Abstract
First-line immunotherapy in non-small-cell lung cancer largely improved patients' survival. PD-L1 testing is required before immune checkpoint inhibitor initiation. However, this biomarker fails to accurately predict patients' response. On the other hand, immunotherapy exposes patients to immune-related toxicity, the mechanisms of which are still unclear. Hence, there is an unmet need to develop clinically approved predictive biomarkers to better select patients who will benefit the most from immune checkpoint inhibitors and improve risk management. Single-cell technologies provide unprecedented insight into the tumor and its microenvironment, leading to the discovery of immune cells involved in immune checkpoint inhibitor response or toxicity. In this review, we will underscore the potential of the single-cell approach to identify candidate biomarkers improving non-small-cell lung cancer patients' care.

Abstract
Abstract
Objective. In the present hadrontherapy scenario, there is a growing interest in exploring the capabilities of different ion species other than protons and carbons. The possibility of using different ions paves the way for new radiotherapy approaches, such as the multi-ions treatment, where radiation could vary according to target volume, shape, depth and histologic characteristics of the tumor. For these reasons, in this paper, the study and understanding of biological-relevant quantities was extended for the case of 4He ion. Approach. Geant4 Monte Carlo based algorithms for dose- and track-averaged LET (Linear Energy Transfer) calculations, were validated for 4He ions and for the case of a mixed field characterised by the presence of secondary ions from both target and projectile fragmentation. The simulated dose and track averaged LETs were compared with the corresponding dose and frequency mean values of the lineal energy,

Abstract
RATIONALE Limbic encephalitis is one of the most common paraneoplastic neurological disorders (PND). The role of brain Fluorine-18-fluorodeoxyglucose position emission tomography/computed tomography (CT) in paraneoplastic limbic encephalitis (PLE) and of the whole body 18F-FDG PET/CT in this setting, remains still not well defined. PATIENT CONCERNS We report a case of a patient with chronic inflammatory rheumatism, psoriasis and Hashimoto thyroiditis and subsequent appearance of static and dynamic ataxia and episodic memory deficit who was diagnosed as PLE combined with small cell lung cancer (SCLC). DIAGNOSES The diagnosis of SCLC was made with EBUS-TBNA of a mediastinal lymph node. INTERVENTIONS Whole-body 18F-FDG PET/CT was performed for the initial staging of SCLC, in the planning of radiotherapy treatment, to evaluate therapeutic response and in the follow-up. A dedicated brain scan was included to the same PET session. Whole-body contrast enhanced computed tomography (CT) and contrast enhanced whole-brain MRI were also performed. OUTCOMES She was administered neoadjuvant chemioterapy with Cisplatin and Etoposide with concomitant radiotherapy treatment. Whole body 18F-FDG PET/CT showed a complete metabolic response already after 3 cycles of chemioterapy. Brain functional study showed a metabolic pattern characterized by the migration of hypermetabolism in the bilateral hippocampal areas during the therapeutic treatment, which correlated with the persistence of clinical symptoms. LESSONS In the era of personalized medicine and targeted therapy, this case highlights the importance of the 18F-FDG PET/CT study as an accurate tool to identify PLE and to guide the diagnostic work-up of the underlying tumor. Considering that most of these are 18F-FDG avid tumors and that the 18F-FDG PET/CT scan is often added to the diagnostic work-up when screening patients for malignancy, this functional imaging can play a decisive role.

Abstract
We have searched for periodic variations of the electronic recoil event rate in the (2-6) keV energy range recorded between February 2011 and March 2012 with the XENON100 detector, adding up to 224.6 live days in total. Following a detailed study to establish the stability of the detector and its background contributions during this run, we performed an unbinned profile likelihood analysis to identify any periodicity up to 500 days. We find a global significance of less than 1σ for all periods, suggesting no statistically significant modulation in the data. While the local significance for an annual modulation is 2.8σ, the analysis of a multiple-scatter control sample and the phase of the modulation disfavor a dark matter interpretation. The DAMA/LIBRA annual modulation interpreted as a dark matter signature with axial-vector coupling of weakly interacting massive particles to electrons is excluded at 4.8σ.

Abstract
Diabetic foot pathology represent the more disabling complication of diabetes. More the 1 million of diabetes patients undergo a lower limb amputation per year; 85% of these amputation are preceded by un ulcer that can be avoided by a prevention program. Critical limb ischemia (CLI), the only independent cause of major amputation in diabetic population, can be correctly treated when an early diagnosis is made. Both endoluminal and surgical revascularization procedures can be applied in diabetes with high rate of success when performed by skilled operator. Infection of diabetic foot, in particular in patients suffering from peripheral artery disease (PVD), may rapidly evolves in severe local or systemic infection putting the patient at high risk of major amputation or death. Together with an early diagnosis of infection and ischemia it is mandatory to apply a correct medical and surgical treatment protocol with the aim to control infection and to improve blood perfusion to the foot. In case of infection surgical procedure should be applied first while revascularization procedure will follow soonest. Antibiotic therapy should be chosen considering different local biological pattern and different type of infection. Reconstructive surgery, the last step in treatment of any diabetic foot lesion, must obtain a functional residual foot or a stump that will allow the patient to go back walking soonest with residual good walking capacity.

Abstract
We present new experimental constraints on the elastic, spin-dependent WIMP-nucleon cross section using recent data from the XENON100 experiment, operated in the Laboratori Nazionali del Gran Sasso in Italy. An analysis of 224.6 live days×34 kg of exposure acquired during 2011 and 2012 revealed no excess signal due to axial-vector WIMP interactions with 129Xe and 131Xe nuclei. This leads to the most stringent upper limits on WIMP-neutron cross sections for WIMP masses above 6 GeV/c², with a minimum cross section of 3.5×10(-40) cm² at a WIMP mass of 45 GeV/c², at 90% confidence level.

Abstract
We report on a search for particle dark matter with the XENON100 experiment, operated at the Laboratori Nazionali del Gran Sasso for 13 months during 2011 and 2012. XENON100 features an ultralow electromagnetic background of (5.3 ± 0.6) × 10(-3) events/(keV(ee) × kg × day) in the energy region of interest. A blind analysis of 224.6 live days × 34 kg exposure has yielded no evidence for dark matter interactions. The two candidate events observed in the predefined nuclear recoil energy range of 6.6-30.5 keV(nr) are consistent with the background expectation of (1.0 ± 0.2) events. A profile likelihood analysis using a 6.6-43.3 keV(nr) energy range sets the most stringent limit on the spin-independent elastic weakly interacting massive particle-nucleon scattering cross section for weakly interacting massive particle masses above 8 GeV/c(2), with a minimum of 2 × 10(-45) cm(2) at 55 GeV/c(2) and 90% confidence level.

Abstract
We present results from the direct search for dark matter with the XENON100 detector, installed underground at the Laboratori Nazionali del Gran Sasso of INFN, Italy. XENON100 is a two-phase time-projection chamber with a 62 kg liquid xenon target. Interaction vertex reconstruction in three dimensions with millimeter precision allows the selection of only the innermost 48 kg as the ultralow background fiducial target. In 100.9 live days of data, acquired between January and June 2010, no evidence for dark matter is found. Three candidate events were observed in the signal region with an expected background of (1.8 ± 0.6) events. This leads to the most stringent limit on dark matter interactions today, excluding spin-independent elastic weakly interacting massive particle (WIMP) nucleon scattering cross sections above 7.0 × 10(-45) cm(2) for a WIMP mass of 50 GeV/c(2) at 90% confidence level.

Abstract
The XENON100 experiment, in operation at the Laboratori Nazionali del Gran Sasso in Italy, is designed to search for dark matter weakly interacting massive particles (WIMPs) scattering off 62 kg of liquid xenon in an ultralow background dual-phase time projection chamber. In this Letter, we present first dark matter results from the analysis of 11.17 live days of nonblind data, acquired in October and November 2009. In the selected fiducial target of 40 kg, and within the predefined signal region, we observe no events and hence exclude spin-independent WIMP-nucleon elastic scattering cross sections above 3.4 × 10⁻⁴⁴ cm² for 55 GeV/c² WIMPs at 90% confidence level. Below 20 GeV/c², this result constrains the interpretation of the CoGeNT and DAMA signals as being due to spin-independent, elastic, light mass WIMP interactions.

Abstract
INTRODUCTION Nodular lesions within the neck may origin from several structures. A misdiagnosed origin may expose the surgeon to inappropriate procedures. These lesions are paradoxically frequent in high specialised centre for endocrine surgery. PATIENTS AND METHODS In the year 2006, three patients were first admitted to our department with a diagnosis of thyroid nodule (1) or lymphatic metastases of thyroid carcinoma (2). The first patient had ultrasound (US) and Tc-99-m scan orienting for thyroid nodule. The two other patients, presented with lateral neck lesion in ipsilateral sincronous and previous diagnosis of papillary thyroid carcinoma, respectively, with US and computed tomography scan confirmed lesion but with a FNA cytology negative for tumoural cells. RESULTS All three patients underwent surgical exploration. In the first two cases, a whitish tender nodule (4 and 4.5cm), cleavable from surrounding structures, was removed with final histology of Schwannoma and Paraganglioma, respectively. Both patients experienced Bernard Horner Syndrome. In the last patients, a firm grey nodule of 5cm strictly adherent to muscular planes was removed with diagnosis of Castleman's Disease. CONCLUSIONS Nodular neck lesions mimicking a thyroid pathology (thyroid nodules or metastatic lymph nodes) are rare but can represent a tough challenge for surgeons who might fall into incorrect surgical approaches, resulting in high morbidity. Pre-operative work-up would help the surgeon to obtain the correct diagnosis, thus, to follow the better surgical approach. Nevertheless, a careful approach would be used for that neurogenic tumour amenable of resection without jeopardising nervous structures.

Abstract
OBJECTIVE Recently, a multicenter study in differentiated thyroid cancer (DTC) patients showed that 3700 MBq 131-iodine ((131)I) after recombinant human TSH (rhTSH) had a successful thyroid ablation rate similar to that obtained after thyroid hormone withdrawal. We investigated whether 1850 MBq (131)I had a similar successful rate to 3700 MBq in patients prepared with rhTSH. DESIGN A total of 72 patients with DTC were randomly assigned to receive 1850 (group A, n = 36) or 3700 MBq (group B, n = 36) (131)I after rhTSH. One injection of 0.9 mg rhTSH was administered for 2 consecutive days; (131)I therapy was delivered 24 h after the last injection, followed by a posttherapy whole-body scan. Successful ablation was assessed 6-8 months later. RESULTS Successful ablation (no visible uptake in the diagnostic whole-body scan after rhTSH stimulation) was achieved in 88.9% of group A and B patients. Basal and rhTSH-stimulated serum thyroglobulin was undetectable (<1 ng/ml) in 78.9% of group A and 66.6% of group B patients (P = 0.46). Similar rates of ablation were obtained in both groups also in patients with node metastases. CONCLUSION Therapeutic (131)I activities of 1850 MBq are equally effective as 3700 MBq for thyroid ablation in DTC patients prepared with rhTSH, even in the presence of node metastases.

Abstract
PURPOSE Positron emission tomography is the most advanced scintigraphic imaging technology and can be employed in the planning of radiation therapy (RT). The aim of this study was to evaluate the possible role of fused images (anatomical CT and functional FDG-PET), acquired with a dedicated PET/CT scanner, in delineating gross tumour volume (GTV) and clinical target volume (CTV) in selected patients and thus in facilitating RT planning. METHODS Twenty-eight patients were examined, 24 with lung cancer (17 non-small cell and seven small cell) and four with non-Hodgkin's lymphoma in the head and neck region. All patients underwent a whole-body PET scan after a CT scan. The CT images provided morphological volumetric information, and in a second step, the corresponding PET images were overlaid to define the effective target volume. The images were exported off-line via an internal network to an RT simulator. RESULTS Three patient were excluded from the study owing to change in the disease stage subsequent to the PET/CT study. Among the remaining 25 patients, PET significantly altered the GTV or CTV in 11 (44%) . In five of these 11 cases there was a reduction in GTV or CTV, while in six there was an increase in GTV or CTV. CONCLUSION FDG-PET is a highly sensitive imaging modality that offers better visualisation of local and locoregional tumour extension. This study confirmed that co-registration of CT data and FDG-PET images may lead to significant modifications of RT planning and patient management.

Abstract
The urinary 6beta-OH-cortisol/cortisol ratio is a specific, non-invasive marker for evaluating inductive or inhibitory effects on cytochrome P450 3A activity. We propose a new quantitative gas chromatography-mass spectrometry with isotope dilution (GC-ID-MS) method for the simultaneous determination of urinary free cortisol (UFC) and 6beta-OH-cortisol (6beta-OHC). The method utilizes the following: (a) addition of internal standard (2H2 cortisol) to 1 ml of urine; (b) loading on to an Extrelut column and elution with dichloromethane; (c) derivatization to dimethoxime tri-(trimethyl-silyl)ether (MOX-TMS); (d) separation and identification by GC-ID-MS. The detection limit for cortisol was 22 pg injected (signal-to-noise ratio 10:1) and for 6beta-OH-cortisol 123 pg injected (signal-to-noise ratio 10:1). The intra-assay and the inter-assay imprecision were 4.69% and 7.4% for 6beta-OHC and 2.44% and 3.53% for cortisol, respectively. We used this method to analyze 57 morning urine samples of healthy volunteers and patients under different conditions. We found that chronic alcoholics had a significantly higher ratio of 6beta-OHC/UFC compared to controls (p<0.0001), whereas adults undergoing methadone therapy and patients with acute alcohol intoxication exhibited a significantly lower urinary 6beta-OHC/UFC ratio (p<0.05 and p<0.01, respectively). The proposed method allows a rapid and accurate assessment of the 6beta-OHC/UFC ratio.

Abstract
BACKGROUND Early node dissection offers increased survival in patients with node metastases only. The study of sentinel node (SN) using blue dye and radiolocalization permits to identify patients who could undergo lymphadenectomy. METHODS At Department of Surgery of Macerata General Hospital 22 patients with melanoma of trunk or limbs at I and II stage were submitted to SN biopsy. RESULTS SN was identified in all cases by combined approach. Dynamic lymphoscintigraphy permitted identification of SL when it was not the node nearest the tumor. Nodal metastases were found in 2 cases (9.1%) and the patients underwent regional lymphadenectomy. In 1 patient the SN was the only node with metastases. Both patients had high thickness melanomas. The measurement of radioactive exposition for operating room personnel and pathologist demonstrated that the technique is safe and without risks. CONCLUSIONS Biopsy of SN is effective for identification of occult nodal metastases from cutaneous melanoma. Combined technique allows to localize SN in 100% of cases. There is not radio-exposition for operators.

Abstract
127 fine-needle aspiration biopsies obtained under ultrasonographic control from circumscribed kidney lesions of 102 patients (with histologically examined lesions) were selected from a total of 867 fine-needle aspiration biopsies performed in the years between 1978 and 1986. The result of the cytological examination was compared with the histological diagnosis of the lesion. A correct diagnosis of the nature of the lesion (concerning dignity) was achieved in 90.2% of the cases under optimal circumstances. No mistakenly positive diagnosis was made. A total of 88% of the histologically malignant tumors or 80.2% of the kidney cancers were correctly diagnosed already on the basis of the cytological examination. The fine-needle aspiration can be repeated when the obtained material is insufficient: A kidney cancer was diagnosed in this way 13 times among 22 patients. The cytological examination permitted a more precise tumor-type differentiation in the large majority of cases. These results demonstrate the value of this diagnostic tool that carries only an irrelevant risk.
