Effects of chronic widespread pain on the health status and quality of life of women after breast cancer surgery

Health-related quality of life in breast cancer patients: a bibliographic review of the literature from 1974 to 2007

Background

Quality of life in patients with breast cancer is an important outcome. This paper presents an extensive overview on the topic ranging from descriptive findings to clinical trials.

Methods

This was a bibliographic review of the literature covering all full publications that appeared in English language biomedical journals between 1974 and 2007. The search strategy included a combination of key words 'quality of life' and 'breast cancer' or 'breast carcinoma' in titles. A total of 971 citations were identified and after exclusion of duplicates, the abstracts of 606 citations were reviewed. Of these, meetings abstracts, editorials, brief commentaries, letters, errata and dissertation abstracts and papers that appeared online and were indexed ahead of publication were also excluded. The remaining 477 papers were examined. The major findings are summarized and presented under several headings: instruments used, validation studies, measurement issues, surgical treatment, systemic therapies, quality of life as predictor of survival, psychological distress, supportive care, symptoms and sexual functioning.

Results

Instruments-Several valid instruments were used to measure quality of life in breast cancer patients. The European Organization for Research and Treatment of Cancer Core Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its breast cancer specific complementary measure (EORTC QLQ-BR23) and the Functional Assessment Chronic Illness Therapy General questionnaire (FACIT-G) and its breast cancer module (FACIT-B) were found to be the most common and well developed instruments to measure quality of life in breast cancer patients. Surgery-different surgical procedures led to relatively similar results in terms of quality of life assessments, although mastectomy patients compared to conserving surgery patients usually reported a lower body image and sexual functioning. Systemic therapies-almost all studies indicated that breast cancer patients receiving chemotherapy might experience several side-effects and symptoms that negatively affect their quality of life. Adjuvant hormonal therapies also were found to have similar negative impact on quality of life, although in general they were associated with improved survival. Quality of life as predictor of survival-similar to known medical factors, quality of life data in metastatic breast cancer patients was found to be prognostic and predictive of survival time. Psychological distress-anxiety and depression were found to be common among breast cancer patients even years after the disease diagnosis and treatment. Psychological factors also were found to predict subsequent quality of life or even overall survival in breast cancer patients. Supportive care-clinical treatments to control emesis, or interventions such as counseling, providing social support and exercise could improve quality of life. Symptoms-Pain, fatigue, arm morbidity and postmenopausal symptoms were among the most common symptoms reported by breast cancer patients. As recommended, recognition and management of these symptoms is an important issue since such symptoms impair health-related quality of life. Sexual functioning-breast cancer patients especially younger patients suffer from poor sexual functioning that negatively affect quality of life.

Conclusion

There was quite an extensive body of the literature on quality of life in breast cancer patients. These papers have made a considerable contribution to improving breast cancer care, although their exact benefit was hard to define. However, quality of life data provided scientific evidence for clinical decision-making and conveyed helpful information concerning breast cancer patients' experiences during the course of the disease diagnosis, treatment, disease-free survival time, and recurrences; otherwise finding patient-centered solutions for evidence-based selection of optimal treatments, psychosocial interventions, patient-physician communications, allocation of resources, and indicating research priorities were impossible. It seems that more qualitative research is needed for a better understanding of the topic. In addition, issues related to the disease, its treatment side effects and symptoms, and sexual functioning should receive more attention when studying quality of life in breast cancer patients.

Postmastectomy neuropathic pain: results of microsurgical lymph nodes transplantation

Postmastectomy chronic pain may be divided into widespread and regional pain. Almost half patients with regional pain, which is more likely related to neuropathic phenomena, do not benefit any pain relief from medication. Our purpose was to report results on pain relief obtained by axillary lymph nodes autotransplantation.

METHODS

Six patients presented with chronic regional neuropathic pains and upper limb lymphedema after breast cancer surgery and radiation therapy. Despite medication, pain was intolerable and daily activity dramatically reduced. Lymph nodes were harvested in the femoral region, transferred to the axillary region and transplanted by microsurgical procedures.

RESULTS

Lymphedema resolved in 5 out of 6 patients. Pain was relieved in all, permitting return to work and daily activity; analgesic medication was discontinued.

CONCLUSION

This procedure proved efficient and may be advocated in case of neuropathic pain when discussing lymphedema management.

Assessing the impact of pharmacologic intervention on the quality of life in diabetic peripheral neuropathic pain and fibromyalgia

Chronic, neuropathic pain may be secondary to myriad etiologies including diabetic peripheral neuropathy and fibromyalgia. It is a debilitating condition that imposes a significant burden on individuals and society alike. This article will review various instruments designed to assess quality of life (QoL) and key data assessing QoL of patients suffering from these diseases as well as currently available pharmacologic agents for symptomatic management. As basic and clinical science progress over the next few years, along with the introduction of novel pharmacologic agents, we anticipate greater potential for pain intervention and improvement in the quality of life of our patients.

Measuring quality of life in cosmetic and reconstructive breast surgery: a systematic review of patient-reported outcomes instruments

BACKGROUND

Patient-reported outcomes in cosmetic and reconstructive breast surgery are increasingly important for clinical research endeavors. Traditional surgical outcomes, centered on morbidity and mortality, remain important but are no longer sufficient on their own. Quality of life has become a crucial research topic augmenting traditional concerns focused on complications and survival. Given this, reliable and valid patient questionnaires are essential for aesthetic and reconstructive breast surgeons.

METHODS

The authors performed a systematic literature review to identify patient-reported outcome measures developed and validated for use in cosmetic and reconstructive breast surgery patients. Qualifying instruments were assessed for adherence to international guidelines for health outcomes instrument development and validation.

RESULTS

The authors identified 227 health outcomes questionnaires used in breast surgery studies. After 135 generic instruments, 65 ad hoc instruments, seven oncologic instruments, 11 education questionnaires, and two non-English-language questionnaires were excluded, seven measures remained. Detailed analysis revealed that six of the seven measures had undergone limited development and validation. Only one measure, the Breast-Related Symptoms Questionnaire, demonstrated adequate development and validation in its target population. It had, nevertheless, significant content limitations.

CONCLUSIONS

Valid, reliable, and responsive instruments to measure patient-reported outcomes in cosmetic and reconstructive breast surgery are lacking. To demonstrate the benefits of aesthetic and reconstructive breast surgery, future research to rigorously develop and validate new cosmetic and reconstructive breast surgery-specific instruments is needed.

Health related quality of life in different states of breast cancer

OBJECTIVES

The aim of this study was to describe the health related quality of life (HRQoL) in different breast cancer disease states using preference-based measures.

MATERIAL AND METHODS

A total of 361 consecutive breast cancer patients attending the breast cancer outpatient clinic at Karolinska University hospital Solna for outpatient visits between April and May 2005 were included in the study. The EQ-5D self classifier and a direct Time Trade Off (TTO) question were used to estimate the HRQoL in different breast cancer disease states.

RESULTS

Patients in their first year after a primary breast cancer had a mean EQ-5D index value of 0.696 (95% confidence interval (CI): 0.634-0.747)). Patients in their first year after a recurrence had a mean EQ-5D index value of 0.779 (CI: 0.700-0.849). Patients who had not had a primary breast cancer diagnosis or a recurrence during the previous year had a mean EQ-5D index value of 0.779 (CI: 0.745-0.811). Patients with metastatic disease reported the lowest HRQoL values, and had a mean EQ-5D index value of 0.685 (CI: 0.620-0.735). The main driver behind the reduction in HRQoL was pain and discomfort as well as anxiety and depression. TTO values were higher for all diseases states compared to the EQ-5D index values.

CONCLUSION

This study shows that breast cancer is associated with a reduction in HRQoL. This effect is most pronounced for patients with metastatic disease.
