RESUMO
We sought to determine racial and ethnic differences in perceptions (quality of communication, expectations, and concerns) of germline or somatic DNA sequencing (genomic profiling). Patients with prostate, urothelial, or kidney cancer were surveyed using a questionnaire that assessed previous experience, beliefs, expectations, and concerns regarding genomic profiling. Descriptive statistics and chi-square tests were used to identify factors associated with patients' perceptions of genomic profiling. A total of 150 consecutive patients were enrolled. The majority were male (74%) with a mean age of 68 years old. Most patients underwent somatic testing (54%), 24% undertook germline testing, and 21% undertook both tests. Significant differences were found across racial and/or ethnicity concerning factors that could have influenced patients' decision to pursue genomic profiling, including ability to guide the type of treatment (White: 54.1% vs. other ethnic groups: 43.9%, p = 0.04) and potential to improve treatment response (White: 10.1% vs. other ethnic groups: 22.0%, p = 0.04). Other ethnic group of patients were more concerned about learning that the cancer was less treatable or aggressive (43.8% vs. 27.7%, p = 0.01) and anxious about what would be learnt from genomic profiling (34.4% vs. 21.3, p = 0.01) as compared to White patients. Our findings reinforce the importance of developing culturally tailored education to help patients participate actively in decisions about genomic profiling.
RESUMO
BACKGROUND: We explored changes in perceptions of cure among patients with genitourinary (GU) cancers starting Immune checkpoint inhibitors (ICIs) therapy. MATERIALS AND METHODS: This longitudinal study assessed patients before starting therapy and 3-months later with a questionnaire that included patient perceptions of ICIs and the Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety scale. General linear modeling was used to investigate changes in expectation of cure over time, and chi-square tests were used to determine the association between expectation of cure and perceptions of ICIs and anxiety. RESULTS: A total of 45 patients were recruited (73% male, 84% diagnosed with renal cell carcinoma). The proportion of patients who possessed an accurate expectation of cure increased over time (55.6%-66.7%, P = .001). An accurate expectation of cure was associated with lower rates of anxiety over time. Patients with inaccurate expectation of cure reported more severe side effects and worse self-reported ECOG score at the follow-up assessment (P = .04). CONCLUSION: We found that patients with GU metastatic cancer treated with ICI therapy have increasingly accurate expectations of cure over time. Accurate expectation of cure is associated with decreased anxiety. Further research is needed to fully explore this dynamic over time and help inform interventions that can help patients develop accurate expectations.

In the era of precision oncology, liquid biopsy techniques, especially the use of plasma circulating tumour DNA (ctDNA) analysis, represent a paradigm shift in the use of genomic biomarkers with considerable implications for clinical practice. Compared with tissue-based tumour DNA analysis, plasma ctDNA is more convenient to test, more readily accessible, faster to obtain and less invasive, minimizing procedure-related risks and offering the opportunity to perform serial monitoring. Additionally, genomic profiles of ctDNA have been shown to reflect tumour heterogeneity, which has important implications for the identification of resistant clones and selection of targeted therapy well before clinical and radiographic changes occur. Moreover, plasma ctDNA testing can also be applied to cancer screening, risk stratification and quantification of minimal residual disease. These features provide an unprecedented opportunity for early treatment of patients, improving the chances of treatment success.

OBJECTIVE: Rare cancers are a heterogeneous group of conditions that can be associated with emotional and physical impairments. In view of the dearth of research in this area, we investigated the quality of life and prevalence of distress in a cohort of patients diagnosed with a rare cancer, classified by the RARECARE definition. METHODS: A cohort of rare cancer patients, treated in a Brazilian public cancer center, was assessed for distress (Distress Thermometer), anxiety/depression (Hospital Anxiety and Depression Scale), and quality of life (Functional Assessment of Cancer Therapy-General Version). Descriptive statistics were generated, and multivariate analyses were used to identify factors associated with distress, anxiety/depression, and quality of life. RESULTS: A total of 137 patients (52.6% male, mean age of 50 years; range 18-90) were identified. Nearly half (49.6%) of patients reported high levels of distress, with 19.7% endorsing anxiety and 15.3% depression. In multivariate analysis, demographic and clinical variables associated with worse psychosocial outcomes included younger age (P < 0.05), female gender (P < 0.01), advanced disease stage (P < 0.01), and engagement in active therapy (P < 0.05). CONCLUSIONS: Patients diagnosed with rare cancer reported poorer psychosocial outcomes and impaired quality of life when compared to the general population of cancer patients. Certain demographic groups (eg, women and younger patients) may benefit from targeted psychosocial interventions.
