Abstract

Objectives: To determine the tumor interstitial fluid pressure(TIFP) in patients with head and neck cancerand predict radiotherapy outcome.Materials and Methods: In 12 biopsy proven primary head and neck cancer patients with accessible by direct inspection and palpation, and of sufficient thickness(>1cm) to permit accurate needle placement, we measured TIFP at cervical lymph node before and during radiotherapy using a modified wick-in-needle technique. Tumor size was measured clinically and radiologically. Results: The mean preradiotherapy TIFP was 23.4mmHg. Preradiotherapy TIFP had significant relationship with tumor size(p=0.0009). Preradiotherapy TIFP was not different between complete response group and partial or less response group(p=0.114). Radiotherapy outcome was not different between group with above and group with below average TIFP(p=0.09). Conclusion: The mean TIFP was elevated with 23.4mmHg before radiation therapy. Preradiotherapy TIFP had significant relationship with tumor size. It is not definitive that TIFP could be prognostic indicator of radiation response.
