Abstract:
Objective To study clinical manifestations, diagnosis, treatment, as well as effect of surgical operation, of primary mediastinal large B-cell lymphoma (PMBCL).Methods Data of 19 patients of PMBCL with complete clinical and pathological records hospitalized at Peking Union Medical College Hospital during 1998 to 2008 were retrospectively reviewed and analyzed.Kaplan-Meier method was used to estimate their survival time and survival rate in comparison of efficacy in those with surgical operation to those without it.Results Overall three-year survival rate was 54% for all the 19 patients, 55% for those with surgical operation and 54% without it, respectively, with an average survival time of 44 months, 44 months for those with surgical operation and 42 months without it, respectively, but not reaching at statistical significance.Symptoms of superior vena cava syndrome in five cases at admission relieved immediately after surgical operation, but symptoms of superior vena cava syndrome in three of nine cases in non-surgical group relieved gradually one to three weeks after chemotherapy.Conclusions Surgical operation has no significant effect on survival in patients with PMBCL, but it can relieve syndrome of superior vena cava syndrome and provide accurate pathological diagnosis.
