- Abstract
Context • Because the early symptoms of primary hepatocellular carcinoma (PHC) aren’t significant, it’s difficult to diagnose it by routine inspection clinically, and if the lesion’s diameter is small, less than 2.0 cm, false negatives can occur in pathological examinations. Researchers need to actively search for more diagnostic methods. Objective • The study intended to detect and analyze the value of plasma Septin9 gene methylation for the diagnosis and therapeutic monitoring of PHC in older adults. Design • The research team performed a prospective controlled study. Setting • The study took place at the First Hospital of Qiqihar, an Affiliated Qiqihar Hospital at Southern Medical University in Qiqihar, China. Participants • Participants were 32 patients with PHC and 28 with cholangiocarcinoma (CCA) who had been admitted to the hospital between January 2021 and July 2022 and 40 healthy individuals. Groups • The research team divided participants into three groups: (1) patients with PHC, the PHC group; (2) patients with CCA, the CCA group; and (3) healthy individuals, the control group. Outcome Measures • The research team: (1) determined the positive expression rate of Septin9 gene methylation; (2) measured liver function indicators—alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum total bilirubin (TBIL), direct bilirubin (DBIL), alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), albumin (ALB); and (3) measured tumor markers—alpha-fetoprotein (AFP), carbohydrate antigen (CA) 199, CA125, and CA153. The team also: (1) established a binary logistic regression model based on levels of GGT and plasma Septin9 gene methylation to analyze risk factors and diagnosis accuracy, (2) created a receiver operating characteristic (ROC) curve to analyze diagnostic values; and (3) during followup, analyzed the negative conversion rate of Septin9 gene methylation in participants. Results • The positive expression rate of Septin9 methylation in the PHC group was significantly lower than that that of the CCA group and significantly higher than that of the control group (P<.05). The PHC group’s ALT, AST, TBIL, DBIL, ALP, and GGT were significantly higher than those of the control group but significantly lower than those of the CCA group (all P < .05). PHC group’s ALB was significantly lower than that of the control group (P<.05). The PHC group’s AFP, CA199, and CA125 were significantly higher than those of the control group, and the PHC group’s CA199 and CA125 were significantly lower than those in the CCA group (all P < .05). The positive expression of Septin9 gene methylation and the high expression of GGT were risk factors for PHC (OR>1, P < .05). The AUC of the Septin9 gene methylation, the GGT level, and the combined detection of both variables (all AUC > 0.70), suggests that the variables have a diagnostic value in the detection of PHC, with the combined detection having the highest value. The negative conversion rate after surgery of Septin9 gene methylation was 87.10%, for 27 out of 31 participants in the PHC and CCA groups (χ² = 29.405, P<.001). Conclusion • Plasma Septin9 gene methylation is a sensitive molecular marker for the diagnosis and therapeutic monitoring of older adults with PHC, and combined with the serum GGT level, has a high diagnostic efficiency, which may reflect the treatment status of patients.
