This narrative review examines the integration of precision oncology and psycho-oncology in breast cancer treatment, highlighting the impact of psychological factors on clinical outcomes despite advances in biomarker-driven therapies. The review synthesizes evidence on molecular stratification, targeted treatments, psychiatric comorbidity, psychological profiles, and psycho-oncological interventions. It concludes that integrating psychological screening and tailored interventions into routine clinical pathways is crucial for optimizing adherence, quality of life, and long-term outcomes.
Integrating psycho-oncological assessment and intervention into breast cancer treatment pathways may improve patient adherence, quality of life, and long-term outcomes.
Breast cancer represents a paradigmatic model of precision oncology, with treatment strategies increasingly guided by molecular profiling and biomarker-driven targeted therapies. Despite these advances in biological personalization, clinical outcomes remain strongly influenced by psychological and psychiatric factors that are still insufficiently integrated into oncological decision-making. This gap underscores the need for a broader, person-centered model of personalization that extends beyond tumor biology. This narrative review synthesizes current evidence on contemporary personalized strategies in breast cancer management, with a specific focus on the integration of precision oncology and psycho-oncology. A structured literature search was conducted across major biomedical databases to identify studies addressing molecular stratification, targeted treatments, psychiatric comorbidity, psychological profiles, and psycho-oncological interventions relevant to treatment personalization. While molecular classification and biomarker-guided therapies have substantially improved breast cancer outcomes, high rates of depression, anxiety, psychological distress, and maladaptive coping styles are consistently reported across disease stages. These psychological and psychiatric dimensions significantly influence treatment adherence, tolerability, quality of life, and ultimately clinical outcomes. Growing evidence supports the systematic use of psychological screening tools and tailored psycho-oncological interventions, both psychological and pharmacological, as integral components of personalized cancer care. Integrated care models combining oncological and psycho-oncological expertise are associated with improved patient-reported outcomes and may enhance overall therapeutic effectiveness. True personalization in breast cancer treatment extends beyond biological precision and requires the structured integration of psycho-oncological assessment and intervention into routine clinical pathways. Bridging precision oncology and psycho-oncology enables a more comprehensive, patient-centered approach, optimizing adherence, quality of life, and long-term outcomes. Future strategies should prioritize multidisciplinary models of care and the development of integrated clinical frameworks to achieve genuinely personalized breast cancer management.
