DYNAMIC OBSERVATION OF PERIPHERAL T CELL SUBGROUP IN PATIENTS WITH RECTAL CANCER PREOPERATIVELY AND POSTOPERATIVELY / 中国医师进修杂志

ABSTRACT

Objective The changes of peripheral T cell subgroup in patients with rectal cancer preoperatively and postoperatively were studied dynamicly.Method Peripheral T cell subgroup of 46 patients with rectal cancer was measured dynamicly by the monoclonar antibody enzyme labelling techniques during the preoperative and postoperative period.Result (1)CD3 cell and CD4 cell decreased markedly,the CD4/CD8 rate increased apparently in patients with rectal cancer.(2)Depressed immunity was related to the term of cancer.(3)The immunity of patients treated by radical rectal resection may recover gradually,the immunity of patients treated by palliative rectal resection,colostomy and laparotomy was depressed constantly.Conclusion The depressed immunity of patient with rectal cancer was related to the tumour preponderance.T cell subgroup dynamic surveillance was important to juide the possibility of recurrence and prognosis in patient with rectal cancer.
