Squamous cell carcinoma of the esophagus with cancer invasion beyond the muscularis mucosae is known to have lymph node metastasis and lymphatic or blood vessel invasion compared with intramucosal carcinoma. In submucosal and T2-3 carcinoma, lymph node and lymphatic/vascular involvement are shown more frequently, leading to a poor prognosis. Therefore, we examined proliferative activity of esop...

back ground: the aim of this study was to characterize the immunohistochemical expression of galectin 1, 3, and 9 in normal oral epithelium, oral squamous papilloma, and oral squamous cell carcinoma. materials and methods: immunohistochemical staining for galectins 1, 3, and 9 was evaluated in 8 samples of normal oral squamous epithelium, 15 samples of oral squamous papilloma, and 41 samples of...

the aim of this study is to determine whether there is a role of podoplanin and glutathione s-transferases t1 (gst-t1) expression in laryngeal squamous cell carcinoma. the study was completed with 33 patients and gene expression analysis was performed by qrt–pcr. the podoplanin and gst-t1 expression patterns were analyzed to determine their correlation with clinicopathologic parameters of laryn...

Basaloid squamous cell carcinoma of the esophagus is very rare. Further, polypoid type of esophageal cancer is also rare. We have recently treated a case of basaloid squamous cell carcinoma which presented as a 1.3-cm esophageal polyp. A 48-year-old woman was referred to our hospital because of a polypoid mass at 36 cm distance from the upper incisor on endoscopic examination, and the result of...

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 pres...

conclusions according to the low prevalence of hcmv in oscc, it seems that this virus plays a minor role in this kind of cancer at least in southeast of iran. more comprehensive studies are needed to investigate the oncomodulatory effect of this virus on oscc. results the mean age of the patients (66.7% female and 33.3% male) was 58.6 years. only three cases (6.3%) of the grade i, oscc biopsies...

background:non-melanoma skin cancer (nmsc), the most prevalent types being squamous cell carcinoma (scc) and basal cell carcinoma (bcc), is the most common type of malignancy in human beings. these neoplasms are more frequent in the elderly and fair skinned people and mainly occur on sun-exposed sites of the body. ultraviolet b (uvb) has a well-known effect in induction and promotion of growth ...

abstract background and aim: oral cancer is one of the most common cancers of the head and neck. considering the high prevalence and mortality percentage of oral cancer and the significant advances in immunology and identification of different cytokines, the aim of the present study was to compare the concentration of il8 in saliva of patients with oral squamous cell carcinoma (oscc) and health...

squamous cell carcinoma, a cancer of keratinocytes origin, mostly involves sun-exposed areas of the skin. to study the pathologic and demographic features of this disease, records of 395 patients of squamous cell carcinoma of skin and lip were reviewed. most of the patients (83%) aged 40 years or more at the time of diagnosis. respectively, 74.4% and 75.8% of cases with skin and lower lip carci...

stenosis, more than 10 cm of the esophagogastric junction. The biopsy diagnosed esophageal squamous carcinoma and gastric adenocarcinoma. CT of chest, abdomen and pelvis dismissed pleural effusion or chest lymphnodes. Showed concentric thickening of the lower third of the esophagus, in gastroesophageal junction, antrum and lymph node along the lesser gastric curvature . Liver was normal in size...
