Lymphoedema post-mastectomy: is elevation alone an effective treatment?

Area of Science:

• Oncology
• Lymphedema Management
• Post-Mastectomy Rehabilitation

Background:

• Mastectomy, a common breast cancer treatment, can lead to lymphedema, characterized by arm swelling.
• Effective management strategies for post-mastectomy lymphedema are crucial for improving patient quality of life.
• Arm elevation is a non-invasive method explored for fluid reduction in edematous limbs.

Purpose of the Study:

• To investigate the efficacy of arm elevation in reducing arm lymphedema volume following mastectomy.
• To compare fluid reduction in lymphoedematous arms versus control (contralateral) arms.
• To assess the impact of different elevation durations (1 and 5 hours) on fluid removal.

Main Methods:

• A study involving 33 patients who underwent mastectomy.
• Elevation of both lymphoedematous and control arms for 1-hour and 5-hour periods.
• Measurement of arm volume changes to quantify fluid reduction.

Main Results:

• Statistically significant reductions in arm volume were observed in both control and lymphoedematous arms after 1 and 5 hours of elevation (p < 0.05).
• After 1 hour, the control arm showed a greater percentage of fluid removal (2.7%) compared to the lymphoedematous arm (1.3%).
• At 5 hours, there was no significant difference in fluid removal between the control arm (3.3%) and the lymphoedematous arm (3.1%).

Conclusions:

• Arm elevation is an effective intervention for reducing arm lymphedema following mastectomy.
• While initial fluid removal may be greater in non-lymphedematous arms, prolonged elevation (5 hours) leads to comparable fluid reduction in both affected and unaffected arms.
• This suggests arm elevation is a beneficial and accessible method for managing post-mastectomy arm swelling.
