An 81-year-old woman, who suffered from ascending colon cancer with liver metastases, underwent right hemicolectomy. She did not undergo liver resection due to her age and her family's decision, and was treated with UFT plus oral Leucovorin therapy. The metastases were remarkably reduced in the early phase and disappeared completely on SPIO-MRI 2 years 9 months later. Adverse effects of this therapy are relatively few, and it can serve as first-line chemotherapy for advanced colorectal cancer.

The subject was a 75-year-old female. For the treatment of multiple liver metastases from sigmoid colon cancer, the administration of UFT(300 mg/day)and oral Leucovorin(75 mg/day)was initiated after a resection of the sigmoid colon. A decrease in the liver metastases was observed in a CT scan 4 months after the start of this administration, and the disappearance of the metastatic focus in the liver was confirmed at 10 months thereafter. The administration of UFT and oral Leucovorin was continued for 2 months. Thereafter, at 12 months after the start of this administration, was continued with only the administration of UFT(300 mg/day)for 1 year. Now, 26 months have passed since the liver metastases disappeared and no recurrence has been found, even within the abdominal cavity. The condition of the patient has been excellent. The subject of this study was an elderly person, but an excellent QOL was secured without any adverse events, and the chemotherapy regimen could be maintained for 2 years. These findings suggest that UFT and oral Leucovorin can be expected to have an excellent therapeutic effect as an oral chemotherapeutic agent.

We report three cases of complete response (CR) after treatment with UFT/LV for recurrent colorectal cancer. Case 1: A 44-year-old man was diagnosed with multiple liver metastases after resection of cecal cancer. UFT (500 mg/day)/Leucovorin (75 mg/day) was administered. Metastatic lesions of the liver completely disappeared on computed tomography(CT)one month after chemotherapy. Grade 2 hyperbilirubinemia and grade 1 diarrhea, pigmentation and rash were recognized. No signs of recurrence were observed for 35 months. Case 2: A 66-year-old man who underwent left colectomy and partial hepatectomy for transverse colon cancer and descending colon cancer with liver metastasis was determined to have multiple lung metastases. UFT/LV therapy was started. The lung lesions became only scars 7 months later. Adverse events were not seen. No other recurrence was found over 20 months. Case 3: A 66- year-old woman was detected with a lymph node recurrence after surgery for rectal cancer. CT revealed the disappearance of the tumor after 7 courses of UFT/LV therapy. Grade 2 hyperbilirubinemia appeared. Recurrence was not observed for 22 months, and the treatment has been discontinued.

Oral tegafur/uracil (UFT)/Leucovorin (LV) therapy has been used for chemotherapy for advanced colorectal cancer with anti-cancer effects the same as conventional 5-fluorouracil and Leucovorin (5-FU/LV). However, the effectiveness and safety of UFT/LV in the treatment of elderly patients with advanced colorectal cancer is not evaluated. We report a case of multiple lymph node metastases from colon cancer successfully treated with UFT/LV. An 81-year-old man had been admitted to our hospital because of left neck and axillary mass, which was diagnosed as transverse colon cancer with multiple lymph node metastases. After a laparoscopic partial resection of transverse colon, UFT/LV (UFT 300 mg/m2/day and LV 75 mg/day) was administered for 4-week-on and 1-week-off. After the administration of the chemotherapy, a good partial response of these metastatic lymph nodes was achieved. No grade 3 or more severe adverse reactions have been observed. He has now survived for 14 months without a recurrence after the administration of the chemotherapy. This case suggests the effectiveness and safety of UFT/LV in elderly patients with colorectal cancer.

Many patients with stage III colon cancer, and selected patients with stage II disease, will obtain significant benefit from adjuvant chemotherapy. Combination regimens that include a fluoropyrimidine plus oxaliplatin are the current standard of care, based on findings from the Multicenter International Study of Oxaliplatin/5-Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer (MOSAIC) and the National Surgical Adjuvant Breast and Bowel Project (NSABP) C-07 trials. Ongoing randomized trials are evaluating oral fluoropyrimidines combined with oxaliplatin and the addition of targeted therapies to oxaliplatin-based regimens for use in colon cancer adjuvant treatment. Adjuvant treatment approaches for patients with rectal cancer (stage II and III) now include preoperative chemoradiotherapy, based on a phase III comparison of preoperative vs. postoperative chemoradiotherapy conducted in Germany. Ongoing trials are evaluating new cytotoxic and target-oriented agents used in both the neoadjuvant and adjuvant settings in these patients. Improved surgical and radiotherapy techniques may also contribute to superior patient outcomes. Additional research is needed to identify patient subgroups at risk for recurrence, predictive factors for treatment response, and better treatment strategies for patients with colon and rectal cancer.

The patient was a 41-year-old female, who underwent histectomy and sdnexopexy due to perforated ovarian tumor. One month later, she was diagnosed with simultaneous bilateral metastatic ovarian tumor of colon cancer, and right hemicolectomy (D3) was performed. After surgery, the patient was treated with 10 courses of therapy with the FOLFOX4 regimen. No recurrence was recognized, and the patient was treated with 12 courses of therapy with oral tegafur/ uracil (UFT)+oral Leucovorin (LV). The patient evidenced no tumor recurrence 2 years after the initial treatment. We consider oral UFT+oral LV therapy was useful for post FOLFOX4 therapy after R0 surgery.

A69-year-old man was diagnosed with sigmoid colon cancer and underwent resection of the sigmoid colon. He was later diagnosed with multiple liver metastases 11 months after resection of the sigmoid colon cancer. He was treated by intraarterial chemoembolization using degradable starch microspheres (DSM) and radiofrequency ablation therapy. As a systemic therapy, combined oral administration of tegafur/uracil (UFT) and Leucovorin(Uzel) was started (UFT 450 mg/day, Leucovorin 75 mg/day, 4 weeks of therapy followed by a 1-week treatment break). Two months after 4 courses, the liver metastases had markedly diminished and CEA was within the normal range. The metastases had almost disappeared and tumor markers decreased to within normal limits. This treatment was very safe and effective. Such a strategic multidisciplinary treatment can lead to a better prognosis for colorectal cancer with liver metastases.

The patient was a 75-year-old man who was admitted because of diarrhea and anemia. Endoscopic examination revealed advanced sigmoid colon cancer. Serum CEA levels were markedly elevated. In July 2007, surgery was performed, but the sigmoid colon cancer was unresectable. After surgery, the patient was treated with chemotherapy and concurrent radiotherapy. The chemotherapy consisted of oral UFT (420 mg/body/day)and Leucovorin (75 mg/body/day) administered for 6 weeks. Radiotherapy at 2 Gy/day was administered 30 times (total dose 60 Gy). The tumor decreased slightly in size and serum CEA levels also decreased. The patient refused surgery as an additional therapy. In August 2007, we started combination chemotherapy using oral S-1 (100 mg/body/day, day 1-14) and intravenous CPT-11 (140 mg/body/day, day 1 and 15) as one course for 4 weeks. After 4 courses, serum CEA levels were normal, the sigmoid colon cancer was not found by endoscopy and a biopsy specimen revealed no malignant cells. Moreover, after 8 courses, the tumor disappeared, as confirmed by computed tomography (CT) and positron emission tomography-CT, representing a complete response. Chemoradiotherapy using UFT and Leucovorin, and chemotherapy consisting of S-1 and CPT-11 as an additional therapy may be effective for treating unresectable advanced sigmoid colon cancer.

Leucovorin is a reduced form of folic acid, which has multiple uses.(1) In this case report, it is used in combination with fluorouracil in the treatment of colon cancer. We describe a 53-year-old male, who was started on FOLFOX 6 + bevacizumab who experienced a hypersensitivity reaction to leucovorin. There have been very few cases of leucovorin hypersensitivity reactions reported in the literature. In this case, symptoms include flushing, hives, body pain, headaches, elevated blood pressures, and general discomfort. Although leucovorin reactions are considered rare, one should be aware of the types of reactions that can occur with leucovorin.

The efficacy of oxaliplatin monotherapy against several solid tumors and its relative lack of nephrotoxicity and myelosupression, coupled with results of the Multicenter International Study of Oxaliplatin/5-Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer trial, led to a great deal of interest for the implementation of this chemotherapeutic agent in the preoperative setting for the management of adenocarcinoma of the rectum. Despite limited in-vitro and in-vivo data with regard to the radiosensitizing properties of oxaliplatin in rectal cancer, it rapidly entered phase I-III clinical trials. This study reviews the results of these trials and the current status of oxaliplatin as a radiosensitizing agent in the neoadjuvant management of rectal cancer.
