Welcome, Deep Throat.
I am very sorry that your diagnosis took so long: my husband's took 5 months which was bad enough. If you Google 'HIV HPV oropharyneal cancer' and then click on the scholarly articles results, you will get some limited information, including a 2009 article by OCF's great friend, Dr. Maura Gillison. Unfortunately, this information is NOT as widely recognized as it should be.
