RESUMO

PURPOSE: Timely access to supportive and palliative care (PC) remains a challenge. A proposed solution is to trigger an automatic referral process to PC by pre-determined clinical criteria. This study sought to co-design with patients and providers an automatic PC referral process for patients newly diagnosed with stage IV lung cancer. METHODS: In Step 1 of this work, nine one on one phone interviews were conducted with advanced lung cancer patients on their perspectives on the acceptability of phone contact by a specialist PC provider triggered by an automatic referral process. Interviews were thematically analysed. Step 2: Patient advisors, healthcare providers (oncologists, nurses from oncology and PC, clinical social worker, psychologist), and researchers were invited to join a working group to provide input on the development and implementation of the automatic referral process. The group met biweekly (virtually) over the course of six months. RESULTS: From interviews, the concept of an automatic referral process was perceived to be acceptable and beneficial for patients. Participants emphasized the need for timely support, access to peer and community resources. Using these findings, the co-design working group identified eligibility criteria for identifying newly diagnosed stage IV lung cancer patients using the cancer centre electronic health record, co-developed a telephone script for specialist PC providers, handouts on supportive care, and interview and survey guides for evaluating the implemented automatic process. CONCLUSION: A co-design process ensures stakeholders are involved in program development and implementation from the very beginning, to make outputs relevant and acceptable for stage IV lung cancer patients.

RESUMO

This protocol details the propagation and passaging of human iPSCs and their differentiation into osteoclasts. First, iPSCs are dissociated into a single-cell suspension for further use in embryoid body induction. Following mesodermal induction, embryoid bodies undergo hematopoietic differentiation, producing a floating hematopoietic cell population. Subsequently, the harvested hematopoietic cells undergo a macrophage colony-stimulating factor maturation step and, finally, osteoclast differentiation. After osteoclast differentiation, osteoclasts are characterized by staining for TRAP in conjunction with a methyl green nuclear stain. Osteoclasts are observed as multinucleated, TRAP+ polykaryons. Their identification can be further supported by Cathepsin K staining. Bone and mineral resorption assays allow for functional characterization, confirming the identity of bona fide osteoclasts. This protocol demonstrates a robust and versatile method to differentiate human osteoclasts from iPSCs and allows for easy adoption in applications requiring large quantities of functional human osteoclasts. Applications in the areas of bone research, cancer research, tissue engineering, and endoprosthesis research could be envisioned.

RESUMO

Multiplexed assays of variant effect are powerful tools for assessing the impact of protein sequence variation, but are limited to measuring a single protein property and often rely on indirect readouts of intracellular protein function. Here, we developed LAbeling with Barcodes and Enrichment for biochemicaL analysis by sequencing (LABEL-seq), a platform for the multimodal profiling of thousands of protein variants in cultured human cells. Multimodal measurement of ~20,000 variant effects for ~1,600 BRaf variants using LABEL-seq revealed that variation at positions that are frequently mutated in cancer had minimal effects on folding and intracellular abundance but could dramatically alter activity, protein-protein interactions, and druggability. Integrative analysis of our multimodal measurements identified networks of positions with similar roles in regulating BRaf's signaling properties and enabled predictive modeling of variant effects on complex processes such as cell proliferation and small molecule-promoted degradation. LABEL-seq provides a scalable approach for the direct measurement of multiple biochemical effects of protein variants in their native cellular context, yielding insight into protein function, disease mechanisms, and druggability.

RESUMO

(1) Background: This observational cohort study describes the frequency, content, and satisfaction with advance care planning (ACP) conversations with healthcare providers (HCPs), as reported by patients with advanced colorectal cancer. (2) Methods: The patients were recruited from two tertiary cancer centers in Alberta, Canada. Using the My Conversations survey with previously validated questions, the patients were asked about specific ACP elements discussed, with which HCPs these elements were discussed, their satisfaction with these conversations, and whether they had a goals of care designation (GCD) order. We surveyed and analyzed data from the following four time points: enrollment, months 1, 2, and 3. (3) Results: In total, 131 patients were recruited. At enrollment, 24% of patients reported discussing at least one ACP topic. From enrollment to month 3, patients reported a high frequency of discussions (80.2% discussed fears, 71.0% discussed prognosis, 54.2% discussed treatment preferences at least once); however, only 44.3% of patients reported discussing what is important to them in considering health care preferences. Patients reported having ACP conversations most often with their oncologists (84.7%) and cancer clinic nurses (61.8%). Patients reported a high level of satisfaction with their ACP conversations, with over 80% of patients reported feeling heard and understood. From enrollment to month 3, there was an increase in the number of patients with a GCD order from 53% to 74%. (4) Conclusions: Patients reported more frequent conversations compared to the literature and clinical documentation. While the satisfaction with these conversations is high, there is room for quality improvement, particularly in eliciting patients' personal goals for their treatment.

RESUMO

OBJECTIVES: The Serious Illness Conversation Guide (SICG) has emerged as a framework for conversations with patients with a serious illness diagnosis. This study reports on narratives generated from open-ended questions of a novel assessment tool, the Serious Illness Conversation-Evaluation Exercise (SIC-Ex), to assess resident-led conversations with patients in oncology outpatient clinics. DESIGN: Qualitative study using template analysis. SETTING: Three academic cancer centres in Canada. PARTICIPANTS: 7 resident physicians (trainees), 7 patients from outpatient cancer clinics, 10 preceptors (raters) consisting of medical oncologists, palliative care physicians and radiation oncologists. INTERVENTIONS: Each trainee conducted an SIC with a patient, which was videotaped. The raters watched the videos and evaluated each trainee using the novel SIC-Ex and the reference Calgary-Cambridge Guide (CCG) initially and again 3 months later. Two independent coders used template analysis to code the raters' narrative comments and identify themes/subthemes. OUTCOME MEASURES: How narrative comments aligned with elements of the CCG and SICG. RESULTS: Template analysis yielded four themes: adhering to SICG, engaging patients and family members, conversation management and being mindful of demeanour. Narrative comments identified numerous verbal and non-verbal elements essential to SICG. Some comments addressing general skills in engaging patients/families and managing the conversation (eg, setting agenda, introduction, planning, exploring, non-verbal communication) related to both the CCG and SICG, whereas other comments such as identifying substitute decision maker(s), affirming commitment and introducing Advance Care Planning were specific to the SICG. CONCLUSIONS: Narrative comments generated by SIC-Ex provided detailed and nuanced insights into trainees' competence in SIC, beyond the numerical ratings of SIC-Ex and the general communication skills outlined in the CCG, and may contribute to a more fulsome assessment of SIC skills.

RESUMO

Kinase inhibitors are effective cancer therapies, but resistance often limits clinical efficacy. Despite the cataloging of numerous resistance mutations, our understanding of kinase inhibitor resistance is still incomplete. Here, we comprehensively profiled the resistance of ∼3,500 Src tyrosine kinase mutants to four different ATP-competitive inhibitors. We found that ATP-competitive inhibitor resistance mutations are distributed throughout Src's catalytic domain. In addition to inhibitor contact residues, residues that participate in regulating Src's phosphotransferase activity were prone to the development of resistance. Unexpectedly, we found that a resistance-prone cluster of residues located on the top face of the N-terminal lobe of Src's catalytic domain contributes to autoinhibition by reducing catalytic domain dynamics, and mutations in this cluster led to resistance by lowering inhibitor affinity and promoting kinase hyperactivation. Together, our studies demonstrate how drug resistance profiling can be used to define potential resistance pathways and uncover new mechanisms of kinase regulation.

RESUMO

BACKGROUND: Ever since their discovery, induced pluripotent stem cells (iPSCs) have been extensively differentiated into a large variety of cell types. However, a limited amount of work has been dedicated to differentiating iPSCs into osteoclasts. While several differentiation protocols have been published, it remains unclear which protocols or differentiation methods are preferable regarding the differentiation of osteoclasts. METHODS: In this study, we compared the osteoclastogenesis capacity of a peripheral blood mononuclear cell (PBMC)-derived iPSC line to a fibroblast-derived iPSC line in conjunction with either embryoid body-based or monolayer-based differentiation strategies. Both cell lines and differentiation protocols were investigated regarding their ability to generate osteoclasts and their inherent robustness and ease of use. The ability of both cell lines to remain undifferentiated while propagating using a feeder-free system was assessed using alkaline phosphatase staining. This was followed by evaluating mesodermal differentiation and the characterization of hematopoietic progenitor cells using flow cytometry. Finally, osteoclast yield and functionality based on resorptive activity, Cathepsin K and tartrate-resistant acid phosphatase (TRAP) expression were assessed. The results were validated using qRT-PCR throughout the differentiation stages. RESULTS: Embryoid body-based differentiation yielded CD45+, CD14+, CD11b+ subpopulations which in turn differentiated into osteoclasts which demonstrated TRAP positivity, Cathepsin K expression and mineral resorptive capabilities. This was regardless of which iPSC line was used. Monolayer-based differentiation yielded lower quantities of hematopoietic cells that were mostly CD34+ and did not subsequently differentiate into osteoclasts. CONCLUSIONS: The outcome of this study demonstrates the successful differentiation of osteoclasts from iPSCs in conjunction with the embryoid-based differentiation method, while the monolayer-based method did not yield osteoclasts. No differences were observed regarding osteoclast differentiation between the PBMC and fibroblast-derived iPSC lines.

RESUMO

BACKGROUND: The Palliative Care Early and Systematic (PaCES) program implemented an early palliative care pathway for advanced colorectal cancer patients in January 2019, to increase specialist palliative care consultation and palliative homecare referrals more than three months before death. This study aimed to understand the experience of patients with advanced colorectal cancer and family caregivers who received early palliative care supports from a specialist palliative care nurse and compared those experiences with participants who experienced standard oncology care prior to implementation of early palliative care. METHODS: This was a qualitative and patient-oriented study. We conducted semi-structured telephone interviews with two cohorts of patients with advanced colorectal cancer before and after implementation of an early palliative care pathway. We conducted a thematic analysis of the transcripts guided by a Person-Centred Care Framework. RESULTS: Seven patients living with advanced colorectal cancer and five family caregivers who received early palliative care supports expressed that visits from their early palliative care nurse was helpful, improved their understanding of palliative care, and improved their care. Four main themes shaped their experience of early palliative care: care coordination, perception of palliative care & advance care planning, coping with advanced cancer, and patient and family engagement. These findings were compared with experiences of 15 patients and seven caregivers prior to pathway implementation. CONCLUSION: An early palliative care pathway can improve advanced cancer care, and improve understanding and acceptance of early palliative care. This work was conducted in the context of colorectal cancer but may have relevance for the care of other advanced cancers.

RESUMO

OBJECTIVE: To examine the predictors, treatments, and outcomes of the use of palliative care in patients hospitalized with acute myocardial infarction (AMI) who had a do-not-resuscitate (DNR) order. PATIENTS AND METHODS: Using the National (Nationwide) Inpatient Sampling database for 2015-2018, we examined the predictors, in-hospital procedures, and outcomes of palliative care recipients among patients with AMI who had a DNR order. RESULTS: We identified 339,270 admissions with AMI that had a DNR order, including patients who received palliative care (n=113,215 [33.4%]). Compared with patients who did not receive palliative care, these patients were more frequently younger (median age, 81 vs 83 years; P<.001), were less likely to be female (50.9% [57,626 of 113,215] vs 54.7% [123,652 of 226,055]; P<.001), and were more likely to present with cardiac arrest (11.6% [13,133 of 113,215] vs 6.9% [15,598 of 226,055]; P<.001). Patients were more likely to receive palliative care at a large (odds ratio [OR], 1.47; 95% CI, 1.44 to 1.50) or teaching (OR, 2.10; 95% CI, 2.04 to 2.16) hospitals compared with small or rural ones. Patients receiving palliative care were less likely to be treated invasively, with reduced rates of invasive coronary angiography (OR, 0.46; 95% CI, 0.45 to 0.47) and percutaneous coronary intervention (OR, 0.47; 95% CI, 0.45 to 0.48), and were more likely to die in the hospital (52.4% [59,325 of 113,215] vs 22.9% [51,766 of 226,055]). CONCLUSION: In patients who had a DNR status and were hospitalized and received a diagnosis of AMI, only one-third received palliative care.

RESUMO

BACKGROUND: The Goals of Care Designation (GCD) is a medical order used to communicate the focus of a patient's care in Alberta, Canada. In this study, we aimed to determine the association between GCD type (resuscitative, medical or comfort) and resource use during hospitalization. METHODS: This was a prospective cohort study of newly hospitalized inpatients in Alberta conducted from January to September 2017. Participants were aged 55 years or older with chronic obstructive pulmonary disease, congestive heart failure, cirrhosis, cancer or renal failure; aged 55-79 years and their provider answered "no" to the "surprise question" (i.e., provider would not be surprised if the patient died in the next 6 months); or aged 80 years or older with any acute condition. The exposure of interest was GCD. The primary outcome was health care resource use during admission, measured by length of stay (LOS), intensive care unit hours, Resource Intensity Weights (RIWs), flagged interventions and palliative care referral. The secondary outcome was 30-day readmission. Adjusted regression analyses were performed (adjusted for age, sex, race and ethnicity, Clinical Frailty Scale score, comorbidities and city). RESULTS: We included 475 study participants. The median age was 83 (interquartile range 77-87) years, and 93.7% had a GCD at enrolment. Relative to patients with the resuscitative GCD type, patients with the medical GCD type had a longer LOS (1.42 times, 95% confidence interval [CI] 1.10-1.83) and a higher RIW (adjusted ratio 1.14, 95% CI 1.02-1.28). Patients with the comfort and medical GCD types had more palliative care referral (comfort GCD adjusted relative risk (RR) 9.32, 95% CI 4.32-20.08; medical GCD adjusted RR 3.58, 95% CI 1.75-7.33) but not flagged intervention use (comfort GCD adjusted RR 1.06, 95% CI 0.49-2.28; medical GCD adjusted RR 0.98, 95% CI 0.48-2.02) or 30-day readmission (comfort GCD adjusted RR 1.00, 95% CI 0.85-1.19; medical GCD adjusted RR 1.05, 95% CI 0.97-1.20). INTERPRETATION: Goals of Care Designation type early during admission was associated with LOS, RIW and palliative care referral. This suggests an alignment between health resource use and the focus of care communicated by each GCD.

RESUMO

Background: Palliative care (PC) is an added layer of support provided concurrently with cancer care and serves to improve wellbeing and sustain quality of life. Understanding what is meaningful and a priority to patients, their families, and caregivers with lived experience of cancer and PC is critical in supporting their needs and improving their care provision. However, the impacts of engaging cancer patients within the context of PC research remain unknown. Objective: To examine the impacts of engaging individuals with lived experience of cancer and PC as partners in PC research. Methods: An a priori systematic review protocol was registered with PROSPERO (CRD42021286744). Four databases (APA PsycINFO, CINAHL, EMBASE, and MEDLINE) were searched and only published, peer-reviewed primary English studies aligned with the following criteria were included: (1) patients, their families, and/or caregivers with lived experience of cancer and PC; (2) engaged as partners in PC research; and (3) reported the impacts of engaging cancer PC patient partners in PC research. We appraised the quality of eligible studies using the Critical Appraisal Skills Program (CASP) and GRIPP2 reporting checklists. Results: Three studies that included patient partners with lived experience of cancer and PC engaged at all or several of the research stages were identified. Our thematic meta-synthesis revealed impacts (benefits and opportunities) on patient partners (emotional, psychological, cognitive, and social), the research system (practical and ethical) and health care system (service improvements, bureaucratic attitudes, and inaction). Our findings highlight the paucity of evidence investigating the impacts of engaging patients, their families and caregivers with lived experience of cancer and PC, as partners in PC research. Conclusions: The results of this review and meta-synthesis can inform the more effective design of cancer patient partnerships in PC research and the development of feasible and effective strategies given the cancer and PC context patient partners are coming from.

RESUMO

The Serious Illness Care Program (SICP), designed by Ariadne Labs, is a multicomponent intervention to improve conversations about values and goals for patients with a life-limiting illness. In oncology, implementation of the SICP achieved more, earlier, and better-quality conversations and reduced anxiety and depression among patients with advanced cancer. In this commentary, we describe the SICP, including results from the cluster-randomized trial, provide examples of real-world implementation of this program, and highlight ongoing challenges and barriers that are preventing widespread adoption of this intervention into routine practice. For the SICP to be successfully embedded into routine patient care, it will require significant effort, including ongoing leadership support and training opportunities, champions from all sectors of the interdisciplinary team, and adaptation of the program to a wider range of patients. Future research should also investigate how early conversations can be translated into personalized care plans for patients.

RESUMO

OBJECTIVES: To develop and validate a values clarification tool, the Short Graphic Values History Tool (GVHT), designed to support person-centred decision making during serious illness. METHODS: The development phase included input from experts and laypersons and assessed acceptability with patients/family members. In the validation phase, we recruited additional participants into a before-after study. Our primary validation hypothesis was that the tool would reduce scores on the Decisional Conflict Scale (DCS) at 1-2 weeks of follow-up. Our secondary validation hypotheses were that the tool would improve values clarity (reduce scores) more than other DCS subscales and increase engagement in advance care planning (ACP) processes related to identification and discussion of one's values. RESULTS: In the development phase, the tool received positive overall ratings from 22 patients/family members in hospital (mean score 4.3; 1=very poor; 5=very good) and family practice (mean score 4.5) settings. In the validation phase, we enrolled 157 patients (mean age 71.8 years) from family practice, cancer clinic and hospital settings. After tool completion, decisional conflict decreased (-6.7 points, 95% CI -11.1 to -2.3, p=0.003; 0-100 scale; N=100), with the most improvement seen in the values clarity subscale (-10.0 points, 95% CI -17.3 to -2.7, p=0.008; N=100), and the ACP-Values process score increased (+0.4 points, 95% CI 0.2 to 0.6, p=0.001; 1-5 scale; N=61). CONCLUSIONS: The Short GVHT is acceptable to end users and has some measure of validity. Further study to evaluate its impact on decision making during serious illness is warranted.

RESUMO

Little is known about how frequently do-not-resuscitate (DNR) orders are placed in patients with acute myocardial infarction (AMI), the types of patients in which they are placed, treatment strategies or clinical outcomes of such patients. Using the United States (US) National Inpatient Sample (NIS) database from 2015 to 2018, we identified 2,767,549 admissions that were admitted to US hospitals and during the hospitalization received a principle diagnosis of AMI, of which 339,270 (12.3%) patients had a DNR order (instigated both preadmission and during in-hospital stay). Patients with a DNR status were older (median age 83 vs 65, p < 0.001), more likely to be female (53.4% vs 39.3%, p < 0.001) and White (81.0% vs 73.3%, p < 0.001). Predictors of DNR status included comorbidities such as heart failure (OR: 1.47, 95% CI: 1.45 to 1.48), dementia (OR: 2.53, 95% CI: 2.50 to 2.55), and cancer. Patients with a DNR order were less likely to undergo invasive management or be discharged home (13.5% vs 52.8%), with only 1/3 receiving palliative consultation. In hospital mortality (32.7% vs 4.6%, p < 0.001) and MACCE (37.1% vs 8.8%, p < 0.001) were higher in the DNR group. Factors independently associated with in-hospital mortality among patients with a DNR order included a STEMI presentation (OR: 2.90, 95% CI: 2.84 to 2.96) and being of Black (OR: 1.29, 95% CI: 1.26 to 1.33), Hispanic (OR: 1.36, 95% CI: 1.32 to 1.41) or Asian/Pacific Islander (OR: 1.56, 95% CI:1.49-race. In conclusion, AMI patients with a DNR status were older, multimorbid, less likely to receive invasive management, with only one third of patients with DNR status referred for palliative care.

RESUMO

Despite the known benefits, healthcare systems struggle to provide early, integrated palliative care (PC) for advanced cancer patients. Understanding the barriers to providing PC from the perspective of oncology clinicians is an important first step in improving care. A 33-item online survey was emailed to all oncology clinicians working with all cancer types in Alberta, Canada, from November 2017 to January 2018. Questions were informed by Michie's Theoretical Domains Framework and Behaviour Change Wheel (BCW) and queried (a) PC provision in oncology clinics, (b) specialist PC consultation referrals, and (c) working with PC consultants and home care. Respondents (n = 263) were nurses (41%), physicians (25%), and allied healthcare professionals (18%). Barriers most frequently identified were "clinicians' limited time/competing priorities" (64%), "patients' negative perceptions of PC" (63%), and clinicians' capability to manage patients' social issues (63%). These factors mapped to all three BCW domains: motivation, opportunity, and capability. In contrast, the least frequently identified barriers were clinician motivation and perceived PC benefits. Oncology clinicians' perceptions of barriers to early PC were comparable across tumour types and specialties but varied by professional role. The main challenges to early integrated PC include all three BCW domains. Notably, motivation is not a barrier for oncology clinicians; however, opportunity and capability barriers were identified. Multifaceted interventions using these findings have been developed, such as tip sheets to enhance capability, reframing PC with patients, and earlier specialist PC nursing access, to enhance clinicians' use of and patients' benefits from an early PC approach.

RESUMO

BACKGROUND: Patient videos about advance care planning (ACP; hereafter "Videos"), were developed to support uptake of provincial policy and address the complexity of patients' decision-making process. We evaluate self-administered ACP Videos, compare the studies' choice of outcomes, show correlations between the patients' ACP actions, and discuss implications for health care policy. OBJECTIVE: To test the efficacy of the Videos on patients' ACP/goals of care designation conversations with a health care provider. DESIGN, SETTING, AND PARTICIPANTS: Using a 2-arm, 1:1 randomized controlled trial, we recruited outpatients with a diagnosis of kidney failure, heart failure, metastatic lung, gastrointestinal, or gynecological cancer from 22 sites. Analysis followed the intention-to-treat principle. INTERVENTIONS: Videos describing the ACP process and illustrating the resuscitative, medical, and comfort levels of care. MAIN OUTCOMES AND MEASURES: The primary outcome was the proportion of participants who reported having an ACP/goals of care designation (GCD) conversation with a health care provider by 3 mo. Outcomes were measured using the Behaviours in Advance Care Planning and Actions Survey, an online survey capturing ACP attitudes, processes, and actions. RESULTS: We analyzed 241 and 217 participants at baseline and 3 mo, respectively. The proportion of participants who had an ACP/GCD conversation with a health care provider by 3 mo was significantly different between study arms (46% intervention; 32% control; adjusted odds ratio, 1.83; P = 0.032). Adjusted for the quality of conversations, there was no significant difference. CONCLUSIONS: Videos as stand-alone tools do not engage individuals in high-quality ACP. Pragmatic trials are necessary to evaluate their impact on downstream outcomes when integrated into intentional, comprehensive conversations with a health care provider. Considering the strong correlation between 2 activities (physicians discussing options, patients telling health care providers preferences), policy should focus on empowering patients to initiate these conversations.

RESUMO

Purpose: Guidelines suggest that advance care planning (ACP) and goals-of-care discussions should be conducted for patients with advanced cancer early in the course of their disease. A recent audit of our health system found that these discussions were rarely being documented in the electronic medical record (EMR). We conducted a quality improvement initiative to improve rates of documentation of goals and wishes among patients with advanced cancer. Methods: On the basis of previous analyses of this problem, we determined that provider capability and opportunity were the main barriers to conducting and documenting serious illness conversations. We implemented the serious illness care program (SICP), a systematic multicomponent intervention that has shown potential for conducting and documenting ACP discussions in two oncology clinics. Our goal was to conduct at least 24 serious illness conversations over the implementation period, with documentation of at least 95% of all conversations. Results: The SICP was implemented in two outpatient medical oncology clinics. A total of 15 serious illness care conversations occurred and 14 (93%) of these conversations were documented in the EMR. Total rates of documentation increased between the preimplementation and implementation period (4.2%-5.4% for clinician A and 0%-7.3% for clinician B). Conclusion: Implementation of the SICP resulted in increased rates of documentation, but the target number of conversations was not met. Further improvement cycles are required to address barriers to conducting and documenting routine serious illness conversations.

RESUMO

To better understand cellular communication driving diverse behaviors, we need to uncover the molecular mechanisms of within-cell-type functional heterogeneity. While single-cell RNA sequencing (scRNAseq) has advanced our understanding of cell heterogeneity, linking individual cell phenotypes to transcriptomic data remains challenging. Here, we used a phenotypic cell sorting technique to ask whether phenotypically supervised scRNAseq analysis (pheno-scRNAseq) can provide more insight into heterogeneous cell behaviors than unsupervised scRNAseq. Using a simple 3D in vitro breast cancer (BRCA) model, we conducted pheno-scRNAseq on invasive and non-invasive cells and compared the results to phenotype-agnostic scRNAseq analysis. Pheno-scRNAseq identified unique and more selective differentially expressed genes than unsupervised scRNAseq analysis. Functional studies validated the utility of pheno-scRNAseq in understanding within-cell-type functional heterogeneity and revealed that migration phenotypes were coordinated with specific metabolic, proliferation, stress, and immune phenotypes. This approach lends new insight into the molecular systems underlying BRCA cell phenotypic heterogeneity.

RESUMO

BACKGROUND: Conventional MRI poorly distinguishes brain parenchyma microscopically invaded by high-grade gliomas (HGGs) from the normal brain. By contrast, quantitative histological MRI (hMRI) measures brain microstructure in terms of physical MR parameters influenced by histochemical tissue composition. We aimed to determine the relationship between hMRI parameters in the area surrounding the surgical cavity and the presence of HGG recurrence. METHODS: Patients were scanned after surgery with an hMRI multiparameter protocol that allowed for estimations of longitudinal relaxation rate (R1) = 1/T1, effective transverse relaxation rate (R2)*=1/T2*, magnetization transfer saturation (MTsat), and proton density. The initial perioperative zone (IPZ) was segmented on the postoperative MRI. Once recurrence appeared on conventional MRI, the area of relapsing disease was delineated (extension zone, EZ). Conventional MRI showing recurrence and hMRI were coregistered, allowing for the extraction of parameters R1, R2*, MTsat, and PD in 3 areas: the overlap area between the IPZ and EZ (OZ), the peritumoral brain zone, PBZ (PBZ = IPZ - OZ), and the area of recurrence (RZ = EZ - OZ). RESULTS: Thirty-one patients with HGG who underwent gross-total resection were enrolled. MTsat and R1 were the most strongly associated with tumor progression. MTsat was significantly lower in the OZ and RZ, compared to PBZ. R1 was significantly lower in RZ compared to PBZ. PD was significantly higher in OZ compared to PBZ, and R2* was higher in OZ compared to PBZ or RZ. These changes were detected 4 to 120 weeks before recurrence recognition on conventional MRI. CONCLUSIONS: HGG recurrence was associated with hMRI parameters' variation after initial surgery, weeks to months before overt recurrence.
