[PMID: 31122008 PMCID: PMC6962475 DOI: 10.4143/crt.2019.007] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2019] [Accepted: 05/16/2019] [Indexed: 12/16/2022] Open
Abstract
Purpose Fluorodeoxyglucose positron emission tomography–computed tomography (PET-CT) is gaining evidence as a predictive factor in non-small cell lung cancer (NSCLC). Stereotactic ablative radiotherapy (SABR) is the standard treatment in early-stage NSCLC when a patient is unsuitable for surgery. We performed a study to assess the prognostic clinical significance of PET-CT after SABR in early-stage NSCLC. Materials and Methods Seventy-six patients with stage I NSCLC treated with SABR were investigated. Total radiation dose ranged from 36 to 63 Gy in three to eight fractions depending on tumor location and size. Respiratory motion control was implemented at simulation and during treatment. PET-CT prior to SABR was performed in 66 patients (86.8%). Results Median follow-up time was 32 months (range, 5 to 142 months). Local control rate at 1, 2, and 5 years were 95.9%, 92.8%, and 86.7%, respectively. Overall survival (OS) at 1, 2, and 5 years were 91.0%, 71.3%, and 52.1% respectively. Cause-specific survival at 1, 2, and 5 years were 98.6%, 93.1%, and 84.3% respectively. Tumor size and pre-SABR maximal standardized uptake value (SUVmax) demonstrated statistical significance in the Kaplan-Meier survival analyses with log-rank test. In multivariate analyses pre-SABR SUVmax remained statistically significant in correlation to OS (p=0.024; hazard ratio [HR], 3.2; 95% confidence interval [CI], 1.2 to 8.8) and with marginal significance in regards to regional progression-free survival (p=0.059; HR, 32.5; 95% CI, 2.6 to 402.5). Conclusion Pre-SABR SUVmax demonstrated a predictive power in statistical analyses. Tumors with SUVmax above 6 at diagnosis were associated with inferior outcomes.

Abstract
In early stage non-small cell lung cancer (NSCLC) large randomized trials have demonstrated that in patients with radically resected disease adjuvant chemotherapy improves 5-year survival rates. However, a customization of systemic treatment is needed to avoid treatments in patients cured by surgery alone or to justify the use of adjuvant chemotherapy in high risk patients, including those in stage IA. Recently, the possibility of identifying prognostic and predictive factors related to the genetic signatures of the tumor that could affect adjuvant and neo-adjuvant treatment choices for resectable non-small cell lung cancer (NSCLC) has been of interest. This review summarizes the current status and future opportunities for clinical application of genotyping and genomic tests in early NSCLC.

Abstract
A greater understanding of non-small-cell lung cancer at a molecular level has led to the identification of an increasing number of driver mutations. Extensive research of the KRAS gene as well as specific mutations has established its role in tumorigenesis. Nevertheless, the role of KRAS oncogene in non-small-cell lung cancer remains unclear. Recent studies indicated that mutant KRAS could be predictive of lack of response to chemotherapy, but large pooled analysis failed to confirm this result. The predictive value of KRAS mutation and EGFR-TKI treatment is more ambiguous with some recent evidence suggesting that it may be a negative predictive biomarker. This review provides an overview of RAS biology, assesses the utility of KRAS as a prognostic marker, and evaluates its role as a predictive marker for response to chemotherapy and EGFR-TKIs. In addition, we review some current studies that are targeting the KRAS pathway.

Abstract
Purpose To determine whether the maximum standardized uptake value (SUV) of [18F] fluorodeoxyglucose uptake by positron emission tomography (FDG PET) ratio of lymph node to primary tumor (mSUVR) could be a prognostic factor for node positive non-small cell lung cancer (NSCLC) patients treated with definitive radiotherapy (RT). Materials and Methods A total of 68 NSCLC T1-4, N1-3, M0 patients underwent FDG PET before RT. Optimal cutoff values of mSUVR were chosen based on overall survival (OS). Independent prognosticators were identified by Cox regression analysis. Results The most significant cutoff value for mSUVR was 0.9 with respect to OS. Two-year OS was 17% for patients with mSUVR > 0.9 and 49% for those with mSUVR ≤ 0.9 (p = 0.01). In a multivariate analysis, including age, performance status, stage, use of chemotherapy, and mSUVR, only performance status (p = 0.05) and mSUVR > 0.9 (p = 0.05) were significant predictors of OS. Two-year OS for patients with both good performance (Eastern Cooperative Oncology Group [ECOG] ≤ 1) and mSUVR ≤ 0.9 was significantly better than that for patients with either poor performance (ECOG > 1) or mSUVR > 0.9, 23% (71% vs. 23%, p = 0.04). Conclusion Our results suggested that the mSUVR was a strong prognostic factor among patients with lymph node positive NSCLC following RT. Addition of mSUVR to performance status identifies a subgroup at highest risk for death after RT.

Abstract
T-cell immunoglobulin- and mucin domain-3-containing molecule 3 (TIM-3) is a membrane protein expressed in various kinds of immune cells and plays a pivotal role in immune regulation. Recently, TIM-3 was reported to be expressed aberrantly in melanoma cells, contributing to the low adhesion ability of tumor cells and promoting the survival of melanoma cells. We investigated TIM-3 expression in non-small cell lung cancers (NSCLCs), and further analyzed whether the aberrant expression of TIM-3 is related to the prognosis for patients with lung cancer. Tumor tissue samples from 30 patients with NSCLC were involved. Results of immunohistochemical analysis showed that TIM-3 stained positive on tumor cells in 86.7% (26/30) patients with primary NSCLC. The TIM-3 expression in NSCLC tumor cells was correlated with histologic type and pathologic T classification of the disease (P < .05). More importantly, patients with TIM-3-positive tumor cells had a significantly shorter survival time than those with TIM-3-negative tumors. Multivariate analysis demonstrated the significant role of TIM-3 expression in tumor cells as an independent prognostic factor for patients with NSCLC (relative risk, 4.481; 95% confidence interval, 1.790-11.22; P = .0005). Our results suggest that the ectopic expression of TIM-3 in tumor cells may be a potential, independent prognostic factor for patients with NSCLC.

Abstract
The purpose of this study was to evaluate the prognostic value of L-type amino acid transporter 1 (LAT1) and 4F2 heavy chain (CD98) expression in patients with stage III non-small cell lung cancer (NSCLC). A total of 188 consecutive patients with pathologic stage III NSCLC were retrospectively reviewed. The expression of LAT1, CD98, Ki-67 labeling index, vascular endothelial growth factor (VEGF) as well as microvessel density (MVD) were evaluated immunohistochemically and correlated with the prognosis of patients after complete resection of the tumor. Positive expression of LAT1 and CD98 was noted in 58% (109/188) and 50% (94/188) of the cases, respectively (p=0.1473). A positive rate of LAT1 expression was significantly higher in squamous cell carcinoma (SQC) (90%, 48/53) and large-cell carcinoma (LCC) (100%, 12/12) than in adenocarcinoma (AC) (40%, 49/123). Moreover, a positive rate of LAT1 with CD98 expression was also significantly higher in SQC (74%, 39/53) and LCC (75%, 9/12) than AC (34%, 42/123). LAT1 expression was significantly higher in patients with mediastinal lymph node metastases than in patients without, and was significantly correlated with CD98, Ki-67 labeling index, VEGF and MVD. The 5-year survival rates of LAT1-positive and -negative patients and CD98-positive and -negative patients were 27.9 and 40.6% (p=0.0033), respectively, and 24.1 and 43.6% (p=0.0004), respectively. Multivariate analysis confirmed that positive expression of LAT1 and CD98 was an independent factor predicting a poor prognosis. In conclusion, the overexpression of LAT1 and CD98 is a pathological factor for predicting the prognosis of patients with surgically resectable stage III NSCLC.

Abstract
BACKGROUND The purpose of this study was to evaluate the prognostic value of L-type amino acid transporter 1 (LAT1) and 4F2 heavy chain (CD98) expression in resectable non-small-cell lung cancer (NSCLC) patients with N1 and N2 nodal involvement. METHODS A total of 220 consecutive patients were retrospectively reviewed. Immunohistochemical expression of LAT1, CD98, Ki-67 labeling index, vascular endothelial growth factor (VEGF), and microvessel density (MVD) was correlated with clinical features and prognosis of patients after complete resection of the tumor. RESULTS Positive expression of LAT1 and CD98 was recognized in 60% (132/220) and 47% (103/220), respectively (P = 0.021). A positive rate of LAT1 expression was significantly higher in squamous cell carcinoma (SQC) (91%; 65/71) and large cell carcinoma (LCC) (82%; 9/11) than in adenocarcinoma (AC) (42%; 58/138). Moreover, a positive rate of CD98 expression was also significantly higher in SQC (76%; 54/71) and LCC (73%; 8/11) than in AC (30%; 42/138). LAT1 expression was significantly correlated with CD98, Ki-67 labeling index, VEGF, and MVD. The 5-year survival rates of LAT1-positive and LAT1-negative patients and CD98-positive and CD98-negative patients, were 43% and 48% (P = 0.1043), respectively and 39% and 50% (P = 0.0239), respectively. Multivariate analysis confirmed that positive expression of CD98 was an independent factor for predicting a poor prognosis. CONCLUSIONS In our limited series, CD98 is a pathological factor that predicts prognosis in resectable adenocarcinoma patients with N2 disease.

Abstract
BACKGROUND In this study, we sought to evaluate the prognostic importance of chromosomal instability (CIN) in adenocarcinoma (AC) of the lung. The relationship between CIN detected by fluorescence in situ hybridization (FISH) and survival in AC patients was examined. METHODS Sixty-three surgical specimens of lung AC were analyzed. To identify tumors with CIN, p16 and multi-target DNA FISH assays for c-myc, chromosome 6, EGFR, and chromosome 5 (LAVysion, Vysis) were performed on nuclei extracted from paraffin-embedded tumor tissues. Survival rates were compared in terms of sex, age, histology, T factor, N factor, CIN, and smoking status. A sample was classified as CIN-positive if at least three of the five chromosomes were positive. RESULTS Out of the 63 specimens, 32 (39.7%) were CIN-positive. The 5-year overall disease-free survival rate was 58.7% as a whole, 46.9% for CIN-positive patients and 71.0% for the CIN-negative patients [hazard ratio (HR), 2.34; 95% confidence interval (CI), 1.04-5.26; p = 0.04]. The 5-year overall survival rate was 81.0%, 68.7% for CIN-positive patients and 93.5% for the CIN-negative patients (HR, 5.64; 95% CI, 1.23-25.70; p = 0.026). In multivariate analysis after adjusting for pathologic nodal staging, tumor staging, sex, age, and smoking history, compared with the CIN-negative patients, the CIN-positive status remained significantly associated with decreased overall survival (HR, 8.48; 95% CI, 1.66-43.42; p = 0.010). CONCLUSIONS CIN can be effectively detected in primary AC of lung using FISH analysis. CIN is associated with poor prognosis for AC, and may thus be utilized as an independent prognostic factor for the disease.

Abstract
New biological factors have not been extensively studied in stage III NSCLC as yet. The aim of this retrospective study was to assess the association between the expression and the prognostic role on survival of four biological markers in stage III NSCLC. Clinical characteristics were retrieved from the patients charts. EGF-R, Mdm2, p53 and TTF-1 expressions were evaluated by immunohistochemistry by three independent observers. Cox multivariate model was used to assess the impact of clinical and biological factors on patients' survival. A total of 84 stage III NSCLC patients, treated between 03/1987 and 08/2003, were included in the study. There was a statistically significant association between the expression of TTF-1 and EGFR (p=0.01) or TTF-1 and Mdm2 (p=0.04). Positive expressions for EGFR or TTF-1 were almost mutually exclusive. The status EGFR+/TTF-1--was mainly found in squamous cell carcinoma (18 among 19tumours). In multivariate analysis, only treatment with curative intent was independently associated with better survival (p=0.0004). In stage III NSCLC, there was a significant association between TTF-1 and EGFR or TTF-1 and Mdm2. The status EGFR+/TTF-1--was associated with squamous cell carcinoma.

Abstract
HYPOTHESIS The 2-[18F]-fluoro-2-deoxy-d-glucose positron emission tomography is an imaging tool for assessing clinical tumor, node, metastasis in non-small cell lung cancer (NSCLC). Primary tumor standardized uptake value (SUV) has been studied as a potential prognostic factor for survival. However, the sample sizes are limited leading to conduct a meta-analysis to improve the precision in estimating its effect. METHODS We performed a systematic literature search. For each publication, we extracted an estimate of the hazard ratio (HR) for comparing patients with a low and a high SUV and we aggregated the individual HRs into a combined HR, using a random-effects model. RESULTS We found 13 eligible studies dedicated to NSCLC. Most of them included patients with stages I to III/IV and used a SUV assessment corrected for body weight. Number of patients ranged from 38 to 315 (total: 1474); 11 studies identified a high SUV as a poor prognostic factor for survival although two studies found no significant correlation between SUV and survival. SUV measurement and SUV threshold for defining high SUV were study dependent, eight studies looked for a so-called best cutoff (maximizing the logrank test statistic) without adjusting the p value for multiplicity. Overall, the combined HR for the 13 reports was 2.27 (95% confidence interval [CI]: 1.70-3.02); excluding the studies proposing a "best" cutoff, it was 2.08 (95% CI: 1.431-3.04). CONCLUSION Our meta-analysis suggests that the primary tumor SUV measurement has a prognostic value in NSCLC; these results should be confirmed in a meta-analysis on individual patients' data.

Abstract
In a previous study, we demonstrated that human leucocyte antigen G (HLA-G) was aberrantly expressed in a majority of primary colorectal carcinomas, and that the detection of HLA-G expression had a strong and independent prognostic value in human colorectal cancer. In the current study, we look into whether the aberrant expression of HLA-G is also related to non-small cell lung cancer (NSCLC). The expression of HLA-G was investigated immunohistochemically in 106 patients with NSCLC. The correlation between HLA-G status and various clinicopathological parameters was analysed. As well, the level of HLA-G expression was also compared to the survival rate of patients with NSCLC. In total, we found that in 75% (79/106) of the primary site of NSCLC, an aberrant HLA-G expression was detected. However, this expression was not observed in the normal lung tissues. HLA-G expression in NSCLC was significantly correlated with lymph nodal metastasis, clinical stages of the disease, and host immune response (P = 0.0001, 0.0001, and 0.027, respectively). Patients with HLA-G positive tumours had a significantly shorter survival time than those with tumours that were HLA-G negative (P = 0.001). In addition, through multivariate analysis, HLA-G exhibited an independent prognostic factor (P = 0.01, relative risk 4.09; 95% confidence interval 1.40-11.9). All in all, our results indicate that the expression of HLA-G is a characteristic feature of NSCLC, and they suggest that immunostaining by anti-HLA-G antibodies may be a potentially useful prognostic indicator.

The aim of the present study was to determine the role of TTF-1 as prognostic factor in stage III NSCLC in addition to other known clinical factors. All stage III NSCLC patients treated in our hospital were retrieved and searched for biopsy specimens. TTF-1 was assessed by immunohistochemistry (Novocastra SPT24). Between 01/1987 and 07/2003, 108 assessable stage III NSCLC patients were included in the study. Their principal characteristics were: median age 64 years (range 37-83), male/female 81/27, squamous/non squamous 52/56, IIIA/IIIB 44/64, median Karnofsky PS 80 (range 20-100). Forty-four patients were positive for TTF-1 (squamous 25.0% versus non-squamous 55.4%). In multivariate analysis, only three factors were statistically significantly associated with better survival: good PS, surgery and creatinine level. CONCLUSION In stage III NSCLC patients, good PS, resectability and low creatinine level but not TTF-1 are prognostic factors for survival.

Abstract
BACKGROUND Reversion-inducing cysteine-rich protein with Kazal motifs (RECK) is a novel membrane-anchored matrix metalloproteinase inhibitor, and experimental studies have shown that RECK can suppress tumor progression through angiogenesis inhibition. We have already revealed that enhanced RECK expression is significantly correlated with a favorable prognosis in non-small-cell lung cancer (NSCLC). In this study, further analyses focused on pN2 disease were conducted to assess the clinical significance of RECK expression. METHODS A total of 118 patients with completely resected pathologic stage IIIA N2 NSCLC were retrospectively examined. RECK expression in the primary tumor, along with involved N2 nodes, was examined immunohistochemically. RESULTS RECK expression in the primary tumor was strong in 53 patients (44.9%) and was weak in the other 65 patients. The 5-year survival rate of patients with RECK-strong tumor (42.9%) was significantly higher than that of patients with RECK-weak tumor (23.1%; P = .017). Reduced RECK expression significantly correlated with a poor prognosis for patients with a single N2 node involved (P = .019), but not for patients with multiple N2 nodes involved (P = .440). A multivariate analysis confirmed that reduced RECK expression was an independent and significant factor to predict a poor prognosis (P = .031). RECK expression in involved N2 nodes was significantly higher than in primary tumors (P < .001). CONCLUSIONS RECK status was a novel prognostic factor in pathologic stage IIIA N2 NSCLC.

Abstract
PURPOSE To determine the prognostic value of dynamic MRI for non-small-cell lung cancer (NSCLC) patients after chemoradiotherapy. MATERIALS AND METHODS A total of 114 consecutive patients with NSCLC underwent dynamic MRI after chemoradiotherapy. The patients were divided into two groups (local control (n=22) and local failure (n=92)) according to the presence of local recurrence. From the signal intensity-time course curve in each subject, the maximum relative enhancement ratio and slope of enhancement were calculated, and compared between two groups by Student's t-test. To determine the feasible threshold values of both MR indexes for group differentiation, ROC-based positive tests were performed. Finally, the Kaplan-Meier survival curves of each group divided by the adapted threshold value were compared by log-rank test. RESULTS The maximum relative enhancement ratio and the slope of enhancement in the local control group were significantly lower than those in the local failure group (P<0.05). Using 0.08/sec as the threshold value of the slope of enhancement, the sensitivity and specificity for differentiation between the two groups were 90.9% and 91.3%, respectively. When the slope of enhancement was adopted for estimation of prognosis after therapy, the mean survival period of the slope of enhancement<or=0.08/sec group was significantly longer than that seen in the group with a slope of enhancement>0.08/sec (P<0.0001). CONCLUSION Dynamic MRI has potential prognostic value for NSCLC patients after chemoradiotherapy.

Abstract
Histological classification and staging are cornerstones of diagnosis in lung cancer. Treatment options have been enriched in the last few years by the development of a number of new drugs, and therapy is now increasingly being carried out within multimodal concepts and at earlier stages. Still, outcome of the disease is far from satisfactory and progress in clinical and preclinical research is time-consuming. With the whole variety of potent new therapeutic compounds including classical cytostatics and biological factors at hand, many now believe that a clear improvement of treatment results will be derived from a better understanding of the biology of these tumours and a resulting improvement of diagnosis. Biological factors reflecting the underlying tumour biology and aspects of clinically important pathomechanisms may not only better predict outcome of the disease but also of its treatment, serving as surrogate markers for a more appropriate general intensification of therapy and ideally for specific "targeted" interventions. This article describes the different insights in the biology of these tumours in relation with the representing surrogate markers, and opens routes to possible diagnostic and therapeutic consequences.

Abstract
UNLABELLED The 1997 International staging system (ISS) classification separated stage III non-small cell lung cancer (NSCLC) into stages IIIA and IIIB. In a previous study including unresectable NSCLC initially treated with chemotherapy, we analysed survival according to tumour (T) and node (N) stages and derived a classification into stages IIIbeta (T3-4N3) and IIIalpha (other TN stage III) that had a better discrimination on survival distribution. The aim of this study was to validate these results in a further set of patients. Patients with unresectable stage III NSCLC included in a phase III trial assessing the role of increased dose chemotherapy (SuperMIP: mitomycin 6 mg/m2, ifosfamide 4.5 g/m2, cisplatin 60 mg/m2, carboplatin 200 mg/m2) in comparison to standard chemotherapy MIP (mitomycin 6 mg/m2, ifosfamide 3 g/m2, cisplatin 50 mg/m2), before thoracic irradiation (60 Gy in 30 fractions over 6 weeks) were the subject of this study. Survival distributions were assessed by the method of Kaplan-Meier. Survival comparisons were made by the log-rank test. Multivariate analyses using Cox regression models, included all potential prognostic factors for survival with a P-value <0.2 in univariate analysis. According to the 1997 International staging system classification, 328 eligible patients were included in the study. There was no imbalance between the two arms. Five parameters were significantly associated (P < or = 0.05) with survival in univariate analysis: European lung cancer working party (ELCWP) staging (IIIalpha[n = 294 pts] versus IIIbeta [n = 46]), Karnofsky index, weight loss, platelet count and haemoglobin level. These variables as well as the 1997 ISS staging, white blood cell (WBC) count, LDH and sodium levels were included in a multivariate analysis. Two models were constructed, including either the ELCWP or the 1997 ISS. In model 1 (ISS included), Karnofsky index (HR 0.69; 95% confidence interval (CI) 0.47-1.00; P = 0.05) and haemoglobin (HR 1.49; 95% CI 1.11-1.99; P = 0.007) were found significant. In model 2, including ELCWP staging, two variables were associated with survival: ELCWP staging (HR 1.68; 95% CI 1.20-2.35; P = 0.002) and haemoglobin (HR 1.54; 95% CI 1.15-2.07; P = 0.01). CONCLUSION In initially unresectable stage III NSCLC treated by chemotherapy and radiotherapy, we validated the results of our previous study. The classification into stages IIIbeta (T3-4N3M0) and IIIalpha (other TN stage III) better discriminates the patients in term of survival than the 1997 ISS classification.

Abstract
Purpose To determine whether deleted in colon cancer (DCC) protein expression in colorectal cancer (CRC) metastases could predict outcome to palliative fluorouracil (FU)-based chemotherapy and to assess whether it is similar to that observed in the corresponding primary tumors. Patients and Methods DCC protein expression was assessed immunohistochemically on archival specimens of CRC metastases from 42 patients homogeneously treated by methotrexate-modulated bolus FU alternated to 6-S-leucovorin–modulated infused FU and was retrospectively correlated with patient characteristics and clinical outcome. In a subset analysis, DCC immunoreactivity was compared between metastatic CRC and the corresponding primary tumors and regional lymph node metastases. Results Positive immunoreactivity for DCC was found in 45% of patients. Eighteen (78%) of 23 patients for whom multiple samples were available displayed a similar pattern of expression in distant metastases and primary tumors. The median survival time was 14.3 months in patients without DCC expression and 21.4 months in patients with DCC-positive tumors (log-rank test, P = .04); the 2-year survival rates were 8.5% and 42.5%, respectively. Response rates to chemotherapy were not significantly different between the two groups. By multivariate analysis, DCC protein expression maintained its prognostic value and showed to be the single best predictor of survival, with a relative risk of 2.16. Conclusion Our results indicate that expression of the DCC protein in CRC metastases is similar to that observed in the corresponding primary tumors and represents a dominant predictor of survival in patients with unresectable, advanced CRC who are undergoing palliative FU-based chemotherapy.

Abstract
The aim of this study was to investigate the prognostic significance of a panel of biological parameters in patients with radically resected non-small cell lung cancers (NSCLC). 269 cases with pathological stage I-IIIA NSCLC were retrospectively analysed. Immunohistochemistry was performed to detect protein expression of p53, bcl-2, proliferating cell nuclear antigen (PCNA) and CD34. Polymerase chain reaction (PCR)/direct nucleotide sequencing method was used to detect mutations in K-ras (codons 12, 13, 61, exons 1-2). The Kaplan-Meier estimates of survival were calculated for clinical and biological variables using the Cox model for multivariate analysis. Histological subtype and the pathologic tumour extension (pT) were the most powerful clinical-pathological prognostic factors for survival (P=0.030 and P=0.031, respectively), whereas among the biological parameters, p53 overexpression (P=0.032) and K-ras mutation (P=0.078) had a negative prognostic role, as demonstrated by multivariate analysis. Conversely, bcl-2, PCNA and CD34 expression were not correlated with survival. Statistically significant associations between p53 expression and the squamous cell carcinoma (SCC) subtype, bcl-2 expression and SCC subtype, K-ras mutation and p53 negative expression, p53 and bcl-2, bcl-2 and PCNA overexpression were observed. In conclusion, some biological characteristics such as the K-ras and p53 status may provide useful prognostic information in resected NSCLC patients, in addition to the classical clinico-pathological parameters. However, further studies are needed to clarify the value of adopting biological prognostic factor into clinical practice.

Abstract
AIMS The aim of the study was assessment of the heterogeneity of stage IIIA non-small cell lung cancers (NSCLC) and the late results of surgical treatment. METHODS The study group consisted of 83 consecutive patients discharged between 1988 and 1992 undergoing radical operative treatment for stage IIIA NSCLC. Squamous cell carcinoma was diagnosed in 54 (65.1%) patients, adenocarcinoma in 23 (27.7%), large cell carcinoma in 2 (2.4%) and mixed (i.e. adenoid-squamous type) in 4 (4.8%). In respect of pTNM staging, 19 (22.9%) patients had T3N1M0, 35 (42.2%) had T2N2M0 and 29 (34.9%) had T3N2M0. RESULTS Overall, 13.3% of patients with stage IIIA NSCLC survived 5 years following the operation and 8.7% survived 10 years. Analysis of follow-up study indicated that this group was heterogenic. In T3N1M0 group 26.3% survived 5 years following the operation, in T2N2M0 group 14.3%, in T3N2M0 group 3.5% (P = 0.015). Of 23 patients with N2 disease and no metastases in hilar lymph nodes ('skip' metastases), 26.1% survived 5 years, whereas none of 41 patients with metastases spreading by continuity survived (P = 0.0015). If mediastinal lymph node metastases were diagnosed in one level, 25% patients survived 5 years, but if two or more levels were affected, 2.3% only (P = 0.0214): 85.7% of patients with well-differentiated (G1) cancer survived 5 years and 62.0% 10 years, whereas among those with moderately differentiated (G2) tumours, 11.8% and 8.8%, respectively. No patient survived 5 years after resection of poorly differentiated (G3) cancer (P < 0.001). CONCLUSIONS (1) Patients operated for stage IIIA NSCLC are a heterogeneous group, which makes it difficult to predict late results. (2) Patients operated for stage IIIA NSCLC have a better prognosis if metastases are discovered in level one mediastinal lymph nodes, particularly in the superior part of mediastinum, or if 'skip' metastases (pulmonary hilus unaffected) are discovered, as compared to those with N2 disease. (3) Poor histologic differentiation of the tumour is a bad prognostic factor.

Abstract
The last two decades have seen an exponential growth of our knowledge on the molecular biology of cellular processes and neoplastic transformation. There is high expectation that these advances will be translated into further improvement in the care of cancer patients, especially in the areas of prevention, diagnosis and treatment. Realizing that the histopathological classification of lung cancer has reached its limit in providing additional critical information to further improve treatment strategy, numerous molecular aberrations occurring in lung cancers have been explored as potential new diagnostic markers and markers for molecular sub-staging. Despite extensive studies, most results remain largely controversial. This manuscript will briefly review molecular/genetic changes that have been investigated as candidate diagnostic, prognostic and predictive markers and as biomarkers for early detection in lung cancer. A more concerted and global approach to study the clinical relevance of molecular changes in lung cancers is required in the future.

Abstract
The aim of this study was to determine whether quantitative information obtained from [(18)F]fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) has a prognostic significance for patients with non-small cell lung cancer (NSCLC). We investigated (18)F-FDG PET imaging of 73 patients with NSCLC. The maximum standardized uptake value (SUV(max)) was significantly different between the histopathological types of tumour (squamous cell carcinoma (n=37, 12.4+/-5.1), adenocarcinoma (n=30, 8.2+/-5.8), bronchioloalveolar carcinoma (n=4, 2.6+/-1.7), <0.01). In the univariate analysis of all patients, staging (P=0.0001), tumour cell type (P=0.013), and a SUV(max) greater than 7 (P=0.0011) was correlated with survival. However, a multivariate analysis identified staging and SUV(max) greater than 7 were affected survival adversely. The mortality rate of patients with group I disease (stage I to stage IIIA) was 5.8 times lower than that of patients with group II disease (stage IIIB to stage IV). Patients with a high SUV(max) (> or =7) had a 6.3 times higher mortality than those with a low SUV(max)(<7). By multivariate analysis of patients with squamous cell carcinoma, only grouping affected survival (P=0.008, relative risk=4.3). In the case of adenocarcinoma, the SUV(max) (>10) correlated exclusively with poorer survival (P=0.031, relative risk=11.152). (18)F-FDG uptake correlated with survival in NSCLC. Especially in adenocarcinomas, the SUV(max) was complementary to other known prognostic factors.

Abstract
Non-small cell lung cancer (NSCLC) is a malignant tumor with poor prognosis. Although the prognostic variables determining short-term survival have been well described, relatively little attention has been paid to factors associated with long-term survival. In search of these factors we studied the expression of several molecular markers in NSCLC. Only tumor samples of patients with squamous cell carcinomas and stage III tumors with a postoperative survival of at least 5 years and those of patients who died within 2 years after resection were selected for this study. The expression of several parameters including oncogene and suppressor gene products, proliferative, apoptotic, angiogenic and resistance-related factors were investigated and the differences in these two extreme populations were determined by the Wilcoxon rank sum test. Factors involved in proliferation (ras, fos, erbB-1, jun, cyclin A) were downregulated whereas factors involved in apoptosis (p53, bcl-2, CD95) were upregulated in the long survival group. Direct measurement of parameters of proliferation (cell cycle analysis by flow cytometry, PCNA index) revealed a lower proliferative activity in tumors of the long survivors compared to short survivors. In conclusion, tumors of the long survival group are characterized by a downregulation of factors involved in proliferation and an upregulation of factors involved in apoptosis. These tumors may grow more slowly and this may influence long-term survival of patients with NSCLC.

Abstract
BACKGROUND A minority of patients (30-40%) with advanced non-small cell lung cancer (NSCLC) have objective responses to chemotherapy. Therefore, defining molecular features that determine resistance or response to chemotherapy would have important implications in this disease. Several studies have suggested that patients whose tumors have neuroendocrine features may be more responsive to chemotherapy. In addition, increased expression of p53 may play a role in chemotherapy resistance in patients with NSCLC. METHODS The objective of this study was to analyze retrospectively, the correlation between marker expression and response to chemotherapy and survival using immunohistochemistry for neuroendocrine markers and p53. Ninety patients with unresectable stage III or IV NSCLC, treated with platinum based combination chemotherapy were evaluated. The pathological specimens were obtained prior to chemotherapy. RESULTS There was no statistically significant correlation between any individual marker and response to chemotherapy. However, patients with tumors with increased expression of p53 were more likely to have progressive disease following chemotherapy (P=0.02). Similarly, patients with tumors lacking neuroendocrine expression and with increased expression of p53 were more likely to have progressive disease when compared to patients with tumors with normal p53 expression and neuroendocrine differentiation (P=0.03). Normal expression of p53 along with the presence of neuroendocrine differentiation was a favorable factor for both survival (P=0.05) and time to disease progression (P=0.04) in the multivariate analysis. CONCLUSION The presence of neuroendocrine markers alone was not predictive of response to chemotherapy and did not impact on the survival of this group of patients with advanced stage NSCLC. The normal expression of p53 together with neuroendocrine differentiation seems to impact favorably on overall survival time and time to disease progression without significant improvement in response to chemotherapy.

Abstract
Treatment of early-stage (I, II, and some IIIA) non-small-cell lung cancer (NSCLC) is curative resection. Simultaneous isolated adrenal metastasis represents a dilemma. Although many studies addressing the management of adrenal metastasis diagnosed simultaneously with NSCLC have been published, only very few reports of late adrenal metastasis can be found in the literature. Our purpose is to discuss the management of solitary late (metachronous) adrenal metastasis from operable NSCLC based on published experience. We describe a patient with a solitary metachronous adrenal metastasis diagnosed 3 years after resection of NSCLC. Adrenalectomy was done, followed by combination chemotherapy with paclitaxel and carboplatin. MEDLINE literature on similar cases was reviewed and updated. Only 18 cases have been reported from 1965 to 2000. The median interval between the diagnosis of NSCLC and development of adrenal metastasis was 11.5 months. All patients were male. Unilateral adrenal metastases were reported in 15 patients, whereas 3 had bilateral metastases. Five patients were treated with adrenalectomy, and eight patients were treated with adrenalectomy and postoperative adjunctive chemotherapy. Chemotherapy alone was used in two patients and two patients underwent palliative radiation therapy. One patient was treated with intraarterial chemotherapy followed by radiation therapy. Solitary metachronous adrenal metastases are rare. There are no standard treatment guidelines for this group of patients. Review of the literature showed that median survival after treatment was 19 months for the group treated with adrenalectomy followed by chemotherapy; 15 months for the chemotherapy group; 14 months for the adrenalectomy group; and 8 months for the group treated with palliative radiation.

Abstract
Prognostic value of p53 and PCNA expression in non-small cell lung cancer (NSCLC) remains controversial. In this study we determined the relevance of these abnormalities in terms of overall survival and disease-free survival in 95 NSCLC patients who underwent curative pulmonary resection. Expression of p53 was found in 44 samples (45%), expression of PCNA-in 79 samples (83%), and expression of both markers-in 35 samples (36%). There was no relationship between expression of either protein and major clinicopathological characteristics. Median survival for patients with and without p53 expression was 36 and 33 months, respectively and 5-year survival probability-29 and 37%, respectively (P=0.73). Median survival for patients with and without PCNA expression was 36 and 27 months, respectively and 5-year survival probability-35 and 25%, respectively (P=0.60). There was no significant difference in overall survival between particular groups of patients with tumors carrying four possible p53/PCNA phenotypes. In multivariate analysis including patient age, sex, tumor stage, tumor type and differentiation, p53 and PCNA expression, the only variable important for survival was stage of disease. These results suggest the lack of prognostic relevance of p53 and PCNA expression in surgically treated NSCLC patients.

Abstract
OBJECTIVES We attempted to determine if the degree of angiogenesis can serve as a prognostic factor in the case of completely resected non-small cell lung cancer patients, with special reference to the center and the periphery of the tumor tissue. METHOD For 255 Japanese patients who underwent completely resected non-small cell lung cancer (NSCLC), micro vessel density (MVD) was assessed by visual quantification of microvessels immunostained with anti-CD34 monoclonal antibody in 5 m section. Vascular endothelial growth factor (VEGF) was also immunostained on the same paraffin block specimen. RESULTS MVD at the center (MVD-c) and that at the periphery (MVD-p) were frequently different in each individual although a weak positive correlation was observed (r=0.499, P<0.0001). One hundred and one patients with high MVD-p, but not the 107 patients with high MVD-c, showed a significantly higher proportion of advanced stage, larger tumor size and nodal metastasis as compared with MVD. The 5 year survival rate and median survival time for the high MVD-p group were significantly lower than that of low the MVD-p group (43.0%/31 months vs 48.6%/54 months, P=0.0256). As to the relationship among vascular endothelial growth factor (VEGF) and MVD, expression of VEGF was not associated with the degree of MVD. However, patients with high grade MVD-p showed an unfavorable prognosis in cases of high expression of VEGF. CONCLUSION High MVD-p is associated with advancement of NSCLC, and it was particularly apparent in conjunction with high VEGF expression.

Abstract
Several studies have suggested that non-small cell lung cancer (NSCLC) patients whose tumors have neuroendocrine (NE) features may be more responsive to chemotherapy. In addition, increased expression of p53 and HER2 may confer relative chemotherapy resistance and shortened survival. The Cancer and Leukemia Group B performed a series of studies involving sequential chemotherapy followed by radiation for patients with unresectable stage III NSCLC. The objectives of this study were to analyze pathological specimens using immunohistochemistry for NE markers, p53 and HER2 to determine if there was a correlation between marker expression and response or survival. Of 160 eligible patients, 28 (18%) were not evaluable because of inadequate material. The percentage of specimens positive for markers was as follows: neuron-specific enolase 38%, Leu-7 2%, chromogranin A 0%, synaptophysin 5%, > or =2+NE markers 3%, p53 61%, and HER2 65%. There was no statistically significant correlation between any individual marker and response to induction chemotherapy or response to combined chemotherapy/radiation except for synaptophysin. Six of 6 (100%) synaptophysin positive tumors responded by the completion of all therapy compared with 69/125 (55%) synaptophysin negative tumors (P=0.04). None of the individual markers had a significant effect on survival in univariate analysis. Neuron-specific enolase was marginally significant in multivariate analysis (P=0.08). In conclusion, this study did not demonstrate that expression of NE markers, p53 and HER2 were predictive of response to chemotherapy, combined chemotherapy/radiation or for survival in this group of patients with stage III NSCLC. Future studies must employ either different markers or be performed on more adequate surgical specimens.

Abstract
BACKGROUND RCAS1 is a recently discovered antigen molecule expressed on the membrane of cancer cells, and it acts as a ligand for a putative receptor present on immune cells such as T, B and NK cells. It has been suggested that RCAS1 expression is related to the escape of tumors from immune surveillance. In this study, the relation between RCAS1 expression and various clinicopathologic variables, including patient prognosis, was investigated in lung carcinoma through immunohistochemical analysis. METHODS One hundred two surgically resected nonsmall cell lung carcinoma cases were examined histopathologically by means of the monoclonal antibody 22-1-1, which is specific for RCAS1. The correlation between RCAS1 expression and the clinicopathologic features of patients was evaluated. Moreover, the correlation between RCAS1 expression and the survival of patients was analyzed by the Kaplan-Meier method log-rank test, and multivariate analysis was performed by using the Cox proportional hazard model. RESULTS The samples of 48 of the 102 lung carcinoma patients (47.1%) were positive for RCAS1. There were significant correlations between RCAS1 expression and either pathologic staging (P = 0.0003) or tumor differentiation (P = 0.0308). The survival time for the RCAS1-positive group was significantly shorter than that for RCAS1-negative group (P < 0.0001). Moreover, multivariate analysis for overall survival revealed that RCAS1 expression was a significantly independent prognostic factor in nonsmall cell lung carcinoma patients. CONCLUSION These results suggested that RCAS1 expression may play an important role in the immune escape mechanism and that RCAS1 expression may be a good indicator of poor prognosis in patients with nonsmall cell lung carcinoma.

Abstract
In the past few years our knowledge of the molecular pathogenesis of lung cancer has significantly increased. There are several molecular mechanisms involved in the multistage carcinogenesis through which respiratory epithelial cells become preneoplastic and then invasive cancer. In this review we summarize some of these changes including, genomic alterations such as loss of heterozygosity and microsatellite alterations, autocrine-paracrine loops, alterations in oncogenes and tumor suppressor genes, tumor angiogenesis, aberrant promoter methylation and inherited predisposition to lung cancer. Translation of these findings to the clinic is also discussed.

Abstract
OBJECTIVE To investigate the expression of proliferating cell nuclear antigen (PCNA) in both primary tumor and lymph node metastases of pathologic stage IIIA N2 non-small-cell lung carcinoma (NSCLC) and the relation to prognosis. SUMMARY BACKGROUND DATA Although the prognosis of pN2 NSCLC is poor in general, long-term survivors have been reported among patients with completely resected or clinical N0 disease and those with skip metastasis. However, few reports are available on preoperative prognostic predictors. Expression of PCNA is known to be associated with tumor proliferation and is correlated with the prognosis of several carcinomas. METHODS Clinicopathologic factors were investigated in relation to prognosis in 76 patients with pathologic stage IIIA pN2 NSCLC from whom resected surgical specimens were available from both the primary tumor and lymph node metastases for evaluation of PCNA expression. RESULTS A significant correlation was observed between PCNA labeling index in the primary tumor and that in lymph node metastases. The prognosis in patients with PCNA-negative primary tumor (5-year survival rate, 66.0%) was significantly more favorable than that of patients with PCNA-positive primary tumor (5-year survival rate, 21.5%). The prognosis in patients with PCNA-negative metastases was significantly more favorable than that of patients with PCNA-positive metastases. For clinical N2 disease also, the prognosis of patients with PCNA-negative primary tumor was favorable (5-year survival rate, 66.1%). Multivariate analyses showed that PCNA expression and complete resection were significant prognostic factors. CONCLUSIONS Preoperatively diagnosed N2 NSCLC exhibiting negative PCNA expression in primary tumor or lymph node metastases is expected to result in a favorable postoperative prognosis and may be an indication for primary resection.

Abstract
PURPOSE The purpose of this study was to investigate the relationship between smoking and p53 tumor suppressor gene alterations, and their association with clinicopathologic features and prognosis in non-small cell lung cancer (NSCLC). METHODS For 111 of 119 stage I-III NSCLC patients that had been followed prospectively, tumor p53 protein accumulation was measured immunohistochemically (IHC). Staining was evaluated as a score (p53IHCS) combining intensity and percent distribution. RESULTS Forty-eight of 111 (43%) tumors had p53IHCS > 1. p53 IHC was associated with increasing tumor size (T) (p = 0.035), nodal status (N) (p = 0.091), stage (p = 0.054), and histology: squamous cell carcinoma (70%) and adenocarcinoma (27%) (p = 0.0002). In logistic regression analysis, p53 IHC was associated with squamous cell histology versus other histotypes [adjusted odds ratio (OR)5.90, 95% confidence interval (CI) 2.34-14.90]. p53 IHC was not associated with smoking variables. In multivariate proportional hazards analysis, p53IHCS and pack-years smoked (PY), both as continuous variables, were negative prognostic factors. The adjusted hazard ratios (HR) for the survival outcome recurrence for p53IHCS and PY were 1.20 (95% CI 1.02-1.40) and 1.03 (95% CI 1.01-1.04), and for death due to recurrent disease (DRD) were 1.35 (95% CI 1.11-1.64) and 1.03 (95% CI 1.01-1.04), respectively. Comparing the 75th percentile to the baseline 0, the adjusted HR for p53IHCS (5 vs. 0) was 4.5 and for PY (55 vs. 0) was 5.1 for the outcome DRD. Both variables demonstrated a dose-response relationship with survival. CONCLUSIONS PY and p53IHCS are significant, independent and important predictors of recurrence and DRD in stage I-III NSCLC.

Abstract
OBJECTIVE We determined the prognostic value of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) for patients with treated lung cancer. MATERIALS AND METHODS We examined patients who underwent FDG PET after first-line treatment for non-small cell lung cancer. FDG PET results were correlated with survival rates to determine whether FDG PET findings were predictive of outcomes. RESULTS After initial therapy, 113 patients with non-small cell lung cancer underwent FDG PET. One hundred patients had positive FDG PET results and a median survival of 12 months (95% confidence interval, 9.2-15.4). Thirteen patients had negative FDG PET results, and 11 (85%) of these patients are still living at a median follow-up of 34 months. The difference in survival for patients with positive and negative FDG PET results was statistically significant (p = 0.002). CONCLUSION FDG PET has prognostic value and strongly correlates with survival rates of patients with treated lung cancer. Patients with positive FDG PET results have a significantly worse prognosis than patients with negative results. Additionally, FDG PET may be helpful in guiding therapeutic treatments.

Abstract
Lung cancer is the largest cancer killer of men and women in the united states. In addition to the progress made from antismoking primary prevention measures, new tools to help treat patients with lung cancer are emerging from the rapid advances in knowledge of the molecular pathogenesis of lung cancer. These tools include molecular and cellular biology and are starting to provide an insight into how the tumor cell, by altering oncogenes and tumor suppressor genes, achieves growth advantage, uncontrolled proliferation and metastatic behavior via disruption of key cell-cycle regulators and signal transduction cascades. Moreover, new knowledge is being developed in terms of the molecular definition of individual susceptibility to tobacco smoke carcinogens. These tools are being translated into clinical strategies to complement surgery, radiotherapy, and chemotherapy and also to assist in primary and secondary prevention efforts. This review summarizes current knowledge of the molecular pathogenesis of lung cancer. From this we know that respiratory epithelial cells require many genetic alterations to become invasive and metastatic cancer. We can detect cells with a few such changes in current and former smokers, offering the opportunity to intercede with a biomarker-monitored prevention and early detection effort. This will be coupled with new advances in computed tomography-based screening. Finally, because the molecular alterations are known, new mechanism-based therapies are being developed and brought to the clinic, including new drugs, vaccines, and gene therapy, which also must be integrated with standard therapies.

Abstract
We performed a retrospective analysis of potential prognostic markers in 260 patients with surgically resected stage I and II non small-cell lung cancer (NSCLC) with a minimum 5-year follow-up. Cox proportional hazard models and Wilcoxon tests were employed to analyze the effect of patient characteristics on survival and disease-free survival (DFS). In the univariate analysis, the following were significant predictors of shorter overall survival: N-stage (N1 vs N0) (p<0.001); T-stage (T2 vs T1) (p<0.001); antigen A (loss vs presence) (p<0.01); cough (present vs absent) (p=0.01); bcl-2 expression (positive vs negative) (p=0.03); age (>63.5 vs <63.5) (p=0.03); mucin (positive vs negative) (p<0.03). The following were significant predictors of shorter DFS: N-stage (p<0.001); T-stage (p=0.001); loss of antigen A (p=0.01); mucin expression (p<0.01); cough (p=0.02); Ki-67 expression (p=0.02) and negative bcl-2 expression (p=0.03). Analysis of survival difference for histologic subtype, degree of differentiation, aneuploidy, %S-phase, codon 12 K-ras mutation, and immunohistochemistry staining for Lewisy, p53, Rb, microvessel count, HER2, E-cadherin and neuroendocrine markers did not reach statistical significance. In multivariate analysis, the following predicted for shorter overall survival: N-stage (p<0.01), antigen A (p=0.01), age (p<0.01), and bcl-2 (p=0.05); and for DFS, N-stage (p<0.01), antigen A (p<0.01), Ki-67 (p=0.03), mucin (p=0.04) and T-stage (p=0.05). Of all the clinical-pathological, proliferative, and biological markers studied, only a few carried independent prognostic significance.

Abstract
BACKGROUND The outcome of treatment in non-small cell lung cancer (NSCLC) remains poor. One of the reasons is that in many patients its biological behavior does not follow a definite pattern, and can not be accurately predicted prior to treatment. In the present study we have examined the significant prognostic predictors. METHODS One hundred and fifty-eight patients with NSCLC entered this study. They received surgery alone (95 cases) or combined therapy with postoperative irradiation (63 cases). Three types of data have been collected: (1) clinical characteristics: age, sex, Karnofsky performance status, weight loss, T stage, and N stage; (2) histopathology studies: histological types, tumor differentiation, status of vascular and lymphatic vessel invasions; (3) laboratory measurements by immunohistochemistry assay: oncoprotein overexpression, including pan-ras, c-myc, neu, epidermal growth factor receptor (EGFR) and p53, and tumor cell proliferation by proliferating cell nuclear antigen (PCNA). RESULTS For the entire group, 5-year actuarial survival, local control and distant metastasis rates were 44, 63 and 40%, respectively. In the univariate analyses, T stage, N stage and lymphatic vessel invasion correlated to survival; T stage and N stage to local control; N stage, lymphatic vessel invasion and pan-ras protein positive stain to distant metastasis. When the index of oncoprotein positive stains was used, the higher index was associated with a higher distant metastasis rate. In the multivariate analyses, T stage, N stage and lymphatic vessel invasion could be independent predictors for survival; T stage for local control; N stage, lymphatic vessel invasion and index of positive oncoprotein stains for distant metastasis. CONCLUSIONS Late T and N stages, lymphatic vessel invasion and multi-oncoprotein positive stains would predict poor prognoses for NSCLC.

Abstract
BACKGROUND Tumor cell motility is an important characteristic that facilitates the multistep process of tumor metastasis. Rac, ABP-280, and gelsolin are proteins that interact with actin and are important in cell motility. METHODS The authors studied a cohort of 229 Stage I nonsmall cell lung carcinoma (NSCLC) patients who had a minimum of 3 years follow-up and had been previously analyzed for 22 clinical, pathologic, and molecular features, of which 9 had been found to provide significant prognostic information in a Cox proportional hazards model. Tumor sections were stained by the avidin-biotin complex method using monoclonal antibodies against rac, ABP-280, and gelsolin. RESULTS In a pilot analysis of over 50 patients each, rac and ABP-280 were found to be moderately-to-highly expressed in the majority of tumors and to provide no prognostic information. Gelsolin expression was more variable and appeared to be negatively correlated with survival in the pilot population. In the larger 229-patient population, high focal gelsolin expression was seen in 32 tumors (14%) and conferred the highest relative risk (4.04) of cancer recurrence among all factors tested, compared with tumors that had no or low gelsolin expression. Moderate focal gelsolin expression, seen in 46 patients (20%), also conferred a significant risk of cancer recurrence, with a relative risk of 2.26 compared with tumors that had no or low gelsolin expression. Consideration of average gelsolin expression and of overall survival yielded similar results. CONCLUSIONS Gelsolin expression appears to be a significant prognostic factor for cancer recurrence in cases of Stage I NSCLC.

Abstract
BACKGROUND The role of Lewis y (Le(y)) antigen expression has been studied extensively in predicting the outcome of various malignancies. We evaluated the expression of Le(y) and its relationship to survival, disease-free survival and other clinicopathologic variables in patients with stage I and II non-small cell lung cancer (NSCLC). OBJECTIVE To investigate the prognostic significance of Le(y) antigen expression in a large group of well characterized patients with resected stage I and II NSCLC. PATIENTS Two hundred and sixty patients with surgically resected stage I (n = 193) and II (n = 67) NSCLC with at least 5-year follow-up were identified. RESULTS The median survival for patients with negative expression of Le(y) (< 50% of cells that were positive) was 46 months, whereas for those with positive expression of Le(y) (> or = 50%), the median survival was 54 months (p = 0.99). The disease-free survival for patients with Le(y)(-) expression was 39 months and 34 months for patients with Le(y)(+) expression (p = 0.3). CONCLUSIONS We found no relationship between loss of blood group antigen A and expression of Le(y). No statistically significant difference was found in survival between positive and negative expression of Le(y) antigen in patients with resected stage I and II NSCLC.

Abstract
We review the molecular pathogenesis of lung cancer including alterations in dominant oncogenes, recessive oncogenes/tumor suppressor genes, alterations in growth regulatory signaling pathways, abnormalities in other pathways, such as apoptosis, autocrine and paracrine growth stimulatory loops, angiogenesis, and host immune responses, other mechanisms of genetic changes, such as microsatellite and methylation alterations, and the potential for inherited predisposition to lung cancer. These changes are related to multistage carcinogenesis involving preneoplastic lesions, and lung development and differentiation. The translational applications of these findings for developing new ways of early detection, prevention, treatment, and prognosis of lung cancer are discussed.

Abstract
A series of 85 lung/bronchial tissue samples from 76 patients consisting of normal, metaplastic and dysplastic epithelium and different types of lung carcinomas were analyzed for the distribution of hyaluronan (HA), using a biotinylated hyaluronan binding complex as an HA-specific probe. The normal pseudo-stratified columnar bronchial epithelium was either negative for HA or displayed a weak staining around the basal cells. The epithelia of serous and mucous bronchial glands were HA negative whereas the submucosal connective tissue was strongly positive. In metaplastic, dysplastic and carcinoma in situ lesions the whole epithelium from basal to uppermost cells expressed HA on plasma membranes. Epithelial HA was also found in squamous cell carcinomas, but not in adenocarcinomas, carcinoid tumors or small cell carcinomas of the lung. Whereas epithelial HA was present in all lesions of the squamous cell type, the staining intensity displayed great local variability in 50% of the cases with severe dysplasia, carcinoma in situ and squamous cell carcinomas. In squamous cell carcinomas, such an irregular staining pattern was significantly associated with poor differentiation. Our results indicate that the expression of HA in different bronchial lesions and lung tumors is restricted to those showing squamous cell differentiation, being absent from other types of lung carcinomas. The increase of HA depleted areas in poorly differentiated squamous cell carcinomas emphasizes the important role of HA in tumor differentiation. HA on carcinoma cell surface may influence tumor growth and metastatic behavior.

Abstract
The proliferative rate of a tumor has been considered predictive of its clinical course. We evaluated the expression of the proliferative marker Ki-67 and its relationship to survival, disease-free survival and other clinicopathologic variables in both stage I and stage II non-small cell lung cancer (NSCLC). A total of 260 patients with surgically resected stage I (n = 193), and II (n = 67) NSCLC with at least 5 years follow-up were identified. The median survival for patients with low expression of Ki-67 (< or = 25%) was 54 months, while for those with high expression (> 25%), it was 45 months (P = 0.1). The disease-free survival in patients with low expression of Ki-67 was 59 months while it was only 32 months for patients with high Ki-67 (P = 0.1). Out of 136 patients, 84 (62%) had both increased S-phase (> 8%) and high Ki-67 (P = 0.001). A total of 28 of 30 patients who had loss of antigen A had high expression of Ki-67 (93.3%) (P = 0.03). Ki-67 expression was also higher in squamous cell (54/63, 85.7%) compared to nonsquamous cell cancer (70/108, 64%) (P = 0.03). We also analyzed for the presence of symptoms with survival. The presence of symptoms was not found to be statistically significant, for overall survival (P = 0.33) or disease-free survival (P = 0.72). When individual symptoms were analyzed, the presence of cough was statistically significant for both overall and disease-free survival. The median survival was 39 months for patients with cough, and 57 months for patients without cough (P = 0.04). Multivariate analysis showed higher N and T stages, presence of cough and loss of antigen A, predicted for poorer overall survival. Higher N and T stages, loss of antigen A, presence of mucin and cough and increased expression of Ki-67 predicted decreased disease-free survival. Although we did not find a statistically significant difference between low and high Ki-67, there was a trend for a poorer overall and disease-free survival in patients with high Ki-67 expression. Larger studies may be needed to prove a statistically significant effect of Ki-67 on survival. Future studies should assess the potential prognostic significance of the presence of symptoms (particularly cough) in addition to clinical-pathologic variables (such as T and N stage) and biological markers in patients with early stage NSCLC.
