Study of fallopian tubes reveals evidence of 'precursor escape' — a novel concept in high-grade serous carcinoma
from Medical Xpress
More than two-thirds of women with ovarian cancer have high-grade serous carcinoma. Up to 90 percent of HGSCs are not detected until they are beyond the ovaries or fallopian tubes, at which point it may not be possible to fully remove the tumor. Many of these cancers are now known to originate in the fallopian tube, which is the site where almost all early HGSCs are discovered in healthy women undergoing resection of fallopian tubes. In contrast, among women who first come into the clinic with symptoms of advanced HGSC that has already spread beyond the gynecological region, clinicians can often find little or no evidence of malignancy in the fallopian tubes.
