ABSTRACT
Postoperative complications of colorectal cancer (CRC) are the main cause of postoperative death and seriously affect the quality of life and survival time of patients. The application of a clinical prediction model for postoperative complications of CRC can help promptly identify high-risk patients. Accordingly, reasonable intervention measures can be actively taken to reduce the incidence of postoperative complications of CRC. A scientific basis can also be provided to improve the prognosis of patients. In this work, literature on the risk-factor analysis and prediction-model construction of postoperative complications of CRC at home and abroad in recent years was collected and reviewed. The evaluation content and efficiency of the clinical prediction models in postoperative complications of CRC were summarized. Their advantages and disadvantages were also analyzed. The purpose of this study was to provide a reference for the subsequent optimization of such models and the development of a strong, clinically practical, and universal risk-screening tool for postoperative complications of CRC.
ABSTRACT
Gastric cancer is a common cancer in digestive system in China. It′s in the forefront of cancer in terms of morbidity and case fatality, posing a great threat to people′s health. With the advent of the era of precision medicine, the treatment of each patient with gastric cancer must follow the principle of individualization. However, individualized treatment is based on the development of biomarkers. Liquid biopsy has been reported to be a biomarker capable of detecting information about tumorigenesis and progression, and has been suggested as a useful tool for personalized treatment. Compared with traditional "tissue biopsy" , liquid biopsy has significant advantages because it is noninvasive and painless, reduces cost and time for diagnosis, and could be used for diagnosis, prognosis, prediction of disease progression, or as a surrogate marker of response to treatment.For this purpose, the author will review the related detection techniques of liquid biopsy and its role in early screening, efficacy evaluation and recurrence monitoring of gastric cancer.
