Pleural and pulmonary dissemination patterns from gastric adenocarcinoma among patients with treated primary disease in Latin America.

Purpose: Latin America is one of the regions with the highest incidence of gastric cancer. Even though, there are not reports about the patterns of pleuro-pulmonary metastases in patients with gastric adenocarcinoma treated with curative intent and the prognosis according to each dissemination pattern.

Material And Methods: We conducted a retrospective analysis of patients with gastric adenocarcinoma treated with curative intent at the National Cancer Institute (INC) between 2010 and 2017.

Treatment Alternatives for Recurrent Esophagogastric Junction Adenocarcinoma: Case Report of an Ileocolonic Reconstruction and Literature Review.

Esophagogastric junction tumors are a challenging pathology for surgeons and the best treatment depends on an adequate initial localization and stadification. Approximately half of patients relapse after curative surgery during the first two years. Surgical resection could increase the survival of these patients, but the esophageal reconstruction is a surgical challenge for which there are multiple reconstruction techniques described with different organs.

[First experience of minimally invasive surgery in the upper digestive tract].

Background: Upper gastrointestinal cancer is responsible of important numbers deaths worldwide and is widely associated with lifestyle and genetic factors. Minimally invasive surgery treatment is still controversial wit difficult learning curves, longer operative times but clear advantages in bleeding, postoperative pain, return to activities and less complications associated with de incision.

Objective: Describe our first experience in minimally invasive surgery of the upper alimentary tract for cancer at the Instituto Nacional de Cancerología.

Metagenomic analysis of the gastric microbiota cultivable from a patient with gastritis concomitant with Barrett's esophagus.

Barrett's esophagus is a distal metaplasia characterized by the transformation of squamous mucosa into columnar mucosa. This esophageal phenotype is a product not only of the chronic reflux of gastric acids, but also by microorganisms that colonize the oral cavity and stomach. Two classes of microbiota can be identified in Barrett's esophagus; microbiota type I is associated with the normal esophagus and type II with an inflamed esophagus.

Relationship between quality of life and clinical status in patients with gastrointestinal cancer.

Background: previous studies with patients having cancer have shown that quality of life scores depend on the clinical stage of the disease (the more advanced the disease, the worst quality of life).

Methods: in a prospective study we studied 317 patients with gastric or colorectal cancer attending the Instituto Nacional de Cancerología between 2010 and 2011; the patients completed the EORTC QLQ-C30 before receiving treatment. This instrument measures quality of life in 15 domains.

[Helicobacter pylori genotypes in non atrophic gastritis are different of the found in peptic ulcer, premalignant lesions and gastric cancer in Colombia].

Background: Helicobacter pylori is recognized as an etiologic agent of several gastric diseases. Bacterial genotypes have been related to clinical outcome in several populations.

Aim: To compare cagA, vacA and iceA genotypes of Colombian isolates from patients with several gastrointestinal diseases, including gastric cancer.
