Abstract
Low molecular weight heparins (LMWH) and anti-Xa direct oral anti-coagulants (DOACs) are recommended for the long-term treatment of cancer-associated thrombosis (CAT) based on well-documented randomised controlled trials. Anti-Xa DOACs are viewed as a first choice for the treatment of patients with CAT. A large number of drug-drug interactions have been reported between DOACs and chemotherapy drugs, modifying circulating levels of DOAC leading to fears of increased bleeding risks or thrombotic recurrence. Progresses in anti-neoplastic therapies have improved the prognosis and the survival, thus increasing the prevalence of frail patients with cancer. However, since frailties tend to be excluded from large trials due to multiple co-morbidities, current guidelines are not fully applicable to this population. The management of these frail patients with CAT is particularly complex and requires a risk assessment on a case-by-case basis with specific focus on cancer, patient-related risk factors and drug-drug interactions. In this brief review we have identified age, co-morbidities and co-medications as key factors of frailty that require careful attention and we have developed a therapeutic decision algorithm to help clinicians optimising the use of anti-coagulants in patients with cancer with CAT, especially in case of anti-Xa DOACs concomitant medications. With the evaluation of the bleeding risk according to the type of cancer, and anticipating drug-drug interactions intensity, taking into account patient frailties allows the optimisation of the anti-coagulant choice. A systematic collaboration between oncologists, vascular pathology specialists and pharmacists is warranted to ensure an optimal patient management. Clinical studies are needed to determine the real impact of these interactions.

LeVee A, Mortimer J. The Challenges of Treating Patients with Breast Cancer and Obesity. Cancers (Basel) 2023; 15:cancers15092526. [PMID: 37173991 PMCID: PMC10177120 DOI: 10.3390/cancers15092526] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 04/23/2023] [Accepted: 04/26/2023] [Indexed: 05/15/2023] Open
Abstract
Obesity is defined as a body mass index (BMI) of 30 kg/m2 or more and is associated with worse outcomes in patients with breast cancer, resulting in an increased incidence of breast cancer, recurrence, and death. The incidence of obesity is increasing, with almost half of all individuals in the United States classified as obese. Patients with obesity present with unique pharmacokinetics and physiology and are at increased risk of developing diabetes mellitus and cardiovascular disease, which leads to specific challenges when treating these patients. The aim of this review is to summarize the impact of obesity on the efficacy and toxicity of systemic therapies used for breast cancer patients, describe the molecular mechanisms through which obesity can affect systemic therapies, outline the existing American Society of Clinical Oncology (ASCO) guidelines for treating patients with cancer and obesity, and highlight additional clinical considerations for treating patients with obesity and breast cancer. We conclude that further research on the biological mechanisms underlying the obesity-breast cancer link may offer new treatment strategies, and clinicals trials that focus on the treatment and outcomes of patients with obesity and all stages of breast cancer are needed to inform future treatment guidelines.

Curr Oncol 2023; 30:1831-1843. [PMID: 36826103 PMCID: PMC9955032 DOI: 10.3390/curroncol30020142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 01/27/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023] Open
Abstract
Cardiovascular disease (CVD) is one of the most common comorbidities in breast cancer survivors. Recently, the target population and treatment period for aromatase inhibitor (AI) treatment in breast cancer patients has been expanding. However, information on adverse CVD events from the long-term use of AI is still lacking. The aim of this study was to investigate the CVD side effects of AI treatment and to evaluate the changes in lipid profile during AI treatment. A systematic search of PubMed (Medline), EMBASE, and Cochrane Library databases reporting on cardiovascular outcomes or lipid profiles change in adult female breast cancer patients (>19 years old) with AI was performed. The pooled analysis of 25 studies showed that the prevalence rate of any type of cardiovascular disease was 6.08 per 100 persons (95% CI 2.91-10.31). Angina was the most common type of heart-related cardiovascular event accounting for 3.85 per 100 persons, followed by any type of stroke (3.34) and venous thromboembolism (2.95). Ischemic stroke (OR 1.39, 95% CI 1.07-1.81) and myocardial infarction (OR 1.30, 95% CI 0.88-1.93) were more common in AI compared with tamoxifen, whereas the prevalence of venous thromboembolism (OR 0.61, 95% CI 0.37-1) was significantly lower in the AI group. In addition, treatment with AI for 6-12 months showed a decrease in HDL-cholesterol and an increase in LDL-cholesterol and total cholesterol. Various CVDs can occur when using AI, and in particular, the risk of MI and ischemic stroke increases in comparison with the adverse effect of tamoxifen. The occurrence of CVD might be related to the deterioration of the lipid profile after AI treatment. Therefore, a customized individualization strategy considering each patient's CV risk factors is needed during AI treatment.

Reassessing the Benefits and Harms of Risk-Reducing Medication Considering the Persistent Risk of Breast Cancer Mortality in Estrogen Receptor-Positive Breast Cancer. J Clin Oncol 2023; 41:859-870. [PMID: 36455167 PMCID: PMC9901948 DOI: 10.1200/jco.22.01342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 09/26/2022] [Accepted: 10/19/2022] [Indexed: 12/03/2022] Open
Abstract
PURPOSE Recent studies, including a meta-analysis of 88 trials, have shown higher than expected rates of recurrence and death in hormone receptor-positive breast cancer. These new findings suggest a need to re-evaluate the use of risk-reducing medication to avoid invasive breast cancer and breast cancer death in high-risk women. METHODS We adapted an established Cancer Intervention and Surveillance Modeling Network model to evaluate the lifetime benefits and harms of risk-reducing medication in women with a ≥ 3% 5-year risk of developing breast cancer according to the Breast Cancer Surveillance Consortium risk calculator. Model input parameters were derived from meta-analyses, clinical trials, and large observational data. We evaluated the effects of 5 years of risk-reducing medication (tamoxifen/aromatase inhibitors) with annual screening mammography ± magnetic resonance imaging (MRI) compared with no screening, MRI, or risk-reducing medication. The modeled outcomes included invasive breast cancer, breast cancer death, side effects, false positives, and overdiagnosis. We conducted subgroup analyses for individual risk factors such as age, family history, and prior biopsy. RESULTS Risk-reducing tamoxifen with annual screening (± MRI) decreased the risk of invasive breast cancer by 40% and breast cancer death by 57%, compared with no tamoxifen or screening. This is equivalent to an absolute reduction of 95 invasive breast cancers, and 42 breast cancer deaths per 1,000 high-risk women. However, these drugs are associated with side effects. For example, tamoxifen could increase the number of endometrial cancers up to 11 per 1,000 high-risk women. Benefits and harms varied by individual characteristics. CONCLUSION The addition of risk-reducing medication to screening could further decrease the risk of breast cancer death. Clinical guidelines for high-risk women should consider integrating shared decision making for risk-reducing medication and screening on the basis of individual risk factors.

Abstract
Over the last decade, cancer mortality has decreased considerably, particularly in breast cancer thanks to better screening techniques and better therapeutic management. The significant increase in patient survival has led to the appearance of a certain number of events due to the side effects of the therapies used. Cardiovascular disease is the most frequently observed side effect in breast cancer, due to the direct toxicity of anti-cancer therapies but also due to traditional cardiovascular risk factors common to both of diseases. Anthracyclines, anti-HER2 therapies, chest radiotherapy and hormone therapy are the main causes of cardiotoxicity in breast cancer. It is important to know the rate of follow-up for cardiotoxicity screening and management.

Abstract
Survival in cancer is continuously improving due to evolving oncological treatment. Therefore, cardiovascular short-term and long-term side effects gain crucial importance for overall outcome. Cardiotoxicity not only presents as heart failure, but also as treatment-resistant hypertension, acute coronary ischemia with plaque rupture or vasospasm, thromboembolism, arrhythmia, pulmonary hypertension, diastolic dysfunction, acute myocarditis and others. Recent recommendations have proposed baseline cardiac risk assessment and surveillance strategies. Major challenges are the availability of monitoring and imaging resources, including echocardiography with speckle tracking longitudinal strain (GLS), serum biomarkers such as natriuretic peptides (NT-proBNP) and highly sensitive cardiac troponins. This Austrian consensus encompasses cardiotoxicity occurrence in frequent antiproliferative cancer drugs, radiotherapy, immune checkpoint inhibitors and cardiac follow-up considerations in cancer survivors in the context of the Austrian healthcare setting. It is important to optimize cardiovascular risk factors and pre-existing cardiac diseases without delaying oncological treatment. If left ventricular ejection fraction (LVEF) deteriorates during cancer treatment (from >10% to <50%), or myocardial strain decreases (>15% change in GLS), early initiation of cardioprotective therapies (angiotensin-converting enzyme inhibitors, angiotensin or beta receptor blockers) is recommended, and LVEF should be reassessed before discontinuation. Lower LVEF cut-offs were recently shown to be feasible in breast cancer patients to enable optimal anticancer treatment. Interdisciplinary cardio-oncology cooperation is pivotal for optimal management of cancer patients.

Abstract
(1) Background: The fundamental causes of breast cancer mortality are the cancer spread and hypercoagulability state. The study aimed to evaluate the prognostic efficacy of the fibrinolytic profile concerning 5-year follow-up. (2) Methods: We investigated the predictive potential of the plasma activity of urokinase plasminogen activator (u-PA) and plasminogen activator inhibitor type 1 (PAI-1) as well as antigen of tissue plasminogen activator (t-PA), u-PA, PAI-1, and PAI-1/t-PA and PAI-1/u-PA complexes in 41 breast cancer patients. The median follow-up was 66 months, with full evidence of the first event. (3) Results: A significantly lower level of PAI-1 antigen was noted in IBrC patients with lymph node involvement (N1) than in patients with free lymph node metastases (N0). According to ROC curve analysis, a t-PA antigen was the strongest predictor of disease relapse (the area under the curve, AUC = 0.799; p < 0.0006). Patients with PAI-1 activity < 3.04 U/mL had significantly better disease-free survival (DFS) compared to those with PAI-1 activity > 3.04 U/mL. Patients with both t-PA antigen lower than 1.41 ng/mL (cut-off according to median value) and lower than 1.37 ng/mL (cut-off according to ROC curve) had significantly shorter DFS (p = 0.0086; p = 0.0029). (4) Conclusions: The results suggest that a higher plasma t-PA antigen level or lower PAI-1 activity are linked to better outcomes in breast cancer patients.

Abstract
Hormone receptor positivity and early stage diagnosis are generally considered signs of good prognosis in breast cancer. However, breast cancer all too frequently can become resistant to hormone-based therapies, and women can experience recurrence of their breast cancer decades after the diagnosis of early stage disease. To address the therapeutic needs for advanced and metastatic hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-) breast cancer, a number of new drugs have been tested and approved for this indication, including the class of drugs that works as cyclin-dependent kinase (CDK) 4/6 inhibitors. These drugs, often combined with other hormone-based therapy, have demonstrated considerable success in clinical trials and are now being used widely in oncology practices. Because all of the currently approved CDK4/6 inhibitor agents (palbociclib, ribociclib, and abemaciclib) are given orally, issues of patient comprehension of and adherence to prescribed regimens should be at the forefront of practitioners' concerns about these drugs. In addition, ways to support and facilitate decision-making by patients related to this class of agents and other therapies recently approved for the same indication require focused attention by health-care providers. Oncology has continued to move toward a more patient-specific, precision medicine approach. Likewise, advanced practitioners have the opportunity to identify patient characteristics, preferences, and needs that are unique to individual patients to enhance precision treatment.

Abstract
PURPOSE OF REVIEW Long-term survival has increased significantly in breast cancer patients, and cardiovascular side effects are surpassing cancer-related mortality. We summarize risk factors, prevention strategies, detection, and management of cardiotoxicity, with focus on left ventricular dysfunction and heart failure, during breast cancer treatment. RECENT FINDINGS Baseline treatment of cardiovascular risk factors is recommended. Anthracycline and trastuzumab treatment constitute a substantial risk of developing cardiotoxicity. There is growing evidence that this can be treated with beta blockers and angiotensin antagonists. Early detection of cardiotoxicity with cardiac imaging and circulating cardiovascular biomarkers is currently evaluated in clinical trials. Chest wall irradiation accelerates atherosclerotic processes and induces fibrosis. Immune checkpoint inhibitors require consideration for surveillance due to a small risk of severe myocarditis. Cyclin-dependent kinases4/6 inhibitors, cyclophosphamide, taxanes, tyrosine kinase inhibitors, and endocrine therapy have a lower-risk profile for cardiotoxicity. Preventive and management strategies to counteract cancer treatment-related left ventricular dysfunction or heart failure in breast cancer patients should include a comprehensive cardiovascular risk assessment and individual clinical evaluation. This should include both patient and treatment-related factors. Further clinical trials especially on early detection, cardioprevention, and management are urgently needed.

Abstract
Tamoxifen shows efficacy in reducing breast cancer-related mortality but clinically, is associated with increased risk for thromboembolic events. We aimed to determine whether breast tumour sub-phenotype could predict propensity for thrombosis. We present two ex vivo Models of Tamoxifen-therapy, Model 1 in which treatment recapitulates accumulation within breast tissue, by treating MCF7 and T47D cells directly prior to exposure to blood constituents; and Model 2 in which we recreate circulating Tamoxifen by treating blood constituents prior to exposure to cancer cells. Blood constituents included whole blood, platelet-rich plasma and platelet-poor plasma. Hypercoagulation was assessed as a function of thrombin activity, expression of CD62P and CD63 activation markers defined as an index of platelet activation, and platelet morphology; while oestrogen receptor expression was assessed using immunocytochemistry with quantitative analysis. We determined, in concert with clinical studies and contrary to selected laboratory investigations, that Tamoxifen induces hypercoagulation, dependent on sub-phenotypes, with the T47D cell line capacity most enhanced. We determined a weak positive correlation between oestrogen receptor expression, and CD62P and CD63; indicating an association between tumour invasion profiles and hypercoagulation, however, other yet unknown factors may play a predictive role in defining hypercoagulation.

Abstract
The challenge of effective management of ductal carcinoma in situ (DCIS) and other pre-malignant disorders of the breast is to select patients who will not progress to invasive carcinoma from those at the highest risk who require radiotherapy and/or endocrine therapy to minimize the risk of a subsequent invasive recurrence. Although IBIS-II and NSABP-B35 DCIS phase III trials proved that tamoxifen 20 mg/day and anastrozole reduce the risk of ipsilateral and contralateral events, the toxicities of both drugs have hampered the drug uptake by high-risk women. We recently reported results of a 3-year placebo-controlled trial of low-dose (5 mg/d) tamoxifen in 500 women with intraepithelial neoplasia (70% DCIS). At a median follow-up of 5 years, women randomly assigned to low-dose tamoxifen had half the number of subsequent diagnoses of DCIS or invasive cancer compared with those randomly assigned to placebo but no increase in thromboembolic events or endometrial cancers. The 5-year number needed to treat was 22 (95% CI, 20-27). Our attention is now focused on prognostic and predictive markers to identify patients who can derive the greatest benefits from low dose tamoxifen, such as for instance the expression of 23 genes involved in cell cycle progression (CCP). In conclusion, we endorse an active treatment of DCIS as the standard of care.

Abstract
Endocrine therapy is an effective option for the treatment of estrogen receptor alpha (ERα)-positive breast cancers. Unfortunately, a large fraction of women relapse with endocrine-resistant tumors. The presence of constitutively active ERα mutants, found in a subset of relapse tumors, is thought to be an important endocrine resistance mechanism and has prompted the search for more effective anti-hormone drugs that can effectively inhibit these mutant versions of the receptor. The G protein-coupled estrogen receptor (GPER) is also thought to contribute to the development of endocrine resistance, in part, due to its activation by clinically used selective estrogen receptor modulators and downregulators (SERMs/SERDs). Therefore, next-generation drugs should be screened for potential activity towards GPER. Here, we highlight the need for truly ERα-selective SERMs and SERDs that do not cross-react with GPER for the treatment of ERα-positive breast cancers.

Abstract
IMPORTANCE Breast cancer is the most common nonskin cancer among women in the United States and the second leading cause of cancer death. The median age at diagnosis is 62 years, and an estimated 1 in 8 women will develop breast cancer at some point in their lifetime. African American women are more likely to die of breast cancer compared with women of other races. OBJECTIVE To update the 2013 US Preventive Services Task Force (USPSTF) recommendation on medications for risk reduction of primary breast cancer. EVIDENCE REVIEW The USPSTF reviewed evidence on the accuracy of risk assessment methods to identify women who could benefit from risk-reducing medications for breast cancer, as well as evidence on the effectiveness, adverse effects, and subgroup variations of these medications. The USPSTF reviewed evidence from randomized trials, observational studies, and diagnostic accuracy studies of risk stratification models in women without preexisting breast cancer or ductal carcinoma in situ. FINDINGS The USPSTF found convincing evidence that risk assessment tools can predict the number of cases of breast cancer expected to develop in a population. However, these risk assessment tools perform modestly at best in discriminating between individual women who will or will not develop breast cancer. The USPSTF found convincing evidence that risk-reducing medications (tamoxifen, raloxifene, or aromatase inhibitors) provide at least a moderate benefit in reducing risk for invasive estrogen receptor-positive breast cancer in postmenopausal women at increased risk for breast cancer. The USPSTF found that the benefits of taking tamoxifen, raloxifene, and aromatase inhibitors to reduce risk for breast cancer are no greater than small in women not at increased risk for the disease. The USPSTF found convincing evidence that tamoxifen and raloxifene and adequate evidence that aromatase inhibitors are associated with small to moderate harms. Overall, the USPSTF determined that the net benefit of taking medications to reduce risk of breast cancer is larger in women who have a greater risk for developing breast cancer. CONCLUSIONS AND RECOMMENDATION The USPSTF recommends that clinicians offer to prescribe risk-reducing medications, such as tamoxifen, raloxifene, or aromatase inhibitors, to women who are at increased risk for breast cancer and at low risk for adverse medication effects. (B recommendation) The USPSTF recommends against the routine use of risk-reducing medications, such as tamoxifen, raloxifene, or aromatase inhibitors, in women who are not at increased risk for breast cancer. (D recommendation) This recommendation applies to asymptomatic women 35 years and older, including women with previous benign breast lesions on biopsy (such as atypical ductal or lobular hyperplasia and lobular carcinoma in situ). This recommendation does not apply to women who have a current or previous diagnosis of breast cancer or ductal carcinoma in situ.

Abstract
IMPORTANCE Medications to reduce risk of breast cancer are effective for women at increased risk but also cause adverse effects. OBJECTIVE To update the 2013 US Preventive Services Task Force systematic review on medications to reduce risk of primary (first diagnosis) invasive breast cancer in women. DATA SOURCES Cochrane Central Register of Controlled Trials and Database of Systematic Reviews, EMBASE, and MEDLINE (January 1, 2013, to February 1, 2019); manual review of reference lists. STUDY SELECTION Discriminatory accuracy studies of breast cancer risk assessment methods; randomized clinical trials of tamoxifen, raloxifene, and aromatase inhibitors for primary breast cancer prevention; studies of medication adverse effects. DATA EXTRACTION AND SYNTHESIS Investigators abstracted data on methods, participant characteristics, eligibility criteria, outcome ascertainment, and follow-up. Results of individual trials were combined by using a profile likelihood random-effects model. MAIN OUTCOMES AND MEASURES Probability of breast cancer in individuals (area under the receiver operating characteristic curve [AUC]); incidence of breast cancer, fractures, thromboembolic events, coronary heart disease events, stroke, endometrial cancer, and cataracts; and mortality. RESULTS A total of 46 studies (82 articles [>5 million participants]) were included. Eighteen risk assessment methods in 25 studies reported low accuracy in predicting the probability of breast cancer in individuals (AUC, 0.55-0.65). In placebo-controlled trials, tamoxifen (risk ratio [RR], 0.69 [95% CI, 0.59-0.84]; 4 trials [n = 28 421]), raloxifene (RR, 0.44 [95% CI, 0.24-0.80]; 2 trials [n = 17 806]), and the aromatase inhibitors exemestane and anastrozole (RR, 0.45 [95% CI, 0.26-0.70]; 2 trials [n = 8424]) were associated with a lower incidence of invasive breast cancer. Risk for invasive breast cancer was higher for raloxifene than tamoxifen in 1 trial after long-term follow-up (RR, 1.24 [95% CI, 1.05-1.47]; n = 19 747). Raloxifene was associated with lower risk for vertebral fractures (RR, 0.61 [95% CI, 0.53-0.73]; 2 trials [n = 16 929]) and tamoxifen was associated with lower risk for nonvertebral fractures (RR, 0.66 [95% CI, 0.45-0.98]; 1 trial [n = 13 388]) compared with placebo. Tamoxifen and raloxifene were associated with increased thromboembolic events compared with placebo; tamoxifen was associated with more events than raloxifene. Tamoxifen was associated with higher risk of endometrial cancer and cataracts compared with placebo. Symptomatic effects (eg, vasomotor, musculoskeletal) varied by medication. CONCLUSIONS AND RELEVANCE Tamoxifen, raloxifene, and aromatase inhibitors were associated with lower risk of primary invasive breast cancer in women but also were associated with adverse effects that differed between medications. Risk stratification methods to identify patients with increased breast cancer risk demonstrated low accuracy.

Abstract
PURPOSE Tamoxifen administered for 5 years at 20 mg/d is effective in breast cancer treatment and prevention, but toxicity has limited its broad use. Biomarker trials showed that 5 mg/d is not inferior to 20 mg/d in decreasing breast cancer proliferation. We hypothesized that a lower dose given for a shorter period could be as effective in preventing recurrence from breast intraepithelial neoplasia but have a lower toxicity than the standard dose. PATIENTS AND METHODS We conducted a multicenter randomized trial of tamoxifen, 5 mg/d or placebo administered for 3 years after surgery in women with hormone-sensitive or unknown breast intraepithelial neoplasia, including atypical ductal hyperplasia and lobular or ductal carcinoma in situ. The primary end point was the incidence of invasive breast cancer or ductal carcinoma in situ. RESULTS Five hundred women 75 years of age or younger were included. After a median follow-up of 5.1 years (interquartile range, 3.9-6.3 years), there were 14 neoplastic events with tamoxifen and 28 with placebo (11.6 v 23.9 per 1,000 person-years; hazard ratio, 0.48; 95% CI, 0.26 to 0.92; P = .02), which resulted in a 5-year number needed to treat of 22 (95% CI, 20 to 27). Tamoxifen decreased contralateral breast events by 75% (three v 12 events; hazard ratio, 0.25; 95% CI, 0.07 to 0.88; P = .02). Patient-reported outcomes were not different between arms except for a slight increase in frequency of daily hot flashes with tamoxifen (P = .02). There were 12 serious adverse events with tamoxifen and 16 with placebo, including one deep vein thrombosis and one stage I endometrial cancer with tamoxifen and one pulmonary embolism with placebo. CONCLUSION Tamoxifen at 5 mg/d for 3 years can halve the recurrence of breast intraepithelial neoplasia with a limited toxicity, which provides a new treatment option in these disorders.

Abstract
Cancer patients have an increased risk of thrombosis. The development of cancer thrombosis is dependent on a number of factors including cancer type, stage, various biologic markers, and the use of central venous catheters. In addition, cancer treatment itself may increase thrombotic risk. Tamoxifen increases the risk of venous thromboembolism (VTE) by two- to sevenfold, while an impact on risk of arterial thrombosis is uncertain. Immunomodulatory imide drugs (IMiDs) such as thalidomide and lenalidomide increase the risk of VTE in patients with multiple myeloma (MM) by about 10-40% when given in combination with glucocorticoids or other chemotherapy agents; the risk of VTE in MM patients treated with IMiD-containing regimens necessitates that such patients receive thromboprophylaxis with aspirin, low-molecular-weight heparin, or warfarin. Among cytotoxic chemotherapy agents, cisplatin, and to a lesser extent fluorouracil, has been described in association with thrombosis. L-asparaginase in treatment of acute lymphoblastic leukemia is significantly associated with increased thrombosis particularly affecting the CNS, which may be due to acquired antithrombin deficiency; at some centers, plasma infusions or antithrombin replacement is used to mitigate this. Bevacizumab, an inhibitor of vascular endothelial growth factor, increases arterial and possibly venous thrombotic risk, although the literature is conflicting about the latter. Supportive care agents in cancer care, such as erythropoiesis-stimulating agents, granulocyte colony stimulating factor, and steroids, also have some impact on thrombosis. This review summarizes the mechanisms by which these and other therapies modulate thrombotic risks and how such risks may be managed.

Abstract
The association between tamoxifen use and risk of deep vein thrombosis or pulmonary embolism in women with breast cancer has been reported in the Western population. The study aimed to evaluate the association between tamoxifen use and deep vein thrombosis or pulmonary embolism in older women with breast cancer in Taiwan.We conducted a retrospective case-control study using the database of the Taiwan National Health Insurance Program. A total of 281 women subjects with breast cancer aged ≥65 years with newly diagnosed deep vein thrombosis/or pulmonary embolism from 2000 to 2011 were identified as the cases. Additionally, 907 women subjects with breast cancer aged ≥65 years without deep vein thrombosis or pulmonary embolism were randomly selected as the controls. The cases and the controls were matched with age and comorbidities. Ever use of tamoxifen was defined as subjects who had at least a prescription for tamoxifen before index date. Never use of tamoxifen was defined as subjects who never had a prescription for tamoxifen before index date. We used the multivariable logistic regression model to calculate the odds ratio (OR) and the 95% confidence interval (CI) of deep vein thrombosis or pulmonary embolism associated with tamoxifen use.After adjustment for confounding variables, the adjusted OR of deep vein thrombosis or pulmonary embolism was 1.95 for subjects with ever use of tamoxifen (95% CI 1.45, 2.62), as compared with never use of tamoxifen. In addition, atrial fibrillation (adjusted OR 3.73, 95% CI 1.89, 7.35) and chronic kidney disease (adjusted OR 1.72, 95% CI 1.06, 2.80) were also associated with deep vein thrombosis or pulmonary embolism.Tamoxifen use is associated with 1.95-fold increased odds of deep vein thrombosis or pulmonary embolism among older women with breast cancer in Taiwan.

Abstract
BACKGROUND The use of hormone therapy (tamoxifen and aromatase inhibitors) has been shown to increase venous thromboembolism. As breast cancer patients undergoing microsurgical breast reconstruction are often receiving hormone therapy, it is unclear whether this increased thrombotic risk is associated with increased flap loss. METHODS A retrospective review was performed on patients undergoing abdominally based microsurgical breast reconstruction at an academic institution from 2004 to 2015. Patients were divided by use of hormone therapy at the time of surgery. Complication rates, including complete or partial flap loss and overall complications, were compared and analyzed using univariate and logistic regression models. RESULTS Among a total of 853 patients (1253 flaps), 193 patients (269 flaps) were receiving hormone therapy and 660 patients (984 flaps) were not. Patients on hormone therapy had higher rates of previous breast surgery, advanced cancer stage, chemoradiation before reconstruction, and delayed and unilateral reconstruction. There were no statistically significant differences between hormone therapy patients and nontherapy patients in complete flap loss (1.0 percent versus 1.1 percent) and partial flap loss (2.2 percent versus 1.5 percent). Hypertension and previous breast surgery were the only independent risk factors for minor complications (adjusted OR, 2.1; 95 percent CI, 1.3 to 3.6; p = 0.005; and adjusted OR, 1.8; 95 percent CI, 1.2 to 2.7; p = 0.009, respectively) and overall complications (adjusted OR, 2.2; 95 percent CI, 1.3 to 3.7; p = 0.004; and adjusted OR, 1.9; 95 percent CI, 1.3 to 3.0; p = 0.003, respectively). CONCLUSIONS Hormone therapy was not associated with a higher incidence of complete or partial flap loss or overall complications. The authors propose an individualized approach to the preoperative cessation of tamoxifen or aromatase inhibitors. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
Although many cancer survivors diagnosed with early-stage disease will outlive their cancer, they may continue to experience long-term and/or latent side effects due to cancer treatment. Many of these side effects are common and contribute to worse quality of life, morbidity, and mortality for cancer survivors. This article summarizes the treatment side effects for several of the most prevalent cancers in the United States.

Abstract
Background and Objectives: There are inconsistent results about the association between ischemic cerebrovascular disease and tamoxifen use in women with breast cancer. The study aimed to evaluate the association between the risk of ischemic cerebrovascular disease and tamoxifen use in older women with breast cancer in Taiwan. Methods: We designed a retrospective, nationwide, case-control study using the database of the Taiwan National Health Insurance Program. A total of 800 female subjects with breast cancer aged ≥65 years with the first episode of ischemic cerebrovascular disease from 2000 to 2011 were identified as the cases. Additionally, 2,876 female subjects with breast cancer aged ≥65 years without any type of cerebrovascular diseases were selected as the control subjects. The cases and the control subjects were matched with age and comorbidities. Ever use of tamoxifen was defined as a subject who had at least a prescription for tamoxifen before the index date. Never use of tamoxifen was defined as a subject who never had a prescription for tamoxifen before the index date. We used the multivariable logistic regression model to calculate the odds ratio (OR) and 95% confidence interval (CI) for ischemic cerebrovascular disease associated with tamoxifen use. Results: After adjusting for confounding variables, the adjusted OR of ischemic cerebrovascular disease was 2.5 for subjects with ever use of tamoxifen (95% CI 2.10, 2.97), compared with never use of tamoxifen. In addition, the adjusted OR of ischemic cerebrovascular disease was 1.15 (95% CI 1.10, 1.21) in subjects with ever use of tamoxifen as increase in use duration per 1 year. The adjusted OR of ischemic cerebrovascular disease was 2.54 (95% CI 2.03, 3.17) in subjects with ever use of tamoxifen as increase in dosage per 1 mg. Conclusions: Tamoxifen use is significantly associated with 2.5-fold increased odds of ischemic cerebrovascular disease among older women with breast cancer in Taiwan. There are duration-dependent and dose-dependent effects of tamoxifen use on the risk of ischemic cerebrovascular disease.

Abstract
INTRODUCTION Breast cancer is the most frequent cancer affecting women worldwide. In every setting, the majority of women are treated with an evergrowing arsenal of therapeutic agents that have greatly improved their outcomes. However, these therapies can also be associated with significant adverse events. Areas covered: This review aims to thoroughly describe the current state of the evidence regarding the potential cardiotoxicity of agents commonly used in the treatment of breast cancer. These include chemotherapeutic agents, anti-HER2 therapies and CDK4/6 and mTOR inhibitors. Furthermore, issues related to the risk stratification and monitoring tools are explored. Expert opinion: Anthracycline- and trastuzumab-related cardiac toxicities have been extensively studied. Substantial evidence is now available concerning additional anti-HER2 agents such as pertuzumab, T-DM1 and tyrosine kinase inhibitors; overall, the cardiotoxicity profile is reassuring. Cardiac events due to endocrine therapy are mostly ischemic and, in the context of prolonged therapy, need specific attention. Novel agents implicated in the treatment of hormone receptor-positive disease are potentially arrhythmogenic and the exact risk will need to be further refined. As for today, assessment of baseline risk factors prior to treatment initiation and cardiac imaging before and during treatment remains the optimal way to prevent cardiac dysfunction. Cardioprotective therapy in primary prevention is still a matter of debate.

Abstract
Certain cancer therapies, including radiation therapy and some types of chemotherapies, are associated with increased risk of cardiovascular disease (CVD) and events. Some of these effects such as those presented by anthracyclines, radiation therapy, cisplatin, as well as those presented by hormone therapy for breast cancer-usually taken for many years for some breast and prostate cancers-are long-lasting and associated with cardiovascular events risk more than 20 years after cancer treatment. Cardiovascular testing, diagnostic assessment of suspected cardiovascular symptomatology, as well as laboratory tests for CVD risk factors are imperative. The early recognition and treatment of CVD processes that arise in survivorship years is pivotal, with specific attention to some CVD processes with specific suggested treatment modalities. Preventive measures include adequate screening, the use of medications such as ACE inhibitors/angiotensin receptor blockers and/or beta blockers, statin therapy and aspirin in persons who warrant these medications, as well as therapeutic lifestyle modifications such as exercise/physical activity, weight loss and appropriate diet for a healthy lifestyle. Periodic follow-up with a good primary care physician who understands the risks associated with cancer therapy is important, and referral to onco-cardiology for further management of cardiovascular risk in these survivors is based on a patient's cardiovascular risk level and the type, amount and duration of cancer therapies received during the patient's lifetime.

Abstract
Background Although corticosteroids (CS) are used primarily in idiopathic retroperitoneal fibrosis (iRPF), tamoxifen (TMX) may be a suitable alternative. We compared outcome with CS or TMX monotherapy for first presentation in a large group of patients with iRPF disease. Methods Of all patients with iRPF disease who were seen at our tertiary care referral centre from February 1999 to December 2011, 118 patients were eligible for this retrospective study. Treatment success was defined as the composite of (i) amelioration of symptoms, (ii) computed tomography (CT)-documented mass regression and, if applicable, (iii) definitive removal of ureteral stent or nephrostomy tube. Recurrence was defined as recurrence of signs and symptoms and/or CT-documented mass increase after initial treatment success with primary treatment. Results Presenting signs and symptoms did not differ between patients treated with CS (n = 50) or TMX (n = 68). Time to amelioration of symptoms after treatment initiation was shorter in CS-treated patients [CS, 2.0 (0.8–3.8) weeks versus TMX, 4.0 (2.0–6.0) weeks; P < 0.01]. Short-term percentual decrease in acute-phase reactant levels (P < 0.001 for both erythrocyte sedimentation rate and C-reactive protein) and serum creatinine level (P < 0.01) following treatment initiation was greater in CS-treated patients compared with that in TMX-treated patients. Mass regression at first follow-up CT scan was observed more frequently in CS-treated patients (CS, 84.0% versus TMX, 68.3%; P = 0.05) with no difference in time interval from treatment initiation to first follow-up CT between groups [CS, 5 (2–7) months versus TMX, 4 (4–5) months; P = 0.34]. Definite treatment success was non-significantly higher in CS-treated patients (CS, 72.7% versus TMX, 58.3%; P = 0.15). In patients with initial treatment success with primary treatment, recurrence rate was lower in TMX-treated patients (CS, 62.5% versus TMX, 21.4%; P < 0.01). Conclusions CS are superior to TMX in treating iRPF disease. However, in patients with initial treatment success with primary treatment, recurrence rate was lower in TMX-treated patients.

Abstract
BACKGROUND Adjuvant tamoxifen reduces breast cancer recurrence risk and mortality; however, initiation and treatment persistence are poor for younger patients. We hypothesized that a unique set of factors, including fertility concerns, would contribute to the poor tamoxifen use among premenopausal patients. METHODS From 2007 to 2012, 515 premenopausal patients younger than age 45 years, with stage 0 to III hormone receptor-positive breast cancer, for whom tamoxifen was recommended, were identified. Clinical and pathologic tumor characteristics, treatment regimens, and fertility concerns were recorded. Clinical factors associated with tamoxifen noninitiation and discontinuation were identified using univariate and multivariable analysis. After the recommendation for tamoxifen, patient reasons for tamoxifen noninitiation or discontinuation were also documented. All statistical tests were two-sided. RESULTS Based on multivariable analysis, fertility concerns were statistically associated with both noninitiation (odds ratio = 5.04, 95% confidence interval (CI) = 2.29 to 11.07) and early discontinuation (hazard ratio = 1.78, 95% CI = 1.09 to 3.38) of tamoxifen. Other independent predictors of noninitiation included a diagnosis of ductal carcinoma in situ, declining radiation, and not receiving chemotherapy (stage I-III). Additionally, smoking and not receiving radiation therapy were statistically significant predictors of early withdrawal from therapy. Primary patient reasons for noninitiation and early discontinuation included concerns about side effects and fertility. CONCLUSION This study provided insight into factors associated with tamoxifen use for reproductive-aged breast cancer survivors, with a new focus on fertility. Fertility concerns negatively impacted tamoxifen initiation and continuation among premenopausal patients. Interventions to optimize treatment initiation and persistence for young cancer patients should include access to fertility preservation options.

Abstract
Breast cancer is the most commonly diagnosed malignancy in young women in the USA. Although breast cancer mortality has decreased overall, survival rates in young women remain lower than those in older women. Young women with breast cancer comprise a special population due to the aggressive biology of their tumors as well as their unique psychosocial concerns. Although general treatment principles are similar regardless of age, recent developments from research focused on younger women have provided new insights to guide treatment of this special population. This article will focus on these new developments in areas including endocrine therapy and fertility preservation as well as the unique treatment-related sequelae and psychosocial concerns among young women with breast cancer face.

Abstract
Estrogens act through interactions with estrogen receptors (ERs) to play diverse roles in various pathophysiological conditions. A number of synthetic selective estrogen receptor modulators (SERMs), such as tamoxifen and raloxifene, have been developed and used to treat ER-related diseases, including breast cancer and osteoporosis. Here, we identified a novel compound, bis(4-hydroxyphenyl)methanone-O-isopentyl oxime, designated NJK14013, as an ER agonist. NJK14013 activated ER-dependent transcription in a concentration-dependent manner, while suppressing androgen receptor-dependent transcriptional activity. It induced the activation-related phosphorylation of ER and enhanced the transcription of growth regulation by estrogen in breast cancer 1 (GREB1), further supporting its ER-stimulating activity. NJK14013 exerted anti-proliferative effects on various cancer cell lines, including an ER-negative breast cancer cell line, suggesting that it is capable of suppressing the growth of cancer cells independent of its ER-modulating activity. In addition, NJK14013 treatment resulted in significant apoptotic death of MCF7 and Ishikawa cancer cells, but did not induce apoptosis in non-cancer human umbilical vein endothelial cells. Collectively, our findings demonstrate that NJK14013 is a novel SERM that can activate ER-mediated transcription in MCF7 cells and suppress the proliferation of various cancer cells, including breast cancer cells and endometrial cancer cells. These results suggest that NJK14013 has potential as a novel SERM for anticancer or hormone-replacement therapy with reduced risk of carcinogenesis.

Abstract
BACKGROUND Estimates of the risk ratio of tamoxifen-associated venous thromboembolism (VTE) in breast cancer patients range from 2.4 to 7.1. The occurrence of thrombosis in patients with breast cancer complicates the clinical condition and causes a change of treatment. Our study was conducted in order to investigate the influence of patient-related risk factors for thrombosis development in breast cancer patients whose treatment included adjuvant tamoxifen. METHODS The prospective, single center, case control study included 150 breast cancer women, 50 whom developed venous thrombosis during adjuvant tamoxifen and 100 whom did not have thrombosis, as a control group. Patient-related risk factors such as: age, body mass index, previous VTE, varicose veins, concomitant diseases, the presence of prothrombotic mutations (FV Leiden, FII G20210A) and FVIII activity were evaluated in both groups. RESULTS In respect of prothrombotic mutations, the FV Leiden mutation was present in a higher number of women from the VTE group (10/50 vs 7/100; P=0.020). Additionally, FVIII activity was significantly higher in the VTE group; median (IQR), of 1.79 (0.69) vs 1.45 (0.55); P<0.001 and more women in this group (24/50 vs 34/100) had increased FVIII activity; P=0.020. In those women with FVIII>1.5IU/ml, who were carriers of prothrombotic mutations, an OR of 3.76 (CI 95% 1.276-11.096; P=0.016) was obtained for VTE. CONCLUSION The results of our study showed that the factor V Leiden mutation and high FVIII are associated with an increased risk of VTE in women with breast cancer during adjuvant tamoxifen.

Abstract
Tamoxifen could increase the risk for venous thromboembolic complications. Clinicians should concern the possibility of thrombotic event with tamoxifen. In high-risk patients, new aromatase inhibitors might be considered alternative.
Introduction Tamoxifen reduces breast cancer risk, but can cause thromboembolic complications. Cerebral venous thrombosis is a rare form of stroke in which blood clots occlude the dural sinus or cerebral veins. Presentation of case A 46-year old female presented with a severe headache and nausea of subacute onset. She had undergone masectomy for breast cancer 20 months ago and had been taking tamoxifen. Brain CT and MRI confirmed cerebral venous infarction and venous thrombosis in the superior sagittal sinus and straight sinus. She had elevated D-dimer level, decreased levels of protein S activity and antithrombin III. Doppler ultrasound revealed concurrent deep vein thrombosis in her right leg. There was no evidence of breast cancer recurrence. With oral anticoagulation, she discharged without neurological complications. The abnormal laboratory findings of coagulopathy returned to normal after discontinuation of tamoxifen. Discussion Considering the abnormal findings in the workup of coagulopathy and no other risk factor for venous thrombosis, this thromboembolic complication can be attributed to the coagulopathy with use of tamoxifen. Conclusion Clinicians should warn about the possibility of thromboembolic complications with tamoxifen.

Abstract
OBJECTIVE Vaginal estrogen therapy at the lowest effective dose is generally recommended for the treatment of vulvar and vaginal atrophy (VVA), but not all women are candidates. Selective estrogen receptor modulators (SERMs) aim to elicit specific positive effects on targeted tissues with neutral or minimal negative effects on other tissues. This review compares the vaginal effects of currently available and investigational SERMs. METHODS Relevant English-language articles published between 1980 and 2012 were identified through the PubMed database (search string "[Selective Estrogen Receptor Modulator OR SERM] AND [Vulvar OR Vaginal] AND Atrophy"), article reference lists, and EMBASE searches for individual SERMs. Both authors reviewed all articles, which formed the basis of this narrative literature review. RESULTS Activity profiles of SERMs in various tissues are distinct. Tamoxifen and arzoxifene have no specific positive vaginal effects but have reported variable or adverse gynecologic effects. Raloxifene does not improve VVA but can be used safely in combination with vaginal estrogen. Bazedoxifene has no demonstrated efficacy for VVA but, in combination with oral conjugated equine estrogens, improves the signs and symptoms of VVA. SERMs with positive vaginal effects (such as improvement in the vaginal maturation index, reduced vaginal pH, and improvement in the signs and symptoms of VVA) on postmenopausal symptomatic women include lasofoxifene (clinical development on hold) and ospemifene, which was recently approved for the treatment of VVA-related dyspareunia, with a class effect warning of potential venous thrombosis risk. CONCLUSIONS SERMs that specifically target the pathophysiology underlying VVA may provide an alternative to vaginal or systemic estrogen therapy.

Abstract
Tamoxifen is an effective endocrine treatment for early breast cancer (EBC) but increases the risk of venous thromboembolism. Whether Asian EBC patients (pts) bear the same risk when treated with adjuvant tamoxifen is uncertain. EBC pts diagnosed between 2004 and 2009 were selected from a population database in Taiwan. The pts were followed up from the index date to December 31, 2011 to collect events of deep vein thrombosis (DVT) and pulmonary embolism (PE). Cumulative incidence rates and hazard ratios (HRs) were used to compare the risk between pts treated with and without tamoxifen. In addition, comorbidities were included in an adjusted model of the risk of DVT and PE. A total of 28,029 EBC pts, including 17,843 (63.8 %) in the tamoxifen group and 10,155 (36.2 %) in the nontamoxifen group, were analyzed. The 7-year cumulative incidence rates for DVT and PE were 2.58 and 0.32 % in the tamoxifen group and 2.51 and 0.32 % in the nontamoxifen group (P = 0.92 for DVT, P = 0. 65 for PE), respectively. The HR for the nonadjusted and adjusted models showed no differences in DVT and PE risks between the tamoxifen and nontamoxifen groups. The uterine cancer risk was significantly increased in the pts receiving tamoxifen (adjusted HR = 2.79, P < 0.001), suggesting tamoxifen compliance. The risks of developing DVT and PE are not increased in Asian EBC pts receiving adjuvant tamoxifen. Ethnicity differences should be considered when discussing optimal endocrine treatments with EBC pts.

Abstract
Selective estrogen receptor modulators (SERMs) are synthetic non-steroidal agents which have varying estrogen agonist and antagonist activities in different tissues, most likely due to the receptor conformation changes associated with that SERM's binding and the subsequent effect on transcription. Clinical trials aim to differentiate amongst SERMs on selected target tissues for use in postmenopausal women including effects on breast, bone, cardiovascular venous thrombosis risk, endometrium, vagina, vasomotor symptoms, and brain. This paper describes differences in clinical effects on selected target tissues of SERMs that are approved, discontinued or in development. FDA approved SERMs include tamoxifen and toremifene used for prevention and treatment of breast cancer, raloxifene approved for prevention and treatment of osteoporosis and prevention of invasive breast cancer, and ospemifene approved for treatment of dyspareunia from menopausal vaginal atrophy. The FDA approved first tissue selective estrogen complex (TSEC) a pairing of conjugated equine estrogens with the SERM, bazedoxifene. This pairing reduces the risk of endometrial hyperplasia that can occur with the estrogenic component of the TSEC without the need for a progestogen in women with a uterus. It also allows for the estrogenic benefits on relief of hot flashes and prevention of bone loss without stimulating the breast or the endometrium. In clinical practice, the tissue-selective actions of SERMs, alone or paired with estrogens, allow for individualization in meeting the treatment needs of postmenopausal women by providing targeted tissue effects. This article is part of a Special Issue entitled 'Menopause'.

Abstract
Purpose To update the 2009 American Society of Clinical Oncology guideline on pharmacologic interventions for breast cancer (BC) risk reduction. Methods A systematic review of randomized controlled trials and meta-analyses published from June 2007 through June 2012 was completed using MEDLINE and Cochrane Collaboration Library. Primary outcome of interest was BC incidence (invasive and noninvasive). Secondary outcomes included BC mortality, adverse events, and net health benefits. Guideline recommendations were revised based on an Update Committee's review of the literature. Results Nineteen articles met the selection criteria. Six chemoprevention agents were identified: tamoxifen, raloxifene, arzoxifene, lasofoxifene, exemestane, and anastrozole. Recommendations In women at increased risk of BC age ≥ 35 years, tamoxifen (20 mg per day for 5 years) should be discussed as an option to reduce the risk of estrogen receptor (ER) –positive BC. In postmenopausal women, raloxifene (60 mg per day for 5 years) and exemestane (25 mg per day for 5 years) should also be discussed as options for BC risk reduction. Those at increased BC risk are defined as individuals with a 5-year projected absolute risk of BC ≥ 1.66% (based on the National Cancer Institute BC Risk Assessment Tool or an equivalent measure) or women diagnosed with lobular carcinoma in situ. Use of other selective ER modulators or other aromatase inhibitors to lower BC risk is not recommended outside of a clinical trial. Health care providers are encouraged to discuss the option of chemoprevention among women at increased BC risk. The discussion should include the specific risks and benefits associated with each chemopreventive agent.

Abstract
BACKGROUND Symptomatic pulmonary embolism constitutes a significant risk following abdominal flap breast reconstruction. Reported rates vary from 0 to 6 percent. The authors assessed risk factors associated with symptomatic pulmonary embolism and constructed a prediction model to identify high-risk patients. METHODS Patients undergoing deep inferior epigastric perforator or transverse rectus abdominis musculocutaneous flap breast reconstructions at two academic centers from January of 2005 through January of 2011 were included. Thromboprophylaxis measures included early ambulation, low-molecular-weight heparin, elastic stockings, A-V Impulse System foot pumps, and pneumatic stockings. Risk factors for symptomatic pulmonary embolism were analyzed and weights were assigned to these risk factors. Sensitivity and specificity were maximized using receiver operating characteristic curves. RESULTS Of 430 consecutive patients, symptomatic pulmonary embolism occurred in 17 cases (4.0 percent). Two independent predictors for symptomatic pulmonary embolism were found, body mass index higher than 25, additionally higher than 28, and the BRCA gene mutation. Operation duration and bilaterality of reconstructions were dependent on the BRCA mutation and both indirect predictors for symptomatic pulmonary embolism. Optimization of sensitivity and specificity resulted in a prediction model. No significant differences in efficacy were found between the different thromboprophylaxis measures. CONCLUSIONS The rate of symptomatic pulmonary embolism was 4.0 percent, despite standard thromboprophylaxis. Body mass index and BRCA were significant predictors for symptomatic pulmonary embolism. The authors integrated these factors into a prediction model, which provides a useful tool for identification of high-risk patients. This latter category may benefit from a more aggressive thromboprophylaxis approach. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Abstract
BACKGROUND Tamoxifen may be a viable treatment option for idiopathic retroperitoneal fibrosis (iRPF) but data are limited and its long-term safety and efficacy is unclear. We describe the long-term course and outcomes in a large group of patients with iRPF treated with tamoxifen monotherapy. METHODS This is a single-center prospective, observational study of 55 patients with iRPF treated with tamoxifen for 2years from April 1998 through April 2011. Measurements included clinical improvement, laboratory parameters and follow-up computed tomographic (CT) scanning. Treatment success was the composite endpoint of clinical improvement, mass regression and definite resolution of ureteral obstruction. RESULTS Forty-seven (85%) patients reported substantial resolution of symptoms after median treatment duration of 3.0weeks (IQR 1.4-4.8weeks). Repeated CT scanning showed mass regression in 39 (71%) patients at 4months and 47 (85%) patients at 8months of follow-up, respectively. Nineteen (34.5%) patients did not meet the composite endpoint of treatment success, 56% of whom responded satisfactorily to second-line immunosuppressive treatment. Recurrence-free survival in patients with treatment success after post-treatment follow-up of 21months (IQR 9.0-35.0months) was 68%. Tamoxifen was well tolerated. Pulmonary embolism occurred in 2 patients receiving tamoxifen and in one patient receiving second-line treatment. CONCLUSION Tamoxifen is a safe and viable therapeutic option in the treatment of iRPF.

Abstract
Dipyridamole (DPM) is widely used to prevent strokes and vascular thrombosis. Combination therapy of DPM and antimetabolites has shown synergistic anticancer activity. This study investigated the chemopreventive effects of DPM in the mouse mammary tumor virus promoter-driven polyoma middle T oncoprotein metastatic breast cancer model. We also investigated the effects of DPM on gene and miRNA expression. Chemopreventive activity was assessed by comparing the time to onset of palpable lesions, primary tumor growth kinetics, and the number of lung metastases in transgenic mice treated with DPM or vehicle. Gene expression and miRNA expression profiles of mammary tumor tissues were then analyzed using the Affymetrix GeneChip or miRNA 2.0 arrays. Real-time quantitative PCR was used to confirm changes in gene expression. Treatment with DPM beginning at the age of 4 weeks delayed the onset of palpable lesions, delayed tumor progression, and suppressed lung metastasis. Microarray gene expression analysis identified 253 genes differentially expressed between DPM-treated and control mammary tumors. miRNA expression analysis revealed that 53 miRNAs were altered by DPM treatment. The results indicate that DPM has chemoprevention activity against breast cancer tumorigenesis and metastasis in mice. The array analyses provide insights into potential mechanisms of DPM's chemopreventive effects, involving upregulation of several genes and miRNAs known to suppress cancer growth and/or metastasis and downregulation of genes known to promote cancer. Some of these genes have not been previously studied in breast cancer and may serve as novel molecular targets for breast cancer chemoprevention.

Abstract
We reported a rare case of Budd-Chiari syndrome (BCS) associated with tamoxifen use, which was later complicated by heparin-induced thrombocytopenia and thrombosis (HITT). The patient was a 44 year-old woman with a medical history of lobular carcinoma in situ, who had been on tamoxifen for 2 years, presented with abdominal pain and distention. Imaging studies followed by a liver biopsy confirmed the diagnosis of BCS. On extensive work-up, the patient was found to have an unclassified myeloproliferative disorder with positive JAK-2 V617 mutation. After discontinuing tamoxifen, the patient was started on intravenous heparin. However, later in the course, she developed HITT. Myeloproliferative disorder, in conjunction with tamoxifen, predisposed the patient to be highly thrombophilic resulting in BCS. HITT was found to be relatively common in BCS. Anticoagulation and blood count need to be carefully monitored, and the possibility of HITT emergence in these patients should always be kept in mind.
