Background: Baculoviral inhibitor of apoptosis repeat-containing 5 (BIRC5) gene is an inhibitor of apoptosis that expresses in human embryonic tissues but it is absent in most healthy adult tissues. The copy number of BIRC5 has been indicated to be highly increased in tumor tissues; however, its association with the age of onset in breast cancer is not well understood. Methods: Forty tumor tiss...

The clinical significance of tumor markers after radical gastrectomy has not been well characterized. The purpose of this study is to evaluate the prognostic value of early postoperative tumor marker normalization in N3 stage gastric cancer (GC) patients. A total of 259 N3 stage GC patients with preoperatively elevated carcinoembryonic antigen (CEA, >5 ng/mL) or carbohydrate antigen 19-9 (CA19-...

aim : this study evaluated the results and efficacy of serum ca 19-9 in determining the nature of a pancreatic solid mass in patients referred for investigation of possible malignancy. background : a wide variety of tumor markers have been proposed for pancreatic cancer but currently the only one with any practical usefulness for diagnosis, prognosis, and monitoring of treatment is “ca 19-9 ”. ...

In this paper we present an accurate technique for automatic detection of fiducial markers in 3d brain images so that fully automatic landmark-based coregistration can be implemented. In our tests, our approach detected successfully 429 out of 430 fiducial markers that can be recognized by human eyes. Thus, in landmarkbased image-registrations, our template-based technique can eliminate the pro...

Objective(s): Interleukin-12 (IL-12) as a cytokine has been proved to have a critical role in stimulating the immune system and has been used as immunotherapeutic agents in cancer gene therapy. Chitosan as a polymer, with high ability of binding to nucleic acids is a good candidate for gene delivery since it is biodegradable, biocompatible and non-allergenic polysaccharide. The objective of the...

PURPOSE The correlation of the respiratory motion of external patient markers and abdominal tumors was examined. Data of this type are important for image-guided therapy techniques, such as respiratory gating, that monitor the movement of external fiducials. METHODS AND MATERIALS Fluoroscopy sessions for 4 patients with internal, radiopaque tumor fiducial clips were analyzed by computer visio...

In addition to histopathological parameters, evaluation of associated hematological factors is essential for devising a sensitive prognostic scale in glioma. Increased neutrophil-lymphocyte ratio (NLR), a marker of systemic inflammatory response, has recently been associated with worse outcome in various cancers. Given that glioma progression is characterized by inflammation, aggressive angioge...

Bladder cancer is one of the most common forms of cancers in the world. The current gold standards for itsdiagnosis are cystoscopy and urine cytology. Cystoscopy, a naked eye assessment of the bladder, is invasive, uncomfortable and costly with a great deal of personal variability in its results; while urine cytology has high specificity but low sensitivity, particularly for low-grade les...

Abstract Immune checkpoint inhibitors (ICI) have revolutionized treatment for various cancers; however, durable response is limited to only a subset of patients. Discovery blood-based biomarkers that reflect dynamic change the tumor microenvironment, and predict ICI, will markedly improve current regimens. Here, we investigate CX3C chemokine receptor 1 (CX3CR1), marker T-cell differentiation, a...
