[A long-term surviving patient with unresectable lung metastasis from colon cancer treated with intravenous administration of activated autologous lymphocytes and low-dose chemotherapy--a case report].

We herein report a case of long-term surviving patient who was treated with intravenous administration of activated autologous lymphocytes and low-dose chemotherapy. The patient was an 82-year-old female. She underwent radical resection for sigmoid colon cancer in 1998 and right lobectomy of the liver for metastatic liver tumor in 2001. A follow up CT revealed the metastasis to the bilateral lung on November 2003. Then she received a treatment with UFT plus low-dose CPT-11/CDDP and activated autologous lymphocytes. Although the response of the treatment was SD, the serum CEA level decreased to a normal range. The treatment continued with delayed administration for 30 months while CEA and the size of the tumors increased very slowly. After that, her treatment was changed with a single administration of S-1. She obtained a 3.5 year survival with an inhibition of fast tumor growth by chemo-immunotherapy.
