However, a recent increase in the use of computed tomography (CT) has enabled small adenocarcinoma detection on a screening basis, and many of these small adenocarcinomas are relatively dormant bronchioloalveolar carcinomas and have favorable outcome (3… Esophageal cancer can occur anywhere along the esophagus. Esophageal cancer is cancer that occurs in the esophagus — a long, hollow tube that runs from your throat to your stomach. 2020 Dec;405(8):1091-1099. doi: 10.1007/s00423-020-01990-0. Diagnostic algorithm for esophageal carcinoma of uncertain differentiation. Types. Esophageal adenocarcinomas have mutations in tumor protein p53 and mutations that activate receptor-associated tyrosine kinase, vascular endothelial growth factor, and cell cycle pathways, whereas esophageal squamous tumors have a distinct set of mutations. Squamous cell carcinoma is associated with black race, alcohol and smoking, while adenocarcinoma is related to higher body mass index, white race and Barrett’s esophagus. Patients with adenocarcinoma were known to result in poorer prognosis than those with squamous cell carcinoma (1,2). Mariette C, Taillier G, Van Seuningen I, Triboulet JP. 2020 Jan 7;2020:6520259. doi: 10.1155/2020/6520259. In the context of esophageal cancer, screening would aim to detect Barrett’s esophagus (BE) and dysplasia in squamous epithelium, which are precursor lesions to esophageal adenocarcinoma (EA) and esophageal squamous cell carcinoma (ESCC), respectively. We analyzed commonly used immunohistochemical markers (p63, cytokeratin 5/6, cytokeratin 7, CDX2, MUC2, and MUC5AC) and 2 new markers, anterior gradient homolog 2 and SOX2, in esophageal carcinomas to establish the best panel to distinguish these tumors. 1 Esophageal squamous cell carcinoma (ESCC) accounts for approximately 90% of the overall incidence of esophageal cancer, and China contributes nearly half of all esophageal cases worldwide. The groups with adenocarcinoma and SCC were comparable regarding age, postoperative 90‐day mortality (6.6% vs. 8.5%), infiltration of submucosa (74.5% vs. 80%), and rate of lymph node metastasis (17% vs. 16.6%). Anterior gradient homolog 2 was highly sensitive for adenocarcinoma and present in 68 of 69 of cases, but anterior gradient homolog 2 reactivity was also identified in 15 of 41 of squamous cell carcinomas, typically demonstrating focal reactivity in squamous cell carcinoma. • Adenocarcinoma arises from glands while squamous cell cancers arise from flat squamous cells. 2002;15(4):290-5. doi: 10.1046/j.1442-2050.2002.00272.x. Diagn Pathol. 2019 Nov 17;20(22):5781. doi: 10.3390/ijms20225781. USA.gov. • Adenocarcinoma may occur anywhere with glandular tissue while squamous cell carcinoma mostly occurs on the skin surface. 1983 Oct;198(4):531-40 More men than women get esophageal cancer.Esophageal cance… Additionally, 29% had squamous cell carcinoma and 71% had adenocarcinoma. The aim of the study was to identify the similarities and differences between SCC and ADC in terms of their clinical and histologic presentations and the oncologic results.

CONCLUSION: Epidemiological features are distinct for the histopathological types of esophageal cancer. Esophageal cancer is characterized by early and frequent metastasis. Epub 2019 Nov 15. Sensitivities and specificities were calculated for individual markers and select combinations using the morphological diagnosis as a gold standard.

SOX2 expression was present in 35 of 41 of squamous cell carcinomas but also in 24 of 69 of adenocarcinomas, frequently demonstrating extensive reactivity in adenocarcinomas. -, Br J Surg. Liver metastatic basaloid squamous cell carcinoma with negative expression of pancytokeratin: a case report and literature review. Some cases of esophageal adenocarcinoma also expressed nuclear SOX2 (F). SOX2 is highly expressed in squamous cell carcinomas of the gastrointestinal tract. There was a significant survival advantage for ADC patients with pT1, pN0, or stage I tumors (p < 0.050) and different independent prognostic factors than those with SCCs. Hum Pathol. doi: 10.1042/BSR20201727. Treatment may also be different for the 2 types. The SCC and ADC groups were composed of 624 and 118 patients, respectively. Histologically, there are two predominant types of primary esophageal cancers: squamous cell carcinoma and adenocarcinoma. • Adenocarcinoma can metastasize frequently while squamous cell cancers rarely … Comparison of the short-term and long-term outcomes of surgical treatment versus endoscopic treatment for early esophageal squamous cell neoplasia larger than 2 cm: a retrospective study.  |  Overall, the dual expression of both p63 and cytokeratin 5/6 was 99% specific and 98% sensitive for squamous cell carcinoma. A third type of esophageal cancer, called small cell carcinoma, is very rare. Primary gastric squamous cell carcinoma presenting as a large submucosal mass: A case report and literature review. Alexandrou A, Davis PA, Law S, Murthy S, Whooley BP, Wong J. Dis Esophagus. Esophageal adenocarcinoma (EAC) has received considerable attention in recent years because of its rapid increase in incidence. Log in Now. Neoadjuvant radiochemotherapy was proposed for patients with locally advanced tumors. Adenosquamous carcinoma (ASC) is thought to behave more aggressively than each of its counterparts. See this image and copyright information in PMC. It is estimated that 16,170 deaths (13,100 men and 3,070 women) from this disease will occur this year. Herein, we aimed to compare the molecular characteristics of three different gastroesophageal cancer types: esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), and gastric adenocarcinoma (GAC). 1995 Jan;109(1):130-8; discussion 139 2019 Jul;33(7):2304-2312. doi: 10.1007/s00464-018-6524-2.
