COVID-19 infection in cancer patients: what has been the contribution of Associazione Italiana Oncologia Medica (AIOM) to oncological care since the …
2021
High mortality rates in elderly patients or in those with underlying chronic illnesses and/or a compromised immune system is a peculiar feature of COVID-19 infection. The possible coexistence of a cancer and COVID-19 infection in the same individual prompted concerns regarding their synergistic effect on prognosis. In order to balance patients’ needs with the risks related to the infection, the question oncologists have asked from the beginning of the first wave of the pandemic has been: ‘how can we deal with COVID-19 infection in cancer patients?’ In pursuing its mission, the Associazione Italiana Oncologia Medica (AIOM) has made every possible effort to support cancer patients, health car…
Myeloid-Derived Suppressor Cells in Multiple Myeloma: Pre-Clinical Research and Translational Opportunities
2014
Immunosuppressive cells have been reported to play an important role in tumor-progression mainly because of their capability to promote immune-escape, angiogenesis, and metastasis. Among them, myeloid-derived suppressor cells (MDSCs) have been recently identified as immature myeloid cells, induced by tumor-associated inflammation, able to impair both innate and adaptive immunity. While murine MDSCs are usually identified by the expression of CD11b and Gr1, human MDSCs represent a more heterogeneous population characterized by the expression of CD33 and CD11b, low or no HLA-DR, and variable CD14 and CD15. In particular, the last two may alternatively identify monocyte-like or granulocyte-lik…
Targeting MYCN in Pediatric and Adult Cancers
2021
The deregulation of theMYCfamily of oncogenes, includingc-MYC,MYCNandMYCLoccurs in many types of cancers, and is frequently associated with a poor prognosis. The majority of functional studies have focused onc-MYCdue to its broad expression profile in human cancers. The existence of highly conserved functional domains betweenMYCNandc-MYCsuggests thatMYCNparticipates in similar activities.MYCencodes a basic helix-loop-helix-leucine zipper (bHLH-LZ) transcription factor (TF) whose central oncogenic role in many human cancers makes it a highly desirable therapeutic target. Historically, as a TF, MYC has been regarded as “undruggable”. Thus, recent efforts focus on investigating methods to indi…

Cyclin dependent kinase-1 (Cdk-1) inhibition as a novel therapeutic strategy against pancreatic ductal adenocarcinoma (pdac)
2021
Simple Summary Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers in humans, due to late diagnosis and limited treatment possibilities. Improved treatment for PDAC patients is warranted. Cyclin-dependent kinase 1 (CDK1) is a stimulator of cell cycle progression and its activity is regularly enhanced in pancreatic cancer cells. Therefore, CDK1 has been proposed as a novel drug target to treat patients with PDAC. This review describes the potential of CDK1 inhibition as a treatment for PDAC by outlining the molecular pathways influenced by CDK1 inhibition and new therapeutic strategies. Abstract The role of CDK1 in PDAC onset and development is two-fold. Firstly, since …
Management of patients with chronic lymphocytic leukemia during the SARS‑CoV‑2 pandemic (Review)
2021
Oncohematological patients are prone to develop infections due to immunosuppression caused by the disease and chemo-immunotherapy. The aim of this review was to outline the details of the management of patients with chronic lymphocytic leukemia (CLL) during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Patients with CLL often exhibit inadequate humoral and cellular immune responses to various infections and vaccinations. Patients under the ‘watch and wait’ strategy have a lower risk of infections, including with SARS-CoV-2, compared with those undergoing therapeutic interventions, but they still have a higher risk than age-matched controls. Patients with CLL hav…
Brain Mapping-Aided SupraTotal Resection (SpTR) of Brain Tumors: The Role of Brain Connectivity
2021
Brain gliomas require a deep knowledge of their effects on brain connectivity. Understanding the complex relationship between tumor and functional brain is the preliminary and fundamental step for the subsequent surgery. The extent of resection (EOR) is an independent variable of surgical effectiveness and it correlates with the overall survival. Until now, great efforts have been made to achieve gross total resection (GTR) as the standard of care of brain tumor patients. However, high and low-grade gliomas have an infiltrative behavior and peritumoral white matter is often infiltrated by tumoral cells. According to these evidences, many efforts have been made to push the boundary of the re…
Aurora kinases in ovarian cancer
2020
Aurora kinases (AURK) are key regulators of the mitotic spindle formation. AURK is frequently overexpressed in ovarian cancer and this overexpression has been frequently associated with prognosis in these tumours. Interestingly, AURK have been shown to interact with DNA repair mechanisms and other cell cycle regulators. These functions have brought light to Aurora family as a potential target for anticancer therapy. In the last years, two clinical trials with different AURK inhibitors have shown activity in epithelial and clear-cell ovarian cancer. Although there is a lack of predictive factors of AURK inhibition activity, recent trials have identified some candidates. This review will focu…
Stabilizing versus Destabilizing the Microtubules: A Double-Edge Sword for an Effective Cancer Treatment Option?
2015
Microtubules are dynamic and structural cellular components involved in several cell functions, including cell shape, motility, and intracellular trafficking. In proliferating cells, they are essential components in the division process through the formation of the mitotic spindle. As a result of these functions, tubulin and microtubules are targets for anticancer agents. Microtubule-targeting agents can be divided into two groups: microtubule-stabilizing, and microtubule-destabilizing agents. The former bind to the tubulin polymer and stabilize microtubules, while the latter bind to the tubulin dimers and destabilize microtubules. Alteration of tubulin-microtubule equilibrium determines th…
Recurrences following treatment of proliferative verrucous leukoplakia: A systematic review and meta-analysis.
2021
Objective A systematic review and meta-analysis was made of the incidence of recurrences in patients with proliferative verrucous leukoplakia subjected to different types of treatment. Methods The study was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. A literature search was made in the Medline (PubMed), EMBASE and Web of Science databases, together with a manual search, covering the period from 1985 to January 2020, with no language restrictions. Studies were included if they described treatments applied to at least 10 patients with the corresponding outcomes. Methodological quality was evaluated using Jadad sca…
