Adaptation of an Evidence-Based Arthritis Program for Breast Cancer Survivors on Aromatase Inhibitor Therapy Who Experience Joint Pain

Randomized phase II study of a home-based walking intervention for radiation-related fatigue among older patients with breast cancer

BACKGROUND

Fatigue is a common side effect of radiation therapy and can dramatically affect the quality of life in older cancer patients. We compared a home-based graduated walking intervention with a fixed walking recommendation.recommendation to exercise to determine the effects of these interventions during adjuvant radiotherapy (RT) on older women with breast cancer.

METHODS

A randomized phase 2 trial in women ≥65 years, with stage 0-3 breast cancer. Prior to initiating breast RT, women were randomized to a Home-Based Graduated Walking Program (HBGWP) or a fixed walking recommendation. The primary outcome of fatigue was measured by the Total Disruption Index (TDI) of the Fatigue Symptom Inventory (FSI). Secondary outcomes including a short physical performance battery (SPPB) and questionnaires on exercise, physical function, fatigue (PROMIS Fatigue), and fatigue-related symptoms were collected at 3 time points. The primary goal was to compare the change in TDI between arms at the end of RT. Random coefficients models were used to determine the association between arm, fatigue, and exercise over time. Linear regression models were used to describe the change in outcome variables between visits.

RESULTS

Median age of the 54 participants (27 per arm) was 69 years (range 65-84). The baseline characteristics were similar between study arms. The number of minutes walking per week increased in both arms (mean 21 min/wk. baseline to 83 min/wk. end of RT, p < 0.01) and physical function improved over time in both arms (median 10.5 at baseline to 12 at end of RT, p < 0.01).There was no significant difference in change in TDI between arms (2.7 ± 9.9 vs. 1.8 ± 14.0, p = 0.61)between baseline and end of RT. However, in our linear regression model increasing walking over time was associated with statistically significant lower levels of fatigue (-2.44+/- 1.04, p = 0.04), but not in posthoc subgroup analyses.

CONCLUSION

The HBGWP did not decrease fatigue more than the fixed recommendation to exercise. Both the graduated intervention and fixed recommendation lead to increased walking which was associated with lower fatigue in this study of older adult breast cancer patients.

Recent advances in computational tools and resources for the self-management of type 2 diabetes

Background: While healthcare systems are investing resources on type 2 diabetes patients, self-management is becoming the new trend for these patients. Due to the pervasiveness of computing devices, a number of computerized systems are emerging to support the self-management of patients.Objective: The primary objective of this review is to identify and categorize the computational tools that exist for the self-management of type 2 diabetes, and to identify challenges that need to be addressed.Results: The tools have been categorized into web applications, mobile applications, games and ubiquitous diabetes management systems. We provide a detailed description of the salient features of each category along with a comparison of the various tools, listing their challenges and practical implications. A list of platforms that can be used to develop new tools for the self-management of type 2 diabetes, namely mobile applications development, sensor development, cloud computing, social media, and machine learning and predictive analysis platforms, are also provided.Discussions: This paper identifies a number of challenges in the existing categories of computational tools and consequently presents possible avenues for future research. Failure to address these issues will negatively impact on the adoption rate of the self-management tools and applications.

Randomized Controlled Trial of a Home-Based Walking Program to Reduce Moderate to Severe Aromatase Inhibitor-Associated Arthralgia in Breast Cancer Survivors

BACKGROUND

In postmenopausal women diagnosed with breast cancer (BC), most BC tumors are hormone receptor positive and guidelines recommend adjuvant endocrine therapy that includes an aromatase inhibitor (AI). This study investigates the impact of a 6-week, home-based, self-directed walking program on the commonly reported side effect of AI-associated arthralgia (AIAA).

MATERIALS AND METHODS

In this phase II trial, consented BC patients were randomized to walking Intervention (n = 31) or Wait List Control (WLC; n = 31). Eligibility criteria included: stage 0-III BC, on AI for at least 4 weeks, ≥3 on a 5-point scale inquiring about joint symptom intensity "at its worst," and exercising ≤150 minutes per week. Outcomes were self-reported joint symptoms and psychosocial measures. Analyses comparing Intervention and WLC groups were conducted on an intention-to-treat basis to assess intervention impact at 6 weeks (postintervention) and at 6-months follow-up. Adjusted means were calculated to assess differences in two groups.

RESULTS

In our final sample (n = 62), mean age was 64 years, 74% were white, and 63% had a body mass index of 30 or higher. At postintervention, Intervention group participants reported significantly increased walking minutes per week, reduced stiffness, less difficulty with activities of daily living (ADL), and less perceived helplessness in managing joint symptoms. At 6-months follow-up (postwalking period in both Intervention and WLC), walking minutes per week had decreased significantly; however, improvements in stiffness and difficulty with ADLs were maintained.

CONCLUSION

This study adds to the growing evidence base suggesting exercise as a safe alternative or adjunct to medications for the management of AIAA.

IMPLICATIONS FOR PRACTICE

Breast cancer survivors whose adjuvant endocrine treatment includes an aromatase inhibitor (AI) often experience the side effect of AI-associated arthralgia (AIAA). This study investigates the impact of a 6-week, home-based, self-directed walking program in the management of AIAA. Compared with Wait List Control, women in the Intervention group reported significantly increased walking minutes per week, reduced stiffness, less difficulty with activities of daily living, and less perceived helplessness in managing joint symptoms. This study adds to the growing evidence base suggesting exercise as a safe alternative or adjunct to medications for the management of AIAA.

Antihormonal treatment associated musculoskeletal pain in women with breast cancer in the adjuvant setting

PURPOSE

Antihormonal treatment is an effective therapy in the adjuvant setting. However, musculoskeletal pain is a common adverse effect encountered in patients receiving this treatment. We aimed to evaluate the risk factors for the development of antihormonal treatment-associated musculoskeletal pain (AHAMP) and its impact on the health-related quality of life (HRQOL).

PATIENTS AND METHODS

A cross-sectional survey of 78 consecutive breast cancer patients receiving adjuvant antihormonal treatment for early-stage breast cancer in an academic medical oncology clinic was conducted. AHAMP was assessed by Health Assessment Questionnaire (HAQ) and 10 cm visual analog scale (VAS). HRQOL was assessed by self-administered short form 36 and Functional Assessment of Cancer Therapy-Breast subscale surveys.

RESULTS

AHAMP was found to be present in 37 (47.7%) patients. In multivariate regression analysis, having a normal body mass index (<30 kg/m(2)), cigarette smoking, and low serum vitamin D level (20 ng/mL) were found to be independent risk factors. In HRQOL assessment, physical and mental scores were found to be significantly lower in patients with joint arthralgia.

CONCLUSION

AHAMP has an adverse effect on the quality of life of breast cancer patients receiving adjuvant antihormonal treatment, and assessment of predictive factors is important for identification of patient groups at risk of developing this condition.

Treatment with Ruta graveolens 5CH and Rhus toxicodendron 9CH may reduce joint pain and stiffness linked to aromatase inhibitors in women with early breast cancer: results of a pilot observational study

OBJECTIVE

To determine the possible effect of two homeopathic medicines, Ruta graveolens 5CH and Rhus toxicodendron 9CH, in the prevention of aromatase inhibitor (AI) associated joint pain and/or stiffness in women with early, hormone-receptor positive, breast cancer.

METHODS

This prospective, unrandomized observational study was carried out between April and October 2014. Women were recruited in two groups, according to which of the two study centres they attended: one receiving homeopathy in addition to standard treatment (group H) and a control group, receiving standard treatment (group C). All women were treated with an AI. In addition, women in group H also took Ruta graveolens 5CH and Rhus toxicodendron 9CH (5 granules, twice a day) up to 7 days before starting AI treatment. The homeopathic medicines were continued for 3 months. Demographic and clinical data were recorded using a self-assessment questionnaire at inclusion (T0) and 3 months (T3). Primary evaluation criteria were the evolution of scores for joint pain and stiffness, the impact of pain on sleep and analgesic consumption in the two groups after 3 months of treatment.

RESULTS

Forty patients (mean age 64.9±8.1 years) were recruited, 20 in each group. Two-thirds of the patients had joint pain before starting AI treatment. There was a significant difference in the evolution of mean composite pain score between T0 and T3 in the two groups (-1.3 in group H vs. +3.4 in group C; p=0.0001). The individual components of the pain score (frequency, intensity and number of sites of pain) also decreased significantly in group H. Nine patients in group C (45%) vs. 1 (5%) in group H increased their analgesic consumption between T0 and T3 (p=0.0076). After 3 months of treatment, joint pain had a worse impact on sleep in patients in group C (35% vs. 0% of patients; p=0.0083). The differences observed in the evolution of morning and daytime stiffness between the two groups were smaller (p=0.053 and p=0.33, respectively), with the exception of time necessary for the disappearance of morning stiffness which was greater in group C (37.7±23.0 vs. 17.9±20.1 min; p=0.0173).

CONCLUSION

These preliminary results suggest that treatment with Ruta graveolens 5CH and Rhus toxicodendron 9CH may decrease joint pain/stiffness in breast cancer patients treated with AIs. A larger-scale randomized study is required to confirm these results.

Aromatase inhibitor associated arthralgia: the importance of oncology provider-patient communication about side effects and potential management through physical activity

PURPOSE

Breast cancer survivors on aromatase inhibitors (AI) often experience side effects of joint pain, stiffness, or achiness (arthralgia). This study presents findings from a qualitative study of survivors on an AI regarding their knowledge of potential joint pain side effects and how both AI side effects and their management through moderate physical activity could be discussed during routine visits with their oncology provider.

METHODS

Qualitative data from semi-structured interviews were content analyzed for emergent themes. Descriptive statistics summarize sample characteristics.

RESULTS

Our sample included 36 survivors, mean age of 67 (range 46-87); 86 % Caucasian and 70 % had education beyond high school. AI experience are as follows: 64 % anastrozole/Arimidex, 48 % letrozole/Femara, and 31 % exemestane/Aromasin. Participants expressed interest in having more information about potential joint pain side effects when the AI was prescribed so they could understand their joint symptoms when they appeared or intensified. They were relieved to learn that their joint symptoms were not unusual or "in their head." Participants would have been especially motivated to try walking as a way to manage their joint pain if physical activity had been recommended by their oncologist.

CONCLUSIONS

Breast cancer survivors who are prescribed an AI as part of their adjuvant treatment want ongoing communication with their oncology provider about the potential for joint pain side effects and how these symptoms may be managed through regular physical activity. The prescription of an AI presents a "teachable moment" for oncologists to recommend and encourage their patients to engage in regular physical activity.
