Prognostic impact of log odds of positive lymph nodes (LODDS) in the stratification of patients with rectal cancer.

Introduction: The use of the N category of the TNM staging system, lymph node ratio (LNR) and log odds of positive lymph nodes (LODDS) in predicting overall survival (OS) and disease-free survival (DFS) in patients with rectal cancer is still controversial.

Material And Methods: A retrospective study of 445 patients with rectal cancer who underwent surgery between 2008 and 2017 in the University Complex Hospital of Vigo was performed. Patients were stratified according to number of lymph nodes examined (NLNE), N staging, LNR and LODDS.

Under-reporting by surgical pathologists in tissue removed during revision surgery for metal-on-metal arthroplasties.

Although adverse local tissue reactions (ALTR) have been reported for metal-on-metal implants (MoM) requiring early revision surgery, no study has looked at the accuracy of surgical pathologists in diagnosing ALTR. This study aims to investigate the accuracy of reporting adverse local tissue reactions in tissue samples following revision surgery from metal-on-metal implants. The authors reviewed histology glass slides as well as the original pathology reports of tissue processed in revision arthroplasties in 23 cases.

"Long-term oncologic outcomes and risk factors for distant recurrence after pathologic complete response following neoadjuvant treatment for locally advanced rectal cancer. A nationwide, multicentre study".

Background: Pathologic complete response (pCR) after multimodal treatment for locally advanced rectal cancer (LARC) is used as surrogate marker of success as it is assumed to correlate with improved oncologic outcome. However, long-term oncologic data are scarce.

Methods: This retrospective, multicentre study updated the oncologic follow-up of prospectively collected data from the Spanish Rectal Cancer Project database.

Stent as bridge to surgery decreases postoperative complications without worsening oncological outcomes: retrospective unicentric cohort study and stent placement protocol.

Background: Even if the use of stent as bridge to surgery (BTS) for obstructive colon cancer was described long ago, there is still much controversy on their use. Patient recovery before surgery and colonic desobstruction are just some of the reasons to defend this management that can be found in several available articles.

Methods: This is a single-center, retrospective cohort study, including patients with obstructive colon cancer treated between 2010 and 2020.
