Objectives. Invasion of differentiated thyroid cancer (DTC) into surrounding structures can lead to morbid procedures such as laryngectomy and tracheal resection. In these patients, there is a potential role for neoadjuvant therapy.Methods. We identified three studies involving the treatment of DTC with neoadjuvant chemotherapy: two from Slovenia and one from Japan.Results. These studies demonstrate that in selected situations, neoadjuvant chemotherapy can have a good response and allow for a more complete surgical resection, the treatment of DTC. Additionally, the SELECT trial shows that the targeted therapy lenvatinib is effective in the treatment of DTC and could be useful as neoadjuvant therapy for this disease due to its short time to response. Pazopanib has also demonstrated promise in phase II data.Conclusions. Thus, chemotherapy in the neoadjuvant setting could possibly be useful for managing advanced DTC. Additionally, some of the new tyrosine kinase inhibitors (TKIs) hold promise for use in the neoadjuvant setting in DTC.

e17589 Background: Describe the treatment patterns of patients initiated on NCCN-recommended small molecular kinase inhibitors (SMKIs) for radioiodine-refractory differentiated thyroid cancer (DTC) approved in the United States. Methods: A large national US claims database was used to identify adult patients diagnosed with thyroid cancer (≥2 non-DX medical claims, ≥ 30 days apart) from 1/1/2006 - 6/30/2016 (study period) with claims for SMKIs from 1/1/2010 - 5/31/2016. Continuous enrollment required participation in a commercial or Medicare Advantage health plan ≥3 months before and ≥1 month following index date (date of first pharmacy claim for SMKI). Line of therapy (LOT) periods were defined by receipt and timing of SMKIs. Patient follow up was earliest disenrollment, death or end of the study period. Patient characteristics and SMKI treatment patterns were described. Results: A total of 217 DTC patients were identified; 63% commercially insured and 37% Medicare Advantage. Almost half were male (48%); mean age was 61.2 years (standard deviation SD 12.5 years) and mean follow-up period was 499 days (SD 414 days). In the study period, 35% (n = 77) of patients had ≥2 LOTs and 18% (n = 39) had ≥3 LOTs. Mean treatment duration was 5.4 months (SD 6.7 mos) for LOT1, 4.9 months (SD 3.8 mos) for LOT2, and 4.2 months (SD 4.9 mo) for LOT3. During the full study period, the most used regimens were Sorafenib for both LOT1 (37%) and LOT2 (25%), pazopanib (18%) and sunitinib (18%) in LOT3. Also, in the study period, 33 patients had sorafenib in LOT1 of which 16 were treated with sorafenib again (48%) in LOT2. Post FDA approval in 2015, Lenvatinib became the predominant first-line regimen (47%, n = 29) during study period. Across all first line therapies, for those patients with ≥12 months of follow-up, 53% (n = 60) initiated LOT2. Conclusions: Sorafenib was the most common first line of therapy for DTC, with Lenvatinib adoption increasing as first-line therapy since the drug’s approval in 2015. Depending on the period evaluated, almost half to 2/3 of patients are not receiving a second line of treatment, efficacious and patient appropriate therapy is of importance in treating this rare cancer.

Liver metastases from differentiated thyroid carcinoma (LMDTC) are rare and usually occur in disseminated metastatic disease. The aim of this study was to review the diagnosis and management of LMDTC. Between 1995 and 2011, 14 patients with a mean age of 59.7 years (+/-10.2) were treated for LMDTC. Data were retrospectively reviewed and analyzed. Seven patients had distant metastases at diagnosis, including 2 with synchronous liver lesions. The average time of onset of LMDTC from initial diagnosis was 52.2 months (+/49.5). All LMDTC were discovered during routine radiologic monitoring. Histologic analysis confirmed LMDTC in 5 patients. Eight patients received tyrosine kinase inhibitors, 1 patient underwent resection of their LMDTC after chemotherapy. Six patients (disseminated metastases, significant comorbidities) did not receive any specific treatment. The median survival after diagnosis of LMDTC was 17.4 months (+/-3.3): 23.6 months (+/-2.9) for patients who underwent chemotherapy versus 3.9 months (+/-0.9) for patients who did not receive any specific treatment (P < 0.001). Developing DTC liver metastasis is a very poor prognostic sign. Chemotherapy by TKIs, especially, hold promise in the cure of LMDTC for selected patients.

Differentiated thyroid cancer is a common malignancy with an excellent prognosis. Patients typically present with a thyroid nodule identified on physical exam or imaging. Fine needle aspiration (FNA) is the diagnostic modality of choice; ultrasound of the neck is used preoperatively to evaluate lymphadenopathy. Surgery is the mainstay of treatment, with partial or total thyroidectomy (with or without lymphadenectomy). Intra-operatively, identification of the recurrent laryngeal nerve and preservation of the parathyroid glands is imperative. Postoperatively, patients are considered for adjuvant radioactive iodine ablation. Risk stratification systems are available to assist patient selection for therapy. Surveillance is completed with serial physical exams, laboratory studies, ultrasound, and radioactive iodine scanning. Recurrence can be managed with surgery, thyroid-stimulating hormone suppression, radioactive iodine ablation, radiation, or kinase inhibitors.  This review contains 8 figures, 6 tables, and 50 references.  Key Words: Bethesda classification, differentiated thyroid cancer, follicular thyroid cancer, papillary thyroid cancer, radioactive iodine, thyroid nodule, thyroidectomy

Background. Current management of treating iodine-negative metastases of differentiated thyroid cancer has its features. In recent years, tyrosine kinase inhibitors (sorafenib, sunitinib) have been registered and indicated to treat refractory forms of differentiated thyroid cancer in Ukraine. However, there were only few studies dealing with cytologic aspects of predicting radioiodine resistance of papillary thyroid cancer, development of radionuclide monitoring and diagnostic algorithm to detect relapses and metastases in patients with iodine-negative forms of differentiated thyroid cancer. At the same time, scientific and clinical aspects of treatment of radioiodineresistant differentiated thyroid cancer in Ukrainian oncology and radiology are barely studied. Thus, the status of treatment and post-therapeutic monitoring of patients with iodine-negative forms of differentiated thyroid cancer, still remains insufficiently studied and requires further scientific and clinical development. Purpose – develop a technique of treatment of iodine-negative metastases of differentiated thyroid cancer. Materials and methods. Thirty-eight patients with iodine-negative metastases of differentiated thyroid cancer were provided with treatment, where in 10 patients the efficiency of treatment was assessed by means of whole body scintigraphy with 99mTc-MIBI, in 10 patients – with 99mTcDMCA. In 10 patients the short-term results of treatment with tyrosine kinase inhibitors were evaluated by PET with 18F-FDG. Eight patients represented a group where the bones were affected and treatment was provided by means of radionuclide or external-beam radiotherapy. The average age of patients varied from 43 to 76, the median was 57.8 + 3.9; out of those: 24 women, 14 men. Pathohistologically, papillary cancer was diagnosed in 31, follicular – in 5, papillary-follicular – in 2. The studies were performed by means of the two-detector gamma camera manufactured by Mediso (Hungary) and the single-photon emission computed tomography (SPECT) E. CAM 180, Siemens (Germany). PET/CT were performed on the Biograph-64-TruePoint-Siemens combined tomograph (Germany), according to the guidelines of the European Association of Nuclear Physicians. Results. Prior to initiating therapy, 10 patients with differentiated thyroid cancer underwent whole body scintigraphy with 99mTc-MIBI and re-examination in three months in order to assess treatment success. After diagnostic examination, the patient was prescribed targeted therapy with Nexavar according to the treatment protocol. Regression of the focus in the lungs was achieved within 70 %. Further monitoring of antitumor treatment success was performed by means of whole body scintigraphy with 99mTc-MIBI. Ten patients, who had PET/CT with 18F-FDG made before treatment, also underwent targeted therapy by means of Nexavar. Diagnostic scanning with 18F-FDG after therapy revealed decreased functional activity of the lesion in the neck, however no decrease in the dimensions of the lesion was observed. Conclusions. Treatment of iodine-negative metastases of differentiated thyroid cancer by means of tyrosine kinase inhibitors was accompanied by a decreasing number of metastatic foci and reducing level of their functional activity. The studies have confirmed the possibility of applying techniques with non-iodine RP (99mTc-MIBI, 99mTc-DMCA) to assess the effectiveness of treatment of iodine-negative metastases of differentiated thyroid cancer . PET/CT with 18F-FDG is a highly informative technique for assessing the effect of tyrosine kinase inhibitors on the functional activity of metastatic foci according to metabolic scans in treatment of iodine-negative metastases of differentiated thyroid cancer. If there are no positive changes after 3–4 courses, external-beam radiotherapy with total radiation dose of 30–50 Gy is indicated, which is capable of reducing the volume of metastatic foci as well as their metabolic activity. The social and economic significance of the obtained findings have made it possible to improve the overall and recurrence-free survival rates in the working population of patients with differentiated thyroid cancer and reduce the cost of following-up patients with iodine-negative forms of differentiated thyroid cancer.

6077 Background: Antiangiogenic tyrosine kinase inhibitors (TKIs) represent the first-line treatment for radioiodine-refractory differentiated thyroid cancer (RR-DTC). Currently, no predictive factors for the activity of these drugs are available. We investigated whether radiomics may have a predictive role in this setting. Methods: We retrospectively identified patients (pts) affected by metastatic RR-DTC, treated with TKIs between July 2008 and January 2020 at our Institution, with availability of computed tomography (CT) scans at baseline and after at least 2 courses of TKI. Response to TKIs was evaluated according to RECIST v1.1. Pts with complete or partial response at the first radiological evaluation were considered responders (R), pts with stable or progressive disease non-responders (NR). A dedicated radiologist segmented the target lesions as regions of interest (ROIs). Radiomic features related to multiple categories (shape and size, first order statistics, textural features) were extracted from each ROI and computed using the PyRadiomics library v. 3.0. A semi-supervised form of principal component analysis estimated principal components that were then used for response classification through a k nearest neighbors (kNN) classifier. The quality of the model was assessed through train-validation-test split (55% of the data used as training set, 25% as validation set, 20% as test set), repeated 100 times. Performance of the predictive models was quantified with the mean Area Under the ROC Curve (AUC) obtained in the test set. Results: A total of 51 pts with metastatic RR-DTC who had received lenvatinib (n=37), sorafenib (n=4), axitinib (n=3), or vandetanib (n=7) were analyzed. Median age was 64.6 years, with a male prevalence (72.5%). Metastatic sites were lung (84.3%), bone (35.3%), brain (9.9%). Median time from TKI treatment start to the first radiological evaluation was 2.77 months, 24 pts (47%) were R (all partial responses) and 27 (52.9%) NR. In the radiomic analysis, 851 features were computed and 4-19 principal components were selected. Models’ performance of prediction of early response to TKIs is presented in Table. For each value of AUC, the corresponding 95% confidence interval is reported in brackets. Conclusions: Radiomics predicted the response to TKIs of RR-DTC pts with an accuracy of 71%. Radiomics technique has the potential to enable clinicians to anticipate the probability of response to TKIs at baseline, directing toward the most suitable patient-tailored therapeutic path. Prospective studies may further validate these preliminary findings.[Table: see text]
