Patient And Nurse Experience Of Using Somatostatin Analogues To Treat Gastroenteropancreatic Neuroendocrine Tumors: Results Of The Somatostatin Treatment Experience Trial (STREET)

Evaluate patients' and nurses' experiences, including injection problem frequency, with the somatostatin analogues (SSAs) lanreotide autogel (Somatuline autogel , deep subcutaneous) and octreotide long-acting release (LAR) (Sandostatin LAR , intramuscular) when treating gastroenteropancreatic neuroendocrine tumors (GEP-NETs). An observational, cross-sectional study across 2 NET centers in Sweden. Questionnaires based on participants' most recent injection experience were sent to patients with GEP-NETs treated with octreotide or lanreotide, and to nurses administering these treatments. Nurses were identified via patients completing their questionnaires. Resource use was sourced from Swedish prescription registry records. The planned sample size was 200, based on an estimated proportion of 0.50 and ±7% precision. 119/156 patients (n=53, lanreotide; n=66, octreotide) and 43/53 nurses (n=22, lanreotide; n=21, octreotide) completed questionnaires. Despite smaller recruitment than planned, the endpoint precision was ±9% with 119 participants, and still considered reasonable. More octreotide-treated patients reported problems (18% vs none; =0.001) and experienced moderate-to-high anxiety pre-injection (11% vs 2%). Patients had similar physical HRQoL scores overall (Short Form-12 mean composite scores: physical: 39.4 vs 37.6; mental: 50.7 vs 49.6). The mean number of lanreotide and octreotide doses dispensed per year were 11.1 and 12.6, respectively (
