Highlights
- Early detection and management of metastatic breast cancer can significantly improve patient quality of life.
- Comprehensive care, including psychosocial support, is crucial for addressing the complexities of MBC.
Summary and Overview
Metastatic breast cancer (MBC), or stage IV breast cancer, occurs when cancer spreads from the breast to distant organs like bones, lungs, liver, brain, skin, and lymph nodes. It is generally incurable, with treatment aimed at prolonging survival and maintaining quality of life. Common metastatic sites include bones (70%), lungs (60%), liver (50%), and brain (10–15%), each causing distinct symptoms such as bone pain, respiratory issues, abdominal discomfort, or neurological deficits. Metastases may remain dormant for years, necessitating ongoing monitoring. Diagnosis involves clinical evaluation, imaging (MRI, CT, PET), and biopsies. Psychological distress is common, highlighting the need for integrated psychosocial care. Treatment includes systemic therapies (chemotherapy, hormone therapy, targeted drugs, immunotherapy) and local palliative measures like radiation, all within a multidisciplinary framework.
Signs, Symptoms, and Diagnosis
Symptoms of MBC vary by metastatic site. Bone metastases cause pain, fractures, and hypercalcemia; lung metastases lead to cough and breathlessness; liver involvement may cause jaundice and fatigue; brain metastases result in headaches and neurological symptoms. Skin changes and lymphedema can also occur. Psychological symptoms such as anxiety and depression are frequent. Diagnosis relies on imaging—bone scans, CT, MRI, PET-CT—and biopsy to confirm metastases and subtype. Guidelines recommend tailored diagnostic strategies based on symptoms and suspected sites.
Disease Progression and Clinical Significance
Symptom progression in MBC varies widely, with physical and psychological burdens intensifying over time. Anxiety and depression affect 20–50% of patients, influenced by disease uncertainty and treatment effects. Early symptom recognition aids timely diagnosis and management, improving outcomes. Approximately 15% of patients present with metastatic disease initially (de novo MBC), underscoring the importance of symptom awareness for early detection.
Management and Treatment
Treatment focuses on symptom relief and quality of life, as MBC is incurable. Systemic therapies include chemotherapy, hormone therapy, targeted agents, and immunotherapy, tailored by cancer subtype. Local treatments like radiation provide palliation for painful metastases. Psychosocial support addressing anxiety, depression, and body image concerns is integral to care. Multidisciplinary approaches optimize symptom control and emotional well-being.
Prognosis and Psychosocial Aspects
While incurable, advances allow many patients to live longer with manageable symptoms. Prognosis depends on individual factors and treatment response. Psychological distress, including depression and stigma, significantly impacts quality of life. Interventions such as supportive psychotherapy, cognitive behavioral therapy, and mindfulness can alleviate psychosocial difficulties. Special attention is needed for elderly patients, with tailored programs and e-health resources improving coping and adjustment.
Patient Support and Resources
Effective support addresses both physical symptoms and emotional health. Screening identifies distress in 20–35% of patients, prompting early intervention. Healthcare providers should engage patients in open discussions about body image and mental health using approaches like The Three C’s (common, concerns, consequences). Integrating mental health assessment into treatment plans and considering social factors improves adherence and outcomes. A holistic, multidisciplinary approach ensures comprehensive care throughout the disease course.
