Abstract Purpose: To determine the predictive capability of MRI-based radiomics for extrathyroidal extension detection in papillary thyroid cancer (PTC) pre-surgically.Methods: The present retrospective trial assessed individuals with thyroid nodules examined by multiparametric MRI and subsequently administered thyroid surgery. Diagnosis and extrathyroidal extension (ETE) feature of PTC were based on pathological assessment. The thyroid tumors underwent manual segmentation, for radiomic feature extraction. Participants were randomized to the training and testing cohorts, at a ratio of 7:3. The mRMR (maximum correlation minimum redundancy) algorithm and the least absolute shrinkage and selection operator (LASSO) were utilized for radiomics feature selection. Then, a radiomics predictive model was generated via a linear combination of the features. The model’s performance in distinguishing the ETE feature of PTC was assessed by analyzing the receiver operating characteristic (ROC) curve. Results: Totally 132 patients were assessed in this study, including 92 and 40 in the training and test cohorts, respectively). Next, the 16 top-performing features, including 4, 7 and 5 from diffusion weighted (DWI), T2-weighted (T2 WI), and contrast-enhanced T1-weighted (CE-T1WI) images, respectively, were finally retained to construct the radiomics signature. There were 8 RLM, 5 CM, 2 shape, and 1 SZM features. The radiomics prediction model achieved AUCs of 0.96 and 0.87 in the training and testing sets, respectively.Conclusions: Our study indicated that MRI radiomics approach had the potential to stratify patients based on ETE in PTCs preoperatively.

Objective: Clinical practice for differentiated thyroid cancer is moving towards lobectomy rather than total thyroidectomy in patients at low risk of recurrence. However, recurrence risk assessment depends on post-operative findings, while the surgical decision is based on preoperative factors. We determined the preoperative predictors of occult higher-risk pathology and rates of completion thyroidectomy among surgical candidates with nonbenign thyroid nodules 10 to 40 mm and no evidence of extrathyroidal extension or metastasis on preoperative evaluation. Methods: Thyroid surgery cases at a single institution from 2005–2015 were reviewed to identify those meeting American Thyroid Association (ATA) criteria for lobectomy. ATA-based risk stratification from postoperative surgical pathology was compared to preoperative cytopathology, ultrasound, and clinical findings. Results: Of 1,995 thyroid surgeries performed for nonbenign thyroid nodules 10 to 40 mm, 349 met ATA criteria for lobectomy. Occult high-risk features such as tall cell variant, gross extrathyroidal invasion, or vascular invasion were found in 36 cases (10.7%), while intraoperative lymphadenopathy led to surgical upstaging in 13 (3.7%). Intermediate risk features such as moderate lymphadenopathy or minimal extrathyroidal extension were present in an additional 44 cases. Occult risk features were present twice as often in Bethesda class 6 cases (35%) as in lower categories (12 to 17%). In multivariable analysis, Bethesda class and nodule size, but not age, race, sex, or ultrasound features, were significant predictors of occult higher-risk pathology. Conclusion: Most solitary thyroid nodules less than 4 cm and with cytology findings including atypia of undetermined significance through suspicious for papillary thyroid cancer would be sufficiently treated by lobectomy.

Preliminary Study

Objective: Thyroid cancer can be detected in 5–10% of patients with thyroid nodules. Management may be a challenge if fine-needle aspiration biopsy yields Bethesda III findings. Most of these cases undergo surgery and are ultimately found benign. Our aim was to evaluate whether serum osteopontin can accurately estimate thyroid cancer risk in cases with cytologically Bethesda III thyroid nodules and, thereby, decrease the number of unnecessary surgical interventions. Design and Methods: We obtained blood samples of cases with repeated cytologically Bethesda III thyroid nodules before surgery, and followed up the pathology results after thyroidectomy. We evaluated serum osteopontin from 36 patients with papillary thyroid cancer and compared them with 40 benign cases. Results: Serum osteopontin levels in patients with papillary thyroid cancer are significantly higher than in benign cases (mean serum osteopontin: 10.48 ± 3.51 ng/mL vs 6.14 ± 2.29 ng/mL, p<0.001). The area under the receiver operating characteristics curve was 0.851, suggesting that serum osteopontin could have considerable discriminative performance. Conclusions: In our preliminary study, high serum osteopontin levels can predict the risk of papillary thyroid cancer in thyroid nodules with Bethesda III cytology. Further studies are necessary to confirm these findings.

Functional Autonomy

The rate of nodular goiter in children ranges from 0.05 to 5.1%; in this case, the risk of thyroid cancer in childhood amounts to 3―70% of all cases of thyroid pathology. Therefore, the main issue is the differential diagnosis of a nosological variant of a thyroid nodule, which defines the optimal therapeutic tactics for a particular patient. The risk of malignancy is traditionally believed to be low in the case of decompensated functional autonomy of a thyroid nodule; therefore, the need for fine needle aspiration biopsy (FNAB) followed by cytomorphological analysis of the aspirate is avoided in most cases. The presented clinical case demonstrates papillary cancer in an adolescent with a toxic single nodular goiter. A thyroid ultrasound examination revealed a nodular lesion in the boy. An increase in the thyroid size and thyrotoxicosis manifestation occurred 3 years later. A cytomorphological study identified follicular neoplasia; scintigraphy revealed a hot nodule. Surgical treatment was planned. Antithyroid therapy was prescribed to prepare for surgery. After compensation of thyrotoxicosis, hemithyroidectomy was performed. A histological examination diagnosed papillary thyroid cancer, which required repeated thyroidectomy followed by radioiodine I131 ablation. The postoperative period was uneventful; the patient well tolerated suppressive levothyroxine therapy. Therefore, the presence of a toxic single nodular goiter does not exclude thyroid cancer, which defines the need to discuss the indications for FNAB of thyroid nodules in children.
