Development of a core outcome set for breast cancer-related lymphedema: a Delphi study

PURPOSE

For breast cancer survivors (BCS) living with breast cancer-related lymphedema (BCRL), what outcome domains (OD) should be measured to assess the burden of the disease and efficacy of interventions? A Core Outcome Set (COS) that promotes standardized measurement of outcomes within the constraints of time influenced by work environments is essential for patients and the multidisciplinary professionals that manage and research BCRL.

METHODS

Using Delphi methodology, a multidisciplinary group of BCRL experts (physical and occupational therapists, physicians, researchers, physical therapist assistants, nurses, and massage therapist) completed two waves of online surveys. BCRL expert respondents that completed the first survey (n = 78) had an average of 26.5 years in practice, whereas, respondents who completed the second survey (n = 33) had an average of 24.9 years. ODs were included in the COS when consensus thresholds, ranging from 70% to 80%, were met.

RESULTS

A total of 12 ODs made up the COS. Reaching a minimum consensus of 70%; volume, tissue consistency, pain, patient-reported upper quadrant function, patient-reported health-related quality of life, and upper extremity activity and motor control were recommended at different phases of the BCRL continuum in a time-constrained environment. Joint function, flexibility, strength, sensation, mobility and balance, and fatigue met an 80% consensus to be added when time and resources were not constrained.

CONCLUSION

The COS developed in this study thoroughly captures the burden of BCRL. Using this COS may reduce selective reporting, inconsistency in clinical use, and variability of reporting across interdisciplinary healthcare fields, which manage or research BCRL.

Bibliometric analysis of breast cancer-related lymphedema research trends over the last 2 decades

Objective

As breast cancer cases rise globally, post-mastectomy lymphedema garners increasing scholarly attention. This study aims to conduct a comprehensive bibliometric analysis of Breast Cancer-Related Lymphedema (BCRL) research from 2003 to 2022, identifying trends and providing global research insights for future studies.

Method

The literature for this analysis was extracted from the Web of Science (WoS) Core Collection, encompassing 1199 publications, including 702 articles and 101 reviews, totaling 803. Using advanced bibliometric tools such as VOSviewer and CiteSpace, quantitative and visual analyses were performed to map collaboration networks, research clusters, and emerging trends. The search strategy included specific terms related to lymphedema, breast cancer, and BCRL, ensuring a comprehensive representation of the research landscape.

Results

The bibliometric analysis revealed a steady increase in BCRL publications over the studied period, reaching a peak in 2018. The United States emerged as the leading contributor to BCRL literature, with China also demonstrating a significant presence. Collaboration networks were visualized, showcasing the interconnectedness of institutions and researchers globally. Key research hotspots identified include preventive strategies, complex decongestive therapy, and reconstructive interventions.

Conclusion

In conclusion, this pioneering bibliometric analysis provides a comprehensive overview of BCRL research trends and collaborations globally. The findings contribute valuable insights into the evolution of the field, highlighting areas of focus and emerging research themes. This study serves as a foundational resource for researchers, clinicians, and policymakers, fostering evidence-based practices and interventions for BCRL in the future.

Impact of hand lymphedema on pain and grip strength of the hand in women with breast cancer

Background: It is not clear to what extent signs and symptoms other than arm swelling, including pain, grip strength  differ between women with hand lymphedema and without hand lymphedema in breast cancer–related lymphedema (BCRL)Aim of Study: To estimate the extent to which the impairments associated with hand  lymphedema on pain and grip strength in women with breast cancer related lymphedema (BCRL) and to see the association between severity of hand edema and each of independent variables ( pain and hand grip strength )Methods: sixty women experiencing lymphedema after breast surgery participated in this study. They were recruited from Kasr Al-ainy , between 40: 60 years old were assigned into two equal groups, group (A) women with hand edema (HE+, n = 30) and without hand edema (HE−, n = 30) after breast cancer treatment .Pain and grip strength were evaluated Results: inter group difference showed that there is a there was significant difference in pain difference between the group A and group B (p = 0.04)And there was a significant increase in median value of strength difference of the group A compared with that of group B (p = 0.001).

Sensory signs and symptoms in women with self-reported breast cancer-related lymphedema: a case-control study close up

PURPOSE

It is not clear to what extent signs and symptoms other than arm swelling, including pain, altered sensory function, and body perception disturbances, differ between women with measurable and non-measurable breast cancer-related lymphedema (BCRL). A case-control study was performed to compare these signs and symptoms between (1) women with self-reported BCRL with objectively measurable swelling; (2) women with self-reported BCRL without objective confirmation; and (3) a control group with no self-reported BCRL.

METHODS

The three groups were compared for (1) the severity of self-reported signs and symptoms of BCRL, (2) problems in functioning related to BCRL, (3) pain-related outcomes, (4) sensory functions, and (5) body perception.

RESULTS

All self-reported outcomes related to signs and symptoms of BCRL and problems in functioning were significantly different between the control group and the other two groups with and without measurable self-reported BCRL (p < 0.001-0.003). Except for "skin texture" (p = 0.01), no differences were found between groups. For pain-related outcomes, sensory function, and body perception, significant differences were found for the mechanical detection threshold (p < 0.01) and self-reported disturbances in body perception (p < 0.001) between the self-reported BCRL groups and control group.

CONCLUSIONS

Diverse signs and symptoms related to BCRL, sensory function, and perception were different among women with self-reported BCRL compared to controls. No differences between women with and without measurable self-reported BCRL were found.

IMPLICATIONS FOR CANCER SURVIVORS

The presence of self-reported BCRL, with or without measurable swelling, is a first indication for the need of further diagnostic evaluation.
