Quality of Life in Metastatic Breast Cancer (MBC) Patients in Second Line Monochemotherapy

Study of Quality of Life in Patients With Metastatic Breast Cancer Treated With Second-line Monochemotherapy

Post-authorization, prospective follow-up, multi-centre, national study to estimate definitive deterioration in the quality of life in patients with metastatic breast cancer treated with second-line monochemotherapy.

Post-authorization, prospective, multi-centre study in Metastatic Breast Cancer patients treated with second-line monochemotherapy.

A total of 200 patients are expected to be recruited from 32 Spanish sites.

In this study the results perceived by patients will be compiled to assess overall Quality of Life (QoL) in MBC patients treated with second-line monochemotherapy, using the EORTC QLQ-C30 questionnaire (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire) and its modules EORTC QLQ-BR23 (EORTC Breast Cancer specific) and EORTC QLQ-CIPN20 (EORTC Chemotherapy-Induced Peripheral Neuropathy).

Patients will be evaluated at the time of acceptance to participate in the study after signing the informed consent and will be tracked every three months during treatment with second-line monochemotherapy, coinciding with routine assessments within normal clinical practice. When the patient completes treatment with second-line chemotherapy he/she will enter the post-treatment period, with follow-up at six and 12 months after completion of treatment. Also, patients will be followed to assess survival until the end of the study (30 months after enrolment of the last patient in the study). Follow-up time has been established based on the median survival of patients with MBC
