Sorafenib Prolongs Progression-free Survival of Metastatic Differentiated Thyroid Cancer Patients  by Five Months

Background. The implementation of tyrosine kinase inhibitors into clinical practice improved treatment outcomes in patients with radioiodine-refractory differentiated thyroid cancer (RR-DTC). Lenvatinib is recommended as a first-line drug for these patients. The study objective is to analyze clinical experience with lenvatinib in patients with RR-DTC in the Russian Federation. Materials and methods. The data from 18 clinical sites in Russia was analyzed for the period December 2015 and September 2019. Seventyseven patients with histologically verified DTC, proven resistance to radioactive iodine therapy, and tumor progression (according to the Response Evaluation Criteria In Solid Tumors 1.1 criteria) were included in the study. Results.Median progression-free survival in patients included into analysis (n = 72) was 26.1 months. In patients who responded to therapy (including those with partial and complete response), median progression-free survival reached 36.2 months, which is higher than that reported in the updated results of the SELECT study (33.1 months). Lenvatinib-associated adverse events (AEs) were observed in 87 % of patients. Severe AEs were registered in 18.2 % of participants. In 6.5 % of cases, AEs lead to lenvatinib cessation; in 74 % of cases, AEs required dose reduction.Conclusion. Our findings suggest high efficacy and good tolerability of lenvatinib in patients with RR-DTC in routine clinical practice in the Russian Federation.

Abstract Context The recommendations for radioiodine therapy (RAIT) in metastatic differentiated thyroid cancer (DTC) are mostly based in the experience with papillary histotype and do not consider the differences within the distinct types of DTC, in terms of RAIT uptake and response. Objective To investigate the association between histology and RAIT avidity and response; to evaluate whether histotype was an independent prognostic factor in progression-free survival (PFS) and disease-specific survival (DSS) after RAIT for distant metastatic disease. Design Retrospective analysis of all DTC patients submitted to RAIT due to distant metastatic disease, between 2001-2018. Setting Thyroid cancer referral centre. Patients We included 126 patients: 42 (33.3%) classical variant papillary thyroid cancer (cvPTC), 45 (35.7%) follicular variant PTC (fvPTC), 17 (13.5%) follicular thyroid cancer (FTC) and 22 (17.5%) Hürthle-cell carcinoma. Main outcome measures RAIT avidity and response. Results RAIT avidity was independently associated with histology (p<0.001) and stimulated thyroglobulin at first RAIT for distant lesions (p=0.007). Avidity was lowest in HCC (13.6%), intermediate in cvPTC (21.4%), and highest in fvPTC (75.6%) and FTC (76.5%). Regarding RAIT response, HCC and FTC were not different; both showed significantly more often progression after RAIT than fvPTC and cvPTC. Histology influenced PFS (p=0.014), but tumour type was not a significant prognostic factor in DSS. Instead, age at diagnosis, resection status, and stimulated thyroglobulin at the first RAIT were significantly associated with DSS. Conclusion DTC histotype influenced RAIT avidity and PFS. It is crucial to better detect the metastatic patients that may benefit the most from RAIT.

Abstract Purpose There is no sufficient data about the clinical course and outcome in thyroid cancer patients who become pregnant after diagnosis of distant metastasis (DM). The current study was conducted to collect information regarding the clinical and reproductive characteristics, and outcomes in thyroid cancer patients who became pregnant after being diagnosed with DM. Methods Records of 125 differentiated thyroid cancer (DTC) patients with age ≤ 45 years at DM diagnosis who had visited Ito Hospital from January 2005 to June 2021 were retrospectively reviewed. Among those 125 patients, 28 who became pregnant after DM diagnosis were classified as pregnant group, and the remained 97 patients were classified as comparator group. Results In pregnant group, the median age at malignancy diagnosis, DM diagnosis, and first pregnancy after DM diagnosis was 25 years (range, 4–41 years), 27 years (range, 11–41 years), and 32 years (range, 25–45 years), respectively. Fifty-five pregnancies and 40 live births were reported. Three patients had live births by embryo transfer. Other pregnancy outcomes were miscarriage (n = 14) and induced abortion (n = 1). No one died during the follow-up period in this study. The 10-year progression free survival (PFS) rates of pregnant and comparator group were 92.1% and 74.4%, respectively. Conclusion DTC patients who became pregnant after DM diagnosis had good survival. Our results add to the information required for counseling thyroid cancer patients who have concerns about their fertility in the future.

Abstract BACKGROUND Age has been identified as a major prognostic factor in differentiated thyroid cancer (DTC). Prognostic factors of radioiodine-refractory differentiated thyroid cancer (RAIR-DTC) are poorly described. The objectives of our study were to analyze the influence of age on the survival of patients with RAIR-DTC and to determine their prognostic factors according to age. PATIENTS AND METHOD This single centre, retrospective study enrolled 155 patients diagnosed with a RAIR-DTC between 1991 and 2017. The primary end point was overall survival (OS). Secondary endpoints were progression free survival (PFS) and prognostic factors. RESULTS Median OS was 8.2 years (95% IC: 5.3-9.6). There was no difference according to age (P = 0.47) with median OS at 8.3 years in patients < 65 (95% IC: 4.9-10), and 7.5 years in patients > 65 (IC: 4,9-11,3). PFS after RAIR-diagnosis was 2.1 years (95% IC: 0.8-3) in patients < 65, and 1 year in patients > 65 (95% IC: 0.34-0.68). In both groups, progressive disease despite 131I reduced OS, in comparison with other RAIR criteria. In patients < 65, an interval between the initial diagnosis of DTC and the diagnosis of RAIR metastatic disease more than 3 years was protective from poor OS (HR: 2.12; 95% CI: 1.05-4.27). In patients > 65, presence of a mediastinum metastasis at RAIR-diagnosis was a significant factor for decreased OS (HR: 0.22; 95% CI: 0.11-0.44). No difference was found between groups regarding therapeutic management. One third of patients received tyrosine kinase inhibitors in both groups (< 65 years: 20 patients (28%), ≥ 65 years: 28 (33%), P = 0.49). They were also similar regarding the number of lines received or the median duration of treatment (< 65 years: 19.5 months (2-59), ≥ 65 years: 19 months (1-64), p= 0.35). At least one line of TKI was transitorily or definitively withdrawn due to toxicity in 40% of patients (< 65 years: 8/20 patients (40%), ≥ 65 years: 13/28 (46%), p= 0,037). CONCLUSION In RAIR-DTC patients, age was not predictive of the outcome. In our study, older patients seem to have benefited from intensive therapeutic management. Continual progress made in the management of RAIR-DTC, especially with the implementation of systemic therapies should probably make reconsider the natural history and conventional prognostic factors of RAIR-DTC.
