PURPOSE: To evaluate the diagnostic performances of ultrasonographic (US) findings, computed tomography (CT) findings and fine needle aspiration cytology (FNAC) for the prediction of cervical lymph node (LN) metastases of papillary thyroid carcinoma (PTC) to determine which LN should be dissected. METHODS: 376 LNs in 302 patients who underwent both US-guided skin surface LN markings and CT before LN dissection were analyzed retrospectively. Indications for LN dissection were suspicious US findings of LN metastases (n = 300), suspicious CT findings (n = 67) or surgeon's request (n = 9)...

In the present study, we aim to compare the rationality of proposed N classification based on the number of metastatic lymph nodes (LNs) with the current one. A total of 509 penile cancer patients at our institute were analyzed. Univariable and multivariable statistical analyses were used to assess cancer-specific survival (CSS) in two staging systems. Harrell's concordance index was applied to evaluate predictive accuracy of the current and proposed N classification in predicting CSS. We propose a new classification: pN1 (metastasis in 1-2 regional LNs), pN2 (metastasis in 3 regional LNs, or three or fewer regional lymph nodes with extranodal extension), and pN3 (metastasis in 4 or more regional LNs)...

Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy) is a rare systemic histiocytic disorder of unknown etiology characterized by the accumulation of enlarged non-Langerhans histiocytes within lymph nodes and extranodal sites. The histiocytes display characteristic emperipolesis (nondestructive engulfment of inflammatory cells) and are CD68 and S100 positive and CD1a negative. Although extranodal disease frequently occurs with nodal involvement, isolated extranodal disease is uncommon. We report a case of isolated localized subcutaneous multinodular disease on FDG PET/CT...

The 8th edition of the American Joint Committee on Cancer (AJCC) Staging Manual introduces "depth of invasion" and "extranodal extension" into the head and neck section, and our aim was to find out if these changes have an impact on prognosis. We evaluated 174 patients who had had oral squamous cell carcinomas (SCC) resected between 2003 and 2012. The clinical records were reviewed, the patients' tumours restaged according to the 8th edition of the AJCC, and we analysed five-year survival to verify whether different correlations were made between the T and N stages and disease-specific survival using the 7th and 8th editions...

Importance: Nodal staging for laryngohypopharyngeal cancers is based primarily on size and laterality, with less value placed on absolute number of metastatic lymph nodes (LNs). We are aware of no studies to date that have specifically addressed the prognostic effect of quantitative nodal burden in larynx or hypopharynx malignancies. Objective: To assess the independent impact of quantitative metastatic LN burden on mortality risk. Design, Setting, and Participants: Univariate and multivariable models were constructed to evaluate the association between patients' number of metastatic LNs and their survival, adjusting for factors such as nodal size, laterality, extranodal extension, margin status, and adjuvant treatment...

Shao Hui Huang, Brian O'Sullivan, John Waldron
In the effort to control human papillomavirus-related oropharyngeal cancer, the head and neck oncology community has devoted much effort to understanding its disease biology and clinical behavior, and refining strategies to address early diagnosis and optimal management for the affected population. This review identifies articles published up to March 2017 on tumor biology and clinical implications of human papillomavirus-related oropharyngeal cancer, and summarizes the findings in some key areas. These include potential screening strategies, possible anatomical features responsible for early lymph node involvement and its implication for staging, biological mechanisms to explain superior outcomes compared to traditional nonviral-related mucosal cancers, re-appreciation of traditional prognostic factors (eg, hypoxia, extranodal extension, and smoking), and current efforts to optimize management for this patient population...

Nuzhat Husain, Azfar Neyaz
High-risk human papillomavirus (HR-HPV) is a causative agent for an increasing subset of oropharyngeal squamous cell carcinoma. HPV 16 accounts for 90% of cases. The chance for malignant transformation due to infection with high-risk HPV is proportional to the expression of the viral oncogene products E6 and E7, which inactivate p53 and retinoblastoma (Rb) tumor suppressor functions. P16 is a surrogate marker of HPV associated HNSCC and 2+/3+ expression in more than 75% cells is diagnostic. Molecular demonstration of integrated virus by in situ hybridization is specific but has low sensitivity...

Primary orbital lymphoma is a rare entity with only 1% of extranodal lymphomas. They usually present to ophthalmologist and surgical reserved for biopsy or tissue diagnosis. We present a patient who was referred to neurosurgery for a rapid growing orbital lymphoma. It grows from a small nodule in the eyelid to a huge, aggressive, disfiguring lesion invading bone and dura with intracranial extension within 3 months. The patient was treated with total surgical excision followed by systemic chemotherapy.

OBJECTIVES: Radiological extranodal extension (rENE) upon CT is obtained before concurrent chemoradiation therapy (CCRT) for head and neck squamous cell carcinoma (HNSCC). We evaluated the prognostic value of rENE, rather than pathologically proven ENE, in patients who received CCRT for HNSCC. MATERIALS AND METHODS: We reviewed 117 patients. We divided the patients into rENE(+) and rENE(-) groups and evaluated overall survival (OS) and disease-specific survival (DSS), and factors affecting these outcomes...

INTRODUCTION AND OBJECTIVES: Extranodal extension in nodal metastases is an independent adverse prognostic factor in head and neck squamous cell carcinoma patients. However, few studies specifically address the subgroup of patients with no clinical evidence of nodal disease. MATERIAL AND METHODS: We retrospectively analysed data from 348 head and neck squamous cell carcinoma patients without any previous treatment and lacking clinical or radiological evidence of neck node metastases during the initial workup, treated with an elective neck dissection between 1992-2014...

The presence of cervical lymph node metastases is a major prognostic factor in squamous cell carcinoma of the head and neck. The presence of a solitary ipsilateral metastatic lymph node reduces expected survival by almost 50%, and the presence of regional metastatic nodes at the time of presentation is the strongest predictor of recurrence or the development of distant metastases or both. Therefore, accurate identification of metastatic cervical lymph nodes is essential for staging and treatment planning. Pretreatment imaging is important for identifying clinically occult pathologic nodes as well as delineating nodal size and morphologic characteristics used in staging...

The updated eighth edition of the Cancer Staging Manual of the American Joint Committee on Cancer will be implemented in January 2018. There are multiple changes to the head and neck section of the manual, which will be relevant to radiologists participating in multidisciplinary head and neck tumor boards and reading pretreatment head and neck cancer scans. Human papillomavirus-related/p16(+) oropharyngeal squamous cell carcinoma will now be staged separately; this change reflects the markedly better prognosis of these tumors compared with non-human papillomavirus/p16(-) oropharyngeal squamous cell carcinoma...
