Summary

It has been hypothesized that damaged arm lymphatic drainage is associated with the arm lymphedema after axillary lymph node dissection (ALND). However, the majority of breast cancer patients with complete ALND has not suffered from arm lymphedema, which appears to be due to the residual arm lymph nodes that has not been removed in the axillary dissection. With the compensation of the residual arm lymph flow above the level of axillary vein, the arm lymphatic drainage could keep balance and remain normal function. This arm lymphedema prediction model that included the protective factor, the proportion of arm lymph flow above the level of axillary vein, allows intraoperative intervention to be performed for the high-risk group. The arm lymphatics of these distinguished patients would be preserved to eliminate the occurrence of arm lymphedema in this study.

Conditions

• Breast Cancer
• Axillary Lymph Node Dissection
• Breast Cancer Related Lymphedema
• Axillary Reverse Mapping

Interventions

Type	Name	Description
PROCEDURE	Axillary surgery based on lymphedema prediction nomogram	Based on the intraoperative lymphedema prediction nomogram, individualized treatment was recommended to breast cancer patients with different level of risk. For patients with low possibility of developing breast cancer related lymphedema, it was not necessary to preserve arm lymphatics. While the breast cancer patients who were performed mastectomy and ALND with 28 kg/m2 prepared to receive taxane-based chemotherapy, supraclavicular and infraclavicular radiotherapy, according to the established intraoperative nomogram, the proportion of the arm lymph flow above the axillary vein needed to exceed 52%. Otherwise, the arm lymphatics should be identified and preserved.
