Abstract
Recent advances in machine learning research, combined with the reduced sequencing costs enabled by modern next-generation sequencing, paved the way to the implementation of precision medicine through routine multi-omics molecular profiling of tumours. Thus, there is an emerging need of reliable models exploiting such data to retrieve clinically useful information. Here, we introduce an original consensus clustering approach, overcoming the intrinsic instability of common clustering methods based on molecular data. This approach is applied to the case of non-small cell lung cancer (NSCLC), integrating data of an ongoing clinical study (PROMOLE) with those made available by The Cancer Genome Atlas, to define a molecular-based stratification of the patients beyond, but still preserving, histological subtyping. The resulting subgroups are biologically characterized by well-defined mutational and gene-expression profiles and are significantly related to disease-free survival (DFS). Interestingly, it was observed that (1) cluster B, characterized by a short DFS, is enriched in KEAP1 and SKP2 mutations, that makes it an ideal candidate for further studies with inhibitors, and (2) over- and under-representation of inflammation and immune systems pathways in squamous-cell carcinomas subgroups could be potentially exploited to stratify patients treated with immunotherapy.

Abstract
Podocyte injury leading to albuminuria is a characteristic feature of diabetic nephropathy (DN). Hyperglycemia and advanced glycation end products (AGEs) are major determinants of DN. However, the underlying mechanisms of podocyte injury remain poorly understood. The cytosolic protein TNFAIP2/M-Sec is required for tunneling nanotubes (TNTs) formation, which are membrane channels that transiently connect cells, allowing organelle transfer. Podocytes express TNFAIP2 and form TNTs, but the potential relevance of the TNFAIP2-TNT system in DN is unknown. We studied TNFAIP2 expression in both human and experimental DN and the renal effect of tnfaip2 deletion in streptozotocin-induced DN. Moreover, we explored the role of the TNFAIP2-TNT system in podocytes exposed to diabetes-related insults. TNFAIP2 was overexpressed by podocytes in both human and experimental DN and exposre of podocytes to high glucose and AGEs induced the TNFAIP2-TNT system. In diabetic mice, tnfaip2 deletion exacerbated albuminuria, renal function loss, podocyte injury, and mesangial expansion. Moreover, blockade of the autophagic flux due to lysosomal dysfunction was observed in diabetes-injured podocytes both in vitro and in vivo and exacerbated by tnfaip2 deletion. TNTs allowed autophagosome and lysosome exchange between podocytes, thereby ameliorating AGE-induced lysosomal dysfunction and apoptosis. This protective effect was abolished by tnfaip2 deletion, TNT inhibition, and donor cell lysosome damage. By contrast, Tnfaip2 overexpression enhanced TNT-mediated transfer and prevented AGE-induced autophagy and lysosome dysfunction and apoptosis. In conclusion, TNFAIP2 plays an important protective role in podocytes in the context of DN by allowing TNT-mediated autophagosome and lysosome exchange and may represent a novel druggable target.Abbreviations: AGEs: advanced glycation end products; AKT1: AKT serine/threonine kinase 1; AO: acridine orange; ALs: autolysosomes; APs: autophagosomes; BM: bone marrow; BSA: bovine serum albumin; CTSD: cathepsin D; DIC: differential interference contrast; DN: diabetic nephropathy; FSGS: focal segmental glomerulosclerosis; HG: high glucose; KO: knockout; LAMP1: lysosomal-associated membrane protein 1; LMP: lysosomal membrane permeabilization; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; PI3K: phosphoinositide 3-kinase; STZ: streptozotocin; TNF: tumor necrosis factor; TNFAIP2: tumor necrosis factor, alpha-induced protein 2; TNTs: tunneling nanotubes; WT: wild type.

Abstract
PURPOSE The clinical impact of the SIAPEC/SIE 2014 classification for thyroid cytology has been addressed in few studies that evaluated the malignancy rate and the relative prevalence of each category. No study analyzed its intra-observer and inter-observer reproducibility, so far. METHODS We retrospectively collected all "indeterminate" lesions diagnosed before (2011-2014) and after (2015-2018) the application of the SIAPEC/SIE 2014 classification at our Institution. Their relative malignancy risks were calculated based on available histological diagnoses. Cytological and clinical features of TIR3A were compared with the surgical outcome. Finally, a large set of samples was re-evaluated in blind of the original cytological and histological diagnoses by two pathologists, independently. RESULTS The prevalence of "indeterminate" diagnoses increased in years 2015-2018 (302/1482, 21% with 14% of TIR3A and 7% TIR3B categories) compared to years 2011-2014 (261/1680, 16%). Surgery was performed in 27% TIR3A and in 97% TIR3B cases. Malignancy rates were 40% for TIR3B and 17% for TIR3A, but were greatly influenced by the adoption of the WHO 2017 re-classification of encapsulated follicular-patterned lesions (decreasing to 28% and 6%, respectively). No criteria except for tumor size were associated to malignancy in TIR3A category. Intra-observer agreement of the experienced pathologist was 122/141 (86%), whereas inter-observer agreement between the expert and in-training pathologist was 95/141 (67%). CONCLUSIONS In this real-life experience, the sub-classification of TIR3A and TIR3B slightly increased the overall prevalence of "indeterminate" diagnoses. Malignancy rates were higher than estimated for both TIR3A and TIR3B categories. Agreement among observers highly depended on pathologist's training.

Abstract
Background This study evaluated the consequences in Europe of the COVID-19 outbreak on pathology laboratories orientated toward the diagnosis of thoracic diseases. Materials and methods A survey was sent to 71 pathology laboratories from 21 European countries. The questionnaire requested information concerning the organization of biosafety, the clinical and molecular pathology, the biobanking, the workload, the associated research into COVID-19, and the organization of education and training during the COVID-19 crisis, from 15 March to 31 May 2020, compared with the same period in 2019. Results Questionnaires were returned from 53/71 (75%) laboratories from 18 European countries. The biosafety procedures were heterogeneous. The workload in clinical and molecular pathology decreased dramatically by 31% (range, 3%-55%) and 26% (range, 7%-62%), respectively. According to the professional category, between 28% and 41% of the staff members were not present in the laboratories but did teleworking. A total of 70% of the laboratories developed virtual meetings for the training of residents and junior pathologists. During the period of study, none of the staff members with confirmed COVID-19 became infected as a result of handling samples. Conclusions The COVID-19 pandemic has had a strong impact on most of the European pathology laboratories included in this study. Urgent implementation of several changes to the organization of most of these laboratories, notably to better harmonize biosafety procedures, was noted at the onset of the pandemic and maintained in the event of a new wave of infection occurring in Europe. Biosafety measures used in the first wave of the COVID-19 crisis were heterogeneous in 53 European pathology laboratories. A dramatic decrease of the workload in pathology laboratories was noted. No case of healthcare workers contaminated with SARS-CoV-2 associated with samples handling was identified.

Abstract
Adrenocortical carcinoma (ACC) is diagnosed using the histopathological Weiss score (WS), but remains clinically elusive unless it has metastasized or grows locally invasive. Previously, we proposed the objective IGF2 methylation score as diagnostic tool for ACC. This multicenter European cohort study validates these findings. Patient and tumor characteristics were obtained from adrenocortical tumor patients. DNA was isolated from frozen specimens, where after DMR2, CTCF3, and H19 were pyrosequenced. The predictive value of the methylation score for malignancy, defined by the WS or metastasis development, was assessed using receiver operating characteristic curves and logistic and Cox regression analyses. Seventy-six ACC patients and 118 patients with adrenocortical adenomas were included from seven centers. The methylation score and tumor size were independently associated with the pathological ACC diagnosis (OR 3.756 95% CI 2.224-6.343; OR 1.467 95% CI 1.202-1.792, respectively; Hosmer-Lemeshow test P = 0.903), with an area under the curve (AUC) of 0.957 (95% CI 0.930-0.984). The methylation score alone resulted in an AUC of 0.910 (95% CI 0.866-0.952). Cox regression analysis revealed that the methylation score, WS and tumor size predicted development of metastases in univariate analysis. In multivariate analysis, only the WS predicted development of metastasis (OR 1.682 95% CI 1.285-2.202; P < 0.001). In conclusion, we validated the high diagnostic accuracy of the IGF2 methylation score for diagnosing ACC in a multicenter European cohort study. Considering the known limitations of the WS, the objective IGF2 methylation score could potentially provide extra guidance on decisions on postoperative strategies in adrenocortical tumor patients.

Abstract
Three cases of connective tissue tumors causing hypophosphatemic osteomalacia are reported and the literature is reviewed. In two of our patients the tumors were completely excised with total disappearance of the symptoms. In one case a total excision was not possible and the symptoms of this patient have not completely disappeared. The substance responsible for the syndrome has not been identified yet, but probably interferes with vitamin D renal hy-droxylation, thus causing osteomalacia. As more than 30 per cent of cases of this condition have been reported in the last 5 years, it is suggested that these tumors are more frequent than previously believed.

Abstract
Carcinoembryonic antigen (CEA), though typically associated with malignant epithelial neoplasms, is known to be present at elevated levels even in the serum of normal individuals and of patients suffering from interstitial diseases of the lung. Few reports have addressed the question of the possible source of CEA immunoreactivity within the lung parenchyma. Two patients with elevated CEA serum levels were studied by immunohistochemistry on open lung biopsy specimens. Two different antibodies (one absorbed with non-specific cross-reacting antigen, NCA) were used. The results show that bronchiolar cells and type II pneumocytes are focally positive with both antibodies; the immunoreaction is preserved even after absorption with NCA. In agreement with experimental data on CEA synthesis in fetal bronchial cell lines, these findings indicate that interstitial lung disorders may induce abnormal CEA-like substance expression. In these cases, where no epithelial neoplasms subsequently develop, the cutoff level for CEA in serum should be raised. Bronchiolar and alveolar cells appear primarily responsible for CEA-like substance production.

Abstract
Malignant Pleural Mesothelioma (MPM) remains a relevant public health issue, and asbestos exposure is the most relevant risk factor. The incidence has considerably and constantly increased over the past two decades in the industrialized countries and is expected to peak in 2020-2025. In Italy, a standardized-rate incidence in 2011 among men was 3.5 and 1.25 per 100,000 in men and women, respectively, and wide differences are noted among different geographic areas. The disease remains challenging in terms of diagnosis, staging and treatment and an optimal strategy has not yet been clearly defined. The Third Italian Multidisciplinary Consensus Conference on Malignant Pleural Mesothelioma was held in Bari (Italy) in January 30-31, 2015. This Consensus has provided updated recommendations on the MPM management for health institutions, clinicians and patients.

Abstract
PURPOSE To evaluate if including nephrectomy in the standard surgical approach to stage II adrenocortical cancer (i.e., adrenalectomy) might modify oncologic outcome of patients. METHODS We performed a retrospective analysis involving 41 patients with stage II adrenocortical cancer (ACC) who had undergone radical surgery. Patients were divided into two groups according to the surgical procedure: group A = radical adrenalectomy alone, group AN = radical adrenalectomy + radical nephrectomy. Oncologic effectiveness of the procedures was tested comparing the recurrence-free and overall survival of patients of A vs AN groups. RESULTS The group A consisted of 25 patients and group AN of 16 patients. No differences were noted between the two groups in terms of demographic data and ACC characteristics. During follow-up, 15/25 (60 %) patients of group A vs 14/16 (87.5 %) patients of group AN experienced a recurrence, after a median of 36 months in group A and 10 months in group AN (p = 0.06); a significant impairment of renal function was recorded in patients of AN group with respect to those of group A. Finally, 13/25 (52 %) patients of group A and 10/16 (62.5 %) patients of group AN died due to ACC-related causes. No differences in survival times were noted (p = 0.3). CONCLUSION Our study suggests that adjunctive nephrectomy does not modify the oncologic results of adrenalectomy in the treatment of stage II ACC in terms of recurrence-free and overall survival. Thus, when there are no signs of ACC local invasion, surgeon should make every effort to preserve the kidney.

Abstract
Lung neuroendocrine tumors are catalogued in four categories by the World Health Organization (WHO 2004) classification. Its reproducibility and prognostic efficacy was disputed. The WHO 2010 classification of digestive neuroendocrine neoplasms is based on Ki67 proliferation assessment and proved prognostically effective. This study aims at comparing these two classifications and at defining a prognostic grading system for lung neuroendocrine tumors. The study included 399 patients who underwent surgery and with at least 1 year follow-up between 1989 and 2011. Data on 21 variables were collected, and performance of grading systems and their components was compared by Cox regression and multivariable analyses. All statistical tests were two-sided. At Cox analysis, WHO 2004 stratified patients into three major groups with statistically significant survival difference (typical carcinoid vs atypical carcinoid (AC), P=0.021; AC vs large-cell/small-cell lung neuroendocrine carcinomas, P<0.001). Optimal discrimination in three groups was observed by Ki67% (Ki67% cutoffs: G1 <4, G2 4-<25, G3 ≥25; G1 vs G2, P=0.021; and G2 vs G3, P≤0.001), mitotic count (G1 ≤2, G2 >2-47, G3 >47; G1 vs G2, P≤0.001; and G2 vs G3, P≤0.001), and presence of necrosis (G1 absent, G2 <10% of sample, G3 >10% of sample; G1 vs G2, P≤0.001; and G2 vs G3, P≤0.001) at uni and multivariable analyses. The combination of these three variables resulted in a simple and effective grading system. A three-tiers grading system based on Ki67 index, mitotic count, and necrosis with cutoffs specifically generated for lung neuroendocrine tumors is prognostically effective and accurate.

Abstract
This study aimed at challenging pulmonary large cell carcinoma (LLC) as tumor entity and defining different subgroups according to immunohistochemical and molecular features. Expression of markers specific for glandular (TTF-1, napsin A, cytokeratin 7), squamous cell (p40, p63, cytokeratins 5/6, desmocollin-3), and neuroendocrine (chromogranin, synaptophysin, CD56) differentiation was studied in 121 LCC across their entire histological spectrum also using direct sequencing for epidermal growth factor receptor (EGFR) and v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations and FISH analysis for ALK gene translocation. Survival was not investigated. All 47 large cell neuroendocrine carcinomas demonstrated a true neuroendocrine cell lineage, whereas all 24 basaloid and both 2 lymphoepithelioma-like carcinomas showed squamous cell markers. Eighteen out of 22 clear cell carcinomas had glandular differentiation, with KRAS mutations being present in 39 % of cases, whereas squamous cell differentiation was present in four cases. Eighteen out of 20 large cell carcinomas, not otherwise specified, had glandular differentiation upon immunohistochemistry, with an exon 21 L858R EGFR mutation in one (5 %) tumor, an exon 2 KRAS mutation in eight (40 %) tumors, and an ALK translocation in one (5 %) tumor, whereas two tumors positive for CK7 and CK5/6 and negative for all other markers were considered adenocarcinoma. All six LCC of rhabdoid type expressed TTF-1 and/or CK7, three of which also harbored KRAS mutations. When positive and negative immunohistochemical staining for these markers was combined, three subsets of LCC emerged exhibiting glandular, squamous, and neuroendocrine differentiation. Molecular alterations were restricted to tumors classified as adenocarcinoma. Stratifying LCC into specific categories using immunohistochemistry and molecular analysis may significantly impact on the choice of therapy.

Abstract
Axl is a receptor that induces proliferation, migration and invasion in cancer. In this study, we show that specific microRNAs (miRNAs) target the 3'-UTR of Axl. Luciferase-reporter assays with wild-type and deleted miR-34 and miR-199a/b seed sequences of Axl 3'-UTR confirmed the specificity of targeting. An inverse correlation between Axl protein and miR-34a expression in a panel of non-small cell lung cancer (NSCLC), colorectal cancer (CRC) and breast cancer (BRC) cell lines was observed, while miR-199a/b expression was completely suppressed. Pre-miR transfection inhibited in vitro migration and invasion and, in vivo, reduced the number of distant lung- or liver-metastases in a chorion-allantoic-membrane (CAM) assay. Moreover, methylation-specific PCR on bisulfite-converted DNA obtained from the cell lines showed that the miR-34a promoter methylation status was inversely correlated with its expression, and that miR-199a/b promoter regions were methylated in all cells tested. In a panel of NSCLC tissues (n=44), miR-34a and miR-199a/b were found to be downregulated and significantly co-expressed. A lower expression of all three miRs was significantly associated with squamous histotypes, and, in a preliminary series, NSCLC patients with miR-34a upregulation showed a positive association towards a longer survival. These results indicate that Axl receptor expression can be regulated by miR-34a and miR-199a/b, which are suppressed by promoter methylation in solid cancer cells.

Abstract
BACKGROUND The management of pulmonary neuroendocrine tumours (NETs), with special reference to clinically aggressive carcinoids and large-cell neuroendocrine carcinomas (LCNECs), is poorly standardised and data about somatostatin receptor (SSTR) expression or therapeutic guidelines for somatostatin analogue administration are still debated. MATERIALS AND METHODS A series of 218 lung NETs [24 metastatic typical carcinoids (TCs), 73 atypical carcinoids (ACs), 60 LCNECs and 61 surgically resected small-cell lung carcinomas] were investigated for SSTR types 2A and 3 tissue distribution using immunohistochemistry, in correlation with clinicopathologic parameters, outcome, scintigraphy and treatment. RESULTS SSTRs were heterogeneously distributed with a significant progressive decrease from low- to high-grade forms. SSTR type 2A was strikingly overexpressed in metastatic TCs as compared with ACs and clinically benign TCs. SSTR tissue immunolocalization correlated with octreotide scintigraphy in 20 of 28 cases. CONCLUSION The immunohistochemical determination of SSTRs, with special reference to low-grade/intermediate-grade tumours, may assist the clinical approach with somatostatin analogue-based diagnostic and therapeutic procedures in clinically aggressive pulmonary NETs.

Abstract
7508 Background: Pemetrexed has shown activity in malignant pleural mesothelioma (MPM) but scanty data are available on the expression of thymidylate synthase (TS), its most important molecular target. Methods: From a database of 75 non-surgical, chemotherapy-naive MPM patients from our Institution in the period 2004–2008, 50 (male/female: 37/13, median age: 65 years) met the selection criteria i.e. epithelial type, availability of thoracoscopic tissue and outcome data. Pemetrexed was administered as single agent (14/50) or in combination with cisplatin or carboplatin (36/50). Retrospectively TS protein expression levels were evaluated by immunohistochemistry and quantified with H-score method. In addition, mRNA extraction was performed in 23 micro-dissected tissues and TS relative levels quantified by RT-PCR. Survival probability was assessed by Kaplan-Meier method and results compared by log-rank test. Cox multivariate analysis for survival was performed adjusting for clinical-pathological variables. Results: Thirty-two patients had progressive disease and 24 had died at the time of the analysis. Median time to progression (TTP) and median survival time (MST) were 11.6 and 20.9 months, respectively. Median TS H-score value was 90 (5–240). No correlation were found with sex, age, PS, stage and chemotherapy regimen. Patients with high TS H-score (4th quartile) had a significantly shorter MST (13.3 vs 21.1 months, p<0.01) and showed a trend for shorter TTP (8.3 vs 11.9 months, p=0.07). Median TS mRNA level was 1.88 (1–3.7 unit-less ratio) and a significant correlation between mRNA and protein expression (RS=0.67, p<0.0001) was found. Patients with high TS mRNA levels (4th quartile) had significantly shorter TTP (8.7 vs 14.7 months, p=0.019) and MST (11.7 vs 24.7, p=0.018). Multivariate analysis for survival indicated that TS protein levels were an independent prognostic factor (HR=2.17; CI 1.04–4.54; p=0.038). Conclusions: TS (protein and mRNA) levels predict outcome of epithelial MPM patients treated with pemetrexed-based chemotherapy. TS quantification, if confirmed in larger prospective studies, could be used to select those patients more likely to respond to chemotherapy. [Table: see text]

Abstract
7521 Background: In non-small cell lung cancer (NSCLC) baseline thymidilate synthase (TS) levels are higher in squamous cell carcinoma (SCC) compared to adenocarcinoma (AC) and randomized clinical trials have shown a selective benefit for patients with non-squamous histology treated with pemetrexed, a TS-inhibiting agent. TS expression in undifferentiated large cell carcinoma (LCC) is unknown. Methods: TS expression at both mRNA (using tissue microdissection and qRT-PCR) and protein (through immunohistochemistry, IHC) levels was tested in 34 surgically resected LCC (stage I=20,II=6,IIIa=8) and compared with TS expression in surgical cases of SCC (n= 31) and AC (n=40). In addition other comparisons were made: a) TS protein expression with Ki-67 index; b) TS mRNA and E2F1 transcription factor mRNA; c) in all histotypes TS protein level with desmocollin-3 (DSC-3) immunostaining, a marker of squamous cell differentiation. TS expression level was assessed in a group of patients (n=22) with cytological diagnosis of NSCLC-NOS (not otherwise specified) and compared with TS data in tissue specimens obtained through subsequent bronchial biopsy or surgical resection. Results: Significantly higher median TS levels in LCC compared to AC (p<0.001 for both mRNA and protein values) and SCC compared to AC (p=0.002 mRNA, p<0.001 protein) were detected. A strong correlation between TS mRNA and protein levels were found (p<0.001) in SCC and AC, but not in LCC. TS and both Ki-67 and E2F1 were significantly correlated in AC and SCC (p=0.003 and p=0.05, respectively), but in LCC no correlation was found. In LCC, significantly higher TS levels were observed in DSC3-positive compared to DSC3-negative tumors (p=0.02). A significant correlation between TS IHC scores in matched cytological and corresponding tissue specimens was observed (p<0.001). Conclusions: This study demonstrates and confirms the: a) differential expression of TS among the NSCLC histotypes; b) lack of DSC-3 immunoreactivity in LCC is associated with lower TS expression; c) assessment of TS by IHC in cytological specimens correlates with the corresponding tissue TS expression.

Abstract
e21509 Background: Primary sarcomas of the lungs and mediastinum are rare and few data are reported on treatment and results of therapy. Methods: We reviewed our experience from 1980 and 2008 including 31 patients (pts). Pts characteristics: median age 41 (19–80 y), male/female 19/12; symptoms at diagnosis: dyspnoea (42%), chest and shoulder pain (39%), cough (35%), hemophtoae (13%), discomfort (10%). 4 pts had a previous history of mediastinal radiation for Hodgkin's and non-Hodgkin's linfomas. 5 mediastinal tumours were located as follows: 2 in anterior part, 1 in posterior and 2 in the middle (sarcomas of the heart). 26 lung sarcomas presented as a singular mass in 23 cases and as a metastatic disease in 3. Results: In 20/31 cases the tumour was immediately resected (3 mediastinal masses and 17 lung sarcomas). In 8/31 cases only biopsy was possible. FNA was done in 25 pts. Neoadjuvant chemotherapy was performed in 4 cases (3 resected). Resection was complete in 11/23 cases and in 12/23 incomplete. The histology were: peripheral nerve tumour 7, leiomyosarcoma 4, MFH 2, fibrosarcoma 2, liposarcoma 1, angiosarcoma 2, undifferentiated sarcoma 1, solitary fibrous tumour 2, rhabdomyosarcoma 2, synovialsarcoma 2, pulmonary artery sarcoma 1, pleuropolmonary blastoma 1, malignant hemangiopericytoma 1, mixoid chondrosarcoma 1, ectopic osteosarcoma 1, aggressive fibromatosis 1. Only 4 pts received neoadjuvant chemotherapy, 11 adjuvant CT, 5 exclusive CT + RT for inoperable disease. Radiotherapy was completed in 26 pts (21 adjuvant). Local relapse or metastatic progression were recorded in 16/23 pts and 12 received one or more lines of palliative CT. Data about survival are disposable only for the more recently recorded pts (1998–2008: 17 pts). Of these only 8 are alive (2 with disease). Volume of disease, complete resection and grading are the dominant prognostic factors. Conclusions: Primary sarcomas of the lungs and mediastinum have a very severe prognosis. Surgical resection is the fundamental therapy, but in the future the role of neoadjuvant CT will increase. No significant financial relationships to disclose.

Abstract
Somatostatin (SS) and its synthetic analogs have a role in the treatment of neuroendocrine tumours both in terms of symptoms control and antiproliferative activities. These effects are mediated by five SS receptors, widely expressed in both human neuroendocrine and non-neuroendocrine tumours, which were demonstrated to be diagnostically and therapeutically valuable targets. Cortistatin (CST), a brain cortex peptide, partially homologous to SS and having similar functions is also expressed in peripheral tissues and tumours. CST binds all SS receptors, and, differently from SS, also the ghrelin receptor GHSR1a and the CST specific receptor MrgX2. The expression profile of CST is mostly restricted to neuroendocrine tumours (gastrointestinal, pancreas, lung, parathyroid, thyroid, adrenal). In these tumours, CST probably acts via the SS or ghrelin receptor, the MrgX2 receptor being absent. Thus, in comparison to SS analogs, CST synthetic analogs may represent additional diagnostic/therapeutic tools in those tumours expressing the receptors for SS, for ghrelin or for both peptides.

Abstract
2526 Background: Platinum/etoposide is a commonly used regimen both in limited (LS) and extensive stage (ES) small-cell lung cancer (SCLC). The study was aimed at testing retrospectively the predictive role of mRNA quantification of genes correlated to platinum/etoposide therapy: ERCC1, RRM1 and TOPOIIa. Methods: Total RNA was extracted from microdissected sections of 103 formalin-fixed, paraffin embedded bronchial biopsies. Relative quantification for ERCC1, RRM1 and TOPOIIa and an internal reference gene (β- Actin) was performed by Real-Time PCR using intron-spanning primers. ERCC1 expression was also evaluated by immunohistochemistry using a semi-quantitative score. Results: Eighty-five samples (83%) were successfully amplified. Overall median survival (MS) was 9.9 months, 45 patients had LS (MS=13.1 months) and 40 had ES (MS=7.1 months). Fifty-six (65%) had an objective (complete or partial) response to treatment. Immunohistochemical staining of ERCC1 evidenced a positivity in 2 out of 85 patients with no correlation with clinico-pathological factors. By contrast, a gene expression level was detectable in all samples and a significant correlation between ERCC1 and RRM1 levels (Rs=0.34, p=0.0011) was found. By segregating patients according to response to treatment, it was found that lower TOPOIIa expression was associated to a better response in LS patients (p=0.025) and, more interestingly, those who had a complete response had low TOPOIIa levels than both partial and non-responsive patients (p=0.015). By adopting cut-offs according to median values, univariate analysis of survival by Kaplan-Meier method showed that LS patients with low ERCC1 had a significantly longer survival (MS 14.9 vs. 9.9 months, p=0.012), while RRM1 and TOPOIIa levels showed no influence on outcome. In multivariate analysis, ERCC1 was an independent prognostic factor for survival of LS patients, together with PS and response to therapy. No significant role was found for ERCC1, RRM1 and TOPOIIa in patients with ES. Conclusions: ERCC1 and TOPOIIa represent reliable candidate markers in predicting clinical outcome and response to treatment in LS SCLC patients, who may benefit from a better individualized therapy.

Abstract
Adrenal cysts are infrequently observed, since less than 500 cases have been reported in Western literature. Adrenal cysts are conventionally divided into four categories: epithelial, parasitic, endothelial, and hemorrhagic. They are characterized by different etiological and pathological features. Some authors suggest that endothelial and hemorrhagic cysts are related and may represent a spectrum of lesions. We report herein the case of an adrenal hemorrhagic pseudocyst that simulated adrenocortical cancer and argue on the clinical clues for a differential diagnosis with other adrenal tumors.

Abstract
Neuroendocrine tumors of the lung are carcinomas characterized by different impact on the patients' prognosis, ranging from relatively indolent, low- to intermediate-grade neoplasms with longer life expectation (i.e., typical and atypical carcinoids) to very aggressive and poorly differentiated neoplasms with dismal prognosis (i.e., large cell neuroendocrine carcinoma and small cell lung cancer). The standard treatment of typical or atypical carcinoids is the complete surgical resection, whereas the role of radio-chemotherapy in a multimodality treatment or for palliation remains controversial. Conversely, high-grade neuroendocrine carcinomas are in primis treated by aggressive combination chemotherapy, deserving surgical resection for uncommon low-stage tumors. Since evidence has been accumulated that neuroendocrine tumors of the lung are supplied with a wide array of peptide receptors detectable on cell membranes by immunohistochemical methods, innovative strategies for diagnosis and radiometabolic therapy have been devised to target these molecules for the correct clinical management of the patients. In this paper, the structural and functional aspects and the clinical applications of the detection of several peptide receptors in pulmonary neuroendocrine tumors will be reviewed, including somatostatin receptors, vasoactive intestinal peptide/pituitary adenylate cyclase activating peptide family receptors, cholecystokinin /gastrin receptors, bombesin/gastrin releasing peptide receptors, neurotensin receptors, substance P receptors, neuroepeptide Y receptors, calcitonin/calcitonin gene-related peptide receptors, atrial natriuretic peptide receptors, glucagon-like-peptide-1 receptors, oxytocin receptors and endothelin receptors. Only a detailed knowledge of the peptide receptor distribution in these tumor types, especially in uncommon neoplasms such as atypical carcinoids and large cell neuroendocrine carcinomas, is pivotal for planning the most adequate interventions for the patients' diagnosis and therapy.

Abstract
BACKGROUND Pivotal studies indicate a role of excision repair cross-complementation 1 (ERCC1) gene and ribonucleotide reductase M1 (RRM1) gene in conferring a differential sensitivity to cytotoxic chemotherapy and epidermal growth factor receptor (EGFR) gene has been recently extensively investigated in non-small-cell lung cancer (NSCLC). DESIGN Formalin-fixed, paraffin-embedded bronchoscopic/fine needle aspiration biopsies obtained from 70 patients with advanced NSCLC were retrospectively collected to investigate the expression level of ERCC1, RRM1 and EGFR by real-time PCR. Sufficient amounts of messenger RNA (mRNA) were successfully extracted from 61 (87%) specimens, reverse transcribed and amplified with intron-spanning primers. Forty-one patients had stage IV disease and 43 received cisplatin/gemcitabine chemotherapy. RESULTS A strong correlation between ERCC1 and RRM1 mRNA levels (r(s) = 0.624, P < 0.0001) was found. Median survival time in patients with low ERCC1 was significantly longer (17.3 versus 10.9, P = 0.0032 log-rank test) as well as in patients with low RRM1 (13.9 versus 10.9, P = 0.0390 log-rank test). Concomitant low expression levels of ERCC1 and RRM1 (n = 33) were predictive of a better outcome (14.9 versus 10.0, P = 0.0345 log-rank test). Among cisplatin-treated patients, a low ERCC1 level was highly predictive of a longer survival (23.0 versus 12.4, P = 0.0001 log-rank test). No correlation between gene expression levels and histology was reported. No significant correlation between EGFR expression level and survival was found. At multivariate analysis, performance status, response to chemotherapy, presence of weight loss and ERCC1 were independent prognostic factors for survival. CONCLUSIONS This retrospective study further validates ERCC1 and RRM1 genes as reliable candidates for customized chemotherapy and shows a higher impact on the survival of NSCLC patients treated with cisplatin/gemcitabine for ERCC1. Prospective pharmacogenomic studies represent a research priority in early and advanced NSCLC.

Abstract
Ghrelin, a natural GH secretagogue (GHS) acylated peptide, and cortistatin (CST), a natural SRIF-like peptide, interfere with neoplastic growth in different cancers. We tested forty-one lung carcinomas and the H345 small cell lung carcinoma (SCLC) cell line by RT-PCR to investigate the presence of ghrelin and CST and related receptors, including type 1a GHS receptor (GHS-R1a), all SRIF-receptor subtypes (sst 1-5) and MRGX2. Moreover, the presence of ghrelin and CST peptides was studied in both tumors and H345 cells. Ghrelin and CST mRNA were present in the majority of tested tumors, but ghrelin and CST proteins were revealed only in tumors with a neuroendocrine phenotype. All the receptors mRNA had a heterogeneous expression without correlation between ghrelin (or CST) and their receptor distribution. All the transcripts, but not GHS-R1a, were expressed in H345 cells. However, ghrelin and desacyl ghrelin induced in vitro a dose-dependent inhibition on the H345 cell proliferation and increased apoptosis. Conversely, neither CST nor SRIF affected H345 cell growth, despite the presence of their specific receptors. The anti-proliferative and the pro-apoptotic effects of ghrelin were consistent with binding experiments on H345 cell, where either acylated or des-acylated ghrelin recognized a common binding site. In conclusion, the present study indicates that: a) ghrelin and CST mRNAs are expressed in lung cancers, although some neuroendocrine tumors contain detectable amounts of the peptides; b) GHSR-1a mRNA is present exclusively in neuroendocrine tumors, whereas MRGX2 mRNA (but not peptide) is expressed in all histological types; c) both ghrelin forms inhibit H345 cell proliferation, both directly and enhancing apoptosis, despite the absence of GHS-R1a, whereas CST and its receptors do not interfere with cell growth.

Abstract
BACKGROUND The down regulation of protein p27(kip1) (p27) in most cases of thyroid cancer has relevant diagnostic and prognostic implications. However, the oxyphilic (Hurthle cell) variant of follicular thyroid carcinoma expresses more p27 than benign oxyphilic lesions do. AIM To evaluate the mechanism underlying this difference in expression of p27. METHODS Because high levels of cyclin D3 lead to p27 accumulation in cell lines and clinical samples of thyroid cancer, the immunocytochemical pattern of cyclin D3 in oxyphilic (n = 47) and non-oxyphilic (n = 70) thyroid neoplasms was investigated. RESULTS In the whole study sample, there was a significant correlation between p27 and cyclin D3 expression (Spearman's r: 0.64; p<0.001). The expression of cyclin D3 and p27 was significantly higher in the oxyphilic variant of follicular carcinomas than in non-oxyphilic carcinomas (p<0.001). In the former, cyclin D3 overexpression and p27 accumulation were observed in a median of 75% and 55% of cells, respectively. In co-immunoprecipitation experiments, the level of p27-bound cyclin D3 was much higher in oxyphilic neoplasias than in normal thyroids and other thyroid tumours. CONCLUSION These results show that increased p27 expression in the oxyphilic (Hurthle cell) variant of follicular thyroid carcinoma results from cyclin D3 overexpression.

Abstract
14534 Background: Adrenocortical carcinoma (ACC) is a very rare disease which account for no more than 0.2% of all malignancies, and its differential diagnosis from adrenocortical adenomas (ACA) is based on the application of different scoring systems, which, however, lack a sensitivity and specificity of 100%. Little is known on the mechanisms leading to the malignant phenotype in adrenocortical tumors; among alternative mechanisms, metalloproteinases (MMPs) have been demonstrated in solid tumors, including endocrine ones, to be implicated in malignant progression and metastatization. Our aim was to investigate metalloproteinase 2 (MMP2) expression in adrenocortical tumors. Methods: A series of 33 ACC and 23 ACA was retrospectively collected from a large series of adrenocortical lesions, and the diagnosis was reviewed independently by three investigators (MV, EB, MP) according to the Weiss histological criteria. MMP2 was determined by immunohistochemistry and the results scored by semi-quantitative analysis, based on the intensity of the staining and the percentage of tumor cells positive. Immunohistochemical results were compared to clinico-pathological parameters, such as sex, age, hormonal secretion, and outcome. Results: MMP2 expression was detected in 1/23 ACA (4%), and in 25/33 ACC (76%) (X-square test p < 0.001). MMP2 immunohistochemical pattern in ACC was focal to moderate to strong in 10, 12 and 3 cases, respectively. In addition, moderate to strong MMP2 expression, as compared to low or negative immunostaining, correlated with shorter disease-free survival (p = 0.012) and poor outcome (p = 0.07). No correlation were found comparing MMP2 expression and other clinico-pathological parameters. Conclusions: As reported in a variety of solid tumors, our data indicates a possible role of MMP2 in the malignant evolution of adrenocortical tumors, and its immunohistochemical localization may be a potential useful tool in the differential diagnosis of benign versus malignant adrenocortical lesions. In addition, a strong immunohistochemical MMP2 expression seems to be related to a poor prognosis in ACC. No significant financial relationships to disclose.

Abstract
10030 Background: Pivotal studies indicate a role of excision repair cross-complementation 1 (ERCC1) and ribonucleotide reductase M1 (RRM1) in conferring a differential sensitivity to cytotoxic chemotherapy and epidermal growth factor receptor (EGFR) has been recently deeply investigated in NSCLC. Methods: We retrospectively collected 70 formalin-fixed paraffin-embedded (FFPE) bronchoscopic/fine needle aspiration biopsies of NSCLC to investigate the expression levels of ERCC1, RRM1 and EGFR by Real-Time PCR (Lord R et al. Clin Cancer Research 2002, 8:2286–91). Results were correlated with survival using the Kaplan-Meier method. Results: Sixty-one (87%) specimens were successfully amplified. Median age was 62 years (range 26–75), male/ female ratio 44/17, stage III/IV 20/41; 43 patients received cisplatin-based chemotherapy; overall median survival (MS) was 13.3 months over a median follow-up time of 45 months. ERCC1 expression level ranged from 0.70 to 15.12, RRM1 0.60–17.82. By adopting cut-off values according to median expression levels, we found a strong correlation between ERCC1 and RRM1 mRNA levels (r=0.410; p<0.001). MS in patients with low ERCC1 was significantly longer (16.9 vs 11.3 months, p<0.006) as well as in patients with low RRM1 (13.9 vs 10.9 months, p<0.03). Concomitant high expression levels of ERCC1 and RRM1 (n=26) are predictive of a worse outcome (13.9 vs 10.9 months, p<0.05). Among patients treated with cisplatin-based regimens, low ERCC1 levels were also predictive of a significantly longer MS (23.0 vs 11.6 months, p<0.002). A lower median ERCC1 level (3.2 vs 4.7) and a correlation with a better outcome were also observed in females vs males. No correlation between gene expression levels and histology was reported. No significant correlation between EGFR expression levels (range 0.5–85.8) and survival was found, even when different cut-off values were tested. Conclusions: This retrospective study further validates ERCC1 and RRM1 as good candidates genes to customize chemotherapy. Prospective studies based on the selection of patients according to genes expression levels are a research priority in early and advanced stages of NSCLC. [Table: see text]

Abstract
7049 Background: Bone metastases (BM) in non small cell lung cancer (NSCLC) may be present at diagnosis or develop in the follow up, are associated with a worse prognosis, and currently there are no chemical or biological markers predicting their clinical onset. Methods: Thirty cases of resected NSCLC which subsequently develop BM (group A - mean follow up time 27.2 months) were matched for several clinico-pathological parameters (including age, sex, stage of the disease, histology, differentiation grade, adjuvant therapy) to 30 cases of resected NSCLC without any metastases (group B - mean follow up time 75.1 months) and 26 resected NSCLC with non-bone metastatic (group C - mean follow up 21.1 months). Primary tumor samples were investigated by immunohistochemistry for 10 markers previously recognized to be involved in bone resorption or metastatization process (cathepsin K, bone sialoprotein [BSP], VEGF, MMP-2, p53, RECK, TIMP-1, CD-117, Ki-67 and TRAcP). For statistical analysis the intensity of the staining was assessed by a semi-quantitative score (0, <10%, 10–50%, >50% +ve tumor cells). Differences among groups were estimated by X-square test, whereas the prognostic impact of clinico-pathological parameters and markers expression was evaluated by univariate and multivariate analyses. Results: Among the different markers investigated, BSP was strongly associated to bone dissemination (p < 0.001) and, independently, to poor outcome (p = 0.02 by Mantel-Cox test). None of the other markers was differentially expressed within the groups or demonstrated a prognostic impact, both in terms of overall survival and of time interval to metastases. Based on these findings, the prevalence of BSP in NSCLC was further estimated in a large series of 120 resected lung carcinomas (M:F ratio 3:1; mean age 67 years; adenocarcinomas 55%, squamous cell carcinoma 39%, others 6%; stages: I 54%, II 17%, III 29%). BSP prevalence reached 40%, without any statistically significant difference according to histotype or other clinico-pathological parameters. Conclusions: BSP protein expression in resected NSCLC strongly predicts bone dissemination, and may therefore be useful in selecting patients for treatments targeted to inhibit bone metastatic spread.

Abstract
13505 Background: Autocrine TGFa in CRC cells regulates cell adhesion via p70S6K phosphorylation in in vitro studies. The aim was to evaluate whether TGFa expression might be correlated with a higher metastatic behavior in vivo. Methods: 101 primitive CRC tumor samples with paraffin blocks available were retrospectively collected. All the specimens were immunohistochemically evaluated for EGFR clone 2–18C9 (Dako), and TGFa clone 213–4 (Calciochem) expression. A score of 0 to 3 was assigned according to staining intensity and extension. EGFR was also evaluated in randomly selected specimens with clone 111.6 (Neomarks) in 81 cases and clone 31G7 (Zymed) in 28 cases. Selected samples were stained for downstream signalling molecules STAT, p-akt, p-MAP kinase, mTor, p-mTor and p70S6K. Patients were divided into 2 groups according to tumor stage at diagnosis: group A stage II-III (51 pts); group B stage IV (50 pts). Results: EGFR clone 2–18C9 reacted in 68/101 (67.3%) cases. Positivity rates and correlation coefficients were: clone 111.6 42/81 (51.9%), r=0.54 (p<0.01); clone 31G7 20/28 (71.4%), r=0.76 (p<0.0001). TGFa was expressed in 79/101 (78.2%) cases. EGFR and TGFa diffuse staining (score 2, 3) was recorded in 14/51 (27.5%) and 18/51 (35.3%) patients in group A, and 26/50 (52.0%) and 27/50 (54.0%) in group B (p=0.01 and p=0.06). EGFR and TGFa coexpression was evident in 23/51 (45.1%) in group A and in 34/50 (68.0%) in group B (p=0.02). No difference in downstream signaling molecule expression was evident between the 2 groups. A positive correlation trend was recorded for p70S6K which was expressed in 8/20 (40%) and in 8/12 (66.7%) samples of group A and B (p=0.15). Conclusions: EGFR, TGFa and p70S6K expression was more common in patients with advanced stage at diagnosis confirming in vitro data. EGFR scores obtained with commercial antibodies from Zymed and Dako had a significant correlation. No significant financial relationships to disclose.
