Objective: In this study, we aimed to investigate the clinical features of Papillary thyroid carcinoma(PTC) Tall cell variant(TCV), long-term outcomes and surgical experience in papillary thyroid carcinoma., Material-Method: 33 patients who were operated in our clinic between August 2012 and March 2018 and diagnosed as TCV in their pathology evaluation were included in the study. The demographic and clinical features of the patients, pathological features of the tumor and long-term results were examined., Results: A total of 33 patients were included in our study. The mean age was 55.2(18-85) years. The female sex was more dominant (75.8%). The most common presenting complaint was swelling in the neck (75.7%).Total thyroidectomy was performed in 84.8% and completion thyroidectomy after lobectomy was performed in 15.2%. Neck dissection was performed in 33% of the patients. The mean tumor diameter was 3.6 (1-10) cm. The tumor was multifocal in 36.3% of the patients. The capsule invasion rate of the tumors was present in 69.7% of the patients, extrathyroidal rate was 39.4%, Metastatic lymph nodes were detected in 30.3% of the cases. The mean follow-up duration was 39.3+22.4(5.25-78.63) months. 39.4% of patients had distant metastasis during follow-up. Disease free survival rate was 57.6%, total survival was 42.4 + 3.8 (34.7-50.0) months., Conclusion: TCV is closely associated with larger tumor diameter, multifocal location, extrathyroidal spread and lymph node involvement, We believe that more aggressive surgery should be performed in the treatment of TCV cases and it is important to follow up the patients more closely., Key Word: Esophagus cancer, Neutrophil/lymphocyte ratio, Preoperative lymphocyte /neutrophil ratio, Prognosis.

Objective: The aim of this study is to share the efficacy of the radionuclide occult lesion localization (ROLL) technique in secondary neck exploration in patients who had undergone neck exploration due to thyroid or parathyroid pathology and to share our clinical experience., Material and Method: Data of 25 patients who underwent secondary neck exploration for recurrent thyroid cancer and parathyroid adenoma between January 2016 and December 2018 at the General Surgery Clinic of Balcalı Hospital, Çukurova University Faculty of Medicine were collected retrospectively. On the operation day, 0.5 mCi Tc-99m macroaggregate albumin was injected into the lesion under ultrasound guidance (USG). Nerve monitoring was used in all patients., Results: Twenty-five patients (21 females, 4 males) were included in the study. The mean age of the patients was 54.5 (24-79) years. Five patients were operated for parathyroid adenoma, 6 patients for papillary cancer after subtotal thyroidectomy, 13 patients for papillary cancer recurrence, 2 patients for medullary cancer recurrence, 2 patients for papillary cancer cervical lymph node metastasis and 1 patient for anaplastic cancer recurrence.Mean operative time was 100.6 min (60-160 min). Two patients had transient hypocalcemia and no other complications were seen. Parathyroid hormone (PTH) levels in patients with hyperparathyroidism, Thyroglobulin (Tg) levels in patients with recurrent papillary cancer, were significantly lower than preoperative levels (p<0.05)., Conclusion: We believe that ROLL technique reduces the complication rate by decreasing dissection time and width. We recommend using it for thyroid cancer and parathyroid redo surgery., Key Words: Parathyroid redo surgery, Radioguided surgery, Thyroid cancer.
