RESUMO

Despite racial disparities in breast cancer mortality, Black women remain underrepresented in clinical trials. In this mixed methods research, 48 Black women were engaged via focus group discussions and in-depth interviews to better understand the lived experience of women with breast cancer. The results of this qualitative study informed the development of a subsequent online survey to identify barriers, motivators, and other factors that influence decision-making by Black women diagnosed with breast cancer when considering clinical trial participation. Among the 257 Black survey participants, most (95%) were aware of clinical trials; of those, most viewed them as lifesaving (81%) and/or benefiting others (90%). Negative perceptions such as serious side effects (58%), not receiving real treatment (52%), or risk of potential harm (62%) were indicated. Barriers included financial expenses (49%), concerns that their condition could be made worse (29%), that they would receive a placebo (28%), or that treatment was unapproved (28%). Participants were more likely than their health care providers (HCPs) to initiate discussions of clinical trials (53% versus 33%), and 29% of participants indicated a need for more information about risks and benefits, even after having those conversations. The most trustworthy sources of information on clinical trials were HCPs (66%) and breast cancer support groups (64%). These results suggest that trusted communities are key for providing education on clinical trials. However, there is also a need for HCPs to proactively discuss clinical trials with patients to ensure that they are adequately informed about all aspects of participation.

RESUMO

PURPOSE: Numerous experimental and targeted therapies are under investigation for patients with cholangiocarcinoma (CCA). Objective health-related quality of life (HRQoL) data for patients receiving these therapies are limited. METHODS: Patients engaged in the Cholangiocarcinoma Foundation completed two validated HRQoL surveys: Functional Assessment of Cancer Therapy (FACT)-Hepatobiliary and COmprehensive Score for financial Toxicity (COST). RESULTS: Two hundred eight patients were included. Seventy-five percent had intrahepatic CCA and 57% underwent resection, of which 48% had disease recurrence. Twenty-two percent enrolled in a clinical trial and 80% underwent molecular profiling, of which 29% received targeted therapy. While patients enrolled in a clinical trial or received targeted therapy reported similar HRQoL compared to those who did not, they reported higher financial toxicity (p = 0.05 and p = 0.01, respectively). CONCLUSION: Enrollment in a clinical trial or receipt of targeted therapy do not affect a patient's physical, emotional, social, or functional well-being. However, patients report higher financial burden. These therapies are mainly offered in the advanced setting after significant financial strain has been endured and are often only available at large academic centers, creating a physical barrier to access. These findings underscore the need to increase availability and eliminate physical and financial barriers that threaten access and utilization of personalized and progressive therapies.

RESUMO

The development of JFH1 based intergenotypic recombinants that exploit the unique replication characteristics of JFH1 has made it possible to study infectious hepatitis C virus (HCV) encoding the structural genes of additional HCV genotypes. To facilitate the study of 1b structural proteins, we aimed to develop a robust 1b/2a chimera encoding a humanized Renilla luciferase reporter gene (1b/2a hRluc). The unadapted genome replicated efficiently but produced very low titers of infectious virus. Adaptation by continuous passage over a novel Huh-7 Lunet clone improved viral titers approximately 100-fold but caused an unexpected decline in luciferase activity, limiting the utility of the reporter-containing virus. Genotypic analysis revealed 17 adenosine to guanosine (A to G) nucleotide mutations in the luciferase gene and two potential adaptive mutations. To overcome the problems of low viral titers and editing of the luciferase gene during viral adaptation, six adaptive mutations previously identified in a non-reporter 1b/2a HCV genome were introduced into the 1b/2a hRluc genome. This resulted in the immediate production of high-titer viral stocks (approximately 1000-fold greater than the parental virus) that could efficiently infect naïve cells and generate robust luciferase signals. The improved sensitivity of the luciferase reporter also facilitated time of addition studies validating the utility of this system for characterizing the early steps of HCV infection. Thus, the development of the 1b/2a hRluc reporter virus described here provides a versatile tool for discovery of inhibitors targeting the early steps of the viral life cycle and genotype 1b structural genes.
