Surviving Twenty Years to Bone and Liver Metastatic Breast Cancer: A Case Reported by Treating Oncologists and the Patient Herself.

Introduction: Metastatic breast cancer (MBC) presents an enduring and significant challenge for affected women, requiring sustained commitment over the years. Case Presentation: This paper presents a case of a woman affected by bone and visceral MBC with a very long 20-year survival, excellent quality of life, and high resilience. She is now 51 years old and underwent quadrantectomy for breast cancer in 2005, and in 2013, she developed a recurrence with bone and liver metastases. Despite the widespread stage of the disease with visceral compromise, the patient was treated with a multidisciplinary approach that included surgery, chemotherapy, radiotherapy, hormone therapy, bone target agents, metabolic radiotherapy, and ozone therapy for medication-related osteonecrosis of the jaw. Multidisciplinary management results in a complete clinical and metabolic response to treatment in a visceral metastatic setting. Conclusion: This report supports the possibility of achieving unusual survival outcomes in patients with MBC. This study also highlights the importance of resilience in breast cancer patients who continue to manage their disease and pursue treatment for over 2 decades. Understanding these resilience factors can improve clinical practice and support patients' long-term care.
