ABSTRACT
Pancreatic cancer is a malignancy of great impact in developed countries and is having an increasing impact in Latin America. Incidence and mortality rates are similar for this cancer. This is an important reason to offer to the patients the best treatments available. During the Latin American Symposium of Gastroenterology Oncology (SLAGO) held in Viña del Mar, Chile, in April 2015, a multidisciplinary group of specialists in the field met to discuss about this disease. The main conclusions of this meeting, where practitioners from most of Latin American countries participated, are listed in this consensus that seek to serve as a guide for better decision making for patients with pancreatic cancer in Latin America.

Background: Extended gastrectomy allows a complete tumor excision in patients with advanced gastric cancer. Aim: To compare the surgical results of extended (ER) and non-extended gastrectomy (NER) among patients with gastric cancer, and determine factors associated with complications and mortality. Material and Methods: Review of medical records of patients with gastric cancer who underwent complete resection between 2002 and 2008 in an oncological hospital. Demographics, patient-related and therapeutic features were compared between groups, and independent factors were established with multivariate analysis. Results: Seventy four patients, (44 men, median age 62 years) underwent an ER and 103 patients, (56 men, median age 61 years) a NER. Specifically, ER included splenectomy alone in 27 patients, splenectomy associated with other procedure in 24, partial esophagectomy in 18, distal pancreatectomy in 13, hemicolectomy in 8, total esophagectomy in 7, partial hepatectomy in 4, and adrenalectomy in 1. Postoperative complications were observed in 19 patients treated with an ER (26 percent) and in 11 patients treated with a NER (11 percent), p < 0.05. Serious complications were higher in patients who underwent an ER compared with NER (6 patients (8 percent) vs. 4 (4 percent), respectively) p < 0.05. In the same way, mortality was higher in patients treated with ER when it was compared with NER (4 patients (5 percent) vs two (2 percent), respectively), p < 0.05. ER and serum albumin levels were independent factors associated to a higher risk of mortality and rate of complications. Conclusions: ER was associated with a higher rate of general and severe complications, and mortality.

Background: The long-term survival of adenocarcinoma of the esophago-gastric junction is poor and depends on the possibility of performing a complete surgical excision and the absence of lymph node involvement. Aim: To report surgical results and survival of patients with adenocarcinoma of the esophago-gastric junction. Material and Methods: Retrospective review of medical records of patients with adenocarcinoma of the esophago-gastric junction, subjected to a curative surgical procedure between 2000 and 2008. Deaths that occurred within 60 days of the operation were considered operative mortality. Tumor stage was determined using TNM and Siewert pathological classifications. Results: Thirty-nine patients aged 40 to 80years (27 men), were operated. According to Siewert classification, seven patients had type I, six type II and 26 type III tumors. Twenty-two patients were subjected to a total gastrectomy with partial excision of distal esophagus and mediastinal reconstruction, 10patients were subjected to a trans-hiatal esophagectomy and seven to a total esophagogastrectomy. According to postoperative staging, five patients were in stage I, 12 in stage II, nine in stage III and 13 in stage IV. Median, three and five year's survival figures were 21.4 months, 33 and 25 percent, respectively. Lymph node and perineural involvement was associated with a lower survival. Well differentiated and stage I tumors had a better survival. Multivariate analysis showed that the presence of a type III tumor, N3 lymph node involvement and vascular permeation were independent predictors' ofa lower survival. Conclusions: Among patients with adenocarcinoma of the esophago-gastric junction, type III tumors, lymph node involvement and vascular permeations are associated with a lower survival.

Esophageal melanomas correspond to 0.1 to 0.2 percent of esophageal tumors. We report two patients with the disease. The first patient is a 51 year-old woman pre-sentingwith dysphagia and weight loss. An upper gastrointestinal endoscopy showed a polypoid ulcerated lesion in the middle third of the esophagus. The pathological study ofthe biopsy disclosed a malignant melanoma. The patient was subjected to an esophagectomy with a satisfactory postoperative evolution. Four months later, liver metastases were detected and the patient died eleven months after the operation. The second patient is a 59 year-old mole that consulted by dysphagia. An endoscopy showed a pigmented esophageal lesion whose pathological diagnosis was a malignant melanoma. The patient was subjected to an esophagectomy and sixteen months after surgery there was no evidence of relapse.

Fibrolamellar hepatocellular carcinoma (FLC) is a rare histologic variant of hepatocellular carcinoma that appears most commonly in teenagers and young adults. The diagnosis is often made incidentally and surgical resection is the only curative treatment. Here we report two cases of incidental FLC involving a 19 year-old male, initially diagnosed with screening abdominal ultrasound, and a 14 year-old female that presented with abdominal pain. Diagnostic workup consisted of abdominal PET/CT and MRI Imaging studies and tissue diagnosis was confirmed with percutaneous liver biopsy. Both patients were treated with radical liver resection/tumor excision. However, tumor recurrence was observed in both during short-term follow-up. The male patient was treated successfully with surgical treatment however the female patient succumbed top regression of disease.
