Aim: To investigate the prognostic value of pre-ablation stimulated thyroglobulin (ps-Tg) in children and adolescents with persistent differentiated thyroid cancer (DTC) following initial radioiodine therapy (RAI).
Materials & Methods: Patients were classified into "no clinical evidence of disease" (NED), "biochemical persistent disease" (BPD), and "structural/functional persistent disease" (S/FPD) groups, based on their therapeutic response to initial RAI. BPD patients were further categorized as incomplete response (IR) or Non-IR; S/FPD patients were categorized as remission or Non-remission.
Purpose: This two-center study aimed to explore the main prognostic factors affecting the final disease status in children and adolescents with differentiated thyroid cancer (caDTC) following total thyroidectomy and radioiodine therapy (RAIT).
Materials And Methods: All caDTC patients from two centers in the period from 2004-2022 were retrospectively included. At the last follow-up, the patients' disease status was assessed and classified as an incomplete response (IR) or as an excellent or indeterminate response (EIDR).
Objective: We aimed to explore the predictive value of stimulated thyroglobulin (sTg) and pre-ablation antithyroglobulin (pa-TgAb) products for the effect of radioiodine therapy (RAIT) on TgAb-positive differentiated thyroid cancer (DTC) patients.
Methods: In this study, we enrolled 265 patients with TgAb-positive DTC who underwent RAIT after total thyroidectomy (TT). Based on the last follow-up result, the patients were divided into two groups: the excellent response (ER) group and the non-excellent response (NER) group.
Background: I treatment is one of the important methods of comprehensive postoperative treatment for patients with hyperthyroidism complicated with differentiated thyroid cancer (DTC). Early identification of patients with poor treatment efficacy of I is particularly important. Current studies mainly focus on the relationship between hyperthyroidism and the occurrence and development of DTC, and there are few studies on the factors affecting the curative effect.

A total of 182 patients with intermediate- and high-risk PTC who underwent RT in our hospital from March 2018 to October 2020 were retrospectively enrolled. The patients were divided into incomplete response (IR) and nonincomplete response (Non-IR) groups according to the response observed in clinical follow-up within 6-12 months after RT.

- The study aimed to evaluate the effectiveness and safety of a combined treatment of microwave ablation (MWA) and transcatheter arterial chemoembolization (TACE) for patients with colorectal liver metastases (CRLM).
- It involved 30 patients, where treatment responses were assessed via follow-up imaging; results showed an 81.4% complete ablation rate and high overall response rate of 83.4%.
- The study concluded that this treatment approach is safe, with no major complications, and offers a viable option for managing CRLM, despite a median overall survival of 11 months.
Purpose: To evaluate the safety and efficacy of microwave (MW) ablation combined with transarterial chemoembolization in a single stage for the treatment of large (≥ 5 cm) hepatocellular carcinoma (HCC).
Materials And Methods: From March 2013 to January 2015, 66 patients (54 men and 12 women; mean age, 54 y; range, 29-83 y) with 72 large HCC lesions were included in this study. Eighteen (27.
