摘要

Background and Objectives

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a rare diverse group of malignancies, which range from well-differentiated indolent tumors to high-grade aggressive forms. Based on the World Health Organization classification, GEP-NETs are divided into well-differentiated neuroendocrine tumors and poorly differentiated carcinomas. While localized GEP-NETs are primarily treated surgically, non-resectable GEP-NETs have evolved toward targeted therapies, including radioligand therapy. This study describes inpatient resource utilization and inter-regional healthcare mobility for patients with GEP-NETs in Italy, focusing on radioligand therapy.

Methods

We retrieved Italian Hospital Discharge Records (SDO) from 2018 to 2021. Given the absence of specific International Classification of Diseases, Ninth Revision, Clinical Modification codes for GEP-NETs, all potentially related diagnoses were included. Radioligand therapy-related hospitalizations were identified using Diagnosis-Related Group code 409 for radiotherapy, focusing on discharge disciplines of nuclear medicine, radiotherapy, or radiation oncology. We analyzed hospitalization rates by region and regimen and assessed inter-regional mobility using the Attraction and Escape Mobility Indexes.

Results

Over the study period, 4837 radioligand therapy-related GEP-NET hospitalizations were recorded, with 2942 involving the targeted disciplines. Hospitalizations increased by 48.4%, mainly owing to growth in short-stay (0–1 day) discharges (from 37 in 2018 to 228 in 2021), while longer stays (≥ 2 days) rose from 552 to 644. Day hospital accounted for only 0.2% of cases. Regional disparities were prominent, with Emilia-Romagna, Lombardia, and Sicilia managing 88.9% of cases; ten regions recorded no hospitalizations, reflecting a high mobility index (45.8%) and significant inter-regional patient mobility.

Conclusions

The study underscores the need for regulatory adjustments, resource allocation improvements, and healthcare system adaptations to effectively support innovative therapies for GEP-NETs. Addressing these needs is essential to optimize patient outcomes and address regional disparities in Italy’s healthcare system.
