Meta Analysis
Intraperitoneal chemotherapy for peritoneal metastases of gastric origin: a systematic review and meta-analysis.
Gastric cancer with peritoneal metastases is associated with a dismal prognosis. Normothermic catheter-based intraperitoneal chemotherapy and normothermic pressurized intraperitoneal aerosol chemotherapy (PIPAC) are methods to deliver chemotherapy intraperitoneally leading to higher intraperitoneal concentrations of cytotoxic drugs compared to intravenous administration. We reviewed the effectiveness and safety of different methods of palliative intraperitoneal chemotherapy. ⋯ Repeated intraperitoneal chemotherapy, regardless of method of administration, is safe for patients with gastric cancer and peritoneal metastases. Conversion surgery after completion of the intraperitoneal chemotherapy is possible in a subset of patients.

Ileal pouch-anal anastomosis ('pouch surgery') provides a chance to avoid permanent ileostomy after proctocolectomy, but can be associated with poor outcomes. The relationship between hospital-level/surgeon factors (including volume) and outcomes after pouch surgery is of increasing interest given arguments for increasing centralization of these complex procedures. The aim of this systematic review was to appraise the literature describing the influence of hospital-level and surgeon factors on outcomes after pouch surgery for inflammatory bowel disease. ⋯ This review summarizes the growing body of evidence that supports centralization of pouch surgery to specialist high-volume inflammatory bowel disease units. Centralization of this technically demanding surgery that requires dedicated perioperative medical and nursing support should facilitate improved patient outcomes and help train the next generation of pouch surgeons.

Review Meta Analysis
Predictive value of pretreatment circulating inflammatory response markers in the neoadjuvant treatment of breast cancer: meta-analysis.
Systemic inflammatory response markers have been found to have a prognostic role in several cancers, but their value in predicting the response to neoadjuvant chemotherapy in breast cancer is uncertain. A systematic review and meta-analysis of the literature was carried out to investigate this. ⋯ The present study found the pretreatment neutrophil-to-lymphocyte ratio, white cell count, lymphocyte count, and monocyte count of value in the prediction of a pCR in the neoadjuvant treatment of breast cancer. Further research is required to determine their value in specific breast cancer subtypes and to establish optimal cut-off values, before their adoption in clinical practice.

Hereditary adenomatous polyposis syndromes, including familial adenomatous polyposis and other rare adenomatous polyposis syndromes, increase the lifetime risk of colorectal and other cancers. ⋯ These updated guidelines provide current, comprehensive, and evidence-based practical recommendations for the management of surveillance and treatment of familial adenomatous polyposis patients, encompassing additionally MUTYH-associated polyposis, gastric adenocarcinoma and proximal polyposis of the stomach and other recently identified polyposis syndromes based on pathogenic variants in other genes than APC or MUTYH. Due to the rarity of these diseases, patients should be managed at specialized centres.
