The incidence of thyroid cancer has been steadily increasing over the past several decades worldwide. (1,2) It is projected that, by 2030, thyroid cancer will become the fourth most common [...], Background: It remains unclear how thyroid surgical oncologic quality indicators (TSOQIs) are related to each other, and how to best interpret and apply these measures within the context of surgical quality assurance. We aimed to examine the relation between 3 TSOQIs: postoperative serum thyroglobulin level, 24-hour radioactive iodine uptake (RAIU) and metastatic lymph node ratio (MLNR). Methods: We conducted a retrospective review of patients who underwent total thyroidectomy for treatment of papillary thyroid cancer (PTC) performed by a single high-volume thyroid surgeon at a tertiary referral centre between 2012 and 2017. To establish the strength of correlation between pairs of quality indicators and the MACIS (metastasis, age, completeness of resection, invasion and size) prognostic score, we performed tests of normality and used the Spearman correlation coefficient to determine the correlation of nonnormal data containing outliers. Results: A total of 139 patients with PTC were included in the study. Their mean MACIS score was 5.0 (standard deviation 1.5). Fifteen patients had high-risk thyroid cancer (MACIS score > 6.99). A weak correlation was found between serum thyro globulin level and RAIU (rs = 0.27, p = 0.006) and a moderate correlation was found between serum thyroglobulin level and MLNR (rs = 0.40 p = 0.002). A weak correlation between serum thyroglobulin level and MACIS score was also observed (rs = 0.20, p = 0.05). Conclusion: Based on our findings, we propose that the postoperative serum thyroglobulin level represents the quality metric that has the most clinical utility because it is measurable in all patients and also correlates with both RAIU and MLNR. With further research, surgeons seeking to evaluate the oncologic quality of thyroidectomy performed for PTC may consider applying a quality indicator to their future practice. Contexte : On ignore encore comment les indicateurs de la qualite des soins en oncochirurgie pour la thyroide (IQSOCT) sont interrelies et comment interpreter et appliquer le mieux possible ces mesures dans le contexte de l'assurance de la qualite en soins chirurgicaux. Nous avons voulu examiner le lien entre 3 IQSOCT : taux de thyroglobuline serique postoperatoire, absorption de l'iode radioactif (AIRA) en 24 h et taux de ganglions lymphatiques metastatiques (TGLM). Methodes : Nous avons procede a une revue retrospective des patients soumis a une thyroidectomie totale pour le traitement d'un cancer papillaire de la thyroide (CPT) operes par le meme chirurgien specialiste de la thyroide dans un centre de soins tertiaires entre 2012 et 2017. Pour etablir la solidite de la correlation entre les paires d'indicateurs de la qualite et le score pronostique MACIS (metastasis, age, completeness of resection, invasion and size), nous avons procede a des tests de normalite et utilise le coefficient de correlation de Spearman pour determiner la correlation des donnees non normales renfermant des valeurs aberrantes. Resultats : En tout, 139 patients atteints de CPT ont ete inclus dans l'etude. Leur score MACIS moyen etait de 5,0 (ecart-type 1,5). Quinze patients presentaient un cancer de la thyroide a risque eleve (score MACIS > 6,99). Une faible correlation a ete observee entre le taux de thyroglobuline serique et l'AIRA (rs = 0,27, p = 0,006) et une correlation moderee entre le taux de thyroglobuline serique et le TGLM (rs = 0,40, p = 0,002). Nous avons note egalement une faible correlation entre le taux de thyroglobuline serique et le score MACIS (rs = 0,20, p = 0,05). Conclusion : Selon nos observations, nous estimons que le taux de thyroglobuline serique postoperatoire represente l'indicateur de qualite le plus utile au plan clinique parce qu'il est mesurable chez tous les patients et qu'il est egalement en correlation avec l'AIRA et le TGLM. A mesure que la recherche s'approfondira, les chirurgiens qui souhaitent evaluer la qualite oncologique de la thyroidectomie pour le CPT pourraient envisager d'appliquer un indicateur de qualite a leur pratique future.
