Ovarian Cancer Treatment Options at Penn

---

Different treatments are available for those with epithelial ovarian cancer and ovarian germ cell cancer. Some treatments are called standard. This means they are the currently used treatments. Some treatments are being tested in clincal trials. A treatment clinical trial is a study meant to help improve current treatments or obtain information on new treatments.

When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. You may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment, while others are available during or after treatment.

Treatment options vary depending on your situation including the stage of the cancer and other factors that may be present.

Options for Ovarian Epithelial Cancer

There are different types of treatment for patients with ovarian epithelial cancer.

Three types of standard treatment are used:

Surgery

Most patients have surgery to remove as much of the tumor as possible. Different types of surgery may include:

• Total hysterectomy: is 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.
• Unilateral salpingo-oophorectomy: is surgery to remove one ovary and one fallopian tube.
• Bilateral salpingo-oophorectomy: is surgery to remove both ovaries and both fallopian tubes.
• Omentectomy: surgery to remove the omentum (a piece of the tissue lining the abdominal wall).
• Lymph node biopsy: The removal of all or part of a lymph node. A pathologist views the tissue under a microscope to look for cancer cells.

Radiation therapy

• External radiation (or external beam radiation) comes from a machine outside the body. The machine directs high-energy rays at the cancer and some normal surrounding tissue. It is the most often used radiation treatment. The machine used to deliver the high-energy rays is called a linear accelerator.

• Three-dimensional (3-D) conformal radiation treatment is a type of external beam radiation. It uses computers to allow doctors to more precisely target a tumor with radiation beams (using width, height, and depth).

• Intensity-modulated radiation treatment (IMRT). IMRT is a type of 3-D conformal radiation treatment that uses radiation beams (usually x-rays) of
  various intensities to give different doses of radiation, at the same time, to small areas of tissue. This allows the delivery of higher doses of radiation to the tumor and lower doses to nearby healthy tissue.

• Internal radiation treatment, or brachytherapy, is given by placing an implant into or near the tumor. The implant is a small container that holds the
  radioactive source or material. Internal radiation treatment allows your doctor to give a higher total dose of radiation to a smaller area and in a shorter time than with external radiation treatment.

• Photodynamic therapy (PDT) combines a drug called a photosensitizer or photosensitizing agent with a specific type of light to kill cancer cells.
  Photosensitizers are drugs that when exposed to a specific wavelength of light, produce a form of oxygen that kills nearby cells. PDT can also work by shrinking or destroy tumors by damaging blood vessels in the tumor. This
  prevents the cancer from receiving nutrients. Also, PDT may activate the
  immune system to attack the tumor cells.

• Stereotactic radiosurgery is a a type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiation to a tumor. It is used to treat brain tumors and other brain disorders that cannot be treated by regular surgery. It is also being studied in the treatment of other types of cancer. Also called radiation surgery, radiosurgery, and stereotaxic radiosurgery.

• Proton Therapy is the most precise form of radiation treatment for cancer possible, while minimizing damage to healthy tissue and surrounding organs.

The way the radiation therapy is given depends on the type and stage of the cancer being treated.

Some women receive a treatment called intraperitoneal radiation therapy, in which radioactive liquid is put directly in the abdomen through a catheter.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them 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 an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy).

A type of regional chemotherapy used to treat ovarian cancer is intraperitoneal (IP) chemotherapy. In IP chemotherapy, the anticancer drugs are carried directly into the peritoneal cavity (the space that contains the abdominal organs) through a thin tube.

Treatment with more than one anticancer drug is called combination chemotherapy.

The way the chemotherapy is given depends on the type and stage of the cancer being treated.

Treatments that are being studied in clinical trials:

Biologic therapy

Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.

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.

Options for Ovarian Germ Cell Tumors

There are different types of treatment for patients with ovarian germ cell tumors.

Three types of standard treatment are used:

Surgery

Surgery is the most common treatment of ovarian germ cell tumor. A doctor may take out the cancer using one of the following types of surgery.

• Unilateral salpingo-oophorectomy: is surgery to remove one ovary and one fallopian tube.
• Total hysterectomy: is 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: is surgery to remove both ovaries and both fallopian tubes.
• Tumor debulking: is surgery in which as much of the tumor as possible is removed. Some tumors may not be able to be completely removed.

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.

Adjuvant Therapy: Even if the doctor removes all the cancer that can be seen at the time of the operation, some patients may be offered chemotherapy or radiation after surgery to kill any cancer cells that are left. Treatment given after the surgery to increase the chances of a cure is called adjuvant therapy.
Following radiation or chemotherapy, an operation called a second-look laparotomyis sometimes done. This is similar to the laparotomy that is done to determine the stage of the cancer. During the second-look operation, the doctor will take samples of lymph nodes and other tissues in the abdomen to see if any cancer is left.

New types of treatment are being tested in clinical trials include:

High-dose chemotherapy with bone marrow transplant

High-dose chemotherapy with bone marrow transplant is a method of giving very high doses of chemotherapy and replacing blood-forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells.

New treatment options

Combination chemotherapy (the use of more than one chemotherapy drug to fight cancer) is being tested in clinical trials.
