K-ras gene status and response to therapy

Group K12-ras gene mutation/total
(%)
Positive therapy response (%) P
Value
Mutant Wild type
Controls 0/75 (0) __ __ __
MGUS 1/66 (1.5) __ __ __
MM 20/73 (27.4) 26.9 58.3 0.01

Statistical significance for K12-ras gene mutation: Control vs MGUS p = 0.95, Control vs MM p = 0.0001, MGUS vs MM p < 0.0001, Positive therapy response: minor response and no change disease (see Methods).
