Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
A stopping rule is applied when ≥ 4 patients out of 8 lack FES-uptake, despite a positive staining for ERα on biopsy. When 4 patients out of 8 patients with an ERα-positive immunohistochemical staining don’t show FES uptake in tumor lesions, the 95% confidence interval of the sensitivity of FES-PET for ERα-positive lesions is <85%. |
