Socioeconomic Disparities in Anal Cancer: Effect on Treatment Delay and Survival.

BACKGROUND: Socioeconomic inequities have implications for access to health care and may be associated with disparities in treatment and survival. OBJECTIVE: To investigate the impact of socioeconomic inequities on time to treatment and survival of anal squamous-cell carcinoma. DESIGN: This is a retrospective study using a nationwide data set. SETTINGS: The patients were selected from the National Cancer Database and enrolled from 2004 to 2016. PATIENTS: We identified patients with stage I to III squamous-cell carcinoma of the anus who were treated with chemoradiation therapy. MAIN OUTCOMES MEASURES: Socioeconomic factors, including race, insurance status, median household income, and percentage of the population with no high school degrees, were included. The association of these factors with treatment delay and overall survival was investigated. RESULTS: A total of 24,143 patients who underwent treatment for grade I to III squamous-cell carcinoma of the anus were identified. The median age was 60 years, and 70% of patients were women. The median time to initiation of treatment was 33 days. Patients from zip codes with lower median income, patients with a higher percentage of no high school degree, and patients with other government insurance followed by Medicaid insurance had treatment initiated after 60 days from diagnosis. Kaplan-Meier survival analysis showed that the late-treatment group had worse overall survival compared to the early treatment group (98 vs 125 months; p < 0.001). LIMITATIONS: No detailed information is available about the chemoradiotherapy regimen, completion of treatment, recurrence, disease-free survival, and individual-level socioeconomic condition and risk factors. CONCLUSION: Patients from communities with lower median income, level of education, and enrolled in public insurance had longer time to treatment. Lower socioeconomic status was also associated with poorer overall survival. These results warrant further analysis and measures to improve access to care to address this disparity.

DESIGUALDADES SOCIOECONMICAS EN CASOS DE CNCER ANAL EFECTOS EN EL RETRASO DEL TRATAMIENTO Y LA SOBREVIDA: ANTECEDENTES:Las desigualdades socio-económicas tienen implicaciones en el acceso a la atención médica y pueden estar asociadas con disparidades en el tratamiento y la sobrevida.OBJETIVO:Indagar el impacto de las desigualdades socio-económicas sobre el tiempo de retraso en el tratamiento y la sobrevida en casos de carcinoma a células escamosas del ano (CCEA).DISEÑO:Estudio retrospectivo utilizando un conjunto de datos a nivel nacional.AJUSTES:Todos aquellos pacientes inscritos entre 2004 a 2016 y que fueron seleccionados de la Base Nacional de Datos sobre el Cáncer.PACIENTES:Identificamos pacientes con CCEA en estadíos I-III y que fueron tratados con radio-quimioterápia.PRINCIPALES MEDIDAS DE RESULTADOS:Se incluyeron factores socio-económicos tales como la raza, el tipo de seguro de salud, el ingreso familiar medio y el porcentaje de personas sin bachillerato de secundaria (SBS). Se investigó la asociación entre estos factores con el retraso en iniciar el tratamiento y la sobrevida global.RESULTADOS:Se identificaron un total de 24.143 pacientes que recibieron tratamiento para CCEA estadíos I-III. La mediana de edad fue de 60 años donde 70% eran de sexo femenino. La mediana del tiempo transcurrido desde el diagnóstico hasta el inicio del tratamiento fue de 33 días. Los pacientes residentes en zonas de código postal con ingresos medios más bajos, con un mayor porcentaje de individuos SBS y los pacientes con otro tipo de seguro gubernamental de salud, seguidos del seguro tipo Medicaid iniciaron el tratamiento solamente después de 60 días al diagnóstico inicial de CCEA. El análisis de Kaplan-Meier de la sobrevida mostró que el grupo de tratamiento tardío tuvo una peor supervivencia general comparada con el grupo de tratamiento precoz o temprano (98 frente a 125 meses; p <0,001).LIMITACIONES:No se dispone de información detallada sobre el tipo de radio-quimioterapia utilizada, ni sobre la finalización del tratamiento o la recurrencia, tampoco acerca de la sobrevida libre de enfermedad ni sobre las condiciones socio-económicas o aquellos factores de riesgo a nivel individual.CONCLUSIÓN:Los pacientes de comunidades con ingresos medios más bajos, con un nivel de educación limitado e inscritos en un seguro público tardaron mucho más tiempo en recibir el tratamiento prescrito. El nivel socio-económico más bajo también se asoció con una sobrevida global más baja. Los presentes resultados justifican mayor análisis y medidas mas importantes para mejorar el acceso a la atención en salud y poder afrontar esta disparidad. (Traducción-Dr. Xavier Delgadillo ).

Brief culturally informed smartphone interventions decrease breast cancer symptom burden among Latina breast cancer survivors.

OBJECTIVE: Latina breast cancer survivors (BCS) report more symptom burden and poorer health-related quality of life than non-Latina BCS. However, there are few evidence-based and culturally informed resources that are easily accessible to this population. This study aimed to establish the feasibility and preliminary efficacy of the My Guide and My Health smartphone applications among Latina BCS. Both applications are culturally informed and contain evidence-based information for reducing symptom burden and improving health-related quality of life (My Guide) or healthy lifestyle promotion (My Health). METHODS: Participants (N = 80) were randomized to use the My Guide or My Health smartphone applications for 6 weeks. Assessments occurred at baseline (T1) after the 6-week intervention (T2) and 2-week post-T2 (T3). Outcomes were participant recruitment and retention rates, patient-reported satisfaction, and validated measures of symptom burden and health-related quality of life. RESULTS: Recruitment was acceptable (79%), retention was excellent (>90%), and over 90% of participants were satisfied with their application. On average, participants in both conditions used the applications for more than 1 hour per week. Symptom burden declined from T1 to T2 across both conditions, but this decline was not maintained at T3. Breast cancer well-being improved from T1 to T2 across both conditions and was maintained at T3. CONCLUSIONS: Latina BCS who used the My Guide and My Health applications reported temporary decreases in symptom burden and improved breast cancer well-being over time, though there were no differential effects between conditions. Findings suggest that technology may facilitate Latina BCS engagement in care after breast cancer treatment.

My health smartphone intervention decreases daily fat sources among Latina breast cancer survivors.

Breast cancer is the most common cancer among Latina women, and Latina women are at higher risk for breast cancer mortality than white women. Lifestyle factors, such as consuming a nutritious diet and engaging in regular physical activity, promote health and are protective against heart disease, type 2 diabetes, and breast cancer recurrence. Previous studies have developed and tested interventions for Latina breast cancer survivors to improve diet and increase physical activity, however, no studies to date have developed a smartphone delivered intervention. The purpose of the current study was to compare two Smartphone delivered interventions, My Health, which focused on diet and physical activity, and My Guide, which focused on psychosocial functioning, on dietary and physical activity outcomes, post-intervention, and at a 2-week follow-up assessment. Overall, participants receiving the My Health intervention reported a greater reduction in daily fat sources than the My Guide group over time. However, daily sources of fat did not differ between conditions. Walking, measured by estimated weekly metabolic equivalents, increased across time points in both groups. These preliminary findings suggest that eHealth interventions aimed at improving lifestyle factors may favorably impact nutritional intake and physical activity. Future research should utilize more comprehensive and objective measures of diet and physical activity, and incorporate more behavioral lifestyle components into the intervention in larger samples with a longer follow-up period.

Cancer-Relevant Self-Efficacy Is Related to Better Health-Related Quality of Life and Lower Cancer-Specific Distress and Symptom Burden Among Latina Breast Cancer Survivors.

BACKGROUND: Latina breast cancer survivors (BCS) often report poorer health-related quality of life (HRQOL), higher symptom burden, and greater psychosocial needs compared to non-Latina BCS. However, Latinas are underrepresented in cancer survivorship research and more work is needed to examine the factors contributing to these psychosocial disparities. This study aimed to evaluate potentially modifiable patient characteristics associated with HRQOL, breast cancer concerns, and cancer-specific distress among Latina BCS. METHODS: Baseline data was evaluated in 95 Latina BCS who participated in a smartphone-based psychosocial intervention designed to improve HRQOL. Hierarchical linear regression analyses were conducted to evaluate the associations between modifiable factors that have been shown to favorably impact outcomes in cancer populations (i.e., cancer-relevant self-efficacy, breast cancer knowledge) with overall and domain-specific HRQOL, breast cancer symptom burden, and cancer-specific distress, after controlling for sociodemographic and cancer-related characteristics. RESULTS: Greater cancer-relevant self-efficacy was related to better overall HRQOL as well as better social, emotional, and functional well-being domains. Greater cancer-relevant self-efficacy was also related to less breast cancer symptom burden and less cancer-specific distress. Breast cancer knowledge was not associated with any of the study outcomes. CONCLUSIONS: Results demonstrate that cancer-relevant self-efficacy is a significant correlate of general and domain-specific HRQOL, breast cancer symptom burden, and cancer-specific distress among Latina BCS. Future interventions in this population should target cancer-relevant self-efficacy as a possible mechanism to improve HRQOL outcomes and survivorship experiences for Latina BCS.

Deconstructing One Medical School's Pain Curriculum: I. Content Analysis.

Objective: Inventory one medical school's first- and second-year pain-related curriculum in order to explore opportunities to teach about pain both as a social, population-based process and as a neuron-centered phenomenon. Design: Deconstruction of pain-related curricular content through a detailed content inventory and analysis by students and faculty. Setting and Subjects: University-affiliated US medical school. Methods: Detailed inventory and content analysis of first- and second-year curricular materials. Results: The inventory of pain content showed fragmentation, mostly presenting it as a symptom without an underlying framework. Conclusion: Analysis of one medical school's pain-related curricular materials reveals opportunities for a more unified perspective that includes pain as a widespread disease state (not merely a symptom) and to provide an emphasis in the curriculum consistent with pain's public health burden.

Deconstructing One Medical School's Pain Curriculum: II. Partnering with Medical Students on an Evidence-Guided Redesign.

Objective: To reshape medical education about pain to present it as a population-based public health process as well as a neuron-centered phenomenon. Design: Collaborate with students to apply a recent inventory of pain-related preclinical curricular content and clinical training in order to modify the current multiyear presentation and offer a broadened social perspective on pain. Appraise fourth-year medical students' pain-related educational needs by surveying their knowledge, attitudes, experience with the curriculum, and self-reported assessment of pain-related competencies. Setting and subjects: University-affiliated medical school and its fourth-year medical students. Methods: Analysis of a detailed inventory of first- and second-year curricula. Survey of graduating medical students assessing attitudes, skills, and confidence. Construction of a fourth-year pain education elective and collaboration with enrollees to better integrate pain throughout the four-year curriculum. Results: This student-faculty collaboration produced an evidence-guided proposal to reorganize pain-related content across the longitudinal medical curriculum. An attitudes/skills/confidence survey of graduating medical students (104 respondents of 200 polled) found that 70% believed chances for successful outcomes treating chronic pain were low. Self-evaluated competency was high for evaluating (82%) and managing (69%) acute pain; for chronic pain, both were lower (evaluating = 38%; managing = 6%). Self-evaluated knowledge of pain physiology and neurobiology was poor (14%), fair (54%), or good (30%), but rarely excellent (2%). Conclusions: To meet graduating students' desire for increased competency in pain, pain-related curricula can and should be reorganized to include pain as a disease state and a widespread public health burden, not merely a symptom.

Pelvic Necrosis with Formation of a Pelvic "Cloaca" and Necrotizing Soft Tissue Infection After Radiation for Anal Squamous Cell Carcinoma.

BACKGROUND Anal squamous cell carcinoma (SCC) is a rare cancer commonly treated with the Nigro protocol, which combines chemotherapy and radiation. Patients who received radiation therapy prior to modern advances, such as computer-based tumor targeting, volumetric planning, and intensity-modulated radiation therapy, experience more acute and chronic adverse effects. Though exceedingly rare, radiation necrosis is of particular concern, as it can result in significant morbidity and mortality, including complex pelvic fistula formation and predisposition to potentially life-threatening necrotizing soft-tissue infections. CASE REPORT Here, we present a case of a 66-year-old woman with a prior history of anal SCC stage T3N×M0 who was treated with the Nigro protocol. Her treatment course was complicated by radiation proctitis, necessitating fecal diversion and ureteral strictures, requiring frequent stent exchanges. She presented 18 years after her cancer treatment, with widespread necrosis of her pelvic organs and surrounding soft tissue, resulting in formation of a large pelvic "cloaca", with a superimposed necrotizing soft-tissue infection. She was successfully treated by expedited resuscitation, septic source control, using multiple extensive debridements, and complete urinary diversion, utilizing a multidisciplinary team. CONCLUSIONS This case highlights the importance of monitoring patients for signs of radiation toxicity, particularly in patients who received radiation prior to the latest technological advancements, as they are at increased risk of developing severe, late adverse effects decades after treatment. When these complications are recognized, early and aggressive intervention is required to spare the patient significant morbidity and mortality.

Outcomes of perineal wound closure techniques after abdominoperineal resections in rectal cancer: an NSQIP propensity score matched study.

Perineal defects following abdominoperineal resections (APRs) for rectal cancer may require myocutaneous or omental flaps depending upon anatomic, clinical and oncologic variables. However, studies comparing their efficacy have shown contradictory results. We aim to compare postoperative complication rates of APR closure techniques in rectal cancer using propensity score-matching. The American College of Surgeons Proctectomy Targeted Data File was queried from 2016 to 2019. The study population was defined using CPT and ICD-10 codes for patients with rectal cancer undergoing APR, stratified by repair technique. Perioperative demographic and oncologic variables were controlled for by propensity-score matching. Multivariate logistic regression analysis was performed for wound and major complications (MCs). Of the 3291 patients included in the study, 85% underwent primary closure (PC), 8.3% rectus abdominis myocutaneous (RAM) flap, 4.9% pedicled omental flap with PC, and 1.9% lower extremity (LE) flap repair. Primary closure rates were significantly higher for patients with stage T1 and T2 tumors (p < 0.001). RAM and LE flaps were most used with multi-organ resections, 24% and 25%, respectively (p < 0.001). Similarly, cases with T4 tumors used these flaps more frequently, 30% and 40%, respectively (p < 0.001). After propensity score matching for comorbidities and oncologic variables, there was no significant difference in 30-day postoperative wound or MC rates between perineal closure techniques. The complication rates of the different closure techniques are comparable when tumor stage is considered. Therefore, tumor staging and concurrent procedures should guide clinical decision making regarding the appropriate use of each technique.

Comparison of Perineal Closure Techniques after Abdominoperineal Resections for Carcinoma of the Anus.

BACKGROUND: Perineal reconstruction following salvage APR's for squamous cell carcinoma of the anus (SCCA) are scant with conflicting results from large and single center studies. We analyzed these techniques taking into account sociodemographic and oncologic variables. METHODS: This is a retrospective cohort study from 2016-2019 using a targeted ACS/NSQIP database stratified into primary closure (PC), abdominal myocutaneous (AM), lower extremity (LE), and omental pedicled (OP) flaps. We analyzed major and wound complications through univariate and multivariate regression analysis. RESULTS: A total of 766 patients were analyzed, 512 (67%) had PC, 196 (25%) AM, 36 (5%) OP and 22 (3%) LE. Rates of chemotherapy and radiation within 90 days were similar between the groups. Having 2 or more additional organs resected was more common for the AM group (AM 4.1%, PC 1.6%, OP 3.3%, LE 0%). Overall, major complication rate was 41% (n = 324). Primary closure had 35.0%, OP 47.2%, AM 52.6%, and LE 45.5%. Wound complication rate was highest in AM with 11.7%, followed by OP 8.3%, PC 5.9%, and LE 0%. The multivariate regression analysis demonstrated none of the closure techniques to be associated with increasing or decreasing the probability of having a major or wound complication. Morbidity probability was the sole predictor of major complication (OR 1.07, 95% CI 1.04-1.1). CONCLUSIONS: Myocutaneous and omental flaps are associated with comparable wound and major complications when taking into account the baseline, oncologic and perioperative variables that drive the clinical decision making when selecting a perineal reconstruction.

Anal Adenocarcinoma Arising From a Fistula-in-Ano: A Case Report.

Crohn's disease (CD) is an inflammatory disease that can affect any portion of the gastrointestinal tract (GIT). Although it can present with a number of complications, perianal fistulae are among the most common consequences in patients with CD. In very rare cases, these patients can develop fistula-associated anal adenocarcinoma (FAAA). In this case report, we discuss a 72-year-old man with a long-term history of CD complicated by perianal fistulae, which failed medical and surgical management, ultimately presenting with acute anal pain in the outpatient setting. The physical examination revealed a seton traversing through a fistula surrounded by circumferential granulation tissue suspicious for malignancy. A biopsy of the tissue confirmed grade 3 mucinous-type infiltrating adenocarcinoma of the perianal skin. The patient was diagnosed with an anal verge malignancy associated with a fistula in the context of long-standing CD, and MRI staging demonstrated a T3N1 lesion with potential left inguinal node involvement. He completed neoadjuvant chemo-radiotherapy using capecitabine for five weeks with minimal tumor response, and subsequently, an abdominoperineal resection (APR) was performed with patient discharge on the fifth post-procedure day. Post-operative chemotherapy with oxaliplatin/leucovorin/fluorouracil was administered with minimal complications. Although rare, this report demonstrates the importance of consistent follow-up and mitigation of risk factors in patients with CD, along with the significance of prompt multimodal treatment in the event of developing FAAA.

Patterns of Use of Smartphone-Based Interventions Among Latina Breast Cancer Survivors: Secondary Analysis of a Pilot Randomized Controlled Trial.

BACKGROUND: Latina breast cancer survivors experience poorer health-related quality of life (HRQoL), greater symptom burden, and more psychosocial needs compared to non-Latina breast cancer survivors. eHealth platforms such as smartphone apps are increasingly being used to deliver psychosocial interventions to cancer survivors. However, few psychosocial eHealth interventions have been developed specifically for Latina breast cancer survivors. Further, little is known about how Latinas, in general, engage with eHealth interventions and whether specific participant characteristics are associated with app use in this population. We evaluated the use of 2 culturally informed, evidence-based smartphone apps for Latina breast cancer survivors-one that was designed to improve HRQoL and reduce symptom burden (My Guide) and the other to promote healthy lifestyle behaviors (My Health). OBJECTIVE: The objectives of our study were to explore the patterns of use of the My Guide intervention app and My Health attention-control app among Latina breast cancer survivors. METHODS: Eighty Latina breast cancer survivors were randomized to use the My Guide or My Health app for 6 weeks. Assessments were collected at baseline (T1), immediately after the 6-week intervention (T2), and 2 weeks after T2 (T3). Specific study outcomes included subdomains of HRQoL, symptom burden, cancer-specific distress, cancer-relevant self-efficacy, and breast cancer knowledge. RESULTS: On average, participants used their assigned app for more than 1 hour per week. Sociodemographic or psychological characteristics were not significantly associated with app use, except for employment status in the My Health group. Content related to common physical and emotional symptoms of breast cancer survivors as well as recommendations for nutrition and physical activity were most frequently accessed by My Guide and My Health participants, respectively. Lastly, clinically meaningful improvements were demonstrated in breast cancer well-being among low app users (ie, <60 minutes of use/week) of My Guide and social well-being among high app users (ie, ≥60 minutes of use/week) of My Health. CONCLUSIONS: The favorable rates of participant use across both apps suggest that Latina breast cancer survivors are interested in the content delivered across both My Guide and My Health. Furthermore, since sociodemographic variables, excluding employment status, and baseline HRQoL (psychological variable) were not related to app use, My Guide and My Health may be accessible to diverse Latina breast cancer survivors.

Community Perspectives: Developing and Implementing a Smartphone Intervention for Latina Breast Cancer Survivors in Chicago.

Compared with non-Latina White breast cancer survivors (BCS), Latina BCS have poorer health-related quality of life and greater psychosocial needs. However, Latinas are less engaged in clinical research owing to barriers including less access to health-related information, less awareness of clinical trials, and practical barriers (e.g., competing time demands). Latina BCS are in need of educational and health-related resources that are culturally informed, scalable, and accessible. In 2015, the Chicago Cancer Health Equity Collaborative (ChicagoCHEC), a National Cancer Institute research collaborative, and ALAS-WINGS, a community organization providing educational and supportive resources to Latina BCS, partnered to develop My Guide. My Guide is a smartphone application-based intervention for Latina BCS designed to improve health-related quality of life (HRQOL). This article summarizes the experiences of ChicagoCHEC and ALAS-WINGS throughout the community-engaged research (CEnR) partnership. Using existing relationships in community and academic settings via CEnR provides an ideal starting point for tailoring resources to Latina BCS and engaging Latina BCS in health-related research.

Feasibility of a Smartphone-based pilot intervention for Hispanic breast cancer survivors: a brief report.

Hispanic breast cancer survivors (BCS) are at high risk for experiencing poor health-related quality of life (HRQoL) after completion of active breast cancer treatment. Therefore, there is a need to develop culturally tailored interventions for Hispanic BCS. To date, there have been limited interventions that have demonstrated that increasing cancer-related knowledge, self-efficacy in communication, and self-management skills can improve HRQoL among Hispanic BCS. These interventions have been delivered in person or by phone, which may be burdensome for Hispanic BCS. To facilitate intervention delivery, we developed My Guide, a Smartphone application aimed at improving HRQoL among Hispanic BCS. The purpose of the current study is to describe the feasibility results of a 4-week pilot trial testing My Guide among Hispanic BCS. Twenty-five women enrolled in the study (75% recruitment rate) and 22 women were retained (91.6% retention rate). Mean time spent using My Guide across the 4 weeks was 9.25 hr, and mean score on the satisfaction survey was 65.91 (range 42-70), in which higher scores reflect greater satisfaction. Participants' scores on the Breast Cancer Knowledge Questionnaire significantly improved from study baseline (M = 9.50, SD = 2.92) to the postintervention assessment (M = 11.14, SD = 2.66), d = 0.59. Participants' HRQoL scores improved over the course of 4 weeks, but these improvements were not statistically significant. Overall, My Guide was feasible and acceptable. Future studies will assess the preliminary efficacy of My Guide in improving HRQoL in a larger, randomized trial of Hispanic BCS.

An Electronic Health Intervention for Latina Women Undergoing Breast Cancer Treatment (My Guide for Breast Cancer Treatment): Protocol for a Randomized Controlled Trial.

BACKGROUND: Among Latinas and Hispanics (henceforth referred to as Latinas), breast cancer is the most commonly diagnosed cancer and the leading cause of cancer-related deaths. However, few interventions have been developed to meet the needs of Latina women undergoing active treatment for breast cancer. OBJECTIVE: This paper aims to describe the procedures and methods of My Guide for Breast Cancer Treatment and the plans for conducting a multisite randomized controlled trial to investigate the feasibility and preliminary efficacy of this smartphone-based app for Latina women in active treatment for breast cancer. METHODS: Study participants will be randomized to the My Guide for Breast Cancer Treatment intervention or the enhanced usual care control condition for 12 weeks. Participants will have access to innovative features such as gamification via virtual awards to reinforce usage and an adaptive section that presents targeted material based on their self-reported concerns and needs. Using a stepped-care approach, intervention participants will also receive telecoaching to enhance their adherence to the app. Study outcomes and intervention targets will be measured at study enrollment (before randomization), 6 and 12 weeks after initial app use. General and disease-specific health-related quality of life (HRQoL) and symptom burden are the study's primary outcomes, whereas anxiety, depression, fear of cancer recurrence, physical activity, and dietary intake are secondary outcomes. RESULTS: Recruitment began in August 2019 and is expected to be completed by August 2020. We expect to submit study results for publication by fall 2020. CONCLUSIONS: My Guide for Breast Cancer Treatment has the potential to improve HRQoL and reduce symptom burden, and increase access to supportive care resources among Latina breast cancer patients. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): PRR1-10.2196/14339.

Study design and protocol for My Guide: An e-health intervention to improve patient-centered outcomes among Hispanic breast cancer survivors.

Breast cancer is the most commonly diagnosed non-skin cancer in women and the leading cause of death among Hispanic women living in the United States. Relative to non-Hispanic white women, Hispanic women report poorer health related quality of life (HRQoL) after treatment. Although eHealth interventions delivered via Smartphones are a viable approach to addressing supportive care accessibility issues while also integrating multidisciplinary approaches for improving HRQoL, few eHealth interventions have been developed that specifically target Hispanic breast cancer survivors (BCS). This manuscript describes the methodology of a multi-site, randomized controlled behavioral trial investigating the feasibility and preliminary efficacy of a Smartphone application aimed at improving HRQoL and cancer-specific distress among Hispanic BCS. Participants will be randomized to receive the intervention application, My Guide (psychoeducation & self-management program), or the health education control condition application, My Health (health education), for six weeks. All participants will also receive weekly telecoaching to enhance adherence to both control and intervention conditions. We will measure the study's primary outcomes, general and disease-specific HRQoL and cancer-specific distress, at three time points: prior to, immediately after the intervention, and eight weeks after initial application use. My Guide may have the potential to improve HRQoL, and to address issues of limited access to supportive care among Hispanic women recovering from breast cancer treatment.

Designing an mHealth application to bridge health disparities in Latina breast cancer survivors: a community-supported design approach.

Latina breast cancer patients in the USA report significantly worse cancer-related symptom burden and health-related quality of life than non-Hispanic whites. However, health literacy (e.g. knowledge about cancer, coping skills and communication) has been found to improve quality of life. In this paper, we present a case study of the methodology used to design Mi Guía (My Guide), a mobile application that aims to improve symptom burden and health-related quality of life among Hispanic women who have completed active treatment for breast cancer by increasing their health literacy. We developed a community-supported approach to building the application, which involved: (1) eliciting feedback from community leaders such as support group organizers and facilitators who are bilingual in Spanish and English, prioritize patients' preferences and best interests and have a unique knowledge of the women and their needs;(2) conducting a formal evaluation of design principles based on previous interaction design research and user responses;(3) incorporating feedback from potential future users. In this paper, we discuss our methodology, and the challenges and benefits of this approach. We believe that future studies that aim to develop mobile technologies for underserved populations may benefit from a community-supported approach to design.
