Metastatic tumors in the liver are 20 times more common than primary liver tumors (tumors that originate in the liver(. In 50% of all cases the primary tumor is of the gastrointestinal tract; other common sites include the breast, ovaries, bronchus and kidney. Patients with colorectal cancer may also develop liver metastases. [1]
Colon cancer with extensive metastases to the liver. Colorectal cancer diagnosis is performed by sampling areas of the colon suspicious for possible tumor development, typically during colonoscopy or sigmoidoscopy, depending on the location of the lesion. [20]
Sirtex targets metastatic colorectal cancer (mCRC) via SIR-Sphere microspheres. It has been thought that in 30-40% of individuals with severe illness, the liver is the only site of dissemination. At presentation, 20-25% of patients will have clinically identifiable liver metastases , and up to 50% of all patients develop liver metastases ...
The tumor in the lung is then called metastatic breast cancer, not lung cancer. Metastasis is a key element in cancer staging systems such as the TNM staging system, where it represents the "M". In overall stage grouping, metastasis places a cancer in Stage IV. The possibilities of curative treatment are greatly reduced, or often entirely ...
Among colorectal cancer patients, 15 to 25% will have liver metastases already when the colorectal cancer is discovered, and another 25 to 50% will develop them in the three years after resection of their primary cancer. [2] Of patients who die from metastasised colorectal cancer, 20% have metastasis in the liver alone. [2]
Hepatic arterial infusion (HAI) is a medical procedure that delivers chemotherapy directly to the liver.The procedure, mostly used in combination with systemic chemotherapy, plays a role in the treatment of liver metastases in patients with colorectal cancer (CRC). [1]
Most cases are metastases from other tumors, frequently of the GI tract (like colon cancer, carcinoid tumors mainly of the appendix, etc.), but also from breast cancer, ovarian cancer, lung cancer, renal cancer, prostate cancer, etc. The most frequent, malignant, primary liver cancer is hepatocellular carcinoma. [13]
The mechanism of this malignant cancer is still unclear; however, it has been found that a colon carcinoma cell known as HCC2998 causes an increase in differentiated tumor production. The reason for this increase is due to active PI3K that are converted to a SRCC-like cells.
