My endo is saying and the radiologist wrote on my last and recent Ultrasound report that none of nodules meet the criteria for biopsy and that I don't have calificication and that blood flow is normal. But I know that quite a few people who have had thyroid cancer had no suspicious worrisome Ultrasound features but they still had small thyroid cancer anyway! And Dr.Susan Mandel who is a top thyroid cancer specialist at the University of Pennsylvania Hospital and who works with my endo,has written many articles in medical journals that are online including The Journal of Endocrinology and Metabolism. She was part of a major conference panel of many endocrinologists and radiologists who met in Washington in October 2004 to discuss the Ultrasound features of cancerous and benign nodules and the diagnoses and treatments of thyroid cancer. The conference is online on the web site for the Radiology Society Of North America and it's called, Management of Thyroid Nodules Detected at US:Society of Radiologists in Ultrasound Consensus Confernce Statement.
They say that solid or predominantly solid nodules have a higher risk of malignancy than do mixed or predominantly cystic nodules.Cystic and almost cystic nodules have a very low likelihood of being malignant.Nodules with mixed composition have an average risk of malignancy.For this reason,the recommended minimal size for US-guided FNA is lower for solid or predominantly solid nodules than the recommended minimal size for mixed and cystic nodules.Yet they are telling me none of my nodules meets the criteria for biopsy when one is described as solid,not even mostly solid,but solid!!!!
They also say,that several Ultrasound features have been found to be associated with an increased risk of thyroid cancer including,presense of califications,hypoechogenicity,irregular margins,absence of a halo,predominantly solid composition,and intranodule vascularity.However,the sensitivities,specificities,and negative and positive predictive values for these criteria are extremely variable from study to study,and no US feature has both a high sensitivity and a high positive predictive value for thyroid cancer.The feature with the highest sensitivity,in the range of 69.)%-75.0% is solid composition;however this feature has a fairly low positive predictive value in that a solid nodule has only a 15.6-27.0 % chance of being malignant.
Thank you both for your replies.
I really don't know what to do or what other doctor to turn to and I am very worried and really need peace of mind! I had asked on here before should I have a thyroid scan to see if any of my nodules are cold? Maybe the combination of cold nodules and round shaped nodules,no halos around them,one solid and one hypoechoic, if will steer me more towards surgery.The only problem is that 85-90% of cold nodules are also benign.
Dr.Mark Lupo told me on here in December 2006 and I see he has also told others on here,that with a normal TSH there is no point in getting a thyroid scan but I see many posters on here did get scans to see if their nodules were cold even though they had a normal TSH and other thyroid blood tests. pep88 utahmomma said that PET scans don't really show thyroid cancer because it's not usually an aggressive type and grows slowly.But a representative at The National Cancer Institute suggested that I get a PET scan and she said that they have information which she is going to mail me,that uses PET scans to dectect thyroid cancer because the cancerous areas light up.pep88 please read through all of my other information I wrote on here when you get a chance,thanks.
You gave SO much information. But in scanning through the thread at what you've written (I can't read it all, I have to go to bed, it's late...), I see no mention of any diagnostics other than an Ultra Sound and blood tests. If you are concerned, and you seem to be convinced there is something to these nodules, seek out a pet/ct/mri or a new doc who will concent to such or further diagnostics.
There is a weird little intutition button that each of us has regarding our health. I followed mine when I accidently found a nodule (1.2cm) on a ct scan for an unrelated issue. *I* brought it up to my doc (after having a copy of the CT scan report faxed to me, she wasn't even looking at "that" part of the scan results). And it was *I* who insisted we take a closer look at it. It was small (the one...), but there were two, and I could see she was waffling. She almost advised that I wait and see, I could see the words forming to come out, part of it did, but I just knew we found it for a reason. There was also some calcification that showed up on the scan and that seemed to seal the deal.
I had FNA about 2 weeks later, and then was referred to a surgeon. For the record, it was cancer. Papillary with follicular variant.
Somehow I knew. I just knew. Something was pressing "that button". If that is how you're feeling, make someone listen. We can pontificate for days/months... make this thread the longest in history...(and although this one is getting there, we'd have a hard time beating the "pub" thread from friday night...), but in the end, if you have "that" feeling... Make it happen!
I wish you well, good luck with your journey.
An ultrasound once a year should be fine, but I am not sure. Others may have more info. on that.I don't know the features of the nodules except they were large, I never thought to ask>
Thank you for your reply,
No I meant how long it should be to tell if the nodules haven't grown or changed from an ultrasound that had been done 9 months before this one. It's actually a year and half since my nodules were discovered by accident and they are still really small with the largest at 9mm.
Do you know whatany of your Ultrasound features of your cancerous nodules were?
I was diagnosed 2 years ago when I was 46. I had 5 growths. The largest was 4.8cm. and the rest were between 1.5 and 3cm. They were discovered because I felt like I had food in my throat so asked my doctor to look when I was in for an annual check up. She saw nothing in my throat and started feeling it. She sent me for an xray, and when that showed something she sent me for a CTscan for a better picture. That came with the news of some nodules so she sent me to a endocrinologist(my first visit with one) who said multi nodules are rarely cancerous but lets biopsy them anyway. He said he would send me to a surgeon for a thyroidecotomy regardless of the biopsy, because they were so large. He was surprised the results came back with a diagnosis of cancer. I was not seen locally because of the need for a large neck disection, and went to a hospital 2 hours away. When you have your TSH checked have they also done a thyroglobulin test? I'm not sure what is the recommended time to check blood work when being watched, but I would guess maybe every 6 months.
