We investigated the clinical significance of CTCs in cancer progression by detecting multiple cancer driver genes associated with epithelial-to-mesenchymal transition (EMT) at the transcript level. The 10-gene panel, comprising , , , , , , , , , and , was established for characterizing CTCs from mouse ESCC xenograft models and clinical ESCC peripheral blood (PB) samples. Correlations between gene expression in CTCs from PB samples ( = 77) and clinicopathological features in ESCC patients ( = 55) were examined.

Objective: To examine whether circulating tumor DNA is clinically useful as a prognostic biomarker for ESCC recurrence and patient survival.
Background: Vocal cord paresis (VCP) is a serious complication after esophagectomy. Conventional diagnosis of VCP relies on flexible laryngoscopy (FL), which is invasive. Laryngeal ultrasonography (LUSG) is non-invasive and convenient.

Peripheral blood (PB) ( = 389) and azygos vein blood (AVB) ( = 13) samplings were recruited prospectively from 88 ESCC patients undergoing curative surgery from 2017 to 2022. Longitudinal CTC enumeration was performed with epithelial (EpCAM/pan-cytokeratins/MUC1) and mesenchymal (vimentin) markers at 12 serial timepoints at any of the pre-treatment, all of the post-treatments/pre-surgery, post-surgery follow-ups for 3-year, and relapse.

We hypothesise that development of synchronous ESCC/HPC depends on multicentricity or independent origin, rather than multifocality due to local or lateral spreading.
Method: Multiple region whole-exome sequencing (M-WES) and clonality analysis were used to assess clonal relationship and spatial inter- or intra-tumour heterogeneity (ITH) in 62 tumour regions from eight dual ESCC/HPC and ten ESCC patients.
Balkan endemic nephropathy (BEN) is a multifactorial environmental disease, with chronic exposure to aristolochic acids (AAs) through AA-contaminated food being one of the major etiological mechanisms. However, the bulk of previous research has only focused on investigating the possible roles of individual pollutants in disease development and the etiological mechanism of BEN remains controversial. In this study, we investigated the exposure concentration and duration dependence of coexposure to phthalate esters and lignite coal-derived phenol and polycyclic aromatic hydrocarbons (PAHs) on the metabolism and DNA adduct formation of aristolochic acid I (AAI).

Due to the traditional practice of herbal medicine and AA-containing plants being used extensively as medicinal herbs, over 100 million East Asians are estimated to be at risk of AA poisoning. Given that the chronic nephrotoxicity of AAs only manifests itself after decades of exposure, early diagnosis of AA exposure could allow for timely intervention and disease risk reduction.

The survival advantage imparted is especially impressive for oesophageal squamous cell carcinoma (OSCC). This study aimed at investigating the efficacy of the CROSS regimen in real-world scenario.

This study aimed to examine the impact that ECE of lymph node has on prognosis for patients with adenocarcinoma of the stomach.
Methods: The study analyzed 321 consecutive patients with gastric cancer who underwent radical gastrectomy between January 2008 and December 2015.
Aristolochic acids (AAs) have been known as potent nephrotoxins since the use of AA-containing herbal medicines was linked with a series of sporadic renal fibrotic nephropathy cases, and yet an estimated 100 million people worldwide are still at risk today because of continued use of similar medicines. However, a similar nephropathic condition is endemic in the rural Balkan regions (e.g.

Whether minimally invasive methods result in equivalent or superior outcome to open esophagectomy or not is still controversial.
