Fifty-seven patients with non-resectable liver metastases (31 from colon cancer, 26 from gastric cancer) received 5-FU, ADR, MMC combined hepatic arterial infusion therapy. (FAMia: 5-FU 334 mg/m2 qw, ADR 20 mg/m2 q4w, MMC 2.7 mg/m2 q2w; in colon cancer, 5-FU 167 mg/m2/day continuously for 3 months and then 334 mg/m2 qw). Myelo-suppression, hepatic arterial occlusion, gastroduodenal toxicity and elevation of biliary enzyme were observed at 29%, 39%, 32% and 13% in colon cancer, respectively, and at 35%, 8%, 0% and 0% in gastric cancer, respectively. Response rates evaluated by CT-scan were 63% (1 CR + 18 PR/30) in colon cancer and 79% (4 CR + 15 PR/24) in gastric cancer. Overall median survival was 352 days in colon cancer and 449 days in gastric cancer. Concerning background factors, the response rate in the well-differentiated type of colon cancer was significantly higher than in the moderately differentiated type, and significantly low in poorly differentiated medullary type gastric cancer. The existence of extra-hepatic lesions was the most important factor in survival in both cancers. [colon cancer: (-) 740 days vs (+) 267 days; gastric cancer: (-) 517 days vs (+) 245 days]. In conclusion, this therapy yields favorable direct effects on liver metastases from colon and gastric cancer without major side-effects and complications, but effective therapy of extrahepatic lesions is required for longer survival. Now, to release colon cancer patients from restrictions of continuous infusion pumps, a phase I study of weekly high dose 5-FU HAI therapy is under way.

This study evaluates tumor response, survival, and development of resistance to HAI chemotherapy, comparing a combination of bolus MMC and short duration FUdR to short duration FUdR alone or to long duration FUdR alone, using a rat hepatic metastases model. After intrasplenic injection of 10(7) K12/TRb colon cancer cells in BD-IX rats on day 0, hepatic metastases were evaluated and HA catheters were placed on day 14. The response was determined on day 28. Chemosensitivity of the hepatic metastases after HAI treatments was determined using the MTT assay. Bolus MMC with short duration FUdR as well as long-term FUdR alone provided better hepatic tumor response and survival than short-term FUdR alone. However, bolus MMC with short duration FUdR decreased the acquired resistance to FUdR, compared to long-term FUdR, without causing resistance to MMC. These results provide a rationale for using short duration of FUdR in combination with other drugs.

A weekly HAI therapy (CPT-11 80 mg, MMC 4 mg, degradable starch microsphere (DSM) 600 mg) was given to a patient with sigmoid colon cancer and multiple liver metastasis (H3) who had been taking tegafur 300 mg/day and 5-FU 750 mg HAI/week, which resulted in PD. This therapy was carried out on an outpatient basis with minimum side effects (< grade 2). After 8 weeks, the tumor marker dropped to one tenth and the liver metastasis decreased in size (PR). The time courses of the concentrations of CPT-11, SN-38 and SN-38G were determined by drawing blood after HAI with or without DSM. The Cmax and AUC inf. of SN-38 at HAI without DSM were 17 ng/ml and 90.55 ng/h/ml, respectively, which was comparable to that at i.v. administration. The Cmax and AUC inf. of SN-38 at HAI with DSM were 12 ng/ml and 129.19 ng/h/ml, respectively, implying that DSM might have an enhancing effect on CPT-11 due to stasis of the hepatic artery that slows the conversion of CPT-11 to SN-38 resulting in a longer existence of SN-38.

A 54-year-old woman who had ascending colon cancer with multiple liver and lung metastases underwent rt. hemicolectomy and catheter insertion into the gastroduodenal artery for arterial infusion chemotherapy. On postoperative day 7, she had nausea and vomiting due to the enlarged multiple liver metastases on lateral segment. Intraarterial infusion of 5-FU 1,000 mg/m(2) for 5 hours weekly (WHF: weekly high-dose 5-FU) was started at first. After 3 courses, her symptoms improved, oral intake could be started, and liver metastases showed significant reduction on abdominal CT. Three months after surgery, bone scinti revealed multiple bone metastases. Combined HAI (5-FU: 600 mg/m(2)/3 hr) chemotherapy with UFT (400 mg/body) + CPT-11(80/body) and UFT (400 mg/body)/LV (75 mg/body) + CPT-11(100 mg/body) were effective for highly advanced colon cancer in terms of QOL. Eight months after surgery, she was doing well and the chemotherapy was continued. WHF therapy was effective for digestive symptoms due to liver metastasis.

The prognosis of a colorectal cancer patient with unresectable hepatic metastases is extremely poor. To improve the prognosis, when the hepatic metastases were initially unresectable, we performed second-look hepatectomy (s-l hepatectomy) after neoadjuvant hepatic arterial 5-FU infusion plus UFT (HAI-PMC). Here, we report the case of a sigmoid colon cancer patient with initially unresectable hepatic metastases showing a prolonged survival (6.5 years) by second-look operation after HAI-PMC. A 57-year-old woman was diagnosed with sigmoid colon cancer with unresectable liver metastases. Sigmoidectomy and hepatic arterial catheterization were performed in the initial operation, and HAI-PMC was performed 6 months after. Metastatic foci of the liver had shrunk (90.9%), but solitary metastatic lung cancer was detected during HAI. As no other metastatic lesion was observed, partial resection of the liver and lung was performed as a second-look operation, 6 months after the initial operation. The woman continued venous infusion chemotherapy as an outpatient, and she survived for 6.5 years after the initial operation. This result suggests that strategic multidisciplinary treatment utilizing s-l hepatectomy after neoadjuvant chemotherapy can lead to better prognosis for colorectal cancer patients with hepatic metastases.

In May 2005, a 79-year-old woman was referred to our hospital with complaints of right lower quadrant mass and feces mixed with blood. After examination, she was diagnosed with ascending colon cancer and synchronous multiple liver metastases. Postoperative diagnosis after right hemicolectomy and D3 lymph node dissection was T2, N1, H2, P0, M0, and Stage IV. One month after the operation, we started a combination chemotherapy using 5-FU plus UFT as pharmacokinetic modulating chemotherapy with hepatic arterial infusion (HAI-PMC). But abdominal CT scan revealed the increase of multiple liver metastases, PD, after 4 courses of treatment. We then changed to modified HAI-PMC (additional CPT-11, once every four weeks), but had to cancel it due to her exhaustion and inappetence. Therefore, S-1 was started from October, 2005. Each course consisted of daily oral administration of 80 mg S-1 for 4 weeks and withdrawal for 2 weeks. After 4 courses, abdominal CT scan revealed a reduction in the number of multiple liver metastases, PR. PR has continued for a long term to date. As an adverse event, we had grade 3 neutropenia and grade 2 diarrhea in January 2009, and we changed the administration method (80 mg S-1 for 2 weeks and withdrawal for 1 week). She continues to undergo outpatient treatment with good QOL without a lesion for 4 years and 6 months. S-1 is expected to be an effective agent for the treatment of advanced colon cancer.

We report a case of patient who recovered from liver failure with synchronous diffuse liver metastases of sigmoid colon cancer by a short-term high volume (6 g of 5-FU in a week) hepatic arterial infusion (STHV-HAI). After four times of STHV-HAI, she had sigmoidectomy and bilateral oohorectomy and continued a weekly hepatic arterial infusion therapy until now. The case was a 75-year-old lady. She admitted of general fatigue. Serum bilirubin was about 2 mg/dL, GOT about 200 U/L and CEA over 40 thousand ng/mL. She started STHV-HAI next day of her admission. After 4-course, her liver function became normal and the amount of CEA level became about 1,000 ng/mL. We had the operation of sigmoidectomy and bilateral oohorectomy. After that, she received the HAI every week as an outpatient. The lowest level of CEA became at the 90 ng/mL. The liver metastases were also almost CR. STHV-HAI will be safe and effective to a patient of liver metastases with ascites and jaundice.

We report a patient who experienced a weight loss, general fatigue, and appetite loss and had huge hepatic metastases of colon cancer after right lobectomy for hepatic stone. After 2 courses of treatment with high-dose hepatic arterial infusion of 5-FU (HDHAI; 5-FU 6 g/week), the appetite loss decreased, and low anterior resection was performed. Unfortunately, the other symptoms continued, and she received 5 additional courses of HDHAI during about 6 months. Finally, all of the symptoms disappeared, and she could receive systemic chemotherapy and HAI. Bone metastasis at vertebra TH 9 was observed about 9 months after radiotherapy, and local recurrence at the anastomosis site was observed at about 1 year 1 months after radiotherapy. Both the metastasis and local recurrence were well controlled. Although the lung metastases were growing slowly (number and size), the patient was well enough to go to the hospital on her own and her weight loss almost disappeared. If liver metastases were the most threatening factor of life, HDHAI may be effective for the improvement of symptoms.
