COVID‐19 infection and its consequences among surgical oncology patients: A systematic analysis, meta‐analysis and meta‐regression

Abstract

We conducted this meta‐analysis to address the outcomes in cancer patients after oncologic surgery during COVID‐19 pandemic. The primary endpoint was the COVID‐19–related mortality rate. Higher body mass index was significantly and negatively associated with higher all‐cause mortality and in‐hospital COVID‐19 infection rates. Male sex, preoperative respiratory disease, and smoking history were positively and significantly associated with increased all‐cause mortality rates. Furthermore, male sex was positively and significantly associated with the COVID‐19 infection rate.

Eligibility for elective surgery in patients recovering from mild COVID‐19: A propensity‐matched analysis

“…6 A meta-analysis demonstrated that male sex, smoking history, and preoperative respiratory disease were positively associated with increased mortality in patients who underwent cancer surgery during the COVID-19 pandemic. 19 This study used propensity score Note: The data are expressed as number (%). a Compared with SARS-CoV-2 negative group, χ 2 test, p < 0.05 significant.…”

“…An ASA Physical Status classification III–V was the only independent predictor of pulmonary complications 30 days after surgery 6 . A meta‐analysis demonstrated that male sex, smoking history, and preoperative respiratory disease were positively associated with increased mortality in patients who underwent cancer surgery during the COVID‐19 pandemic 19 . This study used propensity score matching to reduce the effects of confounding variables.…”
