Antibody-drug conjugates in lung and breast cancer: current evidence and future directions-a position statement from the ETOP IBCSG Partners Foundation

Following the approval of the first antibody-drug conjugates (ADCs) in the early 2000s, development has increased dramatically, with 14 ADCs now approved and >100 in clinical development. In lung cancer, trastuzumab deruxtecan (T-DXd) is approved in human epidermal growth factor receptor 2 (HER2)-mutated, unresectable or metastatic non-small-cell lung cancer, with ADCs targeting HER3 (patritumab deruxtecan), trophoblast cell-surface antigen 2 [datopotamab deruxtecan and sacituzumab govitecan (SG)] and mesenchymal-epithelial transition factor (telisotuzumab vedotin) in late-stage clinical development. In breast cancer, several agents are already approved and widely used, including trastuzumab emtansine, T-DXd and SG, and multiple late-stage trials are ongoing. Thus, in the coming years, we are likely to see significant changes to treatment algorithms. As the number of available ADCs increases, biomarkers (of response and resistance) to better select patients are urgently needed. Biopsy sample collection at the time of treatment selection and incorporation of translational research into clinical trial designs are therefore critical. Biopsy samples taken peri- and post-ADC treatment combined with functional genomics screens could provide insights into response/resistance mechanisms as well as the impact of ADCs on tumour biology and the tumour microenvironment, which could improve understanding of the mechanisms underlying these complex molecules. Many ADCs are undergoing evaluation as combination therapy, but a high bar should be set to progress clinical evaluation of any ADC-based combination, particularly considering the high cost and potential toxicity implications. Efforts to optimise ADC dosing/duration, sequencing and the potential for ADC rechallenge are also important, especially considering sustainability aspects. The ETOP IBCSG Partners Foundation are driving strong collaborations in this field and promoting the generation/sharing of databases, repositories and registries to enable greater access to data. This will allow the most important research questions to be identified and prioritised, which will ultimately accelerate progress and help to improve patient outcomes.

Physiotherapist- and patient-reported barriers to guideline implementation of active physiotherapeutic management of low back pain: A theory-informed qualitative study

BACKGROUND AND OBJECTIVE

Adoption of low back pain (LBP) guidelines in physiotherapeutic management is a well-documented problem. Thereby, an in-depth understanding of the barriers to implement an active approach for both patients and physiotherapists is needed.

DESIGN

Semi-structured interviews were conducted with physiotherapists and patients with non-specific LBP. Interviews, guided by the Theoretical Domains Framework (TDF), were analyzed using the Qualitative Analysis Guide of Leuven.

RESULTS

A total of 20 participants were interviewed, including ten physiotherapists and ten patients. Our findings reveal that patients and physiotherapists face each 23 barriers spanning 14 TDF domains. The TDF domain "social influences" revealed the most barriers, followed by "beliefs about consequences" and "environmental context" for patients and physiotherapists, respectively. Five barriers did overlap between both groups (lack of guideline awareness, incorrect exercise performance, interdisciplinary communication gaps, time constraints and challenges in patient compliance).

CONCLUSIONS

Barriers to LBP guideline recommended physiotherapeutic practices span all 14 TDF domains. Consequently, future implementation interventions need to address multiple TDF domains for effective LBP guideline implementation.

Towards a standardized framework for AI-assisted, image-based monitoring of nocturnal insects

Automated sensors have potential to standardize and expand the monitoring of insects across the globe. As one of the most scalable and fastest developing sensor technologies, we describe a framework for automated, image-based monitoring of nocturnal insects-from sensor development and field deployment to workflows for data processing and publishing. Sensors comprise a light to attract insects, a camera for collecting images and a computer for scheduling, data storage and processing. Metadata is important to describe sampling schedules that balance the capture of relevant ecological information against power and data storage limitations. Large data volumes of images from automated systems necessitate scalable and effective data processing. We describe computer vision approaches for the detection, tracking and classification of insects, including models built from existing aggregations of labelled insect images. Data from automated camera systems necessitate approaches that account for inherent biases. We advocate models that explicitly correct for bias in species occurrence or abundance estimates resulting from the imperfect detection of species or individuals present during sampling occasions. We propose ten priorities towards a step-change in automated monitoring of nocturnal insects, a vital task in the face of rapid biodiversity loss from global threats. This article is part of the theme issue 'Towards a toolkit for global insect biodiversity monitoring'.

A needs assessment for enhancing workplace-based assessment: a grounded theory study

OBJECTIVES

Workplace-based assessment (WBA) has been vigorously criticized for not fulfilling its educational purpose by medical educators. A comprehensive exploration of stakeholders' needs regarding WBA is essential to optimize its implementation in clinical practice.

METHOD

Three homogeneous focus groups were conducted with three groups of stakeholders: General Practitioner (GP) trainees, GP trainers, and GP tutors. Due to COVID-19 measures, we opted for an online asynchronous form to enable participation. An constructivist grounded theory approach was used to employ this study and allow the identification of stakeholders' needs for using WBA.

RESULTS

Three core needs for WBA were identified in the analysis. Within GP Training, stakeholders found WBA essential, primarily, for establishing learning goals, secondarily, for assessment purposes, and, lastly, for providing or receiving feedback.

CONCLUSION

All stakeholders perceive WBA as valuable when it fosters learning. The identified needs were notably influenced by agency, trust, availability, and mutual understanding. These were facilitating factors influencing needs for WBA. Embracing these insights can significantly illuminate the landscape of workplace learning culture for clinical educators and guide a successful implementation of WBA.

Real-world outcomes with durvalumab after chemoradiotherapy in patients with unresectable stage III NSCLC: interim analysis of overall survival from PACIFIC-R

BACKGROUND

Based on the findings of the PACIFIC trial, consolidation durvalumab following platinum-based chemoradiotherapy (CRT) is a global standard of care for patients with unresectable, stage III non-small-cell lung cancer (NSCLC). An earlier analysis from the ongoing PACIFIC-R study (NCT03798535) demonstrated the effectiveness of this regimen in terms of progression-free survival (PFS). Here, we report the first planned overall survival (OS) analysis.

PATIENTS AND METHODS

PACIFIC-R is an observational/non-interventional, retrospective study of patients with unresectable, stage III NSCLC who started durvalumab (10 mg/kg intravenously every 2 weeks) within an AstraZeneca-initiated early access program between September 2017 and December 2018. Primary endpoints are OS and investigator-assessed PFS, estimated using the Kaplan-Meier method.

RESULTS

By 30 November 2021, the full analysis set included 1154 participants from 10 countries (median follow-up in censored patients: 38.7 months). Median OS was not reached, and the 3-year OS rate was 63.2% (95% confidence interval 60.3% to 65.9%). Three-year OS rates were numerically higher among patients with programmed death-ligand 1 (PD-L1) expression on ≥1% versus <1% of tumor cells (TCs; 67.0% versus 54.4%) and patients who received concurrent CRT (cCRT) versus sequential CRT (sCRT) (64.8% versus 57.9%).

CONCLUSIONS

PACIFIC-R data continue to provide evidence for the effectiveness of consolidation durvalumab after CRT in a large, diverse, real-world population. Better outcomes were observed among patients with PD-L1 TCs ≥1% and patients who received cCRT. Nevertheless, encouraging outcomes were still observed among patients with TCs <1% and patients who received sCRT, supporting use of consolidation durvalumab in a broad population of patients with unresectable, stage III NSCLC.

Co-designing Entrustable Professional Activities in General Practitioner's training: a participatory research study

BACKGROUND

In medical education, Entrustable Professional Activities (EPAs) have been gaining momentum for the last decade. Such novel educational interventions necessitate accommodating competing needs, those of curriculum designers, and those of users in practice, in order to be successfully implemented.

METHODS

We employed a participatory research design, engaging diverse stakeholders in designing an EPA framework. This iterative approach allowed for continuous refinement, shaping a comprehensive blueprint comprising 60 EPAs. Our approach involved two iterative cycles. In the first cycle, we utilized a modified-Delphi methodology with clinical competence committee (CCC) members, asking them whether each EPA should be included. In the second cycle, we used semi-structured interviews with General Practitioner (GP) trainers and trainees to explore their perceptions about the framework and refine it accordingly.

RESULTS

During the first cycle, 14 CCC members agreed that all the 60 EPAs should be included in the framework. Regarding the formulation of each EPAs, 20 comments were given and 16 adaptations were made to enhance clarity. In the second cycle, the semi-structured interviews with trainers and trainees echoed the same findings, emphasizing the need of the EPA framework for improving workplace-based assessment, and its relevance to real-world clinical scenarios. However, trainees and trainers expressed concerns regarding implementation challenges, such as the large number of EPAs to be assessed, and perception of EPAs as potentially high-stakes.

CONCLUSION

Accommodating competing stakeholders' needs during the design process can significantly enhance the EPA implementation. Recognizing users as experts in their own experiences empowers them, enabling a priori identification of implementation barriers and potential pitfalls. By embracing a collaborative approach, wherein diverse stakeholders contribute their unique viewpoints, we can only create effective educational interventions to complex assessment challenges.

Aligning organisational priorities and implementation science for cancer research

BACKGROUND

The challenge of implementing evidence into routine clinical practice is well recognised and implementation science offers theories, models and frameworks to promote investigation into delivery of evidence-based care. Embedding implementation researchers into health systems is a novel approach to ensuring research is situated in day-to-day practice dilemmas. To optimise the value of embedded implementation researchers and resources, the aim of this study was to investigate stakeholders' views on opportunities for implementation science research in a cancer setting that holds potential to impact on care. The research objectives were to: 1) Establish stakeholder and theory informed organisation-level implementation science priorities and 2) Identify and prioritise a test case pilot implementation research project.

METHODS

We undertook a qualitative study using semi-structured interviews. Participants held either a formal leadership role, were research active or a consumer advocate and affiliated with either a specialist cancer hospital or a cancer alliance of ten hospitals. Interview data were summarised and shared with participants prior to undertaking both thematic analysis, to identify priority areas for implementation research, and content analysis, to identify potential pilot implementation research projects. The selected pilot Implementation research project was prioritised using a synthesis of an organisational and implementation prioritisation framework - the organisational priority setting framework and APEASE framework.

RESULTS

Thirty-one people participated between August 2022 and February 2023. Four themes were identified: 1) Integration of services to address organisational priorities e.g., tackling fragmented services; 2) Application of digital health interventions e.g., identifying the potential benefits of digital health interventions; 3) Identification of potential for implementation research, including deimplementation i.e., discontinuing ineffective or low value care and; 4) Focusing on direct patient engagement e.g., wider consumer awareness of the challenges in delivering cancer care. Six potential pilot implementation research projects were identified and the EMBED project, to support clinicians to refer appropriate patients with cancer for genetic testing, was selected using the synthesised prioritisation framework.

CONCLUSIONS

Using a theory informed and structured approach the alignment between strategic organisational priorities and implementation research priorities can be identified. As a result, the implementation research focus can be placed on activities with the highest potential impact.

Assessing infection prevention and control programs in residential aged care in Australia: A multi-methods cross-sectional study

AIM

To assess infection prevention and control programs in residential aged care facilities.

METHODS

A cross-sectional survey and structured interviews from 10 residential aged care facilities in Victoria, Australia, were used. Infection prevention and control nurse leads from each facility completed a purpose-built survey based on best practice infection prevention control program core components, including staff training, policies and procedures, governance, and surveillance. Follow-up interviews with residential aged care staff, residents and family visitors were carried out to elaborate and verify survey data.

RESULTS

Surveys from all 10 facilities were received and 75 interviews carried out. All facilities had an infection prevention and control lead nurse who had undergone additional training, and 60% of facilities had an infection prevention and control lead position description. All facilities had a committee to oversee their infection prevention and control program, and all had policies and procedures for standard and transmission-based precautions. One facility did not have a policy on healthcare-associated infection surveillance, and two facilities did not have an antimicrobial stewardship policy. All facilities provided staff training in hand hygiene and personal protective equipment use, but not all routinely assessed competency in these.

CONCLUSIONS

The residential aged care facilities' infection prevention and control programs were generally in a strong position, although there were some areas that require improvement. Further assessment of the quality of infection prevention and control program components, such as content of education and training, and policies and procedures, and ongoing evaluation of programs is recommended.

SAPPHIRE: phase III study of sitravatinib plus nivolumab versus docetaxel in advanced nonsquamous non-small-cell lung cancer

BACKGROUND

Checkpoint inhibitor (CPI) therapy revolutionized treatment for advanced non-small-cell lung cancer (NSCLC); however, most patients progress due to primary or acquired resistance. Sitravatinib is a receptor tyrosine kinase inhibitor that can shift the immunosuppressive tumor microenvironment toward an immunostimulatory state. Combining sitravatinib with nivolumab (sitra + nivo) may potentially overcome initial CPI resistance.

PATIENTS AND METHODS

In the phase III SAPPHIRE study, patients with advanced non-oncogenic driven, nonsquamous NSCLC who initially benefited from (≥4 months on CPI without progression) and subsequently experienced disease progression on or after CPI combined with or following platinum-based chemotherapy were randomized 1 : 1 to sitra (100 mg once daily administered orally) + nivo (240 mg every 2 weeks or 480 mg every 4 weeks administered intravenously) or docetaxel (75 mg/m2 every 3 weeks administered intravenously). The primary endpoint was overall survival (OS). The secondary endpoints included progression-free survival (PFS), objective response rate (ORR), clinical benefit rate (CBR), duration of response (DOR; all assessed by blinded independent central review), and safety.

RESULTS

A total of 577 patients included randomized: sitra + nivo, n = 284; docetaxel, n = 293 (median follow-up, 17.1 months). Sitra + nivo did not significantly improve OS versus docetaxel [median, 12.2 versus 10.6 months; hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.70-1.05; P = 0.144]. The median PFS was 4.4 versus 5.4 months, respectively (HR 1.08, 95% CI 0.89-1.32; P = 0.452). The ORR was 15.6% for sitra + nivo and 17.2% for docetaxel (P = 0.597); CBR was 75.5% and 64.5%, respectively (P = 0.004); median DOR was 7.4 versus 7.1 months, respectively (P = 0.924). Grade ≥3 treatment-related adverse events were observed in 53.0% versus 66.7% of patients receiving sitra + nivo versus docetaxel, respectively.

CONCLUSIONS

Although median OS was numerically longer with sitra + nivo, the primary endpoint was not met in patients with previously treated advanced nonsquamous NSCLC. The safety profiles demonstrated were consistent with previous reports.

[Resilience against IT attacks in hospitals : Results from an exercise in a German university hospital]

BACKGROUND

According to the legal definition healthcare systems and their components (e.g., hospitals) are part of the critical infrastructure of modern industrial nations. During the last few years hospitals increasingly became targets of cyber attacks causing severe impairment of their operability for weeks or even months. According to the German federal strategy for protection of critical infrastructures (KRITIS strategy), hospitals are obligated to take precautions against potential cyber attacks or other IT incidents.

OBJECTIVE

This article describes the process of planning, execution and results of an advanced table-top exercise which took place in a university hospital in Germany and simulated the first 3 days after a cyber attack causing a total failure of highly critical IT systems.

MATERIAL AND METHODS

During a first stage lasting about 8 months IT-dependent processes within the clinical routine were identified and analyzed. Then paper-based and off-line back-up processes and workarounds were developed and department-specific emergency plans were defined. Finally, selected central facilities such as pharmacy, laboratory, radiology, IT and the hospitals crisis management team took part in the actual disaster exercise. Afterwards the participants were asked to evaluate the exercise and the hospitals cyber security using a questionnaire. On this basis the authors visualized the hospital's resilience against cyber incidents and defined short-term, medium-term and long-term needs for action.

RESULTS

Of the participants 85% assessed the exercise as beneficial, 97% indicated that they received adequate support during the preparations and 75% had received sufficient information; however, only 34% had the opinion that the hospital's and their own preparedness against critical IT failures were sufficient. Before the exercise took place, IT-specific emergency plans were present only in 1.7% of the hospital facilities but after the exercise in 86.7% of the clinical and technical departments. The highest resilience against cyber attacks was not surprisingly reported by facilities that still work routinely with paper-based or off-line processes, the IT department showed the lowest resilience as it would come to a complete shutdown in cases of a total IT failure.

CONCLUSION

The authors concluded that the planning phase is the most important stage of developing the whole exercise, giving the best opportunity for working out fallback levels and workarounds and through this strengthen the hospitals resilience against cyber attacks and comparable incidents. A meticulous preparedness can minimize the severe effects a total IT failure can cause on patient care, staff and the hospital as a whole.

Venous 3D Phase Contrast Magnetic Resonance Angiography Increases Diagnostic Certainty in Children with Ventriculoperitoneal Shunt and Suspected Shunt Failure

BACKGROUND

Clinical symptoms in children with suspected malfunction of ventriculoperitoneal shunt may not be specific and difficult to interpret. The presence or absence of ventricular enlargement on magnetic resonance imaging (MRI) does not reliably predict raised intracranial pressure (ICP) in these patients. Therefore, the aim was to investigate the diagnostic utility of 3D venous phase-contrast MR angiography (vPCA) in these patients.

MATERIALS

The MR studies of two groups of patients at two different examination dates were retrospectively analyzed; one group without clinical symptoms on both examinations and one with symptoms of shunt dysfunction on one examination receiving surgery. Both MRI examinations had to have been performed including axial T2 weighted (T2-w) images and 3D vPCA. Two (neuro)radiologists evaluated T2-w images alone and in combination with 3D vPCA in terms of suspected elevated ICP. Interrater reliability, sensitivity and specificity were assessed.

RESULTS

Compression of venous sinuses was seen significantly more often in patients with shunt failure (p = 0.00003). Consequently, evaluation of 3D vPCA and T2-w images increases sensitivity to 0.92/1.0 compared to T2-w images alone with 0.69/0.77, the interrater agreement for the diagnosis of shunt failure rises from κ = 0.71 to κ = 0.837. Concerning imaging markers, three groups could be identified in children with shunt failure.

CONCLUSION

In accordance with the literature, the results show that ventricular morphology alone is an unreliable marker for elevated ICP in children with shunt malfunction. The findings confirmed 3D vPCA as a valuable supplemental diagnostic tool improving diagnostic certainty for children with unchanged ventricular size in cases of shunt failure.

Reducing long-term use of benzodiazepine receptor agonists: In-depth interview study with primary care stakeholders

AIMS

To increase our understanding of which factors contribute to long-term benzodiazepine receptor agonist (BZRA) use for insomnia in primary care, from a patients', general practitioners' (GP) and pharmacists' perspective.

DESIGN

Qualitative research following a grounded theory approach.

SETTING

Primary care in Belgium.

PARTICIPANTS

Twenty-four participants were interviewed, including nine patients, six GPs and nine pharmacists.

MEASUREMENTS

In-depth, semistructured interviews with iterative cycles of data collection and analysis. Transcripts were analysed using the framework method. Thematic findings were interpreted in the context of the Theoretical Domains Framework.

FINDINGS

A reflexive relation was identified between views about hypnotic use at the level of society, healthcare and patients. Behaviour change appeared to depend strongly on context and social influence, including a need for supporting relationships by all stakeholders. Six key messages captured factors that contribute to long-term BZRA use for insomnia in primary care: societal beliefs as a game changer, the opportunity of nonpharmacological treatment, collaborative primary care, patient-centred goals, informed consent and self-management.

CONCLUSIONS

Long-term BZRA use for insomnia is a complex and multifaceted public health problem that is not adequately addressed in primary care at this time. Although primary care professionals in this study found discontinuation of long-term BZRA use relevant to the patient's health, many organisational and personal barriers were reported. Moreover, the current social and healthcare context is not empowering patients and professionals to reduce long-term BZRA use for insomnia. Specifically, for primary care, all stakeholders reported the need for a nonmedicalised relationship between the patient and GP to lower prescribing rates.

PATIENT OR PUBLIC CONTRIBUTION

The Flemish Patient Platform, a patient representative organisation, assisted with recruitment by launching a call for participants in their newsletter and volunteered to disseminate the results. The call for recruitment was also published online in social media groups regarding insomnia and via posters in public pharmacies. Patients or public were not involved in designing or conducting the interview study.

ESMO study on the availability and accessibility of biomolecular technologies in oncology in Europe

BACKGROUND

Access to biomolecular technologies has become an essential requirement to ensure optimal and timely treatment of patients with cancer. This study sought to provide a comprehensive overview of the availability and accessibility of biomolecular technologies to patients, the status of their use and prescription, barriers to access, and potential economic issues related to cost and reimbursement.

MATERIALS AND METHODS

A total of 201 field reporters from 48 European countries submitted data through an electronic survey tool between July and December 2021. The survey methodology mirrored that from previous ESMO studies addressing the availability and accessibility of antineoplastic medicines, in Europe and worldwide. The preliminary data were posted on the ESMO website for open peer-review, and amendments were incorporated into the final report.

RESULTS

Overall, basic single-gene techniques are widely available, whereas access to advanced biomolecular technologies, including large next-generation sequencing panels and complete genomic profiles, is highly heterogeneous. In most countries, advanced biomolecular technologies remain largely inaccessible in clinical practice, are limited to clinical trials or basic research, and associated with progressively increasing cost as the technique becomes more advanced. Differences also exist regarding national sequencing initiatives or molecular tumour boards. The most important barriers to multiple versus single-gene sequencing techniques are the reimbursement of the test (59% versus 24%), and the availability of a suitable medicine, either through reimbursement of treatment (48% versus 30%), off-label treatment (52% versus 35%), or clinical trial enrolment (53% versus 39%).

CONCLUSIONS

Cost and availability of both treatment and test are the two main factors limiting patients' access to advanced biomolecular technologies and as a consequence to innovative anticancer strategies. In the era of precision medicine, tackling the accessibility to biomolecular technologies is a key step to reduce inequalities to transformative cancer care.

Communities of practice in residential aged care: A rapid review

BACKGROUND

Communities of practice (CoPs) have the potential to help address the residential aged care system's need for continuing education and quality improvement. CoPs have been used in healthcare to improve clinical practice; however, little is known about their application to the unique residential aged care context.

OBJECTIVES

This rapid review of CoPs for residential aged care was conducted to summarise the features of CoPs, how they are developed and maintained, and assess their effectiveness.

METHODS

MEDLINE and CINAHL databases were searched for studies published from January 1991 to November 2022 about CoPs in residential aged care. Data were extracted regarding the CoPs' three key features of 'domain', 'community' and 'practice' as described by Wenger and colleagues. Kirkpatrick's four levels of evaluation (members' reactions, learning, behaviour and results) was used to examine studies on the effectiveness of CoPs. The Mixed Methods Appraisal Tool was used for quality appraisal.

RESULTS

Nineteen articles reported on 13 residential aged care CoPs. Most CoPs aimed to improve care quality (n = 9, 69%) while others aimed to educate members (n = 3, 23%). Membership was often multidisciplinary (n = 8, 62%), and interactions were in-person (n = 6, 46%), online (n = 3, 23%) or both (n = 4, 31%). Some CoPs were developed with the aid of a planning group (n = 4, 31%) or as part of a larger collaborative (n = 4, 31%), and were maintained using a facilitator (n = 7, 54%) or adapted to member feedback (n = 2, 15%). Thirteen (81%) studies evaluated members' reactions, and three (24%) studies assessed members' behaviour. The heterogeneity of studies and levels of reporting made it difficult to synthesise findings.

CONCLUSIONS

This review revealed the variation in why, and how, CoPs have been used in residential aged care, which is consistent with previous reviews of CoPs in healthcare. While these findings can inform the development of CoPs in this context, further research is needed to understand how CoPs, including the membership makeup, delivery mode, facilitator type and frequency of meetings, impact quality of care.

Pathologist-initiated reflex testing for biomarkers in non-small-cell lung cancer: expert consensus on the rationale and considerations for implementation

Biomarker tests in lung cancer have been traditionally ordered by the treating oncologist upon confirmation of an appropriate pathological diagnosis. The delay this introduces prolongs yet further what is already a complex, multi-stage, pre-treatment pathway and delays the start of first-line systemic treatment, which is crucially informed by the results of such analysis. Reflex testing, in which the responsibility for testing for an agreed range of biomarkers lies with the pathologist, has been shown to standardise and expedite the process. Twelve experts discussed the rationale and considerations for implementing reflex testing as standard clinical practice.

Efficacy and safety of nivolumab for patients with pre-treated type B3 thymoma and thymic carcinoma: results from the EORTC-ETOP NIVOTHYM phase II trial

BACKGROUND

Thymic malignancies are rare intrathoracic tumors, which may be aggressive and difficult to treat. They represent a therapeutic challenge in the advanced/metastatic setting, with limited treatment options after the failure of first-line platinum-based chemotherapy. They are frequently associated with autoimmune disorders that also impact oncological management.

MATERIALS AND METHODS

NIVOTHYM is an international, multicenter, phase II, two-cohort, single-arm trial evaluating the activity and safety of nivolumab [240 mg intravenously (i.v.) q2 weeks] alone or with ipilimumab (1 mg /kg i.v. q6 weeks) in patients with advanced/relapsed type B3 thymoma or thymic carcinoma, after exposure to platinum-based chemotherapy. The primary endpoint is progression-free survival rate at 6 months (PFSR-6) based on RECIST 1.1 as per independent radiological review.

RESULTS

From April 2018 to February 2020, 55 patients were enrolled in 15 centers from 5 countries. Ten patients (18%) had type B3 thymoma and 43 (78%) had thymic carcinoma. The majority were male (64%), and the median age was 58 years. Among the 49 eligible patients who started treatment, PFSR-6 by central review was 35% [95% confidence interval (CI) 22% to 50%]. The overall response rate and disease control rate were 12% (95% CI 5% to 25%) and 63% (95% CI 48% to 77%), respectively. Using the Kaplan-Meier method, median progression-free survival and overall survival by local assessment were 6.0 (95% CI 3.1-10.4) months and 21.3 (95% CI 11.6-not estimable) months, respectively. In the safety population of 54 patients, adverse events (AEs) of grade 1/2 were observed in 22 (41%) patients and grade 3/4 in 31 (57%) patients. Treatment-related AEs of grade 4 included one case of neutropenia, one case of immune-mediated transaminitis, and two cases of myocarditis.

CONCLUSIONS

Nivolumab monotherapy demonstrated an acceptable safety profile and objective activity, although it has been insufficient to meet its primary objective. The second cohort of NIVOTHYM is currently ongoing to assess the combination of nivolumab plus ipilimumab.

Pan-Asian adapted ESMO Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with metastatic colorectal cancer

The European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with metastatic colorectal cancer (mCRC), published in late 2022, were adapted in December 2022, according to previously established standard methodology, to produce the Pan-Asian adapted (PAGA) ESMO consensus guidelines for the management of Asian patients with mCRC. The adapted guidelines presented in this manuscript represent the consensus opinions reached by a panel of Asian experts in the treatment of patients with mCRC representing the oncological societies of China (CSCO), Indonesia (ISHMO), India (ISMPO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO), co-ordinated by ESMO and the Japanese Society of Medical Oncology (JSMO). The voting was based on scientific evidence and was independent of the current treatment practices, drug access restrictions and reimbursement decisions in the different Asian countries. The latter are discussed separately in the manuscript. The aim is to provide guidance for the optimisation and harmonisation of the management of patients with mCRC across the different countries of Asia, drawing on the evidence provided by both Western and Asian trials, whilst respecting the differences in screening practices, molecular profiling and age and stage at presentation, coupled with a disparity in the drug approvals and reimbursement strategies, between the different countries.

Pan-Asian adapted ESMO Clinical Practice Guidelines for the diagnosis, staging and treatment of patients with metastatic breast cancer

The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, staging and treatment of patients with metastatic breast cancer (MBC) was published in 2021. A special, hybrid guidelines meeting was convened by ESMO and the Korean Society of Medical Oncology (KSMO) in collaboration with nine other Asian national oncology societies in May 2022 in order to adapt the ESMO 2021 guidelines to take into account the differences associated with the treatment of MBC in Asia. These guidelines represent the consensus opinions reached by a panel of Asian experts in the treatment of patients with MBC representing the oncological societies of China (CSCO), India (ISMPO), Indonesia (ISHMO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO). The voting was based on the best available scientific evidence and was independent of drug access or practice restrictions in the different Asian countries. The latter were discussed when appropriate. The aim of these guidelines is to provide guidance for the harmonisation of the management of patients with MBC across the different regions of Asia, drawing from data provided by global and Asian trials whilst at the same time integrating the differences in genetics, demographics and scientific evidence, together with restricted access to certain therapeutic strategies.
