Abstract
BACKGROUND Cognitive changes in Huntington's disease (HD) precede motor manifestations. ENROLL-HD platform includes four cognitive measures of information processing speed (IPS). Our group is eager to seek clinical markers in the life stage that is as close as possible to the age of onset (ie, the so called prodromal HD phase) because this is the best time for therapeutic interventions. OBJECTIVES Our study aimed to test whether cognitive scores in prodromal ENROLL-HD mutation carriers show the potential to predict the severity of motor and behavioral changes once HD became fully manifested. METHODS From the global ENROLL-HD cohort of 21,343 participants, we first selected a premanifest Cohort#1 (ie, subjects with Total Motor Score (TMS) <10 and Diagnostic Confidence Level (DCL) <4, N = 1.222). From this cohort, we then focused on a prodromal Cohort#2 of subjects who were ascertained to phenoconvert into manifest HD at follow-up visits (ie, subjects from 6 ≤ TMS≤9 and DCL <4 to TMS≥10 and DCL = 4, n = 206). RESULTS The main results of our study showed that low IPS before phenoconversion in Cohort#2 predicted the severity of motor and behavioral manifestations. By combining the four IPS cognitive measures (eg, the Categorical Verbal Fluency Test; Stroop Color Naming Test; Stroop Word Reading; Symbol Digit Modalities Test), we generated a Composite Cognition Score (CCS). The lower the CCS score the higher the TMS and the apathy scores in the same longitudinally followed-up patients after phenoconversion. CONCLUSIONS CCS might represent a clinical instrument to predict the prognosis of mutation carriers who are close to manifesting HD.

Abstract
BACKGROUND This study is aimed at assessing the clinimetric properties and feasibility of the Italian version of the Montreal Cognitive Assessment (MoCA) in patients with Huntington's disease (HD). METHODS N = 39 motor-manifest HD patients, N = 74 Parkinson's disease (PD) patients and N = 92 matched HCs were administered the MoCA. HD patients further underwent the Unified Huntington's Disease Rating Scale (UHDRS), self-report questionnaires for anxiety and depression and a battery of first- and second-level cognitive tests. Construct validity was tested against cognitive and behavioural/psychiatric measures, whereas ecological validity against motor-functional subscales of the UHDRS. Sensitivity to disease severity was tested, via a logistic regression, by exploring whether the MoCA discriminated between patients in Shoulson-Fahn stage ≤ 2 vs. > 2. The same analysis was employed to test its ability to discriminate HD patients from HCs and PD patients. RESULTS The MoCA converged towards cognitive and behavioural measures but diverged from psychiatric ones, being also associated with motor/functional measures from the UHDRS. In identifying patients with cognitive impairment, adjusted MoCA scores were highly accurate (AUC = .92), yielding optimal diagnostics at the cut-off of < 19.945 (J = .78). The MoCA was able to discriminate patients in the middle-to-advanced from those in the early-to-middle stages of the disease (p = .037), as well as to differentiate HD patients from both HCs (p < .001) and PD patients (p < .001). CONCLUSIONS The MoCA is a valid, diagnostically sound and feasible cognitive screener in motor-manifest HD patients, whose adoption is thus encouraged in clinical practice and research.

Abstract
INTRODUCTION Multiple sclerosis neuropsychological questionnaire (MSNQ) is a brief questionnaire useful for screening patient's and informant's self-perception of cognitive dysfunctions in daily life activities. Our study aims to evaluate the MSNQ validity in Huntington's disease (HD) mutation carriers and to correlate MSNQ scores with neurological, cognitive, and behavioral variables. METHODS The study was conducted on a sample of 107 subjects from presymptomatic to the middle stage of HD recruited at LIRH Foundation and C.S.S. Mendel Institute in Rome. Unified Huntington's Disease Rating Scale (UHDRS), an internationally standardized and validated scale, was used to evaluate motor, functional cognitive, and behavioral domains. RESULTS Our results showed that in HD subjects, MSNQ has a unidimensional factor structure. Correlational analyses indicated a good correlation between the MSNQ-patient version (MSNQ-p) and clinical variables, specifically with cognitive dysfunction and behavioral alterations. Moreover, higher scores in MSNQ-p were associated with higher motor disease and functional impairment showing that patients in advanced stage of HD perceive a greater cognitive impairment. These results confirm the questionnaire's reliability. CONCLUSIONS The present study demonstrates the validity and adaptability of MSNQ in the HD population proposing it as a cognitive tool during routine clinical follow-ups, although further research is needed to determine an optimal cut-off score for this measure.

Abstract
BACKGROUND This study aimed at assessing the diagnostic properties of the Frontal Assessment Battery (FAB) as to its capability to (1) discriminate healthy controls (HCs) from patients with Huntington's disease (HD) and (2) identify cognitive impairment in this population. MATERIALS Thirty-eight consecutive HD patients were compared to 73 HCs on the FAB. Patients further underwent the Montreal Cognitive Assessment (MoCA) and the Unified Huntington's Disease Rating Scale (UHDRS). Receiver-operating characteristics (ROC) analyses were run to assess both intrinsic-i.e., sensitivity (Se) and specificity (Sp), and post-test diagnostics, positive and negative predictive values (PPV; NPV) and likelihood ratios (LR+; LR-), of the FAB both in a case-control setting and to identify, within the patient cohort, cognitive impairment (operationalized as a below-cut-off MoCA score). In patients, its diagnostic accuracy was also compared to that of the cognitive section of the UHDRS (UHDRS-II). RESULTS The FAB and UHDRS-II were completed by 100 and 89.5% of patients, respectively. The FAB showed optimal case-control discrimination accuracy (AUC = 0.86-0.88) and diagnostic properties (Se = 0.68-0.74; Sp = 0.88-0.9; PPV = 0.74-0.8; NPV = 0.84-0.87; LR+ = 5.6-7.68; LR- = 0.36-0.29), performing even better (AUC = 0.9-0.91) at identifying cognitive impairment among patients (Se = 0.73-1; Sp = 0.86-0.71; PPV = 0.79-0.71; NPV = 0.82-1; LR+ =5.13-3.5; LR- = 0.31-0) and comparably to the UHDRS-II (89% vs. 85% of accuracy, respectively; p = 0.46). DISCUSSION In HD patients, the FAB is highly feasible for cognitive screening aims, being also featured by optimal intrinsic/post-test diagnostics within both case-control and case-finding settings.

Abstract
(1) Background: Sleep patterns are frequently disrupted in neurodegenerative disorders such as Huntington disease (HD); however, they are still poorly understood, especially their association with clinic features. Our study aimed to explore potential correlations between sleep features and motor, cognitive, behavioural and functional changes in manifest HD subjects. (2) Methods: We enrolled 42 patients who were assessed by the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) questionnaires; clinical features were evaluated by the validated ENROLL-HD platform assay, including the Unified Huntington’s Disease Rating Scale (UHDRS) and the Problem Behaviours Assessment Short Form (PBA-s). (3) Results: We found a significant association between the patients’ perception of sleep abnormalities and scores of impaired independence, cognitive and motor performances. Specifically, sleep efficiency (PSQI—C4 subscores) and the use of sleep medications (PSQI—C6 subscores) seem to be more frequently associated with the severity of the disease progression. (4) Conclusion: sleep abnormalities represent an important part of the HD clinical profile and can impair patients’ quality of life by affecting their level of independence, cognition performance and mental well-being.

Abstract
We focused on Cognitive Reserve (CR) in patients with early Huntington Disease (HD) and investigated whether clinical outcomes might be influenced by lifetime intellectual enrichment over time. CR was evaluated by means of the Cognitive Reserve Index questionnaire (CRIq), an internationally validated scale which includes three sections: education, working activity, and leisure time. The clinical HD variables were quantified at three different time points (baseline-t0, 1 year follow up-t1 and 2 years follow up-t2) as per the Unified Huntington’s Disease Rating Scale (UHDRS), an internationally standardized and validated scale including motor, cognitive, functional and behavioral assays. Our sample consisted of 75 early manifest patients, withclinical stage scored according to the Total Functional Capacity (TFC) scale. Our correlational analysis highlighted a significant inverse association between CRIq leisure time (CRIq_LA) and longitudinal functional impairment (namely, the differential TFC score between t2 and t0 or ΔTFC) (p < 0.05), and the multidimensional progression of HD as measured by the composite UHDRS (cUHDRS, p < 0.01). CRIq_LA was significantly and positively associated with better cognitive performances at all time points (p < 0.05). Our results suggest that higher is the CRIq_LA, milder is the progression of HD in terms of functional, multidimensional and cognitive outcome.

Abstract
INTRODUCTION Behavioral and cognitive changes can be observed across all Huntington disease (HD) stages. Our multicenter and retrospective study investigated the association between cognitive and behavioral scale scores in manifest HD, at three different yearly timepoints. METHODS We analyzed cognitive and behavioral domains by the Unified Huntington's Disease Rating Scale (UHDRS) and by the Problem Behaviors Assessment Short Form (PBA-s), at three different yearly times of life (t0 or baseline, t1 after one year, t2 after two years), in 97 patients with manifest HD (mean age 48.62 ± 13.1), from three ENROLL-HD Centers. In order to test the disease progression, we also examined patients' motor and functional changes by the UHDRS, overtime. RESULTS The severity of apathy and of perseveration/obsession was associated with the severity of the cognitive decline (p < .0001), regardless of the yearly timepoint. The score of irritability significantly and positively correlated with perseveration errors in the verbal fluency test at t0 (r = .34; p = .001), while the psychosis significantly and negatively correlated with the information processing speed at t0 (r = -.21; p = .038) and significantly and positively correlated with perseveration errors in the verbal fluency test at t1 (r = .35; p < .0001). The disease progression was confirmed by the significant worsening of the UHDRS-Total Motor Score (TMS) and of the UHDRS-Total Functional Capacity (TFC) scale score after two-year follow-up (p < .0001). CONCLUSION Although the progression of abnormal behavioral manifestations cannot be predicted in HD, the severity of apathy and perseveration/obsessions are significantly associated with the severity of the cognitive function impairment, thus contributing, together, to the disease development and to patients' loss of independence, in addition to the neurological manifestations. This cognitive-behavior pattern determines a common underlying deficit depending on a dysexecutive syndrome.

Abstract
BACKGROUND Adrenal lipid-poor adenomas (LPA) are defined by high unenhanced density (≥ 10 HU), and absolute and relative contrast medium washout > 60% and > 40%, respectively, at computerized tomography (CT). To date, no thorough histopathological characterization has been performed in those frequent lesions (one-third of adrenal adenomas). Our aim was to analyze the histopathological characteristics of adrenal LPA. METHODS Patients with LPA (n = 57) were selected among consecutive subjects referred for an adrenal incidentaloma or ACTH-independent Cushing syndrome. FluoroDeoxyGlucose-Positron Emission Tomography (FDG-PET) was performed in 37 patients. In patients treated by adrenalectomy (n = 17), Weiss score and Lin-Weiss-Bisceglia score (in tumors composed entirely or predominantly of oncocytes) were calculated. RESULTS Radiological parameters did not differ among patients with ACTH-independent Cushing syndrome (n = 6) and those with adrenal incidentalomas associated with primary aldosteronism (n = 2), autonomous cortisol secretion (n = 14), or non-functioning (n = 35). Patients treated by adrenalectomy had larger tumors (28.9 ± 11.2 vs 17.3 ± 8.4 mm, P < 0.001), higher CT unenhanced density (29.1 ± 11.0 vs 23.1 ± 9.0 HU, P = 0.043), and FDG-PET adrenal uptake (9.0 ± 6.4 vs 4.4 ± 2.3 SUV, P = 0.003) than non-operated ones. Oncocytic features > 75% of the tumor were detected in 12/17 cases (70.6%). Five of those showed borderline-malignant histopathological characteristics by Lin-Weiss-Bisceglia score. Among remaining non-oncocytic tumors, 1/5 had a Weiss score ≥ 3. Overall, 6/17 tumors (35.3%) had borderline-malignant potential. Radiological parameters were similar between patients with benign and borderline-malignant tumors. CONCLUSIONS Adrenal LPA are a heterogeneous group of tumors, mostly composed of oncocytomas. Up to 1/3 of those tumors may have a borderline-malignant potential at histopathology.

Abstract
A permanent cell line, BO-101, was derived from a classic vermian medulloblastoma in a 9-year-old child. This line grew in vitro in adherent cultures and grew in athymic mice as serially transplantable intracranial and subcutaneous xenografts. Intracranial neoplasms grew as masses of small cells, which focally showed large cells with intense immunoreactivity for desmin, myoglobin and α-striated actin. The rhabdomyoblastic nature of these cells was confirmed ultrastructurally. The primary neoplasm showed immunoreactivity for synaptophysin, neuron-specific enolase and vimentin. A large panel of monoclonal antibodies and antisera against neuronal and glial antigens failed to show glial and neuronal immunoreactivity in the cell culture and xenografts. Despite the marked genotypic and phenotypic differences, the original neoplasm and the cell line share a common chromosomal marker del (12) (p 13.1). The BO-101 line differs phenotypically and genotypically from previously established medulloblastoma cell lines and further supports the heterogeneous biologic proprieties of the cell populations that constitute these neoplasms.

Abstract
The silver staining of interphase nucleolar organizer regions (NORs) has been shown to have an important application in diagnostic histopathology for distinguishing some benign from malignant conditions. In this study, normal fetal and adult skeletal muscles and tissue from fetal and adult rhabdomyomas as well as rhabdomyosarcomas were stained with the silver method for NORs. The morphologic distribution of NORs in rhabdomyosarcomas was found to be very different from that in normal skeletal muscles. In addition, cases of rhabdomyoma were easily differentiated from rhabdomyosarcomas. Statistical analysis of data, from all cases, regarding the diameter of NORs and number per nucleus confirmed these observations.

Abstract
Evidence is mounting that the small bodies of our Solar System, such as comets and asteroids, have at least partially inherited their chemical composition from the first phases of the Solar System formation. It then appears that the molecular complexity of these small bodies is most likely related to the earliest stages of star formation. It is therefore important to characterize and to understand how the chemical evolution changes with solar-type protostellar evolution. We present here the Large Program "Astrochemical Surveys At IRAM" (ASAI). Its goal is to carry out unbiased millimeter line surveys between 80 and 272 GHz of a sample of ten template sources, which fully cover the first stages of the formation process of solar-type stars, from prestellar cores to the late protostellar phase. In this article, we present an overview of the surveys and results obtained from the analysis of the 3 mm band observations. The number of detected main isotopic species barely varies with the evolutionary stage and is found to be very similar to that of massive star-forming regions. The molecular content in O- and C- bearing species allows us to define two chemical classes of envelopes, whose composition is dominated by either a) a rich content in O-rich complex organic molecules, associated with hot corino sources, or b) a rich content in hydrocarbons, typical of Warm Carbon Chain Chemistry sources. Overall, a high chemical richness is found to be present already in the initial phases of solar-type star formation.

Abstract
CONTEXT C-cyanomethanimine (HNCHCN), existing in the two Z and E isomeric forms, is a key prebiotic molecule, but, so far, only the E isomer has been detected toward the massive star-forming region. Sagittarius B2(N) using transitions in the radio wavelength domain. AIMS With the aim of detecting HNCHCN in Sun-like-star forming regions, the laboratory investigation of its rotational spectrum has been extended to the millimeter-/submillimeter-wave (mm-/submm-) spectral window in which several unbiased spectral surveys have been already carried out. METHODS High-resolution laboratory measurements of the rotational spectrum of C-cyanomethanimine were carried out in the 100-420 GHz range using a frequency-modulation absorption spectrometer. We then searched for the C-cyanomethanimine spectral features in the mm-wave range using the high-sensitivity and unbiased spectral surveys obtained with the IRAM 30-m antenna in the ASAI context, the earliest stages of star formation from starless to evolved Class I objects being sampled. RESULTS For both the Z and E isomers, the spectroscopic work has led to an improved and extended knowledge of the spectroscopic parameters, thus providing accurate predictions of the rotational signatures up to ~700 GHz. So far, no C-cyanomethanimine emission has been detected toward the ASAI targets, and upper limits of the column density of ~ 1011-1012 cm-2 could only be derived. Consequently, the C-cyanomethanimine abundances have to be less than a few 10-10 for starless and hot-corinos. A less stringent constraint, ≤ 10-9, is obtained for shocks sites. CONCLUSIONS The combination of the upper limits of the abundances of C-cyanomethanimine together with accurate laboratory frequencies up to ~ 700 GHz poses the basis for future higher sensitivity searches around Sun-like-star forming regions. For compact (typically less than 1″) and chemically enriched sources such as hot-corinos, the use of interferometers as NOEMA and ALMA in their extended configurations are clearly needed.

Abstract
This multicenter case-controlled pilot study evaluated myocardial inflammatory burden (IB) and phenotype in endomyocardial biopsies (EMBs) with and without pathologic antibody-mediated rejection (pAMR). Sixty-five EMBs from five European heart transplant centers were centrally reviewed as positive (grade 2, n = 28), suspicious (grade 1, n = 7) or negative (n = 30) for pAMR. Absolute counts of total, intravascular (IV) and extravascular (EV) immunophenotyped mononuclear cells were correlated with pAMR grade, capillary C4d deposition, donor specific antibody (DSA) status and acute cellular rejection (ACR). In pAMR+ biopsies, equivalent number of IV CD3+ T lymphocytes (23 ± 4/0.225 mm(2) ) and CD68+ macrophages (21 ± 4/0.225 mm(2) ) were seen. IB and cell phenotype correlated with pAMR grade, C4d positivity and DSA positivity (p < 0.0001). High numbers of IV T lymphocytes were associated with low grade ACR (p = 0.002). In late-occurring AMR EV plasma cells occurring in 34% of pAMR+ EMBs were associated with higher IB. The IB in AMR correlated with pAMR+, C4d positivity and DSA positivity. In pAMR+ equivalent numbers of IV T lymphocytes and macrophages were found. The presence of plasma cells was associated with a higher IB and occurrence of pAMR late after transplantation.

Abstract
INTRODUCTION DTC patients having detectable Tg and negative post-therapeutic (131)I-WBS have to be investigated by different imaging techniques to detect metastases. PURPOSE Comparison of neck US, CT and [18F]-FDG PET scan. METHODS In 49 DTC patients with biochemical disease, neck was examined by US, CT and [18F]-FDG PET. FNA was performed and Tg was determined by FNA-Tg in selected cases of suspicious lymph nodes. Thorax was examined by CT and PET. Serum Tg was measured on LT4 therapy (basal Tg) and after the stimulation with recombinant human TSH (peak Tg). RESULTS A thyroid remnant was seen by US, CT and PET in eight patients; recurrences were seen by US, CT and PET in six, five and five patients, respectively. Two metastatic nodes were identified by US and CT but not by PET. Lung micronodules were detected by CT in 7/49 (14.3 %) patients and by FDG PET in three of them. Basal Tg ranged from 0.5-1,725 ng/ml while peak Tg ranged from 0.5 to 2,135 ng/ml: the distribution between positive and negative patients was similar. Bone scan was negative in all cases. CONCLUSIONS In DTC patients with detectable Tg and negative I-131 post-therapy WBS, imaging examination revealed remnant or metastases in 43 % of cases. Remnant and recurrences were equally detected by the three techniques; US was better than [18F]-FDG PET for lymph node metastases since this latter method can give false both positive and negative results; chest examination is best made by CT versus FDG PET due to its higher spatial resolution.

Background: Aberrant activation of the canonical WNT signaling is a feature of colorectal cancer (CRC). Van-Gogh-like 2 (VANGL2) belongs to the non-canonical WNT pathway whose activation inhibits canonical WNT signaling. In this study, we investigated the role of VANGL2 and its epigenetic regulation in CRC. Methods: Van-Gogh-like 2 expression and promoter methylation after 5-aza-2′-deoxycytidine (5-aza) treatment were evaluated in CRC cells. DNA samples from 418 sporadic CRCs were tested for VANGL2 promoter methylation and microsatellite instability (MSI). Proliferation, colony formation and activation of the WNT pathway were tested in cells after VANGL2 overexpression. Results: Van-Gogh-like 2 mRNA was significantly higher in 5-aza-treated RKO, LOVO and SW48, whereas no differences were found in SW480. Van-Gogh-like 2 was fully methylated in RKO, SW48, HCT116, DLD1 and Caco2; partially methylated in LOVO, LS174T and SW837; and unmethylated in SW480, SW620 and HT29. Higher expression of VANGL2 mRNA was found in the unmethylated cell lines. In CRC specimens (8.93% MSI), methylated VANGL2 was associated with MSI, higher grade, proximal colon location and BRAF mutation. Van-Gogh-like 2 overexpression in SW480 significantly decreased proliferation, colony formation and β-catenin levels. Conclusion: Van-Gogh-like 2 is frequently methylated in MSI-CRCs with BRAF mutation and may act as a tumour suppressor gene, counteracting WNT/β-catenin signaling.

Abstract
BACKGROUND The most important side effect of radioiodine ((131)I) therapy is sialoadenitis and xerostomy. AIM To evaluate by ultrasound (US) parotid and submandibular glands after (131)I therapy for differentiated thyroid cancer (DTC). PATIENTS Seventy-six subjects thyroidectomized for DTC submitted to salivary glands US examination. Forty-three of them had been previously treated with (131)I: 22 with 1.11 GBq (30 mCi) for remnant ablation, and 21 with higher doses [up to 44.4 GBq (1200 mCi)] for metastases. Thirty-three subjects studied before (131)I therapy served as controls. Parotid and submandibular volume, homogeneity, and echogenicity were determined. (131)I-treated patients filled a questionnaire about sialoadenitis symptoms. RESULTS Parotid gland volume was significantly higher in treated patients (28.3±16.2 ml) than in untreated patients (20.7±10.4 ml, p=0.0154) and related to the time from last (131)I therapy. Three had parotid volume <1.5 ml and complained severe xerostomy. Submandibular gland volume was similar in treated (11.2±7.6 ml) and untreated patients (8.6±4.2 ml, p=0.0602). Homogeneity and echogenicity were similar in treated and untreated patients. Sialoadenitis symptoms were reported in 26% and were related to the (131)I cumulative dose. Symptoms were not related to gland volume. Hypoechogenicity and inhomogeneity of the parotids were more frequent in patients with salivary stickiness. CONCLUSION Parotid, but not submandibular, volume is increased after (131)I treatment depending on the received activity and the time from irradiation but not on sialoadenitis symptoms. Xerostomy is associated to gland atrophy at US.

Abstract
Recent literature highlights the importance of pro-inflammatory cytokines in the biology of breast cancer stem cells (CSCs), unraveling differences with respect to their normal counterparts. Expansion of mammospheres (MS) is a valuable tool for the in vitro study of normal and cancer mammary gland stem cells. Here, we expanded MSs from human breast cancer and normal mammary gland tissues, as well from tumorigenic (MCF7) and non-tumorigenic (MCF10) breast cell lines. We observed that agonists for the retinoid X receptor (6-OH-11-O-hydroxyphenanthrene), retinoic acid receptor (all-trans retinoic acid (RA)) and peroxisome proliferator-activated receptor (PPAR)-γ (pioglitazone (PGZ)), reduce the survival of MS generated from breast cancer tissues and MCF7 cells, but not from normal mammary gland or MCF10 cells. This phenomenon is paralleled by the hampering of pro-inflammatory Nuclear Factor-κB (NF-κB)/Interleukin-6 (IL6) axis that is hyperactive in breast cancer-derived MS. The hindrance of such pathway associates with the downregulation of MS regulatory genes (SLUG, Notch3, Jagged1) and with the upregulation of the differentiation markers estrogen receptor-α and keratin18. At variance, the PPARα agonist Wy14643 promotes MS formation, upregulating NF-κB/IL6 axis and MS regulatory genes. These data reveal that nuclear receptors agonists (6-OH-11-O-hydroxyphenanthrene, RA, PGZ) reduce the inflammation dependent survival of breast CSCs and that PPARα agonist Wy14643 exerts opposite effects on this phenotype.

Abstract
Cross-Reacting Material 197 (CRM197) is a diphtheria toxin non-toxic mutant that has shown antitumor activity in mice and humans. It is still unclear whether this anti-tumorigenic effect depends on its strong inflammatory-immunological property, its ability to inhibit heparin-binding epidermal growth factor (HB-EGF), or even its possible weak toxicity. CRM197 is utilized as a specific inhibitor of HB-EGF that competes for the epidermal growth factor receptor (EGFR), overexpressed in colorectal cancer and implicated in its progression. In this study we evaluate the effects of CRM197 on HT-29 human colon cancer cell line behaviour and, for CRM197 recognized ability to inhibit HB-EGF, its possible influence on EGFR activation. In particular, while HT-29 does not show any reduction of viability after CRM197 treatment (MTT modified assay), or changes in cell cycle distribution (flow cytometry), in EGFR localization, phospho-EGFR detected signals (immunohistochemistry) or in morphology (scanning electron microscopy, SEM) they show a change in the gene expression profile by microarray analysis (cDNA microarray SS-H19k8). The overexpression of genes like protein phosphatase 2, catalytic subunit, alpha isozyme (PPP2CA), guanine nucleotide-binding protein G subunit alpha-1(GNAI1) and butyrophilin, subfamily 2, member A1 (BTN2A1) has been confirmed with real-time-qPCR. This is the first study where the CRM197 treatment on HT-29 shows a possible scarce implication of endogenous HB-EGF on EGFR expression and cancer cell development. At the same time, our results show the alteration of a specific and selected number of genes.

Abstract
AIM The aim of the study was to detect and compare the epidermal growth factor receptor (EGFr) content using different methods, to establish whether the quantitative detection and functional study of EGFr in colorectal cancer, using methods other than immunohistochemistry (IHC), are appropriate. METHOD Analysis of EGFr by IHC was performed in 230 colorectal cancer patients using monoclonal anti-EGFr. Total and activated EGFr (pY1068) contents were determined in 92 patients and real-time PCR, to determine the level of EGFr messenger RNA, was carried out in 60 patients. RESULTS There was no association between EGFr IHC groups and the mean total EGFr levels measured using ELISA. CONCLUSION The study shows that the results of different EGFr detection methods do not correlate with each other. Hence, the real role of EGFr in colorectal cancer remains unsettled. Clinically, the receptor itself does not seem to be important and it would be better to focus on EGFr signalling in downstream pathways.

Abstract
Patients with clinical features of MEN 1 without mutations in the menin gene fulfill the criteria of MEN1-like syndrome. Primary hyperparathyroidism (PHP) is the most frequent clinical finding in both syndromes and is usually treated by surgery. However, PHP has been reported to respond to somatostatin analogues (SSA) in MEN 1 patients. 7 patients with PHP in the context of MEN 1-like syndrome (and absence of mutations in the menin gene) were enrolled in the study and treated with SSA for 6 months for the non-PHP disease before parathyroidectomy. Serum ionized calcium, phosphorus, and PTH concentrations, and 24-h urinary calcium and phosphorus excretion were measured before and after SSA therapy. Mean serum ionized calcium, phosphorus, and PTH concentrations did not significantly change after a 6-month course with SSA. SSA scintigraphy did not reveal uptake in the neck region corresponding to the parathyroid adenoma identified at surgery and confirmed at histology. However, immunohistochemistry revealed SS-type 2A receptor in parathyroid tissue samples of 6 out of 7 patients. SSA therapy does not affect calcium-phosphorus metabolism in patients with MEN 1-like syndrome, suggesting that the drug has no role in controlling PHP in these subset of patients.

Abstract
BACKGROUND 2-[fluorine-18]fluoro-2-deoxy-D-glucose-positron emission tomography/computed tomography (FDG-PET/CT) was carried out before and after neoadjuvant chemoradiotherapy (NCRT) followed by radical surgery for locally advanced rectal cancer (LARC). The aim of this study was to define its predictive and prognostic values. PATIENTS AND METHODS Patients with cT3-T4 N-/+ carcinoma of medium/low rectum received daily 5-fluorouracil-based chemotherapy infusion and radiation therapy on 6-week period followed by surgery 7-8 weeks later. Tumour metabolic activity, expressed as maximum standardised uptake value (SUV-1 = at baseline and SUV-2 = pre-surgery), was calculated in the most active tumour site. Predictive and prognostic values of SUV-1, SUV-2 and Δ-SUV (percentage change of SUV-1 - SUV-2) were analysed towards pathological response (pR) in the surgical specimen and disease recurrence, respectively. RESULTS Eighty consecutive patients entered the study. SUV-1, SUV-2 and Δ-SUV appeared singly correlated with pR, but not one of them resulted an independent predictive factor at multivariate analysis. After a median follow-up of 44 months, 13 patients (16.2%) presented local and/or distant recurrence. SUV-2 ≤5 was associated with lower incidence of disease recurrence and resulted prognostic factor at multivariate analysis. CONCLUSIONS Dual-time FDG-PET/CT in patients with LARC treated with NCRT and radical surgery supplies limited predictive information. However, an optimal metabolic response appears associated with a favourable patient outcome.

Abstract
Conventional 131I treatment has been used in the last 20 years for large nodular goitres when patients present high surgical risk or simply refuse surgery. 131I therapy causes a mean goitre volume reduction of about 40% after one year. However, the individual response is variable and for low radioiodine uptake and very large goitres, high 131I activities are needed in order to have a adequate 131I accumulation in the thyroid. rhTSH is approved for thyroid cancer management and has been tested off label in large goitres, in whom increases 131I uptake, thus reducing the 131I amount to be administered. The use of lower 131I activities allows to reduce the radiation burden to body and the time of social life restriction. Moreover, depending on the radiation regulations of the different countries, the 131I therapy could be carried out either as outpatients or in a shorter hospitalization period, implying a decrease of costs. The effects of rhTSH on goitre may be due not only to the 131I uptake increase, but also to a more homogeneous distribution of 131I in the gland, and to the thyroid cell activation that makes them more radiosensitive. Acute adverse effects are due to the surge of thyroid hormone in blood and to the goitre volume increase, that cause cardiac symptoms and tracheal compression, respectively. These effects are probably dose dependent and are negligible for rhTSH lower doses.

Abstract
Aims-To investigate whether deletion of the 1p36 region of chromosome 1 is independent of DNA ploidy in breast cancer cells.Methods-Preparations of nuclei from 64 fresh primary breast tumours were studied using dual target fluorescence in situ hybridisation (FISH) combining probes specific for the 1q12 (pUC 1.77) and 1p36 (1p-79) regions of chromosome 1. Signals were counted in 100-300 nuclei and the percentage of cells showing fewer p1-79 than pUC 1.77 signals was measured in each sample. DNA ploidy was investigated by cytofluorimetry in 55 tumour samples.Results-Chromosome 1 aberrations were detected in 56 samples. There were fewer p1-79 than pUC 1.77 signals in 53 samples. The 1p36 region was deleted in 11 samples in which a single p1-79 signal was detected; seven of these samples were diploid. Abnormalities were found in 17/24 diploid and 30/31 aneuploid tumours.Conclusions-Chromosome 1 aberrations, including deletion of the 1p36 region, were observed in diploid breast tumours. Deletion of the 1p36 region may be an early event in tumorigenesis. Given the frequency and importance of chromosome 1 aberrations in the biological behaviour of breast tumours, FISH, used in conjunction with cytofluorimetry, may be helpful for determining prognosis in patients with diploid tumours.

Abstract
Thyrotropin stimulating hormone (TSH) exerts a physiological stimulus to growth, function and ability to take up iodine of both normal and malignant follicular cells. For this reason, the metastases deriving from well differentiated thyroid cancer (DTC) can be effectively treated with radioiodine but this procedure requires a strong TSH stimulus that can be obtained by withdrawing the L-thyroxine (LT4) therapy. However, both the social and personal life of patients while they are withdrawing the LT4 therapy are heavily affected by hypothyroidism. After more than a decade since the development of recombinant human TSH (rhTSH), this molecule has been introduced in the clinical practice (1998 in USA and 2001 in Europe) as a safe and reliable alternative to LT4 withdrawal. For several years the main clinical application of rhTSH was for diagnostic purposes (i.e. thyroglobulin stimulation) but, after the more recent demonstration of its efficacy in preparing DTC patients for radioiodine post surgical thyroid remnant ablation, also this application has been officially recognized worldwide. The validity of rhTSH has been also demonstrated in stimulating metastatic thyroid cancer cells but this employment is not yet officially approved and it can be used only in patients with contraindication to hypothyroidism (i.e. "compassionate use"). Other possible uses of rhTSH stimulation are related to its ability to enhance both 18FDG uptake during PET scan of metastatic DTC patients and the effectiveness of conventional chemotherapy. The aim of this review was to recall how the rhTSH has been developed and progressively introduced in the clinical management of DTC patients.

Abstract
BACKGROUND Triple-negative breast cancer (TNBC) is an aggressive disease, nevertheless exhibiting a high response rate to chemotherapy. Since the retinoblastoma protein (pRb) loss confers a high sensitivity to chemotherapy regimens, we evaluated the prevalence of pRb loss in TNBCs and its relevance on the clinical outcome of patients treated with adjuvant chemotherapy. PATIENTS AND METHODS pRb status was prospectively evaluated by immunocytochemistry in 518 consecutive patients with complete receptor information. The predictive value of pRb status in TNBCs was determined according to the adjuvant therapeutic treatments. RESULTS Fifty-three tumors were identified as TNBCs. The prevalence of pRb loss was significantly higher in TNBCs than in the other cancer subtypes. All patients with TNBCs lacking pRb and treated with systemic chemotherapy (cyclophosphamide, methotrexate and 5-fluorouracil) were disease free at a medium follow-up time of 109 months, whereas the clinical outcome of those expressing pRb was significantly poorer (P = 0.008). Analysis of disease-free survival including the established anatomo-clinical prognostic parameters indicated pRb loss as the only significant predictive factor. CONCLUSIONS pRb loss is much more frequent in TNBCs than in the other breast cancer subtypes. Patients with TNBCs lacking pRb had a very favorable clinical outcome if treated with conventional adjuvant chemotherapy.

Abstract
e15503 Background: The prognosis of advanced gastric cancer (GC) patients (pt) is still poor despite the introduction of new chemotherapy regimens. In colorectal cancer (CRC) it has been demonstrated that KRAS or BRAF mutations are associated with resistance to treatment with the anti-EGFR mAbs. We have assessed whether, and to what extent, the mutational profile of KRAS and BRAF genes affects the response to cetuximab combination therapy in GC. Methods: We have collected 44 tumor samples from pts affected by locally advanced or metastatic GC undergoing cetuximab combination therapy as first-line treatment in two consecutive phase II studies. Thirteen pts received cetuximab plus FOLFIRI (FOLCETUX Study) and 31 pts cetuximab plus cisplatin and docetaxel (DOCETUX Study). Genomic DNA was extracted from paraffin-embedded tumor specimens from all cases. The mutational status of KRAS (exon 2) and BRAF (exon 15) was ascertained by PCR amplification followed by direct sequencing. The objective response was evaluated every 6 weeks by CT according to RECIST criteria. Results: KRAS and BRAF mutations were detected in 5 (11.4%) and 1 (2.3%), respectively, of the 44 tumors analyzed. These frequencies are consistent with those previously reported in GC. In the case of KRAS, 3 cases displayed amino acid substitutions of codon 12 and 1 of codon 13. One case had the A11V variant that had been reported in hematopoietic and lymphoid tissue of the stomach. The only BRAF mutation found in 1 sample was the classic V600E substitution. As a whole, 13.6 % of the analyzed tumors carried a mutation in either KRAS or BRAF genes. K-RAS and BRAF mutations were, as expected, mutually exclusive. In this pt cohort oncogenic activation of KRAS/BRAF-signaling pathways was not significantly associated to objective response (p= 0.757). Also, we found no correlation between KRAS/BRAF mutations and clinical outcome measured as overall survival. Conclusions: In advanced GC the frequency of mutations in KRAS and BRAF is lower as compared with CRC cancer. In our cases, the mutational status of KRAS and BRAF genes does not correlate with the response to cetuximab-based therapy in advanced gastric cancer patients.

Abstract
e21510 Background: GISTs show a wide spectrum of biological behaviors which translates in an even wider spectrum of possible clinical courses. The two canonical parameters used for the prediction of GISTs’ prognosis are tumor size and mitotic index. However, few but controversial data on Ki-67 are also available. The aim of our study was to clarify the role of Ki-67 expression as a new biological marker in GISTs. Methods: Forty-one cases of GIST were examined. Twenty-six cases arose from stomach and 15 from small bowel. Immunohistochemical analysis for Ki-67 was stained on tissue samples and a cut-off value of >10% immunoreactive cells was used to distinguish between low (<= 10%) and high (>10%) Ki-67 nuclear expression. The expression of this cell-cycle related protein was correlated with tumor site (stomach; any other site), dimensions (<5 cm; >=5cm), mitotic index (<=5/50 HPFs; >5/50 HPFs), standard risk groups (low; intermediate-high) and disease free survival (DFS). Results: Ki-67 over-expression was positively correlated with tumor size >=5cm (p= 0.035). Not significant but a positive trend was seen with intermediate and high risk groups (p = 0.114), mitotic index >5/50 HPFs (p = 0.615). Lower levels of Ki-67 expression have been observed in gastric GISTs compared to any other site (29 cases with Ki-67 <=10% of which 21 gastric and 8 in other sites), even if these values were not statistically significant (p = 0.527). Moreover, Ki-67 over-expression was found to be significantly associated with a shorter DFS interval (p = 0.0196, analysis performed on 32 cases). Conclusions: Our data demonstrate that Ki-67 over-expression is significantly correlated with larger GIST and with a shorter DFS, suggesting that Ki-67 evaluation can be a useful tool to predict biological behavior of GIST, even if further studies are needed. In a clinical perspective, such information could be used in association with standard risk factors to select patients who could benefit from adjuvant therapy.

Abstract
BACKGROUND Many reports were produced on single epidermal growth factor receptor (EGFr) and cyclo-oxygenase-2 (Cox-2) evaluation using immunohistochemical techniques (IHC), but very few works considered concurrent expression of these two proteins in the light of their impact on proliferation and tumour spreading. At least three molecular pathways (EGFr, Cox-2, and APC/beta-catenin molecular cascade) may interact in this malignancy giving rise to cross talking effects on proliferation and cancer spreading. PATIENTS AND METHODS To better detail these two latter aggressive features, we studied 205 sporadic colorectal cancer patients, comparing concurrent expression of EGFr, Cox-2, Ki-67, Cyclins D1-A, and E, with tumour spreading (budding) (BUD) and pN status. RESULTS Our results point to a different aggressive molecular profile due to Cox-2 expression. Cox-2 High expressing cases showed a clear EGFr proliferation-promoting role. On the contrary, EGFr seems directly involved in cancer cells spreading rather than in promoting cancer proliferation in Cox-2 Low/Negative cases. CONCLUSIONS Immunohistochemical profiling of colorectal cancer seems to be a promising approach, not only to define prognostic impact, but also to detail proliferation-related molecular interplays between EGFr and Cox-2 pathways, with these two latter proteins, at present, being the hottest pharmacological targets for colorectal cancer (CRC) chemoprevention and therapy.

Abstract
14518 Background: Biopathological colorectal cancer (CRC) studies have provided information on pathogenesis, but it is unclear how important biomarkers actually are in predicting prognosis. The aim of our study was to define the prognostic significance of biomarkers and a biopathological profile that could predict an increase in the disease relapse risk in stage II-III CRC patients (pts). Methods: The primary tumor of the CRC pts treated with surgery was immunohistochemically evaluated on the Ki67, p53, bcl-2, TS, EGFR, MLH1 and MSH2 expressions. All 7 markers were measured using standard immunohistochemical techniques. The biomarker evaluations were scored by just one pathologist. Results: Between March 2001 and October 2006 the primary tumor of 242 consecutive pts was investigated. Pt characteristics were: males 141(58.3%), females 101(41.7%); median age 68.5 (24–88); primary tumor site: right colon 94(38.8%), left colon 148(61.2%); stage II 102(42.1%), stage III 81(33.5%), stage IV 59(24.4%). 5-fluorouracil based adjuvant chemotherapy was performed in 121 (66.1%) pts. After a median follow up of 30 months (1–80), 34 pts (10 pts stage II, 24 pts stage III) of 183 stage II-III pts (18.6%) had a disease recurrence. In a univariate analysis of stage II-III pts, a higher expression of Ki67 (= 50% positive cells) was significantly associated with an improved DFS (p= 0.014) and overall survival (OS) (p=0.010). Expression of p53, bcl-2, TS, EGFR, MLH1 and MSH2 were not significantly associated with DFS and OS. In a multivariate analysis adjusted for the impact of the disease stage and adjuvant chemotherapy, a higher expression of Ki67 was significantly associated with diminished risk of recurrence (HR: 0.395; 95% CI: 0.183–0.855, p=0.018) and death (HR: 0.179; 95% CI: 0.046–0.696, p=0.013). The evaluation of DNA mismatch repair status (MLH1, MSH2) demonstrated that the lack of MLH1 is more frequent in non-relapsed II-III stage pts than in IV stage pts (p= 0.024). Conclusions: This analysis showed a significant correlation between higher Ki67 expression and better DFS and OS in pts with stage II-III CRC. An higher frequency of MLH1 deficiency was observed in non-relapsed pts with stage II-III than in advanced disease. No significant financial relationships to disclose.

Abstract
4604 Background: The aim of this study was to evaluate the correlation between pathologic biomarkers and objective response (OR), time to progression (TTP) and overall survival (OS) in advanced gastric or gastroesophageal junction (GEJ) cancer patients (pts) treated with cetuximab plus FOLFIRI. Methods: We analysed 32/38 pts with stomach or GEJ locally advanced/metastatic adenocarcinoma, EGFR+, enrolled in the Italian FOLCETUX study. The pts were treated as first line with cetuximab weekly at 400 mg/m2 iv loading dose, and then at 250 mg/m2 iv maintenance dose, plus FOLFIRI every 2 weeks, for a maximum of 24 weeks, then cetuximab alone was allowed in pts with CR/PR/SD. Expression of Ki67, p53, TS and EGFR was examined immunohistochemically in primary tumor and/or metastasis samples. Ki67, p53 and TS were categorized into a low and high value; EGFR was categorized into low, intermediate and high values. High cut-off was defined as: >50% Ki67; >20% p53; =9% cytoplasmatic and >30% nuclear TS; EGFR score (combining % neoplastic cell positive and intensity) was: low=0–2, intermediate=3–5, high=6–7. To avoid any discrepant evaluation the assessment was carried out centrally by just one pathologist. Results: The pt characteristics were: 22M/10F; median age 64.5 years (39–83); stomach 29(90.6%), GEJ 3(9.4%); intestinal histotype 21(65.6%), non-intestinal 11(34.4%); locally advanced disease 4(12.5%), metastatic disease 28(87.5%). The OR were: 15 CR+PR, 15 SD, 2 PD. No relationship was observed between Ki67, p53, TS and EGFR expression and OR (Chi-squared test/Fisher’s Exact Test). In the multivariate analysis adjusted for the impact of intestinal/non-intestinal histotype and locally advanced/metastatic disease, the low TS expression was associated with an improved TTP ( Table 1 ). Conclusions: This results suggest that TS, EGFR, p53 and Ki67 expressions are not significantly correlated with OR. Low TS expression is predictive of better TTP.

Abstract
14514 Background: The aim of this study was to evaluate the prognostic value of histologic tumor regression grade (TRG) and pathological biomarkers after neoadjuvant chemoradiotherapy (CT/RT) in rectal cancer pts. Methods: Pts entering the study had rectal adenocarcinoma and stage uT3-T4 N-/+ with location <12 cm from the anal margin. CT consisted of 5-fluorouracil (5FU) 225 mg/m2/die continuous infusion IV d1–38 with/without oxaliplatin (OXA) 60 mg/m2 weekly infusion IV for 6 times. RT was delivered up to a dose of 50.4 Gy in daily fractions of 1.8 Gy. Rectal surgery with TME was performed 6–8 weeks after neoadjuvant therapy. Eight courses of adjuvant CT (LV5FU2) were given after surgery. Immunohistochemical determination of Ki67, p53, bcl2, TS, EGFR, MLH1, MSH2 was performed in pre-treatment biopsy and operative specimen; TRG (Dworak) response (0=none, 1=low, 2–3= intermediate, 4=complete) and circumferential resection margin (CRM) were evaluated on surgical specimens. Results: Between March 2002 and December 2006, 56 pts had completed the integrated treatment. Pt characteristics were: 39M/17F; stage uT3N- 32(57.1%), uT3N+ 15(26.8%), uT3Nx 4(7.1%), uT4N+ 4(7.1%), uT4Nx 1(1.8%). CT was 5FU in 15(26.8%) pts, 5FU/OXA in 41(73.2%) pts. Pathological downstaging was achieved in 31(55.4%) pts, including 9(16.1%) pCR. After a median follow-up of 28.5(6–58) months, 7(12.5%) pts had disease recurrence. TRG evaluation was: no TRG0, 9(16.1%) TRG1, 21(37.5%) TRG2, 17(30.4%) TRG3, 9(16.1%) TRG4. CRM was negative in 91% of pts. By means of univariate analysis, TRG was found to be significantly correlated with DFS (estimated median DFS was 23 months in TRG1 pts, not achieved in TRG2–4 pts; p<0.0001). Other factors correlating significantly with a better DFS by univariate analysis included ypT0–2 (p=0.013) and pN- (p=0.002) categories, CRM- (p=0.024) and lower Ki67 expression post-CT/RT (p=0.012). Using multivariate analysis, we found that TRG2–4 was the strongest DFS prognostic factor (HR=0.0312; 95% CI: 0.003–0.40, p=0.008). Conclusions: In this analysis complete (TRG4) and intermediate (TRG2+3) pathological response produced improved DFS. Significant favorable prognostic factors were the ypT0–2/pN- categories, CRM- status and lower Ki67 expression after CT/RT. No significant financial relationships to disclose.

Abstract
Recent data challenge the relevance of the RB pathway to cancer based on RB inactivation, at least in breast tumors. To obtain information on the actual role of the components of the RB pathway in tumor progression we decided to investigate whether their quantitative changes were associated with variations in the level of RB phosphorylation in human breast cancer. A series of 68 human primary breast carcinomas was studied. Five cases were excluded from the study due to their lack of RB expression. In the remaining 63 cases the expression of cyclin D1, cdk4, cyclin E, and INK4a mRNA was assessed by real-time RT-PCR. The level of RB phosphorylated protein (ppRB) and p27 expression was immunohistochemically analyzed by measuring the percentage of stained cells (labeling index, LI). Cell proliferation rate was measured by Ki67 LI evaluation. The ppRB LI ranged from 5.2 to 73.8 and, as expected, was strongly related to the Ki67 LI (r=0.80; p<0.001). The expression of cyclin D1 mRNA, expressed in arbitrary units (a. u.), ranged from 1.15 to 123.0 and was inversely related to the ppRB LI (p=0.021) and Ki67 LI (p<0.001). Neither the cdk4 (range from 0.07 to 1.13 a. u.) nor the cyclin E (range from 0.13 to 9.27 a. u.) mRNA expression was significantly associated with the ppRB LI (p=0.962 and p=0.103, respectively). Cyclin E was related to Ki67 LI (p=0.022). Both INK4a mRNA (range from 0.01 to 0.60 a. u.) and p27 (LI from 0.0 to 73.1) values were inversely related to the ppRB LI (p=0.022 and p=0.014, respectively). Cyclin D1, cdk4, and cyclin E mRNA expressions were not significantly related to one another. In human primary breast cancers, the expression levels of the factors known to facilitate the cell cycle progression by RB protein phosphorylation were not positively related to ppRB-LI. Pathological increases of cyclin D, cdk4, and cyclin E are very likely associated with other biological functions other than their well-established action on cell cycle progression.

Abstract
The aim of the present study was to ascertain the relationship between the level of RB1 mRNA and the expression of phosphorylated RB protein and the relevance of these two parameters in cancer cell proliferation and clinical outcome in human breast cancer. Sixty-eight primary human breast cancers were considered. The amount of RB1 mRNA was evaluated by quantitative RT-PCR analysis. The level of RB phosphorylation was immunohistochemical defined by measuring the phosphorylated (pp) RB labelling index (LI). Cell proliferation rate was measured by calculating the Ki67 LI. No relation was found between the RB1 mRNA level and the ppRB LI (p=0.565). Both RB1 mRNA value and ppRB LI were related (in an inverse and direct manner, respectively) to Ki67 LI. RB1 mRNA expression was more strictly associated with KI67 LI (p=0.001) than the ppRB LI (p=0.013). Regarding the patient clinical outcome, the separately considered RB parameters did not reach the prognostic significance. However, patients with low RB1 mRNA quantity and patients with high ppRB LI, taken together, had a significantly shorter disease free and overall survival than the group comprehending patients with high RB1 mRNA value and low ppRB LI, and this despite the low number of patients considered. Our results demonstrated that the ppRB LI was independent of the RB1 mRNA level; that both RB parameters are related to the cell proliferation rate and, if collectively considered, have a high informative value on breast tumour prognosis.
