In vitro growth peculiarities of some human ovarian tumours

The possibility of applying a short duration method of in vitro cultures for detecting malignancy of ovarian tumours with borderline lesions and with incipient malignant ones was investigated in 24 ovarian tumours. Three main types of histocultures were described in relation with the in vitro behaviour of ovarian tumours and their cytomorphology (atypic growth, mixed growth and normal one). The category of mixed type growth cultures is discussed, corresponding to ovarian tumours with histopathological borderline lesions, with incipient malignancy, as well as two cilio-epithelial cystadenomae rendered malignant with peritoneal seedings.
