Observations on Control of N2 and N3 Neck Disease in Squamous Cell Carcinoma of the Head and Neck by Intra-arterial Chemoradiation

Patients with head and neck squamous cell cancer with N2 and N3 neck disease have a poor prognosis and are at risk to fail regionally despite combined surgery and radiation. Twenty‐two patients with N2 and N3 neck disease (and T3‐4 primaries) were treated with intra‐arterial, high‐dose cisplatin (CDDP), 150 mg/m2 per week for 4 weeks, and concurrent radiation. All patients were followed for at least 2 years or until death from any cause. Twenty patients had a complete response at the primary site. Two of the 20 with a complete response later had a neck recurrence and died. Five patients with palpable nodes after treatment underwent fine‐needle aspiration (FNA), one of which was positive and two suggestive of cancer. Six neck dissections were performed in this group, only two of which had positive nodes. This chemoradiation protocol may offer reasonable control of N2 and N3 neck disease in advanced head and neck squamous cell cancer. Neck dissection appeared to be necessary in only those patients with nodes 8 weeks after treatment in whom FNA was positive or suggestive of cancer. Because of the relatively small size of this series, additional accrual and monitoring of such patients is planned.
