Transforming RNA-Seq Data to Improve the Performance of Prognostic Gene Signatures
2014
Gene expression measurements have successfully been used for building prognostic signatures, i.e for identifying a short list of important genes that can predict patient outcome. Mostly microarray measurements have been considered, and there is little advice available for building multivariable risk prediction models from RNA-Seq data. We specifically consider penalized regression techniques, such as the lasso and componentwise boosting, which can simultaneously consider all measurements and provide both, multivariable regression models for prediction and automated variable selection. However, they might be affected by the typical skewness, mean-variance-dependency or extreme values of RNA-…
Benign multicystic mesothelioma: A case report of recurrent disease in a young adult with familiarity for renal cell carcinoma
2019
Benign multi-cystic peritoneal mesothelioma (BMCM) is a very rare disease (about 150 cases observed). The aetiology is currently little-known, and the data collected, without having achieved conclusive re sults, identify two possible causes: neoplastic and reactive inflammatory. This case report refers to a recidivism of BCMC in a patient whose brother, few months before, underwent a left nephrectomy and right renal Radio Frequency Termo Ablation (RFTA) for bilateral papillary renal cell carcinoma. For the recurring trend, the onset in a male young patient without chronic inflammatory diseases evidence, the presence of a first degree relative with a rare carcinoma we supposed a neoplastic a…
ASSOCIATION OF AN ORGAN TRANSPLANT-BASED APPROACH WITH A DRAMATIC REDUCTION IN POSTOPERATIVE COMPLICATIONS FOLLOWING RADICAL NEPHRECTOMY AND TUMOR TH…
2019
Objectives: Our aim was to determine whether using an organ transplant-based(TB) approach reduces postoperative complications(PCs) following radical nephrectomy(RN) and tumor thrombectomy(TT) in renal cell carcinoma(RCC) patients with level II-IV thrombi. Methods: A total of 390(292 non-TB/98 TB) IRCC-VT Consortium patients who received no preoperative embolization/IVC filter were included. Stepwise linear/logistic regression analyses were performed to determine significant multivariable predictors of intraoperative estimated blood loss(IEBL), number blood transfusions received, and overall/major PC development within 30days following surgery. Propensity to receive the TB approach was contr…
Therapeutic vaccines for cancer: an overview of clinical trials
2014
The therapeutic potential of host-specific and tumour-specific immune responses is well recognized and, after many years, active immunotherapies directed at inducing or augmenting these responses are entering clinical practice. Antitumour immunization is a complex, multi-component task, and the optimal combinations of antigens, adjuvants, delivery vehicles and routes of administration are not yet identified. Active immunotherapy must also address the immunosuppressive and tolerogenic mechanisms deployed by tumours. This Review provides an overview of new results from clinical studies of therapeutic cancer vaccines directed against tumour-associated antigens and discusses their implications …
Predicting positive surgical margins in partial nephrectomy: A prospective multicentre observational study (the RECORd 2 project)
2020
PURPOSE: to evaluate clinical predictors of positive surgical margins (PSMs) in a large multicenter prospective observational study and to develop a clinic nomogram to predict the likelihood of PSMs after partial nephrectomy (PN). MATERIALS AND METHODS: We prospectively evaluated 4308 patients who had surgical treatment for renal tumors between January 2013 and December 2016 at 26 urological Italian Centers (RECORd 2 project). Two multivariable logistic models were evaluated to predict the likelihood of PSMs. Center caseload was dichotomized using a visual assessment adjusted for several predictors of PSMs. A nomogram predicting PSMs was developed. RESULTS: Overall, 2076 patients treated wi…
Validation of the 2009 TNM Version in a Large Multi-Institutional Cohort of Patients Treated for Renal Cell Carcinoma: Are Further Improvements Neede…
2010
Background: A new edition of the TNM was recently released that includes modifications for the staging system of kidney cancers. Specifically, T2 cancers were subclassified into T2a and T2b ( 10 cm), tumors with renal vein involvement or perinephric fat involvement were classified as T3a cancers, and those with adrenal involvement were classified as T4 cancers. Objective: Our aim was to validate the recently released edition of the TNM staging system for primary tumor classification in kidney cancer. Design, setting, and participants: Our multicenter retrospective study consisted of 5339 patients treated in 16 academic Italian centers. Intervention: Patients underwent either radical or part…
Cabozantinib in Pretreated Patients with Metastatic Renal Cell Carcinoma with Sarcomatoid Differentiation: A Real-World Study
2021
Background: Renal cell carcinoma with sarcomatoid differentiation is a highly aggressive form of kidney cancer. Objective: We aimed to analyze the outcomes of patients treated with cabozantinib for metastatic renal cell carcinoma with sarcomatoid features. Methods: We retrospectively collected data from 16 worldwide centers. Overall survival and progression-free survival were analyzed using Kaplan–Meier curves. Cox proportional models were used for univariate and multivariate analyses. Results: We collected data from 66 patients with metastatic sarcomatoid renal cell carcinoma receiving cabozantinib as second-line (51%) or third-line (49%) therapy. The median progression-free survival from …
Osteonecrosis of the Jaw in Patients With Metastatic Renal Cell Cancer Treated With Bisphosphonates and Targeted Agents: Results of an Italian Multic…
2015
Osteonecrosis of the jaw (ONJ) associated with the use of bisphosphonates has been rarely reported in metastatic renal cell cancer (RCC) patients. Since the introduction of combined therapies consisting of nitrogen-containing bisphosphonates (NBPs) and targeted agents, an increasing number of RCC patients were reported to develop ONJ, suggesting that therapeutic angiogenesis suppression might increase the risk of ONJ in NBPs users. We performed a multicenter retrospective study and reviewed literature data to assess the occurrence and to investigate the nature of ONJ in RCC patients taking NBPs and targeted agents. Nine Italian Centers contributed to the data collection. Patients with expos…
Osteonecrosis of the jaw (ONJ) in renal cell cancer patients after treatment including zoledronic acid or denosumab.
2014
Dear Editor, The paper by Henry et al. published by Supportive Care in Cancer comparing efficacy of denosumab versus zoledronic acid in patients with bone metastases of advanced solid tumours [1] comes to integrate the original reports of three pivotal large randomized phase 3 trials [2–4], the publication by Saad et al. about osteonecrosis of the jaw (ONJ) in those three trials [5], and the combined outcome analysis by Lipton et al. [6]. Henry et al. [1] reported outcomes of the single trial conducted on patients with solid tumours (except breast or prostate cancers, object of other two trials) [2, 3], excluding patients with multiple myeloma: This ad hoc analysis confirmed the superiority…
Prognostic Factors of Papillary Renal Cell Carcinoma: Results From a Multi-Institutional Series After Pathological Review
2009
We examined papillary renal cell carcinoma prognostic variables and validated the 2002 UICC TNM staging system in a multicenter analysis.From 10 urological institutions in Germany followup data were collected on a total of 675 patients with papillary renal cell carcinoma. Central pathological review was done to validate external histopathological diagnoses. The Kaplan-Meier method was used to derive cumulative cancer specific and overall survival, and the log rank test was used to compare the curves of 2 or more groups. For multivariate analysis of prognostic factors Cox regression analysis was done. All proportional hazard assumptions were systemically verified using the Grambsch-Therneau …
