REVIEW
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...

BACKGROUND: The lymph node (LN) yield and ratio are considered important predictors of post-treatment outcomes for several human cancers. This study examined the association between nodal factors including the LN yield and ratio with recurrence after thyroidectomy plus central compartment neck dissection (ND) for papillary thyroid carcinoma (PTC). MATERIALS AND METHODS: This retrospective study involved 2384 consecutive patients who underwent a thyroidectomy plus central compartment ND combined with (n = 440) or without lateral compartment ND at our tertiary referral center between 2006 and 2012...

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...

BACKGROUND: The 8th edition American Joint Committee on Cancer (AJCC8) provides the same nodal staging system for mucosal and cutaneous squamous cell carcinoma of the head and neck (HNcSCC) and includes extranodal extension (ENE) as an adverse prognostic criterion. This study evaluates the prognostic efficacy of the AJCC8 pathologic nodal staging system (pN) for HNcSCC. METHODS: Univariate analysis of 382 patients with metastatic HNcSCC staged according to both the 7th (AJCC7) and the 8th edition staging systems...

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...

PURPOSE: The present study aimed to evaluate the clinicopathologic characteristics of patients with extranodal extension (ENE) and the prognostic implications of ENE in stage III colorectal cancer (CRC). RESULTS: ENE was more frequent in younger patients and those with rectal cancer, higher T stage, higher N stage, lymphovascular invasion (LVI), and perineural invasion (PNI). Five-year disease-free survival (DFS) and overall survival (OS) were lower in patients with ENE-positive than in those with ENE-negative tumors (DFS, 66...

We previously reported an extremely rare case of follicular dendritic cell sarcoma (FDCS) presented as a thyroid mass. Given the rarity of this disease, there are no personalized and molecularly targeted treatment options due to the lack of knowledge in the genomic makeup of the tumor. A 44-year-old white woman was diagnosed with an extranodal FDCS in thyroid. The patient underwent a total thyroidectomy, central compartment dissection, parathyroid re-implantation, and adjuvant radiation therapy. Tumor DNA sequencing of 236 genes by FoundationOne panel found truncating mutations in PTEN and missense mutations in RET and TP53...

Our aim was to find out first whether the extrinsic muscles of the tongue are histologically identifiable, and secondly to what degree the use of the new criteria in the 8th editions of the American Joint Committee on Cancer(AJCC)/Union for International Cancer Control (UICC) manuals (which have recognised the importance of depth of invasion of tumour, rather than invasion of the extrinsic muscles of the tongue and extranodal extension), will alter staging of lingual squamous cell carcinoma (SCC). The histological sections from 165 patients who had had primary resection of lingual SCC were reviewed, and one or more extrinsic muscles of the tongue was identified in 100 patients (61%), with the genioglossus seen the most often (in 96)...

BACKGROUND: The American Joint Commission on Cancer (AJCC) recently created new staging for human papillomavirus associated oropharyngeal cancer (HPV+ OPSCC) for its 8th edition. These proposals have not yet been validated in a national registry. METHODS: Review of National Cancer Database (NCDB) for surgically-treated HPV+ OPSCC for years 2010-2014 to validate the new staging system using the Kaplan Meier method to explore survival outcomes. RESULTS: 3745 cases were analyzed...

Angiomyomatous hamartoma of lymph nodes (AMH-LN) is an uncommon benign proliferation of smooth muscle, blood vessels, collagenous stroma and adipocytes, most commonly affecting inguinal LN. A similar constellation of cell types constitutes various members of the perivascular epithelioid cell tumor (PEComa) family, including lymphangioleiomyomatosis (LAM) which can involve LN in women. Because some LN-LAM patients have tuberous sclerosis complex (TSC) and/or other PEComa family lesions, it is clinically relevant to distinguish LN-LAM from AMH-LN...

Purpose Current staging systems for oral cavity cancers incorporate lymph node (LN) size and laterality, but place less weight on the total number of positive metastatic nodes. We investigated the independent impact of numerical metastatic LN burden on survival. Methods Adult patients with oral cavity squamous cell carcinoma undergoing upfront surgical resection for curative intent were identified in the National Cancer Data Base between 2004 and 2013. A neck dissection of a minimum of 10 LNs was required. Multivariable models were constructed to assess the association between the number of metastatic LNs and survival, adjusting for factors such as nodal size, laterality, extranodal extension, margin status, and adjuvant treatment...

BACKGROUND: Extranodal NK/T-cell lymphoma (ENKTCL) reports from sub-Saharan Africa (SSA) are remarkably rare, despite early childhood acquisition and high prevalence of the causative infectious agent, Epstein-Barr virus (EBV), and frequent occurrence of other lymphoproliferative disorders causally associated with EBV. CASE PRESENTATIONS: At a national teaching hospital in Malawi, three patients of African descent were seen with ENKTCL between 2013 and 2014. Patients were aged between 29 and 60 years, two with craniofacial involvement and one with a primary abdominal tumor, and all were HIV-negative...

BACKGROUND: Extranodal natural killer/T-cell lymphoma (ENKTL) usually presents as a localized disease in the nasal cavity; extension to the male genitourinary system is very rare and has been characterized only recently. Most cases present with predominantly extranodal involvement, advanced stage disease, highly aggressive course, and strong association with Epstein-Barr virus (EBV). While metastasis is common in ENKTLs, the penis is rarely involved in both nasal and non-nasal ENKTLs and only one report was published to date...

BACKGROUND: Current guidelines advocate no prophylactic dissection of the lateral neck compartment for papillary thyroid carcinoma (PTC) without clinical evidence of lateral neck metastasis (cN1b). However, lateral neck recurrence can affect patient treatment outcomes and quality of life. Therefore, this study examined the risk factors for lateral neck recurrence after the definitive treatment of PTC without cN1b. METHODS: The study enrolled 1928 consecutive patients who underwent total thyroidectomy between 2006 and 2012 for PTC without cN1b...
