Background To minimize surgical morbidity, surgery should be performed within 2 to 3 months of completion of radiation therapy with or without chemotherapy. Pathologic demonstration of cancer at this interval is commonly used to justify early surgical salvage of residual primary head and neck cancer. These assumptions regarding head and neck cancer in patients treated with concurrent hyperfractionated radiation therapy and intraarterial supradose cisplatin (HYPERRADPLAT) have never been evaluated. Methods Post‐HYPERRADPLAT clinical and pathologic findings in 42 patients with stage III and IV head and neck cancer were compared with their disease outcomes. All patients underwent an interval analysis of response at 6 to 10 weeks after completion of therapy, 28 of these patients had biopsies of the primary tumor site performed. Results Clinical findings of cancer with pathologic confirmation up to 4 months after therapy can be associated with eventual complete response (CR). Pathologic CR's from deep incisional biopsies can be associated with recurrent disease within 2 months. Six HYPERRADPLAT‐treated patients underwent interval surgical resection of primary disease, and only the four patients with cancer identified in the resection specimen died of recurrent disease. Conclusion In patients treated with HYPERRADPLAT, interval clinical and pathologic assessments may be misleading. Only observation of progressive disease is an accurate predictor of local failure. New evaluation techniques such as metabolic imaging and molecular analysis warrant exploration as tools for interval cancer evaluations. © 2002 Wiley Periodicals, Inc. Head Neck 24: 539–544, 2002
