What is the role of radiation therapy in mesothelioma?

Radiation therapy plays a significant role in the management of mesothelioma, a type of cancer that affects the lining of the lungs, abdomen, heart, or other organs. While surgery and chemotherapy are also commonly used in treating mesothelioma, radiation therapy can be an essential part of a patient’s treatment plan. Here’s how radiation therapy functions in the context of mesothelioma:

  1. Localized Treatment: Radiation therapy is employed to target and destroy cancer cells in specific areas of the body. It’s often used when the cancer is localized and hasn’t spread extensively. For mesothelioma, it can be utilized after surgery (adjuvant therapy) to eliminate any remaining cancer cells or as part of a multimodal approach along with chemotherapy.
  2. Palliative Care: In cases where the cancer is more advanced and surgery isn’t an option, radiation therapy serves as a palliative treatment to alleviate symptoms and improve quality of life. It can help in reducing pain, controlling bleeding, and managing other symptoms associated with mesothelioma.
  3. Types of Radiation Therapy: There are two primary types of radiation therapy used in mesothelioma treatment:
    • External Beam Radiation Therapy (EBRT): This involves directing high-energy X-rays or other forms of radiation from outside the body onto the cancerous tissues. It’s a common form of radiation therapy for mesothelioma.
    • Brachytherapy: In some cases, doctors may use brachytherapy, where radioactive sources are placed directly into or near the cancerous area. This allows for a more targeted and localized delivery of radiation.
  4. Potential Side Effects: Like any cancer treatment, radiation therapy can cause side effects, which may include fatigue, skin changes at the radiation site, nausea, and other localized symptoms depending on the area being treated. However, advancements in radiation therapy techniques have helped to minimize side effects while maximizing the treatment’s effectiveness.
  5. Combination Therapy: Often, radiation therapy is used in combination with other treatments such as surgery and chemotherapy. This multimodal approach aims to improve outcomes and enhance the effectiveness of the overall treatment plan.

It’s important to note that the decision to use radiation therapy in mesothelioma treatment depends on various factors including the stage of the cancer, the patient’s overall health, and the specifics of the individual case. Treatment plans are usually personalized and tailored to meet the needs of each patient.

Consultation with a multidisciplinary team of healthcare professionals, including oncologists and radiation oncologists, helps in determining the most suitable treatment approach for mesothelioma patients.
