Radiation therapy emerges as a pivotal treatment for melanoma, especially when surgery isn’t feasible. While less common than drug therapies, it offers precise targeting through advanced techniques like VMAT and stereotactic radiotherapy. Personalized plans crafted by expert teams ensure effective management, while understanding side effects and special cases enhances patient care. Explore the evolving landscape of radiation therapy for melanoma.
Understanding Radiation Therapy for Melanoma
Radiation therapy is a critical component in the treatment of melanoma, particularly when surgery is not an option or as an adjunct to surgical procedures. While it is less commonly used compared to drug treatments like immunotherapy, radiation therapy remains a viable option for certain cases of melanoma. The primary type of radiation therapy used is External Beam Radiation Therapy (EBRT), which includes advanced techniques such as Volumetric Arc Therapy (VMAT) and stereotactic radiotherapy. These methods allow for precise targeting of cancer cells, minimizing exposure to healthy tissues (source).
Advanced Techniques in Radiation Therapy
Several advanced techniques are employed in radiation therapy for melanoma, including Stereotactic Body Radiation Therapy (SBRT) and Gamma Knife radiosurgery. These methods offer highly focused, high-dose treatments that can eliminate tumors in fewer sessions compared to conventional radiation therapy. Intensity-Modulated Image-Guided Radiotherapy (IMRT/IGRT) is another advanced technique that uses imaging to tailor radiation beams to the tumor’s shape, allowing for higher doses to the tumor while sparing healthy tissue. This is particularly useful post-surgery when there is a high risk of recurrence (source).
Personalized Treatment Plans
Radiation therapy for melanoma is administered by a specialized team, including radiation oncologists, radiation therapists, medical physicists, and radiation oncology nurses. This multidisciplinary team collaborates to create a personalized treatment plan based on the type and location of melanoma, previous treatments, and the patient’s overall health. Institutions like Memorial Sloan Kettering Cancer Center are at the forefront of providing personalized radiation therapy plans, leveraging cutting-edge treatment options and clinical trials to optimize patient outcomes (source).
Managing Side Effects
Side effects of radiation therapy for melanoma can be categorized into early and late effects. Early side effects, such as fatigue, skin irritation, and hair loss, typically occur during or shortly after treatment and usually resolve within weeks. Late side effects, which may appear months to years later, include skin changes, lymphoedema, and, rarely, secondary cancers. Management of these side effects involves proactive measures such as rest, skin care, and sun protection. For late side effects, ongoing care may include physiotherapy, massage, and consultation with specialists like lymphoedema experts to manage symptoms effectively (source).
Radiation Therapy in Special Cases
Radiation therapy is particularly effective in specific scenarios such as medical inoperability, lentiginous melanoma, mucosal melanoma, and ocular melanoma. Advanced radiation technologies like stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT) offer excellent local control with minimal toxicities, especially for brain, lung, spine, and liver metastases. For ocular melanoma, proton therapy is a specialized form of radiation treatment that utilizes protons to precisely target and destroy cancer cells in the eye (source).
