ABSTRACT
OBJECTIVES:
To evaluate delay to access to adjuvant radiotherapy for women with breast cancer and to study impact on prognosis.METHODS:
A restrospective descriptive study in the teaching hospital of Tours between 1st January 2007 and 31th December 2013. All women managed for an invasive breast cancer during this period were included with exclusion of women with indication of chemotherapy (neoadjuvant/adjuvant). Delay between surgery and radiotherapy were recorded. Overall survival and recurrence free survival were used to evaluate the impact of delays on prognosis.RESULTS:
Of the 1855 women with an invasive breast cancer, 904 (48.7%) had an adjuvant radiotherapy without chemotherapy. In the whole population, a delay surgery-radiotherapy>90 days was found as an independent factor negatively impacting recurrence free survival (HR=2.12 [1.03-4.36] p=0.04). In the group of patient with a breast conservative surgery, a delay surgery-radiotherapy>65 days was found as an independent factor negatively impacting recurrence free survival with HR=2.29 [1.16-4.54], p=0.02. A delay surgery-radiotherapy>70 days was found as an independent factor negatively impacting Overall survival and HR=3.41 [1.005-11.62], p=0.04.CONCLUSION:
Delay to access to adjuvant radiotherapy is an independent factor impacting patient's survival, especially in the case of breast conservative therapy.Palavras-chave
