Objective: To evaluate the influence of lung adenocarcinoma second predominant pattern on the maximal standard uptake value (SUVmax) and its prognostic effect in different histologic groups. Methods: We retrospectively collected surgically resected pathologic stage I and II lung adenocarcinoma from nine European institutions. Only patients who underwent preoperative PET-CT and with available information regarding SUVmax of T (SUVmaxT) and N1 (SUVmaxN1) component were included. Results: We enrolled 344 patients with lung adenocarcinoma. SUVmaxT did not show any significant relation according to the second predominant pattern ( p = 0.139); this relationship remained nonsignificant in patients with similar predominant pattern. SUVmaxT influenced the disease-free survival in the whole cohort ( p = 0.002) and in low- and intermediate-grade predominant pattern groups ( p = 0.040 and p = 0.008, respectively). In the high-grade predominant pattern cohort and in the pathologic N1 cases, SUVmaxT lost its prognostic power. SUVmaxN1 did not show any significant correlation with predominant and second predominant patterns and did not have any prognostic impact on DFS. Conclusions: SUVmaxT is influenced only by the adenocarcinoma predominant pattern, but not by second predominant pattern. Concurrently, in high-grade predominant pattern and pN1 group the prognostic power of SUVmaxT becomes nonsignificant.

Objective. The aim of this study was to investigate the prognostic value ofMicroRNA-210(miR-210) expression in patients with non-small-cell lung cancer (NSCLC).Methods. We examined themiR-210expression of samples of 80 patients, who underwent surgical resection at Fukushima Medical University from 2004 to 2007, by using quantitative RT-PCR. The relationship betweenmiR-210expression and clinicopathological factors as well as histological subtype was statistically analyzed.Results.miR-210expression showed an inverse correlation with disease-free and overall survival in patients with NSCLC. Significant correlations were found betweenmiR-210expression and lymph node metastasis, late disease stages, and poor prognosis in patients with adenocarcinoma. Multivariate Cox analysis indicated thatmiR-210expression was an independent prognostic factor for disease-free survival in patients with adenocarcinoma.Conclusions. We showed thatmiR-210may be a prognostic biomarker for patients with NSCLC, especially for those with lung adenocarcinoma.

Malignant Behavior

7573 Background: The malignant behavior of small lung adenocarinomas (AD), which have been detected with increasing frequency recently, has not yet been clearly evaluated, and an understanding of this biological characteristic is vital for selecting the appropriate therapeutic strategy. We examined the malignancy grade of small lung ADs using FDG-PET/CT (PET), in addition to high-resolution CT (HRCT) and pathologic evaluation in a multicenter setting. Methods: A total of 204 patients with cT1N0M0 AD underwent PET and HRCT, followed by complete resection with lymph node dissection. The associations between components of bronchioloalveolar carcinoma (BAC) on pathologic examination and maximum standardized uptake value (maxSUV) on PET, ground-glass opacity (GGO) ratio and tumor disappearance rate (TDR) on HRCT were examined, and these findings were analyzed in relation to pathologic features and surgical outcomes. To reduce the errors in PET machines used for this analysis, maxSUV data were adjusted using an anthropomorphic body phantom of the NEMA standards (corrected maxSUV). Results: Examination of tumor aggressiveness based on the presence of lymphatic, vascular and pleural invasion, and of nodal metastasis, showed that maxSUV, BAC ratio, TDR, and GGO ratio, in the order, can reflect the malignancy grade. MaxSUV and BAC ratio were also valuable prognostic predictors of the disease-free survival. There were no significant differences in the values between maxSUV and corrected maxSUV. Although BAC ratio was significantly associated with maxSUV, GGO ratio and TDR (all p<0.0001), the degree of association with maxSUV (R2=0.2533) was weaker than that with GGO (R2=0.5843) ratio or TDR (R2=0.5123). Conclusions: A higher maxSUV reflects an aggressive malignant behavior of cT1N0M0 ADs, independently of BAC component. Assessment by PET in addition to HRCT is useful for selection of the appropriate treatment strategy for small lung AD. [Table: see text] No significant financial relationships to disclose.

Recent studies have reported that SERPINE2 contributes to the development of various cancers. However, its association with urothelial carcinoma (UC) remains unclear. In this study, data on urinary bladder UC (UBUC) cases from The Cancer Genome Atlas (TCGA) database were used to investigate the prognostic value of SERPINE2 mRNA expression. Then, SERPINE2 expression was analyzed with tissue microarrays constructed from 117 upper tract UC (UTUC) and 84 UBUC tissue specimens using immunohistochemical staining. Results were compared to clinicopathologic data by multivariate analysis. In the TCGA database, high SERPINE2 mRNA expression indicated a poor prognosis in patients with UBUC. Furthermore, Mann–Whitney U test showed that high SERPINE2 immunoexpression was significantly associated with adverse pathologic parameters including invasion, high grade, coexistence of UC in situ, and advanced pT stage (all p < 0.05, except for a marginal association with high-grade UBUC, p = 0.066). Kaplan–Meier analysis revealed that high SERPINE2 expression was associated with worse overall survival (OS; UTUC, p = 0.003; UBUC, p = 0.014) and disease-free survival (UTUC, p = 0.031; UBUC, p = 0.033). Moreover, multivariate analysis identified high SERPINE2 expression as an independent prognostic factor for OS (UTUC, p = 0.002; UBUC, p = 0.024). Taken together, our findings demonstrated that increased SERPINE2 expression is associated with adverse pathologic features and may serve as a prognostic biomarker for UC.

Abstract Purpose:Intratumoral macrophages are reportedly involved in tumor progression in non-small cell lung cancer; however, little is known about the prognostic impact and function of alveolar macrophages (AMs). This study aims to investigate the prognostic impact of the number of peritumoral AMs in patients with stage I lung adenocarcinoma.Methods:We investigated 514 patients with pathological stage I lung adenocarcinoma who underwent complete resection with lobectomy or pneumonectomy. The number of peritumoral AMs were counted, and patients were classified into two groups based on the number of peritumoral AMs. Using the Cancer Genome Atlas (TCGA) database of stage I lung adenocarcinoma, we compared gene expression profiles of high and low peritumoral AM contents.Results:The median number of peritumoral AMs per alveolar space was 15.5. Patients with a high peritumoral AM content had significantly shorter disease-free survival and overall survival than patients with a low peritumoral AM content (both p < 0.01). In the multivariate analyses, a higher number of peritumoral AMs was an independent prognostic factor (p = 0.02). The analysis of TCGA database revealed that patients with a high peritumoral AM content had shorter disease-free survival than those with a low peritumoral AM content (p = 0.04). Gene expression analysis of TCGA stage I lung adenocarcinoma revealed enrichment of biological processes, such as chemotaxis and epithelial proliferation, in patients with a high peritumoral AM content.Conclusion:The number of peritumoral AMs had a strong impact on disease-free survival in patients with stage I lung adenocarcinoma.

Abstract Objectives This study aimed to describe the impact of adverse clinical and pathologic features in sinonasal squamous cell carcinoma (SCC). Design This study is designed with retrospective chart review. Setting present study conducted at a tertiary care institution. Participants All patients treated surgically for sinonasal SCC at our tertiary care institution between January 2006 and December 2013. Main Outcome Measures Overall survival (OS) and disease free survival (DFS) are the final measurement of this study. Results Forty-eight patients were identified. Mean age at surgery was 65.8 years, and mean follow-up time was 40.7 months. Eighteen patients (38%) had T1–T3 disease, while 30 patients (63%) had T4 disease. Seven patients (8.3%) had nodal disease at presentation. At 2, 5, and 10 years, OS was 71, 54, and 48%, respectively, while DFS was 64, 51, and 45%, respectively. Twelve patients (25%) experienced local recurrences with mean time to recurrence of 15.3 months. Twenty-five patients (52%) had positive margins, 24 (50%) had high-grade tumors, 18 (38%) had perineural invasion (PNI), and 15 (31%) had lymphovascular invasion (LVI). In the univariate analysis, T4 disease (risk ratio [RR] = 2.7) and high grade (RR = 2.4) had a significant association with DFS. In the multivariate analysis, high grade (RR = 4.0 and 4.5) and LVI (RR = 4.1 and 4.7) had a significant association with OS and DFS. Conclusion Our single-institution experience of 48 patients suggests that high grade and LVI are independently associated with survival outcomes in sinonasal SCC, while PNI and microscopically positive margins do not have a significant impact.

Purpose: The aims of the present study were to: 1- critically assess the utility of L-3,4- dihydroxy-6-18Ffluoro-phenyl-alanine (18F-DOPA) and O-(2-18F-fluoroethyl)-L-tyrosine (18F-FET) Positron Emission Tomography (PET)/Computed Tomography (CT) in patients with high grade glioma (HGG) and 2- describe the results of 18F-DOPA and 18F-FET PET/CT in a case series of patients with recurrent HGG. Methods: We searched for studies using the following databases: PubMed, Web of Science and Scopus. The search terms were: glioma OR brain neoplasm and DOPA OR DOPA PET OR DOPA PET/CT and FET OR FET PET OR FET PET/CT. From a mono-institutional database, we retrospectively analyzed the 18F-DOPA and 18F-FET PET/CT of 29 patients (age: 56 ± 12 years) with suspicious for recurrent HGG. All patients underwent 18F-DOPA or 18F-FET PET/CT for a multidisciplinary decision. The final definition of recurrence was made by magnetic resonance imaging (MRI) and/or multidisciplinary decision, mainly based on the clinical data. Results: Fifty-one articles were found, of which 49 were discarded, therefore 2 studies were finally selected. In both the studies, 18F-DOPA and 18F-FET as exchangeable in clinical practice particularly for HGG patients. From our institutional experience, in 29 patients, we found that sensitivity, specificity and accuracy of 18F-DOPA PET/CT in HGG were 100% (95% confidence interval- 95%CI - 81-100%), 63% (95%CI: 39-82%) and 62% (95%CI: 39-81%), respectively. 18F-FET PET/CT was true positive in 4 and true negative in 4 patients. Sensitivity, specificity and accuracy for 18F-FET PET/CT in HGG were 100%. Conclusion: 18F-DOPA and 18F-FET PET/CT have a similar diagnostic accuracy in patients with recurrent HGG. However, 18F-DOPA PET/CT could be affected by inflammation conditions (false positive) that can alter the final results. Large comparative trials are warranted in order to better understand the utility of 18F-DOPA or 18F-FET PET/CT in patients with HGG.

Background: The ratio of hemoglobin to red cell distribution width (HRR) has been described as an effective prognostic factor in several types of cancer. The aim of this study was to investigate the prognostic role of preoperative HRR in resected-lung-adenocarcinoma patients. Methods: We enrolled 342 consecutive patients. Age, sex, surgical resection, adjuvant treatments, pathological stage, preoperative hemoglobin, red cell distribution width, and their ratio were recorded for each patient. Results: Mean age was 66 years (SD: 9.0). There were 163 females (47.1%); 169 patients (49.4%) had tumors at stage I, 71 (20.8%) at stage II, and 102 (29.8%) at stage III. In total, 318 patients (93.0%) underwent lobectomy, and 24 (7.0%) pneumonectomy. Disease-free survival multivariable analysis disclosed an increased hazard ratio (HR) of relapse for preoperative HRR lower than 1.01 (HR = 2.20, 95%CI: (1.30–3.72), p = 0.004), as well as for N1 single-node (HR = 2.55, 95%CI: (1.33–4.90), p = 0.005) and multiple-level lymph node involvement compared to N0 for both N1 (HR = 9.16, 95%CI:(3.65–23.0), p < 0.001) and N2 (HR = 10.5, 95%CI:(3.44–32.2, p < 0.001). Conclusion: Pre-operative HRR is an effective prognostic factor of disease-free survival in resected-lung-adenocarcinoma patients, together with the level of pathologic node involvement.
