The treatment options for liver cancer are:
Surgery :
Surgery, as a treatment option for liver cancer, is available only for those patients whose tumors are no larger than 5 cm, are confined to the liver, and the cancer has not invaded the adjacent blood vessels, organs or lymph nodes.
There are four types of surgery performed in liver cancer patients:
Partial hepatectomy is a type of surgery where only part of the liver, where the tumor is located, is removed. There are three types of partial hepatectomy: (1) wedge resection, where a triangle-shape slice of tissue is removed, (2) lobe resection, where only the liver lobe is removed, and (3) partial resection, where a large portion of the liver is removed.
Total hepatectomy is a complex surgery where the entire liver is removed. This procedure is followed by a liver transplant because the body cannot live without the liver.
Cryosurgery is a type of surgery that kills cancerous cells by freezing them. This procedure uses the advantages provided by the freezing temperature on the cells. The cells, when exposed to low temperatures, form ice crystals inside that tear apart the cell’s body. The most common substance used as a cooling agent is liquid nitrogen. The nitrogen can be administrated (1) by spraying it on the tissue, (2) through a tube (cryoprobe) inserted into the tissue, or (3) swabbed directly on the tissue. Cryosurgery is a minimally invasive procedure that substantially reduces the patient recovery by minimizing the pain and scars. However, there are several risks involved when this procedure is performed such as the damage of nearby healthy tissue and nerves’ tissue.
Radiofrequency ablation (or RFA) is another minimally invasive, highly successful procedure that removes the liver tumors. Radiofrequency ablation uses radiofrequency current to kill cancerous cells by “cooking“ them. This procedure involves several electrodes, which are placed into the tumor either through the skin, or through small incisions in the abdomen, and send out radiofrequency current that ablates or removes the tumor. This procedure is performed with the help of a CT scan or ultrasound guidance.
Radiation Therapy or Radiotherapy is another treatment approach in the battle against liver cancer. It uses high-energy rays or particles to destroy cancerous cells. Liver cancer patient can receive radiation therapy through several forms.
External radiation therapy uses an external device (linear accelerator) to generate high-energy rays that focuses on the liver tumor.
Internal radiation therapy uses radioactive substances sealed in seeds, wires, needles, or catheters that are placed in the tumor tissue.
Radiolabeled antibodies uses radioactive substances attached to artificially made antibodies to kill cancerous cells. Normally, the body produces different types of antibodies to fight against infections and germs. Each type of antibody fight against a certain cells. The artificial antibodies are designed to kill the liver cancerous cells by radiating them.
The radiation therapy side effects include:
Feeling tired as the treatment continues.
Skin irritation (the skin becomes red, dry, or tender in the area where the body is irradiated).
Loss of appetite.
Vulnerability to infection.
Chemotherapy
Chemotherapy is a systemic treatment (affects cells throughout the entire body) that uses drugs either to stop the abnormal growth and dividing process of the cancerous cells, or to kill them. This type of treatment involves either a single drug, or a combination of several drugs, and it is usually administrated in cycles where a treatment period is followed by a recovery period.
The liver cancer patient can receive chemotherapy differently: (1) as pills, (2) intravenous, as an injection into the vein or through a catheter (a thin, flexible tube) placed in the
