The ACOSOG Z0011 (Z11) trial demonstrated the presence of a group of breast cancer patients with some residual axillary disease who did not benefit from axillary lymph node dissection (ALND) in the presence of whole breast radiotherapy and systemic therapy at short term follow-up. It is important that further long-term follow-up of this cohort continues. The outcomes of those patients fitting Z11 criteria who do not undergo ALND should be recorded on a prospective register to ensure close observation should any late divergence in overall survival develop. It is also essential that future studies are inclusive of groups excluded from Z11 rather than simply a re-hash of the trial. 相似文献

ObjectivesTo use data from the BreastSurgANZ Quality Audit (BQA) to examine the patterns of completion axillary lymph node dissection (cALND) after sentinel lymph node (SLN) biopsy in women treated for early breast cancer in Australia and New Zealand and to compare it to the Australian and New Zealand guidelines in cases of both positive and negative SLN results.Materials and methodsPatients were sub grouped as having primary tumours ≤3 cm and >3 cm and further analysed according to year of surgery, SLN status and final nodal status where cALND was recorded. Multivariate analysis was performed examining tumour size, grade, presence of lymphovascular invasion (LVI), HER2 and oestrogen receptor status, patient age and number of positive sentinel nodes as predictors for subsequent axillary surgery.Results14879 patients were identified from 2006 to 2010. 79.8% of patients with a positive SLN result underwent cALND. Age >70 years and a greater number of involved SLN predicted no cALND among SLN positive patients. 10.3% of patients who had a negative SLN result underwent cALND. Younger age, higher grade, lymphovascular invasion and tumour size >3 cm predicted cALND among SLN negative patients.ConclusionsAccording to the BQA from 2006 to 2010 the Australian and New Zealand guideline recommendations for SLN positive patients to have cALND and SLN negative patients not to have cALND were adhered to in 79.8% and 89.7% of cases respectively. 相似文献

Background
The therapeutic significance of intramammary lymph nodes is uncertain. The purpose of this study was to identify the appropriate surgical management of the axilla in intramammary node-positive patients undergoing sentinel lymph node (SLN) biopsy.Methods
A retrospective review of consecutive patients staged between September 1996 and December 2004 was performed. Intramammary node identification and pathologic findings were compared with the status of axilla.Results
Among 7,140 patients, intramammary nodes were identified in 151 (2%). Positive intramammary nodes were identified in 36 patients (24%). Axillary disease was identified in 61% of intramammary node-positive patients. No additional axillary disease was identified when axillary lymph node dissection was performed in intramammary node-positive patients with negative axillary SLN biopsy results.Conclusions
The results suggest that completion axillary lymph node dissection may be based on the status of axillary SLN biopsies in clinically node negative patients when intramammary lymph node metastases are identified in the breast specimens. 相似文献8.

Sentinel lymph node biopsy (SLNB) is a standard in diagnostic and therapeutic management of patients with nonadvanced invasive breast cancer. The aim of this paper was to evaluate the clinical importance of the failure of sentinel lymph node (SLN) identification during SLNB performed to spare axillary lymph nodes. A total of 5396 patients with invasive breast cancer qualified for SLNB, treated in a period from Jan 2004 to June 2018. All cases of the failure of SLN identification and reasons underlying this situation were analyzed retrospectively. In 196 (3.6%) patients, SLN was not identified (group I), and this resulted in a simultaneous axillary lymph node dissection. 48.5% patients from this group were diagnosed with cancer metastases to lymph nodes (vs 23.6% patients with SLN removed—group II, P < .00001)—stage pN1 in 44.2% of the cases, stage pN2 in 22.1% of the cases, and pN3 in 33.7% (in group II—73.4%, 19.5% and 7.1%, respectively), with a presence of extracapsular infiltration in 68.4% patients (vs 41.7% in group II) and with a significantly higher percentage of micrometastatic nature in group II (17.0%, vs 3.2% in group I). The failure of intraoperative sentinel lymph node mapping indicates a significantly increased risk of breast cancer metastases to the axillary lymph system. At the same time, it can also indicate higher cancer stage and its increased aggressiveness. For this reason, in such situation performance of axillary lymph node dissection still appears to be the approach most advantageous for patients. 相似文献

胃癌单个淋巴结转移规律及临床意义 总被引:1,自引:0,他引:1
目的分析胃癌淋巴结转移的规律以指导临床规范化治疗。方法对天津医科大学附属肿瘤医院1999年7月至2004年6月间经手术治疗、清扫淋巴结数大于或等于10枚、术后病理证实仅有1枚淋巴结转移的胃癌患者临床资料进行回顾性分析.并对淋巴结跳跃与非跳跃转移、横向与非横向转移患者的资料进行对比。结果全组65例患者共检出淋巴结1415枚.平均21.8枚/例;单个淋巴结转移率的分布从多到少依次为N0.3(30.8%)、No.4(21.5%)、No.6(15.4%)、No.7和No.8(均为6.2%)、No.1和No.2及N0.5(均为4.6%)、No.12(3.1%)和No.14及No.16(均为1.5%);其中跳跃转移20.0%(13/65),横向转移42.2%(19/45)。单因素分析显示.淋巴结跳跃性转移仅与肿瘤大小有关(X2=4.447,P=0.035):淋巴结横向转移与各临床病理因素均无关。但淋巴结跳跃与非跳跃转移、横向与非横向转移间患者的生存曲线差异有统计学意义(P=0.000.P=0.000)。结论胃癌淋巴结转移规律总体遵循由远及近的转移顺序.但跳跃转移和横向转移方式也占有一定比例.对于胃癌淋巴结跳跃转移和横向转移的高危患者.术中应加强相应区域淋巴结清扫以提高患者生存率。 相似文献

PURPOSE: Modified radical inguinal lymphadenectomy for carcinoma of the penis is presented that satisfies the requirement for complete groin dissection, while significantly decreasing postoperative complications. MATERIALS AND METHODS: Eight patients with squamous cell carcinoma and 2 with leiomyosarcoma of the penis underwent bilateral modified inguinal lymphadenectomy, including removal of the superficial and deep inguinal lymph nodes. To avoid damage to the vessels of the groin region that run parallel to the inguinal ligament and lie in the fat of the superficial layer of the superficial fascia dissection is done beneath this layer. The proper cleavage plane is just above the membranous layer of the superficial fascia, beneath which the superficial inguinal lymph nodes are located. The saphenous vein is preserved and the sartorius muscle is left in situ, so as not to disturb collateral lymphatic drainage. RESULTS: At a followup of 6 to 104 months no skin necrosis, infection or deep venous thrombosis occurred. In 2 patients early moderate lymphedema of the lower extremities resolved with time, 2 had scrotal edema and 3 had a transient lymphocele. CONCLUSIONS: As described, modified radical inguinal lymphadenectomy decreases the morbidity associated with groin dissection, while removing superficial and deep inguinal lymph nodes. 相似文献

目的探讨乳腺癌分子分型是否影响腋窝淋巴结的术式选择。方法检索有关乳腺癌分子分型与腋窝淋巴结转移情况的文献并进行综述。结果三阴型乳腺癌患者的前哨淋巴结与非前哨淋巴结阳性率均较低,luminalB型和HER-2过表达型患者的腋窝淋巴结转移率较高,尤其是luminalB型乳腺癌患者,其前哨淋巴结阳性率、非前哨淋巴结阳性率均较其他分子分型高,对于行保乳手术的老年患者,当仅有1~2枚前哨淋巴结转移时,可免行腋窝淋巴结清扫;对于肿瘤体积较大的年轻患者,即使前哨淋巴结阴性,非前哨淋巴结阳性的可能性仍然较大,行腋窝淋巴结清扫可能会使这部分患者受益。结论对于腋窝淋巴结的术式选择,乳腺癌分子分型也是需要考虑的因素之一。 相似文献

PURPOSE: We determined the primary pathological features of clear cell renal cell carcinoma that are predictive of positive regional lymph nodes at radical nephrectomy (RN) and developed a protocol for the selective use of extended lymph node dissection. MATERIALS AND METHODS: We studied 1,652 patients who underwent RN for unilateral pM0 sporadic clear cell renal cell carcinoma between 1970 and 2000. A multivariate logistic regression model was used to determine the pathological features of the primary tumor that were associated with positive regional lymph nodes at RN. RESULTS: There were 887 (54%) patients with no positive nodes (pN0), 57 (3%) with 1 positive node (pN1), 11 (1%) with 2 or more positive nodes (pN2) and 697 (42%) who did not have any lymph nodes dissected (pNx). Nuclear grade 3 or 4 (p <0.001), presence of a sarcomatoid component (p <0.001), tumor size 10 cm or greater (p = 0.005), tumor stage pT3 or pT4 (p = 0.017) and histological tumor necrosis (p = 0.051) were significantly associated with positive regional lymph nodes in a multivariate setting. These features can be used to identify candidates for extended lymph node dissection at the time of RN. For example, only 6 (0.6%) of the 1,031 patients with 0 or 1 of these features had positive lymph nodes at RN compared with 62 (10%) of the 621 patients with at least 2 of these features. CONCLUSIONS: The primary tumor pathological features of nuclear grade, sarcomatoid component, tumor size, stage and presence of tumor necrosis can be used to predict patients at the greatest risk for regional lymph node involvement at RN. 相似文献
