    The Relationship Between Thyroid Volume and Malignant Thyroid Disease
    (2014) Duran, Ayse Ocak; Anil, Cuneyd; Gursoy, Alptekin; Nar, Asli; Altundag, Ozden; Inanc, Mevlude; Bozkurt, Oktay; Tutuncu, Neslihan Bascil; https://orcid.org/0000-0003-3802-9733; https://orcid.org/0000-0003-0998-8388; https://orcid.org/0000-0003-0197-6622; https://orcid.org/0000-0002-1816-3903; 24338169; AAA-2743-2021; W-9219-2019; ABG-5027-2020
    The present retrospective study aimed to investigate the relationship between thyroid volume and prevalence of thyroid cancer. We investigated the data of 3,850 patients who underwent fine-needle aspiration biopsy (FNAB). Biopsy results were evaluated as diagnostic or nondiagnostic, and diagnostic results were classified as benign, malignant, and indeterminate. We included 2,672 patients who underwent FNAB firstly in our hospital and evaluated as diagnostic biopsy except subgroup of indeterminate. We obtained cytologic data, levels of serum thyroid-stimulating hormone (TSH), and thyroid volumes of those patients retrospectively. Among 2,672 patients with thyroid nodule, 2,562 (95.9 %) patients had benign cytology and 110 (%4,1) patients had malignant cytology. There was no correlation between the malignancy and gender (p = 0.935), and patients with malignant cytology were younger (52 vs 59, p < 0.001). Also, TSH levels were higher in patients with malignant than benign cytology (p = 0.017). Median volume of right part, left part, and total thyroid for patients who had malignant cytology was significantly lower than patients who had benign cytology (8.3, 7.1, 15.9 vs 10.8 ml, 9.0 mml, 20.6 ml, respectively, p <= 0.001 for all parameters). The results demonstrated that thyroid cancer prevalence was higher in patients with low thyroid volume. According to our results, thyroid volume should be considered as a risk factor for malignancy in the evaluation of thyroid nodules.

    Retrospective Analysis of Patients with Synchronous Primary Breast and Thyroid Carcinoma
    (2018) Arer, Ilker Murat; Yabanoglu, Hakan; Kus, Murat; Aldur, Aydincan; Avci, Tevfik; 0000-0002-8726-3369; 0000-0002-1161-3369; 0000-0001-5225-959X; 0000-0001-6529-7579; 29774315; AAA-3068-2021; AAJ-7865-2021; AAF-1698-2021; AAJ-7870-2021
    Objective: Breast and thyroid cancers are commonly encountered malignancies. Increased risk of breast cancer in follow-up period of thyroid cancer or vice versa has been reported. However, they have some associations, synchronous presentation of these tumors is rare. We presented 12 patients diagnosed as breast and thyroid cancer and treated at the same time. Materials and Methods: Mastectomy and thyroidectomy were performed in 19 patients at the same time. 7 patients were excluded because of benign thyroid pathology. Therefore 12 patients who had diagnosis of synchronous breast and thyroid cancer were included. Data regarding clinical, pathological, treatment and prognostic factors was retrospectively analyzed. Results: Total thyroidectomy was performed in all patients. The mean age of patients was 54 years (min. 44-max. 70). Only one patient was male. Thyroid pathology was detected preoperatively by FDG PET-CT scan in 11 patients. Breast reconstruction was performed in three patients. The most commonly seen thyroid malignancy was papillary thyroid carcinoma. Postoperative complication rate was 33.3%. Adjuvant chemotherapy was given in 11 patients whereas one patient received adjuvant radiotherapy. Conclusion: Although synchronous presentation of breast and thyroid cancer is rare, surgical treatment of both of these tumors can be safely performed at the same time. Association of these tumors should be evaluated by large scaled studies.
