PULSAR in Systemic Therapy for Pancreatic Cancer

Pancreatic cancer remains one of the malignancies with the lowest survival rates, largely due to late-stage diagnosis and the difficulty of achieving curative resection. A substantial proportion of patients present with locally advanced, unresectable disease at the time of diagnosis, making intensive systemic therapy the current standard of care. For selected patients, radiation therapy (RT) is integrated to improve local control. Local progression in the pancreas can lead to severe complications, including intractable pain, gastric outlet obstruction, and biliary obstruction, which ultimately contribute to morbidity, deteriorating quality of life, and reduced overall survival. Therefore, effective local therapy remains a critical component of comprehensive management. However, delivering high-dose radiation to pancreatic tumors is particularly challenging because the pancreas is anatomically surrounded by radiation-sensitive organs such as the stomach, duodenum, liver, kidneys, and small bowel. Conventional RT and stereotactic body RT (SBRT) have both been limited by gastrointestinal toxicity, making substantial dose escalation difficult and resulting in modest local control outcomes. Previous studies combining systemic therapy with radiotherapy have shown signals of improved local progression-free survival (LPFS) and progression-free survival (PFS). Still, results have been inconsistent across trials, highlighting the need for rigorous clinical evaluation of the true ther…
