Introduction: A precise preoperative tumor monitoring method that reflects tumor burden during neoadjuvant treatment is required to guide individualized perioperative treatment strategies for esophageal squamous cell carcinoma (ESCC). This study examined the clinical significance of preoperative circulating tumor DNA (ctDNA) in the plasma of patients undergoing neoadjuvant chemotherapy (NAC) followed by esophagectomy.
Materials And Methods: Plasma samples were collected longitudinally for ctDNA analysis as well as genomic DNA from primary lesions from patients with histologically confirmed ESCC who received neoadjuvant chemotherapy (NAC) followed by subtotal esophagectomy. Next-generation sequencing was used to identify mutations in both the plasma and primary tumors. We evaluated the relationship between ctDNA alterations and recurrence in patients with locally advanced ESCC.
Results: Pretreatment samples from 25 patients (100 %) showed the same mutations in both ctDNA and primary tumors; therefore, they were classified as ctDNA-positive before treatment. In the cohort of 25 patients analyzed, those who tested positive for ctDNA after NAC had a significantly higher risk of recurrence; the 36-month recurrence-free survival rates were 92 % for ctDNA-negative patients and 8 % for ctDNA-positive patients (p < 0.001).
Conclusions: Preoperative ctDNA status may be a promising prognostic biomarker that can be assessed before surgery in patients with ESCC who received NAC. Expanded cohort validation will allow for more personalized multidisciplinary treatment approaches for ESCC tailored to ctDNA analysis.

Patent ductus venosus is a congenital portosystemic shunt that may cause progressive portal hypertension, hepatic encephalopathy, and focal nodular hyperplasia of the liver. Embolization of the Arantius' duct is the first choice of treatment in infants and children. However, it carries the risk of coil migration into the systemic circulation in adult patients with larger Arantius ducts.

Chronic cerebral artery occlusion is an important cause of cerebral ischemic events. Endovascular recanalization is an effective treatment for this condition, but its success depends on appropriate patient selection and assessment. This is a retrospective study that collected patients with chronic cerebral artery occlusion who underwent endovascular recanalization to determine how imaging features from computed tomography angiography - including the extent of internal carotid artery occlusion, the number of calcified vessels, and the degree of calcification in the occluded vessels - affect the success rate of recanalization.

Background: Coronary artery bypass graft (CABG) surgery is performed in patients with complex multivessel coronary artery disease, but long-term graft occlusion remains a major limitation. The immature surfactant protein type-B (proSP-B) has emerged as a predictor of adverse cardiovascular outcomes.
Objectives: The purpose of this study was to examine the relationship between preoperative plasma proSP-B and graft occlusion 18 months post-CABG.

Introduction: Prostate-specific antigen (PSA), a serine protease primarily expressed in the prostate, has also been detected in hormonally regulated female tissues, including the breast. Some studies suggest a correlation between increased levels of circulating free PSA (fPSA) and breast cancer, but its role remains debated. This study aimed to evaluate this association while minimizing hormonal confounding factors.

Background: Some patients with resectable or borderline resectable pancreatic ductal adenocarcinoma (PDAC) may have distant metastases, undetected on preoperative imaging or early recurrence, within 6 months after surgery. Occult metastases (OMs) must be accurately predicted to optimize multidisciplinary treatment.
Aim: To investigate the efficacy of circulating tumor DNA (ctDNA) in predicting OM.
