In the present study, self-reported health care utilization of cancer survivors is compared with those of an age- and gender-matched normative population and predictors of health care utilization are identified. A population-based, cross-sectional survey among 1893 long-term survivors of endometrial and prostate cancer and malignant lymphomas (Hodgkin's and non-Hodgkin's) diagnosed between 1989 and 1998 was conducted using the cancer registry of the Comprehensive Cancer Centre South. Cancer survivors visited their general practitioner somewhat more often compared to the age and gender-matched general Dutch population but this effect was not always statistically significant. In addition, they visited their medical specialist significantly more often. Survivors only sporadically (0-3%) visited or required a dietician, sexologist, oncology nurse, pastor, creative therapy or recovery program. Contact with a psychologist, physiotherapist and other cancer survivors took place somewhat more often. Patients visited a medical specialist less often if they were diagnosed with endometrial cancer (OR = 0.2; 95% CI = 0.1-0.5), if they were diagnosed between 10-15 years ago (OR = 0.6; 95% CI = 0.1-0.5) and if they were not married or divorced (OR = 0.5; 95% CI = 0.3-0.9). Contact with a psychologist was related to having a university or college degree (OR = 3.6; 95% CI = 1.3-9.4). Cancer survivors visited their specialist more often compared to the normative population. Changes in health care, such as less administrative work for the specialist and more efficiency, are probably necessary in order to cope adequately with the increasing demand on the system.

Cancer is one of the most frequent disease-specific applications of the EQ-5D. The objective of this review was to summarise evidence to support the validity and reliability of the EQ-5D in cancer, and to provide a catalogue of utility scores based on the use of the EQ-5D in clinical trials and in studies of patients with cancer. A structured literature search was conducted in EMBASE and MEDLINE to identify papers using key words related to cancer and the EQ-5D. Original research studies of patients with cancer that reported EQ-5D psychometric properties, responses and/or summary scores were included. Of 57 identified articles, 34 were selected for inclusion, where 12 studies reported evidence of validity or reliability and 31 reported EQ-5D responses or summary scores. The majority of investigations using the EQ-5D concerned patients with prostate cancer (n = 4), breast cancer (n = 4), cancers of the digestive system (n = 7) and Hodgkin and/or non-Hodgkin lymphoma (n = 3). Mean index-based scores ranged from 0.33 (SD 0.4) to 0.93 (SD 0.12) and visual analogue scale scores ranged from 43 (SD 13.3) to 84 (SD 12.0) across subtypes of cancer. A substantial and growing body of literature using the EQ-5D in cancer that supports the validity and reliability of EQ-5D in cancer has emerged. This review provides utility estimates for cancer patients across a wide range of cancer subtypes, treatment regimens and tumour stage(s) that may inform the modelling of outcomes in economic evaluations of cancer treatment.

Carbaryl is a carbamate insecticide with a broad spectrum of uses in agricultural, commercial and household settings. It has previously been linked with non-Hodgkin lymphoma (NHL) but studies of cancer risk in humans are limited. We examined occupational carbaryl use and risk of all cancers in the Agricultural Health Study, a prospective study of a cohort of pesticide applicators in North Carolina and Iowa. This analysis included 21,416 subjects (1,291 cases) enrolled from 1993-1997 and followed for cancer incidence through 2003. Pesticide exposure and other data were collected using self-administered questionnaires. Poisson regression was used to calculate rate ratios (RRs) and 95% confidence intervals (CIs) while controlling for potential confounders. Carbaryl was not associated with cancer risk overall. Relative to subjects who never used carbaryl, melanoma risk was elevated with >175 lifetime exposure-days (RR = 4.11; 95%CI, 1.33-12.75; p-trend = 0.07), >10 years of use (RR = 3.19; 95%CI, 1.28-7.92; p-trend = 0.04), or >or=10 days of use per year (RR = 5.50; 95%CI, 2.19-13.84; p-trend < 0.001). Risk remained after adjusting for sunlight exposure. Although not significant, there appeared to be a trend of decreasing prostate cancer risk with increasing level of exposure. A small increase in NHL risk was observed using some, but not all, exposure measures. No associations were observed with other examined cancer sites. Because the observed results were not hypothesized a priori and because of limited study of their biological plausibility, they should be interpreted with caution.

Survival from cancer has improved over the past decade resulting in more long-term survivors. The literature on multi-dimensional quality of life (QOL) among long-term (5+ years) adult survivors is reviewed for each of seven cancer sites (i.e. breast, ovarian, cervical, prostate, colorectal, head and neck, and Hodgkin's disease survivors). Overall, long-term survivors experience good to excellent QOL. Physical domain QOL was the most frequently measured while spiritual domain QOL was the least frequently measured. QOL varies according to treatment received and by age for all groups with older persons (excepting head and neck and Hodgkin's disease survivors) reporting better QOL. QOL improves with time for breast cancer survivors and tends to decrease over time for prostate cancer survivors. Issues regarding sexual functioning affected the social domain-especially for breast and prostate cancer survivors. Social support improves psychological domain QOL for breast, cervical, and colorectal survivors. Review of findings may assist researchers and clinicians wishing to enhance the QOL of the long-term survivor population by identifying the most pressing and widely experienced concerns and by providing directions for future research.

Fifty-eight men at high risk of prostate cancer or with low-grade prostate cancer were randomly assigned to consume 1 of 3 protein isolates containing 40 g protein: 1) soy protein (SPI+, 107 mg isoflavones/d); 2) alcohol-washed soy protein (SPI-, <6 mg isoflavones/d); or 3) milk protein (MPI). Proliferating cell nuclear antigen (PCNA), epidermal growth factor receptor, B-cell non-Hodgkin lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax) were assessed in baseline and ending prostate biopsy cores. Serum collected at 0, 3, and 6 mo was analyzed for total and free prostate specific antigen (PSA). Consumption of SPI+ did not alter any of the prostate cancer tumor markers. Bax expression decreased from baseline in the SPI- group, resulting in lower Bax expression than the MPI group. PCNA expression also decreased from baseline in the SPI- group, but this was not different from the other 2 groups. PSA did not differ among the groups at 3 or 6 mo. Interestingly, a lower rate of prostate cancer developed in the soy groups compared to the milk group (P = 0.01). These data suggest that 6-mo SPI+ consumption does not alter prostate tissue biomarkers, SPI- consumption exerts mixed effects, and less prostate cancer is detected after 6 mo of soy consumption regardless of isoflavone content.

Prostate cancer (PCA) is one of the most invasive malignancy and second leading cause of cancer related deaths in United States and some other countries. Long latency period makes PCA an ideal disease for pharmacologic or nutritional chemoprevention. Lupeol, a triterpene present in mango and other fruits, has shown to possess anticancer properties in in vivo and in vitro assays. Here, we recorded the apoptogenic activity in mouse prostate by lupeol and mango pulp extract (MPE). Testosterone was injected subcutaneously (5 mg/kg body weight) for 14 consecutive days to male Swiss albino mice. Lupeol/MPE supplementation resulted in arrest of prostate enlargement in testosterone-treated animals. In mouse prostate tissue, lupeol and MPE supplementation resulted in a significantly high percentage of apoptotic cells in the hypodiploid region. The induction of apoptosis in mouse prostate cells was preceded by the loss of mitochondrial transmembrane potential and DNA laddering. In testosterone-induced mouse prostate, upregulation of antiapoptotic B-cell non-Hodgkin lymphoma-2 and downregulation of proapoptotic Bcl-2-associated X protein and caspase-3 were also recorded. We further observed apoptogenic activities of lupeol in an in vitro model using human prostate cancer cells [lymph node carcinoma of the prostate (LNCaP)]. The apoptogenic response of lupeol-induced changes in LNCaP cells can be summarized as early increase of reactive oxygen species followed by induction of mitochondrial pathway leading to cell death. Thus, the results of this study demonstrate that lupeol/MPE is effective in combating testosterone-induced changes in mouse prostate as well as causing apoptosis by modulating cell-growth regulators.

Epigallocatechin-3-gallate (EGCG) is the major and most potent polyphenol compound of green tea that has been shown to have anticancer effects against various types of cancers. In this study, in addition to the EGCG compound, a synthetic derivative, the peracetate of EGCG (EGCG-P), was used to investigate the inhibitory effects on growth of androgen-independent prostate cancer in vivo. The advantage of EGCG-P is that it may act as a prodrug, leading to higher bioavailability than EGCG itself. The aim of our study was to compare the differences between EGCG and EGCG-P on their inhibitory effect on androgen-independent prostate cancer, CWR22R, xenograft model in nude mice. The mice were administrated daily with solvent dimethyl sulfoxide, EGCG, and EGCG-P separately through intraperitoneal injection for 20 days. Tumor volume and body weight of nude mice were recorded daily. Serum prostate-specific antigen (PSA) levels were also measured before and after the treatment. The effects of both EGCG and EGCG-P on tumor cell proliferation were assessed by immunohistochemical (IHC) method using antibodies against Ki-67 and proliferating cell nuclear antigen. The apoptotic effect was evaluated by IHC against B-cell non-Hodgkin lymphoma-2 and terminal deoxynucleotidyl transferase dUTP nick-end labeling assay by in situ apoptosis detection kit. Moreover, the potential suppression of angiogenesis by EGCG and EGCG-P on prostate cancer was examined by IHC against CD31. Our results revealed that treatment of EGCG and EGCG-P compounds suppressed the growth of CWR22R xenografts without causing any detectable side effects in nude mice. The suppression of growth of the tumor was correlated with the decrease of serum PSA level together with the reduction in tumor angiogenesis and an increase in apoptosis on prostate cancer cells. The results showed that treatment of EGCG and EGCG-P inhibited tumor growth and angiogenesis while promoting apoptosis of the prostate cancer cells in vivo. Our results suggest that EGCG-P may be a more stable and useful compound for increasing the therapeutic anticancer effects in androgen-independent prostate cancer.

Aromatic amines (AAs) and polycyclic aromatic hydrocarbons (PAHs) are carcinogens present in tobacco smoke and functional polymorphisms in NAT2 and GSTM1 metabolizing genes are associated with increased bladder cancer risk. We evaluated whether genetic variation in other candidate metabolizing genes are also associated with risk. Candidates included genes that control the transcription of metabolizing genes [aryl hydrocarbon receptor (AHR), AHRR and aryl hydrocarbon nuclear translocator (ARNT)] and genes that activate/detoxify AA or PAH (AKR1C3, CYP1A1, CYP1A2, CYP1B1, CYP3A4, EPHX1, EPHX2, NQO1, MPO, UGT1A4, SULT1A1 and SULT1A2). Using genotype data from 1150 cases of urothelial carcinomas and 1149 controls from the Spanish Bladder Cancer Study, we estimated odds ratios (ORs) and 95% confidence intervals (CIs) adjusting for age, gender, region and smoking status. Based on a test for trend, we observed 10 non-redundant single-nucleotide polymorphisms (SNPs) in five genes (AKR1C3, ARNT, CYP1A1, CYP1B1 and SULT1A2) significantly associated with bladder cancer risk. We observed an inverse association with risk for the AKR1C3 promoter SNP rs1937845 [OR (95% CI) for heterozygote and homozygote variant compared with common homozygote genotype were 0.86 (0.70-1.06) and 0.74 (0.57-0.96), respectively; P for trend = 0.02]. Interestingly, genetic variation in this region has been associated with lung, non-Hodgkin lymphoma and prostate cancer risk. Analysis of additional SNPs to capture most (approximately 90%) of common genetic variation in AKR1C3 and haplotype walking analyses based on all AKR1C3 SNPs (n = 25) suggest two separate regions associated with bladder cancer risk. These results indicate that genetic variation in carcinogen-metabolizing genes, particularly AKR1C3, could be associated with bladder cancer risk.

Serum determinations of CA125 and prostate-specific antigen (PSA) have been useful in monitoring the status of ovarian and prostate cancer, respectively. However, these antigens are not specific for these neoplasms and ignorance of that fact may lead to confusion in certain settings. Serum CA125 can be elevated in many benign and malignant conditions in which coelomic epithelium is involved. Although lymphoma cells do not secrete CA125, several investigators have reported serum elevations of CA125 in as many as 40% of patients with non-Hodgkin lymphoma (NHL), particularly when peritoneal, pleural, or pericardial effusions are present. In such patients, CA125 levels appear to correlate with disease activity, whereas levels prior to treatment have correlated with disease-free and overall survival in some, but not all, studies. A number of investigators have suggested including serum CA125 levels in prognostic indices for lymphoma. PSA elevations have been reported in patients with NHL less frequently than CA125 elevations, but the PSA in such cases appears to be secreted by the lymphoma cells themselves. The available data are reviewed here.

Human arylamine N-acetyltransferases (CoASAc; NAT, EC 2.3.1.5) NAT1 and NAT2 play a key role in the metabolism of drugs and environmental chemicals and in the metabolic activation and detoxification of procarcinogens. Phenotyping analyses have revealed an association between NAT enzyme activities and the risk of developing several forms of cancer. As genotyping procedures have become available for NAT1 and NAT2 gene variations, hundreds of association studies on NAT polymorphisms and cancer risk have been conducted. Here we review the findings obtained from these studies. Evidence for a putative association of NAT1 polymorphism and myeloma, lung and bladder cancer, as well as association of NAT2 polymorphisms with non-Hodgkin lymphoma, liver, colorectal and bladder cancer have been reported. In contrast, no consistent evidence for a relevant association of NAT polymorphisms with brain, head & neck, breast, gastric, pancreatic or prostate cancer have been described. Although preliminary data are available, further well-powered studies are required to fully elucidate the role of NAT1 in most human cancers, and that of NAT2 in astrocytoma, meningioma, esophageal, renal, cervical and testicular cancers, as well as in leukaemia and myeloma. This review discusses controversial findings on cancer risk and putative causes of heterogeneity in the proposed associations, and it identifies topics that require further investigation, particularly mechanisms underlying association of NAT polymorphisms and risk for subsets of cancer patients with specific exposures, putative epistatic contribution of polymorphism for other xenobiotic-metabolising enzymes such as glutathione S-transferases of Cytochrome P450 enzymes, and genetic plus environmental interaction.
