宫颈癌淋巴结转移的分布具有一定的规律性,遵循由近及远的逐站式转移模式,先从盆腔淋巴结到髂总淋巴结,然后再到腹主动脉旁淋巴结,并可继续向上转移至锁骨上淋巴结,很少见跳跃转移的情况。术前诊断宫颈癌淋巴结转移的常用影像学检查方法包括计算机断层扫描(CT)、磁共振成像(MRI)、正电子发射计算机断层显像(PET/CT),各有优缺点。近年来术中前哨淋巴结检测逐渐成为热点,但是目前仍没有人明确指出识别前哨淋巴结可以替代系统的淋巴结切除术。应根据各自的特点,选择合适的检查方法,提高检测淋巴结转移的诊断符合率,选择合适的治疗方法,减少患者不必要的损伤和并发症。 相似文献

2018年国际妇产科联盟(International Federation of Gynecology and Obstetrics,FIGO)更新宫颈癌分期,将治疗前影像学诊断盆腔淋巴结转移定义为ⅢC1r期,腹主动脉旁淋巴结转移定义为ⅢC2r期。术前影像学检查评估盆腹腔淋巴结是否转移与诊疗方案的制定相关,影像学准确地判断盆腹腔淋巴结状态可以明确分期,让患者接受规范的诊疗。目前临床上影像学检查方法众多,常用检查有B超、盆腔磁共振成像(magnetic resonance imaging,MRI)、计算机体层摄影术(computed tomography,CT)、正电子发射体层摄影术(positron emission tomography,PET)/CT及PET/MRI。B超经济方便,但对淋巴结检出率过低;CT在国内使用广泛、检查速度快,扫描范围大,临床应用易于推广,但CT诊断缺乏统一的诊断标准,诊断价值不突出;MRI具有良好的组织分辨率、能同时实现功能成像,但存在检查敏感度不高的情况;PET检查准确性较其他影像学检查较高,但其敏感度较MRI及CT检查并无统计学上的差异。 相似文献

早期宫颈癌术中意外发现淋巴结转移,妇科医生可能采取两种治疗策略:放弃子宫切除术后进行根治性放化疗(PRT)或完成子宫切除术,然后进行辅助放疗(RHRT)。目前应如何选择仍存争议,本文总结了近30年对比性研究结果,发现PRT与RHRT两种治疗策略在生存率、复发率和不良事件发生率方面没有显著差异。但RHRT治疗后下肢淋巴水肿的报告更频繁。目前的指南更倾向于推荐PRT治疗。但目前大部分研究都是样本量较少的回顾性研究,应谨慎考虑结论,综合考虑预后、不良事件、生存质量等因素,与患者共同决策,制定个体化治疗策略。 相似文献

目的:研究调强适形放疗加后装放疗联合化疗治疗中晚期宫颈癌的临床疗效,探讨其临床意义。方法:选取2012年6月至2014年6月保定市第一中心医院放疗科收治的中晚期宫颈癌(IIb期、IIIa期和IIIb)患者121例,其中59例采用调强适形放疗联合化疗(IMRT组),62例采用三维适形放疗联合化疗(3D-CRT组)。比较两组患者的治疗和随访情况。结果:IMRT组的骨髓抑制发生率(32.2%vs 51.6%)、胃肠道反应发生率(42.4%vs 62.9%)、直肠反应发生率(27.1%vs 45.2%)均少于3D-CRT组,差异有统计学意义(P0.05)。IMRT组的泌尿生殖道损伤、放射性直肠炎和放射性膀胱炎发生率分别为18.6%、23.7%和16.9%,3D-CRT组分别为24.2%、25.8%和20.9%;两组比较差异均无统计学意义(P0.05)。随访3年,IMRT组的局部控制率高于3D-CRT组,差异有统计学意义(86.3%vs 70.1%,P0.05)。结论:相比三维适形放疗,调强适形放疗联合化疗治疗中晚期宫颈癌能提高肿瘤局部控制率,更好地保护危及器官,减少放疗副作用,具有重要的临床应用价值。 相似文献

Study Objective
To show the feasibility of the laparoscopic extraperitoneal approach for pelvic metastatic lymph node debulking in locally advanced cervical cancer.Design
A surgical video article (Canadian Task Force classification III).Setting
A university hospital.Patient
A 52-year-old patient presented with stage IIA2 cervical adenocarcinoma according to Fédération Internationale de Gynécologie et d'Obstétrique classification. During the physical examination, a 45-mm tumor was discovered. Positron emission tomographic imaging was positive for hypermetabolic enlarged lymph nodes in the left external iliac region of 1.4-cm size and an standardized uptake value of 21 and in the right obturator region of 1.3-cm size and an standardized uptake value of 7.1; no aortic nodes were found using the imaging procedures. Before chemoradiation therapy, she underwent extraperitoneal aortic lymph node dissection for surgical staging at Vall d'Hebron University Hospital, Barcelona, Spain. Pelvic lymph node debulking was proposed to confirm positivity and, if so, to adjust the radiotherapy field and reduce lymph node radioresistance 1, 2.Interventions
After a complete extraperitoneal aortic infrarenal lymph node dissection as described by Querleu et al [3], the presacral space is created to expose the iliac vessels. The enlarged lymph nodes are identified and dissected using blunt dissection, monopolar energy, and a vessel sealing device.Measurements and Main Results
There were no intraoperative or postoperative complications. The anatomopathologic study confirmed positivity for adenocarcinoma metastasis in 3 pelvic nodes and 2 of 29 aortic nodes.Conclusion
Laparoscopic debulking of enlarged pelvic lymph nodes via the extraperitoneal approach is a feasible procedure. It can be performed as an extension of extraperitoneal aortic lymphadenectomy in selected patients with locally advanced cervical cancer. 相似文献12.

淋巴结转移作为宫颈癌和子宫内膜癌的主要转移途径,是影响其预后的重要因素。在治疗前和治疗过程中如何检测和评估这2种恶性肿瘤的盆腔淋巴结状态仍处于初步探索阶段。目前检测淋巴结状态的方法有超声检查、计算机断层扫描、磁共振成像(MRI)、正电子发射计算机断层显像(PET-CT)和前哨淋巴结活检定位等。不同检查方法的原理不同,其敏感度、特异度和准确度等方面各有优劣。随着影像学技术及显像生物制剂的发展,淋巴结状态检测已由单纯形态学向功能学转变。彩色多普勒超声、弥散加权成像及PET-CT等均在传统影像学技术上进一步提高了敏感度和特异度,其中PET-CT和功能性MRI在检测的敏感度、特异度和准确度等方面尤其具有优势;显像生物制剂通过不断发展,已逐渐细化为针对淋巴结内肿瘤细胞代谢、血管和淋巴回流等三方面的特异性淋巴造影剂。 相似文献

Background
Despite institutional studies that suggest that radical hysterectomy for cervical cancer is well tolerated in the elderly, little population-level data are available on the procedure’s outcomes in older women. We performed a population-based analysis to determine the morbidity, mortality, and resource utilization of radical hysterectomy in elderly women with cervical cancer.Methods
Patients recorded in the Nationwide Inpatient Sample with invasive cervical cancer who underwent abdominal radical hysterectomy between 1998and 2010 were analyzed. Patients were stratified by age: < 50, 50–59, 60–69, and ≥ 70 years. We examined the association between age and the outcomes of interest using chi square tests and multivariable generalized estimating equations.Results
A total of 8199 women were identified, including 768 (9.4%) women age 60–69 and 462 (5.6%) women ≥ 70 years of age. All cause morbidity increased from 22.1% in women < 50, to 24.7% in those 50–59 years, 31.4% in patients 60–69 years and 34.9% in women > 70 years of age (P < 0.0001). Compared to women < 50, those > 70 were more likely to have intraoperative complications (4.8% vs. 9.1%, P = 0.0003), surgical site complications (10.9% vs. 17.5%, P < 0.0001), and medical complications (9.9% vs. 19.5%, P < 0.0001). The risk of non-routine discharge (to a nursing facility) was 0.5% in women < 50 vs. 12.3% in women ≥ 70 (P < 0.0001). Perioperative mortality women ≥ 70 years of age was 30 times greater than that of women < 50 (P < 0.0001).Conclusion
Perioperative morbidity and mortality are substantially greater in elderly women who undergo radical hysterectomy for cervical cancer. Non-surgical treatments should be considered in these patients. 相似文献18.

Study Objective
To compare the use of robotic radical hysterectomy (RRH) and abdominal radical hysterectomy (ARH) in the United States, with secondary outcomes of perioperative complications, hospital length of stay (LOS), immediate postoperative mortality, cost and a subanalysis compared with laparoscopic radical hysterectomy (LRH).Design
Retrospective cohort study (Canadian Task Force classification II-2).Setting
Data from the National Inpatient Sample (NIS), a government-funded database of hospitalization in the United States.Patients and Interventions
All women with cervical cancer undergoing RH between 2008 and 2015 in the United States and included in the NIS database.Measurements and Main Results
Trends in surgical modality, baseline characteristics, LOS, perioperative outcomes, mortality, and hospital charges were compared between RRH and ARH. Regression models were adjusted for baseline characteristics. Among 41,317 women with cervical cancer, 3563 underwent RH, including 21.0% with a robotic procedure, 6.5% with a laparoscopic procedure, and 72.5% with open surgery. The annual rates of ARH declined significantly over the study period, whereas those of RRH increased. Baseline characteristics were comparable between the RRH and ARH groups. Compared with the ARH group, women undergoing RRH had a lower rate of cumulative postoperative complications (18.16% vs 21.21%; odds ratio [OR], 0.81; 95% confidence interval [CI], 0.6–1.0; p?=?.05), including lower rates of wound infection (0.27% vs 1.82%; OR, 0.14; 95% CI, 0.03–0.6; p < .01), sepsis (0.27% vs 1.20%; OR, 0.22; 95% CI, 0.05–0.9; p?=?.03), fever (1.87% vs 4.06%; OR, 0.44, 95% CI, 0.3–0.8; p < .01), and ileus (2.8% vs 9.13%; OR, 0.28; 95% CI, 0.12–0.4; p < .01). The LOS was significantly shorter in the RRH group (median, 2 days vs 4 days; p < .01). The total median hospitalization charge was $47,218 for the RRH group, compared with $38,877 for the ARH group (p < .01).Conclusion
RRH is being increasingly performed in the United States and is associated with shorter LOS and less postoperative morbidity; however, long-term oncologic outcomes require additional attention. 相似文献19.
目的:探讨顺铂对小鼠宫颈癌局部CD8~+T细胞的影响及可能机制。方法:建立TC-1肿瘤细胞C57BL/6小鼠模型,分为对照组(4只)和顺铂组(4只),对照组给予磷酸盐缓冲溶液(PBS)100μl,顺铂组给予顺铂5 mg/kg,两组均腹腔注射,3天1次,共2次。免疫组化方法检测两组肿瘤组织中CD8阳性T细胞(CD8~+T)、程序性凋亡配体1(PD-L1)的表达,并对小鼠宫颈癌组织中CD8~+T细胞与PD-L1表达的相关性进行分析,同时采用流式细胞仪检测并比较两组脾单核淋巴细胞中CD4~+CD25~+T调节细胞(Treg)数量比例。结果:①顺铂组模型小鼠宫颈癌组织中CD8~+T表达的MOD值为3.24±0.39明显低于对照组4.70±0.28,差异有统计学意义(P0.05);顺铂组PD-L1表达的MOD值为7.65±1.82高于对照组2.89±0.70,差异有统计学意义(P0.05)。②小鼠肿瘤组织中CD8~+T细胞与PD-L1表达呈负相关(r=-0.61,P0.05)。③顺铂组小鼠脾脏内单核淋巴细胞中Treg细胞数量(71.50±4.04)%低于对照组(87.00±6.06)%,差异有统计学意义(P0.05)。结论:顺铂可增加宫颈癌组织PD-L1表达,减少宫颈癌组织局部CD8~+T细胞数量,抑制机体免疫内环境,并且顺铂对机体免疫的抑制作用可能并不来源于对Treg细胞的影响。应用PD-L1抗体阻断顺铂诱发的PD-L1表达可能可促进顺铂的化疗效果。 相似文献
