Psychiatric Care of the Radiation Oncology Patient.

BACKGROUND: In recent decades, psychiatrists have become increasingly involved in the care of patients with cancer. Psychiatrists are often less familiar with the field of radiation oncology than with other medical specialties.

OBJECTIVE: Therefore, it is beneficial for consulting psychiatrists to be familiar with the basic principles of radiation therapy (RT) and its potential neuropsychiatric sequelae.

METHODS: We performed a PubMed search to identify articles describing neuropsychiatric symptoms resulting from RT, including anxiety, claustrophobia, posttraumatic stress disorder, and neurocognitive impairment. We also searched for other sequelae of RT that may produce psychiatric symptoms, such as radiation necrosis and endocrinopathies. We provide a basic introduction to the delivery of RT.

RESULTS: Psychiatrists may be involved in the treatment of patients before, during, or after RT, and each phase of treatment produces unique considerations. Anxiety about the treatment, especially the need for immobilization with a mask, can be treatment-limiting. Adverse effects from treatment, including cognitive impairment and endocrinopathies, can result in psychiatric symptoms.

CONCLUSIONS: Consulting psychiatrists should be familiar with the basic principles of RT and the neuropsychiatric sequelae that may result from the treatment. Further research is needed to identify strategies to help patients tolerate RT and to identify additional preventive and therapeutic options for RT-induced cognitive impairment.
