What Is an Ovarian Germ Cell Tumor?

At a Glance

An ovarian germ cell tumor is a rare, highly curable cancer starting in the egg-producing cells of the ovary. It typically affects teenagers and young women. Treatment usually involves fertility-sparing surgery and chemotherapy, allowing most patients to preserve their ability to have children.

Moving Forward

An ovarian germ cell tumor is a rare type of cancer that begins in the reproductive cells (the cells that produce eggs) of the ovary [1]. If you have been diagnosed with a germ cell tumor rather than an epithelial ovarian cancer, it means your tumor comes from a completely different type of cell, tends to happen at a much younger age, and—most importantly—is highly curable and often allows you to preserve your fertility [2][3][4].

How is a Germ Cell Tumor Different?

Most ovarian cancers discussed in standard resources are epithelial ovarian cancers, which start on the outer surface of the ovary and typically affect older women. In contrast, malignant ovarian germ cell tumors behave very differently:

  • Who they affect: They are most commonly diagnosed in teenagers and young women [2][5].
  • How they grow: Germ cell tumors often grow rapidly, which can cause sudden abdominal pain or a noticeable mass in the pelvis [2].
  • How they respond to treatment: Despite their fast growth, germ cell tumors are exceptionally sensitive to treatment and have a much higher survival and cure rate compared to epithelial ovarian cancer [3][6].

Types of Germ Cell Tumors and Monitoring

There are several subtypes of ovarian germ cell tumors. The specific type you have will help your care team determine the best treatment and follow-up plan [1]. The most common types include:

  • Dysgerminomas: The most common subtype, which often responds very well to treatment [1].
  • Yolk-sac tumors: A subtype that typically produces a specific protein in the blood called alpha-fetoprotein (AFP) [1][7].
  • Immature teratomas: Tumors made of different types of developing tissues. Like the other types, they are highly curable with surgery and systemic therapy [6][8].

To diagnose and track these tumors, doctors frequently rely on tumor markers—special blood tests that look for proteins (such as AFP, LDH, or hCG) produced by the cancer cells [7]. You can expect frequent blood draws during and after treatment, as these markers provide a highly reliable way to monitor how well the treatment is working and watch for any signs of recurrence.

Standard Treatment and Preserving Fertility

The main treatments for germ cell tumors are surgery and chemotherapy. Because these tumors are highly curable and often only affect one ovary, fertility-sparing surgery is the standard of care [4][9].

This surgical approach typically involves removing only the affected ovary and its fallopian tube while safely leaving your uterus and the other healthy ovary in place [10][11]. Extensive surgeries like removing the lymph nodes or the omentum (a layer of fatty tissue covering the abdominal organs) often do not improve survival for early-stage disease and may be skipped [12][13].

After surgery, many patients need chemotherapy to ensure no cancer cells remain. The standard medication used is platinum-based chemotherapy (drugs containing platinum, like cisplatin or carboplatin, that are highly effective at destroying germ cell tumors) [14][15]. While chemotherapy can be intimidating, the crucial piece of information for young patients is that women who receive these specific drugs after fertility-sparing surgery usually maintain normal menstrual function [16].

Even if your cancer is at an advanced stage, fertility-sparing surgery combined with chemotherapy is considered a safe and effective option [9][17]. More importantly, your long-term ability to get pregnant and have healthy pregnancies is comparable to women who have never had the disease [18][11].

Moving Forward

Because this cancer is rare, it is strongly recommended that your treatment be managed by a gynecologic oncologist—a doctor who specializes in treating cancers of the female reproductive system [14][19]. They can tailor a treatment plan that prioritizes completely removing the tumor while protecting your future reproductive goals [20].

Common questions in this guide

How is a germ cell tumor different from other ovarian cancers?
Germ cell tumors start in the egg-producing cells of the ovary and typically affect teenagers and young women. They tend to grow rapidly but are much more sensitive to treatment and have higher cure rates than the more common epithelial ovarian cancers.
Can I still have children after being treated for an ovarian germ cell tumor?
Yes, fertility-sparing surgery is the standard of care for this condition. This surgery removes only the affected ovary, leaving your healthy ovary and uterus intact. Even if chemotherapy is needed, most patients retain normal menstrual function and fertility.
How will my doctor monitor if my germ cell tumor treatment is working?
Doctors use special blood tests to check for tumor markers such as AFP, LDH, or hCG. These are proteins produced by the tumor cells. Checking these levels frequently provides a reliable way to ensure the treatment is working and watch for any recurrence.
What are the different types of ovarian germ cell tumors?
The most common subtypes are dysgerminomas, yolk-sac tumors, and immature teratomas. Knowing your exact subtype is important because it guides your gynecologic oncologist in determining the best chemotherapy and follow-up plan for your specific case.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.What specific subtype of germ cell tumor do I have, and how does that affect my chemotherapy options?
  2. 2.Am I a candidate for fertility-sparing surgery, and is it safe for my specific stage of cancer?
  3. 3.Which specific tumor markers (such as AFP, LDH, or beta-hCG) are you tracking in my blood, and how often will I need to be tested?
  4. 4.If I need platinum-based chemotherapy, what will the timeline look like, and what short-term side effects should I expect?
  5. 5.Given my diagnosis, should I consult with a fertility specialist (reproductive endocrinologist) before starting treatment?
