BACKGROUND: Lapatinib is an oral small molecule tyrosine kinase epidermal growth factor receptor-1/HER2 inhibitor that crosses the blood-brain barrier and is active against central nervous system (CNS) metastases. Cabazitaxel is a taxoid that is effective against taxane-resistant metastatic breast cancer (MBC) and has distinguished itself by its ability to cross the blood-brain barrier. The present phase II study (ClinicalTrials.gov identifier, NCT01934894) evaluated the combination of these agents to treat HER2+ MBC patients with CNS metastases...

Hormone receptor-positive breast cancer is commonly treated with endocrine therapy; however, overtime cancer cells can develop endocrine resistance. This review aims to document combination therapy and sequential therapy in the use of endocrine agents and targeted agents. By conducting two systematic searches using 4 databases: Cochrane Library, MEDLINE, EMBASE, and Web of Science. A total of 26 studies that covered combination therapy were obtained and included for the review. 14 were phase III documenting combinations of mechanistic target of rapamycin (mTOR), phosphoinositide-3-kinase (PI3K), vascular endothelial growth factor receptor (VEGFR), human epidermal growth factor receptor 2 (HER2), and cyclin dependent kinase 4/6 (CDK4/6) inhibitors...

The Global Genomic Medicine Collaborative, a multinational coalition of genomic and policy experts working to implement genomics in clinical care, considers pharmacogenomics to be among the first areas in genomic medicine that can provide guidance in routine clinical practice, by linking genetic variation and drug response. Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe life-threatening reactions to medications with a high incidence worldwide. Genomic screening prior to drug administration is a key opportunity and potential paradigm for using genomic medicine to reduce morbidity and mortality and ultimately eliminate one of the most devastating adverse drug reactions...

Drug hypersensitivity may manifest ranging from milder skin reactions (e.g., maculopapular exanthema and urticaria) to severe systemic reactions, such as anaphylaxis, drug reactions with eosinophilia and systemic symptoms (DRESS)/drug-induced hypersensitivity syndrome (DIHS), or Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). Current pharmacogenomic studies have made important strides in the prevention of some drug hypersensitivity through the identification of relevant genetic variants, particularly for genes encoding drug-metabolizing enzymes and human leukocyte antigens (HLAs)...

Dysregulation in the expression of microRNAs (miRNAs), single stranded RNAs which regulate gene expression, has been associated with diseases such as Stevens-Johnson syndrome (SJS) / toxic epidermal necrolysis (TEN), although their cellular origin has not been explored. Thus, the focus of this work was to study expression patterns of reported miRNAs involved in T - cell activation following drug-specific stimulation in peripheral blood mononuclear cells (PBMCs) and drug specific CD4+ T-cell clones (TCC) from patients with different cutaneous manifestations of delayed-type drug hypersensitivity reactions...

BACKGROUND: Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are mucocutaneous hypersensitivity reactions, usually to drugs or their metabolites. TEN is the most severe involving greater than 30% of the total body surface area (TBSA). Management of these patients usually benefits from a large multidisciplinary team for both wound and medical management. Treatment of these patients varies between centers and physicians and there is lack of a standardized treatment protocol in the medical literature...

Photosensitization is severe dermatitis or oxidative/chemical changes in the epidermal tissues activated by the light-induced excitation of molecules within the tissue. It is a series of reactions mediated through light receptors and is more common when the plant-produced metabolites are heterocyclic/polyphenols in nature. The areas affected are exposed body parts and mostly non-pigmented areas with least ultraviolet protection. Similarly, cellular alteration also occurs in the affected animal's dermal tissues and body parts and grazing animals by the accumulation and activation of photodynamic molecules...

Sohel M Julovi, Janet L Martin, Robert C Baxter
Triple-negative breast cancer (TNBC) typically has a worse outcome than other breast cancer subtypes, in part owing to a lack of approved therapeutic targets or prognostic markers. We have previously described an oncogenic pathway in basal-like TNBC cells, initiated by insulin-like growth factor binding protein-3 (IGFBP-3), in which the epidermal growth factor receptor (EGFR) is transactivated by sphingosine-1-phosphate (S1P) resulting from sphingosine kinase (SphK)-1 activation. Oncogenic IGFBP-3 signaling can be targeted by combination treatment with the S1P receptor modulator and SphK inhibitor, fingolimod, and the EGFR kinase inhibitor, gefitinib (F + G)...

Chemoprevention represents an attractive modality against colorectal cancer (CRC) although widespread clinical implementation of promising agents (e.g. aspirin/NSAIDS) have been stymied by both suboptimal efficacy and concerns over toxicity. This highlights the need for better agents. Several groups, including our own, have reported that the over-the-counter laxative polyethylene glycol (PEG) has remarkable efficacy in rodent models of colon carcinogenesis. In this study, we undertook the first randomized human trial to address the role of PEG in prevention of human colonic neoplasia...

Oxcarbazepine is an antiepileptic drug (AED) commonly used as a first-line treatment option for focal epilepsy. Several AEDs, including carbamazepine, oxcarbazepine, and phenytoin are associated with various delayed-hypersensitivity reactions such as drug reaction with eosinophilia and systemic symptoms, Stevens-Johnson syndrome, or toxic epidermal necrolysis. The Food and Drug Administration-approved label for oxcarbazepine currently presents information regarding a pharmacogenomic association with the HLA antigen allele HLA-B*15:02 and hypersensitivity reactions in certain ancestry groups with a high incidence of this allele...

Inflammatory dermatoses encompass a variety of histologic patterns that affect different portions of the skin. In spongiotic, psoriasiform, lichenoid, pityriasiform, and blistering disorders, there are predominately epidermal and junctional activities with variable superficial dermal inflammation. Hypersensitivity reactions can show either epidermal or mostly dermal changes depending on whether the exposure of the exogenous allergen occurs through an external or internal route, respectively. Exceptions include erythema multiforme and Stevens-Johnson syndrome/toxic epidermal necrolysis, where the etiology is often due to infection or ingested medications, but the histologic features are almost exclusively confined to the epidermis and dermoepidermal junction...

Nasopharyngeal carcinoma (NPC) is a type of head and neck cancers with poor prognosis. Despite that platinum-based chemotherapy concurrent with radiotherapy have made great achievements for the treatment of NPC, the therapeutic reaction and toxicity varies dramatically among individuals. Apigenin (API), a naturally occurring plant flavone, is considered to have anti-cancer effect. Cetuximab (CET), a well known epidermal growth factor receptor (EGFR) inhibitor, is widely used in various cancers, especially head and neck cancers...
