Survival Rate, Causes, Stages, Symptoms, Treatment & Diagnosis


There are 5 different types of treatment for patients with endometrial cancer.

Different types of treatment are available for patients with endometrial cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

Five types of standard treatment are used:

Surgery

Surgery (removing cancer in an operation) is the most common treatment for endometrial cancer. The following surgical procedures may be used:

  • Total hysterectomy: Surgery to remove the uterus, including the cervix. If the uterus and cervix are taken out through the vagina, the operation is called a vaginal hysterectomy. If the uterus and cervix are taken out through a large incision (cut) in the abdomen, the operation is called a total abdominal hysterectomy. If the uterus and cervix are taken out through a small incision (cut) in the abdomen using a laparoscope, the operation is called a total laparoscopic hysterectomy.
  • Bilateral salpingo-oophorectomy: Surgery to remove both ovaries and both fallopian tubes.
  • Radical hysterectomy: Surgery to remove the uterus, cervix, and part of the vagina. The ovaries, fallopian tubes, or nearby lymph nodes may also be removed.
  • Lymph node dissection: A surgical procedure in which the lymph nodes are removed from the pelvic area and a sample of tissue is checked under a microscope for signs of cancer. This procedure is also called lymphadenectomy.

After the doctor removes all cancer that can be seen at the time of the surgery, some patients may be given radiation therapy or hormone treatment after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that cancer will come back, is called adjuvant therapy.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:

  • External radiation therapy uses a machine outside the body to send radiation toward cancer.
  • Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near cancer.

The way the radiation therapy is given depends on the type and stage of the cancer being treated. External and internal radiation therapy is used to treat endometrial cancer, and may also be used as palliative therapy to relieve symptoms and improve quality of life.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.

Hormone therapy

Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances made by glands in the body and circulated in the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy are used to reduce the production of hormones or block them from working.

Targeted therapy

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibodies, mTOR inhibitors, and signal transduction inhibitors are three types of targeted therapy used to treat endometrial cancer.

  • Monoclonal antibody therapy is a cancer treatment that uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Bevacizumab is used to treat stage III, stage IV, and recurrent endometrial cancer.
  • mTOR inhibitors block a protein called mTOR, which helps control cell division. mTOR inhibitors may keep cancer cells from growing and prevent the growth of new blood vessels that tumors need to grow. Everolimus and ridaforalimus are used to treat stage III, stage IV, and recurrent endometrial cancer.
  • Signal transduction inhibitors block signals that are passed from one molecule to another inside a cell. Blocking these signals may kill cancer cells. Metformin is being studied to treat stage III, stage IV, and recurrent endometrial cancer.
