乳腺癌前哨淋巴结探测的临床应用研究

乳腺癌的手术治疗已有100多年的历史,起初人们认为乳腺癌是局部疾病,因而手术占据着治疗的主导地位,且手术范围越做越大.近年来,随着对乳腺癌生物学行为的深入了解,乳腺癌综合治疗水平不断提高,同时由于现代医学模式的转变,对乳腺癌本身的认识和治疗上的观念也有了很大变化.目前普遍认为清除阴性淋巴结对预后毫无益处[1].按传统观念施行根治术清扫腋窝淋巴结(axillary lymph node dissection,ALND)会带来一些严重的并发症:同侧上肢疼痛、上举困难、淋巴水肿、肢体麻木等,Aitken等[2]报告为10%～60%,徐宏等[3]报告上肢肿胀发生率为7.9%,而前哨淋巴结活检可以减少或避免这些并发症[4].因此,乳腺癌病人手术方式选择的原则是在治疗效果相同的前提下,采用最简单、损伤少、副作用小、并发症少的方式.乳腺癌前哨淋巴结活检(sentinellymph node biopsy,SLNB)技术是乳腺外科领域的一个极具意义的进展,也是当前乳腺外科研究领域的一个热点[5,6].

白血病患者造血干细胞移植前单次全身照射的预后分析

Objective To analyze the prognostic factors of patients with leukemia treated with single fraction total body irradiation (SFTBI) followed by hernatopoietic stem cell transplantation (HSCT).Methods From January 2001 to September 2008, 102 patients received HSCT. The differences of the survival rate, relapse rate and incidence of interstitial pneumonia (IP) between groups regarding different genders, ages, pathological types, transplantation methods and TBI parameters were compared and the factors related with the survival rate, relapse rate and incidence of IP were analyzed. Results The followup time ranged from 15 to 1482 days (median, 406 days). The follow-up rate was 95.1%. 86 and 55patients were followed up more than one year and three years. The 1-and 3-year survival rates were 59.0%and 44.0%. In univariate analysis, the 3-year survival rate was signifcantly different between the groups with and without relapse before transplantation (20% vs. 55%, χ2 = 6.33, P = 0. 012), allogeneictranplantation versus autologous tranplantation (39% vs. 68%, χ2 = 8.06, P = 0.005), grade 3 or more acute graft versus host disease (aGVHD) and grade 0 -2 aGVHD (0% vs. 54%, χ2 = 7.52, P = 0.006),with and without relapse after transplantation (19% vs. 58%, χ2 = 10.13, P =0.001), with and without IP (23% vs. 58%, χ2 =8.35, P=0.004). Multivariate analysis showed that grade 3 or more aGVHD was the only statistically significant prognostic factors (χ2 = 12. 74 ,P =0. 000). The l-and 3-year relapse rateswere 30. 0% and 50. 0%. The incidence of relapse was obviously higher in the group with relapse before transplantation than that without (47% vs. 16%, χ2 =7. 32, P=0. 007). Multivariate analysis showed thatrelapse before transplantation was a significant factor predicting relapse after transplantation (χ2 = 9. 39,P =0. 020). The cumulative incidence of IP was 35.0%. The incidence of IP was different between groups with dose homogeneity > 3% and ≤ 3% (27% vs. 4%, χ2 = 5. 21, P = 0. 023), with and without acute parotitis (34% vs. 3%, χ2 = 14. 15, P= 0.000), allogeneic transplantation group and autologous transplantation group (31% vs. 8%, χ2= 7.70, P= 0.006). Multivariate analysis showed that transplantation methods, acute parotitis and dose homogeneity were statistically significant factors in predictingIP (χ2 = 10. 08 , 10. 08 and 7.69 , P = 0. 002 , 0. 002 and 0. 010 , respectively) . Conclusions Patients who develop grade 3 or higher aGVHD have poor prognosis. Dose homogeneity influences the incidence of IP. Patients undergoing allogeneic transplantation are apt to have IP. Acute parotitis is related with IP and might be a predictor.     

两种质子泵抑制剂治疗幽门螺杆菌感染活动性胃溃疡的药物经济学评价

目的：应用药物经济学原理分析泮托拉唑与兰索拉唑治疗幽门螺杆菌（ Hp ）感染活动性胃溃疡成本-效果,寻找最佳治疗方案。方法：选择符合标准的患者100例,随机分为A组和B组各50例,A组应用泮托拉唑,B组应用兰索拉唑,其余治疗方案二者相同,疗程结束进行疗效评价。结果：A组患者临床治愈率80．00％,B组溃疡愈合率80．00％,差异无统计学意义（ P＞0．05）。 A组患者成本-效果比（C/E）为4．81,明显低于B组的5．81,增量成本-效果比（ΔC/ΔE）为68．33;敏感度分析A组患者C//E为4．33,明显低于B组的5．25,ΔC//ΔE为66．85。结论：泮托拉唑治疗幽门螺杆菌感染活动性胃溃疡较兰索拉唑具有更高的药物经济学价值。     

血清tPSA、fPSA、fPSA／tPSA在前列腺癌诊断中的临床价值

目的：探讨血清tPSA、fPSA、fPSA／tPSA在前列腺癌诊断中的临床价值。方法：用化学发光法检测前列腺癌（PCA）与良性前列腺增生（BPH）患者血清tPSA、fPSA、fPSA／tPSA的比值。结果：PCA组和BPH组血清tPSA、fPSA、fPSA／tPSA比值比较,差异有统计学意义（P〈0．05）。结论：当浓度在4～10ng/mL范围内因PCA与BPH有交叉．fPSA与tPSA联合检测得到fPSA／tPSA比值有利于鉴别此组病人,更适合用于临床PCA的诊断。
