Does minimally invasive pancreaticoduodenectomy increase the chance of a textbook oncologic outcome?

Abstract

Background: Textbook oncologic outcome has been described in an effort to improve upon traditional outcomes defining care after pancreaticoduodenectomy for adenocarcinoma. We sought to examine whether minimally invasive pancreaticoduodenectomy increased the likelihood of an optimal textbook oncologic outcome.

Methods: Patients undergoing open pancreaticoduodenectomy or minimally invasive pancreaticoduodenectomy between 2010 and 2015 were identified in the National Cancer Database. Textbook oncologic outcome was defined as R0 resection with American Joint Committee on Cancer compliant lymphadenectomy, no prolonged duration of stay, no 30-day readmission/mortality, and receipt of adjuvant chemotherapy. Propensity score matching was employed to evaluate adjusted rates of textbook oncologic outcome, in addition to overall survival.

Results: Among 12,854 patients who underwent pancreaticoduodenectomy, 48.3% were female, and the median patient age was 66 years; 87.5% underwent open pancreaticoduodenectomy, and 12.5% underwent whether minimally invasive pancreaticoduodenectomy. After propensity score matching, there were no noted differences in the likelihood of R0 resection, adequate lymphadenectomy, nonprolonged duration of stay, no readmission, no 30-day mortality, adjuvant chemotherapy, or textbook oncologic outcome among open pancreaticoduodenectomy versus minimally invasive pancreaticoduodenectomy (P > .05). Textbook oncologic outcome was associated with an improved median overall survival (negative textbook oncologic outcome: 21.3 months vs positive textbook oncologic outcome: 27.6 months, P < .001).

Conclusion: Although textbook oncologic outcome was associated with a survival advantage, it was only achieved in 1 in 4 patients undergoing pancreaticoduodenectomy for adenocarcinoma. Achievement of textbook oncologic outcome was equivalent among patients who underwent minimally invasive pancreaticoduodenectomy compared with open pancreaticoduodenectomy after propensity score matching.
