A 77-year-old male client with a diagnosis of stomach cancer has been found to have metastases in his liver. The client and his family are surprised at this turn of events, stating that they do not see how he could have developed cancer in his liver. Which of the following facts would underlie the reply that the care team provides?

Complete question: A 77-year-old male client with a diagnosis of stomach cancer has been found to have metastases in his liver. The client and his family are surprised at this turn of events, stating that they do not see how he could have developed cancer in his liver. Which of the following facts would underlie the reply that the care team provides?

A) The parenchymal tissue of the liver is particularly susceptible to secondary malignancies.

B) The portal circulatory system brings venous blood from the GI tract into the liver.

C) Hepatic stromal tissue shares characteristics with cancerous cells, including lack of anchorage dependence

D) The proximity of the liver to the stomach allows for direct spread of cancerous cells due to a lack of contact inhibition.

Answer: (B) The portal circulatory system brings venous blood from the GI tract into the liver.

Explanation: liver metastasis is a cancerous tumor that has spread to the liver from a cancer that started in another place in the body.

Due to aggressive tendencies of cancer cells, they often invade other part of the body. Cancer cells usually initiate invasion to other parts of the body by floating in the blood stream and establish replication in a new area.

The liver is highly prone to metastatis because of its rich blood supply and other bodily fluids that enhances cell growth.

However, Gastro-instestinal (GI) tract through the blood capillaries drains blood directly to the liver which makes the tendency of spread of cancer to the liver very high.
