  • * Percentages of pancreatic and carcinoid NETs do not necessarily add up to 100% because sometimes there is overlap in and/or inconsistent/incomplete recording of location and/or histology.

  • These studies reported median activity level.

  • These studies provided a follow-up range, but didn’t explicitly state when RECIST was recorded. In most studies best response was given.

  • § This study reported RECIST within 6 mo after treatment.

  • All response rates are per RECIST, except the Kennedy study, which used RECIST or World Health Organization criteria.

  • N/A: not available; IAT: intraarterial therapies
