Overview
The prognosis of germ cells of the ovary depends on the type of the tumor and its malignant potentials. Possible complications of benign teratomas are a rupture and ovarian torsion also malignant transformation. Prognosis is generally excellent in the mature teratoma, but in case of simultaneous malignant transformation, the 5-year survival rate of patients is approximately [15-30]%. The 5-year survival rate of the patient even with disseminated dysgerminoma at the time of diagnosis is above 90%. The overall 5-year survival rate for yolk sac tumor, embryonal carcinoma and choriocarcinoma are approximately 80%.
Natural History, Complications, and Prognosis
Natural History
- The symptoms of ovarian germ cell tumors usually develop in the teenage years with abdominal pain or fullness, and palpable pelvic/abdominal mass.[1]
- Dysgerminoma may be misdiagnosed with ectopic pregnancy given the presence of pelvic mass accompanied with high serum concentrations of B-hCG.[2]
- These tumors tend to spread late and do so through lymphatic system primarily.[3]
- These tumors tend to grow rapidly and spread to abdominal/pelvic cavity in early stages.[4]
- They are mostly affects women in their second or third decade of life.[5]
- These tumors tend to metastasize early.[6]
- They spread through the lymphatic system.
- These tumors are highly malignant and tend to spread locally and within the abdominal cavity.[6]
- They spread early in the course of the tumor.
- Non-gestational choriocarcinomas spread through lymphatic system.
- Gestational choriocarcinomas spread through Bloodstream.
Complications
Mature teratoma
Common complications of mature teratoma include:[7]
- Ovarian torsion is the most common complication and affects 5% to 10% of the individuals.
- Rupture in < 4% of the affected individuals.[7]
- Rupture may be associated with leakage of sebaceous contents of the tumor into the peritoneal cavity and leads to granulomatous peritonitis.[9]
- This complication is very rare and happens in less than 1% of the affected individuals.
- Malignant transformation of the tumor may also happen in approximately 2% of affected individuals.[10]
- The tumor undergoes malignant transformation to squamous cell carcinoma in 80% of them and to adenocarcinoma in the rest of the cases.
Dysgerminoma
- Ovarian torsion and acute abdominal pain may occur in < 10% of the cases.[11]
Prognosis
- Only 3% to 5% of ovarian germ cell tumors are malignant which the majority include:[12]
- Dysgerminomas
- Immature teratoma
- Yolk sac tumor

| Immature teratoma | The prognosis of immature teratoma is favorable.[14]
