Thus, the utility and limitations of biopsy procedures for the diagnosis of metastatic bone and soft tissue tumors have remained unclear [9]. In the current study, we conducted a retrospective analysis using data of patients treated at our department for bone or soft tissue metastases, wherein ...
Esophageal, gastric and pancreatic cancers represent lethal solid tumors and endoscopic biopsies are the main tool for the histological characterization of these cancer. However, there are many problems for tissue biopsy, together with possible surgical complications, tumor diffusion, and incorrect and/or...

Decision for initial site of approach depends on the lesion. Biopsies can be obtained. Therapeutic interventions can be done.Complications like perforation, mucosal tears and bleeding. Invasive procedure, may require dilatation of upper esophageal sphincter (spiral enteroscopy). ...
Liquid biopsy is a minimally invasive method that uses biofluid samples instead of tissue samples for cancer diagnosis. Exosomes are small extracellular vesicles secreted by donor cells and act as mediators of intercellular communication in human health
Most cases of esophageal cancer can be prevented if detected early at the precancerous high-grade dysplasia stage in patients presenting with Barrett's esophagus, a condition that almost always precedes this form of cancer. Here, Qiu and colleagues have
tissue biopsy, the gold standard for GC screening, is a relatively expensive and invasive procedure with varying degrees of patient harm; a single biopsy does not typically reflect the heterogeneity of GC patients, and the sensitivity and specificity of this method are low due to tissue resection...
Apart from esophageal motor abnormalities, which are highly common and cause troublesome dysphagia, there has not been much focus on gastro-intestinal tract involvement in IIM. However, it is clear from small case series that some few patients develop severe GI complications, such as intestinal ...
(cancer of the esophagus), the protocol requires that a biopsy be taken every 5-20 mm. The repetition of the sampling can be tedious and time consuming. The biopsy device10according to the invention permits the sampling of the esophageal tissue about the circumference of the esophagus in a ...
