ABSTRACT Background: Esophageal cancer neoadjuvant therapy followed by surgery increases the likelihood of treatment success. Aim: To evaluate variables that can influence the number of retrieved lymph nodes, the number of retrieved metastatic lymph nodes and lymphnodal recurrence in esophagectomy afte...
ABSTRACT Background: The treatment of advanced gastric cancer with curative intent is essentially surgical and chemoradiotherapy is indicated as neo or adjuvant to control the disease and prolong survival. Aim: To assess the survival of patients undergoing subtotal or total gastrectomy with D2 lymphade...
ABSTRACT Background: Since 1990 it was proposed that distal and proximal location of colon cancer might follow different biological, epidemiology, pathology and prognosis, probably due to embryologic different development of the two segments of the colon, which may represent two separate disease entitie...
ABSTRACT Introduction: Pancreatic neuroendocrine tumors (pNET) correspond to about 3% of all tumors in pancreas and could be presented as a difficult diagnosis and management. Objective: To review the diagnosis and treatment of the pNET available in scientific literature. Method: A bibliographic su...
ABSTRACT Introduction: Gastric gastrointestinal tumors (GIST) are a rare and usually asymptomatic neoplasm that can present as abdominal mass in more advanced scenarios. Since surgical resection is the main aspect of the treatment, locally advanced tumors require multivisceral resection and, therefore, ...
ABSTRACT Background: Traditionally, total omentectomy is performed along with gastric resection and extended lymphadenectomy in gastric cancer (GC) surgery. However, solid evidences regarding its oncologic benefit is still scarce. Aim: To evaluate the incidence of metastatic omental lymph nodes (LN) ...
ABSTRACT Background: Metastasis is common in the diagnosis of pancreatic cancer, and the presence of epithelial-mesenchymal transition markers in circulating tumor cells may suggest worse prognosis. Aim: To correlate the number of circulating tumor cells (CTCs) in the peripheral blood of patients with...

ABSTRACT Background: The identification of prognostic factors of gastric cancer (GC) has allowed to predict the evolution of patients. Aim: Assess the reliability of the lymphoparietal index in the prediction of long-term survival in GC treated with curative intent. Method: Prospective study of the ...

ABSTRACT Background: Laparoscopic gastrectomy has numerous perioperative advantages, but the long-term survival of patients after this procedure has been less studied. Aim: To compare survival, oncologic and perioperative outcomes between completely laparoscopic vs. open gastrectomy for early gastric c...

ABSTRACT Background : It is believed that the Wnt pathway is one of the most important signaling involved in gastric carcinogenesis. Aim : To analyze the protein expression of canonical and non-canonical Wnt pathways in gastric carcinoma. Method : The immunohistochemistry was performed in 72 specimen...
