What is mucin secreting adenocarcinoma?
Purpose: Mucinous adenocarcinoma is one of the histological subtypes of colorectal cancer. Mucinous colorectal adenocarcinomas comprise approximately 1 to 6 percent of all colorectal epithelial cancers. Frequently are more advanced at diagnosis and have a poorer prognosis than nonmucinous colorectal adenocarcinomas.
What is the treatment for mucinous adenocarcinoma?
Chemotherapies including the FOLFOX-4, XELOX (capecitabine and oxaliplatin), and FOLFIRI (folinic acid, fluorouracil and irinotecan) regimen are considered as regular treatment options for mucinous colorectal adenocarcinoma patients.
What is adenocarcinoma with mucinous features?
Mucinous adenocarcinoma is defined as having > 50 % tumor glands composed of extracellular mucin whereas adenocarcinoma with mucinous features entails < 50 % of tumor volume. They tend to occur in younger patients and are found in the proximal colon.
What kind of cancer is mucinous adenocarcinoma of colon?

How are mucin producing cells produced in adenomas?
Frequently, well differentiated mucin producing cells will pile up in adenomas, forming lumens, technically appearing cribriform This is unusual in the absence of cribriform architecture, but can occur Invasion with a desmoplastic response confined to the lamina propria including muscularis mucosae
