Coincident with medical antitumor treatment of 138 patients suffering from mid-gut carcinoid tumors, 51 patients were subjected to surgery with the principal aims of removing primary tumors and debulking mesenteric or liver metastases. Sixteen patients had previously been operated with intestinal resection or, when the tumors had been considered inexcisable, with intestinal bypass or laparotomy alone. Apart from exhibiting symptoms related to the carcinoid syndrome, the majority (approximately 60%) of the 51 patients had generally intermittent, subileus-like abdominal pain and weight loss. In 18 patients, these symptoms were pronounced and associated with intestinal obstruction or severe malnutrition. Computed tomography and arteriography efficiently demonstrated mesenteric and liver metastases. At laparotomy, the primary intestinal tumors were small, mainly less than 1 cm in diameter, and they were multiple in 39% of the patients. Mesenteric metastases measuring up to 12 cm in diameter were present in 86% of the patients. These metastases were frequently associated with a pronounced mesenteric and retroperitoneal fibrosis causing fixation, angulation, and obstruction of the bowel as well as incipient intestinal gangrene in 8 patients. In all but 6 patients, the primary tumors could be removed by comparatively limited intestinal resections although bulky mesenteric metastases were often dissected from the mesenteric vessels. Liver metastases, found in 49% of the patients, were generally bilateral and multiple, and major hepatic metastases were resected in 6 patients. The results support a role for surgery also in the more compromised patients with mid-gut carcinoid tumors and that such intervention may be associated with considerable symptomatic relief and substantial periods of survival.

HCC occurs infrequently in Western countries, with recent increases being reported in California and parts of Europe. Southeast Asia, Japan, and South Africa continue to have a high incidence of this tumor with HBV, cirrhosis, and the ingestion of aflatoxins being identified as probable risk factors. Although the majority of patients present with abdominal pain or mass indicative of extensive tumor, asymptomatic, small HCCs are being detected with increasing frequency. Early detection in high-risk individuals is best accomplished by screening with serum AFP determinations and liver ultrasonography. CT and arteriography are valuable preoperatively in defining anatomy and determining resectability. Five-year survival following resection for cure of HCC ranges from 20 to 40 per cent, with improved survival reported for small asymptomatic tumors. Resection of metastatic liver tumors from colorectal primaries results in 48 per cent 2-year and 24 per cent 5-year survivals, with an additional 5 per cent dying of recurrent cancer after 5 years. Although patients with simultaneous and metachronous metastases do equally well after resection, the presence of four or more individual deposits adversely affects survival. Hepatic artery ligation or embolization can produce a significant palliative reduction in total tumor mass in patients with unresectable liver metastases. Regional chemotherapy using implantable hepatic artery drug infusion pumps is promising, with reports of prolonged survival compared with historical controls. Regional hyperthermia, laser vaporization of tumor, and cryosurgical techniques may prove to have useful roles in the selective treatment of liver cancer in the future. Orthotopic liver transplantation has been successful primarily in those in whom the malignancy is found incidentally in the chronically diseased liver.

Seven patients with progressive ileal or caecal carcinoid tumors and liver metastases were treated with human recombinant alpha-interferon (IFN alfa-2b) at a dosage of 2-4 x 10(6) U daily or every other day subcutaneously. Six patients had symptoms of the carcinoid syndrome. No change of tumor size lasting 4 to 40+ months (median, 18 months) was noted in 6 patients, and 1 patient had hepatic tumor progression. A decrease in urinary excretion of 5-hydroxyindoleacetic acid by more than 50% lasting 2-11 months (median, 4) was observed in 5 patients. Four patients were completely or partially relieved of flushing, diarrhea, obstruction or abdominal pain. The side-effects were negligible with the exception of mild fever, headache and confusion only during the first days of therapy. Treatment with IFN alfa-2b offers good palliation to patients with disseminated ileal or caecal carcinoid tumor and carcinoid syndrome.

Transcatheter chemoembolization using Degradable Starch Microspheres (DSM) was performed in 17 patients with liver metastases of colorectal cancer. Mitomycin C mixed with DSM was injected into the proper hepatic artery. Tumor regression of over 50% was observed in 9 of 17 cases (53%). Elevated serum CEA levels (greater than 10 ng/ml) decreased in 10 of 15 cases (67%). One-year survival rate was 50% in 17 cases. One-year survival rate was 100% in 7 cases with several liver metastases (H2). Abdominal pain occurred in 36%, mostly disappearing within 2 hours. No major side effects such as bone marrow suppression or hepatotoxicity were observed. Our results suggest that chemoembolization using DSM is effective and safe in the treatment of liver metastases from colorectal cancer.

Fifty-eight patients with colorectal liver metastases were treated by intra-arterial hepatic chemotherapy (IAHC) containing 5 FU (n = 42) or FUDR (n = 16). Twenty-three patients (39.6 p. 100) complained of abdominal pain. In three of these patients, the course was complicated by digestive hemorrhage. Endoscopic explorations and angioscintigraphy were normal in 4, showed oesophagitis in 3, superficial gastritis or duodenitis in 8 (34.7 p. 100) and gastric (2) or duodenal ulceration (6) in 8 (34.7 p. 100). The duodenal ulceration was extensive and considered to be cause of hemorrhage in two cases. Duodenal perforation due to the catheter was discovered in two other cases, one of which was secondary to tumoral extension revealed by forceps biopsy. This patient died 3 months later. Surgical treatment was mandatory in the other case due to digestive hemorrhage but did not prevent death. Angioscintigraphy performed in 15 patients with gastroduodenal inflammation or ulceration was normal in 7 patients, revealed arterial thrombosis in 5 and an extra-hepatic perfusion in the gastroduodenal area in 3 : this was related to a small pyloric artery which was occluded secondarily. IAHC was continued there after. This experience underlines the importance of exploring patients with digestive symptoms during IAHC so that it may be temporarily discontinued while an inadequately positioned infusion catheter may be corrected should gastroduodenal ulceration occur.

The authors reviewed the liver histopathology and the clinical features of eight patients with liver metastases from colorectal cancer who were treated by hepatic arterial infusion chemotherapy (HAIC) via an implantable pump (Infusaid). Before HAIC, these patients had no evidence of hepatitis, and results of liver biopsies performed on three patients showed only minor morphologic alterations. All the liver tumors responded to HAIC, but all patients developed hepatitis. Clinical findings included nausea, vomiting, abdominal pain and jaundice. Serum transaminases, alkaline phosphatase and bilirubin levels were increased. Clinical observations suggested that 5-fluoro-2'-deoxyuridine (FUDR), the predominant drug given, was the hepatotoxic agent. Toxic effects were hepatocyte necrosis, steatosis, cholestasis, central vein sclerosis, and alterations in the portal triad. In addition, central vein lesions like those in veno-occlusive disease, and micronodular cirrhosis resembling that induced by alcohol, were encountered. Although individual susceptibility to FUDR appeared to vary, portal triad fibrosis was present in all eight cases and, together with central vein sclerosis and cirrhosis, appeared to be related to the dose and duration of HAIC.

Twelve patients with small-cell lung cancer seen during a 30-month period had jaundice at diagnosis. Five patients had a pancreatic metastasis resulting in extrahepatic biliary obstruction, and seven had diffuse hepatic metastases without extrahepatic obstruction. All patients with pancreatic masses had complete (or nearly complete) resolution of jaundice and abdominal pain within 3 weeks of starting chemotherapy. Patients with extensive liver metastases usually remained icteric in spite of intensive treatment. Three patients with pancreatic metastases survived more than 12 months after the institution of therapy. No patient presenting with jaundice caused solely by hepatic metastases survived beyond 8 months. Small-cell lung cancer can present with jaundice due to diffuse hepatic parenchymal involvement, which is associated with a poor prognosis, or as a result of extrahepatic biliary obstruction, which has potential for rapid palliation and prolonged survival.

Veno-occlusive disease (VOD) of the liver was diagnosed in 8 patients with Wilms' tumour and peliosis hepatis (PH) in one. Fever of obscure origin, vague abdominal pain, hepatomegaly or hepatosplenomegaly, severe anaemia or sudden, unexplained drop in haemoglobin, thrombocytopenia, increasing serum transaminase levels, jaundice and ascites recorded within the first weeks or months of tumour diagnosis should arise suspicion of non-metastatic vascular hepatopathy. General or focal decreased accumulation of isotope at liver scintigraphy belong to the early radiologic findings. Sonography and CT may show a generalized irregular echogenicity or attenuation but no unequivocal metastases. One patient with PH had multiple low attenuating foci in both liver lobes and angiographically abnormal pooling of contrast medium in the liver. It is important to recognize these conditions as alternatives to suspected liver metastases, which as a rule develop much later yet on occasions may have very similar radiologic appearances. Therefore the relation in time between tumour diagnosis, initial operation and development of obscure hepatic manifestations is of critical significance for the recognition of VOD or PH. In these patients chemotherapy and irradiation must be discontinued without delay. If the disorders are adequately treated the prognosis may be considered fair.

Forty-nine patients with liver metastases of breast cancer were treated with arterial infusion involving simultaneous use of adriamycin: 30-50 mg and mitomycin C: 10-20 mg through the hepatic artery by Seldinger catheter. Of 45 evaluable patients, there were 5 complete and 12 partial responses (CR + PR: 38%), 21 no change and 7 cases of progressive disease. The median duration of response was 5 months. The median survival time was 7.5 months in all cases, 8.7 months for responders and 6.4 months for non-responders. Leukopenia less than 4 X 10(3)/mm3 was observed in 73% of cases, thrombocytopenia less than 100 X 10(3)/mm3 in 35%, and a decreased hemoglobin value of more than 2 g/dl in 4%, but these were well tolerated. Nausea (53%), vomiting (43%), fever (12%), abdominal pain (6%) and liver toxicity (2%) were observed, but these were manageable. We conclude that this arterial infusion therapy is a useful treatment modality for controlling liver metastases of breast cancer.

Between May 1980 and July 1983, the RTOG conducted a randomized prospective study comparing external radiation therapy and misonidazole to radiation therapy alone for patients with hepatic metastases. Two hundred fourteen patients were accessioned to this study of whom 187 were evaluable. Radiation therapy was delivered to the whole liver to a dose of 21.0 Gy in 7 fractions. Misonidazole was administered orally, 1.5 gm/m2 daily 4-6 hr before each treatment. Patients in the two treatment groups were evenly distributed with respect to stratification variables including primary site, extent of metastatic disease, and Karnofsky Performance Score (KPS). End points examined included amelioration of hepatic pain, improvement of KPS and alkaline phosphatase, decrease in liver and tumor size, and survival. The addition of misonidazole did not significantly improve the therapeutic response to radiation therapy in any of the parameters studied. Hepatic irradiation was effective in relieving abdominal pain with 80% of the symptomatic patients achieving improvement following therapy. Pain was completely relieved in 54% of these patients. Patients with liver metastases from colon carcinoma improved more frequently than those with metastases from other primary tumor sites (p = 0.02). Relief of pain occurred more frequently in patients treated with radiation therapy and misonidazole (87%) compared with radiation therapy alone (74%) (p = 0.08). Palliation of pain was prompt, occurring within a median of 1.7 weeks from the initiation of treatment, and 94% of patients who improved did so within 6 weeks of treatment. The median duration of response was 13.0 weeks in the symptomatic patients; 52% of those surviving 3 months remained improved. KPS improved in 28% of patients. Serial CT scans revealed a partial response in 7% and a marginal response in 13% of patients. One patient had a complete response to treatment. The median survival of patients treated in this series was 4.2 months with no difference between the two treatment groups. Patients with metastases from colon carcinoma and an initial KPS of 80 or more (48% of the patient population) had a median survival of 5.8 months with radiation therapy alone compared with 6.6 months with radiation therapy and misonidazole (p = 0.36). There was no significant treatment related morbidity. Radiation therapy remains an excellent palliative tool for the management of patients with symptomatic hepatic metastases. Further research must continue to identify new methods of selectivity enhancing the tumor response to radiation therapy.
