Background: Non-Hodgkin Lymphomas (NHL) represent a recent and fascinating domain of hemato-oncology, in which remarkable progress has been made. The conventional treatments of indolent lymphomas do not extend the survival rate, nor do they cure. Recent directions are centered on using several new drugs that are capable of overcoming the mechanisms that are resistant to recovery. The initiation of immunotherapy (Rituximab in 1997) seems to have changed the natural evolution of follicular lymphomas (FL). It is possible that resistance to healing in follicular lymphomas may be neutralized with Rituximab by suppressing STAT-1 positive macrophages that are present in the cellular microenvironment.Thereinafter, the re-evaluation of recent models of prognostic and therapeutic paradigmas that were used in FL became compulsory.The purpose of the paper is to compare the evolution of patients with follicular lymphoma and the period of response, according to the treatments.
Material and method: The study group consisted of the 71 patients diagnosed with follicular lymphoma, out of a total of 767 malignant lymphatic proliferations with B cells, for a period of 7 years (2002-2008), at the Hematology Department, Hospital Coltea, Bucharest and Hematology Department, Universitary Hospital, BucharestResults and conclusions: Combining chemotherapy with Rituximab had better results compared to the same chemotherapy, administered alone, both in induction and in case of relapse. The overall response rate in our study group was 74.7%, out of which 42.3% complete remissions. The overall response rate was 84.61% in the Rituximab group, compared to 68.88% in patients without Rituximab.
