目的 分析顺义区三轮乳腺癌筛查中110例间期癌患者的临床及病理特征。方法 将顺义区历年乳腺癌发病个案信息与北京市妇幼保健网络信息系统中适龄女性乳腺癌筛查数据进行关联,查询乳腺间期癌患者。将间期癌患者与同时期在我院乳腺中心就诊的乳腺癌患者进行特征比较。结果与门诊收治的原发性乳腺癌相比,间期癌患者年龄偏小、超声肿物较小,差异均有统计学意义(P<0.05)。与病灶大小相近的门诊收治的乳腺癌患者相比,真正间期癌X线检查恶性钙化和浸润性导管癌的比例均较高,差异均有统计学意义(P<0.05)。间期癌患者在乳腺癌筛查中转诊X线检查比例很低(0.91%),而110例间期癌确诊时有103例接受了乳腺X线检查,其中53例(48.2%)存在恶性钙化表现。结论 乳腺癌筛查中,年龄偏小的女性更易发生间期癌。由于间期癌患者中接近50%在诊断时存在X线下恶性钙化表现,因而若在以超声检查为主的乳腺癌筛查过程中结合乳腺X线检查,或许可以避免部分间期癌的发生。 相似文献

目的探讨多病灶乳腺癌不同病灶临床病理特点的异同,以便更好地指导临床治疗。 方法回顾性分析2014年11月至2016年8月南京医科大学第一附属医院乳腺外科收治的41例多病灶乳腺癌患者的临床病理资料。分析多病灶乳腺癌不同病灶的常规病理、免疫组织化学检测结果及分子亚型的异同,并采用χ2检验比较多病灶乳腺癌与同期150例单病灶乳腺癌的病灶直径、组织学分级、淋巴结状态和脉管内癌栓状况。 结果41例多病灶乳腺癌患者中,有2处病灶者32例,3处病灶者8例,4处病灶者1例;病灶直径≤2 cm者18例,>2 cm者23例;不同病灶病理类型相同者33例(80%),不同者8例(20%);不同病灶组织学分级相同者38例(93%),不同者3例(7%);不同病灶免疫组织化学标志物ER、PR、HER-2、Ki67表达水平不同者分别为3例(7%)、6例(15%)、5例(12%)、3例(7%);分子亚型不同者5例(12%)。多病灶乳腺癌与单病灶乳腺癌患者相比,组织学分级3级、淋巴结转移及脉管内癌栓分布的差异均有统计学意义[51%(21/41)比32%(48/150), χ2=5.154 ,P=0.023;59%(24/41)比41%(61/150), χ2=4.163 ,P=0.041;29%(12/41)比8%(12/150), χ2=13.257,P<0.001],但病灶直径的差异无统计学意义[56%(23/41)比56%(84/150),χ2=0.001,P=0.991)]。 结论多病灶乳腺癌不同病灶可存在不同的临床病理结果,因此,不同病灶均应进行常规病理与免疫组织化学检测,以便完整提供患者病理信息,选择最佳治疗方案。多病灶乳腺癌更易发生淋巴结转移及脉管内癌栓,提示可能预后较差。 相似文献

BackgroundThe cost-effectiveness of the 70-gene signature (70-GS) (MammaPrint®) has earlier been estimated using retrospective validation data. Based on the prospective 5-year survival data of the microarRAy-prognoSTics-in-breast-cancER (RASTER) study, the aim here was to evaluate the cost-effectiveness reflecting the actual use in clinical practice, including reality-based compliance rates.MethodsCosts and outcomes (quality-adjusted-life-years (QALYs)) were calculated in node-negative (N?) patients included in the RASTER study (n = 427). Sensitivity and specificity of the 70-gene and Adjuvant! Online (AO) were based on 5-year distant-disease-free survival (DDFS). Subgroup analyses were performed for two groups for whom benefit of the 70-gene had earlier been reported: (1) ductal, oestrogen receptor-positive (ER+), tumour diameter 10–30 mm, grade II, age 40–70; (2) ductal, oestrogen receptor-positive, tumour diameter 5–30 mm, grade II/III and age 40–70.ResultsBased on 5-year survival data, the cost-effectiveness of the 70-gene signature versus AO was prospectively confirmed. The total health care costs per patient were €26,786 for the 70-gene and €29,187 for AO. The quality adjusted life years yielded 12.49 and 11.88, respectively. The subgroups retrieved slightly higher life gains and higher costs, but all resulted finally in a favourable position for the 70-gene signature.ConclusionsThe use of the 70-gene signature, as judged appropriate by doctors and patients and supported by a low risk 70-gene signature as an oncological safe choice, was also found to be cost-effective. 相似文献

BACKGROUND: The tendency for breast cancer to form multiple lesions is important to consider when planning breast-conserving surgery. However, many unknowns remain regarding the pathology and prognosis of multiple breast cancer, and therefore it is clinically significant to investigate its clinicopathological properties. METHODS: Over the past 25 years, in the period between April 1972 and March 1997, we investigated the clinicopathological findings including the 5-year and 10-year survival rates of 66 patients treated for unilateral multiple breast cancer. RESULTS: Of the total of 1,334 female patients with unilateral breast cancer who underwent curative surgery at our hospital, we identified 66 (5.0%) patients with unilateral multiple cancer. The incidence of such cancer has been higher in recent years. Of the 66 patients, 50 (75.8%) were premenopausal, and the remaining patients were postmenopausal, but multiple cancer among postmenopausal women is a recent phenomenon. The ER positivity rate of the main lesion in patients with multiple breast cancer was 69.2% and that of PgR was 50.0%. The 5-and 10-year overall survival rate in all 66 patients with multiple breast cancer was 90.8% and 79.7%, respectively. CONCLUSION: In the past, multiple breast cancer was frequently identified in premenopausal women. However, the current findings indicate that its incidence among postmenopausal women has increased in recent years. In addition, prognoses were comparable for patients with multiple or solitary breast cancer, a relevant finding in the planning of breast-conserving surgery. 相似文献

Objective:To study the clinicopathological characters of triple negative breast cancer (TNBC).Methods:A total of 629 patients with breast cancer were reviewed, who were treated from 2003 to 2007 in Chongqing Cancer Institute. The comparison of clinicopathological features including TNM classification, histological type, tumor location, axillary lymphonodes status and neoadjuvant chemotherapy between TNBC and nontriple negative breast cancer (NTNBC) was performed. The overall response was evaluated by whether the patients achieve complete remission (CR) and partial remission (PR) after chemotherapy. Results:There were 69 TNBCs in the 629 patients with breast cancer. The premenopausal patients, which was found in 49/69 of TNBCs, was more than NTNBCs. The average diameter of tumor in TNBC group was 4.1 em, lager than NTNBC group. TNBC with axillary nodes metastasis occurred in 21 cases, and the axillary nodes metastasis rate was lower than NTNBC. The positive expression rate of p53 in TNBC was 44.9%, and the overall response (CR+PR) was 72.2%. No statistical differences were found regarding the positive expression rate of p53 and the overall response between TNBC and NTNBC. Conclusion:TNBC were a group of primary breast cancers with triple negative, tending to occur in premenopausal women, with larger tumors, lower axillary nodes metastasis rate. TNBC had worse clinical prognosis and currently lacked effective targeted therapies. 相似文献

There is an urgent need to understand distant metastases in breast cancer as they are the most lethal form of recurrence and
a major cause of mortality in patients. Some predictors for distant metastases, including nodal status, tumor grade, and hormonal
status, are useful in identifying patients at increased risk for distant metastases. Adjuvant endocrine therapy has been the
treatment of choice for postmenopausal women with hormone-sensitive breast cancer, and some therapies have shown significant
reductions in the risk of distant metastases. Skeletal metastases in breast cancer are treated with bisphosphonates with a
certain level of success. With more new agents undergoing clinical trials, a thorough review of the specific and long-term
safety of these agents is essential, as is a better understanding of the deterioration in the quality of life and cost concerns
of patients who develop distant metastases. Gene-expression profiling is a new entrant in the field of distant metastases
diagnosis, which is largely successful in defining gene signatures that predict the development of distant metastases. This
review will discuss the biology and the impact of distant metastases on outcomes for patients with breast cancer; it also
encompasses the current status, emerging focus, and future perspectives in treatment of skeletal metastases in patients with
breast cancer. 相似文献

PurposeIn Dutch guidelines, gene expression profiles (GEP) are indicated in estrogen receptor positive early breast cancer patients in whom benefit of chemotherapy (CT) is uncertain based on traditional prognostic factors alone. Aim of the present study is to assess the use and impact of GEP on administration of adjuvant CT in breast cancer patients who have according to national guidelines a clear indication to either use or withhold adjuvant chemotherapy (clinical high or low risk).MethodsClinical low- and high-risk patients, according to Dutch breast cancer guidelines, diagnosed between 2011 and 2014 were selected from the Netherlands Cancer Registry. Influence of GEP use and GEP test result on CT administration was assessed with logistic regression.ResultsOverall, 26,425 patients were identified; 4.8% of patients with clinical low risk (444/9354), 7.5% of the patients with a clinical high risk (1281/17,071) received a GEP. GEP use was associated with significantly increased odds of CT administration in clinical low-risk patients (OR = 2.12 95% CI: 1.44–3.11). In clinical high-risk patients, GEP use was associated with a decreased frequency of CT administration (OR = 0.55, 95% CI: 0.48–0.63). Adherence to the GEP result was higher in clinical high-risk patients with a discordant GEP result as compared to clinical low-risk patients with a discordant GEP result: 71.7% vs. 52.2%, respectively.ConclusionGEP is frequently used outside the indicated area and significantly influenced the administration of adjuvant CT, although adherence to the test result was limited. 相似文献
