What is the most common treatment for uterine cancer?

Uterine cancer, also known as endometrial cancer, is one of the most common cancers of the female reproductive system. It originates in the lining of the uterus, called the endometrium. Uterine cancer is often diagnosed at an early stage, as it commonly presents with abnormal vaginal bleeding, which prompts women to seek medical attention. The treatment for uterine cancer depends on the type, stage, and grade of cancer, as well as the patient's overall health. The main treatment options for uterine cancer include surgery, radiation therapy, chemotherapy, and hormone therapy. In many cases, a combination of these treatments is used.

1. Surgery:

Surgery is the most common and primary treatment for uterine cancer, especially in its early stages. The primary goal of surgery is to remove the cancerous tumor and surrounding tissue to prevent the cancer from spreading. The main surgical procedure performed for uterine cancer is called a hysterectomy. A hysterectomy involves the removal of the uterus, and sometimes additional structures may also be removed, depending on the stage and spread of the cancer.

There are different types of hysterectomy procedures, including:

• Total hysterectomy: Involves the removal of the entire uterus, including the cervix. This is the most common type of hysterectomy performed for uterine cancer.

• Radical hysterectomy: This procedure involves the removal of the uterus, cervix, part of the vagina, and surrounding tissues, including lymph nodes and ligaments. A radical hysterectomy is often performed when the cancer has spread beyond the uterus.

• Salpingo-oophorectomy: In some cases, the ovaries and fallopian tubes may also be removed, especially if there is concern that the cancer has spread to these areas or if the woman is at high risk for developing ovarian cancer.

• Lymph node removal: During surgery, the surgeon may also remove lymph nodes near the uterus to determine whether cancer has spread to the lymphatic system. This helps to determine the cancer's stage and may influence subsequent treatment options.

The decision about which type of surgery to perform depends on factors such as the size and location of the tumor, as well as whether the cancer has spread to other organs. Surgical removal of the uterus is the cornerstone of treatment, especially for women who have not yet reached menopause and wish to preserve fertility. However, hysterectomy is not an option for all women, particularly those with advanced or metastatic disease.

2. Radiation Therapy:

Radiation therapy involves the use of high-energy X-rays or other types of radiation to kill cancer cells or shrink tumors. It is commonly used as an adjuvant treatment after surgery to destroy any remaining cancer cells that may not have been removed during the surgical procedure. Radiation therapy is also used when surgery is not an option due to the patient's health or if the cancer is not operable.

Radiation therapy for uterine cancer can be delivered in two primary ways:

• External beam radiation therapy: This method involves directing radiation from outside the body toward the area of the tumor. The patient typically lies on a treatment table while a machine directs the radiation beams to the pelvic area. External beam radiation is typically given over a series of sessions (usually five days a week) for several weeks.

• Brachytherapy (internal radiation therapy): In this technique, a radioactive source is placed inside or near the tumor. For uterine cancer, the radiation source is typically placed in the vagina or cervix, delivering a higher dose of radiation directly to the cancerous tissue while minimizing damage to surrounding healthy tissue. Brachytherapy can be an option for women with early-stage cancer or for those who are unable to tolerate external radiation.

Radiation therapy is effective in treating early-stage uterine cancer or preventing cancer recurrence after surgery. It is often used in combination with surgery for women with higher-risk disease or those with cancer that has spread to the lymph nodes.

3. Chemotherapy:

Chemotherapy involves the use of drugs to kill or control the growth of cancer cells. Chemotherapy is typically used for uterine cancer when the cancer has spread beyond the uterus or when it recurs after surgery. Chemotherapy can be administered orally or through an intravenous (IV) injection, and it works by targeting and killing rapidly dividing cells, which include cancer cells.

Chemotherapy drugs are often used in combination to maximize effectiveness. The most common chemotherapy regimens for uterine cancer include combinations of drugs such as carboplatin and paclitaxel. These drugs are given in cycles, with a period of rest between treatments to allow the body to recover.

Chemotherapy is not typically used for early-stage uterine cancer, as surgery alone is often sufficient. However, it may be recommended for more advanced stages of the disease or for recurrent cancer that has spread to other organs, such as the lymph nodes, lungs, or liver. Chemotherapy may also be used when the cancer is deemed high-risk for recurrence.

4. Hormone Therapy:

Hormone therapy involves the use of medications that block or lower the levels of hormones such as estrogen, which can promote the growth of certain types of uterine cancer cells. Uterine cancer that is estrogen receptor-positive (ER-positive) can sometimes be treated with hormone therapy to slow or stop the growth of cancer cells.

Hormone therapy can be used in various scenarios, including:

• As an adjuvant treatment after surgery: Hormone therapy may be used in combination with other treatments, such as surgery or radiation, for women with higher-risk uterine cancer. It helps to reduce the risk of recurrence by targeting any remaining cancer cells.

• For advanced or recurrent cancer: Hormone therapy may be used when uterine cancer has spread or recurred after initial treatment, especially in cases where chemotherapy is not effective or is not well-tolerated by the patient. Progestins, a form of synthetic progesterone, are often used in hormone therapy for uterine cancer.

• For women who are not candidates for surgery or chemotherapy: Hormone therapy can be used as an alternative treatment for women who are unable to undergo surgery or chemotherapy due to health reasons or other factors.

The effectiveness of hormone therapy depends on the type and grade of uterine cancer. Not all uterine cancers are estrogen receptor-positive, so hormone therapy may not be appropriate for all patients.

5. Targeted Therapy and Immunotherapy:

In some cases, uterine cancer may be treated with targeted therapy or immunotherapy, particularly for advanced or recurrent disease. Targeted therapy uses drugs that specifically target cancer cells based on their molecular characteristics, while immunotherapy boosts the body’s immune system to help fight cancer.

These treatments are still being explored in clinical trials, and their use in uterine cancer is still evolving. Drugs like pembrolizumab (Keytruda), an immune checkpoint inhibitor, have shown promise in some patients with advanced uterine cancers, particularly those with high microsatellite instability (MSI-H) or mismatch repair deficiency.

Conclusion:

The treatment of uterine cancer depends on several factors, including the cancer's stage, grade, and type, as well as the patient's overall health and preferences. Surgery remains the cornerstone of treatment, particularly for early-stage disease, while radiation therapy, chemotherapy, and hormone therapy are commonly used for more advanced or recurrent cases. Emerging therapies like targeted therapy and immunotherapy offer additional options for patients with advanced disease. Given the variety of treatment options and the potential for personalized care, it is crucial for patients with uterine cancer to work closely with their healthcare team to determine the most appropriate treatment plan for their individual situation.
