Table 2. Correlation between MED12 exon 2 mutation status and patient age and tumor size in patients with fibroepithelial tumors.

	Age (Mean ± SD) MED12 mutant	n	Age (Mean ± SD) MED12 wild-type	n	P value
Fibroadenoma	31.8 ± 1.9	17	37.1 ± 3.7	9	0.158
Benign PT	42 ± 2.2	22	36.3 ± 8.1	3	0.404
Borderline PT	49.3 ± 4.5	7	44.5 ± 2.5	2	0.604
	Tumor size (cm) (Mean ± SD) MED12 mutant	n	Tumor size (cm) (Mean ± SD) MED12 wild-type	n	P value
Fibroadenoma	1.7 ± 0.2	17	2.2 ± 0.3	9	0.168
Benign PT	2.3 ± 0.2	22	2.4 ± 1.3	3	0.899
Borderline PT	5.8 ± 1.2	7	5.8 ± 3.1	2	0.986

Student's t-tests, two-tailed. PT, phyllodes tumor; SD, standard deviation. Malignant PTs were excluded from this comparison due to small sample size and the low frequency of MED12 mutations.
