外耳道癌是一种具有高度复发倾向的侵袭性疾病,主张在早期施行根治性手术治疗。自1968年以来我们曾收治10例外耳道原发肿瘤,其中5例曾在早期接受过局部小范围切除,术后复发并向周围扩展,而行补充根治手术,术后除1例尚在观察外,其余4例均在3年内再次复发死亡;另5例首诊便施行根治性切除及术后放射治疗,3例已存活10年以上,2例已分别存活4年及5年无复发。以上资料表明,对外耳道癌只有早期诊断与彻底治疗始能获得良好疗效。局部切除容易复发,不宜采用。
External auditory canal cancer is a highly recurrent aggressive disease that advocates radical surgery in the early stages. Since 1968, we have treated 10 cases of external auditory canal primary tumors, of which 5 cases had undergone partial small resection in the early postoperative recurrence and to the surrounding expansion, and the line of radical surgery, in addition to one case was still under observation , And the remaining 4 patients all died of recurrence within 3 years. The other 5 patients underwent radical resection and postoperative radiotherapy in the first visit. Three patients survived more than 10 years, two survived for 4 years and no recurrence after 5 years respectively. The above data show that external auditory canal cancer can only get good early diagnosis and thorough treatment. Local resection easy to relapse, should not be used.
