Abstract:
Objective To investigate the safety and clinical prognosis of breast conserving operation in treat-ment of triple negative breast cancer.Methods 157 patients with breast cancer were divided into the non triple nega-tive breast cancer group (n=76) and triple negative breast cancer (n=81) according to its receptor expression,clin-ical pathological features, local recurrence after 5 years.Distant metastasis and survival situation were compared between two groups.Results The age<35 years patients of triple negative group accounted 17.3%,significantly higher than 7.9%of the non triple negative group(χ2 =5.331,P<0.05);the size of tumor≥5cm of triple negative group accounted 79.0%,significantly higher than 59.2% of the non triple negative group(χ2 =7.022,P<0.05);The patients with positive family history and lymph nodes of the triple negative group were 9.9%and 28.4%,signifi-cantly higher than 2.6%and 17.1%of non triple negative group,the difference between the two groups was statisti-cally significant (χ2 =6.283,4.865,all P<0.05);The local recurrence,distant metastasis rate and 5 year survival rates between the two group were not significantly different(χ2 =2.559,2.829,2.361,all P>0.05);The 5 year dis-ease free survival rate of the triple negative group was 80.25%,significantly lower than 94.74%of the non triple neg-ative group (χ2 =6.572,P<0.05).Conclusion The patients with triple negative breast cancer is younger,their tumor size is large and has a high proportion of family history.Their recurrence rate,distant metastasis rate and 5 year overall survival rate are as better as the patients with non triple negative breast cancer after breast preservation opera-tion,which has high security and good clinical application value.
