Many epidemiological studies and laboratory experimentations have shown that dietary omega-6 fatty acids stimulate and omega-3 fatty acids suppress tumorigenesis. On the other hand, some reports presented that parenteral administrations of unsaturated free fatty acids such as oleic, linoleic and linolenic acids inhibited the growth of a transplantable syngeneic tumor in mice. In this report, I examined the effect of alpha-linolenic acid on the growth of 17 lines of human tumor transplanted in nude mice and on the metastasis of Vx-7 tumor transplanted in rabbits. When alpha-linolenic acid was emulsified with HCO-60 and subcutaneously injected in the peripheral region of the transplanted tumor, complete cure rates for MKN-1, MKN-28, NOC-S and PL-14 human tumors were 100, 57, 25 and 75% respectively at a dose of 250 mg/kg/day for four days once a day, although it was not effective on GCH-nu and SKG-III. Using other tumor lines, T/C ratios of the transplanted tumor weight on day 31 were 4% for Taneda, 34% for Lx-1, 47% for Li-7, 31% for Sk-14, 49% for Kuronuma and 16% for Sawayama. When alpha-linolenic acid was intermittently injected in the same manner on day 3, 13, 17 and 24, T/C ratios of tumor weight were 24% for ALL, 34% for Taneda, 23% for Lx-1, 50% for Li-7, 47% for Sk-14 and 54% for Kuronuma. Mammary tumor line (Mx-1) did not respond to administrations of alpha-linolenic acid. Rabbit Vx-7 tumor cells transplanted via lympho-duct were trapped in lymphonodi to metastasize to other organs. When alpha-linolenic acid mixed with Lipiodol was injected once via lympho-duct on day 8 after tumor transplantation at a dose of 250 mg/kg, the tumor growth was reduced in lymphonodi poplitei to 14%, and thus highly inhibited the metastasis of tumor cells to lung.

Hepatocellular carcinoma has as poor prognosis. Curative surgical treatment remains the first-line treatment. However, because of the limited indications and the high recurrence rate of this cancer, nonsurgical treatments have been developed. Intraarterial chemotherapy (with or without embolization or lipiodol), although effective on tumour bulk, has not yet been demonstrated to be effective on survival in the controlled studies published to date. Ultrasound-guided percutaneous alcohol injection, which is a more recent method, is simple, inexpensive and well tolerated. The inclusion of patients into controlled therapeutic protocols remains essential for both of these methods. Outside of the context of these studies, inoperable hepatocellular carcinoma without extrahepatic metastases can be treated by chemo-embolization in the case of unilobar tumours, without portal thrombosis, or major hepatocellular insufficiency or renal failure, and by alcohol injection in the case of small tumours, limited in number, without any serious clotting disorders or abundant ascites. When these two methods are contraindicated, endocrine therapy by tamoxifen remains an alternative to symptomatic treatment. In contrast, external beam radiotherapy, systemic chemotherapy and intraarterial chemotherapy without Lipiodol or embolization are no longer indicated. Finally, internal radiotherapy by intraarterial injection of lipiodol radioactive iodine is currently under evaluation.

Vascular invasion and intrahepatic metastasis by hepatocellular carcinoma are important factors predisposing to tumor recurrence. Recurrences of this malignancy occur frequently in residual liver, and its prevention is one of the most important factors in obtaining better surgical survival. Fifty patients who underwent hepatectomy for invasive hepatocellular carcinoma with vascular invasion and/or intrahepatic metastases were studied to evaluate the effect of adjuvant bolus hepatic arterial infusion of iodized poppyseed oil (Lipiodol) containing anticancer drugs in preventing recurrence and in prolonging survival. Patients were assigned to two treatment groups. Twenty-three of the fifty patients received adjuvant bolus infusion of Lipiodol containing doxorubicin and mitomycin C, whereas 27 patients received no therapy. The disease-free survival rate for the patients who received adjuvant therapy was significantly better (p < 0.05) than that for those who did not when measured at 172, 516, 688 and 860 days after hepatectomy, and the disease-free survival curve for patients with adjuvant therapy was significantly (p = 0.0237) better than that without adjuvant therapy. The cumulative survival rates and curves were not significantly different between the two groups. While adjuvant hepatic arterial infusion of Lipiodol containing anticancer drugs was effective in improving disease-free survival, the effect was not satisfactory. Further trials of adjuvant chemotherapy are required to improve the surgical survival of hepatocellular carcinoma patients.

A 68-year old woman underwent transarterial oily chemoembolization using Lipiodol with epirubicin hydrochloride and mitomycin C for treatment of multiple hypervascular hepatic metastases of gastric cancer. The tumors showed a good fixation of Lipiodol with a complete biologic response. The tumor has been well controlled for eight months by only one chemoembolization on follow-up study. Transcatheter oily chemoembolization may be an effective treatment not only for hepatocellular carcinoma, but also for hypervascular liver metastases from gastrointestinal malignancies.

The 5-year cumulative survival rate of 443 patients who underwent transcatheter chemoembolization (TCE) for non-resectable hepatocellular carcinoma (HCC) before December 1986 was 8.0%, and 29 patients survived for 5 years or more. Of these 29 patients, 25 were men and 4 were women; their mean age was 63.9 years. Macroscopic classification showed lesions of the single nodular type in 16 cases, the multiple nodular type in 10 cases, and the massive type in 3 cases; 12 of the single nodular lesions measured 5 cm or less in size. The TNM classification showed lesions of stage I in 3 cases, stage II in 14 cases, stage III in 6 cases, and stage IV in 6 cases. Lesions classified as Child A were found in 23 patients, and they were thus much more common than Child B lesions (2 patients) and Child C lesions (1 patient). The response was analyzed in relation to the use of iodized oil (Lipiodol). It was used in 215 of the patients, and the 5-year cumulative survival rate of those patients was 12.9% (23 of them survived for 5 years or more). Lipiodol was not used in 228 patients, and they showed a 5-year cumulative survival rate of 3.4%, with 6 patients surviving for 5 years or more. The 6 patients with stage III disease and the 6 with stage IV disease received Lipiodol. TCE with Lipiodol thus contributed greatly in prolonging the survival of patients with HCC complicated by intrahepatic metastases or intraportal tumor thrombi.

Lipiodol has previously been used as an agent for targeted radiotherapy by selective retention in primary hepatic tumours following direct hepatic arterial infusion. We have considered the potential dosimetry of 131I-labelled lipiodol in treating colorectal liver metastases. Fifteen patients with multiple colorectal liver metastases underwent selective hepatic angiography when 5 ml lipiodol labelled with 40 MBq 131I were infused. All patients underwent planar scintigraphy of the abdomen and thorax, single photon emission computed tomography (SPECT) of the liver and whole body counting on at least two occasions following lipiodol injection. Computed tomographic (CT) images of the liver were also taken typically 7 days postinjection. The lipiodol was found to deposit on the periphery of metastases of less than 10 cm diameter. In one patient a metastasis of diameter greater than 15 cm failed to infuse. In two patients the lobe of the liver containing metastases was not successfully infused. Overlay of CT and SPECT images confirmed concentration in metastases. Quantification of SPECT images indicated that between 55 and 100% (median 86%) of the injected activity was retained in the liver following injection, and tumour to liver ratios of dose delivered ranged from 1.21:1 to 4.7:1 (median 3.1:1). Tumour does ranged from 11.8 to 43.3 mGy MBq-1 injected. Dose to the lungs ranged from 0 to 46% of the liver dose (median 16%). Lipiodol has potential for treatment of colorectal liver metastases in targeted radiotherapy.

CDDP, 5-FU and LCV are administrated for recurrent gastric carcinoma in our hospital. We have been attempting translumbar local injection of a suspension of OK-432 and Lipiodol into the para-aortic lymph nodes or their surrounding areas for patients with para-aortic lymph node metastases when it was confirmed that the patient had a recurrence. This emulsion gradually degraded successively in the body. In this paper, we report the translumbar local injection method and its effective use in a case with para-aortic lymph node recurrence of gastric carcinoma.

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.

Colorectal malignancies metastasize most frequently to mesenteric lymph nodes. Preoperative staging of these nodes by current modalities is problematic. This study evaluates the feasibility of indirect mesenteric lymphangiography as a colonoscopic technique in a canine model. Ten mongrel dogs underwent endoscopic submucosal injection of Ethiodol at various sites in the transverse, descending, and rectosigmoid areas. Serial abdominal roentgenograms were obtained up to 2 weeks postinjection. In seven of the animals, demonstration of mesenteric nodal uptake corresponding to the area(s) of injection was radiographically documented. In the remaining animals (early in the series) nodal opacification was inadequate. This lack of nodal uptake appeared to be due to nonsubmucosal contrast injection. No complications were noted. Colonoscopic indirect lymphangiography appears to be a safe and potentially useful modality in the evaluation of mesocolonic lymph nodes. Further studies to refine this technique and investigate its potential to preoperatively delineate abnormal nodal architecture are warranted.

Primary and metastatic tumors of the liver can be treated successfully with transcatheter chemoembolization (TACE) during selective arterial catheterism. Arteritis is a possible referred side effect which can lead to tortuosity of the arteries, stenosis and occlusion of vessels. In our hospitals 117 consecutive patients were treated with TACE from January 1990 to December 1992; 61 patients were affected by hepatocellular carcinoma (HCC) and 56 were affected by metastases from colorectal carcinoma. Each patient received from 1 to 4 treatments at monthly intervals using epirubicin/Lipiodol ultrafluid (E/LUF) or a mixture of epirubicin and mitomicin C (MC)/LUF and followed by gelatine sponge injection in the hepatic artery. Selective angiography performed 30-62 days after the first chemoembolization showed artery stenosis in 7 patients and thrombosis in 2 cases related to toxic arteritis due to chemoembolization. Reports about arteritis during TACE treatments are discussed.
