COMC calls them 1997-98 Upper Deck European Sticker http://www.comc.com/Cards/Basketball/1997-98/Upper_Deck_European_Stickers,ot. I've also seen them referred to as Upper Deck Italian Stickers, Upper Deck International Stickers, Upper Deck Basketball Italian Stickers, Upper Deck Basketball International Stickers, Upper Deck Basketball European Stickers. Seems there's no concensus. The box and pack aren't much help. The Italian address on the back of the sticker is the only indication to be European. If I were to choose a name for the database it'd be "1997-98 Upper Deck NBA Stickers (European)". The only checklist I found so far does not have Teams. So it'll take some time to add Teams to the 332 stickers. But before I do that I'll keep searching.
Someday my cards may double in value and then be worth half of what I paid for them.
