Time course of changes in 6-sulfatoxymelatonin excretion in patients with breast cancer after various neoadjuvant chemotherapy options

Abstract

The level of the metabolite 6-sulfatoxymelatonin (6-SOM) was studied on automedia before and after neoadjuvant systemic polyche- motherapy and neoadjuvant chemotherapy. Specific therapy was not found to result in normalization of 6-SOM levels, which may be regarded as a poor endogenous factor.
