    • 摘要: Objective To analyze the clinical characteristics,prognosis and molecular biological changes of tonsillar squamous cell carcinoma(TSCC).Methods Retrospective analysis of 61 TSCC cases treated from January 1999 to December 2012.Demographic data and clinical charts,including histologic grade of tumor,treatment and outcome of the patients,were reviewed.Human papillomavirus (HPV)-DNA were detected using SPF10-DNA enzyme immunoassay and LiPA genotyping method.Expressions of p16 and p53 proteins were examinated by immunohistochemistry.Survival rate was calculated with SPSS 19.0 software using the Kaplan-Meier method.Results There were 55 males and 6 females,with a median age of 57 years.Of the 61 TSCC,21 were with well differentiation,19 with moderate differentiation and 21 with poor differentiation,including 7 patients at stage Ⅱ,10 at stage Ⅲ and 44 at stage Ⅳ.HPV-positive rate of TSCC was 29.5% (18/61) and high-risk HPV-16 subtype accounted for 72.2% (13/18).The percentage of famel patients in HPV-positive TSCC was higher than HPV-negative TSCC(22.2% vs 4.7%).HPV-positive TSCC was more common in non-smoking patients (50.0% vs 79.1%,x2 =5,155,P =0.023) and non-drinking patients (27.8% vs 51.2%,x2 =4.346,P =0.037).HPV-positive TSCC mostly presented with high expression of p16 protein (88.9% vs 16.3%,x2 =28.481,P =0.000),and low expression of p53 protein(72.7% vs 46.5%,x2 =5.028,P =0.025).The prognosis of patients with HPV-associated TSCC was significantly better than non-HPV-associated TSCC,and The 3-year and 5-year overall survival rates of patients with HPV-positive TSCC were higher than those of patients with HPV-negative TSCC (87.7% vs 49.5% and 78.9% vs 33.0%,respectively).Conclusion HPV-associated TSCC had unique clinicopathological and molecular biological features,showing better prognosis compared to HPV-negative TSCC.%目的 总结分析人乳头状瘤病毒(human papillomavirus,HPV)相关扁桃体鳞状细胞癌(鳞癌)患者的临床病理特征、预后特点及分子生物学改变.方法 回顾性分析1999年1月至2012年12月期间中国医学科学院肿瘤医院收治的符合入组条件的61例扁桃体鳞癌患者的临床病理资料,应用HPV SPF10 PCR/DEIA检测和LiPA分型方法进行HPV-DNA检测及分型;采用免疫组织化学法检测p16及p53蛋白表达情况.采用Kaplan-Meier法计算生存率.结果 61例扁桃体鳞癌患者中,男55例,女6例;中位发病年龄57岁.肿瘤临床分期为Ⅰ期0例,Ⅱ期7例,Ⅲ期10例,Ⅳ期44例.肿瘤的分化程度为高分化21例,中分化19例,低分化21例.扁桃体鳞癌HPV总感染率为29.5%(18/61),男性14例,女性4例,其中HPV-16亚型占全部感染的72.2% (13/18).HPV相关扁桃体鳞癌女性患者比例高于非HPV相关扁桃体鳞癌(22.2%比4.7%),且更易发生于非吸烟及非饮酒患者(吸烟:50.0%比79.1%,x2=5.155,P=0.023;酗酒:27.8%比51.2%,x2=4.346,P=0.037).HPV相关扁桃体鳞癌p16蛋白多为高表达(88.9%比16.3%,x2=28.481,P=0.000),而p53蛋白多为低表达(72.7%比46.5%,x2=5.028,P=0.025).Kaplan-Meier法计算HPV相关扁桃体鳞癌3年和5年总生存率分别为87.7%和78.9%,明显高于非HPV相关扁桃体鳞癌的3年总生存率49.5%和5年生存率33.0%,差异有统计学意义(x2=9.139,P=0.003).结论 HPV相关扁桃体鳞癌具有特殊的临床病理特征及分子生物学改变,且预后显著好于非HPV相关扁桃体鳞癌.

    • 摘要: 目的 探讨P16免疫组织化学半定量评分在宫颈上皮内瘤变(CIN)进行分级诊断中的作用及意义;分析P16表达情况、人乳头瘤病毒(HPV)感染及亚型分布的关系.方法 ①运用免疫组织化学二步法对P16进行蛋白染色,半定量评分.②采用聚合酶链反应+膜杂交法同时检测常见21种HPV亚型.结果 P16阳性率随宫颈病变级别的升高而增强,两者密切相关(P<0.01),组间差异均具有统计学意义(P<0.01),对CIN病变的预测灵敏度高,特异性强.免疫组织化学半定量评分结果显示:P16在表达炎症组中为阴性,CINⅠ级多数表达为+和++;CINⅡ级多为++和+++;CINⅡ~Ⅲ级表达为+++;CINⅢ级为+++和++++.HPV总感染率为73.62%,随宫颈病变级别升高阳性率增高,HPV16型感染与宫颈CIN二级分类病变程度有统计学意义(P=0.002).随P16表达强度升高,HPV感染率随之增高.且HPV16型、58型、52型、31型、66型和高危混合型在P16阴性和阳性比较中差异有统计学意义(P<0.05).结论 P16免疫组织化学半定量评分能够客观地反映CIN病变的程度,P16检测对宫颈CIN病变合并HPV感染病例预后及转归具有一定的提示.%Objective To investigate the effect and significance of P16 semi-quantitative immunohistochemical score for the classification of cervical intraepithelial neoplasia (CIN), and to analyze the correlations among the expres-sion of P16 protein, human papillomavirus (HPV) infection and the distribution of HPV subtypes. Methods ①Protein P16 was determined by two-step immunohistochemical staining, and the semi-quantitative immunohistochemical score was obtained. ②Twenty-one common HPV subtypes were determined by PCR and membrane hybridization. Results The P16 positive rate increased along with higher level of cervical lesion, with significant correlation ( P<0.01), and statistical significance (P<0.01) between them, which had high sensitivity for the prognosis of CIN lesions, and strong specificity. The immunohistochemical semi-quantitative score showed that the expression of P16 was negative in the inflammation group, (100%). The expressions of CIN Ⅰ, CINⅡ, CINⅡ-Ⅲand CINⅢlevels were+and++, ++and+++, +++, and +++ and ++++, respectively. The total infection rate of HPV was 73.62%. The P16 positive rate in-creased along with higher level of cervical lesion. There was statistical significance between HPV16 infection and sec-ondary classification of cervical CIN lesions (P=0.002). The HPV infection rate increased along with the higher P16 expression intensity. There were statistically significant differences in HPV16, 58, 52, 31, 66, and high-risk hybrid between negative and positive P16 (P<0.05). Conclusion P16 semi-quantitative immunohistochemical score can ob-jectively reflect the degree of CIN lesions. The determination of P16 shows certain significance in the prognosis and outcome of cervical CIN lesions and HPV infection.

    • 摘要: Objective To determine the positive rate of HPV16/18DNA and P16 protein in benign and malignant breast tumors and to investigate the correlation of HPV16/18 infection with P16 expression and clinical pathological features of breast cancer.Methods Between January 2008 and December 2008, HPV16/18 DNA in situ hybridization and immunohistochemical study of P16 protein were performed for 35 cases of breast cancer tissues, 35 cases of breast cancer adjacent tissues, 30 cases of breast fibroadenoma and 30 cases of normal breast tissues surgically removed in Department of General Surgery, First Affiliated Hospital of Shanxi Medical University.The biological data obtained were then analyzed using the statistical analysis toolkit (SPSS11.5), and P≤0.05 was considered statistically significant.Results The positive rate of HPV16/18 expression was 71% in breast cancer tissues, which reached the level of statistical difference compared with those in breast fibroadenoma and normal breast tissues (P≤0.05).The expressions of HPV16/18 in breast cancer tissues were positively associated with armpit lymph node metastasis (r= 0.152,P=0.021), but not with menopause and tumor size.There was a negative correlation between the expressions of HPV16/18 and P16 in breast cancer tissues (r=-0.662, P=0.000).Conclusion HPV was shown to be highly expressed in breast cancer, which might be etiologically relevant in occurrence of breast cancer.Moreover, HPV infection was positively associated with armpit lymph node metastasis, and therefore could be a marker of progression and prognosis for breast cancer.HPV infection may also be negatively correlated with inactivation of P16, suggesting that interactions between the both may be involved in the occurrence and development of breast cancer.%目的 检测乳腺良恶性肿瘤中人乳头状瘤病毒(HPV)16,18DNA和P16蛋白的阳性率,分析HPVl6,18感染与抑癌基因P16蛋白表达的相关性以及HPVl6/18感染与乳腺癌临床病理特征的相关性.方法 对2008年1月至12月山西医科大学第一医院普外科手术切除的35例乳腺癌组织、35例癌旁组织、30例乳腺纤维腺瘤组织以及30例乳腺纤维瘤旁正常组织进行HPVl6,18DNA分子原位杂交和P16蛋白免疫组织化学检测.结果 乳腺癌组织中HPV16/18的阳性率为71%,与纤维瘤组织和瘤旁正常组织相比,差异均具有统计学意义;HPV16/18在乳腺癌组织中的表达与腋淋巴结转移呈正相关(r=0.152,P=0.021),与患者月经状况、肿瘤大小无关;HPV16/18DNA和P16蛋白在乳腺癌组织中的表达呈负相关(r=-0.662,P=0.000).结论 HPV在乳腺癌组织中高表达,对乳腺癌的发生具有病因学意义.HPV感染与乳腺癌发生腋窝淋巴结转移呈正相关,可以作为评价乳腺癌发展和预后的指标.HPV感染与抑癌基因P16的失活在乳腺癌中呈负相关,二者可能在乳腺癌的发病中相互作用,共同影响乳腺癌的发生发展.

    • 摘要: Objective To explore the significance of P16 and P53 as assistant biomarkers in diagnosis of ASC cannot exclude HSIL (ASC-H) by liquid-based cervical cytology. Methods Fifty-nine ASC-H patients were performed immunohistochemistry (IHC) of P16 and P53. PCR-reverse dot blot for classification of human papillomavirus (HPV), colposcopic examination and biopsy. The correlation among the results was then analyzed. Results Of the 59 ASC-H patients,the rates P16 and P53 positive expressions were mainly found in high grade squamous intraepithelial lesions (HSIL) or over, including 28 cases of HSIL and 5 cases of squamous carcinoma (SCC). Along with the elevated pathological rank of cervicitis, the positive rates of P16 and P53 were increased. High-risk HPVs were all found positive in 35 cases of HSIL or over. Both sensitivity and negativity predictive value of HSIL in ASC-H patients were 100%. Conclusion ASC-H highly indicates the existence of high grade-cervical lesion. There was a favorable consistency between the IHC results of P16 and P53 and HPV classification detective results, both of which could indicate that ASC-H patients should undergo the futher colposcopic examination and biopsy. However, the IHC of P16 and P53 might be more convenient and faster.%目的 评价P16和P53在宫颈液基细胞学诊断宫颈细胞学不典型鳞状细胞不除外上皮内高度病变 (ASC-H)中辅助检测的标记意义.方法 对59例ASC-H患者分别进行P16、P53免疫组织化学(IHC)检测、聚合酶链反应(PCR)-反向点杂交法进行人乳头瘤病毒(HPV)分型和阴道镜检查及活检,分析其结果之间的关系.结果 59例ASC-H中,P16、P53阳性者主要为鳞状上皮内高度病变(HSIL)及以上病变,包括28例HSIL和5例活检结果为宫颈鳞状细胞癌(SCC)的病例;随着宫颈病变级别的上升,P16、P53阳性率增高;35例高危型HPV阳性均为HSIL及以上病变,对ASC-H患者HSIL的敏感性及阴性预测值均为100%.结论 ASC-H高度提示高级别的宫颈病变存在;P16、P53的IHC结果与HPV分型检测结果具有良好的一致性,均可提示ASC-H患者应进一步行阴道镜检查及活检;但P16、P53的IHC检测更加方便、快速.
