Objective To summarize the recent studies on diagnosis and treatment for pregnancy-associated breast cancer (PABC) to provide evidence for diagnosis and treatment for PABC. Methods By PubMed, Medline, and CNKI retrieval system, with “pregnancy-associated breast cancer or PABC, diagnosis of pregnancy-associated breast cancer or PABC, treatment of pregnancy-associated breast cancer or PABC” as key words to retrieval for the recent researches about PABC. All of the publications about studies on diagnosis and treatment for PABC were reviewed and summarized. Results Diagnosis of PABC included ultrasound, mammography, magnetic resonance imaging, needle biopsy, and so on, and the treatment contained surgery, chemotherapy, endocrine therapy, radiation therapy, and targeted therapy. However, when diagnosis and treatment for PABC involved, the impact to patients with pregnancy and fetus must be considered in priority. Conclusions By reviewing the studies of relevant papers about diagnosis and treatment for PABC which can provide a clinical guidance for clinicians. Usage of bevacizumab and lapatinib still needs to further be studied.
The overexpression of C-erb B-2 oncogene in breast cancer was examined in 245 cases with immunohistochemical techniques.The results showed that:①Significant associations of C-erb B-2 overexpression with high histological grade (P<0.05), positive axillary node status (P<0.05), advanced clinical stage (P<0.05) and the absence of hormone receptor(P<0.05) were identified in breast cancer.②Overexpression of C-erb B-2 oncogene was related with 5-year and 10-year survival rate, and considered as a prognostic factor for breast cancer independent of axillary node status. Detection of C-erb B-2 oncogene overexpression could be arranged as a regular pathological examination in breast cancer.Combined with axillary node and estrogen receptor, progestin receptor status, the results can be used in determining the prognosis and planing the treatment programme in breast cancer.
Objective To explore the expressions of androgen (AR) and Stathmin in triple negative breast cancer (TNBC) and analyze the correlation between these expressions and clinicopathologic features. Methods Eighty-three patients who were diagnosed as TNBC and met the inclusion criteria from 2005 to 2009 in the Sichuan Provincial People’s Hospital were collected retrospectively. The expressions of AR and Stathmin in the TNBC tissues by using the method of EnVision immunohistochemistry. The correlation between AR or Stathmin expression and age, tumor size, lymph node status, or histological grade was analyzed by Spearman test. Results The AR and Stathmin positive expression rates in the patients with TNBC were 37.3% (31/83) and 98.8% (82/83), respectively. The AR expression was positively correlated with age(rs=0.302, P=0.006)and pathological grade (rs=0.225, P=0.041), but was not correlated with tumor size or lymph node status. The Stathmin expression was not correlated with age, tumor size, lymph node status, or pathological grade (P>0.05) . Conclusions The AR expression is correlated with the age or pathological grade but Stathmin expression was all not correlated with the clinicopathologic features. AR or Stathmin as a prognosis indicator in patients with TNBC are needed to more research.
Objective To investigate expression of p16 protein in breast cancer and its clinical significance. Methods Using immunohistochemical techniques (LSAB) the expression of p16 protein in 107 breast carcinomas was examined. Results The positive rate of p16 protein expression was 40.19% (43/107). The p16 protein over expression of the cases surviving ≤5 years and surviving ≥10 years were 8.00% and 75.68% respectively. Conclusion Expression of p16 protein might play an important role in the prognosis of breast cancer.
Objective To explore the correlation between homocysteine (Hcy) level and the risk of breast cancer,and try to find a new method to reduce the risk factors and benefit for treatment of breast cancer. Methods From January2010 to December 2012, 245 cases of breast cancer (breast cancer group), 109 cases of benign breast tumor (benign breast tumor group), and 78 cases of healthy women (healthy control group) in the Sichuan Provincial People’s Hospital, who were in accordance with the inclusion criteria, were analyzed retrospectively. The difference of Hcy level was compared among three groups. Meanwhile the relation between Hcy level and patients’s age, blood glucose, serum creatinine, estrogen receptor (ER), progesterone receptor (PR), Ki-67 (%), tumor diameter, or axillary lymph node status was analyzed.Results ① The Hcy level was significantly different among the breast cancer group, benign breast tumor group, and healthy control group (P<0.001). The Hcy level of the breast cancer group was significantly higher than those of the benignbreast tumor group (P<0.001) or healthy control group (P<0.001), but the Hcy level was not significantly different bet-ween the benign breast tumor group and healthy control group (P=0.082) . ② The Hcy levels of different types of the breastcancer (type of Luminal A, Luminal B, Her-2, and triple negative) were significantly higher than those of the benign breast tumor group (except for Her-2 type, P<0.05) or healthy control group (P<0.05). ③Plasma Hcy level of the patients with benign and malignant breast tumor was positively correlated with age (r=0.197, P=0.004) or serum creatinine level (r=0.381, P<0.001), but not correlated with blood glucose (r=0.023, P=0.668). ④Plasma Hcy level of the patients with malignant breast tumor was positively correlated with age (r=0.267, P=0.007) or serum creatinine level (r=0.341, P<0.001), but not correlated with blood glucose (r=-0.005, P=0.935), tumor diameter (r=-0.049, P=0.443), axillary lymph node status (r=-0.006, P=0.921), or Ki-67 (%) (rs=-0.029, P=0.650). Conclusions Plasma Hcy level of breast cancer patient is abnormally elevated, and it may have some relation with the occurrence of breast cancer.
