Brief Summary:
In this study, PA imaging will be used to examine the physiological and physical changes in lymph node involvements of head and neck cancer during radiotherapy with or without chemotherapy. Our objective in this pilot study will be to evaluate if PA parameters change within the lymph node involvements during chemoradiation therapy over time. Our hope is to use this information to correlate the changes in measured PA parameters with radiological response.

Radiotherapy Response Monitoring

Primary Outcome Measures :
  1. Correlation of response to treatment between photoacoustic parameters and final radiological outcome. measures of outcome. [ Time Frame: 3 months ]
    The primary study endpoint will investigate changes of measured PA markers and compare these to radiological assessment of response of lymph node involvement to chemoradiation therapy for head and neck cancer. Changes in PA parameters will be made to a pre-treatment point over the course of treatment.

Secondary Outcome Measures :
  1. Correlation between photoacoustic parameters and five-year overall survival. [ Time Frame: 5 years ]
    The secondary study endpoint will correlate changes of measured PA markers to five-year overall survival (OS) of the same patient cohort. The survival status and of the patient cohort will be tracked after the treatment for five years based on the patient information system and follow up surveys if necessary.
