抄録

当院口腔外科にて1981年から2002年の間にレーザーにて舌部分切除術を行った舌扁平上皮癌 (T1, T2N0) 37例について検討した。T分類はT1: 22例, T2: 15例で, 性別は男性23例, 女性14例, 年齢は39歳から79歳 (平均61.8歳) であった。レーザー手術は術中の止血が良好で, 周囲組織への侵襲が少ないため術後の疼痛や浮腫は軽度で, 機能障害は軽微であった。再発は5例 (13.9%), 後発転移は3例 (8.1%) に認められた。再発症例5例中4例がT1症例であった。後発転移症例3例中2例は再発症例で, 頸部非制御のため原病死した。T1, T2N0症例の舌扁平上皮癌に対するレーザー部分切除の累積5年生存率は96.9%であった。舌扁平上皮癌に対するレーザー舌部分切除は表在性癌であれば術後の機能障害を残さず切除可能であり, T1, T2N0症例では筋組織浸潤が7mm未満であれば適応の可能性が示唆された。

A total of 37 patients who had squamous cell carcinoma of the tongue (T1, T2N0) underwent partial glossectomy by laser surgery at the Department of Oral and Maxillofacial Surgery, Kobe University Graduate School of Medicine, between 1981 and 2002. They consisted of 22 of T1 and 15 of T2. Twenty-three of the 37 patients were males and 14 were females. The mean age was 61.8 years, ranging from 39 to 79 years. Laser surgery was able to control hemorrhaging during the operation. It was also able to reduce postoperative pain and edema because of minimal damage to adjacent tissue; this keeps functional disorders to a minimum. Of the 37 patients, local recurrence and regional lymph node metastasis were observed in 5 (13.9%) and 3 (8.1%), respectively. Four of 5 patients in whom local recurrence was observed were T1 cases. Two of 3 patients who had regional lymph node metastasis were also local recurrence cases, and died from regional lymph node metastasis. It is suggested that partial glossectomy by laser surgery is correctly indicated in any superficial tongue cancer leaving no postoperative dysfunction. However, the indication of laser surgery for T1, T2N0 tongue cancer is limited to cases that have invaded the muscle by less than 7mm.
