Objective: Breast cancer is one of the most common malignant tumors affecting women worldwide. In clinical practice, breast cancer is diagnosed, and its subtype is determined using imaging studies and histopathologic examinations. When tumor cells are negative for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) protein expression, the disease is diagnosed as triple-negative breast cancer (TNBC). TNBC is the most heterogeneous subtype of breast cancer, has markedly limited treatment options, and is associated with a poor prognosis. Therefore, although novel therapeutic approaches are being introduced to address this unmet need, the long-term evidence base remains insufficient, and continued investigation of new treatment strategies is warranted.
Case Report: This case involved a Korean woman in her 40s who was diagnosed with TNBC. After the diagnosis, she underwent chemotherapy and radiotherapy and continued to report treatment-related fatigue, lymphedema, and pain. Following the completion of anticancer therapy, Ortho-Cellular Nutrition Therapy (OCNT) was administered to promote overall symptom improvement using omega-3 fatty acids, bromelain, chlorella, minerals, anthocyanins, fucoidan, beta-glucan, vitamin D, heme iron, and Ginkgo biloba leaf extract. Consequently, the patient’s symptoms showed a clinically meaningful improvement, and approximately 3 years and 10 months after initiation of OCNT, she was evaluated by the treating clinicians as having achieved complete remission.
Conclusion: Because this report describes a single patient, it is limited in its ability to support applying the same OCNT regimen to all patients with TNBC. Nevertheless, the present case is noteworthy in that an OCNT prescription tailored to the patient’s clinical condition was associated with improvement in cancer treatment–related symptoms and achievement of complete remission.
