Choriocarcinoma of the Ovary: A Rare and Aggressive Form of Cancer

Choriocarcinoma of the ovary is a rare and aggressive form of cancer that arises from the ovaries. It is a type of germ cell tumor, which means it originates from the cells that produce eggs in the ovaries.

Types of Choriocarcinoma

There are two types of choriocarcinoma: gestational and nongestational. Gestational choriocarcinoma arises from an ovarian pregnancy or is a metastasis from a uterine or tubal choriocarcinoma, while the nongestational type is a rare germ cell tumor with trophoblastic differentiation.

Incidence and Age

Choriocarcinoma of the ovary is extremely rare, with an estimated incidence of less than 0.6% of all ovarian tumors. It typically affects women under 40 years old, although it can occur at any age.

Symptoms and Diagnosis

The symptoms of choriocarcinoma of the ovary may include precocious pseudopuberty and vaginal bleeding in children and young adults. Serum human chorionic gonadotropin (hCG) is often elevated. The diagnosis is typically made through imaging studies, such as ultrasound, and biopsy.

Treatment and Prognosis

The treatment for choriocarcinoma of the ovary usually involves surgery, chemotherapy, or a combination of both. The prognosis is generally good, with an 80% 5-year survival rate.

Choriocarcinoma of the ovary is a rare and aggressive type of cancer that can be challenging to diagnose. However, several diagnostic tests can help identify this condition.

Imaging Tests

• Pelvic ultrasound: This test uses high-frequency sound waves to create images of the ovaries and surrounding tissues. It can help detect any abnormalities or masses in the ovaries (1).
• Computed Tomography (CT) scan: A CT scan uses X-rays and computer technology to create detailed images of the internal organs, including the ovaries. It can help identify any tumors or cysts in the ovaries (2).
• Magnetic Resonance Imaging (MRI): An MRI uses magnetic fields and radio waves to create detailed images of the internal organs, including the ovaries. It can provide more detailed information about the size, shape, and location of any tumors or cysts (2).

Blood Tests

• Human chorionic gonadotropin (hCG) test: This blood test measures the level of hCG in the blood, which is a hormone produced by the placenta during pregnancy. Elevated levels of hCG can indicate choriocarcinoma of the ovary (3).
• CA-125 blood test: This blood test measures the level of CA-125, a protein that can be elevated in people with ovarian cancer, including choriocarcinoma (4).

Other Tests

• Pelvic exam: A pelvic exam involves a physical examination of the ovaries and surrounding tissues to check for any abnormalities or masses (7).
• Complete blood count (CBC): This test measures the levels of different cells in the blood, including red and white blood cells. It can help identify any changes in the blood that may indicate cancer (1).

It's worth noting that the pre-operative diagnosis of pure ovarian choriocarcinomas is very difficult, especially for patients in the reproductive age due to non-specific symptoms (6). Therefore, a combination of imaging tests and blood tests may be necessary to confirm the diagnosis.

Treatment Options for Choriocarcinoma of Ovary

Choriocarcinoma, a rare and aggressive form of ovarian cancer, requires prompt and effective treatment to manage the disease. The main treatment options for choriocarcinoma include:

• Chemotherapy: Chemotherapy is the primary treatment for choriocarcinoma, using drugs such as Bleomycin, Etoposide, and Cisplatin (BEP) [9] or other regimens like EMA-CE [5]. This treatment approach has shown excellent activity in treating malignant germ cell tumors [9].
• Surgery: Surgery may be necessary to remove the affected ovary or uterus (hysterectomy), especially if the cancer is localized [2, 3].
• Radiation Therapy: Radiation therapy may also be used as part of the treatment plan, particularly for advanced cases [7].

Importance of Early Treatment

It's essential to initiate treatment promptly, as early intervention can significantly improve outcomes. Evaluating treatment options with a medical team and starting the process as soon as possible is crucial for better results [2].

Chemotherapy Protocols

The most recent case reports describe treatment with BEP, which has shown excellent activity in other malignant germ cell tumors [9]. Other chemotherapy regimens like EMA-CE have also been effective in treating choriocarcinoma [5].

[1] The main treatment for choriocarcinoma is chemotherapy. Chemotherapy is a drug that kills cancer cells. Some people may also need surgery to remove their uterus (hysterectomy), radiation or a combination of treatments. After treatment, your healthcare provider will schedule follow-up exams to make sure the cancer doesn’t return. [2] Choriocarcinoma treatment usually includes chemotherapy, surgery, or radiation therapy. For better outcomes, it is important to evaluate your options with your medical team and start the treatment process as soon as possible. Treatment options will depend on your overall health and how far the cancer has advanced. [3] In most choriocarcinoma cases, the cancer is treated with chemotherapy, which is a medical treatment to destroy cancer cells using drugs. It’s usually given intravenously and is a very successful treatment option for choriocarcinomas. Sometimes, radiation and/or a hysterectomy may be used. Treatment decisions are made by patients and their ... [4] BEP chemotherapy is the first treatment choice for ovarian germ cell tumors. Since primary ovarian choriocarcinoma is considered to be a type of ovarian germ cell tumor, BEP chemotherapy would likely be an effective treatment option. [5] A drug regimen called EMA-CE has been used to treat choriocarcinoma with success. [9] The use of Bleomycin, Etoposide, and Cisplatin (BEP) as a chemotherapy regimen for treating malignant germ cell tumors, including choriocarcinoma, is discussed in this reference.
