What is peritoneal metastasis?

What is peritoneal metastasis?

Metastasis occurs when cancer spreads from its original site to other parts of the body. Peritoneal metastases refer to cancer that has spread to the peritoneum from other organs. When cancer spreads from other organs, it is considered advanced and denote Stage IV disease in most cases.

What is cholangiocarcinoma with metastasis?

Metastatic Cholangiocarcinoma (Stage IV) is an advanced stage of cancer and is examined in two groups: The first group is when the tumor has spread to the main blood vessel and lymph nodes.

What is carcinoma peritoneal?

Peritoneal carcinomatosis is a rare type of cancer that can develop when gastrointestinal or gynecologic cancers spread. That can cause tumors to grow in the peritoneum, the thin layer of tissue that lines the abdomen and covers most of the abdominal organs.

How long can you live with cholangiocarcinoma?

Cholangiocarcinomas arise from the epithelial cells of intrahepatic and extrahepatic bile ducts. They generally have a very poor prognosis. Many studies report a dismal median survival of approximately 6 months.

What is life expectancy peritoneal carcinomatosis?

The primary peritoneal cancer has a survival rate varying from 11-17 months. [70] In secondary peritoneal cancer, the median survival is six months in accordance with the stage of cancer (5-10 months for stages 0, I, and II, and 2-3.9 months for stage III-IV).

What is Stage 4 intrahepatic cholangiocarcinoma?

Stage 4A: The cancer is growing and has spread to the main blood vessel and the lymph nodes but not distant sites. Stage 4B: The cancer has either spread to lymph nodes away from the tumor or it has spread to distant sites.

What is the survival rate of peritoneal carcinomatosis?

Median overall survival with CRS/HIPEC has been reported to range from 22 to 63 months with a 5-year survival of 40-51% in selected patients [13, 15, 16].

What does peritoneal mean in medical terms?

Listen to pronunciation. (PAYR-ih-toh-NEE-ul KA-vuh-tee) The space within the abdomen that contains the intestines, the stomach, and the liver. It is bound by thin membranes.

What is cholangiocarcinoma?

This condition, also known as bile duct cancer, is an uncommon form of cancer that occurs mostly in people older than age 50, though it can occur at any age. Doctors divide cholangiocarcinoma into different types based on where the cancer occurs in the bile ducts:

What are peritoneal metastases?

Peritoneal metastases refer to cancer that has spread to the peritoneum from other organs. When cancer spreads from other organs, it is considered advanced and denote Stage IV disease in most cases. Cancers that develop from the peritoneum itself, such as primary peritoneal cancer or peritoneal mesothelioma, are very rare. Who is at risk?

What is peritoneal carcinomatosis?

Peritoneal metastases are a relatively common location for metastases, particularly from tumors of the abdomen and pelvis, that generally imply a poor prognosis, often with a significant impact on palliation 1. If peritoneal metastases are of an epithelial origin (as most are) and extensive, the term peritoneal carcinomatosis may also be used.

What is the differential diagnosis for cholangiocarcinoma?

Differential diagnosis depends on whether the tumor is intrahepatic or extrahepatic and on the growth pattern. For an intrahepatic mass-forming cholangiocarcinoma consider: liver metastases central necrosis (high T2 signal) is more common. hepatocellular carcinoma (HCC) tumor thrombus more common.
