e-cadherin is among tumor suppressor genes which mostly subjects to the down-regulation in squamous cell carcinoma of esophagus (scce). the gene is tightly associated with the tumor invasion and metastasis in multiple human cancers, especially scce. cpg islands’ methylation in the promoter region of e-cadherin is among the mechanisms that have been suggested for the e-cadherin silencing, howeve...
Background: It is rare to find squamous metaplasia in the thyroid gland. Its existence is usually seen in association with a pathological lesion such as mucoepidermoid carcinoma, squamous cell carcinoma and diffuse sclerosing variant of papillary thyroid carcinoma. In most cases the squamous cells are few in number and squamous metaplasia is focal and small in size. Extensive squamous metaplasi...
Background: The aim of this retrospective study was to evaluate the therapeutic outcomes and organ preservation in patients with squamous cell carcinoma of the buccal mucosa treated with radiotherapy and retrograde superselective intra-arterial chemotherapy. Materials and Methods: Between April 2006 and March 2016, 28 patients (3 with stage II; 8 with stage III; and 17 with stage IV) with squam...
Objective(s) Matrix metalloproteinases comprise a family of enzyme that is able to degrade components of extra cellular matrix. There are single nucleotide polymorphisms in the promoter regions of several genes with ability to influence cancer susceptibility. The aim of this study was to analyses association between MMP2 and MMP9 promoter polymorphisms and head and neck squamous cell carcinoma...
Introduction: Squamous cell carcinoma (SCC) is the most common head and neck malignancy. Smoking, alcohol consumption, viral infections, exposure, oral hygiene, and dietary, genetic, and occupational factors are the most important etiologic factors. The aim of this study was determining the incidence of etiologic factors in head and neck SCC. Materials and Methods: This is a cross-sectiona...
Background: Oral cancer is among the 10 most common cancers worldwide with an increasing global incidence. Compromised antioxidant defense system plays a role in occurrence of cancer. This study evaluated the salivary antioxidant level of oral cancer patients compared to a control group. Patients and Methods: This case-control study was conducted on 22 oral squamous cell carcinoma patients pre...
Introduction Presence of two primary malignancies is rare and occurs in 3-5% of the cancer patients. As per our extensive internet research, this is the only reported case of a synchronous sino-nasal embryonal rhabdomyosarcoma with squamous cell carcinoma-tongue. The case report is important because of the rare diagnosis and the challenge we faced in the diagnosis and treatment of the pat...
objectives: presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (scc). this study was designed to assess the diagnostic accuracy of computed tomography (ct) scan for detection of cervical lymph node metastasis in oral scc in comparison with histopathological analysis after neck dissection methods: in th...
background: this study evaluated the relation between telomere length in lymph node (ln) and prognosis of esophageal squamous cell carcinoma (escc). materials and methods: lns collected from 50 patients were assessed by pathological examination and quantitative reverse transcription polymerase chain reaction (qrt-pcr), which was used for detecting telomere length. the relation between clinical...
هیدرآدنیت چرکی، یک بیماری عودکننده است که باعث درگیری غدد عرق پوست عمدتاً در نواحی چین دار بدن می گردد. سیر بالینی این بیماری به میزان زیادی متغیر است. در موارد خفیف، به صورت ندول های منفرد عود کننده دیده می شود ولی در موارد شدید، با التهاب مزمن و ایجاد آبسه و اسکار همراه بوده و بندرت به اسکواموس سل کارسینوما تبدیل می شود. در حالی که عوامل ژنتیکی، هورمون ها و عفونت در ایجاد بیماری نقش دارند، پات...
