Serous borderline tumor of the ovary

[@niallicious]

Another great video, ovarian borderline tumors can be difficult the use of virtual slides really helps bring the concepts together

Glad it was helpful!

I was told I had cancer turned out I had this borderline tumor I’m wondering was it hard to diagnose based on the mri should I have had a second opinion - they wanted me to get a hysterectomy(they told me I had for sure ovarian cancer with no biopsy) I’m glad I didn’t get one

'Thanks for your great lecture. I have a question. I'm very confused about : "non-invasive" implant and "invasive" implant in serous tumor of ovary. How can I distinguish between these terms and true invasion? Thank you.

[@LewisHassell-OPEN]

These terms are confusing and are largely being abandoned. Desmoplastic stroma does not distinguish the two, so it really depends on seeing deep invasion into the tissue of an organ- the bowel, bladder, etc. Useful references: www.ncbi.nlm.nih.gov/pmc/articles/PMC5423818/ and www.pathologyjournal.rcpa.edu.au/article/S0031-3025(17)30676-1/pdf

Thank you Dr

What are the likelihood that the other tumor on my other ovary is also borderline ? Vs cancer - they didn’t biopsy it

[@LewisHassell-OPEN]

It is important to stage borderline tumors. Foci of invasive (low grade serous carcinoma) can be present in the peritoneum or other sites co-existant with a borderline tumor in the ovary. That said, if you already had surgery, there may be reasons to follow clinically rather than going back to stage, but it would depend on factors like risk of surgery, age, size of the tumor(s) and family history. It's not common to find areas of invasion, but it is something we see from time to time (say once a year in a large center.)
