More Help from Friends and Family? Trends in Determinants of Surrogate Health Information-Seeking

Friends and family members often choose to seek health information for a loved one, rather than all information-seeking being carried out by the patient for themselves. Despite the popularity of this proxy for health information-seeking behavior (PHISB), there is a lack of more current data on PHISB, as well as on changes in PHISB. We analyzed health information-seeking based on data from the two available waves of the HINTS Germany study (2018/19: N = 2.147;2020: N = 1.865). HINTS Germany is a data set mapping health information behaviors in the German population, closely linked to the well-established U.S. HINTS. The results show an increase in health information-seeking of 6.2% (p < .001), between the first wave (36%; n = 772) and the second wave (42%; n = 778). A bivariate analysis followed by a hierarchical logit model yielded similar significant determinants for PHISB. Gender, being in a stable relationship, and different information sources were all found to be significant for health information-seeking. The results show the need for tailored population information for proxies, to improve their respective communication with patients.

Molecular mechanism of type ib MET inhibitors and their potential for CNS tumors

The emergence of targeted therapies for MET exon 14 (METex14) skipping mutations has significantly changed the treatment landscape for NSCLC and other solid tumors. The skipping of METex14 results in activating the MET-HGF pathway and promoting tumor cell proliferation, migration, and preventing apoptosis. Type Ib MET inhibitors, designed to selectively target the "DFG-in" conformation of MET, characteristically bind to the ATP-binding pocket of MET in a U-shaped conformation, extending into the solvent-accessible region and interact strongly with residue Y1230 through π-π interactions, have shown remarkable efficacy in treating METex14-altered NSCLC, including cases with brain metastases (BMs). Notably, vebreltinib and capmatinib have demonstrated superior blood-brain barrier (BBB) permeability in both computational and experimental models, highlighting their potential for treating the central nervous system (CNS) metastases. P-glycoprotein (P-gp) is highly expressed in the BBB, which limits the brain uptake of many highly lipophilic drugs. Despite challenges posed by P-gp mediated efflux, vebreltinib has emerged as a promising candidate for CNS treatment due to its favorable pharmacokinetic profile and minimal susceptibility to P-gp efflux. This study underscores the importance of molecular dynamics simulations in predicting drug efficacy and BBB penetration, providing valuable insights for the development of CNS-targeted metastases therapies.

Development and effectiveness evaluation of an interactive e-learning environment to enhance digital health literacy in cancer patients: study protocol for a randomized controlled trial

Background

The Internet allows cancer patients to access information about their disease at any time. However, the quality of online information varies widely and is often inaccurate or does not provide all the details patients need to make informed decisions. Additionally, patients' often limited ability to find and evaluate cancer-related online information can lead to misinformation.

Objective

An interactive e-learning environment to promote digital health literacy will be developed and evaluated for effectiveness.

Primary hypothesis

Cancer patients who use the e-learning environment (IG1.1-IG1.3) or the content of the environment as a non-interactive PDF file (IG2) will show greater improvement in their digital health literacy from baseline to 8 weeks after baseline compared to patients who receive no such intervention, but are referred to a standard information brochure.

Methods

The hypothesis will be tested in a stratified randomized controlled superiority trial with five parallel groups and the primary endpoint of digital health literacy. In an e-learning environment, patients will learn strategies to use when searching for reliable cancer-related online information. During development, a prototype will be refined through focus groups and tested for usability by experts and patients. 660 cancer patients will be recruited using convenience sampling and randomly assigned in a 3:1:1 ratio to IG1.1-IG1.3 (three variants of the environment), IG2, or the control group. Two thirds of the 660 participants will be recruited through the German Cancer Information Service (CIS) and one third through non-CIS routes. Allocation will follow stratified randomization, accounting for recruitment route (CIS vs. non-CIS) and cancer type (breast cancer vs. other cancers), with variable block length. The primary outcome, digital health literacy, will be measured at baseline, 2 weeks, and 8 weeks after baseline.

Conclusion

If the results support the primary hypothesis, then the e-learning environment could empower patients to retrieve more reliable information about their disease. Concerns about the generalizability of the results, since a disproportionate number of inquiries to the CIS come from breast cancer patients, are addressed by a proportionally stratified randomization strategy and diversified recruitment routes.

First-site-metastasis pattern in patients with inoperable stage III NSCLC treated with concurrent chemoradiotherapy with or without immune check-point inhibition: a retrospective analysis

PURPOSE

The aim of this study was to investigate a first-site-metastasis pattern (FSMP) in unresectable stage III NSCLC after concurrent chemoradiotherapy (cCRT) with or without immune checkpoint inhibition (ICI).

METHODS

We defined three patient subgroups according to the year of initial multimodal treatment: A (2011-2014), B (2015-2017) and C (2018-2020). Different treatment-related parameters were analyzed. Observed outcome parameters were brain metastasis-free survival (BMFS), extracranial distant metastasis-free survival (ecDMFS) and distant metastasis-free survival (DMFS).

RESULTS

136 patients treated between 2011 and 2020 were included with ≥ 60.0 Gy total dose and concurrent chemotherapy (cCRT); thirty-six (26%) received ICI. Median follow-up was 49.7 (range:0.7-126.1), median OS 31.2 (95% CI:16.4-30.3) months (23.4 for non-ICI vs not reached for ICI patients, p = 0.001). Median BMFS/ecDMFS/DMFS in subgroups A, B and C was 14.9/16.3/14.7 months, 20.6/12.9/12.7 months and not reached (NR)/NR/36.4 months (p = 0.004/0.001/0.016). For cCRT+ICI median BMFS was 53.1 vs. 19.1 months for cCRT alone (p = 0.005). Median ecDMFS achieved 55.2 vs. 17.9 (p = 0.003) and median DMFS 29.5 (95% CI: 1.4-57.6) vs 14.93 (95% CI:10.8-19.0) months (p = 0.031), respectively. Multivariate analysis showed that age over 65 (HR:1.629; p = 0.036), GTV ≥ 78 cc (HR: 2.100; p = 0.002) and V20 ≥ 30 (HR: 2.400; p = 0.002) were negative prognosticators for BMFS and GTV ≥ 78 cc for ecDMFS (HR: 1.739; p = 0.027). After onset of brain metastasis (BM), patients survived 13.3 (95% CI: 6.4-20.2) months and 8.6 months (95% CI: 1.6-15.5) after extracranial-distant-metastasis (ecDM). Patients with ecDM as FSMP reached significantly worse overall survival of 22.1 (range:14.4-29.8) vs. 40.1 (range:18.7-61.3) months (p = 0.034) in the rest of cohort. In contrast, BM as FSMP had no impact on OS.

CONCLUSION

This retrospective analysis of inoperable stage III NSCLC patients revealed that age over 65, V20 ≥ 30 and GTV ≥ 78 cc were prognosticators for BMFS and GTV ≥ 78 cc for ecDMFS. ICI treatment led to a significant improvement of BMFS, ecDMFS and DMFS. ecDM as FSMP was associated with significant deterioration of OS, whereas BM as FSMP was not.

Understanding Trust Determinants in a Live Chat Service on Familial Cancer: Qualitative Triangulation Study With Focus Groups and Interviews in Germany

BACKGROUND

In dealing with familial cancer risk, seeking web-based health information can be a coping strategy for different stakeholder groups (ie, patients, relatives, and those suspecting an elevated familial cancer risk). In the vast digital landscape marked by a varied quality of web-based information and evolving technologies, trust emerges as a pivotal factor, guiding the process of health information seeking and interacting with digital health services. This trust formation in health information can be conceptualized as context dependent and multidimensional, involving 3 key dimensions: information seeker (trustor), information provider (trustee), and medium or platform (application). Owing to the rapid changes in the digital context, it is critical to understand how seekers form trust in new services, given the interplay among these different dimensions. An example of such a new service is a live chat operated by physicians for the general public with personalized cancer-related information and a focus on familial cancer risk.

OBJECTIVE

To gain a comprehensive picture of trust formation in a cancer-related live chat service, this study investigates the 3 dimensions of trust-trustor, trustee, and application-and their respective relevant characteristics based on a model of trust in web-based health information. In addition, the study aims to compare these characteristics across the 3 different stakeholder groups, with the goal to enhance the service's trustworthiness for each group.

METHODS

This qualitative study triangulated the different perspectives of medical cancer advisers, advisers from cancer support groups, and members of the public in interviews and focus group discussions to explore the 3 dimensions of trust-trustor, trustee, and application-and their determinants for a new live chat service for familial cancer risk to be implemented at the German Cancer Information Service.

RESULTS

The results indicate that experience with familial cancer risk is the key trustor characteristic to using, and trusting information provided by, the live chat service. The live chat might also be particularly valuable for people from minority groups who have unmet needs from physician-patient interactions. Participants highlighted trustee characteristics such as ability, benevolence, integrity, and humanness (ie, not a chatbot) as pivotal in a trustworthy cancer live chat service. Application-related characteristics, including the reputation of the institution, user-centric design, modern technology, and visual appeal, were also deemed essential. Despite the different backgrounds and sociodemographics of the 3 stakeholder groups, many overlaps were found among the 3 trust dimensions and their respective characteristics.

CONCLUSIONS

Trust in a live chat for cancer information is formed by different dimensions and characteristics of trust. This study underscores the importance of understanding trust formation in digital health services and suggests potential enhancements for effective, trustworthy interactions in live chat services (eg, by providing biographies of the human medical experts to differentiate them from artificial intelligence chatbots).

Between hope and reality: How oncology physicians and information providers of a cancer information service manage patients' expectations for and experiences with immunotherapies

OBJECTIVES

Immune checkpoint inhibitors have established themselves as a further therapeutic pillar in the treatment of various types of cancer. This can create challenges and possible misunderstandings for patients. The aim of this study was to assess the experiences of physicians and information providers in their interactions with patients about immunotherapy.

METHODS

The study design was exploratory with qualitative research methodology. We performed focus groups with 8 oncology physicians and 9 information providers of a cancer information service.

RESULTS

In the coding process, five focal points could be identified: (1) image of immunotherapy, (2) presentation of immunotherapy in the media, (3) hope, (4) creation of an information base, and (5) lessons learned and future directions. Physicians and information providers report that immunotherapy has a very positive image among patients. This seems to be due to the presentation of immunotherapy in the media and the positive associations of people with terms such as the immune system and the body's own defense.

CONCLUSIONS

In contrast to chemotherapy, patients are at risk of underestimating the early symptoms of serious side effects of immunotherapy. From the point of view of physicians, the exaggerated expectations of patients regarding the possibilities of immunotherapy are often not met. The challenge for practitioners is to consider patients' expectations to provide balanced information and recommendations.

PRACTICAL IMPLICATIONS

Communication skills training and up-to-date information tools should improve physician-patient communication.

Understanding the Pathway of Cancer Information Seeking: Cancer Information Services as a Supplement to Information from Other Sources

Cancer information services (CISs) can play an important role within the pathway of cancer information seeking, but so far, this role is not well understood. Callers (n = 6,255) who contacted the largest provider of cancer information in Germany participated in a survey in which they reported their information sources, information level, and needs leading to the call. Persons with prior information from a physician (n = 1,507) were compared to people with prior online information (n = 901) and people with prior information from both sources (n = 2,776). Nearly all callers (96.7%) stated prior sources, while physicians and the Internet were the most frequently reported sources. People, who only talked to a doctor before, are more likely to be a patient and in the disease stages during/after the first treatment or with recurrence than prior Internet users. The two groups do not differ in their prior information level but did differ in their information needs. CISs are an important supplement to other sources, while the information repertoire depends on patients' stages during the cancer journey. Specific characteristics and needs of callers with different prior information sources help to individualize the service of CISs and similar providers.

Preferred and perceived participation roles of oncological patients in medical decision-making: Results of a survey among users of the German Cancer Information Service

BACKGROUND

Cancer patients are facing a variety of treatment and other disease-related decisions. This study aims to provide insights into preferred and perceived participation roles in decision-making among patients with diverse tumors using the German Cancer Information Service (CIS).

METHODS

Patients' decision-making preferences and experiences were assessed as a part of a cross-sectional survey among CIS users. An adapted version of the Control Preferences Scale (CPS) was used to assess preferred and perceived participation roles in eight different areas of medical decision-making (e.g., choice of medication, termination of treatment). Logistic regression analyses were applied to explore preference matching and to analyze associations between participation roles and sociodemographic variables. Moreover, we examined preferences and perceptions of participation roles across different decision situations.

RESULTS

In the final sample (N = 1566, 64.9% female, mean age = 61.6), almost half of the patients (47.1%) preferred to take a collaborative role in decisions on treatment methods, whereas 36.3% preferred an active role and 15.9% a passive role. Collaborative role preferences frequently (40.7%) coincided with experiencing a passive role and predicted a reduced chance of a match between preferences and experiences (OR = 0.57, p = .001). A higher level of education was associated with a lower chance of preferring and perceiving a passive role (OR = 0.85, p < .01). Compared with men, women had increased odds of preferring (OR = 1.45, p < .05) and of actually taking (OR = 2.04, p < .001) a passive role in medical encounters. Preferred participation roles regarding treatment methods were highly correlated with preferences in all other decision areas (r > .50, p < .001) except decisions about family involvement.

CONCLUSIONS

The study reveals well-known deficits in the fulfilment of patients' collaborative role preferences across different areas of medical decision-making in a sample of CIS users characterized by high information-seeking behavior. Participation roles were not only influenced by the patients' level of education but also by their gender. The gender effect may be more pronounced than previous studies suggest. These effects should be considered in the development of interventions to promote shared decision-making. Additionally, study results indicate that preferences for participation in decisions about treatment methods, as assessed by the CPS, can be generalized to other areas of medical decision-making.

The COVID-19 Pandemic and Cancer Patients in Germany: Impact on Treatment, Follow-Up Care and Psychological Burden

In response to the ongoing coronavirus disease 2019 (COVID-19) pandemic, governments imposed various measures to decrease the rate of disease spread, and health care policy makers prioritized resource allocation to accommodate COVID-19 patients. We conducted a cross-sectional online survey in Germany (July 2020-June 2021) to assess the frequency of changes to cancer care among cancer patients and to explore the psychological impact of the pandemic writ large. Cancer patients who contacted the Cancer Information Service (Krebsinformationsdienst, KID) of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) via email were invited to complete an online questionnaire, capturing demographics, cancer specifics (e.g., type, disease phase, primary place of treatment, etc.), and any changes to their medical, follow-up, psycho-oncological or nursing care. General level of psychological distress was measured using the Hospital Anxiety and Depression Scale (HADS) along with face-validated items regarding worries and social isolation specific to the pandemic. In total, 13% of 621 patients reported a change to their treatment or care plan. Of those patients with changes, the majority of changes were made to follow-up care after treatment (56%), to monitoring during treatment (29%) and to psychological counseling (20%). Of the overall sample, more than half of patients (55%) reported symptoms of anxiety and 39% reported symptoms of depression. Patients with a change in cancer care were more likely to report symptoms of depression than those with no change (AOR: 2.18; 95% CI: 1.26-3.76). Concern about the pandemic affecting the quality of health care was a predictor of both anxiety (AOR: 2.76; 95% CI: 1.75-4.35) and depression (AOR: 2.15; 95% CI: 1.43-3.23). Results showed that the majority of cancer patients in our study did not experience a change in their cancer care. However, the level of anxiety and psycho-social burden of cancer patients during the pandemic was high throughout the study period. Our findings underscore the need for health care services and policy makers to assess and to attend cancer patients' medical needs, with added emphasis on patients' psychological and social well-being. This applies particularly in situations where the healthcare system is strained and prioritization is necessary.
