Uterine Carcinosarcoma

Uterine Carcinosarcoma is a rare and aggressive form of cancer that affects the uterus. This guide provides detailed information about its definition, causes, symptoms, diagnostic methods, treatment options, prevention strategies, and frequently asked questions. Whether you’re seeking knowledge for personal reasons or to support a loved one, this article offers clear and straightforward insights into uterine carcinosarcoma.

Uterine carcinosarcoma, also known as malignant mixed Müllerian tumor (MMMT), is a rare cancer that arises from the uterine lining (endometrium). It contains both carcinoma (cancer that starts in epithelial cells) and sarcoma (cancer that starts in connective tissues) components. This dual nature makes it particularly aggressive and challenging to treat.

Key Points:

  • Rare Cancer: Accounts for less than 5% of all uterine cancers.
  • Aggressive Nature: Tends to grow and spread quickly.
  • Dual Composition: Contains both epithelial and connective tissue cancer cells.

Pathophysiology

Understanding how uterine carcinosarcoma develops and affects the body involves examining the structure of the uterus, its blood and nerve supply.

Structure

The uterus is a hollow, pear-shaped organ located in a woman’s pelvis. It consists of three main layers:

  1. Endometrium: The inner lining where the carcinosarcoma originates.
  2. Myometrium: The thick, muscular middle layer.
  3. Perimetrium: The outermost layer covering the uterus.

Blood Supply

The uterus receives blood through:

  • Uterine Arteries: Branches from the internal iliac arteries supply blood to the uterus.
  • Ovarian Arteries: Provide additional blood flow from the ovaries.

Nerve Supply

Nerves supplying the uterus include:

  • Pelvic Splanchnic Nerves: Involved in involuntary functions.
  • Hypogastric Plexus: Contributes to the sensory and motor functions of the uterus.

Types of Uterine Carcinosarcoma

Uterine carcinosarcoma can be classified based on the types of cells present:

  1. Homologous: Contains sarcomatous elements native to the uterus, such as fibrosarcoma or leiomyosarcoma.
  2. Heterologous: Includes sarcomatous elements not typically found in the uterus, like cartilage or bone tissue.

Causes of Uterine Carcinosarcoma

While the exact cause is unknown, several factors may increase the risk:

  1. Age: More common in women over 60.
  2. Obesity: Excess body weight is a significant risk factor.
