Although locoregional recurrence (LRR) after mastectomy is regarded as a signal of disease progression,but it is different from distant metastasis.Some patients could have better prognosis and benefit from salvage treatments,especially for patients with isolated LRR.Time to recurrence,site of recurrence and number of recurrent nodules have great influence on the prognosis of patients with LRR.For suited patients with LRR,surgical resection and endocrine therapy are valuable in suitable cases,but the role of chemotherapy still need further study.

Objective To investigate the efficacy of TTC and FTC regimens as neoadjuvant chemotherapy in breast cancer. Methods Collecting clinical data of 325 patients received neoadjuvant chemotherapy with TIC and FTC regimens from June 2004 to April 2008, among them 138 patients received neoadjuvant chemotherapy with TTC regimen in one group, and 187 patients received neoadjuvant chemotherapy with CTF regimen in the other group. The expression of Topo Ⅱ a in specimen of 325 patients before neoadjuvant chemotherapy were detected by immunohistochemical method. Results Among the 325 cases of neoadjuvant chemotherapy, the overall response rate (RR) was 87.7 % in TIC arm and 67.4 % in FTC arm (P=0.000), but in the group of Topo Ⅱ a(+) Her-2(-), the overall response rate (RR) was 87.8 % in TTC arm and 79.4 % in FTC arm (P=0.266), and in the groups of Topo Ⅱ a(-), there was statistical significance; the pathologic complete response rate (pCR) was 13.7 % in TIC ann and 11.2 % in CTF ann (P=0.491). Conclusion TIC regimen is superior to FTC regimen in the response rate of neoadjuvant chemotherapy, but patients with negative expression of Topo Ⅱ a may get more benefits from 9eoadjuvant taxane and anthracycline chemotherapy.

Objective To evaluate the diagnostic value of breast mass-like lesions by digital breast tomosynthesis technique (DBT) versus full field digital mammography (FFDM).Methods 182 breast mass cases undergoing respectively DBT and FFDM diagnosis were reviewed to evaluate the the sensitivity,specificity and accuracy,breast BI-RADS classification and differences of edge character.Results Of the 182 cases,101 cases were malignant,81 cases were benign.DBT and FFDM in malignant mass detection rate were 95.0％ and 95.0％ respectively,the benign tumor detection rate were 80.2％ and 80.2％ respectively,the difference was statistically significant (P ＜ 0.05).The diagnostic sensitivity was 93.1％ (94/101) and 82.2％ (83/101),specificity was 66.7％ (54/81) and 53.1％ (43/81),accuracy was 81.3％ (148/182) and 69.2％ (126/182),all the differences were statistically significant (P ＜ 0.05).The BI-RADS classification difference of the malignant mass was statistically significant (x2 =12.912,P =0.044 5),and the benign mass was also statistically significant (x2 =12.739,P =0.026 0).The clear edge benign tumors detected by DBT and FFDM respectively were 65 and 45 cases (x2 =10.224,P =0.001 4).The spicule sign detected by DBT and FFDM respectively in malignant tumors were 71 and 50 cases (x2 =8.244,P =0.004 1).Conclusion DBT compared to traditional FFDM photography improves the lesion visibility,increases the diagnostic sensitivity and specificity,conducing to the identification of benign and malignant lesions.

Objective To discuss the protein level of hypoxia-inducible factor 1-alpha(HIF-1α),glucose transporter-1 (Glut-1)and vascular endothelial growth factor(VEGF) in breast cancer tissue in diabetic patients and its significance.Methods HIF-1α,Glut-1 and VEGF protein levels were measured by immunohistochemical staining in 112 cases of primary breast cancer tissues.CD31 labeled vascular endothelial cells were used to evaluate micro vascular density (MVD).The correlation between the effect of blood sugar control and clinicopathological parameters was analyzed.Results The expression of HIF-1α,Glut-1 and VEGF protein in breast cancer tissues of diabetic patients was significantly higher than that in breast cancer tissues of non-diabetic patients(t =2.255,P =0.030; t =2.154,P=0.038; t =2.225,P =0.032).HIF-1α was positively correlated with Glut-1 and VEGF in diabetic patients with breast cancer (r =0.561,P =0.003 ; r =0.435,P =0.014).The level of MVD in breast cancer tissues of diabetic patients was obviously higher than that in the non-diabetic patients with breast cancer(t =9.458,P =0.000).The effect of blood sugar control was significantly correlated with lymph node metastasis and tumor stage in diabetic patients with breast cancer(x2 =4.689,P =0.030; x2 =5.051,P =0.025).Conclusion Hypoxia-related factors including HIF-1α,Glut-1 and VEGF and MVD are upregulated in diabetic patients with breast cancer,and the effect of blood sugar control is correlated with lymph node metastasis and tumor stage,suggesting diabetes mellitus may promote tumor progression through high glucose and hypoxia in breast cancer.

Objective To explore the diagnostic value of digital breast tomosynthesis technique (DBT) in breast suspicious calcified lesions.Methods Clinical data of 135 patients using DBT and FFDM (Full field digital mammography) was respectively analyzed.Results Of the 135 cases,43 cases were malignant,and 92 cases were benign.The diagnostic sensitivity DBT and FFDM were 93.0％ (40/43)and 88.4％ (38/43),specificity were 88.0％ (81/92) and 75.0％ (69/92),accuracy were 89.6％ (121/135) and 79.3％ (107/135),the differences were statistically significant (P ＜0.05).The ROC curve area (AUC) of DBT and FFDM were 0.905 ± 0.026 and 0.817 ± 0.034 (P =0.000 2).In premenopausal,postmenopausal and breast density ACR3-4 cases,DBT accuracy is higher than FFDM (P ＜ 0.05).The BI-RADS classification difference of the benign calcified lesions was statistically significant (x2 =11.740,P =0.038 5).Conclusions Compared with the traditional FFDM,DBT has a higher value in the diagnosis of breast suspicious calcified lesions,especially for benign calcified lesions.

Objective To evaluate the efficacy and safety of etoposide capsule on metastatic breast cancer. Methods Forty-five advanced breast cancer patients treated with oral etoposide during Feb.1,2012 and Oct.31, 2016 in our department were enrolled in our study,with their general data,median number of treatment lines, treatment effect,common adverse reaction collected.

Objective To evaluate the safety and efficacy of therapeutic ERCP for patients above 90 years of age.Methods The data of 37 patients of above 90 years who underwent 42 ERCP procedures from January 2001 to December 2009 were studied retrospectively and compared with those of 152 matched patients ( 168 procedures) below 65 years old at a 1∶4 ratio for success rate and complications.Results The rate of complete success,partial success,and failure in observation group was 73.81％ (31/42),19.05％(8/42) and 2.38％ (1/42),respectively,which were similar (P ＞0.05) with those in control group,with complete success rate at 85.12％ ( 143/168),partial success rate at 12.50％ (21/168) and failure rate at 2.38％ (4/168).The rate of terminated operation in observation group (4.76％,2/42) was significantly higher than that of the control group (0.00％,0,P =0.039).The overall rate of complication in observation group was 7.14％ ( 3/42 ),slightly higher than that of the control group ( 6.55％,11/168,P ＞0.05 ).There was no significant difference between the two groups regarding the rates and severity of such complications as pancreatitis,hemorrhage and infection ( P ＞ 0.05 ).No perforation or death was observed.Conclusion Therapeutic ERCP for patients of 90 years or older is safe and effective.Adverse events related to chronic concomitant diseases need early detection and proper management.

OBJECTIVETo investigate the predictive factors affecting sentinel lymph node status in early breast cancer patients.

METHODSClinicopathological data of 1 038 patients with early breast cancer, who underwent sentinel lymph node biopsy in Henan Tumor Hospital between July 2010 and August 2013, were reviewed. Logistic regression analysis was performed to identify the relevance of clinicopathological features with sentinel lymph node metastases.

RESULTSThis group was consisted of 1 038 female patients with an average of 48.6 years. Positive sentinel lymph nodes were found in 22.9% (238/1 038) of the patients. The average number of sentinel lymph nodes removed by surgery was 3.8. Tumor size, tumor location, histopathology, ER/PR status and Ki-67 level were significantly correlated with SLN metastasis(P < 0.05 for all). All the above factors but Ki-67 level were significant independent predictors for SLN metastasis(P < 0.01 for all).

CONCLUSIONNegative hormone receptor status, invasive cancer of non-specific histopathological type, tumor size >2 cm, and tumor location in the outer upper quadrat are independent predictive factors of sentinel lymph node metastasis in patients with early breast cancer.
