Objective: Radioactive iodine (RAI) is used to ablate residual thyroid tissue after total thyroidectomy. The aim of this study was to evaluate the response according to the12th-month results of thyroid cancer patients and to investigate the changes in response level during follow-up. Materials and Methods: The study included 97 patients, comprising 88 (90.7%) females and 9 (9.3%) males, with a mean age of 41.68±13.25 years. None of the patients had lymph node or distant metastasis and all received RAI therapy. Thyroid-stimulating hormone (TSH), thyroglobulin (TG), and anti-TG levels and neck USG were examined in the 12th-month. Response to therapy was evaluated as an excellent response, biochemical incomplete response, structural incomplete response, or indeterminate response. Results: In the 12th month, 80 patients (82.47%) had excellent response, 13 patients (13.40%) had an indeterminate response, 3 patients (3.09%) had structural incomplete response and 1 patient (1.03 %) had biochemical incomplete response. Of the 80 patients with excellent response, 15 had no follow-up after the 12th month. The remaining 65 patients were followed up for 31.11±9.58 months. The response changed to indeterminate in the 18th month in 1 (1.54%) patient and to structural incomplete response in the 35th month in 1 (1.54%) patient. The 13 patients with indeterminate responses were followed up for 20.61±6.28 months. Conclusion: The TG level at 12th months provides accurate data about the course of the disease especially in patients with excellent responses. Patients with excellent response in the 12th month may be followed up less often and those with the indeterminate or incomplete responses should be followed up more often.

Abstract Context The risk of persistent and recurrent disease in patients with differentiated thyroid cancer (DTC) is a continuum that ranges from very low to very high, even within the three primary risk categories. It is important to identify independent clinicopathological parameters to accurately predict clinical outcomes. Objective To examine the association between pre-ablation stimulated thyroglobulin (ps-Tg) and persistent and recurrent disease in DTC patients and investigate whether incorporation of ps-Tg could provide a more individualized estimate of clinical outcomes. Design, Setting, and Participants Medical records of 2524 DTC patients who underwent total thyroidectomy and radioiodine ablation between 2006 and 2018 were retrospectively reviewed. Main Outcome Measure Ps-Tg was measured under thyroid hormone withdrawal before remnant ablation. Association of ps-Tg and clinical outcomes. Results In multivariate analysis, age, ATA risk stratification, M1, ps-Tg and cumulative administered activities were the independent predictive factors for persistent/ recurrent disease. Receiver operating characteristic analysis identified ps-Tg cutoff (≤ 10.1 ng/mL) to predict disease free status with a negative predictive value of 95%, and validated for all ATA categories. Integration of ps-Tg into ATA risk categories indicated that the presence of ps-Tg ≤ 10.1 ng/mL was associated with a significantly decreased chance of having persistent/recurrent disease in intermediate- and high-risk patients (9.9 to 4.1% in intermediate-risk patients, and 33.1 to 8.5% in high-risk patients). Conclusion Ps-Tg (≤ 10.1 ng/mL) was a key predictor of clinical outcomes in DTC patients. Its incorporation as a variable in the ATA risk stratification system could more accurately predict clinical outcomes.

Risk Stratification System

Objective Recent research suggests that the addition of age improves the 2015 American Thyroid Association (ATA) Risk Stratification System for differentiated thyroid cancer (DTC). The aim of our study was to investigate the influence of age on disease outcome in ATA High Risk patients with a focus on differences between patients with papillary (PTC) and follicular thyroid cancer (FTC). Methods We retrospectively studied adult patients with High Risk DTC from a Dutch university hospital. Logistic regression and Cox proportional hazards models were used to estimate the effects of age (at diagnosis) and several age cutoffs (per five years increment between 20 and 80 years) on (i) response to therapy, (ii) developing no evidence of disease (NED), (iii) recurrence, and (iv) disease specific mortality (DSM). Results We included 236 ATA High Risk patients (32% FTC) with a median follow-up of 6 years. Age, either continuously or dichotomously, had a significant influence on having an excellent response after initial therapy, developing NED, recurrence, and DSM for PTC and FTC. For FTC, an age cutoff of 65 or 70 years showed the best statistical model performance, while this was 50 or 60 years for PTC. Conclusions In a population of patients with High Risk DTC, older age has a significant negative influence on disease outcomes. Slightly different optimal age cutoffs were identified for the different outcomes, and these cutoffs differed between PTC and FTC. Therefore, the ATA Risk Stratification System may further improve should age be incorporated as an additional risk factor.

Purpose The phosphoinositide-3-kinase (PI3K), phosphatase and tensin homolog (PTEN), v-akt murine thymoma viral oncogene homolog (AKT), and mammalian target of rapamycin (mTOR) signaling pathway has been implicated in resistance to several chemotherapeutic agents. In this retrospective study, we determined whether common genetic variations in this pathway are associated with clinical outcomes in esophageal cancer patients with adenocarcinoma or squamous cell carcinoma who have undergone chemoradiotherapy and surgery. Patients and Methods Sixteen tagging single nucleotide polymorphisms (SNPs) in PIK3CA, PTEN, AKT1, AKT2, and FRAP1 (encoding mTOR) were genotyped in these patients and analyzed for associations with response to therapy, survival, and recurrence. Results We observed an increased recurrence risk with genetic variations in AKT1 and AKT2 (hazard ratio [HR], 2.21; 95% CI, 1.06 to 4.60; and HR, 3.30; 95% CI, 1.64 to 6.66, respectively). This effect was magnified with an increasing number of AKT adverse genotypes. In contrast, a predictable protective effect by PTEN genetic variants on recurrence was evident. Survival tree analysis identified higher-order interactions that resulted in variation in recurrence-free survival from 12 to 42 months, depending on the combination of SNPs. Genetic variations in AKT1, AKT2, and FRAP1 were associated with survival. Patients homozygous for either of the FRAP1 SNPs assayed had a more than three-fold increased risk of death. Two genes—AKT2 and FRAP1—were associated with a poor treatment response, while a better response was associated with heterozygosity for AKT1:rs3803304 (odds ratio, 0.50; 95% CI, 0.25 to 0.99). Conclusion These results suggest that common genetic variations in this pathway modulate clinical outcomes in patients who undergo chemoradiotherapy. With further validation, these results may be used to build a model of individualized therapy for the selection of the optimal chemotherapeutic regimen.
