A combination therapy of continuous superselective intraarterial carboplatin infusion and radiation therapy for locally advanced head and neck carcinoma. Phase I study.

AbstractBACKGROUND:
To improve the treatment result for locally advanced head and neck carcinoma, the authors used a combination of radiotherapy with superselective continuous intraarterial therapy using carboplatin. The dose limiting toxicity (DLT), maximum tolerated dose (MTD), and treatment effectiveness were tested in Phase I and II protocols. PATIENTS AND METHODS. Thirty-five patients were entered into the study from August 1992 to May 1997. The target arteries were the lingual artery in 18 cases, facial artery in 5 cases, maxillary artery in 11 cases, and external carotid artery initially changing to lingual artery in 1 case. Escalating daily carboplatin doses were tested, starting from 10 mg/m(2) (total dose, 360 or 400 mg/m(2)) to 15 mg/m(2) (total dose, 405 or 450 mg/m(2)) and then 20 mg/m(2) (total dose, 460 or 500 mg/m(2)). Radiotherapy was administered using a 6-megavolt linear accelerator to a total dose of 50-60 grays. Interstitial radiotherapy boost also was used for carcinoma of the tongue.
RESULTS:
Excluding 3 patients who discontinued treatment, the treatment results of 32 patients were complete response in 21 cases, partial response in 10 cases, and no change in 1 case. Neutropenia was the DLT, and the MTD was 500 mg/m(2). The local control rate was 64%.
CONCLUSIONS:
Superselective continuous intraarterial carboplatin and concurrent radiation therapy can be delivered safely with good efficacy for locally advanced carcinomas of the tongue and base of the tongue. Surgical treatment of these diseases usually incurs severe functional loss. This current approach may be a breakthrough in these cancers.
