Despite significantly improving outcomes in patients with B-cell malignancies, covalent Bruton tyrosine kinase (BTK) inhibitors are limited by toxicities and the development of resistance. Some toxicities can be life-threatening, such as cardiotoxicity. These toxicities result from off-target effects of covalent BTK inhibitors and frequently lead to dose reductions and discontinuations of the drug. Noncovalent BTK inhibitors bind BTK in a unique fashion and, to date, have demonstrated an excellent safety profile as well as efficacy against a variety of B-cell malignancies...

The standard treatment of patients with advanced or recurrent endometrial cancer has not significantly changed over the past few decades, reflecting a major unmet clinical need. Fortunately, the arrival of immune checkpoint inhibition is rapidly changing this dismal scenario. This review discusses the most recent results from clinical trials evaluating the use of immune checkpoint inhibitors, either as monotherapy or in combination therapy, in both the post-platinum and frontline settings. Additionally, a section is devoted to the future clinical development of immune checkpoint inhibitors in advanced or recurrent endometrial cancer...

The treatment landscape for BCR/ABL-negative myeloproliferative neoplasms (MPNs), driven by JAK2, CALR, and MPL mutations, has evolved significantly over the last decade. Recent regulatory approvals in polycythemia vera (PV) include the JAK inhibitor ruxolitinib, and more recently, a novel recombinant interferon alfa-2 (IFN-α) therapeutic agent. Many clinical trials have documented the safety and efficacy of IFN-α therapy in PV and essential thrombocythemia, the classical BCR/ABL-negative MPNs. Used off-label for more than 30 years as a cytoreductive agent, IFN-α therapy promotes significant clinical, hematologic, and molecular responses...

Kirsten rat sarcoma virus (KRAS) is the most frequently mutated oncogene in human cancers, particularly in non-small cell lung cancer (NSCLC), where mutations are present in 32% of lung adenocarcinoma and 4% of squamous cell lung cancer. The most common KRAS variant is KRAS G12C, which accounts for nearly 40% of all KRAS mutations. Although it is the most common oncogenic driver in NSCLC, KRAS was considered a "nondruggable target" until recently, owing to the lack of any progress in developing targeted therapies for this oncogene...

Liquid biopsy is a test that allows for the diagnosis and analysis of cancer by sampling cancer cells or byproducts present in biological fluids such as blood or urine. It has the potential to create a new paradigm in oncologic care, being a less invasive approach than conventional tissue biopsy. Liquid biopsy has multifaceted applications for longitudinal disease monitoring in terms of surveillance, treatment response, and identification of emerging resistance mechanisms. Multiple assays currently exist or are in development for detecting circulating tumor cells, DNA, RNA, exosomes, proteins, fragmentomic markers, and metabolomes...

Polycythemia vera is a Philadelphia chromosome-negative myeloproliferative neoplasm characterized by the clonal proliferation of hematopoietic cells, leading to the overproduction of erythrocytes and the elaboration of inflammatory cytokines. Management is aimed at reducing the risk of thromboembolic events, alleviating the symptom burden, decreasing splenomegaly, and potentially mitigating the risk of disease progression. Existing treatment options include therapeutic phlebotomy and cytoreductive agents including hydroxyurea, pegylated recombinant interferon alpha 2a, ropegylated recombinant interferon alpha 2b, and ruxolitinib...
