Effects of implantation of pectoralis major fascia combined with serratus anterior fatty fascia flap prosthesis on breast reconstruction after early breast cancer surgery / 肿瘤研究与临床

ABSTRACT

Objective:To investigate effects of implantation of pectoralis major fascia combined with serratus anterior fatty fascia flap prosthesis on breast reconstruction after early breast cancer surgery.Methods:A total of 62 patients with early breast cancer undergoing breast reconstruction in Dongguan People's Hospital of Guangdong Province from July 2017 to December 2019 were selected and randomly divided into two groups, 31 cases in each group. The control group was treated with pectoralis major fascia covering prosthesis for breast reconstruction, and the observation group was treated with pectoralis major fascia combined with serratus anterior fatty fascia flap covering prosthesis for breast reconstruction. The clinical data of the two groups were recorded, the postoperative aesthetic appearance of breast was evaluated. According to the function assessment of cancer therapy-breast cancer (FACT-B) was used to evaluate the score of quality of life before and after operation, and postoperative complications were also observed.Results:In the control group and the observation group, the intraoperative blood loss was (82.61±12.38) ml, (88.76±13.57) ml, respectively; and drainage tube extubation time was (3.51±0.62) d and (3.64±0.58) d, respectively; there was no statistically significant difference between the two groups ( t value was 1.864, 0.853, respectively, all P > 0.05). The operation time of the observation group was longer than that of the control group [(2.59±0.29) h vs. (1.72±0.32) h, t = 11.217, P < 0.001]. The amount of drainage of the control group was higher than that of the observation group [(215.45±47.69) ml vs. (151.36±31.67) ml, t = 6.233, P < 0.001]; the length of hospital stay of the control group was longer than that of the observation group [(14.51±2.32) d vs. (10.79±1.86) d, t = 6.965, P < 0.001]. The excellent and good rate of postoperative breast appearance of the observation group was higher than that of the control group [96.77% (30/31) vs. 74.19% (23/31), χ 2adjusted=4.679, P = 0.031]. There were no statistical differences in all items including health, emotion, function, society/family and other conditions scores of FACT-B and total scores in both groups before the operation (all P > 0.05); all items scores and total scores of both groups after the operation were higher than those before the operation (all P < 0.001), and the sores after the operation of the observation group were higher than those of the control group (all P < 0.001). The total incidence of postoperative complications was 6.45% (2/31) of the observation group, 22.58% (7/31) of the control group, and the difference was not statistically significant (χ 2adjusted=2.080, P = 0.149). Conclusion:Breast reconstruction with implantation of pectoralis major fascia combined with serratus anterior fatty fascia flap prosthesis after early breast cancer surgery can shorten the postoperative hospital stay, improve the aesthetic appearance of breast, improve the long-term quality of life, and has a high safety.
