ABSTRACT

OBJECTIVE: Psychological distress is common in men with testicular cancer (TC), and masculinities may work to explain this. This study aimed to compare masculinities and distress in TC and healthy control (HC) populations and explore relationships between correlates of distress (psychological flexibility and coping style) and masculinities in TC. METHODS: A cross-sectional, online survey was completed by 92 men with TC (Mage  = 34.8) and 90 HC (Mage  = 30.7). Measures included psychological distress (Patient-Reported Outcomes Measurement Information System Depression/Anxiety, fear of cancer recurrence inventory-short form), masculinities (gender role conflict-short form, inventory of subjective masculinity experiences/subjective masculinity stress scale, masculinity in chronic disease inventory), coping style (mini-mental adjustment to cancer ) and psychological flexibility (comprehensive assessment of acceptance commitment therapy). Linear regressions were conducted to compare groups and analyse associations. RESULTS: There were no differences in masculinities or psychological distress between populations (all p > 0.05 and all Cohen's d < 0.20), except for subjective masculine stress and restrictive affectionate behaviour between men. For men with TC, restrictive affection/emotion, conflicts between family/work and subjective masculine stress were associated with psychological distress (rs 0.21-0.58). Optimistic action was negatively associated with depression/anxiety, helplessness/hopelessness coping (rs -0.27 to -0.42) and positively associated with psychological flexibility (r = 0.35). CONCLUSIONS: Masculinities are implicated in psychological distress in men with TC. Psychological flexibility as well as leveraging masculine beliefs (e.g., optimistic action) may be modifiable targets to reduce distress in men with TC.

ABSTRACT

OBJECTIVE: Masculinities have been explored in men with testicular cancer (TC), though limited contemporary research is available on traditional masculine norms important to masculine self-perception. The purpose of this research was to explore the discourse of TC experience in relation to masculine self-perception. METHODS: A qualitative descriptive study was conducted consisting of semi-structured interviews with 21 men. Men were aged between 31 and 47 (Mage = 35.7). Most men were diagnosed with Stage 1 cancer (66.6%), all men had finished active treatment and time since diagnosis ranged from 17.3 to 71.8 months (M = 47.2). Independent coding was conducted by two researchers and was refined in coding meetings with authors. Themes were developed in a predominantly deductive manner, and analysis of themes was undertaken using a reflexive analysis approach. RESULTS: Traditional masculine norms showed differing relationships to masculine self-perception. Two main themes were identified [1] Maintained or enhanced masculine self-perception and [2] threats to masculine self-perception. Subthemes demonstrated that maintaining emotional control, strength and 'winning' was important to men, and reduced physical competencies (i.e., strength, sexual dysfunction, virility) challenged self-perception. Strict adherence to traditional norms in response to threatened self-perception related to psychological distress. CONCLUSION: Leveraging traditionally masculine norms such as physical strength and control and developing flexible adaptations of masculinities should be encouraged with men with TC to retain self-perception and potentially enable better coping. Masculine self-perception of gay/bisexual men may centre around sexual functioning, though further research is required.

ABSTRACT

International and national oncofertility networks, including the US-led Oncofertility Consortium, FertiProtekt, and the Danish Network, have played pivotal roles in advancing the discipline of oncofertility over the last decade. Many other countries lack a shared approach to pediatric oncofertility health service delivery. This study aims to describe baseline oncofertility practices at Australian New Zealand Children's Haematology/Oncology Group centers in 2019-2021, describe binational priorities for care, and propose a 5-year action plan for best practice to be implemented by the newly formed Australian New Zealand Consortium in Children, Adolescents, and Young Adults (CAYA) Oncofertility (ANZCO).

ABSTRACT

Worldwide advances in treatment and supportive care for children and adolescents with cancer have resulted in a increasing population of survivors growing into adulthood. Yet, this population is at very high risk of late occurring health problems, including significant morbidity and early mortality. Unique barriers to high-quality care for this group include knowledge gaps among both providers and survivors as well as fragmented health-care delivery during the transition from paediatric to adult care settings. Survivors of childhood and adolescent cancer are at risk for a range of late-occuring side-effects from treatment, including cardiac, endocrine, pulmonary, fertility, renal, psychological, cognitive, and socio-developmental impairments. Care coordination and transition to adult care are substantial challenges, but can be empowering for survivors and improve outcomes, and could be facilitated by clear, effective communication and support for self-management. Resources for adult clinical care teams and primary care providers include late-effects surveillance guidelines and web-based support services.

ABSTRACT

OBJECTIVE: To report treatment patterns and survival outcomes of patients with relapsed and refractory metastatic germ cell tumours (GCTs) treated with high-dose chemotherapy (HDCT) and autologous stem-cell transplantation in low-volume specialized centres within the widely dispersed populations of Australia and New Zealand between 1999 and 2019. PATIENTS AND METHODS: We conducted a retrospective analysis of 111 patients across 13 institutions. Patients were identified from the Australasian Bone Marrow Transplant Recipient Registry. We reviewed treatment regimens, survival outcomes, deliverability and toxicities. Primary endpoints included overall (OS) and progression-free survival (PFS). Cox proportional hazards models were used to test the association of survival outcomes with patient and treatment factors. RESULTS: The median (range) age was 30 (14-68) years and GCT histology was non-seminomatous in 84% of patients. International Prognostic Factors Study Group (IPFSG) prognostic risk category was very low/low, intermediate, high and very high in 18%, 36%, 25% and 21% of patients, respectively. Salvage conventional-dose chemotherapy (CDCT) was administered prior to HDCT in 59% of patients. Regimens included paclitaxel, ifosfamide, carboplatin and etoposide (50%), carboplatin and etoposide (CE; 28%), carboplatin, etoposide and ifosfamide (CEI; 6%), carboplatin, etoposide and cyclophosphamide (CEC; 5%), CEC-paclitaxel (6%) and other (5%). With a median follow-up of 4.4 years, the 1-, 2- and 5-year PFS rates were 62%, 57% and 52%, respectively, and OS rates were 73%, 65% and 61%, respectively. There were five treatment-related deaths. Progression on treatment occurred in 17%. In a univariable analysis, worse International Germ Cell Cancer Collaborative Group (IGCCCG) and IPFSG prognostic groups were associated with inferior survival outcomes. An association of inferior survival was not found with the number of high-dose cycles received nor when HDCT was delivered after salvage CDCT. CONCLUSION: This large dual-national registry-based study reinforces the efficacy and deliverability of HDCT for relapsed and refractory metastatic GCT in low-volume specialized centres in Australia and New Zealand, with survival outcomes comparable to those found in international practice.

ABSTRACT

OBJECTIVE: The purpose of this review was to synthesise the literature on the topic of masculinity and testicular cancer (TC) and investigate the relative impact of TC on men's view of their masculinity. METHODS: Searches were conducted across four databases (MEDline, PsycInfo, CINAHL Plus and Scopus) for articles published before April 2022 that included (1) TC and (2) masculinity. Two researchers independently rated studies for inclusion with a third resolving conflicts. Of the 6464 articles screened, 24 articles (10 quantitative and 14 qualitative) were included in the review. Articles were rated for quality and a narrative synthesis was performed. RESULTS: Overall, results indicated some men experience a shift in the way they relate to their sense of masculinity following diagnosis and treatment for TC. Being single and without children was related to the experience of negative masculinity-related outcomes, possibly due to a compounding lack of relational support and being unable to conform to protector, provider traditions. Men who described testicle loss as symbolic of their diminished masculinity were also negatively impacted. However, recent, high-quality literature on the topic using standardised masculinity measures was limited. CONCLUSION: Some men experience a reduced sense of masculinity after TC, however the impact of TC on masculinity remains person dependent. Further research using validated masculinity measures is required to uncover psycho-social variables that may account for whether and how meaning is made between TC and its treatment and any subsequent impact on perceived masculinity. Such factors may better support these men in life beyond cancer. SYSTEMATIC REVIEW REGISTRATION: PROSPERO. International Prospective Register of Systematic Reviews: CRD42020185649.

ABSTRACT

PURPOSE OF REVIEW: Testicular germ cell tumours (TGCTs) are the most common solid malignant cancer diagnosed in young males and the incidence is increasing. Understanding the genetic basis of this disease will help us to navigate the challenges of early detection, diagnosis, treatment, surveillance, and long-term outcomes for patients. RECENT FINDINGS: TGCTs are highly heritable. Current understanding of germline risk includes the identification of one moderate-penetrance predisposition gene, checkpoint kinase 2 ( CHEK2 ), and 78 low-to-moderate-risk single nucleotide polymorphisms identified in genome-wide-associated studies, which account for 44% of familial risk. Biomarker research in TGCTs has been challenging for multiple reasons: oncogenesis is complex, actionable mutations are uncommon, clonal evolution unpredictable and tumours can be histologically and molecularly heterogeneous. Three somatic mutations have thus far been identified by DNA exome sequencing, exclusively in seminomas: KIT, KRAS and NRAS . Several genetic markers appear to be associated with risk of TGCT and treatment resistance. TP53 mutations appear to be associated with platinum resistance. MicroRNA expression may be a useful biomarker of residual disease and relapse in future. SUMMARY: The biology of testicular germ cells tumours is complex, and further research is needed to fully explain the high heritability of these cancers, as well as the molecular signatures which may drive their biological behaviour.

ABSTRACT

INTRODUCTION: Current knowledge of the long-term health behaviours and well-being of adolescent and yong adult (AYA) cancer survivors is limited. The aim of this study was to evaluate the health behaviours of AYA cancer survivors compared to Australian normative data and describe their health-related quality of life (HR-QoL) and levels of fatigue. METHOD: A cross-sectional online survey of participants aged 15-25 years at diagnosis and 2-7 years post treatment completion was conducted at a comprehensive cancer centre. Validated questionnaires assessed health behaviours and functioning including current physical activity (PA) levels, diet quality, fatigue (FACIT-F) and HR-QoL (AQoL-6D, Short Form 36v2 [SF-36v2]) were compared to Australian normative data. RESULTS: Ninety individuals completed the survey (26% response rate) with a mean age of 25.4 years and median time post treatment of 61 months (24-85 months). Compared to normative data, a higher proportion of AYA cancer survivors was consuming the recommended daily serves of fruit and vegetables (16.7% vs. 3.9%, p < .0001), had a lower presence of overweight or obesity (46.7% vs. 57.7%, p = .04) and lower percentage of current smokers (2.2% vs. 16.7%, p < .0001). However, AYA cancer survivors reported increased fatigue (t[df = 596] = -4.1, p < .0001) and reduced HR-QoL compared to normative data (t[df = 533] = 9.2, p < .0001) along with a higher proportion suffering from one or more chronic health conditions (65% vs. 40%, p < .0001). CONCLUSION: AYA cancer survivors from a single Australian institution, who were on average 5 years post treatment, exhibited better health behaviours compared to Australian normative data, but still below recommended guidelines. However, they continue to experience issues with fatigue and reduced HR-QoL, especially in those not meeting the PA guidelines.

ABSTRACT

Cancer therapy related cardiac dysfunction (CTRCD) is an area of increasing focus, particularly during the survivorship period, for paediatric, adolescent and adult cancer survivors. With the advent of immunotherapy and targeted therapy, there is a new set of mechanisms from which paediatric and young adult patients with cancer may suffer cardiovascular injury. Furthermore, cardiovascular disease is the leading cause of morbidity and mortality in the survivorship period. The recently established Australian Cardio-Oncology Registry is the largest and only population-based cardiotoxicity database of paediatric and adolescent and young adult oncology patients in the world, and the first paediatric registry that will document cardiotoxicity caused by chemotherapy and novel targeted therapies using a prospective approach. The database is designed for comprehensive data collection and evaluation of the Australian practice in terms of diagnosis and management of CTRCD. Using the Australian Cardio-Oncology Registry critical clinical information will be collected regarding predisposing factors for the development of CTRCD, the rate of subclinical left ventricular dysfunction and transition to overt heart failure, further research into protectant molecules against cardiac dysfunction and aid in the discovery of which genetic variants predispose to CTRCD. A health economic arm of the study will assess the cost/benefit of both the registry and cardio-oncology clinical implementation. Finally, an imaging arm will establish if exercise cardiac magnetic resonance imaging and VO2 max testing is a more sensitive predictor of cardiac reserve in paediatric and adolescent and young adult oncology patients exposed to cardiac toxic therapies.

ABSTRACT

Genetic counselors have long recognized the challenges of working with adolescents and young adults (AYA) and their families. In 2010, a framework of Youth-friendly Genetic Counseling was developed by an expert reference group with the aim to improve both care for AYAs and the experience of health professionals delivering that care. Subsequently, an education workshop was developed aimed to upskill genetic health professionals in youth-friendly genetic counseling. The workshop was piloted with genetic counselors in Australia and New Zealand. A purpose designed, pre- and post-workshop survey and post-workshop focus group was utilized for evaluation. Mean confidence scores increased pre- and post-workshop. Participants also demonstrated increases in knowledge regarding: adolescent development; developmental theory; social factors impacting on health; the needs of young people; practice challenges; youth-friendly engagement, communication, consent and confidentiality; practice approaches; principles of adolescent healthcare; ethical issues; and available services and resources. Focus group data revealed several themes relating to practice challenges, learning gains, barriers, and enablers to clinical translation and workshop feedback. Results demonstrate utility of the workshop in up-skilling genetic health professionals in the provision of youth-friendly genetic counseling. Consideration of adaptation and sustainability, by embedding this theoretical and skills-based workshop as a module within genetic counseling education, is required to ensure practice competence and the best health outcomes for young people and their families.

ABSTRACT

It has been historically uncertain if extra centrosomes are a cause or consequence of tumorigenesis. Experiments have recently established that overexpression of polo-like kinase 4 (PLK4) promotes centrosome amplification with consequential promotion of cellular aneuploidy. Furthermore, centrosome amplification drives spontaneous tumorigenesis in mice. Tissues lacking normal functional p53 tolerate extra centrosomes, whereas p53 proficient tissues initiate proliferative arrest in this circumstance. Extra centrosomes trigger activation of the multi-protein PIDDosome complex, with Caspase-2 effecting cleavage of the p53-negative regulator mouse double minute 2, consequent stabilization of p53 and p21-dependent arrest of the cell cycle. The co-occurrence of cellular aneuploidy, complex chromosomal rearrangements and p53 dysfunction is a striking feature of some osteosarcomas. It is postulated that small-molecule PLK4 inhibitors such as CFI-400945, which are in development, may have utility in osteosarcoma given these findings.

ABSTRACT

There are limited data regarding the molecular characterization of undifferentiated pleomorphic sarcomas (UPS; formerly malignant fibrous histiocytoma). This study aimed to investigate the utility of next generation sequencing (NGS) in UPS to identify subsets of patients who harbour actionable mutations. Patients diagnosed with UPS underwent pathological re-evaluation by a pathologist specializing in sarcoma. Tumor DNA was isolated from archived fresh frozen tissue samples and genotyped using NGS with the Illumina MiSeq TruSeq Amplicon Cancer Panel (48 genes, 212 amplicons). In total, 95 patients initially classified with UPS were identified. Following pathology re-review the histological subtypes were reclassified to include: Myxofibrosarcoma (MFS, N = 44); UPS(N = 18); and Others (N = 27; including undifferentiated spindle cell sarcoma (N = 15) and dedifferentiated liposarcoma (N = 6)). Seven cases were excluded from further analysis for other reasons. Baseline demographics of the finalized cohort (N = 88) showed a median age of 66 years (32-95), primarily with stage I-III disease (92%) and high-grade (86%) lesions. Somatic mutations were identified in 31 cases (35%)(Total mutations = 36: solitary mutation(n = 27); two mutations( =n = 3); three mutations(n = 1)). The most commonly identified mutations were in TP53 (n = 24), ATM (n = 3) and PIK3CA (n = 2). Three of 43 patients with MFS and one of 18 patients with UPS had clinically relevant mutations, mainly related to biomarkers of prediction of response; however few had targetable driver mutations. Somatic mutation status did not influence disease free or overall survival. Based on the small number of clinically relevant mutations, these data do not support the routine use of targeted NGS panels outside of research protocols in UPS.

ABSTRACT

BACKGROUND: Adolescent and young adults (AYA) enrolment rates into cancer clinical trials (CCT) are the lowest of any age group globally. As AYA have distinct biological, psychosocial and relational needs, we aimed to explore any unique factors influencing their CCT decision-making process, including AYA-specific perceptions or attitudes towards CCT. METHODS: Qualitative interpretive descriptive methodology was used to explore AYA perceptions and decision-making related to CCT. An analytic approach conducive to inductive imagining and exploratory questioning was used in order to generate insights and interpret data. RESULTS: A total of 21 AYA were interviewed (median age: 31 (18-39)). Twelve (57%) participants had previously been approached to participate in CCT. Major themes influencing trial enrolment decisions were: 1) severity of illness/urgency for new treatment 2) side effect profile of investigational drug in the short and long term (e.g., impact on future quality of life) 3) who approached patient for trial participation (oncologist vs. other) 4) additional information found on-line about the trial and investigators, and 5) family, friends and peer group opinion regarding the CCT. CONCLUSIONS: Several psychosocial and relational factors were identified as influencing AYA CCT decisions, some of which are unique to this demographic. Specific strategies to address barriers to CCT and enable supportive decision-making include: 1) involving family in decision-making and 2) helping AYA appreciate short- and long-term implications of trial participation. Finally, exploring social networking and general education about CCT that AYA can independently access may increase participation.

ABSTRACT

OBJECTIVES: To identify differentially expressed genes between relapsed and non-relapsed clinical stage I testicular germ cell tumours (TGCTs). MATERIALS AND METHODS: We reviewed patients with clinical stage I non-seminoma and seminoma from an institutional database (2000-2012) who were managed by active surveillance. Patients with non-relapsed non-seminoma and non-relapsed seminoma were defined as being relapse-free after 2 and 3 years of surveillance, respectively. RNA extraction and gene expression analysis was performed on archival primary tumour samples and gene-set enrichment analysis (GSEA) was conducted in order to identify differentiating biological pathways. RESULTS: A total of 57 patients (relapsed non-seminoma, n = 12; relapsed seminoma, n =15; non-relapsed non-seminoma, n = 15; non-relapsed seminoma, n = 15) were identified, with a median (range) relapse time of 5.6 (2.5-18.1) and 19.3 (4.7-65.3) months in the relapsed non-seminoma and relapsed seminoma cohorts, respectively. A total of 1 039 differentially expressed genes were identified that separated relapsed and non-relapsed groups. In patients with relapse, GSEA revealed enrichment in pathways associated with differentiation, such as skeletal development (i.e. FGFR1, BMP4, GLI2, SPARC, COL2A1), tissue (i.e. BMP4, SPARC, COL13A1) and bone remodelling (i.e. CARTPT, GLI2, MGP). A discriminative gene expression profile between relapsed and non-relapsed cases was discovered when combining non-seminoma and seminoma samples using 10- and 30-probe signatures; however, this profile was not observed in the seminoma and non-seminoma cohorts individually. CONCLUSION: A discriminating signature for relapsed disease was identified for clinical stage I TGCT that we were not able to identify by histology alone. Further validation is required to determine if this signature provides independent prognostic information to standard pathological risk factors.

ABSTRACT

PURPOSE: Minimal data exist regarding documentation of therapy-associated infertility risk (IR) and fertility preservation (FP) options during the initial oncology consultation prior to systemic therapy. This study investigated factors affecting IR/FP documentation and assessed the effect of implementation of an Adolescent and Young Adult (AYA) program on documentation rates. METHODS: A retrospective review of charts of patients receiving gonadotoxic therapy was undertaken for documentation of IR/FP pre- and post-implementation of an AYA program. Change in documentation rates was assessed using univariate and multiple logistic regression. RESULTS: A total of 173 charts were reviewed. On univariate analysis, IR/FP documentation was less likely if patients had metastatic disease (P < 0.01, P < 0.01), by tumor type (P < 0.01, P < 0.01), received less intensive chemotherapy (P = 0.03, P = 0.06), were older (P = 0.14, P < 0.01), had more children (P < 0.01, P < 0.01), or lacked AYA program involvement (P < 0.01, P < 0.01). FP discussion was more common in males (P = 0.02). On multivariable analysis, more children (P = 0.01, P = 0.03), older age (P < 0.01, P < 0.01), tumor type (P < 0.01, P = 0.01), stage (P = 0.02, NS), relationship (P = 0.03, NS), and lack of AYA involvement (P < 0.01, P < 0.01) were associated with lower rates of IR/FP documentation. Following AYA program implementation, IR/FP rates increased from 56% (CI 46-65%) to 85% (CI 74-92%, P < 0.01) and 54% (CI 45-64%) to 86% (CI 75-93%, P < 0.01), respectively. The effect of AYA program implementation on IR/FP documentation was most noticeable in leukemia, lymphoma, and breast groups (P < 0.01). CONCLUSIONS: Implementing an AYA consultation service at an adult cancer institution had a positive effect on the rates of IR/FP documentation. Specific programming can improve service delivery to AYA cancer patients, and fertility counseling should be integrated for patients undergoing gonadotoxic therapy.

ABSTRACT

PURPOSE OF REVIEW: Although significant strides have been made in genome sequencing technology, target-drug matching remains challenging. This article highlights the difficulties associated with patients accessing targeted drugs based on genomic information, and some proposed solutions. RECENT FINDINGS: Although cancers are increasingly stratified according to molecular subgroups, challenges remain in improving patient outcome based on drug-target matching. Before a drug-target match is even proposed, significant expertise is required of the clinician to interpret genomic information. Once a potential match is made, barriers remain for patients to access treatment via clinical trials, as approved agents on-label or off-label, or through expanded access programs. Solutions to improve drug accessibility are actively being investigated. Several prospective trials using molecular characterization as an entry to access target-drug matching are underway. For those unable to access target-drug matching on trial, proposals for a facilitated access program and registry have been suggested. SUMMARY: Although improvements have been made in the drug development and approval timelines, drug accessibility based on molecular characterization remains problematic. However, with the emergence of novel trial designs, and efforts to enhance drug access outside of clinical trial settings, opportunities for drug-target matching are improving.

ABSTRACT

PURPOSE: Small cell cancers (SmCC), whether pulmonary (SCLC) or extrapulmonary, have a poor prognosis unless localised at diagnosis. Given a proportion of these cancers express somatostatin receptor subtype 2 (SSTR2), we aimed to investigate the efficacy of targeted peptide receptor chemoradionuclide therapy (PRCRT). METHODS: In this preclinical study, we used a SCLC xenograft mouse model with high expression of SSTR2 to investigate the effect of peptide receptor radionuclide therapy (PRRT) with chemotherapy compared to either alone. We subsequently explored the clinical utility in a patient with SmCC with high SSTR expression treated with PRCRT. RESULTS: Robust expression of SSTR2 in NCI-H69 SCLC xenografts was documented by (68)Ga-DOTA-octreotate (GaTate) (tumour to background uptake ratio = 35). The combination of PRRT using (177)Lu-DOTA-octreotate (LuTate) with carboplatin/etoposide (C/E) chemotherapy was more effective than either LuTate or C/E alone for regression of the NCI-H69 model (p value < 0.05). PRCRT was associated with significantly prolonged survival versus PRRT (p value = 0.0001) or chemotherapy alone (p value = 0.0058). In the subsequent case study, a patient with relapsed SmCC with high SSTR2 expression on GaTate PET underwent PRCRT with radiosensitising etoposide with evidence of a complete metabolic response for 4 months. CONCLUSION: Given the limited treatment options in this setting, PRCRT is a promising therapeutic option for SSTR2-expressing SmCC.

ABSTRACT

Sarcomas are a rare and diverse set of cancers that disproportionately affect young people. The best possible outcome depends on access to highly specialised, multidisciplinary care. Although advances have been made in therapeutic techniques, access to some treatments might be limited by cost implications. This Review proposes an evidence-based, consensus recommendation for optimum management of bone and soft-tissue sarcoma across the Asia-Pacific region, taking into account variation in health-care resources, stratified according to the Breast Health Global Initiative resource levels. A web-based survey of 89 clinicians involved in the care of patients with sarcoma from 18 Asia-Pacific countries generated the recommendations for diagnosis, staging, and management, including supportive and palliative care, and research.

ABSTRACT

Primary aortic angiosarcomas (PAA) are rare angiosarcomas, frequently diagnosed in advanced stages due to initial misdiagnosis. This case describes a 66-year-old woman, initially presenting with a distal thoracic aorta thrombus and symptomatic bilateral popliteal emboli. Despite initial management and therapeutic anticoagulation, she experienced progressive lower limb claudication and 12 months following initial presentation she re-presented with an obstructing distal thoracic aorta mass and metastatic disease. Histopathology confirmed metastatic epithelioid angiosarcoma. Despite urgent palliative radiotherapy, she died 6 weeks after diagnosis from complications of tumour thromboembolism. Suspicion for PAA should be raised in the case of thrombus in atypical segments (e.g. thoracic aorta) or progressive course despite anticoagulation. Multimodal imaging including MRI and FDG-PET is useful to distinguish from benign aetiologies.
