Mitoxantrone prepared by Shanghai Institute of Pharmaceutical Industry is reported. 154 patients with various advanced cancers confirmed by pathology were treated by mitoxantrone with a dose of 14 mg/M2, i. v., once every 3 or 4 weeks from Feb. 1985 to Feb. 1987. There were 96 males and 58 females. The ages ranged from 16 to 76 years with an mean age of 48 +/- 15. Objective response rates were 21% in breast cancer, 36% in non-Hodgkin's lymphoma, 56% in acute lymphocytic leukemia, 14% in acute nonlymphocytic leukemia, 31% in gastric cancer and 5% in primary hepatic cancer. The side effects were leukopenia and gastro-intestinal disturbances. No marked cardiac toxicity was observed.

Cause-specific mortality patterns among Rhode Island jewelry manufacturing workers, as identified on death certificates from 1968 to 1978, were examined using the proportionate mortality ratio (PMR) method. Among males, elevated PMRs were observed for nonmalignant kidney disease (PMR = 163; Observed deaths [Obs] = 19; p less than or equal to .05), liver cancer (PMR = 297; Obs = 6; p less than or equal to .05), drug dependence (PMR = 379; Obs = 5; p less than or equal to .05), and accidental poisonings (PMR = 274; Obs = 8; p less than or equal to .05). All but one of the deaths from accidental poisonings involved drugs or drugs and alcohol. Among females, elevated PMRs were observed for stomach cancer (PMR = 174; Obs = 20; p less than or equal to .01), peptic ulcer (PMR = 235; Obs = 8; p less than or equal to .05), diseases of the skin and subcutaneous tissue (PMR = 383; Obs = 5; p less than or equal to .05), and drug dependence (PMR = 674; Obs = 3; p less than or equal to .05). Exposure to known renal toxins (heavy metals and solvents) used in the jewelry industry may account for the excess deaths from kidney disease. The elevated PMR for liver cancer may be due to exposure to solvents (trichloroethylene, perchloroethylene, carbon tetrachloride) that cause liver cancer in animals. The elevated PMRs for drug dependence and accidental poisonings may be due to the socioeconomic status of jewelry workers, or to the interaction between solvents used in jewelry manufacturing and drugs, or drugs and alcohol. Because of the lack of information about the specific occupational exposures of the decedents, this should be viewed as an exploratory investigation requiring further follow-up.

Monoclonal antibody (A9-84) against a hepatocellular carcinoma cell line (PLC/PRF-5) was produced by somatic cell fusion. The hybridoma clones were screened by a rapid solid-phase enzyme-linked binding assay. The target cells were cultured in 96-well Linbro plate and fixed by methanol for screening. The specificity of the antibody was studied by enzyme-linked binding assay and immunofluorescence methods. It shows that A9-84 do not respond to 8 different human cancer cell lines (4 liver cancer, 1 esophageal cancer, 1 stomach cancer, 1 multiple myeloma and 1 lymphoblast cell line) and the peripheral mononuclear cells of 91 normal subjects. A9-84 is the subtype of IgG3. It is capable of inhibiting the growth of cultured PLC/PRF/5 cells with or without complement.

So far as is known, this is the first reported case in the literature of a primary cystic liver cancer complicated with a gastric cancer. A 77-year-old female was admitted to hospital because of a swelling in the upper abdomen and appetite loss. CT scanning, an echogram, and an angiogram of the abdomen revealed a large cystic lesion which originated from the left lobe of the liver. A DIC indicated a gall stone, Further, upper GI fluoroscopy and endoscopy revealed a gastric cancer of the Borrmann II type, and thus a dome resection of the cyst, cholecystectomy, aad 3/4 partial gastrectomy was performed. The liver was found to contain much mucin. The histology indicated a cystadenocarcinoma of the liver, and an adenocarcinoma of the stomach of a poorly differentiated type.

Potential risks of gastrointestinal cancers after cholecystectomy were examined among 1238 patients who had had their gallbladders extirpated for benign biliary diseases from 1951 to 1970. The observed deaths between 1953 and 1984 were compared with the expected values which were calculated from death rates in Japan. No appreciable excess mortality was found for stomach cancer, colorectal cancer or pancreas cancer in relation to cholecystectomy. Observed and expected deaths during the whole observation period were 29 vs. 31.58 for stomach cancer, 8 vs. 6.50 for colorectal cancer overall, 5 vs. 3.19 for colon cancer and 3 vs. 3.51 for pancreas cancer. The corresponding figures in the 10 years or more after cholecystectomy were 14 vs. 19.06 for stomach cancer, 5 vs. 4.66 for colorectal cancer and 3 vs. 2.38 for colon cancer. A notably increased mortality from liver cancer was observed, but it was considered to be related not to cholecystectomy itself but to blood transfusion.

Based on the overall results of a UFT phase II study made in 104 institutions in Japan from April of 1979 to September of 1980, there was a response rate of 27.7% with 3 CR cases and 49 PR cases out of 188 stomach cancer cases considered as evaluable according to solid cancer chemotherapy direct efficacy criteria. Other response rates were spleen cancer 25%, gallbladder cancer 25%, liver cancer 19.2%, colorectal cancer 25%, breast cancer 32% and lung cancer 7%. Side effects out of 551 cases were, loss of appetite 24.3%, nausea/vomiting 12.5%, diarrhea 11.1% and other digestive system symptoms mainly. The hematologic side effects were mild, being 6.9%. According to the UFT phase II study, in 438 evaluable cases followed for 5 years after testing, the results were analyzed in terms of therapeutic efficacy and survival time. In 185 stomach cancer cases, 50% survival time was 185 days, with CR + PR cases 336 days, MR + NC cases 183 days, and PD cases 97 days. Colorectal cancer showed a 50% survival time of 227 days in 54 cases, while that for 49 breast cancer cases was 505 days. Total Ftorafur (FT) results using the same criteria from the UFT phase II study revealed, from a comparison of dosage and disease type, that UFT did not enhance FT side effects; rather, it markedly increases effectiveness. Therefore, on the basis of its response rate and the survival time for the cases of digestive system cancer, UFT is considered an effective anticancer agent.

Mortalities from selected sites of cancer among 5,130 male Japanese physicians followed up for 19 years were examined in relation to smoking and drinking habits surveyed in 1965. With smoking habit classified into three categories (never/past, 1-19 and greater than or equal to 20 cigarettes/day) and drinking habit into four (never/past, occasional, less than 2 and greater than or equal to 2 go of sake/day), the effects of the two factors and their combined effect were analyzed by using the Cox proportional hazard model. Interaction of smoking and drinking was found to be negligible for the sites of cancer studied (upper aerodigestive tract, esophagus, stomach, large bowel, liver and lung), and independent relationships of smoking and drinking with upper aerodigestive cancer were confirmed. Smoking, besides being strongly associated with lung cancer, was also weakly, but significantly, related to stomach cancer. Liver cancer showed no association with smoking whereas this cancer was significantly related to alcohol consumption. The present findings provide further evidence for the association between cigarette smoking and stomach cancer but do not support the relationship recently suggested between smoking and liver cancer.

An earlier case-referent study by the same authors [Int Arch Occup Environ Health 54 (1984) 147-153] reported that solvent-exposed women, but not men, had an increased risk for primary liver cancer. The present study was undertaken to verify these results. The relatives of deceased patients, ie, 377 liver cancer cases, 385 coronary infarction referents, and 476 stomach cancer referents, responded to a questionnaire on past employment and potentially relevant covariables, the response rates being 71.7, 72.7, and 69.0%, respectively. The information was assessed for solvent exposure by two occupational hygienists without knowledge of the patients' diagnoses. Seven male and seven female liver cancer cases had been exposed to solvents, the odds ratio being less than 1 for the men but greater than 3 for the women irrespective of the reference group used for comparison. The results confirm the authors' earlier findings. When both materials were combined, the odds ratio was 7.8 for the female liver cancer cases as compared with the infarction referents. In the combined material, nine female liver cancer cases, two stomach cancer referents, but no infarction referent had had at least probable exposure to chlorinated hydrocarbons. Such exposure was rare among all of the men in the study. This finding may explain why the increased liver cancer risk occurred only for the women, although a sex difference in sensitivity cannot be completely ruled out.

A review of epidemiological studies on the health effects of exposure to phenoxy herbicides suggests that exposure may be associated with an increased incidence of cancer and unfavorable outcomes of pregnancy. Studies on cancer have found increased risks of 5.3, 6.8 and 3.96 for soft-tissue sarcoma, 7.7 and 6.0 for stomach cancer, 2.05 for lung cancer, 4.8 for lymphoma, 2.3 for all cancers combined, and 5.2 for liver cancer after exposure to 2,4,5-T or dioxin contaminants. Several studies have suggested a possible increase in birth defects after paternal exposure. An increased risk of hydatidiform mole is suggested by Vietnamese studies on the effects of maternal exposure.

This article updating cancer chemotherapy of gastrointestinal cancer completes the fivepart series begun in the April issue of the Journal. Treatment of cancer of the small intestine, the gallbladder and bile duct, primary cancer of the liver, and the esophagus are reviewed in this concluding article.Treatment of choice of cancer of the small intestine is surgical resection. Small bowel cancer is less responsive than gastric cancer to chemotherapy. While chemotherapy may produce temporary partial remissions in patients with gallbladder and bile duct cancer, there is no evidence that it produces longterm survival time. In primary liver cancer, surgery is the only curative treatment, but only 30 percent of patients are diagnosed with resectable lesions, and the surgical mortality rate is high. The most active single agents appear to be doxorubicin, fluorouracil, and neocarcinostatin. Data on combination chemotherapy are limited.With carcinoma of the esophagus, 95 percent of patients die of the condition. The standard treatment for locoregional disease is surgical resection and/or radiation therapy. Chemotherapy has been slow to develop; single-agent chemotherapy has been reported to be active in 15 percent of cases with durations of 2 to 5 months. Combination chemotherapy is so recent that data are incomplete as to long-term results of disease-free and total survival times, but polychemotherapy appears to be more effective than single agents.With earlier detection, prompt surgery, earlier chemotherapy, improved dose scheduling, and further exploration of combination therapy, better overall results with a major impact years later may be expected. Because of the lack of data, there remains uncertainty as to the place of chemotherapy in the treatment of gastrointestinal cancer.
