Seated group: After randomization, participants receive docetaxel infusion in a seated position in a reclining chair during all 4 cycles of docetaxel therapy. The backrest angle may be adjusted for patient comfort, but both lower limbs are kept dependent toward the floor during infusion. The docetaxel dose, infusion time, premedication, fluid administration, supportive care, and usual care are determined by the attending physician and institutional practice. Compression therapy, dietary guidance, diuretics, or other edema- or fluid-related management are not specified as study interventions.
Supine group: After randomization, participants receive docetaxel infusion in a supine position on a bed during all 4 cycles of docetaxel therapy. The trunk and lower limbs are kept approximately horizontal. Use of a pillow is allowed, but additional cushions for the purpose of lower-limb elevation are not used. The docetaxel dose, infusion time, premedication, fluid administration, supportive care, and usual care are determined by the attending physician and institutional practice. Compression therapy, dietary guidance, diuretics, or other edema- or fluid-related management are not specified as study interventions.

Male and Female
-Patients who have received sufficient explanation and provided written informed consent voluntarily
-Patients who are 18 years or older at the time of consent
Patients will be excluded if they meet any of the following conditions:
-Presence of lower limb lymphedema
-Diagnosed with conditions that may cause edema:
Deep vein thrombosis of the lower limbs
Severe cardiac or pulmonary disease
Severe hepatic or renal dysfunction
Other metabolic disorders
-Implanted pacemaker
-Unable to maintain posture required for ultrasound examination
-Any other reason deemed inappropriate by the principal or co-investigators
Rationale: To exclude confounding causes of edema and ensure safety and data validity.
