Effect of breast conserving surgery on neurotensin and its receptor 1 in patients with breast cancer
2019
Objective
To investigate the effect of breast conserving surgery on neurotensin (NTS) and its receptor 1(NTR1) in patients with breast cancer.
Methods
From May 2012 to May 2015, 200 patients with breast cancer, aged 44.7 years(range, 32-56 years), were treated at Tiantan Hospital, Capital Medical University. All patients were divided into control group (n=100) and observation group (n=100). The patients in the control group were treated with radical operation and the patients in the observation group were treated with breast-conserving surgery. The positive rate of NTS and NTR1 before and 1 week after operation, WHOQOL-100 (It includes four aspects: physiological state, psychological state, environmental condition and social function) 1 d before surgery, 3 months and 6 months after surgery, and the incidence of postoperative complications 1 week after surgery were compared between the two groups. Measurement data with normal distribution were described as mean±standard deviation (Mean±SD) and analyzed by the t test. Count data were analyzed by chi-square test.
Results
The positive rate of NTS (17.00%) in the observation group was significantly lower than that in the control group (36.00%) (t=9.267, P=0.002), The positive rate of NTR1 (19.00%) was significantly lower than that in the control group (33.00%) (t=5.094, P=0.024). The physiological status, psychological state, environmental condition and social function of 3 months after surgery of the observation group were (62.57±5.73), (63.48±5.91), (68.73±6.32), (64.06±5.94) scores, respectively, and the control group were (53.47±5.38), (55.62±5.54), (60.38±6.14), (55.86±5.66) scores, respectively, showing statistically significant differences between the two groups (P<0.05). The physiological status, psychological state, environmental condition and social function of 6 months after surgery were (73.74±6.19), (76.27±6.32), (78.85±6.77), (73.53±6.58) scores in the observation group, and (64.18±5.67), (67.38±6.02), (69.64±6.43), (63.28±6.17) scores in the control group, showing statistically significant differences between the two groups (P<0.05). The incidence of postoperative complications in the observation group (6.00%) was significantly lower than that in the control group (18.00%)(P<0.05).
Conclusion
Breast conserving surgery can reduce the expression level of NTS and NTR1 in breast cancer patients, It is related to reducing the incidence of postoperative complications and improving the quality of life of patients.
