ABSTRACT
Background and Objectives: Guidelines recommend deferral of elective surgery after COVID-19. Delays in cancer surgeries may affect outcomes. We examined perioperative outcomes of elective cancer surgery in COVID-19 survivors. The primary objective was 30-day all-cause postoperative mortality. The secondary objectives were 30-day morbidity, and its association with COVID-19 severity, and duration between COVID-19 and surgery. Methods: We collected data on age, gender, comorbidities, COVID-19 severity, preoperative investigations, surgery performed, and intra and postoperative outcomes in COVID-19 survivors who underwent elective cancer surgery at a tertiary-referral cancer center. Results: Three hundred and forty-eight COVID-19 survivors presented for elective cancer surgery. Of these, 332/348 (95%) patients had mild COVID-19 and 311 (89%) patients underwent surgery. Among patients with repeat investigations, computerized tomography scan of the thorax showed the maximum new abnormalities (30/157, 19%). The 30-day all-cause mortality was 0.03% (1/311) and 30-day morbidity was 17% (54/311). On multivariable analysis, moderate versus mild COVID-19 (odds ratio [OR]: 1.95;95% confidence interval [CI]: 0.52–7.30;p = 0.32) and surgery within 7 weeks of COVID-19 (OR: 0.61;95% CI: 0.33–1.11;p = 0.10) were not associated with postoperative morbidity. Conclusions: In patients who recover from mild to moderate COVID-19, elective cancer surgery can proceed safely even within 7 weeks. Additional preoperative tests may not be indicated in these patients. © 2022 Wiley Periodicals LLC.
