Metastatic Cancer Therapy
Metastatic cancer treatment basically depends on the original or primary site of the cancer. In some medical conditions, however metastasis of cancer is treated by using combination of treatments. Metastatic cancer therapy involves certain ways of treatment. Metastatic cancer Survival Rate and treatment can be determined by whether the cancer is present only at the originals site or has spread at distant levels. If the cancerous cells have spread into the distant tissues and organs, the patient's likelihood to survive may decrease. However, there are some forms of cancers such as the blood cancer or leukemia that can be treated without spreading at all.
Metastatic cancer therapy includes certain therapies such chemotherapy, radiosurgery, biological therapy, radiation therapy, surgery, hormone therapy or a combination of two or more among these options. The selection of suitable treatment usually depends on the original type of cancer, the location and size of the cancer metastases, general health and age of the patient, and the types of treatments or therapies that have been used earlier. If CUP treatment is used to diagnose the patients, it is likely to perform certain treatments when the primary tumor cannot be found. The standard treatment options that are available currently have rare potential of completely curing the metastatic cancer, although certain tumors such as thyroid cancer and testicular cancer are normally curable.
Metastatic cancer therapy options for different organs:
Surgery - Metastatic cancer surgery can be helpful if the metastases is localized (i.e. present only in one part of the liver)
Chemotherapy performed by an entrenched pump- In this therapy, the tumor is exposed to high concentration drugs. It is used by considering the ability of the liver to metabolize certain drugs.
Chemotherapy combination: Colon cancer that metastases in the liver can be treated with a combination of leucovorin and 5-fluorouracil, irinotecan.
Chemoembolization: This therapy involves using a combination of colloid particles and chemotherapy directly into the tumor of the liver through its hepatic artery. A radiologist performs this procedure without any surgery or bedrest for longer time. This therapy works great for primary tumors, but less for metastases.
Chemotherapy: When the metastases get spread into the less weight bearing bones (weight bearing bones are upper leg, hip and shoulder), chemotherapy can be used to treat the primary tumor.
Radiotherapy: If the tumor gets spread into the weight bearing bones or responds to the chemotherapy appropriately, targeting the cancer cells by using the radiation therapy is the best option. The patient may get complete symptomatic relief quickly. Healing helps to improve the strength of the bones and reduces the possibilities of fracture.
The treatment for metastatic cancer for brain depends of several factors such as the original site of eth tumor, location and number of lesions inside the brain and the extent at which the cancer has spread other than the brain. Surgery -Duration, location and metastases needs to be considered while performing surgery, if the patient has developed only one tumor.
Pamidronate- This medicine can reduce the development of metastases in the bones for some diseases.
Radio therapy- If the patient has developed more metastases, then surgery cannot be the right option to diminish the cancerous tumors. Radiation therapy is used to deal with this condition. Gamma knife: This is a form of radiation therapy that is delivered through the machine to target the involved area by a multiple beams of radiations.
Surgery- In case, if the tumor is isolated surgery can be performed to remove it without causing any damage to the lung function.
Chemotherapy: Used to target the primary type of tumor directly.
Supportive metastatic cancer therapy:
Other types of cancer metastases are also treated with similar metastatic cancer therapy. Some additional therapies may also be used as per the preferences and general health of the patient.
