“…Based on practical issues and statistical considerations they found it important to keep the size of the LYMQOL small to make it acceptable for users. None of the other translated versions of the LYMQOL have conducted a face validity evaluation of the questionnaire [7,[9][10][11][12][13].…”

“…The LYMQOL is a self-report questionnaire with two versions; one adapted for oedema of the arms with 28 questions and one for oedema of the legs with 27 questions. The LYMQOL leg version has been translated into Dutch and validated [9] and the arm and leg versions have been translated into Turkish and validated by two research groups [10][11][12][13].…”

Background: The aim of this study was to validate a translated Swedish version of the lymphoedemaspecific quality of life questionnaire (LYMQOL) in a cohort of Swedish cancer patients with secondary lymphoedema of the limbs after cancer treatment. Material and methods: We recruited 102 patients with lymphoedema of the arms or legs after cancer treatment who were visiting lymphoedema therapists at the departments of oncology at the university hospitals in Link€ oping and Umeå. The LYMQOL questionnaires were translated forward and backward from English to Swedish. Content and face validity were evaluated. The construct validity was assessed by comparing the LYMQOL with the Short Form Health Survey (SF-36) and the perceived degree of lymphoedema of the limbs, respectively. Reliability was determined through test-retest. The internal consistency was assessed by determining Cronbach's alpha and by factor analysis. Results: The content and face validity assessments showed that LYMQOL was an easy, clear and not too long questionnaire to use for patients with lymphoedema. Construct validity was high in both versions when compared with the SF-36. The association between the degrees of perceived lymphoedema and the LYMQOL was only significant in the domains Function and Body Image in the arm version, whereas all domains in the leg version were significant. The reliability was good for the arm version (intra-class-correlation coefficients 0.53-0.87) and very good for the leg version (intra-class-correlation coefficients 0.78-0.90). The internal consistency was acceptable to excellent, with Cronbach's alpha values between 0.79-0.93 (arm-version) and 0.87-0.94 (leg-version). The factor analysis confirmed the usefulness of the four domains in the LYMQOL versions. Conclusions: This study confirmed the validity of the Swedish version of LYMQOL and demonstrated that LYMQOL may be a simple and useful tool for use in clinical practice and scientific contexts for evaluating QoL in patients with lymphoedema of the limbs.

“…Some tools, such as the Disabilities of Arm Shoulder and Hand questionnaire (DASH), are non-specific and measure the degree of disability resulting from functional changes in the upper extremity resulting from lymphedema [38,39]. Other outcome measures, such as the LLIS, lymphedema quality of life questionnaire (LYMQOL), or the ULL27, have been specifically developed to assess the degree of disability in various scales resulting from lymphedema [24,25,40].…”

Introduction: The purpose of this study was to evaluate the most commonly used preoperative assessment tools for patients undergoing surgical treatment for secondary upper extremity lymphedema. Methods: This was a prospective cohort study performed at a tertiary cancer center specializing in the treatment of secondary lymphedema. Lymphedema evaluation included limb volume measurements, bio-impedance, indocyanine green lymphography, lymphoscintigraphy, magnetic resonance angiography, lymphedema life impact scale (LLIS) and upper limb lymphedema 27 (ULL-27) questionnaires. Results: 118 patients were evaluated. Limb circumference underestimated lymphedema compared to limb volume. Bioimpedance (L-Dex) scores highly correlated with limb volume excess (r2 = 0.714, p < 0.001). L-Dex scores were highly sensitive and had a high positive predictive value for diagnosing lymphedema in patients with a volume excess of 10% or more. ICG was highly sensitive in identifying lymphedema. Lymphoscintigraphy had an overall low sensitivity and specificity for the diagnosis of lymphedema. MRA was highly sensitive in diagnosing lymphedema and adipose hypertrophy as well as useful in identifying axillary vein obstruction and occult metastasis. Patients with minimal limb volume difference still demonstrated significantly impaired quality of life. Conclusion: Preoperative assessment of lymphedema is complex and requires multimodal assessment. MRA, L-Dex, ICG, and PROMs are all valuable components of preoperative assessment.

“…The LYMQoL has been validated in the English and Dutch languages. However, validation of LYMQoL for upper limb lymphedema in the Turkish language has not been performed yet (11). The aim of this study was to translate the English version of LYMQoL to Turkish and to test the reliability and validity of the Turkish version of the questionnaire among patients with BCRL in Turkey.…”

Objective: Breast cancer related lymphedema (BCRL) is a drastic situation that affects patients who have undergone breast cancer surgery. The impact of this condition on individuals' quality of life should be investigated in more detail to obtain better treatment results. Materials and Methods:In total, 65 patients with BCRL participated in this study. Nottingham Health Profile (NHP) was used to evaluate the validity of associated domains in Lymphedema Quality of Life Tool (LYMQoL). Both the LYMQoL and NHP were filled out by BCRL patients. To evaluate its test-retest reliability, the LYMQoL was subsequently performed seven days following its initial application. Measurement properties such as internal consistency, test-retest reliability, criterion validity and factor structure were tested. The internal consistency was assessed via Cronbach's alpha; test-retest reliability was assessed by the intra-class correlation coefficient (ICC). Results:Cronbach's alpha values ranged from 0.74 to 0.91 for the LYMQoL total and domain scores. Test-retest reliability was excellent (ICC=0.92-0.99). When the relation between LYMQoL and NHP was investigated, 'good' to 'very good' correlations were obtained (r=0.539-0.643, p<0.05) for all domains of LYMQoL. Exploratory factor analyses demonstrated a four-factor structure. Conclusion:Turkish version of LYMQoL is a valid and reliable measurement tool to evaluate the quality of life in patients with BCRL.
