Malignant pleural mesothelioma (MPM) is a rare and challenging cancer associated with asbestos fiber exposure, which offers limited treatment options. Historically, platinum-based chemotherapy has been the primary approach, but recent developments have introduced immunotherapy as a promising alternative for the treatment of this disease. Nevertheless, the unique growth patterns and occasionally ambiguous progressive characteristics of MPM make the interpretation of radiological assessments complex. Immunotherapy further complicates matters by introducing unconventional treatment response patterns such as hyperprogression and pseudoprogression...

BACKGROUND: Little is known regarding the prognostication of the Pan-Immune-Inflammation Value (PIV) in patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). OBJECTIVES: This study aimed to investigate the prognostic role of PIV in patients with R/M HNSCC receiving immune checkpoint inhibitors (ICI). PATIENTS AND METHODS: Patients who were diagnosed to have R/M HNSCC and treated with ICI were reviewed retrospectively...

BACKGROUND: PARP inhibitors (PARPis) are effective treatment options for patients with metastatic castration-resistant prostate cancer (mCRPC) as single agents or in combination with androgen receptor-targeted agents (ARTA). However, a clinically relevant adverse effect of these agents is hematological toxicity, a typical class adverse event (AE), which can lead to treatment modifications and discontinuations. OBJECTIVE: We aimed to analyze the risk of hematological AEs, including anemia, neutropenia, and thrombocytopenia secondary to PARPi treatments in mCRPC...

BACKGROUND: Although ALK-translocated (ALK+) advanced non-small cell lung cancers (aNSCLCs) are currently treated with second- or third-generation ALK inhibitors (ALK-TKIs), some patients respond durably to the first-generation ALK-TKI crizotinib. OBJECTIVE: This study aimed to describe the clinical characteristics of these long-term responders. PATIENTS AND METHODS: This national, multicenter, retrospective, non-interventional study included patients with ALK+ aNSCLCs and long-term responses to first (L1)- or subsequent (≥ L2)-line crizotinib, defined, respectively, as treatments lasting > 18 and > 10 months...

Durvalumab (Imfinzi® ), a therapeutic human monoclonal antibody which binds to and blocks the activity of the immunosuppressive programmed death-ligand 1 (PD-L1) protein, is approved in the USA, EU, Japan and other countries in combination with gemcitabine and cisplatin for adults with advanced biliary tract cancer. In the pivotal phase 3 TOPAZ-1 trial, durvalumab plus gemcitabine and cisplatin significantly prolonged overall survival and progression-free survival compared with placebo plus gemcitabine and cisplatin in adults with advanced biliary tract cancer...

BACKGROUND: Delta-like ligand 3 (DLL3), a member of the Notch pathway, has been identified as a potential therapeutic target as it is highly expressed in small cell lung cancer (SCLC), a subtype accounting for 15% of lung cancer cases. OBJECTIVE: A systematic literature review (SLR) was conducted to understand the prevalence and prognostic impact of DLL3 expression on survival of patients with SCLC and treatment response. PATIENTS AND METHODS: Systematic literature searches were conducted across multiple databases to capture studies of any SCLC population that evaluated DLL3 expression...

BACKGROUND: Chemo-immunotherapy (CIT) is the standard of care for advanced non-small cell lung cancer (NSCLC), but the impact of routinely available histo-molecular biomarkers on its efficacy has not yet been fully assessed. OBJECTIVE: The purpose of this multicenter study was to evaluate the clinical activity of CIT according to oncogenic drivers, STK11 and TP53 mutations, and MET overexpression. PATIENTS AND METHODS: Patients receiving CIT for advanced NSCLC with available comprehensive molecular profile were included...

BACKGROUND: Immune checkpoint inhibitor (ICI) monotherapy and ICI plus chemotherapy are approved first-line treatments for patients with non-small cell lung cancer (NSCLC) expressing high levels of programmed cell death-ligand 1 (PD-L1). However, appropriate treatment for patients showing high PD-L1 expression and poor performance status (PS) is not well defined. OBJECTIVE: The aim of this study was to identify a treatment option that is better for these patients in a real-world setting...

BACKGROUND: Alpelisib in combination with cetuximab showed synergistic anti-tumour activity in head and neck squamous cell carcinoma (HNSCC) models. OBJECTIVES: The recommended phase 2 dose (RP2D) was determined in a phase 1b dose-escalation study. Phase 2 evaluated anti-tumour activity with a randomised part in cetuximab-naïve patients and a non-randomised part in cetuximab-resistant patients. PATIENTS AND METHODS:  Alpelisib was administered in 28 d cycles as whole tablets, suspension from crushed tablets or suspension from dispersible tablets in patients with platinum-resistant, recurrent/metastatic HNSCC...

BACKGROUND: The efficacy of systemic treatment for primary central nervous system lymphoma (PCNSL) is limited because of the blood-brain barrier (BBB) and the ineffectiveness of chemotherapy. The dual PI3K/HDAC inhibitor BEBT-908 has exhibited favorable in vivo distribution and activity in various cancers. OBJECTIVES: The aims of this study were to assess the efficacy of BEBT-908 in brain orthotopic mouse models of hematological malignancies, to investigate its pharmacologic properties, and to elucidate the underlying mechanism of action...

Ivosidenib (Tibsovo® ), a first-in-class, oral small molecule, potent and selective inhibitor of mutant isocitrate dehydrogenase 1 (mIDH1), is approved in the EU and USA for the treatment of adults with pretreated, advanced, mIDH1 cholangiocarcinoma (CCA). It is presumed to exert its cytostatic effects in this setting by suppressing 2-hydroxyglutarate, an oncometabolite produced by mIDH1 that impairs cellular differentiation and promotes tumorigenesis. In the multinational phase 3 ClarIDHy study in patients with pretreated, advanced mIDH1 CCA, monotherapy with ivosidenib once daily significantly prolonged progression-free survival (PFS) and almost doubled the disease control rate compared with placebo...

BACKGROUND: Cell-cycle regulators are mutated in approximately 40% of all cancer types and have already been linked to worse outcomes in non-small cell lung cancer adenocarcinomas treated with osimertinib. However, their exact role in osimertinib resistance has not been elucidated. OBJECTIVE: In this study, we aimed to evaluate how the CDK4/6-Rb axis may affect the sensitivity to osimertinib. METHODS: We genetically increased the level of CCND1 (Cyclin D1) and reduced the levels of CDKN2A (p16) in two different adenocarcinoma cell lines, PC9 and HCC827...

BACKGROUND: Poly (ADP-ribose) polymerase (PARP) inhibitors are a new maintenance therapy option for patients with ovarian cancer (OC). OBJECTIVE: To evaluate the efficacy and influencing factors of the novel PARP inhibitor niraparib for maintenance treatment of Chinese patients with advanced OC. PATIENTS AND METHODS: In this retrospective multicenter real-world study patients with advanced OC from 15 hospitals throughout China were enrolled...
