[Basic and clinical studies on metastatic cancer--with special reference of multidisciplinary treatment of gastric and colorectal cancer patients with hepatic metastasis].

We studied 161 gastric cancer patients with P0, H(+) and 51 colorectal cancer patients with P0, H(+) from among cancer patients of the digestive organs and obtained the following conclusions. The effective treatment for synchronous hepatic metastasis was regarded as the group with surgical removal of the primary lesion plus hepatic resection plus chemotherapy, demonstrating most favorable prognosis in both gastric and colorectal cancer patients. Prognosis of the group treated with surgical removal of the primary lesion plus hepatic resection plus chemotherapy, was the most excellent and was followed by the group with surgical removal of the primary lesion plus chemotherapy and group with surgical removal of the primary lesions and group surgical removal of the primary lesion in this order. Concerning chemotherapy after surgical removal of the primary lesion, continuous intraarterial infusion therapy with FML regimen combining Lentinan revealed more favorable prognosis also in both gastric and colorectal cancer patients. Hepatic resection with aggressive reduction surgery was of significance in the treatment for the patients with hepatic metastasis of H1 and H2. Long-term survival is also expected for the patients with metachronous hepatic metastasis of H1 by hepatic resection plus chemotherapy.

[Evaluation of the therapeutic effect of HCFU (1-hexylcarbamoyl-5-fluorouracil) on non-resectable stomach cancer].

The present study was aimed at investigating the efficacy of a new oral anticancer agent, HCFU, that is, (1-hexylcarbamoyl-5-fluorouracil), against 14 cases of unresectable gastric cancers which were confirmed by the laparotomy. The daily dose was 600mg and given continuously as long as the patients could take the drug orally. The efficacy was examined by X-ray photographs according to the criteria for the judgement of direct effect of the chemotherapy for solid malignant tumor. For the diffuse invasive type of gastric cancer, the changes in the X-ray finding such as stiffness and poor elasticity of gastric wall and malignant relief were also taken into consideration for the judgement. Among 9 patients, in whom the efficacy was measurable, two cases showed "partial response (PR)", two cases were diagnosed as "no change (NC)" and other 5 cases were diagnosed as "progressive disease (PD)". Among 2 partial responders, 1 case showed 85.3% decrease of the tumor size on the X-ray film and the other, who had diffuse invasive gastric cancer, showed much improvement on the X-ray film described above. The survival was around 5 months in "progressive disease" group. On the other hand, the patients with the good response to HCFU such as PR patients and NC patients could obtain a relatively longer survival period.

Sonographic appearances of small hepatic nodules without tumor stain on contrast-enhanced computed tomography and angiography.

PURPOSE: We report the sonographic appearances and pathologic findings for hepatic nodules 2 cm or smaller that were detected by sonography but that did not produce a tumor stain on constrast-enhanced helical CT or digital subtraction angiography. METHODS: Sixty-six nodules 2 cm or less were found by sonography in 39 patients. Sonographically guided needle biopsies were done on all lesions. RESULTS: Twenty-seven nodules were benign nodules, 9 were borderline lesions, and 30 were hepatocellular carcinomas. Benign nodules were significantly smaller than hepatocellular carcinomas (mean size, 1.0 cm versus 1.4 cm, respectively; p <0.00001). Nodules 1 cm or smaller were more likely to be diagnosed as benign nodules (68%) than as either of the other types (32%; p = 0.01). A significantly greater percentage of hepatocellular carcinomas showed a heterogeneous pattern (64%) on sonography compared with benign nodules (25%) and borderline lesions (11%; p = 0.04). In nodules 1 cm or smaller, a homogeneous pattern (68%) was more common than a heterogeneous pattern (32%; p = 0.01). CONCLUSIONS: The nature of small hepatic nodules cannot be determined with sonography. Thus, biopsy remains the only technique for obtaining a definitive diagnosis.
