Combined chemotherapy consisting of oral TS-1 and low-dose CPT-11 by hepatic arterial infusion is suggested to be a new effective treatment for multiple liver metastases from colorectal cancer. A 53-year-old man was diagnosed with multiple hepatic metastases from advanced colon cancer (Stage IV). The patient underwent partial resection of the colon and catheter insertion into hepatic artery for arterial infusion in November 2003. He was treated with postoperative combination chemotherapy consisting of UFT and low-dose CPT-11. UFT was administered orally at 400 mg/body/day everyday and CPT-11 was injected at 40 mg/body/week for 6 weeks, followed by a 2 weeks rest interval as 1 cycle. In spite of the reduction of metastatic liver tumors after 2 cycles of the chemotherapy, a metastatic pleural tumor appeared. Therefore, we judged the effect of the chemotherapy to be a progressive disease and changed UFT in the regimen to TS-1. TS-1 was administered orally at 80 mg/body/day under a 2-weeks-on and 1-week-off regimen for 3 times. CPT-11 was injected at 40 mg/body/week for 6 weeks, followed by a 3 weeks rest interval as 1 cycle. A stable disease was maintained for 3 months. Outpatient care was possible because no severe events were observed. Tumors showed a reduction rate of 37.4% after the combination therapy. The patient survived for 285 days after the operation.

A 77-year-old woman underwent an ileocecal resection and a partial resection of the small intestine for cecal cancer. However, ileus caused by a recurrence in the small intestine was detected two years and four months postoperatively, so an ileal resection was performed. Furthermore, metastases to the lungs, lymph nodes, and peritoneum were detected, and CPT-11-based chemotherapy was administered. The patient was initially treated by combination therapy with a small dose of CPT-11 and CDDP. The combination drugs were changed to MMC, 5'-DFUR, etc. while the appearance of adverse reactions was monitored. Three years of continuous treatment served to prevent the proliferation of tumors. At present, TS-1 chemotherapy is ongoing. The results suggest that CPT-11-based chemotherapy can be continued by changing the combination of concomitant drugs while monitoring adverse reactions. It thus may be an effective regimen for advanced and recurrent large bowel cancer.

The transcription factor NF-kappaB is reportedly activated by anti-cancer chemotherapeutic compounds in many cancer cell lines and NF-kappaB activation is one mechanism by which tumors become resistant to apoptosis. Antioxidants have been reported to serve as potent NF-kB inhibitors. In this study, we investigated the ability of edaravone to enhance apoptosis induced by CPT-11 through inhibition of NF-kB. In vitro, SN38, the active metabolite of CPT-11, induced activation of NF-kB, the production of intracellular reactive oxygen species, the activation of caspase-3, and apoptosis in colon26 cells. Pretreatment with edaravone scavenged the SN38-produced reactive oxygen species, and inhibited the SN38-induced activation of NF-kB. Moreover, edaravone enhanced the activation of caspase-3, and the level of apoptosis induced by SN38. In vivo, the combination of edaravone with CPT-11 reduced subcutaneous tumor growth and number of pulmonary metastases more effectively than CPT-11 alone. These results demonstrate that the combination of edaravone with CPT-11 may constitute a new strategy for treating primary and metastatic colon cancer.

We successfully treated four advanced colorectal cancers with irinotecan (CPT-11) plus 5-fluorouracil (5-FU) and l-leucovorin (l-LV) combination chemotherapy. We diagnosed moderately-differentiated adenocarcinoma of the colon in two patients and of the rectum in two patients. We recognized lymph node metastases in one patient and liver metastases in three patients at the time of operation. After excision for a lesion of the colon or the rectum, all patients underwent a 2-week chemotherapy regimen (CPT-11 100 mg/m2/week + 5-FU 500 mg/m2/week + l-LV 10 mg/m2/week). The effect was PR in all patients. The progressive free survival time was 9.5 months and survival time ranged 5-18 months. Grade 3 diarrhea and leukopenia were seen in one patient. All other adverse reactions were mild (grade 1 or 2). CPT-11/5-FU/l-LV combination chemotherapy appears to be effective for advanced and metastatic colorectal cancer.

We have recently reported that low tumor levels of SMAD4, a key mediator of transforming growth factor-beta superfamily signaling, can predict the probability of recurrence in patients with Dukes C colorectal cancer who had surgery as the only form of treatment. However, standard treatment for Dukes C colorectal cancer patients currently involves the administration of 5-fluorouracil (5-FU)-based adjuvant chemotherapy after surgery. Approximately 30% to 40% of these patients present with recurrence and die within 5 years, and there is great need for markers capable of predicting poor prognosis after the combined surgery/adjuvant treatment. In this study, we evaluate the prognostic value of SMAD4 in patients treated with surgery and 5-FU-based adjuvant therapy. We used immunohistochemistry and quantitative real-time reverse transcription-PCR to measure the levels of SMAD4 protein and mRNA expression in the primary tumors and a number of lymph node metastases from a series of 75 Dukes C colorectal cancer patients with at least 6 years of follow-up. Patients with tumors expressing low levels of SMAD4 protein or mRNA showed significantly shorted disease-free and overall survival than patients with high tumor levels of SMAD4. The median survival of patients with low SMAD4 protein or mRNA tumor levels was 1.4 and 1.2 years, respectively, whereas patients with high SMAD4 tumor level had a median survival of >9.3 years. In addition, the protein and mRNA levels of SMAD4 in lymph node metastases was significantly lower than in primary tumors (P = 0.006). In contrast, allelic imbalance in chromosome 18q21 was of no prognostic significance in these patients. In conclusion, low SMAD4 tumor levels identified a subset of patients with poor prognosis following surgery and 5-FU-based adjuvant therapy; therefore, these patients could be good candidates to receive combined treatment with additional chemotherapeutic agents such as CPT-11 and/or oxaliplatin.

TS-1/CPT-11 combination therapy was carried out in a case of advanced gastric cancer with liver and lymph node metastases and obstructive jaundice after percutaneous transhepatic cholangio drainage (PTCD). Regression of the primary carcinoma and reduction in size of metastases were observed. Grade 1 fatigue and grade 2 neutropenia were noted as adverse reactions to the treatment. TS-1/CPT-11 combination therapy was useful in this case of advanced gastric cancer with liver and lymph node metastases.

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.

A 50-year-old woman visited our hospital with a chief complaint of lower abdominal mass. The patient was diagnosed with rectal cancer using colonoscopy and also diagnosed with unresectable rectal cancer because abdominal CT revealed metastases to the liver, lung and lymph node located porta hepatis. The patient was treated with TS-1 combined with CPT-11. The TS-1 (80 mg/m2) was orally administered for 2 weeks and followed by a 2 week interval, and CPT-11 (80 mg/m2) was simultaneously administered biweekly. One cycle of chemotherapy was 28 days. The patient experienced grade 1 leukocytopenia and neutropenia. Abdominal CT revealed partial response after 2 cycles. After 6 cycles, the patient was subjected to curative operation. Pathological efficacy was Grade 1a at lymph node metastasis and Grade 3 at liver metastasis. TS-1 combined with CPT-11 regimen was very feasible and convenient, and obtained a good compliance. So this regimen was promising for unresectable colorectal cancer. In the future, this regimen will be verified in phase III clinical trial and compared with FOLFIRI and FOLFOX regimens.

We report a case in which 5-HT3 receptor antagonist, indisetron hydrochloride,was effective against CPT-11-induced diarrhea. When the patient, a 63-year-old male, developed lymph node metastases after resection for primary gastric cancer, 24-hour continuous administration of CPT-11 (125 mg/m2) was initiated. The following day he had diarrhea, possibly associated with the CPT-11. Hange-shashinto was administered but did not improve the condition. Thereafter, the diarrhea followed a protracted course (grade 1 to 2). His diarrhea improved when indisetron hydrochloride was administered with the fifth course of chemotherapy in place of the usual antiemetic drug. In this patient, indisetron hydrochloride, in addition to its role as an antiemetic, was considered to be effective against CPT-11-induced diarrhea.

Patients with bilobar colorectal cancer metastases to the liver present a unique problem in terms of resection. They sometimes require a staged approach to resection that takes advantage of the liver's ability to regenerate, as well as the newer chemotherapeutic agents (e.g., oxaloplatin, irinotecan (CPT-11), and bevacizumab) that have become available. In cases of multiple bilobar metastases, if segment IV is clear of tumor, a left lateral segmentectomy (LLS) can be performed, followed several months later by a formal right hepatectomy. The remnant liver composed of the hypertrophied segment IV is drained by the middle hepatic vein (MHV). In this context, patients with lesions between the origin of the MHV and the inferior vena cava (IVC) present a particularly difficult problem. Conventional excision would require an extended hepatectomy and division of the MHV along with either the right or left hepatic veins (RHV, LHV). This would make it impossible to continue with a formal resection of the remaining lesions in the contralateral liver without sacrificing the sole remaining hepatic vein. We present a novel two-step hepatectomy for lesions between the MHV and the IVC that allows the MHV to be preserved and all lesions to be resected.
