Composite incidence of deep vein thrombosis (DVT) of the lower extremities and pulmonary embolism (PE). DVT is diagnosed by bilateral lower extremity venous color Doppler ultrasonography performed on postoperative day 3, before discharge, and at 1, 3, and 6 months postoperatively or when clinically indicated. PE is evaluated by computed tomography pulmonary angiography (CTPA) when clinically suspected.

Diagnosis based on International Society of Lymphology criteria (Grade I: pitting edema relieved by elevation; Grade II: non-pitting edema with tissue fibrosis; Grade III: elephantiasis). Measured by bilateral calf circumference (thickest point) and thigh circumference (15 cm above patella).

Change in the Global Health Status / Quality of Life subscale score from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Minimum value: 0. Maximum value: 100. Higher scores indicate better quality of life.

Measured by the Newcastle Satisfaction with Nursing Scale (NSNS). Categorized as: highly satisfied, moderately satisfied, or not satisfied. Overall satisfaction rate = (highly satisfied + moderately satisfied) / total patients × 100%.

Change in hemoglobin (Hb) measured from complete blood count, reported in g/L.

Change in the Functional Scales composite score from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Minimum value: 0. Maximum value: 100. Higher scores indicate better functional status.

Change in the Symptom Scales composite score from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Minimum value: 0. Maximum value: 100. Higher scores indicate worse symptom burden.

Change in the Single Items score (including dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties) from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Minimum value: 0. Maximum value: 100. Higher scores indicate worse symptom burden or greater financial difficulty.

Change in the total score from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Minimum value: 0. Maximum value: 100. Higher scores indicate better overall quality of life.
