Authors' objectives: To assess the safety, effectiveness, cost-effectiveness and organisational issues of targeted therapies in combination with hormonal therapy as a first-line treatment for HR+, HER2-, metastatic breast cancer.
Authors' results and conclusions: A total of 986 records were identified through database and other sources. Fourteen studies were included in this review: three network meta-analysis, two systematic reviews with meta-analysis, one randomized control trial, six cost-effectiveness analyses, and two budget impact analysis. The evidence suggested that combination of CDK 4/6 inhibitors (palbociclib, ribociclib or abemaciclib) with AI resulted in longer PFS, higher overall response rate (ORR) and clinical benefit (CB) compared to AI monotherapy and fulvestrant-based therapies. When compared to chemotherapy agents, the combination treatment also showed improvement in PFS. Palbociclib, ribociclib and abemaciclib (in combination with AI) demonstrated similar efficacy as a first-line treatment for HR+, HER2-, metastatic breast cancer. In terms of safety, grade III or IV treatment-related side effects were significantly higher in patients who received combination treatment compared to AI monotherapy with commonly reported side effects of neutropaenia, leukopaenia, and anaemia. As for cost-effectiveness, ribociclib plus letrozole was a cost-effective therapy option compared to palbociclib plus letrozole. The estimated ICER varied across countries for both treatment options with different perspectives and thresholds
Authors' recomendations: Combination of CDK 4/6 inhibitors with AI is recommended as a first-line treatment for HR+, HER2-, metastatic breast cancer. Ribociclib plus letrozole might be a cost-effective options for this population.
