    ABSTRACT: Breast cancer is less common in China than in the United States and perinatal characteristics predict breast cancer risk in the offspring. We determined levels of pregnancy hormones in Boston and Shanghai to identify those possibly involved in the intrauterine origin of breast cancer. Participants and methods: We compared maternal and cord blood levels of estradiol, estriol, testosterone, progesterone, prolactin, insulin-like growth factors (IGF) 1 and 2, insulin-like growth factor-binding protein 3, adiponectin and sex hormone-binding globulin (SHBG) in 241 Caucasian and 295 Chinese women. In both centers, hormone levels at the 16th were predictive of those at the 27th gestational week, but there was little correlation between maternal and cord blood levels. In cord blood, we found significantly (P < 0.01) higher levels of estradiol (44.2%), testosterone (54.5%), IGF-2 (22.7%) and strikingly SHBG (104.6%) in Shanghai women, whereas the opposite was true for IGF-1 (-36.8%). Taking into account the current understanding of the plausible biological role of the examined endocrine factors, those likely to be involved in the intrauterine origin of breast cancer are SHBG and IGF-2, with higher cord blood levels among Chinese, and IGF-1, with higher cord blood levels among Caucasian women.

    ABSTRACT: Breast cancer incidence and birth weight are higher among Caucasian than Asian women, and birth size has been positively associated with breast cancer risk. Pregnancy hormone levels, however, have been generally lower in Caucasian than Asian women. We studied components of the insulin-like growth factor (IGF) system in cord blood from 92 singleton babies born in Boston, USA, and 110 born in Shanghai, China, in 1994-1995. Cord blood IGF-1 was significantly higher among Caucasian compared with Chinese babies (P<10(-6)). The opposite was noted for IGF-2 (P approximately 10(-4)). IGF-1 was significantly positively associated with birth weight and birth length in Boston, but not Shanghai. In contrast, stronger positive, though statistically non-significant, associations of IGF-2 with birth size were only evident in Shanghai. The associations of birth weight and birth length were positive and significant in taller women (for IGF-1 in Boston P approximately 0.003 and 0.03, respectively; for IGF-2 in Shanghai P approximately 0.05 and approximately 0.04, respectively), among whom maternal anthropometry does not exercise strong constraints in foetal growth. The documentation of higher cord blood levels of IGF-1, a principal growth hormone that does not cross the placenta, among Caucasian than in Asian newborns is concordant with breast cancer incidence in these populations.

    ABSTRACT: Considerable progress has been made in improving the control of chemotherapy-induced emesis. The impact of available antiemetic options for patients receiving stem cell transplants is unclear, as few prospective data have been collected. We prospectively evaluated antiemetic outcome in patients receiving stem cell transplantation over a 7-day period following the initiation of chemotherapy. The primary endpoints were the number of emetic episodes and the extent of nausea measured on a four-point scale. Eighty-two patients were evaluated. Ninety-five percent of patients had nausea during the first week of treatment; 80% had at least one emetic episode. The percentage of patients with emesis was as follows: day 1: 13%, day 2: 21%, day 3: 30%, day 4: 38%, day 5: 44%, day 6: 39%, day 7: 18%. In multivariate analysis, gender, emesis with prior chemotherapy, history of morning or motion sickness, type of transplant (auto vs allo), use of total body irradiation, or use of dexamethasone did not effect emesis control. Most patients receiving high-dose chemotherapy experience incompletely controlled emesis. Control of nausea and emesis progressively worsened with each subsequent day following initiation of chemotherapy, reaching a nadir on day 5. New treatment approaches are needed to improve emesis control in this patient population.

    ABSTRACT: In a population-based case-control study in Yangzhong, China, we investigated the relationship between genetic polymorphisms of GSTP1 and susceptibility to gastric cancer and its premalignant lesion, chronic gastritis. The possible gene-gene interactions between GSTP1 polymorphisms and GSTM1, GSTT1 genes were explored. Epidemiologic data were collected by standard questionnaire from 133 gastric cancer cases, 166 chronic gastritis cases, and 433 cancer-free population controls. Blood samples for Helicobacter pylori and molecular marker assays were collected from 84 gastric cancer cases, 146 chronic gastritis, and 429 population controls. GSTP1 polymorphisms were determined by the PCR-RFLP method and H. pylori infection was measured by the ELISA method. Associations between certain GSTP1 genotypes and both gastric cancer and chronic gastritis were assessed by odds ratios (ORs) and 95% confidence intervals (CIs) derived from logistic regression. The distributions of three GSTP1 genotypes, Ile/Ile, Ile/Val, and Val/Val, were similar in gastric cancer cases, chronic gastritis, and controls. After adjusting for age, gender, education, body mass index, pack-year of smoking, alcohol drinking, H. pylori infection, salt and fruit intakes, the adjusted ORs of Val/Val were 1.3 (95% CI: 0.1-11.2) for gastric cancer and 0.9 (95% CI: 0.2-4.8) for chronic gastritis. Combining the Val alleles (Val/Val and Ile/Val) into one group, no association was observed between GSTP1 and both gastric cancer and chronic gastritis. In addition, the allelism at the GSTP1 locus did not increase gastric cancer and chronic gastritis risks associated with the GSTM1 or GSTT1 genotypes. Our data suggest that the GSTP1 genotype seems not to be associated with the risk of gastric cancer and chronic gastritis in a high-risk Chinese population.

    ABSTRACT: Obesity has been associated with an increased risk of renal cell cancer among women, while the evidence for men is considered weaker. We conducted a quantitative summary analysis to evaluate the existing evidence that obesity increases the risk of renal cell cancer both among men and women. We identified all studies examining body weight in relation to kidney cancer, available in MEDLINE from 1966 to 1998. The quantitative summary analysis was limited to studies assessing obesity as body mass index (BMI, kg m(-2)), or equivalent. The risk estimates and the confidence intervals were extracted from the individual studies, and a mixed effect weighted regression model was used. We identified 22 unique studies on each sex, and the quantitative analysis included 14 studies on men and women, respectively. The summary relative risk estimate was 1.07 (95% CI 1.05-1.09) per unit of increase in BMI (corresponding to 3 kg body weight increase for a subject of average height). We found no evidence of effect modification by sex. Our quantitative summary shows that increased BMI is equally strongly associated with an increased risk of renal cell cancer among men and women.

    ABSTRACT: Umbilical cord blood is an alternative stem cell source for patients without matched family donors. In this study, we examined several parameters that have not been studied in detail -- radiation dose, cell dose, age of mice, and maternal and neonatal characteristics of the cord blood donor -- that affect engraftment of cord blood in non-obese diabetic-severe combined immunodeficient (NOD--scid) mice. Engraftment, measured using flow cytometry analyses of human CD45(+) cells, was highest in 400 cGy-treated mice. Successful engraftment was demonstrated up to 6 months, with a mean engraftment of 31% (range 0--67%) of human cells in recipient bone marrow. Engraftment was skewed to B lymphocytes. The radiation dose of 350 cGy resulted in superior survival of the murine recipients compared with 400 cGy (P = 0.03). The sex of the NOD--scid recipients had a significant effect on survival (female superior to male, P = 0.01), but not on engraftment. There were high levels of variability among different cord units and among animals injected with the same cord unit. This variability may limit the clinical usefulness of the NOD--scid mice as hosts for the quantification of human stem cells.

    ABSTRACT: To explore possible associations between the reproductive history amongst women and the risk of parathyroid adenoma (PA). Two nationwide Swedish registries. The Fertility Register included data on more than 3.4 million livebirths between 1943 and 1992 amongst Swedish females born 1925-72. The Cancer Register encompasses more than 1800 women with a diagnosis of PA 1960 until 1992. All women resident in Sweden 1960-92. Cases were all 1800 women born 1925-72 reported to the Swedish Cancer Registry with a histopathological diagnosis of PA. Five controls were selected at random for each case by matching for the month and year of birth. Conditional logistic regression was used to estimate relative risks of PA. Parathyroid adenoma. High parity (four or more live births) was associated with an increased risk of PA. Amongst women with a diagnosis of PA before menopause (i.e. the age of 50 years) there was an increased risk of PA with younger age at first childbirth. Nulliparous women were at increased risk for PA before menopause, and at decreased risk after menopause. There is an association between childbearing and the risk of PA, which has not previously been demonstrated, but the underlying biological mechanisms remain to be determined.

    ABSTRACT: Despite the declining trend, stomach cancer remains the second most common cancer worldwide. We examined the role of green tea consumption on chronic gastritis and stomach cancer risks. A population-based case-control study was conducted in Yangzhong, China, with 133 stomach cancer cases, 166 chronic gastritis cases, and 433 healthy controls. Epidemiologic data were collected by standard questionnaire and odds ratios (OR) and 95% confidence intervals (CI) were estimated using logistic regression models in SAS. Inverse association was observed between green tea drinking and chronic gastritis and stomach cancer risks. After adjusting for age, gender, education, body mass index, pack-years of smoking and alcohol drinking, ORs of green tea drinking were 0.52 (95% CI: 0.29-0.94) and 0.49 (95% CI: 0.31-0.77) for stomach cancer and chronic gastritis, respectively. In addition, dose-response relationships were observed with years of green tea drinking in both diseases. The results provide further support on the protective effect of green tea against stomach cancer. This is the first time that green tea drinking was found to be protective against chronic gastritis, which may be of importance when designing intervention strategies for stomach cancer and its pre-malignant lesions in the high-risk population.

    ABSTRACT: The insulin-like growth factor (IGF) axis has important autocrine, paracrine, and endocrine roles in the promotion of growth. Alterations of the IGF system have recently been implicated in the pathogenesis of several malignancies, but the relation to hepatocellular carcinoma (HCC) risk is unclear. To address this issue, we used an immunoradiometric assay to quantify IGF-1 levels in serum samples in a hospital-based, case-control study in Greece. The study subjects were all men and included 53 patients with HCC positive for hepatitis B and/or hepatitis C virus infections, 20 virus-negative HCC patients, 25 virus-negative patients with metastatic liver cancer (MLC), and 111 virus-negative control subjects. Data were analyzed by multiple linear regression, using IGF-1 as the dependent variable. The mean value of IGF-1 was 65.9 ng/ml among virus-positive HCC patients, 79.5 ng/ml among virus-negative HCC patients, 110.8 ng/ml among patients with MLC, and 174.7 ng/ml among hospital controls. After controlling for the degree of liver damage, as assessed by prothrombin time and serum albumin level, the reduction in IGF-1 level among HCC patients was found to be more than could be attributed to liver damage alone. This finding may have both diagnostic and pathophysiological implications.

    ABSTRACT: Diet appears to be a major determinant in the incidence of prostate cancer. In a case-control study conducted in Athens, Greece, we found that dairy products, butter and seed oils were positively associated with risk of prostate cancer, whereas cooked and raw tomatoes were inversely associated. We utilized the data from this study to calculate the population attributable fractions under alternative assumptions of feasible dietary changes. For each subject, a dietary score was calculated and categorized into approximately quintiles, representing increasing levels of prostate cancer risk as a function of the intake of the five discriminatory food groups or items. Population attributable fractions in terms of this dietary score were calculated taking into account multivariate adjustment. We observed that, if all individuals were shifted to the baseline category, the incidence of prostate cancer in this study population would be reduced by 41% (95% confidence interval 23-59%). However, if all individuals were shifted to the adjacent lower risk quintile, the expected incidence reduction would be a more modest 19%. The incidence of prostate cancer in Greece could be reduced by about two-fifths if the population increased the consumption of tomatoes and reduced the intake of dairy products, and substituted olive oil for other added lipids.

    ABSTRACT: Umbilical cord blood transplantation is considered an alternative to traditional bone marrow transplantation for patients who do not have matched sibling donors. In this study, we examined the effects of ex vivo treatment of human cord blood cells with cytokine mixtures and assessed the ability of treated cells to engraft in NOD-scid mice. We incubated the cord blood with a four-factor cytokine mixture of interleukin (IL)-3, IL-6, IL-11 and stem cell factor, or with a two-factor cytokine mixture of thrombopoietin and flt-3. Incubation of cord blood for 48 h with either cytokine mixture did not affect progenitor cell number or proliferative potential as measured by the high proliferative potential (HPP) assay. Cytokine-treated cord blood injected into irradiated NOD-scid mice resulted in multilineage human engraftment. Overall, incubation with cytokines resulted in variable levels of engraftment with different cord blood samples. Incubation of cord blood with the four-factor cytokine mixture resulted in increased survival of irradiated NOD-scid recipients. These results demonstrate that short-term ex vivo treatment of human progenitor cells gives variable results on in vivo multipotential capabilities.

    ABSTRACT: During a 4-year period from January 1995 to December 1998, blood samples and questionnaire data were obtained from 333 incident cases of hepatocellular carcinoma (HCC), as well as from 360 controls who were hospitalized for eye, ear, nose, throat or orthopedic conditions in Athens, Greece. Coded sera were tested for hepatitis B surface antigen (HBsAg) and antibodies to hepatitis C virus (anti-HCV) by third-generation enzyme immunoassays, and information on smoking habits and beverage consumption was obtained. We found a significant dose-response, positive association between smoking and HCC risk [>/= 2 packs per day, odds ratio (OR)=2.5]. This association was stronger in individuals without chronic infection with either HBV or HCV (>/= 2 packs per day, OR=2.8). Consumption of alcoholic beverages above a threshold of 40 glasses per week increased the risk of HCC (OR=1.9). We also found evidence of a strong, statistically significant and apparently super-multiplicative effect of heavy smoking and heavy drinking in the development of HCC (OR for both exposures=9.6). This interaction was particularly evident among individuals without either HBsAg or anti-HCV (OR for both exposures=10.9). Coffee intake was not positively associated with HCC risk, but the reverse could not be excluded for the subgroup of chronically infected individuals. In conclusion, tobacco smoking and heavy alcohol consumption are associated with increased risk of HCC, especially when these 2 exposures occur together.

    ABSTRACT: To determine whether tea consumption and intake of other beverages increases bladder cancer risk. A case-control study was conducted in Kaohsiung, Taiwan between August 1996 and June 1997. Index patients studied were consecutive patients with histologically confirmed, newly diagnosed bladder cancer in two major hospitals. For each patient, 4 controls were selected from patients with non-neoplastic and nonurologic diseases undergoing surgical operations in the same hospital and individually matched by sex, age, and date of admission. Using a structured questionnaire, a trained interviewer interviewed 40 patients and 160 controls. Conditional logistic regression analysis adjusting for ethnicity, family history, and smoking status and matching variables were used to estimate the odds ratio (OR) and 95% confidence interval (CI). Tea consumption overall was associated with increased bladder cancer risk (OR 3.29, 95% CI 1.34 to 8.05). Compared with non-tea drinkers, the odds ratios of bladder cancer for oolong tea drinkers was 3.00 (95% CI 1.20 to 7.47); for non-oolong tea drinkers (black and/or other green tea), it was 14.86 (95% CI 2.13 to 103.83). The risk was greater among those who began to drink tea before age 40 (OR 9.50, 95% CI 2.39 to 37.75) and those who had been drinking tea for more than 30 years (OR 17.75, 95% CI 3.00 to 105.17). Coffee, tap water, and alcohol consumption were associated with a slightly increased risk, and both soy juice and rice juice consumption were associated with reduced risk; none of these odds ratio estimates were statistically significant, however. Our results suggest that tea consumption is associated with an increased risk of bladder cancer.

    ABSTRACT: To evaluate the nutritional etiology of benign prostatic hyperplasia (BPH) by conducting a case-control study in Athens, Greece. Despite the high morbidity and substantial human suffering produced by BPH, little research has been undertaken concerning the nutritional etiology of this disease. The study sample consisted of 184 patients with histologically confirmed BPH and 246 control patients without clinical evidence of prostate disease. All patients and controls were permanent residents of the greater Athens area. The data were modeled through unconditional logistic regression. Among the food groups, fruits were inversely related to BPH risk, with a logistic regression-derived odds ratio of 0.79 per quintile increase and 95% confidence interval 0.67 to 0.93. Increased consumption of both butter and margarine was positively associated with BPH risk, and a marginally significant positive association was also evident for seed oils. No overall association was found with respect to consumption of olive oil. In analyses evaluating the role of nutrients rather than foods, zinc, an element selectively concentrated in the prostate gland, was significantly positively associated with BPH risk. Our study provides evidence that, among added lipids, butter and margarine may increase the risk of BPH, and fruit intake may reduce this risk. Dietary zinc may play an important role in the etiology of BPH.

    ABSTRACT: A case-control study of prostate cancer (PC) was undertaken in Athens, Greece. Cases were 320 patients with histologically confirmed incident disease, whereas controls were 246 patients without history or symptomatology of benign prostatic hyperplasia, treated in the same hospitals as the cases for minor diseases or conditions. Cases and controls had similar distributions with respect to height, body mass index, sibship size and birth order in the parental family, marital status and number of offspring in the subject's own family and a long series of previous surgical operations and medical diagnoses, including diabetes mellitus, hepatitis and sexually transmitted diseases. There was also no evidence for a positive association between vertex baldness, tobacco smoking and drinking of coffee or alcoholic beverages, on the one hand, and PC, on the other. There was evidence, however, that some aspect of urban life may increase the risk for PC and a suggestion that sexual activity in early adulthood may be inversely associated with this risk.

    ABSTRACT: Hematopoietic progenitor cells are incubated with cytokine combinations for in vitro expansion of stem cells and to enhance retrovirus-mediated gene transfer. Optimization of the engraftment of these treated cells would be critical to the success of stem cell transplantation or gene therapy. Previous studies demonstrated that a 48-hour incubation of donor BALB/c bone marrow with a mixture of four cytokines (IL-3, IL-6, IL-11, and SCF), resulted in expansion of primitive progenitor/stem cells but a loss of long-term engraftment in nonmyeloablated or myeloablated recipients. We have established the expression pattern for a number of adhesion receptors by normal hematopoietic progenitors and cell lines and the modulation in expression induced by cytokines or cell cycle progression to ascertain the molecular basis for such defective engraftment. Northern blot analysis demonstrated that the cytokine combination of IL-3, IL-6, IL-11, and SCF dramatically down-regulated alpha 4 integrin receptor expression in HL-60 cells. Synchronized FDC-P1 cells exhibited modulation of alpha 4 expression through cell cycle progression, both by quantitative RT-PCR and flow cytometry. Normal murine bone marrow lineage-depleted, Sca+ cells expressed a number of adhesion receptors, including alpha L, alpha 1, alpha 3, alpha 4, alpha 5, alpha 6, beta 1, L-selectin, CD44, and PECAM as assessed by flow cytometry, immunofluorescence, and RT-PCR. There was modulation of the expression of several of these receptors after incubation in the four cytokines for 24 and/or 48 hours: the proportion of cells expressing alpha L, alpha 5, alpha 6, and PECAM increased, whereas the proportion of cells expressing alpha 4 and beta 1 decreased, after cytokine incubation. There was a demonstrable concomitant decline in adhesion of these cells to fibronectin after the cytokine incubation, a finding that correlates with the decrease in expression of alpha 4. These changes in adhesion receptor expression and function with cytokines and during cell cycle transit may be critical to stem cell homing and engraftment after transplantation, as multiple receptors could be involved in the process of rolling, attachment to endothelium, endothelial transmigration, and migration within the marrow space.
