All parameters were evaluated for the whole group of non\u2010gynecological tumors as well as separately for each specific tumor type.

This pattern is dependent on the primary origin of the tumor. Doppler parameters, however, cannot differentiate between primary ovarian cancer and metastatic non\u2010gynecological tumors.
