We performed a medical cost analysis on the use of neoadjuvant chemotherapy (NAC) in multi-modal treatments for advanced tongue and oropharyngeal cancer. Twenty-two patients with stage III and IV squamous cell carcinoma of the tongue and oropharynx were enrolled in this study. Two courses of NAC with CDDP and 5-FU followed by radiotherapy were performed in 13 patients who showed a partial response or a complete response after the first course of NAC. The doses of radiation were 60 Gy for 4 patients (rad. group), and 72 Gy for 9 patients who received hyperfractionated radiotherapy with simultaneous Carboplatin (HF rad. group). Radical surgery was performed in 9 patients who did not respond to NAC (surg. group). The mean duration of hospital stay was 89.3 days for the rad. group, 92.0 days for the HF rad. group, and 113.3 days for the surg. group. The mean medical cost was 238,700 points for the rad. group, 264,846 points for the HF rad. group, and 459,468 points for the surg. group. The mean amounts and percentages of cost for NAC were 39,473 points and 16.1% for the rad. group, 44,802 points and 16.9% for the HF rad. group, and 23,451 points and 5.1% for the surg. group. The mean amounts of cost for NAC including examination costs and nursing costs for chemotherapy were 130,196 points and 54.5% for the rad. group, 150,046 points and 55.7% for the HF rad. group, and 113,839 points and 24.8% for the surg. group. The cost of NAC accounted for half of the total cost of chemo-radiation treatment for functional preservation. The duration of the hospital stay was prolonged by NAC, which accounted for a quarter of the total cost for the surg. group. Survival benefits are considered in the analysis of treatment cost-effectiveness for head and neck cancers. In the future, QOL, which is defined as the utility achieved as a result of multi-modal treatments, should also be analyzed along with survival benefits. Cost-utility analyses should include quality-adjusted life years, based upon the cost identification results of our analysis for NAC, to evaluate the efficacy of NAC in multi-modal treatments for head and neck cancers.
