Infection Control of 2019 Novel Corona Virus Disease (COVID-19) in Cancer Patients undergoing Radiotherapy in Wuhan
Abstract
Background
A pandemic of 2019 novel corona virus disease (COVID-19), which was first reported in Wuhan city, has affected more than 100,000 patients worldwide. Patients with cancer are at a higher risk of COVID-19, but currently, there is no guidance on the management of cancer patients during this outbreak. Here, we report the infection control measures and early outcomes of patients who received radiotherapy (RT) at a tertiary cancer centre in Wuhan.
Methods
We reviewed all patients who were treated at the Zhongnan Hospital of Wuhan University (ZHWU) from Jan 20 to Mar 6, 2020. This preceded the city lock-down date of Jan 23, 2020. Infection control measures were implemented, which included a clinical pathway for managing suspect COVID-19 cases, on-site screening, modifications to the RT facility, and protection of healthcare workers. Primary end-point was infection rate among patients and healthcare staff. Diagnosis of COVID-19 was based on the 5th edition criteria.
Findings
209 patients completed RT during the study period. Median age was 55 y (IQR = 48-64). Thoracic, head and neck, and lower gastrointestinal and gynaecological cancer patients consisted the majority of patients. Treatment sites included thoracic (38.3%), head and neck (25.4%), and abdomen and pelvis (25.8%); 47.4%, 27.3%, and 25.4% of treatments were for adjuvant, radical, and palliative indications, respectively. 188 treatments/day were performed prior to the lock-down, in contrast to 12.4 treatments/day post-lock-down. Only one (0.48%) patient was diagnosed with COVID-19 during the study period. No healthcare worker was infected.
Interpretation
Herein, we show that in a susceptible population to COVID-19, strict infection control measures can curb human-to-human transmission, and ensure timely delivery of RT to cancer patients.
Funding
This study was funded by Health Commission of Hubei Province Scientific Research Project, WJ2019H002, Health Commission of Hubei Province Medical Leading Talent Project.
Research in context
Evidence before this study
The 2019 novel coronavirus disease (COVID-19) is now a global pandemic. Cancer patients are at risk of COVID-19 pneumonia, and thus infection control measures are crucial to mitigate their risk of infection. We searched PubMed and Medline for articles published up to Mar 12, 2020, using the following keywords: “COVID-19”, “SARS”, “SARS-CoV-2”, “infection control”, and “cancer”. No evidence exists that informs on the appropriate infection control measures for COVID-19.
Added value of this study
We report our single centre experience on the detailed infection control measures that were undertaken to minimise cross transmission between cancer patients undergoing radiotherapy, and between patients and healthcare workers. Measures entailing screening of suspect cases, re-organisation of the treatment facility, and protection of healthcare workers were described. With our infection control protocol, we recorded only one COVID-19 case among the 209 patients (0.48%) who were treated at our centre during the period of Jan 20 to Mar 6, 2020. No healthcare worker was affected.
Implications of all the available evidence
The effective infection control measures outlined in this study will help institutions worldwide affected by COVID-19 to formulate guidelines to mitigate nosocomial human-to-human transmission, especially among susceptible patients.
