The aim of this study is to compare outcomes of enhanced recovery after surgery (ERAS) procedure, involving preoperative, intraoperative and postoperative optimization, with those of conventional treatment procedure in women undergoing laparoscopic surgery for gynecologic cancer or suspected gynecologic cancer. Investigators hypothesize that those patients randomized to the ERAS protocol will have better recovery status, shorter lengths of hospital stay, without increasing readmission rates and complications, compared with traditional treatment.

Over the past two decades, enhanced recovery after surgery (ERAS) has been initiated and developed in colorectal surgery by Kehlet. Studies have demonstrated that ERAS program can reduce length of hospital stay, hospital cost, complications and morbidity and improve the quality of patient recovery in colorectal, urologic, thoracic, orthopedic, and vascular surgeries by randomized trials and meta-analyses. However, the data in gynecologic oncology underwent minimally invasive therapy is scarce. Therefore, the aim of this study is compare outcomes of ERAS procedure with conventional treatment procedure, to provide practical experience and guidance for the treatment of gynecologic cancer in the future.

The study is a single-center randomized control trial (RCT), and 80 cases of gynecological malignancy in Shanghai First Maternity and Infant Hospital from 2018 to 2021 will be enrolled in this research. All patients with a known or suspected gynecologic malignancy scheduled for laparoscopic surgery will be screened for study eligibility. Those eligible for the study will be approached for participation in the study and provided written informed consent. The randomization sequence of group allocation by means of computer-generated random numbers was generated by an independent statistician from Tongji University.

For ERAS group, patients would receive an optimized preoperative, intraoperative and postoperative care, including extensive preoperative counselling, no mechanical bowel preparation, nonselective NSAIDs premedication, no preoperative fasting but with preoperative carbohydrate loading, tailored anaesthesiology, non-opioid pain management, early removal of urinary catheter, early postoperative feeding and mobilization, and postoperative antiemetic and analgesia management. For control group, patients would receive standard conventional procedure. After meeting the discharge criteria, patients would discharge and additionally follow-up in gynecologic oncology clinic at 2 weeks and 6 weeks postoperatively.

Primary outcome measure of the study involves operation length(h), intraoperative blood loss(mL), intraoperative fluid transfusion units(mL), intraoperative urinary volume(mL), intraoperative blood transfusion(mL), postoperative vital signs, Visual Analog Score (VAS) scale, Post Operative Nausea And Vomiting (PONV) status, first exhaust defecation time, ambulation, length of stay, hospitalization expense, albumin and prealbumin, and postoperative complications. Apart from clinical outcomes, the immunological indicators will also be assessed, consist of WBC, neutrophil count (NEUT), C-Reactive Protein (CRP), CD3+ T cells, CD4+ T cells, CD8+ T cells, CD4+/CD8+ T cells preoperatively, and on post-operative day 1(POD1), POD3, POD5. In addition, the anxiety and sleep quality indicators were analyzed by questionnaire preoperatively and POD5.

For statistical analyses, categorical variables were described using counts and frequencies, and quantitative variables were described using mean, medians and ranges. Patients' characteristics and distribution were compared with MannWhitney U and χ2 tests. The level of statistical significance was set at P\< 0.05. Statistical analyses were carried out with the SPSS 20.0.
