PTC is a rare cancer and usually develops in pre-existing thyroid nodules, which are not common in children. PTC is often multifocal and bilateral. Low-risk subtypes such as classic PTC and follicular variant account for the majority of PTC, while high-risk histologic subtypes such as tall cell variant, diffuse sclerosing variant and poorly differentiated thyroid cancer occur more rarely in children. It is worth noting that the size of the thyroid in children is smaller compared to that of adults. Therefore, the size criteria used for tumor staging as well as the diagnosis of papillary microcarcinoma in adults, do not apply to children. Family history of thyroid cancer, exposure to external radiation, iodine deficiency, and autoimmune thyroid diseases as well as some genetic syndromes increase the risk of its occurrence.</p>","PeriodicalId":12871,"journal":{"name":"Hellenic journal of nuclear medicine","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10129169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there is clear benefit from adjuvant systemic treatment for patients with early-stage triple negative and HER2 positive breast cancer, it was unclear in the past which patient with luminal breast cancer needs adjuvant chemotherapy. As a result, we used to overtreat or undertreat patients. In the era of personalized treatment, genomic panels have become as or more important than the anatomic extent of disease to define prognosis in luminal breast cancer. Several gene expression assays are available for consideration of adjuvant systemic therapy categorizing patients according to genomic risk for recurrence (e.g., Oncotype, Mammaprint, etc). Except for the high and low risk signature, more recently Mammaprint announced that patients with ultra-low risk signature have excellent prognosis, distinctive from low risk with 8-year BCSS above 99%, regardless of age, clinical risk or treatment received.
