The value of high-dose-rate intracavitary brachytherapy (HDRIB) for persistent or recurrent nasopharyngeal carcinoma has been well described; however, the benefit of routine adjuvant fractionated HDRIB following external beam radiation therapy (EBRT) has not been completely determined. The objective of this analysis was to evaluate the outcome of two fractions of adjuvant HDRIB treatment in Tl and T2 nasopharyngeal carcinoma. ⋯ EBRT supplemented by two fractions of adjuvant HDRIB produced a 93.6% local control rate for Tl and T2 nasopharyngeal cancer at 2 years of follow up, with acceptable rates of acute and late toxicity. Brief adjuvant HDRIB appears to permit dose escalation safely, even in patients who receive chemotherapy concurrently with conventional radiation therapy. This strategy needs to be optimized and then tested in a prospective randomized phase III trial to learn if it can improve outcome.

The purpose of this study was to evaluate the role of neck lymph node (ND) in the combined dissection modality therapy for locoregionally advanced head and neck. ⋯ ND improves neck control and is required for patients with clinically residual disease or N3 neck cancer but has no significant impact on the outcome of patients with N2 stage disease who are rendered clinically disease-free with intensive concurrent chemoradiotherapy.
