Objective
To investigate the clinical application of axillary peripheral tissue flap during axillary lymph node dissection for breast cancer patients.
Methods
This prospective study involved the clinical data of totally 86 patients with invasive ductal breast cancer who underwent axillary lymph node dissection in Department of Thyroid and Breast Surgery, First People's Hospital of Jingmen City, Hubei Province from March 2014 to March 2015. Forty-one patients were surgically treated with axillary peripheral tissue flap as study group and the remaining 45 patients received no immediate surgical repair as control group. The drainage time,drainage volume, the extent of upper limb dysfunction and patients' satisfaction with axillary appearance and comfort degree were recorded in two groups. Multiple-frequency bioelectrical impedance analysis system was used to determine the ratio of extracellular water to intracellular water in healthy and affected limbs(ECWd/ICWd) so as to reflect the incidence of upper limb lymphedema in postoperative 1 year. The parameters including age, body mass index, number of dissected lymph nodes, number of positive lymph nodes, drainage volume and drainage time, upper limb dysfunction, patients' satisfaction with axillary appearance and comfort degree, and ECWd/ICWd between two groups were compared using t test. The number of lymphatic fistula patients was compared between two groups using χ2 test. Postoperative pathological stage was compared between two groups using rank sum test.
Results
There were no significant differences in age,body mass index, number of dissected lymph nodes, number of positive lymph nodes and postoperative pathological stage between 2 groups (t=-0.216,0.625, -0.504, -0.796, Z=-0.459; P=0.830, 0.534,0.615,0.428,0.647). The drainage volume and drainage time in study group were significantly lower than those in control group [(408.95±49.18) ml vs (458.60±53.88) ml, t=-4.448,P<0.001; (6.49±1.16) d vs (7.11±1.15) d, t=-2.493, P=0.015]. The incidence of lymphatic fistula was 9.76% (4/41) in study group,significantly lower than that in control group (28.9%,13/45) (χ2=4.952,P=0.026). The extent of upper limb dysfunction in study group was significantly lower than that in control group [(3.37±0.69)% vs(3.71±0.81)%, t=-2.099, P=0.039]. The patients' satisfaction with axillary appearance and comfort degree,and ECWd/ICWd in study group were superior to those in control group (7.88±0.90 vs 7.20±0.96,t=3.355, P=0.001;6.98±0.82 vs 6.18±0.80,t=4.544, P<0.001; 1.83±0.21 vs 1.94±0.22,t=-2.257,P=0.027).
Conclusion
The immediate surgical repair using axillary peripheral tissue flap during axillary lymph node dissection can effectively avoid lymphatic fistula, ameliorate upper limb function, improve axillary appearance and comfort and prevent upper limb lymphedema.
