Abstract
Aims and Background Carcinoembryonic antigen (CEA) belongs to a family of cell surface glycoproteins. Its level in serum has a significant value for the follow-up and treatment of patients with malignancies. The aim of this study was to correlate the concentration of tumor cytosol CEA (cCEA) with tumor size, patient age and sex, clinical stage, lymph node metastases, and overall survival rate in primary non-small cell lung carcinoma (NSCLC). Methods and Study Design The cCEA levels were determined in 76 NSCLC patients by luminescence assay (LIA) and radioimmunoassay (RIA). Results A strong correlation between LIA and RIA assay results was found (r = 0.992). No correlation was observed between serum CEA and cCEA levels. Tumors smaller than 3 cm had significantly higher cCEA levels than larger tumors, but when a logistic modeling process was applied this difference was not significant (P = 0.038). Histologically well-differentiated tumors also showed a significantly higher expression of cCEA (P <0.05). In addition, patients without lymph node involvement had higher cCEA levels than patients with tumor-positive lymph nodes (P <0.05). Univariate statistical analysis revealed that the risk of lymph node metastases was 1.8-fold higher in patients with low cCEA levels than in patients with higher levels, taking the median value as cutoff (P = 0.04, Kruskal-Wallis test). Conclusions According to the results of our study, patients with overexpression of cCEA may have a better prognosis than those with low cCEA expression. cCEA might therefore be considered a good prognostic parameter as well as a prognostic factor independent of the traditional parameters for lymph node metastases.

Abstract
Forty-nine healthy subjects (Group I), 24 patients with benign lung diseases (Group II) and 48 patients surgically treated for lung cancer (Group III): 28 with squamous cell carcinoma (SCC) and 20 with adenocarcinoma (adenoca), were tested for the presence of carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA), cancer antigen CA 125 and antigen CA 15.3. The four markers were measured in the serum of the patients of the three groups and in the cytosol extract of tumoral and peritumoral tissues of Group III subjects. The mean levels of serum CEA and TPA were significantly higher in squamous cell carcinoma and in adenocarcinoma patients than in normal subjects. In benign lung disease serum CEA was equal and TPA slightly higher than in normal subjects. CA 125 was higher in the serum of patients with malignant diseases compared to normal or benign lung diseases but this difference was not statistically significant. Serum CA 15.3 levels were similar in all subjects studied. CA 125 in squamous cell carcinoma cytosol was much higher than in peritumoral cytosol whereas the other three markers were not significantly different in tumor cytosol or peritumoral cytosol. A direct correlation between serum and cytosol values was observed for CEA, but not for the other markers. The levels of the four markers in serum and cytosol did not correlate with the stage or grade of the tumors.

Abstract
CEA was initially described as a tumor and organ specific colorectal antigen, but later found by more sensitive methods in other tumors (stomach, pancreas, lung, breast) and in minor amounts in inflammatory, normal adult and fetal organs of the gastrointestinal tract. The main clinical application of CEA concerns its pretherapeutic and serial determination as circulating antigen in serum and other body fluids by means of CEA-specific, commercially available test kits. By clinical studies a significant correlation has been proven between the pretherapeutic serum CEA level and tumor stages and prognosis. Moreover, serial CEA level changes have been shown a valuable monitor following operation or during radio/chemotherapy anticipating and reflecting the clinical course of disease. In combination with newly established tumor markers, the main clinical indication for CEA determination in addition to colorectal cancer concerns monitoring of patients with stomach (+ CA 72-4), lung (+ NSE/SCC) and breast cancer (+ CA 15-3/MCA).

Abstract
Lung cancer is a devastating illness with an overall poor prognosis. To effectively address this disease, early detection and novel therapeutics are required. Early detection of lung cancer is challenging, in part because of the lack of adequate tumor biomarkers. The goal of this review is to summarize the knowledge of current biomarkers in lung cancer, with a focus on important serum biomarkers. The current knowledge on the known serum cytokines and tumor biomarkers of lung cancer will be presented. Emerging trends and new findings in the search for novel diagnostic and therapeutic tumor biomarkers using proteomics technologies and platforms are emphasized, including recent advances in mass spectrometry to facilitate tumor biomarker discovery program in lung cancer. It is our hope that validation of these new research platforms and technologies will result in improved early detection, prognostication, and finally the treatment of lung cancer with potential novel molecularly targeted therapeutics.

Abstract
Background The aim of this study was to evaluate the significance of albumin in bronchial washing fluid (BWF) and its relationship to three tumor markers (CEA, CA 19–9 and NSE). Methods Serum and BWF samples were collected in a group of 60 patients. Albumin and tumor markers in the BWF and serum of three groups: a control group (CG), a chronic bronchitis group (CBG) and a lung cancer group (CaG), were analyzed in a prospective cross-sectional study. The diagnostic yields of the tests in each environment (serum and BWF) were evaluated by using as cutoff points the values of the corresponding 90th percentile of CG and CBG taken together. Results A significant difference in albumin level (p<0.001) was noted in the BWF of patients with cancer compared with the other two groups. In addition, a significant difference in CEA level (p<0.001) was observed in the serum of cancer patients compared with the other two groups. The cutoff values for CEA in serum and albumin in BWF were 2.20 ng/mL and 2.00 g/dL, respectively. The areas under the corresponding ROC curves were 93% and 97%. Combination of CEA-serum and albumin-BWF by logistic regression analysis increased their diagnostic value. Conclusion Measurement of albumin levels in BWF could be a useful additional diagnostic tool to differentiate malignant from non-malignant lung diseases. Moreover, the combined measurement of CEA in serum and albumin in BWF could be of aid in the follow-up of lung cancer patients.

Abstract
BACKGROUND Neuron-specific enolase (NSE) is a well known marker of small cell lung cancer. The present study was designed to assess the clinical value of NSE in non-small cell lung cancer (NSCLC), as compared to that of carcinoembryonic antigen (CEA) and tissue polypeptide antigen (TPA). METHODS The study comprised 448 new consecutive NSCLC patients seen from 1996 to 2001. A set of 30 anthropometric, clinical, physical, laboratory, radiological, and pathological variables was prospectively recorded for all patients. Patients were carefully followed-up, and their subsequent clinical course recorded. RESULTS Increased values of NSE were present in 32% of the patients. Bivariate analyses showed that NSE, TPA and CEA were significantly correlated with each other, lactate dehydrogenase, tumour diameter, and disease extent. Univariate analyses showed that patients with elevated concentration of both NSE and TPA had significantly shorter survivals than patients with low values (30 [95% CI: 25-35] vs. 61 weeks [46-76], and 30 [CI: 24-36] vs. 59 weeks [40-79], respectively, P=0.0000). The Cox proportional hazards model including all the 22 variables significant in univariate analysis selected, in decreasing order of significance, the following variables: (1) N factor; (2) main treatment; (3) ECOG PS; (4) CNS metastasis; (5) age; (6) tumour cavitation; (7) NSE; (8) T factor; and (9) adrenal gland metastasis. CONCLUSIONS This data indicates that serum assay of NSE is a useful marker also in NSCLC and a significant predictor of survival, independently of the other prognostic factors.

Abstract
BACKGROUND In the current study, we report the carcinoembryonic antigen (CEA) capability to predict early tumor relapses after a pulmonary resection for nonsmall cell lung cancer (NSCLC). METHODS We studied 118 consecutive NSCLC patients who were clinically judged operable and were eventually operated upon. Anthropometric, clinical, and CEA data along with the results of both preoperative and postoperative stage classifications were recorded. All patients were followed up for at least 1 year after surgery and the time to the first clinical recurrence recorded. Receiver-operating characteristic (ROC) curves and diagnostic formulas were used for data analysis. RESULTS In this series the CEA test was among the most accurate methods to predict an early postoperative recurrence (ROC area: 0.72, 95% confidence interval [CI]: 0.60 to 0.85, p = 0.001; accuracy rate for CEA at the threshold of 10 ng/mL: 83%, CI: 76% to 90%). Also predictive was the postoperative pathologic stage of disease (ROC area: 0.68, CI: 0.56 to 0.80, p = 0.007). In tumors pathologically classified in stage Ia to IIb, a preoperative CEA level higher than 10 ng/mL was associated with a 67% probability of tumor relapse. In the same stages of disease, a CEA level less than 10 ng/mL increased the baseline probability of no recurrence from 80% to 88%. CONCLUSIONS In operable patients with NSCLC the frequency of abnormal serum concentrations of CEA is low (17% in our series). However, it is important to identify such a small group of high-risk patients as many of them (in our study, 55% and 70% of those with a CEA value in excess of, respectively, 5 and 10 ng/mL) will develop an early postoperative recurrence. Such patients should be investigated preoperatively by mediastinoscopy or positron emission tomography in even in the absence of suspicious symptoms and signs. Then after an apparently successful operation, they should be carefully followed up. These patients could represent a suitable target for neoadjuvant clinical trials of selected high-risk groups.

Abstract
STUDY OBJECTIVES To provide a systematic overview of the literature investigating patient and tumor factors that are predictive of survival for patients with non-small cell lung cancer (NSCLC), and to analyze patterns in the design of these studies in order to highlight problematic aspects of their design and to advocate for appropriate directions of future studies. DESIGN A systematic search of the MEDLINE database and a synthesis of the identified literature. MEASUREMENTS AND RESULTS The database search (January 1990 to July 2001) was carried out combining the MeSH terms prognosis and carcinoma, nonsmall cell lung. Eight hundred eighty-seven articles met the search criteria. These studies identified 169 prognostic factors relating either to the tumor or the host. One hundred seventy-six studies reported multivariate analyses. Concerning 153 studies reporting a multivariate analysis of prognostic factors in patients with early-stage NSCLC, the median number of patients enrolled per study was 120 (range, 31 to 1,281 patients). The median number of factors reported to be significant in univariate analyses was 4 (range, 2 to 14 factors). The median number of factors reported to be significant in multivariate analyses per study was 2 (range, 0 to 6 factors). The median number of studies examining each prognostic factor was 1 (range, 1 to 105 studies). Only 6% of studies addressed clinical outcomes other than patient survival. CONCLUSIONS While the breadth of prognostic factors studied in the literature is extensive, the scope of factors evaluated in individual studies is inappropriately narrow. Individual studies are typically statistically underpowered and are remarkably heterogeneous with regard to their conclusions. Larger studies with clinically relevant modeling are required to address the usefulness of newly available prognostic factors in defining the management of patients with NSCLC.

Abstract
OBJECTIVES Copious literature shows that in lung cancer many serum markers, especially the cytokeratin degradation products, correlate with the extent of disease. In 1995, we suggested the possibility of predicting the resectability of non-small cell lung cancer by measuring the plasma level of the tissue polypeptide antigen, a marker of the cytokeratin family. This study was designed (1) to confirm the earlier data in a new prospective evaluation, (2) to comparatively assess another classic biomarker (ie, the carcinoembryonic antigen), and (3) to incorporate their results into the preoperative evaluation of non-small cell lung cancer. METHODS We analyzed the database of a single institution over a 5-year period (1994-1998) in a community-based hospital and second referral level institution for a province of 500,000 people. The database included 124 consecutive patients (105 men) with pathologically documented lung cancer (50% with adenocarcinoma) accurately staged, clinically judged operable or potentially operable, and eventually operated on. Anthropometric, clinical, and laboratory data (including the carcinoembryonic antigen and tissue polypeptide antigen serum levels) and the results of a complex staging workup were prospectively recorded. Receiver-operating characteristic curves and diagnostic formulas were used for data analysis. RESULTS Computed tomography of the thorax, upper part of the abdomen, and brain was the most accurate preoperative method to assess tumor resectability (receiver-operating characteristic area: 0.76, 95% confidence intervals: 0.67-0.86, P =.000; accuracy rate: 77%, confidence intervals: 69%-84%). Tissue polypeptide antigen was also predictive for tumor resectability (receiver-operating characteristic area: 0.62, 95% confidence intervals: 0.51-0.73, P =.035; accuracy rate at a threshold level of 110 U/L: 65%, 95% confidence intervals: 56%-73%). Carcinoembryonic antigen was diagnostic only at the extreme values of its distribution (accuracy rate at a level up to 10 ng/mL: 69%, 95% confidence intervals: 60%-77%). The probability of finding resectable disease at the time of the operation increased from 78% (baseline computed tomography-based probability) to 83% when the concentration of tissue polypeptide antigen was lower than 90 U/L and to 85% when the concentration of carcinoembryonic antigen was below 10 ng/mL. The probability of discovering an advanced disease increased from 68% (baseline computed tomography-based probability) to 89% when tissue polypeptide antigen levels were abnormal and to 100% when carcinoembryonic antigen concentrations were higher than 10 ng/mL. Conversely, the predictability of computed tomography was diminished by contrasting biomarker results, requiring further clinical investigations. CONCLUSIONS Computed tomography remains the gold standard for the preoperative evaluation of non-small cell lung cancer, although it may significantly underestimate the real tumor extension. The addition of the easy and inexpensive tissue polypeptide antigen test (with or without carcinoembryonic antigen) is capable of correcting this underestimation and helps to decide whether to completely rely on computed tomography or order additional clinical investigations.

Abstract
BACKGROUND Biomarkers of non-neuron-endocrine origin are measured only occasionally in the sera of patients with small-cell lung cancer (SCLC). An exception to this rule is carcinoembryonic antigen (CEA), for which, however, there is no consistent evidence. Based on such a premise, we decided to review the Cuneo Lung Cancer Study Group 16-year-experience with non-neuron-endocrine markers in SCLC. METHODS a total of 619 CEA, 621 tissue polypeptide antigen (TPA), and 616 lactate dehydrogenase (LDH) serum assays were obtained from 160 consecutive SCLC at diagnosis, during, and after treatment. Demographic, clinical, laboratory, and tumoral correlates were also available for another 25 pretreatment and 14 posttreatment variables. RESULTS bivariate correlation analyses showed that LDH and TPA were significantly related to each other, and both of them were also correlated with disease extent, and treatment response. LDH correlation indexes were higher than that of TPA, especially those regarding the parameters of disease extent. CEA was correlated only with the category of treatment response. Receiver-operating characteristic (ROC) analysis confirmed the correlation between stage disease at diagnosis and both LDH (P = 0.000) and TPA (P = 0.002), while the treatment failure was better recognized by TPA (P = 0.000). In univariate analysis, both LDH and TPA were correlated with survival (P = 0.000 and 0.092, respectively); however, only LDH remained significant in multivariate analysis (P = 0.012). CONCLUSIONS the evidence from this study does not suggest a routine CEA test in SCLC. LDH remains particularly useful and it should be kept in use. Finally, data on TPA is insufficient to advocate its systematic use in this type of malignancy.

Abstract
BACKGROUND Serum neuron specific enolase (NSE) is the most sensitive tumor marker of small cell lung carcinoma (SCLC) at diagnosis. Its prognostic value is still debated. Thus, the authors decided to assess the predictive value, in terms of complete response and survival, of serum NSE measured before and after one cycle of chemotherapy in patients with SCLC. METHODS Sera from 135 patients with histologically proven limited (n = 63) or metastatic (n = 72) SCLC were obtained. Clinical and biologic parameters with a known or suspected prognostic relevance were reviewed. Serum NSE was measured before chemotherapy (D1-NSE) and 28 days after its initiation (D28-NSE). The prognostic value of the parameters under study was evaluated in univariate and multivariate analyses using the Cox proportional hazards model and logistic regression analysis. RESULTS The level of serum NSE was raised in 120 patients (88%) prior to therapy. The probability of a normal D28-NSE value was not affected by the baseline D1-NSE value. Disease extension (P = 0.0005), performance status (P = 0.0001), D28-NSE (P = 0.003), and carcinoembryonic antigen (CEA) levels (P = 0.008) were found to be predictive for survival, whereas age, gender, plasma sodium, serum protides, and D1-NSE were not. Median survival and 2-year overall survival were 15.3 months and 21% (95% confidence interval [CI], 13-31%) when D28-NSE was normal and 8.1 months and 15% (95% CI, 8-27%) when it was not (P < 0.03). Only performance status (P = 0.001), disease extension (P = 0.002), and D28-NSE (P = 0.02) were found to be independent prognostic parameters for survival in the multivariate analysis. A simple prognostic index was developed using these 3 variables. Limited disease, a normal D28-NSE value, and a normal CEA value prior to therapy were the only parameters predictive for complete response in the univariate analysis, and D28-NSE (P = 0.01) and disease extension (P = 0.0001) were found to be independent variables in multivariate analysis. A complete response to therapy occurred in 62% with a normal D28-NSE value and in only 34% in the opposite case. CONCLUSIONS Normal serum D28-NSE is a strong, independent early predictor of both complete response to therapy and survival. This simple tool may be proposed for use in the clinic and in research, in association with an assessment of disease extension and performance status, to predict the outcome of patients with SCLC.

Abstract
Establishment of a simple biochemical index for diagnosis of cancer and management of patients with neoplastic diseases remains one of the important goals to be achieved in cancer research. The current investigation determined serum levels of carcinoembryonic antigen (CEA), total sialic acid (TSA) and lipid bound sialic acid (LSA) in 192 untreated lung cancer patients and compared with 80 age- and sex-matched controls (44 non-smokers and 36 smokers). The levels of all the markers were significantly elevated (P < 0.001) in lung cancer patients compared to the controls. CEA and LSA values were significantly raised (P < 0.001 and P < 0.01, respectively) in smokers compared to non-smokers. TSA and LSA values were more sensitive than CEA for diagnosis of lung cancer. Mean values of the three markers were higher in non-responders (n = 5) compared to the responders (n = 10). The results suggest that along with CEA, TSA and LSA might be included as routine parameters in lung cancer patients.

Abstract
Multivariate models of survival have been established for both small cell and non-small cell lung cancers. So far, no study has focussed on squamous cell types. Previous demonstrations of the prognostic value of the tissue polypeptide antigen (TPA) and, partially, of the carcinoembryonic antigen (CEA) are based on univariate analyses of survival. These analyses do not account for the other prognostic factors. In the present study, we report the combined influence of various clinical and biological characteristics on the survival duration of 360 patients with a newly diagnosed squamous cell carcinoma of the lung. The study comprised 29 variables, including age, sex, smoking habit (SH), symptoms at diagnosis, the Karnofsky performance status (KPS), weight loss (WL), radiological findings, various disease extent parameters (DEP), CEA and TPA. Preliminary univariate analyses showed that 20 variables were survival-related. The Cox proportional hazards regression analysis selected stage of disease, KPS, TPA, WL, the existence of bone metastases, and SH as independent factors of prognosis (global chi-square: 122.40, P = 0.0000). A second multivariate analysis, performed with the same covariates but excluding DEP, revealed previous pulmonary diseases and CEA to be, in addition to KPS, TPA, SH, and WL the next most influential prognostic determinants. Also in squamous cell lung cancer, classifications based on the Cox's prediction equation may improve individual counseling and patient selection for therapeutic trials. In this malignancy, TPA shows an independent and strong prognostic significance while CEA shares informations of diverse other prognostic factors and seems to be less important.

Abstract
Levels of the tumour markers neurone specific enolase (NSE), lactate dehydrogenase (LDH), chromogranin A (ChrA) and carcinoembryonic antigen (CEA) were measured in serum taken at presentation and during treatment, remission and relapse from 154 patients who received chemotherapy for small cell lung cancer at a single centre over a 6 year period. At presentation NSE was the most frequently elevated marker, being raised in 81% of patients and significantly higher in extensive as opposed to limited disease, as were LDH and ChrA. The response rate to therapy was best correlated with presentation level of ChrA, being 79% for those whose levels were within twice the upper limit of normal and 51% above (P < 0.01). Multivariate regression analysis showed NSE, performance status and albumin at presentation to be the best independent predictors of survival. Patients with NSE below twice the upper limit of normal, Karnofsky performance status of 80 or above and albumin 35 g l-1 or above had a median survival of 15 months with 25% alive at 2 years, whilst those with NSE above twice normal, Karnofsky below 80 and albumin less that 35 g l-1 had all died by 8 months. Changes in marker levels during therapy were of low predictive value for outcome although the finding of rising NSE during chemotherapy after an initial fall correlated with significantly reduced duration of remission. There was a strong inverse correlation between the NSE level at the time of response and duration of remission (P < 0.0001). Prediction of relapse was most reliable with ChrA, 52% of patients having rising levels before clinical evidence of disease recurrence.

Abstract
An immunohistochemical study has been carried out on fibre optic-biopsy specimens from patients with small cell lung cancer (SCLC) who had either died within 3 months, or who had survived more than 2 years. Long term survivors (LTS) were identified from completed clinical trials at major UK centres and were matched for age and sex within the trial with short term survivors (STS). The panel of immunohistochemical markers included those previously reported to be associated with prognosis, and reagents representative of both neuroendocrine and epithelial differentiation. A preliminary screen of 17 antibodies identified 11 as consistently reactive on paraffin-embedded material using streptavadin-biotin immunoperoxidase. Of 186 identified patients, 110 biopsy samples were retrieved. Of these, 70 gave sufficient material for analysis. All sections were scored by three observers without knowledge of the prognosis. The analysis failed to identify any antigen whose expression was correlated with prognosis. We conclude that, in fibre-optic biopsy specimens, immunohistochemical analysis does not add prognostic information in SCLC.

Abstract
The recovery of neoplastic cells by bronchoalveolar lavage is useful in the diagnosis of lung cancer. Abnormal epithelial cells can also be recovered from patients with interstitial lung diseases who do not have cancer, and therefore the usefulness of lavage in the diagnosis of malignancy in this setting is unknown. In this study, we evaluated the diagnostic significance of abnormal lavage cells recovered from patients with diffuse parenchymal abnormalities and compared the usefulness of standard cytologic assessment, correlation with clinical features, and immunocytochemical staining for carcinoembryonic antigen (CEA) in identifying abnormal cells that are truly malignant. Thirty of 2,314 patients had atypical lavage cells, but in only nine was lung cancer demonstrated. Although most patients with clinical suspicion of malignancy had lung carcinoma (six of seven), one such patient did not have cancer, and three were shown to have unsuspected carcinoma. Cytologic criteria identified definitely malignant cells in only four of nine patients with lung cancer, indicating that the approach is not sensitive. Immunostaining of abnormal cells with anti-CEA antibodies proved helpful. All patients with lung malignancy had CEA+ cells (n = 9), and no patient whose abnormal cells were CEA- proved to have cancer (n = 17). Because only nine of 13 patients with CEA+ cells had lung malignancy, the test is not diagnostic, but it appears to limit the need for further evaluation to a smaller group of patients in whom cancer is likely to be present. When used together, cytopathologic findings, detection of CEA by immunocytochemical techniques, and clinical correlates proved useful in diagnosis of lung malignancy, but further improvements are still needed to improve diagnostic accuracy.
