Summary
Background
80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality.
Methods
This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with
ClinicalTrials.gov
,
NCT03471494
.
Findings
Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications.
Interpretation
Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Purpose
Chronic pelvic pain syndrome (CPPS) is one of the most common outpatient urological diagnoses, and its incidence is increasing. Extracorporeal shockwave therapy (ESWT) has been suggested for relieving local perineal symptoms associated with chronic prostatitis/CPPS. Despite several treatment methods, no causal or standardized treatment is available for CPPS. This study aimed to investigate the efficacy and safety profile of ESWT for the treatment of chronic non-bacterial prostatitis.
Materials and methods
Studies were collected using four search engines (Pubmed, Cochrane, ScienceDirect, and EBSCOHost), on May 16, 2020; and assessed based on predetermined inclusion and exclusion criteria. Two reviewers performed study selection. Studies were then analyzed using Review Manager 5.3 for the meta-analysis.
Results
Seventy-four publications were initially retrieved, and three studies were considered for both qualitative and quantitative analyses. From these studies, we found that the use of ESWT was significantly associated with decreased pain domain (mean difference: -3.93; 95% confidence interval [CI] -5.13, -2.73; p<0.001), improved urinary score (mean difference: -1.79; 95% CI -2.38, -1.21; p<0.001), improved quality of life (mean difference: -1.71; 95% CI -2.12, -1.31; p<0.001), and improved National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) score (mean difference: -5.45; 95% CI -5.74, -5.16; p<0.001) after 12 weeks of treatment.
Conclusion
ESWT is efficacious and safe in reducing pain and improving urinary condition, NIH-CPSI score, and quality of life in patients with chronic non-bacterial prostatitis.
