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
  • 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.
  • 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.

Prognosis

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]%.[6]
  • Depending on the extent of the [tumor/disease progression] at the time of diagnosis, the prognosis may vary. However, the prognosis is generally regarded as poor/good/excellent.
  • 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.
