Abstract
BACKGROUND: Acromegaly patients, even those with IGF-1 values within the normal range receiving somatostatin receptor ligands (SRLs), often suffer from significant symptoms. It is not known to what extent patients' medical providers are aware of the frequency and severity of acromegaly symptoms or level of treatment satisfaction with SRLs. This study sought to examine the concordance between outcomes reported by acromegaly patients treated with long-acting SRLs and those perceived by their medical provider.Entities:

Fig. 1Acro-TSQ domain scores (N = 47). Due to “not sure” responses, sample sizes for medical provider-based domain scores are lower for Symptom Interference (N = 41) and Injection Site Interference (N = 7). Domain scores can range from 0 (most symptomatic/interference) to 100 (least symptomatic/interference)
