The relevant distinction between “progression” in ovarian cancer drug trials and the clinical decision to change therapy - Markman (very short abstract)

abstract: "It is rational to suggest that the decision to alter treatment in advanced ovarian cancer should be based on the totality of evidence that the disease is worsening, on patient tolerability of the therapy, and on a determination that the current regimen is providing no benefit or unacceptably limited benefit to the specific individual. Knowledge of an objective measure of “progression” should play an important, but not a singular, role."
