Aim: To correlate levels of tumor-infiltrating lymphocytes (TIL) evaluated using the International Immuno-Oncology Biomarker Working Group methodology, and both density immune cell clinicopathological features in different malignancies. Methods: 209 pathological samples from gastric cancer, cervical cancer (CC), non-small-lung cutaneous melanoma (CM) glioblastoma were tested for TIL hematoxylin eosin, CD3+, CD4+, CD8+, CD20+, CD68+ CD163+ cells by digital analysis. Results: higher invasive...
(HP) and Epstein Barr virus (EBV) infections induce chronic gastritis (CG) are accepted carcinogenics of gastric cancer (GC). Our objective for this study was to determine the prevalence these agents clinicopathological features GC CG associated with infection.
Objective: To evaluate the correlation between presence of H. pylori in paired samples tap water and gastric cancer (GC) lesion Lima city (Peru). Material methods: Gastric tissue tap-water were prospectively collected from 82 Cancer who lived Lima. HspA ureA genes evaluated by qPCR samples. Results: The median age patients with GC was 63 years, 52.4% men stage-II 36.6%. A home-living time> 10 years reported 84.1% patients. Boiling treatment indicated 85.4% cases. detected 69.5% tissues 12.2%...
Aim:Helicobacter pylori is usually detected based on hematoxylin-eosin (H-E) features, but, immunohistochemistry (IHC) and real-time PCR (RT-PCR) are more precise in chronic-gastritis. We evaluated the relevance of these tests Peruvian gastric cancer samples. Materials & methods: performed H-E, IHC staining RT-PCR 288 tumors. Slides were independently by three pathologists. Results:H. was 167/287 through 140/288 175/288 RT-PCR, positive-status associated (p < 0.001). H. detection H-E had a...
Objective: The aim of this study was to determine the relationship between Helicobacter pylori (H. pylori) infection in relatives and patients with gastric cancer (GC).Methods: H. evaluated by breath urease test 171 qPCR technique tissue 61 (n=45 for GC n=16 non-GC). Results: There were included 137 34 non-GC. median age a sample 39 years (10-86). Infection found 60.2% (n=103) relatives. no higher rates (62% vs 62.9%, p=0.33), (60% 60%, p=0.96), or metaplasia (58.8% 61.8%, p=0.71)....
