Real-world Outcomes of Sequential Androgen-receptor Targeting Therapies with or Without Interposed Life-prolonging Drugs in Metastatic Castration-resistant Prostate Cancer

_Background:_ Cross resistance between androgen-receptor targeting therapies(ARTs) (abiraterone acetate plus prednisone [ABI + P] or enzalutamide [ENZ]) fortreatment of metastatic castration-resistant prostate cancer (mCRPC) may affectresponses to second ART (ART2). _Objective:_ To establish treatment duration and prostate-specific antigen (PSA)response of ART2 in real-world mCRPC patients treated with or without otherlife-prolonging drugs (LPDs; ie, docetaxel, cabazitaxel, or radium-223) betweenART1 and ART2. _Design, setting, and participants:_ Castration-resistant prostate cancer patients,diagnosed between 2010 and 2016 were retrospectively registered in Castra-tion-resistant Prostate Cancer Registry (CAPRI). Patients treated with both ARTswere clustered into two subgroups: ART1 > ART2 or ART1 > LPD > ART2

Health-related Quality of Life and Pain in a Real-world Castration-resistant Prostate Cancer Population: Results From the PRO-CAPRI Study in the Netherlands

Background: The purpose of this study was to determine generic, cancer-specific, and prostate cancer-specific health-related quality of life (HRQoL), pain and changes over time in patients with metastatic castration-resistant prostate cancer (mCRPC) in daily practice. Patients and Methods: PRO-CAPRI is an observational, prospective study in 10 hospitals in the Netherlands. Patients with mCRPC completed the EQ-5D, European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and Brief Pain Inventory-Short Form (BPI-SF) every 3 months and European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire-Prostate Cancer Module (EORTC QLQ-PR25) every 6 months for a maximum of 2 years. Subgroups were identified based on chemotherapy pretreatment. Outcomes were generic, cancer-specific, and prostate cancer-specific HRQoL and self-reported pain. Descriptive statistics were performed including changes over time and minimal important differences (MID) between subgroups. Results: In total, 151 included patients answered 873 questionnaires. The median follow-up from the start of the study was 19.5 months, and 84% were treated with at least 1 life-prolonging agent. Overall, patients were in good clinical condition (Eatern Cooperative Oncology Group performance status 0-1 in 78%) with normal baseline hemoglobin, lactate dehydrogenase, and alkaline phosphatase. At inclusion, generic HRQoL was high with a mean EQ visual analog score of 73.2 out of 100. The lowest scores were reported on role and physical functioning (mean scores of 69 and 76 of 100, respectively), and fatigue, pain, and insomnia were the most impaired domai

Promises and challenges of positron emission tomography for assessment of sarcoma in daily clinical practice.

Contains fulltext : 71333.pdf (publisher's version ) (Open Access)A correct histological diagnosis, careful staging and detection of tumour response to treatment are all crucial in the management of sarcomas. Imaging is important in all of these stages. Sarcomas have distinct biological and treatment-related features posing challenges for imaging. For example, size measurements may not adequately reflect response rates. Techniques which can measure tissue function rather than generate merely anatomical data such as positron emission tomography (PET) are rapidly gaining interest. We discuss the importance of imaging in different stages of patient management, emphasising the unique characteristics of sarcoma. Furthermore, we discuss the potential of PET for the various indications, focussing on therapy evaluation

Anti-angiogenic therapy, a new player in the field of sarcoma treatment

Item does not contain fulltextSarcomas encompass a heterogeneous family of mesenchymal malignancies. In metastatic disease improvement in outcome has been limited and there is a clear need for the development of new therapies. One potential target is angiogenesis, already an accepted target for treatment of more prevalent cancers. Multiple (pre)clinical studies focused on the role of angiogenesis and anti-angiogenic treatment in sarcomas. However, getting significant results is complicated due to the relatively small number of patients and the broad range of sarcoma subtypes. Recently, pazopanib has been approved for the treatment of advanced soft tissue sarcoma patients, which is an important step forward and paves the way for the introduction of anti-angiogenic treatment in sarcomas. However, more studies are needed to understand the biological mechanisms by which patients respond to angiogenic inhibitors and to detect markers of response. This review covers the knowledge that has been gained on the role of angiogenesis and anti-angiogenic therapy in sarcomas

Clinical applications of positron emission tomography in sarcoma management

Item does not contain fulltextPositron emission tomography (PET) with the fluorine-18-labeled glucose analog FDG is a technique that noninvasively visualizes glucose metabolism in the human body. In oncology, the addition of FDG-PET to the conventional anatomical imaging techniques provides very useful clinical information in diagnosis, staging, treatment response monitoring and follow-up. In the heterogeneous group of patients with sarcoma, FDG-PET has been shown to be of great value in improving patient care. In this article we will discuss the current role of FDG-PET in the management of patients with sarcoma and its value in assessing tumor grade, guiding biopsy, staging, monitoring treatment response, restaging and prognostication. Our future expectation is that the value of PET will only augment owing to the implementation of FDG-PET in clinical guidelines, the increasing availability worldwide, and the development of new tracers and new hybrid imaging techniques

The role of angina pectoris in chronic pain after coronary artery bypass graft surgery.

Contains fulltext : 52784.pdf (publisher's version ) (Closed access)Visceral nociception readily sensitizes the central nervous system, causing referred somatic pain and hyperalgesia via somato-visceral convergence. Hyperalgesia in the perioperative period may increase vulnerability to subsequent development of chronic pain. The study aim is to investigate the role of angina pectoris, an ischemic visceral pain, in long-term pain after coronary artery bypass surgery (CABG). We sent questionnaires to 369 patients who underwent CABG surgery in 2003. Questions were asked about angina pectoris and other pain in the period before surgery, the first week postoperatively (= acute pain), and the period after 3 months after surgery (= chronic pain). We obtained results from 256 patients (response rate = 69%). The point prevalence of chronic pain after CABG was 27% after a mean follow-up of 16 months (SD +/- 3 months). Patients with chronic pain after CABG had more angina pectoris than those without chronic pain: Before surgery (P = .07), early on postoperatively (P = .004), and more than 3 months after surgery (P = .000004). We found cumulative prevalences of chronic pain after CABG at 3 months of 39%, and of 32% after 6 months. Other predictive factors for chronic pain after CABG were acute postoperative pain (P = .00002) and younger age (P = .002). Angina pectoris is associated with chronic pain after CABG surgery. Other predictive factors include acute postoperative pain and younger age. PERSPECTIVE: The influence of postoperative angina pectoris for chronic pain after CABG surgery has not been described in the literature to date. Visceral nociception may play an important role in the development of chronic pain after surgery and should be taken into account in future studies

[Ventricular assist device implantation as a bridge to cardiac transplantation in two adolescents with end-stage cardiomyopathy and heart failure as a result of anthracycline use]

Contains fulltext : 69207.pdf (publisher's version ) (Closed access)In a adolescent women aged 15 and 17 years respectively, severe heart failure developed within a few months of anthracycline chemotherapy given for osteosarcoma. In the guidelines of the European Society of Cardiology, malignancy with a remission duration of less than 5 years is an absolute contraindication to cardiac transplantation. Neither patient was eligible to receive a ventricular assist device (VAD) as a bridge to cardiac transplantation in the Netherlands, but they were accepted in Germany. One patient received a cardiac transplant 13 months later and at the last follow-up check she was in good health with a remission of 3 years. The other patient developed bone metastases 6 months after the VAD implantation. Cardiac transplantation was not a treatment option for her. Dose-dependent cardiotoxicity is a serious complication of the use of anthracyclines. In severe heart failure the prognosis is often worse than in adjuvantly treated malignancies like osteosarcoma. VAD may therefore be a valid option for patients with severe heart failure after anthracycline use for a malignancy. In cases of sustained remission VAD may be the bridge to transplantation
