My campaigns have been run in the Planescape 'setting' with sidetreks to FR, Athas, etc but largely staying on the planes. But while I've used the setting material as a basis, I've never actually run a published adventure. I'll use or take inspiration from published adventures if they're detailed and fluffy enough, but I won't run a prepackaged module as is.
I've used material from one or two of them though, in the sense of cannibalizing locations and such described in them. I've used Tchian Sumere (Orcus/Tenebrous's fortress in Negative Energy) from 'Dead Gods' along with the dead prime material world of Renais, and I've used the Kyton fortress of Panos Qytel in Jangling Hiter from 'Tales from the Infinite Staircase', but a large portion of anything I've done has used stuff I've created from whole cloth, or elaborated upon from base setting material.
Only one of the Baernaloths in the last campaign I ran were not created by me, and Daru Ib Shamiq (from 'Hellbound') was reinterpreted in a pretty severe way when I used him.
