乳管镜检查可直接观察乳腺导管系统内病变,是诊断病理性乳头溢液的理想方法之一。对于有占位性病变的导管需手术切除病变导管及所属区段乳腺组织,传统的手术定位采用体表定位结合溢液乳管内注射亚甲蓝的方法,但是定位往往不准确,导致手术切除范围过大。近年来,有报道经乳管镜在病变乳管内置定位针的方法,有助于术中准确地找到病灶。笔者通过两种定位方式的对照,评估乳管镜下置入定位针在乳管内肿瘤手术中的临床应用价值,现将结果报告如下。 相似文献

Whether measured by qualitative assessment of the parenchyma pattern or quantitatively by percent mammographic density, breast
density is consistently a strong and independent risk factor for breast cancer (BC). Density is also a relatively common risk
factor, and therefore an important contributor to BC risk at a population level. Including density (with other risk factors)
in risk prediction models improves predictive accuracy; however, better standardization and/or automation of density measures
will make the integration of breast density into risk assessment, and its application in tailored screening and primary prevention,
more feasible. High breast density reduces screening sensitivity and is associated with risk of interval BC in screening;
it is also associated with cancers that have poorer prognostic features. Non-randomized studies of adjunct ultrasound screening
in women with mammography-negative dense breasts have provided evidence on incremental detection of BC with adjunct ultrasound
and high false-positives but have not examined impact on clinical end-points, mortality, or balance of potential benefits
versus harms. 相似文献

乳腺癌保留乳房治疗10a疗效分析 总被引:8,自引:0,他引:8
目的:研究评价保乳治疗的效果,分析1985年—1995年111例在该院行保乳治疗患者的远期疗效。方法:111例临床Ⅰ期、Ⅱ期患者行保乳手术,术后行全乳放疗,局部缩野照射。用SAS软件分析患者年龄,肿瘤大小,组织学类型,切缘,淋巴结转移,术后放疗与复发的关系,分析切除组织量与复发率和美容效果的关系。结果:中位随访10 a,10 a复发率10 % ,转移率27 %,生存率81 %。年龄、组织学类型、淋巴结转移与复发无显著性关系(P >0.05)。肿瘤大小,切缘情况与复发有关(P <0.01)。术后未行放疗的复发率高,达75 %。60Co放疗复发率高于加速器(11 % vs 5 %)。单纯局部复发与转移无明显相关性(P >0.05)。行象限切除复发率不低于肿瘤扩大切除(P >0.05),但明显影响美容效果。结论:保乳治疗适合不同年龄、不同组织学类型的早期乳腺癌,在保证切缘阴性的前提下,扩大切除范围不提高疗效反而会影响美容效果。放疗技术的提高有助于减少复发。 相似文献

Lavage of the ductal systems of the breast provides fluid (DLF) containing hormones and products of hormone actions that may represent more accurately the composition of the breast than samples collected from blood or urine. The present study was undertaken to assess the presence of potential cancer biomarkers, their variation among individuals at high risk for breast cancer, and differences associated with menopause and tamoxifen treatment. Seventy seven tamoxifen-eligible subjects with a 5-year breast cancer risk estimate (Gail > 1.6%)(N = 53) or recently diagnosed breast cancer (N = 24) were offered tamoxifen therapy; those not accepting tamoxifen were under observation only. After six months, all subjects underwent ductal lavage (DL) in an unaffected breast. Estradiol (E2), estrone sulfate, androstenedione, dehydroepiandrosterone (DHEA), DHEA sulfate, progesterone, cathepsin D and epidermal growth factor (EGF) were measured in DLF by immunoassays. Data were expressed as the mass of analyte per mg of protein in DLF and normalized by natural log transformation. With the exception of DHEA, none of the analytes measured were significantly lower in postmenopausal women than in premenopausal women. The mean log(e) concentration difference in estradiol was 10.9%. Tamoxifen treatment for 6 months did not result in a significantly greater concentration of E2 or in any of the other analytes in DLF of pre- or postmenopausal women. The between-duct variance of the concentration of free steroids within the same breast averaged 51% less than that between subjects, and was similar to that of non-diffusible proteins. The maintenance of estradiol concentrations in the breast after menopause demonstrates the importance of local biosynthesis. The fact that DLF E2 does not reflect the high serum concentrations of E2 during tamoxifen treatment indicates that breast concentrations of estradiol may be under feedback control. Unlike studies of low risk populations, progesterone concentrations were not significantly less in postmenopausal than in premenopausal women. The similarity in variance of free steroids and protein analytes between ducts of a breast indicates little transfer of steroids between lobules. 相似文献

Purpose of Review
There is very little clinical trial data available to guide the management of uncommon breast cancers. This review draws on classic and recent retrospective data to synthesize a clearer understanding of the biology and behavior of these rare tumors.Recent Findings
Avoid disfiguring surgery in the pursuit of very wide margins for benign phyllodes tumors unless there are adverse histological features. Encapsulated papillary carcinoma is very good prognosis breast cancer; do not over treat. Metaplastic carcinoma is a basal type breast cancer that may be more responsive to “BRCA1-like” treatments. Complete excision of the capsule is curative for most implant-associated anaplastic large cell lymphomas. Aromatase inhibitors are still controversial for male breast cancer; tamoxifen is standard.Summary
Available data are useful for guiding the treatment of rare breast cancers, but it must be recognized that there is still a great deal to be learned about each of these entities.16.

Aims: The purpose of our study was to evaluate the diagnostic performance of breast magnetic resonance imaging (MRI) in the evaluation of contralateral breast in patients with diagnosed breast cancer. A secondary objective was to determine accuracy of breast MRI in diagnosing multi-focal and multicentric lesions in the ipsilateral breast. Materials and Methods: Using a non-probability convenience sampling technique, patients with histopathologically diagnosed breast cancer with MRI of breast performed to exclude additional lesions were included. MRI findings were correlated with histopathology. In addition, follow-up imaging with mammography and ultrasound was also assessed for establishing stability of negative findings and for the detected of benign lesions. Results: Out of 157 MRI breast conducted during the period of 2008 to 2013, 49 were performed for patients with diagnosed breast cancer. The sample comprised of all females with mean age 50.7±11.0 years. The patient follow-up imaging was available for a period of 2-5 years. The sensitivity, specificity, and positive and negative predictive values of MRI in the detection of multifocal/multicenteric lesions was 85.7%, 88.8%, 60% and 96.6% respectively and for the detection of lesions in the contralateral breast were 100%, 97%, 83.3% and 100% respectively. Conclusions: Our study highlights the diagnostic performance and the added value of MRI in the detection of multifocal /multicenteric and contralateral malignant lesions. In patients with diagnosed breast cancer having dense breast parenchyma and with infiltrating lobular carcinoma as the index lesion MRI is particularly useful with excellent negative predictive value in the exclusion of additional malignant foci in the ipsilateral and contralateral breasts. 相似文献

Breast density is an independent risk factor for breast cancer and significantly decreases the sensitivity of mammography. Assessing a woman’s risk of developing breast cancer is becoming increasingly important for establishing individual screening recommendations and preventive strategies. This article reviews the factors influencing mammographic density (MD), the available methods of MD assessment, and its effect on breast cancer. Finally, we discuss the supplemental screening methods for women with dense breast tissue. 相似文献

血管生成在乳腺非典型增生及癌变过程中的作用 总被引:22,自引:1,他引:22
为探讨乳腺非典型增生至癌变过程中血管生成的作用及其规律以及血管生成与非典型增生程度及癌变的关系,本研究应用免疫组化法,以FⅧ为标志物对86例良、恶性乳腺病变组织中的血管内皮细胞进行组化染色。分别以微机图像分析系统和人工计数对微血管内皮细胞面积(MEA)和微血管密度(MVD)进行定量分析。结果发现,中重度非典型增生及癌变组织中的血管生成量MEA和MVD均明显高于正常乳腺、单纯上皮增生和轻度非典型增生(P<0.05)。结论:乳腺非典型增生过程中已有血管生成并随非典型增生程度的增加而增多;乳腺增生组织中的血管生成可反映乳腺癌前病变的恶性倾向 相似文献
