目的 探讨宫颈癌骨转移相关因素。 方法 回顾分析2008年6月－2011年8月收治的352例宫颈癌患者的临床资料，其中鳞癌326例，腺癌26例；临床分期Ⅰ期60例、Ⅱ期184例、Ⅲ期90例、Ⅳ期18例。比较不同期别、不同病理类型、不同组织分级患者的骨转移情况。 结果 352例宫颈癌中有18例发现骨转移，转移率为5.1%；转移时间为3～48个月，2例于骨转移后1年内死亡。鳞癌326例，骨转移率为5.2%；腺癌26例，骨转移率为3.8%。Ⅰ、Ⅱ、Ⅲ和Ⅳ期患者的骨转移率分别为0.0%、3.8%、5.6%和33.3%，晚期与早期相比有统计学意义（P＜0.05）；高、中和低分化患者骨转移率分别为3.1%、3.1%和6.3%，高分化与中分化相比，差异无统计学意义（P＞0.05），低分化与高中分化相比差异有统计学意义(P＜0.05)。 结论 宫颈癌骨转移与宫颈癌临床分期、病理类型、细胞分级密切相关。在宫颈癌的治疗过程中，做到早发现、早治疗，可提高患者的治疗效果，延长生存时间。
ObjectiveTo systematically review the correlation between mTOR protein expression and different clinical pathological features as well as the response to radiotherapy and chemotherapy of cervical cancer. MethodsWe electronically searched databases including The Cochrane Library (Issue 1, 2015), PubMed, EMbase, CNKI, CBM, VIP and WanFang Data from inception to April 2015 to collect case-control studies investigating the correlation between mTOR protein expression and different clinical pathological features as well as the response to radiotherapy and chemotherapy of cervical cancer. Two reviewers independently screened literature, extracted data and assessed the risk bias of the included studies. Then meta-analysis was performed using RevMan 5.2 software. ResultsA total of 8 case-control studies involving 591 patients were included. Among these cases, 365 cases were in the cervical cancer group, 135 cases were in the cervical intraepithelial neoplasia (CIN) group, and 91 cases were in the normal cervix tissue group. The results of meta-analysis showed that:(1) Compared with the normal cervix tissue group, mTOR protein was overexpressed in the cervical cancer group (OR=24.14, 95%CI 4.47 to 130.35, P=0.000 2) and the CIN group (OR=4.71, 95%CI 2.15 to 10.33, P=0.000 1); Compared with the CIN group, mTOR protein was overexpressed in the cervical cancer group (OR=5.12, 95%CI 2.96 to 8.86, P<0.000 01). (2) Compared with the non-lymphnode-metastasis group, mTOR protein was overexpressed in the lymph node metastasis group (OR=3.29, 95%CI 1.61 to 6.69, P=0.001); Compared with the FIGO I group, mTOR protein was overexpressed in the FIGO Ⅱ group (OR=3.00, 95%CI 1.49 to 6.04, P=0.002); Compared with the radiotherapy and chemotherapy responsive group, mTOR protein was overexpressed in the non-response group (OR=15.64, 95%CI 3.17 to 77.15, P=0.000 7). In addition, there was no significant difference between the medium/high differentiation group and low differentiation group (OR=1.70, 95%CI 0.75 to 3.81, P=0.20). ConclusionmTOR protein expression is associated with cervical cancer, and mTOR protein overexpression was associated with lymph node metastasis, higher FIGO and non-response to radiotherapy and chemotherapy. Due to the limited quantity and quality of the included studies, the above conclusion needs to be further verified by more high quality studies.
目的:探讨平阳霉素/博来霉素联合顺铂(BP方案)、5氟尿嘧啶+异环磷酰胺联合顺铂(FIP方案)在宫颈癌新辅助化疗(Neoadjuvant Chemotherapy, NACT)的疗效及临床意义。方法:2004～2008年我院收治的Ib2-IIb期巨块型宫颈癌共62例,其中36例行BP或FIP方案化疗1～2个疗程后行根治性手术,为研究组;另26例直接行根治性手术,为对照组;术前评价NACT的疗效,并比较两组术中出血量、术后病理特征及并发症。结果:研究组36例患者术前进行NACT有效率为86％;术后病理检查示淋巴结阳性率,阴道切缘阳性率及宫旁累及率均较对照组低,差异有显著性。结论:利用BP,FIP方案对宫颈癌患者进行新辅助化疗有效、安全、经济,可缩小癌肿体积,增加手术切除率。
【摘要】 目的 探讨中晚期宫颈癌术前动脉灌注化疗栓塞的临床价值。 方法 选择2005年6月-2009年12月35例经阴道镜活检确诊为宫颈癌临床分期Ⅱa~Ⅲb期宫颈癌患者，术前行1次子宫动脉化疗栓塞，化疗药物为博莱霉素（BLM）+顺铂（DDP）+环磷酰胺（CTX），栓塞剂为超液化碘油加明胶海绵颗粒。介入治疗后14~20 d行子宫全切加淋巴结清扫术。观察动脉灌注化疗栓塞前后肿块的大小变化、术中肿块粘连状况及出血量的多少。 结果 经介入治疗后肿块缩小32例：完全缓解（CR）3例、部分缓解（PR）29例，肿块无变化（NC）2例，进展（PD）1例，治疗有效率为91.4%。31例选择了手术治疗，手术率为88.6%。术中肿块粘连状况：无粘连24例，轻度粘连6例，中度粘连1例。术中出血量：≤100 mL 7例，100~200 mL 18例，200~400 mL 6例。 结论 中晚期宫颈癌术前动脉灌注化疗栓塞能有效地提高肿瘤切除率，降低手术风险。【Abstract】 Objective To evaluate the clinical value of preoperative transarterial chemoembolization for advanced cervical cancer. Methods A total of 35 patients with pathologically proved cervical cancer (from stage Ⅱa to Ⅲb) from June 2005 to December 2009 received preoperative transarterial chemoembolization once. Bleomycin, cisplantin and cytoxan were infused via bilateral uterine arteries, followed by arterial emboliezation with super-liquefaction iodipin and gel foam particles as embolic agent. Radical surgery was performed on the patients after 14-20 days. Volume change of mass, accretion state and haemorrhagia amount during the operation were analyzed. Results The masses deflated in 32 cases: complete response (CR) in 3, and partial response (PR) in 29. No change (NC) was seen in 3 cases. The effective rate was 91.4%. In 31 cases who underwent the operation, the operability was 88.6%, in whom non-accretionin was in 24, light accretion was in 6 and medium accretion was in 1. Haemorrhagia amount was less than 100 mL in 11 cases, 100-200 mL in 21cases, and 200-1 400 mL in 3 cases. Conclusion Preoperative chemoembolization can elevate exairesis rate and depress the operative risk effectively.
Objective To assess the efficacy and safety of laparoscopic nerve-sparing radical hysterectomy (LNSRH) in treatment of early cervical cancer. Methods Such databases as CBM (1960 to September 2011), CENTRAL (1966 to September 2011), MEDLINE (1966 to September 2011), The Cochrane Library, EMbase (1974 to September 2011) and CNKI (1994 to September 2011) were searched on computer, and relevant magazines were also searched manually. Data were extracted and the quality was assessed after including studies according to exclusive criteria, then meta-analysis was conducted using RevMan 5.1 software. Results Total 7 studies involving 506 cases were selected, of which 255 cases were in the LNSRH group and the other 251 cases were in the laparoscopic radical hysterectomy (LRH) group. There were no differences between the two groups in age, body mass index, clinical stage, pathological type and histological grade. The results of meta-analysis showed that: a) The operative time of LNSRH was longer than LRH, with significant difference (P=0.02). But there was no significant difference in intraoperative bleeding between the two groups (P=0.69); b) The length of dissected parametrium of LNSRH was shorter than LRH with significant difference (P=0.02). But there was no significant difference in the length of dissected vagina (P=0.69); and c) The functional recovery of the bladder in the LNSRH group was better than LRH (Plt;0.000 01). Conclusion LNSRH is safe and feasible in effectively alleviating the postoperative dysfunction of the bladder in early cervical cancer as well as in improving the quality of life for patients. It is regarded as a new model of operation. Because it has just been put into practice within a short time, and there is lack of multi-center, large-sample, prospective controlled studies at present, so its radical effectiveness, long-term recurrence rate, survival rate, etc. have not yet been confirmed. More high quality studies are needed to provide important data of comparison between LNSRH and LRH.
目的:比较宫颈癌术后的三维适形放疗(3D-CRT)和调强放射治疗(IMRT)放射治疗计划的剂量学差异。方法:使用Elekta公司的PrecisePLAN Release2.11计划系统设计常规四箱形野(3D-CRT)和调强放疗(IMRT)计划。通过剂量体积直方图比较二者的放射物理参数,评价其应用价值.结果:IMRT计划中靶区平均剂量略高于3D-CRT计划中的相应值,其靶区适形度明显占优。同时,IMRT计划中的膀胱、直肠、小肠、股骨头等危险器官受到的平均剂量低于3D-CRT计划中的相应值,除右股骨头受到的平均剂量差异没有统计学意义,其它数据的差异都具有统计学意义。结论:对于宫颈癌术后患者的放射治疗,IMRT技术在保证肿瘤放射剂量的同时最大限度地减少了危险器官的照射剂量,减少了并发症的发生,应该更广泛地应用于临床。
