Colorectal sessile serrated adenomas (SSA) are hypothesized to be precursor lesions of an alternative, serrated pathway of colorectal cancer, abundant in genes with aberrant promoter DNA hypermethylation. In our present pilot study, we explored DNA methylation profiles and examined selected gene mutations in SSA. Biopsy samples from patients undergoing screening colonoscopy were obtained during endoscopic examination. After DNA isolation and quality analysis, SSAs (n = 4) and healthy controls (n = 5) were chosen for further analysis...

Osteosarcoma is the most common primary malignant bone tumor both today and in antiquity. Nevertheless, it is a comparatively rare tumor. This paper describes a case of a highly aggressive craniofacial lesion from the 11th-12th centuries AD, most likely representing osteosarcoma. During the paleopathological study, macroscopic, endoscopic, radiological, scanning-electron and light microscopic investigations were performed. The skull of the approximately 40-50 year-old female revealed several pathological findings...

Disruption of epigenetic regulation and characteristic metabolic alterations (known as the Warburg-effect) are well-known hallmarks of cancer. In our study we investigated the expression levels of microRNAs and histone deacetylase enzymes via RT-qPCR in bone marrow specimens of adult patients suffering from hematological malignancies (total cohort n = 40), especially acute myeloid leukemia (n = 27). The levels of the three examined Warburg-effect related microRNAs (miR-378*, miR-23b, miR-26a) positively correlated with each other and the oncogenic miR-155 and miR-125b, while negatively with the level of the tumorsuppressor miR-124...

Matrix metalloproteinases-2 (MMP-2) and the tissue inhibitor of metalloproteinase-2 (TIMP-2), may presumably have an important role on the invasion and metastatic spread of malignancies attributed to an uncontrolled degradation of the extracellular matrix (ECM). A retrospective chart analysis was carried out to study the expression of MMP-2 and TIMP-2 on the archival samples of oral squamous cell carcinoma (OSCC) (n = 30) and normal mucosa (n = 10) by immunohistochemistry and compared with the clinicopathologic parameters of cases...

Recently, there are more and more evidences from studies have revealed the association between microRNA-9 (miR-9) expression and outcome in multiple cancers, but inconsistent results have also been reported. It is necessary to rationalize a meta analysis of all available data to clarify the prognostic role of miR-9. Eligible studies were selected through multiple search strategies and the quality was assessed by MOOSE. Data was extracted from studies according to the key statistics index. All analyses were performed using STATA software...

For the first time in the word, we investigated the association between five FSHR polymorphisms with the risk of cervical cancer among Tunisians. Study subjects comprised 112 Cervical Cancer (CC) patients and 164 control women. Genotyping of FSHR rs6166, rs1007541, rs11692782, rs2055571 and rs1394205 variants was done by realtime PCR, with defined clusters. The allelic distributions of the tested FSHR SNPs were comparable between CC patients and control women. In contrast, the heterozygous genotype of rs1007541 was associated with 1...

Thymoma and thymic carcinoma are thymic epithelial tumors (TETs). We performed a molecular profiling to investigate the pathogenesis of TETs and identify novel targets for therapy. We analyzed 37 thymomas (18 type A, 19 type B3) and 35 thymic carcinomas. The sequencing of 50 genes detected nonsynonymous mutations in 16 carcinomas affecting ALK, ATM, CDKN2A, ERBB4, FGFR3, KIT, NRAS and TP53. Only two B3 thymomas had a mutation in noncoding regions of the SMARCB1 and STK11 gene respectively. Three type A thymomas harbored a nonsynonymous HRAS mutation...

Benign and malignant tumours are known to express various factors inducing lymphangiogenesis. Despite their different biological behaviour, salivary pleomorphic adenomas (PA) and adenoid cystic carcinomas (SACC) show similar lymphatic network. Authors compare density of lymphatic network in these tumours. The retrospective study included 20 SACC and 20 PA from salivary tumours. Lymphatic vessel density (LVD) was identified using D2-40 antibody and counted. In SACC, intratumoral, respectively peritumoral, lymphatic vessels were identified in 100 %, respectively 93...

Breast cancer affects every 1 of 3000 pregnant women or in the first post-partum year is referred as Pregnancy Associated Breast Cancer (PABC) in mid 30s. Even-though rare disease, classified under hormone receptor negative status which metastasis quickly to other parts by extra cellular matrix degradation. Hence it is important to find an optimal treatment option for a PABC patient. Also additional care should be taken to choose the drug; in order to avoid fetal malformation and post-partum stage side-effects...

Aquaporins (AQP) are transmembrane proteins that provide channels for water and solutes, and some are involved in tumor progression and invasion. We evaluated the expression of AQP-1, AQP-3, and AQP-5 and their clinicopathological significance in prostate adenocarcinomas (PCA). Prostatectomy specimens (n = 99) were retrieved from the surgical pathology archives and clinicopathological data were obtained from the medical database at Kyungpook National University Hospital. Immunohistochemical staining for AQP-1, AQP-3, and AQP-5 was performed on tissue microarrays comprising paired malignant and benign prostatic tissues...

Frozen biopsies are frequently used for decision making during surgery. This study aimed to evaluate the efficacy of frozen biopsy for guiding decision making before laser excision of glottic premalignant lesions. One hundred patients with 119 laser excisions were included in this study and reviewed retrospectively. After frozen biopsy, type I or II cordectomy was performed and the frozen result and final pathology of the excisional specimen were compared. The positive predictive value of frozen biopsy when the diagnosis is benign or malignant was relatively high (80...

Benign testicular teratomas are always thought to be pediatric neoplasms and previously all the teratoid tumors in the adult testis regarded as malignant. Recently, three publications reported benign testicular teratomas in adulthood and the latest WHO classification refers them as "prepubertal type of teratomas" which rarely appear in adulthood. These neoplasms behave benign and seemingly analogous independently whether they appear in pre- or postpubertal patients. The aim of our study was to investigate the frequency of benign testicular teratomas both in children and adults...

IL-37 is a newly discovered cytokine belonging to IL-1 family consisting of 11 members, which have similar β-barrel structures and associate with Ig-like receptors. Extensive studies have been done with IL-37 since its discovery. These studies suggest that IL-37 does not only play a role in tumorigenesis, but also has anti-inflammatory properties in immune responses through the down regulation of pro-inflammatory molecules. We have previously reviewed the role of IL-37 in cancer. Here, we will focus on the role of IL-37 in non-cancerous Diseases...

Macrophage migration inhibitory factor (MIF) emerged in recent years as an important inflammation mediator, playing a prominent role in the pathogenesis of various types of malignant neoplasm. MIF is a glycoprotein that presents a wide spectrum of biological activities and exerts a complex interaction with various cellular signaling pathways, causing imbalance of homeostasis. Experimental and clinical studies show that high levels of MIF are found in almost all types of human cancers and are implicated in seemingly all stages of development of the tumors...

: BRAF gene mutations have been observed in 30-50 % of malignant melanoma patients. Recent development of therapeutic intervention using BRAF inhibitors requires an accurate and rapid detection system for BRAF mutations. In addition, the clinical characteristics of the melanoma associated with BRAF mutations in Japanese patients have not been investigated on a large scale evaluation. We recently established quenching probe system (QP) for detection of an activating BRAF mutation, V600E and evaluated 113 melanoma samples diagnosed in Saga University Hospital from 1982 to 2011...
