Abstract Hepatocellular carcinoma (HCC) is a highly aggressive malignancy, largely driven by an immunosuppressive tumor microenvironment (TME) that facilitates tumor growth, immune escape, and resistance to therapy. Although immunotherapy—particularly immune checkpoint inhibitors (ICIs)—has transformed the therapeutic landscape by restoring T cell-mediated anti-tumor responses, their clinical benefit as monotherapy remains suboptimal. This limitation is primarily attributed to immunosuppressive components within the TME, including tumor-associated macrophages, regulatory T cells (Tregs), and myeloid-derived suppressor cells (MDSCs). To address these challenges, combination strategies have been explored, such as dual checkpoint blockade targeting programmed cell death protein 1 (PD-1), programmed death-ligand More >

Abstract Checkpoint inhibitors, particularly programmed cell death-1/programmed death-ligand 1 (PD-1/PD-L1) inhibitors, have significantly advanced the treatment of Hodgkin lymphoma (HL), especially in relapsed or refractory cases. However, challenges such as resistance, immune-related adverse events (irAEs), and the need for effective patient selection remain. This review aims to explore the mechanisms of resistance to checkpoint inhibitors, including alterations in the tumor microenvironment, loss of antigen presentation, and T-cell exhaustion. Overcoming resistance may involve combination therapies, such as pairing PD-1 inhibitors with other immune checkpoint inhibitors or targeted therapies like Brentuximab vedotin. Additionally, next-generation inhibitors targeting molecules like More >

Abstract Objectives: Our previous research demonstrated that SIC-19, an innovative inhibitor of salt-inducible kinase 2 (SIK2), effectively reduces SIK2 protein levels through the ubiquitin-proteasome pathway and exhibits synthetic lethal effects with poly ADP-ribose polymerase (PARP) inhibitors in ovarian cancer. However, the role of SIC-19 in triple-negative breast cancer (TNBC) and pancreatic cancer (PC) remains poorly defined. This study aims to investigate whether SIC-19 combined with PARP inhibitors can induce synthetic lethal effects in TNBC and PC. Methods: Cell lines with high SIK2 expression were identified through Western blot analysis. The combination’s impact was evaluated using Cell… More >

Abstract Aims: The study aimed to evaluate the effectiveness and adverse events of tyrosine kinase inhibitors (TKIs) in the first-line treatment of advanced non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations. Methods: A retrospective study on advanced NSCLC patients with EGFR mutations treated with TKIs as a first-line therapy at Nghe An Oncology Hospital, Vietnam between January 2017 and August 2023. The primary endpoints included objective response rate, progression-free survival, and tolerability. The secondary endpoint was overall survival. Results: A total of 211 patients received first-line treatment with Erlotinib (n = 74), Gefitinib (n… More >

Abstract Introduction: In recent years, significant advancements in the treatment of metastatic renal cell carcinoma (mRCC) have notably extended overall survival (OS) times, particularly with the introduction of tyrosine kinase inhibitors (TKIs) and combination immunotherapy. However, survival outcomes in mRCC remain highly variable. Materials and Methods: This study retrospectively analyzed clinical and demographic factors at diagnosis in patients treated for mRCC to identify predictors of long-term survival (defined as OS ≥ 48 months). Patients were categorized into long-term survivors (LTS) and non-long-term survivors (nLTS). Results: The analysis revealed that factors such as better Karnofsky Performance Status (KPS), More >

Abstract Melanomas are aggressive cancers, with a high rate of metastatic disease. Cutaneous (CM) and uveal (UM) melanomas are intrinsically different diseases, and most cell death inducers effective for CM do not function for UM. This is primarily due to the fact the eye is an immunologically privileged organ, and it fails to achieve the efficacy of immune checkpoint inhibitors (ICIs) comparable to that for CM. However, approaches utilizing specific melanoma-associated antigens are being developed for metastatic forms of CM and UM. The most promising to date are gp100 and tyrosinase related protein 1 (TYRP1), primarily… More >

Abstract Background: immune checkpoint inhibitors (ICIs) have revolutionized the treatment of metastatic urothelial carcinoma (mUC), significantly improving survival outcomes. However, a subset of patients do not respond to ICIs, prompting research into potential predictive factors. Commonly prescribed medications such as corticosteroids, proton-pump inhibitors (PPIs), antibiotics (Abs), antihypertensives, and analgesics may influence ICI effectiveness. Methods: we conducted a literature search on PubMed to investigate the impact of concomitant medications on the outcomes of patients with mUC, treated with ICIs. We selected the most relevant studies and performed a narrative review. Results: corticosteroids, PPIs and Abs have been associated More >

Abstract Background: The JAK2^V617F mutation plays a crucial part in the pathogenesis of myeloproliferative neoplasms (MPN), which includes polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) leading to aberrant proliferation and survival of hematopoietic cells. Alongside the challenges of drug resistance and side effects, identifying novel compounds that selectively target JAK2^V617F could provide more effective and safer therapeutic options for patients with MPNs. Materials and Methods: We employed computational approaches like high-throughput virtual screening, molecular dynamics simulations (MDS), and binding free energy calculations to identify inhibitors targeting wild and mutant JAK2 kinases. JAK2^V617F positive HEL, wild… More >

Abstract Background: Previous experiments have demonstrated that hypofractionated radiation therapy (HFRT), low-dose radiation therapy (LDRT), and combined anti-programmed cell death protein 1 (αPD-1) can enhance the abscopal effect. Combined with the phenomenon of low prognosis in patients with breast cancer lung metastasis, our study establishes a mouse model and changes the irradiation regimen of LDRT to explore its preventive effect on breast cancer lung metastasis. Methods: The breast cancer subcutaneous graft tumor model was developed. Two-lung prophylactic LDRT was performed prior to the onset of lung metastases, in combination with HFRT (8 Gy, 3f), and αPD-1… More >
