huge mass and B symptom were analyzed.
Results Among the 20 cases, 11 (55 %) were diffuse large B cell lymphoma, 4 (20 %) were follicular lymphoma, 2 (10 %) were B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma, 1 (5%) was lymphoblastic lymphoma, 1 (5 %) was anaplastic large cell lymphoma and 1 (5 %) was Hodgkin lymphoma. Among the 20 cases, 7 (35 %) had complete remission, 8 (40 %) had partial remission, 5 (25 %) died. The 3-year accumulated survival of the whole group was 30 %, The 5-year accumulated survival of the whole group was only 20%.
Conclusion Complete remission rate and long term survival rates of malignant lymphoma with primary retroperitoneal presentation were low. Pathological type, surgery, huge mass, B symptom, hepatic deysfunction, and infiltrating surrounding organs significantly affect long term survival.
