淋巴结转移是宫颈癌肿瘤细胞转移的最早特征,宫颈癌患者局部淋巴结状况直接影响患者的预后并决定着辅助治疗方案的制定。然而对患者盆腔所有淋巴结进行评估是一件十分繁杂的事情,前哨淋巴结(SLN)能反映整个盆腔淋巴结的转移状况,其研究使大多数早期宫颈癌患者避免不必要的盆腔淋巴结清扫术。目前常用的淋巴结识别方法有染料法、放射性核素示踪法及联合法。淋巴结微转移检测法(如:免疫组化法、连续切片法、鳞状细胞癌抗原检测及淋巴结HPV检测法等)能提高SLN的诊断准确性。  相似文献

前哨淋巴结是原发肿瘤区域淋巴引流的第一站,是最早发生肿瘤转移的部位。前哨淋巴结定位有染料法、核素法、联合法3种方法,对前哨淋巴结进行病理连续切片和免疫组织化学染色提高了微小转移灶的检出率,进而能有效判断淋巴结的转移情况。前哨淋巴结在宫颈癌的应用尚处在起步阶段。  相似文献

前哨淋巴结能准确预测盆腔淋巴结的转移状态,应用生物活性染料法、放射性核素示踪法或两者联合应用对前哨淋巴结进行定位,通过细胞印记法、病理连续切片、免疫组织化学染色及RT-PCR技术检测提高其阳性检出率,特别是宫旁淋巴结,有利于制定宫颈癌患者个体化治疗方案。目前快速准确检出前哨淋巴结有待于进一步发展。  相似文献

淋巴结转移与否是判断早期宫颈癌患者预后的独立危险因素和术后是否需要辅助治疗的依据。早期宫颈癌淋巴结转移率较低,大多数患者因无盆腔淋巴结转移而不能从全盆腔淋巴结清扫术中受益。若通过前哨淋巴结(sentinel lymph node,SLN)检测来准确评估早期宫颈癌盆腔淋巴结转移状态,则可以用SLN活检技术替代系统淋巴结清扫术减少手术并发症。虽然目前由于各种原因该项技术未能被临床广泛应用,但纳米炭(carbon nanoparticle,CNP)的出现为其提供了新的契机。CNP具有淋巴系统趋向性和吸附抗癌药物等特点,能在淋巴管、淋巴结高密度且长时间聚集,有利于指导恶性肿瘤的淋巴结清除及淋巴化疗。综述运用CNP混悬液在术前标记早期宫颈癌SLN的可行性,使SLN活检技术替代系统淋巴结清扫术成为可能。  相似文献

目的 探索子宫颈癌根治术中淋巴显影和前哨淋巴结识别的方法及其可行性,评价前哨淋巴结预测盆腔淋巴结有无肿瘤转移的准确性。方法 应用染料法对20例宫颈癌患者(临床分期为Ib期3例、Ⅱa期12例、Ⅱb期5例)在根治术中于宫颈肿瘤周围的正常组织中分4点(3、6、9、12点处)注入美蓝或专利蓝溶液4ml,识别和定位蓝染的淋巴结(即前哨淋巴结),然后再按常规行盆腔淋巴清扫术,所有淋巴结一起送病理检查。结果 20例宫颈癌患者中淋巴管有蓝色染料摄取者18例,共有蓝染淋巴结33枚,其中左侧15枚,右侧18枚,前哨淋巴结识别成功14例,识别率为78%(14/18)。共有6例有淋巴结转移,淋巴结转移率为33%(6/18)。成功识别前哨淋巴结的14例中,淋巴结转移5例,其中前哨淋巴结和盆腔淋巴结均转移者2例,仅有前哨淋巴结转移者3例,准确性为100%,假阴性率为0。结论 宫颈癌根治术中淋巴显影和前哨淋巴结识别技术是可行的,但识别率尚有待提高。  相似文献

前哨淋巴结(sentinel lymph node,SLN)是原发恶性肿瘤淋巴转移的第一站,可以通过SLN中是否检测出肿瘤淋巴结转移,推测整个淋巴引流区域的肿瘤转移情况。目前有关SLN的研究已经应用到乳腺癌、黑色素瘤等恶性肿瘤的临床诊疗中。在妇科肿瘤方面,研究者最先在外阴癌中进行了SLN研究,之后在宫颈癌、子宫内膜癌中也相继开展了有关SLN检测及SLN活检(SLNB)的探索研究,并在临床上得到了一定的应用。本文结合相关文献,对国内外子宫内膜癌、宫颈癌、外阴癌和卵巢癌中SLN 的研究现状及目前尚待解决的问题进行简单总结。  相似文献

Lymph node status is the most important prognosticator of survival in women with early stage cervical cancer. Thus many patients with cervical cancer will undergo pelvic lymphadenectomy as part of the treatment. This procedure is associated with substantial morbidity. Use of the sentinel lymph node technique in women with cervical cancer has the potential to decrease this morbidity. Multiple studies have suggested that sentinel lymph node mapping in these patients is feasible, with excellent detection rates and sensitivity. This review examines the current body of literature about sentinel lymph node biopsy in women with cervical cancer.  相似文献

Study Objective

To demonstrate the feasibility of sentinel lymph node (SLN) biopsy using a laparoendoscopic single-site (LESS) approach in endometrial cancer (EC).

Design

A step-by-step video demonstration of the surgical procedure (Canadian Task Force Classification III).

Setting

The satisfaction of patients who undergo LESS hysterectomy is greater than that reported by patients who undergo multiport laparoscopic hysterectomy, owing to better cosmesis and reduced postoperative analgesic requirements [1]. SLN biopsy is associated with significantly lower estimated blood loss, shorter operation time, and less morbidity compared with systematic lymphadenectomy [2]. LESS surgery can be more feasible and safer with the use of SLN biopsy compared with complete lymphadenectomy in patients with early-stage EC.

Interventions

This 69-year-old woman with grade 2 endometrioid EC underwent SLN mapping followed by LESS SLN biopsy, total hysterectomy, and bilateral salpingo-oophorectomy. Before the umbilical incision was made, 1.25?mg/mL of indocyanine green was injected into the cervical stroma at the 3 o'clock and 9 o'clock positions to both deep and superficial levels. A 10-mm 30° standard-length optical camera for near-infrared fluorescence imaging was used. The total operative time was 75 minutes, and the estimated blood loss was 20?mL. SLNs were detected bilaterally between proximal parts of the external iliac arteries and veins. After SLN resection, total hysterectomy and bilateral salpingo-oophorectomy were performed. No postoperative complications occurred. The patient was discharged at 30 hours after surgery. In the final pathology, stage 1A G2 EC was detected.

Conclusion

LESS SLN biopsy and TLH-BSO is a feasible procedure and sentinel lymph node concept may increase the use of LESS in EC.  相似文献

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

OBJECTIVE: To describe our experience with the sentinel lymph node biopsy in cervical cancer patients, using a laparotomic approach and blue dye technique. METHODS: Between January 2003 and January 2005, patients with histologically proven FIGO stage IA2 to IIA carcinoma of the uterine cervix were submitted to SLN procedure if they were scheduled to have radical abdominal hysterectomy and pelvic lymphadenectomy. The SLN mapping was done after intracervical methylene blue (4 ml) injection. Final pathologic evaluation of SLNs included serial step sections and wide spectrum cytokeratin immunohistochemical analysis. RESULTS: Fifty patients were accrued to this prospective observational double-center study. A total of 86 SLNs (mean 1.9) were identified in the 45 patients with fruitful quest for SLN detection. The SLN detection rate per patient was 90%, and for the side of dissection, 72%. Bilateral SLNs were detected in 60% of cases. SLNs were identified in the external iliac and obturator areas in 55% and 38%, respectively; 5 isolated SLNs were discovered in the common iliac region. Ten patients (20%) had lymph node metastases; one of these had false-negative SLN. The false-negative rate and the negative predictive value, calculated by patient and by side of dissection, were 10% and 97.2%, and 8.3% and 98.4%, respectively. CONCLUSIONS: SLN detection with blue dye is a feasible procedure, particularly useful as a surgical staging procedure in young patients with small tumors. The true morbidity-sparing role of this technique in cervical cancer treatment is yet to be found.  相似文献
