Abstract

BACKGROUND:

 Lymphedema is a feared complication of breast cancer surgery. We evaluated the trends in lymphedemadevelopment, patient worry, and risk reduction behaviors.

STUDY DESIGN:

 We prospectively enrolled 120 women undergoing sentinel node biopsy (SLNB) or axillary node dissection (ALND) for breast cancer and assessed lymphedema by upper extremity volume preoperatively and at 6 and 12 months postoperatively. We defined lymphedema as a >10% volume change from baseline relative to the contralateral upper extremity. Patients completed a validated instrument evaluating lymphedema worry and risk reducing behaviors. Associations were determined by Fisher's exact and signed rank tests.

RESULTS:

 At 6 months, lymphedema was similar between ALND and SLNB patients (p = 0.22), but was higher in ALND women at 12 months (19% vs 3%, p = 0.005). A clear relationship exists between relative change in upper extremity volume at 6 and 12 months (Kendall tau coefficient 0.504. Among the women with 0 to 9% volume change at 6 months, 22% had progressive swelling, and 18% resolved their volume changes at 12 months. Overall, 75% of ALND and 50% of SLNB patients had persistent worry about lymphedema at follow-up, and no difference existed in the number of risk reducing behaviors practiced among the 2 groups.

CONCLUSIONS:

 Upper extremity volumes fluctuate, and there is a period of latency before development of lymphedema. Despite the low risk of lymphedema after SLNB, most women worry about lymphedema and practice risk reducing behaviors. Additional study into early upper extremity volume changes is warranted to allay the fears of most women and better predict which women will progress to lymphedema.

Purpose

Lymphedema of the arm is a potential complication of breast cancer therapy. This study examines pre-disposing factors that may operate in conjunction with treatment-related factors in the development of arm lymphedema in a large cohort of White and Black breast cancer survivors. Methods 494 women (271 White and 223 Black) with in situ to Stage III-A primary breast cancer completed a baseline interview within 18 months of diagnosis. Information on lymphedema was collected during a follow-up interview, conducted on average 50 months after diagnosis. Self-reported data were used to classify women with or without lymphedema. Multivariable logistic regression models were developed to identify risk factors for arm lymphedema. Results Arm lymphedema was associated with younger age at diagnosis (odds ratio, OR per year of age = 0.96; 95% confidence interval, CI = 0.93-0.99), positive history of hypertension (OR = 2.31; 95% CI = 1.38-3.88), obesity (OR for body mass index, BMI>/=30 = 2.48; 95% CI = 1.05-5.84) and having had surgery where 10 or more lymph nodes were excised (OR = 2.16; 95% CI = 1.12-4.17). While Black women had higher prevalence of arm lymphedema than White women (28% vs. 21%), race was not associated with lymphedema risk in models adjusted for multiple factors (adjusted OR = 1.01; 95% CI = 0.63-1.63). Conclusion Risk of arm lymphedema did not differ significantly for Black and White women. Risk factors identified in this study offer opportunities for interventions (weight loss, control of blood pressure, use of sentinel node biopsy where possible) for reducing incidence of lymphedema or controlling the symptoms associated with this condition.
