Determination of a cut-off COmprehensive Score for financial Toxicity (COST) for identifying cost-related treatment nonadherence and impaired health-related quality of life among Chinese patients with cancer.

PURPOSE: This study aimed to determine a cut-off for the simplified Chinese version of the COmprehensive Score for financial Toxicity (COST) that could identify cost-related treatment nonadherence among Chinese patients with cancer. The study also sought to validate this cut-off score by using it to assess impaired health-related quality of life (HRQoL) in the same population. METHODS: A secondary analysis was conducted using data from a cross-sectional survey of 1208 Chinese patients with cancer who were recruited from 12 hospitals in six cities across three provinces of the Chinese mainland. Sociodemographic information and data on financial toxicity (FT), cost-related treatment nonadherence, and HRQoL were used in the analysis. Receiver operating characteristic (ROC) analysis was used to determine the optimal cut-off for the simplified Chinese version of the COST. RESULTS: The ROC analysis identified a COST cut-off of 18.5 for identifying cost-related treatment nonadherence, yielding a sensitivity of 76.5% and specificity of 71.4%. In the validation study, this cut-off score yielded a sensitivity of 64.2% and a specificity of 67.1% for identifying impaired HRQoL. CONCLUSION: Early and dynamic assessment of cancer-related FT in routine clinical practice may play a crucial role in the early identification and management of FT. Accordingly, a COST cut-off of 18.5 was identified to indicate cost-related treatment nonadherence and impaired HRQoL in a population of patients with cancer from the Chinese mainland. This finding may facilitate the implementation of universal FT screening among patients with cancer in specific settings such as the Chinese mainland.

Communication of costs and financial burdens between cancer patients and healthcare providers: a qualitative systematic review and meta-synthesis.

OBJECTIVES: The aim of this study was to synthesize qualitative research regarding communication of costs and financial burdens between patients and healthcare providers to provide evidence for the subsequent development of intervention programs. METHODS: Studies published prior to 11 February 2023 were collected from electronic databases, including PubMed/MEDLINE, MEDLINE (Ovid), Web of Science, EMBASE (Ovid), CINAHL (EBSCO), and ProQuest. A checklist for qualitative research drawn from the Joanna Briggs Institute Reviewer's Manual was applied to assess the quality of the included studies. Meta-aggregation was performed to synthesize the findings of the included studies. RESULTS: Four synthesized findings were derived from 15 studies: cost communication offered more benefits than drawbacks, and most patients were willing to engage in cost communication; cost communication has been implemented in clinical practice but continued to face shortcomings and barriers; an expected cost communication should take into account timing, location, personnel, personality, and content; healthcare providers required education, information, tools, standardized processes, and policy and organizational support to increase their ability to deliver cost communication. CONCLUSIONS: Cost communication can help optimize decision-making and reduce the risk of financial difficulties, as has been widely recognized by patients and healthcare providers. However, a complete clinical practice plan to facilitate cost communication has not yet been created.

Use of a Linguistically Appropriate Decision Aid for Cervical Cancer Screening of South Asian Ethnic Minority Women in Hong Kong: A Pilot Randomised Controlled Trial.

BACKGROUND: Decision aids have been shown to be effective in assisting the decision-making process in healthcare settings. This study aimed to examine the feasibility and acceptability of a linguistically appropriate printed decision aid for cervical cancer screening in South Asian women and to preliminarily estimate its effects on decisional conflicts, clarity of values, risk perception, the screening decision and screening uptake. METHODS: This was a pilot randomised controlled trial. Forty-eight South Asian women aged 25 to 64 years were recruited and allocated to either the intervention group or control group. The participants in the intervention group read a linguistically appropriate printed decision aid. RESULTS: All of the participants in the intervention group agreed that the decision aid was useful in aiding their decision-making. These participants showed significantly greater improvement in decisional conflicts, clarity of values and risk perceptions than those in the control group (all p < 0.05). The screening uptake rate was significantly higher in the intervention group than in the control group (p < 0.001). CONCLUSIONS: The decision aid was feasible and acceptable among South Asian women, and it resulted in reduced decisional conflict and increased screening uptake compared with usual care. To improve the convenience of using decision aids, they could be developed in various forms, such as printed and mobile application forms, to meet individual requirements. TRIAL REGISTRATION: The trial was registered at the Chinese Clinical Trial Registry on 23 October 2021 (ChiCTR2100052225).

Needs assessment instruments for family caregivers of cancer patients receiving palliative care: a systematic review.

PURPOSE: Family caregivers of palliative cancer patients experience various supportive care needs. Appropriate self-reported instruments with robust psychological properties are required to identify these needs of family caregivers. Therefore, we conducted a systematic review to identify self-reported supportive care needs assessment instruments for family caregivers of palliative cancer patients and assess their contents, psychometric properties, and applicability. METHODS: Systematic searches were conducted in six English databases and four Chinese databases from inception to October 2020 and updated in June 2021. The instruments identified were evaluated using an 18-item checklist consisting of six domains: conceptual model, content validity, reliability, construct validity, scoring and interpretation, and respondent burden and presentation. RESULTS: Six articles, describing four self-reported needs assessment instruments, were included in the review. These instruments varied significantly in terms of contents, constructs, scoring methods, and applicability. Three of these instruments were developed to assess the comprehensive supportive care needs of family caregivers, while one was specifically developed to assess the spiritual needs of family caregivers. With respect to psychometric properties, none of the instruments identified met all the criteria. Three major shortcomings were identified, namely, lack of longitudinal validity, lack of a strategy for interpreting missing data, and lack of a description of the literacy level required to understand the questions. Additionally, the instrument development processes assessed in this study lacked qualitative elements. CONCLUSIONS: End-users need to consider contents, psychometric properties, and applicability when choosing an appropriate needs assessment instrument according to individual purpose and context. Further evaluation or development of needs assessment for the family caregivers of palliative cancer patients is needed, with a particular emphasis on caregivers' perspectives.

Influential barriers perceived by South Asians in Hong Kong to undergoing cervical cancer screening.

OBJECTIVE: To report the uptake rate of cervical cancer screening (the Papanicolaou [Pap] test) and identify the perceived barriers associated with screening uptake among South Asian women in Hong Kong. METHODS: This cross-sectional study involved a structured survey of 776 South Asian women aged 21 and above, recruited from the community. The participants' demographic characteristics, Pap test uptake and responses to a validated 14-item scale of perceived barriers to screening was collected. The data were analysed using descriptive statistics and logistic regression. RESULTS: The Pap test uptake rate was 40.3%. Multivariate analysis identified two perceived barriers significantly associated with the participants' Pap test uptake: (1) not knowing where to have the test and (2) the belief that they did not need a test if they felt well. CONCLUSION: Although language problems and embarrassment are commonly reported barriers to screening by South Asians, the participants were more concerned about where to have the test and whether they needed it. Future interventions should thus focus on enhancing their access to the service and clarifying their understanding of the need.

Identifying the factors promoting colorectal cancer screening uptake in Hong Kong using Andersen's behavioural model of health services use.

BACKGROUND: Colorectal cancer (CRC) screening is an effective strategy to aid early cancer detection. However, the decision to undergo screening can be affected by a variety of factors. The aims of this study were to examine current CRC screening uptake in Hong Kong and identify the factors associated with it using Andersen's Behavioural Model as a guiding framework. METHODS: This cross-sectional study was conducted in Hong Kong from August 2019 to December 2020. A sample of 1317 Chinese individuals aged 50 to 75 years were recruited and completed a survey to identify predisposing, enabling, and need-for-care factors, and the colorectal cancer screening uptake rate (faecal occult blood test [FOBT] or faecal immunochemical test [FIT] and colonoscopy) was determined. RESULTS: The FOBT/FIT uptake rate was 43.9%, while that of the colonoscopy was 26.0%. The provision of a government subsidy for screening and the provision of information booklets were the most significant and second most significant enabling factors for FOBT/FIT uptake, respectively. Visiting a doctor five times or more in the previous year and being recommended to undergo a CRC screening by a doctor, were the most significant enabling factors for colonoscopy uptake. Age, the perceived benefit of and barriers to screening were important predisposing factors for FOBT/FIT and colonoscopy uptake. CONCLUSIONS: Screening uptake rates in Hong Kong have significantly increased over the last decade, although they remain lower than those in other countries. Continual efforts are warranted to promote government-subsidised screening. Relevant educational materials that address the barriers identified in this study should be developed and disseminated to the public.

Development and evaluation of a multimedia intervention to promote cervical cancer prevention among South Asian women in Hong Kong.

Objective: The uptake of cervical cancer screening among South Asian ethnic minorities is low, rendering them at higher risk of developing cervical cancer. Interventions should, therefore, be developed to enhance their knowledge of this disease and its prevention. We developed and implemented a Health-Belief-Model-based and culturally sensitive multimedia intervention for South Asian women in Hong Kong, and evaluated its feasibility, acceptability and effectiveness using the Reach-Effectiveness-Adoption-Implementation-Maintenance framework.Design: At post-intervention, a short survey was conducted to assess the participants' perceptions of the acceptability and effectiveness of the intervention. Focus group and/or telephone interviews with persons-in-charge of community organizations were conducted to collect feedback on the intervention's effectiveness and long-term sustainability.Results: The intervention was implemented successfully in partnership with 54 community organizations, of which 51 expressed a willingness to continue doing so at their centers. 1061 South Asian women received the intervention through attendance at the 51 health talks held. Over 90% of them agreed that the intervention was acceptable and effective.Conclusions: The intervention appeared to be feasible, and is potentially effective in enhancing participants' knowledge of cervical cancer and self-efficacy in undergoing screening.

Translation and validation of the Traditional Chinese version of the COmprehensive Score for financial Toxicity-Functional Assessment of Chronic Illness Therapy (Version 2).

BACKGROUND: Cancer patients often experience severe financial distress due to the high cost of their treatment, and strategies are needed to objectively measure this financial distress. The COmprehensive Score for financial Toxicity-Functional Assessment of Chronic Illness Therapy (COST-FACIT) is one instrument used to measure such financial distress. This study aimed to translate the COST-FACIT (Version 2) [COST-FACIT-v2] instrument into traditional Chinese (COST-FACIT-v2 [TC]) and evaluate its psychometric properties. METHODS: The Functional Assessment of Chronic Illness Therapy (FACIT) translation method was adopted. The translated version was reviewed by an expert panel and by 20 cancer patients for content validity and face validity, respectively, and 640 cancer patients, recruited from three oncology departments, completed the translated scale. Its reliability was evaluated in terms of internal consistency and test-retest reliability. Confirmatory factor analysis has been used to evaluate the one- and two-factor structures of the instrument reported in the literature. The convergent validity was examined by the correlation with health-related quality of life (HRQoL) and psychological distress. Known-group validity was examined by the difference in the COST-FACIT-v2 (TC) total mean score between groups with different income levels and frequency of health care service use. RESULTS: The COST-FACIT-v2 (TC) showed good content and face validity and demonstrated high internal consistency (Cronbach's alpha, 0.86) and acceptable test-retest reliability (intraclass correlation coefficient, 0.71). Confirmatory factor analysis showed that the one- and two-factor structures of the instrument that have been reported in the literature could not be satisfactorily fitted to the data. Psychological distress correlated significantly with the COST-FACIT-v2 (TC) score (r = 0.47; p < 0.001). HRQOL showed a weak to moderate negative correlation with the COST-FACIT-v2 (TC) score (r = - 0.23 to - 0.46; p < 0.001). Significant differences were seen among the COST-FACIT-v2 (TC) scores obtained in groups of different income level and frequency of health care service use. CONCLUSIONS: The COST-FACIT-v2 (TC) showed some desirable psychometric properties to support its validity and reliability for assessing cancer patients' level of financial toxicity.

Actigraphy-measured rest-activity circadian rhythm disruption in patients with advanced cancer: a scoping review.

PURPOSE: Patients with later-stage cancer have been reported to demonstrate more disrupted rest-activity circadian rhythms (RACR) than those with earlier-stage cancer, but consolidated evidence of this is lacking. The aim of this review was to examine and map the existing evidence on actigraphy-measured RACR in terms of their (1) pattern, (2) prevalence, (3) related factors, and (4) outcomes in advanced cancer patients. METHODS: A comprehensive scoping review was conducted using Arksey and O'Malley's framework. A literature search was performed using nine databases: MEDLINE, Embase, PsycINFO, CINAHL, British Nursing Index, Cochrane Library, Scopus, Web of Science, and SINTA. RESULTS: Twenty-one studies were included in the review. Compared with the healthy population, advanced cancer patients were more likely to display weaker RACR, manifesting as lower activity levels during the day, more frequent and longer daytime naps, and fragmented nighttime sleep. The prevalence of RACR disruption among advanced cancer patients ranged from 31.3 to 54.9%. It was found to be linked to the presence of physical and psychological symptoms (fatigue, appetite loss, pain, dyspnoea, sleep disturbance, depression, and anxiety), chemotherapy, male sex, and also predict the lower quality of life and survival. CONCLUSION: Disruption of the RACR is prevalent in advanced cancer patients and is associated with a set of physical and psychological symptoms. It was also found to be a predictor of the quality of life and survival among these patients. These results indicate the importance of interventions to restabilise the disrupted RACR among advance cancer patients to improve their health outcomes.

Identifying a cut-off score for the COST measure to indicate high financial toxicity and low quality of life among cancer patients.

PURPOSE: To identify a cut-off score for the COmprehensive Score for financial Toxicity (COST) to predict a clinical implication of a high level of financial toxicity (FT). METHODS: A total of 640 cancer patients were recruited from three regional hospitals in Hong Kong. They completed a questionnaire comprising the COST measure and the Functional Assessment of Cancer Therapy - General (FACT-G) instrument. The cut-off score for the COST that predicts the lowest quartile of the FACT-G total score was identified by receiver operating characteristic (ROC) analysis. The sample was then stratified by this cut-off score, and characteristics were compared using Fisher's exact, chi-squared or independent sample t-test. RESULTS: The mean scores were 20.1 ± 8.8 for the COST and 71.6 ± 15.5 for the FACT-G. The ROC analysis suggested that the cut-off of 17.5 yielded an acceptable sensitivity and specificity. Characteristics of patients with a higher level of FT included being younger, having a monthly household income of < 10,000 HKD (approximately 1290 USD), being more likely not employed, having stage IV cancer and receiving targeted and/or immunotherapy. In terms of financial support, a higher proportion of these patients had discussed financial issues with health care professionals and had received financial assistance. In addition, fewer of them were covered by private health insurance. CONCLUSION: Our findings suggest a cut-off for the COST that can be used to screen for FT in clinical settings. In addition, while a considerable proportion of high-FT patients received targeted therapy, they often received financial assistance. There is a gap between financial hardship and assistance that warrants attention.

Essential oncology nursing care along the cancer continuum.

Oncology nurses are at the heart of tackling the increasing global burden of cancer. Their contribution is unique because of the scale and the diversity of care roles and responsibilities in cancer care. In this Series paper, to celebrate the International Year of the Nurse and Midwife, we highlight the contribution and impact of oncology nurses along the cancer care continuum. Delivering people-centred integrated care and optimal communication are essential components of oncology nursing care, which are often played down. More oncology nurses using, doing, and leading research will further show the key nursing impact on care as part of a team. The oncology nurse influence in saving lives through prevention and early detection of cancer is noteworthy. Supportive care, the central pillar of oncology nursing, enables and empowers people to self-manage where possible. Globally, oncology nurses make a great positive difference to cancer care worldwide; their crucial contribution throughout the continuum of care warrants the inclusion and promotion of nursing in every country's cancer strategy. 2020 is the year of the nurse: let us take this learning to the future.

Electroacupuncture trigeminal nerve stimulation plus body acupuncture for chemotherapy-induced cognitive impairment in breast cancer patients: An assessor-participant blinded, randomized controlled trial.

Chemotherapy causes various side effects, including cognitive impairment, known as 'chemobrain'. In this study, we determined whether a novel acupuncture mode called electroacupuncture trigeminal nerve stimulation plus body acupuncture (EA/TNS + BA) could produce better outcomes than minimum acupuncture stimulation (MAS) as controls in treating chemobrain and other symptoms in breast cancer patients. In this assessor- and participant-blinded, randomized controlled trial, 93 breast cancer patients under or post chemotherapy were randomly assigned to EA/TNS + BA (n = 46) and MAS (n = 47) for 2 sessions per week over 8 weeks. The Montreal Cognitive Assessment (MoCA) served as the primary outcome. Digit span test was the secondary outcomes for attentional function and working memory. The quality of life and multiple functional assessments were also evaluated. EA/TNS + BA treated group had much better performance than MAS-treated group on reverse digit span test at Week 2 and Week 8, with medium effect sizes of 0.53 and 0.48, respectively, although no significant differences were observed in MoCA score and prevalence of chemobrain between the two groups. EA/TNS + BA also markedly reduced incidences of diarrhoea, poor appetite, headache, anxiety, and irritation, and improved social/family and emotional wellbeing compared to MAS. These results suggest that EA/TNS + BA may have particular benefits in reducing chemotherapy-induced working memory impairment and the incidence of certain digestive, neurological, and distress-related symptoms. It could serve as an effective intervention for breast cancer patients under and post chemotherapy (trial registration: https://www.clinicaltrials.gov: NCT02457039).

Cancer survivors' experiences with financial toxicity: A systematic review and meta-synthesis of qualitative studies.

OBJECTIVE: The aim of this study was to synthesize qualitative research evidence on cancer survivors' experiences with financial toxicity (FT). METHODS: We carried out a systematic review of qualitative studies using a meta-aggregation approach. Papers published prior to 31 August 2019, were collected from electronic databases, including PubMed/MEDLINE, MEDLINE (Ovid), EMBASE (Ovid), CINAHL (EBSCO), Web of Science, ProQuest Dissertations and Theses, and Cochrane Library (Wiley). RESULTS: Six synthesized findings were derived from 14 studies covering cancer patients' awareness of FT, cancer-related expenditures, and the risk factors, impacts, coping strategies, and unmet needs related to FT. CONCLUSIONS: Cancer survivors incur FT; however, their awareness of FT is limited. Cancer-related FT has multiple impacts on survivors' lives. Although cancer survivors try to cope with FT through adjustments, they still have unmet needs for the management of FT. Nurses and social workers can play a critical role in helping survivors manage FT by increasing pre-awareness of FT, strengthening emotional empowerment, and providing personalized informative support.

Malnutrition risks and their associated factors among home-living older Chinese adults in Hong Kong: hidden problems in an affluent Chinese community.

BACKGROUND: Although China is undergoing rapid economic development, it is facing an ageing population. No data exists on malnutrition risks of older adults in an affluent Chinese society. The aim of this study is to examine these risks and identify their associated factors among home-living older Chinese adults in Hong Kong. METHODS: This is a cross-sectional study, to which home-living subjects aged 60 or above were recruited, between May and September 2017, from a non-governmental community organisation located in three different districts of Hong Kong. Nutritional status was assessed by the Mini Nutritional Assessment (MNA), and its associated factors examined included socio-demographic characteristics, lifestyle, health status and diet. Multivariable logistic regression analysis was performed to identify factors associated with malnutrition risks (MNA < 24). RESULTS: Six hundred thirteen subjects (mean age: 78.5 ± 7.4; 54.0% females) completed the survey. Nearly 30% (n = 179) were at risk of malnutrition. By multivariable logistic regression, subjects (1) whose vision was only fair or unclear, (2) with poor usual appetite and (3) with main meal skipping behaviour had significantly higher malnutrition risk (all p < 0.05). CONCLUSIONS: In this affluent Chinese society, the malnutrition risk in older adults is close to the global average, which is a matter for much concern. Interventions are therefore warranted that target vulnerable groups with poor vision, appetite, and meal skipping behaviour. TRIAL REGISTRATION: Not applicable.

A family-based multimedia intervention to enhance the uptake of colorectal cancer screening among older South Asian adults in Hong Kong: a study protocol for a cluster randomized controlled trial.

BACKGROUND: Colorectal cancer (CRC) screening, such as fecal occult blood test (FOBT), is an effective way to prevent CRC, one of the most common cancers worldwide. However, studies found that South Asian ethnic minorities tend not to utilize CRC screening, whose importance on CRC prevention shall be educated among those from ethnic minorities, especially older adults. The purpose of this study is to develop and implement a family-based, multimedia intervention to augment the knowledge of CRC prevention among older South Asian adults in Hong Kong and enhance their motivation for undergoing FOBT. The acceptability and effectiveness of the intervention will be assessed using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework. METHODS: A cluster randomized controlled trial will be carried out. Three hundred and twenty South Asian dyads, comprising an older adult aged between 50 and 75 and a younger family member aged between 18 and 49, will be recruited in ten districts in Hong Kong through community organizations that provide support services for South Asians in local communities. Dyads will be randomly allocated to either the intervention or wait-list control group. Intervention dyads will receive intervention, whose contents are based on the health belief model, via multiple forms of media including PowerPoint presentation, video clip and health information booklet. Control dyads will receive intervention after post-intervention data are collected. For dyads in both groups, an appointment with a family doctor will be arranged for those willing to undergo FOBT. Outcomes will be assessed at baseline and post-intervention. Data will be analysed using the Generalised Linear Models Procedure in an intention-to-treat manner. DISCUSSION: Findings of this study will provide evidence of the benefits of utilizing multimedia and family-based approaches in intervention development to enhance the effectiveness of health promotion interventions for ethnic minorities. Further, the findings would provide reference to the potential incorporation of the intervention in the existing support services for South Asian ethnic minorities in local communities. TRIAL REGISTRATION: This trial is registered at the ISRCTN Registry ( ISRCTN72829325 ) on 19th July 2018.

A feasibility study on using tablet personal computers for self-reported symptom assessment in newly diagnosed lung cancer patients.

AIM: The study aimed to assess the feasibility and acceptability of an innovative tablet-assisted self-reported symptom assessment among newly diagnosed lung cancer patients. BACKGROUND: Routine symptom assessment for lung cancer patients in a fast-paced clinical environment is demanding. Mobile health technology offers a potential platform for symptom assessment and paves the way for tailored self-care intervention. DESIGN: A feasibility study using a mixed method design. METHOD: A convenience sample of 10 newly diagnosed lung cancer patients used tablet personal computers to self-report common symptoms: dyspnoea, fatigue, pain, and anxiety. A nurse reviewed the assessment results and provided tailored educational interventions. Acceptability was evaluated by the Electronic Self-Report Assessment-Cancer. Semi-structured interviews were conducted to explore the patients' perceptions of this symptom assessment method. Data were collected from January to March 2016. RESULTS: An Electronic Self-Report Assessment-Cancer mean score of 23.5 (SD 2.7) showed moderate acceptance of the assessment method. Participants found this approach user-friendly and helpful in identifying their symptoms and they gained awareness and better understanding of them. CONCLUSION: Tablet-assisted symptom assessment is a feasible method that can be further tested in busy clinical settings to assess symptom burden and identify individual needs for tailoring symptom management plans.

Profiling of the silica-induced molecular events in lung epithelial cells using the RNA-Seq approach.

Silicosis is a prolonged, irreversible and incurable occupational disease, and there is a significant number of newly diagnosed cases every year in Hong Kong. Due to the long latency of the disease, the diagnosis can be missed until detailed clinical examination at a later stage. For a better control of this deadly disease, detailing the pro-inflammatory and fibrotic events in the macrophage would be instrumental in understanding the pathogenesis of the disease and essential for the significant biomarkers discovery. In this in vitro study, human cell line model A549 lung epithelial cells were used. The immediate molecular events underneath the activation of quartz silica polymorphs were followed in a time course of 0, 0.5, 2, 8, 16 and 24 h. The transcriptome library was prepared and subjected to RNA-Seq analysis. Data analysis was performed by pathway analysis tools and verified by real-time PCR. The results showed that triggered genes were mainly found in the immune response and inflammatory pathways. An interesting finding was the association of the DNA-binding protein inhibitor (ID) family in the silica exposure to lung cells. The linkage of ID1, ID2 and ID3 to cancer may rationalize themselves to be the markers indicating an early response of silicosis. However, further studies are required to consolidate the roles of these genes in silicosis. Copyright © 2017 John Wiley & Sons, Ltd.

Hypotheses on the Potential of Rice Bran Intake to Prevent Gastrointestinal Cancer through the Modulation of Oxidative Stress.

Previous studies have suggested the potential involvement of oxidative stress in gastrointestinal cancers. In light of this, research efforts have been focused on the potential of dietary antioxidant intake to prevent gastrointestinal cancer through the modulation of oxidative stress. Rice bran, a by-product of rice milling, has been shown to contain an abundance of phytochemicals, which are dietary antioxidants. To date, a number of studies have shown the antioxidative effect of rice bran intake, and some demonstrated that such an effect may contribute to gastrointestinal cancer prevention, largely through the antioxidative properties of rice bran phytochemicals. In addition, these phytochemicals were shown to provide protection against cancer through mechanisms linked to oxidative stress, including ß-catenin-mediated cell proliferation and inflammation. The present article provides an overview of current evidence for the antioxidative properties of rice bran and its phytochemicals, and for the potential of such properties in cancer prevention through the oxidative-stress-linked mechanisms mentioned above. The article also highlights the need for an evaluation of the effectiveness of rice bran dietary interventions among cancer survivors in ameliorating oxidative stress and reducing the level of gastrointestinal cancer biomarkers, thereby establishing the potential of such interventions among these individuals in the prevention of cancer recurrence.

Novel Strategies on Personalized Medicine for Breast Cancer Treatment: An Update.

Breast cancer is the most common cancer type among women worldwide. With breast cancer patients and survivors being reported to experience a repertoire of symptoms that are detrimental to their quality of life, the development of breast cancer treatment strategies that are effective with minimal side effects is therefore required. Personalized medicine, the treatment process that is tailored to the individual needs of each patient, is recently gaining increasing attention for its prospect in the development of effective cancer treatment regimens. Indeed, recent studies have identified a number of genes and molecules that may be used as biomarkers for predicting drug response and severity of common cancer-associated symptoms. These would provide useful clues not only for the determination of the optimal drug choice/dosage to be used in personalized treatment, but also for the identification of gene or molecular targets for the development of novel symptom management strategies, which ultimately would lead to the development of more personalized therapies for effective cancer treatment. In this article, recent studies that would provide potential new options for personalized therapies for breast cancer patients and survivors are reviewed. We suggest novel strategies, including the optimization of drug choice/dosage and the identification of genetic changes that are associated with cancer symptom occurrence and severity, which may help in enhancing the effectiveness and acceptability of the currently available cancer therapies.
