The greatest power of a prime p dividing the natural number n will be denoted by \(n_p\). For a set of primes \(\pi \) and a natural number n we will denote \(n_{\pi }=\prod _{p\in \pi }n_p\). Let G be a finite group with trivial center, and \(p,q>5\) be distinct prime divisors of |G|. We prove that if for every nonunity conjugacy classes size \(\alpha \), it is true that \(\alpha _{\{p,q\}}\in \{p^n,q^m,p^nq^m\}\), where n and m depend only on p and q, then \(|G|_{\{p,q\}}=p^nq^m\), and \(C_G(g)\cap C_G(h)=1\) for every p-element g and every q-element h.
