Total Axillary Lymphadenectomy in the Management of Breast Cancer
• The optimal extent of axillary dissection in patients with breast cancer remains unclear. We report 278 total axillary lymphadenectomies (levels I, II, and III and Rotter's [inter-pectoral] nodes) that were performed in 264 closely followed up private patients. There have been no axillary recurrences to date (mean follow-up, 50 months). If only level I and II nodes had been removed, the false-negative staging error would have been only 2.6%. However, 29 (31.5%) of 92 pathological node-positive axillae contained apical and/or Rotter's metastases. The incidence of complications was comparable with that reported for partial lymphadenectomy. Arm lymphedema developed in 6% of nonirradiated patients; postoperative radiotherapy and gross nodal disease were significant risk factors for lymphedema. Total axillary lymphadenectomy largely prevents axillary recurrence, eliminates the small staging error inherent in partial lymphadenectomy, and has acceptable morbidity, provided radiotherapy to the regional nodal areas is avoided.(Arch Surg. 1991;126:1336-1342
SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study
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.The aim of this study was to inform vaccination prioritization by modelling the impact of vaccination on elective inpatient surgery. The study found that patients aged at least 70 years needing elective surgery should be prioritized alongside other high-risk groups during early vaccination programmes. Once vaccines are rolled out to younger populations, prioritizing surgical patients is advantageous
