Tumors often have hypoxic (low oxygen) regions that are an
obstacle to radiation therapy treatment. Oxygen is required for radiation
therapy to eradicate cancer cells to ensure the damage to DNA caused by
radiation is permanent. Hypoxic cells are radioresistant because in the absence
of oxygen, the cells can repair themselves. There are multiple methods used to
overcome this problem, including dose painting where low oxygen regions are
identified with positron emission tomography and targeted.
This quiz is the companion to the short report, "Oxygen as a Radiosensitizer and its Use to Overcome Hypoxia During External-Beam Radiotherapy", which appears in the Fall 2022 Radiation Therapist journal.
This activity may be available in multiple formats or from different sponsors. ARRT regulations state that an individual may not repeat a self-learning activity for credit if it was reported in the same biennium.
Free access is included with membership. All titles for which you have not previously earned CE credit appear in your CE library.
