Cook pasta in pot of boiling salted water until just tender but still firm to bite, stirring occasionally. Drain; return to pot.
Meanwhile, spoon off and discard fat from juices in skillet. Add cream to juices in skillet and boil until sauce is reduced to 21/2 cups and is thick enough to coat spoon, about 10 minutes. Stir in 2 tablespoons lemon juice, then chicken pieces. Stir over medium heat until heated through, adding more broth by 1/4 cupfuls to thin sauce as needed and adding more lemon juice by teaspoonfuls, if desired, about 5 minutes. Season with salt and pepper. Add chicken mixture to pasta in pot and toss to coat. Stir in basil. Transfer pasta to plates.
