Article: Anticipatory nausea and vomiting.
[show abstract] [hide abstract]
ABSTRACT: A commonly reported consequence of post-treatment nausea or vomiting is the development of anticipatory nausea and vomiting (ANV). In most published work, nausea is reported to occur before chemotherapy drugs are administered by approximately 20% of patients at any one chemotherapy cycle and by 25-30% of patients by their fourth chemotherapy cycle. Most studies in adult patients strongly support the view that the development of ANV involves elements of classical conditioning. The best method to avoid development of ANV is to adequately prevent both vomiting and nausea from the first exposure to chemotherapy. If anticipatory side effects develop, behavioral treatment techniques, such as systematic desensitization, have been shown effective. Benzodiazepines used in combination with behavioral techniques or antiemetics may also be useful. The evidence on which these conclusions are based is reviewed in this article.Supportive Care in Cancer 10/2011; 19(10):1533-8. · 2.09 Impact Factor -
Article: Bone health management in patients with breast cancer: current standards and emerging strategies.
[show abstract] [hide abstract]
ABSTRACT: In women who develop bone metastases from breast cancer (BC), interactions between tumor cells and osteoclasts within the bone lead to localized bone destruction and increase the risk of skeletal-related events (SREs). Bisphosphonates inhibit osteoclast-mediated bone resorption, and have been used extensively for treating post-menopausal osteoporosis and reducing the risk of SREs in patients with bone metastases. A number of clinical trials in women with early stage BC have demonstrated that adding bisphosphonates to adjuvant endocrine therapy can prevent bone loss and may prevent disease recurrence and improve disease-free survival. In women with bone metastases from BC, bisphosphonates have demonstrated efficacy for reducing skeletal morbidity and pain and improving quality of life. Recent economic analyses have demonstrated that bisphosphonate therapy is a cost-effective use of healthcare resources. This review summarizes the available data for bisphosphonate benefits in both the adjuvant and metastatic settings in the context of evolving clinical practice.Breast (Edinburgh, Scotland) 09/2011; 21(1):8-19. · 2.09 Impact Factor -
Article: Challenges in clinical patient management.
[show abstract] [hide abstract]
ABSTRACT: The use of endocrine therapy in breast cancer represents one of the earliest molecular targeting strategies used in cancer treatment. Tamoxifen, a selective estrogen-receptor (ER) modulator, has been the standard of care for women with receptor-positive breast cancer for the last 30 years. Tamoxifen suppresses the estrogen-dependent growth of breast cancer cells by specifically targeting the ER. Because of estrogenic effects, tamoxifen does not increase the risk of osteoporosis, but it can lead to endometrial cancer and thromboembolism. The third-generation aromatase inhibitors (AIs) exert their tumor antiproliferative action by targeting an enzyme critical for estrogen biosynthesis. The AIs thus have a different mechanism of action than tamoxifen, and a different safety profile. The majority of adverse events (AEs) related to the AIs are mild to moderate. Most of these AEs are common to menopause and are predictable and manageable. This review looks at AI-associated side effects and current clinical management strategies, with a particular emphasis on managing bone health. Compliance with long-term therapy, strategies to improve adherence, and considerations in elderly patients with hormone-responsive breast cancer are also discussed.Cancer Investigation 01/2010; 28 Suppl 1:14-27. · 1.85 Impact Factor -

Article: September 2007 update on EORTC guidelines and anemia management with erythropoiesis-stimulating agents.
[show abstract] [hide abstract]
ABSTRACT: Anemia is frequently experienced by cancer patients receiving chemotherapy and can negatively impact the patient's prognosis. Blood transfusions, iron supplementation (in absolute or functionally iron-deficient anemias), and erythropoiesis-stimulating agents (ESAs) are among the treatment options for anemia. Treatment options for anemia management should be selected based on the best benefit-to-risk ratio for each individual patient. In September 2007, the working party of the European Organization for Research and Treatment of Cancer (EORTC) updated their guidelines on the use of ESAs, which are summarized in this paper. ESAs reduce the number of transfusions required and significantly improve quality of life in patients with chemotherapy-induced anemia. A sustained hemoglobin level of about 12 g/dl should be the target for treatment with ESAs. ESAs should be used according to the EORTC guidelines and within label with carefully considered exceptions.The Oncologist 02/2008; 13 Suppl 3:33-6. · 3.91 Impact Factor -
Article: Management of bisphosphonate treatment in clinical practice.
[show abstract] [hide abstract]
ABSTRACT: Bisphosphonates have become important tools for the treatment of bone lesions from various solid tumors or from multiple myeloma. Management of bone health in patients with malignant bone disease from breast cancer, prostate cancer, lung cancer, and multiple myeloma was discussed in clinical case workshops held during the ZENITH meeting (April 2007, Prague, Czech Republic). Physicians in attendance were generally in agreement that bisphosphonate therapy is recommended for treatment of bone metastases and that treatment should be sustained over the duration of disease progression. Consensus is still evolving regarding the optimal duration of therapy and the emerging role of bisphosphonates in the management of bone loss in the adjuvant setting. Bisphosphonates have proven efficacy in reducing and delaying skeletal-related events in patients with bone metastases, and play a key role in preserving patient functional independence and quality of life. Furthermore, bisphosphonate therapy is a cost-effective strategy in the care of patients with bone metastases compared with the cost of treatment for fractures and other skeletal complications. Finally, communication with patients is critical to increase awareness of the benefits of bisphosphonate therapy. Increased patient involvement with treatment decisions will likely encourage patient compliance and thereby maximize clinical benefit from bisphosphonate therapy.Seminars in Oncology 01/2008; 34(6 Suppl 4):S28-32. · 3.50 Impact Factor -
Article: Role of colony stimulating factors (CSFs) in solid tumours: results of an expert panel.
[show abstract] [hide abstract]
ABSTRACT: Febrile neutropenia is a relatively frequent event in cancer patients treated with chemotherapy. A relevant body of scientific evidence has been produced in the last 2 decades, through clinical trials addressing the efficacy of colony stimulating factors (CSFs) in the prevention and treatment of febrile neutropenia. The correct use of CSFs needs to be optimized, and several guidelines have been produced and periodically updated, in order to uniform and guide clinical practice. The aim of this review is to synthesize the most relevant clinical trials and the most important existing guidelines about the role of CSFs in solid tumours. Role of CSFs as primary prophylaxis, secondary prophylaxis and treatment of afebrile and febrile neutropenia is discussed. A special focus is dedicated to neutropenia and the use of CSFs in the treatment of the three "big killers" among the solid tumours: breast cancer, lung cancer and colorectal cancer.Critical Reviews in Oncology/Hematology 08/2007; 63(1):53-64. · 4.41 Impact Factor -
Article: Oral vinorelbine: role in the management of metastatic breast cancer.
[show abstract] [hide abstract]
ABSTRACT: The treatment of advanced breast cancer is continually evolving, with the aim of improving the quality and duration of remission and, in some instances, survival. In this setting, the importance of quality of life cannot be underestimated, and growing attention is being paid to treatment convenience and compliance. New anticancer agents have improved efficacy, but for many of them, toxicity often remains a problem. Vinorelbine seems to represent both an active and a well tolerated treatment for metastatic breast cancer. In particular, the oral formulation has similar efficacy to that of the injectable formulation and has demonstrated generally favourable tolerability, with a high degree of acceptance by both patients and physicians. The availability of this and other novel, well tolerated and effective treatments provides greater potential to tailor treatment to meet individual patient needs and, therefore, also provide the potential to improve patient outcomes. Preliminary data suggest that oral vinorelbine may permit continued, effective chemotherapy when further parenteral therapy with more intensive and more toxic agents is considered inappropriate. Early findings also suggest that oral vinorelbine, when administered together with another new oral agent, capecitabine, may be a valid choice in metastatic breast cancer treatment. Furthermore, vinorelbine plus the monoclonal antibody trastuzumab, with or without oral capecitabine, appears to be another regimen that may be worthy of additional study in patients with human epidermal growth factor-2 positive advanced breast cancer.Drugs 02/2007; 67(5):657-67. · 4.23 Impact Factor -
Article: Epoetin alfa increases hemoglobin levels and improves quality of life in anemic geriatric cancer patients receiving chemotherapy.
[show abstract] [hide abstract]
ABSTRACT: To evaluate epoetin alfa (EPO) treatment of anemia in geriatric cancer patients receiving chemotherapy, a retrospective subgroup analysis was conducted of anemic cancer patients > or =65 years of age from three 16-week community-based studies of thrice-weekly (TIW) or once-weekly (QW) EPO for chemotherapy-related anemia (CRA). Analyses were conducted on the overall geriatric population (> or =65 years) and by age subgroup (65-74, 75-84, and > or =85 years), and compared with younger patients (<65 years) for each individual study and for pooled data. Some 3,634 geriatric patients were compared with 3,467 younger patients. From baseline to final measurement, EPO therapy significantly increased Hb by 2.0 g/dl in patients > or =65 years and 1.9 g/dl in patients <65 years (P<0.0001) and reduced transfusion utilization in both groups (P<0.006). Both age groups also had significant improvements in quality of life (QOL), measured by the 100-mm Linear Analog Assessment Scale (LASA). In younger patients, mean LASA changes were significantly greater than those in geriatric patients (P<0.05); however, QOL improvements in both age groups were clinically meaningful. There were no significant differences across geriatric age subgroups or between TIW and QW regimens for Hb change or QOL improvement. Overall hematopoietic response rate to EPO was 65.4% for patients > or =65 years and 64.7% for patients <65 years. Predictors of greater hematopoietic response (based on a pooled analysis) included lower body weight, baseline Hb, and baseline serum erythropoietin levels; better tumor response; and history of EPO dose reduction and longer time on study. Anemic geriatric patients receiving EPO for CRA responded comparably to younger patients <65 years and should be treated similarly.Supportive Care Cancer 12/2006; 14(12):1184-94. · 2.60 Impact Factor -
Article: Anticipatory nausea and vomiting.
[show abstract] [hide abstract]
ABSTRACT: Anticipatory nausea and vomiting (ANV) is not only a learned response but can occur without prior exposure to chemotherapy depending on patient emotional distress and expectations. The best method to avoid development or reinforcement of ANV is to avoid both vomiting and nausea from the first exposure to chemotherapy. If ANV develops, benzodiazepines have been documented to help in adult patients, and several psychological techniques are also of help, including systematic desensitization. The evidence on which these conclusions are based is reviewed in this article.Supportive Care Cancer 03/2005; 13(2):117-21. · 2.60 Impact Factor -
Article: Never too old? Age should not be a barrier to enrollment in cancer clinical trials.
[show abstract] [hide abstract]
ABSTRACT: Throughout Europe and the U.S., over 60% of the total incidence of cancer occurs in the elderly (> or =65 years) population, a patient group that requires particular consideration when making treatment decisions due to a number of factors. Despite this, elderly patients are generally under-represented in clinical trials such that study data should be interpreted with caution because results in younger cancer patients may not always extrapolate to the typical elderly cancer patient. Reports suggest that elderly cancer patients represent around 22% of patients enrolled in phase II clinical studies. Barriers to the accrual of elderly patients to clinical trials include lack of appropriate trials, high burden of comorbidity, study-imposed restrictions, and attitudes of physicians. There is a belief that elderly patients may be unable to tolerate various cancer therapies, which may result in this patient population being excluded from prospective trials. However, clinical data demonstrate that age alone is not a sufficient reason to withhold treatment. Lack of clinical trial data and the associated lack of evidence-based guidelines for elderly patients mean physicians have little to guide them, with the result that patients may not receive the optimal therapy. As clinical trials are the primary method of evaluating the efficacy and safety of adjuvant and palliative cancer therapies, trials that specifically target the elderly cancer patient are required to adequately assess the risks and benefits of treatment in this vulnerable population. This review aims to assess the clinical reality and clinical trial age mismatch to evaluate implications for elderly cancer patients and to identify how this situation may be addressed. Possible reasons for the disparity, and the resulting clinical consequences, are also considered.The Oncologist 03/2005; 10(3):198-204. · 3.91 Impact Factor -
Article: Cancer-related anemia: pathogenesis, prevalence and treatment.
[show abstract] [hide abstract]
ABSTRACT: Cancer-related anemia is a cytokine-mediated disorder resulting from complex interactions between tumor cells and the immune system. Overexpression of certain inflammatory cytokines results in shortened survival of red blood cells, suppression of erythroid progenitor cells, impaired iron utilization, and inadequate erythropoietin production. Numerous other factors may also contribute to the development of anemia in cancer patients. The European Cancer Anaemia Survey (ECAS) has provided the most current, comprehensive, prospectively collected data on the incidence and prevalence of anemia among cancer patients, as well as important perspectives on anemia treatment and relationship of hemoglobin and performance status. ECAS enrolled over 15,000 treated and untreated patients with various malignancies from cancer centers in 24 European countries and followed them for up to 6 months. The initial analysis of the ECAS data revealed that 39% of the total cancer patient population was anemic (hemoglobin <12.0 g/dl) at enrollment, although the rate varied according to tumor type, disease status, and cancer treatment status. Of the patients who were not anemic at enrollment and started cancer treatment during the survey, those undergoing chemotherapy--either alone or in combination with radiotherapy--had the highest incidence of anemia (63 and 42%, respectively). Low hemoglobin levels correlated with poor performance status and only 40% of patients who were anemic at some time during the survey received treatment for their anemia. These findings are noteworthy, since a growing body of clinical evidence indicates that the treatment of anemia can significantly improve patients' quality of life and may also improve the clinical outcome.Oncology 02/2005; 68 Suppl 1:3-11. · 2.27 Impact Factor -

Article: Long-term implications of bone loss in breast cancer.
[show abstract] [hide abstract]
ABSTRACT: Cancer treatment-induced bone loss (CTIBL) is an emerging problem during long-term adjuvant therapy with aromatase inhibitors or ovarian-ablative therapy. CTIBL increases the risk of skeletal complications. Patients receiving adjuvant therapy for breast cancer should receive periodic bone mineral density (BMD) assessments, and those with clinically significant bone loss should be treated with bisphosphonates. Intravenous (i.v.) bisphosphonates (e.g., zoledronic acid) appear to be a very effective treatment for CTIBL. Recently, the Austrian Breast and Colorectal Cancer Study Group 012 trial reported that i.v. zoledronic acid (4 mg every 6 months) maintained BMD in premenopausal women receiving goserelin with either tamoxifen or anastrozole. The Z-FAST and ZO-FAST trials are comparing i.v. zoledronic acid (4 mg every 6 months) up front with letrozole versus initiation when patients exhibit lumbar-spine BMD T-scores > or =2 standard deviations below normal (i.e., T-score < or =-2.0). These studies will provide important insight into the management of CTIBL.The Breast 01/2005; 13 Suppl 1:S29-37. · 2.49 Impact Factor -
Article: Age, anemia, and fatigue.
[show abstract] [hide abstract]
ABSTRACT: Many conditions that would not be considered normal in a younger population are routinely accepted in older people as a part of so-called "normal" aging. Among these conditions are many chronic and debilitating conditions such as chronic pain, insomnia, weakness, fatigue, and anemia. This article reviews current evidence regarding the relationships among age, fatigue, weakness, anemia, and erythropoiesis. Anemia in the elderly is important because it can lead to weakness, fatigue, limitations in activity, and may increase cardiovascular risk. Recent studies of the effect of erythropoietin in an aging population support the hypothesis that anemia is associated with pathologic factors and not with normal aging. While older individuals admitted to hospitals are more likely to be anemic, these same individuals have a bone marrow mass and numbers of cultured progenitor cells that are similar to that of the younger population; therefore, the predicted response to erythropoietin, and thus the function of the bone marrow and cellular progenitors, is maintained. Thus, we can conclude that anemia is a correctable pathologic finding in elderly people. A number of studies have shown a strong relationship between fatigue and anemia, but few studies investigate to what degree age is a factor in weakness and fatigue. In a study of 375 anemic cancer patients with a median age of 61 years, age as a covariate in multiple linear regression analysis failed to reach significance for most measures of function and quality of life (QOL), including measures of energy, activities, mental health, general cancer-related QOL, and overall QOL. Additional analysis suggests that other factors, including cancer progression, hemoglobin change, and baseline hemoglobin levels, are much more important in determining change in functional and quality-of-life scores. In another set of 2,000 cancer patients and 1,000 controls, cancer patients experienced significantly more fatigue compared with controls. There was no correlation between cancer patient age and fatigue, while in controls the cohort aged 65 or more reported more fatigue than did younger subjects. Finally, measurement of QOL in the general population demonstrated, for both the Short-Form 36 and Functional Assessment of Cancer Therapy - Anemia questionnaires, that age alone is not significantly correlated with QOL. We suggest that chronic conditions such as fatigue and anemia are no more "normal" in an aging population than in a general population, and that all patients with chronic conditions be adequately treated and counseled for their condition.Seminars in Oncology 07/2002; 29(3 Suppl 8):55-9. · 3.50 Impact Factor -
Article: Comprehensive geriatric assessment adds information to Eastern Cooperative Oncology Group performance status in elderly cancer patients: an Italian Group for Geriatric Oncology Study.
[show abstract] [hide abstract]
ABSTRACT: To appraise the performance of Comprehensive Geriatric Assessment (CGA) in elderly cancer patients (> or = 65 years) and to evaluate whether it could add further information with respect to the Eastern Cooperative Oncology Group performance status (PS). We studied 363 elderly cancer patients (195 males, 168 females; median age, 72 years) with solid (n = 271) or hematologic (n = 92) tumors. In addition to PS, their physical function was assessed by means of the activity of daily living (ADL) and instrumental activities of daily living (IADL) scales. Comorbidities were categorized according to Satariano's index. The association between PS, comorbidity, and the items of the CGA was assessed by means of logistic regression analysis. These 363 elderly cancer patients had a good functional and mental status: 74% had a good PS (ie, lower than 2), 86% were ADL-independent, and 52% were IADL-independent. Forty-one percent of patients had one or more comorbid conditions. Of the patients with a good PS, 13.0% had two or more comorbidities; 9.3% and 37.7% had ADL or IADL limitations, respectively. By multivariate analysis, elderly cancer patients who were ADL-dependent or IADL-dependent had a nearly two-fold higher probability of having an elevated Satariano's index than independent patients. A strong association emerged between PS and CGA, with a nearly five-fold increased probability of having a poor PS (ie, > or = 2) recorded in patients dependent for ADL or IADL. The CGA adds substantial information on the functional assessment of elderly cancer patients, including patients with a good PS. The role of PS as unique marker of functional status needs to be reappraised among elderly cancer patients.Journal of Clinical Oncology 01/2002; 20(2):494-502. · 18.37 Impact Factor -
Article: Palonosetron improves prevention of chemotherapy-induced nausea and vomiting in elderly patients.
[show abstract] [hide abstract]
ABSTRACT: Although elderly patients have been reported to be less prone to chemotherapy-induced nausea and vomiting (CINV), its management is complicated by a high frequency of comorbidities and polypharmacy and an increased risk of dehydration and impaired cognition. The comparative efficacy and tolerability of palonosetron and ondansetron/dolasetron were assessed in a retrospective post hoc analysis using pooled data from 171 elderly patients (age > or = 65 years) with cancer enrolled in two randomized, double-blind, phase III clinical studies comparing single IV doses of these antiemetic agents given prior to receipt of moderately emetogenic chemotherapy. The complete response rate during the postchemotherapy period was significantly higher in the palonosetron group than in the ondansetron/dolasetron group in the 5 days following chemotherapy. The proportion of patients who were nausea-free on the problematic days 2 and 3 post chemotherapy and the time to treatment failure also significantly favored palonosetron. In this population that included patients with pre-existing comorbidities, palonosetron was well tolerated, with similar or fewer adverse events than the comparators. Comparisons in electrocardiogram parameters revealed that the mean postdose change from baseline in QTc interval was 3 ms for palonosetron 0.25 mg and 5 ms for ondansetron/dolasetron. In this retrospective analysis, palonosetron provided superior efficacy to ondansetron/dolasetron for the treatment of CINV in elderly patients receiving moderately emetogenic chemotherapy. Based on its safety profile, antiemetic control, and convenient dosing, palonosetron can be recommended for use in elderly patients with cancer receiving emetogenic chemotherapy.The journal of supportive oncology 3(5):369-74.
