Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

Objective:To explore the influencing factors of early death (within 3 months) in adult glioma patients, and to construct a risk prediction model.Methods:Retrospective analysis was performed on the clinical data of 228 adult glioma patients admitted to the 909th Hospital (Dongnan Hospital of Xiamen University) from June 2020 to June 2024. Patients were divided into a death group ( n=32) and a survival group ( n=196) based on whether death occurred within 3 months, and the clinical data between the two groups were compared. Multivariate logistic regression was used to analyze the influencing factors of death within 3 months, a logistic regression prediction model was constructed, and receiver operator characteristic (ROC) curve was plotted to analyze the predictive value of the model. Results:There were no statistically significant differences between the two groups in age, gender, hypertension, diabetes, tumor location, tumor involvement, neurological impairment, maximum tumor diameter, chemotherapy, or radiotherapy (all P>0.05). The death group showed higher proportions of cerebral herniation ( χ2=20.74, P<0.001), hospital admission Karnofsky performance status (KPS) score ≤70 ( χ2=26.66, P<0.001), tumor grade Ⅲ-Ⅳ ( χ2=28.70, P<0.001), MGMT promoter unmethylation ( χ2=10.25, P=0.001), IDH wild-type ( χ2=6.18, P=0.013), and incomplete tumor resection ( χ2=10.37, P=0.001) compared with the survival group. Multivariate analysis revealed that cerebral herniation ( OR=19.78, 95% CI: 5.33-73.41, P<0.001), hospital admission KPS score ≤70 ( OR=19.64, 95% CI: 5.54-69.59, P<0.001), tumor grade Ⅲ-Ⅳ ( OR=9.40, 95% CI: 3.02-29.27, P<0.001), MGMT promoter unmethylation ( OR=4.28, 95% CI: 1.18-15.54, P=0.027), and incomplete tumor resection ( OR=9.50, 95% CI: 2.72-33.23, P<0.001) were independent risk factors for early death in glioma patients. The risk prediction model for early death in glioma patients constructed based on these indicators was logit ( P) =-18.04+2.96×cerebral herniation (with=1, without=0) +2.98×hospital admission KPS score (≤70=1, >70=0) +2.24×tumor grade (Ⅲ-Ⅳ=1, Ⅰ-Ⅱ=0) +1.45×MGMT promoter methylation (no=1, yes=0) +2.25×complete tumor resection (no=1, yes=0). ROC curve analysis demonstrated that this model had predictive value for early death in glioma patients, with an area under the curve of 0.920 (95% CI: 0.868-0.972), a sensitivity of 0.842, and a specificity of 0.906. Conclusions:Cerebral herniation, hospital admission KPS score ≤70, tumor grade Ⅲ-Ⅳ, MGMT promoter unmethylation, and incomplete tumor resection are independent risk factors for early death in adult glioma patients. The risk prediction model constructed based on these indicators has good predictive value.

Objective:To investigate the effect of cancer nodules on postoperative liver metastasis in patients undergoing radical resection of colorectal cancer.Methods:The clinicopathological data of 196 patients undergoing radical operation for colorectal cancer admitted to the Dongnan Hospital of Xiamen University from January 2019 to June 2020 were retrospectively analyzed. According to the pathological results, they were divided into cancer nodule group and non-cancer nodule group. Time and the number of liver metastasis during the follow-up period were analyzed. The relationship between cancer nodules and clinicopathological features was analyzed, and the influencing factors of postoperative liver metastasis in patients with colorectal cancer were analyzed by univariate and logistic multivaiate analysis. The receiver operator characteristic (ROC) curve was drawn to analyze the predictive effect of cancer nodule diameter on postoperative liver metastasis of colorectal cancer.Results:There were 50 patients accompanied by cancer nodules in 196 patients with colorectal cancer, the incidence rate was 25.5%, the diameter of cancer nodules was 0.4-1.8 cm, the median diameter was 1.0 cm, and there were 46 patients with liver metastasis, the incidence rate was 23.5%. There were statistically significant differences in carbohydrate antigen CA19-9 ( χ2=7.55, P=0.006), maximum tumor diameter ( χ2=12.23, P<0.001), T stage ( χ2=15.79, P<0.001), vascular thrombus ( χ2=12.79, P<0.001), lymph node metastasis ( χ2=16.18, P<0.001) between the cancer nodule group and the non-cancer nodule group. Univariate analysis showed that CA19-9 ( χ2=7.40, P=0.007), maximum tumor diameter ( χ2=8.23, P=0.004), T stage ( χ2=4.58, P=0.032), vascular cancer thrombus ( χ2=12.97, P<0.001), lymph node metastasis ( χ2=3.96, P=0.047), cancer nodules ( χ2=67.60, P<0.001), cancer nodule diameter ( t=4.28, P<0.001), and the number of cancer nodules ( χ2=68.77, P<0.001) were all influential factors for postoperative liver metastasis in colorectal cancer patients. Multivariate analysis showed that stage T 3-4 ( OR=4.62, 95% CI: 1.51-7.35, P=0.003), vascular cancer thrombus ( OR=5.42, 95% CI: 1.75-12.85, P<0.001), accompanied by cancer nodules ( OR=18.54, 95% CI: 7.45-39.73, P<0.001), the diameter of cancer nodules ( OR=13.20, 95% CI: 4.74-29.64, P<0.001), number of nodules [one cancer nodule ( OR=9.11, 95% CI: 2.24-27.34, P<0.001), two cancer nodules ( OR=6.36, 95% CI: 1.38-9.08, P<0.001) and three cancer nodules ( OR=5.00, 95% CI: 1.98-8.84, P<0.001) ] were independent influencing factors for postoperative liver metastasis in patients with colorectal cancer. ROC curve analysis showed that the best threshold of the diameter of cancer nodules for predicting liver metastasis was 1.1 cm [area under the curve (AUC) =0.764, 95% CI: 0.632-0.896, P=0.002). The incidence of liver metastasis in patients with cancer nodules diameter≥1.1 cm was 95.65% (22/23), higher than that in patients with cancer nodules diameter<1.1 cm (40.74%, 11/27), with a statistically significant difference ( χ2=16.69, P<0.001) . Conclusion:Patients with colorectal cancer with cancer nodules≥1.1 cm in diameter should be vigilant against postoperative liver metastasis.

OBJECTIVE: To investigate the long-term outcome of laparoscope-assisted transanal total mesorectal excision (taTME) for rectal cancer. METHODS: Clinicopathological data of 29 patients with mid-low rectal cancer undergoing laparoscope-assisted taTME at Department of Gastrointestinal Surgery, the First Affiliated Hospital of Guangzhou Medical University from May 2010 to December 2015 were collected for the retrospective case-series study. All the operations were performed with transabdominal and transanal procedure simultaneously or sequentially. Perioperative presentations, pathological examinations, and oncologic outcomes were retrospectively analyzed. Long-term recurrence, metastasis and survival were assessed during follow-up. Outpatient clinic and telephone survey were used for follow-up. The follow-up time ended in December 2018. The overall survival (OS) rate and disease-free survival (DFS) rate were calculated by the Kaplan-Meier method. RESULTS: The average intra-operative blood loss was (75.9±9.5) ml (range,20 to 200). The average operating time was (223.6±4.1) minutes (range, 165 to 280). The average number of harvested lymph node was 22.3±2.0. The average length of pathological specimen was (13.1±0.6) cm. The average distal resection margin was (2.9±0.2) cm. 89.7% (26/29) of specimens was complete and 10.3% (3/29) near complete. Two cases (6.9%) had positive cutting circumferential margin. Median follow-up was 56 (range, 22 to 91) months. Local recurrence rate, distant metastasis rate, 3-year OS rate, 3-year DFS rate, 5-year OS rate, 5-year DFS rate were 10.3% (3/29), 20.7%(6/29), 96.6%, 83.2%, 87.6% and 79.6%, respectively. No incisional hernia or adhesive intestinal obstruction was found. CONCLUSION Long-term outcomes of mid-low rectal cancer patients undergoing laparoscope-assisted taTME are satisfactory.
