RESUMO

Quantitative evaluation of tissue images is crucial for computational pathology (CPath) tasks, requiring the objective characterization of histopathological entities from whole-slide images (WSIs). The high resolution of WSIs and the variability of morphological features present significant challenges, complicating the large-scale annotation of data for high-performance applications. To address this challenge, current efforts have proposed the use of pretrained image encoders through transfer learning from natural image datasets or self-supervised learning on publicly available histopathology datasets, but have not been extensively developed and evaluated across diverse tissue types at scale. We introduce UNI, a general-purpose self-supervised model for pathology, pretrained using more than 100 million images from over 100,000 diagnostic H&E-stained WSIs (>77 TB of data) across 20 major tissue types. The model was evaluated on 34 representative CPath tasks of varying diagnostic difficulty. In addition to outperforming previous state-of-the-art models, we demonstrate new modeling capabilities in CPath such as resolution-agnostic tissue classification, slide classification using few-shot class prototypes, and disease subtyping generalization in classifying up to 108 cancer types in the OncoTree classification system. UNI advances unsupervised representation learning at scale in CPath in terms of both pretraining data and downstream evaluation, enabling data-efficient artificial intelligence models that can generalize and transfer to a wide range of diagnostically challenging tasks and clinical workflows in anatomic pathology.

RESUMO

C-X-C motif chemokine receptor 2 (CXCR2) has a role in tumor progression, lineage plasticity, and reduction of immune checkpoint inhibitor efficacy. Preclinical evidence suggests potential benefit of CXCR2 inhibition in multiple solid tumors. In this phase 2 study (NCT03473925), adults with previously treated advanced or metastatic castration-resistant prostate cancer (CRPC), microsatellite-stable colorectal cancer (MSS CRC), or non-small-cell lung cancer (NSCLC) were randomized 1:1 to the CXCR2 antagonist navarixin 30 or 100 mg orally once daily plus pembrolizumab 200 mg intravenously every 3 weeks up to 35 cycles. Primary endpoints were investigator-assessed objective response rate (RECIST v1.1) and safety. Of 105 patients (CRPC, n=40; MSS CRC, n=40; NSCLC, n=25), 3 had a partial response (2 CRPC, 1 MSS CRC) for ORRs of 5%, 2.5%, and 0%, respectively. Median progression-free survival was 1.8-2.4 months without evidence of a dose-response relationship, and the study was closed at a prespecified interim analysis for lack of efficacy. Dose-limiting toxicities occurred in 2/48 patients (4%) receiving navarixin 30 mg and 3/48 (6%) receiving navarixin 100 mg; events included grade 4 neutropenia and grade 3 transaminase elevation, hepatitis, and pneumonitis. Treatment-related adverse events occurred in 70/105 patients (67%) and led to treatment discontinuation in 7/105 (7%). Maximal reductions from baseline in absolute neutrophil count were 44.5%-48.2% (cycle 1) and 37.5%-44.2% (cycle 2) and occurred within 6-12 hours postdose in both groups. Navarixin plus pembrolizumab did not demonstrate sufficient efficacy in this study. Safety and tolerability of the combination were manageable.

RESUMO

Family health history (FHH) is an evidence-based genomics tool used in cancer prevention and education. Chinese Americans, the largest Asian American group, face unique barriers in FHH collection and communication. This study aimed to evaluate the efficacy of culturally and linguistically appropriate community health worker (CHW)-delivered FHH-based breast cancer (BC) education and services to Chinese Americans. A total of 1129 Chinese Americans received FHH-based BC education and service delivered by our trained Chinese American CHWs. Participants responded to evaluation surveys before, immediately after, and 3 months after the education and service. Participating Chinese Americans showed significant increases in rates of collecting FHH of BC, discussing FHH of BC with family members, informing their primary care physicians of their FHH of BC, and discussing their FHH of BC with their primary care physicians at 3 months post-education and service compared to the baseline data (all Ps < 0.01). Attitudes, intention, and self-efficacy related to FHH of BC communication and collection and FHH of BC knowledge were improved both immediately after and 3 months after the delivery of the education and services (all Ps < 0.01). Within 3 months, ~ 14.3% of participants who had a high risk of BC based on FHH reported visiting geneticists for genetic evaluation. Our Chinese American CHW-delivered FHH-based BC education and services showed initial success in increasing knowledge, collection and communication of BC-related FHH, and genetic service utilization among Chinese American participants. This study can serve as a starting point for conducting more robust studies, such as randomized controlled trials, in the future.

RESUMO

PURPOSE: The assumption that patient-provider communication may mediate patients' sense of control over cancer to affect health outcomes has limited evidence. This study examines whether patient-perceived cancer care communication quality (PPCQ) mediates stress appraisal and coping behavior, affecting physical functioning across different racial groups. METHODS: Two hundred and twenty Chinese American and 216 non-Hispanic White (NHW) women (ages 28-80) with stage 0-III breast cancer, 1-5 years post-diagnosis, and without recurrence, enrolled and completed a cross-sectional telephone survey. Physical functioning was measured by the NIH-PROMIS short form. Validated measures of PPCQ, patients' evaluation of their socioeconomic well-being, stress appraisal (perceived severity and control), use of coping strategies, treatment-related symptoms, and comorbidities were also assessed. Path analyses were used to examine the mediation for each racial group. RESULTS: Regardless of race, treatment-related symptoms, comorbidities, and socioeconomic well-being were all directly related to physical functioning (p < 0.05). The impact of PPCQ on physical functioning was mediated by perceived control in the Chinese American group (p < 0.05), but not in the NHW group. Perceived severity and coping were not mediators of physical functioning in either group. CONCLUSIONS: The mediational pathway from PPCQ to perceived control to physical functioning in Chinese American survivors may be partially explained by their lower socioeconomic well-being and culturally valued conformity to physicians as a medical authority. These sociocultural dynamics reinforce the importance of cancer care communication. For NHW survivors, the impact of treatment-related symptoms and socioeconomic well-being on physical functioning outweighed their PPCQ and perceived control.

RESUMO

INTRODUCTION: Initial treatment for nonmetastatic breast cancer is resection or neoadjuvant systemic therapy, depending on tumor biology and patient factors. Delays in treatment have been shown to impact survival and quality of life. Little has been published on the performance of safety-net hospitals in delivering timely care for all patients. METHODS: We conducted a retrospective study of patients with invasive ductal or lobular breast cancer, diagnosed and treated between 2009 and 2019 at an academic, safety-net hospital. Time to treatment initiation was calculated for all patients. Consistent with a recently published Committee on Cancer timeliness metric, a treatment delay was defined as time from tissue diagnosis to treatment of greater than 60 days. RESULTS: A total of 799 eligible women with stage 1-3 breast cancer met study criteria. Median age was 60 years, 55.7% were non-white, 35.5% were non-English-speaking, 18.9% were Hispanic, and 49.4% were Medicaid/uninsured. Median time to treatment was 41 days (IQR 27-56 days), while 81.1% of patients initiated treatment within 60 days. The frequency of treatment delays did not vary by race, ethnicity, insurance, or language. Diagnosis year was inversely associated with the occurrence of a treatment delay (OR: 0.944, 95% CI 0.893-0.997, p value: 0.039). CONCLUSION: At our institution, race, ethnicity, insurance, and language were not associated with treatment delay. Additional research is needed to determine how our safety-net hospital delivered timely care to all patients with breast cancer, as reducing delays in care may be one mechanism by which health systems can mitigate disparities in the treatment of breast cancer.

RESUMO

Tissue phenotyping is a fundamental computational pathology (CPath) task in learning objective characterizations of histopathologic biomarkers in anatomic pathology. However, whole-slide imaging (WSI) poses a complex computer vision problem in which the large-scale image resolutions of WSIs and the enormous diversity of morphological phenotypes preclude large-scale data annotation. Current efforts have proposed using pretrained image encoders with either transfer learning from natural image datasets or self-supervised pretraining on publicly-available histopathology datasets, but have not been extensively developed and evaluated across diverse tissue types at scale. We introduce UNI, a general-purpose self-supervised model for pathology, pretrained using over 100 million tissue patches from over 100,000 diagnostic haematoxylin and eosin-stained WSIs across 20 major tissue types, and evaluated on 33 representative CPath clinical tasks in CPath of varying diagnostic difficulties. In addition to outperforming previous state-of-the-art models, we demonstrate new modeling capabilities in CPath such as resolution-agnostic tissue classification, slide classification using few-shot class prototypes, and disease subtyping generalization in classifying up to 108 cancer types in the OncoTree code classification system. UNI advances unsupervised representation learning at scale in CPath in terms of both pretraining data and downstream evaluation, enabling data-efficient AI models that can generalize and transfer to a gamut of diagnostically-challenging tasks and clinical workflows in anatomic pathology.

RESUMO

PROBLEM IDENTIFICATION: This meta-analysis evaluated the effects of various types of educational interventions on increasing breast cancer screening uptake among Asian American women. LITERATURE SEARCH: Web of Science, MEDLINE®, PubMed®, and Cochrane Library were searched for randomized controlled trials published from 2010 to 2020 of interventions developed to promote mammography uptake among Asian American women. DATA EVALUATION: A random-effects model was used to estimate pooled effect sizes using relative risk measures. A funnel plot was used to assess publication bias. SYNTHESIS: Seven studies were included in this review. Educational interventions identified were primarily culturally sensitive approaches combined with access-enhancing, individually tailored, or group-based approaches. The interventions were effective at increasing the receipt of mammography. IMPLICATIONS FOR NURSING: This review provides insight into the importance of combining other approaches with educational interventions to increase their effectiveness for Asian American women. Future interventions can incorporate various approaches to enhance the ability of Asian American women to overcome barriers to breast cancer screening.

RESUMO

PURPOSE: In this first-in-human, Phase 1, open-label, multicenter study, we evaluated JNJ-64619178, a selective and potent PRMT5 inhibitor, in patients with advanced malignant solid tumors or non-Hodgkin lymphomas (NHL). The primary objective was to evaluate the safety and to identify a recommended Phase 2 dose (RP2D) of JNJ-64619178. PATIENTS AND METHODS: Adult patients with treatment-refractory advanced solid tumors or NHL and measurable disease received escalating doses of JNJ-64619178 following two schedules (Schedule A: 14 days on/7 days off; Schedule B: every day on a 21-day cycle). Safety, pharmacokinetics (PK), pharmacodynamics (PD), and clinical activity were evaluated. RESULTS: Ninety patients received JNJ-64619178. Thrombocytopenia was identified as the only dose-limiting toxicity. JNJ-64619178 showed dose-proportional PK and robust target engagement, as measured by plasma symmetric dimethylarginine, across all dose levels. The objective response rate was 5.6% (5 of 90). Patients with adenoid cystic carcinoma (ACC) had an ORR of 11.5% (3 of 26) and a median progression-free survival of 19.1 months. CONCLUSIONS: JNJ-64619178 demonstrated manageable dose-dependent toxicity and preliminary evidence of antitumor activity in ACC and other tumor types. Plasma exposure was dose dependent, and target inhibition was maintained with intermittent and continuous dosing. On the basis of safety, clinical activity, PK, and PD findings, two provisional RP2Ds were selected: 1.5 mg intermittently and 1.0 mg once daily. Aside from ACC, clinical benefit was limited, and biomarkers to enrich for responsiveness to PRMT5 inhibition will be needed for further development.

RESUMO

AZD5153, a reversible, bivalent inhibitor of the bromodomain and extraterminal family protein BRD4, has preclinical activity in multiple tumors. This first-in-human, phase I study investigated AZD5153 alone or with olaparib in patients with relapsed/refractory solid tumors or lymphoma. Adults with relapsed tumors intolerant of, or refractory to, prior therapies received escalating doses of oral AZD5153 once daily or twice daily continuously (21-day cycles), or AZD5153 once daily/twice daily continuously or intermittently plus olaparib 300 mg twice daily, until disease progression or unacceptable toxicity. Between June 30, 2017 and April 19, 2021, 34 patients received monotherapy and 15 received combination therapy. Dose-limiting toxicities were thrombocytopenia/platelet count decreased (n = 4/n = 2) and diarrhea (n = 1). The recommended phase II doses (RP2D) were AZD5153 30 mg once daily or 15 mg twice daily (monotherapy) and 10 mg once daily (intermittent schedule) with olaparib. With AZD5153 monotherapy, common treatment-emergent adverse events (TEAE) included fatigue (38.2%), thrombocytopenia, and diarrhea (each 32.4%); common grade ≥ 3 TEAEs were thrombocytopenia (14.7%) and anemia (8.8%). With the combination, common TEAEs included nausea (66.7%) and fatigue (53.3%); the most common grade ≥ 3 TEAE was thrombocytopenia (26.7%). AZD5153 had dose-dependent pharmacokinetics, with minimal accumulation, and demonstrated dose-dependent modulation of peripheral biomarkers, including upregulation of HEXIM1. One patient with metastatic pancreatic cancer receiving combination treatment had a partial response lasting 4.2 months. These results show AZD5153 was tolerable as monotherapy and in combination at the RP2Ds; common toxicities were fatigue, hematologic AEs, and gastrointestinal AEs. Strong evidence of peripheral target engagement was observed.

RESUMO

OBJECTIVE: Evaluate the impact of a 6-month structured mentorship program between women premedical student mentees paired with women medical students and surgical residents on mentees' interests and perceptions of surgical careers. DESIGN: Prospective qualitative and quantitative study. SETTING: This study took place at the Boston University School of Medicine, a single institution tertiary care hospital. PARTICIPANTS: Self-identified women premedical students at Boston University were eligible for inclusion in this program (n=90). Participants were recruited and grouped with self-identified women medical student (n=52) and resident (n=19) mentors. Participants were provided with a monthly curriculum to guide discussions. Mentees completed pre- and postprogram surveys with 5-point Likert scale questions regarding interest and exposure to surgery, role models and mentorship, and effect of COVID-19 on their career interests. Pre- and postprogram responses were compared using a Wilcoxon rank sum test. RESULTS: Of the 90 mentees, 63 (70%) completed preprogram surveys, and 53 (59%) completed postprogram surveys. Survey respondents indicated statistically significant increased exposure to positive role models (preprogram mean 3.15, postprogram mean 4.06, p=0.0003), increased exposure to women role models (preprogram 2.30, postprogram 3.79, p<0.0001), increased access to dedicated mentors (preprogram 2.11, postprogram 3.75, p<0.0001), and increased availability of support persons to answer their questions and concerns about careers in surgery (preprogram 3.03, postprogram 3.85, p=0.001). There was also a statistically significant increase in the reported effect that exposure to gender-concordant role models in surgery had on participants' decisions to consider a surgical career (preprogram 3.58, postprogram 4.23, p=0.001). CONCLUSION: This 6-month structured mentorship program for undergraduate premedical students increased mentees' exposure to positive women role models and mentors, and increased mentee's interest in pursuing a surgical career. This emphasizes the need for structured gender-concordant mentorship programs early in women's careers to encourage pursuit of surgical careers in an otherwise men-dominated field.

RESUMO

Surufatinib, is a potent inhibitor of vascular endothelial growth factor receptors 1-3; fibroblast growth factor receptor-1; colony-stimulating factor 1 receptor. This Phase 1/1b escalation/expansion study in US patients with solid tumors evaluated 5 once daily (QD) surufatinib doses (3 + 3 design) to identify maximum tolerated dose (MTD), recommended Phase 2 dose (RP2D), and evaluate safety and efficacy at the RP2D in 4 disease-specific expansion cohorts including pancreatic neuroendocrine tumors [pNET] and extrapancreatic NETs [epNET]. MTD and RP2D were 300 mg QD (escalation [n = 35]); 5 patients (15.6%) (Dose Limiting Toxicity [DLT] Evaluable Set [n = 32]) had DLTs. Pharmacokinetics were dose proportional. Estimated progression-free survival (PFS) rates at 11 months were 57.4% (95% confidence interval [CI]: 28.7, 78.2) and 51.1% (95% CI: 12.8, 80.3) for pNET and epNET expansion cohorts, respectively. Median PFS was 15.2 (95% CI: 5.2, not evaluable) and 11.5 (95% CI: 6.5,11.5) months. Response rates were 18.8% and 6.3%. The most frequent treatment-emergent adverse events (both cohorts) were fatigue (46.9%), hypertension (43.8%), proteinuria (37.5%), diarrhea (34.4%). Pharmacokinetics, safety, and antitumor efficacy of 300 mg QD oral surufatinib in US patients with pNETs and epNETs are consistent with previously reported studies in China and may support applicability of earlier surufatinib studies in US patients. Clinical trial registration: Clinicaltrials.gov NCT02549937.

RESUMO

AIM: We evaluated MK-8353 (small molecule inhibitor of extracellular signal-regulated kinase 1/2) plus selumetinib (mitogen-activated extracellular signal-regulated kinase 1/2 inhibitor) in patients with advanced solid tumors. METHODS: This phase 1b, open-label, dose-escalation study (NCT03745989) enrolled adults with histologically/cytologically documented, locally advanced/metastatic solid tumors. MK-8353/selumetinib dose combinations were intended to be investigated in sequence: 50/25, 100/50, 150/75, 200/75, 200/100, and 250/100. Each agent was administered orally BID 4 days on/3 days off in repeating cycles every 21 days. Primary objectives were safety and tolerability and to establish preliminary recommended phase 2 doses for combination therapy. RESULTS: Thirty patients were enrolled. Median (range) age was 61.5 (26-78) years and 93% had received previous cancer therapy. Among 28 patients in the dose-limiting toxicities [DLT]-evaluable population, 8 experienced DLTs: 1/11 (9%) in the MK-8353/selumetinib 100/50-mg dose level experienced a grade 3 DLT (urticaria), and 7/14 (50%) in the 150/75-mg dose level experienced grade 2/3 DLTs (n = 2 each of blurred vision, retinal detachment, vomiting; n = 1 each of diarrhea, macular edema, nausea, retinopathy). The DLT rate in the latter dose level exceeded the prespecified target DLT rate (~30%). Twenty-six patients (87%) experienced treatment-related adverse events (grade 3, 30%; no grade 4/5), most commonly diarrhea (67%), nausea (37%), and acneiform dermatitis (33%). Three patients (10%) experienced treatment-related adverse events leading to treatment discontinuation. Best response was stable disease in 14 patients (n = 10 with MK-8353/selumetinib 150/75 mg). CONCLUSION: MK-8353/selumetinib 50/25 mg and 100/50 mg had acceptable safety and tolerability, whereas 150/75 mg was not tolerable. No responses were observed.

RESUMO

BACKGROUND: AZD2811 is a potent, selective Aurora kinase B inhibitor. We report the dose-escalation phase of a first-in-human study assessing nanoparticle-encapsulated AZD2811 in advanced solid tumours. METHODS: AZD2811 was administered in 12 dose-escalation cohorts (2-h intravenous infusion; 15‒600 mg; 21-/28-day cycles) with granulocyte colony-stimulating factor (G-CSF) at higher doses. The primary objective was determining safety and maximum tolerated/recommended phase 2 dose (RP2D). RESULTS: Fifty-one patients received AZD2811. Drug exposure was sustained for several days post-dose. The most common AZD2811-related adverse events (AEs) were fatigue (27.3%) at ≤200 mg/cycle and neutropenia (37.9%) at ≥400 mg/cycle. Five patients had dose-limiting toxicities: grade (G)4 decreased neutrophil count (n = 1, 200 mg; Days 1, 4; 28-day cycle); G4 decreased neutrophil count and G3 stomatitis (n = 1 each, both 400 mg; Day 1; 21-day cycle); G3 febrile neutropenia and G3 fatigue (n = 1 each, both 600 mg; Day 1; 21-day cycle +G-CSF). RP2D was 500 mg; Day 1; 21-day cycle with G-CSF on Day 8. Neutropenia/neutrophil count decrease were on-target AEs. Best overall responses were partial response (n = 1, 2.0%) and stable disease (n = 23, 45.1%). CONCLUSIONS: At RP2D, AZD2811 was tolerable with G-CSF support. Neutropenia was a pharmacodynamic biomarker. CLINICAL TRIAL REGISTRATION: NCT02579226.

RESUMO

Breast cancer is the most commonly diagnosed cancer among Chinese American women. Knowing the BRCA1 and BRCA2 (BRCA1/2) gene mutation status can improve breast cancer patients' health outcomes by guiding targeted treatment towards preventing breast cancer recurrence and other BRCA-related cancers. Nevertheless, it is unclear if there is a disparity in knowledge and use of BRCA testing among Chinese American breast cancer patients. This cross-sectional study investigated the possible presence of differences in the knowledge and the use of BRCA testing between Chinese American and Non-Hispanic White (NHW) breast cancer patients. We surveyed 45 Chinese American and 48 NHW adult breast cancer patients who had been diagnosed with breast cancer within the previous two years through telephone interviews. The results showed that race was not statistically related to the use of BRCA testing. BRCA testing utilization was associated with family history (p < 0.05) and age (p < 0.05). However, Chinese American participants' understanding of BRCA testing was significantly lower than that of NHW participants (p = 0.030). Our findings suggest that a disparity exists in BRCA testing knowledge between Chinese American and NHW breast cancer patients. Genetic education and counseling are needed to improve BRCA testing knowledge and uptake among Chinese American breast cancer patients.

RESUMO

INTRODUCTION: Quality of life (QoL) of endocrine surgery patients is an important patient outcome but the role of social determinants of health (SDH) on preoperative QoL is understudied. METHODS: This study used preoperative data of 233 endocrine surgery patients participating in a longitudinal QoL study to examine the influence of SDH (patient-level and environmental) on preoperative QoL. Patient-level SDH was assessed with structured survey questions and environmental SDH with the Social Vulnerability Index. Multiple domains of QoL were assessed with the Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29). RESULTS: The average age of the sample was 52.9 y and 76.8% were female, 10% were Hispanic, 55.8% were White, 32.6% were Black, 6.9% were Other, and 4.7% were Asian. Patients with patient-level SDH were more likely to have worse preoperative QoL in multiple PROMIS domains. Patients who lived in the most socially vulnerable areas had the same or better QoL scores in the PROMIS-29 domains than those living in less vulnerable areas. Minority race patients were more likely to have patient-level SDH and to live in the most vulnerable areas. CONCLUSIONS: This study is the first to our knowledge to examine the role of patient-level and environmental SDH on preoperative QoL among endocrine surgery patients. The results identified specific patient-level factors that could be used as the basis for interventions aimed to improve patients' QoL. Future studies that evaluate the role of preoperative SDH on long-term QoL and clinical outcomes would further enhance our understanding of the impact of SDH on patient wellbeing.

RESUMO

BACKGROUND: Extant literature on the relationship between cancer fatalism and psychological distress among Chinese American breast cancer survivors has been mixed, and few studies have examined potential mediators of this relationship. The current study examined how cancer fatalism is associated with psychological distress by investigating perceived personal control and fear of cancer recurrence as mediators, and acculturation as a moderator of these relationships. METHOD: A total of 220 Chinese American women diagnosed with stage 0-III breast cancer were recruited from California cancer registries and completed a telephone survey. The measurement of cancer fatalism examined one's view of health as a result of destiny. Validated measures of psychological distress (i.e., depressive and anxiety symptoms), fear of cancer recurrence, and perceived personal control were used. Acculturation was defined by English proficiency, preferred interview language, and number of years lived in the USA. RESULTS: Higher cancer fatalism was directly associated with greater depressive and anxiety symptoms after controlling for covariates. This association was also mediated by higher fear of cancer recurrence, but not by perceived control. The mediation was not moderated by acculturation. CONCLUSION: Our findings suggest that Chinese American breast cancer survivors' fatalistic beliefs may exacerbate fear of cancer recurrence, and, in turn, depressive and anxiety symptoms. Fear of recurrence was more salient than perceived control in their associations with psychological distress among Chinese American cancer survivors. Future intervention research may adopt cognitive approaches to alter Chinese survivors' fatalistic views of health outcomes to reduce their psychological distress.

RESUMO

Chinese immigrant cancer patients report suboptimal patient-provider communication, which increases the likelihood of decisional conflict and unsatisfactory treatment decision-making (TDM) outcomes (e.g., low satisfaction and perceived control over cancer care). This cross-sectional study explored whether (1) communication and decisional conflict factors associated with TDM outcomes differed between Chinese immigrant and non-Hispanic White breast cancer patients, and (2) the association between patient-provider communication and the outcomes were mediated by TDM factors, regardless of race. Ninety-eight breast cancer patients, diagnosed at stage I-III participated in cross-sectional survey interviews. TDM outcomes and possible predictors of the outcomes (e.g., patient-provider communication, decisional conflict, preference for who makes the treatment decision) were assessed. Linear regression and mediational testing were performed to examine associations among variables of interest. Of the 98, 85 were included for analysis. Chinese patients with limited English proficiency (n = 37) had poorer patient-provider communication, higher decisional conflict, and preferred providers to make decisions than non-Hispanic White patients (n = 48; all p < .05). They also had lower satisfaction with their TDM process after controlling for predictors (e.g., patient-provider communication) (p < .001). There were no significant racial differences in perceived control, controlling for covariates. Regardless of race, patients who reported quality patient-provider communication reported less decisional conflict. These patients also reported increased satisfaction and perceived control. The disparities Chinese immigrant cancer patients experienced in the TDM process may be related to their cultural communication style with providers. Facilitating Chinese patients' communication and partnership with providers may reduce decisional conflicts and increase their TDM outcomes.

RESUMO

PURPOSE: Few studies have examined experiences of stigma and factors associated with symptoms among cervical cancer survivors from diverse racial and ethnic backgrounds. We investigated survivorship experiences and patient-reported outcomes in the SPADE symptom cluster (sleep disturbance, pain interference, anxiety, depression, and energy/fatigue) among Black, Latina, and Chinese American women diagnosed with cervical cancer. METHODS: In two phases of research with cervical cancer survivors, we collected qualitative data through individual interviews (N=12; recruited through community referrals) and quantitative data from an observational cohort study (N=91; recruited through 4 national cancer registries). We coded interview transcripts to describe the survivors' experiences. We then evaluated associations between social support, spirituality, and SPADE symptom cluster domains using linear regression models. RESULTS: Qualitative analysis yielded four themes: perceptions of stigma, empowerment, physical and psychological effects, and social support. These concepts revolved around internal and external stigmas, emotional responses, strengthened faith, and different social support types. Quantitative analyses indicated that greater spirituality was associated with lower symptom burden on all five SPADE domains (p<0.01). We observed nuanced associations between specific types of social support and SPADE domains. CONCLUSIONS: The survivorship experiences of Black, Latina, and Chinese American women with cervical cancer are negatively influenced by perceptions of stigma. Higher scores on spirituality and varied types of social support were significantly associated with fewer symptoms in the SPADE symptom cluster. IMPLICATIONS FOR CANCER SURVIVORS: Results suggest targets for future interventions to reduce symptom burden among women diagnosed with cervical cancer by leveraging spirituality and social support.

RESUMO

BACKGROUND: Frailty predicts adverse perioperative outcomes and increased mortality in patients having vascular surgery. Frailty assessment is a potential tool to inform resource allocation, and shared decision-making about vascular surgery in the resource constrained COVID-19 pandemic environment. This cohort study describes the prevalence of frailty in patients having vascular surgery and the association between frailty, mortality and perioperative outcomes. METHODS: The COVID-19 Vascular Service in Australia (COVER-AU) prospective cohort study evaluates 30-day and six-month outcomes for consecutive patients having vascular surgery in 11 Australian vascular units, March-July 2020. The primary outcome was mortality, with secondary outcomes procedure-related outcomes and hospital utilization. Frailty was assessed using the nine-point visual Clinical Frailty Score, scores of 5 or more considered frail. RESULTS: Of the 917 patients enrolled, 203 were frail (22.1%). The 30 day and 6 month mortality was 2.0% (n = 20) and 5.9% (n = 35) respectively with no significant difference between frail and non-frail patients (OR 1.68, 95%CI 0.79-3.54). However, frail patients stayed longer in hospital, had more perioperative complications, and were more likely to be readmitted or have a reoperation when compared to non-frail patients. At 6 months, frail patients had twice the odds of major amputation compared to non-frail patients, after adjustment (OR 2.01; 95% CI 1.17-3.78), driven by a high rate of amputation during the period of reduced surgical activity. CONCLUSION: Our findings highlight that older, frail patients, experience potentially preventable adverse outcomes and there is a need for targeted interventions to optimize care, especially in times of healthcare stress.

RESUMO

Sitravatinib (MGCD516), a spectrum-selective receptor tyrosine kinase inhibitor targeting TAM (TYRO3, AXL, MERTK) and split kinase family receptors, has demonstrated preclinical anti-tumor activity and modulation of tumor microenvironment. This first-in-human phase 1/1b study included sitravatinib dose exploration and anti-tumor activity evaluation in selected patients with advanced solid tumors. Primary objectives included assessment of safety, pharmacokinetics and clinical activity of sitravatinib. Secondary objectives included identifying doses for further investigation and exploring molecular markers for patient selection. In phase 1, 32 patients received 10-200 mg, while phase 1b dose expansion comprised 161 patients (150 mg n = 99, 120 mg n = 62). Maximum tolerated dose was determined as 150 mg daily. Dose-limiting toxicity was reported in 4/28 evaluable phase 1 patients (three at 200 mg, one at 80 mg). In phase 1b, 120 mg was defined as the recommended dose due to tolerability. Treatment-related adverse events (TRAEs) were experienced by 174/193 patients (90.2%); grade ≥ 3 TRAEs in 103 patients (53.4%). Most common TRAEs were diarrhea, fatigue, hypertension and nausea; TRAEs led to treatment discontinuation in 26 patients (13.5%) and death in one patient. Sitravatinib was steadily absorbed and declined from plasma with a terminal elimination half-life of 42.1-51.5 h following oral administration. Overall objective response rate was 11.8% in phase 1b, 13.2% in patients with non-small cell lung cancer (NSCLC) and 4.2% in patients with NSCLC with prior checkpoint inhibitor experience. Sitravatinib demonstrated manageable safety and modest clinical activity in solid tumors. NCT02219711 (first posted August 14, 2014).
