RESUMEN
INTRODUCTION: Chronic rhinosinusitis (CRS) can be associated with tumors involving the maxillary sinus, but outcomes after undergoing maxillectomy with free flap reconstruction remain unclear. METHODS: A retrospective analysis of medical records was performed to evaluate evidence of CRS in patients who underwent maxillectomy with free flap reconstruction at a single tertiary care academic institution from 2013 through 2020. RESULTS: Eighty-four patients were assessed. Nineteen (22.6%) patients were diagnosed with CRS after surgery, 23 (27.4%) patients were treated for sinus symptoms, and 49 (58.3%) had radiographic evidence of sinus inflammation for more than 6 months. Risk factors for requiring sinus treatment included adjuvant or neoadjuvant chemotherapy (p = 0.002) and pre-operative use of sinus medication (p < 0.001). Radiographic evidence of sinusitis 6 months after surgery is also closely associated with sinusitis treatment (p = 0.051). CONCLUSIONS: CRS may be underdiagnosed in patients undergoing maxillectomy with microvascular reconstruction. Further evaluation into patient sinus disease and symptoms following neoplastic surgery may lead to a higher quality of life in some long-term survivors.
RESUMEN
Introduction: Drug development is systemically inefficient. Research and development costs for novel therapeutics average hundreds of millions to billions of dollars, with the overall likelihood of approval estimated to be as low as 6.7% for oncology drugs. Over half of these failures are due to a lack of drug efficacy. This pervasive and repeated low rate of success exemplifies how preclinical models fail to adequately replicate the complexity and heterogeneity of human cancer. Therefore, new methods of evaluation, early in the development trajectory, are essential both to rule-in and rule-out novel agents with more rigor and speed, but also to spare clinical trial patients from the potentially toxic sequelae (high risk) of testing investigational agents that have a low likelihood of producing a response (low benefit). Methods: The clinical in vivo oncology (CIVO®) platform was designed to change this drug development paradigm. CIVO precisely delivers microdose quantities of up to 8 drugs or combinations directly into patient tumors 4-96 h prior to planned surgical resection. Resected tissue is then analyzed for responses at each site of intratumoral drug exposure. Results: To date, CIVO has been used safely in 6 clinical trials, including 68 subjects, with 5 investigational and 17 approved agents. Resected tissues were analyzed initially using immunohistochemistry and in situ hybridization assays (115 biomarkers). As technology advanced, the platform was paired with spatial biology analysis platforms, to successfully track anti-neoplastic and immune-modulating activity of the injected agents in the intact tumor microenvironment. Discussion: Herein we provide a report of the use of CIVO technology in patients, a depiction of the robust analysis methods enabled by this platform, and a description of the operational and regulatory mechanisms used to deploy this approach in synergistic partnership with pharmaceutical partners. We further detail how use of the CIVO platform is a clinically safe and scientifically precise alternative or complement to preclinical efficacy modeling, with outputs that inform, streamline, and de-risk drug development.
RESUMEN
BACKGROUND: Increased sexual activity is associated with higher human papillomavirus (HPV) rates; however, there is a lack of analysis comparing the sexual history of patients with HPV positive and HPV negative oropharyngeal cancer (OPC). METHODS: In this meta-analysis, PubMed, Scopus, and CINAHL were searched for articles that included patients with OPC and reported information regarding HPV status and either history of oral sex, number of sexual partners, or sexually transmitted infections (STI). RESULTS: A total of 11 studies were included with 3296 patients with OPC. Patients with HPV positive OPC were more likely than patients with HPV negative OPC to report a history of oral sex (92%, 95% CI: 87.0-97.0 vs. 74.5%, 95% CI: 50.6-98.4, p < 0.0001), higher mean number of sexual partners (18.4 partners, 95% CI: 1.5-35.4 vs. 7.2 partners, 95% CI: 1.0-13.4, p < 0.0001), and more frequent history of STI (23.7%, 95% CI: 18.4-29.0 vs. 8.8%, 95% CI: 4.7-12.8, p = 0.0001). CONCLUSIONS: Compared to patients with HPV negative OPC, our analysis shows a larger proportion of patients with HPV positive OPC had participated in oral sex, had a higher number of sexual partners, and had a higher proportion of STI history.
RESUMEN
Purpose: The purpose of this study was to evaluate the feasibility and safety of dose-escalated proton beam therapy for treating chordomas and chondrosarcomas of the skull base and spine. Methods: A prospective cohort of 54 patients (42 with chordomas and 12 with chondrosarcomas) was enrolled between 2010 and 2018. The primary endpoints were feasibility and <20% rate of acute grade ≥3 toxicity, and secondary endpoints included cancer-specific outcomes and toxicities. Patients were followed with magnetic resonance imaging or computed tomography at 3-month intervals. Proton beam therapy was delivered with doses up to 79.2 Gy using protons only, combination protons/intensity modulated radiation therapy (IMRT), or IMRT only. Results: Feasibility endpoints were met, with only 2 out of 54 patient radiation therapy plans failing to meet dosimetric constraints with protons, and 4 out of 54 experiencing a delay or treatment break >5 days, none for toxicities related to treatment. There were no grade 4 acute toxicities and 1 grade 3 acute toxicity (sensory neuropathy). The only 2 grade 3 late toxicities recorded, osteoradionecrosis and intranasal carotid blowout (mild and not emergently treated), occurred in a single patient. We report overall survival as 83% at 5 years, with local failure-free survival and progression-free survival rates of 72% and 68%, respectively. Five patients developed distant disease, and among the 9/54 patients who died, 4 deaths were not attributed to treatment or recurrence. Conclusions: Our findings suggest that high-dose proton therapy alone or in combination with IMRT is a safe and effective treatment option for chordomas and chondrosarcomas of the skull base and spine.
RESUMEN
OBJECTIVE: To assess the incidence of vascular events in patients with head and neck cancer. REVIEW METHODS: Primary studies identified through April 2023. Meta-analysis was performed. RESULTS: There were 146 studies included in the systematic review. Rates of events were collected in the overall group, those with chemoprophylaxis, and those that underwent surgery, radiation, or chemotherapy. Of 1 184 160 patients, 4.3% had a vascular event. Radiation therapy had highest risk of overall events and stroke when compared to surgery and chemotherapy. Chemotherapy had a higher risk of stroke and overall events when compared to surgery. CONCLUSIONS: Vascular events occur in 4%-5% of patients with head and neck cancer. Our data does not support the use of routine anticoagulation. Patients undergoing radiation therapy had the highest frequency of events.

INTRODUCTION: Management of the neck in oral cavity squamous cell carcinoma (OCSCC) is essential to oncologic control and survival. The rates of lymph node metastasis (LNM) vary based on oral cavity tumor site and stage and influence treatment decisions. The aim of this paper was to describe clinical LNM for different tumor subsites and stages of surgically managed OCSCC. METHODS: We conducted a retrospective analysis of 25,846 surgically managed OCSCC patients from the National Cancer Database (NCDB) stratified by tumor subsite and clinical T-stage. For cN + patients, rates of pathologic LNM and absence of pathologic LNM were determined. For cN0 patients, outcomes included the rates of elective neck dissection (END) and occult LNM and predictors of occult LNM determined by a multivariable logistic regression model. RESULTS: A total of 25,846 patients (59.1% male, mean age 61.9 years) met inclusion criteria with primary tumor sites including oral tongue (50.8%), floor of mouth (21.2%), lower alveolus (7.6%), buccal mucosa (6.7%), retromolar area (4.9%), upper alveolus (3.6%), hard palate (2.7%), and mucosal lip (2.5%). Among all sites, clinical N+ rates increased with T-stage (8.9% T1, 28.0% T2, 51.6% T3, 52.5% T4); these trends were preserved across subsites. Among patients with cN + disease, the overall rate of concordant positive pathologic LNM was 80.1% and the rate of discordant negative pathologic LNM was 19.6%, which varied based on tumor site and stage. In the overall cohort of cN0 patients, 59.9% received END, and the percentage of patients receiving END increased with higher tumor stage. Occult LNM among those cN0 was found in 25.1% of END cases, with the highest rates in retromolar (28.8%) and oral tongue (27.5%) tumors. Multivariable regression demonstrated significantly increased rates of occult LNM for higher T stage (T2 OR: 2.1 [1.9-2.4]; T3 OR: 3.0 [2.5-3.7]; T4 OR: 2.7 [2.2-3.2]), positive margins (OR: 1.4 [1.2-1.7]), and positive lymphovascular invasion (OR: 5.1 [4.4-5.8]). CONCLUSIONS: Management of the neck in OCSCC should be tailored based on primary tumor factors and considered for early-stage tumors.

Importance: Olfactory dysfunction (OD) is increasingly recognized as a robust marker of frailty and mortality. Despite broad recognition of frailty as a critical component of head and neck cancer (HNC) care, there is no standardized frailty assessment. Objective: To assess the prevalence of OD and its association with frailty and postoperative outcomes in HNC. Design, Setting, and Participants: In this prospective cohort study with enrollment between February 17, 2021, to September 29, 2021, at a tertiary academic medical center, 85 eligible adult patients with primary, treatment-naive HNC of mucosal or cutaneous origin were included. Patients with a history of COVID-19, neurocognitive, or primary smell/taste disorders were excluded. Exposures: Prospective olfactory assessments (self-reported, visual analog scale [VAS] and psychophysical, University of Pennsylvania Smell Identification Test [UPSIT]) with concurrent frailty assessment (Risk Analysis Index [RAI]) were used. Olfactory-specific quality of life (QOL) was examined with brief Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS). Main Outcome(s) and Measure(s): The primary outcome was the prevalence of OD as assessed by VAS (0-10, no to normal smell) and UPSIT (0-40, higher scores reflect better olfaction) and its association with frailty (RAI, 0-81, higher scores indicate greater frailty). For surgical patients, secondary outcomes were associations between OD and postoperative length of stay (LOS), 30-day postoperative outcomes, and QOD-NS (0-21, higher scores indicate worse QOL). Results: Among 51 patients with HNC (mean [SD] age, 63 [10] years; 39 [77%] male participants; 41 [80%] White participants), 24 (47%) were frail, and 4 (8%) were very frail. Despite median (IQR) self-reported olfaction by VAS of 9 (8-10), 30 (59%) patients demonstrated measured OD with psychophysical testing. No meaningful association was found between self-reported and psychophysical testing (Hodges-Lehmann, <0.001; 95% CI, -2 to 1); a total of 46 (90%) patients did not report decreased olfaction-specific QOL. Median UPSIT scores were lower in frail patients (Hodges-Lehmann, 6; 95% CI, 2-12). Multivariate modeling demonstrated severe microsmia/anosmia was associated with 1.75 (95% CI, 1.09-2.80) times odds of being frail/very frail and approximately 3 days increased LOS (ß, 2.96; 95% CI, 0.29-5.62). Conclusions and Relevance: Although patients with HNC are unaware of olfactory changes, OD is common and may serve as a bellwether of frailty. In this prospective cohort study, a dose-dependent association was demonstrated between increasing degrees of OD and frailty, and the potential utility of olfaction was highlighted as a touchstone in the assessment of HNC frailty.

BACKGROUND: Management of the neck in laryngeal squamous cell carcinoma (LSCC) is essential to oncologic control and survival. We aim to describe patterns and rates of clinical/pathologic lymph node disease, elective neck dissection (END), and occult lymph node metastasis (LNM) in patients with surgically-managed LSCC. METHODS: Retrospective cohort study of patients in the National Cancer Database (NCDB) diagnosed with LSCC between January 2004 and December 2016 who underwent primary surgery. RESULTS: Seven thousand eight hundred and seventy-six patients met inclusion criteria. For cN0 patients, the rates of END and occult LNM both increased with tumor stage and were highest for supraglottic tumors. Predictors of occult LNM included supraglottic site, pathologic T3 and T4 stage, positive margins, and presence of lymphovascular invasion (p < 0.05). CONCLUSIONS: The propensity for cervical LNM in surgically-managed LSCC varies based on primary tumor site and stage, and a variety of disease factors increase risk of occult LNM.

Giant cell tumor of the soft tissue (GCTST) is a neoplasm with low malignant potential and typically affects the trunk and extremities. Herein, we present a case of a palpable right neck mass diagnosed as a GCTST of the carotid sheath in a 38-year-old woman. A review of the imaging characteristics as well as of the differential diagnoses of primary neoplasms of the carotid space is presented.
RESUMEN
Objectives Although adjuvant radiotherapy may be indicated in patients with sinonasal squamous cell carcinoma (SNSCC) following primary surgery, some patients choose to forgo recommended postoperative radiation therapy (PORT). This study aimed to elucidate factors associated with patient refusal of recommended PORT in SNSCC and examine overall survival. Methods Retrospective analysis of patients with SNSCC treated with primary surgery from the National Cancer Database diagnosed between 2004 and 2016. A multivariable logistic regression model was created to determine the association between clinical or demographic covariates and likelihood of PORT refusal. Unadjusted Kaplan-Meier estimates, log-rank tests, and a multivariable Cox proportional hazard model were used to assess overall survival. Results A total of 2,231 patients were included in the final analysis, of which 1,456 (65.3%) were males and 73 (3.3%) refused recommended PORT. Patients older than 74 years old were more likely to refuse PORT than those younger than 54 (odds ratio [OR] 3.43, 95% confidence interval [CI]: 1.84-6.62). Median survival among the entire cohort, those who received recommended PORT, and those who refused PORT was 83.0 months (95% CI: 74.6-97.1), 83.0 months (95% CI: 74.9-98.2), and 63.6 months (95% CI: 37.3-101.4), respectively. Refusal of PORT was not associated with overall survival (hazard ratio: 0.99, 95% CI: 0.69-1.42). Conclusions PORT refusal in patients with SNSCC is rare and was found to be associated with several patient factors. The decision to forgo PORT is not independently associated with overall survival in this cohort. Further study is required to determine the clinical implications of these findings as the treatment decisions are complex.
RESUMEN
In patients receiving treatment for head and neck cancer (HNC), there is a correlation between quality of life (QoL) scores and treatment outcomes. Higher QoL scores have been associated with improved survival. Despite this, the assessment of QoL in clinical trials varies considerably. Three databases (Scopus, PubMed, and Cinahl) were queried for articles published in English between 2006 and 2022. Two reviewers (SRS and ANT) performed study screening, data extraction, and risk of bias assessment. The authors identified 21 articles that met the inclusion criteria. A total of 5961 patients were evaluated. QoL was reported as average scores for specific variables across five different surveys in 12 included articles. Supplemental QoL data were available in 10 included studies. Critical appraisal of studies indicated a high risk of bias due to the inclusion of trials. There is no standard method for reporting QoL data in clinical trials for HNC patients undergoing treatment with anti-EGFR inhibitors. Future clinical trials should standardize their method for assessing and reporting quality-of-life data to increase patient-centered care and refine treatment choices to optimize survival.
RESUMEN
OBJECTIVE: To determine whether gender differences exist in the training history, practice patterns, and home lives of surgeons who perform microvascular reconstruction of the head and neck. STUDY DESIGN: Cross-sectional survey. SETTING: Medical facilities that employ surgeons who practice head and neck microvascular reconstruction in the United States. METHODS: A survey was created using the Research Electronic Data Capture Framework and was distributed via email to microvascular reconstructive surgeons. Descriptive statistics were performed using Stata software. RESULTS: No significant differences were found in training or current practice patterns between microvascular surgeons who identify as men versus those who identify as women. Women had fewer children (p = .020) and were more likely to be childless (p = .002). Whereas men were more likely to report a spouse/partner as primary caretaker, women were more likely to hire a professional caretaker or cite themselves as a primary caretaker (p < .001). Women were more likely to have finished residency (p = .015) and fellowship (p = .014) more recently and to practice in the Southeast (p = .006). Of the microvascular surgeons who reported practice setting switches, men more commonly changed positions for career advancement, whereas women were more likely to switch due to burnout (p = .002). CONCLUSION: This study found no gender-based differences in training or practice patterns. However, significant differences were identified in childbearing, family structure, geographic practice location, and motives for switching practice.

Background: Head and neck free flap survival relies on adequate tissue perfusion from the external carotid artery (ECA), and vessel length is inversely proportional to blood flow rate. Objective: Investigate whether distance from the ECA (as a proxy for pedicle vessel length) predicts flap survival or complications. Methods: Retrospective review of free flaps performed at three academic centers from 9/2006 to 8/2021. Flaps were categorized by distance from the ECA: orbit and above (zone 1), maxilla to parotid (zone 2), and mandible and below (zone 3). Secondary analysis assessed flap outcomes stratified by average historical pedicle length. Results: A total of 2,369 flaps were identified in zones 1 (n = 109), 2 (n = 1878), and 3 (n = 382). Rates of flap failure (4.9%) and perioperative complications (36.3%) did not differ by zone or pedicle length. Zone 3 flaps, most commonly located in the larynx and hypopharynx, had significantly higher rates of fistula and infection. Conversely, 30-day readmission rates were significantly lower in patients with zone 2 flaps (p < 0.001). Rates of all other complications did not differ significantly between zones. Conclusions: Proximity to mucosal anatomic sites was a more powerful predictor of free flap viability than pedicle length or ECA proximity.

Malpractice claims involving robot-assisted surgical procedures have increased more than 250% in the past 7 years compared to the seven years prior. We examined robotic surgery malpractice claims to identify trends in claimed liabilities, describe legal outcomes, and determine strategies to minimize future litigation. The Westlaw legal database was queried retrospectively for U.S. state and federal trials regarding robot-assisted surgical procedures from 2006 to 2013 and 2014 to 2021. Data abstracted from verdict reports included year, state, court type, defendant specialty, procedure performed, claimed injuries and liabilities, verdict, and damage amount awarded. Sixty-one cases across 25 states were identified, 16 cases between 2006 and 2013, and 45 from 2014 to 2021. Among those 45 cases, defendant verdicts predominated (n = 35, 77.8%), with only four plaintiff verdicts (8.9%) and six settlements (13.3%). Overall, 169 liabilities were claimed, most commonly negligent surgery (82.2%), misdiagnosis/failure to diagnose (46.7%), delayed treatment (35.6%), and lack of informed consent (31.1%). Thirteen cases resulted in indemnity payments (mean = $1,251,274), with damages ranging from $10,087 (infection and retained foreign body) to $5,008,922 (patient death). Hysterectomy (n = 19, 42.2%) was the most commonly litigated surgery, followed by prostatectomy (n = 5) and hernia repair (n = 4). The most litigated specialties were obstetrics/gynecology (48.9%), general surgery (28.9%), and urology (15.6%). Malpractice litigation in robot-assisted surgery is infrequent. As robotic procedures become more commonplace, surgeons must keep common liabilities in mind, as there are valuable and actionable lessons to be learned from these cases. Malpractice reform, continuing medical education activities, and improved informed consent protocols may help minimize future litigation.

OBJECTIVE: To identify key recommendations for maximizing the efficiency and efficacy of perioperative care in transsphenoidal pituitary surgery. METHODS: The authors performed a comprehensive literature search of Enhanced Recovery After Surgery protocols implemented for patients undergoing transsphenoidal adenomectomy (TSA); individual recommendations were abstracted, and the evidence base thoroughly reviewed. RESULTS: The authors identified 19 individual recommendations pertinent to the care of patients undergoing TSA, which were subdivided into preoperative (n=6), intraoperative (n=6), and postoperative (n=7) interventions. Key factors recommended for minimizing length of stay, preventing readmission, and improving patient outcomes included comprehensive patient education, multidisciplinary evaluation, avoidance of routine lumbar drain placement and nasal packing, and rigorous postoperative monitoring of pituitary function and salt-water imbalances. The overall level of evidence for 7/19 (37%) implemented recommendations was found to be low, suggesting a need for continued research in this patient population. CONCLUSION: Several key interventions should be considered in the development of Enhanced Recovery After Surgery protocols for TSA, which may aid in further decreasing length of stay and promoting positive patient outcomes.

OBJECTIVES: To determine whether 2 different methods of post-operative head and neck free flap monitoring affect flap failure and complication rates. METHODS: A retrospective chart review of 803 free flaps performed for head and neck reconstruction by the same microvascular surgeon between July 2013 and July 2020 at 2 separate hospitals within the same healthcare system. Four-hundred ten free flaps (51%) were performed at Hospital A, a medical center where flap checks were performed at frequent, scheduled intervals by in-house resident physicians and nurses; 393 free flaps (49%) were performed at Hospital B, a medical center where flap checks were performed regularly by nursing staff with resident physician evaluation as needed. Total free flap failure, partial free flap failure, and complications (consisting of wound infection, fistula, and reoperation within 1 month) were assessed. RESULTS: There were no significant differences between Hospitals A and B when comparing rates of total free flap failure, partial free flap failure, complication, or re-operation (P = .27, P = .66, P = .65, P = .29, respectively). There were no significant differences in urgent re-operation rates for flap compromise secondary to thrombosis and hematoma (P = .54). CONCLUSIONS: In our series, free flap outcomes did not vary based on the degree of flap monitoring by resident physicians. This data supports the ability of a high-volume, well-trained, nursing-led flap monitoring program to detect flap compromise in an efficient fashion while limiting resident physician obligations in the age of resident duty hour restrictions.

Objective: The reconstruction of large scalp defects poses both functional and cosmetic challenges. While free tissue transfer remains the standard for defects larger than 30 cm2, prolonged anesthesia and postoperative complications remain significant limitations. The purpose of this study is to evaluate the use of O-Z flaps for the reconstruction of large scalp defects and to describe the techniques employed. Methods: This is a retrospective analysis of ten patients who underwent reconstructive surgery using an O-Z flap approach for large scalp defects between July 2017 and June 2019. The parameters included in this study were patient demographics, tumor characteristics, and postoperative management, collected for at least a year after surgery. Results: In this cohort, the mean age was 76.1 years and 90% were male. All patients were treated for neoplastic skin lesions, with 70% located on the vertex and 30% located on the temporoparietal region. The mean size of defect was 52.0 cm2 (range: 38.6 to 63.8 cm2). The maximum hospital stay was two days, and no patients were readmitted within 30 days of surgery. There were no cases of wound infection or flap necrosis. All patients reported pain control with acetaminophen and ibuprofen. Four patients received adjuvant radiation, and there was no delay to receiving treatment following surgery. Conclusions: The O-Z flap is a reliable alternative for the reconstruction of non-irradiated scalp defects in the vertex and temporoparietal regions up to 63 cm2. This technique provides advantages for patients, including hairline preservation, shorter hospital stays, and decreased postoperative complications.
RESUMEN
The objective of our paper was to answer the following question: how do patients with HPV-related oropharyngeal squamous cell carcinoma OPSCC (Population) enrolled in clinical trials (Intervention), compared with national database reports of HPV-associated OPSCC patients (Comparison), present demographically (Outcome)? We conducted a systematic review and meta-analysis of studies pertaining to clinical trials of HPV-associated OPSCC and participant demographics in the United States. PubMed, Scopus, CINAHL, and the Cochrane Library were searched from inception to 2 February 2022. Studies of overlapping participant cohorts and/or studies conducted outside of the United States were excluded. Primary outcomes were patient age, sex, and race. Secondary outcomes were smoking history, alcohol history, history of prior cancer, and tumor origin site. Meta-analysis of single means (mean, N for each study, and standard deviation) for age, pack years, and smoking years was performed. Pooled prevalence rates of gender, race, alcohol history, tobacco history, and tumor origin site were expressed as a percentage, with 95% confidence intervals. Meta-analysis found patients to be predominately non-smoking white males, with tumors originating from the tonsil. Our findings reflected the demographics reported by the National Cancer Database (NCDB) for HPV-associated OPSCC. This indicates that HPV-associated OPSCC patients are appropriately represented in clinical trial demographics.
RESUMEN
OBJECTIVE: To assess the feasibility and effectiveness of indocyanine green (ICG) for image-guided resection of head and neck cancer (HNC). DATA SOURCES: PubMed, Embase, and Scopus databases. REVIEW METHODS: Searches were conducted from database inception to February 2022. Patient and study characteristics, imaging parameters, and imaging efficacy data were extracted from each study. RESULTS: Nine studies met inclusion criteria, representing 103 head and neck tumors. Weighted mean ICG dose and imaging time were 1.27 mg/kg and 11.77 h, respectively. Among the five studies that provided quantitative metrics of imaging efficacy, average ICG tumor-to-background ratio (TBR) was 1.56 and weighted mean ONM-100 TBR was 3.64. Pooled sensitivity and specificity across the five studies were 91.7 % and 71.9 %, respectively. CONCLUSION: FGS with ICG may facilitate real-time tumor-margin delineation to improve margin clearance rates and progression-free survival. Future studies with validated, quantitative metrics of imaging success are necessary to further evaluate the prognostic benefit of these techniques.
