目前第三代芳香化酶抑制剂(Aromatase Inhibitors,AIs)已广泛应用于早期及转移性乳腺癌的辅助治疗。为绝经后激素受体阳性乳腺癌患者的治疗提供了新的一条途径。然而,由于AIs抑制绝经后乳腺癌患者体内雄激素转变为雌激素过程中芳香化酶的活性导致体内雌激素水平降低,而雌激素对骨组织具有保护作用,因此服用芳香化酶抑制剂的患者将会出现骨丢失。 相似文献

目的探讨阿仑膦酸钠预防来曲唑引起的绝经后早期乳腺癌患者骨量丢失的疗效。方法选择服用来曲唑的绝经后乳腺癌患者82例,随机分为2组。A组42例服用来曲唑,B组40例服用来曲唑的同时给予阿仑膦酸钠治疗。分别在服用来曲唑前及服药后6、12个月采用双能X线骨密度仪对82例绝经后乳腺癌患者进行骨密度(BMD)检测。结果 2组患者接受来曲唑治疗后6、12个月,BMD均出现下降;来曲唑治疗后12个月,A组较B组BMD下降更明显(P均<0.05)。结论来曲唑可加剧绝经后乳腺癌患者骨量丢失;应用阿仑膦酸钠可有效减轻患者的骨量丢失。 相似文献

Purpose
A growing body of evidence indicates that zoledronic acid (ZA) can improve the clinical outcome in patients with breast cancer and low estrogen levels. In the present study, we aimed to investigate the survival benefit of ZA administration in postmenopausal Korean women with breast cancer who were also receiving aromatase inhibitors.Methods
Between January 2004 and December 2010, 235 postmenopausal breast cancer patients undergoing aromatase inhibitor therapy were investigated. All patients were postmenopausal, as confirmed by laboratory tests. Of these patients, 77 received adjuvant upfront ZA for at least 1 year in addition to conventional adjuvant treatment. The remaining 158 patients never received ZA and were treated according to the St. Gallen guidelines.Results
The baseline characteristics for ZA treatment were not different between the two groups. The median follow-up time was 62 months, and the patients who received ZA in addition to aromatase inhibitors showed a better recurrence-free survival compared to those who received aromatase inhibitors alone (p=0.035). On multivariate analysis, the patients who received ZA showed a better recurrence-free survival independent of the tumor size, nodal status, progesterone receptor, and histological grade. For this model, Harrell c index was 0.743. The hazard ratio of ZA use for recurrence-free survival was 0.12 (95% confidence interval, 0.01-0.99).Conclusion
Our findings suggest that upfront use of ZA as part of adjuvant treatment can offer a survival benefit to postmenopausal breast cancer patients receiving aromatase inhibitor treatment. 相似文献12.

Introduction/BackgroundThe purpose of this study was to describe modification of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) distributions in breast cancer patients after aromatase inhibitor (AI) therapy using computed tomography (CT) volumetric measurement of abdominal body fat distribution.Patients and MethodsSixty-four consecutive patients who were receiving adjuvant AI therapy were included in this study. Patients were evaluated using CT before and after at least 6 months of AI therapy with imaging follow-up of 4.3 ± 2.2 years. Abdominal fat distribution was automatically calculated using a workstation that obtained total abdominal adipose tissue (TAAT) area (mm3). SAT was manually segmented and VAT was determined as TAAT − SAT. Percentages were calculated for change of TAAT, VAT, and SAT. VAT/SAT ratio was calculated.ResultsPercentage of TAAT after AI therapy was increased by a mean of 9.1% from baseline (16,280.3 ± 6953.3 mm3) to (17,763.6 ± 6850.8 mm3). Two groups of patients were observed; those with an increase in TAAT and those with a decrease. Modification of VAT/SAT ratio was observed (from 1.38 to 1.69) in all subjects, reflecting a relative increased volume of VAT (mean, 18%) and slight mean reduction of SAT (mean 1.9%).ConclusionIn our study, therapy with AI in breast cancer patients was accompanied with a change in fat distribution to relatively greater VAT/SAT ratio in patients, regardless of whether they gained or lost weight after therapy. Because this pattern of fat distribution is associated with metabolic disorders, attention must be paid to these clinical manifestations in patients during their follow-up management. 相似文献
