Introduction: A epidemic increase in the incidence of papillary thyroid carcinoma (PTC) has been happening within the last 25 years. The majority of those tumors are low-risk, and some studies reported low progression rates of low-risk PTC. It suggests that immediate surgery may not be the best option, specially when considering the intrinsic risk to a thyroidectomy and inconvenience of lifelong hormone replacement. In this systematic review we compare the outcomes of active surveillance for the primary management of low-risk PTC. Methods: The review was conducted based on three studies selected from specific databases. These studies followed up low-risk patients nonoperatively and surgery was performed if needed. Results: All studies reported low percentages of tumor growth and metastatic disease during active surveillance. Furthermore, no significant differences between immediate surgery and late rescue surgery were reported, and active surveillance appears to be cheaper than the tradicional conduct. Conclusions: Active surveillance seems to be a good alternative for low-risk PTC management, yet, more long-term and bigger research is still needed, specially outside of a japanese population.

Fragestellung: Die Bedeutung von Lymphknotenbefall bei papillärem Schilddrüsenkarzinom und die optimale Lymphknotenchirurgie werden kontrovers beurteilt. Methodik: Retrospektive Langzeitstudie eines Operateurs (n = 159), prospektive Dokumentation, Nachkontrolle 1-27 (x = 8) Jahre, Untersuchung mit Bezug auf Lymphknotenbefall. Resultate: Staging. Bei 42 Patienten wurde wegen makroskopischem Lymphknotenbefall (cN1) eine therapeutische Lymphadenektomie durchgeführt, mit pN1 Status bei 41 (98%) Patienten. Unter 117 Patienten ohne Anhalt für Lymphknotenbefall (cN0) fand sich okkulter Befall bei 5/29 (17%) Patienten mit elektiver (prophylaktischer) Lymphadenektomie, und bei 2/88 (2.3%) Patienten ohne Lymphadenektomie (metachroner Befall) (p < 0.005). Lymphknotenrezidive traten (1-5 Jahre nach kurativer Primärtherapie) bei 5/42 (12%) pN1 und bei 3/114 (2.6%) cN0, pN0 Tumoren auf (p = 0009). Das 20-Jahres-Überleben war bei TNM I + II (low risk) Patienten 100%, d.h. unabhängig vom N Status; pN1 vs. pN0, cN0 beeinflusste das Überleben ungünstig bei high risk (>= 45-jährige) Patienten (50% vs. 86%; p = 0.03). Diskussion: Der makroskopische intraoperative Lymphknotenbefund (cN) hat Bedeutung: - Befall ist meistens richtig positiv (pN1) und erfordert eine ausreichend radikale, d.h. systematische, kompartiment-orientierte Lymphadenektomie (Mikrodissektion) zur Verhütung von - kurablem oder gefährlichem - Rezidiv. - Okkulter Befall bei unauffälligen Lymphknoten führt selten zum klinischen Rezidiv und beeinflusst das Überleben nicht. Wir empfehlen eine weniger radikale (sampling), nur zentrale prophylaktische Lymphadenektomie, ohne Risiko von chirurgischer Morbidität. Ein empfindlicherer Nachweis von okkultem Befund (Immunhistochemie, Schnellschnitt von sampling Gewebe oder sentinel nodes) erscheint nicht rational. Bei pN0, cN0 Befund kommen Verzicht auf 131I Prophylaxe und eine weniger intensive Nachsorge in Frage.

Abstract Purpose Recent diagnostic criteria updates of the tall cell variant of papillary thyroid carcinoma (TCPTC) by the World Health Organization (WHO) have determined the inclusion of tumours with 30-49% of tall cells. However, the impact of tall cell percentage on papillary thyroid carcinoma (PTC) patients’ prognosis is still debated. We aimed to evaluate whether tall cell percentage affects patients’ outcome in the absence of aggressive features. Methods Rates of aggressive features, recurrence-free survival (RFS) and distant RFS (DRFS) (5-year median follow-up) were compared among tumours with less than 30%, 30-49% and at least 50% of tall cells. We also evaluated the impact of the new tall cell cut-off on patient management. Results Overall, 3092 tumours (15.7% of all PTC) were collected: 792 PTC had less than 30%, 503 had 30-49%, and 1797 had 50% or more tall cell areas. With the new definition of WHO, the number of TCPTC increased by 28%. There were no differences in recurrence rates according to tall cell percentage. The coexistence of BRAF and TERT promoter mutations predicted a worse RFS. Considering the new definition of TCPTC, the level of risk according to the American Thyroid Association increased from low to intermediate in 4.2% of cases. However, the recurrence rate within this subgroup was comparable to low-risk. Conclusions TCPTC and PTC with tall cell areas can be considered as a unique group with similar recurrence risk. However, whenever aggressive features are absent, tumors have a low risk of recurrence independently of tall cell percentage.

Objective: Here we present 2 cases of papillary thyroid microcarcinomas (PMCs) that had metastasized at presentation. The 2015 American Thyroid Association and the American College of Radiology Thyroid Imaging Reporting and Data System (TI-RADS) criteria do not recommend biopsy of the majority of subcentimeter thyroid nodules, as PMCs are mostly indolent with excellent prognosis. However, the paradigm of active surveillance presents a conundrum on how to identify the rare patient with distant metastatic disease while avoiding unnecessary intervention in the majority. Methods: After initial discovery of incidental lesions on chest computed tomography, core or wedge biopsies of the lung lesion were performed. Thyroid nodules on ultrasound were classified by TI-RADS. Tumor DNA was sequenced, annotated, filtered on 119 known cancer genes, and filtered for variants with an exome allele frequency of <0.001. Results: A 70-year-old woman and a 29-year-old woman presented with incidental pulmonary lesions on computed tomography scan. Lung biopsy revealed lung metastases from papillary thyroid carcinoma. The thyroid nodules in both patients were TI-RADS 3 and American Thyroid Association low-suspicion. Molecular testing showed a c.1721C>G mutation (p.Thr574Ser) in the TSHR gene in patient 1 and a codon 61 mutation in the NRAS gene in patient 2. Both patients were iodine-avid, with complete structural remission in one patient and ongoing treatment with evidence of structural response in the other. Conclusion: The 2 presentations demonstrate unexpected and concerning behavior of PMCs. Both thyroid tumors were subcentimeter in diameter, meaning they would have escaped detection using traditional risk-stratification algorithms in active surveillance. Further knowledge of tumor genetics and microenvironment may assist in predicting tumor behavior in PMCs.
