Introduction

• Non-small cell lung cancer (NSCLC) accounts for ~85% of lung cancers and remains the leading cause of cancer death.
• Surgery is curative for early-stage disease, but recurrence rates remain high.
• CheckMate-816 trial established neoadjuvant chemo-immunotherapy (chemo-IO) as a new standard for resectable NSCLC, demonstrating improved pathologic response and event-free survival.
• PACIFIC trial showed the survival benefit of consolidative immunotherapy after chemoradiotherapy (chemo-RT) in unresectable stage III NSCLC, highlighting the synergy between radiation and immune checkpoint blockade.
• Despite these advances, there is little comparative data on the role of chemo-IO versus chemo-RT in the neoadjuvant, operable setting.
• Objective: To compare …

Introduction

- Flexible nasopharyngolaryngoscopy (NPL) is a core diagnostic and procedural skill in otolaryngology, radiation oncology, and related specialties. Early mastery is essential for safe patient care, but traditional training is limited by:

• Reliance on patient encounters, which may cause discomfort and restrict practice opportunities.
• High cost of commercial simulators(often $3,000–$5,000), restricting access across many programs.
• Lack of anatomical accuracyin available models, limiting their educational value.

- Gap: There is currently no accessible, anatomically faithful, and affordable tool for widespread trainee use.

- Objective: To design, fabricate, and validate a low-cost, anatomically accurate 3D-printed simulator for training in flexible NPL

Organ-Specific Dosimetry Following Radiopharmaceutical Therapy For Metastatic Prostate Cancer, Frank J. Arturi, Nilanjan Haldar, Shray Jain, Gia Nguyen, Jessie Dinome, Firas Mourtada, Lydia J. Wilson, Phd

Introduction

• Radiopharmaceutical Therapy (RPT) uses radioactive agents to target cancer at the cellular level
• Lu-177 targeting prostate-specific membrane antigen (PSMA), known as 177Lu- PSMA-617, can be used to treat metastatic, castration-resistant prostate cancer (mCRPC)
• 177Lu-PSMA-617 treatments use a standard dose and treatment regimen for all patients
• Patients exhibit different side effects and tumor response during treatment

Background

• Radiation-induced pulmonary fibrosis (RIPF) is a frequent outcome of thoracic radiation therapy, constraining safe tumor radiation dosage. Various animal models, such as mice, rats, and pigs, have been devised to study RIPF
• Current methods for inducing lung fibrosis in mice involve whole lung irradiation with doses between 2-20 Gy. These methods used fixed anterior and posterior (AP/PA) x-ray beams at 0º and 180º with analysis typically commencing 24 to 52 weeks post-radiation
• Current methods are unrepresentative of modern radiation therapy techniques and are limited by the associated long latency of RIPF
