Textbook oncologic outcomes are associated with increased overall survival in patients with pancreatic head cancer after undergoing laparoscopic pancreaticoduodenectomy

Abstract

BackgroundTextbook oncologic outcomes (TOO) have been used to evaluate long-term oncologic outcomes for patients after pancreaticoduodenectomy (PD) but not laparoscopic pancreaticoduodenectomy (LPD). The aim of the study was to assess the prognostic value of TOO for patients with pancreatic head cancer undergoing LPD and discuss the risk factors associated with achieving TOO.MethodsPatients with pancreatic head cancer who underwent LPD in West China Hospital from January 2015 to May 2022 were consecutively enrolled. TOO was defined as achieving R0 resection, examination of ≥ 12 lymph nodes, no prolonged length of stay, no 30-day readmission/death, and receiving adjuvant chemotherapy. Survival analysis was used to determine the prognostic value of a TOO on overall survival (OS) and recurrence-free survival (RFS). Logistic regression was used to identify the risk factors of a TOO. The rates of a TOO and of each indicator were compared in patients who suffered or not from delayed gastric emptying (DGE).ResultsA total of 44 (25.73%) patients achieved TOO which was associated with improved median OS (TOO 32 months vs. non-TOO 20 months, P = 0.034) and a better RFS (TOO 19 months vs. non-TOO 13 months, P = 0.053). Patients suffering from DGE [odds ratio (OR) 4.045, 95% CI 1.151–14.214, P = 0.029] were independent risk factors for TOO. In addition, patients with DGE after surgery had a significantly lower rate of TOO (P = 0.015) than patients without DGE.ConclusionsAs there were significant differences between patients who achieved TOO or not, TOO is a good indicator for long-term oncologic outcomes in patients with pancreatic head cancer after undergoing LPD. DGE is the risk factor for achieving TOO, so it is important to prevent the DGE after LPD to improve the rate of TOO.
