S0226 Anastrozole With or Without Fulvestrant as First-Line Therapy in Postmenopausal Women With Metastatic Breast Cancer

Draft scope assessment: unclear. Attached because the study's own record describes metastatic disease. The study was not selected for this indication by its sponsor, and its eligibility has not been reconciled against this page in full. Found because this study's registry identifier is printed in an FDA approval notice, an FDA product label or an NCI summary held by this site. The citing document and the exact position of the identifier inside it are recorded. Being cited is not a statement that the study supports this treatment.

Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target measurable lesions over the smallest sum observed (over baseline if no decrease during therapy) using the same techniques as baseline. Unequivocal progression of non-measurable disease in the opinion of the treating physician. Appearance of any new lesion/site. Death due to disease without prior documentation of progression and without symptomatic deterioration. From date of randomization to time of first documentation of progression, symptomatic deterioration or death due to any cause. Patients last known to be alive and progression free are considered at last date of contact.

Adverse Events (AEs) are reported by CTCAE version 3.0 terminology. For each patient, worst grade of each event type is reported. Grade3 (Severe), Grade4 (Life-threatening), Grade 5 (Fatal)

Eligible patients who had received the protocol treatments were included in the adverse event summaries. Any CTCAE 3.0 event of Grade 3 (serious), Grade 4 (life threatening) or Grade 5 (fatal) which were deemed to be related to protocol treatment are included.

Time to Tumor Progression
endpoint definition
Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target measurable lesions over the smallest sum observed (over baseline if no decrease during therapy) using the same techniques as baseline. Unequivocal progression of non-measurable disease in the opinion of the treating physician. Appearance of any new lesion/site. Death due to disease without prior documentation of progression and without symptomatic deterioration. From date of randomization to time of first documentation of progression, symptomatic deterioration or death due to any cause. Patients last known to be alive and progression free are considered at last date of contact.
time origin
Every 4 weeks while on treatment. Then every 3 months until progression, then six months for two years then annually until four years or until death, which ever occurs first.
