Abstract：Objective To observe the characteristics of affected shoulder joint range of motion in patients with breast cancer after ax-illary lymph node dissection before radiotherapy. Methods From January,2022 to December,2023,185 female patients from the Fourth Hospital of Hebei Medical Uni-versity after unilateral breast cancer who underwent axillary lymph node dissection were reviewed.Their general data were collected;affected shoulder joint range of motion was evaluated by progoniometer;lymphedema of af-fected upper extremities was evaluated by water volume replacement;Verbal Rating Scale(VRS)was used to evaluate the pain in the upper extremity of the operative side. Results The angles of anterior flexion and abduction of the affected shoulder joint were(158.90±17.17)° and(147.70±24.59)°.There were significant differences in the angles of affected shoulder anterior flexion and abduction among patients at different ages(more than 55 years and less than 55 years)and those with or without lymphede-ma.Multiple linear regression showed that the angle of affected shoulder flexion was smaller in patients aged more than 55 years(β=-7.766,95%CI-13.161 to-2.360,P=0.005),and with lymphedema(β=-10.991,95%CI-19.063 to-2.925,P=0.008);was larger in patients with longer duration after operation(β=0.463,95%CI 0.012 to 0.924,P=0.049),and BMI 24 to 27.9 kg/m2(β=6.211,95%CI 0.660 to 11.761,P=0.030)(compared with BMI<24 kg/m2).The angle of affected shoulder abduction was smaller in patients aged more than 55 years(β=-10.047,95%CI-17.358 to-2.747,P=0.008),and with lymphedema(β=-14.171,95%CI-25.191 to-3.150,P=0.013). Conclusion Shoulder joint range of motion has reduced in flexion and abduction in patients at early stage after axillary lymph node dissection for breast cancer,which is related to age and lymphedema.
