REVIEW
Patricia Tai, Joseph Au
There are many different types of skin tumors in the World Health Organization (WHO) classification. The natural course and treatment varies according to the histological type. This review summarizes clinical experience for treatment decision. Contemporary radiotherapy and systemic therapy are improving. Landmark studies for basal cell and Merkel cell carcinomas (MCC) trigger further research and impetus for improving treatment outcome. Avelumab, nivolumab, pembrolizumab, ipilimumab appear to be promising for treatment of advanced MCCs and adjuvant trials are underway...

REVIEW
Hua Wang, David J Mooney
The past decade has witnessed the accelerating development of immunotherapies for cancer treatment. Immune checkpoint blockade therapies and chimeric antigen receptor (CAR)-T cell therapies have demonstrated clinical efficacy against a variety of cancers. However, issues including life-threatening off-target side effects, long processing times, limited patient responses and high cost still limit the clinical utility of cancer immunotherapies. Biomaterial carriers of these therapies, though, enable one to troubleshoot the delivery issues, amplify immunomodulatory effects, integrate the synergistic effect of different molecules and, more importantly, home and manipulate immune cells in vivo...

REVIEW
Michiel Remmerie, Veerle Janssens
Type II endometrial carcinomas (ECs) are responsible for most endometrial cancer-related deaths due to their aggressive nature, late stage detection and high tolerance for standard therapies. However, there are no targeted therapies for type II ECs, and they are still treated the same way as the clinically indolent and easily treatable type I ECs. Therefore, type II ECs are in need of new treatment options. More recently, molecular analysis of endometrial cancer revealed phosphorylation-dependent oncogenic signalling in the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) pathways to be most frequently altered in type II ECs...

The past few decades have witnessed widespread research to challenge carcinogenesis; however, it remains one of the most important health concerns with the worst prognosis and diagnosis. Increasing lines of evidence clearly show that the rate of cancer incidence will increase in future and will create global havoc, designating it as an epidemic. Conventional chemotherapeutics and treatment with synthetic disciplines are often associated with adverse side effects and development of chemoresistance. Thus, discovering novel economic and patient friendly drugs that are safe and efficacious is warranted...

Cancer Stem Cells (CSCs) or Tumor-Initiating Cells (TICs) are a small sub-population of cells within the tumor, able to give chemio- and radio-resistance and cause the onset of metastasis and the presence of relapses; for these reasons, they are recently becoming a potential target for anticancer therapy. One of the main characteristics of these cells is the self-renewal through the capability of modulating different molecular signalling pathways, including Wnt/β-Catenin, Sonic Hedgehog and Notch pathways...

BACKGROUND: Among the numerous bio-responsive polymeric drug delivery systems developed recently, redox-triggered release of molecular payloads have gained great deal of attention, especially in the field of anticancer drug delivery. In most cases, these systems rely on disulfide bonds located either in the matrix cross-link, or in auxiliary chains to achieve stimuli-responsive drug release. These bonds keep their stability in extracellular environments, yet, rapidly break by thiol-disulfide exchange reactions in the cytosol, due to the presence of greater levels of glutathione...

Multidrug resistance (MDR) is a major hurdle which must be overcome to effectively treat cancer. ATP-binding cassette transporters (ABC transporters) play pivotal roles in drug absorption and disposition, and overexpression of ABC transporters has been shown to attenuate cellular/tissue drug accumulation and thus increase MDR across a variety of cancers. Overcoming MDR is one desired approach to improving the survival rate of patients. To date, a number of modulators have been identified which block the function and/or decrease the expression of ABC transporters, thereby restoring the efficacy of a range of anticancer drugs...

Substantial efforts are underway for prevention of early stages or recurrence of colorectal cancers (CRC) or new polyp formation by chemoprevention strategies. Several epidemiological, clinical and preclinical studies to date have supported the chemopreventive potentials of several targeted drug classes including non-steroidal anti-inflammatory drugs (NSAIDs) (aspirin, naproxen, sulindac, celecoxib, and licofelone), statins and other natural agents-both individually, and in combinations. Most preclinical trials although were efficacious, only few agents entered clinical trials and have been proven to be potential chemopreventive agents for colon cancer...

Background: Cetuximab is crucial in the management of squamous cell carcinoma of the head and neck of patients. Grade 3-4 cetuximab-induced infusion reactions (CI-IRs) occur in 2% of patients with colorectal cancer. Despite the 2.7% CI-IR rate in the EXTREME trial, higher rates were reported in small series of patients with head and neck squamous cell carcinoma (HNSCC) (6%-18%). There is an urgent need to better appraise the natural history and the predictive factors for CI-IRs in patients with HNSCC exposed to cetuximab...

The haem biosynthetic pathway is of fundamental importance for cellular metabolism both for the erythroid and nonerythroid tissues. There are several genetic variants of the pathway in the human population that cause dysfunction of one or other of the enzymes resulting in porphyrias of varying severity. Serious chronic hepatic and systemic diseases may result. Some of these can be precipitated by exposure to drugs including hormones, barbiturates and antibiotics, as well as alcohol and particular chlorinated aromatic chemicals...

Antigen presentation lies at the heart of immune recognition of infected or malignant cells. For this reason, important efforts have been made to predict which peptides are more likely to bind and be presented by the human leukocyte antigen (HLA) complex at the surface of cells. These predictions have become even more important with the advent of next-generation sequencing technologies that enable researchers and clinicians to rapidly determine the sequences of pathogens (and their multiple variants) or identify non-synonymous genetic alterations in cancer cells...

Vitis vinifera (grape) is one of the "most-produced fruit" in the world. Grape seeds are a valuable source of phenolic compounds including resveratrol (RSV). Grape and one of its biologically active constituents, RSV, exert their protective effects against different natural or chemical toxins which could alter physiological homeostasis through a variety of mechanisms. Some of these mechanisms of actions include increase in superoxide dismutase, hemeoxygenase-1, and glutathione peroxidase activities and reduced glutathione content and decrease in malondialdehyde (MDA) levels and activation of the nuclear erythroid2-related factor2/ARE pathway...

Maslinic acid (2α,3β-dihydroxyolean-12-en-28-oic acid) is a naturally occurring pentacyclic triterpenic compound. Maslinic acid is gradually gaining attention as an excellent pharmacologically active product because of its premium biological properties. In this review we will focus on chemopreventive properties of Maslinic acid against different cancers. Seemingly, available data is limited and we have yet to unravel how Maslinic acid therapeutically targeted oncogenic cell signal transduction cascades in different cancers...

Epigenetics is the main mechanism that controls transcription of specific genes with no changes in the underlying DNA sequences. Epigenetic alterations lead to abnormal gene expression patterns that contribute to carcinogenesis and persist throughout disease progression. Because of the reversible nature, epigenetic modifications emerge as promising anticancer drug targets. Several compounds have been developed to reverse the aberrant activities of enzymes involved in epigenetic regulation, and some of them show encouraging results in both preclinical and clinical studies...

Cancer is the second biggest cause of death worldwide. Despite a number of studies being conducted, the effective mechanism for treating cancer has not yet been fully understood. The tumor-microenvironment such as hypoxia, low nutrients could disturb function of endoplasmic reticulum (ER) to maintain cellular homeostasis, ultimately leading to the accumulation of unfolded proteins in ER, so-called ER stress. The ER stress has a close relation with cancer. ER stress initiates unfolded protein response (UPR) to re-establish ER homeostasis as an adaptive pathway in cancer...
