作者等报告12例筛窦癌的治疗经验,术前用放疗,后用手术切除。男性病人10例,女性2例。本组腺癌占6例(50％)、低分化或未分化癌3例、乳头状圆锥细胞瘤(Ringertz氏瘤)2例、鳞癌仅1例。未分化癌多发于青年病人,本组3例分别为17、27及37岁。从以上可见筛窦中的腺癌较多,此点与上颌窦癌不同,后者以鳞癌占多数。关于筛窦癌的治疗,目前以手术切除为主,或手术与放疗(术前或术后)的联合治疗。很少单用放疗作为治愈方法,仅用于晚期病人的姑息疗法,或用于因种种原因不能进行手术者。作者采用联合治疗法,常规方法为术前放疗,4～5 The authors reported 12 cases of ethmoid sinus cancer treatment experience, preoperative radiotherapy, and surgical resection. There are 10 male patients and 2 females. In this group, 6 cases (50%) of adenocarcinomas, 3 cases of poorly differentiated or undifferentiated carcinomas, 2 cases of papillary cell tumors (Ringertz’s neoplasms), and 1 case of squamous cell carcinoma. Undifferentiated carcinomas are mostly present in young patients. The three cases in this group were 17, 27 and 37 years old. From the above, there are more adenocarcinomas in the ethmoid sinus, which is different from the maxillary sinus cancer, which accounts for the majority of squamous cell carcinomas. With regard to the treatment of ethmoid sinus cancer, surgical resection is currently the main method, or combined surgery and radiotherapy (preoperative or postoperative). Rarely used radiotherapy alone as a cure, only for palliative care in advanced patients, or for those who cannot perform surgery for a variety of reasons. The authors used a combination therapy, the conventional method for preoperative radiotherapy, 4 ~ 5
