    Abstract:
    BACKGROUND: Radical antegrade modular pancreatosplenectomy (RAMPS) has been adopted by some surgeons in the treatment of left-sided pancreatic cancer (PDAC). Low disease incidence and heterogenous disease biology make robust prospective comparison of RAMPS and standard distal pancreatosplenectomy (DPS) difficult. METHODS: Consecutive cases of chemo-naïve patients undergoing open RAMPS and DPS for PDAC between 2010-2017 at two international high-volume pancreatectomy centers were compared. Cox proportional hazard modeling was utilized for multivariate analysis. RESULTS: We identified 193 DPS and 253 RAMPS during the study period. DPS was associated with higher rates of median estimated blood loss (500 vs. 300 cc, P<0.001), median total harvested lymph nodes (18 vs. 12, P<0.001) and R0 resection (94.3% vs. 88.9%, P=0.013). There were no differences in rates of postoperative pancreatic fistula (16.5% vs. 17.8%, P=1) or postoperative hemorrhage (5.9% vs. 3.6%, P=0.385) (DPS vs. RAMPS). After controlling for significant clinical pathological parameters, RAMPS was associated with non-superior recurrence-free survival (RFS) (HR 0.29; 95% CI, 0.07-1.27, P=0.101) and overall-survival (HR 1.03; 95% CI, 0.71-1.49, P=0.895) compared with DPS. Similar results were observed in node-positive patients. CONCLUSIONS: RAMPS is safe and effective in the treatment of PDAC, but is not associated with an improvement in either RFS or overall-survival over DPS.
