妇科肿瘤前哨淋巴结研究现状   总被引:1,自引:0,他引:1  
前哨淋巴结 (SLN)是指最先接受肿瘤引流的第一站区域淋巴结。这组淋巴结多靠近肿瘤原发部位 ,且位于淋巴直接引流通道上 ,因此常常是最有可能发生转移的淋巴结。 1 974年Cabanas在阴茎癌的研究中提出了 SLN概念 ,之后逐渐引起了肿瘤外科界的重视。目前 ,SL N的研究几乎涉及到了所有实体肿瘤。在某些肿瘤 ,特别是乳腺癌的研究方面取得了突出的成果 ,已经认识到 SLN能够准确地反映乳腺癌区域淋巴结状况 ,对于 SLN阴性的病例可以采用较为局限的前哨淋巴结活检(SLNB)取代传统的区域淋巴结清扫术。在妇科领域 ,Leven-back于 1 984年最早…  相似文献

在我们身体内部,淋巴和血管、神经一起围绕连接着各个重要器官,淋巴系统起着过滤以及防御功能,它是由淋巴管道、淋巴组织和淋巴器官所组成的。淋巴瘤是一组起源于淋巴结或其他淋巴组织的恶性疾病,常发生于淋巴结和/或结外淋巴组织。相对于肺癌、肝癌、胃癌等各种常见的恶性肿瘤,淋巴瘤显得更抽象、知晓率更低。  相似文献

乳腺癌前哨淋巴结活检(Sentinel lymph node biopsy,SLNB)是乳腺外科领域在20世纪90年代中的一个里程碑.淋巴转移是乳腺癌重要的转移方式,前哨淋巴结(sentinel lymph node,SLN)是淋巴转移必经的第一站淋巴结.以SLNB评价腋窝淋巴转移的情况为乳腺癌的手术提供了全新的思路.通过这种微创方法可以筛查出腋窝淋巴结无转移的患者,避免不必要的腋窝清扫,保证了患者的美观和上肢功能.SLNB的活检方法主要有蓝染技术、淋巴放射显影技术、蓝染与淋巴放射显影结合技术.  相似文献

乳腺癌前哨淋巴结(sentinel lymph node,SLN)是最早接受肿瘤区内淋巴引流和发生肿瘤转移的第一站淋巴结。若该淋巴结无转移,则其他淋巴结出现转移几率小,估计仅为5%以下或更低。通过SLN活检预测腋窝淋巴结是否转移,可避免无转移腋窝淋巴  相似文献

BACKGROUND: Clinical records of 24 Japanese patients suffering from a primary malignant skin tumor were summarized, and the efficacy of lymphatic mapping (LM) and sentinel lymph node biopsy (SLNB) in cases with possible lymphatic metastasis was investigated, and compared with previous reports. METHODS: There were 17 cases of malignant melanoma (MM), 4 of squamous cell carcinoma (SCC), 2 of extramammary Paget's disease, and 1 of eccrine porocarcinoma. LM and SLNB were performed as additional treatment during extended surgery. RESULTS: Blue-stained lymph ducts and nodes were observed in 21 of 24 cases (87.5% identification rate). In these 21 cases, 3 sentinel lymph nodes (SLNs) were identified in 1 patient (4.8%), 2 SLNs in 5 patients (23.8%), and one SLN in 15 patients (71.4%). In MM, distant metastasis was seen in 3 of 10 cases (30%) with negative SLN. In these 3 cases, Breslow's thickness of the tumor ranged from 2.0 to 3.9 mm (average 2.6 mm). Except for MM, no distant metastases were observed in 7 cases with negative SLN. CONCLUSION: The incidence of MM in Japanese is about 0.001%, and the accumulation of reliable data is slow. Although MM is rare, SCC is more common. Therefore we investigated the clinical data of non-MM patients at risk of metastasis. SLN biopsy in non-MM patients was shown to be linked with their prognosis. In conclusion, the SLN biopsy technique is useful in the early stages of MM, and for non-MM patients at risk of lymphatic metastasis.  相似文献

Regional lymph node status is the most important prognostic factor in breast cancer. Sentinel lymph node biopsy is the standard method of axillary staging in early breast cancer patients with clinically negative nodes. Preoperative lymphoscintigraphy might support refining biopsy findings by determining the number and location of sentinel lymph nodes. In aged or overweight patients, in the presence of atypical or extra-axillary lymphatic drainage, non-visualized lymph nodes, or sentinel lymph nodes close to the isotope injection site, detection could be aided by a new, hybrid imaging tool: the single-photon emission computed tomography combined with computed tomography (3D SPECT/CT). For the first time in Hungarian language, authors overview the literature: all 14 English-language articles on the implementation of 3D SPECT/CT in sentinel lymph node detection in breast cancer are included. It is concluded that 3D SPECT/CT increases the success rate and quality of preoperative sentinel node identification, and is capable of providing a more accurate staging of breast cancer patients in routine clinical practice.  相似文献

The historical perspective of the sentinel lymph node concept   总被引:1,自引:0,他引:1  
The sentinel lymph node procedure is currently standard care in the treatment of breast cancer. The introduction of this procedure in 1992 would not have been possible without the pioneering discoveries regarding lymph nodes and cancer. The Italian surgeon Gaspar Asellius (1581-1626) visualized the lymphatic vessels of a dog after it had been fed and shortly before dissection. At the end of the 17th century, the French anatomists Lauth and Sappey visualized the lymphatics by injecting deceased criminals with mercury. In 1858, the German pathologist Virchow (1821-1902) launched the theory that lymph nodes act as defensive barriers. He also made the first microscopical illustration ofa sentinel lymph node. Gould et al. and Caba?s independently launched the precursors of the current modern sentinel lymph node concept in 1959 and 1977 respectively. Gould et al. were the first people to use the term "sentinel node'. Caba?as used lymphangiography for the visualisation of the sentinel lymph node. Controversies about the barrier function of the lymph nodes, the fear of skip metastasis and the difficulties of performing the Caba?as procedure, prevented a breakthrough of this concept. In 1992 Morton et al. rediscovered the valuable sentinel node biopsy concept and introduced blue dye for the investigation of patients with melanoma. The combination of lymphoscintigraphy, intra-operative gamma probe guidance and patent blue further increased the reliability of the sentinel lymph node biopsy procedure. Unnecessary lymph gland dissection procedures with considerable morbidity can be prevented by this procedure.  相似文献

With sufficient experience, sentinel node biopsy has a high identification rate for several techniques in the case of colorectal cancer. However, the sensitivity of the procedure seems to be too low to justify the replacement of routine pathological examination of the whole mesentery by sentinel node biopsy. Unexpected lymphatic drainage patterns can be found in about 5% of the patients. Therefore, the role of sentinel node biopsy in determining the extension of the resection is minimal in the case of colorectal cancer. In contrast, sentinel node biopsy is helpful in identifying the lymph nodes with the highest risk of harbouring metastases and it facilitates the scrutinising of the lymph node by the pathologist. This will lead to more micrometastases being detected. The prognostic significance of micrometastases and the impact on survival of adjuvant systemic therapy in such patients should be investigated in randomised controlled trials. At present, sentinel node biopsy in colorectal cancer should be restricted to a research setting.  相似文献

In the treatment of malignant tumors regional lymphadenectomy is used for two purposes. It is used partly for staging the regional lymph nodes which is a significant and independent prognostic factor and determines the need for adjuvant oncologic treatment and partly for achieving locoregional disease control. Removal of tumor-free lymph nodes by regional lymph node clearance is unnecessary according to our current knowledge. Since the sensitivity and specificity of non-invasive clinical examinations are insufficient in predicting the nodal status the histological study of the regional lymph nodes cannot be abandoned. A new and minimally invasive surgical procedure, the mapping and removal of the first tumor draining lymph node, the sentinel node provides the possibility of pathological nodal staging without performing formal lymphadenectomy. Mapping of the sentinel node can be performed by the use of a radioisotope and intraoperative hand-held gamma-probe or a vital blue dye or a combination of these two. This latter method was used by the authors in 73 patients (25 with malignant melanoma and 48 with breast cancer). Sentinel lymph node biopsy was performed successfully in 92% of patients with melanoma and 90% of patients with breast cancer. In three breast cancer patients the sentinel node inaccurately predicted the axillary status as negative, but is was in 93% accurate in predicting the histologic nodal state. According to our preliminary experiences intraoperative gamma-probe guided sentinel lymph node biopsy is considered a feasible procedure in both malignant melanoma and breast cancer. More experiences are needed before introducing this method in the routine clinical practice.  相似文献

OBJECTIVE: To determine the reliability of a peroperative frozen section examinations of sentinel lymph nodes in mammary carcinoma. DESIGN: Retrospective. METHOD: In the Reinier de Graaf Hospital and Diagnostic Centre SSDZ Delft, the Netherlands, the results of frozen section from sentinel lymph node investigations of mammary carcinomas from 1997-2000 were compared with the final pathological results. If axillary dissection had been performed on these patients, the histopathological findings of the dissected lymph nodes were also studied. RESULTS: Frozen sections were made of 287 sentinel lymph nodes from 275 patients. A tumour was found in the sentinel lymph nodes of 64 patients and these patients immediately underwent a complete axillary lymph node dissection. For 31 of these patients a tumour was also found in the other lymph nodes. In 29 of these 31 patients, histological examination had shown extranodal extension. The frozen sections from the sentinel nodes of the remaining 211 patients were considered negative. However, in 13 of these patients, the paraffin sections of the sentinel node nevertheless showed a tumour and the remaining axillary lymph nodes were removed in a second operation. In the last 89 patients studied, the sentinel lymph nodes were cut at four levels and stained immunohistochemically at one level for cytokeratins. Accordingly micrometastases were found in the sentinel lymph nodes of 4 of the 13 patients with (false-)negative frozen sections. False-positive results did not occur. CONCLUSION: The major advantage of the sentinel node method in breast cancer is that for women without metastasis present in the sentinel node, axillary dissection is avoided. By means of a peroperative examination of frozen sections, 83% of the patients with a metastasis in the sentinel lymph node (or about one quarter of all patients) were spared from having a second operation for axillary dissection at a later stage.  相似文献

OBJECTIVE: To determine in patients with mammary carcinoma and a sentinel node metastasis whether pathological parameters of the sentinel node metastasis and the primary tumour might have predictive value with respect to the presence of metastases in other axillary nodes. DESIGN: Prospective. METHOD: The study group consisted of the first 100 consecutive patients with a sentinel node metastasis, who subsequently underwent a complete axillary dissection. The patients with metastases in the non-sentinel nodes were compared to those without such metastases regarding the size of the largest sentinel node metastasis and the presence of extranodal tissue invasion near any such node, and size, and type of the primary tumour. RESULTS: The median size of the metastases in the sentinel lymph node in the two groups was 3 mm versus 13 mm respectively (p < 0.001) and the frequency of extranodal tissue invasion 3% versus 74% respectively (p < 0.001); the combination of these factors strongly predicted the presence of non-sentinel lymph node metastases in the axilla (94% area under the receiver operating characteristics curve). None of the 30 patients with a micrometastasis < or = 2.0 mm in the sentinel lymph node had metastases in the non-sentinel axillary lymph nodes. Metastases were present in the non-sentinel axillary lymph nodes in 29 of the 31 patients with extranodal tissue invasion near the sentinel node. CONCLUSION: In breast cancer patients with a sentinel lymph node metastasis < or = 2.0 mm and without extranodal tumour growth a complete axillary lymph node dissection might be unnecessary as the risk of additional metastases was very small.  相似文献

Abstract:
Objective To evaluate the clinical significance of the axillary conservative surgery by sentinel lymph node biopsy (SLNB) using preoperative lymphoscintigraph technique with 99mTc-SC and methylene blue in early-stage breast cancer patients. Methods The sentinel lymph node (SLN) of 187 patients were located with preoperative lymphoscintigraph technique with 99mTc-SC and labeled with methylene blue during the operations. The metastasis of SLN was detected using frozen section technique. There were 51 patients whose SLN were positive having been carried with modified radical mastectomy of breast cancer and axillary lymph node dissection (ALND), 136 patients' SLN were negative,58 patients of those were carried with mammectomy or partial mastcctomy and ALND (group A),while 78 patients were carried out with mammectomy or partial mastectomy only (group B). The sentinel lymph nodes were detected with HE stain after surgery. All the patients were treated with chemotherapy,and the patients with partial mastcctomy must be treated with radiotherapy. There were 2 patients with micrometastasis in group B being treated with mammectomy or partial mastcctomy only,and carried out with ALND again. Results The number of cases with upper limb numbness, edema, dysfunction in group A were 36,8 and 45 cases, in group B were 2,0,0 case respectively. Group A compared with group B was increased significantly (P< 0.05). The number of local recurrence within 1, 3 and 5 years were 0,0,2 cases;lymphatic metastasis were 1,5,8 cases; the distant metastasis were 2,8,12 cases; the disease-free survival were 60,57,49 cases. In group B, the number of local recurrence within 1, 3 and 5 years were 0,0,6 cases, lymphatic metastasis were 3,8,12cases,the distant metastasis were 4,8,16 cases,the disease-free survival were 76,70,61 cases. There were not significant differences between the two groups(P> 0.05). Conclusion It is simple and accurate to carry out SLNB using preoperative lymphoscintigraph technique with 99mTc-SC combined with methylene blue,and the effect is reliable.  相似文献
