    ABSTRACT: To retrospectively investigate the therapeutic results of arterial injection therapy by way of the superficial temporal artery for 88 cases of Stage III and IV (M0) tongue cancer and to clarify the factors that affected the therapeutic results. We administered intra-arterial chemoradiotherapy by continuous infusion of carboplatin in 39 patients between January 1993 and July 2002. Systemic concurrent chemotherapy was given to 19 of these patients. We administered intra-arterial chemoradiotherapy with cisplatin with sodium thiosulfate to 49 patients between October 2002 and December 2006. Concurrent systemic chemotherapy was given to 38 of these patients. The 3-year local control rate was 72% (T2-T3, 80%; and T4, 48%), and the 3-year survival rate was 57% (Stage III, 67%; Stage IV, 43%). On univariate analysis, age, T stage, N stage, overall stage, systemic chemotherapy, difference in intra-arterial chemotherapy, and performance status had a significant effect on survival. On multivariate analysis, N stage, systemic chemotherapy, difference in intra-arterial chemotherapy, and artery selected had a significant effect on survival. The therapeutic results of intra-arterial chemoradiotherapy using the superficial temporal artery were not inferior to the results of surgery. In particular, the results of arterial injection therapy using cisplatin with sodium thiosulfate were excellent, and we believe it will be a new therapy for advanced tongue cancer.

    ABSTRACT: To improve the treatment results for locally advanced head and neck cancer, chemoradiation therapy by radiotherapy, systemic chemotherapy with 5-fluorouracil (5FU) and nedaplatin (NDP), and intra-arterial therapy using carboplatin (CBDCA) was performed. Thirty-two patients were entered into the study between July 1997 and August 2002. According to the TNM staging (1997), 14 patients had stage III lesions, and 19 patients had stage IV (M0) lesions. Alternating chemoradiotherapy was performed by the following regimen. Initially, systemic chemotherapy was administered, followed by 4 weeks of radiotherapy (36Gy/20 fractions; wide field irradiation) starting 2 days after chemotherapy, a second course of systemic chemotherapy 2 days after radiotherapy, and a second course of a reduced field radiotherapy (30Gy/15 fractions) 2 days after chemotherapy. Arterial injection therapy was administered in the latter half of radiotherapy after the end of the second course of systemic chemotherapy. For systemic chemotherapy, 5FU at 3500mg/m(2)/120h was intravenously administered for 5 days (Days 1-5), and NDP at 120mg/m(2)/6h was administered on Day 6. An intra-arterial agent using CBDCA was continuously infused by a portable electrical pump for 4 (to 6) weeks. The total dose of CBDCA was AUC 6 as established by Calvert's formula. The 5-year local control rate was 59%. The 5-year overall survival rate was 51%. There were no clinically significant adverse effects. Chemoradiation therapy by radiotherapy, systemic chemotherapy, and intra-arterial chemotherapy for locally advanced head and neck cancer may be useful for improving treatment results.

    ABSTRACT: This study, with a large number of patients, confirms that after administration of 5-fluorouracil (5FU), a higher dose of nedaplatin (NDP) can be safely administered rather than a single therapy of NDP, as demonstrated in a phase I study. The subjects were 52 patients with stage II-IV (M0) head and neck cancer other than nasopharyngeal cancer. Alternating chemoradiotherapy was performed using the following method. Initially, chemotherapy was administered. For chemotherapy, 5FU at 700 mg/m2/24 h was intravenously administered for 5 days (days 1-5), and NDP was administered on day 6. We established three dose groups: level 1, 120 mg/m2; level 2, 140 mg/m2; and level 3, 150 mg/m2 (n = 13 or more per group). The maximum acceptable dose of NDP (150 mg/m2) was confirmed. The 5-year overall survival rates were 77% (95% CI: 66-90%) in all subjects and 75% (95% CI: 61-92%) in the stage III/IV patients. The 5-year progression-free survival rates were 73% (95% CI: 62-87%) in all subjects and 72% (95% CI: 57-89%) in the stage III/IV patients. After administration of 5FU, a higher dose of NDP can be safely administered. This alternating chemoradiotherapy showed potent antitumor effects. The efficacy of chemotherapy with NDP and 5FU should be compared to that of chemotherapy with CDDP and 5FU.

    ABSTRACT: BACKGROUND 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/m2 (total dose, 360 or 400 mg/m2) to 15 mg/m2 (total dose, 405 or 450 mg/m2) and then 20 mg/m2 (total dose, 460 or 500 mg/m2). 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.RESULTSExcluding 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/m2. 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. Cancer 2000;89:2099–5. © 2000 American Cancer Society.
