Title:
Prognostic and predictive role of RBsig and CCNE1/RB1 gene-expression signatures in patients with advanced breast cancer treated with palbociclib in combination with endocrine therapy in the PALOMA-2 and 3 trials
Published date:

Excerpt:
...in PALOMA- 3 patients with CCNE1/RB1 high tumors treated in the palbociclib arm showed a significantly worse outcome compared to those with CCNE1/RB1 low but this effect was not observed in those treated in the control arm [HR 1.6 (95% CI 1.1- 2.5) p= 0.03 for palbociclib arm; HR 1.2 (95% CI 0.7, 1.9) p=0.5 for control arm].
