The third generation of aromatase inhibitors (AI) play an important role in the adjuvant treatment of hormonal positive postmenopausal breast cancer. Compared with tamoxifen, either upfront or sequential using of Al can both significantly improve the outcome of breast cancer patients. However, there is a continuous debate of sequence or upfront usage of Al in clinical applications. With the publication result of BIG 1-98 clinical trial and interpretation of the data, we can further recognize and optimize the usage of Al in breast cancer treatment.

Purpose: To evaluate the efficacy and toxicity of Navelbine( NVB) and Epirubicin ( Epi -ADM) as the neoadjuvant chemotherapy in the treatment of locally advanced breast cancer. Methods: From September 2001 to February, 2003, 76 cases, LABC patients ( II b ~ HI b ) were treated with NE chemotherapy before operation. Neoadjuvant chemotherapy regimens containing vinorelbine( N), 25 mg/m (days 1 and 8) and epirubicin( E), 60 mg/m (days 1) were administered every 3 weeks for three cycles before local treatment. The response in the primary tumor and the regional lymph nodes and the chemotherapy toxicity were observed for each patient. Results: The response in the primary tumor: clinical objective response was 84. 2% (19.7% (15/76) CR and 64. 5% (49/76) PR) , 14. 5% (11/76) SD and 1.3% (1/76) PD. Pathological complete response was found in 11 cases( 14. 5%). 9 cases (28. 1%) who have positive FNA result in the regional lymph node before chemotherapy showed negative result in the surgery specimen. The most common toxicities are leukocytopenia, nausea/vomiting and alopecia. Leucopenia grade 3-4 was reported in 54. 2% of the patients but there were no chemotherapy related toxic deaths. Conclusions: The combination of Vinorelbine and Epirubicin is a very active and well-tolerated regimen as neoadjuvant chemotherapy for the LABC.

This study examined the value of volume rendering (VR) interpretation in assessing the growth of pulmonary nodular ground-glass opacity (nGGO). A total of 47 nGGOs (average size, 9.5 mm; range, 5.7-20.6 mm) were observed by CT scanning at different time under identical parameter settings. The growth of nGGO was analyzed by three radiologists by comparing the thin slice (TS) CT images of initial and repeat scans with side-by-side cine mode. One week later synchronized VR images of the two scans were compared by side-by-side cine mode to evaluate the nGGO growth. The nodule growth was rated on a 5-degree scale: notable growth, slight growth, dubious growth, stagnant growth, shrinkage. Growth standard was defined as: Density increase ≥ 30 HU and (or) diameter increase (by 20% in nodules ≥10 mm, 30% in nodules of 5-9 mm). Receiver operating characteristic (ROC) was performed. The results showed that 32 nGGOs met the growth criteria (29 nGGOs showed an increase in density; 1 nGGO showed an increase in diameter; 2 nGGOs showed an increase in both diameter and density). Area under ROC curve revealed that the performance with VR interpretation was better than that with TS interpretation (P<0.01, P<0.05 and P<0.05 for observers A, B and C respectively). Consistency between different observers was excellent with both VR interpretation (κ=0.89 for observers A&C, A&B, B&C) and TS interpretation (κ=0.71 for A&B, κ=0.68 for A&C, κ= 0.74 for B&C), but time spending was less with VR interpretation than with TS interpretation (P<0.0001, P<0.0001 and P<0.05 for observers A, B and C, respectively). It was concluded that VR is a useful technique for evaluating the growth of nGGO.

Objective To explore the value of preoperative spleen-liver volume ratio for predicting recurrence of primary liver cancer after hepatectomy.Methods Clinical data of 75 cases of hepatocellular carcinoma undergoing hepatectomy were analyzed retrospectively.According to the preoperative spleen-liver volume ratio,these patients were divided into 2 groups:those with spleen-liver volume ratio ＜ 0.8,and spleen-liver volume ratio≥0.8.Patients were followed-up until March 2014.Cox ratio risk pattern analysis was used for the recurrent correlative factors.Results Univariate analysis showed that preoperative AFPL3％ ≥ 10％,the maximum diameter of the tumor ＞ 5 cm,the number of tumor ＞ 3,spleen-liver volume ratio ≥0.8,vascular invasion,positive resection margin and hepatic or portal vein tumor thrombus were all risk factors of poor disease-free survival (P ＜ 0.05).Cox regression analysis revealed that spleen-liver volume ratio ≥0.8,AFP-L3％ ≥10％,the maximum diameter of the tumor ＞5 cm and hepatic or portal vein tumor thrombus were independent predictors of poor disease-free survival after hepatectomy for hepatocellular carcinoma(P ＜ 0.05).Conclusions Preoperative spleen-liver volume ratio ≥0.8 was an independent adverse predictor of poor disease-free survival.

Objectives To calculate the rate of pathological underestimation for core needle biopsy (CNB)- diagnosed intraductal papillary tumors, to analyze the clinical and imaging data of patients and to dis-cuss factors for underestimation. Methods A retrospective analysis of patients undergoing core needle biopsy and subsequent surgical excision was performed. 1359 female patients undergoing CNB from Jan. 2010 to Feb. 2013 in Comprehensive Breast Health Center of Ruijin hospital were analyzed. Clinical, radiological and histo-logical variables were assessed using the Chi-square test, Fisher’s exact test and a binary logistic regression model in order to predict pathological underestimation for tumors. Results There were 50 patients with CNB-di-agnosed intraductal papillary tumors. The overall underestimation rate was about 44%(22/50). CNB-diagnosed atypical papillary lesions (OR=15.164, 95% CI 1.49-170.443) and BI-RADS 5 by MRI (OR=26.766, 95% CI 2.409-297.440)were significantly related to underestimation in these patients. Conclusions Considering the high underestimation rate in CNB-diagnosed intraductal papillary tumors, routine surgical excision should be per-formed to avoid potential malignancy, especially for patients with high risk factors. MRI is helpful in these pa-tients to predict underestimation.

Breast conserving surgery and sentinel lymph node biopsy are widely used in early breast cancer treatment. Right now, the mode of local regional recurrence (LRR) has significantly changed and the rate of ipsilateral breast tumor recurrence and axillary lymph node recurrence are steadily increasing. Due to its relatively low incidence of LRR compared with distant metastasis, inconsistent of pre-recurrence treatment, difficulty in surgical treatment, and few prospective clinical studies, there are rising new challenges for clinical management of LRR patients. In this article, based on new theory of LRR, clinical diagnosis and treatment progress, and our own clinical practice experience for LRR breast cancer patients, we propose that we should make pathological diagnosis and do systemic evaluation for LRR disease, then considering it as a curable disease, and integrating local and systemic comprehensive treatment for LRR patients, thus to improve their disease outcome.

Breast cancer is a heterogenetic disease. Multi-gene assay profiling can classify breast cancer into several molecular subtypes, which is better to predict disease prognosis and treatment response. Two prospective clinical trials validated the prognosis predictive value of 21 gene recurrence score and MammaPrint in early breast cancer, than to decrease the prescription of adjuvant chemotherapy and avoid side effect of chemotherapy. New multi-gene assay profiling integrating clinic-pathological factors or reflecting disease development and metastasis can help us predict disease outcome better, thus to achieve individualized therapy in breast cancer.

Objective: To analyze the association between clinicopathological factors and clinical diagnosis, treatment and surgery of local regional recurrence (LRR) in breast cancer. Methods: A retrospective study was done to evaluate consecutive 7 823 breast cancer LRR cases between January 2009 and August 2018 at Comprehensive Breast Health Center, Ruijin Hospital, Shanghai Jiaotong University School of Medicine. A total of 108 LRR patients were enrolled: 35 cases (32.4%) with ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery, 40 cases (37.0%) of chest wall recurrence (CR), and 33 cases (30.6%) with regional lymph node recurrence (LNR). All patients were female, aged from 26 to 83 years with a mean of 49 years. Clinicopathological factor and its relationship with different sites of LRR and following surgical choice were analyzed by χ² test, rank-sum test and Logistic regression. Survival analysis were performed between different LRR patterns and whether undergoing second surgery. Kaplan-Meier survival curves and Log-rank tests demonstrated the distribution of overall survival. Results: Both univariate analysis and multivariate analysis found that axillary lymph nodes (ALN) status (OR=7.27, 95% CI: 1.30 to 40.53, P=0.042) and disease-free interval (OR=0.18, 95% CI: 0.06 to 0.60, P=0.013) were related to different site of LRR. Compared with patients with IBTR, LNR and CR patients had a higher rate of ALN metastasis and a shorter disease-free interval. A total of 36 LRR patients underwent following surgery. In univariate analysis, initial ALN surgery (χ²=16.705, P=0.001), pathological type (χ²=7.047, P=0.03), ALN status (χ²=10.812, P=0.002), disease-free interval (χ²=6.118, P=0.023) and LRR site(χ²=19.328, P=0.000) were associated with surgical treatment for LRR patients. Multivariate analysis demonstrated that only site of LRR was independently associated with surgery (OR=0.17, 95% CI: 0.05 to 0.65, P=0.024). The 5-year overall survival was 100% and 60.1% (P=0.018) for LRR patients treated with surgery or not. Furthermore, CR patients had significantly worse overall survival than LNR and IBTR patients, with 5-year overall survival 53.1%, 73.5%, and 100% respectively (P=0.021). Conclusions Initial lymph nodes metastasis and disease-free interval are associated with different site of LRR. LRR site significantly influenced following surgery choice after LRR, which are both related with overall survival after LRR.
