LXDE/LXQT distro with 5 years support?

Does a distro exist based on (pre-installed) LXDE/LXQT which has 5 years support minimum. I have seen Lubuntu which only has 3 years support. I am basically looking for a very stable desktop distro which is not a rolling release distro which has predictable scheduled releases every 5 years or more.
