- *The median expression level was used as the cutoff. Low PRDM2 mRNA levels were defined as values below the 50th percentile of the 12 patients; values at or above the 50th percentile were classified as high levels.
- **The median serum PRL level was used as the cutoff: 435 μg/ml. Low serum PRL levels were defined as values below the 50th percentile of the 12 patients; values at or above the 50th percentile were classified as high levels.
- ***Recurrence was defined as the discovery of an elevated PRL level at any time in the postoperative surveillance period after an initial remission.
- ****Resistant tumors to BRC were defined as those from patients whose serum PRL levels remained abnormally high after at least 3 months of treatment with a daily dose of 15 mg BRC.
