Breast Cancer Patients, Therapy Related Tumor
Conditions
Brief summary
There is currently no strict recommendations for the management of patients who have received at least one or two lines of anthracyclines-based chemotherapy and taxane therapy for advanced breast cancer. However, Halaven® can represent a therapeutic alternative at this stage of the disease. Indeed, since march 2011, Halaven® has been granted Marketing Authorization (MA) for patients with metastatic or locally advanced breast cancer, whose disease has progressed after at least two lines of chemotherapy for advanced disease (3rd line). In these patients, the indication for marketing authorization specifies that the previous treatment must have included an anthracycline and a taxane except in patients who can not receive these treatments. An extension of indication was obtained on 27/06/2014 with a marketing authorization obtained in the treatment of locally advanced or second-line metastatic breast cancer. According to the Transparency Commission of the High Authority of Health (HAS dated September 23, 2015), Halaven® (Eribulin), administered as monotherapy, in the third line of treatment and beyond, represents a therapeutic option, because it brings an improvement of medical service rendered compared to Capecitabine (XELODA®) and Vinorelbine (NAVELBINE®). In addition, Halaven® (Eribuline) administrated as monotherapy in second-line of treatment is an alternative to other monotherapies recommended for the treatment of locally advanced or metastatic relapsed breast cancer, such as Capecitabine (XELODA®). and Vinorelbine (NAVELBINE®). But, no improvement of medical service rendered has been reported in second line of treatment. According to these results, it would be interesting to have additional data concerning the use of Halaven® (Eribulin), in the second and third lines, but also in the fourth line. For this purpose, the investigators propose to perform a study in patients with metastatic breast cancer who have failed treatment after the first line and beyond. In this study, the investigators will be particularly interested in long-responder patients, that is to say, in objective response or with stability for 6 months or more under Halaven®, in order to better characterize these patients. Patients must have been treated by Halaven between September 2011 and December 2016, to have a sufficient follow-up for the survival data of the patients.
Detailed description
The investigators will perform a cross-sectional study in patients with metastatic breast cancer who have failed treatment after the first line and beyond. In this study, the investigators will be particularly interested in long-responder patients, that is to say, in objective response or with stability for 6 months or more under Halaven®, in order to better characterize these patients. Patients must have been treated by Halaven between September 2011 (the year of obtaining the MA in the 3rd line of treatment) and December 2016, to have a sufficient follow-up for the survival data of the patients. The investigators will also focus on patients with liver metastases because there is limited data in this population.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Measure Scarff Bloom Richardson grade tumours of patients who received Halaven® and who were in response since 6 months or more | up to at least 6 months after Halaven® start | -pathology of primitive cancer : Scarff Bloom Richardson grade The Scarff Bloom Richardson garde will be measured with a scale from I to III. A grade III represent a worse outcome. |

| Characterize metastatic localizations of patients who received Halaven® and who were in response since 6 months or more | up to at least 6 months after Halaven® start | number of patients with metastatic localizations |
| Characterize patients who received Halaven® and who were in response since 6 months or more | up to at least 6 months after Halaven® start | number of patients with liver metastasis, surgery of liver metastasis |
| Measure the number of Halaven® injections to obtaine the best response in patients who received Halaven® and who were in response since 6 months or more | up to at least 6 months after Halaven® start | -number of Halaven® injections until the best response is obtained |
| Measure the best response under Halaven® in patients who received Halaven® and who were in response since 6 months or more | up to at least 6 months after Halaven® start | -duration of the best response under Halaven® (in months) |
