|Abstract:||Patients with indolent non-Hodgkin lymphoma (iNHL) undergo regular active surveillance in between treatment periods to detect disease relapse or progression. As part of surveillance, international guidelines recommend regular routine blood testing, which is based on consensus rather than evidence of utility. We conducted a retrospective analysis of all patients older than age 16 years diagnosed with grade 1-3A follicular or marginal zone lymphoma between 2008 and 2017 from 2 Australian cancer centers to assess the utility of full blood examination, lactate dehydrogenase, and β2-microglobulin in detecting progression events, defined as either disease relapse or progression of disease. One hundred eighty patients attended 1,757 outpatient appointments (median follow-up, 36 months). Routine blood tests (RBTs) were performed before 83% of appointments. Seventy-four progression events occurred in 62 patients. Only 2 events (3%) were detected by RBTs alone, both of which occurred in treatment-naïve patients who subsequently developed symptoms within 3 weeks. The remainder of progression events were suspected clinically (88%) or detected by imaging (9%). RBT results were frequently abnormal in asymptomatic patients (19%), with abnormal results leading to either additional investigations or an increased surveillance frequency in 8% of cases. The overall sensitivity and positive predictive value of abnormal RBT results in detecting progression events were 39% and 9%, respectively. RBTs have poor performance characteristics and rarely detect clinically significant disease progression or relapse in asymptomatic patients with iNHL.|
