New development of transarterial immunoembolization (TIE) for therapy of hepatocellular carcinoma with intrahepatic metastases.

The prognosis of patients with multiple hepatocellular carcinoma (HCC) remains disappointing. In this study, we devised a new therapeutic modality for HCC consisting of transarterial immunoembolization (TIE) using OK-432 and fibrinogen and then analyzed the preliminary results. In the first series, we applied the treatment to 19 patients with advanced HCC who had proved to be insensitive to several previous conventional treatments. In all, 14 patients (74%) with unresected HCC have currently survived for between 2 and 16 months after TIE. The remaining 5 patients died at 17, 14, 8, 7, and 4 months after TIE. The serum levels of tumor markers decreased in all of the patients, and a marked reduction in tumor size was observed in six patients after TIE. A high fever occurred in all cases, and abdominal pain and loss of appetite were also observed after TIE. However, deterioration of liver function was negligible. After confirmation of the safety of this method, we started a second study series in which this TIE treatment was selected as the first choice. Six patients have been treated to date. All patients in this group underwent hepatic resection at 6-48 days following TIE. Histological examination of the resected specimens following TIE showed massive infiltration of mononuclear cells around tumor cell nests and lytic necrosis as well as coagulation necrosis of the main tumor and the intrahepatic metastases. In conclusion, our results indicate that TIE may be a safe and promising therapy for patients with HCC.

[Adoptive immunotherapy in patients with multiple hepatic cancers using lymphokine activated killer cells (LAK) and interleukin-2].

Tumor infiltrating lymphocytes (TIL) and peripheral blood lymphocytes (PBL) were isolated from 5 patients with multiple hepatocellular carcinoma (HCC) and with metastatic liver tumor. Proliferation of lymphocytes was observed following addition of interleukin-2 (700 JRU/ml) into the culture media. After analysis of LAK cells by FACS, the antitumor activities were examined. Higher levels of cytotoxic activity against tumor cells (K 562 and Daudi) have continued during the culture period ranging from 2 to 5 weeks. Adoptive immunotherapy was performed using TIL-LAK and PBL-LAK via hepatic artery for three patients with HCC and one patient with metastatic tumor. The average number of administered lymphocytes was 1 x 10(9). Reduction of tumor size was observed after this therapy, which caused no severe side effects exclusive of high fever and pleural effusion. Our results indicate that the treatment using lymphokine activated killer cells and interleukin-2 may be a promising modality for patients with multiple HCC.

[Efficacy of transarterial immuno-embolization therapy (TIE) in operable patients with hepatocellular carcinoma].

The efficacy of transarterial immuno-embolization therapy (TIE) was examined in six operable patients with hepatocellular carcinoma (HCC). We administered OK-432, fibrinogen (30 mg/ml) and thrombin (1 U/ml) through a catheter which was inserted into the tumor-feeding artery. In all patients with a high level of tumor markers (AFP and PIVKA-II), the level decreased promptly to less than the pretreatment level after TIE therapy. The therapy has not caused any serious side effects. No disturbance of the coagulation-fibrinolysis system due to TIE was observed in any patient. Histological examination of resected specimens following TIE showed massive infiltration of mononuclear cells around tumor cell nests, and lytic necrosis as well as coagulation necrosis of the main tumor and the intrahepatic metastases. Our results indicate that TIE may be an effective and promising modality for HCC patients.

[Studies on combination therapy with TAE and percutaneous ethanol injection therapy for unresectable hepatocellular carcinoma].

We studied and analysed the effects of combination therapy with TAE and PEIT for unresectable HCC. The subjects were 28 patients (21 males, 7 females) with 31 tumors treated in the Department of Surgery, Osaka Teishin Hospital. The patients were divided into four groups on the basis of the tumor size (< 3 cm, 3-5 cm, 5-8 cm, > 8 cm). The therapeutic effect on the tumors was evaluated on the basis of the maximum reduction rate within 3 months after TAE and PEIT. The response rates after treatment were 87.5%, 60.0%, 25.0% and 0% for < 3 cm, 3-5 cm, 5-8 cm, and > 8 cm tumor size, respectively. The 50% survival period was 50.9 months. The 1-, 2-, 3- and 5-year survival rates were 92%, 76%, 52% and 32%, respectively. In the cases of over 8 cm, this combination therapy had no effects on the survival period. The findings of the present study suggest that the combination therapy was useful for the unresectable HCC of under 5 cm in diameter.

Multiple colorectal carcinomas and colorectal carcinoma associated with extracolonic malignancies.

In this study, we analyzed 149 surgical cases of colorectal cancer between January 1983 and August 1989. Thirteen cases (8.7 percent) of colorectal primary cancer associated with extracolonic primary malignancy of 14 lesions and 10 cases (6.7 percent) of multiple primary colorectal cancers were included. Among the 14 lesions of extracolonic primary malignancy, there were 6 gastric carcinomas, 2 endometrial carcinomas, 2 urinary bladder carcinomas, and one each in the esophagus, liver, bile duct and jejunum. The second tumor was not detected preoperatively in 3 of 4 cases of synchronous multiple primary colorectal carcinoma. A curative resection was done in 10 (77 percent) out of 13 cases of colorectal cancer associated with extracolonic malignancy, while 7 (88 percent) out of 8 cases of multiple colorectal cancers had a curative resection. Nine patients (69 percent) with colorectal cancer associated with extracolonic malignancy were disease-free for 2 months to 14 years. Seven patients (88 percent) with multiple colorectal cancers were disease-free for one to 22 years. We recommend, therefore, that in any patient with colorectal cancer, the entire large bowel should be thoroughly searched for any other primary tumors, by taking the existence of extracolonic tumors into account. A curative resection should be performed, and the follow-up period should be life-long.

Efficacy of combination treatment--(TAE with adriamycin and ethanol)--for hepatocellular carcinoma.

Among 44 patients with hepatocellular carcinoma (HCC), combination treatment with both transhepatic arterial embolization (TAE) and ethanol injection therapy (EIT) was performed in 10 patients. Only two had tumors measuring less than 3 cm in diameter. In all, eight patients had solitary tumors and two had multiple tumors. The tumor was classified as stage I in one patient, stage II in six subjects, stage III in two patients, and stage IV in one subject prior to TAE, but one stage II case was changed to stage III after laparotomy. The clinical stage was I in two patients, II in six subjects and III in two patients. Five patients with tumors of stages I and II achieved either a complete response (CR) or partial response (PR). However, three patients with tumors of stages III and IV showed progressive disease (PD). Thus, the response rate (CR+PR) was 50%. For tumor stages I and II, the 1-, 2-, and 3-year survival values were 100%, 100%, and 83%, respectively. For tumor stages III and IV, the 1- and 2-year survival values were 75% and 25%, respectively. Combination treatment of HCC appears to be efficacious for tumor stages I and II.

[Combination of transarterial chemoembolization and endocrine therapy for liver metastases of breast cancer].

Nine patients with multiple metastases including liver from breast cancer were treated with transarterial chemoembolization through hepatic artery using 40-50 mg of 4'-epi-adriamycin and Lipiodol, followed by 800-1,200 mg/day of medroxyprogesterone acetate. Of 9 patients thus treated, there were 4 partial response (44%), 2 no change and 3 progressive disease. Duration of disease control ranged from 4 to 46 months (mean 24.5 months). Seven out of 9 patients died within 6 to 37 months (mean 15.3 months) after diagnosis of liver metastases. The 3- and 5-year survival rates were 45% and 11%, respectively. We conclude that this therapy is a useful treatment modality for controlling liver metastases of breast cancer.

Leiomyoma of the duodenum--a case report.

A 36-year-old man with anemia due to gastrointestinal bleeding, diagnosed to have a leiomyoma of the duodenum, is described. The conventional barium meal study and gastroendoscopy were useful for diagnosing the lesion. More invasive radiological methods, such as abdominal angiography and technetium-99m scintigraphy failed to detect the tumor. Early diagnosis and resection of the tumor would result in a good prognosis.
