This study was undertaken to determine the nuclear DNA content in the primary and recurrent ovarian carcinoma of the same 20 consecutive patients by flow cytometry, and the results on clinical outcome was examined. The tissue samples of the recurrent tumors were obtained at second-look laparotomy. Of the primary tumors, 12 were diploid, 4 were pure aneuploid, and 4 were \"mosaic\", while of the recurrent tumors, 17 were diploid and 3 showed pure aneuploid. No significant difference of the DNA index at recurrence was observed. DNA ploidy was preserved in 12 out of 20 patients at recurrence. The time to recurrence after the initial treatment showed no significant difference versus DNA ploidy and change of ploidy. The sites and status of recurrence differed by DNA ploidy. At recurrence, the patients with DNA diploidy had a tendency to survive longer than those with DNA aneuploidy. The determination of DNA ploidy at recurrence may be useful as a variable parameter in predicting the survival of patients with ovarian carcinomas.","PeriodicalId":76232,"journal":{"name":"Nihon Gan Chiryo Gakkai shi","volume":"25 12","pages":"2836-42"},"PeriodicalIF":0.0,"publicationDate":"1990-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13229669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we investigated serum levels of alpha-fetoprotein (AFP) and thymidine kinase (TK), DNA-synthesizing enzyme in the salvage pathway, and tissue TK and its isozyme activities in the liver of rats treated with 3'-MeDAB. Serum TK activities rose abruptly right after the onset of 3'-MeDAB treatment, peaking after one week and then gradually decreasing. At 3 weeks, though serum TK was decreasing, serum AFP and tissue TK began to increase, and oval cells appeared in the liver. At 5 weeks, though serum TK reached a nadir, serum AFP and tissue TK formed transient peaks, and oval cells occupied a major part of the hepatic lobules with hyperplastic nodules. Thereafter, serum TK continued to increase, and serum AFP and tissue TK, after transiently decreasing, re-increased; at 20 weeks, each value was at high level, and mixed type hepatocarcinoma was observed. The liver TK isozymes were separated into 3 types by DEAE-cellulose column chromatography. A 3'-MeDAB induced a remarkable increase in activity of cytosolic and fetal type isozyme in non-tumorous regions of livers at 5 weeks and tumorous regions at 20 weeks. These results indicate that biochemical changes in 3'-MeDAB-treated rat liver may provide a valuable insight into two step process in hepatocarcinogenesis.","PeriodicalId":76232,"journal":{"name":"Nihon Gan Chiryo Gakkai shi","volume":"25 12","pages":"2794-801"},"PeriodicalIF":0.0,"publicationDate":"1990-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13229793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Positive rates of each marker prior to the treatment were as follows; PA; 75%, PAP; 56% and gamma-Sm; 62% in stage C, and PA; 95%, PAP; 79% and gamma-Sm; 91% in stage D. In most cases showing PR (partial response) and S (stable) in clinical responses, these three markers decreased their serum titers corresponding to clinical course if the markers were elevated at the start of the treatment. But the usefulness of PAP was lessened because of its lower positive rate than those of PA and gamma-Sm. In 33 PD (progressive disease) cases, positive rates of each marker at time of clinical diagnosis as PD were found to be 85% in PA, 55% in PAP and 76% in gamma-Sm. And with the combination assays of these three tumor markers, positive rate was elevated to 88%. Moreover, elevation of serum values of these three markers at 3 months before the progression event were observed in 50% of PA, 39% of PAP and 46% of gamma-Sm. Then the prognostic significance of each marker was examined. In PA and PAP, there were statistical differences in non-relapsing rates between patients whose reduction rates from the pretreatment value on 7th day were more than and less than 50%. But in gamma-Sm, a statistical difference between each group was firstly observed on 14th day. As a result, in monitoring patients with prostate cancer, PA and gamma-Sm are more useful than PAP and, in prediction of patients' prognosis, PA is more useful than gamma-Sm.","PeriodicalId":76232,"journal":{"name":"Nihon Gan Chiryo Gakkai shi","volume":"25 11","pages":"2627-39"},"PeriodicalIF":0.0,"publicationDate":"1990-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12867703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, not only do they present with varied clinical symptoms, some forming tumors or erythemas, some being infiltrative in nature and some being flat in shape, but the clinical symptoms also vary with time during treatment. All these conditions conspire to make the evaluation of chemotherapeutics complicated and difficult. In the field of dermatology topical drugs provide a no less powerful weapon than drugs for systemic administration with which to combat skin carcinomas and are simple and easy to administer. In consideration of those clinical and therapeutic aspects of malignant skin carcinomas new evaluation criteria for chemotherapeutics for topical and systemic administration have been established by adding three-way measurement to the conventional methods of one- and two-way measurement for measurable lesions along with the evaluation of the response of clinical symptoms to chemotherapeutics in unmeasurable carcinomas. The new version of criteria is based in its general framework on the Japan Society for Cancer Therapy's Evaluation Criteria for Chemotherapeutics for Solid Carcinomas by Koyama and Saito and the new version has been approved at the 26th general meeting of the Japan Society for Cancer Therapy (1988, Niigata).","PeriodicalId":76232,"journal":{"name":"Nihon Gan Chiryo Gakkai shi","volume":"25 11","pages":"2609-20"},"PeriodicalIF":0.0,"publicationDate":"1990-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13427391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatment after around 1983 involved the use of biological response modifier (BRM), chiefly interferon (IFN), and operation by thoracoabdominal approach. Before that, chemotherapy, radiotherapy and operation by peritoneal approach were used, with many cases judged inoperable. Even in non-operative cases, life-prolongation was frequently achieved by embolization of the renal artery and administration of various BRMs. On the other hand, in cases judged operable which were always treated by resection, early postoperative death sometimes occurred. These facts brought home to us the difficulty of choosing appropriate treatment. Though it is hard to determine the relative merits of various treatments from the present data, since the series is small and contains cases from 1963 onwards, the clinical and pathological pictures should be carefully evaluated for each case, and the most suitable course of treatment should be selected individually. We describe a non-operative case in which a combined use of embolization, IFN-gamma and tumor necrosis factor (TNF) elicited a lasting partial response, and an operative case in which postoperative complications such as pulmonary infarction and renal failure occurred after operation under extracorporeal circulation and patient died at 2 months after operation.","PeriodicalId":76232,"journal":{"name":"Nihon Gan Chiryo Gakkai shi","volume":"25 11","pages":"2621-6"},"PeriodicalIF":0.0,"publicationDate":"1990-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13427392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
