Dysgerminoma

Dysgerminoma is a type of germ cell tumor that is usually found in the ovary. It is the most common malignant germ cell tumor in females. Dysgerminomas are similar to the seminoma, a type of testicular cancer, as both produce LDH (lactate dehydrogenase).

Symptoms

The most common symptom of dysgerminoma is a painless enlargement of the ovary. Other symptoms may include abdominal pain, bloating, or constipation. In some cases, dysgerminoma can cause precocious puberty in children due to the production of human chorionic gonadotropin (hCG).

Diagnosis

Ultrasound is often the first test done when a dysgerminoma is suspected. Other tests may include a CT scan or MRI to determine the size and location of the tumor. Blood tests may be done to check the levels of certain substances, such as LDH, hCG, and alpha-fetoprotein (AFP), which can be elevated in people with dysgerminoma.

Treatment

Treatment for dysgerminoma usually involves surgery to remove the tumor. This may be followed by chemotherapy or radiation therapy to kill any remaining cancer cells. The choice of treatment depends on the stage of the cancer and the patient's overall health.

Prognosis

The prognosis for dysgerminoma is generally good, especially if the cancer is detected early and treated promptly. The 5-year survival rate for stage I dysgerminoma is over 90%.
