The vacuum-condensate dependence of nucleon parameters is investigated within QCD sum rules. It is shown that, without allowance for radiative corrections, a solution to the sum-rule equations exists only under stringent constraints on condensate values. There is only an unphysical solution beyond the region specified by these constraints. It is found that the nucleon-mass value is stabilized upon taking into account radiative corrections.
