Cabozantinib After a Previous Immune Checkpoint Inhibitor in Metastatic Renal Cell Carcinoma: A Retrospective Multi-Institutional Analysis

Background: Angiogenesis has been recognized as the most important factor for tumor invasion, proliferation, and progression in metastatic renal cell carcinoma (mRCC). However, few clinical data are available regarding the efficacy of cabozantinib following immunotherapy. Objective: To describe the outcome of cabozantinib in patients previously treated with immunotherapy. Patients and methods: Patients with mRCC who received cabozantinib immediately after nivolumab were included. The primary endpoint was to assess the outcome in terms of efficacy and activity. Results: Eighty-four mRCC patients met the criteria to be included in the final analysis. After a median follow-up of 9.4 months, median overall survival was 17.3 months. According to the IMDC criteria, the rates of patients alive at 12 months in the good, intermediate, and poor prognostic groups were 100%, 74%, and 33%, respectively (p < 0.001). The median progression-free survival (PFS) was 11.5 months (95% CI 8.3-14.7); no difference was found based on duration of previous first-line therapy or nivolumab PFS. The overall response rate was 52%, stable disease was found as the best response in 25.3% and progressive disease in 22.7% of patients. Among the 35 patients with progressive disease on nivolumab, 26 (74.3%) patients showed complete/partial response or stable disease with cabozantinib as best response after nivolumab. The major limitations of this study are the retrospective nature and the short follow-up. Conclusions: Cabozantinib was shown to be effective and active in patients previously receiving immune checkpoint inhibitors. Therefore, cabozantinib can be considered a valid therapeutic option for previously treated mRCC patients, irrespective of the type and duration of prior therapies

Predictors of long-term response to abiraterone in patients with metastastic castration-resistant prostate cancer: a retrospective cohort study

We aimed to identify clinical predictors of long-term response to abiraterone (defined as >12 months drug exposure) in a retrospective cohort of metastatic castration-resistant prostate cancer patients treated in post-docetaxel setting at 24 Italian centers. The Cox proportional hazards model was used to analyze the association between clinical features and the duration of drug exposure. Results were expressed as hazard ratios (HR) with associated 95% confidence intervals (CI). A total of 143 patients met the inclusion criteria. Their median age was 73 years, median Gleason score 8 and median abiraterone exposure 20 months. At the univariate analysis, a significant correlation with the duration of abiraterone exposure was found for Gleason score (HR 0.82, 95% CI 0.71-0.96; p=0.012), PSA (HR 1.10, 95% CI 1.03-1.18; p=0.08) and lactic dehydrogenase levels (HR 1.22, 95% CI 1.02-1.46; p=0.027), while the association between lower alkaline phosphatase levels and treatment duration was marginally significant (HR 1.07, 95% CI 0.99-1.16; p=0.074). Only PSA and Gleason score were predictive of long-term treatment duration in the multivariate analysis. No other clinical factors resulted to be predictive of sustained response to abiraterone, including metastatic disease at diagnosis and visceral disease, suggesting that all subgroups of patients may derive a substantial clinical benefit from abiraterone treatment. These findings need to be validated in prospective, larger studies

The prognostic value of the previous nephrectomy in pretreated metastatic renal cell carcinoma receiving immunotherapy: a sub-analysis of the Meet-URO 15 study

Nephrectomy is considered the backbone of managing patients with localized and selected metastatic renal cell carcinoma (mRCC). The prognostic role of nephrectomy has been widely investigated with cytokines and targeted therapy, but it is still unclear in the immunotherapy era

SARS-CoV-2 vaccination modelling for safe surgery to save lives : data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population.Peer reviewe

Going Online While Purchasing Offline: an Explorative Analysis of Omnichannel Shopping Behaviour in Retail Settings

Retail customers are now omnichannel both for attitude and behaviour. Shoppers are also demanding a different and higher level of experience within retailer’s brand, channel, contact point and the way in which the retail is accessed. Such shoppers avoid retailers who are ill-equipped to deliver a seamless brand experience online, in-store and across multichannel media, both consistently and continuously (PwC & Kantar Retail, 2012). Therefore, a new and improved strategy aimed at delivering information and product to customers is becoming mandatory for retailers. Recently some retailers are showing an increasing interest in the application of advanced systems developed to enhance the shopping experience by providing customers with innovative tools able to engage them with multiple channels simultaneously to obtain deeper insights, save time and feel more independent while shopping. Such technologies can help retailers to better react to those emerging settings by (i) acquiring a positive image and reputation, being at the same time perceived as innovator; (ii) reducing management costs; (iii) maintaining and acquiring loyal consumers; (iv) making imitation strategies as difficult as possible for competitors; (v) reaching a unique and differentiated positioning. Consequently, many retailers have recently introduced advanced technologies in their stores such as self-service technologies equipped with radio frequency identification systems (RFID), interactive touch screen displays, digital signage and mobile applications, informative touch points and contactless technologies for mobile payments. Furthermore, the development of ubiquitous computing allowed companies to create virtual stores based on QR tags which can be located everywhere and enable consumers to purchase by their mobile devices. These technologies modify both consumer behavior and corporate approach to retail process, by changing the way customers access to information and firms reach their customers. Since individuals interact with multiple channels throughout their shopping journey, even simultaneously (Omnichannel Retailing), retailers must consider all channels holistically as consumers do, in order to provide them with a unified shopping experience. Preliminary result of our multiple case study involving 15 retailers, operating in different industries of the Italian market, shows that customers are increasingly willing to use the in-store innovations in order to obtain richer shopping experiences, while retailers achieve a stronger brand loyalty as well as a better and updated brand image. A deeper understanding of positive effects and threats resulting from early technology adoption by retailers will be essential for improving the omnichannel customer management, thus increasing business performance

Reverse Engineering and Redesign of the Impeller of a Submersible Centrifugal Pump

In this work a Reverse Engineering based approach has been implemented aiming to reconstruct the 3D shape of a strongly damaged and no longer usable impeller of a submersible centrifugal pump. After obtaining the 3D model, new designs of the impeller were investigated in terms of structural stability and corrosion resistance by changing the geometry and the material. Obtained results show the used approach can be very useful both to reproduce, by Additive Manufacturing, no longer available spare parts, so allowing to extend the useful life of old machineries and to reduce costs resulting from plant shutdowns, but also to improve the performances of old designs, making use of different materials and new manufacturing processes

Sicurezza in città: pratiche di controllo all'interno dello spazio urbano

Sia all'interno del dibattito accademico che della retorica politica si discute molto di sicurezza urbana. Ciononostante, resta ancora da esplorare in che modo la “sicurezza urbana” possa differen­ziarsi da altre forme di sicurezza. Questo volume serve a porre le basi per analisi e studi futuri che abbiano l'obiettivo specifico di comprendere se, e quando, i contesti cittadini influenzino il fenomeno della sicurezza, al punto tale da doverla declinare nella sua accezione “urbana”. Gli autori dei saggi hanno cercato di rispondere ad una o più delle seguenti domande: in che modo il contesto urbano determina le espressioni più visibili e quelle meno facilmente individuabili di fenomeni quali criminalità, violenza, disordine e conflitto? Quali sono gli attori sociali che, all'interno delle città, influenzano maggiormente le pratiche di controllo per contrastare o diminuire tali fenomeni? Quali conflitti sociali emergono come conseguenza diretta delle pratiche di controllo dispiegate dentro le città? Nel fare ciò, ogni saggio prende in considerazione le specificità delle città in analisi per spiegare come queste determinano ed influenzano tali pratiche di controllo

An Olive Oil Mill Wastewater Extract Improves Chemotherapeutic Activity Against Breast Cancer Cells While Protecting From Cardiotoxicity

Cardiovascular toxicity in cancer patients receiving chemotherapy remains one of the most undesirable side effects, limiting the choice of the most efficient therapeutic regimen, including combinations of different anticancer agents. Anthracyclines (doxorubicin) and antimetabolites (5-fluorouracil (5-FU), capecitabine) are among the most known agents used in breast cancer and other neoplasms and are associated with cardiotoxic effects. Extra-virgin olive oil (EVOO) is rich in polyphenols endowed with antioxidant cardioprotective activities. Olive mill wastewater (OMWW), a waste product generated by EVOO processing, has been reported to be enriched in polyphenols. In this study, we investigated the activities of polyphenol-rich extract from OMWW, A009, in cooperation with chemotherapy on two breast cancer cell lines, namely, BT459 and MDA-MB-231, in a cardio-oncology perspective. The effects of A009 on cardiac cells were also investigated with and without chemotherapeutic agents. Cell viability was determined on BT459 and MDA-MB-231 (i.e., breast cancer cells) and H9C2 (i.e., rat cardiomyocytes) cells, using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. A spheroids assay was used as a 3D in vitro model on BT459 and MDA-MB-231 cells. For in vivo studies, the murine sponge assay of angiogenesis was used as a model of breast cancer-associated vascularization. The embryo of Danio rerio (zebrafish) was used to detect the cardioprotective activities of the OMWW. We found that the A009 extract exhibited antiangiogenic activities induced by breast cancer cell supernatants and increased T-cell recruitment in vivo. The combination of the OMWW extracts with doxorubicin or 5-FU limited BT459 and MDA-MB-231 cell viability and the diameter of 3D spheroids, while mitigating their toxic effects on the rat H9C2 cardiomyocytes. Cardioprotective effects were observed by the combination of OMWW extracts with doxorubicin in zebrafish embryos. Finally, in human cardio myocytes, we observed 5-FU-induced upregulation of the inflammatory, senescence-associated cytokine IL6 and p16 genes, which expression was reduced by OMWW treatment. Our study demonstrates that the polyphenol-rich purified OMWW extract A009 combined with cancer chemotherapy could represent a potential candidate for cardiovascular protection in breast cancer patients, while increasing the effects of breast cancer chemotherapy

Pegfilgrastim: Current and future perspectives in the treatment of chemotherapy-induced neutropenia

Myeloid colony-stimulating factors (granulocyte colony-stimulating factor [G-CSF] and granulocyte-macrophage colony-stimulating factor) are commonly used in clinical practice for the prevention of anticancer chemotherapy-induced neutropenia and its potentially life-threatening complications. Pegfilgrastim is a novel recombinant human G-CSF pharmaceutically developed by covalent binding of a polyethylene glycol molecule to the N-terminal sequence of filgrastim. Due to its unique neutrophil-mediated clearance, pegfilgrastim can be administered once per chemotherapy cycle. Clinical trials have demonstrated that a single, fixed, subcutaneous dose of pegfilgrastim is comparable in safety and efficacy to daily injections of filgrastim for decreasing the incidence of infection following myelosuppressive chemotherapy in patients with cancer. Recent trials have been conducted to evaluate the use of pegfilgrastim in different clinical settings, including support of dose-dense regimens, mobilization and transplantation of hematopoietic stem cells

Second-line treatment in renal cell carcinoma: clinical experience and decision making

Currently, conventional treatments for metastatic RCC (mRCC) include immune-based combination regimens and/or targeted therapies, the latter mainly acting on angiogenesis, a key element of the process of tumor growth and spread. Although these agents proved able to improve patients’ outcomes, drug resistance and disease progression are still experienced by a substantial number of VEGFR-TKIs-treated mRCC patients. Following the inhibition of the VEGF/VEGFRs axis, two strategies have emerged: either specifically targeting resistance pathways, at the same time continuing to inhibit angiogenesis, or using a completely different approach aimed at re-activating the immune system through the use of inhibitors of specific negative immune checkpoints. These two approaches, practically represented by the use of either cabozantinib or nivolumab, seem to remain a rational therapeutic approach also when first-line immune-based combinations are used. The objective of this study is to design a preferential therapeutic pathway for the second-line treatment of mRCC. The procedure applied in this project was a group discussion, based on the Nominal Group Technique (NGT) method in a meeting session, aimed at defining the therapeutic choice for the second-line treatment of mRCC. The NGT process defined the most relevant parameters that, according to the interviewed panelists, clinicians should consider for the selection of the second-line therapy in the context of advanced renal cell carcinoma of mRCC. The algorithm developed for the treatment selection as a result of this process should thus be considered by clinicians as reference for therapy selection. Plain language summary The result of this paper was the definition of an algorithm intended to suggest a preferential therapeutic pathway considering both the outputs of the Nominal Group Technique (NGT) process and the actual clinical practice and the experience of selected panelists. During the NGT process and the discussion phase, panelists defined the most important parameters to be included in the algorithm that are important for the treatment definition. Cabozantinib and nivolumab are identified as the most reasonable therapeutic options for patients progressing after first-line treatment and are the medication options included in the algorithm for therapy selection
