Metastatic Breast Cancer
Conditions
Brief summary
Despite treatment improvements in breast cancer, a large number of patients still progress to the metastatic stage. Metastatic breast cancer patients have an extremely unfavorable prognosis. Not only efficacy, but also quality of life are in the focus when planning a therapy or therapy sequence for metastatic breast cancer patients. Therapy options include anti-hormonal Therapy, antibody therapies, other targeted therapies and chemotherapies. One of the most effective chemotherapies in the adjuadjuvant and metastatic setting is paclitaxel. However drug handling and its side effects can compromise patients quality of life and can have an impact on the pharmacokinetics of the drug. In metastatic breast cancer patients increasing therapy efficacy and reduction of side effect frequency are considered to be advancements of therapy. One of these advancements is the development of a cremophor free and albumin bound paclitaxel, nab-Paclitaxel (Abraxane), which is thought to have a better efficacy and reduced toxicity profile. Nab-Paclitaxel is approved for the treatment of metastatic breast cancer after a failure of first-line therapy and when antracyclines are not indicated. The SERAPHINA study aims to investigate in the use of nab-Paclitaxel in daily routine and the frequency and perception of side effects. As a non-interventional study, the SERAPHINA Study will assess the patient characteristics and describe the patient cohort, in which nab-Paclitaxel is given. This includes age distribution and characteristics documented by the patients themselves.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Epidemiological assessment of progression free survival (PFS) under real life conditions. | A patient remains in the study for a maximum of 36 months or until death, whatever occurs first | PFS defined as the time to the first progression or death after therapy start of nab-Paclitaxel. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of other prognostic characteristics | A patient remains in the study for a maximum of 36 months or until death, whatever occurs first | OS (overall survival) is defined as the time to death from therapy start of nab-Paclitaxel. Reason for death is taken into consideration as well (BBCS, breast cancer specific survival). |
| Influence of age on the prognosis and quality of life. | A patient remains in the study for a maximum of 36 months or until death, whatever occurs first | Progression free survival, overall survival and quality of life assessed with PRO |
| Incidence of adverse events, serious adverse events will be reported. | A patient remains in the study for a maximum of 36 months or until death, whatever occurs first | NCI Common Toxicity Criteria Version 4.03 |
| Quality of life (FACT-B -Taxane, Version 4, nab-Paclitaxel specific questions, NCCN-Distress-Thermometer) | A patient remains in the study for a maximum of 36 months or until death, whatever occurs first | Patient reported (PRO) quality of life is assessed with standardized questionnaires (FACT-B, Version 4, FACT-Taxane, Version 4, nab-Paclitaxel specific questions, NCCN-Distress-Thermometer. |
| Influence of breast cancerpatient characteristics on prognosis, adverse event frequencies, quality of life and therapy decision making. | A patient remains in the study for a maximum of 36 months or until death, whatever occurs first | The patient group is described by patient and tumor characteristics and a series of questionnaires assessing health and socioeconomic status and geriatric assessment status. These parameters that describe the patient cohort will be analyzed with regard to their influence on prognosis, adverse event frequencies, quality of life and therapy decision making. |
