Purpose: Acute kidney injury is a sentinel event affecting colorectal cancer patients either as a consequence of surgery or systemic chemotherapy. It is highly correlated with both short and long-term adverse outcomes. This work aimed to study the prevalence, risk factors, and impact on survival of postoperative (PO-AKI) and post-chemotherapy (PC-AKI) after colorectal cancer (CRC) surgery in Egyptian patients., Methods: Data of the patients with CRC who underwent surgery over the previous 5 years was retrieved from an internet-based medical system. The incidence of PO-AKI and PC-AKI was calculated, the rate and time to resolution of PO-AKI were recorded, and the possible predictors of AKI were assessed using univariate and multivariate analysis; also, the impact of AKI on patients' survival was tested using survival curves., Results: Five hundred sixty-one cases fulfilled the inclusion criteria and were included in the study. PO-AKI was detected in 10.5% of the patients. Significant risk factors included intraoperative hypotension, sepsis, hypoalbuminemia, amount of intraoperative bleeding, neoadjuvant therapy, and preoperative chronic kidney disease (CKD). However, only neoadjuvant treatment (hazard ratio (HR) 2.2) and CKD (HR 3.3) maintained significant risk in the multivariate analysis. PC-AKI was observed in 18.7% of the patients treated. Significant risk factors were previous CKD and the chemotherapy type, mainly affecting those who received Irinotecan-based therapy. The hazard ratio was 8.5 and 2.4 respectively, in multivariate analysis. The overall survival was significantly worse in those who developed PO- or PC-AKI (p < 0.001)., Conclusion: AKI affects more than 25% of CRC patients after surgery and/or chemotherapy. Modifiable risk factors include preoperative hypoalbuminemia, intraoperative bleeding, and/or intraoperative hypotension. While, the more important risk factors were non-modifiable including CKD, neoadjuvant therapy, and Irinotecan-containing regimens. Most kidney injuries are stage I; however, they are associated with shorter overall survival., Competing Interests: Declarations.

Background: Stomach cancer is a curative disease in early stages. The optimal extent and approach for gastric resection are still evolving., Patients and Methods: In this study, we examined the value, as well as, the predictors of omental disease spread, retrospectively, in a group of patients with gastric cancer who attended the Oncology Center, Mansoura University, in the period between January 2006 and April 2017., Results: Nodal metastasis, especially heavy disease (N 2 and beyond), and advanced stage are predictors of the presence of omental disease. However, neither overall nor disease-free survival is affected by omental infiltration., Conclusion: Omental resection will continue being an integral part of gastric resection, but the level of omental cutting needs further studies.
