“…Patients were most frequently diagnosed with pancreatic cancer ( n = 10) 31,35,36,40,41,50,52,56,61,64 and non‐small cell lung cancer ( n = 9) 25,29,35,36,39,55–57,62 . Eight studies 25,29,38,39,45,47,63,64 used stage III or IV as inclusion criterion for specifying the status of disease, while others described the stage of disease eligible for ECP studies as “advanced” or “incurable.” 26,27,31,32,35,37,40–42,44,48–50,52,54–61 Other criteria amenable for EPC in the studies were the line of therapy or treatment 30,33,34,45,52 or resistance to a certain regime 31,63,64 . Two studies used a symptom burden over 33% regarding four symptoms, one symptom with at least 50% burden measured by the EORTC‐QLQ‐C30, 38 or cancer‐related pain higher than 3 measured by the Brief Pain Inventory, 61 to determine eligibility for the EPC intervention.…”
