Ten episodes of Torulopsis glabrata fungemia occurring in nine patients with terminal illnesses are described. Eight patients had underlying malignancies and one patient had a plastic anemia. Two episodes of fungemia were considered transient since they were clearly related to the administration of intravenous hyperalimentation (IVH). Most patients were adult women and had solid tumors of the genitourinary tract. Contributory factors were: antibiotic therapy (100%), immunosuppressive drugs (75%), abdominal surgery (63%), IVH (50%), neutropenia (38%), and diabetes mellitus (13%). The clinical course was indistinguishable from a severe bacterial infection. However, endotoxic shock was not observed. The infection was rapidly fatal in four patients. In the remaining five patients, the infection was altered favorably by the discontinuation of infected intravenous hyperalimentation catheters. However, tissue invasion by T. glabrata was found in two of these patients who died shortly thereafter from tumor progression. At autopsy, T. glabrata was identified in tissue sections of the lungs, kidneys, and mucosas of the gastrointestinal and genitourinary tracts. In all cases there was tissue necrosis with a minor inflammatory response consisting of mononuclear cells. To our knowledge, this is the single largest series of T. glabrata fungemia ever reported.

Since 1975, seven groups of investigators have reported clinical results of interstitial brachytherapy (IBT) for pancreatic cancer. The reports are comprised of data from 254 patients, 21 of whom died in the postoperative period for an overall operative mortality rate of 8.7%. Operative mortality rate range from 0% to 32% in individual reports. Most patients have been treated with 125I, although 25 patients were treated with 198Au seeds. Most investigators report combining IBT with external beam radiation therapy (EBRT) +/- adjuvant chemotherapy. In general, IBT has been associated with considerable morbidity. Median patient survival time has not exceeded 15 months. This report describes an additional seven patients with locally unresectable pancreatic cancer, without distant metastases, treated primarily with 60 to 100 Gy matched peripheral dose (MPD) by 125I IBT. One patient died postoperatively of a pulmonary embolus. Four of the remaining six patients were also treated with modest doses (10.5 to 30 Gy) of EBRT late in the course of the disease for local tumor progression. One developed a pancreaticocutaneous fistula, and one developed exacerbation of pre-existing diabetes mellitus. The median patient survival time from the date of IBT was 7 months (range: 0 to 21 months). One patient is alive without clinical evidence of cancer 9 months after IBT.

One hundred and one cases of hepatocellular carcinoma (HCC) treated in Maebashi Red Cross Hospital from May 1984 to August 1987 were classified according to the therapy and progression of the disease and were investigated on their prognosis. Furthermore, "long survived group" in which, patients survived for more than one year were compared with "short survived group" in which patients died within one month after non-surgical treatment. In operated patients, the prognosis was the best, but the rate of operable cases was only 13.9%. In patients with stage IV, one year survival rate was significantly low. In patients with portal trunk invasion (Vp4), or with Child C that was the poorest functional reserve of the liver, one year survival rate was also significantly low in comparison with patients with other stages or other Child's classification. In HCC patients treated with transcatheter arterial embolization (TAE), the prognosis tended to be poor as stage and portal invasion progressed, but in regard to reserve function of the liver, the prognosis was not so poor in patients of Child C significantly as in cases of A or B. The comparisons between long and short survived group were as follows. a) In 17 cases belong to long survived group, mean survival period was 24 months and the longest one was 4 years and 10 months. On the other hand, in 10 cases belong to short survived group, mean survival period was 17 days, the shortest one was 3 days. b) The main reason of inoperability in long survived group was progression of the tumor. Complications such as diabetes mellitus, advanced age and rejection of treatment by the patient were the other reasons of in operability. In almost half of the patients in short survived group, the tumor progression and low functional reserve of liver were found in 4 patients. c) In short survived group, esophageal varices were more common and functional reserve of the liver was poorer than in long survived group. In short survived group, LDH and total bilirubin were significantly higher than those of long survived group, but there was no significant differences in transaminase value and ICG retention in 15 minutes. d) In short survived group, extent of the tumor in liver and portal invasion were advanced. Three cases of this group (30%) had distant metastasis. e) In long survived group, the main reason of death was hepatic failure. Renal failure, or pulmonary complications were also found in short survived group.(ABSTRACT TRUNCATED AT 400 WORDS)

The long-acting somatostatin analog (octreotide) was administered to a 37-yr-old woman with the ectopic ACTH syndrome. The patient had diffuse metastatic spread of a nonpituitary tumor, presumably of pancreatic origin, and severe and rapidly progressive hypercortisolism with extreme myopathy, hypokalemia, and diabetes mellitus. Plasma ACTH and lipotropin levels and 24-h urinary cortisol excretion were greatly elevated [218 pg/mL (48 pmol/L), 1340 pg/mL (220 pmol/L), and up to 830 micrograms/24 h (2290 nmol/day), respectively]. Urinary cortisol excretion decreased to normal within 3 days after the initiation of octreotide therapy (150, 300, and 600 micrograms/day), and plasma ACTH and lipotropin levels also decreased. Urinary cortisol excretion remained normal for 2 months during chronic octreotide therapy, and her general condition improved dramatically. The only side-effect was a slight increase in the number of bowel movements. Tumor progression, however, was not controlled, and she eventually died of hepatic insufficiency. These data indicate that octreotide can be a highly effective treatment for patients with the ectopic ACTH syndrome.

Blood tissue polypeptide specific antigen (TPS) concentration was serially measured by IRMA radioimmunodetective procedure in hormonally treated prostate cancer patients with Stage Do-D1 tumor (20 subjects free of bone lesions) and Stage D2 disease (20 subjects with bone metastases). Monoclonal antibody against the principle M3-TPA epitope was used in this TPS assay. Serum TPS values were compared with respective blood prostate specific antigen (PSA), prostatic acid phosphatase (PAP), carcinoembryonic antigen (CEA) and testosterone levels in a retrospective manner. A control group included healthy men, patients with benign prostatic hypertrophy (BPH), subjects with inflammation of the prostate, and men with diabetes. PSA is reported to be a quantitative calibration for prostate cancer load in untreated patients, especially during early stages of the disease. In hormonally treated, advanced, and dedifferentiated prostatic carcinoma this serotest fails to reflect properly both tumor status and response to treatment. In Stage Do-D1 patients TPS concentrations remain normal or become slightly elevated even during local tumor progression. This finding is in accord with the slow proliferation of nonaggressive primary tumors. Circulating TPS concentrations are elevated in progressive metastatic patients, in the majority of Stage D2 subjects with stable disease and even in some of these patients during partial tumor remission. This latter result may be attributed not only to the heterogeneity of the advanced prostatic cancer but also to the actual tumor response to treatment, since serum PSA level fails to reflect properly the outcome of hormonal treatment. There is some evidence that an abrupt elevation in serum TPA level in such patients is a consequence of NK cell-mediated lysis of circulating tumor cells, thus giving rise to a simultaneous and rapid delivery of intracellular TPS into the bloodstream. Prostatic inflammation elevates TPS concentrations only slightly, while diabetes, even during a proper treatment, raises TPS concentration more intensely. In patients with BPH normal or slightly increased TPS values were measured. The results ot these preliminary investigations seem to open the way for further prospective studies.

To evaluate the clinical efficacy of interferon-alpha in hepatocellular carcinoma, 71 adult Chinese patients with histologically proven inoperable hepatocellular carcinoma were randomized to receive recombinant interferon-alpha 2a (50 x 10(6) IU/m2) intramuscularly three times a week (n = 35) or no antitumor therapy (n = 36). The survival of interferon-alpha-treated patients was significantly better than that of patients who received no antitumor therapy (p = 0.0471); median lengths of survival were 14.5 and 7.5 wk, respectively. Objective tumor regression greater than 50% was observed in 31.4% (11 of 35) of patients receiving interferon-alpha. Interferon-alpha induced tumor regression greater than 50% in 11 (31.4%) patients. Compared with the group receiving no antitumor therapy, the interferon-alpha therapy group had more tumor regression (p < 0.0001) and less tumor progression (p = 0.001). This high-dose interferon-alpha therapy was relatively well tolerated; only 34.3% of patients required reduction of dosage by one third or one half because of persistent fatigue. Two patients with diabetes mellitus (one also had tabes dorsalis) exhibited mental deterioration that might have been partially attributable to interferon-alpha therapy. We conclude that interferon-alpha is useful in a proportion of Chinese patients with inoperable hepatocellular carcinoma, both in prolonging survival and in inducing tumor regression.

Endocrine organs, such as the pancreatic islets of Langerhans, contain permeable, fenestrated endothelium that allows direct access of endocrine cells to the blood stream. Factors that control differentiation and maintenance of this highly specialized endothelium remain unknown. Vascular endothelial growth factor (VEGF) is a multifunctional growth factor that may be responsible for the homeostasis of endocrine endothelium; it is a selective mitogen for endothelial cells and is able to permeabilize endothelium. We have analyzed the expression of VEGF mRNA and protein in pancreatic islet cells of normal mice and during the different stages of tumor progression in a transgenic mouse model of beta-cell carcinogenesis. The 120-amino acid and the 164-amino acid isoforms of VEGF are expressed in normal islets of Langerhans and are moderately up-regulated during the stages of tumor development. Two high-affinity receptors for VEGF, flt-1 and flk-1, are expressed by endothelial cells both in normal islets and in the stages of tumorigenesis; these receptors are not up-regulated during this process. Our data raise the possibility that VEGF is involved in the maintenance of permeable endothelium in islets of Langerhans, an observation that may have implications for islet cell physiology and diabetes. While VEGF may also play an important role in the growth of new blood vessels during islet cell tumorigenesis, it cannot be the only factor required for the activation of tumor angiogenesis.

Oncogene amplification is frequent in many epithelial tumors and often associated with advanced tumor progression. In different epithelial neoplasias it helps to provide prognostic information on individual patients. The present study was performed to evaluate the hitherto unknown prevalence of INT-2 gene amplification and its potential usefulness as prognostic marker in patients with human thyroid cancer. We used differential quantitative polymerase chain reaction and fluorescent DNA technique as a reliable method to detect low copy-number amplification of oncogenes from archival carcinoma specimens. Sequences from the int-2 gene and the single copy gamma-interferon gene were amplified simultaneously by PCR and quantified on a fluorescence activated sequencer. Native tumor tissue from 63 patients with differentiated thyroid cancer (43 papillary, 3 oncocytary, and 17 follicular) and from 12 goiters was analyzed by differential quantitative polymerase chain reaction. The study group contained many far advanced tumors. 40% of tumors were recurrent, 35% were staged T4 tumors and 70% presented with lymph node metastases. The prevalence of INT-2 amplification was 12% for follicular and 7% for papillary carcinomas. In goiter tissue no amplification was found. Amplification was only 2-4fold in positive cases. Low grade amplification is of no apparent importance in differentiated thyroid cancer.

Contradictary results have been reported indicating both increased and reduced risks for malignancies in diabetic patients. This may possibly be due to difficulties in the clinical diagnosis of carcinomas and inaccuracies in the determination of diabetic conditions in the autopsy studies. Since glomerular microangiopathy is a typical feature of long-term diabetes, we performed a retrospective statistical analysis on 5000 consecutive, non-selected autopsy cases with particular reference to the presence/absence of microangiopathy in diabetic individuals. In our study group, we found a total incidence of 9.8% (n = 488) diabetic patients of which 213 (4.3%) had a histologically confirmed significant glomerulosclerosis and a total of 34% patients with verified carcinoma (n = 1699). The age- and sex ratios were matched between diabetic, non-diabetic and carcinoma patients. Systemic and coronary arteriosclerosis were significantly higher in diabetics than non-diabetics (p < 0.0001). Most interestingly, the rate of carcinomas in the diabetic group with nodular and diffuse glomerulosclerosis was 2.5- (p < 0.0001) and 1.9-fold (p < 0.0027), respectively, lower than in the non-diabetic group. In addition, the statistical evaluation showed in the glomerulosclerotic diabetic group significantly lower rates of metastasis. Our retrospective statistical analysis on an unselected series of autopsy cases thus provides evidence that diabetes mellitus with glomerulosclerosis is associated with a significantly lower frequency of carcinomas when compared to individuals without renal microangiopathy. Since TGF-beta is assumed to play a crucial role both in diabetes and carcinogenesis/tumor progression, our findings suggest an altered cell-matrix interaction in diabetes, possibly exerted by chronic TGF-beta overexpression.

We have identified human 17beta-hydroxysteroid dehydrogenase type 7 (17beta-HSD 7). The novel human cDNA encodes a 37 kDa protein that shows 78 and 74% amino acid identity with rat and mouse 17beta-HSD 7, respectively. These enzymes are responsible for estradiol production in the corpus luteum during pregnancy, but are also present in placenta and several steroid target tissues (breast, testis and prostate) as revealed by RT-PCR. The human 17beta-HSD 7 gene (HSD17B7) consists of nine exons and eight introns, spanning 21. 8 kb and maps to chromosome 10p11.2 close to susceptibility loci for tumor progression, obesity and diabetes. The HSD17B7 promoter (1.2 kb) reveals binding sites for brain-specific and lymphoid transcription factors corresponding to additional expression domains in hematopoietic tissues and the developing brain as identified by in silico Northern blot.
