Colorectal cancer combined with liver metastasis is advanced stage, and the specific survival period varies from person to person. Some studies claim that the 1-, 3- and 5-year survival rates of patients with colorectal cancer combined with liver metastasis are 77.7%, 29.1% and 12.8% in order.
Colorectal cancer is a malignant tumor originating from the colon, which is one of the common malignant tumors in the digestive system with a poor prognosis. Liver is the most important target organ for hematogenous metastasis of colorectal cancer, and liver metastasis of colorectal cancer is one of the focuses and difficulties in colorectal cancer treatment.
Some studies claim that about 15%~25% of colorectal cancer patients are combined with liver metastasis at the time of diagnosis, and another 15%~25% of patients will develop liver metastasis after radical resection of colorectal cancer primary foci, and the vast majority of them (80%~90%) are unable to obtain radical resection of liver metastasis initially.
Liver metastasis is also the leading cause of death in patients with colorectal cancer. The median survival of patients with untreated liver metastases is only 6.9 months, and the 5-year survival rate of patients who cannot be resected is less than 5%, whereas patients with liver metastases that can be completely resected have a median survival of 35 months, and the 5-year survival rate can be up to 30%-57%.
There are also studies claiming that the 1, 3 and 5-year survival rates of patients with colorectal cancer combined with liver metastases are 77.7%, 29.1% and 12.8% in that order.
Early detection, early diagnosis and early treatment are the keys to prolong patients’ survival. It is recommended to go to regular hospitals for consultation and treatment and follow the doctor’s instructions to avoid delaying the condition.
