Assessment of the DaRT seed placement within the tumor or less than 5 mm from the tumor using CT imaging on the day of DaRT insertion.
Assessment of the frequency, severity and causality of acute AEs and SAEs related to DaRT seeds insertion. AEs and SAEs will be assessed and graded according to Common Terminology and Criteria for Adverse Events (CTCAE) version 5.0
Assessment of the frequency, severity and causality of Late AEs and SAEs related to DaRT seeds insertion. AEs and SAEs will be assessed and graded according to Common Terminology and Criteria for Adverse Events (CTCAE) version 5.0. The follow up will be carried out by phone calls every 2 months during the time between 3 to 24 months after DaRT seeds insertion
Assessment of the objective response rate (ORR) following DaRT seeds insertion using CT scan
Measuring CA19-9 as a marker to tissue damage. Elevation during treatment, and reduction as a result of tumor ablation. Serum levels of CA 19-9 can be measured using chemiluminescent assay on an Unicel DxI 800 analyzer (BeckmanCoulter, Brea, CA, USA).
Assessment of the overall survival (OS) following DaRT seeds insertion
Stent durability will be assessed by the time elapsed from DaRT insertion to the need for follow-up referral for ERCP for stent change due to tumor ingrowth
Assessment of patient reported health-related Quality of Life (QoL) outcomes after DaRT treatment, using QoL questionnaires EORTC-QLQ-C30 (version 3.0). Scale range in score from 0 (best) to 100(worst).
Assessment of patient reported health-related Quality of Life (QoL) outcomes after DaRT treatment, using QoL questionnaires QLQ-PAN26. The module comprises 26 questions assessing pain, dietary changes, jaundice, altered bowel habit, emotional problems related to pancreatic cancer, and other symptoms (cachexia, indigestion, flatulence, dry mouth, taste changes).
