The treatment of liver metastasis
Treatment of liver metastasis of many, but effects were still not satisfied. Have distant metastasis for patients with advanced tumors, in addition to possible treatment by surgical resection, other treatments are no cure, only in the primary tumor resection as possible to adopt the comprehensive treatment approach, the maximum possible to the remission, improve quality of life and prolong survival.
(1) intervention (TACE): Interventional treatment for normal liver function that can not be surgically removed still Element extrahepatic metastases of metastatic liver cancer cases. Because most metastatic liver cancer of the blood supply from the hepatic artery, hepatic artery infusion chemotherapy can improve local tumor concentration of chemotherapeutic drugs, selective destruction of tumor cells stronger than systemic chemotherapy, systemic toxicity is small, the patient can tolerate . Application of intervention embolization therapy may be reduced tumor blood supply, control its growth or ischemic necrosis of the tumor and improve the outcome. Shy oil is most commonly used embolic agent, with chemotherapy drugs injected into the hepatic artery after mixing drugs into tumor blood vessels can improve the local drug concentration in tumor tissue, at the same time to achieve temporary occlusion of tumor blood vessel function, so as to achieve therapeutic purposes . But the actual treatment effect, far better than primary liver cancer, so for this case the treatment element effective alternative therapy should be timely.
(2) systemic chemotherapy: According to the primary tumor site, applications sensitive to chemotherapy drugs, chemotherapy, sensitive to chemotherapy for some tumors can achieve better control rates. Such as breast cancer.
(3) ultrasound guided percutaneous local treatment: such as radiofrequency ablation, microwave therapy, cryotherapy and intratumoral ethanol injection. They are using physical (cold) or chemical action to make cancer cells degeneration, necrosis, so as to achieve therapeutic purposes. It has a little traumatic, patients and well tolerated, side effects is low, the advantages of high efficacy, but the recurrence of the problem is easy to be further addressed.
The treatment of liver metastasis (4) radiotherapy.
(5), immune regulation and biological treatment: generally as an adjunct to cancer therapy. Designed to reduce recurrence and prolong survival, but its efficacy is limited. Preparations are commonly used in clinical vaccine, immune RNA, thymus, skin, interferon and tumor kill factor and so on.
In addition, gene therapy to cancer treatment in recent years a new method, it is through chemical, physical function and viral vectors will be metastatic liver cancer with therapeutic gene into liver cancer cells growth and induce tumor cell itself arrest or apoptosis. I believe in the near future, gene therapy will become one of the primary means of tumor therapy.
