Objective Childhood cancer survivors (CCS) are at increased risk to develop differentiated thyroid cancer predominantly after radiotherapy (subsequent DTC). It is insufficiently known whether subsequent DTC in CCS has a different presentation or outcome than sporadic DTC. Methods Patients with subsequent DTC (n = 31) were matched to patients with sporadic DTC (n = 93) on gender, age and year of diagnosis to compare presentation and DTC outcomes. Clinical data were collected retrospectively. Results Among the CCS with subsequent DTC, all but one had received chemotherapy for their childhood cancer, 19 (61.3%) had received radiotherapy including the thyroid region, 3 (9.7%) 131I-MIBG and 8 (25.8%) had received treatment with chemotherapy only. Subsequent DTC was detected by surveillance through neck palpation (46.2%), as a self-identified mass (34.6%), or by chance. Among sporadic DTC patients, self detection predominated (68.8%). CCS with subsequent DTC tended to have on average smaller tumors (1.9 vs 2.4 cm, respectively, (P = 0.051), and more often bilateral (5/25 (60.0%) vs 28/92 (30.4%), P = 0.024). There were no significant differences in the occurrence of surgical complications, recurrence rate or disease-related death. Conclusion When compared to patients with sporadic DTC, CCS with subsequent DTC seem to present with smaller tumors and more frequent bilateral tumors. Treatment outcome seems to be similar. The finding that one-third of subsequent DTC cases had been treated with chemotherapy only needs further investigation. These results are important for the development of surveillance programs for CCS at risk for DTC and for treatment guidelines of subsequent DTC.

Purpose We developed three absolute risk models for second primary thyroid cancer to assist with long-term clinical monitoring of childhood cancer survivors. Patients and Methods We used data from the Childhood Cancer Survivor Study (CCSS) and two nested case-control studies (Nordic CCSS; Late Effects Study Group). Model M1 included self-reported risk factors, model M2 added basic radiation and chemotherapy treatment information abstracted from medical records, and model M3 refined M2 by incorporating reconstructed radiation absorbed dose to the thyroid. All models were validated in an independent cohort of French childhood cancer survivors. Results M1 included birth year, initial cancer type, age at diagnosis, sex, and past thyroid nodule diagnosis. M2 added radiation (yes/no), radiation to the neck (yes/no), and alkylating agent (yes/no). Past thyroid nodule was consistently the strongest risk factor (M1 relative risk [RR], 10.8; M2 RR, 6.8; M3 RR, 8.2). In the validation cohort, 20-year absolute risk predictions for second primary thyroid cancer ranged from 0.04% to 7.4% for M2. Expected events agreed well with observed events for each model, indicating good calibration. All models had good discriminatory ability (M1 area under the receiver operating characteristics curve [AUC], 0.71; 95% CI, 0.64 to 0.77; M2 AUC, 0.80; 95% CI, 0.73 to 0.86; M3 AUC, 0.75; 95% CI, 0.69 to 0.82). Conclusion We developed and validated three absolute risk models for second primary thyroid cancer. Model M2, with basic prior treatment information, could be useful for monitoring thyroid cancer risk in childhood cancer survivors.

e21528 Background: Thyroid cancer is a common secondary malignancy among childhood cancer survivors who have received radiation to the head, neck and/or upper thorax. The optimal strategy for surveillance for thyroid carcinoma in childhood cancer survivors remains controversial. Current Children’s Oncology Group recommendations are limited to physical exam. The objective of this study was to determine the sensitivity and specificity of thyroid ultrasound versus neck exam by a pediatric endocrinologist in the diagnoses of thyroid cancer in a cohort of high-risk childhood cancer survivors. Methods: Medical records of childhood cancer survivors who received radiotherapy to the head, neck and/or upper thorax were reviewed. These patients were seen in a comprehensive childhood cancer survivorship clinic from 01/01/2010 to 12/31/2017. Patient populations included oncology, bone marrow transplant and brain tumor patients. Results: 226 patients received radiation to the head, neck and/or upper thorax. Of those, 129 patients were male (57%). Sixteen (7.1%) of patients developed a secondary thyroid malignancy including 4 patients previously treated for an oncological malignancy, 9 patients treated with bone marrow transplantation, and 3 patients with a CNS malignancy. Median radiation dose was 1800 cGy (range 400-5940 cGy). Time to thyroid carcinoma diagnosis occurred at a median of 12 years (range 4-19 years) from treatment with radiation. Screening ultrasounds were obtained in 146 (65%) patients while 226 (100%) had a physical exam. Two cases were identified by abnormalities on physical exam. The sensitivity of US was 100% (CI 80.6-100) compared to a sensitivity of 12.5% (CI 3.5-36) using physical exam (P < 0.0001). Screening ultrasound had a specificity of 73% (CI 65.1-80.1) while physical exam yielded a specificity of 100% (CI 98.2-100). Conclusions: Regular screening with ultrasounds provide the greatest sensitivity for detection of secondary thyroid carcinomas after head, neck and upper thorax radiation in childhood cancer survivors. If screening ultrasounds were not routinely utilized in our clinic, 14 of the 16 patients (87.5%) would have had a delay in their diagnosis of a secondary thyroid malignancy. Screening ultrasounds may lead to earlier detection of thyroid carcinomas, with the potential to decrease the need for aggressive surgery, radioiodine therapy and, ultimately, to decrease recurrence risk.

Clinical Considerations

The incidence of differentiated thyroid carcinoma (DTC) has increased rapidly over the past several years. Thus far, the only conclusively established risk factor for developing DTC is exposure to ionizing radiation, especially when the exposure occurs in childhood. Since the number of childhood cancer survivors (CCS) is increasing due to improvements in treatment and supportive care, the number of patients who will develop DTC after surviving childhood cancer (secondary thyroid cancer) is also expected to rise. Currently, there are no recommendations for management of thyroid cancer specifically for patients who develop DTC as a consequence of cancer therapy during childhood. Since complications or late effects from prior cancer treatment may elevate the risk of toxicity from DTC therapy, the medical history of CCS should be considered carefully in choosing DTC treatment. In this paper, we emphasize how the occurrence and treatment of the initial childhood malignancy affects the medical and psychosocial factors that will play a role in the diagnosis and treatment of a secondary DTC. We present considerations for clinicians to use in the management of patients with secondary DTC, based on the available evidence combined with experience-based opinions of the authors.
