All patients had lymph node-negative breast cancer and were postmenopausal at the time of diagnosis.
所有患者在确诊时均有淋巴结阴性乳腺癌以及处在绝经期。
Conclusions: MMP-2 is an unfavorable prognostic factor in lymph node-negative breast carcinoma patients and it is an important prognostic factor.
结论：MMP - 2蛋白在淋巴结阴性乳腺癌转移复发中起着重要作用，是重要的预后因子。
Because the low false negative rate of SLN biopsy, the technique allows axillary lymph node dissection (ALND) avoided if the SLN is negative.
因为腋窝前哨淋巴结活检的假阴性率低，故对前哨淋巴结阴性的病人可以不做进一步腋窝淋巴结清扫。
Of those surgically stage, 10 patients (76.9%) were lymph node positive and 3 patients (23.1%) were node negative.
术后病理提示10例患者（ 76 9% ）腋淋巴结阳性，3例淋巴结阴性。
No one had positive pelvic lymph node and negative SLN, The predictive rate was 100% and the false -negative rate was zero.
未发现SLN无转移而盆腔其余淋巴结存在转移者，SLN对盆腔淋巴转移的预测准确性为100%，假阴性率为0。
Objective To study the prognostic identification of lymph node negative breast carcinoma by quantitative pathologic technique.
目的探讨定量病理技术对腋淋巴结阴性乳腺癌预后判断的应用价值。
The number of lymph nodes resected is a significant prognostic factor for patients with colorectal cancer, especially for those node-negative patients.
术中切除的淋巴结数目与结直肠癌患者的预后密切相关，特别是对无淋巴结转移的患者具有重要的临床意义。
Methods The expression of CK20 and CEA were detected in 647 lymph nodes histologically node-negative in 118 patients after radical operation of colorectal carcinoma.
方法118例大肠癌根治术后647枚淋巴结常规检查阴性的标本进行CK20和CEA的检测。
Metastatic rate of lymph node in neck central area was the highest (46.8%), but micrometastasis of lymph node couldn't be found with CT leading to false negative in 5 cases with PTC.
颈中央区淋巴结转移率最高(46.8%)，并且小的转移淋巴结ct不能发现而出现5例假阴性。
Conclusion Prophylactic lymph node dissection can potentially prolong the survival time of the patients with node negative colorectal cancer.
结论对无显微镜下淋巴结转移的结直肠癌患者，尽量切除全数淋巴结可明显延长患者的存活时间。
The expression level of CXCR3 in the lymph node-positive group was higher than that in the lymph node-negative group ( P < 0. 05 ).
乳腺癌组织中淋巴结转移阳性组CXCR3的表达率明显高于淋巴结转移阴性组（P＜0.05）；
The expression level of CXCR3 in the lymph node-positive group was higher than that in the lymph node-negative group ( P < 0. 05 ).
乳腺癌组织中淋巴结转移阳性组CXCR3的表达率明显高于淋巴结转移阴性组（P＜0.05）；
