Maßnahmenbeschreibung |
Zeitfenster |
---|---|---|
Number of Patients With Objective Tumor Response
Zeitfenster: Up to 18 weeks
|
Clinical objective tumor response with 14 weeks of Neoadjuvant Letrozole combined with Bevacizumab was assessed using the following categories: Complete Response (CR): tumor is no longer visible. Partial response (PR): ≥ 50% decrease from baseline in the product of two perpendicular diameters, no new lesions. Progressive disease (PD): ≥ 25% increase of the product of two perpendicular diameters or new lesions. Stable Disease (SD): Neither CR, PR, or PD criteria met. Clinical tumor assessment was performed at baseline and every 2 weeks until week 18 prior to definitive surgery. |
Up to 18 weeks

Breast Conservation
Zeitfenster: Up to 14 weeks
|
To assess breast conservation (actual surgery performed and baseline feasible surgery) of 14 weeks of neoadjuvant letrozole combined with bevacizumab. At baseline and immediately prior to surgery, the investigator will record the extent of the least invasive feasible surgery option at that time point, according to the following categories: 1. Breast conserving surgery is feasible; 2. A mastectomy is needed; 3. Tumor is inoperable, but potentially operable after neoadjuvant treatment. Following surgery, the investigator will record the extent of the actual surgery performed according to the following categories: 1. Breast conserving surgery performed; 2. Mastectomy performed 3. No surgery performed (reason should be specified). |
Up to 14 weeks
|
Radiographic Tumor Response
Zeitfenster: 18 weeks
|
To assess radiographic tumor response after 14 weeks of Neoadjuvant Letrozole combined with Bevacizumab, mammogram were performed at baseline and at week 18 prior to definitive surgery. Tumors response was assessed using RECIST criteria RECIST: CR: Tumor is no longer visible PR: ≥ 30% decrease from baseline in the longest diameter, no new lesions PD: ≥ 20% increase in longest diameter recorded or new lesions SD: Neither CR, PR, or PD criteria met |
18 weeks
|
Pathologic Complete Response
Zeitfenster: Up to 18 weeks
|
To assess pathologic complete response after 14 Weeks of Neoadjuvant Letrozole combined with Bevacizumab, the pathologic response was determined on the surgically excised specimen at the time of definitive surgery. The size of the residual tumor would be measured grossly if possible and confirmed microscopically. The excised residual tumor was be assessed using RECIST criteria. RECIST: CR: Tumor is no longer visible PR: ≥ 30% decrease from baseline in the longest diameter, no new lesions PD: ≥ 20% increase in longest diameter recorded or new lesions SD: Neither CR, PR, or PD criteria met |
Up to 18 weeks
|
Tumor Response With Biological Correlates
Zeitfenster: 2 weeks
|
To correlate response with biological correlates detected at baseline and after 1 cycle of treatment with either Bevacizumab alone or Bevacizumab combined with Letrozole.
|
2 weeks
|
Drug Tolerability
Zeitfenster: Up to 18 weeks
|
To assess the tolerability of 14 weeks of Neoadjuvant Letrozole combined with Bevacizumab, individual toxicities were graded according to the National Cancer Institute (NCI) Common Toxicity Criteria (CTC) Version 3.0.
Information about all adverse events, whether volunteered by the subject, discovered by investigator questioning, or detected through physical examination, laboratory test or other means, were collected and recorded on the Adverse Event Case Report Form and followed as appropriate.
An adverse event (AE) is any undesirable sign, symptom or medical condition occurring after starting study drug (or therapy) even if the event is not considered to be related to study drug (or therapy).
Study drug (or therapy) includes the drug (or therapy) under evaluation, and any reference or placebo drug (or therapy) given during any phase of the trial.
AE's graded 3 or 4 would be considered serious and be reported as measures of tolerability.
