The role of entrance channel for reactions with massive nuclei is discussed by comparison of experimental data of reactions with different mass (charge) asymmetry and leading to different isotopes of the superheavy element Z = 112. Three stages (capture, complete fusion, and formation of evaporation residues) of the so called "cold" and "hot" fusion reactions are considered for <SUP>70</SUP>Zn + <SUP>208</SUP>Pb and <SUP>48</SUP>Ca + <SUP>238</SUP>U reactions which were used to synthesize superheavy elements Z =112. It is shown that the collisions by the orientation angles 30°<α<SUB>P</SUB>< 60° for projectile and 30°<α<SUB>T</SUB><45° for the target nucleus lead to the largest cross section in synthesis of superheavy element in the <SUP>48</SUP>Ca + <SUP>238</SUP>U reaction at E<SUP>*</SUP><SUB>CN</SUB> = 35 MeV.
