MCQ Pathology Answer 13

The Correct Answer is E

High-dose radiation therapy is the primary treatment of nasopharyngeal cancer, both for the primary tumor site and the neck.

Surgery, when feasible, is usually reserved for nodes that fail to regress after radiation or for nodes that reappear following clinical complete response. Radiation therapy dose and field margins are individually tailored to the location and size of the primary tumor and lymph nodes.

Although most tumors are treated with external-beam irradiation exclusively, in some tumors radiation therapy may be boosted with radioactive intracavitary or interstitial implants when clinical expertise is available and the anatomy is suitable.

A review of published clinical results of radical radiation therapy for head and neck cancer suggests a significant loss of local control when the administration of radiation therapy was prolonged; therefore, lengthening of standard treatment schedules should be avoided whenever possible.
