BRAZILIAN GASTRIC CANCER ASSOCIATION GUIDELINES (PART 1): AN UPDATE ON DIAGNOSIS, STAGING, ENDOSCOPIC TREATMENT AND FOLLOW-UP.

Background: The II Brazilian Consensus on Gastric Cancer by the Brazilian Gastric Cancer Association (ABCG) was recently published. On this occasion, several experts in gastric cancer expressed their opinion before the statements presented.

Aim: To present the ABCG Guidelines (part 1) regarding the diagnosis, staging, endoscopic treatment and follow-up of gastric cancer patients.

II BRAZILIAN CONSENSUS ON GASTRIC CANCER BY THE BRAZILIAN GASTRIC CANCER ASSOCIATION.

Background: Since the publication of the first Brazilian Consensus on Gastric Cancer (GC) in 2012 carried out by the Brazilian Gastric Cancer Association, new concepts on diagnosis, staging, treatment and follow-up have been incorporated.

Aim: This new consensus is to promote an update to professionals working in the fight against GC and to provide guidelines for the management of patients with this condition.

Methods: Fifty-nine experts answered 67 statements regarding the diagnosis, staging, treatment and prognosis of GC with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree A consensus was adopted when at least 80% of the sum of the answers "fully agree" and "partially agree" was reached.

Gastric partitioning for the treatment of malignant gastric outlet obstruction.

Background: Gastric outlet obstruction (GOO) is one of the main complications in stage IV gastric cancer patients. This condition is usually managed by gastrojejunostomy (GJ). However, gastric partitioning (GP) has been described as an alternative to overcoming possible drawbacks of GJ, such as delayed gastric emptying and tumor bleeding.

MINIMALLY INVASIVE SURGERY FOR GASTRIC CANCER: TIME TO CHANGE THE PARADIGM.

Introduction: Minimally invasive surgery widely used to treat benign disorders of the digestive system, has become the focus of intense study in recent years in the field of surgical oncology. Since then, the experience with this kind of approach has grown, aiming to provide the same oncological outcomes and survival to conventional surgery. Regarding gastric cancer, surgery is still considered the only curative treatment, considering the extent of resection and lymphadenectomy performed.

Brazilian consensus in gastric cancer: guidelines for gastric cancer in Brazil.

Background: In Brazil, gastric cancer is the fourth most common malignancy among men and sixth among women. The cause is multivariate and the risks are well known. It has prognosis and treatment defined by the location and staging of the tumor and number of lymph nodes resected and involved.

Results of D2 gastrectomy for gastric cancer: lymph node chain dissection or multiple node resection?

Background: Eastern literature is remarkable for presenting survival rates for surgical treatment of gastric adenocarcinoma superior to those presented in western countries.

Aim: To analyze the long-term result after D2 gastrectomy for gastric cancer.

Methods: Two hundred seventy four underwent gastrectomy with D2 lymph node dissection as exclusive treatment.

Does the intraoperative peritoneal lavage cytology add prognostic information in patients with potentially curative gastric resection?

Peritoneal recurrence is the foremost pattern of failure after potentially curative resection for gastric cancer. Our aim was to evaluate the prognostic value of intraperitoneal free cancer cells (IFCCs) in peritoneal lavage of patients who underwent potentially curative resection for gastric carcinoma. Two hundred twenty patients with gastric cancer stage I, II, or III were prospectively evaluated with peritoneal lavage and cytologic examination.

Inflammatory bowel diseases: principles of nutritional therapy.

Inflammatory Bowel Diseases - ulcerative colitis and Crohn's disease- are chronic gastrointestinal inflammatory diseases of unknown etiology. Decreased oral intake, malabsorption, accelerated nutrient losses, increased requirements, and drug-nutrient interactions cause nutritional and functional deficiencies that require proper correction by nutritional therapy. The goals of the different forms of nutritional therapy are to correct nutritional disturbances and to modulate inflammatory response, thus influencing disease activity.
