RESUMEN
PURPOSE: Brain metastasis (BM) in colorectal cancer patients is rare and is associated with dismal outcomes. Our study aims to evaluate the incidence and predictors of BM in patients with colorectal cancer. METHODS: We performed a retrospective analysis (2010-2017) of patients with a primary diagnosis of colorectal cancer (CRC). Patients were stratified into two groups (BM vs. No-BM). Outcome measures were the incidence and predictors of BM. Multivariate logistic regression analysis was performed. RESULTS: A total of 230,806 patients were analyzed. A total of 0.30% (n = 691) of the patients were found to have BM. On multivariate logistics regression, bone (OR: 5.39 [3.36-8.65], p < 0.001), lung (OR: 3.75 [2.67-5.28], < 0.001), and distant node metastasis (OR: 32.75 [20.47-52.41], p < 0.001) were independent predictors of BM. CONCLUSION: Our study supports the low incidence of brain metastasis in patients with colorectal cancer. A unique set of characteristics is identified to confer an increased risk of brain metastases.

BACKGROUND: Preoperative neoadjuvant chemotherapy (NAC) for colon cancer in advanced stages is associated with improved outcomes and tumor regression. The aim of our study was to identify outcomes in patients with colon cancer who received preoperative NAC. METHODS: A 4-year analysis of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) was performed. We included patients with locally advanced colon cancer (non-metastatic T3, T4 with or without nodal involvement) who underwent colon cancer resection. Patients were stratified into two groups (NAC and No-NAC). Our outcome measures were anastomotic leaks, hospital length of stay (LOS), 30-day complications, 30-day mortality, and 30-day readmissions. We performed a multi-variable logistic regression analysis. RESULTS: We analyzed 90,055 patients of which 7694 (NAC: 7.8 % (n = 599) and No-NAC: 92.2% (n = 7095)) met the inclusion criteria and included in the analysis. Mean age was 67 ± 13 years, 51% were males, and 72% were whites. Patients in the NAC group were more likely to be younger (60 ± 12 years vs. 68 ± 13 years, p < 0.01) and males (62% vs. 50%, p < 0.01) compared to No-NAC. On regression analysis, preoperative NAC was independently associated with higher odds of anastomotic leak (OR 1.35 [1.05-1.97], p = 0.03) and 30-day readmission (OR 1.54 [1.24-2.05], p < 0.01) in reference to No-NAC. However, no association was found between NAC and 30-day complications and 30-day mortality. CONCLUSIONS: Preoperative NAC might be associated with adverse outcomes of anastomotic leaks and 30-day readmissions, however does not appear to impact 30-day complications nor 30-day mortality.

Percutaneous coronary intervention with stent implantation is an integral aspect of minimally interventional cardiac procedures. The technology and techniques behind stent design and implantation have evolved rapidly over several decades. However, continued discourse remains around optimal peri- and post-interventional management with dual antiplatelet therapy to minimise both major cardiovascular or cerebrovascular events and iatrogenic bleeding risk. Standard guidelines around dual antiplatelet therapy historically recommended long-term dual antiplatelet therapy for 12 months (with consideration for >12 months in certain patients); however, emerging data and generational improvements in the safety of drug-eluting stents have ushered in a new era of short-term therapy to reduce the incidence of major bleeding events. This case review will provide an overview of the current state of guidelines around duration of dual antiplatelet therapy and examine recent updates and continued gaps in existing research.
