Pathologic complete response following low-dose radiation for advanced oral cavity cancer in a patient with human immunodeficiency virus.

BACKGROUND: Advanced squamous cell carcinoma (SCCa) of the oral cavity is often not amenable to curative-intent therapy due to tumor location, tumor size, or comorbidities. CASE PRESENTATION: A 51-year-old male patient with human immunodeficiency virus and on highly active antiretroviral therapy (HAART) presented with a cT4aN2c SCCa of the tongue. He received a preoperative single course of Quad-Shot radiation therapy to 14 Gy in 4 fractions followed by surgical resection. Patient had no residual carcinoma on surgical pathology and no evidence of disease on subsequent clinical and radiological exams. CONCLUSIONS: To our knowledge, this is the first case of pathologic complete response for a patient on HAART following a single cycle of the Quad-Shot regimen for advanced oral cavity SCCa. Protease inhibitors in HAART can induce spontaneous tumor regression via inhibition of proteasome function and activation of apoptosis, and thus act as a cancer therapeutic.

Primary Dural Repair Using Titanium Microclips Following Lateral Skull Base Surgery.

Objective Standard techniques for primary dural repair following lateral skull base surgery are both technically challenging and time consuming without the potential for primary dural repair. Inadequate closure may result in postoperative cerebrospinal fluid (CSF) leak infectious sequalae. Traditional methods of dural repair rely on secondary obliteration of the CSF fistula. We hypothesized that the use of nonpenetrating titanium microclips may serve as a useful adjunct in primary dural repair or the establishment of an immobile repair layer following lateral skull base surgery. Methods Here, we report a novel technique for primary dural repair using nonpenetrating titanium microclips as an adjunct to standard techniques in a series of six patients with lateral skull base pathologies. Results A total of six consecutive lateral skull base tumor patients with titanium microclip dural reconstruction were included in our case series. Lateral skull base pathologies represented in this group included two jugular foramen schwannomas, one vestibular schwannoma, one petroclival meningioma, one glomus jugulare paraganglioma, and one jugular foramen chordoid meningioma. Conclusion To our knowledge, this is the first report on the use of microclips in repairing dural defects following lateral skull base surgery. Surgical outcomes for this small case series suggest that dural repair of the later skull base with nonpenetrating titanium microclips is a useful adjunct in dural repair following lateral skull base surgery.

Primary hyperparathyroidism: Disease of diverse genetic, symptomatic, and biochemical phenotypes.

Genetic, symptomatic, and biochemical heterogeneity of patients with primary hyperparathyroidism (PHPT) has become apparent in recent years. An in-depth, evidence-based review of the phenotypes of PHPT was conducted. This review was intended to provide the resulting information to surgeons who operate on patients with hyperparathyroidism. This review revealed that the once relatively clear distinction between familial and sporadic PHPT has become more challenging by the finding of various germline mutations in patients with seemingly sporadic PHPT. On the one hand, the genetic and clinical characteristics of some syndromes in which PHPT is an important component are now better understood. On the other hand, knowledge is emerging about novel syndromes, such as the rare multiple endocrine neoplasia type IV (MEN4), in which PHPT occurs frequently. It also revealed that, currently, the classical array of symptoms of PHPT is seen rarely upon initial presentation for evaluation. More common are nonspecific, nonclassical symptoms and signs of PHPT. In areas of the world where serum calcium levels are checked routinely, most patients today are "asymptomatic" and they are diagnosed after an incidental finding of hypercalcemia; however, some of them have subclinical involvement of bones and kidneys, which is demonstrated on radiographs, ultrasound, and modern imaging techniques. Last, the review points out that there are three distinct biochemical phenotypes of PHPT. The classical phenotype in which calcium and parathyroid hormone levels are both elevated, and other disease presentations in which the serum levels of calcium or intact parathyroid hormone are normal. Today several, distinct phenotypes of the disease can be identified, and they have implications in the diagnostic evaluation and treatment of patients, as well as possible screening of relatives.

Commentary on the management of total laryngectomy patients during the COVID-19 pandemic.

The coronavirus disease-2019 (COVID-19) pandemic has rapidly spread across the world, placing unprecedented strain on the health care system. Health care resources including hospital beds, ICUs, as well as personal protective equipment are becoming increasingly rationed and scare commodities. In this environment, the laryngectomee (patient having previously undergone a total laryngectomy) continues to represent a unique patient with unique needs. Given their surgically altered airway, they pose a challenge to manage for the otolaryngologist within the current COVID-19 pandemic. In this brief report, we present special considerations and best practice recommendations in the management of total laryngectomy patients. We also discuss recommendations for laryngectomy patients and minimizing community exposures.

Anterior cervical discectomy and fusion requiring resection of the superior horn of thyroid cartilage: case report.

Anterior cervical discectomy and fusion (ACDF) is the most common surgical procedure utilized for degenerative diseases of the cervical spine. The authors present the case of a 64-year-old man who underwent an ACDF for degenerative changes causing cervical stenosis with myelopathy. The patient's symptoms consisted of pain and weakness of the bilateral upper extremities that slowly progressed over 1.5 years. During the procedure, the superior horn of the thyroid cartilage impeded proper retraction, preventing adequate visualization due to its prominent size. At this point, otorhinolaryngology was consulted, which allowed for safe resection of this portion of the thyroid cartilage while preserving nearby critical structures. With the frequent usage of this surgical approach for various etiologies, the importance of proper recognition and consultation is paramount. Encountering prominent thyroid cartilage resulting in surgical obstruction has not been described in the literature and this report represents a paradigm for the proper course of action.

Does perioperative oxandrolone improve nutritional status in patients with cachexia related to head and neck carcinoma?

BACKGROUND: Cancer cachexia affects up to over 50% of advanced head and neck cancer (HNC) patients. To date, the potential utility of anabolic steroids in perioperative cachectic HNC patients has not been determined. METHODS: Retrospective review of pre- and post-oxandrolone administration prealbumin levels in 18 perioperative HNC patients between October 2007 and October 2014 at a tertiary academic medical center. RESULTS: The median pretreatment prealbumin was 88.5 mg/L. The median post-treatment prealbumin was 227 mg/L. The median interval improvement of the prealbumin level was 131.5 mg/L. The median differences between the pretreatment and post-treatment prealbumin levels were found to be statistically significant (P < .001). Subjective improvement in wound healing was also observed. CONCLUSIONS: Perioperative administration of oxandrolone resulted in objective improvements in prealbumin levels and subjective improvements in surgical wounds. Oxandrolone administered 10 mg twice daily (BID) for 10 days may be a useful adjunct in the perioperative care of nutritionally deficient HNC patients who are at risk for or have demonstrated impaired wound healing.

Ultrasound-Guided Fine-Needle Aspiration With Optional Core Needle Biopsy of Head and Neck Lymph Nodes and Masses: Comparison of Diagnostic Performance in Treated Squamous Cell Cancer Versus All Other Lesions.

OBJECTIVES: To evaluate the diagnostic performance of ultrasound (US)-guided fine-needle aspiration with optional core needle biopsy of head and neck lymph nodes and masses, with attention to differences between biopsy of treated squamous cell carcinoma (SCC) and biopsy of other lesions. METHODS: Institutional Review Board approval was obtained, and the need for consent was waived for this retrospective study. All 861 US-guided biopsies of head and neck lymph nodes and masses performed between March 1, 2012, and May 16, 2016, were reviewed. RESULTS: Of the 861 biopsies, 53 targeted SCC with residual masses after treatment. The biopsy procedures yielded benign or malignant pathologic results in 71.7% (38 of 53) of treated SCC and 90.7% (733 of 808) of all other lesions (P < .001). A reference standard based on subsequent pathologic results or clinical and imaging follow-up was established in 68.4% of procedures. In cases with benign or malignant biopsy results and a subsequent reference standard, the sensitivity values for malignancy were 87.5% (95% confidence interval, 64.0%-96.5%) in treated SCC and 98.3% (95% confidence interval, 96.0%-99.3%) in all other cases (P = .047), and the specificity values were 63.6% (95% confidence interval, 35.4%-84.8%) in treated SCC and 99.5% (95% confidence interval, 97.3%-99.9%) in all other cases (P < .001). There were no major complications related to the biopsy procedures. CONCLUSIONS: Excluding treated SCC, US-guided fine-needle aspiration with optional core needle biopsy of head and neck lymph nodes and masses has excellent diagnostic performance. Needle biopsy of head and neck SCC with a residual mass after therapy has a high rate of nondiagnostic samples, suboptimal sensitivity, and poor specificity.

Fine-needle aspiration with selective use of core needle biopsy of major salivary gland tumors.

OBJECTIVES: Preferential use of fine-needle aspiration (FNA) versus core needle biopsy (CNB) for distinguishing benign from malignant major salivary gland tumors is highly debated. The main disadvantage of FNA is lower sensitivity, whereas arguments against CNB include use of a larger bore needle and greater risk of complications. The aim of this study is to evaluate our experience performing ultrasound-guided (UG) FNA with selective use of CNB based on preliminary cytopathology, and to determine whether our preoperative diagnostic approach is more sensitive and specific than FNA alone-and at least as sensitive and specific as CNB alone. STUDY DESIGN: Retrospective review of UG needle biopsy sampling of lesions arising in or around parotid and submandibular glands. METHODS: Ultrasounds of 141 needle biopsies were identified. Patient/lesion/needle biopsy characteristics, preliminary cytopathology, final pathology, imaging studies, and subsequent clinical course and treatment were documented. RESULTS: Needle biopsies performed according to our protocol provided results that guided clinical decision making in 125 of 135 cases, 92.6% (95% confidence interval [CI], 86.8%-96.4%) of the time. Using 41 cases that had histologic verification, sensitivity was 100% (95% CI, 79.6%-100%), and specificity was 92.3% (95% CI, 75.9%-97.9%) for detecting malignancy. We definitively characterized 120 lesions as benign (84) or malignant (36). CONCLUSION: Preoperative needle biopsy diagnoses allowed clinical management to progress 92.6% of the time. The protocol of FNA with selective use of CNB may potentially reduce patient exposure to risks associated with CNB without the tradeoff of lower sensitivity seen with FNA. LEVEL OF EVIDENCE: 4.

Malignant Peripheral Nerve Sheath Tumor of the C2 Nerve Root: Case Report.

Here we present the case of a 36-year-old man who was found to have a symptomatic malignant neural sheath tumor growing from the C2 nerve root following a period of progressively worsening headaches. The patient was successfully treated with surgical resection resulting in resolution of cranial nerve deficits. Though uncommon, malignant peripheral nerve sheath tumor must be considered in the differential diagnosis of tumors involving the cervical nerve roots and carotid space.

Exploratory Factor Analysis of NRG Oncology's University of Washington Quality of Life Questionnaire-RTOG Modification.

CONTEXT: The 15-item University of Washington Quality of Life questionnaire-Radiation Therapy Oncology Group (RTOG) modification (UW-QOL-RTOG modification) has been used in several trials of head and neck cancer conducted by NRG Oncology such as RTOG 9709, RTOG 9901, RTOG 0244, and RTOG 0537. OBJECTIVES: This study is an exploratory factor analysis (EFA) to establish validity and reliability of the instrument subscales. METHODS: EFA on the UW-QOL-RTOG modification was conducted using baseline data from NRG Oncology's RTOG 0537, a trial of acupuncture-like transcutaneous electrical nerve stimulation in treating radiation-induced xerostomia. Cronbach α coefficient was calculated to measure reliability; correlation with the University of Michigan Xerostomia Related Quality of Life Scale was used to evaluate concurrent validity; and correlations between consecutive time points were used to assess test-retest reliability. RESULTS: The 15-item EFA of the modified tool resulted in 11 items split into four factors: mucus, eating, pain, and activities. Cronbach α ranged from 0.71 to 0.93 for the factors and total score, consisting of all 11 items. There were strong correlations (ρ ≥ 0.60) between consecutive time points and between total score and the Xerostomia Related Quality of Life Scale total score (ρ > 0.65). CONCLUSION: The UW-QOL-RTOG modification is a valid tool that can be used to assess symptom burden of head and neck cancer patients receiving radiation therapy or those who have recently completed radiation. The modified tool has acceptable reliability, concurrent validity, and test-retest reliability in this patient population, as well as the advantage of having being shortened from 15 to 11 items.

Xerostomia health-related quality of life: NRG oncology RTOG 0537.

PURPOSE: The purpose of this secondary analysis was to determine change in overall health-related quality of life (HRQOL) based on patient data obtained from NRG Oncology RTOG 0537 as measured by the RTOG-modified University of Washington Head and Neck Symptom Score (RM-UWHNSS). METHODS: A multi-site prospective randomized clinical trial design stratified 137 patients with post-radiation therapy xerostomia according to prior pilocarpine (PC) treatment and time after radiation therapy and/or chemotherapy and randomized patients into two groups. Patients were assigned to acupuncture or PC. Twenty-four sessions of acupuncture-like transcutaneous electrical nerve stimulation (ALTENS) were administered over 12 weeks, or oral PC (5 mg) three times daily over the same 12 weeks. The RM-UWHNSS was administered at baseline and at 4, 6, 9, and 15 months after the date of randomization. RESULTS: There were no between-arm differences in change scores on the RM-UWHNSS in the individual items, total score, or factor scores. For statistical modeling, race and time were significant for all outcomes (total and factor scores), while treatment arm was not significant. The ALTENS arm showed greater yet nonsignificant improvement in outcomes compared to the PC arm. CONCLUSION: Although no significant treatment differences were seen in this trial, patients receiving ALTENS consistently had lower scores, indicating better function, as compared to those receiving PC. Radiation-induced xerostomia improved over time for all patients.

Fistula rates after salvage laryngectomy: comparing pectoralis myofascial and myocutaneous flaps.

OBJECTIVES/HYPOTHESIS: Salvage laryngectomy after failed organ preservation often has a high complication rate, pharyngocutaneous fistulas being the most common. These fistulas increase morbidity, prolong hospitalization, and potentially delay adjuvant treatment. Fistula rates in the literature range from 3% to 65%. Use of the pectoralis flap to prevent fistula formation has been adopted as a common practice at our institution. A review of our experience using the overlay myofascial showed a higher than desired complication rate. The aim of this study is to assess whether the use of integrated myocutaneous flap results in a lower fistula rate. STUDY DESIGN: A retrospective review of 30 patients followed by a pilot study of 10 patients. All underwent salvage laryngectomy after failed organ preservation. METHODS: The operation notes of 40 laryngectomy patients were analyzed. The patient/tumor characteristics, pretreatment, neck dissection, flap type, and fistula rate were documented. RESULTS: The patient sample was 25% female. All patients received prior radiotherapy, but only 37.5% received prior chemoradiation. Neck dissections were performed in 80% of these patients, 76% of the myocutaneous group, and 84% of the myofascial group. Advanced tumor stage was found in 42% of the myofascial group and 52% of the myocutaneous group. Five of the 19 myofascial patients developed a fistula, whereas seven of the 21 myocutaneous patients developed a fistula. CONCLUSIONS: The use of the pectoralis myocutaneous flap (PMCF) in this pilot series did not show a lower rate of fistula; other alternatives should be pursued to decrease this complication. LEVEL OF EVIDENCE: 4.

Prophylactic PEG placement in head and neck cancer: how many feeding tubes are unused (and unnecessary)?

AIM: To determine the rate of use and non-use of prophylactic percutaneous endoscopic gastrostomy (PEG) tubes among patients with head and neck cancer (HNC) patients. METHODS: All patients with HNC undergoing PEG between January 1, 2004 and June 30, 2006 were identified. Patients (or their next-of-kin) were surveyed by phone and all available medical records and cancer registry data were reviewed. Prophylactic PEG was defined as placement in the absence of dysphagia and prior to radiation or chemoradiation. Each patient with a prophylactic PEG was assessed for cancer diagnosis, type of therapy, PEG use, and complications related to PEG. RESULTS: One hundred and three patients had PEG tubes placed for HNC. Thirty four patients (33%) could not be contacted for follow-up. Of the 23 (22.3%) patients with prophylactic PEG tubes, 11/23 (47.8%) either never used the PEG or used it for less than 2 wk. No association with PEG use vs non-use was observed for cancer diagnosis, stage, or specific cancer treatment. Non-use or limited use was observed in 3/6 (50%) treated with radiation alone vs 8/17 (47.1%) treated with chemoradiation (P = 1.0), and 3 of 10 (30%) treated with surgery vs 8 of 13 (62%) not treated with surgery (P = 0.21). Minor complications were reported in 5/23 (21.7%). One (4.3%) major complication was reported. CONCLUSION: There is a high rate of unnecessary PEG placement when done prophylactically in patients with head and neck cancer.

Hyaluronic acid hydrogel sustains the delivery of dexamethasone across the round window membrane.

BACKGROUND: The use of intratympanic (IT) steroids for the treatment of inner ear disorders is promising, but the clinical challenges of prolonged middle ear drug application have proven burdensome, and a sustainable delivery system is yet to be developed. METHOD: In this study, a guinea pig model was used to determine if dexamethasone in combination with a hyaluronic-acid (HA)-based hydrogel is an efficient, stable and sustainable dexamethasone delivery system to the inner ear. For each animal, right and left middle ear bullae were randomly selected to be filled with dexamethasone alone or dexamethasone-HA (Dex-HA) gel. Perilymph samples were collected at different time points and dexamethasone levels were determined using an ELISA. RESULTS: Dexamethasone was measurable in the perilymph samples up to 72 h after treatment. At 24 h after treatment, the perilymph dexamethasone concentrations were significantly higher (p = 0.01) in the ears treated with Dex-HA gel than in those treated with dexamethasone alone. While the perilymph dexamethasone concentration had decreased at 48 h after treatment with Dex-HA gel, the levels were still higher than those observed at 24 h in ears treated with dexamethasone alone. A high variability in dexamethasone concentration was observed between the samples, and the variability between matched ears receiving different treatments was remarkably lower than the variability within each treatment group, suggesting that individual parameters might play a major role in perilymph dexamethasone concentration. There was no statistically significant correlation between dexamethasone concentration and sex, weight or laterality. CONCLUSIONS: Our results show that the Dex-HA gel used in this study provides an effective and sustained dexamethasone release mechanism that might be utilized to treat conditions such as sudden sensorineural hearing loss. This could potentially reduce the morbidity and costs associated with IT treatment.

Tonsillar carcinoma in the contralateral tonsil.

OBJECTIVE: We report a series of patients treated for carcinoma of the tonsil who either presented with bilateral carcinomas or later developed a second primary carcinoma of the contralateral tonsil. This report raises awareness of this occurrence. STUDY DESIGN: Case series. METHODS: Four cases have been identified of either concomitant or subsequent carcinoma of the contralateral tonsil inpatients treated for tonsillar carcinoma from the practices of 3 head and neck surgeons in a single demographic area over a 35 year span. RESULTS: Four patients were identified who were treated for tonsillar carcinoma with concomitant or subsequent carcinoma of the contralateral tonsil: One patient with bilateral metastatic carcinoma in cervical lymph nodes was found to have bilateral occult tonsillar primaries.Three patients who were treated for tonsillar primary carcinomas subsequently developed carcinoma of the contralateral tonsil. CONCLUSIONS: A small population of patients with unilateral tonsil carcinoma will developed a second in the contralateral tonsil. This raises the question of whether removal of the contralateral tonsil at the time of initial treatment might have spared the morbidity/mortality of the subsequent contralateral tonsil cancer.

Necrotizing fasciitis secondary to bisphosphonate-induced osteonecrosis of the jaw.

Osteonecrosis of the jaw is an uncommon consequence of biphosphonate therapy. This has most commonly been a bone complication with little if any soft tissue involvement. An unusual case of necrotizing fasciitis with extensive soft tissue infection stemming from a prolonged case of osteonecrosis of the jaw presented. The management of this patient (aggressive surgical debridement and prolonged wound care) is reviewed as well as the review of the underlying processes.

Early oral feeding after salvage laryngectomy.

BACKGROUND: Our aim was to determine the feasibility and safety of initiating early oral feeding in patients who underwent salvage laryngectomy on postoperative day 5 and to review the rate of pharyngocutaneous fistula formation. METHODS: A retrospective review of 29 patients who underwent salvage laryngectomy was completed. Patients included in the study had radiation therapy +/- chemotherapy for laryngeal squamous cell carcinoma with subsequent total laryngectomy. Patients were excluded from analysis if they were reliant on a gastrostomy tube preoperatively, had a concurrent complete glossectomy, or developed a fistula before beginning oral feedings. Early oral feeding was initiated on postoperative day 5. RESULTS: Twenty patients met complete inclusion criteria. Pharyngocutaneous fistula occurred in 10% (2/20) of the patients. Patients without postoperative complications on an average remained in the hospital for 7 days. CONCLUSIONS: The risk of fistula formation is not increased and the duration of hospital stay may be shortened in patients who were given early postoperative feeds.

Treatment of base of tongue cancer with paclitaxel, ifosfamide, and cisplatinum induction chemotherapy followed by chemoradiotherapy.

OBJECTIVES/HYPOTHESIS: To assess the efficacy of paclitaxel, ifosfamide, and cisplatinum induction chemotherapy plus concurrent chemoradiation in the treatment of stage III and IV base of tongue cancer. STUDY DESIGN: Subgroup analysis of patients with base of tongue cancer enrolled in a single-institution prospective phase II trial, evaluating an organ-preservation approach in the treatment of locally advanced head and neck cancer. METHODS: Eighteen patients with tumors ranging from stage T2-T4, any N, or M0 were treated with a protocol of induction chemotherapy, with Taxol, ifosfamide, cisplatin every 21 days for up to three cycles. If the primary tumor exhibited a complete or partial response, patients were treated with radiation and weekly taxol and carboplatin for 7 weeks. Surgery was used for those with less than partial response or disease progression. Neck dissection was performed in cases with clinical or radiological evidence of persistent disease in the neck 6 to 8 weeks after completion of treatment. RESULTS: Sixteen patients were male and two were female; the average age was 55 years (range, 43-65). Fifteen patients had stage IV disease and three had stage III disease. Of the 18 patients initially enrolled, 17 patients had a complete response. All 17 patients had no evidence of loco-regional disease at a median follow-up of 29.6 months. Only 1 of them developed distant metastases 30 months after completion of treatment. Three patients required permanent percutaneous endoscopic gastrostomy tubes because of severe dysphagia associated with concurrent chemoradiation. CONCLUSIONS: The treatment regimen studied is remarkably effective in stage III and IV base of tongue cancer with 100% of patients completing the protocol alive to date. Although some patients required persistent percutaneous endoscopic gastrostomy use, no patient experienced significant enough toxicity during the protocol to delay or withdraw from treatment.

Is there a role for fluorodeoxyglucose positron emission tomography/computed tomography in cytologically indeterminate thyroid nodules?

OBJECTIVE: The aim of this study was to determine the accuracy of the fluorine 18 ((18)F)-labeled fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) scan in the evaluation of thyroid nodules in which the cytopathology of fine-needle aspiration (FNA) biopsies are classified as "indeterminate," ie, either follicular or Hürthle cell lesion. METHODS: At an academic medical center, we conducted a prospective pilot study of 15 patients with thyroid nodules in whom adequate FNA was diagnosed as indeterminate. All patients underwent a whole-body FDG-PET/CT scan followed by thyroidectomy. Preoperative FDG-PET/CT results and the histopathology of the surgical specimen were compared and statistically analyzed. RESULTS: The FNA demonstrated follicular cells in 11 (73%) patients, Hürthle cells in 3 (20%) patients, and both types of cells in 1 (7%) patient. The histopathology of the surgical specimen revealed thyroid cancer in 7 (47%) patients. The FDG-PET/CT scan was positive in 8 patients; 4 (50%) patients were found to have cancer. The FDG-PET/CT scan was negative in 7 patients. Four of these patients had benign lesions and 3 had thyroid carcinoma. Thus, 4 (27%) patients had false-positive FDG-PET/CT scans and 3 (20%) patients had false-negative studies. The sensitivity of FDG-PET/CT to detect a malignant focus was 57% with a specificity of 50%. The positive predictive value was 50% and the negative predictive value was 57%. CONCLUSIONS: In this pilot study of patients with cytologically indeterminate thyroid nodules, FDG-PET/CT was not a predictable indicator of benign or malignant disease. Although a larger series may elucidate a role for FDG-PET/CT, the relatively low predictability shown in this study should caution clinicians about using FDG-PET/CT to consider foregoing thyroidectomy for cytologically indeterminate nodules.
