- In this work, we systematically investigate the mass spectra of fully heavy pentaquark states $QQQQ\bar{Q}$ within the framework of QCD sum rules. Employing three configurations of interpolating currents, we obtain the following mass predictions: for the $cccc\bar{c}$ states, the masses are determined to be $7.79^{+0.18}_{-0.17}$ GeV, $7.76^{+0.23}_{-0.18}$ Gev, $7.81^{+0.17}_{-0.18}$ GeV; while for the $bbbb\bar{b}$ states, the corresponding masses are calculated as $22.35^{+0.19}_{-0.19}$ GeV, $22.27^{+0.22}_{-0.22}$ GeV, $22.37^{+0.18}_{-0.20}$ GeV, respectively.
