Influence of different chemotherapies on the immunological function and part of the quality of life of patients with breast cancer / 中国综合临床

ABSTRACT

Objective To explore the influence of TAC protocol (pirarubicin,cyclophosphamide and docetaxel) and AC-T protocol (pirarubicin,cyclophosphamide and sequential docetaxel) on T lymphocytes cell subsets (included CD3+ T cells,CD3+ CD4+ T cells,CD3+ CD8+ T cells,CD3+ CD4+/CD3 + CD8+),natural killer (NK) cells and part of the quality of life in the peripheral blood of patients.Methods A total of 66 patients with breast cancer included 31 cases for TAC protocol (6 cycles of chemotherapy) and 35 cases for AC-T protocol(8 cycles of chemotherapy).Collected respectively before and after the last chemotherapy of peripheral blood,used flow cytometry technique to detect the proportion of T cell subsets and NK cells in peripheral blood,and compared the change of the part of the quality of life before and after chemotherapy.Results After chemotherapy of total of 66 patients CD3+ T cells,CD3+ CD4+T cells and NK cells of peripheral blood ((68.58± 11.03) ％,(33.53 ± 8.84) ％,(18.27 ± 10.65) ％) significantly lower than before chemotherapy ((74.03±13.04)％,(38.42±9.79)％,(19.83± 10.19)％),the differences were statistically significant(t =4.296,3.387,4.092,P＜ 0.05).Grouping was TAC protocol with AC-T,T cell subsets and NK cells before chemotherapy differences had no statistical significance.But after chemotherapy,CD3+ T cells,CD3+ CD4+T cells,CD3+CD8+ T cells and Karnofky score((64.63±10.01)％,(31.19±7.41)％,(24.66±7.40)％,(68.63± 5.100)％) of peripheral blood on TAC protocol were more decreased than AC-T protocol((72.29± 10.78)％,(35.74± 9.60) ％,(30.15 ± 11.12) ％,(77.29 ± 4.58) ％),the differences were statistically significant (t =2.99,2.15,2.35,2.237,P＜0.05).CD3+ CD4+/CD3+ CD8+ and NK cells were also decreased,but without statistical significance.The body quality of 66 patients was slightly increased after chemotherapy,but without statistical significance.Conclusion The body's immune function and the part of quality of the breast cancer patient's life have declined by chemotherapy drugs in varying degrees.Compared TAC,AC-T protocol has less influence on the immunological function and the part of living quality of patients with breast cancer.
