Which of the following is NOT typically considered an acute side effect of thoracic radiation therapy?

A treatment planner uses beams that enter the patient from angles outside a single geometric plane, allowing the dose to wrap around a tumor while avoiding the spinal cord. This beam arrangement is known as:

Which primary tumor region requires coverage of the sphenoid sinus, cavernous sinus, and skull base?

Radiation therapists treating lung cancer patients should monitor for symptoms of brain metastases. Which of the following would be LEAST likely to indicate brain metastasis?

A patient is treated using 40 Gy delivered in 15 fractions over three weeks. Compared with conventional fractionation, this schedule uses a higher dose per fraction and fewer total fractions known as

A head and neck cancer patient is treated with a regimen in which two smaller fractions per day are delivered with a slightly increased total dose. This fractionation strategy is called:

According to standard NCCN and QUANTEC-based guidelines using standard fractionation, the V20 for total lung should typically be kept to less than about:

When reviewing a DVH for parallel organ response, the planner concluded that the small hot spots are more clinically significant than a similar hot spot in a serial response organ. Is the planner correct or not?

Coplanar arrangements generally improve conformity and normal tissue sparing compared with non-coplanar beams.

The Quantitative Analyses of Normal Tissue Effects in the Clinic (QUANTEC) publications expanded upon the tolerance data originally published by Emami et al. by incorporating modern three-dimensional dose–volume information and clinical outcomes data.
