Dataset related to article "CXCR4/CXCL12 Signaling and Protumor Macrophages in Primary Tumors and Sentinel Lymph Nodes Are Involved in Luminal B Breast Cancer Progression"
<p>This record contains raw data related to article "CXCR4/CXCL12 Signaling and Protumor Macrophages in Primary Tumors and Sentinel Lymph Nodes Are Involved in Luminal B Breast Cancer Progression"</p> <p>Luminal B breast cancers (BC) have a more aggressive behavior associated with a higher rate of tumor relapse and worse prognosis compared to luminal A tumors. In this study, we evaluated the involvement of specific epithelial-to-mesenchymal transition- (EMT-) and immune-related pathways in the dissemination of luminal B BC cells. The expression of 42 EMT- and immune-related genes was evaluated in matched sentinel lymph nodes (SLNs) analyzed by the one-step nucleic acid amplification assay (OSNA) and primary tumors of 40 luminal B BC patients by gene array and immunohistochemistry. The results were validated in an independent group of 150 luminal B tumors by immunohistochemistry and immunofluorescence and using gene expression data from 315 luminal B BC patients included in the Metabric dataset. We found that the expression of <em>CXCR4</em> (<em>p</em> = 3.28<em>E</em> - 02) and <em>CD163</em> (<em>p</em> = 6.92<em>E</em> - 03) was significantly upregulated in SLNs of recurrent luminal B BC patients. Luminal B primary tumors overexpressing CXCR4 were characterized by an increased expression of vimentin and a high content of CD163-positive macrophages. Bioinformatics analysis confirmed the correlation of <em>CXCR4</em> with <em>CXCL12</em>, <em>VIM</em>, and <em>CD163</em> expression and LN involvement. Our results suggest that the upregulation of the CXCR4/CXCL12 pathway and the presence of protumor macrophages in the primary tumor and SLNs sustain the aggressiveness of an important subgroup of luminal B BC.</p>

Dataset related to article "Critical Appraisal of the Risk of Secondary Cancer Induction From Breast Radiation Therapy With Volumetric Modulated Arc Therapy Relative to 3D Conformal Therapy"
<p>This record contains raw data related to article "Critical Appraisal of the Risk of Secondary Cancer Induction From Breast Radiation Therapy With Volumetric Modulated Arc Therapy Relative to 3D Conformal Therapy"</p> <p>PURPOSE:</p> <p>To evaluate the excess absolute risk (EAR) comparing volumetric modulated arc therapy (VMAT) and 3-dimensional (3D) conformal radiation therapy (CRT) in breast cancer radiation therapy treatment.</p> <p>METHODS AND MATERIALS:</p> <p>Two VMAT arrangements (VMAT_tang and VMAT_full, i.e. partial arcs with and without a sector of 0 Monitor Unit, respectively) and a 3D CRT (field-in-field [FinF]) plan were calculated with an accurate dose calculation algorithm, Acuros, in 20 patients presenting with early-stage breast cancer. The dose prescription was 40.05 Gy in 15 fractions. The planning aim was to maximize the dose reduction in the lungs, contralateral breast, heart, and coronary artery. EAR was estimated using different models: linear, linear-exponential, plateau, and full model, which better uses a carcinogenesis model and epidemiologic data for carcinoma induction and which accounts for cell repopulation or repair during the radiation therapy dose fractionation. EAR was computed for contralateral structures-breast and lung-as well as the ipsilateral lung. Normal tissue complication probability (NTCP) was computed to estimate the ipsilateral lung, heart, and skin toxicity, to balance with respect to second cancer induction.</p> <p>RESULTS:</p> <p>The planning objectives were fulfilled with all the planning techniques. EAR for contralateral breast carcinoma induction, estimated with the most accurate model, was 1.7, 2.4, and 8.5 (per 10,000 patients per year) with FinF, VMAT_tang, and VMAT_full, respectively. For the contralateral lung, these figures were 1.5, 1.6, and 7.3 (per 10,000 patients per year), respectively. NTCP for all the analyzed endpoints was significantly higher with FinF relative to both VMAT settings, with VMAT_full presenting the lowest toxicity risk.</p> <p>CONCLUSIONS:</p> <p>VMAT, in particular with the VMAT_tang setting, could have the same risk of second cancer induction as 3D CRT delivered with the FinF setting for the contralateral organs while reducing acute and late NTCP for the ipsilateral organs. VMAT might be considered a safe technique for breast cancer treatment for those aspects.</p>
Dataset related to article "Convolutional Neural Networks Promising in Lung Cancer T-Parameter Assessment on Baseline FDG-PET/CT"
<p>This record contains raw data related to article "Convolutional Neural Networks Promising in Lung Cancer T-Parameter Assessment on Baseline FDG-PET/CT"</p> <p>Aim:</p> <p>To develop an algorithm, based on convolutional neural network (CNN), for the classification of lung cancer lesions as T1-T2 or T3-T4 on staging fluorodeoxyglucose positron emission tomography (FDG-PET)/CT images.</p> <p>Methods:</p> <p>We retrospectively selected a cohort of 472 patients (divided in the training, validation, and test sets) submitted to staging FDG-PET/CT within 60 days before biopsy or surgery. TNM system seventh edition was used as reference. Postprocessing was performed to generate an adequate dataset. The input of CNNs was a bounding box on both PET and CT images, cropped around the lesion centre. The results were classified as Correct (concordance between reference and prediction) and Incorrect (discordance between reference and prediction). Accuracy (Correct/[Correct + Incorrect]), recall (Correctly predicted T3-T4/[all T3-T4]), and specificity (Correctly predicted T1-T2/[all T1-T2]), as commonly defined in deep learning models, were used to evaluate CNN performance. The area under the curve (AUC) was calculated for the final model.</p> <p>Results:</p> <p>The algorithm, composed of two networks (a "feature extractor" and a "classifier"), developed and tested achieved an accuracy, recall, specificity, and AUC of 87%, 69%, 69%, and 0.83; 86%, 77%, 70%, and 0.73; and 90%, 47%, 67%, and 0.68 in the training, validation, and test sets, respectively.</p> <p>Conclusion:</p> <p>We obtained proof of concept that CNNs can be used as a tool to assist in the staging of patients affected by lung cancer.</p>
Dataset related to article: "Full Interchangeability in Regard to Immunogenicity Between the Infliximab Reference Biologic and Biosimilars CT-P13 and SB2 in Inflammatory Bowel Disease"
<p>This record contains raw data related to article "Full Interchangeability in Regard to Immunogenicity Between the Infliximab Reference Biologic and Biosimilars CT-P13 and SB2 in Inflammatory Bowel Disease"</p> <p>Infliximab (IFX) biosimilars CT-P13 and SB2 have comparable efficacy, safety, and immunogenicity to the originator Remicade (RMC). However, concerns about cross-switching patients between the 3 brands were raised in the absence of cross reactivity data between them. We aimed to determine whether antibodies to infliximab (ATI) in inflammatory bowel disease (IBD) patients cross-react with RMC, CT-P13, and SB2.</p> <p>Methods:</p> <p>Based on previous ATI status, samples from 34 patients participating in the BIOSIM01 study (13 RMC, 9 CT-P13, and 12 switchers) were selected. Patients were treated with either RMC only, or CT-P13 only, or with RMC switched to CT-P13. Additionally, 28 IFX-naïve patients were assayed as controls. In total, 180 samples were analyzed. ATI trough levels were measured in parallel with 3 different bridging Enzyme Linked Immunosorbent Assays constructed using the 3 drugs. Spearman's coefficient and percentages of agreement were used to study the correlation between each assay.</p> <p>Results:</p> <p>In total, 76 samples out of 152 IFX-treated patient samples were ATI-positive (30 RMC, 14 CT-P13, and 32 switchers). All resulted ATI-positive when either CT-P13 or SB2 bridging assays were used. The overall percentage of agreement was 100% when compared either with CT-P13 or SB2 assays. No significant differences were found among ATI levels and coefficients (Spearman's 0.98 to 1.0, P < 0.0001).</p> <p>Conclusions:</p> <p>ATI of RMC-treated, CT-P13-treated or RMC to CT-P13 switched patients show full cross-reactivity with CT-P13 and SB2. Findings suggest that immunodominant epitopes in the reference and CT-P13 drugs are equally present in SB2. Data support full interchangeability between biosimilars in regard to immunogenicity.</p>
Dataset related to article "'Quality of Care' Standards in Inflammatory Bowel Disease: A Systematic Review."
<p>This record contains raw data related to article " 'Quality of Care' Standards in Inflammatory Bowel Disease: A Systematic Review."</p> <p>Background:</p> <p>Inflammatory bowel disease [IBD] includes chronic, disabling and progressive conditions that need a complex approach and management. Although several attempts have been made to standardize the care of IBD patients, no clear definitions of a global 'standard of care' are currently available.</p> <p>Methods:</p> <p>We performed a systematic review of the available literature, searching for all relevant data concerning three main domains of standards of quality of care in IBD patients: structure, process and outcomes. From the literature search, 2394 abstracts were retrieved, and 62 relevant papers were included in the final review.</p> <p>Results:</p> <p>Standards of quality of care in IBD include several aspects that can be summarized in three identified domains: structure, process and outcomes. The suggested structure of an IBD Unit includes a multi-disciplinary approach, effective referral processes, improved access using helplines, and departmental guidelines/pathways with identification of measurable quality indicators. Coordinated care models which incorporate a multi-disciplinary approach, structured clinical pathways or processes for the diagnosis, monitoring and treatment of IBD, fast-track recovery from IBD surgery, designated IBD clinics, virtual clinics and telemanagement are currently considered the main standards for process, although supporting data are limited. Several consensus statements on outcomes and quality indicators have been reported, focusing on outcomes in symptoms, function and quality of life restoration, survival and disease control, in addition to effective healthcare utilization.</p> <p>Conclusions:</p> <p>The results of this systematic review can provide the basis for general recommendations for standards of quality of care in IBD.</p>
Dataset related to article "Critical appraisal of the potential role of intensity modulated proton therapy in the hypofractionated treatment of advanced hepatocellular carcinoma"
<p>This record contains raw data related to article "Critical appraisal of the potential role of intensity modulated proton therapy in the hypofractionated treatment of advanced hepatocellular carcinoma"</p> <p>PURPOSE:</p> <p>To investigate the role of intensity modulated proton therapy (IMPT) for advanced hepatocellular carcinoma in comparison with volumetric modulated arc therapy (VMAT).</p> <p>METHODS:</p> <p>An in-silico planning study was performed on 20 patients. The prescription dose was 60Gy in 6 fractions. Patients were planned with abdominal compression. IMPT plans were optimized with or without the inclusion of CT calibration (3%) and isocenter positioning (2,4,6mm) uncertainties. Plan robustness was appraised comparing rubust optimized plans vs standard plans and also in terms of the worst-case scenario. VMAT plans were optimized for 10FFF photon beams using 2 partial arcs.</p> <p>RESULTS:</p> <p>Target coverage was fully achieved by both VMAT and IMPT plans with a significant improvement in homogeneity (~25%) with IMPT. Integral dose was reduced of ~60% with IMPT while the conformality of the dose distributions was similar among techniques. The sparing of the organs at risk was strongly improved with IMPT although all clinical objectives were met for both techniques. The inclusion of the uncertainties in the optimization lead to some deterioration in the target dose homogeneity (from 40 to 80% worse with 4 or 6mm position uncertainty) while none of the coverage parameters or OAR objective was violated. The worst-case scenario analysis demonstrated the risk of a major target underdosage only in the case of the most extreme errors (6mm) with D98% in average ~12% lower than the threshold.</p> <p>CONCLUSION:</p> <p>IMPT with the support of abdominal compression, can be considered a viable solution also for advanced hepatocellular carcinoma patients. Great care shall be put in the minimization of the residual respiration and positioning uncertainties but the dosimetric advantage for organs at risk and the relative robustness on target coverage are promising factors.</p> <p> </p>

<p>This record contains raw data related to article "Long-term outcomes of high-grade T1 bladder cancer treated with intravesical bacillus Calmette-Guérin: experience of a single center"</p> <p>BACKGROUND:</p> <p>To assess the outcomes of patients with high-grade (HG) pT1 bladder cancer (BC) treated with intravesical BCG therapy.</p> <p>METHODS:</p> <p>The study population consisted of 185 patients with HG pT1 BC treated between 1998 and 2010. We aimed to determine recurrence-free (RFS) and progression-free survival (PFS), as well as the predictors of RFS and PFS.</p> <p>RESULTS:</p> <p>Overall, 143 (77.3%) patients were males. Median age was 72 years (IQR: 66-78). Tumor size was ≥3 cm in 100 (54.1%) individuals. Most patients had single tumors (125; 67.6%). Primary, progressive and recurrent patterns of presentation were observed in 146 (78.9%), 21 (11.4%), and 18 (9.7%) cases, respectively. After 2nd-look TURB, 127 (68.6%) patients had no residual disease, 44 (23.8%) had Ta/CIS, and 14 (7.6%) had T1 HG BC. Twenty-two (11.9%) patients experience early recurrence after BCG. Of these, 12 patients (54.5%) were diagnosed with Ta/CIS, while 10 (45.5%) were diagnosed with HG pT1 BC. The median follow-up was 93 months (IQR: 63-147). Ten-year RFS and PFS rates were 69.6 and 79.2%. In multivariable Cox regression models, female gender (HR=2.41; P=0.001), progressive (HR=2.03; P=0.030) and recurrent (HR=3.87; P<0.001) pattern of presentation emerged as independent predictors of RFS, while age ≥70 years (HR=2.13; P=0.027), presence of multiple tumors (HR=2.06; P=0.019), and early recurrence (HR=3.88; P<0.001) emerged as independent predictors of PFS.</p> <p>CONCLUSIONS:</p> <p>Intravesical BCG appears to be an effective treatment for HG pT1 BC. Caution should be used in patients aged ≥70 years, with multiple tumors or experiencing early recurrence.</p>
Dataset related to article "Stereotactic Body Radiation Therapy in Oligometastatic Ovarian Cancer A Promising Therapeutic Approach"
<p>This record contains raw data related to article "Stereotactic Body Radiation Therapy in Oligometastatic Ovarian Cancer A Promising Therapeutic Approach"</p> <p>OBJECTIVE:</p> <p>Stereotactic body radiation therapy (SBRT) has been successfully used to treat oligometastases of several primary tumors, but few experiences have been described in patients with gynecological oligometastatic cancer, particularly in ovarian neoplasm. The aim of this study was to evaluate the role of this new radiotherapy modality in a series of oligometastatic ovarian cancer patients.</p> <p>MATERIALS AND METHODS:</p> <p>Clinical records of patients affected by oligometastatic ovarian carcinoma treated with SBRT were reviewed.</p> <p>RESULTS:</p> <p>Twenty-six patients with 44 metastatic lesions (lymph nodes, 63.6%; liver, 31.8%; and lung, 4.5%) treated with SBRT between January 2011 and May 2017 were analyzed. After a median follow-up period of 28.5 months (range, 6-86 months), 17 patients (65.4%) were still alive at time of analysis: 6 are without evidence of disease, 11 experienced a disease progression. Eight patients died of disease, 1 died because of an heart attack while being disease free. The median local control (LC) was not reached. One-, 2-, and 5-year LCs were 92.9%. Median progression-free survival was 19 months, with 1-year progression-free survival of 69.3% and 38% at 2 years, 19% at 5 years. Median overall survival was 64.5 months, with all patients alive after 1 year, 92.7% at 2 years, and 61.7% at 5 years. Five (11.3%) cases experienced G2 toxicity; most common adverse effect was nausea and vomiting (3 cases [6.8%]) followed by abdominal pain (2 cases [4.5%]). None of the patients had grade 3 or grade 4 acute or late toxicity.</p> <p>CONCLUSIONS:</p> <p>In conclusion, SBRT is a feasible and safe approach for selected cases of oligometastatic ovarian cancer, with satisfactory results in terms of LC and disease free survival.</p> <p> </p>
Dataset related to article "High-dimensional single cell analysis identifies stem-like cytotoxic CD8+ T cells infiltrating human tumors"
<p>This record contains raw data related to article "High-dimensional single cell analysis identifies stem-like cytotoxic CD8+ T cells infiltrating human tumors"</p> <p>CD8<sup>+</sup> T cells infiltrating tumors are largely dysfunctional, but whether a subset maintains superior functionality remains ill defined. By high-dimensional single cell analysis of millions of CD8<sup>+</sup> T cells from 53 individuals with lung cancer, we defined those subsets that are enriched in tumors compared with cancer-free tissues and blood. Besides exhausted and activated cells, we identified CXCR5<sup>+</sup> TIM-3<sup>-</sup> CD8<sup>+</sup> T cells with a partial exhausted phenotype, while retaining gene networks responsible for stem-like plasticity and cytotoxicity, as revealed by single cell sequencing of the whole transcriptome. Ex vivo, CXCR5<sup>+</sup> TIM-3<sup>-</sup> CD8<sup>+</sup> T cells displayed enhanced self-renewal and multipotency compared with more differentiated subsets and were largely polyfunctional. Analysis of inhibitory and costimulatory receptors revealed PD-1, TIGIT, and CD27 as possible targets of immunotherapy. We thus demonstrate a hierarchy of differentiation in the context of T cell exhaustion in human cancer similar to that of chronically infected mice, which is further shown to disappear with disease progression.</p>
Dataset related to article "Tumor heterogeneity, hypoxia, and immune markers in surgically resected non-small-cell lung cancer"
<p>This record contains raw data related to article "Tumor heterogeneity, hypoxia, and immune markers in surgically resected non-small-cell lung cancer"</p> <p>OBJECTIVES:</p> <p>This study aimed to determine the prognostic role of textural features and their association with metabolic parameters, hypoxia, and cancer-related immune markers in non-small-cell lung cancer (NSCLC) patients.</p> <p>PATIENTS AND METHODS:</p> <p>The trial was registered at http://www.clinicaltrials.gov (<a href="http://clinicaltrials.gov/show/NCT02519062">NCT02519062</a>). From January 2010 to May 2014, 44 patients (male : female=33 : 11; median age: 69.5 years), referred to our Institution for NSCLC resection, were enrolled. Tumor specimens were assessed for HIF-1α, CD68-TAMs, CD8-TILs, PD-1-TILs, and PD-L1 expressions. All patients underwent fluorine-18-fluorodeoxyglucose (F-FDG) PET before surgery. Semiquantitative parameters included maximum standardized uptake value (SUVmax), SUVpeak, SUVmean, metabolic tumor volume, and total lesion glycolysis, whereas for heterogeneity, we considered tumor sphericity, skewness, kurtosis, entropy, and energy. Parameters were correlated with disease-free survival (DFS) considering a median follow-up of 22.7 months.</p> <p>RESULTS:</p> <p>SUVmax (cutoff: 7.9; P=0.015), SUVpeak (cutoff: 6.7; P=0.013), SUVmean (cutoff: 5.5; P=0.028), metabolic tumor volume (cutoff: 3.6 cm; P=0.027), and entropy (cutoff: 1.89; P=0.045) showed a statistically significant association with DFS. Also, a high expression of cytoplasmic HIF-1α (score 3) was associated with DFS (hazard ratio: 0.09; P=0.003). All F-FDG PET variables differed significantly in tumors with high or low entropy (≤1.89). Also, a significantly higher level of mean CD8-TILs was observed in tumors with higher entropy (P=0.041).Using identified prognostic factors, we developed a scoring system, which was confirmed to be associated with DFS (P<0.004). On receiver operating characteristics analysis, a score above 3 was defined as the optimal cutoff point.</p> <p>CONCLUSION:</p> <p>Tumor heterogeneity, metabolic parameters, and high expression of hypoxia were found to be prognostic factors in NSCLC patients who were candidates for surgery. Higher levels of entropy appear to be associated with increased density of CD8-TILs. The combination of investigated prognostic factors enabled the development of a potential scoring system associated with DFS</p>
Dataset related to article "Protumor steering of cancer inflammation by p50 nf-kb enhances colorectal cancer progression"
<p>This record contains raw data related to article "Protumor steering of cancer inflammation by p50 nf-kb enhances colorectal cancer progression"</p> <p>Although tumor-associated macrophages (TAM) display a M2-skewed tumor-promoting phenotype in most cancers, in colorectal cancer, both TAM polarization and its impact remain controversial. We investigated the role of the M2-polarizing p50 NF-κB subunit in orchestrating TAM phenotype, tumor microenvironment composition, and colorectal cancer progression. We first demonstrated, by parallel studies in colitis-associated cancer (CAC) and in genetically driven Apc<sup>Min</sup> mouse models, that the p50-dependent inhibition of M1-polarized gut inflammation supported colorectal cancer development. In accordance with these studies, p50<sup>-/-</sup> mice displayed exacerbated CAC with fewer and smaller tumors, along with enhanced levels of M1/Th1 cytokines/chemokines, including IL12 and CXCL10, whose administration restrained CAC development <em>in vivo</em> The inflammatory profile supporting tumor resistance in colons from p50<sup>-/-</sup> tumor bearers correlated inversely with TAM load and positively with both recruitment of NK, NKT, CD8<sup>+</sup> T cells and number of apoptotic tumor cells. In agreement, myeloid-specific ablation of p50 promoted tumor resistance in mice, whereas in colorectal cancer patients, a high number of p50<sup>+</sup> TAMs at the invasive margin was associated with decreased <em>IL12A</em> and <em>TBX21</em> expression and worse postsurgical outcome. Our findings point to p50 involvement in colorectal cancer development, through its engagement in the protumor activation of macrophages, and identify a candidate for prognostic and target therapeutic intervention. <em>Cancer Immunol Res; 6(5); 578-93. ©2018 AACR</em>.</p> <p> </p>

Dataset related to article "Hypofractionated volumetric modulated arc therapy in ductal carcinoma in situ Toxicity and cosmetic outcome from a prospective series"
<p>This record contains raw data related to article "Hypofractionated volumetric modulated arc therapy in ductal carcinoma in situ Toxicity and cosmetic outcome from a prospective series"</p> <p>O</p> <p>BJECTIVE:</p> <p>Hypofractionated radiotherapy in early stage breast cancer is an effective adjuvant treatment, but there is a lack of randomized data for patients with ductal carcinoma in situ (DCIS). The aim of this study is the evaluation of skin toxicity and cosmesis, and early clinical outcome of DCIS patients enrolled in an institutional Phase II trial of hypofractionated breast irradiation.</p> <p>METHODS:</p> <p>137 DCIS patients were enrolled in the trial. All patients underwent volumetric modulated arc therapy (VMAT) to the whole breast with a total dose of 40.5 Gy in 15 fractions over 3 weeks, without tumour bed boost. Acute and late skin toxicities were recorded. Cosmetic outcomes were assessed as excellent/good or fair/poor. Early clinical outcome was reported.</p> <p>RESULTS:</p> <p>Median age was 58 y.o. (range 30-86). The median follow-up time was 22 months (range 6-45). At the end of the radiotherapy, skin toxicity was grade G1 in 56% of the patients, G2 in 15%, no patients presented G3 toxicity. In the range of 3-9 months of follow-up, the skin toxicity was G1 in 28% of patients, no G2-G3 cases; cosmetic outcome was good/excellent in 95% of patients. In the follow-up interval of 9-24 months, the skin toxicity was G1 in 12% of patients, no G2-G3 toxicity; cosmetic outcome was good/excellent in 96% of patients. After an early evaluation of clinical outcomes, 5 patients (3.6%) presented an in-breast recurrence.</p> <p>CONCLUSION:</p> <p>Hypofractionated radiotherapy using VMAT is a viable option for DCIS. A longer follow-up is needed to assess clinical outcomes and late toxicity. Advances in knowledge: The use of hypofractionated VMAT is dosimetrically feasible for treating breast DCIS.</p> <p> </p>

<p>This record contains raw data related to article ""EUS elastography (strain ratio) and fractal-based quantitative analysis for the diagnosis of solid pancreatic lesions</p> <p>EUS elastography is useful in characterizing solid pancreatic lesions (SPLs), and fractal analysis-based technology has been used to evaluate geometric complexity in oncology. The aim of this study was to evaluate EUS elastography (strain ratio) and fractal analysis for the characterization of SPLs.</p> <p>METHODS:</p> <p>Consecutive patients with SPLs were prospectively enrolled between December 2015 and February 2017. Elastographic evaluation included parenchymal strain ratio (pSR) and wall strain ratio (wSR) and was performed with a new compact US processor. Elastographic images were analyzed using a computer program to determine the 3-dimensional histogram fractal dimension. A composite cytology/histology/clinical reference standard was used to assess sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating curve.</p> <p>RESULTS:</p> <p>Overall, 102 SPLs from 100 patients were studied. At final diagnosis, 69 (68%) were malignant and 33 benign. At elastography, both pSR and wSR appeared to be significantly higher in malignant as compared with benign SPLs (pSR, 24.5 vs 6.4 [P < .001]; wSR, 56.6 vs 15.3 [P < .001]). When the best cut-off levels of pSR and wSR at 9.10 and 16.2, respectively, were used, sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating curve were 88.4%, 78.8%, 89.7%, 76.9%, and 86.7% and 91.3%, 69.7%, 86.5%, 80%, and 85.7%, respectively. Fractal analysis showed a significant statistical difference (P = .0087) between the mean surface fractal dimension of malignant lesions (D = 2.66 ± .01) versus neuroendocrine tumor (D = 2.73 ± .03) and a statistical difference for all 3 channels red, green, and blue (P < .0001).</p> <p>CONCLUSIONS:</p> <p>EUS elastography with pSR and fractal-based analysis are useful in characterizing SPLs.</p>
Dataset related to article "Role of Stereotactic Body Radiation Therapy for the Management of Oligometastatic Renal Cell Carcinoma"
<p>This record contains raw data related to article "Role of Stereotactic Body Radiation Therapy for the Management of Oligometastatic Renal Cell Carcinoma"</p> <p>PURPOSE: Kidney cancer has been increasing 1.7% annually. Renal cell carcinoma is the most common kidney cancer and it can metastasize. Our aim was to analyze patients treated with stereotactic body radiation therapy of renal cell carcinoma metastases.</p> <p>MATERIALS AND METHODS:</p> <p>A total of 58 patients (73 lesions) were treated from 2004 to 2016. Patients were candidates for analysis if a maximum of 3 metastases were diagnosed and the primary tumor was resected. Toxicity was classified according to Common Terminology Criteria for Adverse Events version 3.</p> <p>RESULTS:</p> <p>All patients had renal cell carcinoma, in particular the clear cell type in 82.7%. A total of 39 metastases (53.4%) were located in the lungs and 19 (26%) were in the lymph nodes. Less common were metastases to bone (9.5% of cases), the liver (4.1%) and the adrenal gland (6.8%). Median followup was 16.1 months (range 3.5 to 157.1). The local control rate at 12 and 18 months was 90.2% and 90.2%, respectively. The progression-free survival rate at 12 and 18 months was 46.2% (95% CI 32.2-59) and 35% (95% CI 21.4-48.9), respectively. On univariate and multivariable analyses metachronous and single metastases predicted better progression-free survival. Systemic therapy before stereotactic body radiation therapy predicted improved local control in clear cell cases.</p> <p>CONCLUSIONS:</p> <p>Stereotactic body radiation therapy can be considered a safe approach and it provides effective local control of oligometastatic renal cell carcinoma. However, future prospective studies are necessary to evaluate the impact on survival and quality of life.</p>
Dataset related to article "Role of 11 C-choline PET/CT in radiation therapy planning of patients with prostate cancer"
<p>This record contains raw data related to article "Role of 11 C-choline PET/CT in radiation therapy planning of patients with prostate cancer"</p> <p>BACKGROUND:</p> <p>In the era of image-guided radiotherapy, PET has become an important tool for tumor delineation in several types of cancer. The aim of this study was to evaluate the effect of this imaging modality in treatment planning of a cohort of patients with prostate cancer eligible for radiotherapy.</p> <p>METHODS:</p> <p>From September 2011 to January 2016, 135 consecutive patients (median age 69 years, range: 53-89) were referred to our department for radiation therapy with radical intent (n=28), for postoperative adjuvant (n=13) or salvage treatment (n=50), for re-irradiation (n=19), or for radiotherapy on oligometastases (n=25). Before planning the radiotherapy course, patients were submitted to carbon-11-choline PET (Cho-PET) to confirm the indication to radiotherapy and the irradiation volumes.</p> <p>RESULTS:</p> <p>Among the 135 patients subjected to Cho-PET, the indication to radiotherapy was modified in 66 (48.8%) cases based on the Cho-PET result. In particular, Cho-PET helped to better define the radiotherapy programme in 12 out of 28 (42.8%) patients who were candidates for primary radiation therapy, 33 (52.4%) of 63 patients undergoing adjuvant/salvage radiotherapy, and 21 out of 44 (47.7%) patients with relapsed/metastatic disease. Overall biochemical response is documented by mean and median prostate specific antigen values, which changed from 15.29 to 4.00 ng/ml, respectively, before to mean 4.74 ng/ml and median 0.81 ng/ml after therapy (P=0.05).</p> <p>CONCLUSION:</p> <p>In our series, Cho-PET had a significant effect on radiotherapy planning of patients affected by prostate cancer, determining a change in management in 48.8% of cases, considering all therapeutic indications</p>
Database article Developing Sustainable Career Paths for Preuniversity Teachers. An Empirical Analysis of Central Dimensions of Job Readiness
<p>The quality of teacher training is highly likely to influence the quality of learning outcomes. In this view, the present paper aimed to develop a pre-service teachers’ job readiness model integrating individual variables associated with teacher professionalism. The study followed an exploratory cross-sectional research design. A sample of 312 Romanian pre-service STEM (Science, Technology, Engineering, and Mathematics) teachers was selected based on availability criteria. A pre-tested self-administered questionnaire using a 5-point Likert scale was applied during the data collection process. Data analysis was based on a combination of descriptive and inferential statistics, a blending factor analysis and structural equations modeling. A conceptual model of teaching readiness from the teacher professionalism perspective was developed and tested using empirical data. The results suggest that professional knowledge, professional practice, professional engagement and self-management could be considered central dimensions of teacher professionalism, being highly relevant in assessing pre-service teacher job readiness. Moreover, professional knowledge has a strong and positive influence on teaching practice and professional engagement. In relation to the professional knowledge latent variable, the ability to conduct didactic transposition is the most influential. Following the same line of analysis, the most significant vectors of the professional practice variable were found to be the ability to design effective evaluation tools and to analyze and interpret learning outcomes. The research revealed the presence of vulnerable or sensitive areas of teacher training that could be a result of curriculum design. With respect to managing disruptive behaviours, the customization of learning and emotional self-regulation are considered weak areas of teaching readiness. The results could be useful for policymakers and teacher training practitioners in order to improve overall job readiness and teacher professionalism.</p>
