Official title
Bisphenol and Phthalate Exposures in Women With Triple Negative Breast Cancer Receiving Doxorubicin Chemotherapy - a Pilot Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In this observational pilot study urine samples will be collected from women receiving neoadjuvant chemotherapy with doxorubicin for triple negative breast cancer to determine whether: 1) exposures bisphenol and phthalate levels change over the course of neoadjuvant chemotherapy, and 2) levels differ between black women and those of other racial groups. The hypothesis is that bisphenol and phthalate levels will be similar to those of the general US female population at the time of diagnosis, however levels will increase during treatment due to exposure to plastics in the medical setting. The investigators also hypothesize that because of differences in personal care product use, black women may have higher urinary levels of bisphenols and phthalates prior to starting chemotherapy.
