PURPOSE The aim of this study was to investigate the rate of monosomy 3 by CISH technique in Iranian patients with uveal melanoma (UM) and its correlation with clinical and histopathological features. METHOD Archival formalin fixed, paraffin-embedded material from 50 patients who had undergone enucleation for large uveal melanomas was obtained. Monosomy of chromosome 3 alteration by chromogen...

ALK is an established causative oncogenic driver in neuroblastoma, and is likely to emerge as a routine biomarker in neuroblastoma diagnostics. At present, the optimal strategy for clinical diagnostic evaluation of ALK protein, genomic and hotspot mutation status is not well-studied. We evaluated ALK immunohistochemical (IHC) protein expression using three different antibodies (ALK1, 5A4 and D5...

Carcinosarcoma of the anus is rare and has yet to be reportedly associated with the keratinocyte-specific Human Papilloma Virus (HPV). We describe a case of anal carcinosarcoma with HPV infection in both the epithelial and mesenchymal components of the tumor by immunohistochemistry, chromogenic in-situ hybridization (CISH) and further supported by electron microscopy (EM). Microscopic examinati...

The operative methods of total uterine mucosal ablation (TUMA) as well as new abdominal and vaginal hysterectomy techniques are described. Classic intrafascial serrated edged macro-morcellator (SEMM) hysterectomy (CISH) by pelviscopy or laparotomy and intrafascial vaginal hysterectomy (IVH) are techniques that allow the nerve and the blood supply of the pelvic floor to remain intact, mainly bec...

BACKGROUND Neuroblastoma (NB) is an aggressive tumor of childhood with a highly heterogeneous course. Identification of standard prognostic factors has several limitations. Hence, there is an increasing demand to identify new prognostic factors and tools that help in risk stratification of patients for proper treatment. OBJECTIVE To assess the prognostic and predictive impact of quantitative ...

The significant advance in the development of molecular-targeting drugs has made an evaluation of Her-2, EGFR, and cyclin D1 an important clinical issue in breast cancer patients. This study compared the Her-2, EGFR, and cyclin D1 status of primary tumors as well as their matching lymph node metastases using immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH) in 73 breast ca...

AIMS We aimed to develop a putative predictive biomarker score for future hepatocyte growth factor receptor (MET)-targeted therapy of gastric cancer (GC). METHODS AND RESULTS MET expression and MET amplification were analysed by immunohistochemistry (IHC) and chromogenic in-situ hybridization (CISH) in 470 GC patients. Immunostaining was documented with the HistoScore. The percentage area of ...

Correlative human studies suggest that the pleiotropic cytokine IL6 contributes to the development and/or progression of prostate cancer. However, the source of IL6 production in the prostate microenvironment in patients has yet to be determined. The cellular origin of IL6 in primary and metastatic prostate cancer was examined in formalin-fixed, paraffin-embedded tissues using a highly sensitiv...
