METHODS A retrospective analysis of 1383 cases with CRC was performed following radical surgery. SII was calculated with the formula SII =(P × N)/L, where P, N, and L refer to peripheral platelet, neutrophil, and lymphocyte counts, respectively. The clinicopathological features and follow-up data were evaluated to compare SII with other systemic inflammation-based prognostic indices such as the neutrophil-lymphocyte ratio(NLR) and platelet-lymphocyte ratio(PLR) in patients with CRC.RESULTS The optimal cut-off point for SII was defined as 340. The overall survival(OS) and disease-free survival(DFS) were better in patients with low NLR, PLR, and SII(P < 0.05). The SII was an independent predictor of OS and DFS in multivariate analysis. The area under the receiver-operating characteristics(ROC) curve for SII(0.707) was larger than those for NLR(0.602) and PLR(0.566). In contrast to NLR and PLR, SII could effectively discriminate between the TNM subgroups. CONCLUSION SII is a more powerful tool for predicting survival outcome in patients with CRC. It might assist the identification of high-risk patients among patients with the same TNM stage.展开更多

We depict a 41-year-old man who underwent sigmoid colon cancer radical surgery followed by adjuvant chemotherapy for alocally ulcerative sigmoid adenocarcinoma with metachronous bilateral adrenal metastasis revealed by a computed tomography scan. histopathological examination showed adenocarcinoma, compatible with metastasis from the rectal cancer. the level of serum carcinoembryonic antigen had indicative significance for the presence of adrenal metastasis in the reported series. We performed a literature analysis related to this pathological characteristic and attach importance to consistent, vigilant radiological surveillance of the adrenal glands in the patients' follow up for colorectal cancer with or without subsequent adrenal metastasis.展开更多
