Abstract:
We report a case of advanced relapsed colon cancer, which had multiple liver and spleen metastasis, controlled for about two years by capecitabine therapy. A 60-year-old female had been diagnosed with ileus due to sigmoid colon cancer in August, 2005. She received sigmoidectomy and adjuvant chemotherapy (Leucovorin/5-fluorouracil therapy). In postoperative observation, multiple liver and spleen metastasis were detected by computed tomography in February, 2008. Therefore, she was administered twenty courses of FOLFOX therapy. However, a peripheral nerve disturbance appeared. There fore chemotherapy was changed from FOLFOX therapy to FOLFIRI therapy. After 2 courses of FOLFIRI therapy, she had severe nausea, vomiting, appetite loss and diarrhea. Therefore, chemotherapy was changed from FOLFIRI therapy to capecitabine therapy. After capecitabine therapy, her multiple liver and spleen metastasis disappeared, and complete response has continued for about 2 years. She has remained on capecitabine therapy and has a good quality of life.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
