Effect of Lymphedema Prevention Program Based on Theory of Knowledge-attitude-practice on Postoperative Breast Cancer Patients

Not Applicable

Completed

• Conditions: Breast Cancer Lymphedema
• Interventions: Behavioral: Lymphedema prevention protocols

• Registration Number: NCT05595330
• Lead Sponsor: First Affiliated Hospital Xi'an Jiaotong University

Brief Summary

According to the inclusion and exclusion criteria, a total of 108 patients were enrolled and randomly divided into control group (n = 56) and intervention group (n = 52). The control group received routine nursing, while the intervention group received upper limb lymphedema prevention program for breast cancer patients after surgery. Before surgery, at the third chemotherapy (about 2.1 months after surgery) and the sixth chemotherapy (about 4.2 months after surgery), the self-designed general information questionnaire was used to investigate the patient's basic situation, and the corresponding tools were used to measure the volume of the patient's upper arm, the grip strength of the affected arm, and the range of motion of the affected shoulder joint.

Arm && Interventions

Group	Intervention	Description
intervention group	Lymphedema prevention protocols	Patients in the intervention group were managed with an upper extremity lymphedema prevention program.

Primary Outcome Measures

Name	Time	Method
Changes in breast cancer-related lymphedema at baseline,9 weeks after surgery,and 18 weeks after surgery	Baseline-9 weeks after surgery-18 weeks after surgery	Use an inelastic, flexible soft ruler to measure the circumference at 5 positions on the flat wrist crease, 0cm, 10cm, 20cm, 30cm, and 40cm on the wrist crease. The upper limb can be divided into 4 truncated cones, and the measured value is accurate to 0.1 cm. The upper arm volume is calculated using the formula , each h is 10 cm, C1 and C2 are the circumferences next to the two measurement points, and then add up the limb volumes at several positions to get the upper arm volume.; According to the International Society of Lymphoma, a volume difference of 10% or more is defined as lymphedema, less than 20% is mild lymphedema, 20% - 40% is moderate lymphedema, and greater than 40% is defined as severe lymphedema.; Change(Baseline-9 weeks after surgery-18 weeks after surgery)

Secondary Outcome Measures

Name	Time	Method
Changes in grip strength at baseline,9 weeks after surgery,and 18 weeks after surgery	Baseline-9 weeks after surgery-18 weeks after surgery	The grip strength of the affected side was measured with the help of electronic grip strength meter. Test method: The patient stands straight with the arm down and the affected hand grasps the grip strength meter with force. Two measurements were taken and the average was taken.; Change(Baseline-9 weeks after surgery-18 weeks after surgery)
Change in Arm disability at baseline,9 weeks after surgery,and 18 weeks after surgery	Baseline-9 weeks after surgery-18 weeks after surgery	The Chinese version of the DASH scale, adapted from the DASH scale developed by Beaton, was used to assess the upper limb condition of the patients. Cronbach's A coefficient was 0. 911, and the intra-group correlation coefficient was 0. 882, which had good reliability and validity. The highest score is 100 and the lowest is 0, with higher scores indicating more severe upper arm problems.; Change(Baseline-9 weeks after surgery-18 weeks after surgery)
Changes in Shoulder range of motion at baseline,9 weeks after surgery,and 18 weeks after surgery	Baseline-9 weeks after surgery-18 weeks after surgery	The range of motion (ROM) of the upper limb of breast cancer patients was measured with a circular goniometer (0°-360°) . The rehabilitation technician measured the upper limb mobility in six directions: forward flexion, back extension, abduction, adduction, internal rotation, and external rotation.; Change(Baseline-9 weeks after surgery-18 weeks after surgery)
Change in Quality of life at baseline,9 weeks after surgery,and 18 weeks after surgery	Baseline-9 weeks after surgery-18 weeks after surgery	Quality of life was evaluated using Functional Assessment of Cancer Therapy Questionnaire for Breast Cancer, which was developed by Cella. It was translated into Chinese by Wan and the Cronbach 'α for each sub-scale was 0.61-0.84.The questionnaire had 36 items classified into five dimensions and all the items were measured with a 5-point Likert scale, The highest score is 144 and the lowest is 0,with higher scores indicating higher levels of quality of life.; Change(Baseline-9 weeks after surgery-18 weeks after surgery)
