Androgen-deprivation therapy (ADT) is a common treatment for men with prostate cancer. Although ADT is effective at suppressing prostate-specific antigen (PSA), stabilizing disease, alleviating symptoms in advanced disease, and potentially prolonging survival, it is not without serious side effects. However, to the authors' knowledge, there is lack of a systematic review of its major adverse effects to date. The authors of this report systematically reviewed and quantitatively assessed the literature on skeletal and cardiac side effects associated with ADT in men with prostate cancer. The PubMed database was searched for relevant published articles from 1966 to May 2008, and 683 articles were reviewed systematically from an original 20 different Medical Subject Heading search combinations. The focus of the review was on bone-related and cardiovascular-related outcomes. When appropriate, results were pooled from articles on specific adverse outcomes, summary risk estimates were calculated, and tests of heterogeneity were performed. Fourteen articles were identified that met inclusion criteria from the original 683 studies. Men who underwent ADT for prostate cancer had a significantly increased risk of overall fracture of 23% (summary relative risk, 1.23; 95% confidence interval [95% CI], 1.10-1.38) compared with men who had prostate cancer but who did not undergo ADT. Furthermore, men who underwent ADT had a 17% increase in cardiovascular-related mortality compared with men who did not undergo with ADT (summary hazards ratio, 1.17; 95% CI, 1.07-1.29). Significant elevations in the risk of diabetes also were observed from 2 large studies. ADT was associated with an increased risk of skeletal fracture, incident diabetes, and cardiovascular-related mortality, although the absolute risk of these events was low. Preventive measures against these adverse effects and careful assessment of patient's baseline health status should be considered.

Homeopathic medicines are used by patients with cancer, often alongside conventional treatment. Cancer treatments can cause considerable morbidity and one of the reasons patients use homeopathic medicines is to help with adverse effects.

Tetrathiomolybdate (TM) is a novel anticancer and anti-angiogenic agent, which acts through copper chelation and NF-kappaB inhibition.

Various nonhormonal agents have been used for the treatment of hot flashes in women with natural or tamoxifen-induced menopause. Some studies have reported that gabapentin appears to be an effective and well-tolerated treatment modality.

Aromatase inhibitors (AIs) are now regarded as the optimum hormonal therapy for postmenopausal women with hormone receptor positive breast cancer. However, it is unclear which of the currently available AIs offers patients the most effective and the best-tolerated treatment strategy. We performed a systematic review and meta-analysis of randomized-controlled trials that compared AIs (as first-line agents) with standard hormonal treatment in patients with breast cancer. The results suggest that letrozole offers a more favorable side-effect profile particularly in terms of musculoskeletal adverse events. However, the available data suggests a small survival benefit from the use of anastrozole although patients treated with anastrozole appear to have a more favorable disease profile at study entry. Examination of survival data on adjuvant tamoxifen therapy from these trials supports this observation.

Anthracyclines are used to treat childhood acute lymphoblastic leukaemia (ALL) but non-randomized studies suggest that cardiotoxicity may be a problem. Individual patient data from trials in childhood ALL that randomized anthracyclines or methods of reducing cardiotoxicity were analysed by standard meta-analysis methods. Results were grouped and combined according to: addition of an anthracycline to standard therapy, type of anthracycline, mode of administration, and the use of a cardioprotectant. Data from 958 patients in 4 trials, recruiting between 1972 and 1984, showed that addition of an anthracycline reduced bone marrow relapse and, non-significantly, non-bone marrow relapse, resulting in an increased relapse-free interval. However there was a non-significant increase in induction failures, and in deaths in first remission. Event-free survival at 5 years was 56.7% with anthracycline versus 52.8% without (Odds Ratio = 0.91; 95% Confidence Interval = 0.76-1.10; P = 0.3). There were no significant differences found in other treatment comparisons. The limited data from trials did not demonstrate differences in clinically evident cardiotoxicity. Anthracyclines are effective against bone marrow relapse but have not been shown to significantly increase event free survival in childhood ALL. The evidence on type of anthracycline, method of administration or use of cardioprotectant was insufficient to be able to rule out important differences.

Hand-foot skin reaction (HFSR) is an emerging issue in cancer treatment with multitargeted tyrosine kinase inhibitors (TKIs), leading to morbidity, suboptimal dosing, and poor compliance. The overall risk of HFSR is not clear for sunitinib, a TKI effective for metastatic renal cell carcinoma (RCC) and gastrointestinal stromal tumor. We therefore conducted a systematic review and a meta-analysis to determine the risk of developing HFSR with sunitinib. Databases from PubMed and Web of Science for articles from July 1966 until July 2007 and abstracts presented at the American Society of Clinical Oncology conferences were searched to identify relevant studies. Eligible studies were prospective clinical trials that had described events of HFSR for patients who received singleagent sunitinib. Incidence and relative risk (RR) were calculated using a random-effects or fixed-effects model. A total of 5005 patients with RCC and other cancers from 10 clinical trials were included for analysis. Among patients receiving sunitinib, the summary incidences of all-grade and high-grade HFSR were 18.9% (95% CI, 14.1%-24.8%) and 5.5% (95% CI, 3.9%-7.9%), respectively. Interestingly, patients with RCC have significantly decreased risk of HFSR compared with patients with non-RCC malignancy (RR, 0.56; 95% CI, 0.50-0.64; P < .001). In addition, sunitinib was associated with a significantly increased risk of all-grade HFSR (RR, 9.86; 95% CI, 3.1-31.31; P < .001) in comparison with controls. There is a significant risk of developing HFSR in patients with cancer receiving sunitinib. Adequate monitoring and intervention are recommended for reducing the toxicity.

Follicular lymphoma is characterized by slow growth and an initially high rate of response to treatment, but patients typically relapse and experience progressive disease. Rituximab in combination with chemotherapy has been shown to improve overall survival in patients with follicular lymphoma compared with chemotherapy alone, but data from randomized clinical trials evaluating rituximab maintenance treatment in these patients are limited. We aimed to evaluate the effect of maintenance treatment with rituximab on the overall survival of patients with follicular lymphoma.

We aimed to assess the incidence of febrile neutropenia in patients with non small cell lung cancer treated with docetaxel as second line chemotherapy by systematic review and meta-analysis of clinical studies. Published studies were retrieved and included if they considered docetaxel at the licensed dose after a previous chemotherapy regimen, and reported the proportion of patients getting FN. Meta-analysis was conducted to estimate the proportion of patients who experience one or more episodes of FN. The pooled, random effects meta-analysis estimate for the proportion of patients who experience one or more episodes of FN on docetaxel was 5.95% (95% CI 4.22-8.31) based on 13 studies, comprising 1609 patients. No significant differences were seen either between studies that permitted the use of prophylactic granulocyte colony-stimulating factors or between phase II and phase III trials.Evidence from randomised controlled trials suggests that the incidence of FN with docetaxel is around 6% and therefore an important factor to consider in the choice of the chemotherapy regimen.

Gestational trophoblastic neoplasia (GTN) is a rare but curable disease. The incidence in Europe and North America is nearly 1.5 per 1000 live births but much higher rates are reported from Africa and Asia. The majority of the patients respond to evacuation of the uterus plus or minus chemotherapy, however, occasional patients will die. Patients are categorised into low or high risk groups using a variety of scoring systems. A large number of regimens are used worldwide in the management of low risk GTN; there are reports of 14 different regimens in the English literature. The choice of the regimen is usually dependent on geographic location, prior training and current experience with the specific regimen. Regimens have significant differences in the route of administration, hospitalisation and side effects and so have a bearing on healthcare cost. Patients are therefore exposed to different regimens with the potential for different response rates and different side effect profiles.

One of the most important adverse effects of anthracyclines is cardiotoxicity. A well-informed decision on the use of anthracyclines in the treatment of different types of childhood cancer should be based on the available evidence on both antitumour efficacy and cardiotoxicity.

In the last 10 years the medical approach to platinum-resistant Non Small Cell Lung Cancer (NSCLC) has radically changed, passing from a lack of evidence of any primary treatment against the tumor, to the identification of chemotherapy or EGFR inhibitors as the gold standard for clinical practice. Eight randomized clinical trials support the evidence of efficacy of second-line treatments against NSCLC, and docetaxel, pemetrexed and erlotinib are the most effective options for clinical practice. However, many aspects remain still undefined: Can a treatment with docetaxel, pemetrexed or erlotinib be considered the gold standard for all patients with platinum-resistant NSCLC, and consequently should all patients be treated with at least one of these options? Are the benefits enough to justify the side effects observed with these chemotherapeutic options? Can a schedule be preferred to the others for either efficacy or safety profile? Can the new EGFR inhibitors be considered an innovation in the treatment of platinum-resistant NSCLC, and should they be used in all patients with platinum-resistant NSCLC? A systematic review of randomized clinical trials and a critical analysis of the results were performed with the aim to clarify the real meaning of medical treatments in advanced, platinum-resistant NSCLC.

Venous thromboembolism is one of the leading causes of morbidity and mortality in patients with cancer. Concerns have arisen regarding the risk of venous thromboembolism with the novel antiangiogenic agent bevacizumab, a recombinant humanized monoclonal antibody to vascular endothelial growth factor that is widely used in cancer treatment. Currently, the role of bevacizumab in venous thromboembolism is controversial.

Rash from epidermal growth factor receptor inhibitors is common and negatively impacts the quality of life of cancer patients. Published guidelines recommend holding cancer therapy if the rash is severe. Does this recommendation hinge solely on improving patients' quality of life, or does it also hinge on the prevention of a potentially fatal, cutaneous adverse event? In other words, do patients die from rashes from epidermal growth factor receptor inhibitors? To our knowledge, the latter question has never before been asked and answered in an evidence-based fashion. Therefore, we conducted a systematic review of the published, prospectively conducted clinical trial literature on epidermal growth factor receptor inhibitors. The primary aim was to determine whether rash-related death has ever been reported in such trials. Among 117 such trials, which included 8,998 cancer patients, the rate of rash development was >50%, as expected. However, there were no reported deaths from a rash. Although we cannot conclude that a rash-related death from this class of agents can never occur, this systematic review provides evidence-based guidance on how best to counsel cancer patients who develop a rash from an epidermal growth factor receptor inhibitor. It suggests that quality of life issues should remain at the forefront as cancer patients and health care providers make decisions about holding cancer therapy.

The incidence of cancer during pregnancy is increasing given the trend for women to postpone childbearing. Knowledge of the potential toxicity and teratogenicity of chemotherapy agents is crucial for patient counseling. Platinum derivatives are active against various malignancies that occur more frequently during pregnancy: melanoma, cervical and ovarian cancers, and lung cancer. The authors of this article performed a systematic review of reports documenting the use of platinum derivatives during pregnancy in the English literature from 1977 through January 2008. Forty-three pregnancies were described: 36 patients received cisplatin, 6 patients received carboplatin, and 1 patient received both drugs. Two fetal malformations occurred after in utero exposure to cisplatin, but the causative link between cisplatin administration and these malformations remains speculative. However, either detectable cisplatin levels or platinum-DNA adducts were observed in neonates who were exposed to platinum derivatives during the third trimester, providing evidence for a late-onset transplacental transfer of these drugs. The administration of platinum derivatives, although feasible during the second and third trimesters of pregnancy, raises concern regarding the transplacental transfer of these drugs in late pregnancy and has unknown short- and long-term effects.

Adverse effects of chemotherapy can be severe and can have a significant impact on a person's quality of life. With chemotherapy treatment increasingly administered in the ambulatory setting, there is a need for patients to be informed about effective self-care strategies to manage treatment adverse effects. Advice for patients needs to be based on evidence. This systematic review provides an overview of the intervention research in this area as well as an effectiveness review of nonpharmacologic (self-care) strategies evaluated in high-quality randomized controlled trials (RCTs).

Berberine is a isoquinoline alkaloid extracted from Chinese herbs such as Coptidis rhizome. In the past decade, there are more than 2 000 published papers studying the clinical application, pharmacodynamic mechanism and structure-activity relationship (SAR) of berberine and its derivatives, for treating tumor, diabetes, cardiavascellum disease, hyperlipemia, inflammation, bacterium and virus infection, cerebral ischemia trauma, mental disease, Alzheimer disease, osteoporosis, and so on. These results demonstrate that berberine has wide physiologic function and has great potential for structural modification as new drug lead. However, there is no systematic review about the study of berberine and its derivatives up to now. This paper is a systematic review of the research advances of berberine and its derevatives in clinical application, pharmacodynamic mechanisms, molecular pharmacology, absorption and metabolism, and SAR studies. The current review would provide some useful information for further study on structural modification of berberine for discovering new drug leads based on its pharmacodynamic mechanisms.

Chemotherapy is a well-established therapeutic approach for several malignancies, but its clinical efficacy is often limited by its related cardiotoxicity, which leads to cardiomyopathy, possibly evolving into heart failure. To detect cardiac damage, the adopted diagnostic approach is the estimation of left ventricular ejection fraction by echocardiography. This approach shows low sensitivity toward early prediction of cardiomyopathy, when the possibilities of appropriate treatments could still improve the patient's outcome. Cardiac troponins, however, show high diagnostic efficacy as early as 3 months before the clinical onset of cardiomyopathy. The increase in their concentrations is correlated with disease severity and may predict the new onset of major cardiac events during follow-up. Negative troponin concentrations may identify patients with a very low risk of cardiomyopathy (negative predictive value, 99%). Concerning cardiac natriuretic peptides, definitive evidence in regard to a diagnostic or prognostic role in predicting chemotherapy-induced cardiomyopathy is still lacking.

Granulopoiesis-stimulating factors, such as granulocyte-colony-stimulating factor (G-CSF) and granulocyte-macrophage-colony-stimulating factor (GM-CSF), are being used to prevent febrile neutropenia and infection in patients undergoing treatment for malignant lymphoma. The question of whether G-CSF and GM-CSF improve dose intensity, tumour response, and overall survival in this patient population has not been answered yet. Since the results from single studies are inconclusive, a systematic review was undertaken.

To evaluate the emerging role of immunomodulatory antibodies in cancer treatment. Antibodies (ipilimumab and tremelimumab) targeting cytotoxic T-lymphocyte antigen-4 (CTLA-4), an inhibitory molecule on T cells, represent the vanguard of these new drugs.
