title: Results of treatment intensification for progressive locoregional disease in head-and-neck cancer patients undergoing postoperative radiotherapy.
abstract: OBJECTIVE
  Patients who develop progressive locoregional disease during radical surgery and postoperative radiotherapy for squamous cell carcinoma of the head and neck represent a management dilemma. We present our experience using treatment intensification for such patients.
  
  
  METHODS
  A prospective record of eligible patients was kept between May 1998 and December 2001. The study included 15 patients, 11 men and 4 women (median age, 60 years); 67% had Stage III-IV disease. The sites of progression were primary in 3, nodes/scar in 10, and both primary and nodes in 2. Relative to the initial plan, treatment intensification was achieved by an increased radiation dose in 7 (using accelerated fractionation in 5), an increased radiation dose and the addition of concomitant chemotherapy in 7, and the addition of concomitant chemotherapy alone in 1 patient.
  
  
  RESULTS
  The median follow-up was 40 months. Eight patients had a complete response to intensified treatment. At the closeout date, 6 patients were alive with no evidence of disease. Eight patients had died with locoregional disease; two also had distant metastases. One patient was lost to follow-up after achieving a complete response. The median failure-free survival for all patients was 6 months, but for those with a complete response, it was 37 months. The median overall survival time was 28 months. The 2-year and 3-year overall survival rate was 50% and 42%, respectively. Acute mucosal and skin toxicity was increased relative to standard postoperative radiotherapy but was not dissimilar to that expected after radical definitive chemoradiotherapy.
  
  
  CONCLUSIONS
  Intensification of treatment in patients who develop progressive locoregional disease is warranted, because it can lead to long-term disease control in a subset of patients with significant but acceptable toxicity.
