Brain Cancer Treatment with Radiation: Impacts and Coping Strategies
Managing Long-term Side Effects of Brain Radiation Therapy
Brain radiation therapy is a common treatment approach for brain cancer, but it can come with a range of short- and long-term side effects. Up to 90% of people receiving this treatment may experience some level of fatigue, and long-term effects can be more severe and potentially irreversible [1].
Long-term side effects of radiation therapy can include radionecrosis (death of brain tissue), white matter changes, cognitive impairments, neuropathies, and sensory alterations such as hearing loss, taste and smell changes. These effects are often progressive and may be permanent, typically appearing six months or more after treatment [1].
Cognitive deficits, radionecrosis, neuropathies, and other neurological symptoms can develop due to radiation-induced brain injury. Cognitive deficits may involve problems with memory, attention, and executive functions, while radionecrosis can cause localized brain tissue necrosis leading to neurological deficits. Neuropathies may affect cranial nerves, causing sensorineural hearing loss, taste and smell disturbances, swallowing and speech difficulties [1][3].
Fortunately, there are management strategies for these long-term side effects. Symptom-focused treatments, such as corticosteroids to reduce inflammation and edema related to radionecrosis, anticonvulsants for radiation-induced seizures, and rehabilitation therapies like cognitive rehabilitation, speech and swallowing therapy can help manage functional impairments [1][3][5]. Supportive care, including hydration, nutritional support, and treatment of secondary symptoms such as dry mouth or pain, is also crucial.
Regular monitoring and imaging are essential for detecting and assessing progression of radiation-induced brain injury or tumor recurrence requiring further intervention [1][3][5]. It's important to note that early detection and ongoing monitoring can optimize quality of life post-treatment.
In addition to these long-term side effects, short-term side effects such as radiation sickness, nausea and vomiting, hair loss, headaches, skin changes, and fatigue can also occur during treatment [1]. Hair usually grows back within a few months after completing radiation therapy, and dermatologists may be able to prescribe medications to improve the rate at which the hair grows back.
To manage these short-term side effects, people can wear a wig or comfortable scarf, use sunscreen on their scalp and wear a hat when outside, and apply lotions and conditions if the scalp feels itchy. Adequate nutrition and hydration are essential for managing fatigue, and getting plenty of rest, conserving energy, and engaging in light physical activity is important for managing fatigue.
Stereotactic radiotherapy and radiosurgery, which are generally associated with fewer side effects than standard radiation therapy due to their highly targeted nature, can help reduce and manage side effects [1]. However, it's important to discuss potential side effects with a healthcare team, as they can provide personalized information, support, and management strategies to optimize the treatment experience.
In summary, long-term side effects of brain radiation are often irreversible but can be managed through multidisciplinary symptomatic and rehabilitative care tailored to the specific complications present. Early detection and ongoing monitoring are crucial for optimizing quality of life post-treatment.
- Maintaining a balanced nutrition is essential for managing fatigue during brain radiation therapy, which is a common treatment for brain cancer.
- Stereotactic radiotherapy and radiosurgery, known for their targeted nature, may reduce and manage certain side effects related to brain radiation therapy.
- Proton therapy, a type of radiation therapy, can be beneficial in treating brain cancer and may offer less damage to surrounding healthy tissue, potentially decreasing long-term side effects.
- Epilepsy seizures can be a long-term side effect of brain radiation therapy, requiring anticonvulsants for management, alongside rehabilitation therapies and symptom-focused treatments.
- Skin care is important during brain radiation therapy, as it can help alleviate scalp itchiness and improve the rate at which hair grows back after treatment.
