Those utility coefficients will be later exploited in an economic evaluation study comparing the two approaches. METHODS: The above cited economic evaluation will be done from the Swiss healthcare system perspective and, as such, Swiss healthcare professionals were interviewed to elicit utility coefficients...

PURPOSE/OBJECTIVE(S): Recent landmark trials have suggested a survival benefit to definitive tumor directed therapies (DTDT) for selected patients with metastatic disease for various malignancies. We sought 1) to confirm the prognostic significance of metachronous oligometastatic burden for human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) and 2) to evaluate disease outcomes for oligometastatic HPV-associated OPSCC after upfront DTDT versus upfront systemic therapy...

PURPOSE/OBJECTIVE(S): This study sought to measure circulating plasma tumor-tissue modified human papilloma virus DNA (TTMV-HPV DNA) and kinetics following trans-oral robotic surgery (TORS), neck dissection, and adjuvant (chemo)radiation for p16+ oropharyngeal squamous cell carcinoma (OPSCC). MATERIALS/METHODS: Patients with p16+ OPSCC currently enrolled on an ongoing phase II clinical trial investigating radiation dose de-intensification following TORS and neck dissection (TORS version 2...

OBJECTIVES: To assess the prognostic significance of oligometastatic versus polymetastatic disease in human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC), and to evaluate the impact of definitive tumor directed therapy on the survival outcomes for patients with oligometastatic disease when compared to systemic therapy. MATERIALS AND METHODS: This was a retrospective observational cohort study of patients with HPV-associated OPSCC who developed distant metachronous metastatic disease after undergoing initial primary surgical management from 2008 to 2017...

Pediatric transoral robotic surgery (TORS) has improved from 2007 to 2020, widening its indications and feasibility. This article aims to systematically analyze the procedures performed from the first use until the current year, observing their evolution over time. A systematic literature review was performed using PubMed, Scopus, Web of Science, and Cochrane databases between March 1, 2000, and April 1, 2020. We selected studies that were written only in English and were performed in live human subjects. About 16 studies were found with a total of 73 subjects treated, among them 41 were men and 32 were women with an average age of 6...

BACKGROUND: Trans-oral robotic surgery (TORS) and primary radiotherapy are the two modalities used to treat early T stage oropharyngeal squamous cell carcinoma(OPSCC). Prior literature including a recent randomized controlled trial have not shown the superiority of one modality over the other. When the modalities have similar outcomes, cost-effectiveness have an important role in deciding on the appropriate treatment. There are economic evaluations comparing the two modality with contradicting conclusions...

Trans-oral robotic surgery for head and neck cancers can be performed using rigid, multi-port robots with linear access but the Medrobotics Flex® system offers an alternative as it is endo-luminal, single-port, and uses flexible instruments. To assess the utility of the Medrobotics Flex® system for head and neck cancer (HNC) resections. A retrospective review of all HNC resections done over a 2.5-year period (Jan 2017-July 2019) at the Memorial Hospital, using the Flex® system. Data collected include patient demographics, tumour site, tumour stage, p16 status, smoking history, surgery performed, histologic margins, complications, overall survival, recurrence, and adjuvant treatments received...

Over the past decade, the incidence of thyroid cancer has rapidly increased worldwide, and thyroid surgery has become one of the most common performed surgical procedure. Even though conventional open thyroidectomy remains the gold standard, this approach leaves a neck scar which could be worrying mainly for young women. The recent progress in surgical technology, as well as patient cosmetic requests, have led to the development of alternative access to the thyroid lodge. Thus, alternative techniques have been established in order to potentially provide a more appealing cosmetic result, both with a minimally-invasive cervical or remote-access approach...

OBJECTIVE: Trans Oral Robotic Surgery (TORS) is a modality in the management of oropharyngeal squamous cell carcinoma(OPSCC). This study was planned to determine whether Selective Neck Dissection (SND) is oncological safe procedure even in patients with lymph node metastases. METHODS: OPSCC patients were divided into Modified Radical Neck Dissection (MRND) and SND groups. The outcome measures were overall survival (OS), disease-free survival (DFS) and regional recurrence free survival (RRFS)...

OBJECTIVES: To determine whether up-front trans-oral robotic surgery (TORS) for clinically-staged locally-advanced human papillomavirus (HPV)-related oropharyngeal cancer is associated with oncologic and survival outcomes comparable to early-stage (cT1/T2) tumors. MATERIALS AND METHODS: Retrospective cohort study of 628 patients with HPV-related oropharyngeal cancer who underwent up-front TORS from 2007 to 2017. Patients were stratified into two cohorts based on early-stage (cT1/2) versus locally-advanced (cT3/4) tumor at presentation...

BACKGROUND: Trans-oral robotic surgery (TORS) facilitates surgical resection of tumours as an alternative to open surgery and has demonstrated favourable oncological results. Given the novelty of TORS and the paucity of evidence on TORS-specific complications in a rural setting, we report our experience with TORS at an Australian rural head and neck centre. METHODS: A retrospective review of all robotic cases performed at a regional head and neck centre in Queensland was undertaken from 2014 to 2019...

Trans Oral Robotic Surgery (TORS) is an emerging technique that provides several benefits over existing treatment regimens for head and neck cancer, including smaller incisions, less bleeding, shorter term inpatient hospitalization, and reduced intensive care unit (ICU) length of stay. TORS allows a high resolution, magnified, three-dimensional wide view of the surgical field through an endoscope, avoiding large external cervical incisions and split-lip mandibulotomy, usually required in cancer surgeries of the oropharynx...

This study describes a novel approach in the reduction of SARS-CoV-2 transmission during trans-oral robotic surgery (TORS). Eight patients underwent TORS between 01 February 2020 and 07 September 2020. A sterile plastic sheet draped over sterile supports with water-tight seal around each cannula was used to create a sterile working space within which the robotic arms could freely move during operation. This set-up acts as an additional physical barrier against droplet and aerosol transmission. Operative diagnosis; droplet count and distribution on plastic sheet and face shields of console and assistant surgeons, and scrub nurse were documented...

BACKGROUNDS: Pathologic features of oropharyngeal squamous cell carcinoma (OPSCC) treated with trans-oral robotic surgery predict prognosis and adjuvant therapy. We hypothesized that pathologic muscle invasion (pMI) is associated with poor pathological markers. METHODS: Retrospective review of surgically treated OPSCC to identify pMI and its association with poor pathologic markers. RESULTS: pMI was present in 12/37 patients, and compared to non-pMI, was associated with higher rates of lymphovascular invasion (75% vs...

Human papillomavirus is responsible of approximately 70% oropharyngeal tumours and is related with more favourable outcomes. It has led to an increasing interest for de-escalation treatment strategies such as Trans Oral Robotic Surgery (TORS). A literature review was performed searching for the role of TORS as de-escalation modality of treatment in patients with p16 positive oropharyngeal squamous cell carcinoma (OPSCC). Special attention was paid to the potential advantage offered by TORS in reducing adjuvant radiation therapy...

A man in his mid 70s was referred to head and neck outpatients with bulky tissue in the left tonsillar fossa. He had previously been treated for oligometastatic renal clear cell carcinoma (diagnosed over 15 years prior to disease recurrence) by tonsillectomy and adjuvant radiotherapy (years from primary treatment), followed by trans-oral laser surgery to his oropharyngeal recurrence 3 years later. Examination under anaesthetic and biopsy confirmed further recurrence of disease in the left tonsillar fossa, with parapharyngeal extension, which has not been previously reported in the literature...

PURPOSE: No study to date has described the overall landscape of sleep disorders management and training in otolaryngology departments of different countries. The aim of our study was to investigate and compare settings, diagnostic and therapeutic approaches and training programmes. METHODS: An international online survey was developed with the collaboration of the YO-IFOS (Young Otolaryngologists-International Federation of Otorhinolaryngological Societies) to assess the current practice of otolaryngologists in the management of sleep disorders...

Trans-oral robotic surgery (TORS) has emerged as an important surgical treatment option in the management of human papillomavirus (HPV)-positive and -negative oropharynx cancer. However, treatment selection is paramount to ensure that patients will not require multimodality adjuvant therapy. In this study, we determined predictors of adjuvant therapy in TORS-treated patients. The National Cancer Database (NCDB) was used to identify patients with newly diagnosed clinical T1-T4, N0-N3 oropharyngeal squamous cell carcinoma who underwent TORS between 2010-2016...
