Few data exist regarding the systemic safety of intravitreal antivascular endothelial growth factor (anti-VEGF) monoclonal antibody (mAb).

A systematic literature review was performed to collect and review information on the clinical efficacy and safety of treatments for relapsed/refractory (R/R) mantle cell lymphoma (MCL), with a meta-analysis, if possible. PubMed, Embase, and the Cochrane Library were searched for studies published in English from January 1, 1997, to August 2, 2012. Conference proceedings, bibliographic reference lists of included articles, recent reviews, and ClinicalTrials.gov were searched for phase II to IV studies displaying results. Studies were included if they reported on patients with R/R MCL who were ineligible to receive high-dose chemotherapy with stem cell transplant. Studies of patients with several non-Hodgkin lymphoma subtypes were only included if they reported MCL outcomes separately. We identified 59 studies in R/R MCL. Forty distinct treatment regimens were evaluated. Thirty studies included more than 15 patients with R/R MCL. Six studies were comparative (including 5 randomized controlled trials [RCTs]); 53 were single-arm. There were no common treatments among the RCTs; therefore, a meta-analysis was not feasible. Thirty-one of 59 studies reported baseline data for patients with R/R MCL. Of the 30 studies with > 15 patients with R/R MCL, 30 reported overall response rate data, 14 reported progression-free survival (PFS), and 12 reported overall survival (OS). The small number of RCTs in R/R MCL precludes identifying an optimal treatment. Small sample sizes, infrequent reporting of OS and PFS, and limited information on patient characteristics made a comparison of results difficult. High-quality comparative studies of novel therapies that have the potential to demonstrate OS advantages in R/R MCL are needed.

Gastrointestinal mucositis is defined as inflammation and/or ulcers of the gastrointestinal tract occurring as a complication of chemotherapy and radiation therapy, and affects about 50% of all cancer patients.

Transarterial chemoembolization (TACE) and transarterial embolization (TAE) are commonly used as first-line treatment for patients with advanced hepatocellular carcinoma (HCC) and have been shown to improve overall survival (OS). However, there remain concerns regarding whether the benefit of the prolonged survival achieved with TACE is superior to the maximum cytotoxic effect of the associated chemotherapeutics. This systematic review aims to compare the efficiency of TACE and TAE based on randomized controlled trials (RCTs). MEDLINE, EMBASE, the Cochrane library, the Science Citation Index, and the Chinese National Knowledge Infrastructure databases were systematically searched through the end of April 2014. Risk ratios (RRs) and 95 % confidence intervals (CIs) were calculated. Meta-analysis of the RCTs was conducted to estimate the mortality and survival rate between the TACE and TAE groups. The analysis included five RCTs involving 582 patients. For all-cause mortality, TACE did not result in a statistically significant reduced incidence of adverse events than TAE with a pooled RR of 1.21 (95 % CI = 0.74-1.98, P = 0.16). In addition, 6-, 9-, 12-, 24-, and 36-month OS of the TACE group were not significantly higher than that of the TAE group (all P > 0.05). Interestingly, TACE resulted in a significantly higher rate of advanced events. The efficacy of TACE is not superior to TAE in advanced HCC patients. Moreover, TACE was associated with an increased rate of adverse events than TAE. Improved strategies are needed to reduce the risk of post-TACE complications.

Current therapy to slow disease progression in patients with neovascular age-related macular degeneration (AMD) often entails intra-vitreal injection of an anti-vascular endothelial growth factor (VEGF) agent, that begins with a three-month loading phase of four weekly injections followed by regular monthly visits with clinician-determined re-treatment. The effects of AMD on quality of life and visual function have been extensively reported in the literature, however, less is known about the burden imposed on patients by the arduous and often indefinite treatment schedule which habitually follows a diagnosis of wet AMD. To date, no systematic review has been conducted of research investigating patients' experiences of anti-VEGF treatment for AMD. A systematic search of the Embase, Medline, PsycINFO and PubMed electronic databases was undertaken to identify all studies between January 2004 and December 2013, published in the English language and involving human participants. A hand-search of an additional four journals was conducted. Ten articles were identified for inclusion in this review. A critical appraisal was undertaken using the Critical Appraisal Skills Programme Qualitative Research Checklist and the results synthesised to form a narrative review. Few studies to date have investigated patients' experiences of treatment for AMD. These studies have focused primarily on patients' experiences of the injection procedure with respect to pain and anxiety. Anticipated discomfort is often greater than actual discomfort experienced during intra-vitreal injection. However, different stages of the treatment procedure produce varying levels of patient discomfort. No one method of anaesthesia has consistently been shown to be more effective in reducing discomfort associated with treatment. Common reasons underlying patient apprehension surrounding treatment include the thought of having an injection, fear of losing eyesight and fear of the unknown. Whilst these studies have not been without their methodological limitations, they provide a platform for further exploration of the patient experience.

We performed a systematic review and comparative meta-analysis of cardiovascular toxicities associated with sunitinib, axitinib, cediranib or regorafenib; oral multi tyrosine kinase inhibitors.

High human equilibrative nucleoside transporter 1 (hENT1)-expression has shown a survival benefit in pancreatic cancer patients treated with gemcitabine in several studies. The aim of this systematic review was to summarize the results and try to assess the predictive value of hENT1 for determining gemcitabine outcome in pancreatic cancer. Relevant articles were obtained from PubMed, Embase and Cochrane databases. Studies evaluating hENT1-expression in pancreatic tumor cells from patients treated with gemcitabine were selected. Outcome measures were overall survival, disease-free survival (DFS), toxicity and response rate. The database searches identified 10 studies that met the eligibility criteria, and a total of 855 patients were included. Nine of 10 studies showed a statistically significant longer overall survival in univariate analyses in patients with high hENT1-expression compared to those with low expression. In the 7 studies that reported DFS as an outcome measure, 6 had statistically longer DFS in the high hENT1 groups. Both toxicity and response rate were reported in only 2 articles and it was therefore hard to draw any major conclusions. This review provides evidence that hENT1 is a predictive marker for pancreatic cancer patients treated with gemcitabine. Some limitations of the review have to be taken into consideration, the majority of the included studies had a retrospective design, and there was no standardized scoring protocol for hENT1-expression.

We conducted a meta-analysis of randomized trials of ranibizumab for age-related macular degeneration (AMD) to elucidate systemic vascular risk.

Bortezomib is administered for a finite course; thus, patients might remain sensitive to bortezomib-based therapy at relapse. We report a meta-analysis of bortezomib-based retreatment in relapsed/refractory myeloma.

Caffeic acid phenethyl ester (CAPE), an active component of propolis, has been attracting the attention of different medical and pharmaceutical disciplines in recent years because of its antioxidant, anti-inflammatory, antiproliferative, cytotoxic, antiviral, antifungal, and antineoplastic properties. One of the most studied organs for the effects of CAPE is the kidney, particularly in the capacity of this ester to decrease the nephrotoxicity induced by several drugs and the oxidative injury after ischemia/reperfusion (I/R). In this review, we summarized and critically evaluated the current knowledge regarding the protective effect of CAPE in nephrotoxicity induced by several special medicines such as cisplatin, doxorubicin, cyclosporine, gentamycin, methotrexate, and other causes leading to oxidative renal injury, namely, I/R models and senility.

Despite complex surgical and systemic therapies epithelial ovarian cancer has a poor prognosis. A small quantity of tumorigenic cells termed cancer stem cells (CSC) are responsible for the development of chemoresistance and high rates of recurrence.

Anti-angiogenic therapy targeted at vascular endothelial growth factor (VEGF) is now used to treat several types of cancer. We did a systematic review of randomized controlled trials (RCTs) to summarize the adverse effects of vascular endothelial growth factor inhibitors (VEGFi), focusing on those with vascular pathogenesis.

Platinum-based therapy, including cisplatin, carboplatin and/or oxaliplatin, is used to treat a variety of paediatric malignancies. Unfortunately, one of the most important adverse effects is the occurrence of hearing loss or ototoxicity. In an effort to prevent this ototoxicity, different otoprotective medical interventions have been studied. This review is an update of a previously published Cochrane review.

Non-steroidal antiandrogens and castration are the main therapy options for advanced stages of prostate cancer. However, debate regarding the value of these treatment options continues.

Clinical decision rules (CDRs) have sought to identify the few children with chemotherapy-induced febrile neutropenia (FN) really at risk of severe infection to reduce the invasive procedures and costs for those at low risk. Several reports have shown that most rules do not perform well enough to be clinically useful. Our objective was to analyze the derivation methods and validation procedures of these CDRs.

Platinum-based therapy, including cisplatin, carboplatin or oxaliplatin, or a combination of these, is used to treat a variety of paediatric malignancies. Unfortunately, one of the most important adverse effects is the occurrence of hearing loss or ototoxicity. In an effort to prevent this ototoxicity, different platinum infusion durations have been studied.

A systematic review and meta-analysis of fatigue and hepatic adverse events associated with lapatinib use in solid tumor patients were performed.

To review the available published data regarding the incidence, mechanisms of pathogenesis, clinical presentations and management of pneumonitis caused by anti-cancer treatments (radiotherapy (RT) and systemic agents) that are included in the guidelines of the treatment of breast cancer (BC) and address the issues on the current grading classification of pneumonitis. A literature search was performed between July and October 2013 using PubMed for papers published from January 1989 to October 2013. Any clinical trial, case report, case series, meta-analysis or systematic review that reported on pulmonary toxicity of any BC therapeutic modality was included (only papers published in English). Most of anticancer treatments currently used in the management of BC may induce some degree of pneumonitis that is estimated to have an incidence of 1-3 %. There is an obvious distinction between chemotherapy- and targeted treatment-related lung toxicity. Moreover, the current classification of pneumonitis needs to be modified as there is a clear diversity in grade 2. As pneumonitis is relatively common and reported as side effect of new anticancer agents, physicians need to be aware of the clinical and radiological manifestations of drug- and RT-induced toxicities in patients with BC. A key recommendation is the subdivision of grade 2 cases to two subgroups. We provide an algorithm, along with real life cases as managed in the breast Unit of Royal Marsden Hospital, with the aim to guide physicians in managing all possible eventualities that may come across in clinical practise.

Post-lumbar puncture headaches (PLPHs) are a known complication of lumbar puncture procedures. Children undergoing treatment for cancer often undergo multiple lumbar punctures, placing them at increased risk for PLPHs. There are currently no guidelines for the prevention or management of PLPHs in children. A team was therefore assembled to conduct a systematic review of the evidence in relationship to PLPHs in the pediatric population. Clinical questions were developed and used to guide the literature review. Twenty-four articles were deemed appropriate for use and were evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Based on the review of evidence, strong recommendations are made for the use of smaller needle sizes and for the use of pencil point needles during lumbar puncture procedures. Weak recommendations are made for needle orientation and positioning following the procedure as well as for interventions used to treat PLPHs once they occur. There is a need for additional, pediatric-specific studies to further examine the issue of PLPH prevention and treatment.

We performed a systematic review and meta-analysis of thyroid function abnormalities associated with seven vascular endothelial growth factor receptor (VEGFR) targeted tyrosine kinase inhibitors (sorafenib, sunitinib, axitinib, cediranib, pazopanib, regorafenib and vandetanib). Eligible studies included randomized Phase II and III trials of patients with solid tumors on sorafenib OR sunitinib OR axitinib OR cediranib OR pazopanib OR regorafenib OR vandetanib; describing events of hypothyroidism or hyperthyroidism. Our search strategy yielded 195 potentially relevant citations on the seven agents from Pubmed/Medline, CENTRAL Cochrane registry and ASCO meeting library. After exclusion of ineligible studies, a total of 12 clinical trials were considered eligible for the meta-analysis, including six sunitinib studies, four cediranib studies and two axitinib studies. Patients treated with these agents had a significantly increased risk of all-grade hypothyroidism and the relative risk (RR) of all-grade hypothyroidism was 3.59 (95% CI = 2.40-5.38, p ≤ 0.0001). Exploratory subgroup analysis showed no effect of tumor types or agent used on the RR of hypothyroidism. Our meta-analysis has demonstrated that these three agents are associated with a significantly increased risk of all-grade hypothyroidism; with no difference - on subgroup analysis - between sunitinib and cediranib. Clinicians should be aware of these risks and perform regular thyroid function monitoring.
