摘要
选择1989年1月至1990年12月治疗前有CT检查的177例鼻咽癌,对咽旁间隙侵犯的临床意义进行评价,124例有咽旁间隙侵犯者中前区侵犯63例,后区侵犯61例。全组2年、4年无瘤生存率为73.8％和54.6％。咽旁间隙后区侵犯时颈淋巴结转移率86.9％,4年局控率和生存率为62.8％和43.4％,均比咽旁间隙无侵犯和(或)前区侵犯差(P<0.05)。咽旁间隙后区侵犯病例的治疗应进一步研究。
In 124 NPC patients admitted from Jan. 1989 through Dec. 1990, the influence of parapharyngeal extension of tumor on the outcome of NPC was evaluated. CT scans were performed before treatment as routine. 63 of 124 cases with parapharyngeal extension showed tumor invasion into the anterior space and 61 cases had tumor involving the posterior space. The overall 2- arid 4-year survivals without evidence of disease were 73. 8% and 54. 6%, respectively. With the posterior parapharyngeal space invaded, the neck metastasis rate was 86. 9%. The 4-year control rate and the 4-year survival rate were 62. 8% and 43. 4% which are inferior to those without parapharyngeal . involvement or invasion to the anterior parapharyngeal space only (P<0. 05). It is concluded that further study should be made on NPC cases with parapharyngeal involvement.
