A unique complication associated with concurrent chemoradiation for the treatment of locally advanced head and neck cancer.

BACKGROUND

Concurrent chemoradiation is becoming an increasingly popular treatment for patients with locally advanced head and neck cancer. The full extent of treatment related complications has not been completely documented in the literature.

METHODS

We present the case of a patient treated with definitive intensity modulated radiation therapy and concurrent carboplatin and fluorouracil for a locally advanced oral cavity and base of tongue cancer.

RESULTS

The patient suffered acute grade 4 dermatitis and mucositis during treatment. One month after completion of treatment, the patient was found to have permanent adherence of the tongue to the buccal mucosa as a result of severe scar tissue formation.

CONCLUSIONS

As more patients undergo chemoradiation for the treatment of locally advanced head and neck cancer, the full extent of treatment related complications are being identified. To our knowledge, this is the first report of chemoradiation for head and neck cancer resulting in adherence of the tongue to the buccal mucosa.
