Recent data suggest that fractures might affect quality of life and survival in early breast cancer patients. Bisphosphonates are effective in treatment and prevention of cancer treatment-induced bone loss, but their value in the prevention of fractures is still investigational. Our aim was to evaluate the fracture rate in breast cancer patients receiving adjuvant bisphosphonates compared with those receiving no treatment or placebo.
2882. Topical imiquimod or fluorouracil therapy for basal and squamous cell carcinoma: a systematic review.
To conduct a systematic review to determine clearance rates and adverse effects of topical imiquimod or fluorouracil therapy in the treatment of nonmelanoma skin cancers such as basal (BCC) and squamous cell carcinoma (SCC), and to develop recommendations for the use of topical imiquimod or fluorouracil to treat BCC and SCC.

In hypermetabolic situations, glutamine is intensively used by rapidly dividing cells such as enterocytes, lymphocytes, and fibroblasts as nitrogen source and/or alternative energy fuel. It is hypothesized that in cancer patients the increased glutamine demands of the host increase the capacity of endogenous production resulting in a strong glutamine deprivation with detrimental effects on organ functions. In long-term periods of cancer cachexia, an adequate nutrition support including glutamine can essentially contribute to cover glutamine needs and, thus, to spare energy reserves of the host and to retard severe complications such as multi-organ failure. Due to the early in vitro knowledge that cancer cells preferably consume glutamine, oncologists often refuse to supply glutamine to the tumor-bearing host to avoid any potential risk. An objective evaluation whether supplemental glutamine supports tumor growth in vivo is, however, still lacking.
2885. Novel VEGF signalling inhibitors: how helpful are biomarkers in their early development?
The development of vascular endothelial growth factor (VEGF) inhibitors of tumour angiogenesis can only be described as prolific. It is therefore interesting to speculate which will reach the clinic. Of course, the most effective agents will succeed, but how is effectiveness measured? When presented with a summary of competitive compounds, it can be difficult to discriminate between their potency on target, toxicity and response rates.
2886. Levonorgestrel intrauterine system for endometrial protection in women with breast cancer on adjuvant tamoxifen.
Adjuvant tamoxifen reduces the risk of breast cancer recurrence in women with estrogen receptor-positive breast cancer. Tamoxifen also increases the risk of postmenopausal bleeding, endometrial hyperplasia, polyps, and endometrial cancer. The levonorgestrel-releasing intrauterine system (LNG-IUS) causes profound endometrial suppression. This systematic review considered the evidence that the LNG-IUS prevents the development of endometrial pathology in women taking tamoxifen as adjuvant endocrine therapy for breast cancer.

The use of anthracycline chemotherapy is limited by the occurrence of cardiotoxicity. To prevent this cardiotoxicity, different anthracycline dosage schedules have been studied.
2888. Risk of bleeding with vascular endothelial growth factor receptor tyrosine-kinase inhibitors sunitinib and sorafenib: a systematic review and meta-analysis of clinical trials.
Sunitinib and sorafenib are oral vascular endothelial growth factor receptor (VEGFR) tyrosine-kinase inhibitors used in various cancers. Bleeding has been described with these agents, although the overall risk remains unclear. We did a systematic review and meta-analysis to calculate the incidence and relative risk associated with use of sunitinib and sorafenib.

The aim of the present study was to scrutinize the evidence on the use of acupoint stimulation for managing therapy-related adverse events in breast cancer. A comprehensive search was conducted on eight English and Chinese databases to identify clinical trials designed to examine the efficacy of acupressure, acupuncture, or acupoint stimulation (APS) for the management of adverse events due to treatments of breast cancer. Methodological quality of the trials was assessed using a modified Jadad scale. Using pre-determined keywords, 843 possibly relevant titles were identified. Eventually 26 papers, 18 in English and eight in Chinese, satisfied the inclusion criteria and entered the quality assessment stage. The 26 articles were published between 1999 and 2008. They assessed the application of acupoint stimulation on six disparate conditions related to anticancer therapies including vasomotor syndrome, chemotherapy-induced nausea and vomiting, lymphedema, post-operation pain, aromatase inhibitors-related joint pain and leukopenia. Modalities of acupoint stimulation used included traditional acupuncture, acupressure, electroacupuncture, and the use of magnetic device on acupuncture points. Overall, 23 trials (88%) reported positive outcomes on at least one of the conditions examined. However, only nine trials (35%) were of high quality; they had a modified Jadad score of 3 or above. Three high quality trials revealed that acupoint stimulation on P6 (NeiGuang) was beneficial to chemotherapy-induced nausea and vomiting. For other adverse events, the quality of many of the trials identified was poor; no conclusive remarks can be made. Very few minor adverse events were observed, and only in five trials. APS, in particular acupressure on the P6 acupoint, appears beneficial in the management of chemotherapy-induced nausea and vomiting, especially in the acute phase. More well-designed trials using rigorous methodology are required to evaluate the effectiveness of acupoint stimulation interventions on managing other distress symptoms.

Mistletoe is often used as a complementary approach in oncology. Despite experimental anti-tumour effects and several reviews there remains controversy about its clinical role.
2891. A systematic review of the anticancer properties of berberine, a natural product from Chinese herbs.
Natural products represent a rich reservoir of potential small chemical molecules exhibiting antiproliferation and anticancer properties. An example is berberine, a protoberberine alkaloid widely distributed in medical plants used in traditional Chinese prescriptions. Recent advances have shown that berberine exerts anticancer activities both in vitro and in vivo through different mechanisms. Berberine shows inhibitory effects on the proliferation and reproduction of certain tumorigenic microorganisms and viruses, such as Heliobacter pylori and hepatitis B virus. Transcriptional regulation of some oncogene and carcinogenesis-related gene expression and interaction with both DNA and RNA are also well documented. Besides, berberine is a broad spectrum enzyme inhibitor, which affects N-acetyltransferase, cyclooxygenase-2, and topoisomerase activities and gene/protein expression. These actions, together with the regulation of reactive oxygen species production, mitochondrial transmembrane potential, and nuclear factor-kappaB activation might underlie its antiproliferative and proapoptotic effects. More importantly, the suppression of tumor growth and metastasis, the beneficial application in combined medication, and the improvement of multidrug resistance both in vivo and in vitro clearly show its potential as an alternative medicine for tumor chemotherapy.

Clinical experience suggests that children with cancer experience multiple symptoms as a result of their disease and/ or its treatment. These symptoms may have a negative impact on children's ability to function and on their quality of life. No systematic review has summarized the findings from studies that assessed multiple symptoms in these patients. The purposes of this article are to summarize the findings from the studies of multiple symptoms in pediatric oncology patients and to describe directions for future research. Although there has been a recent increase in the studies of the multiple symptoms in pediatric cancer patients, only 9 studies were found that met the inclusion criteria for this review. Thus, little is known about the relationships between demographic and clinical characteristics and the occurrence of multiple symptoms. Additional research is warranted on the prevalence and impact of multiple symptoms, particularly among homogeneous samples of patients. Future directions for symptom studies in pediatric oncology include symptom cluster research and the search for biological bases for the untoward effects of cancer treatment.
2893. Potential benefits of intermittent androgen suppression therapy in the treatment of prostate cancer: a systematic review of the literature.
The well-known side-effect profile of androgen-deprivation therapy (ADT) has significant quality-of-life (QoL) implications. Intermittent androgen deprivation (IAD) alternates androgen blockade with treatment cessation to allow hormonal recovery between treatment cycles, thus potentially improving tolerability and QoL.
2894. Risk of high-grade skin rash in cancer patients treated with cetuximab--an antibody against epidermal growth factor receptor: systemic review and meta-analysis.
Cetuximab, a chimeric antibody against epidermal growth factor receptor has emerged as an effective therapy for advanced colorectal cancer (CRC) and head-neck cancer. However, severe skin toxicity may limit its use. Its efficacy in the treatment of other cancers is also undergoing extensive investigation. We performed a systemic review and meta-analysis of published clinical trials to quantify the overall incidence and risk of severe skin rash.

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), developed for patients with advanced non-small cell lung cancer (NSCLC), give modest results similar to those with chemotherapy. There is evidence of a greater survival benefit from TKIs in patients with certain molecular and clinical features, but results are conflicting. To assess the role of these factors in predicting TKI efficacy, a pooled analysis was performed on data from randomized trials in NSCLC.
2896. Percutaneous ethanol injection or percutaneous acetic acid injection for early hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the fifth most common global cancer. When HCC is detected early, interventions such as percutaneous ethanol injection (PEI), percutaneous acetic acid injection (PAI), and radiofrequency thermal ablation (RFTA) have curative potential and represent low invasive alternatives to surgery. The role of PEI or PAI has not been addressed in a systematic review.
2897. Anthracyclines in early-stage breast cancer: is it the end of an era?
Anthracycline regimens have been the mainstay of adjuvant care in breast cancer for >20 years. A growing body of clinical experience has uncovered an unacceptable rate of significant cardiac and leukomogenic toxicities. A systematic review of the literature was performed highlighting anthracycline- and nonanthracycline-based adjuvant regimens. The published data suggest that nonanthracycline alternatives are less toxic than anthracycline-containing regimens and equally, if not more, efficacious. Molecular predictors, such as human epidermal growth factor receptor 2 and topoisomerase II alpha, are further refining the optimal role of anthracyclines. With these new advances, the current role of anthracycline-based chemotherapy in early-stage breast cancer demands re-examination.
2898. Should the treatment of peritoneal carcinomatosis by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy still be regarded as a highly morbid procedure?: a systematic review of morbidity and mortality.
: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been offered in many institutions worldwide since the 1990s. Despite its existence of more than 10 years, this treatment has received heavy criticism for its morbidity and mortality rates. This consequentially resulted in a lack of randomized trials being conducted and translates into a lack of the most reliable form of scientific evidence in clinical research, hence limiting its general acceptance.
2899. Safety of multi-targeted kinase inhibitors as monotherapy treatment of cancer: a systematic review of the literature.
To identify potential safety profiles for small molecule multi-targeted kinase inhibitors for the treatment of advanced cancer.
