Esophageal Squamous Cell Carcinoma

A squamous cell carcinomas arising from the esophagus. It is associated with a long history of tobacco and alcohol abuse and is exceedingly rare before the age of 30. The median age is around 65 in both males and females. It is located mostly in the middle and lower third of the esophagus. Grossly, polypoid, ulcerated, plaque-like and occult lesions have been described. The microscopic features are the same as in other squamous cell carcinomas. Any degree of differentiation may occur, and variation within a single tumor is common. The prognosis is poor. [from NCI]

Carcinoma

A malignant tumor arising from epithelial cells. Carcinomas that arise from glandular epithelium are called adenocarcinomas, those that arise from squamous epithelium are called squamous cell carcinomas, and those that arise from transitional epithelium are called transitional cell carcinomas (NCI Thesaurus). [from HPO]

Malignant tumor of esophagus

Esophageal cancer, particularly esophageal squamous cell carcinoma (ESCC), is one of the most common cancers worldwide. Both environmental and genetic risk factors play a role in the pathogenesis of the disorder. In Europe and North America, heavy smoking, alcohol consumption, and increased body mass index (BMI) are the main environmental risk factors. In contrast, the particularly high incidence of ESCC in some areas of China, central Asia, and southern Africa is associated with nutritional deficiencies, high intake of nitrosamine-rich or pickled vegetables, and low socioeconomic status; smoking, alcohol consumption, and BMI play a lesser role in these populations. There is a tendency for familial aggregation of ESCC in high-risk geographic areas, suggesting a genetic component to increased susceptibility. Gastric cardia adenocarcinoma is another common type of cancer in China that shows similarities to ESCC in terms of geographic distribution and environmental risk factors (summary by Wang et al., 2010 and Abnet et al., 2010). Genetic Heterogeneity of Susceptibility to Esophageal Cancer See a variant in the ADH1B gene (103720.0001) for discussion of a possible genetic association with protection against squamous cell aerodigestive tract cancer, including esophageal cancer, in alcohol drinkers. See a variant in the ALDH2 gene (100650.0001) for discussion of a possible genetic association with increased risk for esophageal cancer in alcohol drinkers due to interaction between variants in the ADH1B and ALDH2 genes. See the S100A14 gene (607986) on chromosome 1q21 for a discussion of a possible association between variation in that gene and susceptibility to esophageal squamous cell carcinoma among smokers. Genetic Heterogeneity of Somatic Mutations in Esophageal Cancer Somatic mutations in several different genes have been found in esophageal cancer tissue. These genes include TP53 (191170), CDKN2A (600160), DEC1 (604767), DCC (120470), DLEC1 (604050), TGFBR2 (190182), LZTS1 (606551), RNF6 (604242), WWOX (605131), APC (611731), and RUNX3 (600210). [from OMIM]

Ameliorated by

Weakened or thinned. Attenuated strains of disease-causing bacteria and viruses are often used as vaccines. The weakened strains are used as vaccines because they stimulate a protective immune response while causing no disease or only mild disease in the person receiving the vaccine. [from NCI_NCI-GLOSS]
