Radiation therapy (RT) interruptions have been shown to compromise local control in the definitive treatment of head and neck cancer (HNC). Superstorm Sandy (SS) brought the destruction of treatment units, patient immobilization devices, as well as the loss of electrical power at our hospital, resulting in treatment interruptions. Here, we review the clinical outcomes of patients nearly one year after the start of treatment. All patients undergoing RT for HNC during SS were included. Duration of treatment interruptions were recorded for all patients. Alterations in fraction number and schedule to address breaks in an attempt to mitigate their effect on tumor control were calculated by each treating physician and recorded for all patients. Clinical status at most recent follow up was recorded. Twelve patients were actively undergoing RT for HNC during SS. Seven patients had their immobilization device destroyed and required re-simulation and re-planning. Of these, six patients were treated through weekends without breaks and 3 patients had fractions added; the median prolongation of RT course was 12 days. Five patients' immobilization devices were not destroyed, 4 of them continued RT through weekends without breaks, one received an extra fraction of RT; the median prolongation of RT course was 5 days. At a median follow up of 9.6 months, 9 patients were alive with no evidence of disease, 1 developed metastatic disease, 1 was lost to follow up and 1 patient committed suicide. Ten of eleven patients (91%) achieved a clinical complete response (cCR), 7 had cCR at the time of first imaging following RT, one patient had cCR by physical exam but committed suicide prior to imaging, and two patients had persistent FDG uptake on follow up PET-CT, which was biopsied and was negative for persistent or recurrent cancer. Nearly one year following SS, HNC patients who underwent RT have not developed a high number of early local recurrences and had an excellent cCR rate. Alterations in RT scheduling and additional fractions may have compensated for prolongation of RT course. Longer follow up is required to determine if this population will suffer higher rates of recurrence compared to historical standards.
