Background Multiple myeloma is a haematological blood cancer of the bone marrow and is classified by the World Health Organisation (WHO) as a plasma cell neoplasm. In multiple myeloma, normal plasma cells transform into malignant myeloma cells and produce large quantities of an abnormal immunoglobulin called monoclonal protein or M protein. This ultimately causes multiple myeloma symptoms such as bone damage or kidney problems. The annual worldwide incidence of multiple myeloma is estimated to be 6 - 7/100,000 and accounts for 1% of all cancer...

BACKGROUND: The phosphatidyl inositol 3 kinase (PI3K), AKT and mammalian target of rapamycin (mTOR) signal transduction pathway is frequently de-regulated and activated in human cancer and is an important therapeutic target. AZD8835 is a PI3K inhibitor, with selectivity against PI3K α and δ isoforms, which is currently in Phase 1 clinical trials. 18F-Fluoro-deoxy-glucose positron emission tomography (18F-FDG PET) is a non-invasive pharmacodynamic imaging biomarker that has become an integral part of drug development...

Senescence is a universal barrier to immortalisation and tumorigenesis. As such, interest in the use of senescence-induction in a therapeutic context has been gaining momentum in the past few years; however, senescence and immortalisation remain underserved areas for drug discovery owing to a lack of robust senescence inducing agents and an incomplete understanding of the signalling events underlying this complex process. In order to address this issue we undertook a large-scale morphological siRNA screen for inducers of senescence phenotypes in the human melanoma cell line A375P...

Protein arginine methyltransferase 5 (PRMT5) plays critical roles in a wide variety of biological processes, including tumorigenesis. By screening a library of small chemical compounds, we identified eight compounds that selectively inhibit the PRMT5 enzymatic activity, with IC50 values ranging from 0.1 to 6 μM. Molecular docking simulation and site-directed mutagenesis indicated that identified compounds target the substrate-binding site in PRMT5. Treatment of lung cancer cells with identified inhibitors led to inhibition of the symmetrical arginine methylation of SmD3 and histones and the cellular proliferation...

Thioridazine is known to have anti-tumor effects by inhibiting PI3K/Akt signaling, which is an important signaling pathway in cell survival. However, thioridazine alone does not induce apoptosis in head and neck squamous cell carcinoma (AMC-HN4), human breast carcinoma (MDA-MB231), and human glioma (U87MG) cells. Therefore, we investigated whether combined treatment with thioridazine and curcumin induces apoptosis. Combined treatment with thioridazine and curcumin markedly induced apoptosis in cancer cells without inducing apoptosis in human normal mesangial cells and human normal umbilical vein cells (EA...

Chemotherapy is widely applied against various kinds of carcinoma. Generally, chemotherapeutic agents, such as Doxorubicin (DOX), Paclitaxel (PTX), 5-Fluorouracil (5-FU), Methotrexate (MTX), and Vinblastine (VLB) are combined with a view to maximizing their efficacy. Unfortunately, chemotherapeutics are indiscriminate and also kill normal healthy cells, resulting in serious side effects. This non-productive and destructive distribution of chemotherapeutics is regarded as one of the largest problems associated with chemotherapy...

Early detection and efficient treatment of cancer disease remains a drastic challenge in 21st century. Throughout the bulk of funds, studies, and current therapeutics, cancer seems to aggressively advance with drug resistance strains and recurrence rates. Nevertheless, nanotechnologies have indeed given hope to be the next generation for oncology applications. According to US National cancer institute, it is anticipated to revolutionize the perspectives of cancer diagnosis and therapy. With such success, nano-hybrid strategy creates a marvelous preference...

BACKGROUND: Lung adenocarcinoma can transform to small-cell lung cancer (SCLC) when resistance to tyrosine kinase inhibitors (TKIs) develops. This phenomenon has repeatedly been described in several case reports and small patient series. The characteristics and treatment outcomes of this population, however, have not been comprehensively reported. METHODS: We performed a systematic review of the published literature to obtain explorative information on the clinical and pathological features and prognosis of the reported cases...

Intraperitoneal administration of chemotherapeutics is expected for the treatment of peritoneally disseminated gastric cancer, because of poor migration of the drugs from the systemic circulation to the peritoneal cavity. In this study, for intraperitoneal delivery of cisplatin (CDDP), we developed a hyaluronan (HA)-based hybrid system in which CDDP-loaded HA nanogels were either physically encapsulated in or chemically conjugated to injectable HA hydrogels. Physical encapsulation enabled sustained release of HA nanogels from the HA hydrogel matrix for over a week...

Based on the structural similarity, herein, nucleoside analogue therapeutics were integrated into DNA strands through conventional solid-phase synthesis. By elaborately designing their sequences, floxuridine-integrated DNA strands were synthesized and self-assembled into well-defined DNA polyhedra with definite drug loading ratio as well as tunable size and morphology. As a novel drug delivery system, these drug-containing DNA polyhedra could ideally mimic the Trojan Horse to deliver chemotherapeutics into tumor cells and fight against cancer...

INTRODUCTION: Acellular dermal matrix (ADM) has gained widespread acceptance in immediate expander/implant reconstruction due to perceived benefits, including improved expansion dynamics and superior aesthetic results. Although previous investigators have evaluated its risks, few studies have assessed the impact of ADM on other outcomes, including patient-reported measures. METHODS: The Mastectomy Reconstruction Outcomes Consortium (MROC) Study used a prospective cohort design to evaluate patients undergoing post-mastectomy reconstruction from 10 centers and 58 participating surgeons between 2012 and 2015...

We present 3 cases of patients with castration-resistant prostate cancer and bone metastases treated with Ra, belonging to our prospective and multicenter ChoPET-Rad study. All patients underwent clinical, hematological, and biochemical monitoring between each Ra administration. Initial and follow-up F-fluorocholine PET/CT and Tc-biphosphonate bone scintigraphy were performed previously and after the third Ra administration. Both techniques correctly established the response to treatment, in agreement to the biochemical response, although differences in the disease expression (concordant and discordant patterns) were found because of the different radiotracer biodistribution and molecular information derived from them...

Purpose Increasing evidence indicates that statin use may reduce mortality from prostate cancer. In this work, we examined whether postdiagnosis statin use was associated with reduced cancer-specific mortality or all-cause mortality among patients with prostate cancer in Denmark. Material and Methods From nationwide Danish registries, we identified all patients with incident prostate adenocarcinoma from 1998 to 2011 and retrieved data on tumor and patient characteristics, drug use, and primary treatment. We defined postdiagnosis use (two or more prescriptions) of statins as a time-varying covariate with 1-year lag...

Peritonsillar abscess (PTA) is a common pathology in otolaryngology emergency. The treatment of PTA is usually bedside drainage or surgical removal of the tonsils (Quincy tonsillectomy) in combination with antibiotic treatment. However, patients with immune suppression might have a more difficult treatment course. Such difficulties may be further magnified within older patients. This case report will describe successful multi-modality treatment of two separate incidents of PTA developing in the context of immunosuppression...
