To study the free cancer cells in the surgical field and prevention of local recurrense of breact cancer with hyperthermic soaking chemocherapy / 临床外科杂志

ABSTRACT

Objective Through the qualitative study of surgical field free cancer cells of patients with breast cancer,to evaluate theprevention effects of intraoperative hot hypotonic solution soaking chemotherapy on cancer recurrence after resection of breast cancer.Methods 94 cases with breast cancer divided in to study group (n=48)and control group (n=46).Before the operation wound closed,both group surgical field washing solutions were collected for examination of free cancer cell,then the wounds of study group were treated with Hyperthermic soaking chemotherapy (41℃～42℃normal saline solutions 3000 ml+5-fluorouracil 1.0 g),once five minutes,total 3～4 times.While the wound of control group were soaked with normal saline solutions only.The soaking solutions were collected for examination of free cancer cell.The rates of free cancer cell in the surgical field and local recurrence rates in the both group were compared.Result The rates of washing solutions and the rates of soaking solution and the localy recurrent rates in the study group were 29.2%,8.3%,6.3%,which in the control group were 26.1%,19.6%,15.2%.Conclusions There are free cancer cells in the surgical field of breast cancer.Hyperthermic soaking chemotherapy can kill free cancer cell and reduce localy recurrent rate.
