Patients with familial non-medullary thyroid cancer have an outcome similar to that of patients with sporadic papillary thyroid tumors
OBJECTIVE:The purpose of this study was to determine whether familial non-medullary thyroid cancer (FNMTC) is more aggressive than sporadic thyroid cancer. SUBJECTS AND METHODS: We compared the clinical behavior and outcome of 16 subjects with FNMTC from 7 unrelated kindred with those observed in 16...

Summary: | OBJECTIVE:The purpose of this study was to determine whether familial non-medullary thyroid cancer (FNMTC) is more aggressive than sporadic thyroid cancer. SUBJECTS AND METHODS: We compared the clinical behavior and outcome of 16 subjects with FNMTC from 7 unrelated kindred with those observed in 160 subjects with sporadic PTC (SPTC) from our database. RESULTS: The only different baseline characteristics observed between both groups were: bilateral malignancy, 38% vs. 24%, respectively (p = 0.03), and lymph node metastasis, 56.2% vs. 39%, respectively (p = 0.01). Considering the outcome, in the FNMTC, 9 (56.2%) patients were rendered free of disease, one patient died from thyroid cancer (6%), and 6/16 (37.5%) had persistent disease. In the SPTC Group, 87 (54%) patients were considered free of disease, 11 (7%) died due to PTC, and 62 (38%) had persistent disease (p = ns). CONCLUSIONS: Despite the higher incidence of lymph node metastasis in FNMTC patients this situation seemed not to alter the compared outcome.
OBJETIVO: O objetivo deste estudo foi determinar se o câncer de tiroide não medular (CNMF) é mais agressivo do que o câncer esporádico de tiroide. SUJEITOS E MÉTODOS: Comparamos o comportamento clínico e a evolução de 16 portadores de CNMF de sete famílias não relacionadas com 160 CP (câncer papilífero) esporádicos de nosso serviço. RESULTADOS: As únicas diferenças nas características basais dos grupos eram: malignidade bilateral 38% vs. 24%, respectivamente (p = 0,03), e metástases linfonodais, 57,1% vs. 39%, respectivamente (p = 0,01). Em relação à evolução, 9 (56,2%) pacientes com CNMF ficaram livres de doença, um paciente faleceu devido ao CP (6%) e 6/16 (37,5%) apresentavam persistência da doença. No grupo de CP esporádicos, 87 (54%) foram considerados livres de doença, 11 (7%) morreram em decorrência do CP e 62 (38%) apresentavam persistência da doença (p = ns). CONCLUSÃO: Apesar da elevada incidência de metástases linfonodais nos pacientes com CNMF, essa situação não parece alterar a evolução dos dois grupos em longo prazo. |
