Introduction: In Croatia, about 3,500 patients are diagnosed with a colorectal carcinoma annually. The National Program for Early Detection of Colon Cancer has been implemented in Croatia since 2007. program’s primary goal is todetect colon cancer at an early stage the disease, which should reduce incidence and mortality from cancer. Aim: To determine interest target group participating program...
Background and Purpose: Each year, about 50,000 new cases of cancer occur in Iran and the most common being the gastrointestinal (GI) tract (38%). Colorectal cancers account for the 3rd and 4th most prevalent cancers in Iranian men and women, respectively. Since genetic and environmental factors lead to differences in colorectal cancer occurrence in different geographic regions and races, we ...
introduction: photodynamic therapy is a noninvasive therapeutic method for tumors with a maximum depth of 5 mm. on the other hand, most photosensitizers are also susceptible to ultrasound waves (the basis of sonodynamic therapy). therefore, it is expected that a combination of the two therapeutic methods will increase effectiveness of photodynamic therapies for lower doses of sensitizer and cur...
Two cases of very rare intramedullary spinal cord metastasis from colon carcinoma and renal carcinoma were treated primarily by microsurgical excision. A 44-year-old female presented with colon carcinoma metastasis manifesting as complete neurological deficit. She had undergone colon resection 2 years previously for colon carcinoma. The tumor was excised by microsurgery with megadose steroid th...
The Hedgehog (Hh) signaling pathway not only plays important roles in embryogenesis and adult tissue homeostasis, but also in tumorigenesis. Aberrant Hh pathway activation has been reported in a variety of malignant tumors including colon carcinoma. Here, we sought to investigate the regulation of the Hh pathway transcription factor Gli1 by arsenic trioxide and phosphoinositide 3-kinase (PI3K) ...
the chloroform soluble fractions of ethanolic extracts of five inula belonging to the compositae family were evaluated for cytotoxic activity against five different cell lines including caco2 (human colon adenocarcinoma), mcf7 (human breast adenocarcinoma), hepg2 (human hepatocellular carcinoma), vero (green african monkey kidney) and wehi164 (balb c mouse fibrosarcoma). cytotoxicity was assess...
The chloroform soluble fractions of ethanolic extracts of five Inula belonging to the Compositae family were evaluated for cytotoxic activity against five different cell lines including CACO2 (human colon adenocarcinoma), MCF7 (human breast adenocarcinoma), HEPG2 (human hepatocellular carcinoma), VERO (green African monkey kidney) and WEHI164 (balb c mouse fibrosarcoma). Cytotoxic...
introduction: as a physical treatment, electrochemical therapy (echt) has provided an effective and useful approach for treating localized tumors. the chemical changes due to a direct electric current destroy the tumor. this study evaluates the effect of electrical dose and polarity on the efficacy of the treatment of a colon tumor model. materials and methods: in order to in...
Objective(s):Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells. Materials and Methods: Synthesis and characterization of GGS nanoshells were initially performed. CT26 cells were ...
Invasion into the matrix is one of hallmarks of malignant diseases and is the first step for tumor metastasis. Thus, analysis of the molecular mechanisms of invasion is essential to overcome tumor cell invasion. In the present study, we screened for colon carcinoma-specific genes using a cDNA microarray database of colon carcinoma tissues and normal colon tissues, and we found that fermitin fam...
