64: Managing Indeterminate Thyroid Nodules, with Dr. Kimberly Vanderveen from Denver Center for Endocrine Surgery
Kimberly Vanderveen, MD is a Colorado native and graduate of Bear Creek High School in Lakewood, CO. She received her bachelor’s degree with honors from Muhlenberg College in Allentown, PA. She then earned her medical degree from Northwestern University in Chicago, IL in 2001.
In this episode, the following topics are discussed:
* Two roads of tests: rule out and malignant markers
* Rule-out tests picks up innocent behavior pattern. Most common is Afirma
* Malignant markers, or rule-in tests, are useful at determining extent of surgery, and help avoid a second or third surgery. ThyroSeq, ThyraMIR, Rosetta
* Do patients get both tests? Rule out and behavior?
* Approximately 15% of FNA’s come back indeterminate. Some centers as high as 30%
* Managing indeterminate nodules when a patient chooses no surgery.
* Taking into account emotional, financial, and lifestyle goals of the patient.

Dr. McIver contributes to Moffitt Cancer Center almost 20 years of clinical experience in the care of patients with endocrine diseases, specializing in the evaluation of patients with thyroid nodules and thyroid cancer. He has a particular interest in the management of patients with advanced and aggressive forms of cancer and the role of genetic and molecular techniques to improve the accuracy of diagnosis.

58: No Biopsy is 100% Accurate⎥Molecular Testing Gets Close, with Dr. Bridget Brady from Austin Thyroid Surgeons
Dr. Bridget Brady is Austin’s first fellowship-trained endocrine surgeon.
In this episode the following topics are discussed:
Austin Thyroid Surgeons sees 30 patients per week with thyroid nodules
Up to 80% of US population could have a thyroid nodule(s)
less than 5% of Dr Brady’s thyroid nodule patients test positive for cancer
How relevant is what I don’t know won’t hurt me in thyroid cancer and biopsies of nodules?
BETHESDA system or the middle category, also known as indeterminate
For thyroid nodules that are indeterminate, historically a surgery would be performed
With molecular testing, surgery can be decreased by up to 50%
Afirma molecular testing uses messenger RNA
If Afirma comes back suspicious it does NOT necessarily mean it is cancer
* Imaging has increased thyroid nodule discovery.
* Following patients with small thyroid cancer ? analogous to prostate cancer. Better followed than treated.
* Tiny thyroid cancers can be defined by those nodules less than 1/4 inch in size.
* Less RAI is being used as a part of thyroid cancer treatment. This means, less need to do total thyroidectomy or thyroid lobectomy.
* Dry mouth and dry eyes are risks to doing RAI. Also, there is risk to developing a second malignancy. Most of the secondary cancers are leukemia.
* Risks to operation include changes to voice and calcium levels. Thyroid surgery is a safe operation but not risk free.
* Best question for a patient to ask is, who is my treatment team?
52: Cancer Phobia?⎥Don’t Sacrifice Your Thyroid, with Dr. José A. Hakim – Hospital Universitario Santa Fe de Bogotá
No todos los cánceres de tiroides deben ser operados.
No todos los nódulos tiroideos deben ser biopsiados.
La mitad de la población tiene nódulos tiroideos. El 10% de esos nódulos tienen cáncer. En Colombia, 2,5 millones de personas tienen cáncer de tiroides. 15 millones de personas tienen cáncer de tiroides en los Estados Unidos, y lo más probable es que no lo sepan.
Los estudios muestran que el 30% de los cadáveres tienen nódulos tiroideos con cáncer.
Comprender las repercusiones de hacer una biopsia. Si se trata de un nódulo que no requiere cirugía, incluso si es cáncer, decirle a un paciente esto a veces hace más daño en la forma de estrés emocional que lo que es necesario.
Dr. Shaha specializes in head and neck surgery, with a particular interest in thyroid and parathyroid surgery. He uses an algorithm of selective thyroid tumor criteria (the size, location, stage and type of cancer, along with the patient’s age), to tailor therapy to each individual’s circumstances.
In this interview, topics include:
* The first question a surgeon should ask and why.
* When talking active surveillance or observation, changing the language to deferred intervention, ‘we are going to defer’.
* Understanding the biology of the cancer
* The biology of thyroid cancer is a friendly cancer.
50: Regarding Thyroid Cancer, Are You a Minimalist or a Maximalist? with Dr. Michael Tuttle from Sloan Kettering
Regarding Thyroid Cancer, Are You a Minimalist or a Maximalist?
Often, surgery is not necessary to treat thyroid cancer, but much of the decision will depend on the patient characteristic.
During this interview, Dr. Tuttle discusses the following points:
Challenges of managing thyroid cancer as outlined by the guidelines
Scaling back care for insurance-challenged patients, and adopting a plan that gets the same result without needing the expensive tests
Desired outcome is survival and no recurrence, a third is for no harm that would be caused by an unnecessary surgery
Unwanted side affects of thyroid cancer include nerve damage, parathyroid damage, and infections
48: Innovaciones en el Tratamiento del Cáncer de Tiroides, con el Dr. Hernán Tala desde Santiago, Chile
Dr. Hernán Tala es endocrinólogo de la Clinica Alemana en Santiago, Chile. Su area especialidad incluye cáncer de tiroides avanzado, endocrinologia general, y enfermedades tiroides.
Los temas presentados incluyen:
* Una mejor comprensión de la biología del cáncer de tiroides, y que no todo el cáncer de tiroides es igual. La enfermedad es única en cada paciente.
* La importancia de entender el perfil del cáncer en cada paciente.
* Diagnóstico del nódulo.
* Perfil molecular del nódulo tiroideo.
* Una pausa en la exploración universal del cáncer de tiroides.
* Vigilancia activa
47: Treatment of Thyroid Cancer in Japan, with Dr. Takahiro Okamoto from Tokyo Women’s Medical University
A different approach to treating thyroid cancer compared to the U.S.
Dr. Takahiro Okamoto helped write the Japanese guidelines on thyroid cancer. He is Professor & Chair of the Department of Surgery at Tokyo Women’s Medical University.
Key points from this episode include:
* Most Western countries carry out total thyroidectomies, whereas in Japan, the approach is more conservative with a fundamental practice of hemithyroidectomy whenever possible.
* By not doing a total thyroidectomy, this allows the patient to not avoid taking thyroid replacement medication.
* Complete thyroidectomy is conducted when 80-90% of lymph nodes have metastasis.
* I-131 treatment is decreasing despite cases of cancer increasing
* For I-131 treatment, patients wait more than 6 months post surgery.
* When receving I-131 treatment, patients be admitted to hospital for several days.
* TSH suppression therapy is common in Western countries, whereas in Japan, measures are taken to avoid TSH suppression by not removing all of the thyroid.
* Normal TSH in Japan is 4.3 or less.
Dr. Özer Makay is an expert in nerve monitoring during thyroid surgery, and has been a guest faculty member in South Korea, Italy, France, the Netherlands, Germany, Belgium and Bulgaria.
This episode covers the following topics:
* Protecting the recurrent laryngeal nerve (RLN) and superior laryngeal nerve during thyroid surgery.
* Outcomes of damaging these nerves during surgery include no voice, hoarseness, shortness of breath, problem with drinking water or aspiration, impaired physical exertion with something as simple as climbing a flight of stairs.
* Why some centers have a higher occurrence of damage during thyroid surgery and include an error rate as high as 10%
* The cause of the damaged nerve include stretching or traction, and cutting or stitching.
* How to reduce risk.
* Is it possible to reattach a cut nerve?
