Objective: To explore the value of Positron-Emission Tomography/Computed Tomography (PET/CT) in the prognosis of extranodal NK/T cell lymphoma. Methods: The patients of NK/T cell lymphoma diagnosed from January 2007 to July 2016 in Department of Pathology of Beijing Tongren Hospital were enrolled in this study. Seventy-two in-hospital patients were examined on the invasion of adjecent tissue or organ by PET/CT. The PET/CT results were analyzed retrospectively. Kaplan-Meier method was used to analyze the prognostic value of the positive results by PET/CT on overall survival (OS)...

BACKGROUND: The incidence of pediatric head and neck cancer (PHNC) is increasing worldwide, especially when compared with childhood cancer in general. However, there is still a lack of knowledge about the demographic profile of such patients across the globe. Therefore, the aim of this study was to describe demographic, topographic and histopathological features of pediatric head and neck cancer patients from a single Brazilian institution. METHODS: Medical records were retrospectively reviewed for all cancer cases diagnosed from 1986 to 2016 affecting patients aged 19-years and younger...

Purpose: There are few reports on survival rate analysis from hospital-based cancer registries (HBCR) in China, although the National Center of Cancer Registry of China has launched such an effort with the mission to expand the scope of registration and follow-up. Our study aimed to evaluate survival and outcomes of cancer patients from a HBCR in eastern China. Methods: Active and passive follow-up methods were used to obtain information on survival status for all patients from Qidong City and Haimen City in the databases of our hospital-based registrations from 2002 to 2014...

Plasmacytoma of the skull-base is a rare entity. Differential diagnosis includes chordoma, osteosarcoma, carcinoma nasopharynx, meningioma, metastatic carcinoma, lymphoma, and multiple myeloma. Accurate and precise diagnosis is extremely important for plasmacytoma of the skull-base as its treatment and prognosis is different from other skull-base lesions. A 41-year-old man presented with concerns of headache, diplopia, and left eye strabismus. A magnetic resonance image (MRI) of his brain showed a large expansile mass measuring 51 mm involving the clivus and central skull-base...

BACKGROUND: The sequential occurrence of the 2 malignancies development of nasopharyngeal carcinoma (NPC) and lymphoma is extremely rare and their coexistence raises the question of a common etiologic factor. CLINICAL FINDINGS/CLINICAL CONCERNS: A 71-year-old previously healthy man presented with diffuse large B-cell lymphoma (BCL) followed by NPC almost 2 years later with Epstein-Barr virus (EBV) positive. DIAGNOSIS: Endoscopic examination characterized a fixed, hard and nontender mass in the nasopharynx and biopsies were done...

We aimed to characterize the trends and projections of cancer mortalities in Yangpu, an industry restructuring district of Shanghai, China. With high-quality data from the death registration system, the authors analyzed the trends in cancer mortalities during 1974-2014 and their relationship with pollution control and socioeconomic improvements. Cancer burden was projected into 2029. During 1974-2014, cancer death accounted for 28.80% of all-cause death. The 5 leading causes of cancer death were cancers of the lung & bronchus, stomach, liver, colon & rectum, and esophagus...

BACKGROUND: Cancer disparities within and across populations provide insight into the influence of lifestyle, environment, and genetic factors on cancer risk. METHODS: Guam cancer incidence and mortality were compared to that of Hawaii using data from their respective population-based, central cancer registries. RESULTS: In 2009-2013, overall cancer incidence was substantially lower in Guam than in Hawaii for both sexes while overall cancer mortality was higher for Guam males...

INTRODUCTION: Extranodal natural killer/T (NK/T) cell lymphoma, nasal type (ENKTL) represents a rare subtype of T-cell lymphomas with aggressive clinical behavior according to WHO 2016 classification. AIM: ENKTL has distinctive geographic distribution with higher incidence in Asia and Latin America (10% of all non-Hodgkin lymphoma cases), than in Europe and North America (<1%). ENKTL tipically origins from nasopharynx and upper aerodigestive tract. Anthracycline-based chemotherapy regimens are largely ineffective in the treatment of ENKTL...

Cancer is a serious public health issue and the leading cause of death around the world. This article aimed to estimate the cancer incidence and the trend in standardized cancer incidence in Shenzhen, Guangdong province, South China during 2001-2015 by analyzing the cancer data of the population-based cancer registry in Shenzhen. Data were collected from the cancer registry in Shenzhen, which was conducted during 2001-2015. In this registry, the crude incidence rates, age-specific incidence rates, age-standardized incidence rates and cumulative incidence rates were calculated in every five years...

Objective: To investigate the pathological features and clinical manifestations of mucosa-associated lymphoid tissue (MALT) lymphoma in children and adolescents. Methods: Five cases of MALT lymphoma in children were investigated by morphology and immunophenotyping along with clinical follow-up. Results: Five cases of MALT lymphoma occurred in the antrum, orbit, parotid gland and nasopharynx. All patients had no B symptoms and only one patient showed a local mass with ulcer. One case presented with cervical lymph node enlargement, and 4 cases showed no evidence of lymphadenopathy...

RATIONALE: Lymphomas take up about 14% of all head-neck malignancies, out of which 97% are non-Hodgkin lymphomas (NHL). The clinical courses, treatment responses, and prognoses of NHLs vary with different subtypes and anatomic sites. In the Chinese population (including the Taiwanese), head-neck NHLs are often seen with the tonsils, nasal cavity, nasal sinus, and the nasopharynx. However, oral NHLs are relatively rare. Delay of diagnosis is also often seen in clinical practice. Thus, we present 4 cases with delayed diagnosis of oral maxillofacial NHLs and discuss their clinical manifestations so as to draw a clue that can remind the doctors to take biopsies in time...

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...

PURPOSE: This study aimed to determine the pathways of primary tumor invasion (PTI) and regional lymph node (LN) spread based on magnetic resonance imaging (MRI) in early-stage nasal NK/T-cell lymphoma (NKTCL), to improve clinical target volume (CTV) delineation and evaluate the prognostic value of locoregional extension patterns. METHODS AND MATERIALS: A total of 105 patients with newly diagnosed early-stage nasal NKTCL who underwent pretreatment MRI were retrospectively reviewed...

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...
