The 5-year survival rate of these patients was 30%. In 111 patients who had tumor invasion of the orbital floor 88 underwent radical surgery with orbital exenteration and 23 had their orbital contents preserved. If orbital exenteration was performed, the 5-year survival rate was 27.3% (24 / 88) and the rate of recurrence within the orbit was 12.5%. In patients with preservation of the orbital contents, the corresponding rates were 34.8% (8 / 23) and 8.6% respectively (P = 0.65). Histological study af ter maxillectomy with orbital exenteration showed that in 95% of 65 specimens (62 / 65) invasion of the orbit was limited. These tumors could be completely resected by total maxillectomy with limited removal of the periorbital tissues after preoperative radiotherapy. We conclude that after preoperative radiation, the eyeball could be safely preserved in most selected patients with maxillary sinus carcinoma invading the orbital floor.展开更多
目的:通过检测MCM7和HPV在上颌窦鳞癌(squamous cell carcinoma of the maxillary sinus,MSSCC)中的表达,探讨其在MSSCC发病机制中的作用及临床意义。方法:采用免疫组织化学方法检测MSSCC(实验组)、癌旁组织(癌旁组)和下鼻甲黏膜组织(...目的:通过检测MCM7和HPV在上颌窦鳞癌(squamous cell carcinoma of the maxillary sinus,MSSCC)中的表达,探讨其在MSSCC发病机制中的作用及临床意义。方法:采用免疫组织化学方法检测MSSCC(实验组)、癌旁组织(癌旁组)和下鼻甲黏膜组织(对照组)中的MCM7及HPV的表达,应用SPSS 22.0软件包对数据进行统计学分析。结果:(1)MCM7在癌旁组和对照组上皮中大部分位于基底层,而其在MSSCC中呈弥散分布。MCM7在对照组(P=0.000)、癌旁组(P=0.000)和实验组(P=0.000)中的表达水平逐渐增高。(2)MCM7的表达仅与肿瘤分化程度有关(P=0.030),并且随着分化程度的下降,MCM7的表达水平逐渐增高。(3)伴HPV感染的细胞无论在对照组、癌旁组或实验组中分布均无明显规律。HPV在对照组、癌旁组及实验组患者中的感染率分别为40.00%(4/10)、95.65%(22/23)和78.57%(33/42)。(4)HPV感染与颈淋巴结转移有关(P=0.015),而与患者性别(P=1.000)、年龄(P=0.332)、吸烟(P=0.536)、临床分期(P=0.806)及肿瘤分化程度(P=0.489)无关。(5)在实验组中,伴HPV感染者,MCM7表达水平显著高于未感染者(P=0.007),且呈正相关关系(rs=0.317,P=0.041)。结论:MCM7和HPV可能与MSSCC的发生、发展有关,可能对患者的临床治疗及预后判断具有重要指导意义;MCM7异常表达可作为筛查HPV感染病例的良好临床病理学指标。展开更多
