AIMS AND BACKGROUND Colorectal cancer is one of the commonest cancers. Chemoradiotherapy gives better results than radiotherapy or chemotherapy in colorectal cancer. To enhance radiosensitivity of tumor cells for chemoradiotherapy, targeted therapy drugs that act as radiosensitizers can be used. In the present study, we provide a scientific rationale for the clinical application of sorafenib as...
The serine/threonine protein kinase B/Akt plays a central role in the coordination of multiple signal transduction processes involved in transcriptional regulation, cell survival, and apoptosis. Activation of Akt kinase is a prognostic factor in several types of cancers; however, its role in gastrointestinal cancers is not fully understood. Caspase-9 is an Akt substrate that belongs to the casp...
BACKGROUND AND AIMS Helicobacter pylori infection may be associated with an increased risk of colorectal carcinoma. However, as most studies on this subject were relatively small in size and differed at least partially in their designs, their results remain controversial. In this study, we aimed to carry out a meta-analysis to evaluate the potential association of H. pylori infection with color...
Oxidative stress is one of several factors which contribute to the development of colorectal carcinogenesis. The aim of the study was an assessment of the activity of antioxidant enzymes in tumour and corresponding normal distal mucosa in a group of patients with colorectal adenocarcinoma. Samples of tumour and corresponding normal mucosa were obtained during a resection of colorectal cancer fr...
Background: Colorectal cancer (CRC) is one of the most common neoplasms with high mortality at advanced stages worldwide. Thus diagnosis of CRC at an early stage with sensitive molecular methods is a high priority. The aim of this study was to evaluate P16ink4a subcellular expression patterns in colorectal adenocarcinoma, adenoma and non-neoplastic tissue samples. Methods: A total of 137 colore...
INTRODUCTION Orotate phosphoribosyl transferase (OPRT), dihydropyrimidine dehydrogenase (DPD), and thymidylate synthase (TS) are initial key enzymes in the 5-fluorouracil (5-FU) metabolic pathway. The expression levels and activities of these three enzymes play important roles in the response of cancer patients to 5-FU-based chemotherapy. PURPOSE The purpose of this study was to investigate t...
Spermatic cord is a rare metastatic site of colorectal cancer. We herein report a case of spermatic cord metastasis of a previous undiagnosed multifocal colon adenocarcinoma, which was clinically presented as a strangulated groin hernia.
