Studysummary In this extended follow-up of the PALOMA-2 trial, no significant differences in overall quality of life were observed between first-line treatments for metastatic breast cancer, but palbociclib plus letrozole showed some benefits regarding side-effects and hair loss. Our plain-language summary of this paper — not a Tressless recommendation.
The extended follow-up of the PALOMA-2 trial, involving 666 women with ER+/HER2− metastatic breast cancer, evaluated the long-term effects of palbociclib plus letrozole on health-related quality of life (HRQoL). The study found that HRQoL was maintained in patients receiving palbociclib plus letrozole, with no significant differences in overall change from baseline in FACT-B and EQ-5D-3L scores compared to placebo plus letrozole. However, patients in the palbociclib group reported fewer side effects and less hair loss. Although the time to deterioration in quality of life was shorter for those with disease progression, palbociclib plus letrozole remains an effective long-term treatment option for maintaining quality of life in this patient population.
