喉癌及下咽癌手术治疗进展

喉癌、下咽癌的治疗应遵循多学科综合治疗的原则。手术治疗只是其中的一个手段,如何综合应用现有的治疗手段,如放疗、化疗,是更好地治疗肿瘤,特别是晚期肿瘤的关键。本文仅就喉癌、下咽癌手术治疗进展加以论述。     

喉癌和下咽癌颈淋巴结转移临床对比分析

目的：探讨喉癌、下咽癌患者颈淋巴结转移的特点和分布规律。方法：对全喉切除术同期及复发后第1次行颈淋巴结清扫的129例喉癌、下咽癌患者的临床资料进行回顾性对比分析，研究不同类型的喉癌、下咽癌患者颈淋巴结的转移情况。结果：声门上型喉癌、下咽癌患者易发生早期淋巴结转移；下咽癌患者的转移淋巴结融合率高，颈静脉下区出现阳性淋巴结的比率高；声门上型喉癌、下咽癌患者原发病灶分化差的比率相对偏高；同期与复发后行颈淋巴结清扫的患者原发病灶分期差异无显著性意义。结论：对T2期及以上的声门上型喉癌及下咽癌患者，尤其当细胞分化比较差时，即使颈淋巴结阳性体征不明显亦应积极考虑颈淋巴结清扫问题，对下咽癌患者行颈淋巴结清扫时应考虑彻底清扫颈静脉下区的淋巴结。

Partial laryngeal surgery in recurrent carcinoma

With the growing acceptance of nonsurgical therapies for laryngeal squamous cell carcinomas (LSCCs), it has become important to delineate surgical salvage strategies for disease recurrences. Total laryngectomy is often recommended, but appropriately selected laryngeal recurrences may be treated successfully with partial laryngeal surgery: laryngeal function can be preserved with oncological efficacy. The main available studies dealing with partial laryngeal surgery in recurrent carcinoma were critically reviewed. The most appealing feature of salvage transoral laser surgery (TLS) is the opportunity to make tumor-tailored excisions without any reconstructive limitations and retaining the option to switch to open partial laryngectomy. A recent detailed review of 11 series found a pooled local control rate of 57% after a first TLS procedure. Supracricoid laryngectomy (SCL) seems to achieve good local control rates in selected cases of recurrent supraglottic-glottic carcinoma: one review considering seven series calculated that 85% of the patients treated with salvage SCL after radiotherapy experienced no local recurrence; and total laryngectomy after failure of salvage SCL afforded an overall local control rate of 65%. Neck dissection is mandatory in all cases of local LSCC recurrence with evidence of neck metastases, and routine elective neck dissection is recommended for recurrent supraglottic and transglottic cancers.     

Surgical voice restoration following ablative surgery for laryngeal and hypopharyngeal carcinoma

Surgical voice restoration is an important part of functional rehabilitation of patients following ablative surgery for laryngeal and hypopharyngeal carcinoma. The aim of this retrospective study was to assess the functional status with regard to speech of a cohort of 100 patients (age ranged 34-84 years), who underwent laryngectomy and laryngopharyngectomy over a 10-year period (1989-1999). Ninety-two patients consented to surgical voice restoration. Primary tracheoesophageal punctures were performed in 70 and secondary punctures in 22 (mainly after jejunal flap reconstruction). Nine patients were excluded from this analysis (seven patients died prior to assessment, one had the prosthesis removed at her request and one patient had insufficient follow-up). Tracheoesophageal speech was assessed in the remaining 83 patients using a rating scale measuring the number of syllables per breath, use of voice and intelligibility by non-professional listeners. Currently, Provox 2 valves are being used in the majority of patients. Overall tracheoesophageal speech results were good in 45/83 (54.2 per cent), average in 22/83 (26.5 per cent) and poor in 15/83 (18 per cent). One patient could not develop tracheoesophageal speech. The majority of laryngectomy patients had good speech but in patients who had complex reconstructions tracheoesophageal speech was mostly rated as average. Average to good speech in more than two-thirds of the cohort of patients show that surgical voice restoration is a highly successful and valuable technique to restore speech functions after ablative surgery for laryngeal and hypopharyngeal carcinoma.     

Conservation surgery for laryngeal and hypopharyngeal cancer

The charts of 173 patients treated by conservation laryngectomy and pharyngolaryngectomy were retrospectively reviewed. The patients treated by endoscopic laser resection were excluded of this study. Glottic carcinoma was diagnosed in 101 patients, supraglottic carcinoma in 44 patients, hypopharyngeal carcinoma in 24 patients and oropharyngeal carcinoma in 4 patients. The median follow-up period was 44 months, 84/101 glottic cancer, 34/44 supraglottic cancer, 23/24 hypopharyngeal cancer and 2/4 oropharyngeal cancer were staged as T1 and T2. A voice-sparing external approach was carried on in 20 patients with locally advanced tumor (T3-T4). At time of the last follow-up, 132 patients (77%) were alive when 41 patients (23%) died. Overall survival rates for patients treated for T1-T2 glottic cancer at 3, 5 and 10 years were 90, 90 and 78% respectively. Overall survival rates for patients treated for T1-T2 supralottic cancer at 3, 5 and 10 years were 73, 68 and 48% respectively. Overall survival rates for patients treated for T1-T2 hypopharyngeal cancer at 3 and 5 years were 74 and 37% respectively. The site of the primary tumor (glottic versus supraglottic or hypopharynx) showed significant impact on survival (P = 0.0025)). Regarding survival, T stage and N stage were not found statistically significant.
