  2. Prognostic impact of histology, tumor stage, Myasthenia Gravis, sex, number of immature and mature vessels, and total number of tumor vessels on freedom-from-recurrence and cause-specific survival are shown. The following cut-off values were used for dichotomizing patients into high and low subgroups: Immature Vessels: 71.3; Mature Vessels: 14.3; Total Number of Vessels: 91.3; Activin A: 483.3 pg/mL; Follistatin: 776.5 pg/mL. *Univariable cox-regression analyses of Activin A and Follistatin serum levels for predicting cause specific survival were not possible due to lack of events.
