Bone mineral density in women with breast cancer
Journal of Clinical Oncology, 2008
Introduction: Almost 1 in 8 women will have breast cancer during their lifetime. Several risk factors were identified; however, 70% of females with breast cancer have no risk factors. Many risk factors are associated with sex steroid hormones. Some studies have been focused on identification of the indices of cumulative exposures to estrogen during the patients' life. One of these indicators is bone mineral density (BMD). Our aim was the comparison of BMD in young patients with and without breast cancer, and finding a relationship between breast cancer and bone density. Methods: In this case-control study, 120 people were enrolled; 40 patients with breast cancer and 80 normal healthy persons as control group. Measurement of BMD was performed in both groups and compared. Results: Both groups were matched in age, weight, age at menarche, age at first marriage and first pregnancy, number of pregnancies over 32 weeks and lactation period, and taking supplemental calcium and vitamin D. However, there was a significant difference between the two groups in terms of estrogen intake, family history of breast cancer, and history of breast masses (P = 0.03, P = 0.03, P ≤ 0.01, respectively). A significant difference was found between BMD, bone mineral content (BMC), and t-scores of lumbar spine of the two groups; they were higher in the control group (P = 0.08, P ≤ 0.01, P = 0.06, respectively). Conclusion: This study shows that BMD of young patients with breast cancer is not higher than normal similar age females; thus, BMD is not directly a risk factor for breast cancer.
High Bone Mineral Density of the Lumbar Spine Is Positively Associated with Breast Cancer
BioMed Research International
Objective. The objective of this study was to verify possible associations between bone mineral density (BMD) and breast cancer in recently diagnosed women in the Brazilian Mid-west region, considering the menopausal status of patients. Methods. A case-control study was conducted with 142 cases of breast cancer and 234 controls matched by for age, body mass index (BMI), and menopausal status (pre- and postmenopause), performed in a university hospital in the Brazilian Mid-west. Lumbar spine (L1–L4), femoral neck, and total femur BMD were measured by the dual-energy X-ray absorptiometry (DXA) method. For association, a logistic regression analysis was used. Results. Women in the highest lumbar spine BMD quartile presented had a higher chance of developing breast cancer (OR = 2.31; 1.02–5.25; p = 0.045), after adjusting for the confounding variables. Nonetheless, there were no statistically significant differences in the association between pre- and postmenopause in that quartile and ...

Background: The primary objective of this study was to assess BMD change in Iranian females with breast cancer. Methods: A sample of 73 female breast cancer patients treated with adjuvant chemotherapy either alone or followed by radiotherapy between March 2013 and February 2016 were considered for this study. Bone mineral density (BMD) change was evaluated by measuring z-score of lumbar spine, femoral neck (right and left side) as well as biochemical measurements. With respect to WHO categorization for the treatment of osteoporosis, patients were categorized as normal BMD, osteopenic and all analysis was done separately. Results: In women with normal BMD, lumbar spine and femoral neck (right side) z-score decreased significantly by 15.7 and 39%, respectively (p<0.05). In osteoporosis group, there was no BMD change in any of the lumbar or femoral neck z-scores. However, in osteopenic patients, femoral neck BMD decreased significantly by 40.9% after 8 months (p=0.003). The level of all measured biomedical markers such as Ca, Alb, P and vitamin OHD decreased significantly in a follow-up visit in both osteoporosis and normal BMD. Conclusion: Our results revealed that adjuvant chemotherapy led to unfavorable effects on lumbar spine and femoral neck means z-score during 8 months. Also, unfavorable changes in biochemical markers appeared in all groups.
Bone mineral density in women newly diagnosed with breast cancer: a prospective cohort study
NPJ breast cancer, 2022
Estrogen may have opposing effects on health, namely increasing the risk of breast cancer and improving bone health by increasing bone mineral density (BMD). The objective of this study was to compare dual-energy X-ray absorptiometry (DXA) BMD between women newly diagnosed with breast cancer and matched controls without breast cancer. Women newly diagnosed with breast cancer treated between April 2012 and October 2017 were prospectively enrolled. A control group was established of women with negative mammography or breast ultrasound, matched 1:1 by age, body mass index, parity, and the use of hormone replacement therapy. All those included had DXA BMD, and lab assessments at enrollment. Of 869 women with newly diagnosed breast cancer, 464 signed informed consent. Of the 344 who completed the study protocol, 284 were matched to controls. Overall, the mean age was 58 years. Compared to the control group, for the breast cancer group, the mean vitamin D level was lower (48.9 ± 19.0 vs. 53.8 ± 28.8 nmol/L, p = 0.022); and mean values were higher of total hip BMD (0.95 ± 0.14 vs. 0.92 ± 0.12 g/cm 2 , p = 0.002), T score (−0.38 ± 1.17 vs. −0.68 ± 0.98, p = 0.002), and Z score (0.32 ± 1.09 vs. 0.01 ± 0.88, p < 0.001). Among the women with breast cancer, no correlations were found of baseline BMD with tumor size or grade, nodal involvement, or breast cancer stage. We concluded that women with newly diagnosed breast cancer tend to have higher BMD than women with similar characteristics but without breast cancer. This implies that BMD might be considered a biomarker for breast cancer risk.
Osteoporosis in women with breast cancer and its effect on quality of life: a pilot study
Journal of B.U.ON. : official journal of the Balkan Union of Oncology
The primary aim of this study was to evaluate the risk of osteoporosis (OP) in patients who had received adjuvant chemotherapy for breast cancer. The secondary aim was to investigate the effect of OP on the quality of life of these patients. Twenty-six patients with breast cancer and 21 healthy controls were recruited into the study. All breast cancer patients were treated with 6 cycles of adjuvant chemotherapy. Bone mineral density (BMD) was measured by Dual-energy X-ray absorptiometry (DXA). Short Form-36 (SF-36) questionnaire was used to assess the quality of life. The mean lumbar area BMD value was significantly lower in patients with breast cancer than in healthy controls (p=0.017). There were no significant differences in the femoral area BMD measurements between the groups. OP was more pronounced after 24 months of the last chemotherapy course than in the first 12 months (p=0.04). The most affected domain of the SF-36 in patients with breast cancer was the physical role. Adju...

Introdução: O uso de quimioterápicos para o tratamento de pacientes com câncer de mama tem aumentado a sobrevida dessa população. Entretanto, pode reduzir significativamente a densidade mineral óssea (DMO). Objetivo: Verificar a alteração da densidade mineral óssea em mulheres com câncer de mama submetidas a quimioterapia, assim como as características clínicas e os fatores de risco. Métodos: Revisão integrativa da literatura de artigos publicados no período de 2006 a 2016, realizada por meio de termos específicos nos bancos de dados da PubMed e da SciELO. Resultados: No período selecionado, foram identificados 898 artigos (897 na base PubMed e 1 na SciELO). Entre os seis artigos recuperados para leitura na íntegra, observou-se redução considerável na massa óssea na coluna lombar e no fêmur. Os principais tipos associados à redução foram os regimes doxorrubicina e ciclofosfamida (AC), ciclofosfamida, metotrexato e 5-fluorouracil (CMF) e ciclofosfamida, epirrubicina e 5-fluorouracil (FEC). Além disso, houve maior redução da DMO entre as mulheres com idade acima de 50 anos, caucasianas e que apresentaram falência ovariana precoce induzida pela quimioterapia. Conclusão: O uso de quimioterápicos para tratamento do câncer de mama pode acarretar perda de massa óssea, principalmente quando se utilizam os regimes AC, CMF e FEC em mulheres com idade acima de 50 anos e entre aquelas que apresentam menopausa precoce decorrente desse tratamento.

The present study aimed to evaluate the extent of loss in bone mineral density (BMD) during neoadjuvant and adjuvant chemotherapy for early stage breast cancer. A retrospective cohort study was conducted to quantify the loss of BMD one year following the start of chemotherapy and to identify potential risk factors of excessive BMD loss. Based on DXA-scans prior to and one year following chemotherapy, the loss of BMD was evaluated in early stage breast cancer patients treated from January 2012 to December 2014. A total of 492 patients received either eight cycles of neoadjuvant or six cycles of adjuvant chemotherapy. The final analysis included 152 patients with two DXA-scans. The patients had a significant loss of BMD in the hip [-0.0124 g/cm 2 (95% confidence interval (CI)-0.018;-0.007) P<0.001] and in the lumbar spine [-0.029 g/cm 2 (95% CI:-0.036;-0.023) P<0.001] corresponding to a change of-1, 3 and-2, 9%, respectively. Premenopausal women had a significant loss of BMD in the lumbar spine-0.045 g/cm 2 equivalent to-4.3%, which was significantly increased compared with postmenopausal women (P<0.001) in the univariate analysis, whereas only a trend persisted in the multivariate analysis (P= 0.60). There was no significant difference in BMD loss (lumbar spine P=0.176) between patients receiving adjuvant and neoadjuvant chemotherapy. In conclusion, neoadjuvant and adjuvant chemotherapy is associated with significant BMD loss in both hip and lumbar spine. Furthermore, the results of the present study indicate that premenopausal women have a pronounced BMD loss in the lumbar spine. Further studies investigating osteoporosis prophylaxis in premenopausal patients are warranted.
High bone-mass density as a marker for breast cancer in post-menopausal women
The Breast, 2001
S U M M A R Y. Bone mass has been proposed as a marker of cumulative exposure to oestrogen in women. We have studied the association between bone mass and breast cancer in postmenopausal women. In 126 cases of breast cancers and 126 controls, the bone mineral density (BMD) of the lumbar spine (L2-L4), femoral neck, trochanter and Ward's triangle was measured by dual-energy X-ray absorptiometry. All cases of cancer were confirmed by pathological reports. A questionnaire including information on reproductive history and other variables was collected. BMD was significantly higher among breast cancer patients than controls at all sites, except at the femoral neck where BMD was increased in the cancer group, but not significantly. After adjustment for potential confounding factors, the estimated relative risk of breast cancer in the highest quartile of BMD compared to the lowest quartile ranged from 2.5 to 4.8 for various sites of measurement.
