Japanese men in Hawaii whose ancestral roots were in Okinawa were compared to Japanese migrants from all other prefectures. The Okinawan migrants have acquired fewer cancers than men from other prefectures (P = 0.12). No one primary site accounts for this difference. Stomach cancer rates showed the largest difference between the two migrant groups. This replicates the experience of Okinawans and non-Okinawans in Japan itself. Lymphosarcoma mortality rates are much higher in Okinawa than in all Japan, but this difference is not reproduced in Hawaiian migrants. This could be explained by a post migrational decrease in HTLV-I-related acute T-cell lymphoma/leukemia. Cancer of the mouth, pharynx and esophagus has decreased in all Japanese migrants, but the decrease is much greater among Okinawan migrants, suggesting they have escaped exposure to risk factors peculiar to the Okinawan environment. Colon cancer is more common in migrant Japanese than in U.S. whites. The dramatic increase in the frequency of this tumor affects Okinawan and non-Okinawan migrants to an equal degree.

Phosphotyrosine-containing proteins in various human cancer cell lines were studied by immunoblotting with anti-phosphotyrosine antibody. Of 29 cell lines derived from oral epidermoid cancer, esophageal cancer, gastric cancer, colon cancer, pancreatic cancer, hepatocellular carcinoma and malignant melanoma, 3 of the 6 gastric cancer cells showed aberrant elevation of tyrosine-specific phosphorylation. On the other hand, both esophageal cancer cells and colon cancer cells, which were reported to have amplified epidermal growth factor receptor and activated p60v-src kinase, respectively, showed no apparent elevation of tyrosine-specific phosphorylation, and their profiles of phosphorylation were similar to that of normal human fibroblasts. Two gastric cancer cells, NUGC-4 and MKN-45, showed similar profiles of phosphorylation but their responses to growth factors differed from each other. Tyrosine phosphorylation in NUGC-4 was strongly activated by treatment with epidermal growth factor and quickly reduced by the acid treatment which is effective in removing growth factors from cellular surface receptors. On the contrary, phosphorylation in MKN-45 did not respond to either growth factor or acid treatment. These results suggest that NUGC-4 and MKN-45 have tyrosine kinases which are activated by different mechanisms but share similar substrates.

Tumor-associated trypsin inhibitor (TATI) was assayed in serum of patients with gastroenterological diseases. Of the patients 92 had gastric cancer, 50 colonic cancer, 38 colitis, 36 polyposis of the colon, and 40 gastric ulcer. The cut-off level established on the basis of the mean concentration +3 SD of a reference population comprising 120 subjects was 32 micrograms/l. In gastric cancer TATI had a sensitivity and specificity similar to that of CA19-9, whereas its behavior in colon cancer was less satisfactory. Like other tumor markers TATI may be elevated in patients with inflammatory diseases. In our opinion TATI is a good tumor marker for gastric cancer and it is a useful complement to CEA and CA19-9.

Cancer mortality in the 35-74 year age-range for selected sites during the period 1979-88 was investigated for the 26 district council areas of Northern Ireland. Trends in rates during the period were also studied and compared with trends in an earlier period, and with trends reported from the rest of the United Kingdom. Statistically significant differences between the age-standardised death rates in the 26 areas were observed for stomach cancer (women only), pancreatic cancer (women only), lung cancer (men and women) and for all cancers (men and women). Some evidence of spatial aggregation of rates was apparent for ovarian cancer even though rates in the 26 areas did not differ significantly. The patterns are illustrated with maps and some difficulties of interpretation are discussed. Mortality rates for oesophageal cancer increased during the period in both sexes while rates for stomach cancer decreased. Colon cancer rates increased significantly only in men, while an increase in lung cancer rates was confined to women. The mortality from all cancers increased significantly during the period by 0.8% per annum in men and 0.9% per annum in women. These trends were found to be broadly comparable with those reported elsewhere in the United Kingdom.

An early phase II multicentered study of YM 881 (zinostatin stimalamer) was conducted in 36 patients to investigate response and the safety of the drug in malignant tumors. The response could be evaluated in 18 patients, one with brain tumor, 2 with lung cancer, one with breast cancer, one with liver cancer, one with pancreatic cancer, 6 with gastric cancer, and 6 with colon cancer. PR was found in the patient with brain tumor. Major subjective unwanted effects were gastrointestinal symptoms. Objective evidence of hematological changes (thrombocytopenia, decreased hematocrit, and lymphocytopenia) was also obtained.

We studied the effects of liposome-entrapped adriamycin (L-ADM) administered via the portal vein and the clinical application of this treatment in the therapy and inhibition of liver metastasis, experimentally and clinically. Liposomes composed of egg phosphatidylcholine (cholesterol 50 mol%) were used as drug carriers. We examined the distribution in tissues and antitumor effect of freeze-dried L-ADM administered via the portal vein to rabbits bearing VX2 tumors. The liver concentration of ADM increased after delivery and cardiac uptake decreased compared with free drug treatment. The life span was prolonged by L-ADM treatment compared with the control group and the free ADM group. This L-ADM administration was confirmed to be safe and revealed a decrease in the heart toxicities compared with free adriamycin. Nineteen cases were studied from Jan. 1986 to May 1991 via the portal vein and the clinical effects were evaluated. From Mar. 1988 to date, 10 cases were treated with L-ADM (20-30 mg every 2 weeks/body) in patients with inoperable cases using subcutaneously implanted reservoir. The median survival was 450 days; 275 days for colon cancer, 492 days for gastric cancer, and 1,052 days for uterine cancer (range: 136-1,152 days), compared with 141 days (range: 52-253 days) in 9 cases of historical control treated with free-ADM via the portal vein. These results suggest that chemotherapy via the portal vein with L-ADM for metastatic liver cancer may increase survival time.

The Cuban-born population of the United States, enumerated at 608,000 in the 1980 census, has been little studied with regard to cancer mortality. Being older and rarely migrating back to Cuba, Cuban Americans present a good subject for comparative cancer mortality. Age-adjusted death rates for selected causes of cancer are compared in this paper for Cubans in Cuba, the Cuban-born in the United States, and all whites in the United States. Two forms of cancer have been of particular concern in Cuba, cancer of the lung and cancer of the prostate, because of their relatively high death rates. The age-adjusted death rates for both of these cancers are lower among the Cuban-born in the United States than they are among Cubans in Cuba and whites in the United States. Death rates for cancer of the cervix and cancer of the rectum among the Cuban-born in this country are also low relative to Cubans in Cuba and whites in the United States. Stomach cancer mortality among Cuban-born men in the United States is lower than for men in Cuba or for white men in the United States, but Cuban-born women in this country have rates that are slightly higher than those of U.S white women. Mortality rates from colon cancer in both sexes and breast cancer among women are intermediate between the lower rates in Cuba and the higher rates among U.S. whites. Finally, the Cuban-born in the United States have higher death rates from cancer of the liver than do Cubans in Cuba or whites in the United States. In general, the profile found for the Cuban-born in the United States reflects the high socioeconomic status of the pre-1980 migrants as well as their exposure to the U.S. environment.

In order to improve therapeutic efficacy for metastatic liver cancer, intermittent transarterial administration of BRM in combination with anticancer drugs was performed by use of reservoir apparatus. A total of 22 patients (12 cases of gastric cancer, 6 of colon cancer, 2 of pancreas cancer, 1 of gall bladder cancer and 1 of biliary tract carcinoid) were treated according to the following schedule: both 10 mg of ADM (or MMC) and 0.5 KE (or 1.0 KE) of OK-432 were administered on day 1 and 40 x 10(4) JRU of recombinant interleukin 2 (r-IL 2) on day 4, 7 and 11. The treatment was repeated as many times as possible. In terms of direct antitumor effect and decrease of tumor marker, the response rate was 43% (6 cases out of 14) and 75% (9 cases out of 12), respectively. As for performance status, improvement, no change and deterioration were seen in 4 cases, 8 cases and 3 cases, respectively. Even though 13 patients died, 8 of them survived more than 300 days. In the case of gastric cancer patients with liver metastasis, 50% survival time of 12 cases was 334 days, while that of 30 cases, who were administered anticancer drugs only systemically, was 144 days. In 3 cases the decrease in the size of tumors located in both liver and the other metastases also was seen. Every case developed high grade fever, but an antifebrile was effective. Otherwise severe side effects were not seen. These results indicated that intermittent arterial infusion immunochemotherapy was feasible for the treatment of metastatic liver cancer.

The prognostic significance of nuclear DNA ploidy patterns and the S-phase fraction (labeling index; IL) were evaluated in 365 gastrointestinal tumors, and in 62 of them a combined analysis of DNA ploidy and the SPF was performed. For accurate evaluation, we used fresh frozen specimens, and we classified the ploidy pattern into 6 types; 1. diploid, 2. DS (diploid + high LI), 3. Notch, 4. Shoulder, 5. Tetraploid and 6. Aneuploid. Type 1 or type 2 tumors were classified as diploid, and the others were classified as aneuploid. In 103 cases of gastric cancer and 101 colon cancers due to the short observation period, but in 46 patients with operable primary liver cancer, a significant difference was observed. A high average of LI was detected in colon cancer (approximately 13%), but no relationship between LI and the ploidy pattern was found. This indicates that the LI may become an independent prognostic factor, and that the combined assay of DNA ploidy and the LI may offer a more precise evaluation of the malignant potential of gastrointestinal tumors.

Some factors relating to the increasing prevalence of postoperative infections after gastroenterological surgery were investigated from the standpoint of both patients profile and isolated bacteria. Data were collected from 542 cancer patients comprising 39 with esophagus cancer, 229 with gastric cancer, 149 with hepato-biliary tract and pancreatic cancer and 125 with colon cancer. Respiratory infections after operations were most frequently caused by aging, disturbance of glucose tolerance and respiratory dysfunction, whereas with intraabdominal abscess the major factors were disturbance of glucose tolerance, hepatic dysfunction and respiratory dysfunction in this order. Two factors in the management of patients during operation were singled out as mainly contributing to infection: these were prolonged operative time as in the case of esophagus cancer or hepato-biliary tract and pancreatic cancer, and massive intraoperative bleeding as in hepato-biliary tract, pancreatic and gastric cancer. As isolated bacteria, the most frequent clinical isolates were MRSA, Enterococcus, P. aeruginosa and Enterobacter, and it is noteworthy that all of these were strongly resistant to all antimicrobial agents. The greater emphasis on prevention control of postoperative infections, therefore, should be focussed on aging, preoperative risk factors, surgical stress and the kinds of antimicrobial agents administered.
