However, a small propor- tion of patients fail to bene t from the ERAS program following pancreaticoduodenectomy. This study aimed to identify the risk factors associated with failure of ERAS program in pancreaticoduodenectomy. Methods: Between May 2014 and December 2017, 176 patients were managed with ERAS program fol-lowing pancreaticoduodenectomy. ERAS failure was indicated by prolonged hospital stay, unplanned read- mission or unplanned reoperation. Demographics, postoperative recovery and compliance were compared of those ERAS failure groups to the ERAS success group. Results: ERAS failure occurred in 59 patients, 33 of whom had prolonged hospital stay, 18 were readmitted to hospital within 30 days after discharge, and 8 accepted reoperation. Preoperative American Society of Anesthesiologists (ASA) score of ≥III (OR = 2.736;95% CI: 1.276 6.939;P=0.028) and albumin (ALB) level of <35g/L (OR=3.589;95% CI: 1.403 9.181;P=0.008) were independent risk factors associated with prolonged hospital stay. Elderly patients (>70 years) were on a high risk of unplanned reoperation (62.5% vs. 23.1%, P=0.026). Patients with prolonged hospital stay and unplanned reoperation had delayed intake and increased intolerance of oral foods. Prolonged stay patients got off bed later than ERAS success patients did (65h vs. 46h, P =0.012). Unplanned reoperation patients tended to experience severer pain than ERAS success patients did (3 score vs. 2 score, P =0.035). Conclusions: Patients with high ASA score, low ALB level or age >70 years were at high risk of ERAS failure in pancreaticoduodenectomy. These preoperative demographic and clinical characteristics are important determinants to obtain successful postoperative recovery in ERAS program.展开更多

Specific inhibitors of oncogenic signaling pathways andtumor-associated angiogenesis can activate the anti-tumor immune responses byincreasing tumor antigen presentation or intratumor T cell infiltration. Additionalinsights into the effects and mechanisms of targeted therapies on the induction ofanti-tumor immunity will facilitate development of rational and effective combinationstrategies that synergize rapid tumor regression and durable response. Inthis review, we have summarized the recent combinations of targeted therapiesand immunotherapies, along with the associated clinical challenges.展开更多
