Ovarian Cancer: Time to Question Why Certain Federally Funded Cancer Trials Have Been, or Are Being, Done



Opinion (Markman)

  This commentator is unaware of the specific circumstances surrounding the decision to design the study as reported,1 but the effect of the decision is clearly evident and distressing.
 Overall, there was no difference in progression-free survival between the study arms (weekly vs every-3-week paclitaxel),1 in striking contrast to the previously noted Japanese data.2 
 What can we conclude from the conduct of this large US government–funded, multicenter, multiyear, Phase III, randomized trial? Essentially nothing, despite the fact almost 700 patients were entered at considerable taxpayer expense.
