The impact of breast cancer-related lymphedema on rural and small-town Survivors' return-to-work and quality of life: A multiple-case study

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.

Initiating and Maintaining Complete Decongestive Therapy Self-Management of Lymphedema Among Breast Cancer Survivors: Descriptive Qualitative Study

PURPOSE

This study aimed to identify determinants that promote the initiation and maintenance of complete decongestive therapy (CDT) as well as effective strategies for mitigating barriers to self-management of lymphedema among breast cancer survivors.

METHODS

A descriptive and qualitative design was used. In-depth interviews were conducted with 13 breast cancer survivors who were managing breast cancer-related lymphedema. Interviews were transcribed verbatim. An iterative descriptive data analysis method was employed to examine the data, compare codes, challenge interpretations, and inductively identify themes.

RESULTS

A realization that lymphedema requires daily self-management was the primary determinant leading breast cancer survivors to initiate CDT self-management. The determinants for maintaining daily CDT self-management included the perceived effectiveness of CDT, being willing to assume accountability, and perceived efficacy to undertake CDT. Developing strategies to integrate CDT regimens into daily life is key to maintaining CDT self-management of lymphedema. Three core concepts mediate initiation and maintenance of CDT self-management: understanding lymphedema as a chronic condition that can be managed with CDT self-management, being worried about lymphedema exacerbation, and having support from patient peers and family.

CONCLUSIONS

Interventions should be tailored to promote the initiation and maintenance of CDT self-management. While clinicians provided knowledge-based and clinical skills-based information, patient peers provided daily life examples, and real-life implementation strategies for CDT self-management. Ongoing patient-provider and patient-peer communication functioned as effective support for maintaining CDT self-management. Reliable and realistic methods of symptom self-assessment are important for maintaining CDT at home.

The impact of rural structural and community health factors on postmastectomy complications among south central Appalachian breast cancer patients

PURPOSE

The study examined how structural and community health factors, including primary care physicians (PCP), food insecurity, diabetes, and mortality rate per county, are linked to the number and severity of postmastectomy complications among south central Appalachian breast cancer patients depending on rural status.

METHODS

Data was obtained through a retrospective review of 473 breast cancer patients that underwent a mastectomy from 2017 to 2021. Patient's ZIP Code was used to determine their rural-urban community area code and their county of residence for census data. We conducted a zero inflated Poisson regression.

FINDINGS

Results demonstrated that patients in small rural/isolated areas with low (B = -4.10, SE = 1.93, OR = 0.02, p = 0.03) to average (B = -2.67, SE = 1.32, OR = 0.07, p = 0.04) food insecurity and average (B = -2.67, SE = 1.32, OR = 0.07, p = 0.04) to high (B = -10.62, SE = 4.71, OR = 0.00, p = 0.02) PCP have significantly fewer postmastectomy complications compared to their urban counterparts. Additionally, patients residing in small rural/isolated areas with high (B = 4.47, SE = 0.49, d = 0.42, p < 0.001) diabetes and low mortality (B = 5.70, SE = 0.58, d = 0.45, p < 0.001) rates have significantly more severe postmastectomy complications.

CONCLUSION

These findings demonstrate that patients who reside in small/rural isolated areas may experience fewer and less severe postmastectomy when there is certain optimal structural and community health factors present compared to their urban counterparts. Oncologic care teams could utilize this information in routine consult for risk assessment and mitigation. Future research should further examine additional risks for postmastectomy complications.
