The Risk of Cancer-Associated and Radiotherapy-Associated Cardiovascular Diseases among Patients with Breast Cancer. Clin Breast Cancer 2024; 24:131-141.e3. [PMID: 38052665 DOI: 10.1016/j.clbc.2023.11.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 10/17/2023] [Accepted: 11/10/2023] [Indexed: 12/07/2023]
Abstract
BACKGROUND The cardio-related issues should be emphasized as the survival rates of breast cancer increased. We investigated the risk of coronary artery disease (CAD) and stroke due to breast cancer or radiotherapy. METHODS In this retrospective cohort study, breast cancer patients diagnosed between 2007 and 2016 were recruited from Taiwan Cancer Registry Database and were followed until the end of 2018 by linking with the Taiwan National Health Insurance Database. The general population was randomly selected from the whole population in 2007. Standardized incidence ratios (SIR) were calculated to compare the risk of CAD and stroke between patients and the general population. Within the cohort, we included the patients diagnosed between 2011 and 2016. Cox proportional hazards model and subdistribution hazard function were used to investigate the associations of radiotherapy with the risk of CAD and stroke. RESULTS Overall SIR of CAD was 0.82 (95% confidence interval [CI]: 0.78-0.86), while were 1.43 and 1.08 (95% CI: 1.30-1.55 and 1.00-1.16) 1 and 2 years after diagnosis, respectively. Overall SIR of stroke was 0.63 (95% CI: 0.60-0.67), the results were similar after considering the time since diagnosis. The adjusted hazard ratios (HR) for the associations of radiotherapy with CAD and stroke risk were 0.91 (95% [CI] = 0.76-1.09) and 0.84 (95% CI = 0.68-1.04), respectively. The results were similar by using subdistribution hazard function. CONCLUSIONS The risk of CAD was higher within the first 2 years of breast cancer diagnosis. We found no association between radiotherapy and the risk of CAD and stroke.

Abstract
BACKGROUND Cancer survivors are at increased risk of pain due to their either cancer and/or treatments. Substances like alcohol may be used to self-medicate cancer pain; however, these substances pose their own health risks that may be more pronounced for cancer survivors. METHODS We used cross-sectional data from the Behavioral Risk Factor Surveillance System (BRFSS) 2012-2019 to quantify the association between cancer pain and alcohol use. We used negative binomial regression, with interaction terms added to examine variations across age, sex, and race. We also examined whether alcohol use relates to cancer pain control status. RESULTS Cancer survivors with cancer pain were more likely to be younger, female, Black, and to have been diagnosed with breast cancer. Cancer pain was associated with lower alcohol consumption (incidence rate ratio (IRR): 0.88, confidence interval (CI): 0.77, 0.99). This association was primarily among people 65 and older, women, and white and Hispanic people. Cancer pain control status was not related to alcohol use. CONCLUSIONS Lower alcohol use among cancer survivors with pain has many possible explanations, including several alternative pain management strategies or a decrease in social engagement. Our findings of racial and gender disparities in cancer pain are consistent with the broader evidence on disparities in pain. IMPLICATIONS FOR CANCER SURVIVORS Cancer pain management for marginalized groups should be improved. Healthcare providers should screen cancer survivors for both pain and substance use, to prevent unhealthy self-medication behaviors.

Abstract
The increasing burden on human malignant diseases became a major concern for healthcare practitioners, that must deal with tumor relapse and the inability to efficiently treat metastasis, in addition to side effects. Throughout the decades, many therapeutic strategies have been employed to improve the clinical outcomes of cancer patients and great efforts have been made to develop more efficient and targeted medicines. The malignant cell is characterized by genetic and epigenetic modifications, therefore targeting those specific drivers of carcinogenesis is highly desirable. Among the genome editing technologies, CRISPR/Cas9 stood as a promising candidate for cancer treatment alternatives, due to its low complexity design. First described as a defense mechanism of bacteria against invading foreign DNA, later it was shown that CRISPR components can be engineered to target specific DNA sequences in a test tube, a discovery that was awarded later with the Nobel Prize in chemistry for its rapid expansion as a reliable genome editing tool in many fields of research, including medicine. The present paper aims of describing CRISPR/Cas9 potential targets for malignant disorders, and the approaches used for achieving this goal. Aside from preclinical studies, we also present the clinical trials that use CRISPR-based technology for therapeutic purposes of cancer. Finally, a summary of the presented studies adds a more focused view of the therapeutic value CRISPR/Cas9 holds and the associated shortcomings.

A Descriptive Study of the Types and Survival Patterns of Saudi Patients with Multiple Primary Solid Malignancies: A 30-Year Tertiary Care Center Experience. Curr Oncol 2022; 29:4941-4955. [PMID: 35877253 PMCID: PMC9315520 DOI: 10.3390/curroncol29070393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 06/30/2022] [Accepted: 07/07/2022] [Indexed: 11/16/2022] Open
Abstract
Background and Objective: Cancer survival has improved significantly, which reflects the achievements in screening, diagnosis, and treatment. As a consequence, multiple primary malignancies are diagnosed more frequently, with an incidence ranging from 0.52–11.7%. The types of malignancy that coexist and survival patterns vary notably in different countries and geographical areas. Due to the limited literature in Saudi Arabia, a baseline of prevalent malignancy combinations and their survival patterns would support early detection and disease management. Method: This was a retrospective descriptive study conducted from 1993–2022 at King Abdulaziz Medical City, Department of Medical Oncology, Riyadh, Saudi Arabia. Patients with at least two biopsy-proven solid malignancies were included. Patients with hematological malignancies, missing data, or an uncertain or indecisive pathology report were excluded. Result: In total, 321 patients were analyzed. More than half (57.3%) of the patients were female. A third (33%) of the cases were synchronous, and 67% were metachronous. The most frequent site of the first primary malignancy was breast cancer, followed by colorectal, skin, and thyroid cancers. The most frequent site of the second primary malignancy was colorectal cancer, followed by thyroid, breast, and liver cancers. Only 4% of the cases had a third primary malignancy, with colorectal and appendiceal cancers being the most frequent. The most frequently observed histopathology in the synchronous and metachronous malignancies was adenocarcinoma. Breast–colorectal, breast–thyroid, and kidney–colorectal were the most frequently observed malignancy combinations. Conclusion: The current study offers a baseline of multiple primary malignancies in Saudi Arabia and provides supporting evidence that the pattern of multiple primary malignancies varies among different countries and ethnicities. The possibility of developing another primary malignancy should be considered when treating and monitoring cancer patients.

Abstract
INTRODUCTION To compare the risk of developing lung cancer between patients with breast cancer and the general population and explore the risk factors for the development of primary lung cancer after treatment for breast cancer. METHODS The PubMed, EMBASE, and Web of Science databases were searched from the establishment date to October 11, 2020. Two separate meta-analyses were performed: one focused on studies reporting the risk of subsequent lung cancer after breast cancer and one focused on studies exploring the risk factors for subsequent lung cancer in patients with breast cancer. The standardized incidence ratios with 95% confidence intervals were combined to compare the risk of developing lung cancer between patients with breast cancer and the general population. The relative risks (RRs) or ORs with 95% confidence intervals were combined to assess the association of clinicopathological parameters with the risk of developing lung cancer after breast cancer. All statistical analyses were conducted by STATA 12.0. RESULTS A total of 15 studies involving 1,161,979 patients were eventually included in the first meta-analysis, and the pooled results indicated that female patients with breast cancer revealed a significantly higher risk of developing subsequent lung cancer (standardized incidence ratio = 1.25, p < 0.001). In addition, a total of 22 articles involving 3,090,620 patients were included in the second meta-analysis. The pooled results indicated that smoking (OR = 9.73, p < 0.001) and radiotherapy (RR = 1.40, p < 0.001) were risk factors for developing subsequent lung cancer in patients with breast cancer, and chemotherapy (RR = 0.69, p = 0.002), positive estrogen receptor status (RR = 0.93, p = 0.014) and positive progesterone receptor status (RR = 0.86, p < 0.001) were protective factors. Meanwhile, subgroup analysis based on the relative position of the breast and lung cancers (ipsilateral versus contralateral) was conducted, which indicated that radiotherapy only increased the risk of ipsilateral lung cancer in patients with breast cancer (RR = 1.27, p = 0.001). CONCLUSIONS Patients with breast cancer are more likely to develop lung cancer than the general population, and the risk of developing primary lung cancer after breast cancer is affected by smoking, radiotherapy, chemotherapy, estrogen receptor status and progesterone receptor status.

Abstract
IMPORTANCE To promptly recognize and manage cardiovascular (CV) risk factors before, during, and after cancer treatment, decreasing the risk of cancer therapy-related cardiac dysfunction is crucial. After recent advances in breast cancer treatment, mortality rates from cancer have decreased, and the prevalence of survivors with a potentially higher CV disease risk has increased. Cardiovascular risks might be associated with the multimodal approach, including systemic therapies and breast radiotherapy (RT). OBSERVATIONS The heart disease risk seems to be higher in patients with tumors in the left breast, when other classic CV risk factors are present, and when adjunctive anthracycline-based chemotherapy is administered, suggesting a synergistic association. Respiratory control as well as modern RT techniques and their possible further refinement may decrease the prevalence and severity of radiation-induced heart disease. Several pharmacological cardioprevention strategies for decreasing cardiac toxic effects have been identified in several guidelines. However, further research is needed to ascertain the feasibility of these strategies in routine practice. CONCLUSIONS AND RELEVANCE This review found that evidence-based recommendations are lacking on the modalities for and intensity of heart disease screening, surveillance of patients after RT, and treatment of these patients. A multidisciplinary and multimodal approach is crucial to guide optimal management.

Abstract
OBJECTIVE Studies examining radiation-induced heart toxicity in breast cancer patients are inconclusive. The aim of this study was to prospectively and quantitatively asses myocardial blood flow (MBF) with, for the first time, 15O-H2O PET/CT as a marker of heart damage in irradiated breast cancer patients. METHODS 15 breast cancer patients receiving intact breast or chest wall irradiation were included in the analysis (six with right-sided and nine with left-sided breast cancer). They underwent 15O-H2O PET/CT before radiotherapy (RT) and 2 and 8 months after RT. MBF was quantitatively assessed at rest and under stress conditions in 17 heart segments distinguished according to the American Ultrasound Association classification. Regional MBF values were derived in each of the coronary artery territories. RESULTS MBF decreased in 53% and increased in 33% of cases 2 months after RT in both left-sided and right-sided breast cancer patients. Stress testing was more sensitive than at-rest testing, demonstrating decreased perfusion in the segments supplied by the left anterior descending coronary artery (LAD) [5.41 ± 1.74 vs 4.52 ± 1.82 ml (g*min)-1; p = 0.018], which persisted at 6 months [5.41 ± 1.74 vs 4.40 ± 1.38 ml (g*min)-1; p = 0.032] and a decrease in global heart perfusion [5.14 ± 1.49 vs 4.46 ± 1.73 ml (g*min)-1; p = 0.036]. A minimal radiation dose applied to the LAD correlated with MBF changes observed 2 months after RT (r = -0.57; p = 0.032). Radiological findings were not correlated with clinical symptoms of heart toxicity. CONCLUSION 15O-H2O PET/CT is safe and effective for the early detection and quantitative analysis of subclinical post-RT changes in heart perfusion in breast cancer patients. The LV segments supplied by the LAD are the main site of MBF changes. A minimum radiation dose deposited in the LAD may be a predictor of radiation-induced heart toxicity. Advances in knowledge: This is the first time that 15O-H2O PET/CT has been used to assess MBF after RT and the first granular description of the distribution of blood flow changes after breast cancer RT.

Abstract
Background Radiotherapy for breast cancer often involves some incidental exposure of the heart to ionizing radiation. The effect of this exposure on the subsequent risk of heart disease is uncertain. We performed a meta‐analysis to investigate the link between radiotherapy and long‐term cardiovascular morbidity and mortality in patients with breast cancer. Methods and Results We performed a literature search using MEDLINE (January 1966 to January 2015) and EMBASE (January 1980 to January 2015) with no restrictions. Studies that reported relative risk (RR) estimates with 95%CIs for the associations of interest were included. Pooled effect estimates were obtained by using random‐effects meta‐analysis. Thirty‐nine studies involving 1 191 371 participants were identified. Patients who received left‐sided radiotherapy, as compared with those receiving right‐sided radiotherapy, experienced increased risks of developing coronary heart disease (RR 1.29, 95%CI 1.13‐1.48), cardiac death (RR 1.22, 95%CI 1.08‐1.37) and death from any cause (RR 1.05, 95%CI 1.01‐1.10). In a comparison of patients with radiotherapy and without radiotherapy, the RRs were 1.30 (95%CI 1.13‐1.49) for coronary heart disease and 1.38 (95%CI 1.18‐1.62) for cardiac mortality. Radiotherapy for breast cancer was associated with an absolute risk increase of 76.4 (95%CI 36.8‐130.5) cases of coronary heart disease and 125.5 (95%CI 98.8‐157.9) cases of cardiac death per 100 000 person‐years. The risk started to increase within the first decade for coronary heart disease and from the second decade for cardiac mortality. Conclusions Exposure of the heart to ionizing radiation during radiotherapy for breast cancer increases the subsequent risk of coronary heart disease and cardiac mortality.

Abstract
BACKGROUND This review update has been managed by both the Childhood Cancer and Cochrane Gynaecological, Neuro-oncology and Orphan Cancer Groups.The use of anthracycline chemotherapy is limited by the occurrence of cardiotoxicity. To prevent this cardiotoxicity, different anthracycline dosage schedules have been studied. OBJECTIVES To determine the occurrence of cardiotoxicity with the use of different anthracycline dosage schedules (that is peak doses and infusion durations) in people with cancer. SEARCH METHODS We searched the databases of the Cochrane Register of Controlled Trials (CENTRAL) (the Cochrane Library, Issue 11, 2015), MEDLINE (1966 to December 2015), and EMBASE (1980 to December 2015). We also searched reference lists of relevant articles, conference proceedings, experts in the field, and ongoing trials databases. SELECTION CRITERIA Randomised controlled trials (RCTs) in which different anthracycline dosage schedules were compared in people with cancer (children and adults). DATA COLLECTION AND ANALYSIS Two review authors independently performed the study selection, the 'Risk of bias' assessment, and data extraction. We performed analyses according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS We identified 11 studies: 7 evaluated different infusion durations (803 participants), and 4 evaluated different peak doses (5280 participants). Seven studies were RCTs addressing different anthracycline infusion durations; we identified long-term follow-up data for one of the trials in this update. The meta-analysis showed a statistically significant lower rate of clinical heart failure with an infusion duration of six hours or longer as compared to a shorter infusion duration (risk ratio (RR) 0.27; 95% confidence interval 0.09 to 0.81; 5 studies; 557 participants). The majority of participants included in these studies were adults with different solid tumours. For different anthracycline peak doses, we identified two RCTs addressing a doxorubicin peak dose of less than 60 mg/m(2) versus 60 mg/m(2) or more, one RCT addressing a liposomal doxorubicin peak dose of 25 mg/m(2) versus 50 mg/m(2), and one RCT addressing an epirubicin peak dose of 83 mg/m(2) versus 110 mg/m(2). A significant difference in the occurrence of clinical heart failure was identified in none of the studies. The participants included in these studies were adults with different solid tumours. High or unclear 'Risk of bias' issues were present in all studies. AUTHORS' CONCLUSIONS An anthracycline infusion duration of six hours or longer reduces the risk of clinical heart failure, and it seems to reduce the risk of subclinical cardiac damage. Since there is only a small amount of data for children and data obtained in adults cannot be extrapolated to children, different anthracycline infusion durations should be evaluated further in children.We identified no significant difference in the occurrence of clinical heart failure in participants treated with a doxorubicin peak dose of less than 60 mg/m(2) or 60 mg/m(2) or more. Only one RCT was available for the other identified peak doses, so we can make no definitive conclusions about the occurrence of cardiotoxicity. More high-quality research is needed, both in children and adults and in leukaemias and solid tumours.

Abstract
This study aims to investigate whether patients with breast cancer and a history of cardiovascular diseases (CADs) are at an increased incidence of acute coronary syndrome (ACS) after receiving radiation therapy (RT). In Taiwan, 5828 patients who had a history of CAD were newly diagnosed of breast cancer and received mastectomy between 1999 and 2009. Among these patients, 1851 also received RT. The study cohort was prospectively followed to the end of 2010 for estimating the incidence of ACS in association with exposure to RT. A Cox proportional hazard model that was adjusted for covariates was used to estimate the hazard ratio (HR) of ACS. Over the study period, the incident rates of ACS for RT and control patients were estimated at 1.51 and 1.77 per 100 person-years, respectively. Covariate-adjusted regression analysis indicated that the hazard of ACS significantly increased in RT patients at an adjusted HR of 1.48 [95% confidence interval (CI) 1.18-1.87]. Both hypertension and diabetes significantly increased the hazard of ACS in this patient cohort, with adjusted HRs of 3.31 (95% CI 1.94-5.66) and 1.50 (95% CI 1.19-1.89), respectively. This 12-year follow-up study suggested excess of ACS events in association with RT exposure in patients with breast cancer who had a higher cardiovascular risk. In consideration of the benefit associated with RT, intensive cardiac care should be given to patients with breast cancer and high cardiovascular risk.

Abstract
Nanotechnology is becoming an important field of biomedical and clinical research and the application of nanoparticles in disease may offer promising advances in treatment of many diseases, especially cancer. Malignant melanoma is one of the most aggressive forms of cancer and its incidence is rapidly increasing. Redox-active cerium oxide nanoparticles (CNP) are known to exhibit significant antitumor activity in cells derived from human skin tumors in vitro and in vivo, whereas CNP is nontoxic and beyond that even protective (antioxidative) in normal, healthy cells of the skin. As the application of conventional chemotherapeutics is associated with harmful side effects on healthy cells and tissues, the clinical use is restricted. In this study, we addressed the question of whether CNP supplement a classical chemotherapy, thereby enhancing its efficiency without additional damage to normal cells. The anthracycline doxorubicin, one of the most effective cancer drugs, was chosen as reference for a classical chemotherapeutic agent in this study. Herein, we show that CNP enhance the antitumor activity of doxorubicin in human melanoma cells. Synergistic effects on cytotoxicity, reactive oxygen species generation, and oxidative damage in tumor cells were observed after co-incubation. In contrast to doxorubicin, CNP do not cause DNA damage and even protect human dermal fibroblasts from doxorubicin-induced cytotoxicity. A combination of classical chemotherapeutics with nongenotoxic but antitumor active CNP may provide a new strategy against cancer by improving therapeutic outcome and benefit for patients.

Abstract
BACKGROUND Women are more likely to develop cancer in the left breast than the right. Such laterality may influence subsequent management, especially in elderly patients with heart disease who may require radiation therapy. The purpose of this study was to explore possible factors for such cancer laterality. METHODS In this work, clinical data for consecutive patients with histologically confirmed breast cancer were reviewed, with emphasis on clinical presentation and family history. RESULTS Between 2005 and 2012, 687 patients with breast cancer were seen. Two women with incomplete data and eleven men were excluded. In total, 343 (50.9%) patients presented with left breast cancer, 311 (46.1%) with right breast cancer, and 20 (3.0%) with simultaneous bilateral malignancy. There were no significant differences between the three groups, especially in regards to clinical presentation and tumor characteristics. A total of 622 (92.3%) patients had unilateral primary, 20 (3.0%) had simultaneous bilateral, and 32 (4.7%) had metachronous primary breast cancer with subsequent contralateral breast cancer after 7.5-236 months. The worst 10-year survival was for bilateral simultaneous (18%) compared with unilateral (28%) and metachronous primaries (90%). There were no differences in survival in relation to breast cancer laterality, handedness, and presence or absence of a family history of cancer. There were significant similarities between patients and first-degree relatives in regards to breast cancer laterality, namely same breast (30/66, 45.5%), opposite breast (9/66, 13.6%), and bilateral cancer (27/66, 40.9, P=0.01163). This was more evident among patients and their sisters (17/32, 53.1%) or mothers (11/27, 40.7%, P=0.0689). There were also close similarities in relation to age at initial diagnosis of cancer for patients and their first-degree relatives for age differences of ≤5 years (48/166, 28.9%), 6-10 years (34/166, 20.5%), and >11 years (84/166, 50.6%, P=0.12065). CONCLUSION High similarities between patients and their first-degree relatives in regards to cancer laterality and possibly age at initial diagnosis of cancer may suggest an underlying inherited genetic predisposition.

Abstract
For women who opt for mastectomy as primary surgery in breast cancer, indications for adjuvant radiotherapy are also being redefined in light of evidence demonstrating that postmastectomy radiotherapy (PMRT), when given in conjunction with systemic therapy, improves, not only locoregional control, but also survival. However, in certain settings, particularly in patients wih intermediate-risk disease, and in some patients treated with neoadjuvant chemotherapy, the role of PMRT remains controversial. Here, the authors review modern data pertaining to the benefits and risks of PMRT and discuss controversies related to the indications for PMRT, focusing on patients with T1-2 breast cancer with 0-3 positive nodes and patients treated with neoadjuvant chemotherapy. They also summarize key issues related to the integration of PMRT with other treatment modalities.

Abstract
OBJECTIVE Cardiac irradiation during left-sided breast radiotherapy may lead to deleterious cardiac side effects. Using image guided radiotherapy, it is possible to exclude the heart from treatment fields and monitor reproducibility of virtual simulation (VS) fields at treatment delivery using electronic portal imaging (EPI). Retrospectively, we evaluate the incidence of cardiac irradiation at VS and subsequent unintended cardiac irradiation during treatment. METHODS Patients receiving left-sided radiotherapy to the breast or chest wall, treated with a glancing photon field technique during a four-month period, were included. VS images and EPIs during radiotherapy delivery were visually assessed. The presence of any portion of the heart within the treatment field at VS or during treatment was recorded. Central lung distance and maximum heart distance were recorded. RESULTS Of 128 patients, 45 (35.1%) had any portion of the heart within the planned treatment field. Of these, inclusion of the heart was clinically unavoidable in 25 (55.6%). Of those with no heart included in the treatment fields at VS, 41 (49.4%) had presence of the heart as assessed on EPI during treatment. CONCLUSION Unintended cardiac irradiation during left-sided breast radiotherapy treatment occurs in a sizeable proportion of patients. ADVANCES IN KNOWLEDGE Despite the use of three-dimensional computed tomography simulation and cardiac shielding, sizeable proportions of patients receiving left-sided breast cancer radiotherapy have unintended cardiac irradiation.

Abstract
PURPOSE The risk of secondary lung malignancy (SLM) is a significant concern for women treated with whole-breast radiation therapy after breast-conserving surgery for early-stage breast cancer. In this study, a biologically based secondary malignancy model was used to quantify the risk of secondary lung malignancies (SLMs) associated with several common methods of delivering whole-breast radiation therapy (RT). METHODS AND MATERIALS Both supine and prone computed tomography simulations of 15 women with early breast cancer were used to generate standard fractionated and hypofractionated whole-breast RT treatment plans for each patient. Dose-volume histograms (DVHs) of the ipsilateral breast and lung were calculated for each patient on each plan. A model of spontaneous and radiation-induced carcinogenesis was used to determine the relative risks of SLMs for the different treatment techniques. RESULTS A higher risk of SLMs was predicted for supine breast irradiation when compared with prone breast irradiation for both the standard fractionation and hypofractionation schedules (relative risk [RR] = 2.59, 95% confidence interval (CI) = 2.30-2.88, and RR = 2.68, 95% CI = 2.39-2.98, respectively). No difference in risk of SLMs was noted between standard fractionation and hypofractionation schedules in either the supine position (RR = 1.05, 95% CI = 0.97-1.14) or the prone position (RR = 1.01, 95% CI = 0.88-1.15). CONCLUSIONS Compared with supine whole-breast irradiation, prone breast irradiation is associated with a significantly lower predicted risk of secondary lung malignancy. In this modeling study, fractionation schedule did not have an impact on the risk of SLMs in women treated with whole-breast RT for early breast cancer.

Abstract
This study was undertaken to assess the diagnostic value of 2-[(18)F]-fluoro-2-deoxy-D-glucose positron emission tomography with computed tomography ([(18)F]-FDG-PET/CT) in the detection of radiation toxicity in normal bone marrow using Tibet minipigs as a model. Eighteen Tibet minipigs were caged in aseptic rooms and randomly divided into six groups. Five groups (n = 3/group) were irradiated with single doses of 2, 5, 8, 11 and 14 Gy of total body irradiation (TBI) using an 8-MV X-ray linear accelerator. These pigs were evaluated with [(18)F]-FDG-PET/CT, and their marrow nucleated cells were counted. The data were initially collected at 6, 24 and 72 h after treatment and were then collected on Days 5-60 post-TBI at 5-day intervals. At 24 and 72 h post-TBI, marrow standardized uptake value (SUV) data showed a dose-dependent decrease in the radiation dose range from 2-8 Gy. Upon long-term observation, SUV and marrow nucleated cell number in the 11-Gy and 14-Gy groups showed a continuous and marked reduction throughout the entire time course, while Kaplan-Meier curves of survival showed low survival. In contrast, the SUVs in the 2-, 5- and 8-Gy groups showed early transient increases followed by a decline from approximately 72 h through Days 5-15 and then normalized or maintained low levels through the endpoint; marrow nucleated cell number and survival curves showed approximately the same trend and higher survival, respectively. Our findings suggest that [(18)F]-FDG-PET/CT may be helpful in quickly assessing the absorbed doses and predicting the prognosis in patients.

Abstract
Most breast cancers originate in the epithelial cells lining the breast ducts. Intraductal administration of cancer therapeutics would lead to high drug exposure to ductal cells and eliminate preinvasive neoplasms while limiting systemic exposure. We performed preclinical studies in N-methyl-N'-nitrosourea-treated rats to compare the effects of 5-fluorouracil, carboplatin, nanoparticle albumin-bound paclitaxel, and methotrexate to the previously reported efficacy of pegylated liposomal doxorubicin (PLD) on treatment of early and established mammary tumors. Protection from tumor growth was observed with all five agents, with extensive epithelial destruction present only in PLD-treated rats. Concurrently, we initiated a clinical trial to establish the feasibility, safety, and maximum tolerated dose of intraductal PLD. In each eligible woman awaiting mastectomy, we visualized one ductal system and administered dextrose or PLD using a dose-escalation schema (2 to 10 mg). Intraductal administration was successful in 15 of 17 women with no serious adverse events. Our preclinical studies suggest that several agents are candidates for intraductal therapy. Our clinical trial supports the feasibility of intraductal administration of agents in the outpatient setting. If successful, administration of agents directly into the ductal system may allow for "breast-sparing mastectomy" in select women.

Abstract
Aims To investigate the technical feasibility of utilizing the Active Breathing Coordinator for planning of postoperative three-dimensional conformal radiation therapy in patients with early stage breast cancer undergoing breast conservation therapy. Methods Patients with early stage breast cancer for whom adjuvant radiotherapy after breast-conserving surgery was planned were consecutively enrolled. Five sessions of simulation with the Active Breathing Coordinator were planned for each patient. Computed tomography for simulation was not acquired until a good level of compliance with the procedure was achieved by the patient. Patients who did not show a satisfactory level of compliance after the planned fifth session were defined as noncom-pliant. Two simulation computed tomography scans were acquired: the first without the Active Breathing Coordinator during free breathing, the second with the Active Breathing Coordinator. Forward intensity-modulated treatment plans were calculated. Mean lung dose (MLDipsilateral) and V30 (V30lung) for the ipsilateral lung and V30 for the heart (V30heart), were evaluated. Results Twenty consecutive patients were enrolled (6 with left-sided breast cancer and 14 with right-sided breast cancer). Eighteen of the patients completed the simulation computed tomography with the Active Breathing Coordinator after 1–5 sessions (median, 3). In 16 of the 18 patients, a reduction of V30lung was observed with the Active Breathing Coordinator. In 15 of the 18 patients, a reduction of MLDipsilateral was also observed. In 5 of the 6 patients with left-sided breast cancer, a reduction of V30heart was noted. Conclusions Routine application of the Active Breathing Coordinator in clinical practice is feasible, even though it requires an increased workload. Dosimetric results are encouraging in terms of a better sparing of the ipsilateral lung and the heart.

Abstract
BACKGROUND The use of anthracycline chemotherapy is limited by the occurrence of cardiotoxicity. To prevent this cardiotoxicity, different anthracycline dosage schedules have been studied. OBJECTIVES To determine the occurrence of cardiotoxicity with the use of different anthracycline dosage schedules (i.e. peak doses and infusion durations) in cancer patients. SEARCH STRATEGY We searched the databases of The Cochrane Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 4, 2008), MEDLINE (1966 to November 2008) and EMBASE (1980 to November 2008). Also, we searched reference lists of relevant articles, conference proceedings and ongoing trials databases. SELECTION CRITERIA Randomised controlled trials (RCTs) in which different anthracycline dosage schedules were compared in cancer patients (children and adults). DATA COLLECTION AND ANALYSIS Two authors independently performed the study selection, the risk of bias assessment and the data-extraction. MAIN RESULTS We identified seven RCTs addressing different anthracycline infusion durations. The meta-analysis showed a statistically significant lower rate of clinical heart failure with an infusion duration of 6 hours or longer as compared to a shorter infusion duration (relative risk (RR) = 0.27; 95% confidence interval (CI) 0.09 to 0.81; 5 studies; 557 patients). The majority of patients included in these studies were adults with different solid tumours. For different anthracycline peak doses we identified two RCTs addressing a doxorubicin peak dose of less than 60 mg/m(2) versus 60 mg/m(2) or more, one RCT addressing a liposomal doxorubicin peak dose of 25 mg/m(2) versus 50 mg/m(2) and one RCT addressing an epirubicin peak dose of 83 mg/m(2) versus 110 mg/m(2). In none of the studies a significant difference in the occurrence of clinical heart failure was identified. All patients included in these studies were adults with different solid tumours. AUTHORS' CONCLUSIONS An anthracycline infusion duration of six hours or longer reduces the risk of clinical heart failure and it seems to reduce the risk of subclinical cardiac damage. Since there is only a small amount of data for children and data obtained in adults cannot be extrapolated to children, different anthracycline infusion durations should be evaluated further in children.No significant difference in the occurrence of clinical heart failure was identified in patients treated with a doxorubicin peak dose of less than 60 mg/m(2) or 60 mg/m(2) or more. For the other identified peak doses only one RCT was available, so no definitive conclusions can be made about the occurrence of cardiotoxicity. More high quality research is needed, both in children and adults and in leukaemias and solid tumours.

Abstract
BACKGROUND Postoperative radiotherapy after breast cancer surgery effectively reduces local relapses. A survival benefit after breast conservation, however, has only been proven recently which was in part due to excessive cardiac mortality of patients who had been treated with radiotherapy in the past. MATERIAL AND METHODS The literature on postoperative radiotherapy for breast cancer was reviewed with regard to cardiac toxicity as the basis for hypothesis generation. RESULTS From numerous publications on cardiac toxicity of breast cancer radiotherapy, the following pattern emerges: in series where a high radiation dose was applied to a significant percentage of the heart (postmastectomy and postlumpectomy series) cardiac toxicity/mortality was increased versus a nonexposed cohort or for left over right disease. If, however, a relevant exposure of cardiac muscle could be more or less excluded based on the technique used (mainly more recent postlumpectomy radiotherapy), no cardiac toxicity was observed. Series for which individual dose exposure varied or could not be clarified also came to varying conclusions. Also due to retrospectively unclear dose distributions, an exact quantification of tolerance doses/effects of different geographic dose distribution patterns could not be performed to date. A particularly difficult question to answer is the threshold volume for clinically relevant cardiotoxicity with tangential radiotherapy at prescription doses. As a consequence, this precludes an estimate in which situations multifield intensity-modulated radiotherapy (IMRT) with its characteristic dose distribution pattern of a larger volume exposed to intermediate doses and higher mean/median heart doses (as shown in Figure 1) might be preferable. CONCLUSION This review updates the database on cardiac toxicity of breast cancer radiotherapy with special emphasis regarding the issues related to the clinical use of IMRT. Multifield IMRT may reduce the cardiac risk for a small subset of patients at excessive risk with conventional tangential radiotherapy due to unfavorable thoracic geometry, for whom partial-breast radiotherapy is not an option. Due to further concern about the effects of intermediate doses to larger heart volumes, potentially increased contralateral cancer risk and the long latency of clinically apparent toxicity, the introduction of breast IMRT should be closely followed. Accompanying functional studies may have the potential to detect cardiac toxicity at an earlier time.

Abstract
BACKGROUND Breast conservation treatment for early-stage breast cancer has been demonstrated to be equivalent to mastectomy in a large number of randomized trials. A number of earlier studies of surgery with or without radiation did not show an improvement in overall survival despite large reductions in local recurrence rates. Numerous randomized trials have demonstrated that postmastectomy radiation to the chest wall and regional nodes in high-risk early-stage patients provides improvements in local-regional control and overall survival. METHODS This article reviews the medical literature pertaining to long-term cardiac toxicity in early-stage breast cancer patients treated with either breast conservation or postmastectomy radiation. RESULTS A decrease in breast cancer deaths associated with postoperative irradiation was offset by an increase in cardiovascular deaths in early studies. Cardiac toxicity of breast irradiation is a late event, manifesting clinically 10 or more years after breast cancer treatment. The excess deaths were directly related to radiation techniques that exposed excessive volumes of the heart, leading to the development of new techniques designed to shield the heart and reduce the risk of cardiac toxicity. CONCLUSIONS This review examines the original and contemporary studies of radiation for postmastectomy and breast conservation treatment for early-stage breast cancer, discusses the long-term cardiac mortality and morbidity data from these studies, and reviews the known risk factors associated with cardiac toxicity after irradiation for breast cancer.

Abstract
BACKGROUND Radiation therapy (RT) to the left breast/chest wall has been linked with cardiac dysfunction. Previously, the authors identified cardiac perfusion defects in approximately 50% to 60% of patients 0.5 to 2 years post-RT. In the current study, they assessed the persistence of these defects 3 to 6 years post-RT. METHODS From 1998 to 2006, 160 patients with left-sided breast cancer were enrolled onto an Institutional Review Board-approved, prospective study. All patients received tangential photons to the left breast/chest wall. Patients had pre-RT and serial post-RT single-photon emission computed tomography (SPECT) scans to assess changes in regional cardiac perfusion, wall motion, and ejection fraction (EF). Forty-four patients had SPECT scans 3 to 6 years post-RT and were evaluable for the current analysis. RESULTS The overall incidence of perfusion defects at 3 years, 4 years, 5 years, and 6 years was 52% (11 of 21 patients), 71% (17 of 24 patients), 67% (12 of 18 patients), and 57% (4 of 7 patients), respectively. The rate of abnormal SPECT scans 3 to 6 years post-RT in patients who had scans at 0.5 to 2 years that were either all abnormal, intermittently abnormal, or all normal was 80%, 67%, and 63%, respectively. The incidence of wall motion abnormalities in patients with or without perfusion defects 3 to 6 years post-RT was low and did not differ statistically (17% vs 7.1%, respectively; P = .65), as was the incidence of reductions in EF of >/=5% (27% vs 36%, respectively; P = .72). CONCLUSIONS The results from this study indicated that RT-induced perfusion defects may persist or initially may appear 3 to 6 years post-RT in a high percentage of patients. However, these defects were not associated with changes in regional wall motion or EF. Additional study will be needed to determine the clinical relevance of these defects. In the meantime, the authors believe that every effort should be made to minimize incidental irradiation of the heart while maintaining adequate coverage of target volumes.

Abstract
Cardiac toxicity has been implicated as the primary reason for excess non-breast cancer mortality in early breast cancer radiotherapy studies. Refinements in radiotherapy techniques have allowed for a considerable reduction of this risk in the majority of breast cancer patients. Recent large population-based studies confirmed an increase of cardiovascular death risk in patients irradiated for cancer of the left breast and in individuals exposed to relatively low (hitherto believed to be of no cardiovascular disease risk) doses of radiation, such as atomic bomb survivors or patients treated for various benign conditions. The issue of potential radiation-related cardiac damage may also be assuming a new significance due to the widespread use of other cardiotoxic agents, such as anthracyclines, paclitaxel and trastuzumab. The aim of this review is to summarize and critically analyze the available evidence on the impact of ionizing radiation on the cardiovascular system, with special attention to recent data demonstrating previously unrecognized adverse effects. This review discusses the pathology of radiation-related cardiovascular disease, its clinical presentation, risk factors and methods of assessment, as well as technical developments minimizing cardiac exposure. Epidemiological data are presented on the incidence of radiation-induced heart disease and cardiovascular mortality in various populations of patients irradiated for breast cancer and in individuals exposed to low radiation doses. Additionally, non-cardiac radiation-related vascular morbidity and mortality in breast cancer patients are addressed.

Abstract
BACKGROUND Radiation therapy (RT), a critical component of breast-conserving therapy for breast cancer, has been associated with coronary artery disease (CAD) in numerous older studies, but the risk may be lower with modern techniques. METHODS Observed rates of cardiac events in 828 patients treated with breast-conserving surgery and RT at the University of Michigan were compared with expected rates. Relations between potential risk factors and actuarial rates of first CAD event were analyzed. RESULTS Observed risks of cardiac events were lower than expected. The standardized incidence ratio (SIR) of myocardial infarction (MI) was 0.44 (95% confidence interval [CI]: 0.21-0.70). The SIR of MI or CAD requiring intervention was 0.50 (95% CI: 0.27-0.68). With a median follow-up of 6.8 years, 12 (1.4%) patients had at least 1 MI on follow-up and 20 (2.4%) had at least 1 MI or CAD requiring intervention. Median age at first cardiac event was 75.9 years (range, 43.1-91.5). Median interval from RT to occurrence of the first cardiac event was 3.7 years (range, 13 days to 15.4 years). The 10-year cumulative incidence of MI was 1.2% and cumulative incidence of MI or CAD requiring intervention was 2.7%. On multivariate analysis, age, diabetes mellitus, active smoking, and laterality of RT were significant predictors of MI. Age and active smoking were significant predictors of MI or CAD requiring intervention. CONCLUSIONS Patients in this series had lower risk of ischemic cardiac events than expected. Although small in absolute magnitude, patients radiated to the left side did have a statistically significant increased risk of MI. These findings support further investigation of techniques to minimize the long-term cardiac risks faced by breast cancer patients.

Abstract
PURPOSE The benefits of adjuvant radiation therapy (RT) for breast cancer may be counterbalanced by the risk of cardiac toxicity. We studied the cardiac effects of RT and the impact of pre-existing cardiac risk factors (CRFs) in a population-based sample of older patients with breast cancer. METHODS AND MATERIALS In the Surveillance, Epidemiology and End-Results (SEER)-Medicare database of women > or = 65 years diagnosed with Stages I to III breast cancer from January 1, 1992 to December 31, 2000, we used multivariable logistic regression to model the associations of demographic and clinical variables with postmastectomy and postlumpectomy RT. Using Cox proportional hazards regression, we then modeled the association between treatment and myocardial infarction (MI) and ischemia in the 10 or more years after diagnosis, taking the predictors of treatment into account. RESULTS Among 48,353 women with breast cancer; 19,897 (42%) were treated with lumpectomy and 26,534 (55%) with mastectomy; the remainder had unknown surgery type (3%). Receipt of RT was associated with later year of diagnosis, younger age, fewer comorbidities, nonrural residence, and chemotherapy. Postlumpectomy RT was also associated with white ethnicity and no prior history of heart disease (HD). The RT did not increase the risk of MI. Presence of MI was associated with age, African American ethnicity, advanced stage, nonrural residence, more than one comorbid condition, a hormone receptor-negative tumor, CRFs and HD. Among patients who received RT, tumor laterality was not associated with MI outcome. The effect of RT on the heart was not influenced by HD or CRFs. CONCLUSION It appears unlikely that RT would increase the risk of MI in elderly women with breast cancer, regardless of type of surgery, tumor laterality, or history of CRFs or HD, for at least 10 years.

Abstract
OBJECTIVE To describe the risk of acute myocardial infarction (AMI) after radiation therapy (RT) for breast cancer (BrCa) in an exposed population. METHODS We identified and validated cases of AMI (vAMI), by electrocardiographic or enzyme criteria, among all 6680 women who received post-operative RT following lumpectomy or mastectomy, within 12 months following diagnosis of BrCa between 1982 and 1988 in Ontario, Canada. We identified women without vAMI whose death certification was ascribed to AMI (dAMI). We abstracted risk factors and treatment exposures for a random sample of women from the 6680, and for all with vAMI or dAMI. The hazards of vAMI and of dAMI were estimated using multivariate Cox proportional hazards models, corrected for study design. RESULTS We validated 121 cases of vAMI and identified 92 cases of dAMI. The risk of vAMI associated with RT to the left breast HR=1.96 (1.09,3.54) among women at age >/= 60 at time of RT, adjusted for history of smoking and prior MI. The adjusted HR dAMI=1.90 (1.08,3.35) for exposure to anterior internal mammary node (IMC) RT. Among women who received anterior left breast boost RT, increasing area of the boost is associated with adjusted HR vAMI=1.02 (1.00,1.03)/cm(2), and adjusted HR dAMI=1.02 (1.01,1.03)/cm(2). CONCLUSION The risks of vAMI and dAMI following RT for BrCa are related to anatomic sites of RT (left breast, area of anterior left breast boost field, and anterior IMC field).

BACKGROUND The use of anthracycline chemotherapy is limited by the occurrence of cardiotoxicity. In an effort to prevent this cardiotoxicity, different anthracycline dosage schedules (i.e. peak doses and infusion durations) have been studied. OBJECTIVES The primary objective was to determine the occurrence of cardiotoxicity with the use of different anthracycline dosage schedules in cancer patients. SEARCH STRATEGY We searched the databases of The Cochrane Register of Controlled Trials (CENTRAL), (The Cochrane Library, Issue 2, 2004), MEDLINE (1966 to June 2004) and EMBASE (1980 to June 2004). In addition, we searched reference lists of relevant articles, conference proceedings and ongoing trials databases. SELECTION CRITERIA Randomised controlled trials (RCTs) in which different anthracycline dosage schedules were compared in cancer patients (children and adults). DATA COLLECTION AND ANALYSIS Two authors independently performed the study selection, quality assessment and data-extraction including adverse effects. MAIN RESULTS We identified six RCTs of varying quality addressing different anthracycline infusion durations (625 patients). The meta-analysis showed a statistically significant lower rate of clinical heart failure with an infusion duration of 6 hours or longer as compared to a shorter infusion duration, i.e. maximal duration of 1 hour (RR = 0.27; 95% confidence interval (CI) 0.09 to 0.81; 5 studies; 557 patients). In individual studies the infusion duration of 6 hours or longer also seemed to reduce the risk of subclinical cardiac damage. No statistically significant difference in response rate was found (RR = 0.83; 95% CI 0.45 to 1.54; 2 studies; 292 patients). No statistically significant difference in overall survival was found (HR = 1,42; 95% CI 0.61 to 3.30; 2 studies; 322 patients), but there was unexplained heterogeneity (I(2)=75%). No conclusions can be made regarding adverse effects. It should be emphasised that the majority of patients included in these studies were adults with different solid tumours. Children with leukaemia could not be included in the performed meta-analyses, but they were included in the descriptive results of non-pooled studies. No RCTs addressing different anthracycline peak doses with the same cumulative anthracycline dose in both treatment groups were identified. AUTHORS' CONCLUSIONS An anthracycline infusion duration of six hours or longer reduces the risk of clinical heart failure, and it seems to reduce the risk of subclinical cardiac damage. There is no evidence which suggests a difference in response rate and survival between both treatment groups. Since there is only a small amount of data for children and also because data obtained in adults cannot be extrapolated to children, different anthracycline infusion durations should be evaluated further in children. For different anthracycline peak doses no high quality evidence was available and therefore, no definitive conclusions can be made about the occurrence of cardiotoxicity in patients treated with different anthracycline peak doses.

Abstract
Although the beneficial effect of postoperative radiotherapy for breast cancer is well documented, this treatment may be related to a number of complications, which may affect patient quality of life and possibly survival. Among significant long-term irradiation sequelae are cardiac and lung damage, lymphoedema, brachial plexopathy, impaired shoulder mobility and second malignancies. The risk of these complications, particularly high with old, suboptimal irradiation techniques, has decreased with the introduction of modern technologies. In this paper, we review the contemporary knowledge on the toxicity of breast-cancer radiotherapy and discuss possible preventive measures.

Abstract
In this paper we determine if preoperative chemoradiation for locally advanced esophageal cancer leads to changes in cardiac ejection fraction. This is a retrospective review of 20 patients treated at our institution for esophageal cancer between 2000 and 2002. Multiple gated acquisition cardiac scans were obtained before and after platinum-based chemoradiation (50.4 Gy). Dose-volume histograms for heart, left ventricle and left anterior descending artery were analyzed. Outcomes assessed included pre- and postchemoradiation ejection fraction ratio and percentage change in ejection fraction postchemoradiation. A statistically significant difference was found between median prechemoradiation ejection fraction (59%) and postchemoradiation ejection fraction (54%) (P = 0.01), but the magnitude of the difference was not clinically significant. Median percentage volume of heart receiving more than 20, 30 and 40 Gy were 61.5%, 58.5% and 53.5%, respectively. Our data showed a clinically insignificant decline in ejection fraction following chemoradiation for esophageal cancer. We did not observe statistically or clinically significant associations between radiation dose to heart, left ventricle or left anterior descending artery and postchemoradiation ejection fraction.

Abstract
Purpose Adjuvant breast irradiation has been associated with an increase in cardiac mortality, because left-sided breast radiation can produce cardiac damage. The purpose of this study was to determine whether modern adjuvant radiotherapy is associated with increased risk of cardiac morbidity. Patients and Methods Data from the Surveillance, Epidemiology, and End Results–Medicare database were used for women who were diagnosed with nonmetastatic breast cancer from 1986 to 1993, had known disease laterality, underwent breast surgery, and received adjuvant radiotherapy. The Cox proportional-hazards model was used to compare patients with left- versus right-sided breast cancer for the end points of hospitalization with the following discharge diagnoses (International Classification of Diseases, 9th Revision codes): ischemic heart disease (410-414, 36.0, and 36.1), valvular heart disease (394-397, 424, 35), congestive heart failure (428, 402.01, 402.11, 402.91, and 425), and conduction abnormalities (426, 427, 37.7-37.8, and 37.94-37.99). Results Eight thousand three hundred sixty-three patients had left-sided breast cancer, and 7,907 had right-sided breast cancer. Mean follow-up was 9.5 years (range, 0 to 15 years). There were no significant differences in patients with left- versus right-sided cancers for hospitalization for ischemic heart disease (9.9% v 9.7%), valvular heart disease (2.9% v 2.8%), conduction abnormalities (9.7% v 9.6%), or heart failure (9.7% v 9.7%). The adjusted hazard ratio for left- versus right-sided breast cancer was 1.05 (95% CI, 0.94 to 1.16) for ischemic heart disease, 1.07 (95% CI, 0.89 to 1.30) for valvular heart disease, 1.07 (95% CI, 0.96 to 1.19) for conduction abnormalities, and 1.05 (95% CI, 0.95 to 1.17) for heart failure. Conclusion With up to 15 years of follow-up there were no significant differences in cardiac morbidity after radiation for left- versus right-sided breast cancer.

Abstract
PURPOSE OF REVIEW The past decade has seen significant advances in the delivery of radiotherapy for breast cancer. This article presents an overview of the most recent advances in radiotherapy for early breast cancer with emphasis on English-language articles published since 1 July 2003. RECENT FINDINGS Breast radiotherapy is usually well tolerated. However, the uptake of radiotherapy in the management of breast cancer is less than ideal. Recent research efforts in radiation oncology have concentrated on addressing the uptake of appropriate radiotherapy by quantifying toxicity, further reducing toxicity, and improving the convenience of radiotherapy. Novel radiation techniques such as partial breast irradiation and shortened radiotherapy treatment courses are under development to make radiotherapy more acceptable to patients and referring clinicians. Issues such as the optimal timing of radiotherapy after surgery and integrating the radiation with newer adjuvant systemic therapies remain important research challenges. SUMMARY Radiotherapy remains an important component of breast cancer therapy. Improving the acceptance of treatment and minimizing toxicity and inconvenience of treatment should lead to even greater appropriate use.

Abstract
PURPOSE OF REVIEW Radiotherapy has been one of the cornerstones of treatment for breast cancer for more than a century and has contributed to conservation of the breast and improved locoregional control after mastectomy. This review assesses the most recent evidence generated by clinical scientists in the field of radiotherapy for breast cancer. RECENT FINDINGS Results from mature trials investigating the role of radiotherapy in breast cancer treatment and the publication of meta-analyses of treatment effects have shown that in addition to improvements in local control, a survival benefit is obtained in several disease settings. These include breast-conserving therapy and postmastectomy radiotherapy. Further, improved diagnostic abilities and surgical techniques, together with advances in treatment delivery, will help to increase the therapeutic ratio of radiotherapy. SUMMARY There is increasing evidence for long-term benefits of radiotherapy for breast cancer and a reduction in the risks of late side effects in recent decades. This can have a profound impact on clinical practice in the future, leading to a broadening and individualizing of the indications for radiotherapy and improvements in patient survival.

Abstract
As systemic therapy of metastatic breast cancer improves, CNS involvement is becoming a more widespread problem. This article summarizes the current knowledge regarding the incidence, clinical presentation, diagnosis, prognosis, and treatment of CNS metastases in patients with breast cancer. When available, studies specific to breast cancer are presented; in studies in which many solid tumors were evaluated together, the proportion of patients with breast cancer is noted. On the basis of data from randomized trials and retrospective series, neurosurgery and stereotactic radiosurgery (SRS) may prolong survival in patients with single brain metastases. The treatment of multiple metastases remains controversial, as does the routine use of whole-brain radiotherapy (WBRT) after either surgery or SRS. Although it is widely assumed that chemotherapy is of limited benefit, data from case series and case reports suggest otherwise. WBRT, neurosurgery, SRS, and medical therapy each have a role in the treatment of CNS metastases; however, neurologic symptoms frequently are not fully reversible, even with appropriate therapy. Studies specifically targeted toward this group of patients are needed.

Abstract
Intensity-modulated radiotherapy (IMRT) is a novel conformal radiotherapy technique which is gaining increasingly widespread use. This second clinical article aims to summarize the published data pertaining to prostate cancer, pelvic irradiation, gynaecological and breast cancer. Prostate cancer patients represent the largest group treated to date. The main indication has been radiation dose escalation within acceptable normal tissue late toxicity. Phase II data are promising, but no randomized clinical trial data are available to support its use. Pelvic IMRT aims to deliver radical radiation doses to pelvic lymph nodes while sparing the bowel and bladder. Indications for breast IMRT data are reviewed, and current data presented. Further data from randomized trials are required to confirm the anticipated benefits of IMRT in patients.
