Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1.Cohort of patients with unresectable pancreatic cancer Pre-treatment ctDNA identification rate 2.Cohort of patients with resectable pancreatic cancer Success rate of creation of a personalized panel using tumor tissue specimens obtained by EUS-FNA/FNB | — |
Secondary
| Measure | Time frame |
|---|---|
| 1.Cohort of patients with unresectable pancreatic cancer Pretreatment ctDNA detection rate for each disease stage (stage III and stage IV) Association of pretreatment ctDNA detection rate and the treatment efficacy Association of pretreatment serum tumor marker levels, ctDNA levels and treatment efficacy Association of the time-course of changes of the pretreatment serum tumor marker levels and ctDNA positivity and the treatment efficacy Differences in OS and PFS between the patients in whom the personalized panel can be created and those in whom it cannot be created 2.Cohort of patients with resectable pancreatic cancer Rate of ctDNA positivity for each cancer stage (stage IA-stage IIB) before neoadjuvant chemotherapy (NAC) and 4 weeks after surgery. Association of preoperative ctDNA before NAC and overall survival Association of postoperative ctDNA before adjuvant chemotherapy (AC) and overall survival Proportion of ctDNA positivity at the time of recurrence detected by diagnostic imaging. Association of serum tumor marker levels and recurrence free survival (RFS), ctDNA positivity an d RFS at the timepoints before NAC and before AC. Differences in OS and PFS between the patients in whom the personalized panel can be created and those in whom it cannot be created To investigate the lead time from ctDNA detection to recurrence detected by diagnostic imaging. | — |
