Incidence and medical complications of COVID-19 in the total laryngectomy population: A population-based study.

OBJECTIVES: Laryngeal and hypopharyngeal cancers treated with total laryngectomy (TL) may provide a unique avenue for COVID-19 to infect cancer patients. The objective of this investigation was to identify incidence of COVID-19 infection and potential complications in TL patients. MATERIALS AND METHODS: Data was extracted from TriNetX COVID-19 research network from from 2019 to 2021 and ICD-10 codes were utilized to query for laryngeal or hypopharyngeal cancer, and outcomes of interest. Cohorts were propensity score-matched based on demographics and co-morbidities. RESULTS: A query of active patients in TriNetX from January 1, 2019 to December 31, 2021 identified 36,414 patients with laryngeal or hypopharyngeal cancer out of the 50,474,648 active patients in the database. The overall COVID-19 incidence in the non-laryngeal or hypopharyngeal cancer population was 10.8% compared to 18.8% (p < 0.001) in the laryngeal and hypopharyngeal cancer group. Those who underwent TL had a statistically significant increased incidence of acquiring COVID-19 (24.0%) when compared to those without TL (17.7%) (p < 0.001). TL patients with COVID-19 had a higher risk of developing pneumonia RR (risk ratio) 1.80 (1.43, 2.26), death 1.74 (1.41, 2.14), ARDS 2.42 (1.16, 5.05), sepsis 1.77 (1.37, 2.29), shock 2.81 (1.88, 4.18), respiratory failure 2.34 (1.90, 2.88), and malnutrition 2.46 (2.01, 3.01) when matched with those COVID-19 positive cancer patients without TL. CONCLUSIONS: Laryngeal and hypopharyngeal cancer patients had a higher rate of acquiring COVID-19 than patients without these cancers. TL patients have a higher rate of COVID-19 compared to those without TL and may be at a higher risk for sequalae of COVID-19.

The effect of COVID-19 pandemic on laryngeal cancer in a tertiary referral center.

PURPOSE: This study aimed to evaluate whether there was a significant change in the laryngeal cancer stage before and after the COVID-19 pandemic. METHODS: This retrospective cohort study was conducted to evaluate the data of patients who operated due to laryngeal cancer in a tertiary referral hospital's ear, nose, and throat (ENT) department between June 2018 and 2021. The patients were included at the same period of the years to rule out any seasonal changes. The basic characteristic, tumor localization, and TNM stage of the patients were compared. RESULTS: 97 patients were operated due to laryngeal cancer during the time period reviewed. 57 (58.8%) patients were operated before and 40 (41.2%) after the COVID-19 pandemic. When comparing the patients before and after the COVID-19 pandemic period, the mean age significantly differed between the study groups that older age was observed in patients who admitted before the COVID-19 pandemic (62.8 ± 6.5 vs. 57.3 ± 6.8, p < 0.001). Regarding the TNM classification, the patients in the after COVID-19 pandemic group had higher rates of T4 stage laryngeal cancer compared to before COVID-19 pandemic group (12 (30%) vs. 4 (7%), p: 0.003). CONCLUSION: Younger patients have operated after the COVID-19 pandemic, and the patients were presented with larger tumor sizes. The pandemic may increase the time between diagnosis and surgery in laryngeal cancer patients.

Impact of the COVID-19 pandemic on the stage and the type of surgical treatment of laryngeal cancer.

PURPOSE: Changes in the entire health care system during COVID-19 epidemic have affected the management of patients with head and neck cancer and posed several clinical challenges for ENT surgeons. Therefore, the present study aimed to investigate the effect of COVID-19 on the stage and the type of surgical treatments used in laryngeal cancer (including total laryngectomy, supracricoid partial laryngectomy (SCPL) and transoral laser microsurgery (TLM)) and also to compare the results of April 2020 to April 2021 with the previous year. MATERIALS AND METHODS: This cross-sectional study was performed on all patients with a diagnosis of laryngeal cancer who underwent surgery in the tertiary care center from April 2020 to April 2021 and the year before the pandemic in the same time. Demographic, cancer stage, and treatment data of all patients were recorded and analysis in two groups. RESULTS: Patients referred at the time of the virus outbreak; 111 were male and 5 were female, and in the group of patients referred before COVID-19, 90 were male and 12 were female. The type of surgical treatment of laryngeal cancer, mean time elapsed from sampling to surgery, stage of disease and mean tumor volume was statistically significant differences in patients before and during the outbreak. CONCLUSION: Patients who referred for diagnosis and treatment at the time of COVID-19 outbreak had more advanced stages of the disease and also the tumor volume was higher in them than patients who had referred before the outbreak. It is necessary to provide new solutions, education and treatment management for patients with laryngeal cancer in such pandemics.

Reduction in healthcare services during the COVID-19 pandemic: Patient screening based on symptoms is an effective strategy for avoiding delayed laryngeal cancer diagnosis.

OBJECTIVE: Restriction in healthcare services during the COVID-19 pandemic caused delays in the diagnosis and treatment of several diseases. To overcome the risk of missed diagnosis of head and neck cancers, before deleting the scheduled appointments, we have introduced a selection of the patients by examining the clinical presenting issue and previous medical history. The aim of this study is to show the effects of the abovementioned strategy on the diagnosis and management of laryngeal cancer. METHODS: Data were extracted from the Hospital software regarding the new diagnosis of laryngeal SCC in the periods from March 2020 to December 2020 during the pandemic (study group) and from March 2019 to December 2019 (control group) were collected. Data were compared regarding: TNM stage, time from first medical examination to histological diagnosis (Time-1), and time form histological diagnosis to beginning of treatments (Time-2). RESULTS: The final study group was composed by 19 laryngeal cancers, the control group by 25 cases. No significant differences were found in the tumour stage between the groups. In the study group, Time-1 was shorter (24 days versus 43 days, p = 0.012), while Time-2 in surgically-treated patients was longer (20 days versus 9 days, p = 0.012). CONCLUSION: During the pandemic, there was a dramatic lack of medical and nurse staff needed for surgical procedures. As consequence, the time between the diagnosis of malignancy and surgical treatment increased. In our unit, an efficient patient selection strategy to reschedule medical appointments avoided a dangerous shift toward higher laryngeal cancer stages.

Patients With Voice Prosthesis Rehabilitation During the COVID-19 Pandemic: Analyzing the Effectiveness of Remote Triage and Management.

OBJECTIVE: To describe a remote approach used with patients with voice prosthesis after laryngectomy during the COVID-19 pandemic and the resulting clinical outcomes in terms of voice prosthesis complications management, oncological monitoring, and psychophysical well-being. STUDY DESIGN: Prospective cohort study. SETTING: Otolaryngology Clinic of the University Polyclinic A. Gemelli, IRCCS Foundation. SUBJECTS AND METHODS: All patients with voice prosthesis who underwent laryngectomy followed by our institute were offered enrollment. Patients who agreed to participate were interviewed to inquire about the nature of the need and to plan a video call with the appropriate clinician. Before and 1 week after the clinician's call, patients were tested with the Hospital Anxiety and Depression Scale. Degrees of satisfaction were investigated with a visual analog scale. A comparison between those who accepted and refused telematic support was carried out to identify factors that influence patient interest in teleservice. RESULTS: Video call service allowed us to reach 37 (50.68%) of 73 patients. In 23 (62.16%) of 37 cases, the video call was sufficient to manage the problem. In the remaining 14 cases (37.83%), an outpatient visit was necessary. Participants who refused telematic support had a significantly shorter time interval from the last ear, nose, and throat visit than patients who accepted (57.95 vs 96.14 days, P = .03). Video-called patients showed significantly decreased levels of anxiety and depression (mean Hospital Anxiety and Depression Scale total score pre- vs post-video call: 13.97 vs. 10.23, P < .0001) and reported high levels of satisfaction about the service. CONCLUSION: Remote approach may be a viable support in the management of patients with voice prosthesis rehabilitation.

Time to Surgery and Survival in Head and Neck Cancer.

BACKGROUND: The COVID-19 pandemic has required triage and delays in surgical care throughout the world. The impact of these surgical delays on survival for patients with head and neck squamous cell carcinoma (HNSCC) remains unknown. METHODS: A retrospective cohort study of 37 730 patients in the National Cancer Database with HNSCC who underwent primary surgical management from 2004 to 2016 was performed. Uni- and multivariate analyses were used to identify predictors of overall survival. Bootstrapping methods were used to identify optimal time-to-surgery (TTS) thresholds at which overall survival differences were greatest. Cox proportional hazard models with or without restricted cubic splines were used to determine the association between TTS and survival. RESULTS: The study identified TTS as an independent predictor of overall survival (OS). Bootstrapping the data to dichotomize the cohort identified the largest rise in hazard ratio (HR) at day 67, which was used as the optimal TTS cut-point in survival analysis. The patients who underwent surgical treatment longer than 67 days after diagnosis had a significantly increased risk of death (HR, 1.189; 95% confidence interval [CI], 1.122-1.261; P < 0.0001). For every 30-day delay in TTS, the hazard of death increased by 4.6%. Subsite analysis showed that the oropharynx subsite was most affected by surgical delays, followed by the oral cavity. CONCLUSIONS: Increasing TTS is an independent predictor of survival for patients with HNSCC and should be performed within 67 days after diagnosis to achieve optimal survival outcomes.

Tracheoesophageal voice prosthesis management in laryngectomy patients during the COVID-19 pandemic.

With the COVID-19 pandemic, there has been significant changes and challenges in the management of oncology patients. One of the major strategies to reduce transmission of the virus between patients and healthcare workers is deferral of follow-up visits. However, deferral may not be possible in total laryngectomy patients. Urgent procedures may be necessary to prevent complications related to ill-fitting tracheoesophageal puncture (TEP) voice prostheses, such as aspiration or loss of voicing. In this paper, we describe the Princess Margaret Cancer Center's approach to managing this unique patient population.

COVID-19 and Total Laryngectomy-A Report of Two Cases.

OBJECTIVE: To date, no cases have been reported on the effects of COVID-19 in laryngectomees. CASE PRESENTATION: We herein presented two clinical cases of laryngectomized patients affected by COVID-19, detailing their clinical course and complications. DISCUSSION: In our experience, permanent tracheostomy did not significantly affect the choice of treatment. However, dedicated devices and repeated tracheal toilettes may be needed to deal with oxygen-therapy-related tracheal crusting. CONCLUSION: In conclusion, laryngectomees should be considered a vulnerable population that may be at risk for worse outcomes of COVID-19 due to anatomical changes in their airways. The role of the ENT specialist is to guide airway management and inform the support-staff regarding specific needs of these patients.

Risk of Virus Contamination Through Surgical Smoke During Minimally Invasive Surgery: A Systematic Review of the Literature on a Neglected Issue Revived in the COVID-19 Pandemic Era.

CONTEXT: The coronavirus disease 2019 (COVID-19) pandemic raised concerns about the safety of laparoscopy due to the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diffusion in surgical smoke. Although no case of SARS-CoV-2 contagion related to surgical smoke has been reported, several international surgical societies recommended caution or even discouraged the use of a laparoscopic approach. OBJECTIVE: To evaluate the risk of virus spread due to surgical smoke during surgical procedures. EVIDENCE ACQUISITION: We searched PubMed and Scopus for eligible studies, including clinical and preclinical studies assessing the presence of any virus in the surgical smoke from any surgical procedure or experimental model. EVIDENCE SYNTHESIS: We identified 24 studies. No study was found investigating SARS-CoV-2 or any other coronavirus. About other viruses, hepatitis B virus was identified in the surgical smoke collected during different laparoscopic surgeries (colorectal resections, gastrectomies, and hepatic wedge resections). Other clinical studies suggested a consistent risk of transmission for human papillomavirus (HPV) in the surgical treatments of HPV-related disease (mainly genital warts, laryngeal papillomas, or cutaneous lesions). Preclinical studies showed conflicting results, but HPV was shown to have a high risk of transmission. CONCLUSIONS: Although all the available data come from different viruses, considering that the SARS-CoV-2 virus has been shown in blood and stools, the theoretical risk of virus diffusion through surgical smoke cannot be excluded. Specific clinical studies are needed to understand the effective presence of the virus in the surgical smoke of different surgical procedures and its concentration. Meanwhile, adoption of all the required protective strategies, including preoperative patient nasopharyngeal swab for COVID-19, seems mandatory. PATIENT SUMMARY: In this systematic review, we looked at the risk of virus spread from surgical smoke exposure during surgery. Although no study was found investigating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or any other coronavirus, we found that the theoretical risk of virus diffusion through surgical smoke cannot be excluded.

Care of immunocompromised patients with head and neck cancer during the COVID-19 pandemic: Two challenging and informative clinical cases.

BACKGROUND AND METHODS: There is an added level of complexity in the management of head and neck cancer patients with underlying immunosuppressive disorders during the COVID-19 pandemic. Head and neck oncologists are tasked with balancing the dual risks of cancer progression in the setting of impaired tumor immunity and increased susceptibility to life-threatening complications from exposure to viral infection for patients and providers. Through two cases of immunocompromised patients with newly diagnosed head and neck malignancies, we aim to provide guidance to clinicians struggling with how to best counsel and manage this unique subset of patients under these difficult circumstances. RESULTS: After careful consideration of the options, we took different approaches in the care of these two patients. CONCLUSIONS: Ultimately, there is no uniform set of rules to apply to this heterogeneous group of immunocompromised patients. We provide some general principles to help guide patient management during the current pandemic.
