ssp2006: SSP2006 classifier for identification of breast cancer molecular subtypes (Hu et al 2006)

Description

List of parameters defining the SSP2006 classifier for identification of breast cancer molecular subtypes (Hu et al 2006).

Usage

Details

Three versions of the model are provided, each of ones differs by the gene expressions standardization method since it has an important impact on the subtype classification: [object Object],[object Object],[object Object] The model ssp2006.robust has been shown to reach the best concordance with the traditional clinical parameters (ER IHC, HER2 IHC/FISH and histological grade). However the use of this model is recommended only when the dataset is representative of a global population of breast cancer patients (no sampling bias, the 5 subtypes should be present).
