Abstract Objective To evaluate the effect of non-sentinel lymph node status on prognosis of Luminal B ??HER2 negative?? early breast cancer. Methods Luminal B ??HER2 negative?? early breast cancer with positive sentinel lymph node treated from January 2008 to December 2014 in Peking University First Hospital entered the retrospective study. The clinicopathological features and their relationship with non-sentinel lymph nodes status were analyzed statistically. The effect of non-sentinel lymph nodes status on prognosis of Luminal B ??HER2 negative?? early breast cancer with positive sentinel lymph nodes were also analyzed. Results In the group of 142 patients with positive sentinel lymph nodes ??SLN???? the average number of SLNs detected in each patient were 2.06±1.26. The number of positive SLNs was associated with the status of non-sentinel lymph nodes?? but not the age?? BMI?? menopause?? T stage?? histological grade?? lympho-vascular invasion. Non-SLN axillary lymph node non-metastasis occurred in 78 patients (54.9%), DFS 93%, OS 93.1%; non-SLN axillary lymph node metastasis occurred in 64 patients (45.1%), DFS 95.2%, OS 91.9%. Based on Log-rank (Mantel-Cox) test, There was no significant difference between two groups in DFS (χ2=0.011, P=0.918) and OS (χ2=0.348, P=0.555) . Conclusion The number of positive sentinel lymph nodes in Luminal B ??HER2 negative?? early breast cancer patients with sentinel lymph nodes metastasis were associated with the status of non-sentinel lymph nodes. There were no statistical differences betweennon-sentinel lymph nodes metastasis group and non-metastasis group in disease free survival and over-roll survival.

Addition of adjuvant tamoxifen to cyclophosphamide,methotrexate and 5-fluorouracil for premenopausal women with oestrogen receptor-positive breast cancer

OBJECTIVE: To study the value of adjuvant tamoxifen (TAM) in premenopausal women with oestrogen receptor (ER)-positive breast cancer who received adjuvant cyclophosphamide, methotrexate and 5-fluorouracil (CMF) polychemotherapy. METHODS: Four hundred and two premenopausal ER-positive breast cancer patients who received CMF chemotherapy between January 1990 and December 1999 were retrospectively studied. Disease-free survival (DFS) and overall survival (OS) were used to evaluate the clinical value of TAM therapy. The relationships between nodal status and TAM were also analysed. RESULTS: After a mean of 41 months of follow-up, 43 (13.7%) patients died of breast cancer and 68 (19.9%) patients suffered recurrence. There was a significant difference between TAM and non-TAM treatment groups for DFS (p=0.0058), but no significant difference for OS. For node-negative patients, there was no significant difference between the TAM and non-TAM treatment groups for either DFS or OS. For node-positive patients, the difference between TAM and non-TAM treatment groups was significant for both DFS and OS (p=0.0497 and p=0.0285, respectively). CONCLUSION: TAM resulted in additional benefit to premenopausal patients with node-positive ER-positive breast cancer who received the CMF polychemotherapy regimen.     

保留乳头乳晕复合体的乳腺癌改良根治术预后的相关因素分析

目的探究影响保留乳头乳晕复合体(NAC)的乳腺癌改良根治术(NSM)预后的相关因素。 方法回顾性分析2011年1月至2014年12月84例早期原发性乳腺癌并接受NAC的NSM患者临床病理资料。使用统计软件SPSS 20.0进行数据分析,采用K-M生存曲线评估术后无病生存(DFS)及总生存(OS),采用单因素分析和Cox多因素分析影响NSM术后患者DFS和OPS的影响因素。P<0.05差异有统计学意义。 结果术后局部复发8例,远处转移6例,术后5年DFS为83.3%,OS为91.7%。多因素分析显示,肿瘤最大径、肿瘤距乳头乳晕距离(TND)、腋窝淋巴结状态、组织学类型及Her-2阳性是影响DFS的独立危险因素(P<0.05);而腋窝淋巴结状态是影响术后OS的独立危险因素(P<0.05)。 结论肿瘤最大径、TND、腋窝淋巴结状态、组织学类型及Her-2阳性是DFS的独立危险因素,腋窝淋巴结状态是OS的独立危险因素;腋窝淋巴结情况同时影响患者术后DFS和OS,术前系统、精准地评估并妥善处理特殊腋窝淋巴结可提高乳腺癌患者预后。     

Effect of Prevailing Local Treatment Options of Breast Cancer on Survival Outside Controlled Clinical Trials: Experience of a Specialist Breast Unit in North India

Background This study aimed at analyzing different treatments of breast cancer (BC) prevalent in the region, their effect on patients’ survival, and discusses the most suitable method within available resources. Methods The study was set up at a tertiary care hospital in north India. We retrospectively reviewed data of 473 female BC patients who attended the departments of Surgical Oncology and Radiotherapy from January 1997 to December 1999. Patients with cTNM stage IV and inoperable stage III were included; those who defaulted or were lost to follow-up were excluded. Out of 473 patients, 372 were selected. The selected patients were divided into groups on the basis of place and type of local treatment they received: (1) local excision only, (2) standard breast conservation therapy (BCT), (3) total mastectomy (TM) + axillary lymph node dissection + radiotherapy (RT), and (4) modified radical mastectomy (MRM) + RT. Data regarding recurrence and survival were analyzed in December 2005. Minimum follow-up was 6 years. Results Overall recurrence rates were significantly higher in patients operated elsewhere (P <0.0001). Of 194 operated at our Breast Unit, 25 (14.6%) of 171 MRM patients and none of 23 BCT had recurrence. Of 178 patients operated elsewhere, 44 (100%), 6 (42.9%), 41 (41%), and 8 (40%) developed recurrence in groups 1, 2, 3, and 4 respectively. Overall survival was significantly better in patients with MRM at our unit versus TM outside (93.6% vs. 80%). Conclusions Several types of treatment from improper local excision alone, BCT, TM, to a carefully done MRM are prevalent here. Properly done, MRM yields significant local control with survival benefit and appears to remain the gold standard in management of our BC patients.     

Fluorouracil, doxorubicin, and cyclophosphamide followed by tamoxifen as adjuvant treatment for patients with stage IV breast cancer with no evidence of disease

We conducted a single-institution study to determine whether local therapy plus six cycles of chemotherapy with 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) followed by 5 years of tamoxifen is superior to local treatment alone in terms of disease-free survival (DFS) and overall survival (OS) in patients with stage IV breast cancer with no evidence of disease (stage IV-NED breast cancer). Patients with breast cancer were eligible if they had histologic proof of a locoregional or distant recurrence that had been curatively resected, irradiated, or both and had no other evidence of disease. Patients who had received prior anthracycline therapy were not eligible. All patients received six cycles of intravenous FAC, with cycles repeated every 3 weeks. After completion of chemotherapy, patients whose tumors had not previously demonstrated resistance to tamoxifen and had positive or unknown estrogen receptor status received tamoxifen 20 mg by mouth daily for 5 years. Patients in this study were compared with a historical control population (patients with stage IV-NED breast cancer who never received systemic therapy) as well as with the patients in two previously reported trials of chemotherapy for stage IV-NED disease. Forty-seven patients were registered, but only 45 were evaluable. There was a highly statistically significant difference ( p < 0.001) in OS and DFS among the four groups, with patients in our most recent study having the best OS and DFS at 3 years compared with the control group (84% vs. 55% and 66% vs. 11%, respectively). When patients in all four groups were analyzed together in search of prognostic factors, we found that patients whose primary tumors had negative axillary lymph nodes had a statistically significant improvement in OS and DFS ( p < 0.01) compared with patients with positive axillary lymph nodes. No survival differences were found between patients with positive and those with negative hormone receptor status. This study demonstrates a benefit in terms of OS and DFS for patients with stage IV-NED breast cancer who receive doxorubicin-based adjuvant chemotherapy. The benefit was greater on patients with node-negative primary tumors. In patients with stage IV-NED disease, doxorubicin-based chemotherapy should be considered standard treatment after adequate local control is achieved.     

Does Breast Conservation Therapy in Young Women with Breast Cancer Adversely Affect Local Disease Control and Survival Rate? The M. D. Anderson Cancer Center Experience

Abstract: Historically, it was thought that young women with breast cancer had a poor prognosis and a high local disease recurrence rate after breast-conservation therapy. To determine the effect of breast-conservation therapy, the outcomes of young women with breast cancer who were treated at a single institution were retrospectively reviewed.
Between 1978 and 1993, 219 women ≤35 years of age with breast cancer were treated at the University of Texas M. D. Anderson Cancer Center and met the following criteria: no evidence of distant metastasis at the time of diagnosis, no prior treatment, and no concurrent cancers. The variables analyzed included demographics, type of surgery, TNM stage, use of adjuvant therapy, locoregional disease recurrences, distant metastases, and vital status. The median length of follow-up among surviving patients was 7.9 years (range, 1–17 years). Univariate analyses were performed using the log-rank test. Multivariate analyses were performed using the Cox proportional hazards model.
Seventy-nine patients underwent breast-conservation therapy (BCT) and 140 patients underwent modified radical mastectomy (MRM). Locoregional disease recurrences were identified in 27 cases: 12 in the BCT group and 15 in the MRM group. When patients were matched stage for stage, the type of local treatment did not correlate with the loco-regional recurrence rate (p = 0.236) or the disease-specific survival rate (p = 0.915). The five-year disease-specific survival rate was 84.2%. In the multivariate analysis, only TNM stage correlated with locoregional recurrence rate (p = 0.019) and disease-specific survival rate (p = 0.002).
This study shows no significant difference in locoregional recurrence rates or disease-specific survival rates in young women with breast cancer treated with BCT versus MRM.     

Loco‐regional Control After Neo‐adjuvant Chemotherapy and Conservative Treatment for Locally Advanced Breast Cancer Patients

Breast‐conserving treatment (BCT) has been validated for breast cancer patients receiving adjuvant chemotherapy. Our objective was to evaluate the difference in loco‐regional recurrence (LRR) rates between BCT and mastectomy in patients receiving radiation therapy after neo‐adjuvant chemotherapy (NCT). A retrospective data base was used to identify all patients with breast cancer undergoing NCT from 2002 to 2007. Patients with initial metastatic disease were excluded from this analysis. LRR was compared between those undergoing BCT and mastectomy. Individual variables associated with LRR were evaluated. Two hundred eighty‐four patients were included, 111 (39%) underwent BCT and 173 (61%) mastectomy. Almost all patients (99%) in both groups received postoperative radiation. Pathologic complete response was seen in 37 patients, of which 28 underwent BCT (p < 0.001). Patients receiving mastectomy had more invasive lobular carcinoma (p = 0.007) and a higher American Joint Committee on Cancer (AJCC) stage (p < 0.001) at diagnosis than those with BCT. At a median follow‐up of 6.3 years, the loco‐regional control rate was 91% (95% CI: 86–94%). The 10‐year LRR rate was similar in the BCT group (9.2% [95% CI: 4.9–16.7%]) and in the mastectomy group (10.7% [95% CI: 5.9–15.2%]; p = 0.8). Ten‐year overall survival (OS) rates (63% [95% CI: 46–79%] in the BCT group; 60% [95% CI: 47–73%] in the mastectomy group, p = 0.8) were not statistically different between the two patient populations. Multivariate analysis showed that AJCC stage ≥ III (HR: 2.6; 95% CI: 1.2–5.8; p = 0.02), negative PR (HR: 6; 95% CI: 1.2–30.6, p = 0.03), and number of positive lymph nodes ≥3 (HR: 2.5; 95% CI: 1.1–5.9; p = 0.03) were independent predictors of LRR. Ten‐year OS was similar in the BCT and in the mastectomy group (p = 0.1). The rate of LRR was low and did not significantly differ between the BCT and the mastectomy group after NCT. Randomized trials assessing whether mastectomy can be safely omitted in selected breast cancer patients (nonstage III tumors or those which do not require adjuvant hormone suppression) which respond to NCT are required.     

Outcome of breast-conserving treatment for axillary lymph node metastasis from occult breast cancer with negative breast MRI

PurposeWe conducted this study to investigate the prognosis and failure pattern after breast-conserving treatment (BCT) in patients with occult breast cancer (OBC) with negative breast magnetic resonance imaging (MRI) (MRI-OBC).Materials and methodsSurvival rates and failure patterns in 66 patients who received axillary lymph node dissection (ALND) and BCT for MRI-OBC between 2001 and 2013 at seven hospitals were analyzed. OBC was defined as adenocarcinoma in the axillary lymph node (ALN) +/− supraclavicular (SCN) or internal mammary lymph node (IMN) with a negative breast MRI.ResultsFifty-four patients had only ALN metastasis (ALN only), and 12 patients had ALN metastasis along with SCN or IMN metastasis (ALN + SCN/IMN). Median follow-up was 82 months. The 5-year overall, disease-free, and breast cancer-free survival rates were 93.4%, 92.1%, and 96.8%, respectively. Nine patients experienced recurrence: breast (n = 4), regional lymph nodes (RLN, n = 1), distant metastases (DM, n = 2), breast/RLN (n = 1), and breast/RLN/DM (n = 1). Five-year disease-free survival was significantly higher in ALN only patients compared to ALN + SCN/IMN patients (96.1% vs. 75.0%; p = 0.02).ConclusionsPatients with MRI-OBC were successfully treated with BCT. There was a small risk of ipsilateral breast cancer recurrence. Failure patterns depended on the extent of initial disease.     

Survival outcomes in pregnancy associated breast cancer: a retrospective case control study

Pregnancy-associated breast cancer (PABC) has been defined as breast cancer diagnosed during pregnancy or within one year of delivery. It is believed that after adjusting for age and stage, the 5-year survival rates are the same in both pregnant and nonpregnant women. We conducted a retrospective case-control study among patients treated at our institution between 1990 and 2005 to compare the 5-year survival outcomes for PABC with women treated for breast cancer who were not pregnant. Overall survival (OS) and disease-free survival (DFS) were estimated by the Kaplan-Meier method, and log rank tests were used to assess the associations between OS, DFS and pregnancy status, HER-2 status, ER/PR status, and family history. The median age was 33 years (range 24-42) for both groups. Twenty-two (55%) patients with PABC were ER/PR receptor positive compared with 20 (50%) for the controls. Ninety percent of patients with PABC received chemotherapy compared with 87.5% in the nonpregnant group. 91.5% of patients with PABC had breast-conserving surgery and 8.5% had mastectomies compared with 86% and 14%, respectively, for the control group. The median OS was 4.9 years in the PABC group compared with 6 years for the controls (p = 0.02). The median DFS was 2.7 years for the PABC group compared with 5.1 years for the controls (p = 0.01). The most common site of relapse was bone for the PABC group (27%) and local recurrence (33%) for the controls. Univariate analysis revealed that OS and DFS were associated with pregnancy status, family history, ER/PR status, and stage. After adjusting for age and stage, PABC patients had higher risk of both death (p = 0.01) and recurrence (p = 0.02) compared with nonpregnant controls. Women with PABC had significantly shorter OS and DFS compared with nonpregnant age and stage-matched controls.
