Does Lymph Node Count Influence Survival in Surgically Resected Non-Small Cell Lung Cancer?
For NSCLC, the NLNS influenced both overall survival and cancer-specific survival, but the influence is dependent on stage. Surgeons should perform mediastinal lymphadenectomy to maximize patient survival, but the optimal NLNS remains unclear.
The data show that the grade of gastritis is an important risk factor for duodenal ulcer recurrence. Cure of H. pylori infection is associated with healing of chronic H. pylori-associated gastritis. These data lend considerable support to the hypothesis that H. pylori gastritis is the most important factor among those leading to duodenal ulcer disease.
