筛窦癌的临床分型:(1)前方型:骨破坏快,易侵犯前颅窝,此处以未分化癌为多,对放射治疗敏感。(2)中间型:此型最多,易向鼻腔发展,腺癌为多,放射治疗效果差,宜用手术或手术加放射治疗。(3)后方型:多向蝶窦和鼻咽顶发展,腺癌、扁平上皮癌均有,但后者居多。有转移者以转移到颈淋巴结者为多,远端转移以肺部多见。
The clinical classification of ethmoid sinus cancer: (1) Anterior type: Bone destruction is quick and easy to invade the anterior cranial fossa, where there are many undifferentiated carcinomas, which are sensitive to radiation therapy. (2) Intermediate: This type is most likely to develop into the nasal cavity. There are many adenocarcinomas and the effect of radiation therapy is poor. It is advisable to use surgery or surgery plus radiation therapy. (3) Posterior: Development of multi-sphenoid sinus and nasopharyngeal topography. Adenocarcinoma and squamous epithelial cancer are common, but the latter is predominant. There were more metastases to metastases to cervical lymph nodes and more common metastases in the lungs.
