RESUMEN
BACKGROUND: Due to unique technical challenges, effective peripheral blood stem cell collections (PBSCs) have not been consistently reported in patients weighing less than 5 kg. We describe three PBSCs performed in a 4.6-kg child undergoing myeloablative chemotherapy for high-grade glioma. STUDY DESIGN AND METHODS: A multidisciplinary group representing the clinical and apheresis teams adapted a PBSC protocol to accommodate the patient's size and collection targets. Special considerations included timing of the collection relative to chemotherapy, vascular access, strategies for monitoring adverse events during collection, and contingencies. RESULTS AND DISCUSSION: The patient underwent three PBSC procedures over 2 days due to suboptimal collection after the first two procedures. For procedure 1, a conservative inlet: anticoagulant (AC) ratio and AC infusion rate of 15 and 0.6 mL/min/L total blood volume (TBV) resulted in premature discontinuation due to clotting. A ratio of 8 and AC infusion rate of 1.5-1.7 mL/min/L TBV with subsequent titration to higher levels were adopted for the second and third procedures. These changes resulted in greater acid-citrate-dextrose exposure, that was managed by continuous calcium chloride infusion. There was no hypocalcemia, hypotension, or distress during any procedure. A total of 15 × 106 CD34+ cells/kg were collected. This retrospective review illustrates that PBSC can be safely undertaken in children weighing less than 5 kg.

Anti-PP1PK alloimmunization is rare given ubiquitous P1PK expression. Prevention of recurrent miscarriages and hemolytic disease of the fetus and newborn (HDFN) in pregnant individuals with anti-PP1PK antibodies has relied upon individual reports. Here, we demonstrate the successful management of maternal anti-PP1PK alloimmunization in a 23-year-old, G2P0010, with therapeutic plasma exchange (TPE), intravenous immunoglobulin (IVIG), and monitoring of anti-PP1Pk titers. Twice-weekly TPE (1.5 plasma volume [PV], 5% albumin replacement) with weekly titers and IVIG (1 g/kg) was initiated at 9 weeks of gestation (WG). The threshold titer was ≥16. Weekly middle cerebral artery-peak systolic velocities (MCA-PSV) for fetal anemia monitoring was initiated at 16 WG. PVs were adjusted throughout pregnancy based on treatment schedule, titers, and available albumin. Antigen-negative, ABO-compatible RBCs were obtained through the rare donor program and directed donation. An autologous blood autotransfusion system was reserved for delivery. Titers decreased from 128 to 8 by 10 WG. MCA-PSV remained stable. At 24 WG, TPE decreased to once weekly. After titers increased to 32, twice-weekly TPE resumed at 27 WG. Induction of labor was scheduled at 38 WG. Vaginal delivery of a 2950 g neonate (APGAR score: 9, 9) occurred without complication (Cord blood: 1+ IgG DAT; Anti-PP1Pk eluted). Newborn hemoglobin and bilirubin were unremarkable. Discharge occurred postpartum day 2. Anti-PP1Pk alloimmunization is rare but associated with recurrent miscarriages and HDFN. With multidisciplinary care, a successful pregnancy is possible with IVIG and TPE adjusted to PV and titers. We also propose a patient registry and comprehensive management plan.

BACKGROUND: An electronic Prospective Surveillance Model (ePSM) uses patient-reported outcomes to monitor symptoms along the cancer pathway for timely identification and treatment. Randomized controlled trials show that ePSMs can effectively manage treatment-related adverse effects. However, an understanding of optimal approaches for implementing these systems into routine cancer care is limited. This study aimed to identify barriers and facilitators prior to the implementation of an ePSM to inform the selection of implementation strategies. METHODS: A qualitative study using virtual focus groups and individual interviews was conducted with cancer survivors, oncology healthcare providers, and clinic leadership across four cancer centres in Canada. The Consolidated Framework for Implementation Research (CFIR) guided the interviews and analysis of barriers and facilitators based on five domains (intervention characteristics, individual characteristics, inner setting, outer setting, and process). RESULTS: We conducted 13 focus groups and nine individual interviews with 13 patient participants and 56 clinic staff. Of the 39 CFIR constructs, 18 were identified as relevant determinants to the implementation. The adaptability, relative advantage, and complexity of an ePSM emerged as key intervention-level factors that could influence implementation. Knowledge of the system was important at the individual level. Within the inner setting, major determinants were the potential fit of an ePSM with clinical workflows (compatibility) and the resources that could be dedicated to the implementation effort (readiness for implementation). In the outer setting, meeting the needs of patients and the availability of rehabilitation supports were key determinants. Engaging various stakeholders was critical at the process level. CONCLUSIONS: Improving the implementation of ePSMs in routine cancer care has the potential to facilitate early identification and management of treatment-related adverse effects, thereby improving quality of life. This study provides insight into important factors that may influence the implementation of an ePSM, which can be used to select appropriate implementation strategies to address these factors.

BACKGROUND: Prior to laboratory-based blood donor screening for Babesia, transfusion-transmitted babesiosis (TTB) was a leading infectious risk to the blood supply in the United States. CASE REPORT: A 30-year-old man with sickle cell disease (SCD) who had been on a chronic automated red cell exchange (RCE) regimen since childhood, presented approximately 2 months after an RCE, with fever, neck pain, and photophobia. Meningitis was excluded, and he was discharged. He presented again 2 days later with persistent fever, chills, headache, fatigue, and loss of appetite. RESULTS: On examination, the patient was febrile but hemodynamically stable. Intra-erythrocytic inclusions were identified on a peripheral blood smear (<0.5%). B. microti IgM and IgG titers were >1:320 (Reference <1:20) >1:1024 (Reference <1:64), respectively. B. microti was confirmed by nucleic acid testing. The patient lived in a Babesia endemic state but had no risk factors for tick-borne acquisition. Of the 65 units he received in the preceding 6 months, 58 had been screened for Babesia. One of the donors of the 7 untested units was B. microti seropositive (titer 1:128; Reference 1: 64). The donor was asymptomatic and resided in a state in which Babesia screening was not required. He reported traveling in the year before his donation. CONCLUSION: Although rare, TTB is still possible despite regional screening, underscoring the need for provider vigilance and education, especially in non-endemic areas. Patients with SCD are particularly vulnerable given their high frequency of transfusion and complex needs requiring blood procurement from states where Babesia screening is not mandatory.

PURPOSE OF REVIEW: This narrative review aims to offer a thorough summary of functional impairments commonly encountered by breast cancer survivors following mastectomy. Its objective is to discuss the factors influencing these impairments and explore diverse strategies for managing them. RECENT FINDINGS: Postmastectomy functional impairments can be grouped into three categories: neuromuscular, musculoskeletal, and lymphovascular. Neuromuscular issues include postmastectomy pain syndrome (PMPS) and phantom breast syndrome (PBS). Musculoskeletal problems encompass myofascial pain syndrome and adhesive capsulitis. Lymphovascular dysfunctions include lymphedema and axillary web syndrome (AWS). Factors such as age, surgical techniques, and adjuvant therapies influence the development of these functional impairments. Managing functional impairments requires a comprehensive approach involving physical therapy, pharmacologic therapy, exercise, and surgical treatment when indicated. It is important to identify the risk factors associated with these conditions to tailor interventions accordingly. The impact of breast reconstruction on these impairments remains uncertain, with mixed results reported in the literature.

PURPOSE: Exercise and social support are non-pharmacological strategies that improve health and wellbeing in women treated for breast cancer (WTBC). However, strategies to facilitate support and exercise in WTBC are typically resource intensive. The purpose of this study was to examine whether various forms of social support received from a matched peer were associated with increased exercise among WTBC. METHODS: A daily diary study was conducted to examine naturally occurring social support as it relates to daily exercise behavior. Forty-six WTBC were matched (23 pairs) and completed pre-screening survey assessing eligibility and baseline levels of exercise. Participants were given Fitbit devices to track physical activity behavior and completed daily surveys across 3 weeks assessing perceptions of exercise-related social support at fixed times at the end of each day. RESULTS: Mixed models accounting for day of study, baseline support, and baseline exercise levels revealed that higher levels of daily exercise-related tangible social support were associated with more daily steps (b = 506, SE = 143) and more light physical activity (LPA) minutes (b = 7.01, SE = 3.15). Informational social support was associated with higher moderate to vigorous physical activity (MVPA) minutes (b = 3.18, SE = 1.60). CONCLUSIONS: Overall, peer matching programs aimed at increasing exercise-related social support among WTBC might encourage exercise behaviors, especially among women who share exercise-specific information (e.g., benefits, type, activities).

BACKGROUND: Due to the national blood supply crisis caused by the COVID-19 pandemic, the American Society of Hematology proposed guidance to decrease blood utilization for sickle cell patients on chronic transfusion therapy (CTT). Little evidence exists to support the efficacy and safety of these blood conservation strategies. STUDY DESIGN AND METHODS: Through retrospective analysis, we sought to describe outcomes following implementation of these recommendations in 58 adult sickle cell patients on chronic exchange transfusions. The strategies employed included: relaxing the goal fraction of cells remaining (FCR) to 30%-50%, utilizing depletion exchanges in select patients, and transitioning select patients to monthly simple transfusions. We compared hemoglobin S%, hemoglobin values, and other laboratory parameters, acute care visits, and red blood cell usage during the first year of the COVID-19 pandemic to the year prior using Wilcoxon signed rank test. RESULTS: Of 53 patients who remained on chronic exchanges during the pandemic, use of depletion exchange increased (15%-23%) and FCR increased (34.9 [SD 4.7] vs. 37.6 [SD 4.5], p < .05). These changes resulted in 854 units conserved without clinically significant changes to pre-exchange laboratory parameters, including hemoglobin S%, or number of acute care presentations. In contrast, five patients who transitioned to predominantly simple transfusions, experienced difficulty maintaining hemoglobin S% less than 30 and worsening anemia. DISCUSSION: Our data suggest that in a blood shortage crisis, optimizing the exchange procedure itself may be the safest means of conserving blood in a population of adult patients with sickle cell disease.

BACKGROUND: Breastfeeding practices are determined by complex multilevel factors. This study assessed pregnant women's knowledge of breastfeeding and intention to breastfeed and investigated modifiable predictors for breastfeeding status (exclusive or any breastfeeding) and duration at 6 and 12 months postpartum. MATERIALS AND METHODS: Longitudinal data were extracted from a trial in Sydney, Australia, 2017-19. Women (n = 1155) were recruited from antenatal clinics and followed up for telephone interviews at baseline (third trimester), then at 6 and 12 months postpartum. Data collected included mothers' demographics; knowledge of breastfeeding and intention to breastfeed; work status; support from caregivers; breastfeeding environment; breastfeeding status and duration. Multiple logistic and Cox regression models were built to identify predictors for breastfeeding. RESULTS: At baseline, most mothers knew the recommendation to exclusively breastfeed until 6 months (66%) and the benefits (65%). The modifiable predictors for breastfeeding duration at 12 months included the following: mothers' knowledge of the recommendation (adjusted hazard ratio (AHR) 0.73, 95% confidence interval (CI) 0.60-0.90) and the benefits of exclusive breastfeeding (AHR 0.68, 95% CI 0.55-0.82), intention to meet the recommendation (AHR 0.76, 95% CI 0.63-0.93), and intention to breastfeed for two years (AHR 0.38, 95% CI 0.27-0.52) measured at baseline; mothers not working or studying (AHR 0.70, 95% CI 0.55-0.89), having support from other caregivers (AHR 0.64, 95% CI 0.43-0.96), and having breastfeeding women around (AHR 0.80, 95% CI 0.65-0.98) measured at 6 months. CONCLUSIONS: Support for women to meet the breastfeeding recommendations should commence during pregnancy and focus on breastfeeding education and enabling environments.

BACKGROUND: Prostate cancer survivors (PCS) experience long-term side effects beyond treatment such as fatigue, depression and anxiety. Quality and engaging supportive care programs are needed to reduce these chronic and debilitating effects. Independent of physical activity (PA), high volumes of sedentary behavior (SB) are associated with chronic disease-related risk factors and poorer cancer-specific quality of life (QoL). Simultaneously increasing PA and decreasing SB may be an effective health promotion strategy. Given that PCS may face several barriers to engaging in supervised programs, there is a need to develop and assess the efficacy of interventions that employ distance-based approaches for behavior change. The primary aim of this study is to determine the effects of a 12-week intervention (Fitbit + behavioral counselling) vs. Fitbit-only control group in reducing SB among PCS. Secondary outcomes include light-intensity PA, QoL, motivational outcomes, and patient satisfaction. METHODS: This two-armed, randomized controlled trial will recruit inactive PCS (stage I-IV) across Canada who self-report engaging in >8 hours/day of SB. Participants will be randomized to the intervention (n=60; Fitbit and behavioral support) or active control group (n=60; Fitbit-only). The intervention consists of the use of a Fitbit and a series of six behavioral support sessions (two group, four individual) to aid PCS in gradually replacing SB with light-intensity PA by increasing their daily step counts to 3,000 steps above their baseline values. The Fitbit-only control condition will receive a Fitbit and public health PA resources. The primary outcome is change in SB measured objectively using activPAL inclinometers. All secondary outcomes will be measured via self-report, except for PA which will be measuring using Fitbits. Data will be collected at baseline, post-intervention, and at 6-month post-intervention. DISCUSSION: Reducing SB and increasing light-intensity PA plays an important, yet often undervalued role in the health and well-being of PCS. This study will create a unique distance-based platform that can be used by clinical and community-based organizations as a low-cost, supportive care tool to improve health outcomes for PCS.

To examine associations of physical activity (PA) and sedentary time (SED) with quality of life (QoL) in men on androgen deprivation therapy (ADT) for prostate cancer. A pooled analysis of 106 men on ADT was conducted. PA and SED were assessed using accelerometers. The Functional Assessment of Cancer Therapy (FACT) was used to assess self-reported QoL. Quantile regression examined the associations of QoL with PA and SED. Total time spent in SED was positively associated with FACT-General at the 50th (p = 0.010) and 75th percentile (p = 0.022). SED in ≥ 30-min bouts was inversely associated with FACT-General at the 50th (p = 0.025) and 75th percentile (p = 0.029). Breaks in SED were positively associated with physical well-being at the 75th percentile (p = 0.004). Light-intensity PA was positively associated with FACT-Prostate at the 25th percentile (p = 0.020). SED and PA were associated with QoL outcomes, but time in each varied across men reporting the poorest QoL compared to those in the highest QoL distributions.

PURPOSE: Examine feasibility and acceptability of a group-mediated cognitive-behavioral (GMCB) intervention targeting planned, self-managed physical activity (PA). DESIGN: Sequential mixed methods, single arm pre-/post-test design with a 4-week follow-up. PARTICIPANTS: Post-treatment gynecologic cancer survivors. METHODS: Participants attended 8 weekly facilitator-led group sessions and completed assessments at baseline, post-intervention and follow-up. Feasibility was assessed by recruitment rate, retention rate, capture of outcomes, intervention usability and intervention fidelity. Acceptability was examined via qualitative interviews. Preliminary estimates of intervention effectiveness (PA, PA social cognitions and sleep) were collected. FINDINGS: 355 participants were approached and 38 consented. Twenty took part in the study and 17 (85%) completed the intervention. Thematic content analysis revealed positive group experiences. Cognitive-behavioral strategies were beneficial. Goal-setting and shared cancer recovery experience facilitated connection among group members. IMPLICATIONS: Program acceptability was high among a diverse sample of gynecologic cancer survivors and delivery of the program is feasible to this group of gynecologic cancer survivors. Recruitment challenges were present but study retention was high.

BACKGROUND: Adults with sickle cell disease (SCD) on chronic transfusion therapy are exposed to a large volume of blood products, thus increasing their risk of transfusion-associated human immunodeficiency virus (HIV), hepatitis C (HCV), and hepatitis B (HBV). METHODS: We performed a systematic chart review of chronically transfused SCD subjects at the Johns Hopkins Sickle Cell Center for Adults between October 2014 and September 2019 to determine our Center's adherence to the 2014 National Heart, Lung and Blood Institute (NHLBI) SCD guidelines for annual screening for Transfusion Transmitted infections (TTI) and assessed HBV immunity and HBV vaccination rates. RESULTS: The study included 85 subjects with a median age of 34 years (23-63); 52% were female. No subject received annual screening; 68 subjects (80%) were screened for HIV, 60 subjects (71%) for HCV and 53 subjects (62%) for HBV infections at least once in the study period. Of those screened, one patient was newly diagnosed with HCV infection, and none with HIV or HBV infection. Among 31 subjects tested for anti-Hepatitis B surface antibody, 16 subjects (52%) tested negative. Nineteen (20%) subjects had HBV vaccination documented. CONCLUSIONS: Low adherence to the NHLBI TTI screening guidelines, especially for HBV, highlights the resource intensiveness of this patient population. The low rates of anti-Hepatitis B surface antibody positivity highlight the need to confirm vaccination, provide boosters as indicated, and investigate the adults with SCD's immune response to HBV vaccination.

PURPOSE: Home-based exercise interventions offer many health benefits; however, the environments that constitute home-based exercise are not well-understood. The purpose of this study was to explore what constitutes the "home" for cancer survivors engaging in home-based exercise and identify factors of the environment that may impact exercise participation. METHODS: We conducted a qualitative exploratory study of cancer survivors receiving a home-based exercise prescription to manage their cancer-related impairments. Semi-structured interviews included photo elicitation to actively involve participants in the interview process and provide opportunities to visually "observe" environments utilized for home-based exercise. RESULTS: Sixteen participants were interviewed (n = 11 women, median age = 53.5, range = 26-74 years) and three themes emerged: (1) reasons for participating in a home-based exercise program; (2) physical environmental influences and preferences; and (3) social environmental influences and preferences. The ability to self-manage exercise and accommodate competing demands, having access to exercise facilities, feeling comfortable exercising without qualified supervision, and a desire for autonomy were reasons home-based exercise programs were preferred. Participants reported that the physical environment influenced their experience with home-based exercise and sub-themes related to a dynamic environment, indoor and outdoor characteristics, and aesthetics were identified. The social environment, with sub-themes associated with the presence of people, social climate, exercise modeling, connection, and exercise support, also related to exercise behavior. CONCLUSION: The findings highlight the influence of the physical and social environment on exercise prescription engagement. They further indicate the need for exercise professionals to consider the environment for exercise when delivering home-based exercise interventions.

OBJECTIVE: To describe the adaptations made to implement virtual cancer rehabilitation at the onset of the coronavirus disease 2019 pandemic, as well as understand the experiences of patients and providers adapting to virtual care. DESIGN: Multimethod study. SETTING: Cancer center. PARTICIPANTS: A total of 1968 virtual patient visits were completed during the study period. Adult survivors of cancer (n=12) and oncology health care providers (n=12) participated in semi-structured interviews. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Framework-driven categorization of program modifications, qualitative interviews with patients and providers, and a comparison of process outcomes with the previous 90 days of in-person care via referrals, completed visits and attendance, method of delivery, weekly capacities, and wait times. RESULTS: The majority of program visits could be adapted to virtual delivery, with format, setting, and content modifications. Virtual care demonstrated an increase or maintenance in the number of completed visits by appointment type compared with in-person care, with attendance ranging from 80%-93%. For most appointment types, capacities increased, whereas wait times decreased slightly. Overall, 168 patients (11% of all assessments and follow-ups) assessed virtually were identified by providers as requiring an in-person appointment because of reassessment of musculoskeletal and/or neurologic impairment (n=109, 65%) and lymphedema (n=59, 35%). The interviews (n=24) revealed that virtual care was an acceptable alternative in some circumstances, with the ability to (1) increase access to care; (2) provide a sense of reassurance during a time of isolation; and (3) provide confidence in learning skills to self-manage impairments. CONCLUSIONS: Many appointments can be successfully adapted to virtual formats to deliver cancer rehabilitation programming. Based on our findings, we provide practical recommendations that can be implemented by providers and programs to facilitate the adoption and delivery of virtual care.

OBJECTIVE: To examine health behaviours in bladder cancer survivors including physical activity (PA), body mass index, diet quality, smoking and alcohol consumption, and to explore their relationship with health-related quality of life (HRQoL). SUBJECTS/PATIENTS AND METHODS: Cross-sectional questionnaire packages were distributed to bladder cancer survivors (muscle-invasive bladder cancer [MIBC] and non-muscle-invasive bladder cancer [NMIBC]) aged >18 years, and proficient in English. Lifestyle behaviours were measured using established measures/questions, and reported using descriptive statistics. HRQoL was assessed using the validated Bladder Utility Symptom Scale, and its association with lifestyle behaviours was evaluated using analysis of covariance (ancova) and multivariate regression analyses. RESULTS: A total of 586 participants completed the questionnaire (52% response rate). The mean (SD) age was 67.3 (10.2) years, and 68% were male. PA guidelines were met by 20% (n = 117) and 22.7% (n = 133) met dietary guidelines. In all, 60.9% (n = 357) were overweight/obese, and the vast majority met alcohol recommendations (n = 521, 92.5%) and were current non-smokers (n = 535, 91.0%). Health behaviours did not differ between MIBC and NMIBC, and cancer treatment stages. Sufficient PA, healthy diet, and non-smoking were significantly associated with HRQoL, and the number of health behaviours participants engaged in was positively associated with HRQoL (P < 0.001). CONCLUSION: Bladder cancer survivors are not meeting guidelines for important lifestyle behaviours that may improve their overall HRQoL. Future research should investigate the impact of behavioural and educational interventions for health behaviours on HRQoL in this population.

PURPOSE: Aerobic exercise prescriptions in clinical populations commonly involve target intensities based on cardiopulmonary exercise tests (CPET). CPETs are often discontinued prior to a patient achieving true maximum oxygen consumption (VO2 max) which can adversely affect exercise dose and efficacy monitoring; however, reasons for early discontinuation are poorly reported. Accordingly, we explored the CPET termination reasons in persons with cancer participating in exercise intervention studies. METHODS: This study comprised of an exploratory, descriptive analysis of retrospective CPET data (VO2 and anaerobic threshold) and termination reasons in a convenience sample of people with cancer participating in exercise intervention studies in a single laboratory. CPETs were standardized using the modified Bruce treadmill protocol with expired gas collection and analysis using a metabolic cart. VO2 max was considered "met" when participants demonstrated (a) oxygen consumption plateau or (b) two of the following criteria: rating of perceived exertion ≥ 9/10, respiratory exchange ratio ≥ 1.15, and/or heart rate of 95% of age-predicted maximum. The frequency and distribution of reasons for test termination relative to the number of CPET exposures for the participants were reported. RESULTS: Forty-four participants engaged in exercise studies between February 2016 and March 2018 provided data for the analysis. Participants completed up to three CPETs during this period (total of 78 CPETs in the current analysis). Eighty-six percent of all CPETs were terminated prior to achieving VO2 max verification criteria and no tests resulted in an oxygen consumption plateau. For those that did not demonstrate achievement of VO2 max verification criteria, reasons for discontinuation were distributed as follows: equipment discomfort-49%, volitional peak-36%, and physical discomfort-14.9%. For those who met VO2 max criteria, volitional peak was the most common reason for test termination (45.5%), followed by physical discomfort (36.4%), and equipment discomfort (18.2%). CONCLUSIONS: In our sample of cancer survivors, VO2 max criteria were infrequently met with equipment discomfort being a primary reason for participant-driven test termination. Protocol and equipment considerations are necessary for interpretation and application of CPET findings in clinical practice.

BACKGROUND: The literature reflects considerable heterogeneity in what constitutes home-based exercise interventions. The variability for where and what "home-based" exercise can represent challenges interpretation of findings and appropriate advocacy, referral, or development of these models of care. Therefore, the objective of this review was to provide a comprehensive summary of how home-based exercise is defined and reported in the literature and summarize the range of supportive elements utilized in home-based exercise trials. METHODS: We followed methodology for scoping reviews. Relevant research databases were searched from inception to March 2019. Two reviewers independently screened articles to determine eligibility and extracted terminology used to describe home-based exercise and intervention details for intervention delivery. RESULTS: Of the 9432 records identified, 229 articles met inclusion criteria. Across the literature, exercise interventions were described as home-based if they were completed at-home, outdoors in the neighbourhood, and in community facilities; or in self-selected environments; or if they were unsupervised. Supportive elements for home-based models ranged with respect to the amount of supervision and resources utilized, including the provision of print materials, exercise equipment, telephone support, home visits, and technology. CONCLUSIONS: This review provides a comprehensive summary of strategies previously utilized to deliver home-based exercise interventions in oncology, along with the various definitions of the home-based environment for exercise reported by researchers. Specific recommendations to improve the prescription and reporting of home-based exercise interventions are provided in order to facilitate the delivery, evaluation, and translation of findings into clinical practice.

PURPOSE: Adolescents and young adults (AYA) with cancer are increasingly using the internet and social media (SM) for cancer-related information. AYA face specific challenges and thus require tailored resources that meet their needs. We describe the internet and SM preferences of AYA related to their cancer information seeking behaviors and their preferences for a future resource compared to middle-aged adults (MAA). METHODS: Cancer patients completed a cross-sectional survey related to their internet and SM usage, cancer information, and preferences for future resources. Chi-square tests were used to compare AYA and MAA. RESULTS: The mean (±SD) age in the AYA group was 30±6.1 years (n = 129); in MAA 55±6.7 years (n = 157). In general, AYA preferred internet sites over SM platforms for cancer-related information and prefer a website platform over a SM platform for a new resource. Few AYA were aware of hospital-based AYA-specific resources. MAA were less likely to use SM compared with AYA (13% vs 4%, p = 0.01); however, websites and SM platforms that were used were similar between the 2 groups. Participants endorsed having already researched certain topics - yet, these were also those desired in a new resource. Compared to MAA, AYA sought more information on diet/nutrition, physical activity, exercise/fitness, fertility, sexual health, and body image (all p values < 0.05). CONCLUSION: AYA and MAA use similar resources on the internet and SM, but AYA sought information related to specific needs. Development of future resources should focus on an internet-based platform rather than a SM platform, coupled with promoting awareness of the resource.

BACKGROUND: Smoking cessation is an integral part of cancer survivorship. To help improve survivorship education, clinicians need an understanding of patient awareness of the harms of continued smoking. METHODS: Cancer survivors from Princess Margaret Cancer Centre (Toronto, ON) were surveyed on their awareness of the harms of continued smoking on cancer-related outcomes. Multivariable logistic regression models assessed factors associated with awareness and whether awareness was associated with subsequent cessation among smokers at diagnosis. RESULTS: Among 1118 patients, 23% were current smokers pre-diagnosis and 54% subsequently quit; 25% had lung and 30% head and neck cancers. Many patients reported being unaware that continued smoking results in greater cancer surgical complications (53%), increased radiation side effects (62%), decreased quality of life during chemotherapy (51%), decreased chemotherapy or radiation efficacy (57%), increased risk of death (40%), and increased development of second primaries (38%). Being a current smoker was associated with greater lack of awareness of some of these smoking harms (aORs = 1.53-2.20, P < 0.001-0.02), as was exposure to any second-hand smoke (aORs = 1.45-1.53, P = 0.006-0.04) and being diagnosed with early stage cancer (aORs = 1.38-2.31, P < 0.001-0.06). Among current smokers, those with fewer pack-years, being treated for cure, or had a non-tobacco-related cancer were more likely unaware. Awareness that continued tobacco use worsen quality of life after chemotherapy was associated with subsequent cessation (aOR = 2.26, P = 0.006). CONCLUSIONS: Many cancer survivors are unaware that continued smoking can negatively impact cancer-related outcomes. The impact of educating patients about the potential harms of continued smoking when discussing treatment plans should be further evaluated.

BACKGROUND: National and international bodies acknowledge the benefit of exercise for people with cancer, yet limited accessibility to related programing remains. Given their involvement in managing the disease, cancer centers can play a central role in delivering exercise-oncology services. The authors developed and implemented a clinically integrated exercise-oncology program at a major cancer center and evaluated its effectiveness and participant experience. METHODS: A hospital-based program with prescribed at-home exercise was developed and accepted referrals over a 42-month period (3.5 years). Implementation was conducted in 2 phases: a pilot phase for women with breast cancer and men with genitourinary cancer and a roll-out phase for all patients with cancer. Enrolled patients were assessed and received an exercise prescription as well as a program manual, resistance bands, and a stability ball from a kinesiologist. Program participation and effectiveness were evaluated up to 48 weeks after the baseline assessment using intention-to-treat analyses. Participants in the roll-out phase were asked to complete a program experience questionnaire at the completion of the 48-week follow-up. RESULTS: In total, 112 participants enrolled in the pilot, and 150 enrolled in the roll-out phase. Program attrition to 48 weeks was 48% and 65% in the pilot and roll-out phases, respectively. In participants who consented to research evaluation of their performance, objective and patient-reported measures of functional capacity improved significantly from baseline in both phases. Participants were highly satisfied with the program. CONCLUSIONS: Despite significant drop-out to program endpoints, our cancer-exercise program demonstrated clinically relevant improvement in functional outcomes and was highly appreciated by participants.
