Because of the wide variation in reported benefits from the use of intrahepatic chemotherapy for colorectal hepatic metastases, the authors performed their own phase II studies comparing the use of intrahepatic chemotherapy alone and intrahepatic chemotherapy as an adjuvant to complete or partial removal of metastatic colorectal cancer to the liver. Techniques for partial removal included unilateral and bilateral wedge resection, peripheral presinusoidal embolization of the liver, and portal vein branch ligation. Patients were staged using the per cent hepatic replacement method of Pettavel and Taylor, and patients with bilateral metastases were included in the study. Twenty-seven patients, mean age 60.3 years, were examined. There were 19 males, mean age 60.4 years, and eight females, mean age 60 years. The patients were divided into four groups. Group A had an implantable pump only; Group B had an implantable pump and resection; Group C had an implantable pump and arterial embolization and portal vein branch ligation; and Group D had an implantable pump, partial resection, arterial embolization, and portal vein branch ligation. Kaplan-Meyer survival curves were calculated for all of these groups. A separate analysis was carried out for each of the stages, and a comparison was made. The study indicated that the overall median survival time was 18 months and that the more radical the treatment in addition to chemotherapy, the better the results. Such results were not totally dependent on the staging of the tumor volume but were dependent on the degree of extirpation of the tumor. In Group C, consisting primarily of Stage IIa, IIIa, and IV patients (i.e., unresectable patients), a doubling of expected median survival to 12 months could be achieved, compared to those in Group A, which achieved a median survival of only 6 months.

Five patients with gestational trophoblastic disease whose presenting symptom was hemorrhage from vaginal metastases have been added to our previous report. The clinical features, management, and responses to treatment are outlined. All the patients required suturing of the bleeding lesions under general anesthetic to arrest the hemorrhage. In addition one patient needed selective arterial embolization. This did not compromise the response to chemotherapy. We confirm our previous view that the presence of vaginal metastases should be classified as a high-risk factor and that these patients be treated with multiple agent chemotherapy from the outset.

Transcatheter arterial embolization (TAE) is an effective means of treating primary hepatocellular carcinoma (HCC). However, in many cases of HCC the tumor recurs after treatment. In an attempt to obtain complete tumor necrosis, the authors studied the clinical and histologic effect of simultaneous embolization of both the hepatic artery and portal vein in ten patients with HCC. In those cases in which combined embolization caused infarction, tumor cells in the main tumor, tumor cells that had invaded the tumor capsule, and small intrahepatic metastases had become totally necrotic following treatment. No viable tumor cells were detected in four patients who subsequently underwent operations; nor were viable tumor cells present in one other patient who later died as a result of a perforated duodenal ulcer. Five patients who did not subsequently undergo operations were still free of the disease 2-17 months after combined arterial and portal embolization. The impact of combined embolization on liver function was nearly the same as that produced when TAE was performed alone. Combined embolization may be a viable alternative to hepatectomy for the treatment of HCC.

The patient, a 76-year-old woman, was found to have a tumor in the epigastrium in April 1983 and was admitted to our hospital. She was diagnosed as having hepatocellular carcinoma in the left lobe of the liver with intrahepatic metastases in the right lobe. The patient also had autoimmune hemolytic anemia. Because of this condition and the metastases, we decided that the tumor was not resectable. Transcatheter arterial embolization was unsuccessful, and therefore, beginning on June 28, 1983, the patient was treated three times using balloon-occluded arterial infusion of 10 mg of mitomycin C and 30 mg of adriamycin into the proper hepatic artery. After these treatments, the serum alpha-fetoprotein level returned to normal levels. CT scans and hepatic angiography showed that the main tumor and the metastases had become smaller. The patient presently shows no evidence of disease, three years after treatment.

A patient with metastatic islet cell carcinoma demonstrated multiple clinical syndromes simultaneously with secretion of ACTH, gastrin, glucagon, and serotonin. Hepatic arterial embolization resulted in an initial decrease in all secretory products, which was sustained for glucagon and serotonin. Recrudescence of the Cushings and Zollinger-Ellison syndrome was managed by surgical extirpation of the primary tumor and regional metastases as well as bilateral adrenalectomy. Electron microscopy and immunocytochemistry of the primary tumor and the metastatic lesions revealed the presence of multiple types of granules within single cells and, different patterns of secretory profiles in different tumor sites.

The number and site of brain metastases were identified on the computed tomographic scans of 288 patients. There was one brain metastasis in 49%, two in 21%, three in 13%, four in 6%, and five or more in 11% of scans. In patients with one metastasis, the posterior fossa was involved in 50% of patients when the primary tumor was pelvic (prostate or uterus) or gastrointestinal, but it was involved in only 10% of patients with other primary tumors. Hemispheral metastases preferred the anatomic "watershed areas" (29% of the brain surface contained 37% of the metastases), indicating that tumoral microemboli tend to lodge in the capillaries of the distal parts of the superficial arteries. The charts of 134 patients with brain metastases from a primary tumor originating outside the lung revealed that the incidence of lung and spine metastases was the same, whether the primary tumor was pelvic or gastrointestinal or from another site. These data suggest that the high incidence of subtentorial lesions in patients with pelvic and gastrointestinal primary tumors cannot be explained by arterial embolization alone, and that this peculiar distribution is probably not explained by seeding of the brain through Batson's plexus.

A combined treatment of alpha interferon (INF), 8 MHz radiofrequency (RF) hyperthermia using Thermotron-RF Model 8 and/or irradiation was performed on a patient with advanced renal cancer. The patient was a 52-year-old male, who had received arterial embolization with a gelatin sponge and 60 mg of adriamycin for the right renal tumor in January, 1985. He was referred to our clinic in April, 1985. Computed tomography showed a right renal tumor, 120 x 105 x 80 mm. Histological examination revealed clear cell carcinoma of the right kidney. The tumor was unresectable because of the huge tumor size, invasion into the right lobe of the liver, multiple pulmonary metastases and severe dysproteinemia. From the beginning of May, 1985, administration of 3 x 10(6) units interferon-alpha (INF) daily and radiofrequency (RF)hyperthermia for one hour twice a week were started. By June 11, 1985, 10 sessions of RF-hyperthermia were performed. Thereafter, hyperthermia for the renal tumor was maintained once a week until June, 1986. From the middle of June, 1985, a gradual improvement of dysproteinemia and appetite loss, and a decrease of the right renal tumor size as well as disappearance of febrile attacks were attained. In November, 1985, mediastinal lymph node swelling developed. A combined therapy of RF-hyperthermia twice a week and irradiation with 2.0 Gy daily 5 times a week was started. A total of 14 sessions of RF-hyperthermia and 30 Gy of irradiation were delivered until January, 1986. Intratumoral temperature of the renal tumor reached 44.0 degrees C during the heating.(ABSTRACT TRUNCATED AT 250 WORDS)

Renal cell carcinoma during pregnancy is extremely rare. This 30-year-old patient was first seen on Dec. 18, 1983 at the 7th week of her 2nd pregnancy. She had asymptomatic hematuria. Cystoscopy revealed normal findings and sonogram showed well defined echogenic mass in the upper pole of the right kidney. She was admitted to our hospital on account of gross hematuria and severe lumbago on Jan. 19, 1984. The pregnancy was stopped by artificial abortion. Renal angiography revealed a rich-vascularized tumor in the upper pole of the right kidney. Preoperatively, arterial embolization was done and nephrectomy was performed. Histological examination showed a well-differentiated adenocarcinoma. There was no involvement of the renal vein and no lymph-node metastases were found in the operation specimen. The post-operative course was uneventful. This rare case of renal cell carcinoma during pregnancy is herein reported along with some discussion.

The chemotherapeutic and ischemic effects of a fibrin clot containing mitomycin-C were observed on a model of primary hepatoma using VX-2 carcinoma inoculated in to the subcapsule of the liver of rabbits. The results of antitumor effect suppression of pulmonary and intrahepatic metastases and survival time using the fibrin clot containing mitomycin-C were better than with other treatments, namely a one-shot infusion of MMC or embolization with fibrin clot only. A synergistic antitumor effect was obtained using embolization with the fibrin clot incorporating mitomycin-C. Using direct subcapsular inoculation with a VX-2 carcinoma block a solitary hepatic tumor was obtained which was hypervascular and resembled human primary hepatoma. These results suggested that a fibrin clot containing an anticancer drug is safe a and effective modality for hepatic or other arterial embolization therapies.

Eighty two cases of renal cell carcinoma, treated at our Department between July, 1971 and May, 1984, are reviewed. The highest incidence of this disease was seen in the 5th decade and the average age of the patients was 58.8 years. Male patients predominated over the female patients, the ratio being 1.6: 1. According to Robson's classification, thirty eight cases were in stage I, five cases in stage II, nine cases in stage III and thirty cases in stage IV. The overall survival rate at one, three and five years was 77, 58 and 48%, respectively. The most common symptom was macroscopic hematuria, followed by asymptomatic, lumbago and palpable mass. The site of distant metastases was most frequently in the lung, followed by the bone, liver and lymph node. There were no remarkable differences in the prognosis of stage I patients, between the group treated with preoperative renal arterial embolization and non-treated group. No remarkable difference was seen between the survival rate of the stage IV patients treated by nephrectomy and these not treated by nephrectomy. Renal arterial embolization was an effective therapeutic measure for patients with non-resectable stage IV renal cell carcinoma (p = 0.0647, compared with non-treated group).
