2 Apesar da quase benignidade da evolução tumoral do carcinoma diferenciado da tiroideia
A invasão laringo-traqueal é da ordem dos 7%. A invasão local das vias aéro-digestivas superiores é causa de uma considerável morbilidade e mortalidade. 95% dos doentes falecidos, apresentam uma doença local activa. 23 de Abril 2015 IPOFG / JRS

Shindo ML1, Caruana SM, Kandil E, McCaffrey JC, Orloff LA, Porterfield JR, Shaha A, Shin J, Terris D, Randolph G. CONCLUSIONS Only with proper preoperative evaluation, a high index of suspicion for invasion, and the surgical expertise for complete resection with low morbidity, patients with invasive well-differentiated thyroid cancer are likely to be given the best opportunity for survival and low risk of recurrence. Gross disease resection is an underlying theme throughout the literature for thyroid cancer in general and for invasive disease specifically, which is reflected in the statements offered here for which consensus was achieved. For invasive disease, complete resection can result in a plethora of important functional deficits, which must be considered as the surgical plan is engaged, especially as it relates to the commonly affected recurrent nerve and airway. Such decision-making is best formatted by an experienced surgeon in the context of a multidisciplinary team including endocrinology, laryngology, radiology, nuclear medicine, radiation oncology, medical oncology, and, most importantly, the patient and their family. In these discussions, oncologic completeness is balanced with surgical morbidity, with an understanding of the patient's disease status, distant progression, comorbidities, and wishes.

8 Extrathyroidal thyroid cancer : results of tracheal shaving and tracheal resection].
Brauckhoff M1, Dralle H. 1Department of Surgical Sciences, University of Bergen, Norway. Abstract Extrathyroidal thyroid cancer invading the laryngotracheal system (UICC stage pT4a) represents a progressive process of infiltration of the tracheal wall layers from the outer to the inner parts of the trachea. These tumors usually present with high proliferation activity correlating with a reduced long-term prognosis. In contrast to intraluminal manifestation requiring complete wall resection, in cases of non-transmural invasion, complete tumor removal can be sometimes achieved by extraluminal tangential resection (shaving). Tangential resections, however, are associated with a higher frequency of microscopically invaded resection margins (R1 resection rate >40%). The available comparative studies (all retrospective, maximum EBM level 3) analyzing oncological outcome show inconsistent results. In more recently published studies, however, complete wall resection in well-differentiated thyroid cancer with tracheal invasion only was found to be associated with longer recurrence-free and tumor-specific survival when compared to shaving. Deep larynx invasion is associated with reduced long-term prognosis when compared to invasion of the trachea. Salvage resections should therefore be performed in selected cases only.

9 Molecular, morphologic, and outcome analysis of thyroid carcinomas according to degree of extrathyroid extension. Rivera M1, Ricarte-Filho J, Tuttle RM, Ganly I, Shaha A, Knauf J, Fagin J, Ghossein R. 1Department of Pathology, Memorial Sloan-Kettering Cancer Center, 1275 York Ave., New York, NY 10065, USA. Abstract BACKGROUND: The impact of varying degrees of extrathyroid extension (ETE), especially microscopic ETE (METE), on survival in thyroid carcinomas (TC) has not been well established. Our objective was to analyze ETE at the molecular and histologic levels and assess the effect of its extent on outcome. CONCLUSION: (i) PTCs with METE have an extremely low recurrence rate in contrast to tumors with gross ETE. (ii) High mitotic activity and/or tumor necrosis confers worse DSS even in patients stratified for gross ETE in trachea/esophagus. (iii) BRAF positivity correlates with the presence of ETE in PTC, but this relationship is lost within classical/tall cell PTC if follicular variants are excluded from the analysis.

10 The management of thyroid carcinoma invading the larynx or trachea.
Honings J1, Stephen AE, Marres HA, Gaissert HA. 1Division of Thoracic Surgery, Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts 02114, USA. RESULTS: Invasion of the larynx or trachea by thyroid carcinoma is uncommon and often identified at the time of operation, when the surgeon must decide the extent of resection. Invasion of the airway is associated with loss of tumor differentiation and a reduction in long-term survival compared to tumors limited to the thyroid gland. Whether or not the invaded airway should be resected remains controversial. Tangential shave excision of tumor is commonly performed, despite a marked risk of local recurrence. Circumferential sleeve resection of the larynx and trachea is safe and lowers the risk of local recurrence. In recurrent disease, laryngotracheal resection provides effective palliation of airway obstruction and hemoptysis. CONCLUSIONS: Long-term (>10-20 years) prospective studies are required to compare the outcome after shave excision with segmental airway resection for thyroid carcinoma. Based on the current literature and on our experience, we advocate circumferential tracheal resection in the setting of airway involvement. 23 de Abril 2015 IPOFG / JRS

Aerodigestive tract invasion by well-differentiated thyroid carcinoma: McCaffrey JC1. 1Department of Interdisciplinary Oncology, University of South Florida School of Medicine, H. Lee Moffitt Cancer Center and Research Institute, Tampa, Florida 3612, USA. RESULTS: Basic science: a significant difference between the three thyroid tissue groups for E-cadherin expression was demonstrated on one-way ANOVA testing. When controls were compared with either experimental group in post hoc ANOVA testing, differences between all groups were demonstrated (P < .001). For beta-catenin, the intensities of the three groups were not different by one-way ANOVA testing. Similar nonsignificant results were found on post hoc ANOVA testing. Clinical: there was a statistically significant difference in survival for patients with and without involvement of any portion of the endolarynx or trachea (P < .01). There was a significant difference among all three surgical groups when compared (P < .001). When complete and shave groups were compared with gross residual group there was a significant decrease in survival in incomplete resection group (P < .01). Cox regression analysis demonstrated invasion of larynx and trachea were significant prognostic factors for poor outcome. The type of initial resection was significant on multivariate analysis. Removal of all gross disease is a major factor for survival.

13 TRATAMENTO CIRURGICO DAS FORMAS INVASIVAS DE CARCINOMA DIFERENCIADO DA TIROIDEIA
A ressecção laringotraqueal e a reconstrução aerodigestiva, evita a morte por asfixia e permite uma paliação prolongada, com boa qualidade de vida dos doentes. Nos doentes que apresentam uma invasão da traqueia, deveremos encarar a possiblidade de uma ressecção mais ampla que o “shaving” da cartilagem (R1>40% - Henning Dralle) com a objectivo de aumentarmos a probabilidade de cura dos doentes. Deveremos complementar a ressecção radical do tumor com radioterapia externa e/ou com I131 Diferenciação, idade do doente, rediferenciação com retinoides 23 de Abril 2015 IPOFG / JRS
