RESUMO
INTRODUCTION: Over the past years, the incidence of thyroid cancer has surged not only in Germany but also in other countries of the Western hemisphere. This surge was first and foremost due to an increase of prognostically favorable ("low risk") papillary thyroid microcarcinomas, for which limited surgical procedures are often sufficient without loss of oncological benefit. These developments called for an update of the previous practice guideline to detail the surgical treatment options that are available for the various disease entities and tumor stages. METHODS: The present German Association of Endocrine Surgeons practice guideline was developed on the basis of clinical evidence considering current national and international treatment recommendations through a formal expert consensus process in collaboration with the German Societies of General and Visceral Surgery, Endocrinology, Nuclear Medicine, Pathology, Radiooncology, Oncological Hematology, and a German thyroid cancer patient support organization. RESULTS: The practice guideline for the surgical management of malignant thyroid tumors includes recommendations regarding preoperative workup; classification of locoregional nodes and terminology of surgical procedures; frequency, clinical, and histopathological features of occult and clinically apparent papillary, follicular, poorly differentiated, undifferentiated, and sporadic and hereditary medullary thyroid cancers, thyroid lymphoma and thyroid metastases from primaries outside the thyroid gland; extent of thyroidectomy; extent of lymph node dissection; aerodigestive tract resection; postoperative follow-up and surgery for recurrence and distant metastases. CONCLUSION: These evidence-based recommendations for surgical therapy reflect various "treatment corridors" that are best discussed within multidisciplinary teams and the patient considering tumor type, stage, progression, and inherent surgical risk.

INTRODUCTION: Benign thyroid disorders are among the most common diseases in Germany, affecting around 15 million people and leading to more than 100,000 thyroid surgeries per year. Since the first German guidelines for the surgical treatment of benign goiter were published in 1998, abundant new information has become available, significantly shifting surgical strategy towards more radical interventions. Additionally, minimally invasive techniques have been developed and gained wide usage. These circumstances demanded a revision of the guidelines. METHODS: Based on a review of relevant recent guidelines from other groups and additional literature, unpublished data, and clinical experience, the German Association of Endocrine Surgeons formulated new recommendations on the surgical treatment of benign thyroid diseases. These guidelines were developed through a formal expert consensus process and in collaboration with the German societies of Nuclear Medicine, Endocrinology, Pathology, and Phoniatrics & Pedaudiology as well as two patient organizations. Consensus was achieved through several moderated conferences of surgical experts and representatives of the collaborating medical societies and patient organizations. RESULTS: The revised guidelines for the surgical treatment of benign thyroid diseases include recommendations regarding the preoperative assessment necessary to determine when surgery is indicated. Recommendations regarding the extent of resection, surgical techniques, and perioperative management are also given in order to optimize patient outcomes. CONCLUSIONS: Evidence-based recommendations for the surgical treatment of benign thyroid diseases have been created to aid the surgeon and to support optimal patient care, based on current knowledge. These recommendations comply with the Association of the Scientific Medical Societies in Germany requirements for S2k guidelines.
