Survey of quality of life for patients with breast ductal carcinoma in situ and analysis of related factors

Abstract

Objective To study the quality of life (QOL) of patients with ductal carcinoma in situ (DCIS) and to analyze the relevant factors affecting their QOL.Methods A total of 84 patients with DCIS and 125 patients with invasive breast cancer were surveyed.Researchers used SF-36 to assess the QOL of participants at one year after operation.The relationships between some information of patients and SF-36 score were analyzed,such as age,the type of surgery,endocrine therapy,education,marital status,working status and health insurance.Results Compared to normal women,patients with DCIS had lower QOL in physical function (t =2.468,P =0.029),bodily pain (t =2.076,P =0.039),general health (t =2.153,P =0.033) and mental health (t =3.396,P =0.003).Patients with invasive breast cancer also had poorer QOL in physical function (t =5.638,P =0.002),bodily pain (t =5.417,P =0.002),vitality (t =4.438,P =0.002),general health (t =3.960,P =0.002) and mental health (t =6.020,P =0.001).QOL of DCIS patients was similar to that of invasive breast cancer patients,except that scores of physical function (t =2.714,P =0.032) and vitality (t =2.134,P =0.040) were better in DCIS patients.Endocrine therapy significantly affected the score of QOL of DCIS patients.DCIS patients with endocrine therapy had poorer score in physical function (t =2.082,P ＜ 0.05),bodily pain (t =2.003,P ＜ 0.05),general health (t =2.751,P ＜0.05),vitality (t =2.048,P ＜ 0.05) and mental health (t =4.162,P ＜ 0.05).Conclusion Patients with DCIS have poor QOL at one year after operation.Endocrine therapy significantly reduces their QOL.
