Determination of Effective Factors on Survival of GI Cancers: Results of Five Years Follow up in Iranian Population.

BACKGROUND: The gastrointestinal cancers are among the most common cause of cancer-related death and their long term survival is very low. This study was aimed to determine the effective factors on survival of gastrointestinal cancers among Iranian population during 5 years of follow up. METHODS: In total, 157 patients diagnosed as gastrointestinal cancers from 2007 to 2009 in the only center of endoscopy in Alvand city, northwest of Qazvin province were included and followed for five years. The univariate and multivariate analysis were done using Kaplan-Meier method and the Cox model respectively. RESULTS: Observations of 146 patients were analyzed (99 (67.8%) males and 47 (32.2%) females). The mean age was 64.73± 13.23 and 58.28±13.91 for females and males respectively. The one and three years survival rates for esophageal cancer were 28% and 9% and the one, three and five years survival rates for gastric cancer were 31%, 26% and 14% and for colorectal cancer were 96%, 86% and 75% respectively. In the univariate analysis, variables of age, educational level, ethnicity, smoking, type of cancer, stage of disease and type of treatment had significant effects on survival. In the multivariate analysis, the type of cancer and type of treatment affected the survival of patients as effective factors (p<005). CONCLUSION: Patients with esophageal cancer and those who underwent RT &/or CT are exposed to higher risk of death. Combination therapies (Surgery and adjuvant or neoadjuvant therapy) were related to be her survival. Early diagnosis and use of extended cancer screening programs seem necessary to improve survival.

Low dose furazolidone for eradication of H- pylori instead of clarithromycin: a clinical trial.

BACKGROUND: Helicobacter pylori infection is a common chronic human bacterial infection. Triple- therapy regimen containing a proton pump inhibitor, clarithromycin, and either amoxicillin or metronidazole is commonly used as first-line treatment for its eradication. However, it may not provide the acceptable eradication rate. The present study was designed to evaluated efficacy of low dose furazolidone with amoxicillin and omeprazole for eradication of H- pylori. MATERIALS & METHODS: One hundred twenty patients with non- ulcer dyspepsia or peptic ulcer confirmed by upper GI endoscopy, plus H- pylori infection confirmed by rapid urease test were included in the study. They were randomly divided into two groups, and then received clarithromycin, amoxicillin, and omeprazole, or furazolidone (100 mg PO bid), amoxicillin, and omeprazole. They were evaluated using urea breath test at the end of the study. FINDINGS: The eradication rates were 57.6% and 78.8% in clarithromycin and furazolidone groups, respectively. Their difference was statistically significant (P value 0.013). No side effect was seen in the furazolidone group. CONCLUSION: Low dose furazolidone rather than clarithromycin can be used as low- cost and effective drug for eradication of H- pylori, in combination with amoxicillin and omeprazole.
