Table 3.

Allelic Frequencies and Corresponding Tumor Regression Grade.

	TS Allele
Tumor Regression Grade	2R or 3C	3G
1	19 (24)	9 (43)
2	33 (42)	11 (52)
1 & 2	52 (66)	20 (95)
3	27 (34)	1 (5)

Tumor Regression Grades can be divided into 1 (complete response), 2 (partial response), 1&2 (any response), and 3 (no response). 20 of the 21 total 3G alleles (95%) were observed in patients with a Tumor Regression Grade of 1 or 2, while only 1 (5%) were observed in patients with a grade of 3. Of the 79 2R and 3C alleles, 66% corresponded to a grade of 1 or 2, while 34% corresponded to a grade of 3.
