INTRODUCTION: It is 40 years since the initial documentation of the efficacy of bacille Calmette-Guérin (BCG) in the management of non-muscle invasive bladder cancer (NMIBC) and probably an opportune a time as any to retrace the origins of this development and to reflect on the progress that has occurred on the use of immune modifiers in the treatment of NMIBC. MATERIALS AND METHODS: A PubMed search for publications on the history of BCG was conducted, and those related to the development of the vaccine for protection against tuberculosis as well as those published in the last 40 years related to its use for treatment for NMIBC were selected for review...

BACKGROUND: In patients with chronic disease, many health care professionals are involved during treatment and follow-up. This leads to fragmentation that in turn may lead to suboptimal care. Shared care is a means to improve the integration of care delivered by various providers, specifically primary care physicians (PCPs) and specialty care professionals, for patients with chronic disease. The use of information technology (IT) in this field seems promising. OBJECTIVE: Our aim was to systematically review the literature regarding the effectiveness of IT-supported shared care interventions in chronic disease in terms of provider or professional, process, health or clinical and financial outcomes...

Ovarian cancer (OC) is the second most common and the most lethal of the gynecological malignancies. Currently, there exists no effective screening tool for OC. MicroRNAs (miRNAs) are endogenous 18-23 nucleotide non-coding RNAs that refine gene expression. MiRNAs have been found to be aberrantly expressed in OC tumor tissue as well as detectable in biological fluids such as the blood, urine, and ascites and have been proposed as biomarkers and therapeutic targets for OC. Areas covered: This review summarizes the current knowledge regarding the application of miRNAs as diagnostic, prognostic, and predictive biomarkers in OC...

Gliomas are brain-born tumors with devastating impact on their brain microenvironment. Novel approaches employ multiple combinations of chemical compounds in synthetic hybrid molecules to target malignant tumors. Here, we report on the chemical hybridization approach exemplified by artesunic acid (ARTA) and naturally occurring triterpene betulinic acid (BETA). Artemisinin derived semisynthetic compound artesunic acid (ARTA) and naturally occurring triterpene BETA were used to synthetically couple to the hybrid compound termed 212A...

The medical burden of heart failure (HF) has spurred interest in clinicians and scientists to develop therapies to restore the function of a failing heart. To advance this agenda, the National Heart, Lung, and Blood Institute (NHLBI) convened a Working Group of experts from June 2 to 3, 2016, in Bethesda, Maryland, to develop NHLBI recommendations aimed at advancing the science of cardiac recovery in the setting of mechanical circulatory support (MCS). MCS devices effectively reduce volume and pressure overload that drives the cycle of progressive myocardial dysfunction, thereby triggering structural and functional reverse remodeling...

The Vitamin D receptor (VDR) expressed in normal breast tissue and breast tumors has been suggested as a new prognostic biomarker in breast cancer (BC). Besides, increasing evidence supports the view that the detection of circulating tumor cells (CTCs) predicts outcome in early and metastatic BC. Consequently, an evaluation of VDR expression in the CTCs of BC patients may allow optimization of their treatment. As an attempt to profile and subtype the CTCs of metastatic patients, we established an innovative fluorescence technique using nine BC cell lines to visualize, define, and compare their individual VDR status...

Ovarian cancer is the seventh most common cancer in women. The therapeutic approach provides for an appropriate integration between surgery and chemotherapy. Surgery is an important step for diagnosis, staging and therapy, aiming at the complete cytoreduction of all macroscopic visible disease. At the moment, adjuvant and first-line chemotherapy has as a standard the carboplatin-paclitaxel combination. Further, the addition of bevacizumab in the advanced stage (IIIB-IV) is strongly recommended. Despite the initial effectiveness, however, 70-80% of patients develop relapsed disease within the first two years and require subsequent treatment lines that have palliative, rather than curative purposes and that seek to reach a chronic state for the disease...

Innovative therapies for solid tumors are urgently needed. Recently, therapies that harness the host immune system to fight cancer cells have successfully treated a subset of patients with solid tumors. These responses have been strong and durable but observed in subsets of patients. Work from our group and others has shown that epigenetic therapy, specifically inhibiting the silencing DNA methylation mark, activates immune signaling in tumor cells and can sensitize to immune therapy in murine models. Here we show that colon and ovarian cancer cell lines exhibit lower expression of transcripts involved in antigen processing and presentation to immune cells compared to normal tissues...

Phase I oncology trials are designed to identify a safe dose with an acceptable toxicity profile. In traditional phase I dose-finding design, the dose is typically determined based on the probability of severe toxicity observed during the first treatment cycle. The recent development of molecularly targeted agents and cancer immunotherapies call for new innovations in phase I designs, because of prolonged treatment cycles often involved. Various phase I designs using toxicity and efficacy endpoints from multiple treatment cycles have been developed for these new treatment agents...

Taxane-based therapy provides a survival benefit in patients with metastatic prostate cancer, yet the median survival is less than 20 months in this setting due in part to taxane-associated resistance. Innovative strategies are required to overcome chemoresistance for improved patient survival. Here, NanoOrl, a new experimental nanoparticle formulation of the FDA-approved drug, orlistat, was investigated for its cytotoxicity in taxane-resistant prostate cancer utilizing two established taxane-resistant (TxR) cell lines...

Colorectal cancer (CRC) results from progressive accumulation of genetic and epigenetic alterations. IFN signaling defects play an important role in the carcinogenesis process, in which the inability of IFN transcription regulatory factors (IRFs) to access regulatory sequences in IFN-stimulated genes (ISGs) in tumors and in immune cells may be pivotal. We reported that low-dose combination of two FDA-approved epidrugs, azacytidine (A) and romidepsin (R), with IFNa2 (ARI) hampers the aggressiveness of both CRC metastatic and stem cells in vivo and triggers immunogenic cell death signals that stimulate dendritic cell (DC) function...

Anticancer immunotherapy has undergone a long evolving journey for decades, and has been dramatically applied to mainstream treatments in oncology in recent 5 years. This progress represents an advanced milestone following cytotoxic medicine and targeted therapy. Cellular immunity plays a pivotal role in the immune responses of hosts to tumor antigens. Such immunity is notably suppressed during neoplastic progression due to immuno-editing processes. Cellular immunity can also be selectively re-activated to combat malignancies while exploiting the advantages of contemporary scientific breakthroughs in molecular immunology and genetic engineering...

Neuroblastoma, the commonest paediatric extra-cranial tumour, remains a leading cause of death from cancer in children. There is an urgent need to develop new drugs to improve cure rates and reduce long-term toxicity and to incorporate molecularly targeted therapies into treatment. Many potential drugs are becoming available, but have to be prioritised for clinical trials due to the relatively small numbers of patients. Areas covered: The current drug development model has been slow, associated with significant attrition, and few new drugs have been developed for neuroblastoma...

Mimicry of bioactive conformations is critical for peptide-based medicinal chemistry because such peptidomimetics may augment stability, enhance affinity, and increase specificity. Azapeptides are peptidomimetics in which the α-carbon(s) of one or more amino acid residues are substituted by nitrogen. The resulting semicarbazide analogues have been shown to reinforce β-turn conformation through the combination of lone pair-lone pair repulsion of the adjacent hydrazine nitrogen and urea planarity. Substitution of a semicarbazide for an amino amide residue in a peptide may retain biological activity and add benefits such as improved metabolic stability...
