The study evaluates the effectiveness of true whole-body (TWB) PET/CT imaging compared to limited whole-body (LWB) imaging for assessing extranodal NK/T cell lymphoma (ENKT) staging and treatment strategies.
Out of 225 patients diagnosed with ENKT, a significant majority (88.9%) had tumors confined to the LWB range, with only 11.1% showing unexpected lesions in the distal extremities.
The findings suggest that TWB PET/CT is not recommended for initial diagnosis but may be utilized for follow-up in patients, particularly where progressive disease is suspected.
