Chemoembolization using Lipiodol, cisplatin, angiotensin II and Gelfoam (modified sandwich therapy) was carried out for the patients with liver metastasis from colorectal cancer. 1. Ten of 30 patients who underwent hepatic resection received TAE before operation, and the remaining 20 underwent surgery without preoperative TAE. Three-year survival of the former was 66%, and that of the latter was 44% (not significant). 2. Twenty-two patients who were assessed as non-resectable were surgically catheterized into the hepatic artery. Thirteen patients received TAE (totally 38 times) and intra-arterial infusion chemotherapy, and the remaining 9 underwent intra-arterial chemotherapy alone. The 50% survival of the former and the latter was 545 and 285 days, respectively. One year survival of the former was significantly better than that of the latter. 3. Fourteen patients had intrahepatic recurrences after hepatic resections. Eight patients received TAE and the remaining 6 did not. The 50% survival of the former was 615 days and that of the latter was 190 days. For one-year survival, the former was significantly better than the latter. These results suggested that TAE is an effective modality for liver metastasis from colorectal cancer.

A total of 45 metastases to the liver from colorectal cancer were resected in 22 patients. The detectability of these lesions with the following modalities was determined: real-time ultrasound (US), computed tomography (CT), selective celiac arteriography (SCA), infusion hepatic angiography (IHA), CT during arterial portography (CTAP), and CT following intraarterial injection of iodized poppyseed oil (Lipiodol). The total detection rate (sensitivity) was 58% for US, 63% for CT, 27% for SCA, 50% for IHA, 84% for CTAP, and 38% for CT with iodized oil. Ten of 18 lesions less than 15 mm in largest diameter were demonstrated preoperatively by CTAP only. CTAP is useful in clarifying the locations of the lesions in the liver and should always be performed before liver metastases from colorectal cancer are resected.

A new method of arterially administering an oily anticancer agent was successfully established for the selective targeting of metastatic lymph nodes. A high molecular weight anticancer agent, a conjugate of copolymer (styrene maleic acid) to neocarzinostatin (SMANCS) was prepared in our laboratory and dissolved in a lymphographic oily contrast medium, Lipiodol (SMANCS/Lipiodol). SMANCS/Lipiodol was administered intraoperatively to eight patients with colorectal cancer and preoperatively to one patient with gastric cancer with lymph node metastases. In six of the patients with colorectal cancer, the drug was administered via an artery and in the other two patients the drug was injected into the wall of the colon near the primary cancer. In the patient with gastric cancer, the drug was administered via the left gastric artery. Delivery of the drug to the lymph nodes was examined roentgenologically and the anticancer effect was examined histologically. The results showed that SMANCS/Lipiodol could be delivered to the metastatic lymph node via the artery, but it could not be delivered to the metastatic lesion of the lymph node via the lymphatic route. In the patient with gastric cancer, SMANCS/Lipiodol preoperatively administered via an artery was found to remain selectively in a metastatic lymph node and an anticancer effect was histologically proved in all three of the metastatic lymph nodes.

Major hepatic resection is the treatment of choice in patients with primary and secondary liver cancer. During a 22-month period 31 men and 27 women (mean age 63 years, range 14-84) with space-occupying hepatic lesions were admitted. All 15 patients with benign lesions were operated, except for 3 in whom a liver abscess was drained percutaneously. Of the 43 with malignant liver lesions, 30 had liver metastasis secondary to colorectal cancer, 15 of whom underwent major, anatomical and nonanatomical, liver resection and 1 had cryoablation of the tumor. 9 had hepatocellular carcinoma, 1 of whom had a 4-segment non-anatomical resection and 1 tumor cryoablation. 2 with metastasis from a neuroendocrine tumor had anatomical resection of liver lobes. Of 2 with liver metastasis secondary to breast cancer, 1 underwent resection. CT portography, intraoperative ultrasonography and intraarterial injection of Lipiodol were found to be very useful in selecting patients for liver resection.

Postoperative adjuvant locoregional chemotherapy was performed on patients who underwent hepatic resection for metastatic colorectal cancer. To prevent recurrence in the residual liver after hepatic resection. 7 patients received intra-hepato-arterial infusion of MMC, 5-fluorouracil (5-FU), doxorubicin + Lipiodol emulsion. Sixteen cases did not receive such treatment. The 1-, 2- and 3-year cumulative disease free rates were 100, 80 and 40% in the patients with this adjuvant chemotherapy, against 61.4, 54.6 and 28.1% in those without this locoregional therapy, respectively. The 1-, 2- and 3-year cumulative survival rates were 100, 100 and 60% in the TAI-E group, and 73.7, 63.3 and 63.3% in the patients without TAI-E, respectively. Postoperative adjuvant locoregional chemotherapy is considered effective to prevent the recurrence of metastatic colorectal cancer in the residual liver after hepatectomy.

Response of transcatheter arterial chemoembolization (TAE) and transcatheter arterial infusion chemotherapy to hepatic metastases was reported in 25 cases of colorectal cancer. The severity of liver metastases was H1 in 12 cases, H2 in 9 cases, and H3 in 4 cases. Liver metastases were found during surgery in 12 of these patients, and 13 showed metastases or recurrence in the liver after resections of primary lesions. Catheters were inserted selectively to the proper hepatic artery by Seldinger's method, followed by injection of embolizing agents (gelfoam particles of Lipiodol) with adriamycin or 5-FU + leucovorin in most cases. Response was assessed by blood CEA levels, diagnostic imaging, and period of survival. In 5 cases in whom liver resections were performed following TAE, response was assessed by histopathological findings of the resected specimens. Two patients showed partial response (PR), 12 no change (NC) and 11 progressive disease (PD) by diagnostic imaging. Blood CEA levels fell to less than 50% of pre-treatment levels in 26% of cases. Histological changes by TAE were confirmed in 4 of 5 cases after liver resections, but viable cancer cells were observed in all cases. A case of mucinous cancer showed no change histologically. As the other case of mucinous cancer showed PD by diagnostic imaging, TAE was not suggested to be suitable to treat cases of mucinous cancer. More improvements in the dosage, drugs and times of treatment were suggested to yield a better response rate in TAE therapy for liver metastases from colorectal cancer.

To compare the prognostic benefit between arterial embolization chemotherapy (AEC) and continuous arterial infusion chemotherapy (CAIC), we clinicopathologically examined 32 colorectal cancer patients with liver metastases. Seventy patients were treated with AEC, and 15 patients with CAIC. In the AEC regimen, either ADR or CDDP dissolved in Lipiodol was infused by the implanted reservoir every one to two months. Otherwise, for the CAIC regimen, 360 mg/m2/day of 5-FU was continuously infused by the reservoir for 14 days. Subsequently, on day 22 after the initial 5-FU infusion, 180 mg/m2/day of 5-FU was continuously infused for 7 days. After a 7-day interval without infusion, 180 mg/m2/day of 5-FU was infused for 7 days. This 7-day infusion/7-day no-infusion cycle was repeated. The efficacy of the AEC was 6% (1 PR + 7 NC + 9 PD), CAIC (6 PR + 4 NC + 5 PD), suggesting that CAIC provides the better response rate. With regard to prognosis, the 1- and 2-year survival rates of AEC were 63% and 19%, respectively. The median survival time was 415 days. Otherwise, the 1- and 2-year survival with CAIC was 54% and 40%, respectively, and the median survival time was 470 days. No significant difference between the AEC and the CAIC was observed in the colorectal cancer patients with liver metastases.

Results from clinical trials do not allow definitive conclusions about the role of chemoembolization (ChE) in the treatment of colorectal cancer (CRC) liver metastases. The aim of present phase II study was to investigate toxicity and efficacy of ChE for patients, with unresectable colorectal liver metastases after failure of 5-FU based chemotherapy. Secondary endpoint was clinical benefit measurement. Eleven patients were enrolled in first stage (two-stage Simon design), 2 males/9 females, median age 60 (46-71). Performance status was I in 8 patients and II in 3 patients. All patients had radical surgery, 7 of them adjuvant chemotherapy and 4 systemic chemotherapy. The ChE regimen consisted of an injection of iodinated oil Lipiodol with mitomycin C (3 mg/ml). Repeated treatments were performed at 9- to 12-week intervals. We applied 17 ChE (median 1/pts.). Clinical benefit was a composite of measurements of pain, ECOG performance status, weight and tumor fever. Study was stopped after first stage because non of the patients (pts) achieved objective response (RECIST). Stable disease occurred in 5 pts (45%). Median time to progression was 3 months (range 3-9 months). Median survival was 9 months (range 4-16 months). A decrease of the baseline carcinoembryonic antigen level occurred in 0% of the cases. Clinical benefit was recorded in one patient. Common toxicity included a "postembolization syndrome," which consisted of fever, pain in the right upper quadrant, nausea, and vomiting. Grades 3-4 toxicity (NCI-CTC) followed transaminases 6/11, LDH 4/11. In addition, a drop in F V levels was noted in 5 pts, F VII in 9, F IX in 2 and F X in 10 pts. Decrease in At III levels occurred in 6 pts and FDP appeared in one. Thus, The ChE as performed in the present study did not appear to bring any benefit; furthermore, significant liver toxicity compromises the safety of such procedure.

Although alpha-fetoprotein (AFP)-producing colorectal cancer is extremely rare, its potential for liver metastasis is high and the prognosis of the patient is very poor. We report a case of metastatic liver tumor from an AFP producing sigmoid colon cancer that was successfully treated with transcatheter arterial chemo-embolization (TACE). A 48-year-old female was admitted to our hospital complaining of anal bleeding, and was diagnosed as harboring a type 2 advanced tumor with two metastatic lesions in the lateral segment of the liver. Serum AFP measured 948.2 ng/ml before surgery. We performed sigmoidectomy and lateral segmentectomy of the liver. Pathological examination revealed moderately differentiated adenocarcinoma both in the primary and the metastatic lesions, and AFP-stain positive nests were seen on immunohistochemical staining. The serum AFP value returned to normal soon after the surgery. Five months later, a recurrent lesion was discovered in the right lobe of liver, and it was surgically removed. Another 4 months later, multiple liver metastases were recognized and the patient's serum AFP level was found to be 593.3 ng/ml. For the re-recurrent hepatic lesions of 5.5 cm in diameter, she underwent two courses of TACE using Lipiodol and epirubicin hydrochloride. Following the treatment, the tumor shrank rapidly and almost disappeared. The patient has been in good health for 24 months since the last TACE, and the serum AFP level has been within the normal range.

We report a case of inguinal lymphorrhea cured by Lipiodol lymphangiography. The patient was a 80-year-old female who underwent an abdomino-perineal resection with lateral pelvic lymph node dissection and inguinal lymph node extraction for anal canal cancer. Histologically, the tumor was a poorly differentiated adenocarcinoma and considered to be stage IV (a2, n3 (+), P0, H3, M (-), cur C) in the Japanese classification of colorectal cancer. We recognized a lot of lymph node metastases in dissected lateral pelvic lymph node and inguinal lymph node. By hepatic arterial infusion using 5-FU (1250 mg/body weekly), the liver metastases had a complete response after 15 courses. She noticed a left inguinal lymph node swelling and an elevation of serum CEA level (79.5 ng/mL) was observed. There was no evidence of recurrence except left inguinal lymph nodes. She underwent a left inguinal lymph node dissection. Serous discharge from a surgical site persisted despite of conservative therapy such as compression. She received lymphangiography using 8 mL of Lipiodol from left dorsum of foot. We found three lymph ducts heading to left groin and observed a lot of Lipiodol leakage from ducts. We determined not only the site of leakage but we also confirmed a gradual decrease and a complete stop of lypmphorrhea in 7 days after lymphangiography. Slight lymph edema of left lower extremity appeared but gradually relieved. Lymphangiography using Lipiodol helps determine the site of leakage and may be an effective therapeutic modality for treating refractory lymphorrhea.
