Exercises for women receiving adjuvant therapy for breast cancer

A review of FDA approved drugs and their formulations for the treatment of breast cancer

Breast cancer is one of the most diagnosed solid cancers globally. Extensive research has been going on for decades to meet the challenges of treating solid tumors with selective compounds. This article aims to summarize the therapeutic agents which are either being used or are currently under approval for use in the treatment or mitigation of breast cancer by the US FDA, to date. A structured search of bibliographic databases for previously published peer-reviewed research papers on registered molecules was explored and data was sorted in terms of various categories of drugs used in first line/adjuvant therapy for different stages of breast cancer. We included more than 300 peer-reviewed papers, including both research and reviews articles, in order to provide readers an useful comprehensive information. A list of 39 drugs are discussed along with their current status, dose protocols, mechanism of action, pharmacokinetics, possible side effects, and marketed formulations. Another interesting aspect of the article included focusing on novel formulations of these drugs which are currently in clinical trials or in the process of approval. This exhaustive review thus shall be a one-stop solution for researchers who are working in the areas of formulation development for these drugs.

The Practice of Physical Activity After Breast Cancer Treatments: A Qualitative Study Among Portuguese Women

Background

Women survivors of breast cancer treatments face significant challenges around initiation or maintenance of physical activity (PA) as they transit to recovery. Embracing their needs and preferences is important to increase adherence. This study aimed to explore the perspectives of Portuguese women survivors of breast cancer regarding regular performance of PA and individual choices and strategies that should be considered in designing effective interventions.

Methods

The individual semi-structured interviews (N = 20) were analyzed through thematic analysis, following an inductive process, seeking to identify the barriers, facilitators, and particular influencing circumstances associated with regular PA.

Results

Four themes and several contextual, emotional, physical, and social factors were identified as determinants of regular PA. Guilt, women’s duties, and altruism to help close relatives were identified as emotional and cultural factors that are less-found in the existing literature. PA showed influence both from health professionals’ counseling and from knowledge and beliefs held by these women.

Conclusion

While confirming the already-known impact of breast cancer diagnosis and treatments on PA, which redefine participants’ availability to be active, the findings highlight beliefs and specific emotional factors that should be considered when planning culturally sensitive interventions.

Prevalence of unmet needs and correlated factors in advanced-stage cancer patients receiving rehabilitation

PURPOSE

Although rehabilitation for patients with cancer is currently being provided throughout all phases of the disease, including the advanced stage, much remains unknown about the needs of such patients. The aims of this study were to identify the supportive care and unmet needs of cancer patients receiving rehabilitation interventions and to investigate the factors associated with those unmet needs.

METHODS

A total of 45 patients with cancer receiving rehabilitation interventions participated in this study between June 2013 and December 2015. Measures included the Japanese version of the Short-Form Supportive Care Needs Survey Questionnaire (SCNS-SF34), the Functional Independence Measure (FIM), the Hospital Anxiety and Depression Scale (HADS), and various other medico-social factors.

RESULTS

The mean age of the cancer patients was 66.6 years, the mean (±standard deviation) FIM score was 111.8 (±16.1), and the mean HADS score was 13.9 (±8.2). The patients had a mean of 17.4 (±10.3) unmet needs. The top ten unmet needs related to rehabilitation intervention included seven psychological needs, two health system and information needs, and one physical and daily living need. Multiple regression analysis revealed that psychological distress (HADS ≥11), marital status, and sex were significantly associated with physical and daily living needs.

CONCLUSIONS

These results suggest that psychosocial factors are important in understanding the supportive care and unmet needs of cancer patients receiving rehabilitation interventions.

Multidimensional rehabilitation programmes for adult cancer survivors

BACKGROUND

Multidimensional rehabilitation programmes (MDRPs) have developed in response to the growing number of people living with and surviving cancer. MDRPs comprise a physical component and a psychosocial component. Studies of the effectiveness of these programmes have not been reviewed and synthesised.

OBJECTIVES

To conduct a systematic review of studies examining the effectiveness of MDRPs in terms of maintaining or improving the physical and psychosocial well-being of adult cancer survivors.

SEARCH METHODS

We conducted electronic searches in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsychINFO up to February 2012.

SELECTION CRITERIA

Selection criteria focused on randomised controlled trials (RCTs) of multidimensional interventions for adult cancer survivors. Interventions had to include a physical component and a psychosocial component and to have been carried out on two or more occasions following completion of primary cancer treatment. Outcomes had to be assessed using validated measures of physical health and psychosocial well-being. Non-English language papers were included.

DATA COLLECTION AND ANALYSIS

Pairs of review authors independently selected trials, rated their methodological quality and extracted relevant data. Although meta-analyses of primary and secondary endpoints were planned there was a high level of study heterogeneity and only one common outcome measure (SF-36) could be statistically synthesised. In addition, we conducted a narrative analysis of interventions, particularly in terms of inspecting and identifying intervention components, grouping or categorising interventions and examining potential common links and outcomes.

MAIN RESULTS

Twelve RCTs (comprising 1669 participants) met the eligibility criteria. We judged five studies to have a moderate risk of bias and assessed the remaining seven as having a high risk of bias. It was possible to include SF-36 physical health component scores from five studies in a meta-analysis. Participating in a MDRP was associated with an increase in SF-36 physical health component scores (mean difference (MD) 2.22, 95% confidence interval (CI) 0.12 to 4.31, P = 0.04). The findings from the narrative analysis suggested that MDRPs with a single domain or outcome focus appeared to be more successful than programmes with multiple aims. In addition, programmes that comprised participants with different types of cancer compared to cancer site-specific programmes were more likely to show positive improvements in physical outcomes. The most effective mode of service delivery appeared to be face-to-face contact supplemented with at least one follow-up telephone call. There was no evidence to indicate that MDRPs which lasted longer than six months improved outcomes beyond the level attained at six months. In addition, there was no evidence to suggest that services were more effective if they were delivered by a particular type of health professional.

AUTHORS' CONCLUSIONS

There is some evidence to support the effectiveness of brief, focused MDRPs for cancer survivors. Rigorous and methodologically sound clinical trials that include an economic analysis are required.

Multidisciplinary rehabilitation for follow-up of women treated for breast cancer

BACKGROUND

Breast cancer is the most common malignancy in women worldwide. Multidisciplinary rehabilitation aims to improve outcomes for women but the evidence base for its effectiveness is yet to be established.

OBJECTIVES

To assess the effects of organised multidisciplinary rehabilitation during follow-up in women treated for breast cancer.

SEARCH METHODS

We searched the Cochrane Breast Cancer Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, CINAHL, AMED, PEDro and LILACS in December 2011.

SELECTION CRITERIA

Randomised and controlled clinical trials (RCTs, CCTs, respectively) that compared multidisciplinary rehabilitation with some form of control intervention (such as a lower level or different type of intervention, minimal intervention, waiting list controls or no treatment, interventions given in different settings).

DATA COLLECTION AND ANALYSIS

The type of data retrieved did not allow for quantitative synthesis and therefore a narrative synthesis was provided. The methodological quality of the included studies was evaluated by three authors using the risk of bias tool.

MAIN RESULTS

Two RCTs, including 262 participants, met the inclusion criteria. Both trials scored poorly for methodological quality. There was 'low level' evidence that multidisciplinary rehabilitation produced short-term gains at the levels of impairment (that is range of shoulder movement), psychosocial adjustment and quality of life after breast cancer treatment (up to 12 months). No evidence was available for the longer-term functional outcomes for caregivers or the cost effectiveness of these programmes. It was not possible to suggest the most appropriate frequency and duration of therapy or choice of one type of intervention over another.

AUTHORS' CONCLUSIONS

There was 'low level' evidence that multidisciplinary rehabilitation can improve the outcomes of people with breast cancer in terms of functional ability, psychosocial adjustment and participation in social activities. There was no evidence available on functional gain at the level of activity. This review highlights the limitations of RCTs in rehabilitation settings and the need for high-quality trial-based research in this area. Regular evaluation and assessment of breast cancer survivors for rehabilitation is recommended.
