Breast cancer is the most common cancer among Canadian women, bringing complex demands for timely decision-making, coordination of multidisciplinary care, and efficient communication between patients and providers. The increasing reliance on fragmented and noninteroperable health information systems exacerbates workflow and documentation burdens, leading to inefficiencies and gaps in continuity of care. While nurse navigation programs partially bridge these gaps, most digital platforms remain poorly integrated into provider workflows, requiring manual tracking, which results in duplicated effort and reduced efficiency. Our team developed “MyJourney” at North York General Hospital (NYGH) in Ontario. It is a digital navigation platform that supports breast cancer care throughout the entire continuum, from diagnosis to survivorship.

Consumer smartwatches offer potential for continuous monitoring of physical activity during childhood cancer treatment. However, their validity for measuring step count and heart rate in this population has not been established.

Endocrine therapy is a fundamental treatment for hormone receptor–positive breast cancer. However, treatment-related symptoms may lead to poor adherence and premature discontinuation, adversely affecting clinical outcomes. eHealth technology interventions have been widely applied as potential tools to support patient education, symptom management, and adherence.

Despite the human papillomavirus (HPV) vaccine being available to males for the past 12 years, adolescent males continue to lag in HPV vaccine uptake due to a variety of factors. With the ubiquitous nature of social media use among this population, further research is needed to improve HPV vaccine confidence among young adolescent males using these platforms.

With increasing numbers of survivors with cancer, the importance of patient-centered information provision and communication to alleviate psychological burdens, such as anxiety and depression, is growing. However, substantial individual differences exist in patients with cancer information–seeking behaviors and use of support services, and few studies have comprehensively examined cognitive and psychological factors such as treatment status, sex, trust in information sources, and patient-provider relationships.

Despite a global decline in the incidence of gastric cancer (GC), the number of cases diagnosed among younger individuals continues to increase. Several studies have been conducted to develop predictive models of mortality in patients with GC.

Consumer fitness tracker devices offer scalable opportunities to monitor real-world behavior and support health in cancer survivorship. However, adoption and sustained use outside structured research settings remain incompletely characterized, limiting their integration into survivorship care.

Approximately 80% of breast cancers are estrogen receptor positive, and following initial tumor treatment, patients are prescribed hormone therapy (HT) drugs (tamoxifen, letrozole, anastrozole, and exemestane) for 5-10 years. These drugs are known to cause several side effects. Additionally, a small number of studies have identified that changing medication brands (generics) can negatively affect patients’ side effects, attitudes, and acceptance of HT. However, no effective intervention currently exists to address patients’ concerns about generic switching.

Patients receiving systemic anticancer therapy (SACT) can deteriorate clinically between scheduled appointments; yet, acute oncology services often rely on reactive helplines with limited longitudinal symptom visibility.

Lung cancer is one of the most commonly diagnosed cancers worldwide and the leading cause of cancer-related mortality. Global studies have highlighted the importance of awareness of lung cancer signs and symptoms, as it influences health care seeking, diagnosis timing, and treatment outcomes. Despite the high prevalence of both lung cancer and smoking in Jordan, no studies have assessed lung cancer awareness among the Jordanian population. This study is the first in Jordan to reveal the levels of awareness of lung cancer signs and symptoms, risk factors, and screening and to identify factors associated with the awareness level.

About 4 in 10 people in Sweden get cancer during their lifetime, and approximately half of them will be diagnosed during their working life. As cancer survival rates improve, a growing number of individuals face challenges in returning to work following treatment. This increases the demand for effective return-to-work (RTW) strategies. Despite existing rehabilitation frameworks, cancer survivors often encounter barriers to sustainable work reintegration.

Wearable devices are becoming more ubiquitous and are capable of capturing health-relevant information that patients may be interested in sharing with their providers. However, limited research has been conducted on oncology provider perspectives on how these data could be used to inform cancer care.
