Patrick Swayze, who revealed in March he's battling pancreatic cancer, is happy to report he's continuing to respond to treatment.

The Dirty Dancing star tells People he and wife Lisa Niemi--both of whom were spotted taking in the L.A. Lakers' playoff victory Friday at Staples Center (seen above)--have been keeping busy jetting back and forth between L.A. and their ranch in New Mexico and they just returned home from a weekend trip to Reno to celebrate Lisa's birthday.

"I took her jewelry shopping at Kenny G & Company and [we] were able to find her something really special and much deserved! In the meantime, I am continuing treatment at Stanford [University Medical Center] and the great news is I continue to respond well."
