PET/CT IN ASSESSING THE LYMPHOMA RESPONSE
 TO TREATMENT

Abstract

Relevance: PET/CT has become an integral part of the diagnostic algorithm in lymphoma patients since lymphomas actively accumulate 18F-FDG. The high accuracy of PET/CT in patients with certain lymphoma types allows effective use of this method in clinical practice
 for diagnosis, staging, re-staging, evaluating the effectiveness of treatment, and determining further patient management tactics.
 The study aimed to evaluate the PET/CT capacity in assessing lymphoma treatment effectiveness.
 Methods: We conducted a retrospective analysis of PET/CT 18F-FDG results in 109 patients with a verified lymphoma diagnosis. The
 patients underwent PET/CT examinations at “Orhun Medical” PET/CT center based in the JSC “Kazakh Institute of Oncology and Radiology” (Almaty, Kazakhstan).
 Results: According to PET/CT results in assessing the lymphoma treatment effectiveness, the stabilization of the process was achieved
 in 38.5% of cases, progression – in 33.03%, a partial metabolic response – in 18.35%, and a complete response – in 10.09% of cases.
 Conclusion: PET/CT is the method of choice for evaluating the effectiveness of lymphoma treatment compared to other radiological
 techniques. PET/CT is based on determining metabolic treatment response, not only on size indicators. It plays an essential role in different
 stages of lymphoma treatment, providing new opportunities for personalized treatment
