OBJECTIVE: The serum albumin-globulin ratio (AGR) is associated with malignancy outcomes. However, among patients with rectal cancer (RC) who undergo neoadjuvant chemoradiotherapy (nCRT), the clinical and prognostic significance of the pretreatment AGR is unclear. METHODS: We investigated whether the pre-nCRT AGR can help predict oncological outcomes in patients with RC receiving nCRT. We analyzed 114 patients with RC who received nCRT followed by total mesorectal excision at our institution...

Well-balanced levels of tyrosine phosphorylation, maintained by the reversible and coordinated actions of protein tyrosine kinases (PTKs) and protein tyrosine phosphatases (PTPs), are critical for a wide range of cellular processes including growth, differentiation, metabolism, migration, and survival. Aberrant tyrosine phosphorylation, as a result of a perturbed balance between the activities of PTKs and PTPs, is linked to the pathogenesis of numerous human diseases, including cancer, suggesting that PTPs may be innovative molecular targets for cancer treatment...

BACKGROUND: Due to late diagnosis and resistance to chemotherapy, most patients with cholangiocarcinoma have an unfavorable prognosis. Despite the use of immunohistochemistry (IHC) in clinical routine, differentiation between intrahepatic cholangiocarcinoma (ICC) and secondary adenocarcinomas of the liver is frequently not clear, leading to false diagnosis and treatment decisions. METHODS: Oligonucleotide microarrays (Affymetrix Hu133A©) were used for gene expression analysis of ICC (n = 11) and secondary adenocarcinomas (colorectal metastases; n = 6)...

Squamous cell carcinoma of mucosal sites in the head and neck (HNSCC) is the sixth most common cause of cancer worldwide, and despite advances in conventional management, it still has significant morbidity and mortality associated with both diagnosis and treatment. Advances in our understanding of the biological mechanisms underlying this disease have demonstrated a significant difference between human papillomavirus (HPV)-associated, HPV and tobacco associated, and HPV-negative disease. It remains important to further elucidate the biologic and genetic differences between HPV-associated and tobacco-associated disease, with the aim of earlier diagnosis through screening, and advances in management including the development of novel therapeutic agents...
