Management of patients with extensive locally advanced thyroid cancer: results of multimodal treatments.

Purpose: Surgery plays a key role in the treatment of thyroid cancer (TC) patients. Locally advanced cases, however, can require an extensive surgical approach with technical issues and a high risk of complications. In these cases, a multidisciplinary evaluation should be carried out to evaluate pros and cons. The aim of this study was to share our experience, as a multidisciplinary team, in the management of patients with locally advanced TC with a particularly extensive local disease, whose surgical approach could be challenging and part of a multimodal treatment.
Methods: We retrospectively evaluated clinical, surgical, and oncologic features of all patients with locally advanced TC who had undergone multidisciplinary surgery from January 2019 to June 2020.
Results: Six patients (two cases each of poorly differentiated, papillary, and medullary TC) were included. Four out of six were suffering from symptoms related to the advanced disease. At pre-surgical evaluation, a multidisciplinary team proposed extended surgery with radical intent via cervicotomy and sternotomy, considering other therapies not feasible or probably ineffective without it. No one passed away in intra- or perioperative time. At the end of follow-up (median 2.6 years), all patients presented a remission of symptoms due to the advanced disease, four patients were submitted to adjuvant therapies and only one patient died for a cause unrelated to the disease.
Conclusion: This series of very advanced TCs shows the effectiveness of a surgery performed by a multidisciplinary team in controlling symptoms, allowing adjuvant therapies, and improving the survival of patients whose cases would otherwise be very difficult to manage.
