Breast cancer is frequently accompanied by chronic inflammation, malnutrition, and reduced quality of life, all of which may compromise treatment response and clinical outcomes. Nutritional interventions with immunomodulatory and anti-inflammatory properties have the potential to improve these conditions. Channa striata is rich in high-quality protein, albumin, and essential amino acids that support nutritional recovery and tissue repair, while Curcuma contains curcumin, a bioactive compound with well-established anti-inflammatory and antioxidant effects. This study aims to evaluate the effect of combined Channa striata and Curcuma supplementation on nutritional status, serum interleukin-6 (IL-6) levels, and quality of life in patients with breast cancer undergoing treatment. The findings are expected to provide evidence for the use of this nutritional supplementation as a complementary strategy to improve clinical outcomes, reduce systemic inflammation, and enhance the overall well-being of breast cancer patients.
