Introduction:
Small bowel adenocarcinomas (SBAs) are rare cancers that have a distinct clinical characteristic and genetic profile. The only potentially curative treatment for localized SBAs is surgery, and treatment options are limited for patients in the advanced stage of disease.
Patient Concerns:
A 39-year-old woman presented in October 2015 with a complaint of persistent vomiting for 8 months.
Diagnosis:
The patient had obstruction caused by a 3 × 2 cm mass at the ascending part of the duodenum and suspected metastasis in the right adnexal region. Postoperative pathology showed a moderately differentiated adenocarcinoma with serosal invasion. The diagnosis was stage IV duodenum adenocarcinoma with right adnexal metastasis.
Interventions:
After the failure of multi-line treatment with chemotherapy and targeted therapy, she was treated with the immune checkpoint inhibitor nivolumab plus regorafenib.
Outcomes:
Disease control lasted for 15 months with markedly improved symptoms.
Conclusion:
To the best of our knowledge, this is the first case of small bowel adenocarcinoma that has been treated with nivolumab combined with regorafenib. This case highlights the potential efficacy of combining nivolumab and regorafenib in the treatment of SBAs.
Insights
This case study shows that combining nivolumab and regorafenib may effectively treat advanced small bowel adenocarcinoma (SBA). This combination therapy provided 15 months of disease control and symptom improvement in a patient with stage IV disease.
Area of Science:
- Oncology
- Gastroenterology
- Immunotherapy
Background:
- Small bowel adenocarcinomas (SBAs) are rare gastrointestinal cancers with limited treatment options for advanced stages.
- Surgery is the only potentially curative option for localized SBAs.
Observation:
- A 39-year-old woman presented with symptoms of duodenal obstruction due to a large mass.
- Diagnosis was stage IV duodenum adenocarcinoma with metastasis to the right adnexal region.
Findings:
- The patient received nivolumab (immune checkpoint inhibitor) plus regorafenib after failing multiple lines of therapy.
- This combination achieved 15 months of disease control with significant symptom improvement.
Implications:
- This is the first reported case of advanced SBA treated with nivolumab and regorafenib.
- The findings suggest this combination therapy holds potential for treating advanced small bowel adenocarcinomas.
