Early Recurrence and Omission of Adjuvant Therapy after Pancreaticoduodenectomy Argue against a Surgery-First Approach.

Journal Article (Journal Article)

BACKGROUND: Sequencing therapy for patients with periampullary malignancy is controversial. Clinical trial data report high rates of adjuvant therapy completion, though contemporary, real-world rates remain incomplete. We sought to identify patients who failed to receive adjuvant therapy and those at risk for early recurrence (ER) who might benefit most from neoadjuvant therapy (NT). METHODS: We retrospectively reviewed medical records of 201 patients who underwent pancreaticoduodenectomy for periampullary malignancies between 1999 and 2015; patients receiving NT were excluded. Univariate and multivariate analyses were performed to identify predictors of failure to receive adjuvant therapy and ER (within 6 months) as the primary end points. RESULTS: The median age at the time of surgery was 65.5 years (interquartile range 57-74 years). The majority of tumors were pancreatic ductal adenocarcinoma (76.6 %), and 71.6 % of patients received adjuvant therapy after resection. Univariate predictors of failure to undergo adjuvant therapy were advanced age, age-adjusted Charlson comorbidity index, operative transfusion, reoperation, length of stay, and 30- to 90-day readmissions (all p < 0.05). Advanced age, specifically among patients >70 years, persisted as a significant preoperative predictor on multivariate analysis (p < 0.01). Patients who failed to receive adjuvant therapy and/or developed ER had significantly worse overall survival rates compared to all other patients (27.8 vs. 9.7 months; p < 0.01). CONCLUSIONS: Approximately one-third of surgery-first patients undergoing pancreaticoduodenectomy at our institution did not receive adjuvant therapy and/or demonstrated ER. This substantial subset of patients may particularly benefit from NT, ensuring completion of multimodal therapy and/or avoiding futile surgical intervention.
