新型冠状病毒病2019（COVID-19）的传播对日常医疗产生了极大的破坏。我们调查了COVID-19大流行对我院骨骼和软组织肿瘤治疗的影响。我们在大阪市立大学医院比较研究了两组患者的临床数据，分别为COVID-19感染率增加的时期（2020年2月至12月，C组）和前一年相同时期（2019年2月至12月，NC组）。这些数据包括患者的年龄、性别、肿瘤类型、肿瘤数量、住院和门诊手术例数、手术时间、植入物使用情况、住院天数、住院费用、接受抗癌药物住院患者数量以及这两组患者的术后并发症。住院期间切除恶性骨骼和软组织肿瘤的病例数在 C 组中明显高于 NC 组（P = 0.01）。C组和NC组在手术时间、植入物使用以及术后并发症方面没有显著差异，但在住院天数和住院费用方面存在显著差异（P<0.001）。COVID-19大流行已被世界各地认为在各个领域产生不良影响。它对骨骼和软组织肿瘤治疗领域的住院费用和住院天数产生了负面影响。版权所有：© 2023 Ban等。本文是根据创作共用许可证发布的开放获取文章，其允许在任何媒介上无限制使用、分发和复制，前提是原始作者和来源被著名。

The spread of coronavirus disease 2019 (COVID-19) has caused a great deal of damage to daily medical care. We investigated the impact of the COVID-19 pandemic on bone and soft tissue tumor treatment at our hospital.We conducted a retrospective comparative study of two groups of patients at Osaka City University Hospital during the period of increasing COVID-19 infections (February-December 2020, group C) and the same period the previous year (February- December 2019, group NC). Clinical data, including patient's age, gender, type of tumor, neoplasms, number of surgical cases for inpatients and outpatients, operation time, use of implants, length of hospital stay, inpatient hospital costs, number of inpatients receiving anticancer drugs, and postoperative complications in these two groups were retrospectively evaluated.The number of cases of malignant bone and soft tissue tumors that were resected during hospitalization was predominantly higher in group C than in group NC (P = 0.01). There were no significant differences in operation time, use of implants, and postoperative complications between group C and group NC, but there were significant differences in the length of hospital stay and hospital costs (P<0.001).The COVID-19 pandemic has been recognized throughout the world to have adverse effects in a variety of areas. It had a negative impact on hospital costs and the length of hospital stay in the field of bone and soft tissue tumor treatment.Copyright: © 2023 Ban et al.
