Reproduction cells (germ cells) in your ovaries give birth to ovarian germ cell cancers. The ovaries and two small pelvic glands are essential for the female reproductive tract. During fertile times, they produce eggs. Someday, the germ cells in your ovaries mature and turn into eggs, or "germ"-inate. When an ovarian germ cell tumor happens, some cells mass together to form a misshapen lump.
Ovarian germ cell tumors often develop in only one ovary but occasionally occur in both.
Most ovarian germ cell tumors are benign (not cancerous) and rarely become malignant (cancerous). Malignant germ cell tumors, which have the potential to spread and harm normal tissue, are an uncommon type of ovarian cancer.
These are the most common types of ovarian germ cell tumors:
Mature teratoma (Dermoid Cyst): The most common type of ovarian germ cell tumors are mature teratomas, or dermoid cysts, which are benign tumors. Most diagnosed individuals are in their teens, twenties, or thirties.
Dysgerminoma: The most common type of cancerous ovarian germ cell tumor is referred to as a dysgerminoma. Most tumors (70 percent of the diagnosis) are not believed to be aggressive (rapid-spreading) and respond well to treatment. Most individuals with diagnoses fall in their 20s or 30s.
Immature teratoma: A fast-growing malignant tumor, an immature teratoma can metastasise—spread from your ovary to other areas of your body. It is more common in people under the age of twenty.
Endodermal sinus tumors or yolk sac tumors are cancers that metastasise rapidly. They are most common in those below the age of twenty. Children who have not yet commenced their periods are affected in up to 40% of the diagnoses.
Mixed germ cell tumors: Malignant tumors referred to as mixed germ cell tumors usually include a mixture of yolk sac and dysgerminoma tumors.
Early treatment is crucial to enhance survival and preserve fertility in germ cell ovarian malignancy. Early treatment, including surgery and chemotherapy, offers a greater chance of eradicating the tumor and halting its spread. Delayed treatment can lead to metastases, issues, and reduced conceptions. Early treatment is most beneficial for remission, organ function, and quality of life.
The early detection of ovarian germ cell cancers may be challenging. Unless they are extensive, benign tumors might not show symptoms, while symptoms of malignant tumors cannot appear until the malignancy has progressed.
Some symptoms to look out out for are:
Causes
Risk Factors
The following are germ cell ovarian cancer risk factors:
Thailand has made great strides in the treatment of germ cell ovarian cancer. Comprehensive support services, such as counseling, nutrition, and rehabilitation, improve patient care, and advanced chemotherapy procedures have increased survival rates. These developments demonstrate Thailand's dedication to offering state-of-the-art, comprehensive cancer care.
There is no method for preventing germ cell cancer. However, regular check-ups can enable your physician to monitor your health and assess your cancer risk.
Surgery: Your doctor might suggest having an oophorectomy to have either one or both of your ovaries or your fallopian tubes removed. If cancer extends beyond your fallopian tubes and ovaries, you would have a total hysterectomy done to have your cervix and uterus removed.
Chemotherapy: When you have chemotherapy, your doctor administers medicine into your veins, typically through an infusion. Chemotherapy medications destroy cancerous cells and prevent them from growing. You'll get chemo treatments for many weeks or even months.

To determine whether a tumor is malignant or not, medical experts apply a process called staging to classify the malignancy. They use imaging methods like positron emission tomography (PET) and CT scans to assess the size and pinpoint the tumour. For the most part, cancer is easier to treat when it is in an earlier stage.
The following are the stages of malignant ovarian germ cell tumors:
Stage 1: The malignancy is confined to your ovaries alone.
Stage 2: Your fallopian tubes or uterus are part of the other pelvic tissues where cancer has spread.
Stage 3: While the cancer has not yet spread beyond your abdomen, it has invaded your lymph nodes and the peritoneum, the lining of your pelvic organs and abdominal cavity.
Stage 4 (metastatic cancer): The cancer has spread to organs and tissues beyond your abdomen, for example, your lungs, or it has grown into your liver or spleen.
No, germ cell ovarian cancer is not very common. Only 2% to 5% of all ovarian cancers are due to it. This type of cancer occurs more in women younger than 30 and predominantly in young women, often in their reproductive years. Although less prevalent than other forms of ovarian cancer, its potential impact on fertility and overall health makes it a cause for concern.
Women under 30 are more likely to get germ cell ovarian cancer, particularly if they have a family history of other ovarian cancers or have inherited syndromes like BRCA1 or BRCA2. Other risk factors are infertility, some ethnic groups, endometriosis, PCOS, and having a past germ cell cancer. It is still a very unusual type of cancer, however, and most women with these risk factors may not develop it.
Germ cell ovarian cancer cannot be entirely prevented at this point. However, a healthy lifestyle, managing risk factors, and regular checkups with the physician can facilitate early detection and a successful outcome from treatment. No specific preventive interventions for germ cell ovarian cancer are available at this time; however, genetic counseling and testing can help estimate risk and guide preventive measures for those with a family history or genetic predisposition.
In Thailand, five-year survival rates for localised instances of germ cell ovarian cancer surpass 90%, indicating that the disease has a generally excellent survival rate, mainly when discovered early. Improved results on par with international norms result from advanced treatments, including chemotherapy and targeted medicines.
Treatments for germ cell ovarian cancer, such as radiation, chemotherapy, and surgery, can alter hormone levels, resulting in irregular menstruation or infertility. However, if there is no ovarian damage, some women might continue to have regular periods.
Genetic testing might be beneficial to patients with germ-cell ovarian cancer, especially if the patient was diagnosed at a young age or if there is a family history of the illness. Testing can identify inherited mutations in the BRCA1 or BRCA2 genes, which are more commonly associated with other types of ovarian cancer but are still applicable.
Genetic testing can also help determine treatment possibilities and assess family members' risk. However, routine genetic testing for germ cell ovarian cancer is not typically performed in the absence of specific risk factors or signs.
Treatment for germ cell ovarian cancer lasts different lengths of time, from a few months for early instances to a year or longer for advanced stages. For long-term monitoring, ongoing treatments and follow-ups might be required.
In Thailand, you can locate a skilled gynecologic oncologist by looking into hospitals with specialist cancer centres accredited by JCI. To assist you in selecting the best expert, several hospitals offer teleconsultations, international patient coordinators, and online directories of doctors. Finding skilled oncologists with foreign training might also be aided by patient recommendations and medical tourism organisations.
Yes, top hospitals and specialist doctors in Thailand can provide you with a second opinion regarding the treatment of germ-cell ovarian cancer. Numerous hospitals offer telemedicine services, multidisciplinary tumour boards, and in-person consultations to assess your situation and offer professional advice on the best course of therapy.
