CA 125 at 1500+ Possibilities Other than Recurrence of Ovarian Cancer

Hello Dr.-My wife age 65[looks and feels much younger]was diagnosed with stage 3A ovarian cancer 5 yrs ago. After 8 treatments of carboplatinum and taxol, she's been in remission for almost 5 yrs. In April 2010 her CA 125 jumped from 16 to 52. On July 15,2010 it jumped to 752. As a follow up to Ca 125  being at 752, her oncologist ordered a CAT scan of pelvis and abdomen -totally normal, no evidence of disease. Just retested Ca 125 July 28 on visit to oncologist. It was in the 1500's. Her Dr. does not want to treat since she is asymtomatic and is requesting a new CAT and Ca 125 in the beginning of October. Earlier this year she tested positive for Sjogren's Disease. Also, has osteoarthritis of hands which has caused a mild deformity of the hands.  . At first the rheumatologist though it might be Lupus or rheumatoid arthritis. Further testing just came up only with Sjogren's Disease and the arthritis of hands. Two years ago she was diagnosed with Celiac disease and maintains gluten free diet. Can mild connective tissue disease such as Sjogren's and arthritis of the hands or Celiac disease cause these elevations?  What could be going on other than ovarian cancer? What would you recommend?

Thank you

Hi There
thank you all for your wonderful comments.I agree and resonate with everything you are saying.

First to address sklucky:
Sjorgren's syndrome and intestinal disorders can cause elevated CA 125 protein secretion. The levels in the thousands without radiologic signs of cancer does make me wonder whether there is another reason for the excess protein levels in the blood.

It may be that a laparoscopy to look will be the only way to quickly answer the question, has the cancer come back.

Now the dilemma of a rising CA 125 level in a woman with known ovarian cancer who is asymptomatic and has a normal scan:

there was an abstract at the 2008 International Gyn Cancer society meeting in Bangkok that reported  on women with ovarian cancer after primary treatment. They followed women either by clinical exam alone or by CA 125 levels. Treatment for recurrence was started based on CA 125 or exam / xray findings in the respective groups. There was no difference in survival

Interestingly, I just did a quick pubmed search. I may have missed it but I do not see that this data has been published yet now 2 years after presentation. (I am always a bit suspicious of data that does not get published ).

This abstract caused quite a stir and many oncologists got on the bandwagon of stopping CA 125 checks and being - well- a bit more nihilistic about intervention for recurrent ovarian cancer.

I agree with Pat 4444. That intuitively does not make sense. But there is no good data either way.

What I would say is now known and more and more information is coming on this - is that what we call ovarian cancer is not just one disease. Even for those cancers that look the same under the microscope (example: grade 3 serous papillary adenocarcinoma), there are porbbaly many different diseases based on molecular profile.

This new understanding ,of course, correlates with what we have known clinically for decades: that there is a wide range of behavior to cancers that grossly and microscopically look the same. Some women have recurrences within months of finishing chemo.others go ten years.Some have recurrences only in one spot, others have recurrences everywhere.and so on.  

So with such a diverse disease, I find it hard to make a blanket statement about how we should follow women with a history of cancer and how we should treat  recurrences.  How I am going to mange my lovely patients in their 80s with a recurrence is totally different than my patients less than 80.  Or someone with no health problems who could tolerate chemo versus someone in renal failure.

So I would continue to check CA 125 levels in patients where it makes sense to aggressively treat and treat early for a recurrence.

I am waiting for the doctor to reply to your question, I cant seem to get on here quick enough to post something since there is a limit to how many posts can be put up her daily.  My mom also recently had a rise in her CA level from 13 to 305 and the CT showed nothing.  I am assuming there is cancer there but not large enough to show up on a CT since these scans only seem to pick up 1cm tumors or larger.  Its scary...she is going to see her oncologist next Friday - hope to get answers.  We were told her would probably do one of 3 things, chemo, surgery or just wait - im not agreeing at all with waiting.  Obviously with the rise in CA after being normal since Nov 09 - something is going on.

Good luck and I hope you get answers soon - the waiting is frustrating and scary

Recent studies have shown no improvement in mortality by treating rising CA 125 without other evidence such as symptoms or CAT scan findings. My wife's oncologist, who is top notch, has asked my wife to get another CAT in 2 mos. She also feels exploratory surgey at this point without evidence of cancer would be  like trying to find find a needle in a haystack. She feels the CA 125 can be too anxiety provoking and doesn't want to retest until CAT scan. Bottom line -no chemo or surgery at this point- watchful waiting.

Thanx for your input.

Yes, nerve wrecking waiting - moms galbladder test showed the flow was normal except in one part which is kinda worrisome.  More to come when she see's the onocologist at Rush on Friday.  I have heard about Doctors that do not want to treat rising CA levels until there is actual proof there is cancer on the CT - but in my eyes, that is just waiting and giving this stuff time to grow anywhere in the meantime.  Upsetting to me..... -

You both are in my prayers.  Keep me posted, I check this site often

Would love to hear your mom's Dr's take on significantly increasing CA 125 without symptoms or evidence on CAT scan. My wife's Dr. says to wait for evidence before treatment.

My prayers are with your mom.

Keep us posted. I am leary of basing a decision about restarting treatment based on ONE STUDY. My daugter and son in law are epidemiologists/statiticians and say one study is not sufficient to make a decision not to treat rising ca 125's while the bulk of tumor is low. THey reviewed that study for me and it confirmed their opinion. They were surprised Docs were changing recommendations based on that.

What we need is a replication of that study with controls for subsequent treatment. THere were none in the original study. THe problem with a study with big numbers of people is that everything is significant.

So I am going with my intuition which is that the earlier treatment starts the better. Zap the cells before they start making masses.
