COSA:Early detection of cancer in AYAs/Individual cancers/Thyroid cancer
|Guidelines contents||Introduction||Recommendations||Communication||Referral||Symptoms and signs||Clinical assessment||Cancers||Resources|
|AYAs presenting with symptoms of tracheal compression including stridor due to thyroid swelling require immediate emergency department admission.||D|
| AYAs presenting with a thyroid swelling and one or more of the following should be urgently referred to a specialist:
|AYAs presenting with a thyroid swelling without stridor or any of the features indicated above should be referred by GPs for thyroid function tests. Patients with hyper- or hypothyroidism and an associated goitre are very unlikely to have thyroid cancer and could be referred to an endocrinologist. Those with goitre and normal thyroid function tests should be referred to an endocrinologist.||D|
|In AYAs presenting with symptoms and/or signs suggestive of thyroid cancer, a referral for an ultrasound investigation may be made, but this should not delay referral to a specialist. Referral for isotope scanning is likely to result in unnecessary delay and is not recommended.||D|
Symptoms and signs
Thyroid cancer often causes no symptoms. The most common sign is a hard, irregular mass in the neck near the Adam’s apple; cervical lymphadenopathy may be present. Symptoms may include hoarseness or voice changes, cough or difficulty in swallowing.
Patients with symptoms of tracheal compression including stridor due to thyroid swelling require immediate emergency department admission.
Adolescents and young adults (AYAs) presenting with thyroid swelling along with symptoms and/or signs of cancer, history of neck irradiation or family history of an endocrine tumour should be urgently referred to a specialist.
AYAs presenting with a thyroid swelling without stridor or any of the features indicated above should be referred by general practitioners (GPs) for thyroid function tests (TSH, T3, Free T4).
Other investigations such as ultrasound may be valuable for assessing patients with thyroid cancer, but this should not delay referral to a specialist. Referral for isotope scanning is likely to result in unnecessary delay and is not recommended. FNAC may be a useful preoperative diagnostic tool for thyroid cancer, but the patient should be referred to a specialist first.
Patients with hyper- or hypothyroidism and an associated goitre are very unlikely to have thyroid cancer and could be referred to an endocrinologist. Those with goitre and normal thyroid function tests should be referred to an endocrinologist.
Exposure to ionising radiation is an important risk factor for thyroid cancer; this may be through treatment therapies for conditions such as cancer, acne, tinea or enlarged thymus or environmental sources such as radiation fallout. Thyroid cancer has also been linked to genetic disorders like familial adenomatous polyposis (FAP) and benign thyroid disease.
However, thyroid cancer can occur in AYAs without any of these risk factors.
