Abstract
BACKGROUND It is difficult to predict gene mutations individually based on clinical background alone. Tumor markers may help to predict each gene mutation. Identifying tumor markers that can predict gene mutation will facilitate timely genetic testing and intervention. METHODS We selected 134 cases of advanced or recurrent ALK-positive and 172 cases of advanced or recurrent EGFR-positive lung cancer from our clinical database. The cutoff values for the tumor markers were defined as 5.0 ng/mL or higher for carcinoembryonic antigen (CEA) and 3.5 ng/mL or higher for soluble fragment of cytokeratin 19 (CYFRA21-1) in accordance with the institutional standards. A positive CYFRA21-1:CEA ratio was defined as 0.7 or higher. RESULTS The CEA-positivity rate was 49% for ALK-positive lung cancers and 73% for EGFR-positive lung cancers, which was significantly different (p < 0.001). The CYFRA21-1 positivity rate was significantly higher in ALK-positive lung cancer (36%) compared with EGFR-positive lung cancer (23%) (p = 0.034). The median CYFRA21-1:CEA ratio was 0.395 for the ALK group, which was significantly higher compared with 0.098 for the EGFR group (p < 0.001). These trends were similar when excluding histology other than adenocarcinoma. The median time-to-treatment failure (TTF) for initial tyrosine kinase inhibitor (TKI) therapy was 308 days for the high CYFRA21-1:CEA ratio group and 617 days for the low CYFRA21-1:CEA ratio group for ALK-positive lung cancer (p = 0.100). CONCLUSIONS A higher proportion of patients with ALK-positive lung cancer were CYFRA21-1 positive and had higher CYFRA21-1:CEA ratios compared with EGFR-positive lung cancer patients.

Abstract
Lung cancer is the leading cause of cancer-related mortality in Japan and worldwide. Early detection of lung cancer is an important strategy for decreasing mortality. Advances in diagnostic imaging have made it possible to detect lung cancer at an early stage in medical practice. Conversely, screening of asymptomatic healthy populations is recommended only when the evidence shows the benefits of regular intervention. Due to a variety of evidence and racial differences, screening methods vary from country to country. This article focused on the perspective of lung cancer screening in Japan.

Abstract
PURPOSE Less-invasive early diagnosis of lung cancer is essential for improving patient survival rates. The purpose of this study is to demonstrate that serum comprehensive miRNA profile is high sensitive biomarker to early-stage lung cancer in direct comparison to the conventional blood biomarker using next-generation sequencing (NGS) technology combined with automated machine learning (AutoML). METHODS We first evaluated the reproducibility of our measurement system using Pearson's correlation coefficients between samples derived from a single pooled RNA sample. To generate comprehensive miRNA profile, we performed NGS analysis of miRNAs in 262 serum samples. Among the discovery set (57 patients with lung cancer and 57 healthy controls), 1123 miRNA-based diagnostic models for lung cancer detection were constructed and screened using AutoML technology. The diagnostic faculty of the best performance model was evaluated by inspecting the validation samples (74 patients with lung cancer and 74 healthy controls). RESULTS The Pearson's correlation coefficients between samples derived from the pooled RNA sample ≥ 0.98. In the validation analysis, the best model showed a high AUC score (0.98) and a high sensitivity for early stage lung cancer (85.7%, n = 28). Furthermore, in comparison to carcinoembryonic antigen (CEA), a conventional blood biomarker for adenocarcinoma, the miRNA-based model showed higher sensitivity for early-stage lung adenocarcinoma (CEA, 27.8%, n = 18; miRNA-based model, 77.8%, n = 18). CONCLUSION The miRNA-based diagnostic model showed a high sensitivity for lung cancer, including early-stage disease. Our study provides the experimental evidence that serum comprehensive miRNA profile can be a highly sensitive blood biomarker for early-stage lung cancer.

Abstract
BACKGROUND AND OBJECTIVES To construct a prediction model of solitary pulmonary nodules (SPNs), to predict the possibility of malignant SPNs in patients aged 15-85 years in northwest China for clinical diagnostic and therapeutic decision-making. METHODS The features of SPNs were assessed by multivariate logistic regression, followed by visualization using a nomogram. Hosmer lemeshow was applied to evaluate the fitting degree of the model. The area under the receiver operating characteristic (ROC) curve was identified to determine the discriminative ability of the model. RESULTS Lobulation, spiculation, pleural-tag, carcinoembryonic antigen, neuron-specific enolase, and total serum protein were independent predictors of malignant pulmonary nodules (p < .05). Lobulation (100 points) scored the highest in the nomogram, and the Hosmer-Lemeshow goodness-of-fit statistic was 0.805 (p > .05). The area under curve (AUC) of the modeling and validation groups using logistic regression were 0.859 (95% CI, 0.805-0.903) and 0.823 (95% CI, 0.738-0.890), respectively. Moreover, the AUC of our model was higher than that of the Mayo model, VA model, and Peking University (AUC 0.823 vs. 0.655 vs. 0.603 vs. 0.521). CONCLUSION Our prediction model is more suitable for predicting the possibility of malignant SPNs in northwest China, and can be calculated using a nomogram to determine further treatments.

Abstract
RATIONALE AND OBJECTIVES The study aimed to assess the relationship between tumor marker index (TMI) and high-resolution computed tomography features in early-stage lung adenocarcinoma. MATERIALS AND METHODS Seventy-four stage IA lung adenocarcinomas confirmed pathologically were retrospectively evaluated. Lung nodules were divided into two types: solid nodule (SN) and subsolid nodule (SSN). The maximum diameters on mediastinal window in axial imaging (Dm) and tumor shadow disappearance rate (TDR) were measured. Meanwhile, other computed tomography features of lung nodules were also recorded. TMI represents the geometric mean of normalized CEA and CYFRA 21-1 values, and the discriminatory value of TMI in this study was set at 1.0. The evaluation of discriminatory values for Dm and the TMI between SNs and SSNs was done with Mann-Whitney U-test. The relationship between TDR and TMI in SSNs was evaluated by Pearson correlation analysis. RESULTS Of 74 cases, 40 cases (54.05%) showed SNs and 34 cases (45.95%) showed SSNs. Dm and TMI were higher in SNs than in SSNs (z = -4.782, P < 0.001; z = -2.647, P = 0.008). TDR demonstrated negative relationship with TMI in SSNs (r = -0.448, P = 0.008). Spiculation (odds ratio [OR] = 14.685; 95% confidence interval [CI]: 2.739-78.729; P = 0.002), nodule type (OR = 6.215; 95% CI: 1.531-25.228; P = 0.011), and gender (OR = 0.227; 95% CI: 0.062-0.833; P = 0.025) were independent factors associated with TMI. CONCLUSIONS Early-stage lung adenocarcinoma with lower TDR coexisting with spiculation was associated with higher TMI, especially in patients with solid nodule, which tended to have poor prognosis.

Abstract
BACKGROUND The aim of this retrospective study was to assess the prognostic value of serum tumor markers (carcinoembryonic antigen (CEA) and CYFRA21-1) in patients with pathologic (p-) stage I non-small cell lung cancer (NSCLC) undergoing complete resection. METHODS Two hundred and seventy-five patients (163 males, 112 females, mean age 67.1 years) with p-stage I NSCLC who underwent complete resection at our institution between April 1999 and October 2004 were examined. Patients who had received preoperative chemotherapy or radiotherapy were excluded, as were patients who had multiple malignancies including multiple lung cancer. The serum levels of tumor markers were measured using commercially available immunoassays within 1 month before surgical resection. Serum levels of CEA and CYFRA21-1 higher than 5.0 and 2.8 ng/ml, respectively, were considered as positive according to the manufacture's instructions. RESULTS The histological classification was adenocarcinoma in 193 patients, squamous cell carcinoma in 71, large cell carcinoma in 5, and other histological type in 6. One hundred and fifty-seven patients had T1 disease and 118 patients had T2 disease. The positive ratio of CEA and CYFRA21-1 was 25.7% and 13.7%, respectively, and in relation to histological type was 27.8% and 7.8% in adenocarcinoma, and 20.6% and 28.4% in squamous cell carcinoma. The overall 5-year survival rate was 79.3%. With a median follow-up of 35.5 month for surviving patients, those with initial CYFRA21-1 serum levels higher than 2.8 ng/ml had a significantly worse prognosis (p=0.0041). Patients with an elevated preoperative CEA level exceeding 5.0 ng/ml had a shorter disease-free survival period (p=0.0003). In patients with adenocarcinoma, a CEA level above 5.0 ng/ml was associated with shorter survival and early recurrence, whereas CYFRA21-1 showed no such association. In patients with squamous cell carcinoma, elevated preoperative CEA was not related to survival and recurrence. In these patients, preoperative CYFRA21-1 level exceeding 2.8 ng/ml was associated with a poorer outcome, whereas preoperative CYFRA21-1 level was not associated with cancer recurrence. CONCLUSION The patients with p-stage I adenocarcinoma whose preoperative CEA level was high might be considered as good candidates for adjuvant chemotherapy. The prognostic value of CYFRA21-1 could not be confirmed for stage I NSCLC, and preoperative CYFRA21-1 level was not useful in selecting the candidates for adjuvant chemotherapy.

Abstract
The expression of biomarkers by lung cancers is useful in the diagnosis and clinical management of patients with lung cancer. Biomarkers provide insight into histogenesis, interrelationships, and biological behavior of lung tumors. This chapter presents data on lung cancer detection, involving some of the most studied and interesting lung cancer biomarkers to date-CYFRA 21-1, NSE, ProGRP, SCC, CEA, Tumor M2-PK, as well as markers in clinical application such as CRP, LDH, tumor-suppressor genes and oncogenes, CA125, CgA, NCAM, and TPA. Biomarker profiles in combination with fuzzy logic techniques have also been addressed. Serum markers used alone or in combination with other indices might play an important role in monitoring response to therapy in early detection of tumor reactivation in new treatment strategies as well as in secondary prevention.

Abstract
Antibodies to cytokeratin (CK) are found in some patients with autoimmune hepatitis (AIH). We hypothesized that serum antibodies to CK8, CK18 and CK19 may be formed in patients with AIH. We established an enzyme-linked immunosorbent assay (ELISA) to quantify anti-CK8, anti-CK18 and anti-CK19 antibodies in sera of patients with AIH. In addition, we quantified circulating CK8:anti-CK8 antibody as well as CK18:anti-CK18 antibody immune complexes in patients' sera, by an enzyme-linked immunosorbent assay (ELISA). Furthermore, to evaluate the expression of CK8, CK18 and CK19 in liver tissue, immunohistochemical stainings were performed. Significantly high levels of anti-CK8, anti-CK18 and anti-CK19 antibodies were demonstrated in patients with AIH compared with normal volunteers and patients with chronic active hepatitis C (CH-C). In addition, these antibodies were significantly decreased after steroid treatment. Levels of CK8:anti-CK8 and CK18:anti-CK18 immune complexes in sera of patients with AIH were significantly high compared with those of patients with CH-C and normal volunteers. Immunohistochemically, CK8 or CK18 were absent from some hepatocytes of AIH. CK19 was aberrantly expressed in periportal hepatocytes in patients with AIH, but not CH-C. This is the first study to quantify anti-CK8, anti-CK18, anti-CK19 antibodies and immune complexes in patients with AIH. The clinical significance of anti-CK antibodies and their immune complexes of AIH is also discussed.

Abstract
To elevate the diagnostic value of the serum cytokeratin 19 fragment (CYFRA 21-1) and compare it with carcinoembryonic antigen (CEA) and tissue polypeptide antigen (TPA) in bronchogenic carcinoma, the sera of 161 patients (58 with benign pulmonary disease and 103 with bronchogenic carcinoma) was investigated using immunoradiometric assay. Sensitivities for CYFRA 21-1, CEA and TPA (using 3.5 ng ml-1, 5.0 ng ml-1, 110 U l-1, respectively, cut-off values corresponding to a 95% specificity for benign pulmonary disease) in bronchogenic carcinoma were 64, 47 and 61%, respectively. Positive CYFRA 21-1 levels were identified in 75% of patients with squamous cell carcinoma (n = 36), in 67% with adenocarcinoma (n = 45), in 17% with large cell carcinoma (n = 6), and in 50% with small cell lung cancer (SCLC) (n = 16). However, CYFRA 21-1 levels were not significantly different between squamous cell carcinoma and the other histological types. The sensitivity of the combined measurement of CYFRA 21-1 with any other tumour marker was significantly higher than that of CYFRA 21-1 measurement alone. Elevated CYFRA 21-1 levels were observed in 44% of Stages I and II (n = 18) and 72% of Stage III and IV (n = 69) patients with non-small cell lung cancer (P < 0.05). A significant inter-marker correlation was observed between CYFRA 21-1 and TPA (n = 103, r = 0.448, P < 0.0001). Twenty-one patients were monitored by CYFRA 21-1, and significantly different changes in progressive patients (P = 0.0058) and regressive patients (P = 0.016) were obtained. These results indicate that CYFRA 21-1 may be not only a sensitive tumour marker in the diagnosis of bronchogenic carcinoma, but also a useful marker for the monitoring of bronchogenic carcinoma.
