Patients with NwAfib perioperatively have increased risk of stroke and early death after discharge independent of other clinical risk factors.

BackgroundTo assess the functional donor site morbidity of the forearm free flap in patients surviving at least 2 years after ablative head and neck cancer surgery in a tertiary care centre.MethodsThis study involved nine long-term survivors (2 year post-operative) who had forearm free flaps to reconstruct head and neck defects. All flaps were raised from the non-dominant arm. The non-donor side acted as a control for all patients. Objective measurements were as follows: grip, tip pinch and key pinch strength measured with dynamometers; flexion, extension, radial and ulnar deviation and pronation and supination range of motion at the wrist measured with goniometry; A timed manual dexterity task was performed with a grooved pegboard test, and sensation of the radial nerve was tested with Semmes Weinstein monofilaments. Subjective measurements included a validated patient questionnaire of hand function and opinions of scar appearance as well as a validated scar assessment from two different observers.ResultsPronation at the wrist, manual dexterity and sensation were found to be significantly reduced in the donor side compared to the non-donor side. Inter-rater agreement between the two observers was found to be poor, except for an acceptable correlation between overall scar opinions. No correlations were found between any subjective or objective items or between the patient’s and the observers’ subjective evaluations.ConclusionsDonor site morbidity can be demonstrated with objective testing however this is accepted and well tolerated by head and neck cancer patients.

Objective Evaluate the oncologic outcomes and cost analysis of transitioning to a specimen oriented intraoperative margin assessment protocol from a tumour bed sampling protocol in oral cavity (OCSCC) and oropharyngeal squamous cell carcinoma (OPSCC). Study design Retrospective case series and subsequent prospective cohort study Setting Tertiary care academic teaching hospital Subjects and methods Retrospective case series of all institutional T1-T2 OCSCC or OPSCC treated with primary surgery between January 1st 2009 – December 31st 2014. Kaplan-Meier survival estimates with log rank tests were used to compare patients based on final margin status. Cost analysis was performed for escalation of therapy due to positive final margins. Following introduction of a specimen derived margin protocol, successive prospective cohort study of T1-T4 OCSCC or OPSCC treated with primary surgery from January 1st 2017 – December 31st 2018. Analysis and comparison of both protocols included review of intraoperative margins, final pathology and treatment cost. Results Analysis of our intra-operative tumour bed frozen section protocol revealed 15 of 116 (12.9%) patients had positive final pathology margins, resulting in post-operative escalation of therapy for 14/15 patients in the form of re-resection (7/14), radiation therapy (6/14) and chemoradiotherapy (1/14). One other patient with positive final margins received escalated therapy for additional negative prognostic factors. Recurrence free survival at 3 years was 88.4 and 50.7% for negative and positive final margins respectively (p = 0.048). Implementation of a specimen oriented frozen section protocol resulted in 1 of 111 patients (0.9%) having positive final pathology margins, a statistically significant decrease (p < 0.001). Utilizing our specimen oriented protocol, there was an absolute risk reduction for having a final positive margin of 12.0% and relative risk reduction of 93.0%. Estimated cost avoidance applying the specimen oriented protocol to our previous cohort was $412,052.812017 CAD. Conclusion Implementation of a specimen oriented intraoperative margin protocol provides a statistically significant decrease in final positive margins. This change in protocol leads to decreased patient morbidity by avoiding therapy escalation attributable only to positive margins, and avoids the economic costs of these treatments.

As the COVID-19 pandemic continues to unfold, guidelines related to the delivery of medical and cancer care are being disseminated in an effort to flatten the curve of transmission while continuing to provide appropriate guideline based care for cancer patients. Head and neck squamous cell carcinoma (HNSCC) is unique in its location in the upper aerodigestive tract, a known location that harbors SARS-Cov2, the causative virus in COVID-19. Otolaryngologists and associated multidisciplinary team members caring for head and neck cancer patients are at heightened risk of transmission through mucus, blood, and aerosolized particles. A high rate of transmission to otolaryngologists has been reported in China, Italy, and Iran, with reports of morbidity and death [1]. The limited availability of COVID-19 testing, personal protective equipment (PPE), disposable medical supplies, hospital and ICU beds, ventilators, and ancillary staff force clinicians to triage which procedures are "essential" and which can be safely delayed. Healthcare providers who contract the virus have generally been mandated to selfquarantine, thereby reducing the availability of the hospital workforce. In the midst of the ongoing pandemic, patients diagnosed with HNSCC now have the added stress in how COVID-19 will impact their care and treatment. The current evidence supports that cancer patients have a higher risk of infection and serious complications from COVID-19 relative to other patient subgroups [2]. Uncertainties such as whether treatment will continue and how these high risk patients will continue to access services, are being addressed as the situation continues to evolve. Patients, physicians, health care workers, health care systems, ethicists, and attorneys among others have become aware of the number of complex dilemmas and issues that have arisen during this pandemic that include but are not limited to the following:

Objective To characterize pharyngocutaneous fistula (PCF) rates and functional outcomes following microvascular free tissue transfer (MVFTT) reconstruction of salvage total laryngectomy (STL) with a review of two different flap inset techniques and a review of the literature. Methods Retrospective review. Results Review of the literature revealed 887 patients who underwent STL MVFTT from 14 references. Ninety‐six STL MVFTTs were performed by the authors, with 36 (38%) patients undergoing multilayer fascial underlay (MLFU) closure and 60 (62%) a standard single layer closure (SLC). One (3%) PCF occurred in the MLFU group compared to 12 (20%) in the SLC cohort (P = .03). Postoperative gastrostomy (G)‐tube dependence was lower following MLFU closure compared to SLC (25% vs. 57%, P < .01), whereas pharyngoesophageal stricture (PES) (28% vs. 38%), tracheoesophageal puncture (TEP) placement (42% vs. 42%), and TEP usage (87% vs. 88%) did not significantly differ (P > .05). Compared to pooled rates from the literature, patients who underwent a MLFU MVFTT inset technique demonstrated significantly lower PCF incidence (3% vs. 23%, P < .01) without significant differences in PES (28% vs 23%, P = .55), G‐tube dependence (25% vs. 23%, P = .25), or TEP placement (42% vs. 59%, P = .09). Conclusion Despite MVFTT reconstruction after STL, G‐tube dependence, PCF formation, and limitations of speaking rehabilitation (TEP) remain a significant issue. Modification of MVFTT inset may provide an opportunity to reduce PCF incidence without affecting other functional outcomes. Level of Evidence 4 Laryngoscope, 131:E875–E881, 2021

Cartilage tympanoplasty provides a safe and accessible surgical option for the treatment of PET and significantly reduces the symptoms of autophony, conducted breath sounds, and aural fullness. Further studies are needed to investigate whether addressing PET symptoms simultaneously from both the tympanic membrane and the eustachian tube orifice can improve patient symptoms even further.

Introduction The abscopal effect is a rarely observed outcome of radiotherapy wherein there is a reduction in metastatic disease burden outside of the targeted treatment area. Likely due to an in situ vaccine effect of radiother­apy, the abscopal effect may be augmented by immunotherapy. This report is the first case of the abscopal effect observed in metastatic head-and-neck squamous cell carcinoma (hnscc) treated with concurrent radiotherapy and single-agent nivolumab. Case Description An otherwise healthy 57-year-old man underwent craniofacial resection and adjuvant chemo­radiotherapy for advanced sinonasal squamous cell carcinoma. Distant metastatic disease developed shortly after primary treatment, and immunotherapy in the form of nivolumab was initiated. Subsequent oligometastatic progres­sion despite immunotherapy prompted palliative radiotherapy to a single metastasis due to pending symptomatology. Post-radiotherapy, the abscopal effect was observed with all distant sites of metastatic disease shrinking. Five months following treatment, a sustained reduction in disease burden has been demonstrated. Summary We present the first case of the abscopal effect in a patient with metastatic hnscc treated with palliative radiotherapy concurrent with single-agent nivolumab immunotherapy, and only the third case of the abscopal effect in metastatic head-and-neck cancer. Dual treatment with immunotherapy and radiotherapy may be an important treatment option in the future, mediated through the abscopal effect.

BackgroundThe laryngeal framework provides a natural barrier preventing tumour spread to extralaryngeal structures. Transoral laser microsurgery (TLM) for laryngeal squamous cell carcinoma (SCC) may violate these boundaries, altering the pathways of tumor spread for potential recurrences. Our project objective is to describe laryngeal SCC recurrence patterns and overall survival in patients requiring total laryngectomy (TL) after TLM.MethodsPatients undergoing TLM for laryngeal SCC requiring salvage TL were identified from a prospective CO2 laser database containing all patients undergoing TLM for head and neck malignancies at the QEII Health Sciences Center in Halifax, Nova Scotia between March 2002 – May 2014. Surgical pathology reports were analyzed for tumor characteristics, extent of recurrence and invasion of local structures. Kaplan-Meier analyses were performed to evaluate overall survival, disease specific survival (DSS) and locoregional control.ResultsFifteen patients were identified from the database as receiving salvage TL for recurrent disease after initial TLM resection for laryngeal SCC. Final pathology reports demonstrated that 67% (10/15) of patients had thyroid cartilage involvement while 53% (9/15) of patients had cricoid cartilage involvement on salvage TL pathology. 33% (5/15) of patients had perineural invasion and 27% (4/15) had lymphovascular invasion. Mean and median follow-up times were 36.7 months and 26.8 months respectively (range 3.9–112.6). The Kaplan-Meier estimate for overall survival at 36 months was 40% post TL with a standard error (SE) of 13.6%. DSS was 47% (SE 14.2%), and locoregional control was 55% (SE 14.5%) post TL.ConclusionsLaryngeal recurrence sites following TLM seem to be consistent with historical data at known laryngeal sites of vulnerability. Treatment with TLM does not predispose patients to a lower rate of locoregional control and overall survival after total laryngectomy and salvage outcomes are consistent with literature values.
