Studiepopulasjon

Patients with evidence of a GEP-NET diagnosis between 01 January 2018 and 31 December 2025 and initiating a 1L treatment during this time period.

Beskrivelse

Inclusion criteria:

  1. Patients with ≥1 International Classification of Diseases Clinical Modification, 10th revision (ICD-10-CM) diagnosis code for GEP-NET between 01 January 2018 and 31 December 2025. The date of the first such claim will be defined as the diagnosis date.
  2. Initiation of first-line (1L) systemic therapy (i.e., somatostatin analogs [SSAs], targeted therapy, peptide receptor radionuclide therapy [PRRT], chemotherapy) indicated for GEP-NET on or after the date of diagnosis. The date of treatment initiation will be defined as the index date.
  3. Patients ≥18 years of age on the index date

  4. Patients with ≥12 months (360 days) of continuous data availability (proxy for continuous health plan enrollment) prior to the index date, defined as:

    1. ≥1 medical and pharmacy claim >12 months prior to the index date; AND
    2. ≥1 medical and pharmacy claim within the first 6 months of the 12-month period prior to the index date; AND
    3. ≥1 medical and pharmacy claim during the last 6 months of the 12-month period prior to the index date; AND

  5. Patients with ≥1 month (30 days) of continuous data availability (proxy for continuous health plan enrollment) following the index date, defined as:

    1. ≥ 1 pharmacy dispensing a GEP-NET treatment at any time during the post-index period, including the index date, reports data during the first month following the index date
    2. ≥ 1 provider prescribing a GEP-NET treatment at any time during the post-index period, including the index date, reports data during the first month following the index date

Exclusion criteria:

  1. Patients with evidence of GEP-NET prior to the diagnosis date within the study period
  2. Patients with evidence of GEP-NET treatment prior to the index date within the study period
  3. Patients with missing or invalid age or sex
  4. Patients with other primary malignancies during the 12-month pre-index period
  5. Patients with invalid death date (i.e., death date ≤ index date)

Baseline
NCI Comorbidity Index Score
Tidsramme: Baseline
The NCI comorbidity index is a tool used to measure the risk of non-cancer deaths for cancer patients based on the presence and severity of other health conditions. It includes 14 conditions identified using administrative data diagnosis and procedure codes. The index excludes solid tumors, leukemias, and lymphomas as comorbid conditions. Each condition is assigned a score (from 1 to 6) based on how serious it is and patient scores are summed to give a final overall score. A high score indicates a higher burden of comorbid conditions and possible higher risk of death.
