Neoantigen-Derived Cancer Vaccines
Cancers are driven by genetic instabilities that rapidly accumulate somatic mutations and eventually alter cell properties. Cancer immunotherapy has achieved multiple clinical benefits and has become an indispensable component of cancer treatment. Targeting tumor-specific antigens, also known as neoantigens, plays a crucial role in cancer immunotherapy. T cells of adaptive immunity that recognize neoantigens, but do not induce unwanted off-target effects, have demonstrated high efficacy and low side effects in cancer immunotherapy.

Atypical Endometriosis-Associated Biomarkers
Ovarian endometriosis may increase the risk of malignancy. Several studies have suggested atypical endometriosis as the direct precursor of endometriosis-associated ovarian cancer. Atypical endometriosis can be a transitioning entity from endometriosis to endometriosis-associated ovarian cancers. 39 studies assessing numerous molecular targets of AE, such as immunohistochemical expression of BAF250, PIK3CA, PTEN, HNF-1beta, ER, and PR. Unfortunately, these molecular biomarkers of AE require expensive molecular analysis, histological examination is always needed, and none of them has such strong evidence to justify their systematic use in the management of the neoplastic risk of endometriosis. Further studies are needed to validate evidence on available biomarkers for the presence of AE, which is a high oncologic risk condition. Moreover, the introduction of novel serum biomarkers could be useful for the non-invasive diagnosis of AE.

Microneedles in Cancer Therapy and Diagnosis
The tumor is an uncontrolled growth of tissue that can be localized (benign) or possesses the capability of metastasis (malignant). The conventional methods of tumor diagnosis, such as acupuncture, endoscopy, and histopathology, and treatment methods, such as injections, chemotherapy, surgery, and radiotherapy, are invasive, expensive, and pose severe safety and management issues for the patients. Microneedle technology is minimally invasive, self-administrable, bypasses the first-pass effect, effectively delivers chemotherapeutics and drugs at low doses, and provides drug diffusion into the tumor areas, thus, overcoming the drawbacks of conventional delivery systems.

Colorectal Cancer Prevention via Modulation of Gut Microbiota
Colorectal cancer (CRC) is the second most frequent cause of cancer-related mortality among all types of malignancies. Sedentary lifestyles, obesity, smoking, red and processed meat, low-fiber diets, inflammatory bowel disease, and gut dysbiosis are the most important risk factors associated with CRC pathogenesis. Alterations in gut microbiota are positively correlated with colorectal carcinogenesis, as these can dysregulate the immune response, alter the gut’s metabolic profile, modify the molecular processes in colonocytes, and initiate mutagenesis. Changes in the daily diet, and the addition of plant-based nutraceuticals, have the ability to modulate the composition and functionality of the gut microbiota, maintaining gut homeostasis and regulating host immune and inflammatory responses.

Ubiquilin Networking in Cancers
Ubiquilins or UBQLNs, members of the ubiquitin-like and ubiquitin-associated domain (UBL-UBA) protein family, serve as adaptors to coordinate the degradation of specific substrates via both proteasome and autophagy pathways. The UBQLN substrates reveal great diversity and impact a wide range of cellular functions. For decades, researchers have been attempting to uncover a puzzle and understand the role of UBQLNs in human cancers, particularly in the modulation of oncogene’s stability and nucleotide excision repair.

Chloride Intracellular Channel Proteins and Malignant Tumor Progression
Chloride intracellular channel proteins (CLICs are the dimorphic protein present in both soluble and membrane fractions. As an integral membrane protein, CLICs potentially possess ion channel activity. In vertebrates, CLICs are classified into six classes: CLIC1, 2, 3, 4, 5, and 6. CLIC2 is expressed at higher levels in benign tumors than in malignant ones, most likely preventing tumor cell invasion into surrounding tissues. CLIC2 is also expressed in the vascular endothelial cells of normal tissues and maintains their intercellular adhesive junctions, presumably suppressing the hematogenous metastasis of malignant tumor cells.

Flavonoids and Curcuminoids for CTCs
Cancer, especially in metastatic stages is a dangerous  disease with high mortality. Majority of deaths of oncology patients are not caused by the primary tumour, but by metastasis. Circulating tumour cells (CTCs, one most potent metastatic factor)  are seen not only as an isolated phenomenon but also a key inherent part of the formation of metastasis and a key factor in cancer death. Low-toxicity natural anticancer such as curcuminoids and flavonoids), are promising agents for targeting CTC spreading. Their potential is discussed in the context of key mechanisms of tumour biology with a strong influence on CTC spread and metastasis (mechanisms related to tumour-associated and -infiltrating cells, epithelial–mesenchymal transition, and migration of cancer cells).

The Selected Rare B-Cell Lymphoproliferative Disorders
The updated 4th edition WHO classification of lymphoid malignancies and certain lymphoproliferative disorders (LPD), released in 2016, contains pivotal new terminology and information that is important for both radiologists and oncologists to understand. In spite of these updates, some LPDs included within this update have been rarely discussed in radiology literature. Many of these disorders have distinct clinical and imaging features, overlapping with more common disorders. The purpose of this entry is provide an overview for radiologists regarding certain rare LPDs.

Cardiotoxicity of Fluoropyrimidines
The definition of cardiotoxicity includes not only clinical symptoms but also changes in left ventricular ejection fraction or histopathological changes in cardiomyocytes. Cardiotoxicity is a rare but serious complication of cytostatic agents, defined as a negative impact on heart function or cardiac cells. Fluoropyrimidine cardiotoxicity was first described in 1969, and since then, many studies have confirmed these findings, but many details such as incidence, mechanisms, and treatment are unclear and remain disputed.

Chloroquine and Hydroxychloroquine
The chloroquine family of antimalarials has a long history of use, spanning many decades. Despite this extensive clinical experience, novel applications, including use in autoimmune disor-ders, infectious disease, and cancer, have only recently been identified. While short term use of chloroquine or hydroxychloroquine is safe at traditional therapeutic doses in patients without pre-disposing conditions, administration of higher doses and for longer durations are associated with toxicity, including retinotoxicity. Additional liabilities of these medications include pharmacokinetic profiles that require extended dosing to achieve therapeutic tissue concentrations. To improve chloroquine therapy, researchers have turned toward nanomedicine reformulation of chloroquine and hydroxychloroquine to increase exposure of target tissues relative to off-target tissues, thereby improving the therapeutic index.

Circadian Clock and Liver Cancer
Circadian clocks control several homeostatic processes in mammals through internal molecular mechanisms. Chronic perturbation of circadian rhythms is associated with metabolic diseases and increased cancer risk, including liver cancer. The hepatic physiology follows a daily rhythm, driven by clock genes that control the expression of several proteins involved in distinct metabolic pathways. Alteration of the liver clock results in metabolic disorders, such as non-alcoholic fatty liver diseases (NAFLD) and impaired glucose metabolism, that can trigger the activation of oncogenic pathways, inducing spontaneous hepatocarcinoma (HCC). The study of oncogenic changes related to alterations of liver clock provides new potentially useful targets for prevention and management of HCC.

Nonsteroidal Anti-Inflammatory Drugs in Prostate Cancer
Prostate cancer (PC) is the second most common type of cancer and the leading cause of death among men worldwide. Preventing the progression of cancer after treatments such as radical prostatectomy, radiation therapy, and hormone therapy is a major concern faced by prostate cancer patients. Inflammation, which can be caused by various factors such as infections, the microbiome, obesity and a high-fat diet, is considered to be the main cause of PC. Inflammatory cells are believed to play a crucial role in tumor progression. Therefore, nonsteroidal anti-inflammatory drugs (NSAIDs) along with their effects on the treatment of inflammation-related diseases, can prevent cancer and its progression by suppressing various inflammatory pathways. Evidence shows that nonsteroidal anti-inflammatory drugs are effective in the prevention and treatment of prostate cancer.

Triple-Negative Breast Cancer
Triple negative breast cancer (TNBC) is a heterogeneous tumor characterized by early recurrence, high invasion, and poor prognosis. Currently, its treatment includes chemotherapy, which shows a suboptimal efficacy. However, with the increasing studies on TNBC subtypes and tumor molecular biology, great progress has been made in targeted therapy for TNBC. The new developments in the treatment of breast cancer include targeted therapy, which has the advantages of accurate positioning, high efficiency, and low toxicity, as compared to surgery, radiotherapy, and chemotherapy. Given its importance as cancer treatment, we review the latest research on the subtypes of TNBC and relevant targeted therapies.
