Healthcare Practitioners' Knowledge of Lymphedema

Assessing breast cancer-related lymphedema screening and treatment gaps in a safety-net hospital

BACKGROUND AND OBJECTIVES

We evaluated the unmet breast cancer-related lymphedema (BCRL) treatment and education needs at New England's largest safety-net hospital serving a diverse population by assessing prevalence, risk factors, and treatment.

METHODS

This was a retrospective cohort study examining breast cancer surgery patients from September 2016 to September 2021. The primary outcome was BCRL diagnosis. Secondary outcomes included BCRL risk factors, and physical and occupational therapy (PT/OT) referral frequency and completion.

RESULTS

Of 639 patients, 17% of patients had documented BCRL, which was significantly associated with axillary lymph node dissection (ALND). There were no racial, insurance, breast radiation, or BMI category differences between patients with and without a BCRL diagnosis. Of those with BCRL, 58% received a PT/OT referral, and 56% completed their referral. There were no racial, insurance, or BMI category differences between those who received a PT/OT referral and those who did not.

CONCLUSION

In our high-risk population, rates of documented BCRL were higher than expected, approaching rates of ALND, despite the majority undergoing sentinel lymph node biopsy (SLNB). PT/OT referral and completion rates were low, concerning for an unmet BCRL treatment and education need. No disparities in care delivery were seen, but a program that addresses treatment gaps and ensures accessible and patient-centered BCRL care is urgently needed.

Lymphedema after saphenous harvesting for coronary artery bypass surgery: case report and literature review

Different causes have been described for secondary lymphedema as reported in this article. A 75-year-old man was diagnosed with lymphedema about one decade after saphenous harvesting for coronary artery bypass surgery. It took two years for him to find out his diagnosis and receive the proper treatment. After standard complete decongestive therapy, his volume and pain decreased and his quality of life was improved, especially its physical aspect. It is important to recognize the possibility of lymphedema development after saphenous harvesting among patients undergoing coronary artery bypass surgery to prevent significant disturbance of quality of life with timely management.

Analysis of the Risk Factors of Breast Cancer-Related Lymphedema and Construction and Evaluation of a Prediction Model

Objective: The occurrence of breast cancer-related lymphedema (BCRL) in postoperative breast cancer survivors is described and the independent risk factors of BCRL are analyzed. A BCRL nomogram prediction model is constructed, and its effectiveness is evaluated to screen out high-risk patients with BCRL. Methods: A univariate analysis was carried out to determine the risk factors possibly related to BCRL, and a logistic regression analysis was utilized to determine the independent risk factors related to BCRL. A BCRL nomogram prediction model was built, and a nomogram was drawn by R software v4.1.0. The area under the curve (AUC) of the receiver operating characteristic (ROC) and the Hosmer-Lemeshow test were used to evaluate the efficacy of the constructed model to assess its clinical application value. Results: The risk factors independently associated with BCRL were body mass index (BMI), handedness on the operation side, no BCRL-related rehabilitation plan, axillary lymph node dissection (ALND), taxane-based chemotherapy, and radiotherapy (all p < 0.05). The BCRL nomogram prediction model was built on this basis, and the results of the efficacy evaluation showed a good fit: AUC = 0.952 (95% confidence interval: 0.930-0.973) for the ROC and χ2 = 6.963, p = 0.540 for the Hosmer-Lemeshow test. Conclusions: The risk factors for BCRL included higher BMI, handedness on the operation side, no BCRL-related rehabilitation plan, ALND, taxane-based chemotherapy, and radiotherapy. In addition, the BCRL nomogram prediction model accurately calculated the risk of possible BCRL among breast cancer survivors and effectively screened for high-risk patients with BCRL. Therefore, this prediction model can provide a basis for rehabilitation physicians and therapists to formulate early and individualized prevention and treatment programs.

Breast cancer survivors' experiences of barriers and facilitators to lymphedema self-management behaviors: a theory-based qualitative study

PURPOSE

Lifelong self-management plays a critical role in the prevention and management of lymphedema among breast cancer survivors. However, adherence to lymphedema self-management behaviors has remained suboptimal. Hence, we adopted a theory-informed method to elucidate the facilitators and barriers of lymphedema self-management for breast cancer survivors.

METHODS

In-depth semi-structured interviews were conducted between August and October 2022 in the lymphedema nursing clinic of a tertiary cancer hospital. The maximum variation sampling technique was used to ensure a diverse sample. The ITHBC (Integrated Theory of Health Behavior Change) framework was used to inform the interview outline and data analysis. Interview transcripts were coded line-by-line and mapped to domains in accordance with the ITHBC, using both deductive and inductive content analysis.

RESULTS

A total of 16 participants were interviewed (aged 35 to 67). Twenty-three themes (12 facilitators and 11 barriers) were mapped onto the three domains (knowledge and belief, social facilitation, and self-regulation skill and ability) of ITHBC as facilitators and barriers to lymphedema self-management. Three additional themes including limited treatment resources for lymphedema, inconvenience of lymphedema management, boredom and tedium of lymphedema self-management were categorized under the domain of other barriers.

CONCLUSIONS

Incorporating these findings into the ITHBC framework allows for a more systematic selection of theory-based strategies that may improve the design of effective lymphedema self-management interventions for breast cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Elucidating impact factors, especially facilitators and barriers, for lymphedema self-management adherence is essential for developing effective intervention programs to enhance breast cancer survivors' lymphedema self-management behaviors.

The Lymphatic System, Lymphoedema, and Medical Curricula-Survey of Australian Medical Graduates

The aim of this study was to survey the perceptions of recent (i.e., within the past 12 months) Australian medical graduates regarding (i) their understanding of the lymphatic system and lymphoedema, and (ii) the extent to which the lymphatic system and lymphoedema were covered as part of their medical degree. Medical graduates were invited to participate in a 17-item online survey that asked respondents to rate their level of agreement (using a 5-point Likert scale; higher scores = higher agreement) to statements that explored their understanding and comprehensiveness of their medical degree. Responses to each item were described using n (%). Subscale scores for understanding and medical degree were computed by summing scores of individual items, described using means (SD) and compared by participant characteristics. Medical graduates (n = 230) perceived their understanding of the lymphatic system and lymphoedema to be low, and comprehensiveness of medical curricula specific to the lymphatic system and lymphoedema to be lacking. Subscale scores did not differ by participant characteristics. Improvement of medical graduates understanding of lymphoedema may facilitate greater awareness of lymphoedema, thus optimizing the timeliness of diagnosis and access to treatment.
