This trial studies how an investigational surgical procedure called vascularized lymph node transfer works in lowering the risk of arm swelling (lymphedema) in patients with breast cancer undergoing breast reconstruction. Patients who undergo breast reconstruction are often at high risk of developing lymphedema. Vascularized lymph node transfer involves transferring lymph nodes from an unaffected area of the body to replace those removed as part of treatment, which may lower the risk of lymphedema after breast reconstruction.
PRIMARY OBJECTIVE: I. Determine incidence of patients who develop lymphedema following autologous breast reconstruction. SECONDARY OBJECTIVES: I. Determine the overall complications of prophylactic vascularized lymph node transfers. II. Compare the incidence of patients who develop lymphedema following autologous breast reconstruction among patients who had prophylactic lymph node transfer and a historical cohort who did not have prophylactic lymph node transfer. OUTLINE: Patients undergo vascularized lymph node transfer during standard of care breast reconstructive surgery. After completion of study, patients are followed up for 3 weeks, at 3 and 6 months, and then at 1 and 2 years.

Incidence rate of lymphedema development
Summary statistics such as means, standard deviations, median and range for continuous variables, and frequencies and percentages for categorical variables will be reported. The rate of lymphedema and its 95% exact confidence interval will be estimated.
Time frame: At 12 months after surgery
Time to lymphedema development
Will be estimated by the Kaplan-Meier method.
Time frame: Up to 2 years
Incidence rate of lymphedema development
The incidence of lymphedema between patients who undergo vascularized lymph node transfer (VLNT) and historical cohorts who do not will be compared. The inverse probability of treatment weighting using the propensity scores will be applied to estimate the effect of VLNT.
Time frame: Up to 2 years
Complications of prophylactic VLNT
Overall complications will include infections, dehiscence, hematoma, seroma and flap compromises. The 95% exact confidence interval will be estimated.
Time frame: Within 30 days after surgery
