OBJECTIVES: The age of oral and pharyngeal cancer patients has reportedly decreased over the last decade, but most of the peer-reviewed literature regarding oral and pharyngeal cancer in individuals 0-19years of age (Y) is limited to specific tumor sites and/or types, or a small number of cases. Our aim is to characterize oral, salivary gland and pharyngeal cancer (OSPC) in 0-19Y in order to improve knowledge of the disease in young individuals. METHODS: Data on OSPC between 1970 and 2011 was taken from the Israel National Cancer Registry, and included patient age, gender, tumor site and tumor type...

Introduction: Cancer is a leading cause of morbidity and mortality in the United States and results in a high economic burden. Objective: To estimate age-standardized mortality rates by US county from 29 cancers. Design and Setting: Deidentified death records from the National Center for Health Statistics (NCHS) and population counts from the Census Bureau, the NCHS, and the Human Mortality Database from 1980 to 2014 were used. Validated small area estimation models were used to estimate county-level mortality rates from 29 cancers: lip and oral cavity; nasopharynx; other pharynx; esophageal; stomach; colon and rectum; liver; gallbladder and biliary; pancreatic; larynx; tracheal, bronchus, and lung; malignant skin melanoma; nonmelanoma skin cancer; breast; cervical; uterine; ovarian; prostate; testicular; kidney; bladder; brain and nervous system; thyroid; mesothelioma; Hodgkin lymphoma; non-Hodgkin lymphoma; multiple myeloma; leukemia; and all other cancers combined...

A significant fraction of nasopharyngeal and sinonasal tumors are associated with Epstein-Barr virus (EBV) or human papillomavirus (HPV). Nasopharyngeal carcinoma (NPC) and extranodal NK/T-cell lymphoma harbor EBV in practically all cases, although a small proportion of cases of the former harbor HPV. Sinonasal inverted papillomas harbor HPV in about 25% of cases. Sinonasal squamous cell carcinomas harbor transcriptionally active HPV in about 20% of cases, and limited data suggest that this subset has a better prognosis than the HPV-negative subset...

NK/T-cell lymphomas are a group of clonal proliferations of NK- or, rarely, T-cell types and have peculiar clinicopathologic features. Most common site of involvement is the upper aerodigestive tract (nasal cavity, nasopharynx, paranasal sinuses, and palate). Association of autoimmune paraneoplastic disorders with NK/T-cell lymphomas is not well studied. Our patient was diagnosed with NK/T-cell lymphoma stage IV with skin involvement and treated frontline with CHOEP regimen. While he was under treatment, two immune complications presented: anterior uveitis of autoimmune origin refractory to steroids and myositis in lower limbs muscles...

The parapharyngeal space extends from the nasopharynx to the oropharynx. It is bordered medially by the pharyngeal wall and the constrictor pharyngis muscles, and laterally by the mandible. One distinguishes between a pre- and a poststyloid space. Tumors of the parapharyngeal space are rare and represent less than 1 % of all head and neck neoplasms. Benign (70-80 %) as well as malignant (20-30 %) tumors arise from different structures of the parapharyngeal space, mainly from salivary glands and nerve structures...

Nasal type extranodal natural killer/T-cell lymphoma (ENKTL) is a rare lymphoma in the USA and Europe but endemic in East Asia and in areas of South and Central America. Clinically natural killer cell lymphomas are divided into three categories; nasal, non-nasal and aggressive lymphoma/leukemia subtypes. ENKTL, nasal type occurs in the nose and can extend to the upper aero-digestive tract as reported in this longitudinal case study. This is a longitudinal report of progress of a 14-year-old boy with ENKTL originating in the nasal cavity with subsequent extension and recurrence in the contralateral nose, nasopharynx, larynx and trachea presenting with varying degrees of respiratory problems and eventually, respiratory distress...

Extranodal natural killer/T-cell lymphoma (ENK/TCL) is most often in the nose or the nasopharynx but can present elsewhere. We report a rare case of ENK/TCL that presented as swelling of an upper eyelid without ocular involvement. A 76-year-old man visited our hospital with a swollen lesion of the left upper eyelid which had appeared 2 months earlier. A biopsy of the upper eyelid revealed slight perivascular and periadnexal infiltration of mononuclear cells with dermal edema. Treatment with oral prednisolone at a dosage of 20 mg/day decreased the eyelid swelling...

We utilized computerized record-linkage methods to link HIV and cancer databases with limited unique identifiers in Pune, India, to determine feasibility of linkage and obtain preliminary estimates of cancer risk in persons living with HIV (PLHIV) as compared with the general population.Records of 32,575 PLHIV were linked to 31,754 Pune Cancer Registry records (1996-2008) using a probabilistic-matching algorithm. Cancer risk was estimated by calculating standardized incidence ratios (SIRs) in the early (4-27 months after HIV registration), late (28-60 months), and overall (4-60 months) incidence periods...

We reviewed 87 epidemiological studies relating environmental tobacco smoke (ETS) exposure to risk of cancer other than lung or breast in never smoking adults. This updates a 2002 review which also considered breast cancer. Meta-analysis showed no significant relationship with ETS for nasopharynx cancer, head and neck cancer, various digestive cancers (stomach, rectum, colorectal, liver, pancreas), or cancers of endometrium, ovary, bladder and brain. For some cancers (including oesophagus, colon, gall bladder and lymphoma) more limited data did not suggest a relationship...

BACKGROUND: Hepatitis C virus (HCV) infection is associated with hepatocellular carcinoma and non-Hodgkin's lymphoma. In 2009, MD Anderson established the first US clinic for treating HCV-infected cancer patients, where we observed an unexpectedly large number of patients with head and neck cancers (HNCs). We sought to determine whether HCV is associated with HNCs. METHODS: In this case-control study, medical records of cancer patients tested for HCV antibodies at our center from 2004 through 2014 were identified...

Extranodal natural killer/T-cell lymphoma (ENKL) of the nasal type is a rare, clinically aggressive disease. ENKL of the nasal type is often localized in the upper aerodigestive tract, including the nasal cavity, nasopharynx, paranasal sinuses, tonsils, hypopharynx and larynx, and usually presents as stage I/II. Extranasal involvement can occur, and a common site of extranasal involvement or metastatic disease includes the skin. Identifying skin metastases is important for the appropriate staging and treatment...

EBV causes B lymphomas and undifferentiated nasopharyngeal carcinoma (NPC). Although the mechanisms by which EBV infects B lymphocytes have been extensively studied, investigation of the mechanisms by which EBV infects nasopharyngeal epithelial cells (NPECs) has only recently been enabled by the successful growth of B lymphoma Mo-MLV insertion region 1 homolog (BMI1)-immortalized NPECs in vitro and the discovery that neuropilin 1 expression positively affects EBV glycoprotein B (gB)-mediated infection and tyrosine kinase activations in enhancing EBV infection of BMI1-immortalized NPECs...

We analyzed the histopathological characteristics of lymphomas biopsied from the upper aerodigestive tract between 2000 and 2014 at the National Cancer Center Hospital in Japan. Of a total of 309 consecutive cases, the following incidences were observed: mature B-cell neoplasms, 77% (n = 239); mature T- and NK-cell neoplasms, 20% (n = 63); classical Hodgkin lymphomas, 0.7% (n = 2); and lymphoblastic lymphomas, 2% (n = 5). Lymphomas were most frequently (57%) detected in the oropharynx. The majority of cases (89%) were mature B-cell neoplasms (diffuse large B-cell lymphoma, 60%; follicular lymphoma, 10%), and 10% of cases were mature T-cell neoplasms...
