This phase III trial compares the effect of dose-escalated radiation therapy to usual care in patients with locally advanced unresectable pancreatic ductal adenocarcinoma who have received an initial 4-8 months of chemotherapy. Usual care options include additional chemotherapy, observation, or standard lower-dose radiation therapy. These treatments may delay tumor growth but have not been shown to improve survival. Radiation therapy uses high energy X-rays to kill cancer cells and shrink tumors. Dose-escalated radiation therapy involves the precise delivery of higher doses to the tumor, often over a shorter period of time. This trial assesses whether using dose-escalated radiation therapy can prolong survival.
PRIMARY OBJECTIVE: I. To evaluate whether dose-escalated radiation therapy (RT) improves 3-year overall survival (OS) compared to standard treatments without dose-escalated RT, in locally advanced pancreatic cancer patients without radiographic progression and with biochemical response after an initial interval of chemotherapy. SECONDARY OBJECTIVES: I. To evaluate and compare local progression between the two treatment arms. II. To evaluate and compare progression-free survival (PFS) between the two treatment arms. III. To evaluate and compare chemotherapy-free interval between the two tre…
Inclusion Criteria: * At time of enrollment, the patient must have received 4-8 months of active chemotherapy with FOLFIRINOX or NALIRIFOX or gemcitabine/nab-paclitaxel. Patients are permitted to receive more than 1 type of chemotherapy for reasons other than radiographic progression by Response Evaluation Criteria in Solid Tumors (RECIST) (i.e. chemotherapy regimen switch is allowed for toxicity, and/or switch is allowed for toxicity and/or CA19-9 level not declining). Patients are allowed to receive chemotherapy after restaging scans, as long as 1) restaging scans are performed after at lea…
