Abstract
BACKGROUND: Peritoneal dissemination of small bowel adenocarcinoma (SBA) is rare but is associated with a dismal prognosis. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a promising treatment option. We evaluated our experience of CRS-HIPEC for the treatment of SBA. PATIENTS AND METHODS: Sixteen consecutive patients underwent CRS-HIPEC for small bowel malignancy between 2003 and 2016. Clinopathological and treatment-related factors were obtained from a prospective database. The study's endpoints of disease-free (DFS) and overall (OS) survival were evaluated using the Kaplan-Meier method. Prognostic variables were identified through univariate and multivariate analyses. RESULTS: Follow-up was complete in all patients. The median follow-up was 20.6 (range=0.2-62) months. The was no in-hospital mortality and grade III/IV morbidity was 25%. The median OS after CRS-HIPEC was 24.7 months, with a 36-month survival of 34%. The median DFS was 11.3 months, with a 36-month DFS of 8%. Two factors were associated with a poorer OS on univariate analysis; only peritoneal cancer index >10 was associated with a poorer OS on multivariate analysis (p=0.032). CONCLUSION: CRS-HIPEC in selected patients with peritoneal dissemination of SBA is associated with reasonable mid-term survival outcomes but treatment failure is common. High disease burden, quantified by the PCI is associated with poor outcomes. A large, prospective, multi-institutional study is needed to further evaluate the outcomes of CRS-HIPEC for SBA. Copyright
