[Extremity soft tissue sarcoma: does surgical margin impact survival?].

Objective: To define the impact of surgical margins on local recurrence (LR), distant recurrence (DR) and overall survival (OS) in patients with soft tissue sarcomas of the extremities (eSTS).

Method: Patients treated for a primary eSTS from 2006 to 2010 were analyzed. Rates of local recurrence, distant recurrence, and overall survival were estimated using the Kaplan-Meier method.

Giant liver teratoma with gliosis peritonei treated by right extended hepatectomy: Overview and case report.

Germ cell tumors (GCTs) are considered as extragonadal if there is no evidence of a primary tumor in the testes or ovaries. GCTs can be classified as seminomas, non-seminomatous, mature teratomas, and immature teratomas based upon histology. Mature teratomas are generally found in prepuberal children.

[Morbimortalidad de la pancreatoduodenectomía en pacientes con cáncer de páncreas y tumores periampulares en el Hospital de Oncología del Centro Médico Nacional Siglo XXI de 2008 a 2013].

Introduction: Pancreatic tumors and periampullary tumors have a similar clinical presentation; pancreatoduodenectomy represents the only possibility of cure or of increasing survival; with an average mortality of 5-10% and a morbidity of 20-40%.

Objective: To determine the morbidity and mortality secondary to the pancreatoduodenectomy intervention in patients with pancreatic cancer or periampullary tumors in the Oncology Hospital of Centro Médico Nacional Siglo XXI (Mexico City) from 2008 to 2013.

Method: Historical, observational and descriptive cohort carried out in the department of sarcomas and tumors of the upper digestive tube of the Oncology Hospital of Centro Médico Nacional Siglo XXI, postoperative pancreatoduodenectomy from 2008 to 2013.

[Prognostic factors for survival in patients with resectable advanced gastric adenocarcinoma].

Background: Patients under 45 years with gastric cancer are associated with a poor prognosis. Recent studies report that the 5-year survival is better in younger patients after curative resection.

Objective: To determine if prognostic factors such as age under 45 years old, anaemia, weight loss, tumour differentiation, histological sub-type, depth of invasion, and lymph node involvement, reduce the survival of patients with resectable advanced gastric adenocarcinoma undergoing gastrectomy with limited and extended lymphadenectomy.

Factors associated with early peritoneal dialysis catheter replacement in Veracruz, Mexico.

Introduction: Catheter-related complications in patients on peritoneal dialysis lead to decreased effectiveness and discontinuation of the technique, conversion to haemodialysis, hospitalisation, and surgical interventions to replace the catheter.

Objectives: Determine risk factors for early catheter dysfunction that result in the need for replacement.

Methods: We analysed 235 catheters placed by open surgery using an infra-umbilical midline incision.
