Objective: Several clinical trials examining treatment strategies for advanced laryngeal cancer have demonstrated that concurrent chemoradiotherapy is the most effective treatment for improving the patient response to radiotherapy and laryngeal preservation. We evaluated a new regimen of S-1/CDGP(Nedaplatin) with radiotherapy (RT), and established that it represented an effective new treatment option that allowed for the preservation of the larynx.
Methods: A total of 16 patients with stage II to IV laryngeal cancer(excluding T4 stage)who had been treated at our institution from 2001 to 2007 were recruited for the present study. All patients had histologically-confirmed squamous cell carcinomas.
Results: The administration of S-1/CDGP/RT led to a complete response (CCR) in all patients with stage II or IV disease, with preservation of the larynx in all of these cases. For patients with stage III disease, 6 (85%) experienced CR, and 1 patient (15%) had a partial response. The laryngeal preservation rate for these patients was 85%. Severe toxicities, i. e., neutropenia, thrombocytopenia, and dermatitis of grade 3, were observed. The overall five-year survival rate was 72%, and the disease specific survival rate was 92%.

Importance: The phase 3 randomized EMBARK trial evaluated enzalutamide with or without leuprolide in high-risk nonmetastatic hormone-sensitive prostate cancer. Eligibility relied on conventional imaging, which underdetects metastatic disease compared with prostate-specific membrane antigen-positron emission tomography (PSMA-PET).
Objective: To describe the staging information obtained by PSMA-PET/computed tomography (PSMA-PET/CT) in a patient cohort eligible for the EMBARK trial.

Purpose: Up to 50% of high-risk non-muscle invasive bladder cancer (HR-NMIBC) patients fail Bacillus Calmette-Guérin (BCG) treatment, resulting in a high risk of progression and poor clinical outcomes. Biomarkers that predict outcomes after BCG are lacking. The antitumor effects of BCG are driven by a cytotoxic T cell response, which may be controlled by immune checkpoint proteins like Programmed Death Ligand 1 (PD-L1).

Although immune checkpoint inhibitors have changed the treatment paradigm for non-small cell lung cancer (NSCLC), not all patients benefit from them. Therefore, there is an urgent need to explore novel immune checkpoint inhibitors. Neuropilin-1 (Nrp-1) is a unique immune checkpoint capable of exerting antitumor effects through CD8 T cells.

Background: Esophageal cancer (ESC) is an aggressive disease which often presents at an advanced stage. Despite trimodal therapy, 40-50% patients can develop metastatic disease by 18 months. Identification of patients at risk for metastatic spread is challenging with need for improved prognostication.
