Primary liver cancer's likelihood of metastasis depends on its pathological staging. If detected in the middle or late stages, it is more likely to metastasize. The most common sites of metastasis for primary liver cancer include intrahepatic and nearby digestive organs, such as the gastrointestinal tract and the peritoneum. Additionally, primary liver cancer can also spread through the bloodstream and the lymphatic system, reaching distant locations like the lungs, brain, and bones. If primary liver cancer cannot be surgically treated, the treatment options are limited, and the survival time is generally short, with an average lifespan of about one to two years.
