Objective: Colorectal cancer is a malignant tumor with high incidence and mortality rates worldwide, accounting for approximately 10% of all cancer-related deaths. Although various surgical treatments and chemotherapy regimens are currently available, the likelihood of recurrence and metastasis varies by disease stage. In particular, cases with serosal invasion or multiple lymph node metastases are classified as high-risk, and in such patients, it is important to establish appropriate treatment and management strategies considering factors such as lymphovascular invasion (LVI), perineural invasion (PNI), and carcinoembryonic antigen (CEA) levels. Recently, it has been suggested that Ortho-Cellular Nutrition Therapy (OCNT) may support recovery and symptom management after cancer treatment by improving overall cellular function.
Case Report: A Korean man in his 50s was undergoing colectomy and adjuvant chemotherapy after being diagnosed with stage IIIC colorectal cancer. During treatment, he reported symptoms causing discomfort in daily life, including fatigue and weakness, anxiety, numbness in the hands and feet, loose stools, facial pallor, and weight loss. Accordingly, OCNT including anthocyanins, omega-3 fatty acids, selenium, zinc, vitamin D, resveratrol, butyrate-producing bacteria, and curcumin was prescribed. As a result, his symptoms gradually eased; during OCNT, CEA levels remained stable and decreased, and he was assessed as having no recurrence or metastasis.
Conclusion: Although limited to a single patient, this case is considered to demonstrate the potential utility of OCNT as an adjunct to chemotherapy, based on notable improvement in bothersome symptoms, a stable clinical course, and the medical team’s assessment in a patient with high-risk colorectal cancer.
