Background: Pancreaticoduodenectomy (PD) with right hemicolectomy (RH) to treat locally advanced right colon cancer (LARCC) has been rarely reported in the literature. Herein, we characterize clinicopathologic factors and evaluate outcomes of en bloc PD and RH for LARCC.
Methods: A systematic review of the literature was conducted on PubMed using MeSH terms ("pancreaticoduodenectomy" or "pancreas/surgery" or "duodenum/surgery" or "colectomy") and ("colonic neoplasms"). Data was extracted from patients who underwent en bloc PD and RH for LARCC. Factors investigated included patient demographics, surgical and pathologic parameters, postoperative complications, disease recurrence, and survival.
Results: Our search yielded 27 articles (106 patients), including 1 case from our institution. Most patients were male (62.1%), median age 58 years (range 34-83). Surgical procedures performed included en bloc RH with PD (n = 91, 85.8%) and en bloc RH with pylorus-preserving PD (n = 15, 14.2%). Among reported, 95.5% of patients (n = 63), underwent R0 resection. One or more complications were reported in 33 patients (52.4%). Median survival was 168 months. Survival after resection was 75.9% at 2 years and 66.3% at 5 years. Overall survival was greater in patients with no lymph node involvement (IIC versus IIIC, hazard ratio 8.4, P = .003). Five-year survival for patients was 84.9% in patients with stage IIC versus 46.4% in patients with stage IIIC. There were 3 postoperative mortalities.
Conclusion: This data demonstrates that en bloc PD and RH is rarely performed yet can be a potentially safe treatment option in patients with LARCC. Lymph node involvement was the only independent prognostic factor.
