The types of duodenal cancer

Duodenal adenocarcinoma is originating from duodenal mucosa and most cases of this type are solitary, but some cases develop from adenoma cancerization.

Duodenal carcinoid is a malignant tumor starting from the enterochromaffin cell of intestine and mostly occurs as small tumor. It can present as a single tumor or multiple tumors in intestinal tract. As the tumor increases, the infiltrating symptoms develop.

Duodenal leiomyosarcoma is a tumor of muscular layer arising from muscularis mucosa or muscularis propria of duodenum or the vessel wall in intestinal wall.

Malignant lymphoma of duodenum is a cancer originating from the lymphatic tissues of duodenal wall, which is different from the secondary lesions caused by the encroachment of general malignant lymphoma on intestine.

As a rare cancer, duodenal cancer has an incidence of less than 1% in all malignant tumors. It tends to occur to the age range of 50-70 and the male patients are roughly more than the females.

What cause duodenal cancer?

Currently the cause of duodenal cancer is still unclear. But some materials in bile and pancreatic juice like lithocholic acid and other secondary bile acid may be the carcinogenic agent. Familial polyposis, benign epithelial tumor, villous adenoma or other diseases are possibly causing duodenal cancer. Apart from that, there are studies indicating duodenal ulcer or diverticular cancerization and heredity has something to do with duodenal cancer.
