ABSTRACT
Objective To evaluate the effects between video endoscopic inguinal lymphadenectomy (VEIL ) and open inguinal lymphadenectomy(OIL) to provide the evidence-based basis for the selection of the clinical therapy schemes .Methods The related clinical controlled trial literature on the effective comparison of VEIL and OIL were retrieved from the databases of PubMed ,Co-chrane library ,Elsevier ,CNKI and Wanfang database .The screening was independently performed by 2 reviewers according to the including and excluding criteria .The related data were extracted and performed the meta analysis by the RevMan 5 .2 software .Re-sults A total of 4 trials were included .There were 146 cases of inguinal lymphadenectomies ,in which 61 cases were VEIL and 85 cases were OIL .The meta-analysis results showed that there were no statistical differences between the two operation modes in terms of the operative time(WMD=32 .33 ,95% CI -25 .70-90 .36 ,P=0 .27) ,intraoperative blood loss(WMD=9 .10 ,95% CI -76 .03-94 .23 ,P=0 .83) ,number of removed lymph nodes(WMD=0 .77 ,95% CI -1 .66-3 .20 ,P=0 .53) ,number of positive re-moved lymph nodes(WMD=0 .08 ,95% CI -0 .23-0 .40 ,P=0 .61) ,postoperative drainage time(WMD= -1 .30 ,95% CI -6 .40 -3 .80 ,P=0 .62) ,postoperative hospital stay (WMD= -4 .02 ,95% CI -10 .19-2 .15 ,P=0 .20) ,but the difference between VEIL and OIL in term of surgical complications had statistical significance (OR=0 .08 ,95% CI 0 .03-0 .26 ,P<0 .01) .Conclusion VEIL has equivalent efficacy to OIL ,but has less surgical complications .
ABSTRACT
Objective:This study aimed to investigate the clinical significance of hormone receptor status detection in simultane-ous axillary metastasis for hormone receptor-negative primary breast cancer patients. Methods:Using immunohistochemical methods, hormone receptor status detection in axillary lymph node metastasis was performed among breast cancer patients with simultaneous ax-illary metastasis in the First Affiliated Hospital of Chongqing Medical University. The subjects comprised patients who visited the clin-ic for follow up or those who were hospitalized from July 2012 to January 2013. Endocrine therapy was given for patients diagnosed with positive hormone receptor in their simultaneous axillary metastasis. Results:Out of 56 patients with hormone receptor-negative primary breast cancer, 14.3%gained estrogen receptor (ER), 3.6%gained progesterone receptor (PR), and 5.4%gained ER and PR in their simultaneous axillary metastasis, and then underwent endocrine therapy. The discordance rate of hormone receptor expression be-tween primary tumor and axillary metastasis was 23.3%. Conclusion:Some discordance rates of hormone receptor status between pri-mary tumor and simultaneous axillary metastasis were observed. Through hormone receptor status detection in simultaneous axillary metastasis, we may possibly distinguish patients with negative ER and PR, among whom endocrine therapy may be active.
