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. If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
OR
Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
OR
Prognosis is generally excellent/good/poor, and the 1/5/10-year mortality/survival rate of patients with [disease name] is approximately [#]%.
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]
- The symptoms of (disease name) typically develop ___ years after exposure to ___.
- If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
Complications
Mature teratoma
Common complications of mature teratoma include:[2]
- Ovarian torsion is the most common complication and affects 5% to 10% of the individuals.
- It happens at a greater extent in:[3]
- Younger age (10-19 years)
- Larger tumors
- It happens at a greater extent in:[3]
- Rupture in < 4% of the affected individuals.[2]
- Rupture may be associated with leakage of sebaceous contents of the tumor into the peritoneal cavity and leads to granulomatous peritonitis.[4]
- This complication is very rere and happens in less than 1% of the affected individuals.
- Rupture may be associated with leakage of sebaceous contents of the tumor into the peritoneal cavity and leads to granulomatous peritonitis.[4]
- This tumor may be bilateral in 8% to 15% of cases.
- Malignant transformation of the tumor may also happen in approximately 2% of affected individuals.[5]
- The tumor undergoes malignant transformation to squamous cell carcinma 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.[6]
Prognosis
- Only 3% to 5% of ovarian germ cell tumors are malignant which the majority include:[7]
- Dysgerminomas
- Immature teratomas
- Yolk sac tumors
- Pure form
- Part of a mixed germ cell tumor
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]%.[8]
- The presence of [characteristic of disease] is associated with a particularly [good/poor] prognosis among patients with [disease/malignancy].
- [Subtype of disease/malignancy] is associated with the most favorable prognosis.
- The prognosis varies with the [characteristic] of tumor; [subtype of disease/malignancy] have the most favorable prognosis.
Dysgerminoma
- Depending on the stage of the tumor at the time of diagnosis, the prognosis may vary. However, the prognosis is generally regarded as good.[9]
- The 5-year survival rate of the patient even with disseminated disease at the time of diagnosis is above 90%.
- Reoccurence of the tumor may occur within 2-years of diagnosis and is curable.
- For stage A1 the reocurrence rate is approximately 20% in 2-years.
