Multimodal intensification regimens for advanced, resectable, previously untreated squamous cell cancer of the oral cavity, oropharynx, or hypopharynx: a 12-year experience.

OBJECTIVE

To determine the feasibility of, compliance with, and long-term survival with intensification treatment regimens for patients with advanced, resectable, previously untreated head and neck squamous cell carcinoma.

DESIGN

Prospective phase 2 clinical trial (3 similar, consecutively evolved trials).

SETTING

Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, The Ohio State University.

PATIENTS: One hundred twenty-three patients (median age, 60 years; range, 30-78 years) with previously untreated, resectable, advanced squamous cell carcinomas of the oral cavity, oropharynx, or hypopharynx.

INTERVENTIONS: Perioperative cisplatin chemoradiotherapy, surgical resection with intraoperative radiotherapy, and postoperative paclitaxel and cisplatin chemoradiotherapy.

MAIN OUTCOME MEASURES: The feasibility, compliance, and long-term survival associated with the 3 intensification regimens.

RESULTS

Compliance with all 3 intensification regimens averaged 61% (75/123). Patient-directed noncompliance occurred in 16 patients (13%). The average locoregional (112/123, 91%) and systemic (106/123, 86%) disease control rates were excellent. Overall long-term disease-specific survival was 73%. Median time at risk was 62.5 months (range, 1 day to 100.4 months).

CONCLUSIONS

The intensification regimens result in excellent disease control rates and long-term survival in this particular patient population. Future evolution of these regimens will include some modifications to further decrease toxic effects followed by phase 2 multi-institutional trials to determine whether the single-institutional experience can be duplicated. The results of these studies will determine whether phase 3 trials can be proposed.
