RESUMEN

BACKGROUND: Temporary drug treatment cessation might alleviate toxicity without substantially compromising efficacy in patients with cancer. We aimed to determine if a tyrosine kinase inhibitor drug-free interval strategy was non-inferior to a conventional continuation strategy for first-line treatment of advanced clear cell renal cell carcinoma. METHODS: This open-label, non-inferiority, randomised, controlled, phase 2/3 trial was done at 60 hospital sites in the UK. Eligible patients (aged ≥18 years) had histologically confirmed clear cell renal cell carcinoma, inoperable loco-regional or metastatic disease, no previous systemic therapy for advanced disease, uni-dimensionally assessed Response Evaluation Criteria in Solid Tumours-defined measurable disease, and an Eastern Cooperative Oncology Group performance status of 0-1. Patients were randomly assigned (1:1) at baseline to a conventional continuation strategy or drug-free interval strategy using a central computer-generated minimisation programme incorporating a random element. Stratification factors were Memorial Sloan Kettering Cancer Center prognostic group risk factor, sex, trial site, age, disease status, tyrosine kinase inhibitor, and previous nephrectomy. All patients received standard dosing schedules of oral sunitinib (50 mg per day) or oral pazopanib (800 mg per day) for 24 weeks before moving into their randomly allocated group. Patients allocated to the drug-free interval strategy group then had a treatment break until disease progression, when treatment was re-instated. Patients in the conventional continuation strategy group continued treatment. Patients, treating clinicians, and the study team were aware of treatment allocation. The co-primary endpoints were overall survival and quality-adjusted life-years (QALYs); non-inferiority was shown if the lower limit of the two-sided 95% CI for the overall survival hazard ratio (HR) was 0·812 or higher and if the lower limit of the two-sided 95% CI of the marginal difference in mean QALYs was -0·156 or higher. The co-primary endpoints were assessed in the intention-to-treat (ITT) population, which included all randomly assigned patients, and the per-protocol population, which excluded patients in the ITT population with major protocol violations and who did not begin their randomisation allocation as per the protocol. Non-inferiority was to be concluded if it was met for both endpoints in both analysis populations. Safety was assessed in all participants who received a tyrosine kinase inhibitor. The trial was registered with ISRCTN, 06473203, and EudraCT, 2011-001098-16. FINDINGS: Between Jan 13, 2012, and Sept 12, 2017, 2197 patients were screened for eligibility, of whom 920 were randomly assigned to the conventional continuation strategy (n=461) or the drug-free interval strategy (n=459; 668 [73%] male and 251 [27%] female; 885 [96%] White and 23 [3%] non-White). The median follow-up time was 58 months (IQR 46-73 months) in the ITT population and 58 months (46-72) in the per-protocol population. 488 patients continued on the trial after week 24. For overall survival, non-inferiority was demonstrated in the ITT population only (adjusted HR 0·97 [95% CI 0·83 to 1·12] in the ITT population; 0·94 [0·80 to 1·09] in the per-protocol population). Non-inferiority was demonstrated for QALYs in the ITT population (n=919) and per-protocol (n=871) population (marginal effect difference 0·06 [95% CI -0·11 to 0·23] for the ITT population; 0·04 [-0·14 to 0·21] for the per-protocol population). The most common grade 3 or worse adverse events were hypertension (124 [26%] of 485 patients in the conventional continuation strategy group vs 127 [29%] of 431 patients in the drug-free interval strategy group); hepatotoxicity (55 [11%] vs 48 [11%]); and fatigue (39 [8%] vs 63 [15%]). 192 (21%) of 920 participants had a serious adverse reaction. 12 treatment-related deaths were reported (three patients in the conventional continuation strategy group; nine patients in the drug-free interval strategy group) due to vascular (n=3), cardiac (n=3), hepatobiliary (n=3), gastrointestinal (n=1), or nervous system (n=1) disorders, and from infections and infestations (n=1). INTERPRETATION: Overall, non-inferiority between groups could not be concluded. However, there seemed to be no clinically meaningful reduction in life expectancy between the drug-free interval strategy and conventional continuation strategy groups and treatment breaks might be a feasible and cost-effective option with lifestyle benefits for patients during tyrosine kinase inhibitor therapy in patients with renal cell carcinoma.

RESUMEN

OBJECTIVES: To report the NHS Digital (NHSD) data for patients diagnosed with kidney cancer (KC) in England. We explore the incidence, route to diagnosis (RTD), treatment, and survival patterns from 2013 to 2019. MATERIALS AND METHODS: Data was extracted from the Cancer Data NHSD portal for International Classification of Diseases, 10th edition coded KC; this included Cancer Registry data, Hospital Episode Statistics, and cancer waiting times data. RESULTS: Registrations included 66 696 individuals with KC. Incidence of new KC diagnoses increased (8998 in 2013, to 10 232 in 2019), but the age-standardised rates were stable (18.7-19.4/100 000 population). Almost half of patients (30 340 [45.5%]) were aged 0-70 years and the cohort were most frequently diagnosed with Stage 1-2 KC (n = 26 297 [39.4%]). Most patients were diagnosed through non-urgent general practitioner referrals (n = 16 814 [30.4%]), followed by 2-week-wait (n = 15 472 [28.0%]) and emergency routes (n = 11 796 [21.3%]), with older patients (aged ≥70 years), Stage 4 KCs, and patients with non-specified renal cell carcinoma being significantly more likely to present through the emergency route (all P < 0.001). Invasive treatment (surgery or ablation), radiotherapy, or systemic anti-cancer therapy use varied with disease stage, patient factors, and treatment network (Cancer Alliance). Survival outcomes differed by Stage, histological subtype, and social deprivation class (P < 0.001). Age-standardised mortality rates did not change over the study duration, although immunotherapy usage is likely not captured in this study timeline. CONCLUSION: The NHSD resource provides useful insight about the incidence, diagnostic pathways, treatment, and survival of patients with KC in England and a useful benchmark for the upcoming commissioned National Kidney Cancer Audit. The RTD data may be limited by incidental diagnoses, which could confound the high proportion of 'emergency' diagnoses. Importantly, survival outcomes remained relatively unchanged.

RESUMEN

BACKGROUND: Bone is the most frequent site of metastases from breast cancer (BC), but no biomarkers are yet available to predict skeletal dissemination. METHODS: We attempted to identify a gene signature correlated with bone metastasis (BM) onset in circulating tumour cells (CTCs), isolated by a DEPArray-based protocol from 40 metastatic BC patients and grouped according to metastasis sites, namely "BM" (bone-only), "ES" (extra-skeletal) or BM + ES (bone + extra-skeletal). RESULTS: A 134-gene panel was first validated through targeted RNA sequencing (RNAseq) on sub-clones of the MDA-MB-231 BC cell line with variable organotropism, which successfully shaped their clustering. The panel was then applied to CTC groups and, in particular, the "BM" vs "ES" CTC comparison revealed 31 differentially expressed genes, including MAF, CAPG, GIPC1 and IL1B, playing key prognostic roles in BC. CONCLUSION: Such evidence confirms that CTCs are suitable biological sources for organotropism investigation through targeted RNAseq and might deserve future applications in wide-scale prospective studies.

RESUMEN

AIMS: Explore the knowledge, experiences, preferences, and concerns related to fertility preservation as an option for building a biological family among women with cystic fibrosis. DESIGN: Convergent mixed methods study design. METHODS: We recruited women with cystic fibrosis of childbearing age in the United States through cystic fibrosis centres, snowball sampling, and social media. Participants completed an anonymous survey about fertility and fertility preservation (n = 50). We also conducted audio-recorded, semi-structured interviews with a subset of women to gain a better understanding of their perspectives (n = 20). We transcribed the interviews verbatim and analysed them using thematic analysis. RESULTS: For the quantitative arm, 78% of women indicated that they would like to have a child in the future; however, 74% reported never having had conversations about fertility preservation with their providers. For the qualitative arm, four major themes emerged: (1) Women with cystic fibrosis have inadequate knowledge about fertility and fertility preservation; (2) fertility is a low priority area for the cystic fibrosis care team; (3) women with cystic fibrosis recommend that the cystic fibrosis care team provide specific fertility resources; and (4) providers and literature lack information on fertility and cystic fibrosis. Integrated findings identified that while the majority of women with cystic fibrosis want to become mothers in the future, including post-lung transplantation, they have not received education on fertility preservation, and there is a general lack of knowledge on the topic of fertility in cystic fibrosis. CONCLUSION: Women with cystic fibrosis desire to have children but have little knowledge about fertility preservation, and cystic fibrosis providers do not initiate family planning discussions. IMPACT: Findings from the study support that additional education is needed for women with cystic fibrosis who are considering parenthood. Clinical care models should include early, regular, and thoughtful discussions about reproductive health issues, including fertility preservation.

RESUMEN

CONTEXT: Active symptom monitoring is a key component of the public health response to COVID-19, but these activities are resource-intensive. Digital tools can help reduce the burden of staff time required for active symptom monitoring by automating routine outreach activities. PROGRAM: Sara Alert is an open-source, Web-based automated symptom monitoring tool launched in April 2020 to support state, tribal, local, and territorial jurisdictions in their symptom monitoring efforts. IMPLEMENTATION: As of October 2021, a total of 23 public health jurisdictions in the United States had used Sara Alert to perform daily symptom monitoring for more than 6.1 million individuals. This analysis estimates staff time and cost saved in 3 jurisdictions that used Sara Alert as part of their COVID-19 response, across 2 use cases: monitoring of close contacts exposed to COVID-19 (Arkansas; Fairfax County, Virginia), and traveler monitoring (Puerto Rico). EVALUATION: A model-based approach was used to estimate the additional staff resources that would have been required to perform the active symptom monitoring automated by Sara Alert, if monitoring instead relied on traditional methods such as telephone outreach. Arkansas monitored 283 705 individuals over a 10-month study period, generating estimated savings of 61.9 to 100.6 full-time equivalent (FTE) staff, or $2 798 922 to $4 548 249. Fairfax County monitored 63 989 individuals over a 13-month study period, for an estimated savings of 24.8 to 41.4 FTEs, or $2 826 939 to $4 711 566. In Puerto Rico, where Sara Alert was used to monitor 2 631 306 travelers over the 11-month study period, estimated resource savings were 849 to 1698 FTEs, or $26 243 161 to $52 486 322. DISCUSSION: Automated symptom monitoring helped reduce the staff time required for active symptom monitoring activities. Jurisdictions reported that this efficiency supported a rapid and comprehensive COVID-19 response even when experiencing challenges with quickly scaling up their public health workforce.

RESUMEN

BACKGROUND: The National Institute for Health and Care Excellence (NICE) recommend that men on androgen deprivation therapy (ADT) for prostate cancer should receive supervised exercise to manage the side-effects of treatment. However, these recommendations are rarely implemented into practice. Community-based exercise professionals (CBEPs) represent an important target group to deliver the recommendations nationally, yet their standard training does not address the core competencies required to work with clinical populations, highlighting a need for further professional training. This paper describes the development of a training package to support CBEPs to deliver NICE recommendations. METHODS: Development of the intervention was guided by the Medical Research Council guidance for complex interventions and the Behaviour Change Wheel. In step one, target behaviours, together with their barriers and facilitators were identified from a literature review and focus groups with CBEPs (n = 22) and men on androgen deprivation therapy (n = 26). Focus group outputs were mapped onto the Theoretical Domains Framework (TDF) to identify theoretical constructs for change. In step two, behaviour change techniques and their mode of delivery were selected based on psychological theories and evidence to inform intervention content. In step three, the intervention was refined following delivery and subsequent feedback from intervention recipients and stakeholders. RESULTS: Six modifiable CBEPs target behaviours were identified to support the delivery of the NICE recommendations. Nine domains of the TDF were identified as key determinants of change, including: improving knowledge and skills and changing beliefs about consequences. To target the domains, we included 20 BCTs across 8 training modules and took a blended learning approach to accommodate different learning styles and preferences. Following test delivery to 11 CBEPs and feedback from 28 stakeholders, the training package was refined. CONCLUSION: Established intervention development approaches provided a structured and transparent guide to intervention development. A training package for CBEPs was developed and should increase trust amongst patients and health care professionals when implementing exercise into prostate cancer care. Furthermore, if proven effective, the development and approach taken may provide a blueprint for replication in other clinical populations where exercise has proven efficacy but is insufficiently implemented.

RESUMEN

BACKGROUND: Twice-weekly supervised aerobic and resistance exercise for 12 weeks reduces fatigue and improves quality of life in men on Androgen Deprivation Therapy for prostate cancer. Despite the National Institute for Health and Care Excellence (NICE) proposing this as standard of care, it does not routinely take place in practice. Healthcare professionals are in a prime position to deliver and integrate these recommendations. A change in the behaviour of clinical teams is therefore required. In this paper, we describe the development of a training package for healthcare professionals using theory and evidence to promote delivery of such recommendations as standard care. METHODS: The intervention development process was guided by the Medical Research Council guidance for complex interventions and the Behaviour Change Wheel. Target behaviours were identified from the literature and thirty-five prostate cancer care healthcare professionals (including oncologists, consultant urologists, clinical nurse specialists, physiotherapists, general practitioners and commissioners) were interviewed to understand influences on these behaviours. The Theoretical Domains Framework was used to identify theoretical constructs for change. Behaviour change techniques were selected based on theory and evidence and were translated into intervention content. The intervention was refined with the input of stakeholders including healthcare professionals, patients, and exercise professionals in the form of rehearsal deliveries, focus groups and a workshop. RESULTS: Seven modifiable healthcare professional target behaviours were identified to support the delivery of the NICE recommendations including identifying eligible patients suitable for exercise, recommending exercise, providing information, exercise referral, providing support and interpret and feedback on progress. Ten domains from the Theoretical Domain's Framework were identified as necessary for change, including improving knowledge and skills, addressing beliefs about consequences, and targeting social influences. These were targeted through twenty-two behaviour change techniques delivered in a half-day, interactive training package. Based on initial feedback from stakeholders, the intervention was refined in preparation for evaluation. CONCLUSIONS: We designed an intervention based on theory, evidence, and stakeholder feedback to promote and support the delivery of NICE recommendations. Future work will aim to test this training package in a multi-centre randomised trial. If proven effective, the development and training package will provide a template for replication in other clinical populations, where exercise has proven efficacy but is insufficiently implemented.

RESUMEN

Skeletal metastasis occurs in around 75% of advanced breast cancers, with the disease incurable once cancer cells disseminate to bone, but there remains an unmet need for biomarkers to identify patients at high risk of bone recurrence. This study aimed to identify such a biomarker and to assess its utility in predicting response to adjuvant zoledronic acid (zoledronate). We used quantitative proteomics (stable isotope labelling by amino acids in cell culture-mass spectrometry; SILAC-MS) to compare protein expression in a bone-homing variant (BM1) of the human breast cancer cell line MDA-MB-231 with parental non-bone-homing cells to identify novel biomarkers for risk of subsequent bone metastasis in early breast cancer. SILAC-MS showed that dedicator of cytokinesis protein 4 (DOCK4) was upregulated in bone-homing BM1 cells, confirmed by western blotting. BM1 cells also had enhanced invasive ability compared with parental cells, which could be reduced by DOCK4-shRNA. In a training tissue microarray (TMA) comprising 345 patients with early breast cancer, immunohistochemistry followed by Cox regression revealed that high DOCK4 expression correlated with histological grade (p = 0.004) but not oestrogen receptor status (p = 0.19) or lymph node involvement (p = 0.15). A clinical validation TMA used tissue samples and the clinical database from the large AZURE adjuvant study (n = 689). Adjusted Cox regression analyses showed that high DOCK4 expression in the control arm (no zoledronate) was significantly prognostic for first recurrence in bone (HR 2.13, 95%CI 1.06-4.30, p = 0.034). No corresponding association was found in patients who received zoledronate (HR 0.812, 95%CI 0.176-3.76, p = 0.790), suggesting that treatment with zoledronate may counteract the higher risk for bone relapse from high DOCK4-expressing tumours. High DOCK4 expression was not associated with metastasis to non-skeletal sites when these were assessed collectively. In conclusion, high DOCK4 in early breast cancer is significantly associated with aggressive disease and with future bone metastasis and is a potentially useful biomarker for subsequent bone metastasis risk.

RESUMEN

BACKGROUND: Cystic fibrosis (CF) is a chronic, genetic, incurable disease that affects primarily the respiratory and gastrointestinal systems. End-stage lung disease is the leading cause of death in people with CF, and lung transplant is required to preserve life. Anti-rejection medications are necessary post-transplant; however, these medications lower immune response and increase susceptibility to bacterial infections. Complications from infections post lung-transplant account for approximately 30% of CF-related deaths. Retropharyngeal abscess (RPA) is a rare deep neck infection that occurs most commonly in children. This is the case of a 45-year-old Caucasian male with CF who developed a retropharyngeal abscess post wisdom teeth extraction that seeded into hardware from a previous cervical disc fusion. CASE PRESENTATION: The patient presented to the emergency department with severe neck and shoulder pain, limited range of motion in his arm and neck, and dysphonia. He reported feeling pain for 10 days and suspected the pain was caused by a weightlifting injury. The patient reported low-grade fever 5 days prior, which responded to acetaminophen. He was afebrile upon admission and in no respiratory distress. Diagnostic labs revealed WBC 22,000/uL and CRP 211 mg/L. The CT scan showed a large abscess in the retropharyngeal space between C2-C7. The immediate concern was airway obstruction and need for possible intubation or tracheostomy. The patient was transferred to ENT service with neurosurgery and transplant consults. The RPA was drained and lavaged. The cervical hardware was discovered to be infected and was removed. The source of the RPA infection was determined to be from the patient's wisdom teeth extraction 6 months prior to RPA. The patient received 8 weeks of intravenous ceftriaxone for Streptococcus pneumoniae bacteremia and underwent revision of his cervical fusion 3 months after hardware removal. CONCLUSIONS: Clinicians should consider prophylactic antimicrobial therapy for immunocompromised patients when they are at increased risk for transient bacteremia such as following invasive procedures (e.g., tooth extraction). Prophylactic antimicrobial therapy could prevent potentially life-threatening infections such as RPA in immunocompromised patients.

RESUMEN

PURPOSE: In older cancer patients, treatment decision-making is often complex. A comprehensive geriatric assessment (CGA) is an established tool used in geriatric medicine to identify unmet need requiring intervention. This study aimed to assess whether using a CGA in older male cancer patients with incurable but manageable disease provides information that would alter a cancer clinician's intended management plan. Acceptability and feasibility were secondary aims. METHODS: Elderly men with incurable but manageable malignancies (advanced prostate cancer and multiple myeloma) who had previously received at least one line of treatment were recruited from hospital outpatient clinics. A CGA was undertaken. Additional parameters measuring pain, fatigue and disease-specific concerns were also recorded, at the recommendation of patient involvement groups. Results were made available to clinicians. Patient and clinician acceptability and changes in subsequent management were recorded. RESULTS: Forty-eight patients completed the study. The median ages were 70.8 years and 74 years for myeloma and prostate respectively. Most identified concerns are related to disease-specific concerns (93%), pain (91%), frailty (57%) and nutrition (52%). Results altered the clinician's oncological management plan in nine cases only. Patients found the format and content of CGA acceptable. CONCLUSIONS: Many unmet needs were identified in this population of elderly men with manageable but non curable cancer which led to supportive care referrals and interventions. The CGA, however, did not result in significant changes in clinical oncology treatment plans for the majority of patients. The application of the CGA and other assessments was viewed positively by participants and can feasibly be undertaken in the outpatient oncology setting.

RESUMEN

PURPOSE OF REVIEW: The improvement in prostate cancer survival over time, even in those with advanced disease, has led to an increasing recognition of the impact of prostate cancer and its treatment on bone health. Cancer treatment-induced bone loss (CTIBL) is a well-recognized entity but greater awareness of the risks associated with CTIBL and its treatment is required. RECENT FINDINGS: The principal culprit in causing CTIBL is hormonal ablation induced by prostate cancer treatment, including several new agents which have been developed in recent years which significantly improve survival, but may cause CTIBL. This review discusses the impact of prostate cancer and its treatment on bone health, including published evidence on the underlying pathophysiology, assessment of bone health, and strategies for prevention and treatment. It is important to recognize the potential cumulative impact of systemic prostate cancer treatments on bone health.

RESUMEN

BACKGROUND: This study aimed to explore the opinions of healthcare professionals regarding the management of men with advanced prostate cancer with particular emphasis on treatment timing and sequencing; treatment adverse-effects and exercise a supportive therapy. METHODS: Semi-structured interviews with a purposively selected group of healthcare professionals involved in prostate cancer care within the NHS, conducted over the phone or face to face. A total of 37 healthcare professionals participated in the interviews including urologists, clinical oncologists, medical oncologists, clinical nurse specialists, general practitioners, physiotherapists, exercise specialists, service managers, clinical commissioners and primary care physicians. RESULTS: The availability of newer treatments for advanced prostate cancer as well as results from the STAMPEDE and CHAARTED trials has resulted in new challenges for patients and HCPs. This includes the impact of an increased workload on oncologists, a potential lack of clinical continuity between urology and oncology and uncertainties regarding optimal selection, timing and sequencing of chemotherapy and second-line treatment. Fitness for treatment in advanced prostate cancer populations remains a significant barrier to accessing therapies for patients with a poor performance status. Among this, muscle wastage can significantly affect performance status and consequentially compromise cancer therapy. Exercise was regarded as a potential therapy to mitigate the adverse-effects of treatment including the prevention or reduction in muscle wastage. CONCLUSIONS: There is a lack of data guiding clinicians in this post STAMPEDE and CHAARTED era, work is needed to reassess and optimize the prostate cancer care pathway as it evolves. Exercise should be explored as a therapeutic option to mitigate the effects of long term ADT. Further study from a wider cohort of both prostate cancer care specialists and patients will aid in establishing a highly functioning pathway with optimal individualised care. TRIAL REGISTRATION: Sustained exercise TrAining for Men wIth prostate caNcer on Androgen deprivation: the STAMINA programme (RP-DG-1213-10,010).

RESUMEN

Considerable advances in oncology over recent decades have led to improved survival, while raising concerns about long-term consequences of anticancer treatments. In patients with breast or prostate malignancies, bone health is a major issue due to the high risk of bone metastases and the frequent prolonged use of hormone therapies that alter physiological bone turnover, leading to increased fracture risk. Thus, the onset of cancer treatment-induced bone loss (CTIBL) should be considered by clinicians and recent guidelines should be routinely applied to these patients. In particular, baseline and periodic follow-up evaluations of bone health parameters enable the identification of patients at high risk of osteoporosis and fractures, which can be prevented by the use of bone-targeting agents (BTAs), calcium and vitamin D supplementation and modifications of lifestyle. This review will focus upon the pathophysiology of breast and prostate cancer treatment-induced bone loss and the most recent evidence about effective preventive and therapeutic strategies.

RESUMEN

OBJECTIVE: To evaluate the cost-effectiveness of adding zoledronic acid or strontium-89 to standard docetaxel chemotherapy for patients with castrate-refractory prostate cancer (CRPC). PATIENTS AND METHODS: Data on resource use and quality of life for 707 patients collected prospectively in the TRAPEZE 2 × 2 factorial randomised trial (ISRCTN 12808747) were used to assess the cost-effectiveness of i) zoledronic acid versus no zoledronic acid (ZA vs. no ZA), and ii) strontium-89 versus no strontium-89 (Sr89 vs. no Sr89). Costs were estimated from the perspective of the National Health Service in the UK and included expenditures for trial treatments, concomitant medications, and use of related hospital and primary care services. Quality-adjusted life-years (QALYs) were calculated according to patients' responses to the generic EuroQol EQ-5D-3L instrument, which evaluates health status. Results are expressed as incremental cost-effectiveness ratios (ICERs) and cost-effectiveness acceptability curves. RESULTS: The per-patient cost for ZA was £12 667, £251 higher than the equivalent cost in the no ZA group. Patients in the ZA group had on average 0.03 QALYs more than their counterparts in no ZA group. The ICER for this comparison was £8 005. Sr89 was associated with a cost of £13 230, £1365 higher than no Sr89, and a gain of 0.08 QALYs compared to no Sr89. The ICER for Sr89 was £16 884. The probabilities of ZA and Sr89 being cost-effective were 0.64 and 0.60, respectively. CONCLUSIONS: The addition of bone-targeting treatments to standard chemotherapy led to a small improvement in QALYs for a modest increase in cost (or cost-savings). ZA and Sr89 resulted in ICERs below conventional willingness-to-pay per QALY thresholds, suggesting that their addition to chemotherapy may represent a cost-effective use of resources.

RESUMEN

The worst complication of cancer is represented by its spread to distant sites. In particular, bone provides a fertile soil for several cancer types, especially those derived from breast, prostate and lung tumours. Despite the progress in diagnostic and therapeutic strategies, bone metastases (BM) still impact on quality of life and overall survival, making it necessary to identify the "high-risk" patients at an earlier stage. Since BM affect physiological bone turnover, measurement of bone turnover markers (BTM) has been widely investigated for diagnostic and prognostic purposes, as well as to support the development of anti-cancer drugs. Furthermore, biomarkers are still under intensive investigation for their potential BM predictive role. The review summarises the current knowledge on BM development and the most recent advances in biomarker research, focusing on breast, prostate and lung malignancies.

RESUMEN

PURPOSE: Bone metastases secondary to solid tumors increase the risk of skeletal-related events (SREs), including the occurrence of pathological fracture (PF), radiation to bone (RB), surgery to bone (SB), and spinal cord compression (SCC). The aim of this study was to evaluate the impact of SREs on patients' pain, analgesic use, and pain interference with daily functioning. METHODS: Data were combined from patients with solid tumors and bone metastases who received denosumab or zoledronic acid across three identically designed phase 3 trials (N = 5543). Pain severity (worst pain) and pain interference were assessed using the Brief Pain Inventory at baseline and each monthly visit. Analgesic use was quantified using the Analgesic Quantification Algorithm. RESULTS: The proportion of patients with moderate/severe pain and strong opioid use generally increased in the 6 months preceding an SRE and remained elevated, while they remained relatively consistent over time in patients without an SRE. Regression analysis indicated that all SRE types were significantly associated with an increased risk of progression to moderate/severe pain and strong opioid use. PF, RB, and SCC were associated with significantly greater risk of pain interference overall. Results were similar for pain interference with emotional well-being. All SRE types were associated with significantly greater risk of pain interference with physical function. CONCLUSIONS: SREs are associated with increased pain and analgesic use in patients with bone metastases. Treatments that prevent SREs may decrease pain and the need for opioid analgesics and reduce the impact of pain on daily functioning.

RESUMEN

PURPOSE: Zoledronic acid (ZA) or denosumab treatment reduces skeletal-related events; however, the safety of prolonged therapy has not been adequately studied. Here, we describe safety results of extended denosumab therapy in patients with bone metastases from the open-label extension phase of two phase 3 trials. METHODS: Patients with metastatic breast or prostate cancer received subcutaneous denosumab 120 mg Q4W or intravenous ZA 4 mg Q4W in a double-blinded fashion. Denosumab demonstrated superior efficacy in the blinded treatment phase; thus, patients were offered open-label denosumab for up to an additional 2 years. RESULTS: Cumulative median (Q1, Q3) denosumab exposure was 19.1 (9.2, 32.2) months in the breast cancer trial (n = 1019) and 12.0 (5.6, 21.3) months in the prostate cancer trial (n = 942); 295 patients received denosumab for >3 years. No new safety signals were identified during the open-label phase, or among patients who switched from ZA to denosumab. During the blinded treatment phase, exposure-adjusted subject incidences of osteonecrosis of the jaw (ONJ) were 49 (1.9%) and 31 (1.2%) in the denosumab and ZA groups, respectively. In total, 32 (6.9%) and 25 (5.5 %) new cases of ONJ (not adjusted for exposure) were reported for patients continuing and switching to denosumab, respectively. The incidences of hypocalcemia were 4.3 and 3.1%, in patients continuing and switching to denosumab, respectively. CONCLUSION: These results describe the safety profile of denosumab after long-term exposure, or after switching to denosumab from ZA. No new safety signals were identified. Hypocalcemia rates were similar in the blinded treatment and open-label phases. ONJ rates increased with increasing exposure to antiresorptives, consistent with previous reports.

RESUMEN

It has been suggested that offering perioperative nursing courses will increase the number of nurses and new graduates who enter the perioperative area. There is little research to support that students' career choices are influenced by immersion in perioperative content. The purpose of this qualitative study was to describe student perceptions of perioperative nursing as a career option following completion of an elective in perioperative nursing. Two focus groups were held involving students (N=19) who completed the course. One hour sessions were audio taped as students described their perceptions about perioperative nursing. Tapes were transcribed verbatim and analysed for themes. Four themes were identified: 1) opening their eyes: career advantages, 2) being captive: career disadvantages, 3) paradox unrecognized, and 4) I'll be a better nurse. Although students were not persuaded to alter their primary employment intentions, they acknowledged the possibility of a future career in the perioperative area.

RESUMEN

BACKGROUND: Prostate Cancer (PCa) is the commonest cancer in the UK. Androgen deprivation therapy (ADT) is a mainstay of treatment. It increases fragility fractures causing a huge burden to patients and the NHS. As men live longer with PCa, many require prolonged ADT. Reducing fracture risks and improving cancer survivorship is becoming increasingly important. Primary care plays an important role. AIM: To evaluate how fracture risk of PCa patients taking ADT (PCa-ADT) was assessed and managed in primary care. METHOD: A retrospective multi-practice database study. PCa patients were identified using SNOMED codes from five sociodemographically diverse practices (registered population 49 400). Data were extracted by hand-searching records, including hospital letters, and included: demographics; a 10-year fragility fracture score (FRAX); NOGG intervention threshold; DEXA requests; and use of bisphosphonates. RESULTS: Of the 261 PCa patients identified, 6% were Black African/Caribbean and 89% White British. Half had been prescribed ADT, 28% being current users. No fracture risk assessment was documented for any patients. ADT current users had significantly increased FRAX scores for both major osteoporotic fractures (MOF) (9.61%±1.12%) and hip fracture (HF) (5.30%±1.02%) compared with PCa patients without ADT (7.08%±0.57% [MOF] and 3.06%±0.46% [HF], P<0.001). For ADT current users, 39% showed intermediate fracture risk (NOGG amber), warranting a DEXA scan, with only 30% performed. Patients in more affluent areas received more DEXA scans and bisphosphonate treatment. CONCLUSION: Osteoporosis is underdiagnosed and undertreated in men with PCa-ADT, especially in those with deprived backgrounds. There is an unmet need to manage the fracture prevention in this population.
