Pilot Study of a Mobile Phone Chatbot for Medication Adherence and Toxicity Management Among Patients With GI Cancers on Capecitabine.

PURPOSE: Capecitabine is an oral chemotherapy used to treat many gastrointestinal cancers. Its complex dosing and narrow therapeutic index make medication adherence and toxicity management crucial for quality care. METHODS: We conducted a pilot study of PENNY-GI, a mobile phone text messaging-based chatbot that leverages algorithmic surveys and natural language processing to promote medication adherence and toxicity management among patients with gastrointestinal cancers on capecitabine. Eligibility initially included all capecitabine-containing regimens but was subsequently restricted to capecitabine monotherapy because of challenges in integrating PENNY-GI with radiation and intravenous chemotherapy schedules. We used design thinking principles and real-time data on safety, accuracy, and usefulness to make iterative refinements to PENNY-GI with the goal of minimizing the proportion of text messaging exchanges with incorrect medication or symptom management recommendations. All patients were invited to participate in structured exit interviews to provide feedback on PENNY-GI. RESULTS: We enrolled 40 patients (median age 64.5 years, 52.5% male, 62.5% White, 55.0% with colorectal cancer, 50.0% on capecitabine monotherapy). We identified 284 of 3,895 (7.3%) medication-related and 13 of 527 (2.5%) symptom-related text messaging exchanges with incorrect recommendations. In exit interviews with 24 patients, participants reported finding the medication reminders reliable and user-friendly, but the symptom management tool was too simplistic to be helpful. CONCLUSION: Although PENNY-GI provided accurate recommendations in >90% of text messaging exchanges, we identified multiple limitations with respect to the intervention's generalizability, usefulness, and scalability. Lessons from this pilot study should inform future efforts to develop and implement digital health interventions in oncology.

Health behaviors among head and neck cancer survivors.

PURPOSE: To determine to what extent head and neck cancer (HNC) survivors participate in health behaviors (HBs) recommended by the National Cancer Center Network (NCCN®). METHODS: Participants identified through the tumor registries at the Abramson Cancer Center (ACC), University of Pennsylvania and affiliated sites. Eligibility: (a) diagnosis and treatment HNC; (b) aged 18 to 70 years; (c) ≥ 1-year post-diagnosis; (d) human papillomavirus (HPV) status confirmed; (e) ability to understand written English. Potential participants received an explanation of the study, informed consent, self-reported questionnaire, and self-addressed stamped envelope. RESULTS: 451 individuals eligible, 102 (23%) agreed to participate, HPV positive (74%). Current smoking rare (7%), historical use common (48%). Current alcohol use common (65%), average 2.1 drinks/day, 12 days/month. 22% binge drank with an average of 3.5 binge-drinking sessions per month. Nutritional behavior mean 7.1 (range 0-16), lower scores indicating better nutrition. Body mass index (BMI) 59% overweight/obese. Adequate aerobic exercise 59%, adequate strength and flexibility 64%. Leisure time activity, 18% sedentary, 19% moderately active, 64% active. All participants reported having a primary care physician, 92% seen in the previous 12 months. CONCLUSIONS: Most HNC survivors participated in some HBs. Current smoking rarely reported, binge drinking and high BMI most common negative HBs. Opportunities remain to improve dietary and exercise behaviors. IMPLICATIONS FOR CANCER SURVIVORS: The NCCN® has outlined HBs that decrease likelihood of cancer survivors developing comorbidities that could impact overall survival. It is incumbent on healthcare providers to educate and encourage cancer survivors to participate in these HBs.

Lower abdominal and pelvic radiation and testicular germ cell tumor risk.

BACKGROUND: Testicular germ cell tumor (TGCT) incidence has increased in recent decades along with the use and dose of diagnostic radiation. Here we examine the association between reported exposure to diagnostic radiation and TGCT risk. METHODS: We conducted a case-control study of men with and without TGCT recruited from hospital- and population-based settings. Participants reported on exposures to 1) x-ray or CT below the waist and 2) lower GI series or barium enema, which consists of a series of x-rays of the colon. We also derived a combined measure of exposure. We used logistic regression to determine the risk of developing TGCT according to categories of exposures (0, 1-2, or ≥3 exposures) and age at first exposure, adjusting for age, year of birth, race, county, body mass index at diagnosis, family history of TGCT, and personal history of cryptorchidism. RESULTS: There were 315 men with TGCT and 931 men without TGCT in our study. Compared to no exposures, risk of TGCT was significantly elevated among those reporting at least three exposures to x-ray or CT (OR≥3 exposures, 1.78; 95% CI, 1.15-2.76; p = 0.010), lower GI series or barium enema (OR≥3 exposures, 4.58; 95% CI, 2.39-8.76; p<0.001), and the combined exposure variable (OR≥3 exposures, 1.59; 95% CI, 1.05-2.42; p = 0.029). The risk of TGCT was elevated for those exposed to diagnostic radiation at age 0-10 years, compared to those first exposed at age 18 years or later, although this association did not reach statistical significance (OR, 2.00; 95% CI, 0.91-4.42; p = 0.086). CONCLUSIONS: Exposure to diagnostic radiation below the waist may increase TGCT risk. If these results are validated, efforts to reduce diagnostic radiation doses to the testes should be prioritized.

Adult survivors of childhood cancer: the medical and psychosocial late effects of cancer treatment and the impact on sexual and reproductive health.

INTRODUCTION: There are over 13 million cancer survivors in the United States, which constitutes 3-4% of the U.S. population. According to the Surveillance Epidemiology and End Results program (SEER) data the 5-year overall survival rate for children diagnosed with cancer between ages 0-19 is 83.1%, and 2/3 of childhood cancer survivors will experience at least one late effect of treatment. AIM: To provide a brief overview of the medical and psychosocial effects of cancer treatments in survivors of childhood cancer with a focus on sexual and reproductive health issues in this population. METHODS: The development of a manuscript from a presentation at the Annual Society of Sexual Medicine meeting. An overview of long-term and late effects of treatment experienced by young adult cancer survivors was presented. MAIN OUTCOME MEASURE: This manuscript is based on a presentation that reviewed the medical and psychosocial literature, consensus statements of professional groups, and clinical observations. RESULTS: Cancer and cancer treatments have both direct and indirect effects of physiological, psychological, and interpersonal factors that can negatively impact the health and well-being of cancer survivors including sexual and reproductive function and satisfaction. CONCLUSIONS: Cancer, its management, and the resulting late effects must be explored and understood by providers caring for childhood cancer survivors so that educational, psychological, pharmacologic, as well as preventive interventions can be implemented with this population.

How confident are young adult cancer survivors in managing their survivorship care? A report from the LIVESTRONG™ Survivorship Center of Excellence Network.

INTRODUCTION: This study examined the association between sociodemographic, cancer treatment, and care delivery factors on young adult cancer survivors' confidence in managing their survivorship care. METHODS: Survivors aged 18-39 years (n = 376) recruited from the LIVESTRONG™ Survivorship Center of Excellence Network sites completed a survey assessing self-reported receipt of survivorship care planning, expectations of their providers, and confidence in managing their survivorship care. Multivariate logistic regression identified characteristics of those reporting low confidence in managing their survivorship care. RESULTS: Mean age was 28 years; mean interval from diagnosis was 9 ± 8 years. Seventy-one percent reported currently attending an oncology survivorship clinic. Regarding survivorship care planning, 33% did not have copies of their cancer-related medical records, 48% did not have a treatment summary, and 55% had not received a survivorship care plan. Seventy percent identified the oncologist as the most important health care provider for decisions regarding test and treatment decisions while 10% reported using a "shared-care model" involving both primary care providers and oncologists. Forty-one percent were classified as having low confidence in managing survivorship care. In multivariate analysis, low confidence was associated with non-white ethnicity and lack of a survivorship care plan (both p < 0.05). DISCUSSION/CONCLUSIONS: Findings suggest that provision of survivorship care plans for young adult cancer survivors can be used to improve confidence in managing survivorship care, particularly for ethnic minorities. IMPLICATIONS FOR CANCER SURVIVORS: Survivors should consider advocating for receipt of a survivorship care plan as it may facilitate confidence as a consumer of survivorship care.

Adult cancer survivorship: evolution, research, and planning care.

Increases in the number of adult cancer survivors and other issues have forced the oncology community to examine, evaluate, and alter the cancer care paradigm. Pediatric oncologists are grappling with the task of transitioning a growing population of adult survivors of childhood cancer to adult medicine, while oncologists caring for adult cancer survivors are seeking models of follow-up care that are acceptable to patients and providers. Workforce and access-to-care issues suggest that primary care providers will see more cancer survivors in their practices across time, although it is unclear how prepared they are for this task. Translational research is needed to develop evidence-based clinical care and survivorship care plans. A broad picture of the evolving field of adult cancer survivorship is presented. The recent focus on young adult survivors of childhood cancer, an overview of translational research needed to inform the physical and psychosocial care of cancer survivors, and the roles of primary and specialty care providers managing this population is examined. Finally, an overview of evolving treatment summary and care plan initiatives is presented.

Feasibility trial of electroacupuncture for aromatase inhibitor--related arthralgia in breast cancer survivors.

BACKGROUND: Arthralgia affects postmenopausal women receiving aromatase inhibitors (AIs) for breast cancer. Given the existing evidence for electroacupuncture (EA) for treatment of osteoarthritis in the general population, this study aims to establish the feasibility of studying EA for treating AI-related arthralgia. PATIENTS AND METHODS: Postmenopausal women with stage I-III breast cancer who reported AI-related arthralgia were enrolled in a single-arm feasibility trial. EA was provided twice a week for 2 weeks followed by 6 weekly treatments. The protocol was based on Chinese medicine diagnosis of "Bi" syndrome with electrostimulation of needles around the painful joint(s). Pain severity of the modified Brief Pain Inventory was used as the primary outcome. Joint stiffness, joint interference, and Patient Global Impression of Change (PGIC) were secondary outcomes. Paired t tests were used for analysis. RESULTS: Twelve women were enrolled and all provided data for analysis. From baseline to the end of intervention, patients reported reduction in pain severity (from 5.3 to 1.9), stiffness (from 6.9 to 2.4), and joint symptom interference (from 4.7 to 0.8), all P < .001; 11/12 considered joint symptoms "very much better" based on the PGIC. Subjects also reported significant decrease in fatigue (from 4.4 to 1.9, P = .005) and anxiety (from 7.1 to 4.8, P = .01). No infection or development or worsening of lymphedema was observed. CONCLUSION: Preliminary data establish the feasibility of recruitment and acceptance as well as promising preliminary safety and effectiveness. A randomized controlled trial is warranted to establish the efficacy of EA for AI-related arthralgia in breast cancer survivors.
