African Head and Neck Society Clinical Practice guidelines for thyroid nodules and cancer in developing countries and limited resource settings

BACKGROUND

International thyroid nodule and cancer management guidelines generally fail to take into account potential limitations in diagnostic and treatment resources.

METHODS

Thyroid cancer specialists from the African Head and Neck Society and American Head & Neck Society Endocrine Section developed guidelines for diagnosis and management of thyroid nodules and cancer in low resource settings. Recommendations were based on literature review and expert opinion, with level of evidence defined.

RESULTS

Using the ADAPTE process, diagnostic and treatment algorithms were adapted from the National Comprehensive Cancer Network (NCCN). Low resource settings were simulated by systematically removing elements such as availability of laboratory testing, hormone replacement, imaging, and cytopathology from NCCN guidelines.

CONCLUSIONS

Successful management of thyroid nodules and cancer in low resource settings requires adaptation of treatment methodologies. These guidelines define specific scenarios where either more or less aggressive intervention for thyroid pathology may be advisable based on limited available resources.

Impact of Sarcopenia on Outcomes of Autologous Head and Neck Free Tissue Reconstruction

BACKGROUND

 Sarcopenia has been implicated as a positive predictor of postsurgical complications. Its role in head and neck (H&N) free flap reconstruction has yet to be examined. Our study aimed to determine the clinical impact of sarcopenia on postoperative outcomes in patients receiving autologous free tissue reconstruction for H&N cancer (HNC).

METHODS

 A retrospective case-control study was conducted at our tertiary referral center. Patients with HNC who received oncologic resection followed by autologous free tissue reconstruction were included. Preoperative abdominal computed tomography (CT) imaging was analyzed at the third lumbar vertebra (L3) to calculate skeletal muscle cross-sectional area (CSA, cm²). Skeletal muscle index (SMI, cm²/m²) was calculated by normalizing CSA to patient height. Sarcopenia at L3 was defined as SMI ≤ 41.6 cm²/m² for males and ≤ 32.0 cm²/m² for females. Data analyses were performed to compare postoperative outcomes.

RESULTS

 Of the 168 patients who met inclusion criteria, 47 patients (28.0%) were determined to have preoperative sarcopenia. The sarcopenic group was older (63 vs. 58 years, p = 0.017), had lower body mass index (BMI; 21.2 vs. 27.2, p < 0.001), had greater incidence of alcohol abuse (55.3 vs. 23.1%, OR = 4.11, p < 0.001). Intraoperatively, sarcopenic patients were found to have greater rates of blood transfusions (63.8 vs. 29.8%, p < 0.001). Postoperatively, sarcopenic patients had higher rates of pneumonia (p < 0.01), venous thromboembolism (p < 0.01), prolonged ventilation (p < 0.01), delirium (p < 0.01), fistula (p < 0.05), wound disruption (p < 0.05), and longer intensive care unit stays (p < 0.05). Sarcopenic patients were ultimately found to have higher overall rates of general postoperative complications (p < 0.001) and flap-specific complications (p < 0.01).

CONCLUSION

 Sarcopenia was found to be a predictor of postoperative complications in H&N free flap reconstruction, signifying its value as a negative prognostic factor in surgical outcomes. This study reflects level of evidence IV.

Association of Adjuvant Radiation Therapy With Survival in Patients With Advanced Cutaneous Squamous Cell Carcinoma of the Head and Neck

Importance

Cutaneous squamous cell carcinoma (CSCC) is one of the most common malignant tumors worldwide. There is conflicting evidence regarding the indications for and benefits of adjuvant radiation therapy for advanced CSCC tumors of the head and neck.

Objective

To assess indications for adjuvant radiation therapy in patients with CSCC.

Design, Setting, and Participants

Retrospective analysis of 349 patients with head and neck CSCC treated with primary resection with or without adjuvant radiation therapy at 2 tertiary referral centers from January 1, 2008, to June 30, 2016.

Main Outcomes and Measures

Data were compared between treatment groups with a χ2 analysis. Disease-free survival (DFS) and overall survival (OS) were analyzed using a Kaplan-Meier survival analysis with log-rank test and a Cox proportional hazards multivariate regression.

Results

A total of 349 patients had tumors that met the inclusion criteria (mean [SD] age, 70 [12] years; age range, 32-94 years; 302 [86.5%] male), and 191 (54.7%) received adjuvant radiation therapy. The 5-year Kaplan-Meier estimates were 59.4% for DFS and 47.4% for OS. Patients with larger, regionally metastatic, poorly differentiated tumors with perineural invasion (PNI) and younger immunosuppressed patients were more likely to receive adjuvant radiation therapy. On Cox proportional hazards multivariate regression, patients with periorbital tumors (hazard ratio [HR], 2.48; 95% CI, 1.00-6.16), PNI (HR, 1.90; 95% CI, 1.12-3.19), or N2 or greater nodal disease (HR, 2.16; 95% CI, 1.13-4.16) had lower DFS. Immunosuppressed patients (HR, 2.17; 95% CI, 1.12-4.17) and those with N2 or greater nodal disease (HR, 2.43; 95% CI, 1.42-4.17) had lower OS. Adjuvant radiation therapy was associated with improved OS for the entire cohort (HR, 0.59; 95% CI, 0.38-0.90). In a subset analysis of tumors with PNI, adjuvant radiation therapy was associated with improved DFS (HR, 0.47; 95% CI, 0.23-0.93) and OS (HR, 0.44; 95% CI, 0.24-0.86). Adjuvant radiation therapy was also associated with improved DFS (HR, 0.36; 95% CI, 0.15-0.84) and OS (HR, 0.30; 95% CI, 0.15-0.61) in patients with regional disease.

Conclusions and Relevance

Among patients with advanced CSCC, receipt of adjuvant radiation therapy was associated with improved survival in those with PNI and regional disease.

Fluorescence lifetime imaging for intraoperative cancer delineation in transoral robotic surgery

This study evaluates the potential for fluorescence lifetime imaging (FLIm) to enhance intraoperative decisionmaking during robotic-assisted surgery of oropharyngeal cancer. Using a custom built FLIm instrument integrated with the da Vinci robotic surgical platform, we first demonstrate that cancer in epithelial tissue diagnosed by histopathology can be differentiated from surrounding healthy epithelial tissue imaged in vivo prior to cancer resection and ex vivo on the excised specimen. Second, we study the fluorescence properties of tissue imaged in vivo at surgical resection margins (tumor bed). Fluorescence lifetimes and spectral intensity ratios were calculated for three spectral channels, producing a set of six FLIm parameters. Current results from 10 patients undergoing TORS procedures demonstrate that healthy epithelium can be resolved from cancer (P < .001) for at least one FLIm parameter. We also showed that a multiparameter linear discriminant analysis approach provides superior discrimination to individual FLIm parameters for tissue imaged both in vivo and ex vivo. Overall, this study highlights the potential for FLIm to be developed into a diagnostic tool for clinical cancer applications of the oropharynx. This technique could help to circumvent the issues posed by the lack of tactile feedback associated with robotic surgical platforms to better enable cancer delineation.

Pathological margins and advanced cutaneous squamous cell carcinoma of the head and neck

Objective

The recommended treatment for cutaneous squamous cell cancer (CuSCC) of the head and neck is Mohs surgical excision or wide local excision. Excision is recommended to a gross surgical margin of 4–6 mm however this is based on limited evidence and specify a goal histologic margin. The objective of this study was therefore to examine the reported histological margin distance following WLE of advanced CuSCC and its association with recurrence and survival.

Study design

Retrospective database review.

Setting

All patients included received treatment at UC Davis Department of Otolaryngology-Head and Neck Surgery and/or Radiation Oncology in Sacramento, California.

Subjects and methods

The patients included were treated for advanced CuSCC with primary surgery with or without adjuvant therapy. Kaplan Meier survival curves with log rank analysis were then performed to compare 5-year recurrence free survival, and disease-specific survival for patients with different margin distances.

Results

Total number of subjects was 92. The overall 5-year DSS and RFS was 68.8 and 51.0% respectively. When the pathological margin distance was ≥5 mm, 5-year disease specific survival was improved when compared to margin distance less than 5 mm (94.7 vs 60.7 p = 0.034).

Conclusion

The findings of this study suggest that a histologic margin of at least 5 mm may increase survival in advanced head and neck CuSCC patients.

Malnutrition evaluation in head and neck cancer patients: Practice patterns among otolaryngologists and radiation oncologists

BACKGROUND

Physician practice patterns regarding diagnosis and management of malnutrition in the head and neck cancer patient population are not well studied.

METHODS

A 17-question survey was distributed to 1392 members of the American Head and Neck Society (AHNS). The impact of hospital type, fellowship training, experience, and specialty was assessed.

RESULTS

Among AHNS members, there were 124 total respondents (9% response rate), including both otolaryngologists and radiation oncologists. Respondents strongly agreed (90%) that malnutrition negatively impacts patient outcomes. The majority (63%) felt comfortable screening for malnutrition, but 13% reported no routine assessment of malnutrition; 57% were unfamiliar with relevant guidelines. Barriers to screening included lack of familiarity with screening tools/guidelines, lack of time, and lack of access to dietitian.

CONCLUSION

Although there was a strong consensus among respondents that the identification and management of malnutrition among head and neck cancer patients is critical, familiarity with relevant guidelines was poor.

MET Genomic Alterations in Head and Neck Squamous Cell Carcinoma (HNSCC): Rapid Response to Crizotinib in a Patient with HNSCC with a Novel MET R1004G Mutation

Identification of effective targeted therapies for recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) remains an unmet medical need. A patient with platinum-refractory recurrent oral cavity HNSCC underwent comprehensive genomic profiling (CGP) that identified an activating MET mutation (R1004). The patient was treated with the oral MET tyrosine kinase inhibitor crizotinib with rapid response to treatment.Based on this index case, we determined the frequency of MET alterations in 1,637 HNSCC samples, which had been analyzed with hybrid capture-based CGP performed in the routine course of clinical care. The specimens were sequenced to a median depth of >500× for all coding exons from 182 (version 1, n = 24), 236 (version 2, n = 326), or 315 (version 3, n = 1,287) cancer-related genes, plus select introns from 14 (version 1), 19 (version 2), or 28 (version 3) genes frequently rearranged in cancer. We identified 13 HNSCC cases (0.79%) with MET alterations (4 point mutation events and 9 focal amplification events). MET-mutant or amplified tumors represent a small but potentially actionable molecular subset of HNSCC. KEY POINTS: This case report is believed to be the first reported pan-cancer case of a patient harboring a MET mutation at R1004 demonstrating a clinical response to crizotinib, in addition to the first documented case of head and neck squamous cell carcinoma (HNSCC) with any MET alteration responding to crizotinib.The positive response to MET inhibition in this patient highlights the significance of comprehensive genomic profiling in advanced metastatic HNSCC to identify actionable targetable molecular alterations as current treatment options are limited.

HPV-related oropharyngeal cancer: a review on burden of the disease and opportunities for prevention and early detection

The incidence of oropharyngeal cancer (OPC) related to infection with human papillomavirus (HPV) is rising, making it now the most common HPV-related malignancy in the United States. These tumors present differently than traditional mucosal head and neck cancers, and those affected often lack classic risk factors such as tobacco and alcohol use. Currently, there are no approved approaches for prevention and early detection of disease, thus leading many patients to present with advanced cancers requiring intense surgical or nonsurgical therapies resulting in significant side effects and cost to the health-care system. In this review, we outline the evolving epidemiology of HPV-related OPC. We also summarize the available evidence corresponding to HPV-related OPC prevention, including efficacy and safety of the HPV vaccine in preventing oral HPV infections. Finally, we describe emerging techniques for identifying and screening those who may be at high risk for developing these tumors.

Oncologic outcomes after surgery for locally aggressive basal cell carcinoma of the head and neck

OBJECTIVE

Although basal cell carcinoma (BCC) is the most common skin cancer, locally aggressive BCC of the head and neck is rare and not well studied.

STUDY DESIGN

Retrospective review of patients who underwent primary surgical resection of locally aggressive head and neck BCC at a single tertiary academic center.

RESULTS

Eighty-seven patients with 98 tumors demonstrated a 5-year Kaplan-Meier estimated recurrence-free survival of 64.5%, overall survival of 83.3%, and disease-specific survival of 98.3%. Intraoperative positive frozen section margin was a strong independent predictor of local recurrence (hazard ratio 6.88, P = 0.038) and was more likely to occur in tumors previously treated with radiation (odds ratio 6.47 = 0.05).

CONCLUSION

Locally aggressive BCCs of the head and neck have high rates of local recurrence but low disease-specific mortality when treated with primary surgery and selected use of adjuvant therapy. Intraoperative positive frozen section margin is a strong independent predictor of local recurrence and is more likely in tumors that were previously treated with radiation therapy.

AHNS Series - Do you know your guidelines?: Assessment and management of malnutrition in patients with head and neck cancer: Review of the NCCN Clinical Practice Guidelines In Oncology (NCCN Guidelines)

This article is a part of the "Do you know your guidelines" series by the Education Committee of the American Head and Neck Society. The aim is to summarize the core principles outlined by the NCCN Clinical Practice Guidelines In Oncology (NCCN Guidelines^® ) on management of malnutrition in patients with head and neck cancer. We outline the current recommendations from the National Comprehensive Cancer Network^® (NCCN^® ) for the screening and management of malnutrition, including indications for nutritional supplementation and placement of a nasogastric or gastrostomy tube. We also include a brief review of the available literature on additional screening tools, alternative guidelines, as well as an update on the emerging data surrounding the use of immune-enhancing nutrition.

AHNS series: Do you know your guidelines? Diagnosis and management of salivary gland tumors

This article is the next installment of the series "Do you know your guidelines" presented by the Education Committee of the American Head and Neck Society. Guidelines for the workup and management of tumors of the major and minor salivary glands are reviewed.

Approximating Cellular Densities from High-Resolution Neuroanatomical Imaging Data

Characterizing the cellular architecture (cytoar-chitecture) of tissues in the nervous system is critical for modeling disease progression, defining boundaries between brain regions, and informing models of neural information processing. Extracting this information from anatomical data requires the expertise of trained neuroanatomists, and is a challenging task for inexperienced analysts. To address this need, we present an unbiased, automated method to estimate cellular density of retinal and neocortical datasets. Our approach leverages the fact that within retinal and neurocortical datasets, cells are organized into "layers" of constant density to approximate cytoarchitecture with a small number of known basis elements. We introduce methods for patch extraction, cell detection, and sparse approximation of inhomogeneous Poisson processes to differentiate changes in cellular densities and detect layers. Our results demonstrate the feasibility of using automation to reveal the cytoarchitecture of large-scale biological samples.

Factors Associated with Recurrence and Regional Adenopathy for Head and Neck Cutaneous Squamous Cell Carcinoma

Objective

Cutaneous squamous cell carcinoma (CSCC) is one of the most common malignancies worldwide. With advanced CSCC of the head and neck, there is conflicting evidence on what constitutes high-risk disease. Our objective is to evaluate which factors are predictive of recurrence and nodal spread and survival.

Study Design

Case series with chart review.

Setting

Tertiary academic institution.

Subjects and Methods

Patients with advanced head and neck CSCC treated with primary resection identified by chart review.

Results

A total of 212 patients met inclusion criteria, with a mean age of 70.4 years; 87.3% were men. Mean tumor diameter was 3.65 cm, with an average depth of invasion of 1.38 cm. The mean follow-up time was 35 months (median, 21.5), and over that period 67 recurrences were recorded, 49 of which were local. The 5-year Kaplan-Meier estimate of disease-free survival for the cohort was 53.2%. On Cox multivariate analysis, recurrent disease, perineural invasion (PNI), and poorly differentiated histology were independent predictors of recurrence. On multinomial logistic regression, patients with primary tumors on the ear, cheek, temple, or lip, as well as those with PNI, were more likely to present with nodal metastasis.

Conclusion

For advanced CSCCs of the head and neck, patients with recurrent disease, PNI, and poorly differentiated tumors are at highest risk for local recurrence. Patients with tumors or the ear, cheek, temple, or lip, as well as those with PNI, are at increased risk of harboring nodal disease.

Reirradiation of Recurrent and Second Primary Head and Neck Cancer With Proton Therapy

PURPOSE

To report the clinical outcomes of head and neck reirradiation with proton therapy.

METHODS AND MATERIALS

From 2004 to 2014, 61 patients received curative-intent proton reirradiation, primarily for disease involving skull base structures, at a median of 23 months from the most recent previous course of radiation. Most had squamous cell (52.5%) or adenoid cystic (16.4%) carcinoma. Salvage surgery before reirradiation was undertaken in 47.5%. Gross residual disease was present in 70.5%. For patients with microscopic residual disease, the median dose of reirradiation was 66 Gy (relative biological effectiveness), and for gross disease was 70.2 Gy (relative biological effectiveness). Concurrent chemotherapy was given in 27.9%.

RESULTS

The median follow-up time was 15.2 months and was 28.7 months for patients remaining alive. The 2-year overall survival estimate was 32.7%, and the median overall survival was 16.5 months. The 2-year cumulative incidence of local failure with death as a competing risk was 19.7%; regional nodal failure, 3.3%; and distant metastases, 38.3%. On multivariable analysis, Karnofsky performance status ≤70%, the presence of a gastrostomy tube before reirradiation, and an increasing number of previous courses of radiation therapy were associated with a greater hazard ratio for death. A cutaneous primary tumor, gross residual disease, increasing gross tumor volume, and a lower radiation dose were associated with a greater hazard ratio for local failure. Grade ≥3 toxicities were seen in 14.7% acutely and 24.6% in the late setting, including 3 treatment-related deaths.

CONCLUSIONS

Reirradiation with proton therapy, with or without chemotherapy, provided reasonable locoregional disease control, toxicity profiles, and survival outcomes for an advanced-stage and heavily pretreated population. Additional data are needed to identify which patients are most likely to benefit from aggressive efforts to achieve local disease control and to evaluate the potential benefit of proton therapy relative to other modalities of reirradiation.

ACS NSQIP Risk Calculator

The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) calculator is meant to provide an estimation of perioperative risk. Our goal was to determine the clinical applicability of the calculator in major head and neck surgery. A retrospective chart review was completed for major head and neck operations performed at 1 institution from 2013 to 2014. The calculated perioperative complication risks from the ACS NSQIP calculator were compared with observed complication rates. Overall, the ACS NSQIP calculator had little predictive value for pneumonia, surgical site infection, 30-day return to operating room, or length of stay within this cohort ( P > .05). The calculator appears to have some value predicting total numbers of complications but has poor performance predicting an individual’s risk of suffering a perioperative complication. In conclusion, in our small cohort of patients, the ACS NSQIP calculator was a poor predictor of perioperative complications following major head and neck operations.

Management outcomes following lateral temporal bone resection for ear and temporal bone malignancies

Objective

To evaluate clinical outcomes following lateral temporal bone resection (LTBR) for management of malignancies involving the ear or temporal bone.

Subjects and Methods

A retrospective medical record review was performed on patients receiving LTBR for management of malignancies involving the ear or temporal bone between 1990 and 2007.

Results

In this group of 35 patients, the mean age was 62.7 years, with tumor histopathologies including squamous cell carcinoma (SCC, 20), basal cell carcinoma (BCC, 7), adenoid cystic carcinoma (ACC, 7), and adenocarcinoma (1). The 5-year overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were 77%, 79%, and 52%, respectively. Complete resection resulted in improved OS, DSS, and DFS ( P < 0.004 for each) and reduced local recurrence ( P < 0.001).

Conclusions

In patients with carcinomas of the ear and temporal bone, upfront excision including LTBR is an effective management when combined with postoperative radiation therapy. Complete removal of all disease may improve survival and decrease recurrence.

Acute toxicity in comprehensive head and neck radiation for nasopharynx and paranasal sinus cancers: cohort comparison of 3D conformal proton therapy and intensity modulated radiation therapy

BACKGROUND

To evaluate acute toxicity endpoints in a cohort of patients receiving head and neck radiation with proton therapy or intensity modulated radiation therapy (IMRT).

METHODS

Forty patients received comprehensive head and neck radiation including bilateral cervical nodal radiation, given with or without chemotherapy, for tumors of the nasopharynx, nasal cavity or paranasal sinuses, any T stage, N0-2. Fourteen received comprehensive treatment with proton therapy, and 26 were treated with IMRT, either comprehensively or matched to proton therapy delivered to the primary tumor site. Toxicity endpoints assessed included g-tube dependence at the completion of radiation and at 3 months after radiation, opioid pain medication requirement compared to pretreatment normalized as equivalent morphine dose (EMD) at completion of treatment, and at 1 and 3 months after radiation.

RESULTS

In a multivariable model including confounding variables of concurrent chemotherapy and involved nodal disease, comprehensive head and neck radiation therapy using proton therapy was associated with a lower opioid pain requirement at the completion of radiation and a lower rate of gastrostomy tube dependence by the completion of radiation therapy and at 3 months after radiation compared to IMRT. Proton therapy was associated with statistically significant lower mean doses to the oral cavity, esophagus, larynx, and parotid glands. In subgroup analysis of 32 patients receiving concurrent chemotherapy, there was a statistically significant correlation with a greater opioid pain medication requirement at the completion of radiation and both increasing mean dose to the oral cavity and to the esophagus.

CONCLUSIONS

Proton therapy was associated with significantly reduced radiation dose to assessed non-target normal tissues and a reduced rate of gastrostomy tube dependence and opioid pain medication requirements. This warrants further evaluation in larger studies, ideally with patient-reported toxicity outcomes and quality of life endpoints.

Head and Neck Paragangliomas

Objective

Head and neck paragangliomas are a group of slow-growing hypervascular tumors associated with the paraganglion system. The approach to evaluate and treat these lesions has evolved over the last 2 decades. While radical surgery had been the traditional approach, improvements in diagnostic imaging as well as radiation therapy techniques have led to an emphasis on observation and nonsurgical therapy in many patients. This article reviews the contemporary approach to the workup and management of head and neck paragangliomas.

Data Source

Articles were identified from PubMed.

Review Methods

PubMed searches with the following keywords were performed: carotid body paraganglioma management, vagal paraganglioma management, jugulotympanic paraganglioma management, imaging of head and neck paragangliomas, head and neck paraganglioma embolization, paraganglioma radiation, head and neck paraganglioma management, observation of head and neck paragangliomas, bilateral carotid body paragangliomas, and genetics of paragangliomas. Review and original research articles available in the English language and published during or after 2009 were selected on the basis of their clinical relevance and scientific strength. Certain articles published prior to 2009 were also included if they provided background information that was relevant.

Conclusions/Implications for Practice

Workup and treatment of head and neck paragangliomas are changing. With more now known regarding the longitudinal behavior of these tumors, observation and nonsurgical therapy are indicated in many instances. For patients where surgery is the most appropriate option, improved diagnostic and perioperative techniques are allowing patients to tolerate resection, often with reduced morbidity.

The new Australian Primary Health Networks: how will they integrate public health and primary care?

On 1 July 2015, the Australian Government established 31 new Primary Health Networks (PHNs), following a review by its former Chief Medical Officer, John Horvath, of 61 Medicare Locals created under the previous Labor administration. The Horvath review recommended, among other things, that new, larger primary health organisations be established to reduce fragmentation of care by integrating and coordinating health services, supporting the role of general practice, and leveraging and administering health program funding. The two main objectives of the new PHNs, as stated on the Department of Health's website, are "increasing the efficiency and effectiveness of medical services for patients, particularly those at risk of poor health outcomes, and improving coordination of care to ensure patients receive the right care in the right place at the right time". Below are three viewpoints, commissioned for this primary health care themed issue of Public Health Research & Practice, from the Australian Government Department of Health, the Public Health Association of Australia and a Sydney-based PHN. We asked the authors to focus particularly on how the newly established networks might help to integrate public health within the primary health care landscape. Our authors have pointed out the huge overlap between public health and primary care and looked at evidence showing the great benefits for health systems of collaboration between the two. Challenges ahead include a possible government focus on delivery of 'frontline' medical services, which may come at the expense of population health, and the complexity of dealing with all primary health care stakeholders, including health professionals, Local Health Districts, nongovernment organisations, research institutions and local communities.

The use of a prefabricated radial forearm free flap for closure of a large tracheocutaneous fistula: a case report and review of the literature

INTRODUCTION

The closure of complex tracheocutaneous fistulae is a surgical challenge. We describe a staged approach for management of a patient with a large tracheocutaneous fistula in the setting of prior surgery and local radiation therapy.

CASE PRESENTATION

A 66-year-old Caucasian man who had undergone prior surgery and radiation therapy to the lower neck presented to our hospital for treatment of a large tracheocutaneous fistula that had developed with an adjacent area of tracheal stenosis. A prefabricated composite graft made up of an inner mucosal lining (buccal mucosa), a central cartilage structure (conchal cartilage), and external skin lining was constructed on the patient's distal volar forearm and subsequently harvested in a staged fashion. This graft was transferred as a free flap and successfully used to close the patient's defect following revascularization. Sixty months after surgery, the patient had no airway compromise or new dysphonia.

CONCLUSIONS

The use of a prefabricated mucosally lined composite graft can allow for successful closure of large tracheocutaneous fistulae, even in the setting of prior radiation therapy.

Proton therapy for head and neck adenoid cystic carcinoma: initial clinical outcomes

BACKGROUND

The purpose of this study was to report outcomes of proton therapy in head and neck adenoid cystic carcinoma.

METHODS

We conducted a retrospective analysis of 26 patients treated between 2004 and 2012. Twenty patients (77%) had base of skull involvement; 19 (73%) were treated for initial disease and 7 (27%) for recurrent disease. Twenty patients were treated postoperatively, 6 after biopsy alone and 24 had positive margins or gross residual disease.Median dose delivered was 72 Gy (relative biological effectiveness[RBE]).

RESULTS

Median follow-up was 25 months (range, 7–50 months). The 2-year overall survival was 93% for initial disease course and 57% for recurrent disease (p5.19). The 2-year local control was 95% for initial disease and 86% for recurrent disease (p5.48). The 2-year distant metastatic rate was 25%. Late toxicity of grade 0 or 1 was seen in 17 patients, grade 2 in 5, grade 3 in 2, grade 4 in 1, and grade 5 in 1.

CONCLUSION

Initial outcomes of proton therapy are encouraging. Longer follow-up is required.

The "HPV Discussion": Effective Use of Data to Deliver Recommendations to Patients Impacted by HPV

OBJECTIVE

The dramatic rise in oropharyngeal squamous cell carcinoma associated with the human papilloma virus (HPV) has brought significant change to the interaction between patients and head and neck oncologists. HPV-induced cancers are generally the result of elements from the patient's sexual history, and otolaryngologists are generally less experienced than primary care physicians in addressing patient questions relating to sexual history and practices. This article addresses questions commonly posed by patients relating to HPV-induced head and neck cancers, issues related to HPV vaccination, and surveillance of HPV-related lesions. Supporting data are provided such that physicians may be better equipped to sufficiently address patient queries on this topic.

DATA SOURCES

Available peer-reviewed literature and clinical practice guidelines.

REVIEW METHODS

Assessment and discussion of specific topics by authors selected from the Head and Neck Surgery Education Committee of the American Academy of Otolaryngology-Head and Neck Surgery Foundation.

RESULTS

An educational "miniseminar" resulted in a notable increase in attendee knowledge and comfort regarding oropharyngeal squamous cell carcinoma counseling for patients in the setting of HPV-positive disease.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The dramatic increase in HPV-associated head and neck cancers has resulted in a changed paradigm of the physician-patient interaction. Care providers in today's environment must be prepared to counsel patients regarding sexually transmitted diseases and high-risk sexual behaviors. Examination of the existing data provides the foundation with which to construct a framework in which physicians can effectively communicate information and recommendations as they pertain to HPV-related carcinoma.
