简介：神经纤维瘤病（neurofibromatosis,NF）是由于基因缺陷导致神经嵴细胞发育异常而引起多系统损害的常染色体显性遗传病。NF虽为良性肿瘤,但可发生恶变和累及其他系统,临床较为少见。福建医科大学附属宁德市医院2012年12月21日收治NFⅠ型伴恶变患者1例。现结合文献复习,报道如下。

简介：目的研究肺癌患者的凝血功能与肿瘤病理类型及分期的关系,并探讨其临床意义.方法收集南京医科大学第一附属医院胸心外科2012年1月至2012年6月连续76例行手术治疗的肺癌患者,检测患者血浆组织因子（TF）、D-二聚体、血浆纤维蛋白原（FIB）、纤维蛋白原降解产物（FDP）水平及血小板（PLT）计数,按不同病理类型及术后分期对以上指标进行比较.结果Ⅲ期、Ⅳ期患者的血浆D-二聚体、TF水平明显高于Ⅱ期患者,差异有统计学意义（P＜0.05）.肺腺癌患者TF、D-二聚体水平明显高于肺鳞癌患者,差异有统计学意义（P＜0.05）.结论肺癌患者凝血功能与病理类型、肿瘤分期有关,早期发现并改善高凝状态,可能对肺癌预后有意义.

简介：随着检查手段的丰富、新型抗癌药物的快速研发以及多学科综合治疗的发展，乳腺癌（breastcancer，BCa）的检出率和治愈率已显著提高，总死亡率正逐年下降。然而，Bca患者之间存在明显异质性，即使临床分期或病理类型相同，采用同种治疗方案治疗时，

简介：目的对比分析分化型甲状腺癌不同手术方式术后主要并发症的情况。方法回顾性分析河北医科大学第二医院2004年1月至2012年1月经手术治疗的264例分化型甲状腺癌资料。结果患侧腺叶及峡部切除术77例,术后喉返神经损伤1例（占1.3%）,低钙血症1例（占1.3%）;患侧腺叶及峡部＋对侧大部切除术137例,术后喉返神经损伤4例（占2.9%）,低钙血症9例（占6.6%）;甲状腺全切术50例,术后喉返神经损伤2例（占4.0%）,低钙血症11例（占22.0%）。结论甲状腺全切术、患侧腺叶及峡部切除术与患侧腺叶及峡部＋对侧大部切除术术后喉返神经损伤率无统计学差异;甲状腺全切术术后低钙血症发生率明显高于患侧腺叶及峡部切除术与患侧腺叶及峡部＋对侧大部切除术。

简介：目的探讨LuminalA型乳腺癌的激素受体表达水平与绝经的相关性，进一步认识该类乳腺癌的生物学特性。方法回顾性分析江苏省肿瘤医院2009年1月至2012年10月收治的135例LuminalA型乳腺癌患者的雌激素受体（estrogenreceptor，ER）及孕激素受体（progesteronereceptor，PR）的表达水平（高表达（H）〉50％；低表达（L）≤50％），比较ER、PR的不同表达分组在绝经前后患者中的差异及ER、PR间的相关性。结果绝经前LuminalA型乳腺癌ER—H／PR-H表达最常见（63．8％）；ERH／PR—L表达在绝经后患者中最常见（51．1％），在绝经前少见（17．0％）。ER、PR的相关性在绝经前比绝经后更明显（P值：0．003VS．0．047）。结论绝经前后的LuminalA型乳腺癌患者存在ER、PR的不同表达的差异性分布，体内雌激素水平可能是引起差异的原因。

简介：目的探讨白蛋白结合型紫杉醇联合替吉奥（S-1）作为三线及以上方案治疗晚期非小细胞肺癌（NSCLC）的疗效和安全性.方法18例晚期NSCLC患者接受白蛋白结合型紫杉醇联合S-1治疗,具体方案为：白蛋白结合型紫杉醇125mg/m2,d1、d8;体表面积＜1.25m2：S-180mg/d,1.25m2～1.5m2：100mg/d,≥1.5m2：120mg/d,分2次口服,d1～d14;21天为1个周期,至少完成2个周期.根据RECIST标准评价其近期疗效及NCI毒性评价标准评价不良反应.结果18例NSCLC患者中无完全缓解（CR）病例,部分缓解（PR）4例,疾病稳定（SD）9例,疾病进展（PD）5例,有效率（RR）为22.2％（4/18）,疾病控制率（DCR）为72.2％（13/18）.中位无进展生存时间（PFS）为3.0个月.治疗相关毒副反应为骨髓抑制、脱发及周围神经毒性,均可耐受.结论白蛋白结合型紫杉醇联合S-1方案高效、低毒、使用方便,可为部分难治性晚期NSCLC患者三线及以上治疗提供又一选择.

简介：背景表浅型基底细胞癌通常的治疗手段并非外科手术,而多用药物局部治疗或光动力疗法,尽管大多认为光动力疗法疗效更好,但并未经临床对照研究证实。本研究即对比光动力疗法与局部应用咪喹莫特及局部应用氟尿嘧啶对表浅型基底细胞癌的疗效。方法本研究为单盲、
