Early detection of recurrent HPV+ hypopharyngeal squamous cell carcinoma by circulating tumor DNA

Circulating tumor DNA is a liquid biomarker that offers a highly specific method to assess HPV-associated tumor burden via a blood draw. It has the potential for many clinical applications in cancer care, including prognostication, monitoring treatment response, and surveillance for disease recurrence. In this case report, we present a case of recurrent HPV-associated hypopharyngeal squamous cell carcinoma first detected by circulating tumor HPV DNA that demonstrates the role of circulating tumor HPV DNA tests in posttreatment surveillance and the utility of HPV testing in all HPV-mediated tumors, regardless of subsite.Copyright © 2023 Elsevier Inc.

Forging clinical collaborations and cooperation in overcoming challenges for non-COVID-19 patients during COVID-19 times: Surgical case studies requiring a multidisciplinary and inter-agency approach in Malaysia

The COVID-19 pandemic has brought global health services to a standstill. National healthcare systems and medical staffing in many countries have reached crisis levels due to the phenomenal outbreak. Healthcare resources have been strained to meet the unprecedented numbers of patient admissions with a significant amount of funding and manpower being channelled towards tackling this global pandemic. Despite the rollout of vaccinations, the development of new viral strains has now presented a new challenge. With the inevitable conversion of tertiary public hospitals to specialized COVID-19 centres with 'Full Covid Status' and the mobilization of its doctors from all specialities to care for these patients, the non-COVID-19 patients are becoming more neglected. The lack of elective surgeries performed and non-emergent admissions due to the unavailability of beds and personnel to care for this group of patients are concerning. As most of the focus and resources are now aimed at COVID-19 patients, the need to forge collaborations and cooperation between hospitals, agencies and healthcare systems are pertinent to ensure the provision of quality treatment for those suffering from non-COVID-19 diseases. To highlight this effort in Malaysia, we would like to present 2 case studies of non-COVID-19 patients undergoing elective surgeries through intergovernmental ministerial collaborations and a public-private partnership.Copyright © The Author(s) 2022.

SARS-CoV-2-fertozés okozta Kikuchi-Fujimoto-betegség sikeres gyógyítása.

The Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis) is an autolimited process, which can be caused by viral agents like Epstein-Barr virus, human herpes virus, HIV, B19 parvovirus, paromyxoviruses, SARS-CoV-2, Toxoplasma and Yersinia. The correct diagnosis is based on histological findings. A 45-year-old female patient presented in our ambulatory room with a unilateral neck mass, fever, dysphonia and dysphagia. The patient was double-tested positive for SARS-CoV-2 approximately 1 month before the symptoms started. Before examination, the nasopharyngeal rapid test for SARS-CoV-2 resulted negative. After hospitalization, intravenous antibiotic (Augmentin, 3 × 1.2 g; Klion, 2 × 100 mg) and steroid (Solu-Medrol, 2 × 125 mg) therapy were administered. The neck and chest CT described a right-sided retropharyngeal abscess with bilateral neck lympadenopathy. Urgent tracheotomy, neck dissection and lymph node biopsy were made. The intraoperative findings excluded the presence of the abscess. The histological findings confirmed the necrotizing histiocytic lymphadenitis. Despite of the fact that the Kikuchi-Fujimoto disease is autolimited, we can see that, in this particular case, the lymphadenopathy after the SARS-CoV-2 infection caused a life-threatening situation. The formed extratissular liquid imitated the image of a retropharyngeal abscess. In the searched worldwide literature, similar intervention for this type of process was not described. Tracheotomy, neck dissection and removing the lymph nodes as ,,trigger zones" caused the full recovery of the patient. In the future, we consider important proving and clarifying the correlation between SARS-CoV-2 and Kikuchi-Fujimoto disease. Orv Hetil. 2022; 163(27): 1061-1065.

Implementation of Enhanced Recovery After Surgery (ERAS) in Total Laryngectomies

Aim: The Enhanced Recovery After Surgery (ERAS) protocol for total laryngectomies was first implemented in our tertiary head and neck centre from November 2019. It includes pre-operative carbohydrate loading and an early swallow test which facilitates recommencement of oral intake to improve outcomes. Protocol adherence rate and patient outcomes were measured to determine the effectiveness and benefits of ERAS in laryngectomy patients. Method: 22 total laryngectomy patients from November 2019 to September 2021 were enrolled onto the ERAS protocol, 18 primary and 3 salvage cases. An analysis of the respective patient cohorts was performed to determine adherence to the ERAS protocol and outcomes such as complications and length of inpatient stay were measured. Results: 19 patients (86%) received pre-operative carbohydrate loading successfully, while 3 patients were contraindicated due to background of diabetes. Early swallow test was performed in 59% of patients. Potential reasons for delay were stoma dehiscence or clinical suspicion of neo-pharyngeal leak. 59% of primary cases were deemed medically fit for discharge within the target timeframe of 12-14 days whereas no target was set for salvage cases due to expected poor healing. Main complication in primary cases was neo-pharyngeal leak followed by stoma dehiscence with 28% and 11% respectively. Conclusion: Limitations of our study include small sample size due to the COVID-19 pandemic. Despite its infancy, the ERAS protocol has achieved good outcomes in early recommencement of oral intake post-laryngectomy and encouraging early safe discharge from hospital. Future plans include establishment of Prehab Clinic and application of ERAS to neck dissection patients.

Correlation between imaging and histopathology in head and neck oncology – A retrospective study

Introduction: Tumour size, depth of invasion, type and extent of nodal metastasis are some of the key prognostic indicators in operable head and neck cancers. Initial Imaging with USS of neck and FNAC or core biopsy has been established to have a high sensitivity and specificity. In addition, CT neck and thorax and MRI scan of the primary tumour are recommended as part of staging scans. Information from this work up guides the MDT and patients towards a tailored management plan. We aimed to compare preoperative imaging work up and TNM staging with post-operative histopathology. Methods: We retrospectively reviewed 48 patients who underwent resection and selective neck dissection from January 2020 to August 2021, assessing their initial work up and its adherence to current guidelines. We also evaluated its correlation to final histopathology. Results: 100% compliance was noted with USS and FNAC, 94% compliance with CT and MRI and 96% had incisional biopsy. USS showed a 80 % specificity and a 55% sensitivity. CT had a specificity of 62.5% and sensitivity of 75%. MRI specificity was 58.8% and sensitivity 73.6%. Conclusions: Our results compare favourably to other published data on imaging correlation to histopathology in head and neck oncology. Time lapse between preoperative work-up and surgical resection during COVID pandemic may have led to advanced disease that is not evident on preoperative staging scans. Newer modalities including real time imaging and in-vivo surgical margin assessment remain to be explored.

Assessment of YouTube as an Educational Tool in Teaching Key Indicator Cases in Otolaryngology During the COVID-19 Pandemic and Beyond: Neck Dissection.

OBJECTIVES: YouTube has become the preferred resource for trainees in otolaryngology to prepare for surgery. This study aimed to compare the evaluation by 2 attending physicians and 2 resident physicians of the quality of videos on YouTube on neck dissection, a key indicator case in head and neck surgery. The authors aimed to assess the quality and quantity of YouTube videos available for development of a virtual surgical educational curriculum for trainees in otolaryngology. METHODS: Using the YouTube search feature, the top 10 videos by relevance and view count were compiled using the following search terms: radical neck dissection, selective neck dissection, modified radical neck dissection, lateral neck dissection, levels I-III neck dissection, levels II-IV, left neck dissection, right neck dissection, cervical nodal dissection, and supraomohyoid neck dissection. A total of 37 videos on neck dissection were identified and analyzed using the LAP-VEGaS criteria as well as author-specific modified LAP-VEGaS criteria. RESULTS: The mean comprehensive LAP-VEGaS score was 8.74 (SD 3.10). The majority of videos (24/37) were designated as medium quality; 10 of 37 videos were low quality and 3 of 37 videos were high quality. In the total group analysis, there was excellent inter-rater reliability between attending physicians (Cohen's kappa coefficient of 0.84) and good inter-rater reliability between resident physicians (Cohen's kappa coefficient of 0.58). There was no correlation between total view count, video age, or number of likes/dislikes and the overall LAP-VEGaS score. The presence of audio or written commentary had a moderate positive correlation with LAP-VEGaS score (adjusted R2 of 0.36). There was no statistically significant difference in video quality between videos posted by US and non-US based physicians (95% confidence interval -0.10 to 4.10; p = 0.06). However, videos made by an otolaryngology-trained physician had a LAP-VEGaS score that was 3.93 points higher (95% confidence interval 2.34-5.52; p < 0.001) than that of videos made by a nonotolaryngology-trained physician. CONCLUSIONS: Online videos of neck dissection represent an increasingly ubiquitous and appropriate resource for trainees in learning otolaryngology key indicator cases. While free-to-access video repositories, such as YouTube, have become increasingly popular among trainees as a primary resource for learning and preparing for surgical cases, they lack consistent quality and as such, global efforts should be taken to improve the breadth and depth of educational video content in otolaryngology.

Self-removing passive drain to facilitate postoperative care via telehealth during the COVID-19 pandemic.

BACKGROUND: Telehealth postoperative visits are an attractive strategy to minimize exposure, especially during the SARS-CoV-2 (COVID-19) pandemic. The use of a surgical drain often prevents this minimal-exposure approach in that patients return to the outpatient clinic for drain removal. METHODS AND RESULTS: Following unilateral neck dissection, the customary closed-suction drain was replaced with a self-removing, passive drain dressing to facilitate same-day discharge and telehealth postoperative follow-up. The patient removed the dressing and drain at home during a telehealth visit on postoperative day 4 and she healed favorably without any signs of infection or seroma. CONCLUSIONS: When thoughtfully applied in the appropriate clinical context, small practice adaptations like this can facilitate telehealth solutions that diminish unnecessary exposure for patients, their caregivers, and health care staff.
