BACKGROUND: As small-bowel adenocarcinoma (SBA) is scarce, no standard systemic regimen in metastatic disease has been defined.
OBJECTIVE: To obtain insights into the use and effects of palliative chemotherapy in patients with metastatic SBA in a population-based setting.
METHODS: Data from the Netherlands Cancer Registry of patients with metastatic SBA between 2007 and 2016 were used (n = 522). For patients treated with palliative chemotherapy, differences in treatment regimens and survival were evaluated.
RESULTS: Palliative chemotherapy was received by 38% of patients (n = 199). First-line combination chemotherapy was administered to 80% of patients, mainly CAPOX/FOLFOX. Single-agent chemotherapy mostly consisted of capecitabine. Second-line treatment, mostly irinotecan-based (58%), was prescribed to 27% of patients. Age 70 years or older was an adverse predictive factor for receiving first-line combination chemotherapy (odds ratio (OR) 0.2, 95% confidence interval (CI) 0.08-0.62) and second-line therapy (OR 0.3, 95% CI 0.10-0.72). Median overall survival with palliative chemotherapy was 9.3 months, compared with 3.0 months without. In subanalyses, patients who received only first-line treatment had a median overall survival of 5.6 and 7.0 months after single-agent and combination chemotherapy, respectively.
CONCLUSION: A minority of patients were treated with palliative chemotherapy. First-line treatment consisted predominantly of oxaliplatin-based combination chemotherapy, whereas second-line treatment was mainly irinotecan-based. Population-based median overall survival for selected patients treated with chemotherapy amounted to nine months.
