[A Case of Radical Resection after CapeOX Therapy for Locally Advanced Sigmoid Colon Cancer with Anemia and Abscess Formation in a Jehovah's Witness].

The patient-a Jehovah's Witness-was a woman in her 60s, with locally advanced sigmoid colon cancer. She had severe anemia, and a computed tomography scan of her abdomen showed a tumor with abscess formation and perforation that had invaded into the left urinary duct and the left ovary, without distant metastasis. It was difficult to perform curative resections without transfusion; therefore, CapeOX therapy was plannedas the neoadjuvant treatment. After 3 courses of CapeOX therapy, the patient's anemia improved, and the tumor and abscess had shrunk. Subsequently, a sigmoidectomy with D3 lymph node dissection, partial resection of the small intestine, and the left adnexectomy, as a radical surgery, were performed without blood transfusion. In cases of concomitant colon cancer with anemia that are treated with highly invasive surgery, it might be necessary to conduct systematic treatment in order to complete non-transfusion therapy.
