Importance: A comprehensive review of the evidence exploring the outcomes of enhanced recovery after surgery (ERAS) guidelines has not been completed.

Objective: To evaluate if ERAS guidelines are associated with improved hospital length of stay, hospital readmission, complications, and mortality compared with usual surgical care, and to understand differences in estimates based on study and patient factors.

Data Sources: MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central were searched from inception until June 2021.

Introduction: Iron-deficiency anaemia is common in gynaecological oncology patients. Blood transfusions are immunosuppressive and carry immediate and long-term risks. Oral iron replacement remains the standard of care but requires prolonged treatment courses associated with gastrointestinal side effects, poor compliance and variable absorption in cancer patients.

Objectives: To characterize the effect of transversus abdominis plane (TAP) blocks on post-operative outcomes in patients undergoing laparotomy for gynecologic malignancy.

Methods: This retrospective cohort study assessed patients undergoing laparotomy in 2016-2017 and 2020 in Alberta, Canada. The primary outcome was opioid consumption in oral morphine milligram equivalent (MME).

Objective: To evaluate the safety and the effectiveness of thoracic epidural analgesia as part of the enhanced recovery after surgery (ERAS) multimodal analgesic protocol in patients with gynecologic oncology who have undergone laparotomy for suspected or confirmed malignancy.

Methods: We conducted a prospective cohort study, following an enhanced recovery after surgery pathway, among patients who had undergone laparotomy for confirmed or suspected gynecological malignancy between January 2020 and September 2021. All patients who underwent laparotomy at the gynecologic oncology department for the aforementioned reason during that time were considered eligible.

Enhanced Recovery After Surgery (ERAS) is a global surgical quality improvement program that started in colorectal surgery and has now expanded to numerous specialties, including gynecologic oncology. ERAS guidelines comprise multidisciplinary, evidence-based recommendations in the preoperative, intraoperative, and postoperative period; these interventions broadly encompass patient education, anesthetic choice, multimodal pain control, avoidance of unnecessary drains, maintenance of nutrition, and prevention of emesis. Implementation of ERAS has been shown to be associated with improved clinical outcomes (length of hospital stay, complications, readmissions) and cost.

Background: Treatment of ovarian cancer often requires extensive surgical resection. The transversus abdominis plane (TAP) block has been utilized in benign gynecologic surgery to decrease post-operative pain and opioid use. We hypothesized that TAP blocks would decrease total opioid use in the first 24 hours and decrease length of stay following staging and cytoreductive surgery for ovarian cancer compared with either no local anesthetic or local wound infiltration alone.

Objective: To describe the frequency of clinically significant side effects associated with adjuvant intraperitoneal (IP) carboplatin and intravenous (IV) dose-dense paclitaxel chemotherapy for epithelial ovarian cancer (EOC).

Methods: Patients with stage II to IV EOC who underwent upfront cytoreductive surgery followed by adjuvant IP carboplatin (AUC 6) every 3 weeks with IV paclitaxel weekly at 80 mg/m were included. Side effects and the resulting changes in treatment are presented using univariate analysis and compared to major phase III RCTs.

Invariant natural killer T (iNKT) cells are CD1d-restricted, glycolipid-reactive lymphocytes with potent immunoregulatory characteristics. Although recent years have witnessed intensified interest in iNKT cells, little is known about intracellular signaling pathways that control iNKT cell responses, including those mediated by mitogen-activated protein kinases (MAPKs). We employed selective inhibitors of ERK1/2, JNK and p38 to examine the importance of these MAPKs in iNKT cell responses to the prototype glycolipid antigen alpha-galactosylceramide (alpha GC).
