Abstract
Despite considerable advancements, the development of effective cancer screening tools based on serum biomarker measurements has thus far failed to achieve a meaningful clinical impact. The incremental progress observed over the course of serum biomarker development suggests that further refinements based on novel approaches may yet result in a breakthrough. The use of urine as an analytical biofluid for biomarker development may represent such an approach. The unique characteristics of urine including a high level of stability, ease of sampling, and an inactive and low-complexity testing matrix offer several potential advantages over the use of serum. A number of recent reports have demonstrated the utility of urine in the identification of novel cancer biomarkers and also the improved performance of biomarkers previously evaluated in serum. In this review, advancements related to the use of urine biomarkers within the settings of ovarian, breast, and pancreatic cancer are presented and discussed. Findings regarding the identification of specific urine biomarkers for each disease are highlighted along with comparative analyses of urine and serum biomarkers as diagnostic tools.

Abstract
Proteins that are expressed by both malignant and healthy fetal tissues are recognized as oncofetal. These antigens are associated with cell proliferation and differentiation and are produced in high concentrations in pregnancy and malignancy. Their biological role in malignancy is the suppression of the host's immune system, while in pregnancy they affect the maternal immune response, generating maternal tolerance toward the embryo. This review describes the levels of alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), carcinoembryonic antigen (CEA), cancer antigen 125 (CA 125), squamous cell carcinoma antigen (SCC), cancer antigen 15-3 (CA 15-3), mucin-like carcinoma-associated antigen (MCA), tissue polypeptide-specific antigen (TPS), carbohydrate antigen 19-9 (CA 19-9), and prostate-specific antigen (PSA) in maternal serum (MS), umbilical cord serum (UC), and amniotic fluid (AF) and outlines their roles in the assessment of pregnancy and malignancy. All antigens studied, except CA 15-3, are oncofetal. The presence of considerable concentrations of AFP, hCG, CEA, CA125, SCC, MCA, TPS, CA 19-9, and PSA in AF during pregnancy may be attributed to their involvement in biological functions associated with fetal development, differentiation, and maturation. MS CEA, CA 15-3, and CA 19-9, in contrast to all the others, are not influenced significantly by pregnancy and thus remain reliable tumor markers in monitoring malignancy in pregnant patients.

Abstract
INTRODUCTION Cyfra 21.1 are soluble cytokeratin 19 fragments present in several biological fluids. The aim of this work was to study cyfra 21.1 cytosolic levels in lung adenocarcinomas and their possible correlation with other clinical-biological parameters. PATIENTS AND METHODS Cyfra 21.1 was determined, using an immunoradiometric assay (CIS BioInternational. France), in 58 tissue samples of lung adenocarcinomas patients. Other parameters included in the study were the following: clinical stage, histological grade, ploidy, S-phase cellular fraction, as well as cathepsin D, CA 125 and hyaluronic acid levels in cytosols. Likewise, AH, erbB2 oncoprotein, CD44s, CD44v5 and CD44v6 levels in cell surfaces were assayed. RESULTS Cyfra 21.1 cytosolic levels oscillated between 24.8 and 6,774 ng/mg prot. (median 1,147.5) and were higher (p:0.00074) than those observed in 16 normal lung samples of the same patients. We did not observe any statistically significant differences in cyfra 21.1 values when clinical stage, ploidy, S-phase and histological grade were considered. When lung adenocarcinomas were classified according to cyfra 21.1 positivity, using 1,499 ng/mg prot. as cut-off, which represents the 75th percentile of the whole group, we noted that positive cases had higher levels of cathepsin D (p:0.00218), cytosolic hyaluronic acid (p:0.02947), erbB2 protein (p:0.06272) and CA 125 (p:0.07243) than negative carcinomas. CONCLUSIONS These results suggest the possibility that high cytosolic cyfra 21.1 levels could be associated with a poor outcome in lung adenocarcinomas.

Abstract
INTRODUCTION The tissue-specific polypeptide antigen (TPS) is an epitope of the tissue polypeptide antigen (TPA) which is defined by the M3 monoclonal antibody and is related to cytokeratin 18. Several groups have demonstrated its value as a useful parameter in the follow-up of some tumors. This work has aimed to study the TPS cytosolic levels in infiltrating ductal carcinomas of the breast (IDC) and their possible correlations with other clinical-biological parameters. PATIENTS AND METHODS The TPS was determined by means of an immunoradiometric assay (Beki Diagnostics. Sweden). Other parameters included in the study were the estrogen receptors (ER), progesterone receptors (PR), pS2, cathepsin D, tissue-type plasminogen activator (t-PA), tumor size, axillary lymph node involvement, distant metastases, histological grade, ploidy and S-phase. RESULTS The TPS cytosolic levels ranged from 1.8 to 606.3 KU/mg prt. (median 110.2) and had a significant correlation with the ER (r: 0.721), PR (r: 0.287), cathepsin D (r: 0.550) and t-PA (r:0.436). The TPS positive (> 110.2 KU/mg prt.) carcinomas had higher levels of ER (p: 0.001), PR (p: 0.021), pS2 (p: 0.058), cathepsin D (p: 0.000) and t-PA (p: 0.053) than the TPS negative tumors. When the IDC were classified according to S-phase values, we observed that the positive cases (S-phase > 8.1%, which represents the median value of all carcinomas) had lower levels of TPS (p: 0.046) than the negative tumors. Likewise, the GoG1 cellular fraction correlated positively and significantly with the TPS cytosolic levels (p: 0.000). CONCLUSIONS Based on our results, we suggest that there is a positive correlation between the TPS cytosolic levels and hormone-dependence parameters, as well as an inverse correlation between these and the cellular proliferation parameters. Based on the above, we consider that it is worthwhile to carry out further studies on cytosolic TPS in order to investigate its possible value as a prognostic parameter in breast carcinomas.

Abstract
Apoptosis is associated with caspase-mediated proteolysis of Type I (K18 and K19) cytokeratins. We previously showed a positive association between the levels of tissue polypeptide antigen (TPA), that recognizes cytokeratins K8, K18, and K19 fragments, and induced apoptosis in breast cancer cell lines. The aim of the present study was to evaluate the interrelationships between TPA, steroid receptors, and p53, and their joint prognostic role in node-negative breast cancer patients not treated with adjuvant therapies. Age and pT were also considered since they are known prognostic factors. Five hundred and ninety-nine cases with N- breast cancer were evaluated (median follow-up: 60 months). TPA was measured by an immunoradiometric assay and p53 by an immunochemiluminescent assay in tumor cytosol. Multiple correspondence analysis was used to study the associations among variables. Their prognostic role (univariate analysis) and their joint effect (multivariate analysis) on RFS were investigated with Cox regression models. TPA showed a direct association with ER and PgR. Higher p53 values were weakly associated to low values of ER, PgR, and TPA. Younger age was related to low and intermediate values of ER and PgR and to low p53 values, while older age was related to high values of ER. Multivariate analysis showed a significant prognostic impact for pT, age, ER, and TPA. Among the interactions considered clinically relevant, only that between ER and age was found. RFS estimated values were poorer in cases with lower than in those with higher TPA values, both in patients expected to have a poor (pT2, young age, low ER) and a better prognosis (pT1, older age, high ER). From the findings of the present study we can draw the following conclusions: The relationship of TPA with prognosis gives an additional contribution to pT, age, and steroid receptors in N- breast cancer; TPA may be considered the first marker of apoptosis measured with a fully standardized quantitative method in tumor cytosol and could be evaluated in prognostic indexes including markers related to different biological mechanisms.

Abstract
This retrospective study includes 425 serological examinations of 40 patients with epithelial ovarian cancer and 356 serological examinations of 33 patients with squamous cell cervical cancer. The serum levels of the tumor markers tissue polypeptide specific antigen (TPS), carbohydrate antigen 125 (CA 125) and squamous cell carcinoma antigen (SCC) were determined. Cutoff values of 93 U/l for TPS, 3 microg/l for SCC and 37 U/ml for CA 125 were selected according to the 95th percentile of serum concentrations measured in healthy control patients. For ovarian cancer sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of TPS were 67%, 84%, 59% and 90%, respectively. In 27 patients with recurrent ovarian cancer, CA 125 and TPS showed lead time effects in 8 and 11 cases, respectively. The combination of CA 125 and TPS provided lead time in 14 cases of recurrent disease with a time range from I to 23 months (median 3.9 months). In cervical cancer, TPS showed a sensitivity, specificity, PPV and NPV of 64%, 90%, 85% and 68%, respectively. In 16 patients with recurrent cervical cancer, SCC and TPS showed lead time effects in 7 and 8 cases, respectively. The combination of SCC and TPS provided lead time effects in 12 cases with a time range from 0.5 to 6 months (median 3.5 months). Our data indicate that TPS is a valuable tool in the follow-up of patients with ovarian or cervical cancer. However, TPS does not appear to be adequate to replace tumor markers CA 125 and SCC.

Abstract
Cytokeratins are polypeptides which constitute a subclass of intermediate filaments in epithelial cells. The serum tumour marker M3/M21 is based on monoclonal antibodies against the epitopes M3 and M21 of cytokeratin 18. In the present study, we measured M3/M21 serum levels in 50 patients with FIGO stage IB-IIB cervical cancer and in 50 control subjects using a two-site radiometric immunoassay directed against soluble fragments of cytokeratin 18. Median serum levels of M3/M21 in patients with cervical cancer and in normal controls were 70.6 U/ml (range 0-397.7) and 6.5 U/ml (range 0-205.2), respectively (Mann-Whitney U-test, P = 0.0001). Median serum levels of M3/M21 prior to therapy and 4 weeks after therapy were 104.2 U/ml (range 24.6-397.7) and 39.3 U/ml (range 0-234.7), respectively (Mann-Whitney U-test, P = 0.004). We found a significant correlation between elevated M3/M21 serum levels and metastatic disease in pelvic lymph nodes (Mann-Whitney U-test, P = 0.002). 24 patients relapsed after complete remission. In these patients, elevated M3/M21 serum levels before the detection of relapse by computed tomography was observed in 13 cases. Considering these preliminary results, further studies with an increased number of patients are justified to clarify the prognostic value and the monitoring abilities of M3/M21 in cervical cancer patients.

Abstract
In vitro research into hormone sensitivity and the relation to proliferation of cytokeratin release from cancer cells is scarce. Therefore, we examined the stimulation of proliferation and the release of cytokeratins in a breast cancer cell culture model. Cell growth was stimulated by 17 beta-oestradiol (10(-11) M), stripped serum (10%) and by the two together. Cytokeratin release was stimulated only by stripped serum, oestradiol having no effect. After long incubation periods (> 12 h), cytokeratin release also commenced in the control and oestradiol treatments. Release rate versus time analysis suggested that there are two different release processes. Cytokeratin release was first stimulated at a stripped serum concentration approximately 100 times lower than that which initiated proliferation. Pharmacological alteration of proliferation with cordyceptin resulted in growth changes without alterations in cytokeratin release. We conclude that cytokeratin release in these cells is unrelated to proliferation, independent of oestrogen action and probably in some way related to growth factor receptor function.

Abstract
Tissue polypeptide antigen, measured by both a polyclonal antibody (TPA IRMA Prolifigen) and a monoclonal antibody prototype kit (TPA-M IRMA Prolifigen), and the tissue polypeptide specific antigen were evaluated. The markers were measured in 266 serum samples and in 291 tumour cytosols from patients with primary breast cancer. The three markers were available in matched pairs of both serum and cytosol from the same patient in 144 cases. Diagnostic sensitivity of serum levels of the three markers was not significantly different when using cut-off values calculated on the basis of healthy subjects. In the cytosol, tissue polypeptide antigen (TPA IRMA), tissue polypeptide antigen (TPA-M IRMA) and tissue polypeptide specific antigen were significantly correlated with steroid receptor status, while their serum levels were not. Cytosol and serum levels of the three markers were not significantly associated. All three were significantly correlated both in serum and in cytosol. The association was closer between tissue polypeptide antigen (TPA IRMA) and tissue polypeptide antigen (TPA-M IRMA) than between each of these two markers and tissue polypeptide specific antigen. From these findings we draw the following conclusions: 1. Tissue polypeptide specific antigen (TPA IRMA) and tissue polypeptide antigen (TPA-M IRMA) probably provide superimposable information both in serum and in cytosol; 2. Tissue polypeptide specific antigen and tissue polypeptide antigen (TPA IRMA) or tissue polypeptide antigen (TPA-M IRMA), although closely associated, probably measure in part different cytokeratins. Therefore, they should not be considered interchangeable in individual patients; 3. The determination of the markers in serum and in cytosol provides different information concerning the tumour phenotype.
