Artificial intelligence-generated targets and inter-observer variation in online adaptive radiotherapy of bladder cancer.

Background And Purpose: Daily target re-delineation in online adaptive radiotherapy (oART) introduces uncertainty. The aim of this study was to evaluate artificial intelligence (AI) generated contours and inter-observer target variation among radiotherapy technicians in cone-beam CT (CBCT) guided oART of bladder cancer.

Materials And Methods: For each of 10 consecutive patients treated with oART for bladder cancer, one CBCT was randomly selected and retrospectively included.

AXL Inhibition Improves the Antitumor Activity of Chimeric Antigen Receptor T Cells.

The receptor tyrosine kinase AXL is a member of the TYRO3, AXL, and proto-oncogene tyrosine-protein kinase MER family and plays pleiotropic roles in cancer progression. AXL is expressed in immunosuppressive cells, which contributes to decreased efficacy of immunotherapy. Therefore, we hypothesized that AXL inhibition could serve as a strategy to overcome resistance to chimeric antigen receptor T (CAR T)-cell therapy.

Online adaptive radiotherapy of urinary bladder cancer with full re-optimization to the anatomy of the day: Initial experience and dosimetric benefits.

Background And Purpose: Online adaptive radiotherapy (oART) potentially reduces the dose to organs at risk (OARs) as the planning target volume (PTV) margins are reduced compared to a non-adaptive approach (non-ART). This study evaluates the feasibility and dosimetric impact of cone-beam computed tomography (CBCT)-guided oART of urinary bladder cancer for the first patients treated, using patient-specific margins.

Materials And Methods: Sixteen consecutive patients with muscle-invasive bladder cancer received two or more (median = 23) fractions as oART, and remaining fractions as non-ART.

Single-Cell Proteomic Profiling Identifies Combined AXL and JAK1 Inhibition as a Novel Therapeutic Strategy for Lung Cancer.

Cytometry by time-of-flight (CyTOF) simultaneously measures multiple cellular proteins at the single-cell level and is used to assess intertumor and intratumor heterogeneity. This approach may be used to investigate the variability of individual tumor responses to treatments. Herein, we stratified lung tumor subpopulations based on AXL signaling as a potential targeting strategy.

Vinflunine/gemcitabine versus carboplatin/gemcitabine as first-line treatment in cisplatin-ineligible patients with advanced urothelial carcinoma: A randomised phase II trial (VINGEM).

Background: The present study (VINGEM) is the first randomised trial comparing vinflunine/gemcitabine (VG) to standard carboplatin/gemcitabine (CG) in patients with advanced urothelial carcinoma (aUC) ineligible for treatment with cisplatin.

Patients And Methods: Patients with aUC, creatinine clearance 30-60 ml/min, performance status ≤1 and no prior chemotherapy for metastatic disease were randomised to the experimental arm (vinflunine 280 or 250 mg/m day 1, gemcitabine 1000 mg/m days 1 and 8, q21 days) or the control arm (carboplatin AUC 4.5 day 1, gemcitabine 1000 mg/m days 1 and 8, q21 days).
