Clinicopathology Figures and Survival of Non-Hodgkin’s Lymphoma in Iran

Background: Non-Hodgkin’s lymphoma (NHL) is the fifth most frequently diagnosed cancer whose incidence has risen by at least 100 percent over the past five decades especially in the West. Objectives: The aim of this study is to investigate Clinicopathology figures, overall survival (OS) and Progression-free survival (PFS) in patients with NHL in Iran. Methods: In a descriptive study, 143 patients referred to Clinic of Hematology in two centers between 2005 and 2014. We checked age, sex, types and subtypes of NHL; recurrence, Ki-67, organomegaly, lymphadenopathy, radiotherapy, OS and PFS in the patients. The mean follow-up was 49 months. All patients received R-CHOP regimen for 6 to 8 cycles. Results: The mean age at diagnosis for the patients was 46 years (range, 16 - 82) and 76.9% had age < 60 years and 62.2% were male. 58% patients had primary nodal NHL and out of 139 patients, 88.5% were aggressive NHL. Organomegaly and lymphadenopathy were in 12 patients (8.4%) and 80 (55.9%), respectively. Of all patients, 106 patients (74.1%) were treated with radiotherapy. 2-year OS rate was 91.5% and 5-year OS rate was 85%.2-and 5-year PFS rates were 79.6% and 63.3%, respectively. Conclusions: Percentage of NHL in males is more than females and the median age is around 45 years. Also, the prevalence of nodal is more compared with extranodal in NHL patients.
