Head and neck squamous cell carcinoma in people living with HIV in France.
2018
Abstract Objectives Head and neck squamous cell carcinoma (HNSCC), mainly due to smoking, is one of the leading causes of cancer deaths. However, an increasing number of tumors – especially oropharyngeal cancer – are reported in non-smokers in association with the human papillomavirus (HPV). As HIV-infected individuals are particularly at risk of HPV-related disease, we aimed to describe the burden of HNSCC in this population. Methods Retrospective chart review of patients from HIV clinics diagnosed with HNSCC between 2004 and 2014. Case patients were defined using the International Classification of Disease for Oncology (3rd edition). Age at HIV diagnosis and time from HIV diagnosis to HNS…
[Use of imaging criteria to identify cervical metastases using CT scans in head and neck tumours].
2008
Abstract Objective To assess the diagnostic certainty of CT images to identify regional spread of head and neck tumours. Patients and method A CT study was performed on 86 patients with neoplasms in the larynx and/or pharynx. After this, surgical dissection was performed for 142 neck sides. In the imaging study the following parameters were considered for all patients before suspecting malignant nodes: size of adenopathy bigger than 10–11 mm, irregular borders, central necrosis, spherical shape, capsular enhancement, and presence of groups with 3 or more lymphadenopathies. Results 48.5% of dissections were N+. Sensitivity and specificity for physical examination were 59% and 82%, respective…
Synthesis and In Vitro Evaluation of Defined HPMA Folate Conjugates: Influence of Aggregation on Folate Receptor (FR) Mediated Cellular Uptake
2010
In this article we report the synthesis and in vitro evaluation of well-defined, folate functionalized and fluorescently labeled polymers based on the clinically approved N-(2-hydroxypropyl)-methacrylamide (HPMA). The polymers were prepared applying the RAFT polymerization method as well as the reactive ester approach. The molecular weights of the polymers synthesized were around 15 and 30 kDa. The total content of conjugated folate varied from 0, 5, and 10 mol %. The cellular uptake of these polymers was investigated in the folate receptor (FR)-positive human nasopharyngeal epidermal carcinoma (KB-3-1) and FR-negative human lung epithelial carcinoma (A549) cancer cell lines. In FR-positive…
Interleukin-10 and interleukin-18 promoter polymorphisms in an Italian cohort of patients with undifferentiated carcinoma of nasopharyngeal type.
2004
Purpose: Cytokines such as IL-10 and IL-18 seem to be involved in the inflammatory response of undifferentiated carcinoma of nasopharyngeal type (UCNT). The aim of this study was to evaluate the correlation between functional single nucleotide polymorphisms (SNPs) in the promoter region of IL-10 and IL-18 genes and the virological and clinical characteristics in a large case series of Caucasian patients suffering from UCNT, a tumor regularly associated with the Epstein Barr Virus (EBV). Methods: Eighty-nine patients with histologically confirmed UCNT and 130 healthy donors were included in our study. DNA was examined for the polymorphisms of IL-10 gene at positions –1082, −819, −592 by dire…
Solitary splenic metastasis from nasopharyngeal carcinoma: a case report and systematic review of the literature
2016
Background: Solitary splenic metastases are a rare occurrence, and the nasopharyngeal carcinoma represents one of the most uncommon primary sources. The present study aimed to describe a rare case of a solitary single splenic metastasis from nasopharyngeal carcinoma and to assess the number of cases of isolated nasopharyngeal carcinoma metastases to the spleen reported in the literature. Main body: We describe the case of a 56-year-old man with a history of nasopharyngeal carcinoma and complete remission after chemo-radiotherapy. Three months after complete remission, positron emission tomography/ computed tomography scan revealed a hypermetabolic splenic lesion without increased metabolic …
Clinical-pathological and sociodemographic factors associated with the distant metastasis and overall survival of oral cavity and oropharynx squamous…
2020
Background The objective of this study was to evaluate the influence of clinical-pathological and sociodemographic factors on the prevalence of distant metastasis (DM) and overall survival in patients with oral cavity and oropharynx squamous cell carcinoma (OOSCC). Material and Methods Cross-sectional study based on the records of 404 OOSCC patients evaluated for DM, covering the period 2000-2014. We analysed the influence of age, sex, level of schooling, primary tumor subsite, treatment, marital status, family history of cancer, history of smoking and alcohol consumption, type of health care coverage (private vs. public) and overall survival. Findings were submitted to Fisher’s exact test,…
Olfaction in chemotherapy for head and neck malignancies
2015
Abstract Objective Systemic chemotherapy for different malignancies occurs alongside various side effects, including reduced sensory function. To date, little is known about the effect of chemotherapeutic agents on olfaction. The aim of this study was to provide new data about changes in sense of smell during chemotherapy among patients with advanced squamous cell carcinomas of the head and neck region. Methods In a prospective, controlled cohort study of patients undergoing up to three courses of chemotherapy (cis- or carboplatin, 5-fluorouracil and docetaxel), olfaction was evaluated prior to and directly following completing a cycle, as well as 3 weeks later with the beginning of the nex…
Expression of p53 Protein and Tumor Angiogenesis as Prognostic Factors in Nasopharyngeal Carcinoma Patients.
2002
The objective of this study was to evaluate the possible prognostic significance of p53 protein overexpression and tumor angiogenesis (TA) in nasopharyngeal carcinoma (NPC) patients, together with other clinicopathological variables. Forty-two NPC patients were evaluated in relation to survival. Nuclear p53 overexpression in neoplastic and endothelial cells was detected by immunohistochemistry (IHC) with the monoclonal antibody DO-7 and the polyclonal antibody against factor VIII-related antigen, respectively. Thereafter, we evaluated p53 cases in order to determine their nuclear immunoreactivity from negative (-) to positive (+, ++, +++). In addition, microvessels were counted in the most …
Incidence of childhood cancer of the head and neck in Germany.
2007
Background: Only very limited data are available in the literature on the incidence of childhood cancer of the head and neck worldwide. Methods: Based on data obtained from the national German Childhood Cancer Registry, a total of 370 malignancies of the head and neck in children under the age of 15 (199 boys and 171 girls), which were reported to this institution between 1994 and 2003, were analysed in this study. Results: The overall incidence of malignancies of specific sites of the head and neck in Germany is 4.48 per 100000 children. The most frequently observed entities, representing primary tumours, are soft tissue sarcomas (0.39/100000), lymphomas (0.09/100000) and thyroid carcinoma…
Epidemiology and survival outcomes of lip, oral cavity, and oropharyngeal squamous cell carcinoma in a southeast Brazilian population.
2021
Lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC) represent a major health problem in the global scenario. In South America, the highest incidence rates are seen in Brazil. Therefore, the epidemiological and clinical profile and survival outcomes of lip, oral cavity, and oropharyngeal SCC was studied in São Paulo State, Brazil. The clinicopathological data of 12,099 patients with lip, oral cavity, and oropharyngeal SCC were obtained from hospital cancer registries of the Fundação Oncocentro de São Paulo, Brazil (2010?2015). Survival rates and other analyses were performed using SPSS software. A clear male predominance was observed, particularly for patients with oropharyngea…
