What type of endoscopic surveillance is recommended in patients with tylosis? Patients with tylosis should begin endoscopic surveillance at the age of 30. Most cases of esophageal cancer in these patients have been noted in the distal esophagus, so attention should be focused in this area during the examination. Repeat endoscopy should not be conducted […]

What rare genetic disorder is associated with a high incidence of SCC of the esophagus? Tylosis is an uncommon autosomal dominant disorder that is distinguished by thickening of the skin (hyperkeratosis) on the palms and soles. The syndrome is associated with a 27% incidence of SCC of the esophagus. The average age at onset of

Clinical characteristics of patients who develop esophageal cancer after a caustic injury The mean age of onset is 35 to 51 years. The average interval between caustic injury and development of esophageal cancer is approximately 40 years. Cancers are located in the midesophagus.
Is there a link between caustic ingestion and the development of esophageal cancer? Yes. A caustic injury to the esophagus, most commonly after lye ingestion, appears to be associated with an increased risk of developing SCC of the esophagus. A history of caustic ingestion is present in 1% to 4% of patients with esophageal cancer.

Role of endoscopic cancer surveillance in patients with achalasia Currently, there is insufficient data to support routine endoscopic surveillance in patients with achalasia. Endoscopic surveillance in patients with achalasia has not been found to be cost effective but may be considered 15 years after the onset of symptoms. All surface abnormalities of esophagus identified during

Do patients with achalasia have an increased risk of esophageal cancer? Yes. Individuals with achalasia have as much as a thirty-threefold greater risk of developing SCC of the esophagus compared with the general population. On average, patients with achalasia will have had at least 15 years of symptoms prior to the diagnosis of esophageal cancer.

What is the principal role of endoscopic ultrasound (EUS) in evaluating patients with HGD? EUS can be used to exclude the presence of occult cancer, submucosal invasion, and malignant lymphadenopathy in patients with BE of HGD. This information is particularly important when determining the appropriate selection of patients if endoscopic management is considered. Routine application
