Watchdog or Demagogue? The Media in the Chinese Legal System

PURPOSE: We hypothesized that preoperative tooth loss could predict general health conditions, including inflammation, postoperative complications (POCs), and overall survival (OS), in patients with colorectal cancer (CRC) and other gastrointestinal cancers. METHODS: Data of patients who underwent curative surgical resection for CRC during 2017-2021 at our hospital were retrieved. The primary outcomes were POCs, whereas the secondary endpoint was OS. According to the Japanese database, patients within each age range with more than the age-adjusted average number of teeth were classified as the Oral N (normal) group, whereas those with less than the age-adjusted average number of teeth were classified as the Oral A (abnormal) group. The relationship between tooth loss and POCs was assessed using a logistic regression model. RESULTS: Overall, 146 patients were enrolled, with 68 (46.6%) and 78 (53.4%) patients in the Oral N and A groups, respectively. In the multivariate analysis, the Oral A group was an independent risk factor for POCs [hazard ratio (HR), 5.89; 95% confidence interval (CI), 1.81-19.1; p < 0.01]. Similarly, univariate analysis revealed that the Oral A group tended to be associated with OS (HR, 4.57; 95% CI, 0.99-21.2; p = 0.052), but the association was not statistically significant. CONCLUSION: In CRC patients who underwent curative resection, tooth loss was a predictor of POCs. Although further investigations are needed, our results support the use of tooth loss as a simple and essential preoperative evaluation system.
