Assessment of health-related quality of life in patients with lymphedema of the lower limb

Health-related quality of life and associated factors in patients with primary lymphedema

AIM

Primary lymphedema requires continuous conservative treatment during the patient's life, which may affect their health-related quality of life (HRQOL). Physical and psychosocial characteristics related to lymphedema are associated with their HRQOL. This study aimed to assess HRQOL in those patients undergoing conservative treatment and to determine the factors associated with their HRQOL.

METHODS

This was a cross-sectional, observational study that included 83 patients with primary lymphedema at an outpatient clinic for lymphedema. HRQOL was assessed with the Medical Outcomes Study 36-Item Short Form Survey (SF-36) and EuroQol 5-Dimension (EQ-5D). Lymphedema status/complications and psychosocial status were evaluated by medical records, physical assessment, and self-administrative questionnaires.

RESULTS

The general health perception score in the SF-36 was lower than the age- and sex-stratified national norms (P = 0.001). In the EQ-5D, the proportions of patients with some/moderate or severe problems were 42.2% for pain/discomfort, 21.7% for usual activities, and 20.5% for anxiety/depression. By multiple regression analyses, a lower physical component summary score in the SF-36 was associated with a higher lymphedema stage (P = 0.021), cellulitis within 30 days (P = 0.003), exercise (P = 0.010), and more substance use coping (P = 0.012). A lower mental component summary score was associated with skin lesions over edematous limbs (P = 0.008), less humor coping (P = 0.005), and more self-blame coping (P = 0.014).

CONCLUSION

Patients with primary lymphedema have problems in health perception, discomfort, usual activities, and anxiety/depression. Preventing cellulitis and skin lesions and humor coping may be able to improve HRQOL.

Prevalence of lymphoedema and quality of life among patients attending a hospital-based wound management and vascular clinic

Lymphoedema is a chronic, incurable, debilitating condition, usually affecting a limb and causes discomfort, pain, heaviness, limited motion, unsatisfactory appearance and impacts on quality of life. However, there is a paucity of prevalence data on this condition. This study aimed to determine the prevalence of lymphoedema among persons attending wound management and vascular clinics in an acute tertiary referral hospital. Four hundred and eighteen patients meeting the inclusion criteria were assessed. A prevalence rate of 2.63% (n = 11) was recorded. Thirty-six percent (n = 4) had history of cellulitis and broken skin, 64% (n = 7) had history of broken skin and 36% (n = 4) had undergone treatment for venous leg ulcers. The most common co-morbidities were hypertension 55% (n = 6), deep vein thrombosis (DVT) 27% (n = 3), hypercholesterolemia 36% (n = 4) and type 2 diabetes 27% (n = 3). Quality of life scores identified that physical functioning was the domain most affected among this group. This study has identified the need to raise awareness of this condition among clinicians working in the area of wound management.

Surgical management of lymphedema: past, present, and future

Recent advances in surgical management of lymphedema have provided options for patients who have failed conservative management with manual lymphatic massage and/or compression garments. The purpose of this review is to provide a historical background to the surgical treatment of lymphedema and how these options have evolved over time. In addition, we aim to delineate the various types of surgical approaches available, indications for surgery, and reported outcomes. Our goal is to increase awareness of these options and foster research to improve their outcomes.

(18)F-FDG PET/CT in a rare case of Stewart-Treves syndrome: future implications and diagnostic considerations

BACKGROUND

The aim of this article is to illustrate the possible applications of (18)F-fluorodeoxyglucose positron emission tomography/computer tomography ((18)F-FDG PET/CT) in chronic extremity lymphedema and its complications.

METHODS AND RESULTS

(18)F-FDG PET/CT findings in a rare case of Stewart-Treves Syndrome (STS), angiosarcoma secondary to chronic extremity lymphedema, are presented. Lymphedema of the extremities is a debilitating disease characterized by chronic swelling due to interstitial edema caused by insufficient lymphatic drainage capacity. Progression with skin thickening, subcutaneous fibrosis, and increased adipose tissue volume is common. Chronic inflammation has been suggested as a key pathophysiologic component. STS is a rare complication with a very poor prognosis; however, early diagnosis and radical treatment is associated with increased survival. Thus, accurate pretreatment staging is paramount. (18)F-FDG PET/CT is highly sensitive in detecting increased glucose metabolism as seen in many types of cancer and inflammation. The role of (18)F-FDG PET/CT in the management of lymphedema and its complications has to our knowledge yet to be described. This case documents high (18)F-FDG uptake in STS, but is at the same time an example of the low specificity of this imaging modality.

CONCLUSIONS

We suggest that (18)F-FDG PET/CT has the potential to become an important tool in the staging and treatment planning of Stewart-Treves syndrome. Furthermore, (18)F-FDG-accumulation may be a sensitive tool in detecting low grade inflammation in the skin and subcutis, which has been suggested to cause tissue remodeling in lymphedema progression. However, further studies are needed to elucidate this theory.

Primary lower limb lymphedema: a focus on its functional, social and emotional impact

Primary lymphedema is a rare, chronic and distressing condition with negative effects on physical, social and emotional level. The purpose of these reports was to present and discuss two different cases of primary lower limb lymphedema with a focus on its physical and mental impact and on some qualitative aspects of patients' self-reported experiences. The patients were recruited as they used occasional services within the University Hospital of Heraklion (Crete, Greece). The functional and mental impact of primary lymphedema was measured using the generic Medical Outcome Study short form-36 questionnaire and open-ended questions led to give more emphasis to patients' experiences. The analysis of short form-36 results in the first patient disclosed a significant functional impairment with a minor impact of the condition on emotional and social domains. For the second patient quality of life scores in the emotional and social domains were affected. Our findings support further the statement that physicians should pay full attention to appraise the patient's physical and emotional condition. General practitioners have the opportunity to monitor the long-term impact of chronic disorders. Posing simple open-ended questions and assessing the level of physical and mental deficits in terms of well-being through the use of specific metric tools can effectively follow-up rare conditions in the community.

Quality of life after surgical reduction for severe primary lymphoedema of the limbs and genitalia

Background

The aim was to assess the quality of life (QoL) of patients who had surgery for primary lymphoedema.

Methods

A QoL questionnaire was administered to patients who had surgery between 1981 and 2003 (retrospective group) and between 2003 and 2006 (prospective group).

Results

The response rate was 70·3 per cent (109 of 155 patients): 88 patients had limb reduction (78, retrospective; ten, prospective) and 21 had genital reduction (13, retrospective; eight, prospective). Forty-nine patients (63 per cent) who had limb reduction studied retrospectively reported satisfaction with the procedure and most of these would opt for surgery again. In the prospectively studied group, nine of ten patients reported improved limbs, and seven would opt for surgery again. Nineteen of 21 patients who had genital reduction would choose to have surgery again if needed (11 of the retrospectively assessed group and all of the prospective group). Patients' perception that surgery was worthwhile was greater in both of the prospectively assessed groups (P = 0·013).

Conclusion

Surgery for severe lymphoedema improved QoL at early assessment. This, however, may not be sustained. Genital reduction appeared to provide greater benefit than limb reduction.

Lymphedema and quality of life in breast cancer survivors: the Iowa Women's Health Study

PURPOSE

The impact of lymphedema or related arm symptoms on health-related quality of life (HRQOL) in breast cancer (BrCa) survivors has not been examined using a large population-based cohort.

PATIENTS AND METHODS

The Iowa Women's Health Study (IWHS) collected self-report data for lymphedema, arm symptoms, and HRQOL (Medical Outcomes Study Short Form-36) in 2004 and data for cancer diagnosis, treatment, and behavioral and health characteristics between 1986 and 2003. We studied 1,287 women, age 55 to 69 years at baseline, who developed unilateral BrCa. We used cross-sectional analyses to describe the prevalence of lymphedema and arm symptoms and multivariate-adjusted generalized linear models to compare HRQOL (physical functioning, bodily pain, general health, physical and emotional role limitations, vitality, social functioning, and mental health) between the following three survivor groups: women with lymphedema (n = 104), women with arm symptoms without diagnosed lymphedema (n = 475), and women without lymphedema or arm symptoms (n = 708).

RESULTS

The mean (+/- SE) time between BrCa diagnosis and lymphedema survey was 8.1 +/- 0.2 years. Of BrCa survivors, 8.1% self-reported diagnosed lymphedema, and 37.2% self-reported arm symptoms. Knowledge of lymphedema was low among survivors without diagnosed lymphedema (n = 1,183). After multivariate adjustment, women with diagnosed lymphedema or arm symptoms without diagnosed lymphedema had lower physical and mental HRQOL compared with women without lymphedema or arm symptoms. Effect sizes were mild to moderate. There was a dose-response relation between number of arm symptoms and lower HRQOL.

CONCLUSION

In the IWHS, HRQOL was lower for BrCa survivors with diagnosed lymphedema and for those with arm symptoms without diagnosed lymphedema. Clinical trials are needed to determine what interventions can improve lymphedema and impact HRQOL for BrCa survivors.

Quality of life assessment tools in chronic oedema

Chronic oedema can significantly impair a person's quality of life (QoL). QoL assessment tools can be used in routine clinical practice or in research projects e.g. clinical trials. The characteristics of the different types of tool are discussed. A number of QoL measures have been used in studies of chronic oedema both generic instruments such as SF-36 and condition-specific tools e.g. ULL-27. Currently there is no standard validated QoL tool for chronic oedema used in routine clinical practice in the UK to assess individuals, plan care and measure the outcome of treatment. Possible options for this are considered.

Effects of complex decongestive physiotherapy on the oedema and the quality of life of lower unilateral lymphoedema following treatment for gynecological cancer

There is increasing interest in the health-related quality of life (QOL) of patients with chronic lymphoedema. The purpose of the present study was to ascertain whether or not complex decongestive physiotherapy (CDP) for 57 gynecological cancer patients with unilateral lymphedema results in a measurable change in the oedema and QOL, and % excess volume correlated with change in QOL. % excess volume was significantly (P<0.05) decreased after CDP. The QOL scores were significantly (P<0.05) higher than the scores at baseline, indicating an improvement in the QOL. The change in % excess volume was associated with a change in physical functioning, social functioning, role-physical, bodily pain and general health at baseline and 1 month (P<0.05). This study suggests that significant improvements are made in the QOL of gynecological cancer patients with unilateral lymphoedema after CDP, which is necessarily correlated with limb reduction.

Uncommon leg ulcers in the lower extremity

OBJECTIVE

To determine the prevalence of uncommon ulcers, unrelated to venous or arterial etiology, in patients presenting to vascular clinics.

METHODS

This was a multicenter prospective study of consecutive patients presenting with lower extremity ulceration. The settings were university hospital outpatient centers and venous clinics. A total of 799 limbs in 710 patients with leg ulcers were evaluated. Patients with venous ulcer disease and with evidence of arterial disease with an ankle-brachial index less than 0.7 were excluded from the study. Out of 710 patients, 17 patients with a total of 21 limbs fit the criteria for inclusion. All limbs included in this study underwent physical examination, ankle-brachial index measurements, duplex ultrasonography, and skin biopsies.

RESULTS

The mean age of patients with uncommon ulcers was 65.6 years, and the mean duration was 5.5 years. A total of 2.1% of all leg ulcers seen were due to uncommon etiology unrelated to venous or arterial pathology. Most of these ulcers were located in the medial lower calf (n = 19). In six patients with ulcers, the histology did not reveal any specific cause; five had a neoplasia, three had chronic inflammation, two had sickle cell disease, two had vasculitis, one had rheumatoid arthritis, one had pyoderma gangrenosum, and one had ulcer due to hydroxyurea.

CONCLUSIONS

The prevalence of leg ulcers unrelated to arterial and venous disease that presented with signs and symptoms of chronic venous disease was 2.1%. Their etiology is variable, most often including vasculitis, neoplasia, metabolic disorders, infection, and other rare causes. Early identification of uncommon ulcers may facilitate timely and appropriate management.
