LONG-TERM SURVIVAL EFFECTS OF PREOPERATIVE BREAST MRI IN PATIENTS WITH BREAST-CONSERVING SURGERY.

The benefit of breast magnetic resonance imaging (MRI) in breast-conserving surgery (BCS) is unclear. Our study compared breast cancer patients with and without preoperative breast MRI and their long-term oncologic outcomes are reported. A total of 1378 BCS cases with early breast cancer between 1996 and 2017 were reviewed. Patients with carcinoma in situ or neoadjuvant treatment or having breast MRI after tumor excision were excluded. Of 1378 patients, 270 (19.5%) had preoperative MRI. There were no significant differences regarding T and N stage and molecular subtypes between the groups. Surgical margins were significantly wider in the breast MRI group. Five-year overall survival (OS) was 96.9% in the MRI group and 94.3% in the control group, and this difference was not significant (p=0.11). Five-year local-regional recurrence-free survival (LRFS) was not significantly different either (98.8% and 96.5%, respectively, p=0.41). When analyses were repeated only for patients with hormone receptor-negative or triple-negative breast cancer, there was still no significant difference in OS, LRFS, or disease-free survival. In conclusion, MRI does not seem necessary in all patients undergoing BCS. New prospective randomized controlled trials are needed to determine appropriate use of preoperative MRI and its effects on oncologic outcomes in early breast cancer patients.

The effect of multifocal and multicentric tumours on local recurrence and survival outcomes in breast cancer.

PURPOSE: The purpose of this study was to compare the multifocal (MF)/multicentric (MC) breast cancers with unifocal (UF) breast cancers in terms of tumour characteristics, treatment methods, loco-regional recurrence and survival rates. METHODS: Patients who were treated with a diagnosis of early-stage breast cancer (stage I,II) and had regular follow-up were included in the study. MF tumours were defined as having more than one tumour focus in the same quadrant, whereas MC tumours refered to the presence of more than one tumour focus in different quadrants. RESULTS: In total, 1865 patients with invasive breast cancer were evaluated, 1493 (80.1%) of whom had UF cancer, 330 (17.7%) had MF cancer, and 42 (2.3%) had MC cancer. After comparing the groups with each other, it was seen that MF and MC breast cancers occurred more often at early ages and that lymph node invasion (LNI) was greater. No differences were seen between the 3 groups in terms of local recurrence-free survival (RFS) and overall survival (OS) rates . In multivariate analysis, it was found that MF and MC tumours had no impact on local recurrence and OS. In multivariate analysis, it was understood that HER2 positivity and triple-negative breast cancer (TNBC) had an impact on local recurrence, and age, lymphovascular invasion (LVI), T3 tumour, lymph node positivity and TNBC subtype had an impact on OS. CONCLUSION: Although MC and MF tumours show aggressive features such as high lymph node positivity and LVI, they have similar loco-regional recurrence and survival rates to UF tumours.

Pre-Treatment and Post-Treatment Anxiety, Depression, Sleep and Sexual Function Levels in Patients with Breast Cancer.

OBJECTIVE: In the phase of diagnosis and treatment of breast cancer cases, patients can usually experience sexual dysfunctions, sleep disorders and psychiatric disorders such as anxiety and depression. The main objective of our research is to study of the pre-treatment and post-treatment anxiety, depression, sleep and sexual function levels in the patients with breast cancer. MATERIALS AND METHODS: Fifty-six patients with breast cancer and 52 healthy women have participated in our study. In order to determine the anxiety, depression, sleep and sexual function levels, Sociodemographic and Clinical Data Form, Hospital Anxiety Depression Scale (HADS), Pittsburgh Sleep Quality Scale (PSQI) and Arizona Sexual Experiences Scale (ASEX) scores are utilized at pre-treatment and post-treatment phases for patients with breast cancer and our control group. RESULTS: According to scale scores applied to patients and control group, it has been determined that patients with breast cancer HADS sexual and sleep disorders, that their HADS and PSQI scores were higher and that ASEX scores decreased significantly (p<0.05). According to the scale scores calculated before and after treatment, there was a significant decrease in HADS and PSQI scores, whereas SEX scores have been increased significantly (p<0.05). CONCLUSION: According to the findings of our study, anxiety, depression, sexual dysfunction and sleep disorders in patients with breast cancer are far more explicit in the pre-treatment phase than post-treatment phase. Therefore, it is crucial to psycho-socially support patients with breast cancer in the early periods before starting the treatment after diagnosis.

Comparison of breast cancer patients who underwent partial mastectomy (PM) with mini latissimus dorsi flap (MLDF) and subcutaneous mastectomy with implant (M + I) regarding quality of life (QOL), cosmetic outcome and survival rates.

PURPOSE: The latissimus dorsi muscle has long been used in breast cancer (BC) patients for reconstruction. This study aimed to compare early stage BC patients who had partial mastectomy (PM) with mini latissimus dorsi flap (MLDF) and subcutaneous mastectomy with implant (MI) with respect to quality of life (QoL), cosmetic outcome (CO), and survival rates. PATIENTS AND METHODS: The data of patients who underwent PM + MLDF (Group 1) and M + I (Group 2) between January 2010 and January 2018 were evaluated. Both groups were compared in terms of demographics, clinical and pathological characteristics, surgical morbidity, survival, quality of life, and cosmetic results. The EORTC-QLQ C30 and EORTC-QLO BR23 questionnaires and the Japanese Breast Cancer Society (JBCS) Cosmetic Evaluation Scale were used to assess the quality of life and the cosmetic outcome, respectively. RESULTS: A total of 317 patients were included in the study, 242 (76.3%) of them in group 1 and 75 (23.6%) of them in group 2. Median follow-up time was 56 (14-116) months. There were no differences identified between the groups in terms of tumor histology, hormonal receptors and HER-2 positivity, surgical morbidity, and 5-year overall and disease-free survival. Group 2 patients were significantly younger than group 1 (p = 0.003). The multifocality/multicentricity rate was higher in group 2 (p ≤ 0.001), whereas tumor size (p = 0.009), body mass index (BMI, p = 0.006), histological grade (p ≤ 0.001), lymph node positivity (p = 0.002), axillary lymph node dissection (ALND) rate (p = 0.005), and presence of lympho-vascular invasion (LVI, p = 0.013) were significantly higher in group 1. When the quality of life was assessed by using the EORTC QLQ C30 and BR23 questionnaires, it was seen that the body image perception (p < 0.001) and nausea/vomiting score (p = 0.024) were significantly better in PM + MLDF group whereas physical function score was significantly better in M + I group (p = 0.012). When both groups were examined in terms of cosmesis with JBCS Cosmetic Evaluation Scale, good cosmetic evaluation score was significantly higher in patients in MLDF group (p = 0.01). DISCUSSION: The results of this study indicate that in comparison to M + I procedure, the PM + MLDF procedure provides significantly superior results in terms of body image and cosmetic result with similar morbidity and oncologic outcomes. In selected patients with small breasts and a high tumor/breast ratio, PM + MLDF may be an alternative to subcutaneous mastectomy and implant.

The Effect of Mini-Latissimus Dorsi Flap (MLDF) Reconstruction on Shoulder Function in Breast Cancer Patients.

OBJECTIVE: The aim of this study is to investigate the effect of mini latissimus dorsi flap (MLDF) reconstruction on ipsilateral shoulder functions. MATERIALS AND METHODS: Those included in the study are the patients aged between 23 and 73, who were operated with the diagnosis of early breast cancer (cT1-3)N0). The first group includes the patients who had sentinel lymph node biopsy (SLNB) with partial mastectomy. The second group consists of the patients who had axillary lymph nodule dissection (ALND) with partial mastectomy. The third group includes the patients who had SLNB and MLDF with partial mastectomy. The fourth group includes the patients who had ALND and MLDF with partial mastectomy. Patients' Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) score work model point were recorded. RESULTS: 174 patients were included in this study. According to Q-DASH score, no functional change was detected in 69.5% of the patients, whereas slight functional loss was identified in 23.6%, moderate functional loss in 5.7%, severe functional loss 1.1%. In the comparison of Q-DASH scores in surgery groups, while these four groups were being analyzed, a significant difference was determined (p=0.007). When dual analyses were made, it was also established that the difference resulted from the group to which ALND and MLDF were applied together. CONCLUSION: We conclude that MLDF application for reconstruction purposes after breast surgery has a negative impact on shoulder functions of the patients who had both of partial mastectomy and ALND.

Prognostic Significance of Adjuvant Chemotherapy Induced Amenorrhea in Luminal A and B Subtypes.

OBJECTIVE: In this retrospective study, chemotherapy induced amenorrhea in patients with early stage breast cancer and its effects on survival were investigated. MATERIALS AND METHODS: Two hundred fifty-two patients received adjuvant chemotherapy without ovarian suppression treatment (OST) from 600 premenopausal patients were included in the study. Patients were divided into two groups; with amenorrhea and without, and compared with clinicopathologic features and survival. SPSS version 17 was used. RESULTS: Chemotherapy-induced amenorrhea (CIA) was observed in 145 (57.5%) of 252 patients who received no OST during follow-up. The 5-year OS rate of patients with CIA was significantly higher than patients without CIA (p= 0.042, 95.9% vs. 89.7% vs. 158.88 vs. 135.33 months, respectively). In the subgroup analysis, the OS in patients with hormone receptor (+) was significantly higher than in those receptor (-) in patients with CIA (p=0.011, 97.5% vs. 90.9% vs. 162.13 vs. 126.16 months, respectively). The OS was significantly longer in the luminal A molecular subtype than in those with luminal B molecular subtype, in patients with CIA, but the difference was not significant in patients without CIA (p=0.027 vs. p=0.074, respectively). CONCLUSION: As a conclusion; survival advantage of the chemotherapy induced amenorrhea more pronounced with hormone receptor positivity, lymph node involvement, and advanced disease over patients who do not develop amenorrhea. This advantage of amenorrhea development further prolongs survival compared with luminal B in the luminal A molecular subtype.

Impact of Personality Traits, Anxiety, Depression and Hopelessness Levels on Quality of Life in the Patients with Breast Cancer.

OBJECTIVE: The aim of this study was to investigate the impacts of personality traits, anxiety, depression and hopelessness levels on quality of life in the patients with breast cancer. MATERIALS AND METHODS: The study was performed on 90 patients diagnosed with breast cancer and 90 healthy women. Sociodemographic and Clinical Data Collection Form designed by us, Beck Hopelessness Scale (BHS), Beck Anxiety Scale (BAS), Beck Depression Scale (BDS), Eysenck Personality Inventory (EPI) and Quality of Life Scale-Short Form (SF-36) were administered to patients and to control group. RESULTS: The patients with breast cancer were found to indicate higher levels of anxiety and depression, lower levels of quality of life, and higher scores of personality inventory subscales as compared to the healthy control group. In the patient group, it was identified that the quality of life subscale scores were found to be negatively correlated with anxiety, depression, hopelessness and neurotic personality scores; there was a positive correlation between neurotic personality scores and depression, anxiety and hopelessness scores. CONCLUSIONS: It can be concluded that the breast cancer patients with extraversion personality traits have lower levels of anxiety and depression, keeping their quality of life better, whereas the patients with higher neuroticism scores may have more impaired quality of life. Therefore, the psychiatric evaluation of the breast cancer patients during and after the treatment cannot be ruled out.

Synchronous and metachronous bilateral breast cancer: A long-term experience.

PURPOSE: The objective of this study was to assess the demographic, pathologic and survival characteristics of patients who were diagnosed as having bilateral breast cancer. METHODS: A review was conducted of the records pertaining to patients who presented to our clinic and were diagnosed as having breast cancer. Any second cancer diagnosed within 12 months of initial diagnosis was defined as synchronous bilateral breast cancer. Assessment included treatments administered to the patients and survival rates, as well as their demographic, reproductive and pathologic features. RESULTS: The total number of patients who were diagnosed as having bilateral breast cancer in the context of the present study was 99. Among the patients with synchronous breast cancer, the median age at the time of initial diagnosis was found as 57 years. The median age of the discovery of first tumor among the patients with metachronous tumor was 52 years and the median age of second tumor detection was 59 years. Family history in metachronous tumor was significantly greater (p=0.041). The median time of metachronous cancer incidence was 96 months. The length of disease-free period among the patients with synchronous tumor was 126.3 months, whereas it was 243.7 months in those with metachronous tumor (p=0.041). CONCLUSION: The incidence rate of synchronous breast tumors has been rising thanks to growing awareness and the leading-edge imaging methods. The fact that the second tumor developed after more than 5 years among the patients with metachronous cancer gave rise to the increased rate of survival.

Replacement of the tumor bed following oncoplastic breast-conserving surgery with immediate latissimus dorsi mini-flap.

The aim of the present study was to evaluate the geographic variability of the tumor bed following oncoplastic breast-conserving surgery (OP-BCS), and to assess its relevance for radiotherapy planning. In this prospective study, pre- and postoperative computerized tomography (CT) scans of 22 patients with early-stage breast cancer were fused. The preoperative gross tumor volume or excisional biopsy cavity were contoured under the guidance of preoperative radiological images. Postoperative lumpectomy cavities were contoured under the guidance of surgical clips. The conformity index (CI) was calculated and defined on a scale between 0 and 1, where 0 indicated no overlap and 1 indicated 100% concordance. Associations between CI and the number of clips, time interval between surgery and CT scans, pathological tumor size and age were assessed using independent sample testing. The median CI was 0.07 (in five cases, 1, and in eight cases, 0). The lumpectomy cavity shifted from the primary location in 36.4% of the cases. Median shifts between the isocenters of pre- and postoperative volumes were measured as 1.02 cm (range, 0.4-4.43 cm) in the x, 1.07 cm (range, 0.05-5.67 cm) in the y, and 1.12 cm (range, 0-3.75 cm) in the z directions. Only the clip number was determined to be significantly associated with CI (P=0.017). Pre- and postoperative tumor bed volumes were fully superposed in five of the 22 cases. The present study has shown that the tumor bed is markedly replaced following OP-BCS with latissimus dorsi mini-flap (LDMF) reconstruction. Special care should therefore be taken when defining the lumpectomy cavity following OP-BCS with LDMF reconstruction.

The Prognostic Impact of Molecular Subtypes and Very Young Age on Breast Conserving Surgery in Early Stage Breast Cancer.

BACKGROUND: Premenopausal breast cancer with a triple-negative phenotype (TNBC) has been associated with inferior locoregional recurrence free survival (LRFS) and overall survival (OS) after breast conserving surgery (BCS). The aim of this study is to analyze the association between age, subtype, and surgical treatment on survival in young women (≤40 years) with early breast cancer in a population with a high rate of breast cancer in young women. METHODS: Three hundred thirty-two patients ≤40 years old with stage I-II invasive breast cancer who underwent surgery at a single institution between 1998 and 2012 were identified retrospectively. Uni- and multivariate analysis evaluated predictors of LRFS, OS, and disease free survival (DFS). RESULTS: Most patients (64.2%) underwent BCS. Mean age and follow-up time were 35 (25 ± 3.61) years, and 72 months (range, 24-252), respectively. In multivariate analysis, multicentricity/multifocality and young age (<35 years) independently predicted for poorer DFS and OS. Those aged 35-40 years had higher LRFS and DFS than those <35 in the mastectomy group (p=0.007 and p=0.039, respectively). Patients with TNBC had lower OS compared with patients with luminal A subtype (p=0.042), and those who underwent BCS had higher OS than patients after mastectomy (p=0.015). CONCLUSION: Young age (< 35 years) is an independent predictor of poorer OS and DFS as compared with ages 35-40, even in countries with a lower average age of breast cancer presentation. In addition, TNBC in the young predicts for poorer OS. BCS can be performed in young patients with TNBC, despite their poorer overall survival.

Prognostic relevance of sunitinib toxicities and comparison of continuous vs. intermittent sunitinib dosing schedule in metastatic renal cell cancer patients.

AIM OF THE STUDY: Sunitinib-related side effects may develop as a result of the pharmacokinetic pathway affects the of the drug. MATERIAL AND METHODS: Data on mRCC patients were obtained from the hospital archives. Outcomes of patients were evaluated in terms of related prognostic factors, sunitinib adverse events during the treatment, and two different sunitinib dosing schedules. RESULTS: Seventy patients diagnosed with mRCC and treated with sunitinib were analyzed for prognostic factors and survival rates. During the mean follow-up of 33.5 months, 38 (54%) patients were alive and 32 (46%) patients died. The median time of overall survival (OS) and progression-free survival (PFS) was 27 months (12-61) and 19 months (5-45), respectively. In univariate analysis, good prognostic risk group according to the Memorial Sloan-Kettering Cancer Center (MSKCC), hypothyroidism as sunitinib toxicity and patients on sunitinib treatment more than 1 year were favorable prognostic factors for OS. Leukopenia and fatigue as sunitinib toxicity were poor prognostic factors for OS. PFS and OS of the patients were not significantly different when we compared intermittent (4/2) vs. continuous treatment dosing schedules. CONCLUSIONS: As a result of this trial, having hypothyroidism as an adverse effect of sunitinib was a favorable prognostic factor for OS and PFS in mRCC patients. It was also found that 4/2 and continuous dosing schedules of sunitinib did not give rise to different outcomes in mRCC patients.

True Local Recurrences after Breast Conserving Surgery have Poor Prognosis in Patients with Early Breast Cancer.

BACKGROUND: This study was aimed at investigating clinical and histopathologic features of ipsilateral breast tumor recurrences (IBTR) and their effects on survival after breast conservation therapy. METHODS: 1,400 patients who were treated between 1998 and 2007 and had breast-conserving surgery (BCS) for early breast cancer (cT1-2/N0-1/M0) were evaluated. Demographic and pathologic parameters, radiologic data, treatment, and follow-up related features of the patients were recorded. RESULTS: 53 patients (3.8%) had IBTR after BCS within a median follow-up of 70 months. The mean age was 45.7 years (range, 27-87 years), and 22 patients (41.5%) were younger than 40 years. 33 patients (62.3%) had true recurrence (TR) and 20 were classified as new primary (NP). The median time to recurrence was shorter in TR group than in NP group (37.0 (6-216) and 47.5 (11-192) months respectively; p = 0.338). Progesterone receptor positivity was significantly higher in the NP group (p = 0.005). The overall 5-year survival rate in the NP group (95.0%) was significantly higher than that of the TR group (74.7%, p < 0.033). Multivariate analysis showed that younger age (<40 years), large tumor size (>20 mm), high grade tumor and triple-negative molecular phenotype along with developing TR negatively affected overall survival (hazard ratios were 4.2 (CI 0.98-22.76), 4.6 (CI 1.07-13.03), 4.0 (CI 0.68-46.10), 6.5 (CI 0.03-0.68), and 6.5 (CI 0.02- 0.80) respectively, p < 0.05). CONCLUSIONS: Most of the local recurrences after BCS in our study were true recurrences, which resulted in a poorer outcome as compared to new primary tumors. Moreover, younger age (<40), large tumor size (>2 cm), high grade, triple negative phenotype, and having true recurrence were identified as independent prognostic factors with a negative impact on overall survival in this dataset of patients with recurrent breast cancer. In conjunction with a more intensive follow-up program, the role of adjuvant therapy strategies should be explored further in young patients with large and high-risk tumors to reduce the risk of TR.

A Rare Case of Sunitinib-Induced Hyperammonemic Encephalopathy and Hypothyroidism in Metastatic Renal Cell Carcinoma.

Sunitinib has become a standard treatment agent for metastatic renal cell carcinoma (RCC) for several years. However, various adverse events have been reported. We present a rare adverse effect of hyperammonemic encephalopathy induced by sunitinib. A 66-year-old woman with metastatic RCC referred to the emergency department with confusion that developed 14 days after the initiation of 50 mg/d of sunitinib. Her serum ammonia and thyroid-stimulating hormone levels were markedly elevated (146 µg/dL and 27.27 µIU/mL, respectively). Sunitinib was discontinued, and an enema with lactulose and L-thyroxine were administered. Her mental status and neurologic symptoms were normalized 7 days after the treatment. Serum ammonia level decreased to 61 µg/dL and thyroid stimulating hormone level decreased 22.34 µIU/mL. The incidence of sunitinib-induced hyperammonemia is rarely reported. The relationship between sunitinib and the development of hyperammonemia is not well understood, and the mechanism is unclear. Sunitinib-induced hyperammonemia is very rare, and to the best of our knowledge, this is fourth case hyperammonemia and first case hyperammonemic encephalopathy with hypothyroidism as an adverse effect. Therefore, it is important for clinicians to be aware of hyperammonemia that can occur in several days after the initiation of sunitinib treatment in metastatic RCC.

A Rare Tumor that Mimicked Metastasis in a Patient with Breast Cancer: Epithelioid Hemangioendothelioma.

A woman aged 50 years was diagnosed as having an invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast and underwent bilateral mastectomy eight years ago. A mass was identified during follow-up in positron-emission tomography (PET) image in the left infraclavicular region, indicating metastasis. Histopathologic examination showed a mass of 1.9 × 1 × 0.7 cm in dimensions characterized by spindle or round nuclei cells that formed island or cords in hyaline and myxoid ground and intracytoplasmic vacuoles containing erythrocytes. In the immunohistochemical analysis, tumor cells were widespread with diffuse positivity with CD34 and vimentin. These findings redirected us from a diagnosis of metastatic carcinoma to epithelioid hemangioendothelioma, a rare tumor of intermediate vascular tumor groups. In this respect, confirmation through biopsy from considered cases of metastasis is important in making a definite pathologic differential diagnosis.

Dramatic Response to Catumaxomab Treatment for Malign Ascites Related to Renal Cell Carcinoma With Sarcomotoid Differentiation.

Refractory malignant ascites (MA) is a common complication in cancer patients. Renal cell carcinoma (RCC) is rarely present with peritoneal ascites, which is commonly associated with carcinomas of the gastrointestinal and female reproductive tracts; including especially ovarian high-grade serous carcinoma. Currently, chemotherapy and paracentesis represent the most widely used methods to relieve the symptoms. Recently, intraperitoneal therapy with catumaxomab-a trifunctional hybrid antibody-has been introduced for the treatment of MA. The benefit of this treatment has been demonstrated in patients with distinct abdominal malignancies. In this case report, we present the first case of successful catumaxomab treatment against MA in a patient with advanced RCC with sarcomatoid differentiation. After the second administration of catumaxomab, paracentesis became no longer necessary. Catumaxomab might represent a safe treatment option for MA in the course of metastatic RCC with sarcomatoid differentiation.

Bioelectrical impedance for detecting and monitoring lymphedema in patients with breast cancer. Preliminary results of the florence nightingale breast study group.

The aim of this study was to evaluate the efficacy of bioimpedance spectroscopy for the follow-up of patients with lymphedema in Turkey and its benefits in the diagnosis of stage 0, 1, and 2 lymphedema in patients who are under treatment for breast cancer. Thirty-seven female patients with breast cancer who underwent surgical procedures in our Breast Health Centre were followed up for lymphedema using bioimpedance, and clinical measurements were taken for a minimum period of 1 year at 3-month intervals. Patients who had been monitored regularly between November, 2011, and September, 2013, were enrolled to the study. In total, 8 patients developed lymphedema with an overall rate of 21.6%. Among the 8 patients who developed lymphedema, 4 had Stage 2, 1 had Stage 1, and 3 had Stage 0 lymphedema. Stage 0 lymphedema could not be detected with clinical measurements. During the patients' 1-year follow-up period using measurements of bioimpedance, a statistically significant relationship was observed between the occurrence of lymphedema and the disease characteristics. including the number of the extracted and remaining lymph nodes and the region of radiotherapy (p=0.042, p=0.024, p=0.040). Bioimpedance analysis seems to be a practical and reliable method for the early diagnosis of lymphedema. It is believed that regular monitoring of patients in the high-risk group using bioimpedance analyses increases the ability to treat lymphedema.

Standardisation of the neck-shaft angle and measurement of age-, gender- and BMI-related changes in the femoral neck using DXA.

INTRODUCTION: The morphology of the proximal femur has often been investigated in the literature, but the normal population ranges and standard deviations have still not been determined for this area. This study aimed to determine the age-, gender- and body mass index (BMI)-related changes in the femoral neck, especially on the neck-shaft angle, by using dual-energy X-ray absorptiometry (DXA) measurements. METHODS: Retrospective analyses of DXA images of the proximal femur from 18,943 individuals aged 20-108 years were performed. The age, gender, weight and height of each individual were obtained at the time of bone measurement. Data on theta angle were obtained from DXA measurements. Simple linear regression analysis and Pearson's correlation coefficients were used to investigate the relationships between theta and age, gender and BMI. RESULTS: There was a significant correlation between theta and age (p < 0.001). We also found a significant difference between the various age groups using analysis of variance (p < 0.001), but there was no meaningful correlation between theta and BMI (p = 0.377) and the BMI groups (p = 0.180). There were small but statistically significant differences in the neck-shaft angle between males and females (p < 0.05). CONCLUSION: In this study, DXA-based measurements were used and many parameters of proximal femur geometry were calculated with limited radiation exposure. We have demonstrated that the mean neck-shaft angle is greater in males than in females, and that theta increases with age. We also found a significant difference between different age groups, but no meaningful correlation between theta and BMI.

The relationship between bone mineral density and arterial stiffness in women.

PURPOSE: The aim of this study was to investigate the correlation between bone mineral density (BMD) and arterial stiffness as a preclinical atherosclerosis criterion. MATERIALS AND METHODS: Carotid and femoral artery Doppler ultrasonography and arterial stiffness measurements were performed on 113 female patients referred for BMD measurements. RESULTS: The cross-sectional compliance and cross-sectional distensibility of the carotid artery were positively correlated with the BMD of the Ward's triangle, the femoral neck, and the lower femoral neck; and the Ward's triangle, respectively. A negative correlation was found between the intima-media thickness of the femoral artery and the femoral elastic modulus with the BMD of L1, L12, L13, and L23; and the BMD of L1, L3, L13, L24, L34, the femoral neck, the lower femoral neck, and Ward's triangle, respectively. The cross-sectional compliance and cross-sectional distensibility of the femoral artery were positively correlated with the BMD of the femoral neck, upper femoral neck, lower femoral neck, Ward's triangle; and the BMD of the total femur and Ward's triangle, respectively. CONCLUSION: The arterial stiffness measurements in women are correlated with BMD, regardless of age and other demographic factors.
