Unveiling breast cancer risk profiles: a survival clustering analysis empowered by an online web application

Aim: To develop a shiny app for doctors to investigate breast cancer treatments through a new approach by incorporating unsupervised clustering and survival information. Materials & methods: Analysis is based on the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) dataset, which contains 1726 subjects and 22 variables. Cox regression was used to identify survival risk factors for K-means clustering. Logrank tests and C-statistics were compared across different cluster numbers and Kaplan-Meier plots were presented. Results & conclusion: Our study fills an existing void by introducing a unique combination of unsupervised learning techniques and survival information on the clinician side, demonstrating the potential of survival clustering as a valuable tool in uncovering hidden structures based on distinct risk profiles.

Association between sleep quality, anxiety and depression among Korean breast cancer survivors

AIM

This study aimed to examine the sleep pattern of breast cancer survivors and anxiety and depression associated with sleep quality to provide evidence-based information for the development of interventions to improve sleep disorders in these survivors.

DESIGN

A cross-sectional study.

METHODS

The subjects were 266 breast cancer survivors in South Korea. Structured questionnaires regarding sleep quality, anxiety and depression were used. The data were analysed using t test, ANOVA and multiple regression analysis.

RESULTS

Sleep duration and sleep disturbance were found to affect anxiety, whereas sleep latency and subjective sleep quality were found to affect depression. These results suggest that various factors affecting sleep quality should be considered when providing care for anxiety and depression in breast cancer survivors.

Factors Influencing Supportive Care Needs of Colorectal Cancer Survivors

PURPOSE

There is an increasing number of colorectal cancer survivors in South Korea. However, no research has identified supportive care needs of survivors of colorectal cancer in South Korea. Thus, the purpose of this study was to determine the level of supportive care needs and effects of emotional state and quality of life (QoL) on supportive care needs of colorectal cancer survivors.

METHODS

This cross-sectional study was conducted among 115 survivors of colorectal cancer in South Korean who had primary treatment of surgery for colorectal cancer. Data were collected from April to September 2016. Participants responded to self-reported questionnaires assessing supportive care needs, emotional state (Hospital Anxiety and Depression Scale), and QoL (Functional Assessment of Cancer Therapy-Colorectal scale).

RESULTS

The overall score of supportive care needs for colorectal cancer survivors was 1.22 ± 0.61 (full score: 3 points), with health care staff and social support needs garnering highest scores. Approximately, 20.0% and 21.7% of patients had anxiety and depression, respectively. The mean QoL score was 2.90 ± 0.53, with social and family status having the lowest QoL score. Multiple regression analysis showed that both the period after treatment and anxiety significantly influenced supportive care needs.

CONCLUSION

Appropriate interventions should be used immediately after completion of treatment to help reduce anxiety and meet supportive care needs of colorectal cancer survivors.

The psychosocial determinants of quality of life in breast cancer survivors: a scoping review

Background

Breast cancer care today involves state-of-the-art biomedical treatment but can fail to address the broader psychosocial and quality-of-life (QoL) issues associated with the transition to breast cancer survivorship. This scoping review examines the evidence on the influence of psychosocial determinants on QoL in breast cancer survivors.

Methods

Scoping review methodology was used to: (1) identify the research question(s); (2) identify relevant studies; (3) undertake study selection; (4) extract data; (5) collate, summarise and report the results.

Results

A total of 33 studies met the inclusion criteria. The majority of studies were conducted in the US (n = 22, 67%) and were mainly cross-sectional (n = 26, 79%). Sixteen psychosocial determinants of QoL were identified. Social support (n = 14, 42%), depression (n = 7, 21%) and future appraisal and perspective (n = 7, 21%) were the most frequently investigated determinants. Twelve different QoL measures were used. A range of different measurement tools were also used per psychosocial determinant (weighted average = 6). The 14 studies that measured the influence of social support on QoL employed 10 different measures of social support and 7 different measures of QoL. In general, across all 33 studies, a higher level of a positive influence and a lower level of a negative influence of a psychosocial determinant was associated with a better QoL e.g. higher social support and lower levels of depression were associated with a higher/better QoL. For some determinants such as spirituality and coping skills the influence on QoL varied, but these determinants were less commonly investigated.

Conclusion

Consensus around measures of QoL and psychological determinants would be valuable and would enable research to determine the influence of psychosocial determinants on QoL adequately. Research in other healthcare settings beyond the US is required, in order to understand the influence of organisation and follow-up clinical and supportive care on psychosocial determinants and QoL and to improve the quality of care in breast cancer survivors.

Depression and health-related quality of life among Cambodian patients with cancer

BACKGROUND

Symptom assessment and quality of life (QoL) are considered two of the most important factors in the overall care of cancer patients. Although cancer is one of the leading causes of death after communicable disease in Cambodia, the QoL of Cambodian cancer patients has not been examined previously. This study aimed to describe the QoL of cancer patients in Cambodia.

METHODS

A cross-sectional study was conducted with cancer patients who visited Khmer-Soviet Friendship Hospital in Phnom Penh. Two hundred patients participated in this study. The inventory comprised two previously validated scales: the Center for Epidemiological Studies Depression Scale-10 (CESD-10) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30. Descriptive analyses, independent samples t-tests, and Pearson's correlation analysis were performed to examine the differences and relationship between study variables.

RESULTS

The mean global health score was 51.62, and 58.5% of the participants had depressive symptom. The global health score was statistically significantly lower in depressive patients. The QoL was negatively correlated with depression, but positively and significant correlated with physical function, role function, emotional function, cognitive function, and social function.

CONCLUSION

This study is the first to describe the QoL of Cambodian cancer patients. Our findings suggest that more attention should be paid to psychological concerns and symptom management in Cambodian cancer patients. Appropriate management could be effective in improving the QoL of cancer patients.

Management of Emotionally Challenging Responses of Hospitalized Patients with Cancer

Cancer is the second leading cause of death in the United States, and the majority of hospital admissions of patients with cancer occur because of uncontrolled, urgent symptoms. In addition to complex physical presentations, these patients often manifest a number of complex emotional and psychological responses resulting in a unique set of healthcare needs and expectations. Inpatient generalists or hospitalists frequently serve as the primary providers of medical care for these patients. Formal training for nononcologists on effective communication strategies in managing patients with cancer in a hospital setting may not fully prepare generalists for challenging patient encounters, however. This review assists generalists in approaching emotionally charged encounters when caring for patients with cancer on the wards. We explore patient factors that negatively affect successful communication, some of which can be addressed through a multidisciplinary approach. In addition, we present a checklist of preventive strategies in addressing emotionally charged patient responses and offer a number of preventive and restorative management approaches for dealing with such encounters. We provide a practical framework for recognition and management of the psychosocial and emotional challenges in the care of hospitalized patients with cancer.
