Alarming endoscopic data in young and older asymptomatic people: Results of an open access, unlimited age colonoscopic screening for colorectal cancer.

There is a lack of a national organized screening program for colorectal cancer in Greece, and asymptomatic detection is usually the result of individual decisions. The collection of epidemiologic endoscopic data from a population of interest would therefore provide valuable information for future treatment guidance, especially during periods of economic austerity. The current cross-sectional study included 380 asymptomatic, average risk individuals undergoing screening colonoscopy for the first time, during the period of one year in a tertiary public hospital in Athens.

PI3K/AKT pathway genetic alterations and dysregulation of expression in bladder cancer.

Purpose: To examine the involvement of specific components of the PI3K/AKT pathway in urinary bladder cancer development.

Methods: Samples from 65 tumors and 13 normal bladder tissues were collected. Genomic DNA isolation from snap-frozen and paraffin-embedded laser-microdissected tissues was followed by Sanger sequencing, whereas total RNA was purified for use in RT-PCR analyses.

Glutathione-S-transferase-pi (GST-pi) expression in renal cell carcinoma.

Multidrug resistance correlates with unfavourable treatment outcomes in numerous cancers including renal cell carcinoma. The expression and clinical relevance of Glutathione-S-transferase-pi (GST-pi), a multidrug resistance factor, in kidney tumors remain controversial. We analyzed the expression of GST-pi in 60 formalin-fixed, paraffin-embedded renal cell carcinoma samples by immunohistochemistry and compared them with matched normal regions of the kidney.

Somatic mutations of adenomatous polyposis coli gene and nuclear b-catenin accumulation have prognostic significance in invasive urothelial carcinomas: evidence for Wnt pathway implication.

Wnt pathway signaling is crucial in many cancers and data indicate crosstalk with other key cancer pathways, however in urothelial carcinogenesis it has not been extensively studied. We searched for mutations in adenomatous polyposis coli (APC), a key regulator of the pathway, and studied b-catenin expression and interactions with the expression of other markers of apoptosis, angiogenesis, and proliferation in patients with invasive urothelial cancer. The mutation cluster region of APC was directly sequenced in 70 patients with muscle invasive disease who were treated with surgery and adjuvant chemotherapy.

Primary paratesticular adult ganglioneuroma.

Ganglioneuroma is a rare benign tumor, usually seen in children and young adults, arising in the central nervous system. Most of the noncranial ganglioneuromas are located in the posterior mediastinum and the retroperitoneum. We report the first case of a primary, adult paratesticular ganglioneuroma that presented as a paratesticular mass.
