Ovarian germ cell tumor natural history
Introduction
Overview
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, 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
| Prognosis of ovarian germ cell tumors | |

| Mature teratoma | 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]%.[13] |
| Immature teratoma | The prognosis of immature teratoma is favorable.[14]
