RESUMO

BACKGROUND: While the current literature suggests an association with frailty and clinical outcomes in patients undergoing surgery for colorectal cancer (CRC), the basis of this relationship is unclear. AIM: Examine the relationship between frailty, malnutrition, body composition, systemic inflammation and short-term clinical outcomes in patients undergoing surgery for colorectal cancer. METHODS: Consecutive patients who underwent potentially curative resection for colorectal cancer, between April 2008 and April 2018, were identified from a prospectively maintained database. Frailty was defined using the modified five-item frailty index (mFI-5). Body composition measures included CT-derived skeletal muscle index (SMI) and density (SMD). Systemic inflammatory status was determined using Systemic Inflammatory Grade (SIG). Outcomes of interest were the incidence of post-operative complications and thirty-day mortality. Associations between categorical variables were examined using χ2 test and binary logistics regression analysis. RESULTS: 1002 patients met the inclusion criteria. 28% (n = 221) scored 2 or more on the mFI-5. 39% (n = 388) of patients had a post-operative complication (Clavien-Dindo I-IV) and 1% (n = 11) died within thirty days of surgery. On univariate analysis, mFI-5 frailty score, was significantly associated with advanced age (p < 0.001), colonic tumours (p < 0.001), reduced use of neo-adjuvant chemotherapy (p < 0.05), higher BMI (p < 0.05), low SMD (p < 0.001), elevated NLR (p < 0.05), elevated mGPS (p < 0.05), elevated SIG (p < 0.05), incidence of post-operative complications (p < 0.001) and thirty-day mortality (p < 0.05). On multivariate analysis, male sex (p < 0.05), elevated SIG (p < 0.05) and mFI-5 score (p < 0.01) remained significantly associated with the incidence of post-operative complications. mFI-5 frailty was found to remain significantly associated with the incidence post-operative complications in patients who were SIG 0 (p < 0.05). CONCLUSION: mFI-5 frailty score was found to be significantly associated with age, systemic inflammation and post-operative outcomes in patients undergoing potentially curative resections for CRC. Incorporation of an assessment of systemic inflammatory status in future frailty screening tools may improve their prognostic value.

RESUMO

High vagal nerve activity, reliability measured by HRV, is considered protective in cancer, reducing oxidative stress, inflammation and opposing sympathetic nerve activity. The present monocentric study examines the relationship between HRV, TNM stage, co-morbidity, systemic inflammation and survival in patients who underwent potentially curative resections for colorectal cancer (CRC). Time-domain HRV measures, Standard Deviation of NN-intervals (SDNN) and Root Mean Square of Successive Differences (RMSSD), were examined as categorical (median) and continuous variables. Systemic inflammation was determined using systemic inflammatory grade (SIG) and co-morbidity using ASA. The primary end point was overall survival (OS) and was analysed using Cox regression. There were 439 patients included in the study and the median follow-up was 78 months. Forty-nine percent (n = 217) and 48% (n = 213) of patients were categorised as having low SDNN (< 24 ms) and RMSSD (< 29.8 ms), respectively. On univariate analysis, SDNN was not significantly associated with TNM stage (p = 0.830), ASA (p = 0.598) or SIG (p = 0.898). RMSSD was not significantly associated with TNM stage (p = 0.267), ASA (p = 0.294) or SIG (p = 0.951). Neither SDNN or RMSSD, categorical or continuous, were significantly associated with OS. In conclusion, neither SDNN or RMSSD were associated with TNM stage, ASA, SIG or survival in patients undergoing potentially curative surgery for CRC.

RESUMO

BACKGROUND: Major hemorrhage is a significant cause of mortality and morbidity around the world. There is currently no consensus on the best empirical transfusion strategy. The current National Institute for Clinical Excellence (NICE) guidelines suggest a ratio of 1:1 of red blood cells and plasma. The aim of this study is to compare this to alternative strategies identified through review of the available literature with the objective of identifying the best protocol for mortality outcomes and complication rates. METHODS: A systematic review of the literature was conducted using four databases. Inclusion and exclusion criteria were applied to produce a suitable list of randomized control trials for review. Critical appraisal of each article was then performed, using a Scottish Intercollegiate Guidelines Network-approved checklist, in duplicate and was subject to further independent scrutiny when required. RESULTS: Evidence suggests that early administration of cryoprecipitate within the standard practiced major hemorrhage protocol is associated with a lower risk of mortality. Other strategies suggested a negative impact. Complications including incidence of thromboembolic events, multiple organ failure and sepsis as well as length of stay in hospital following activation of the different protocols and overall transfusion requirements were assessed. No clear optimal protocol was identified from our analysis. CONCLUSION: This project demonstrates that there is no significant clarity regarding morbidity and mortality. As a preliminary recommendation, cryoprecipitate supplementation suggests more favorable mortality over the current protocol. Due to the limited sample populations, we recommend the inclusion of retrospective/prospective cohort studies to bolster the statistical power of any future reviews until randomized control trials of sufficient power are available. LEVEL OF EVIDENCE: Systematic review, Level III.
