PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks.

Abstract Background Malnutrition is a state linked to worse postoperative outcomes, and cancer patients are particularly vulnerable due to cachexia. We aimed to explore the effect of malnutrition on 30-day mortality following gastric and colorectal cancer surgery. Method GlobalSurg3 was multicentre international cohort study which collected data from consecutive patients undergoing emergency or elective surgery for gastric and colorectal cancer. Malnutrition was defined using the Global Leadership Initiative on Malnutrition (GLIM) criteria. Multilevel variable regression approaches determined the relationship between malnutrition and early postoperative outcomes. Results 6438 patients were included in the final analysis (1184 gastric cancer; 5254 colorectal cancer). Severe malnutrition was common across all income-strata, affecting 1 in 4 patients overall, with a higher burden in low and lower-middle income countries (64%). In patients undergoing elective surgery (n = 5709), severe malnutrition was independently associated with increased mortality (aOR = 1.62 (1.07-2.48, P = 0.024) after accounting for patient factors, disease stage and country effects. Conclusions Severe malnutrition represents a high global burden in cancer surgery, particularly within lower income settings. Malnutrition is an independent risk-factor for 30-day mortality following elective surgery for gastric and colorectal cancer, suggesting perioperative nutritional interventions may improve outcomes after cancer surgery.

Abstract Background Many authors have investigated the possible adverse effects among patients who underwent elective surgery on Friday when compared with patients operated earlier in the week. Nonetheless, the weekday effect is still a matter of debate. This study aimed at investigating the postoperative morbidity rates after lung cancer surgery and their relationship with the weekday the surgery took place. Materials and Methods We retrospectively reviewed the clinical records of patients who underwent elective thoracotomic lobectomies for lung cancer. Categorical data were analyzed using the chi-square test or Fisher's exact test. Association between predictors and binary outcomes while considering the weekday stratification was determined with Cochran–Mantel–Haenszel statistics. To characterize the typical Friday patient, a multiple logistic regression analysis was performed. Results A total of 817 patients (2015–2019) were identified. Complication rates divided by day of surgery were 164 (20.07%) for patients operated on Mondays, 182 (22.27%) on Tuesdays, 205 (25.09%) on Wednesdays, 172 (21.05%) on Thursdays, and 94 (11.51%) on Fridays. Crude morbidity rates by weekday were Monday 21.53%, Tuesday 20.51%, Wednesday 27.70%, Thursday 20.0%, and Friday 10.26%. No overall association between day of surgery and overall morbidity was found (ρ = 0.095). Median hospital length of stay was 5 days (range: 2–45 days), and there were no statistically significant differences between days. The Cochran–Mantel–Haenszel statistics showed no association between morbidity and the weekday. Conclusion In patients undergoing elective lobectomies for lung cancer, the weekday of surgery was not statistically significantly associated with an increase in the risk of postoperative morbidity.

Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population.

Abstract Background The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery is poorly understood. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality. The secondary outcome measure was pulmonary complications (pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation). Findings This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p < 0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p < 0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p < 0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p = 0·046), emergency versus elective surgery (1·67 [1·06–2·63], p = 0·026), and major versus minor surgery (1·52 [1·01–2·31], p = 0·047). Interpretation Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than normal practice, particularly in men aged 70 years and older.

Abstract Introduction Malnutrition is a key priority on the global health agenda, yet the impact of nutritional state on cancer surgery across income strata remains poorly described. This study aimed to determine the effect of malnutrition on early postoperative outcomes following elective surgery for colorectal or gastric cancer. Method Multicentre, international prospective cohort study of consecutive patients undergoing elective surgery for colorectal or gastric cancer. Malnutrition was defined using the Global Leadership Initiative on Malnutrition (GLIM) criteria. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression and three-way mediation analysis determined the relationship between country income group, nutritional status and early postoperative outcomes. Result This study included 5709 patients (4593 colorectal; 1116 gastric) from 381 hospitals in 75 countries. Severe malnutrition was present in one third of patients, with a disproportionate burden in upper middle (44%) and low/lower-middle income countries (64%). After adjustment for patient and hospital risk factors, severe malnutrition (aOR 1.62, 95% confidence interval 1.07 to 2.48; P = 0.024) was an independent predictor of 30-day mortality. However, major postoperative complications and surgical site infection rates were similar. Conclusion Severe malnutrition represents a high global burden in cancer surgery, particularly within low-income settings. Malnutrition is an independent risk-factor for 30-day mortality following elective surgery for colorectal or gastric cancer, suggesting perioperative nutritional interventions may improve early outcomes following cancer surgery. Take-home Message Severe malnutrition affects a large proportion of elective surgical oncology patients, with a significantly higher burden in low and middle income countries. Severe malnutrition is independently associated with increased 30-day mortality after cancer surgery.

Abstract Objective: The impact of baseline hypertension status on the BMI–mortality association is still unclear. We aimed to examine the moderation effect of hypertension on the BMI–mortality association using a rural Chinese cohort. Design: In this cohort study, we investigated the incident of mortality according to different BMI categories by hypertension status. Setting: Longitudinal population-based cohort Participants: 17,262 adults ≥18 years were recruited from July to August of 2013 and July to August of 2014 from a rural area in China. Results: During a median 6-year follow-up, we recorded 1109 deaths (610 with and 499 without hypertension). In adjusted models, as compared with BMI 22-24 kg/m2, with BMI ≤18, 18-20, 20-22, 24-26, 26-28, 28-30 and >30 kg/m2, the HRs (95% CI) for mortality in normotensive participants were 1.92 (1.23-3.00), 1.44 (1.01-2.05), 1.14 (0.82-1.58), 0.96 (0.70-1.31), 0.96 (0.65-1.43), 1.32 (0.81-2.14), and 1.32 (0.74-2.35) respectively, and in hypertensive participants were 1.85 (1.08-3.17), 1.67 (1.17-2.39), 1.29 (0.95-1.75), 1.20 (0.91-1.58), 1.10 (0.83-1.46), 1.10 (0.80-1.52), and 0.61 (0.40-0.94) respectively. The risk of mortality was lower in individuals with hypertension with overweight or obesity versus normal weight, especially in older hypertensives (≥60 years old). Sensitivity analyses gave consistent results for both normotensive and hypertensive participants. Conclusions: Low BMI was significantly associated with increased risk of all-cause mortality regardless of hypertension status in rural Chinese adults, but high BMI decreased the mortality risk among individuals with hypertension, especially in older hypertensives.
