The Changing Landscape of Systemic Treatment of Advanced Hepatocellular Carcinoma: New Targeted Agents and Immunotherapies.

Hepatocellular carcinoma (HCC) is one of the most common and deadliest cancers worldwide with a rising incidence in the Western world. HCCs are characterized by high resistance to systemic therapies induced by phenotypic and molecular heterogeneity. For almost 10 years, the tyrosine kinase inhibitor sorafenib was the only approved treatment for advanced HCCs in patients with preserved liver function, and until 2016, no new compounds tested in large phase III studies have led to a survival benefit. The tyro...

The Challenge of Managing Bladder Cancer and Upper Tract Urothelial Carcinoma: A Review with Treatment Recommendations from the Spanish Oncology Genitourinary Group (SOGUG).

Bladder cancer is the fourth most common cancer in men and the ninth most common in women in the Western world. The management of bladder carcinoma requires a multidisciplinary approach. Optimal treatment depends on several factors, including histology, stage, patient status, and possible comorbidities. Here we review recent findings on the treatment of muscle-invasive bladder carcinoma, advanced urothelial carcinoma, upper tract urothelial carcinoma, non-urothelial carcinoma, and urologic complications ari...

Outcomes for Metastatic Colorectal Cancer Based on Microsatellite Instability: Results from the South Australian Metastatic Colorectal Cancer Registry.

Microsatellite instability (MSI) is the molecular marker for DNA mismatch repair deficiency (dMMR) in colorectal cancer (CRC) and has been associated with better survival outcomes in early stage disease. In metastatic CRC (mCRC), outcomes for patients with MSI are less clear. There is evolving evidence that treatment pathways for MSI CRC should include programmed-death 1 (PD-1) antibodies.

Development of a Novel EGFR-Targeting Antibody-Drug Conjugate for Pancreatic Cancer Therapy.

Overexpression of epidermal growth factor receptor (EGFR) is common in pancreatic cancer and associated with the poor prognosis of this malignancy.

New Horizons in the Treatment of Metastatic Pancreatic Cancer: A Review of the Key Biology Features and the Most Recent Advances to Treat Metastatic Pancreatic Cancer.

Only a limited number of therapeutic strategies are available for patients diagnosed with pancreatic adenocarcinoma, and disease recurrence and mortality are consequently high. For metastatic disease, two combinations are approved in the first line setting: a triplet with 5-fluoruracil, irinotecan, and oxaliplatin, and the combination of gemcitabine and nab-paclitaxel. In patients who have progressed on gemcitabine, a new nanoliposomal formulation of irinotecan has recently been approved. While these treatm...

Targeting the Proteasome in Refractory Pediatric Leukemia Cells: Characterization of Effective Cytotoxicity of Carfilzomib.

Leukemia accounts for 30% of all childhood cancers and although the survival rate for pediatric leukemia has greatly improved, relapse is a major cause of treatment failure. Therefore, the development and introduction of novel therapeutics to treat relapsed pediatric leukemia is urgently needed. The proteasome inhibitor bortezomib has been shown to be effective against adult hematological malignancies such as multiple myeloma and lymphoma, but is frequently associated with the development of resistance. Car...

Real-World Use and Outcomes of Olaparib: a Population-Based Cohort Study.

Although olaparib, the first poly (adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitor approved, has been used in routine clinical practice for over three years, little has been published on its uptake, utilization patterns, and clinical outcomes.

Immunological Correlates of Response to Immune Checkpoint Inhibitors in Metastatic Urothelial Carcinoma.

The identification of prognostic and/or predictive biomarkers for response to immune checkpoint inhibitors (ICI) could help guide treatment decisions.

Characteristics and Response to Crizotinib in ALK-Rearranged, Advanced Non-Adenocarcinoma, Non-Small Cell Lung Cancer (NA-NSCLC) Patients: a Retrospective Study and Literature Review.

Oncogenic fusion genes consisting of echinoderm microtubule-associated protein-like 4 (EML4) and anaplastic lymphoma kinase (ALK) can be detected in 5-7% of lung adenocarcinoma cases. The prevalence of ALK rearrangement in non-adenocarcinoma, non-small cell lung cancers (NA-NSCLC) is currently unknown. In addition, the efficacy of crizotinib in these patients has not been well established.

Targeted Therapies in the Treatment of Sarcomas.

About 50% of sarcomas have specific pathology-defining molecular alterations including mutations, fusion genes, and gene amplifications. Some of these alterations appear to be oncogenic drivers, and a subset can be utilized as targets for standard or experimental molecularly targeted agents in the clinic. In addition, immunotherapies may have a growing role in the treatment of sarcomas in the future.

Coronary Toxicities of Anti-PD-1 and Anti-PD-L1 Immunotherapies: a Case Report and Review of the Literature and International Registries.

Immunotherapy medications that target programmed death 1 protein (PD-1) and programmed death-ligand 1 (PD-L1), such as nivolumab, pembrolizumab, and atezolizumab, are currently used in the first- or second-line treatment of non-small cell lung cancers, among other indications. However, these agents are associated with immune-related side effects, the most common of which are endocrinopathies, colitis, hepatitis, and interstitial pneumonitis. In contrast, coronary toxicities are rarely reported and remain po...

MicroRNAs as Mediators of Resistance Mechanisms to Small-Molecule Tyrosine Kinase Inhibitors in Solid Tumours.

Receptor tyrosine kinases (RTKs) are widely expressed transmembrane proteins that act as receptors for growth factors and other extracellular signalling molecules. Upon ligand binding, RTKs activate intracellular signalling cascades, and as such are involved in a broad variety of cellular functions including differentiation, proliferation, migration, invasion, angiogenesis, and survival under physiological as well as pathological conditions. Aberrant RTK activation can lead to benign proliferative condition...

Inflammatory Indexes as Prognostic and Predictive Factors in Ovarian Cancer Treated with Chemotherapy Alone or Together with Bevacizumab. A Multicenter, Retrospective Analysis by the MITO Group (MITO 24).

The variability in progression-free survival (PFS) and overall survival (OS) among patients with epithelial ovarian cancer (EOC) makes it difficult to reliably predict outcomes. A predictive biomarker of bevacizumab efficacy as first-line therapy in EOC is still lacking.

BIM Deletion Polymorphism Confers Resistance to Osimertinib in EGFR T790M Lung Cancer: a Case Report and Literature Review.

The third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) osimertinib (AZD9291) has shown significant clinical efficacy against the EGFR T790M mutation in non-small cell lung cancer (NSCLC) patients. However, resistance inevitably occurs, and the mechanisms leading to treatment failure need to be further investigated. The B-cell lymphoma 2 (BCL-2)-like 11 (BIM) deletion polymorphism, which occurs at a frequency of 21% in East Asians but is absent in African and European po...

Discovery of a Potent and Mutant-Selective EGFR Inhibitor that Overcomes T790M-Mediated Resistance in Lung Cancer.

Despite remarkable activity in epidermal growth factor receptor (EGFR)-mutant lung cancer patients, the clinical efficacy of EGFR tyrosine kinase inhibitors (TKIs) is limited by the emergence of acquired resistance, which is mostly caused by a secondary T790M mutation. Fortunately, newly developed, mutant-selective EGFR-TKIs against T790M have been proven as an effective therapeutic approach although only osimertinib has received the FDA approval until now.

The Role of Mesothelin as a Diagnostic and Therapeutic Target in Pancreatic Ductal Adenocarcinoma: A Comprehensive Review.

Mesothelin is a tumor differentiation antigen, which is highly expressed in several solid neoplasms, including pancreatic cancer. Its selective expression on malignant cells and on only a limited number of healthy tissues has made it an interesting candidate for investigation as a diagnostic and prognostic biomarker and as a therapeutic target. Based on a strong preclinical rationale, a number of therapeutic agents targeting mesothelin have entered clinical trials, including immunotoxins, monoclonal antibod...

The Abscopal Effect in the Era of Cancer Immunotherapy: a Spontaneous Synergism Boosting Anti-tumor Immunity?

Radiotherapy is one of the main treatment strategies used in cancer. Aside from the local control of the disease, which is mediated by a direct cytotoxic effect on tumor cells, radiotherapy has also been shown to exert immune-mediated local and systemic effects. Radiotherapy can elicit anti-tumor responses in distant sites from the radiation field; this phenomenon is known as the abscopal effect and has been described in patients previously treated with immune checkpoint blockade (ICB). Considering that the...

Extracellular Vesicles As miRNA Nano-Shuttles: Dual Role in Tumor Progression.

Tumor-derived extracellular vesicles (EVs) have a pleiotropic role in cancer, interacting with target cells of the tumor microenvironment, such as fibroblasts, immune and endothelial cells. EVs can modulate tumor progression, angiogenic switch, metastasis, and immune escape. These vesicles are nano-shuttles containing a wide spectrum of miRNAs that contribute to tumor progression. MiRNAs contained in extracellular vesicles (EV-miRNAs) are disseminated in the extracellular space and are able to influence the...

Biomarker-Driven Therapy in Metastatic Gastric and Esophageal Cancer: Real-Life Clinical Experience.

Precision treatment of cancer uses biomarker-driven therapy to individualize and optimize patient care.

Cetuximab/TPF/radiotherapy in oesophageal cancer.

Pre-operative chemoradiotherapy using a 5-fluorouracil (5-FU)/cisplatin backbone is widely used to improve surgical outcomes in locoregional oesophageal cancer patients, despite a non-negligible failure rate.

Antibody-Drug Conjugates for the Treatment of Solid Tumors: Clinical Experience and Latest Developments.

Antibody-drug conjugates (ADCs) are complex immunoconjugates designed to selectively deliver toxic small molecules preferentially to cancer cells. These immunoconjugates consist of a monoclonal antibody - directed to a tumor antigen - and a cytotoxic agent that is conjugated to the antibody via a molecular linker. Following the binding to a specific antigen on the surface of cancer cells, the conjugate is internalized and releases its cytotoxic payload to kill the malignant cell. ADCs that have gained regul...

Bevacizumab in Colorectal Cancer: Current Role in Treatment and the Potential of Biosimilars.

Colorectal cancer (CRC) is a leading cause of tumor-related morbidity and mortality worldwide, with mortality most often attributable to metastatic disease. Bevacizumab, a humanized monoclonal antibody targeting vascular endothelial growth factor, has a significant role in the treatment of metastatic CRC (mCRC). However, patient access to bevacizumab may be limited in some regions or circumstances, owing to factors related to insurance coverage, reimbursement, patient out-of-pocket costs, or availability. A...

A Combination of Testosterone and White Blood Cell Count as a Predictive Factor of Overall Survival in Localized Prostate Cancer.

It has been shown that neutrophil count or an elevated neutrophil-to-lymphocyte ratio (NLR) as well as testosterone levels are separately associated with increased mortality in patients with localized prostate cancer.

The pan-Bcl2 Inhibitor AT101 Activates the Intrinsic Apoptotic Pathway and Causes DNA Damage in Acute Myeloid Leukemia Stem-Like Cells.

Leukemia stem cells (LSCs) are considered to be the cause of treatment failure and relapse in acute myeloid leukemia (AML). Overexpression of the Bcl-2 family of anti-apoptotic proteins such as Bcl-2, Bcl-xl, and Mcl-1 accounts for survival and self-renewal of LSCs. AT101 binds to the BH3 motif of all Bcl-2 family anti-apoptotic proteins and demonstrates anti-tumor activity in multiple types of tumor. Thus, we hypothesized that this agent might have the potential to deplete LSCs.

Osimertinib: A Review in T790M-Positive Advanced Non-Small Cell Lung Cancer.

Osimertinib (Tagrisso™) is an oral, CNS-active, third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that targets EGFR TKI-sensitizing mutations and, crucially, the T790M mutation that often underlies acquired resistance to EGFR TKI therapy. Osimertinib has been approved in numerous countries for use in patients with T790M-positive advanced NSCLC. In the pivotal, international AURA3 trial in patients with T790M-positive advanced NSCLC who had disease progression after E...
