Germ cell ovarian cancer

Ovarian reproductive cells (germ cells) give rise to ovarian germ cell cancers. Two tiny organs called ovaries are located in the pelvis. The female reproductive system includes ovaries. They create female hormones and eggs.

The majority of benign germ cell malignancies in the ovaries (not cancer). Rarely are the tumors carcinogenic (cancerous). Although they can grow in older women as well, ovarian germ cell tumors typically appear in young women under the age of 20. A tumor often only develops in one ovary.

Chemotherapy or surgery are two options for the treatment of cancerous tumors. The prognosis is based on the cancer’s stage, the size of the tumor, and if it has spread to other areas of your body. The majority of germ cell cancers are curable.

Types of ovarian germ cell tumors

There are several types of germ cell tumors. The most common types of ovarian germ cell tumors are:

• Dysgerminoma: This condition is the most common type of malignant ovarian germ cell tumor.
• Mature teratoma (dermoid cyst or ovarian cyst): This form is the most common type of benign ovarian germ cell tumor.  These noncancerous tumors usually grow in teenage girls and young women.
• Immature ovarian teratoma: This malignant tumor can spread from your ovary to other parts of your body.
• Endodermal sinus tumors: Providers also call this malignant tumor a yolk sac tumor. These tumors grow rapidly and usually affect children and young women.

Stages

After surgery, germ cell tumors are identified. Oophorectomy is the surgical procedure used to remove the ovary. Following a diagnosis of germ cell tumors, medical professionals stage the condition and assign it a classification. The size and location of the tumor are assessed by the professionals. They assess whether the tumor has migrated to nearby tissues or other bodily regions.

Your doctor might request tests like a CT scan to get this information. Your cancer care team can assess the stage of the disease with the aid of these tests.

Stage 1 germ cell tumor typically denotes that the malignancy has not progressed past the ovaries, fallopian tubes, or abdomen. Stages 2 to 4 indicate a more advanced form of the disease with a larger tumor. It has “metastasized” (spread to other body parts).

Germ cell ovarian cancer is a less common form of ovarian cancer that arises from the reproductive cells (germ cells) of the ovary. It occurs in about 2-5% of all ovarian cancers and most commonly occurs in adolescents and young women. Unlike epithelial ovarian cancers, germ cell tumors tend to be found at an earlier stage and are more likely to have a good prognosis. Some common subtypes are dysgerminomas, yolk sac tumors, and immature teratomas. Incidence is greater in women below 30 years of age. With the improvement in treatment, such as surgery and chemotherapy, survival has greatly increased, particularly for early-stage diagnosis.

The exact causes of germ cell ovarian cancer are not fully understood, but certain factors may increase the risk. These include:

1. Genetic Factors: Conditions like gonadal dysgenesis, Turner syndrome, and androgen insensitivity syndrome are associated with an increased risk.

2. Chromosomal Abnormalities: Specific genetic mutations and chromosomal imbalances may trigger abnormal cell growth in the ovaries.

3. Family History: While rare, a family history of ovarian cancer or germ cell tumors may elevate the risk.

4. Developmental Factors: Abnormalities in the formation of reproductive cells during fetal development may also contribute.

Early warning symptoms of ovarian germ cell cancers may be challenging to identify. Malignant tumor symptoms typically don’t show up until the cancer has spread. The following are signs of all ovarian germ cell tumors:

• Pelvic pain or tenderness: Pelvic discomfort, cramping, and ovarian pain are common symptoms of germ cell tumors.
• Swollen belly (abdomen): Young women and girls may have a bloated belly with or without weight gain in other areas of the body.
• Nausea or difficulty eating.
• Changes in bowel habits (constipation).
• Irregular vaginal bleeding.  This is a less common symptom of germ cell tumors. Sometimes, people with these tumors often mistake vaginal bleeding for their regular menstrual cycle. But bleeding that results from an ovarian germ cell tumor is not the same as bleeding during menstruation. Older women may have bleeding after menopause.

Diagnosis of germ cell ovarian tumors is done using the following tests and scans:

• Pelvic exam to check for growths and other abnormalities in your abdomen, pelvis, and vagina.
• Pap smear, a test that looks for abnormal cells in your cervix (the lower part of the uterus).
• Laparoscopy, a procedure that uses small incisions (cuts) and helps your provider look at your organs. Providers may also remove ovaries and take tissue samples for testing (biopsy).
• Laparotomy, a procedure that requires a bigger incision to see a larger part of your abdomen.
• Transvaginal pelvic ultrasound to see images of your reproductive organs.
• CT scan, to see detailed images of your reproductive organs and other soft tissues and to check for tumors.
• Serum tumor marker test, a blood test that checks the levels of certain substances in your body. Higher levels of alpha-fetoprotein (AFP), LDH, or human chorionic gonadotropin (HCG) can be signs of germ cell tumors.
• MRI is an imaging test that produces pictures of organs, soft tissues, and tumors using a high-powered magnet and radio waves.

The best available treatments for germ cell ovarian cancer include:

1. Surgery:
   • Primary Treatment: Often involves removing the affected ovary and fallopian tube (unilateral salpingo-oophorectomy) while preserving fertility when possible.
   • Debulking Surgery: In advanced cases, additional removal of cancerous tissue may be necessary.
2. Chemotherapy:
   • Standard combination regimens like BEP (Bleomycin, Etoposide, and Cisplatin) are commonly used.
   • Chemotherapy is effective, particularly for advanced or recurrent cases.
3. Radiation Therapy:
   • Rarely used, as germ cell tumors respond well to chemotherapy. It may be considered in specific cases like dysgerminomas.
4. Targeted Therapy and Clinical Trials:
   • Participation in trials with novel drugs or targeted therapies is an option for refractory cases.
5. Follow-up and Supportive Care:
   • Regular monitoring and managing side effects with supportive care are crucial for long-term recovery.

Preventing germ cell ovarian cancer is challenging because its exact cause is unknown and there are no specific preventive measures. However, certain steps may help reduce the risk or ensure early detection:

1. Regular Gynecological Exams: Routine pelvic exams and ultrasound screenings can help detect abnormalities early, especially for those with a family history.
2. Genetic Counseling: Individuals with genetic disorders like Turner syndrome or a family history of ovarian cancer may benefit from genetic testing and counseling.
3. Awareness of Symptoms: Recognizing symptoms like abdominal pain, bloating, or irregular menstrual cycles can lead to early diagnosis.
4. Healthy Lifestyle: Maintaining a balanced diet, exercising regularly, and avoiding smoking may contribute to overall cancer risk reduction.
5. Monitoring in High-Risk Individuals: Close medical supervision is advised for individuals with conditions linked to germ cell tumors.

The prognosis for germ cell ovarian cancer is generally favorable, especially when diagnosed early. With modern treatment options, including surgery and chemotherapy, the overall survival rate is high.

• Early-Stage Diagnosis: When detected in early stages (Stage I or II), the 5-year survival rate can exceed 90%.
• Advanced-Stage Diagnosis: Even in advanced stages, effective chemotherapy regimens like BEP (Bleomycin, Etoposide, and Cisplatin) have significantly improved outcomes, with survival rates of 70-80%.
• Dysgerminomas and Immature Teratomas: These subtypes respond well to treatment and have excellent long-term survival.
• Fertility Preservation: Many patients retain fertility with conservative surgery, further enhancing quality of life.

Regular follow-ups are crucial for monitoring recurrence and ensuring continued health.
