摘要
目的研究神经营养因子受体p75(p75^NTR)在人食管鳞癌细胞中的表达。方法应用免疫组织化学法检测100例人食管鳞癌样本中p75^NTR的表达情况,分析其与患者年龄、性别、肿瘤直径、淋巴转移、病理分化程度、3年存活率的关系。结果100例患者中p75^NTR阳性率为69.0%(69/100),在食管鳞癌组织中p75^NTR阳性和阴性表达患者年龄、性别、肿瘤直径、病理分化程度,差异有统计学意义[(61±7)岁比(56±8)岁,阳性表达率男性79.7%(47/59)比女性53.7%(22/45)、阴性表达男性占比38.7%(12/31)比女性占比61.3%(19/31),(4.6±1.1)cm比(3.2±1.4)cm,病理分化程度:高分化44.9%(31/69)比9.7%(3/31)、中分化50.7%(35/69)比71.0%(22/31)、低分化4.3%(3/69)比19.4%(6/31),P〈0.05],淋巴转移差异无统计学意义(P〉0.05)。结论p75^NTR在食管鳞癌患者中表达程度不同,高表达患者病理分化差,3年存活率低;p75^NTR在食管鳞癌发病过程中可能起重要的作用,其表达对判断入食管鳞癌临床预后有指导作用。
Objective To study the expression of neurotrophin receptor p75 (p75^NTR) in human esophageal squamous carcinoma. Methods Immunohistoehemistry was used to measure the expression of p75^NTR in pathological paraffin specimens from 100 patients with esophageal squamous carcinoma. The correlations between p75^NTR expression and age, gender, tumor diameter, lymph node metastasis, pathological differentiation, 3 years survival rate were analyzed. Results The total expression rate of p75^NTR was 69. 0% (69/100). The age, tumor diameter, degree of pathological differentiation was significantly different between patients with positive expression of p75^NTR and patients with negative expression of p75NTR [(61 ±7) years old vs (56 ± 8) years old; positive expression male 79.7% ( 47/59 ) vs female 53.7% ( 22/41 ), negative expression proportion male 38.7% ( 12/31 ) vs female 61.3% ( 19/31 ) ; (4. 6 ± 1.1 ) cm vs (3.2 ± 1.4) cm; high differentiation 44. 9% (31/69) vs 9. 7% (3/31), middle differentiation 50. 7% (35/69) vs 71.0% (22/31), low differentiation 4. 3% (3/69) vs 19.4% (6/31)] (P 〈 0.05), while the incidence of lymph node metastasis was not significantly different ( P 〉 0. 05 ). Conclusions The expression of p75 NTR in esophageal squamous carcinoma is higher in patients with poorly pathological differentiation tumor, with lower 3-year survival rate; p75^NTR might play an important role in esophageal squamous carcinoma and might be a valuable marker in predicting prognosis.
