The purpose of this study was to evaluate trajectories of and
predictors for changes in upper extremity (UE) function in women (n = 396) during
the first year after breast cancer treatment. DESIGN:
Prospective, longitudinal
assessments of shoulder range of motion (ROM), grip strength, and perceived
interference of function were performed before and for 1 year after surgery.
Demographic, clinical, and treatment characteristics were evaluated as predictors
of postoperative function. RESULTS: Women had a mean (SD) age of 54.9 (11.6)
years, and 64% were white. Small but statistically significant reductions in
shoulder ROM were found on the affected side over 12 months (P < 0.001).
Predictors of interindividual differences in ROM at the 1-month assessment were
ethnicity, neoadjuvant chemotherapy, type of surgery, axillary lymph node
dissection, and preoperative ROM. Predictors of interindividual differences in
changes over time in postoperative ROM were living alone, type of surgery,
axillary lymph node dissection, and adjuvant chemotherapy. Declines in mean grip
strength from before through 1 month after surgery were small and not clinically
meaningful. Women with greater preoperative breast pain interference scores had
higher postoperative interference scores at all postoperative assessments.
CONCLUSION: Some of the modifiable risk factors identified in this study can be
targeted for intervention to improve UE function in these women.
