What should you know about synchronous liver metastases?

Synchronous liver metastases are cancer deposits in the liver found at the same time as the original cancer diagnosis. The liver deposits began in another organ, so they are treated according to the original cancer type, not as a new primary liver cancer. This finding does not by itself determine which treatment is suitable; the number, size and position of deposits, the primary tumour, overall health and test results all influence the plan.

“Synchronous” describes timing: liver metastases are present when the primary cancer is first identified or staged. This differs from metachronous metastases, which appear after the original cancer has already been treated. Cancers that can spread to the liver include bowel cancer and pancreatic cancer, among others. Some people have no liver-related symptoms, while others may notice tiredness, reduced appetite, nausea, discomfort under the right ribs, or yellowing of the skin or eyes. These symptoms can have several causes and need clinical assessment.

Doctors usually combine scans with blood tests and a review of tissue from the primary tumour. Imaging helps show whether disease is confined to the liver or present elsewhere, and whether the deposits could be approached directly. A multidisciplinary team may include oncology, surgery, radiology, pathology and specialist nursing professionals.

Ask for a clear explanation of the primary cancer, the areas involved and the purpose of each proposed treatment. Treatment may include systemic therapy such as chemotherapy, surgery to remove selected liver deposits, tumour ablation, radiotherapy, or combinations of these. A liver resection removes part of the liver; tumour ablation destroys a tumour with heat or another energy method. These options depend on anatomy and your wider health, and are not appropriate for everyone.

Keep a record of scan reports, medicines and symptoms, and tell the team about previous treatments, other illnesses and any supplements. Consider asking whether a specialist liver surgeon or a second oncology opinion would add useful information before a major decision.

Contact your oncology team promptly for new or worsening yellow skin or eyes, dark urine, pale stools, increasing abdominal swelling, persistent vomiting, confusion, severe or rapidly worsening pain, fever, or an inability to keep fluids down. Seek emergency care for severe breathing difficulty, collapse, uncontrolled bleeding, or sudden confusion. If you are receiving treatment, follow the urgent-care instructions supplied with that treatment because fever or other symptoms can require rapid review.

Useful questions include: Where did the cancer start? Is the liver the only other organ involved? What do the scans show about the deposits' location and relationship to blood vessels? Is the aim of treatment to remove visible disease, control it, relieve symptoms, or combine these aims? Which tests are still needed? What side effects should be reported immediately, and who should I call outside clinic hours?
