PurposeHepatoma-derived growth factor (HDGF), which is unrelated to hepatocyte growth factor, can stimulate DNA synthesis and cell proliferation on entering the nucleus. We hypothesize that HDGF plays an important role in biologic behavior of early-stage non–small-cell lung cancer (NSCLC).Patients and MethodsNinety-eight patients with pathologic stage I NSCLC who underwent curative surgery were studied. Immunohistochemistry was used to determine the expression level of HDGF in the tumor specimens. The intensity of the protein staining and percentage of stained tumor cells were used to determine a labeling index. Statistical analyses, all two-sided, were performed to determine the prognostic effect of HDGF expression levels on clinical parameters and outcomes.ResultsThe mean ± standard deviation HDGF labeling index in the 98 tumors was 185 ± 41. Patients whose tumors had higher HDGF indexes (≥ 185) had a significantly poorer probability of overall survival at 5 years after surgery than did those with lower HDGF indexes (0.26 v 0.82; P < .0001). Similarly, the 5-year disease-specific and disease-free survival probabilities were lower in those with higher HDGF indexes (0.42 v 0.92, and 0.34 v 0.71; P < .0001 and P = .0008; respectively). Multivariate analysis indicated that HDGF level was an independent predictor of overall, disease-specific, and disease-free survivals.ConclusionOverexpression of HDGF is common in early-stage NSCLC. The expression level in tumor cells is strongly correlated with poor overall, disease-specific, and disease-free survivals, suggesting HDGF may be a powerful prognostic marker for patients with early-stage NSCLC.

7662 Background: Epigenetic modifications, such as methylation and/or acetylation of histones, may contribute to the development and progression of cancer. We investigated whether histone modifications influence prognosis of non-small cell lung cancer (NSCLC). Methods: We used immunohistochemistry to assess histone 3 lysine 4 dimethylation (H3K4diMe), and acetylation of histone 2A lysine 5 (H2AK5Ac), histone 2B lysine 12 (H2BK12Ac), histone 3 lysine 9 (H3K9Ac), and histone 4 lysine 8 (H4K8Ac), in resected tumor samples of 138 NSCLC patients. In addition, the genotype of a tandem repeat polymorphism in the histone 3 methyltransferase SMYD3 gene was determined using PCR and capillary electrophoresis. Data were analyzed using a recursive partitioning analysis (RPA). Results: The overall median expression of H3K4diMe, H2AK5Ac, H2BK12Ac, H3K9Ac, and H4K8Ac were 75, 10, 0, 25, and 80%, respectively. The RPA classified the patients into seven distinct prognostic groups based on TNM stage (first node), histology (second node) and histone modifications (third node). H3K4diMe (< or =85% tumor cells), H3K9Ac (< or =68% tumor cells) and H2AKAc (< or =5% tumor cells) were retained by RPA. The SMYD3 genotype was not retained by RPA. The seven groups were associated with significantly different disease- free (p<0.0001) and overall survival (p<0.0001). Interestingly, the four groups determined by stage I patients (below the first node) displayed dramatic differences in survival (median from 10 months in adenocarcinoma, H3K9Ac=68%, to 147 months in non-adenocarcinoma, H3K4diMe=85%). Conclusions: The prognostic influence of global histone modifications is greater in early stage NSCLC and it may help in the selection of early stage NSCLC patients for adjuvant treatment and provides a rationale for the use of combination of standard chemotherapy with drugs interacting with histone modifications such as histone deacetylases (HDAC) inhibitors.

Lung cancer is a leading cause of cancer-related deaths worldwide. Radiotherapy is an essential treatment modality for inoperable non-small cell lung cancer (NSCLC). Stereotactic body radiotherapy (SBRT) is the standard treatment for early-stage NSCLC because of its favorable local control (LC) compared to conventional radiotherapy. Carbon ion radiotherapy (CIRT) is a kind of external beam radiotherapy characterized by a steeper dose distribution and higher biological effectiveness. Several prospective studies have shown favorable outcomes. However, there is no direct comparison study between CIRT and SBRT to determine their benefits in the management of early-stage NSCLC. Thus, we conducted a retrospective, single-institutional, and contemporaneous comparison study, including propensity score-adjusted analyses, to clarify the differences in oncologic outcomes. The 3-year overall survival (OS) was 80.1% in CIRT and 71.6% in SBRT (p = 0.0077). The 3-year LC was 87.7% in the CIRT group and 79.1% in the SBRT group (p = 0.037). Multivariable analyses showed favorable OS and LC in the CIRT group (hazard risk [HR] = 0.41, p = 0.047; HR = 0.30, p = 0.040, respectively). Log-rank tests after propensity score matching and Cox regression analyses using propensity score confirmed these results. These data provided a positive efficacy profile of CIRT for early-stage NSCLC.

Circulating exosomal microRNAs (ExmiRNAs) provide an ideal non-invasive method for cancer diagnosis. In this study, we evaluated two circulating ExmiRNAs in NSCLC patients as a diagnostic tool for early-stage non-small lung cancer (NSCLC). The exosomes were characterized by qNano, transmission electron microscopy, and Western blot, and the ExmiRNA expression was measured by microarrays. The differentially expressed miRNAs were verified by RT-qPCR using peripheral blood specimens from NSCLC patients ( n = 276, 0 and I stage: n = 104) and healthy donors ( n = 282). The diagnostic values were measured by receiver operating characteristic (ROC) analysis. The results show that the expression of both ExmiR-20b-5p and ExmiR-3187-5p was drastically reduced in NSCLC patients. The area under the ROC curve (AUC) was determined to be 0.818 and 0.690 for ExmiR-20b-5p and ExmiR-3187-5p, respectively. When these two ExmiRNAs were combined, the AUC increased to 0.848. When the ExmiRNAs were administered with either carcinoembryonic antigen (CEA) or cytokeratin-19-fragment (CYFRA21-1), the AUC was further improved to 0.905 and 0.894, respectively. Additionally, both ExmiR-20b-5p and ExmiR-3187-5p could be used to distinguish early stages NSCLC (0 and I stage) from the healthy controls. The ROC curves showed that the AUCs were 0.810 and 0.673, respectively. Combination of ExmiR-20b-5p and ExmiR-3187-5p enhanced the AUC to 0.838. When CEA and CYFRA21-1 were administered with the ExmiRNAs, the AUCs were improved to 0.930 and 0.928, respectively. In summary, circulating serum exosomal miR-20b-5p and miR-3187-5p could be used as effective, non-invasive biomarkers for the diagnosis of early-stage NSCLC, and the effects were further improved when the ExmiRNAs were combined. Impact statement The high mortality of non-small cell lung cancer (NSCLC) is mainly because the cancer has progressed to a more advanced stage before diagnosis. If NSCLC can be diagnosed at early stages, especially stage 0 or I, the overall survival rate will be largely improved by definitive treatment such as lobectomy. We herein validated two novel circulating serum ExmiRs as diagnostic biomarkers for early-stage NSCLC to fulfill the unmet medical need. Considering the number of specimens in this study, circulating serum exosomal miR-20b-5p and miR-3187-5p are putative NSCLC biomarkers, which need to be further investigated in a larger randomized controlled clinical trial.

Purpose Plasma osteopontin (OPN) levels in advanced non–small-cell lung cancer (NSCLC) correlate with therapeutic response and survival, but the utility of plasma OPN for diagnosis and monitoring of early-stage NSCLC has not been investigated. We hypothesize that plasma OPN levels are elevated in early-stage NSCLC and decrease with resection. Patients and Methods Presurgery plasma OPN levels (in ng/mL) were measured by enzyme-linked immunosorbent assay (ELISA) in a discovery set of 60 patients with early-stage NSCLC and were compared with data from 56 cancer-free smokers. Presurgery OPN was validated in an independent cohort of 96 patients with resectable NSCLC. The presurgery levels in the latter cohort were compared with matched postsurgery levels. Perioperative OPN levels were correlated with demographics, tumor characteristics, and perioperative events. OPN was monitored during follow-up. Results Discovery set presurgery NSCLC OPN (271 ± 31 ng/mL) was higher than smokers (40 ± 2 ng/mL; P = .001). Presurgery OPN was similar in the NSCLC validation cohort (324 ng/mL ± 20 ng/mL; P = .134). Postsurgery OPN (256 ng/mL ± 21 ng/mL) measured at mean of 9.8 weeks (range, 2 to 46 weeks) was lower than presurgery OPN (P = .005). Time from surgery significantly impacted postsurgery OPN: OPN ≤ 6 weeks postsurgery (303 n/mL ± 26 ng/mL) was higher than OPN greater than 6 weeks postsurgery (177 ng/mL ± 29 ng/mL; P = .003). Multivariate analysis noted correlations between albumin and creatinine to presurgery OPN and use of thoracotomy to postsurgery OPN. Recurrence rate was 5% at 29 weeks mean follow-up. OPN at recurrence was elevated from postsurgery nadir. Conclusion Plasma OPN levels are elevated in early-stage NSCLC. They are reduced after resection and appear to increase with recurrence. Plasma OPN may have utility as a biomarker in early-stage NSCLC.

Abstract Background Radiation-induced lymphopenia (RIL) occurs during treatment with conventional radiation in multiple organ sites. Development of RIL portends poor prognosis. Stereotactic body radiation therapy (SBRT) spares RIL in pancreatic cancer, but has not been examined in other sites commonly treated with SBRT. This work examines if SBRT similarly spares RIL in patients with non-small cell lung cancer (NSCLC). Methods Retrospective analysis was done at a single institution on 40 distinct cases of SBRT for early stage NSCLC from 2006-2017. Incidentally collected lymphocyte counts collected within 6 months of SBRT treatment were analyzed to determine if RIL occurred. The presence of RIL was correlated with location of initial failure and survival endpoints. Kaplan-Meier curves were constructed with significance defined at the level p = 0.05. Results RIL was observed in 35% of the analyzed patients. Patterns of failure and survival data were comparable to prior SBRT literature. There was no observed association in two year local, nodal, or distant failure, progression free survival, or overall survival based on the presence of RIL. Conclusions SBRT spares RIL in NSCLC compared to historical rates observed with conventionally fractionated radiation. As understanding of the role of the immune system in cancer control continues to evolve, the importance of RIL sparing techniques take on increasing importance. This study represents the first analysis of RIL sparing in SBRT in an early stage NSCLC cohort without the confounding influence of chemotherapy.
