Randomised controlled trial of in- versus out-patient management of benign hemithyroidectomy.

INTRODUCTION: Outpatient (OPT) thyroid surgery is increasing, with patient selection being pivotal for safety. While numerous studies exist, most are retrospective and encompass both benign and malignant cases. METHODS: We conducted a randomised clinical trial on patients undergoing hemithyroidectomy for benign thyroid disease. Participants were assigned to OPT or inpatient groups. We collected data on complications, failure to discharge on surgery day, post-operative pain, nausea, sleep quality and patient satisfaction. RESULTS: Among 97 patients, 27.5% (14/51) in the OPT group could not be discharged on the day of surgery due to minor complications, primarily nausea (36%) and neck swelling (29%). No reoperations were needed. Though OPT patients exhibited a higher rate of minor complications (29%), they reported less post-operative nausea, better sleep and a faster return to normal activity. CONCLUSIONS: Discharge on the day of surgery is not always possible with OPT thyroid surgery. However, our findings suggest that OPT hemithyroidectomy for benign cases can be both safe and feasible for a selected group of patients. FUNDING: None TRIAL REGISTRATION.

Substantial intrinsic variability in chemoradiosensitivity of newly established anaplastic thyroid cancer cell-lines.

Background: Well characterized human cell lines are needed for preclinical treatment studies of anaplastic thyroid cancer (ATC).Aims/Objectives: The aim was to establish, verify and characterize a panel of ATC cell lines.Material and methods: Cell lines were established from ATC fine-needle aspiration biopsies and characterized genetically and functionally regarding treatment sensitivities.Results: Eight cell lines were established in vitro and the anaplastic thyroid origin was verified. Seven of the cell lines were also grown as xenografts. The cell lines harboured complex karyotypes with modal numbers in hyperdiploid to near-pentaploid range. Five were TP53 mutated and three carried the BRAFV600E mutation. None had rearrangements of RET. For doxorubicin, IC50 ranged from 0.42 to 46 nmol/L and for paclitaxel from 1.6 to 196 nmol/L. Radiation sensitivity varied between 2.6 and 6.3 Gy. Two of the BRAF mutated cell lines displayed high sensitivity to vemurafenib, while the third was similar to the wild-type ones.Conclusions and significance: We describe a series of new ATC cell lines demonstrating large heterogeneity in the response to cytostatic drugs and the BRAF inhibitor vemurafenib. The observations are relevant to future attempts to optimize treatment combinations for ATC.

Rate of recurrence and malignant transformation in 88 cases with inverted papilloma between 1998-2008.

Conclusions The recurrence rate of IP in the current study is comparable to international and national studies. When the primary tumour was located in the frontal or the sphenoid sinus, the tumour seemed more likely to recur. Some recurrences were more than 2 years after primary surgery, suggesting continued need for long-term follow-up. The rate of malignant transformation in inverted papilloma cases has not changed in Denmark. Objectives Inverted papillomas are benign tumours located in the nasal cavity and paranasal sinuses. They are known for their tendency to recur after surgery and show invasive growth, causing bone remodulation and the association with malignant transformation. The introduction of endoscopic sinus surgery and computer aided sinus surgery over the last decades has made this tumour more approachable with less cosmetic and functional damage. The objective of this study is to establish whether the recurrence rate and the rate of malignant transformation of IP have changed with the application of these new techniques. Method A retrospective study between 1998-2008 including 88 cases with inverted papilloma. Results In total, 25.3% had recurrence. Combined surgical approach with endoscope/open approach had the lowest rate of recurrence. A malignant transformation in the postoperative histological examination was found in 8.9%.
