Objective: In patients with head and neck squamous cell carcinoma (HNSCC), initiating postoperative radiotherapy (PORT) greater than 42 days after surgery is associated with a higher risk of poor survival outcomes. Social support has been shown to modulate behaviors related to care-seeking and treatment adherence. In this study, we sought to determine the relationship between social support metrics and PORT delays., Study Design: Prospective cohort study., Setting: Single tertiary medical center., Methods: Patients with HNSCC who underwent primary surgical excision requiring PORT were prospectively enrolled. Patient-perceived social support metrics were assessed using the Medical Outcomes Study Social Support Survey (MOS-SSS) at initial presurgical evaluation. Associations with PORT delays were evaluated via univariable and multivariable logistic regression analysis., Results: A total of 111 patients met the inclusion criteria for the study. An additional 28 patients were recommended to receive PORT but did not initiate treatment and were included for secondary analysis. All four subscales of the MOS-SSS (positive social interaction, affectionate support, tangible support, and emotional/informational support) were significantly associated with PORT initiation delays on univariable analysis. On multivariable analysis, the overall MOS-SSS score (odds ratio [OR] 2.08, 1.15-4.35, p = .028) was significantly associated with PORT initiation delays. On secondary analysis, lower tangible support was associated with a lack of PORT initiation (OR 1.63, 1.05-2.54, p = .028)., Conclusion: Social support metrics were significantly associated with PORT delays, which may help promote tighter scheduling and closer monitoring of high-risk patients., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

Objective(s): To evaluate the impact of consistent surgical teams on procedure duration in head and neck free tissue transfer, and to evaluate the length of stay and readmission rates with consistent teams., Methods: A retrospective chart review of head and neck microvascular reconstruction by a single surgeon between August 2017 and November 2021 was performed. Procedure duration, wound complications, length of stay, and 30-day readmissions were analyzed. One circulating nurse (CN) and surgical technologist (ST) were considered "consistent" due to their prior work with the primary surgeon. All others were considered "ad hoc." Teams were "Consistent CN + ST," "Consistent ST," "Consistent CN," or "Ad hoc." Procedure duration between groups was compared via analysis of variance. Multivariate linear regression was performed to predict procedure duration., Results: A total of 135 patients were included. Age, sex, and American Society of Anesthesiologists status did not significantly differ across groups (p = 0.963; p = 0.467; p = 0.908, respectively). The mean procedure duration was 339.3 min and differed significantly across all groups (p = 0.006, Cohen d = 0.32). Compared to the Ad hoc group, consistent teams demonstrated significant reductions in mean procedure duration (Consistent CN + ST: 58.4 min, p = 0.001, Cohen d = 0.67; Consistent ST: 51.6 min, p = 0.013, Cohen d = 0.61; Consistent CN: 44.5 min, p = 0.031, Cohen d = 0.52). Controlling for other factors, the ad hoc team predicted increased procedure duration on multivariate analysis ( β 57.38, 19.92-94.85, p < 0.003). Wound complications, length of stay, and readmission rates did not differ significantly across groups (p = 0.940; p = 0.174; p = 0.935, respectively)., Conclusion: Consistent CN and ST improve operative efficiency in head and neck-free tissue transfer. Future studies may evaluate the impact of team consistency on complications, physician burnout, and health systems costs., Level of Evidence: 3 Laryngoscope, 133:2154-2159, 2023., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

Importance: Timely initiation of postoperative radiation therapy (PORT) is associated with reduced recurrence rates and improved overall survival in patients with head and neck squamous cell carcinoma (HNSCC). Measurement of the association of social-ecological variables with PORT delays is lacking., Objective: To assess individual and community-level factors associated with PORT delay among patients with HNSCC., Design, Setting, and Participants: This prospective cohort study carried out between September 2018 and June 2022 included adults with untreated HNSCC who were enrolled in a prospective registry at a single academic tertiary medical center. Demographic information and validated self-reported measures of health literacy were obtained at baseline visits. Clinical data were recorded, and participant addresses were used to calculate the area deprivation index (ADI), a measure of community-level social vulnerability. Participants receiving primary surgery and PORT were analyzed. Univariable and multivariable regression analysis was performed to identify risk factors for PORT delays., Exposures: Surgical treatment and PORT., Main Outcomes and Measures: The primary outcome was PORT initiation delay (>42 days from surgery). Risk of PORT initiation delay was evaluated using individual-level (demographic, health literacy, and clinical data) and community-level information (ADI and rural-urban continuum codes)., Results: Of 171 patients, 104 patients (60.8%) had PORT delays. Mean (SD) age of participants was 61.0 (11.2) years, 161 were White (94.2%), and 105 were men (61.4%). Insurance was employer-based or public among 65 (38.5%) and 75 (44.4%) participants, respectively. Mean (SD) ADI (national percentile) was 60.2 (24.4), and 71 (41.8%) resided in rural communities. Tumor sites were most commonly oral cavity (123 [71.9%]), with 108 (63.5%) classified as stage 4 at presentation. On multivariable analysis, a model incorporating individual-level factors with health literacy in addition to community-level factors was most predictive of PORT delay (AOC= 0.78; R2, 0.18)., Conclusions and Relevance: This cohort study provides a more comprehensive assessment of predictors of PORT delays that include health literacy and community-level measures. Predictive models that incorporate multilevel measures outperform models with individual-level factors alone and may guide precise interventions to decrease PORT delay for at-risk patients with HNSCC.

Background: Locoregional failure is a unique and challenging problem in head and neck cancer with controversy surrounding the use of re-irradiation in the treatment. We aimed to evaluate the dosimetry and technical parameters in utilizing a collagen matrix with embedded Cesium-131 (Cs-131) radioactive isotope seeds as it relates to dose distribution and dose to carotid artery., Methods and Materials: Cadaveric feasibility study randomizing Cs-131 strands alone or Cs-131 with collagen matrix to be placed into neck dissection defects. For the dose computation, physicists employed the TG-43 dosimetry calculation algorithm with a point source assumption to compute the dose. Carotid arteries were contoured in MIM-Symphony software and the carotid artery maximum and mean doses were calculated in accordance with TG-43 specifications. Ease of use of collagen matrix tiles on a 7-point Likert scale and mean radiation dose to the carotid artery., Results: Ease of use score was higher in collagen matrix compared to stranded seeds with a mean score of 6.3 +/- 1.2 compared to 4.5 +/- 0.87. Time of implantation was statistically significantly, p = 0.031, lower in the collagen matrix group (M = 5.17 min, SD = 4.62) compared to stranded seeds (M = 15.83 min, SD = 3.24). Mean radiation dose to the carotid artery was 62.8 Gy +/- 9.46 in the collagen matrix group compared to 108.2 Gy +/- 55.6 in the traditional Cs-131 seeds group., Conclusions: We present a feasibility and concept cadaveric study using a collagen matrix with Cesium-131 demonstrating preliminary evidence to support its ease of use, decreased time to implantation, and decreased dose delivered to the carotid artery., (Copyright © 2022 American Brachytherapy Society.
