We report a patient with multiple hepatic metastases from colorectal cancer effectively treated by hepatic arterial infusion therapy (5-FU/LV therapy). The patient was a 55-year-old man with sigmoid colon cancer and multiple hepatic metastases, 5 cm in diameter, in both lobes of the liver. First, we locally controlled the sigmoid colon cancer by sigmoid colectomy (with D3 lymph node dissection). After resection of the primary cancer lesions and dissection of the lymph nodes, we treated the patient by systemically administering 4 courses of Leucovorin/5-FU (once weekly for 6 weeks per course) from a port-catheter system during hospital stay and in the outpatient clinic after hospital discharge. Assessment of therapeutic effects by CT showed CR in the patient. CEA levels, which were abnormal before and after surgery, decreased to normal at the end of chemotherapy. After 1 year, neither CT evidence of tumor enlargement in the liver nor re-increase in CEA levels has been noted. Although the patient experienced side effects such as pigmentation, grade 1 loss of appetite, and leukopenia, he was able to maintain his QOL in the absence of severe side effects.

Oxaliplatin is available in numerous countries for the treatment of metastatic colorectal cancer (in conjunction with fluoropyrimidine therapy). The activity of oxaliplatin in advanced disease has led to investigation of its potential in operable disease. The addition of oxaliplatin to adjuvant therapy with fluorouracil and folinic acid (FOLFOX4 regimen) is associated with a significantly greater disease-free survival at 3 years (78% vs 73%; p = 0.002), according to results of the MOSAIC (Multicenter International Study of Oxaliplatin/5FU/Leucovorin [folinic acid] in the Adjuvant Treatment of Colon Cancer) trial, a study in 2246 patients with stage II or III colon cancer. In addition, a 23% reduction in the risk of disease recurrence after surgery was seen with FOLFOX4 compared with fluorouracil/folinic acid in the MOSAIC trial. Results from several phase I/II studies suggest that the addition of oxaliplatin to preoperative radiochemotherapy may be of benefit in patients with locally advanced lower rectal cancer in terms of disease downstaging and sphincter preservation. Oxaliplatin was generally well tolerated in the MOSAIC trial and neuro- and myelotoxicity with FOLFOX4 were manageable.

We considered the appropriateness of RFA, which was performed in three cases of colorectal cancer with hepatic metastases accompanied by liver cirrhosis. Case 1 involved a patient with sigmoid colon cancer ss, n1 (+) with severe hepatic dysfunction and synchronous hepatic metastases (S5, S6, S8) in which RFA was performed. After 1 year and 6 months, recurrence (S3, S4) was detected in the residual liver, and the patient is currently undergoing the IFL (CPT-11/5-FU/Leucovorin) treatment. In case 2, following a partial hepatic resection, RFA was performed for cecal cancer ss, n2(+) with synchronous hepatic metastases (S5, S6, S8). After 11 months, recurrence (S5, S6, S7) occurred in residual liver and again RFA was performed following a partial hepatic resection. Lung metastases have occurred and currently IFL (CPT-11/5-FU/Leucovorin) and WHF treatments are underway. In case 3, 4 years and 8 months after cancer of the descending colon ss, n1 (+), RFA was performed on asynchronous hepatic metastases (S5, S7, S8). The patient died of peritonitis carcinomatosa one year after RFA. In all three cases, metastases were identified by dynamic CT as low density masses with no blood flow. Necrosis in all three metastases and local control had been achieved. There were no severe complications. Under the current conditions, local coagulation methods including RFA are appropriate in those cases in which resection are not possible such as multiple metastases with severe hepatic dysfunction, etc.

We report the complete response for one year of a patient with simultaneous multiple lung metastases from colon cancer who was treated using a combination of irinotecan (CPT-11) and uracil/tegafur (UFT)/Leucovorin (LV) using a schedule reported overseas. A 61-year-old woman was admitted to our hospital and diagnosed with ascending colon cancer and simultaneous multiple lung metastases. The patient underwent a right hemicolectomy and was treated with CPT-11 (150 mg/m(2)) on day 1 and oral UFT and oral LV on days 1-14. This treatment cycle was repeated every 3 weeks. A CT examination after 4 cycles of chemotherapy revealed a partial response of multiple lung metastases, and the next examination after 6 cycles revealed a complete response. The adverse effects observed during this chemotherapy regimen were leucopenia (grade 1), neutropenia (grade 2), vomiting (grade 2) and hair loss (grade 1). The patient is now receiving her 22nd cycle of chemotherapy, and her multiple metastases have shown a complete response for one year. The CPT-11 and UFT/LV combination therapy was well tolerated and was covered by the national health insurance system in Japan. This treatment may enable prolonged survival and improve quality of life in patients with metastatic colorectal cancer.

An 81-year-old man was admitted to our department due to acute ileus. He was diagnosed with sigmoid colon cancer with multiple metastatic lesions in the right lobe of the liver. Two weeks after insertion of an ileus tube, he underwent sigmoidectomy and permanent colostomy. The final diagnosis was stage IV sigmoid colon cancer with metastasis to the omentum. One month after the operation, adjuvant chemotherapy with oral administration of tegafur/uracil compound (UFT) and Leucovorin (LV), and drip venous infusion of irinotecan hydrochloride (CPT-11) was initiated (UFT 300 mg/day for 14 days, LV 75 mg/day for 14 days, CPT-11 90 mg/m(2) on the 1 st day, with 1 course consisting of 21 days). The levels of tumor markers, CA19-9 and CEA, and the size of metastases on CT were reduced remarkably after one and 4 courses of this therapy, respectively. Although the administration was temporarily discontinued due to low-grade nausea, we continued the treatment. Adjuvant chemotherapy with an oral administering agent is favorable for older patients with advanced colorectal cancer to reduce side effects and preserve the quality of life.

The patient was a 63-year-old man,who first visited our hospital with the chief complaints of left lower quadrant pain and abdominal distension that had developed around November 13, 2004. On close examination, he was diagnosed with sigmoid colon cancer, multiple liver metastasis, and subileus due to a lung metastasis. His operation took place on December 12 of the same year. Intraoperatively, the sigmoid colon was firmly fixed to the retroperitonium, there was a hard node in the pouch of Douglas, and that part of the jejunum was involved. The lesion was judged to be unresectable,and thus loop colostomy, partial jejunectomy and gastrojejunostomy were performed. After the surgery,the patient was treated with 4 courses of therapy with oral Leucovorin (LV, 75 mg) +oral tegafur/uracil (UFT, 400 mg). As a result, the tumor marker levels decreased markedly, the lung metastasis was no longer observed and the liver metastases became smaller. Therefore, a second-look operation was performed on May 30, 2005. This time it was relatively easy to free the sigmoid colon. The node in the pouch of Douglas was no longer observed, and there were only 2 metastatic lesions in the liver (1 each in S 2 and S 6). Sigmoidectomy and partial hepatectomy were performed, and the stoma was closed. The patient made good progress after the operation and was discharged on the 11 th POD. At present he is receiving chemotherapy with UFT+oral LV as an outpatient. As this therapy is relatively easy to perform and imposes only a small burden on patients,we think that it may be effective not only as adjuvant chemotherapy but also as neoadjuvant chemotherapy in some patients.

In patients with colon cancer who undergo resection for potential cure, 40% to 60% have advanced locoregional disease and are classified as either stage II or stage III. The role of adjuvant therapy in stage III colon cancer is well defined. The results from the MOSAIC trial (Multicenter International Study of Oxaliplatin/5-Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer) and the National Surgical Adjuvant Breast and Bowel Project C-07 trial confirm a definite disease-free survival (DFS) benefit with the addition of oxaliplatin to either infusional or bolus 5-fluorouracil/leucovorin (5-FU/LV). The Xeloda in Adjuvant Colon Cancer Therapy (X-ACT) trial showed capecitabine to be of equivalent clinical benefit to bolus 5-FU/LV. However, adjuvant trials with irinotecan, including Cancer and Leukemia Group B (CALGB 89803), the Pan-European Trial in Adjuvant Colorectal Cancer 3 (PETACC-3), and the French ACCORD trial, have not shown a significant DFS advantage. In contrast, in patients with stage II disease, a small survival benefit of 1% to 5% exists with chemotherapy. Perhaps the analysis of molecular markers in combination with high-risk histopathologic features will help increase patient specificity and identify subsets of patients with stage II colon cancer who will derive a survival benefit with adjuvant therapy. The current Intergroup study stratifying stage II patients based on presence of microsatellite instability and loss of heterozygosity 18q allele will help us better understand the risk versus benefit observed.

A 72-year-old woman, who had the carcinoma of cecum with unresectable multiple liver metastases, underwent ileocecal resection and insertion of hepatic arterial infusion catheter. Hepatic arterial infusion (HAI) chemotherapy using Leucovorin. 5-FU caused to decrease liver metastases after an initiation of HAI. However, the metastatic nodule at the right lobe of lung was found. Then systemic chemotherapy with CPT-11 CDDP was performed alternately with HAI chemotherapy. After the initiation of revised regimen, all metastatic lesions were shrunk. We here in present the case of extra- and intra-hepatic metastasis successfully treated with alternative chemotherapy with hepatic arterial infusion and systemic intravenous infusion after responding to hepatic metastasis from colon cancer by hepatic arterial infusion.

We report two cases of recurrent colorectal cancer in two patients who were treated successfully with a combined oral chemotherapeutic agent folinate/tegafur/uracil (UFT/LV) dosage. The first case was a 74-year-old woman who underwent Hartmann operation for colon cancer perforation. One year and 7 months after surgery, a local recurrence was found on the CT scan and endoscopy. It ended in exploratory laparotomy though we were operated on. Chemotherapy using 5-fluorouracil/Leucovorin (5-FU/LV) was performed six times. Sequentially, UFT/LV internal use was managed at our outpatient clinic. This patient has been living without side effects in the first three postoperative years, and without increase in tumors. The second case was a 65-year-old woman who underwent abdominoperineal resection of the rectum for rectal cancer. The histologic stage of disease aggravation of the patient was stageI. Post operatively, 2 years and 6 months later, we recognized a metastasis node on the lung upper right lobe of the patient and her CA19-9 value climbed dramatically. The patient took UFT/LV during outpatient visits to the hospital, the lung node shadow disappeared two months later, and CA19-9 decreased, too. The patient is living without a cancer recurrence now. UFT/LV treatment is one of the effective modalities against recurrence of colorectal cancer from outpatient treatment while maintaining QOL.

A 78-year-old male with sigmoid colon cancer underwent sigmoidectomy. The lesion was se, p1(+), n1, and Stage IV. Oral UFT therapy was performed, but was replaced with oral S-1 therapy 1 year and 6 months after surgery. Three months later, lung metastases 2.0 x 1.5 cm and 0.6 x 0.6 cm were found by chest CT in right S10a and S5b, respectively. Since the patient did not wish surgery, the treatment was changed to oral UFT/Leucovorin(LV)therapy(UFT 300 mg/ LV 75 mg, 4-week administration and 1-week no-administration periods). After 2 courses, chest CT showed disappearance of both lung metastases, indicating complete remission. Oral UFT/LV therapy is convenient because of the oral route. Adverse reactions are few, and the therapeutic effect has been reported to be comparable to that of intravenous 5-FU/LV therapy. Also, in this patient, no adverse reaction was noted, and complete remission was maintained until the patient died of another disease 31 months after the beginning of oral UFT/LV therapy.
