纤维喉镜下Nd:YAG激光和直达喉镜下CO2激光治疗喉接触性肉芽肿疗效分析

目的研究纤维喉镜下Nd:YAG激光和直达喉镜下CO2激光治疗喉接触性性肉芽肿的方法,并比较其疗效。方法回顾性分析经组织病理确诊的64例喉接触性肉芽肿患者,28例采用全身麻醉气管插管,支撑喉镜在显微镜协同下用CO2激光切除病变,封闭创面;36例采用局部麻醉,纤维喉镜下引导光纤,用Nd:YAG激光切除病变。术后随访6个月以上。结果 64例喉接触性肉芽肿患者中,28例采用CO2激光切除,1次手术治愈率仅为21.83%,2次手术治愈率为28.57%,3次手术治愈率为10.71%,3次以上手术仍复发者为39.28%;36例采用Nd:YAG激光切除,1次手术治愈率为33.33%,2次手术治愈率为30.56%,3次手术治愈率为25.00%,3次以上手术仍复发者为11.11%。两者比较CO2激光切除病变复发率明显高于用Nd:YAG激光切除病变(P<0.05)。结论喉接触性性肉芽肿有强烈的复发倾向,仍以激光手术治疗为主,手术中尽可能减轻对喉的刺激,喉部局麻避免插管,对于治疗因插管引发的喉接触性肉芽肿极为重要;术后采取综合疗法,能缩短治疗时间,提高治愈率,减少并发症和不良反应。

Glottische Larynxkarzinome

BACKGROUND: Endoscopic laser resection is one treatment modality for early glottic carcinoma. Benefits are the preservation of laryngeal structure without tracheotomy, the short duration of treatment, low traumatisation and good functional results. METHODS: From 1989 to 1999, 143 patients with an isolated and previously untreated glottic squamous cell carcinoma were treated by CO2 endoscopic laser resection. The tumors were classified as carcinoma in situ (Tis) in seven cases, T1 tumor (T1N0M0) in 91 patients and T2 tumor (T2N0M0) in 45 cases. Median follow-up was 5 years. RESULTS: For the group of Tis and T1 carcinomas, 86 of 98 patients were free of recurrences. The 12 recurrences (12.2%) were treated by repeated laser surgery and laryngectomy (four patients). None of these patients died of tumor related causes. For patients with T2 carcinomas, the overall recurrence rate was 28.9% (13 patients). In six patients, a total laryngectomy had to be performed and one patient died because of tumor recurrence. The relapse free survival estimate using the Kaplan-Meier method was 87% for Tis and T1 carcinomas and 70% for T2 carcinomas. The overall laryngeal preservation rate was 95% for Tis and T1 carcinomas and 85% for T2 tumors. All recurrences occurred within 4 years of primary surgery. CONCLUSION: The results suggest that the oncological outcome after endoscopic laser surgery is comparable to conventional open partial resections.

CO2激光手术治疗声门型喉癌疗效分析

OBJECTIVE: To evaluate the curative effect of CO2 laser in treatment of glottic carcinoma. METHODS: Retrospective analysis of 217 cases of early glottic laryngeal carcinoma treated with laser surgery were carried out. Among these cases, Tis were 22 cases, T1a 108 cases, T1b 38 cases, T2 46 cases, T3 3 cases. 1 case being applied vocal cord excision due to failure of tumor exposure. The follow-up period was 3 to 9 years. RESULTS: Relapse were detected in 21 out of 217 cases of glottic laryngeal carcinoma after CO2 laser surgery under self-retaining laryngoscope. The recurrent rate was 9.7% (21/217). Recurrent ratio of T1a, T1b, T2, T3 were 5.6% (6/108), 21% (8/38), 13.0% (6/46), 1/3 respectively, with significant differences among groups (chi 2 = 6.102, P < 0.01). The recurrent rate was 21.6% of tumors offended the anterior commissure, versus 5.1%(8/157) with no involvement of anterior commissure (chi 2 = 13.64, P < 0.01). 217 cases received laser surgery as the only treatment, 201 cases were still alive. 4 failed to be followed-up(taken into dead number), 12 cases were dead. 3 year survival rate was 97.2%(211/217), 5 year survival rate was 89.4%(118/132). CONCLUSION: It was reliable to use laser surgery in treatment of early glottic laryngeal cancer. The advantages of it included lower complication rate and vocal function was well retained.     

Microinvasive Nd:YAG laser therapy of early glottic carcinoma and its effect on soluble interleukin-2 receptor, interleukin-2, and natural killer cells

OBJECTIVE: To investigate the effectiveness of microinvasive Nd:YAG laser therapy in human glottic Tis and T1 carcinomas, as well as its effect on the cellular immune function of the tumor-bearing hosts. STUDY DESIGN: We treated 34 patients with microinvasive Nd:YAG laser therapy and evaluated its effect on the cellular immune function of the host. METHODS: Thirty-four patients with glottic Tis or T1 squamous cell carcinoma were treated with fiberoptic laryngoscopic Nd:YAG laser surgery. Both before and after therapy, serum levels of soluble interleukin-2 receptor (SIL-2R) and interleukin-2 (IL-2), as well as natural killer (NK) cell activity, were determined by means of double-antibody sandwich technique, tritiated thymidine-deoxyribonucleoside incorporation, and iodine 125-uridine-deoxyribonucleoside release technique, respectively. RESULTS: All 34 patients tolerated the procedure well. A 3- to 7-year follow-up in a subgroup of 27 patients resulted in an estimated cure rate of 85.2% (23 of 27 patients). In all 27 patients with a regular follow-up, a subjective improvement of phonation was noted after therapy to various degrees. In 74% (20 of 27 patients), voice and speech subjectively recovered to almost normal levels. The post-therapy serum levels of SIL-2R were significantly declined (P <.001), whereas those of IL-2 and the NK activity were significantly elevated (P <.001) as compared with those detected before therapy. CONCLUSIONS: Therapy with fiberoptic laryngoscopic Nd:YAG laser surgery is simple, safe, effective and only minimally invasive for patients with glottic Tis or T1 carcinoma. At the same time, it has an immunoenhancing effect on its host.

Neodymium YAG Contact Laser in the Treatment of Cancer of the Mobile Tongue

The aim of this study was to evaluate the usefulness of a contact neodymium YAG laser for the treatment of squamous cell carcinoma (SCC) of the mobile tongue in 35 patients. The TNM stage and histologic grade were as follows: T1, n = 20; T2, n = 11; T3, n = 4; and N0, n = 33; N1, n = 2; G1, n = 20; G2, n = 10; and G3, n = 5. The surgical treatment consisted of a hemiglossectomy or resection with adequate margins in 28 cases, and an ipsilateral neck dissection was also performed in 7 patients. Radiotherapy to a mean tumor dose of 62-64 Gy and an elective dose of 50 Gy to the cervical lymph nodes was given to 14 patients. The radiotherapy was preoperative in 12 patients and postoperative in 2. Tongue resection was easily performed using the contact neodymium YAG laser, with a mean operation time of 31 min and intraoperative bleeding varying from negligible to 100 cm 3 . During postoperative follow-up no major complications occurred: cases with minor hemorrhage were easily controlled on the ward and 1 patient had a bleed on the 14th postoperative day necessitating hospitalization. The resection was histologically radical in all cases. During follow-up one patient had a local recurrence (T2N0, G3) and four failed in the neck (T1N0 G2, T1N0 G2, T1N0 G2, T2N0 G2), three of whom were successfully salvaged with a neck dissection and radiotherapy. One patient with osteoradionecrosis was diagnosed and treated curatively. Two patients died of their tongue cancer (T2N0 G3, T2N0 G2), 1 died from a second primary tumor (T2N0 G1) and 2 of intercurrent disease with no evidence of cancer; 30 patients (86%) are still alive with no evidence of disease. The function of the tongue in all patients in this sample was good to satisfactory. The major complaint was xerostomia in the irradiated patients. In conclusion, the contact neodymium YAG laser appears to be suitable for resection of T1-T2 SCCs of the oral tongue. In this limited patient sample T stage or grade did not predict failures in the neck. Biologic predictive markers need to be evaluated.     

64例下咽癌病人临床疗效的回顾分析

目的 :探讨下咽癌外科切除与修复手术的治疗效果。方法 :分析 1989年 1月～ 1995年 9月 6 4例下咽癌切除患者的手术方法、并发症、生存率等 ,其中保留喉功能的下咽癌切除患者 2 6例 ,未保留喉功能的下咽癌切除患者 38例。结果 :6 4例下咽癌患者手术后全部恢复了吞咽功能 ,并发症发生率 40 .6 % (2 6 / 6 4) ,以咽瘘最常见。2 6例保留喉功能的下咽癌切除术后拔管率 5 3.8% (14/ 2 6 ) ,3年和 5年生存率分别为 6 5 .4% (17/ 2 6 )和 5 0 % (13/ 2 6 )。38例喉全切除下咽癌患者 3年和 5年生存率分别为 5 2 .6 % (2 0 / 38)和 44 .7% (17/ 38)。保留喉功能和未保留喉功能两者 3、5年生存率比较没有显著差异 (P >0 .0 5 )。结论 :保留喉功能下咽癌手术适用于 T1 、T2 期的肿瘤及经过仔细选择部分 T3期肿瘤患者 ,不影响患者的长期生存率 ,同时可有效的提高患者的生存质量
