Quality of life in patients with metastatic prostate cancer following treatment with cabazitaxel versus abiraterone or enzalutamide (CARD): an analysis of a randomised, multicentre, open-label, phase 4 study.

Background: In the CARD study, cabazitaxel significantly improved radiographic progression-free survival and overall survival versus abiraterone or enzalutamide in patients with metastatic castration-resistant prostate cancer previously treated with docetaxel and the alternative androgen signalling-targeted inhibitor. Here, we report the quality-of-life outcomes from the CARD study.

Methods: CARD was a randomised, multicentre, open-label, phase 4 study involving 62 clinical sites across 13 European countries.

Adverse event management in the TOURMALINE-MM3 study of post-transplant ixazomib maintenance in multiple myeloma.

The phase 3, double-blind, placebo-controlled TOURMALINE-MM3 study (NCT02181413) demonstrated improved progression-free survival with ixazomib maintenance versus placebo post autologous stem cell transplant (ASCT) in multiple myeloma patients. We report additional safety data from TOURMALINE-MM3 to inform adverse event (AE) management recommendations. Patients were randomized 3:2 to receive ixazomib (n = 395) or placebo (n = 261) on days 1, 8, and 15 of 28-day cycles for ~ 2 years or until progressive disease/toxicity.

Lenalidomide before and after autologous stem cell transplantation for transplant-eligible patients of all ages in the randomized, phase III, Myeloma XI trial.

The optimal way to use immunomodulatory drugs as components of induction and maintenance therapy for multiple myeloma is unresolved. We addressed this question in a large phase III randomized trial, Myeloma XI. Patients with newly diagnosed multiple myeloma (n = 2042) were randomized to induction therapy with cyclophosphamide, thalidomide, and dexamethasone (CTD) or cyclophosphamide, lenalidomide, and dexamethasone (CRD).

Young patients with cancer and a digital social network: the voice beyond the clinic.

Introduction: Digital social networks have become a key player in the ecosystem of young patients with cancer, with regard to their unique perspectives and unmet needs. This study aims to investigate the web-based social community tools and to characterise the user profile, unmet needs and goals of young patients with cancer.

Methods: A web-based survey was distributed via large-scale social network designated for young patients with cancer (age 18-45 years) Stop Cancer.

Exploiting evolutionary steering to induce collateral drug sensitivity in cancer.

Drug resistance mediated by clonal evolution is arguably the biggest problem in cancer therapy today. However, evolving resistance to one drug may come at a cost of decreased fecundity or increased sensitivity to another drug. These evolutionary trade-offs can be exploited using 'evolutionary steering' to control the tumour population and delay resistance.

Development and application of two novel monoclonal antibodies against overexpressed CD26 and integrin α3 in human pancreatic cancer.

Monoclonal antibody (mAb) technology is an excellent tool for the discovery of overexpressed cell surface tumour antigens and the development of targeting agents. Here, we report the development of two novel mAbs against CFPAC-1 human pancreatic cancer cells. Using ELISA, flow cytometry, immunoprecipitation, mass spectrometry, Western blot and immunohistochemistry, we found that the target antigens recognised by the two novel mAbs KU44.

Cabazitaxel versus Abiraterone or Enzalutamide in Metastatic Prostate Cancer.

Background: The efficacy and safety of cabazitaxel, as compared with an androgen-signaling-targeted inhibitor (abiraterone or enzalutamide), in patients with metastatic castration-resistant prostate cancer who were previously treated with docetaxel and had progression within 12 months while receiving the alternative inhibitor (abiraterone or enzalutamide) are unclear.

Methods: We randomly assigned, in a 1:1 ratio, patients who had previously received docetaxel and an androgen-signaling-targeted inhibitor (abiraterone or enzalutamide) to receive cabazitaxel (at a dose of 25 mg per square meter of body-surface area intravenously every 3 weeks, plus prednisone daily and granulocyte colony-stimulating factor) or the other androgen-signaling-targeted inhibitor (either 1000 mg of abiraterone plus prednisone daily or 160 mg of enzalutamide daily). The primary end point was imaging-based progression-free survival.

Validated imaging biomarkers as decision-making tools in clinical trials and routine practice: current status and recommendations from the EIBALL* subcommittee of the European Society of Radiology (ESR).

Observer-driven pattern recognition is the standard for interpretation of medical images. To achieve global parity in interpretation, semi-quantitative scoring systems have been developed based on observer assessments; these are widely used in scoring coronary artery disease, the arthritides and neurological conditions and for indicating the likelihood of malignancy. However, in an era of machine learning and artificial intelligence, it is increasingly desirable that we extract quantitative biomarkers from medical images that inform on disease detection, characterisation, monitoring and assessment of response to treatment.

Synchrotron Microbeam Radiation Therapy as a New Approach for the Treatment of Radioresistant Melanoma: Potential Underlying Mechanisms.

Purpose: Synchrotron microbeam radiation therapy (MRT) is a method that spatially distributes the x-ray beam into several microbeams of very high dose (peak dose), regularly separated by low-dose intervals (valley dose). MRT selectively spares normal tissues, relative to conventional (uniform broad beam [BB]) radiation therapy.

Methods And Materials: To evaluate the effect of MRT on radioresistant melanoma, B16-F10 murine melanomas were implanted into mice ears.

First clinical real-time motion-including tumor dose reconstruction during radiotherapy delivery.

Purpose: To clinically implement and characterize real-time motion-including tumor dose reconstruction during radiotherapy delivery.

Methods: Seven patients with 2-3 fiducial markers implanted near liver tumors received stereotactic body radiotherapy on a conventional linear accelerator. The 3D marker motion during a setup CBCT scan was determined online from the CBCT projections and used to generate a correlation model between tumor and external marker block motion.

Cabozantinib for Progressive Metastatic Castration-resistant Prostate Cancer Following Docetaxel: Combined Analysis of Two Phase 3 Trials.

Two phase 3 trials, COMET-1 and COMET-2, have reported that cabozantinib did not significantly extend overall survival (OS) compared to prednisone and prednisone plus mitoxantrone, respectively, in post-docetaxel patients with metastatic castration-resistant prostate cancer (mCRPC). We conducted a retrospective analysis of a combined data set from these trials to identify a benefit in subsets of patients according to prognostic risk factors. The prognostic ability of factors to predict survival was evaluated using Cox proportional hazards regression models.

Spect perfusion imaging versus CT for predicting radiation injury to normal lung in lung cancer patients.

Objectives: In non-small cell lung cancer (NSCLC) patients, to establish whether the fractional volumes of irradiated anatomic or perfused lung differed between those with and without deteriorating lung function or radiation associated lung injury (RALI).

Methods: 48 patients undergoing radical radiotherapy for NSCLC had a radiotherapy-planning CT scan and single photon emission CT lung perfusion imaging (Tc-labelled macroaggregate albumin). CT defined the anatomic and the single photon emission CT scan (co-registered with CT) identified the perfused (threshold 20 % of maximum) lung volumes.

MR guided high intensity focused ultrasound (MRgHIFU) for treating recurrent gynaecological tumours: a pilot feasibility study.

Objective: To assess the feasibility of targeting recurrent gynaecological tumours with MR guided high intensity focused ultrasound (MRgHIFU).

Methods: 20 patients with recurrent gynaecological tumours were prospectively scanned on a Philips/Profound 3 T Achieva MR/ Sonalleve HIFU system. Gross tumour volume (GTV) and planning target volume (PTV) were delineated on W and diffusion-weighted imaging (DWI).

Evaluation of organ motion-based robust optimisation for VMAT planning for breast and internal mammary chain radiotherapy.

Aims: In patients undergoing locoregional radiotherapy (RT) for breast cancer including the internal mammary chain (IMC), VMAT has been shown to be superior to tangential-field radiotherapy in terms of target coverage and minimising dose to heart and lungs. In this study we describe and validate organ motion-based robust optimisation for generating breast and locoregional lymph node VMAT plans that are robust to inter-fractional changes.

Materials And Methods: In this retrospective study of five patients with left-sided breast cancer requiring locoregional breast radiotherapy including the IMC, non-robust plans were generated in the nominal scenario (planning-CT) and corresponding robust plans were created by optimising over a range of simulated CTs representing worst-case scenario shape changes to the breast.

MRI commissioning of 1.5T MR-linac systems - a multi-institutional study.

Background: Magnetic Resonance linear accelerator (MR-linac) systems represent a new type of technology that allows for online MR-guidance for high precision radiotherapy (RT). Currently, the first MR-linac installations are being introduced clinically. Since the imaging performance of these integrated MR-linac systems is critical for their application, a thorough commissioning of the MRI performance is essential.

Physicians, paraproteins and progress: diagnosis and management of myeloma.

Myeloma outcomes have improved dramatically over the last decade as a result of novel therapies, several of which are now commonly continued to disease relapse. Physicians who do not work in haematology are therefore more likely than ever before to be consulted by a patient with myeloma, either for an unrelated condition or with a side effect of myeloma or its treatment. Myeloma is also the cancer most likely to be diagnosed in accident and emergency departments or by the acute physician and so an awareness of its presentation and management is especially important in these settings to enable early diagnosis and limit the morbidity associated with end organ damage.

A Phase II Study of Talazoparib after Platinum or Cytotoxic Nonplatinum Regimens in Patients with Advanced Breast Cancer and Germline Mutations (ABRAZO).

Purpose: To assess talazoparib activity in germline mutation carriers with advanced breast cancer.

Patients And Methods: ABRAZO (NCT02034916) was a two-cohort, two-stage, phase II study of talazoparib (1 mg/day) in germline mutation carriers with a response to prior platinum with no progression on or within 8 weeks of the last platinum dose (cohort 1) or ≥3 platinum-free cytotoxic regimens (cohort 2) for advanced breast cancer. Primary endpoint was confirmed objective response rate (ORR) by independent radiological assessment.

Sertoli-Leydig Cell Tumour and Mutation: A Case Report and Review of the Literature.

Sertoli-Leydig cell tumours of the ovary (SLCT) are rare tumours predominantly caused by mutations in the gene. We present a patient with a unilateral SLCT who had an underlying germline gene mutation. We discuss the underlying pathology, risks, and screening opportunities available to those with a mutation in this gene as SLCT is only one of a multitude of other tumours encompassing syndrome.

To Cycle or Fight-CDK4/6 Inhibitors at the Crossroads of Anticancer Immunity.

Dysregulation of cell division resulting in aberrant cell proliferation is a key hallmark of cancer, making it a rational and important target for innovative anticancer drug development. Three selective cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors are FDA and European Medicines Agency (EMA) approved for hormone receptor-positive/HER2-negative advanced breast cancer. A major emerging appreciation is that these inhibitors not only are cytostatic, but also play critical roles in the interaction between tumor cells and the host immune response.
