Locoregionally recurrent head and neck cancer is a complex clinical scenario that often requires multimodality treatment. These patients have often previously received definitive treatment with a combination of surgery, radiation therapy, and systemic therapy, which can make further management difficult. A second isolated locoregional failure is rare and clinicians are faced with a challenge to optimize disease control while minimizing treatment-related toxicity. In this report, we present the diagnosis, management, and outcomes of a patient with an isolated locoregional recurrence who was previously treated with two courses of radiation. The patient was treated with a second course of reirradiation using interstitial brachytherapy as well as a discussion regarding patient selection and optimal management for recurrent head and neck cancer. Repeat reirradiation using interstitial HDR-brachytherapy with the use of an alloderm spacer was successfully delivered to the patient for an in-field right neck nodal recurrence. He received a total EQD2/BED dose of 127.70/153.24 Gy. At 1-year followup, the patient was without evidence of recurrent disease or new significant side effects. Recurrent head and neck cancer should be managed with a multidisciplinary approach given the complex clinical scenario. Reirradiation is a commonly used salvage measure for recurrent head and neck cancer that requires careful planning and patient selection due to prior treatment-related effects and dose constraints. We reported a case of a second course of reirradiation using interstitial HDR-brachytherapy for locoregionally recurrent head and neck cancer and showed no recurrence of disease or worsening long term side effects at 1 year.
