Metastatic colon cancer treated using traditional Chinese medicine combined with chemotherapy: A case report

BACKGROUND: Colon cancer (CC) is one of the leading causes of cancer-related morbidity and mortality worldwide. Traditional Chinese medicine (TCM) is widely used in the treatment of various chronic diseases. CC easily metastasizes and results in high morbidity and mortality rates. CASE SUMMARY: A 71-year-old man with a 12-year history of old myocardial infarction and a 7-year history of type 2 diabetes mellitus was diagnosed with CC and underwent right hemicolectomy 1 year ago. Tumor biopsy revealed moderately poorly differentiated adenocarcinoma. Subsequently, chemotherapy with oxaliplatin and paclitaxel was administered. Anastomosis recurrence and pelvic metastasis were noted 37 d later. The patient received eight 21-d cycles of adjuvant chemotherapy with oxaliplatin and capecitabine after recurrence. However, the tumor persisted, and chemotherapy-related liver damage developed gradually. Thus, he was advised to take TCM for the recurrence and pelvic metastasis. The patient’s metastatic CC was cured after receiving TCM combined with long-term chemotherapy. CONCLUSION: TCM may be an effective adjunct therapy in the treatment of patients with metastatic CC.
