Understanding Endometrial Cancer: Diagnosis, Treatment & Support

Endometrial carcinoma, also known as uterine cancer, is the most common cancer of the female reproductive system. It originates in the lining of the uterus, called the endometrium. This type of cancer typically affects women after menopause, but it can occur earlier. Endometrial carcinoma is often detected at an early stage due to abnormal vaginal bleeding, which leads women to seek medical attention. Early detection greatly improves the chances of successful treatment.

Risk Factors

Several factors can increase the risk of developing endometrial carcinoma:

  • Age: Most cases occur in women over the age of 50.
  • Hormonal Imbalance: Conditions like polycystic ovarian syndrome (PCOS) or hormone replacement therapy, particularly estrogen therapy without progesterone, can raise the risk.
  • Obesity: Excess body fat can lead to increased estrogen levels, heightening the risk.
  • Diabetes: Women with diabetes may be more susceptible.
  • Family History: A family history of endometrial, ovarian, or colon cancer can increase the risk.
  • Genetic Conditions: Lynch syndrome, a hereditary cancer syndrome, significantly raises the likelihood of endometrial cancer.
  • Tamoxifen: Long-term use of the breast cancer drug tamoxifen may slightly raise the risk.

Symptoms

Common signs and symptoms of endometrial carcinoma include:

  • Abnormal vaginal bleeding, especially after menopause
  • Pelvic pain or discomfort
  • Pain during intercourse
  • Unexplained weight loss
  • Vaginal discharge that may be watery or tinged with blood

If these symptoms persist or worsen, it is essential to consult a healthcare professional for further evaluation.

Diagnosis

Endometrial carcinoma can be diagnosed using a variety of methods, including:

  1. Pelvic Examination: A physical examination of the pelvic area to check for any abnormalities.
  2. Transvaginal Ultrasound: An imaging test that uses sound waves to create images of the uterus and detect changes in the endometrium.
  3. Endometrial Biopsy: A procedure where a small tissue sample is taken from the endometrium to examine for cancerous cells.
  4. Dilation and Curettage (D&C): A more invasive procedure that allows for a larger tissue sample to be collected for analysis.
  5. Imaging Tests: CT scans, MRIs, or PET scans may be used to determine if the cancer has spread.

Treatment Options

  • Surgery: The primary treatment for endometrial carcinoma is surgery, usually involving a hysterectomy (removal of the uterus) along with the removal of the ovaries and fallopian tubes. In some cases, lymph nodes may also be removed to check for cancer spread.
  • Radiation Therapy: Radiation may be used post-surgery or as a primary treatment if surgery is not an option. It helps to destroy remaining cancer cells.
  • Hormone Therapy: For women with advanced endometrial cancer, hormone therapy using progestins may slow the growth of cancer cells.
  • Chemotherapy: Chemotherapy may be recommended for more advanced stages of the disease or if the cancer returns. It is often used in combination with radiation or surgery.

Newer Treatment Options

Recent advancements in the treatment of endometrial carcinoma include:

  • Targeted Therapy: Drugs that target specific molecules in cancer cells to inhibit their growth. For example, inhibitors of the PI3K/AKT/mTOR pathway have shown promise in clinical trials for endometrial cancer.
  • Minimally Invasive Surgery: Laparoscopic and robotic-assisted surgeries allow for less invasive procedures with quicker recovery times, reduced pain, and minimal scarring.

Role of Immunotherapy

Immunotherapy, which boosts the body’s immune system to fight cancer, is an emerging option for treating advanced or recurrent endometrial carcinoma. The most commonly used immunotherapy in endometrial cancer is checkpoint inhibitors like pembrolizumab, which targets the PD-1/PD-L1 pathway to enhance immune response against cancer cells. This approach is particularly effective for tumors with high microsatellite instability (MSI-H) or mismatch repair deficiency (dMMR), making it a personalized treatment option based on tumor genetics.
