Summary

The primary purpose of this research is to investigate anti-tumor immune responses in patients undergoing chemotherapy and radiation for Head and Neck Cancers. Hypothesis: Treatment of HPV-associated OPSCC with concurrent chemoradiation results in changes in the tumor microenvironment. We hypothesize that these changes during daily fractionated chemoradiotherapy can lead to detectable changes in HPV-specific tumor immune responses. Hypothesis: HPV-specific cellular immune responses can still be detected during radiotherapy in the presence or absence of lymphopenia. * This study will determine whether specific anti-tumor immune responses (Specific Antibodies and Specific T-cells) can be detected in patients undergoing chemoradiation treatment for Head and Neck Cancers. * This study will evaluate the presence or absence of HPV (human papillomavirus) specific immune responses before, during, and after treatment for Head and Neck Cancers. * This study will also evaluate whether decreased white blood cell counts may affect development of immune responses in Head and Neck cancer patients undergoing treatment. Any head and neck cancer patient undergoing concurrent chemoradiotherapy is eligible if: you are older than 18 years of age, capable of providing informed consent, have a life expectancy of greater than 4 months, and have a good performance status. You are eligible irregardless of your HPV positive or negative status. People with HPV positive (human papillomavirus associated) head and neck cancer may join. People with HPV negative head and neck cancer may also join.

Detailed description

As this is a pilot study seeking to describe the potential impact of chemoradiotherapy on the natural history of any immunologic response in HPV-associated OPSCC, the timing of the venipunctures reflect the goal to sample throughout the course of CTRT (chemoradiation therapy)and will permit some variability based on the number of radiation fractions delivered. It also reflects considerations of time points that lend themselves to both the venipuncture and tumour biopsy based on the toxicity and response profile of the chemoradiation in the HPV-associated OPSCC patient. As such, 10 subjects with HPV-associated OPSCC and 10 subjects with non-HPV associated HNSCC seen by the respective disciplines of otolaryngology-head and neck surgery, radiation oncology, or medical oncology as clinically indicated will be enrolled on this clinical protocol. Importantly, clinical therapeutic recommendations, radiation treatment plans, and therapeutic drugs will not be altered by enrollment in this protocol. Tumors which are directly visible through in office laryngopharyngoscopy and easily accessible (i.e. oropharyngeal tonsil) will be directly biopsied (non-percutaneously) and analyzed as detailed below.
