A role of interim positron emission tomography/computed tomography scan in the management of Hodgkin lymphoma: A single-center study in a developing country

Abstract

BACKGROUND: The Hodgkin lymphoma (HL) showed a good prognosis in Erbil city. However, a number of deaths were reported. The monitoring and treatment strategies of HL had improved in the last decade. AIMS: The aims of this study were to evaluate the prognostic value of interim positron emission tomography/computed tomography (PET/CT) scan in HL patients and predicting the survival outcome in addition to effect on progression-free survival (PFS) of HL patients. PATIENTS AND METHODS: A retrospective cross-sectional study was conducted in Nanakali Hospital in Erbil city, Kurdistan region, Iraq, through reviewing data of patients with HL from January 1, 2014, to December 31, 2019, on a sample of 75 HL patients. The diagnosis of HL was accomplished by the physician regarding lymph node biopsy by the World Health Organization criteria. The PET/CT scan was done after two treatment cycles. PET/CT of HL patients was done in a private center in Erbil city (Media Diagnostic Center). RESULTS: The mean overall survival duration of HL patients was 5.39 years with an overall survival rate of 92%, and the mean PFS duration of HL patients was 5.04 years with PFS rate of 76%. The mean overall survival of HL patients with positive interim PET/CT (4 years and rate 75%) was lower than the mean overall survival of HL patients with negative interim PET/CT (7.2 years and rate of 95.2%) with a significant difference (P < 0.001). CONCLUSIONS: The interim PET/CT scan is useful in prognosis of patients with HL and predicting overall survival and mortality.
