Dynamic changes and correlation between symptoms and quality of life in patients with breast cancer during...

Standardized chemotherapy for breast cancer can improve the survival of patients, but during the process, it is accompanied by a variety of symptoms.

To explore the dynamic changes of symptoms and quality of life in breast cancer patients at different time points during chemotherapy, and to explore the correlation with quality of life.

A prospective study method was used to collect 120 breast cancer patients undergoing chemotherapy as the research objects. The general information questionnaire, the Chinese version of the M.D. Anderson Symptom inventory (MDASI-C), and the European Organization for Cancer Research and Treatment (EORTC) Quality of Life questionnaire were used in the first week (T1), first month (T2), three month (T3) and 6 months after chemotherapy (T4) to conduct dynamic investigation.

The symptoms of breast cancer patients at four time points during chemotherapy period were: psychological symptoms, pain-related symptoms, perimenopausal symptoms, impaired self-image, and neurological related symptoms etc. At T1, it exhibited 2 symptoms, however as moving along the chemotherapy process, the symptoms are increasing. The severity is (F= 76.32, P< 0.001), life of quality (F= 117.64, P< 0.001) vary. At T3, there were 5 symptoms, and at T4 symptom number increased to 6 with worsening quality of life. It exhibited positive correlation with scores in multiple domains of quality of life (P< 0.05), and the above symptoms showed positive correlation with multiple domains of QLQ-C30 (P< 0.05).

After T1-T3 of chemotherapy in breast cancer patients, the symptoms become more serious and the quality of life reduced. Therefore, medical staff should pay attention to the occurrence and development of patient's symptoms, create a reasonable plan from the perspective of symptom management and carry out personalized interventions to improve patient's quality of life.
