Abstract
Squamous cell carcinoma of unknown primary of the head and neck (SCCUP) is a heterogeneous disease entity that requires careful examination to locate the occult primary. We examined the diagnostic value of expression of biomarkers, such as human papillomavirus (HPV), p16, and Epstein-Barr virus (EBV), in metastatic lymph nodes versus (18) F-fluorodeoxyglucose ((18) F-FDG) positron emission tomography/computed tomography (PET/CT). We prospectively enrolled 54 consecutive SCCUP patients who received HPV, p16, and EBV analyses of lymph node fine-needle aspirates and (18) F-FDG PET/CT scans and subsequently underwent examinations and biopsies under general anesthesia to detect primary tumors. The diagnostic performance of the biomarkers and (18) F-FDG PET/CT were compared by using receiver operating characteristics (ROC) curve analyses with histopathological results for identification of primary tumors. Primary tumors were identified in 28 (51.9%) of 54 patients: the palatine tonsil in 24, base of the tongue in 1, nasopharynx in 2, and hypopharynx in 1. The sensitivity of p16 (85.7%) and accuracy of HPV (85.2%) were higher than those (42.9% and 68.5%) of (18) F-FDG PET/CT (P < 0.05). The area under the ROC curve of HPV was higher than that of (18) F-FDG PET/CT (0.857 vs. 0.666, P = 0.007). The disease-free survival rates were higher in the patients with primary tumor detection or p16 nodal immunopositivity than in the other patients (P < 0.05). The results showed that HPV and p16 detection in metastatic lymph nodes can help locate hidden primary tumors, guide definitive treatment, and predict patient survival.

Minimally invasive surgery versus radiotherapy/chemoradiotherapy for small-volume primary oropharyngeal carcinoma.

Minimally invasive surgery versus radiotherapy/chemoradiotherapy for small-volume primary oropharyngeal carcinoma.

Cochrane Database Syst Rev. 2016 Dec 11;12:CD010963

Authors: Howard J, Masterson L, Dwivedi RC, Riffat F, Benson R, Jefferies S, Jani P, Tysome JR, Nutting C

Abstract
BACKGROUND: More than 400,000 cases of oropharyngeal squamous cell carcinoma (OPSCC) are diagnosed each year worldwide and the incidence is rising, partly as a result of human papillomavirus. Human papillomavirus-associated OPSCC affects younger patients and often presents at a higher stage; however, it is associated with a better prognosis.Until recently, first-line management of OPSCC involved chemoradiotherapy, as research had demonstrated comparable survival outcomes when compared with open surgery, with significantly decreased morbidity. However, interventions have now evolved with computerised planning and intensity-modulated radiotherapy, and the advent of endoscopic head and neck surgery, which provide the potential for decreased treatment-associated morbidity.The oropharynx plays an essential role in swallowing, speech and protecting the airway as it is situated at the bifurcation of the respiratory and digestive tracts. Treatment modality recommendations are based on survival outcomes. Given the younger patient demographic, establishing the safety of modalities that potentially have better functional outcome is becoming increasingly important.
OBJECTIVES: To assess the efficacy of endoscopic head and neck surgery (transoral robotic surgery or transoral laser microsurgery) for small-volume, primary (T1-2, N0-2) oropharyngeal squamous cell carcinoma (OPSCC) in comparison to radiotherapy/chemoradiotherapy.
SEARCH METHODS: The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2016, Issue 10); PubMed; EMBASE; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 8 November 2016.
SELECTION CRITERIA: Randomised controlled trials in patients with carcinoma in the oropharynx subsite (as defined by the World Health Organization classification C09, C10). Cancers included were primary squamous cell carcinomas arising from the oropharyngeal mucosa. The tumours were classified as T1-T2 with or without nodal disease and with no evidence of distant metastatic spread. The intervention was transoral, minimally invasive surgery with or without adjuvant radiotherapy or adjuvant chemoradiotherapy. The comparator was primary radiotherapy with or without induction or concurrent chemotherapy for the tumour. The treatments received and compared were of curative intent and patients had not undergone prior intervention, other than diagnostic biopsy.
DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. Our primary outcomes were overall survival (disease-related mortality was to be studied where possible), locoregional control, disease-free survival and progression-free survival or time to recurrence. All outcomes were to be measured at two, three and five years after diagnosis. Our secondary outcomes included quality of life, harms associated with treatment, patient satisfaction and xerostomia score.
MAIN RESULTS: No completed studies met the inclusion criteria for the review. Two ongoing trials fulfilled the selection criteria, however neither are complete.'Early-stage squamous cell carcinoma of the oropharynx: radiotherapy versus trans-oral robotic surgery (ORATOR)' is a phase II randomised controlled trial comparing primary radiation therapy with primary transoral robotic surgery for small-volume primary (T1-2, N0-2) OPSCC. It is currently in progress with an estimated completion date of June 2021.'European Organisation for Research and Treatment of Cancer 1420 (EORTC 1420-HNCG-ROG)' is a phase III, randomised study assessing the "best of" radiotherapy compared to transoral robotic surgery/transoral laser microsurgery in patients with T1-T2, N0 squamous cell carcinoma of the oropharynx and base of tongue. It was due to start accrual mid-2016.
AUTHORS' CONCLUSIONS: The role of endoscopic head and neck surgery in the management of OPSCC is clearly expanding as evidenced by its more overt incorporation into the current National Comprehensive Cancer Network guidelines. Data are mounting regarding its outcomes both in terms of survival and lower morbidity. As confidence increases, it is being used in the management of more advanced OPSCC.Based on this review, there is currently no high-quality evidence from randomised controlled trials regarding clinical outcomes for patients with oropharyngeal cancer receiving endoscopic head and neck surgery compared with primary chemoradiotherapy.

Salivary biomarkers in cancer detection.

Salivary biomarkers in cancer detection.

Med Oncol. 2017 Jan;34(1):7

Authors: Wang X, Kaczor-Urbanowicz KE, Wong DT

Abstract
Cancer is the second most common cause of death in the USA. Its symptoms are often not specific and absent, until the tumors have already metastasized. Therefore, there is an urgent demand for developing rapid, highly accurate and noninvasive tools for cancer screening, early detection, diagnostics, staging and prognostics. Saliva as a multi-constituent oral fluid comprises secretions from the major and minor salivary glands, extensively supplied by blood. Molecules such as DNAs, RNAs, proteins, metabolites, and microbiota, present in blood, could be also found in saliva. Recently, salivary diagnostics has drawn significant attention for the detection of specific biomarkers, since the sample collection and processing are simple, cost-effective, and precise and do not cause patient discomfort. Here, we review recent salivary candidate biomarkers for systemic cancers by dividing them according to their origin into: genomic, transcriptomic, proteomic, metabolomic and microbial types.

Influence of aqueous humor convection current on IOL opacification.

Influence of aqueous humor convection current on IOL opacification.

Int Ophthalmol. 2016 Dec 10;

Authors: Agresta A, Giudiceandrea A, Salgarello T, Manganelli C, Fasciani R, Caporossi A

Abstract
BACKGROUND AND PURPOSE: The opacification of Akreos Adapt (Bausch & Lomb, Rochester; NY) intraocular lens (IOL) has been previously reported in Literature. A metabolic change in aqueous humour was considered as the main trigger factor to IOL opacification. We report our case and discuss the association with Ex-PRESS, highlighting the particular pattern of IOL opacification and its possible relation with the intraocular convective motions of the aqueous.
MATERIAL AND METHODS: We analyzed our case using both digital slit lamp acquisition and OCT Visante (Zeiss, Germany) images. A literature review was conducted to evaluate our results with that previously reported.
CONCLUSION: The role of a relative stationary flow was reported as suggested concurrent mechanism in IOL opacification phenomenon.

Abstract
PURPOSE: Human epidermal growth factor receptor 3 (HER3) has been identified as an important component of many receptor tyrosine kinase-driven cancers. LJM716 is a human IgG monoclonal antibody that binds HER3, trapping it in an inactive conformation. In this study, a phase I dose escalation was performed with a primary objective to establish the maximum tolerated dose and/or the recommended dose of LJM716 in Japanese patients with selected advanced solid tumors. Secondary objectives included the evaluation of the safety and tolerability, preliminary antitumor activity, and pharmacokinetics of LJM716 in Japanese patients.
METHODS: LJM716 was administered intravenously at doses of 10, 20, or 40 mg/kg once weekly, in 28-day cycles, to 12 patients with HER2-amplified breast cancer or gastric cancer, or with esophageal squamous cell carcinoma or squamous cell carcinoma of the head and neck, regardless of HER2 status.
RESULTS: The maximum tolerated dose was not reached, and the recommended dose was established at 40 mg/kg. No dose-limiting toxicities were observed in the first cycle. The most frequently reported adverse events were diarrhea, fatigue, stomatitis, pyrexia, and paronychia. One unconfirmed partial response was observed in a patient with breast cancer, and 50% of the patients achieved stable disease as the best overall response. Exposure increased with ascending dose, and half-life was estimated to be 11-14 days. No anti-LJM716 antibodies were detected.
CONCLUSIONS: LJM716 was well tolerated in Japanese patients, and a degree of tumor shrinkage was observed.

Assessment of endolymphatic hydrops and otolith function in patients with Ménière's disease.

Assessment of endolymphatic hydrops and otolith function in patients with Ménière's disease.

Eur Arch Otorhinolaryngol. 2016 Dec 10;

Authors: Okumura T, Imai T, Takimoto Y, Takeda N, Kitahara T, Uno A, Kamakura T, Osaki Y, Watanabe Y, Inohara H

Abstract
Ménière's disease is associated with hydrops of the inner ear endolymphatic space, and histopathologically, the cochlea and vestibule are usually involved. We used gadolinium-enhanced magnetic resonance imaging and measured cervical and ocular vestibular evoked myogenic potentials and the gain in the utricular induced linear vestibulo-ocular reflex to test the hypothesis that vestibular hydrops in Ménière's disease patients is associated with otolith organ dysfunction. We evaluated 21 patients diagnosed with unilateral definitive Ménière's disease using gadolinium magnetic resonance imaging to detect endolymphatic hydrops in the cochlea and vestibule. Cervical and ocular vestibular evoked myogenic potentials and the gain in utricular induced linear vestibulo-ocular reflex during eccentric rotation were measured to assess otolith organ function. For eccentric rotation, patients were rotated while displaced from the axis of rotation, while linear acceleration stimulated the utricle and induced the vestibulo-ocular reflex. Magnetic resonance imaging revealed vestibular hydrops in 14 of 20 patients (70%). Among the 14 patients, ten (71%) had abnormal cervical and three (21%) had abnormal ocular vestibular evoked myogenic potentials. Four patients (4/21, 19%) had abnormal linear vestibulo-ocular reflexes, three of whom also had abnormal ocular vestibular evoked myogenic potentials. Overall, 16 of 17 patients had normal linear vestibulo-ocular reflexes and normal ocular vestibular evoked myogenic potentials. Vestibular endolymphatic hydrops in Ménière's disease patients caused otolith organ dysfunction, mainly in the saccule. The number of Ménière's disease patients with abnormal ocular vestibular evoked myogenic potentials was low (19%), and they also had abnormal utricular induced linear vestibulo-ocular reflexes.

Abstract
The prognosis is suboptimal in patients with locoregionally advanced laryngeal carcinoma even after multimodality protocols. The purpose of this study was to determine the potential influential factors that have an impact on the development of locoregional recurrence, distant metastasis, and oncological outcomes in patients with locoregionally advanced laryngeal carcinoma who had surgical multimodality protocols. A sample size of 85 cases was determined based on a power of 90% and an effect size of α 2 = 0.05. A retrospective analysis of 357 patients with a diagnosis of laryngeal cancer between 2002 and 2015 was performed. Eighteen variables based on sociodemographic, clinical, histopathological and treatment data were analyzed. Medical records of 85 consecutive patients with locoregionally advanced laryngeal carcinoma who underwent surgical multimodality protocols were reviewed. Five-year overall, disease-specific, disease-free, locoregional recurrence-free and distant metastasis-free survival were 68.7, 78.0, 69.6, 68.9 and 69.2%, respectively. Extracapsular extension was an independent predictive factor for locoregional recurrence. Pathologic tumor volume was an independent predictive factor for distant metastasis. pT-stage was an independent prognostic factor for 5-year overall survival, disease-free survival, locoregional recurrence-free survival and distant metastasis-free survival. High volume, pT4a laryngeal tumors with extracapsular extension are associated with a high risk of locoregional recurrence and distant metastasis; and have poor oncological outcomes in patients with locoregionally advanced laryngeal carcinoma treated with surgical multimodality protocols.
