Abstract

Background: Radioactive iodine (RAI) therapy is a cornerstone in the management of differentiated thyroid cancer (DTC). However, a subset of patients develops RAI-refractory disease, characterized by the inability to concentrate radioiodine, leading to limited treatment options and a poorer prognosis. This study aimed to investigate the prevalence and identify potential risk factors associated with RAI-refractory DTC in an Indonesian population. Methods: A retrospective analysis was conducted on patients diagnosed with DTC and treated with RAI at a single tertiary care center in Indonesia between 2019 and 2023. Data on demographics, clinical characteristics, tumor features, and treatment outcomes were collected. RAI-refractoriness was defined as the absence of iodine uptake on diagnostic whole-body scans after cumulative RAI activity of 600 mCi or more. Bivariate and multivariate analyses were performed to identify risk factors for RAI-refractoriness. Results: A total of 194 patients with DTC were included in the study. The prevalence of RAI-refractoriness was 90%. The median age at diagnosis was 55 years (range 18-82), and 72% were female. Papillary thyroid carcinoma was the most common histological subtype (92%). In bivariate analysis, older age at diagnosis (p=0.02), male gender (p=0.04), and the presence of distant metastases at diagnosis (p<0.001) were significantly associated with RAI-refractoriness. In multivariate analysis, only the presence of distant metastases remained an independent predictor of RAI-refractoriness (odds ratio 3.8, 95% confidence interval 1.5-9.2, p=0.003). Conclusion: RAI-refractoriness is a significant clinical challenge in the management of DTC, with a high prevalence observed in this Indonesian cohort. The presence of distant metastases at diagnosis emerged as a strong predictor of RAI-refractoriness. Further research is needed to elucidate the underlying mechanisms of RAI-refractoriness and develop novel therapeutic strategies for this patient population.

Abstract

Background: Triple-negative breast cancer (TNBC) is an aggressive subtype with limited treatment options. Neoadjuvant chemotherapy (NAC) is often used to downstage tumors before surgery, but response rates vary. This meta-analysis aims to identify factors that influence TNBC’s response to NAC. Methods: PubMed, Embase, and Cochrane Library databases were searched (2018-2024) for studies evaluating factors associated with TNBC response to NAC. Data on patient demographics, tumor characteristics, NAC regimens, and response rates were extracted. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects models. Results: Twenty-three studies (n=4,512 patients) were included. Younger age (OR 1.82, 95% CI 1.35-2.46), smaller tumor size (OR 0.58, 95% CI 0.41-0.82), lower clinical stage (OR 0.39, 95% CI 0.27-0.56), and absence of lymph node involvement (OR 0.42, 95% CI 0.31-0.57) were associated with improved pathological complete response (pCR) rates. NAC regimens containing platinum agents (OR 2.15, 95% CI 1.54-2.99) and immune checkpoint inhibitors (OR 1.78, 95% CI 1.23-2.58) also showed higher pCR rates. Conclusion: This meta-analysis identified several factors associated with improved TNBC response to NAC, including younger age, smaller tumor size, lower clinical stage, absence of lymph node involvement, and use of platinum-based or immunotherapy-containing NAC regimens. These findings can inform patient selection and treatment optimization for NAC in TNBC.
