Squamous cell carcinoma (SCC) in the pharyngoesophageal junction (PEJ) with concomitant involvement of both the hypopharynx and cervical esophagus occurs rarely and poses a challenge in treatment. Data regarding the long-term result of aggressive surgical management was lacking.
Forty-one consecutive patients were treated with total pharyngolaryngo-esophagectomy (PLE) and reconstruction between 1984 and 2002. The clinicopathological parameters and prognostic data were analyzed.
The surgery carried a postoperative mortality rate of 9.8%. The overall median survival was 18.5 months, with a 31.5% 5-year survival rate. By multivariate analysis, patients with major tumor localization in the hypopharynx had significantly favorable prognosis (median survivals for hypopharyngeal versus esophageal localization, 37.2 versus 7.1 months, P = 0.043). The administration of adjuvant radiotherapy and tumor size less than 5 cm also contributed to a better outcome (P = 0.001 and P = 0.037, respectively).
An aggressive surgical approach with total PLE in conjunction with adjuvant radiotherapy represents a feasible option for treatment of advanced SCC simultaneously involving the hypopharynx and cervical esophagus, given the major tumor localization in the hypopharynx. On the other hand, radical surgery for those with major esophageal localization or with tumor size larger than 5 cm yielded ominous results and warrants further justification.
下咽食管交界处(PEJ)的鳞状细胞癌(SCC)同时累及下咽和颈段食管的情况罕见,治疗颇具挑战。缺乏关于积极手术治疗长期结果的数据。
1984年至2002年间,连续41例患者接受了全下咽-喉-食管切除术(PLE)及重建术。分析了临床病理参数和预后数据。
手术的术后死亡率为9.8%。总体中位生存期为18.5个月,5年生存率为31.5%。多因素分析显示,肿瘤主要位于下咽的患者预后明显较好(下咽与食管定位的中位生存期分别为37.2个月和7.1个月,P = 0.043)。辅助放疗的应用以及肿瘤大小小于5 cm也有助于取得更好的结果(分别为P = 0.001和P = 0.037)。
鉴于肿瘤主要位于下咽,积极的手术方法联合全PLE及辅助放疗是治疗同时累及下咽和颈段食管的晚期SCC的可行选择。另一方面,对于肿瘤主要位于食管或肿瘤大小大于5 cm的患者,根治性手术结果不佳,需要进一步论证。
