Use of Online Communication by Patients With Newly Diagnosed Breast Cancer During the Treatment Decision Process

Cancer Prevention and Treatment on Chinese Social Media: Machine Learning-Based Content Analysis Study

BACKGROUND

Nowadays, social media plays a crucial role in disseminating information about cancer prevention and treatment. A growing body of research has focused on assessing access and communication effects of cancer information on social media. However, there remains a limited understanding of the comprehensive presentation of cancer prevention and treatment methods across social media platforms. Furthermore, research comparing the differences between medical social media (MSM) and common social media (CSM) is also lacking.

OBJECTIVE

Using big data analytics, this study aims to comprehensively map the characteristics of cancer treatment and prevention information on MSM and CSM. This approach promises to enhance cancer coverage and assist patients in making informed treatment decisions.

METHODS

We collected all posts (N=60,843) from 4 medical WeChat official accounts (accounts with professional medical backgrounds, classified as MSM in this paper) and 5 health and lifestyle WeChat official accounts (accounts with nonprofessional medical backgrounds, classified as CSM in this paper). We applied latent Dirichlet allocation topic modeling to extract cancer-related posts (N=8427) and identified 6 cancer themes separately in CSM and MSM. After manually labeling posts according to our codebook, we used a neural-based method for automated labeling. Specifically, we framed our task as a multilabel task and utilized different pretrained models, such as Bidirectional Encoder Representations from Transformers (BERT) and Global Vectors for Word Representation (GloVe), to learn document-level semantic representations for labeling.

RESULTS

We analyzed a total of 4479 articles from MSM and 3948 articles from CSM related to cancer. Among these, 35.52% (2993/8427) contained prevention information and 44.43% (3744/8427) contained treatment information. Themes in CSM were predominantly related to lifestyle, whereas MSM focused more on medical aspects. The most frequently mentioned prevention measures were early screening and testing, healthy diet, and physical exercise. MSM mentioned vaccinations for cancer prevention more frequently compared with CSM. Both types of media provided limited coverage of radiation prevention (including sun protection) and breastfeeding. The most mentioned treatment measures were surgery, chemotherapy, and radiotherapy. Compared with MSM (1137/8427, 13.49%), CSM (2993/8427, 35.52%) focused more on prevention.

CONCLUSIONS

The information about cancer prevention and treatment on social media revealed a lack of balance. The focus was primarily limited to a few aspects, indicating a need for broader coverage of prevention measures and treatments in social media. Additionally, the study's findings underscored the potential of applying machine learning to content analysis as a promising research approach for mapping key dimensions of cancer information on social media. These findings hold methodological and practical significance for future studies and health promotion.

Vaccinations in hematological patients in the era of target therapies: Lesson learnt from SARS-CoV-2

Novel targeting agents for hematologic diseases often exert on- or off-target immunomodulatory effects, possibly impacting on response to anti-SARS-CoV-2 vaccinations and other vaccines. Agents that primarily affect B cells, particularly anti-CD20 monoclonal antibodies (MoAbs), Bruton tyrosine kinase inhibitors, and anti-CD19 chimeric antigen T-cells, have the strongest impact on seroconversion. JAK2, BCL-2 inhibitors and hypomethylating agents may hamper immunity but show a less prominent effect on humoral response to vaccines. Conversely, vaccine efficacy seems not impaired by anti-myeloma agents such as proteasome inhibitors and immunomodulatory agents, although lower seroconversion rates are observed with anti-CD38 and anti-BCMA MoAbs. Complement inhibitors for complement-mediated hematologic diseases and immunosuppressants used in aplastic anemia do not generally affect seroconversion rate, but the extent of the immune response is reduced under steroids or anti-thymocyte globulin. Vaccination is recommended prior to treatment or as far as possible from anti-CD20 MoAb (at least 6 months). No clearcut indications for interrupting continuous treatment emerged, and booster doses significantly improved seroconversion. Cellular immune response appeared preserved in several settings.

Patterns of social media use and associations with psychosocial outcomes among breast and gynecologic cancer survivors

PURPOSE

We sought to characterize the use of social media (SM) among breast and gynecologic cancer survivors, as well as associations between patterns of SM use and psychosocial outcomes.

METHODS

Two hundred seventy-three breast and gynecologic cancer survivors recruited at the Stanford Women's Cancer Center completed the study. Participants completed questionnaires to measure quality of life (FACT-G), functional social support (Duke-UNC FSSQ), distress (PHQ-4), decision regret (DRS), and SM use.

RESULTS

In total, 75.8% of the sample reported using SM. There was no difference in quality of life (QOL), functional social support (FSS), distress, or decision regret between SM users and non-users. SM users indicated using SM for social support (34.3%) and loneliness (24.6%) more than for information-seeking (15.9%), coping (18.8%), or self-disclosure (14%). SM use for coping was associated with lower QOL (p < .001), lower FSS (p < .001), and higher decision regret (p = .029). Use for social support was associated with lower FSS (p = .029). Use for information seeking was associated with lower QOL (p = .012). Use of SM when lonely was associated with lower QOL (p < .001), higher distress (p = .007), lower FSS (p < .001), and higher decision regret (p = .020).

CONCLUSIONS

Associations between SM use and psychosocial outcomes are nuanced and dependent on motivation for use. Further research is needed to better characterize SM use and associations with psychosocial outcomes among cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

SM is an important potential avenue for understanding and addressing the psychosocial effects associated with cancer survivorship.

A History of #BCSM and Insights for Patient-Centered Online Interaction and Engagement

Purpose

Participation in cancer support groups can provide a sense of community and may better prepare patients for interactions with their health care team. Online interactions may overcome some barriers to in-person support group participation. #BCSM (breast cancer social media), the first cancer support community established on Twitter, was founded in 2011 by two breast cancer survivors. The aims of this study are to describe the growth and changes in this community and to discuss future directions and lessons that may apply to other online support communities.

Methods

Symplur Signals was used to obtain all #BCSM Twitter data from January 1, 2011, to January 1, 2020 (00:00:00 Coordinated Universal Time for both). Hashtag use by selected stakeholder groups, user locations, weekly tweet chat activity, and topics were determined.

Results

From year 1 (2011) to year 9 (2019), tweets using the #BCSM hashtag increased by 424%. Tweets by patient advocates increased by 226%, with a peak in 2016. Impressions, a measure of potential tweet views, by patient advocates increased by 517%. Tweets by doctors and nonphysician health care professionals increased by 693%. Weekly #BCSM tweet chat activity peaked in 2013, increasing by 58.1% from 2011. Chat topics have included survivorship, metastatic breast cancer, death and dying, advocacy, and highlights from national breast cancer meetings.

Conclusions

#BCSM has experienced tremendous growth since 2011, although there are challenges to community sustainability. The weekly chats, as well as discussions utilizing the hashtag but occurring outside of scheduled chat times, serve as an important resource for patients and offer physicians an opportunity to both support and learn from patients.

How patients experience endocrine therapy for breast cancer: an online survey of side effects, adherence, and medical team support

PURPOSE

Many patients with hormone receptor-positive (HR+) breast cancer do not adhere to endocrine therapy (ET), and treatment-related side effects are often discussed by participants in online breast cancer forums. Our aim was to survey this unique group of patients about their ET-related experiences.

METHODS

We partnered with patients active in breast cancer social media communities to develop a survey assessing ET-related side effects and medical team communication. Patients with a history of HR+ breast cancer who had received a recommendation to take ET were eligible to participate in the anonymous, online survey.

RESULTS

Respondents included 2353 women and 54 men. Aromatase inhibitors were the most commonly used medication. Side effects were reported by 91.2%, were more often experienced by women than men (p < 0.001), and were primarily related to medication type. Approximately one-third of respondents discontinued therapy early. While most felt supported by their medical team, 31.5% reported that their side effects were dismissed or minimized. Survey respondents most frequently reported that a healthy diet and exercise, yoga/acupuncture, and vitamins/supplements were helpful in managing ET-related side effects.

CONCLUSIONS

ET-related side effects are very common, and one-third discontinued treatment early. Lifestyle changes and complementary therapies can be important tools for side effect management. One-third of patients did not feel that their side effects were taken seriously.

IMPLICATIONS FOR CANCER SURVIVORS

This is the largest survey of ET use by participants in online breast cancer communities. Further research is needed to identify strategies to improve treatment adherence and to better manage ET-related side effects.

Patient-Perceived Lack of Choice in Receipt of Radioactive Iodine for Treatment of Differentiated Thyroid Cancer

PURPOSE

For many patients with differentiated thyroid cancer, use of radioactive iodine (RAI) does not improve survival or reduce recurrence risk. Yet there is wide variation in RAI use, emphasizing the importance of understanding patient perspectives regarding RAI decision making.

PATIENTS AND METHODS

All eligible patients diagnosed with thyroid cancer from 2014 to 2015 from the Georgia and Los Angeles SEER registries were surveyed (N = 2,632; response rate, 63%). Patients in whom selective RAI use is recommended were included in this analysis (n = 1,319). Patients were asked whether they felt like they had a choice to receive RAI (yes or no), how strongly their physician recommended RAI (5-point Likert-type scale), whether they received RAI (yes or no), and how satisfied they were with their RAI decision (more [score of 4 or greater] v less). Multivariable, weighted logistic regression with multiple imputation was used to assess the associations between patient characteristics and perception of no RAI choice and between perception of no RAI choice with receipt of RAI and decision satisfaction.

RESULTS

More than half of respondents (55.8%) perceived they did not have an RAI choice, and the majority of patients (75.9%) received RAI. The odds of perceiving no RAI choice was greater among those whose physician strongly recommended RAI (adjusted odds ratio [OR], 1.56; 95% CI, 1.13 to 2.17). Patients who perceived they did not have an RAI choice were more likely to receive RAI (adjusted OR, 2.50; 95% CI, 1.64 to 3.82) and report lower decision satisfaction (adjusted OR, 2.31; 95% CI, 1.67 to 3.20).

CONCLUSION

Many patients did not feel they had a choice about whether to receive RAI. Patients who perceived they did not have a choice were more likely to receive RAI and report lower decision satisfaction, suggesting a need for more shared decision making to reduce overtreatment.

Primary care provider-reported involvement in breast cancer treatment decisions

BACKGROUND

Treatment decisions for patients with early-stage breast cancer often involve discussions with multiple oncology providers. However, the extent to which primary care providers (PCPs) are involved in initial treatment decisions remains unknown.

METHODS

A stratified random sample of PCPs identified by newly diagnosed patients with early-stage breast cancer from the Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries were surveyed (n = 517; a 61% response rate). PCPs were asked how frequently they discussed surgery, radiation, and chemotherapy options with patients; how comfortable they were with these discussions; whether they had the necessary knowledge to participate in decision making; and what their confidence was in their ability to help (on 5-item Likert-type scales). Multivariate logistic regression was used to identify PCP-reported attitudes associated with more PCP participation in each treatment decision.

RESULTS

In this sample, 34% of PCPs reported that they discussed surgery, 23% discussed radiation, and 22% discussed chemotherapy options with their patients. Of those who reported more involvement in surgical decisions, 22% reported that they were not comfortable having a discussion, and 17% did not feel that they had the necessary knowledge to participate in treatment decision making. PCPs who positively appraised their ability to participate were more likely to participate in all 3 decisions (odds ratio [OR] for surgery, 6.01; 95% confidence interval [CI], 4.16-8.68; OR for radiation, 8.37; 95% CI, 5.16-13.58; OR for chemotherapy, 6.56; 95% CI, 4.23-10.17).

CONCLUSIONS

A third of PCPs reported participating in breast cancer treatment decisions, yet gaps in their knowledge about decision making and in their confidence in their ability to help exist. Efforts to increase PCPs' knowledge about breast cancer treatment options may be warranted.

What Young Women with Breast Cancer Get Versus What They Want in Online Information and Social Media Supports

Purpose: Young women are high users of social media (SM), but information is lacking on whether online supports including SM meet the needs of young women (<40 years) with breast cancer (YWBC). YWBC are a vulnerable population who experience many psychosocial challenges alongside cancer diagnosis and treatment. This study aimed to gather data on what YWBC get versus what they want in online support. Methods: Semi-structured interviews explored YWBC's perceptions and use of online information/SM, including visions for ideal support. YWBC between the ages of 18-40 were recruited via two urban oncology clinics. Recruitment continued until redundancy of responses was achieved. Results: Thirteen YWBC participated in the study. Some reported benefits of online supports included connection with similar others, emotional support and ease of use. These benefits were balanced by drawbacks, such as a lack of appropriate/credible information and/or distressing information. Respondents spontaneously mentioned coping strategies such as managing information exposure and regulating SM use to mitigate against harms of online supports. Collectively, participants described nine facets of an ideal online support hub, which could function as a one stop shop for informational, practical and emotional supports for YWBC. Conclusion: Developing a multifunction online support hub may help women to find credible and useful information, rapidly, and address current limitations of online supports.

Decision-support networks of women newly diagnosed with breast cancer

BACKGROUND

Little is known about the size and characteristics of the decision-support networks of women newly diagnosed with breast cancer and whether their involvement improves breast cancer treatment decisions.

METHODS

A population-based sample of patients newly diagnosed with breast cancer in 2014 and 2015, as reported to the Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries, were surveyed approximately 7 months after diagnosis (N = 2502; response rate, 68%). Network size was estimated by asking women to list up to 3 of the most important decision-support persons (DSPs) who helped them with locoregional therapy decisions. Decision deliberation was measured using 4 items assessing the degree to which patients thought through the decision, with higher scores reflecting more deliberative breast cancer treatment decisions. The size of the network (range, 0-3 or more) was compared across patient-level characteristics, and adjusted mean deliberation scores were estimated across levels of network size using multivariable linear regression.

RESULTS

Of the 2502 women included in this analysis, 51% reported having 3 or more DSPs, 20% reported 2, 18% reported 1, and 11% reported not having any DSPs. Married/partnered women, those younger than 45 years, and black women all were more likely to report larger network sizes (all P < .001). Larger support networks were associated with more deliberative surgical treatment decisions (P < .001).

CONCLUSIONS

Most women engaged multiple DSPs in their treatment decision making, and involving more DSPs was associated with more deliberative treatment decisions. Future initiatives to improve treatment decision making among women with breast cancer should acknowledge and engage informal DSPs. Cancer 2017;123:3895-903. © 2017 American Cancer Society.

Increase in contralateral prophylactic mastectomy conversation online unrelated to decision-making

BACKGROUND

The increased uptake of contralateral prophylactic mastectomy (CPM) among breast cancer patients remains poorly understood. We hypothesized that the increased rate of CPM is represented in conversations on an online breast cancer community and may contribute to patients choosing this operation.

METHODS

We downloaded 328,763 posts and their dates of creation from an online breast cancer community from August 1, 2000, to May 22, 2016. We then performed a keyword search to identify posts which mentioned breast cancer surgeries: contralateral prophylactic mastectomy (n = 7095), mastectomy (n = 10,889), and lumpectomy (n = 9694). We graphed the percentage of CPM-related, lumpectomy-related, and mastectomy-related conversations over time. We also graphed the frequency of posts which mentioned multiple operations over time. Finally, we performed a qualitative study to identify factors influencing the observed trends.

RESULTS

Surgically related posts (e.g., mentioning at least one operation) made up a small percentage (n = 27,678; 8.4%) of all posts on this community. The percentage of surgically related posts mentioning CPM was found to increase over time, whereas the percentage of surgically related posts mentioning mastectomy decreased over time. Among posts that mentioned more than one operation, mastectomy and lumpectomy were the procedures most commonly mentioned together, followed by mastectomy and CPM. There was no change over time in the frequency of posts that mentioned more than one operation. Our qualitative review found that most posts mentioning a single operation were unrelated to surgical decision-making; rather the operation was mentioned only in the context of the patient's cancer history. Conversely, the most posts mentioning multiple operations centered around the patients' surgical decision-making process.

CONCLUSIONS

CPM-related conversation is increasing on this online breast cancer community, whereas mastectomy-related conversation is decreasing. These results appear to be primarily informed by patients reporting the types of operations they have undergone, and thus appear to correspond to the known increased uptake of CPM.

Social media for breast cancer survivors: a literature review

PURPOSE

Social media may offer support to individuals who are navigating the complex and challenging experience of cancer. A growing body of literature has been published over the last decade exploring the ways cancer survivors utilize social media. This study aims to provide a systematic synthesis of the current literature in order to inform cancer health communication practice and cancer survivorship research.

METHODS

Using PRISMA guidelines, four electronic databases were searched to retrieve publications on breast cancer and social media published between 2005 and 2015. The final sample included 98 publications (13 commentaries and reviews, 47 descriptive studies, and 38 intervention studies). Intervention studies were assessed for key features and outcome measures. Studies utilizing content analysis were further evaluated qualitatively.

RESULTS

Online support groups were the most commonly studied platform, followed by interactive message boards and web forums. Limited research focuses on non-Caucasian populations. Psychosocial well-being was the most commonly measured outcome of interest. While social media engagement was assessed, few standardized measures were identified. Content analyses of social media interactions were prevalent, though few articles linked content to health outcomes.

CONCLUSIONS

The current literature highlights the impact and potential utility of social media for breast cancer survivors. Future studies should consider connecting social media engagement and content to psychosocial, behavioral, and physical health outcomes.

IMPLICATIONS FOR CANCER SURVIVORS

Online groups and communities may improve the well-being of breast cancer survivors by providing opportunities to engage with wider social networks, connect with others navigating similar cancer experiences, and obtain cancer-related information. Researchers should consider the potential role of social media in addressing the unmet needs of breast cancer survivors, and particularly the implications for clinical and public health practice.
