Impact of perioperative transfusions and sepsis on long-term oncologic outcomes after curative colon cancer resection. A retrospective analysis of a prospective database.

Objective: Intra-abdominal septic complications (IASC) affect short-term outcomes after surgery for colon cancer. Blood transfusions have been associated with worse short-term results. The role of IASC and blood transfusions on long-term oncologic results is still debated.

Prognostic Impact of pT Stage and Peritoneal Invasion in Locally Advanced Colon Cancer.

Background: TNM stage has been identified as an independent variable for local recurrence and survival after colon cancer resection. It is still unclear whether peritoneal invasion (pT4a) is a risk factor for adverse oncologic outcome or whether these patients have better results compared with contiguous organs infiltration (pT4b), independent from nodal status (pN).

Objective: The purpose of this study was to analyze whether peritoneal invasion is an independent risk factor for worse oncologic outcome after curative colon cancer resection.

Self-expanding metallic stent as a bridge to surgery in the treatment of left colon cancer obstruction: Cost-benefit analysis and oncologic results.

Introduction: The use of a self-expanding metallic stent as a bridge to surgery in acute malignant left colonic obstruction has been suggested as an alternative treatment to emergency surgery. The aim of the present study was to compare the morbi-mortality, cost-benefit and long-term oncological outcomes of both therapeutic options.

Methods: This is a prospective, comparative, controlled, non-randomized study (2005-2010) performed in a specialized unit.

Selective approach for upper rectal cancer treatment: total mesorectal excision and preoperative chemoradiation are seldom necessary.

Background: The implementation of preoperative chemoradiation combined with total mesorectal excision has reduced local recurrence rates in rectal cancer. However, the use of both types of treatment in upper rectal cancer is controversial.

Objective: The purpose of this work was to assess oncological results after radical resection of upper rectal cancers compared with sigmoid, middle, and lower rectal cancers and to determine risk factors for local recurrence in upper rectal cancer.
