ObjectiveTo compare the differences in patient satisfaction and health-related quality of life after total mastectomy and breast-conserving surgery for breast cancer. MethodsBreast cancer patients who underwent surgical treatment in the First Hospital of Shanxi Medical University and The People’s Hospital of Shanxi Province from March to June 2021 were selected as the research objects by convenient sampling method. Self-designed questionnaires were used to evaluate the general situation of the patients. Patients’ satisfaction and quality of life were investigated by using the postoperative scale of the BREAST-Q module of total mastectomy (to investigate patients after total mastectomy) and the postoperative scale of the breast-conserving plastic surgery module (to investigate patients after breast-conserving surgery), and the patient-reported outcomes of total mastectomy and breast-conserving surgery were compared, including breast satisfaction, psychosocial health, chest and upper limb physical health, sexual health, medical team satisfaction, and information satisfaction. ResultsIn this study, there were 100 patients in the total mastectomy group and 50 patients in the breast conserving group. There were no significant differences between the two groups in marital status, monthly family income, education, body mass index, whether combined with other physical diseases, chemotherapy, targeted therapy, axillary lymph node dissection, tumor stage, and molecular typing (P>0.05). The rates of radiotherapy and endocrine therapy in the breast conserving group were higher than those in total mastectomy group ( χ2=48.701, P<0.001; χ2=15.891, P<0.001). The scores of quality of life and patient satisfaction scores of the breast conserving group including breast satisfaction, satisfactions of breast doctors, nurses and other doctors, social and mental health, sexual health score were higher than those of the total mastectomy group (P<0.001), but there was no significant difference in the physical health of chest and upper limbs score between the two groups (P>0.05). In addition, the satisfaction score of radiotherapy information in the breast conserving group was 69.40±20.44 and that of medical information given by breast surgeons was 87.04±19.46. ConclusionScores of breast satisfaction, psychosocial health, sexual health, and health-related quality of life in breast-conserving patients are higher than those in total mastectomy patients.
