Impact of COVID-19 on Disease Progression and Postoperative Complications in Patients with Head and Neck Cancer

Abstract

The COVID-19 pandemic has created a remarkable challenge for the healthcare system. The delayed presentation, diagnosis, and treatment of head and neck cancer during the COVID-19 pandemic is expected to adversely affect outcomes. COVIDSurg collaborative group in 2020 concluded surgery ≥ 4 weeks after a positive COVID-19 swab result was associated with a lower risk of postoperative mortality. The aim of this study is to assess the disease progression due to COVID-19 infection in patients with head and neck cancer planned for surgery and to analyze the postoperative complications in head and neck cancer patients who underwent surgery after COVID-19 infection. This is an ambispective observational study and included patients with head and neck cancer who recovered from COVID-19 infection and underwent surgery from June 2020 to May 2022. There were a total of 1849 patients with head and neck cancer operated in the mentioned study period during COVID-19 pandemic. One hundred fifty-nine patients had documented COVID-19 infection. One hundred two patients had oral cavity carcinoma (64%), and 38 patients had thyroid carcinoma (23.8%). Early disease was noted in 49 patients (30.8%) and locally advanced disease in 108 patients (67.9%). Mean duration of delay in surgery was 4 weeks. Disease progression was noted in 27 patients (17%) out of which 15 patients were inoperable. Thirty-seven out of 159 patients (23%) had postoperative complications, and it included 2 mortality. There was increased trend noted in pulmonary complications and hemorrhage when compared to pre-COVID-19 era. Due to COVID-19 pandemic, delayed elective head and neck cancer surgery has resulted in higher rates of inoperability. COVID-19 has been associated with increased postoperative pulmonary complications and hemorrhage.

Impact of the COVID-19 Infection on Head and Neck Cancer Treatment During Hospitalization

“…In the head and neck region, there may be a risk of upper respiratory tract symptoms due to COVID-19 infection and associated deterioration of the general condition. In addition to the early reports of the COVID-19 pandemic [13], Koizumi et al [14] reported on the impact of the COVID-19 pandemic on the number of otolaryngological surgeries, and Nadarajan et al [15] reported on the association between surgical complications and COVID-19. Nevertheless, to the best of our knowledge, there are no reports documenting the influence of COVID-19 on managing head and neck malignancies in the inpatient setting (as per a PubMed title search employing the query "COVID-19 head and neck cancer hospitalization").…”
