Patients with atrial septal defect have an increased risk for atrial fibrillation. Increased P-wave dispersion predicts the development of atrial fibrillation. The aim of this study was to determine difference in P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure in childhood. A total of 68 children (the mean age was 7.2 plus or minus 3.3 years; the mean secundum atrial septal defects diameter was 17.3 plus or minus 5.4 millimetres) were evaluated in this study. Transcatheter closure was attempted in 41 children with secundum atrial septal defects, and the defect in 27 patients was closed by surgical techniques. P maximum, P minimum and P dispersion were measured by the 12-lead surface electrocardiography. P maximum, P minimum and P dispersion were found to be similar in patients with pre- and post-procedure (98.0 plus or minus 19.3 versus 95.1 plus or minus 23.0 milliseconds; 68.0 plus or minus 20.8 versus 67.6 plus or minus 24.3 milliseconds, 29.9 plus or minus 11.0 versus 27.1 plus or minus 12.1 milliseconds, respectively). There was no statistical significance in the comparison of P dispersion between the two groups. But in the surgical group, P-wave dispersion was decreased more significantly compared with baseline values (p-value equal to 0.03). In conclusion, there is no P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure of secundum atrial septal defect.
Background and Objectives: HER-2 expression plays a critical role in the biological behavior and treatment of gastric cancer. With the emergence of HER-2-targeted therapies, classification into negative, low, and positive groups has gained clinical importance. The present study focused on assessing the link between HER-2 status and clinical–pathological variables, metastatic involvement, and overall survival (OS) among advanced gastric cancer patients. Materials and Methods: A total of 300 patients with advanced gastric adenocarcinoma were retrospectively analyzed. The mean age of the 300 patients included in the study was 61.8 years, and 70% of them were male. Based on immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), patients were classified as HER-2-negative (IHC 0), HER-2-low (IHC 1+ or 2+/FISH-negative), or HER-2-positive (IHC 3+ or 2+/FISH-positive). Clinicopathological variables, metastatic sites, and OS were compared among groups using Pearson’s Chi-square, Fisher’s exact test, ANOVA, and Kaplan–Meier survival analysis. Results: Significant differences were observed among HER-2 subgroups in pathological subtype (p = 0.006), liver metastasis (p = 0.009), lung metastasis (p = 0.006), and other metastatic sites (p = 0.001). HER-2-positive patients demonstrated higher rates of adenocarcinoma histology and increased liver and lung metastases. In female patients, HER-2 status was significantly associated with lung (p = 0.001) and other metastases (p < 0.001). Median OS for the entire cohort was 9.83 months (95% CI: 8.29–11.36). HER-2-positive patients had a significantly longer OS (15.06 months) compared with HER-2-negative patients (8.73 months; p = 0.039). Conclusions: HER-2 status is an important predictor of metastatic behavior and survival in advanced gastric cancer. HER-2-positive patients display distinct metastatic patterns and improved outcomes, supporting the value of HER-2-targeted therapies. The HER-2-low group may represent a biologically and clinically relevant intermediate subtype requiring further investigation.
Background and Objectives: This study aimed to evaluate the effects of 24 h versus 46 h continuous 5-fluorouracil (5-FU) infusion durations on pathological response, progression-free survival (PFS), and overall survival (OS) in patients with gastric and gastroesophageal junction adenocarcinoma receiving a perioperative FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) regimen. Materials and Methods: A total of 300 patients who received a perioperative FLOT regimen were retrospectively analyzed. The patients were divided into two groups as those receiving 24 h and 46 h continuous 5-FU infusion. Clinicopathological characteristics were compared. Survival analyses were evaluated using the Kaplan–Meier method. Factors affecting pathological response were analyzed by logistic regression, and factors affecting survival were examined by Cox regression analysis. Results: Pathological response rates were found to be significantly higher in patients receiving 46 h 5-FU infusion (multivariate analysis: OR = 2.884; 95% CI: 1.619–5.138; p < 0.001). The probability of pathological response was found to be significantly lower in patients with baseline cT4 and advanced nodal stage. Median OS times were 41.23 months and 33.73 months in the 24 h and 46 h groups, respectively, with no significant difference detected between the groups (p = 0.371). In contrast, median PFS time was significantly longer in the 24 h group (38.47 months vs. 18.00 months; p < 0.001). However, in multivariate analysis, 5-FU infusion duration could not be demonstrated as an independent prognostic factor for PFS. Moderately and poorly differentiated tumors and an increased number of positive lymph nodes were found to be independent risk factors for progression. Conclusions: Although 46 h 5-FU infusion in the perioperative FLOT regimen was associated with a higher pathological response rate, this advantage was not reflected in survival outcomes. It is considered that the observed difference in PFS may stem from the clinicopathological heterogeneity between the groups. Prospective randomized studies are needed to determine the optimal 5-FU infusion duration.
