Immune Checkpoints in Endometrial Cancer
Endometrial cancer (EC) occurs when cancer cells proliferate in the lining of the uterus, called the endometrium. This disease primarily occurs in post-menopausal women and often shows symptoms such as abnormal vaginal bleeding and discharge or severe pelvic pain. Due to poor outcome with conventional therapy, novel treatment options such as immune checkpoint inhibitors are urgently needed for advanced/ recurrent disease EC.

MicroRNA Biomarkers in Prostate Cancer by Ultrasound-Based Identification
MiRNAs are ~22-nucleotide long noncoding sequences of RNA that are located across the genome, within an intron or untranslated region (UTR) of a coding gene. Pri-miRNAs are transcribed from their genes in longer primary transcripts which are processed by two RNase III proteins—Drosha and Dicer—to form a functional miRISC complex that binds to the 3′ UTR of target mRNAs and induces their degradation and translational repression . miRNAs were found to be highly stable in blood and other body fluids, where they circulate in a cell-free form, bound to other proteins, lipids, or lipoprotein or encapsulated in exosomes. The development of specific high-throughput detection methods allowing miRNA detection in extracellular fluids, besides the fact that profiles of miRNAs were shown to be either downregulated or overexpressed across several cancer types compared to normal counterparts, has paved the way for serum miRNAs to be developed as biomarkers for early detection and monitoring of tumor evolution. However, significant challenges remain, such as the low concentration of miRNAs released in the blood, especially in early-stage disease, and the difficult identification of biomarker release sites.

Colorectal Cancer Stem Cells
Colorectal cancer stem cells (CCSCs) is a small cells population with stemness behaviors and responsible for tumor progression, recurrence, and therapy resistance. The generation of CCSCs is probably connected to genetic changes in members of signaling pathways, which control self-renewal and pluripotency in SCs and then establish function and phenotype of CCSCs. Particularly, various deregulated CCSC-related miRNAs have been reported to modulate stemness features, controlling CCSCs functions such as regulation of cell cycle genes expression, epithelial-mesenchymal transition, metastasization, and drug-resistance mechanisms. Primarily, CCSC-related miRNAs work by regulating mainly signal pathways known to be involved in CCSCs biology.

Capmatinib in Treatment of Non-Small Cell Lung Cancer
Non-small cell lung cancer (NSCLC) is a leading cause of death. Capmatinib is a Type Ib MET Tyrosine Kinase Inhibitor (TKI) first discovered in 2011 and was Food and Drug Administration (FDA) approved in August 2022 for advanced NSCLC with MET exon 14 skipping mutation. Clinical trials now involve combination therapy with capmatinib, including amivantamab, trametinib, and immunotherapy. Furthermore, new drug agents, particularly antibody–drug conjugates, are being developed to help treat patients with acquired resistance from capmatinib and other tyrosine kinase inhibitors (TKIs).

Oligometastatic Prostate Cancer
The oligometastatic prostate cancer state is defined as the presence of a number of lesions ≤ 5 and has been significantly correlated with better survival if compared to a number of metastases > 5. In particular, patients in an oligometastatic setting could benefit from a metastates directed therapy, which could control the disease delaying the start of systemic therapies. For this reason, the selection of true-oligometastatic patients who could benefit from such approach is particularly important in this setting.

ALT Positivity in Human Cancers
Neoplastic cells typically activate one of the two Telomere Maintenance Mechanisms(TMM) to maintain their telomeres during uncontrolled proliferation. Most tumors reactivatetelomerase, a high-fidelity DNA transferase with reverse transcriptase activity. The prevalence of telomerase positive cancers is at 80–90% of all malignancies. A significant percentage of neoplasias activate the second type of TMM, called alternativelengthening of telomeres (ALT), to achieve replicative immortality and telomereelongation. ALT is commonly thought to occur in about 10–20% of all tumors. Unlike the TEL+ tumors, which rely on the enzymatic activity of a single enzyme,ALT relies on many DNA damage response (DDR) proteins, including those involved inthe homology-dependent repair (HDR) pathway.

Regulation of Dickkopf-3 in Tumor Stromal Cells
Dickkopf-3 (Dkk-3) is a member of the Dickkopf family protein of secreted Wingless-related integration site (Wnt) antagonists that appears to modulate regulators of the host microenvironment. In contrast to the clear anti-tumorigenic effects of Dkk-3-based gene therapies, the role of endogenous Dkk-3 in cancer is context-dependent, with elevated expression associated with tumor promotion and suppression in different settings. The receptors and effectors that mediate the diverse effects of Dkk-3 have not been characterized in detail, contributing to an ongoing mystery of its mechanism of action.

Delta Radiomics in Head and Neck Cancers
Delta (Δ) radiomics, a concept based on the variation of parameters extracted from medical imaging using artificial intelligence (AI) algorithms, demonstrates its potential as a predictive biomarker of treatment response in head and neck cancers (HNC). The concept of image-guided radiotherapy (IGRT), including computer tomography simulation (CT) and position control imaging with cone-beam-computed tomography (CBCT), now offers new perspectives for radiomics applied in radiotherapy. The use of Δ features of texture, shape, and size, both from the primary tumor and from the tumor-involved lymph nodes, demonstrates the best predictive accuracy. If, in the case of treatment response, promising Δ radiomics results could be obtained, even after 24 h from the start of treatment, for radiation-induced xerostomia, the evaluation of Δ radiomics in the middle of treatment could be recommended.

Circulating Tumor Plasma Cells Detection
Cancer dissemination and distant metastasis most frequently require the release of tumor cells into the blood circulation, both in solid tumors and most hematological malignancies, including plasma cell neoplasms. However, detection of blood circulating tumor cells in solid tumors and some hematological malignancies, such as the majority of mature/peripheral B-cell lymphomas and monoclonal gammopathies, has long been a challenge due to their very low frequency. In recent years, the availability of highly-sensitive and standardized methods for the detection of circulating tumor plasma cells (CTPC) in monoclonal gammopathies, e.g., next-generation flow cytometry (NGF), demonstrated the systematic presence of CTPC in blood in virtually every smoldering (SMM) and symptomatic multiple myeloma (MM) patient studied at diagnosis, and in the majority of patients with newly-diagnosed monoclonal gammopathies of undetermined significance (MGUS). These methods set the basis for further detailed characterization of CTPC vs. their bone marrow counterpart in monoclonal gammopathies, to investigate their role in the biology of the disease, and to confirm their strong impact on patient outcome when measured both at diagnosis and after initiating therapy.

Thyroid Hormone Receptor Beta
There is compelling evidence that the nuclear receptor TRβ, a member of the thyroid hormone receptor (TR) family, is a tumor suppressor in thyroid, breast, and other solid tumors. Cell-based and animal studies reveal that the liganded TRβ induces apoptosis, reduces an aggressive phenotype, decreases stem cell populations, and slows tumor growth through modulation of a complex interplay of transcriptional networks. TRβ-driven tumor suppressive transcriptomic signatures include repression of known drivers of proliferation such as PI3K/Akt pathway, activation of novel signaling such as JAK1/STAT1, and metabolic reprogramming in both thyroid and breast cancers. The presence of TRβ is also correlated with a positive prognosis and response to therapeutics in BRCA+ and triple-negative breast cancers, respectively. Ligand activation of TRβ enhances sensitivity to chemotherapeutics. TRβ co-regulators and bromodomain-containing chromatin remodeling proteins are emergent therapeutic targets.

Transforming Growth Factor-Beta Signaling Activation in Cancer-Induced Cachexia
Cachexia is a metabolic syndrome consisting of massive loss of muscle mass and function that has a severe impact on the quality of life and survival of cancer patients. Up to 20% of lung cancer patients and up to 80% of pancreatic cancer patients are diagnosed with cachexia, leading to death in 20% of them. The main drivers of cachexia are cytokines such as interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), macrophage inhibitory cytokine 1 (MIC-1/GDF15) and transforming growth factor-beta (TGF-β). Besides its double-edged role as a tumor suppressor and activator, TGF-β causes muscle loss through myostatin-based signaling, involved in the reduction in protein synthesis and enhanced protein degradation.

STAT3 in Cell Cycle Arrest and Regulation
There are seven STATs (STAT1, STAT2, STAT3, STAT4, STAT5a, STAT5b, and STAT6) that are intracellular proteins which function as signal messengers and transcription factors. They transmit signals from cytokines, growth factors, intracellular kinases, mutated oncoproteins, and other signaling pathways to the nucleus. STAT3 play critical roles within neoplastic cells, immune cells, and other stromal cells, such as cancer-associated fibroblasts (CAFs).

Survival in Metastatic Prostate Cancer
The real-world survival trends are largely unexplored in patients with de novo metastatic prostate cancer. A recent population-based analysis provided data about the survival improvements in patients with de novo metastatic prostate cancer diagnosed in USA between 2000 and 2014. Despite the advent of several new drugs, limited improvements in overall and cancer-specific survival were observed in 2011-2014 compared to 2000-2003 and 2004-2010.

FOXO3, Autophagy and Sorafenib Resistance in Human Hepatocarcinoma
Early development of resistance to sorafenib accounts for the poor prognosis of advanced hepatocarcinoma (HCC). Autophagy, a double-edge autodegradative and recycling process, has been related to the modulation of drug sensitivity in cancer cells. The transcription factor forkhead box O3 (FOXO3) has been associated with the pathogenesis of HCC, but the involvement of FOXO3 on autophagy-related sorafenib resistance in HCC needs to be further investigated. A recent research verified that HCC cells are able to surpass sorafenib effects during chemoresistance acquisition via the upregulation of FOXO3 and the subsequent induction of a pro-survival autophagy. Hence, FOXO3-associated autophagy could constitute a novel therapeutic target in the advanced HCC landscape.
