作者等应用CO_2激光手术治疗喉癌55例,其中22例单用激光,30例激光并用放疗(6000 r),3例放疗后复发者行激光手术。除6例为T_2外,余为T_(1a)、T_(1b)及T(?),皆无局部及远位转移,均为鳞癌。1例局麻下经喉裂开手术,余均在直接喉镜下采用显微手术对癌肿进行切除或气化。治疗后随访:1年内者29例,1～2年10例,2～3年6例,3～4年6例,4～5年4例。单用激光手术的22例,复发8例。复发:多在1年内出现,常发生于病变范围广泛而切除较浅者。对其中3例再次单用激光手术,2例激光并用放疗,1例行喉部分切除,1例喉全切除,术后均
The authors used CO 2 laser surgery to treat 55 cases of laryngeal cancer, including 22 cases of laser alone, 30 cases of laser radiation therapy (6000 r), 3 cases of recurrence after radiotherapy laser surgery. Except for 6 cases of T2, the remainder were T_(1a), T_(1b), and T(?), and there were no local or distant metastases, and both were squamous cell carcinoma. One patient underwent laryngeal debridement under local anesthesia, and all underwent microsurgical resection or gasification of the cancer under direct laryngoscopy. Follow-up after treatment: 29 cases in one year, 10 cases in 1 to 2 years, 6 cases in 2 to 3 years, 6 cases in 3 to 4 years, and 4 cases in 4 to 5 years. There were 22 cases with laser surgery alone and 8 cases with recurrence. Recurrence: More often occurs within 1 year, and it often occurs in patients with extensive lesions and shallow resection. In 3 cases, laser surgery was performed again, 2 lasers were treated with radiotherapy, 1 was partial laryngectomy, and 1 was total laryngectomy.
