Overview

Ovarian carcinosarcoma, which is also known as a malignant mixed mullerian tumor (MMMT) of the ovary, is a rare, aggressive cancer of the ovary with two distinct characteristic cancer types i.e carcinoma and sarcoma.

Historical Perspective

[Disease name] was first discovered by [name of scientist], a [nationality + occupation], in [year]/during/following [event].

The association between [important risk factor/cause] and [disease name] was made in/during [year/event].

In [year], [scientist] was the first to discover the association between [risk factor] and the development of [disease name].

In [year], [gene] mutations were first implicated in the pathogenesis of [disease name].

There have been several outbreaks of [disease name], including -----.

In [year], [diagnostic test/therapy] was developed by [scientist] to treat/diagnose [disease name].

Classification

  • There is no established system for the classification of ovarian Sarcoma.[1]
  • Primary ovarian sarcomas occur as pure sarcomas or mixed müllerian tumors (MMTs).
  • Pure sarcomas are comprised of a single malignant mesenchymal element and are further categorized as:
    • Stromal cell sarcomas
    • Fibrosarcomas
    • Leiomyosarcomas
    • Neurofibrosarcomas
    • Rhabdomyosarcomas
    • Chondrosarcomas
    • Angiosarcomas
    • Liposarcomas
  • On the other hand mixed mullerian tumors(MMTs) are defined by the presence of both carcinomatous and sarcomatous elements and are more common than pure sarcomas.
  • Ovarian MMTs can be further classified as homologous or heterologous on the basis of the tissue components present.
  • Homologous tumors contain elements that are native to the ovary whereas heterologous tumors contain elements that normally are not present in the ovary.

The staging of [malignancy name] is based on the [staging system].

OR

There is no established system for the staging of [malignancy name].

Pathophysiology

  • The exact pathogenesis of ovarian sarcoma is not fully understood
  • Clonal loss of the wild-type BRCA2 allele as well as the same somatic mutation of the TP53 gene was evident in histologic components
