Approximately 20% early-stage (I/II) colorectal cancer (CRC) patients develop metastases despite curative surgery. We aim to develop a formalin-fixed and paraffin-embedded (FFPE)-based predictor of metastases in early-stage, clinically-defined low risk, microsatellite-stable (MSS) CRC patients. We considered genome-wide mRNA and miRNA expression and mutation status of 20 genes assayed in 150 fresh-frozen tumours with known metastasis status. We selected 193 genes for further analysis using NanoString nCounter arrays on corresponding FFPE tumours...

PURPOSE: This article examines the outcome of radioactive iodine ablation therapy for thyroid cancer in high-risk patients and investigates background factors influencing ablation failure. MATERIALS AND METHODS: We included 91 patients in this retrospective analysis and evaluated the ablation success rate. Successful ablation was defined as the absence of visible iodine-131 (I-131) accumulation in the thyroid bed after whole-body scans and thyroglobulin levels <2 ng/ml in a TSH-stimulated state after ablation...

Differentiated thyroid cancer (DTC) patients with negative serum thyroglobulin (Tg), negative (131)I whole-body scintigraphy ((131)I-WBS) at first post-ablation and progressively increased TgAb level are a relatively rare entity in the follow-up after total thyroidectomy and radioactive iodine therapy. The value of (18)F-FDG PET/CT in detecting the recurrence of disease in these patients has only been reported in a small case series. The goal of this study was to investigate the diagnostic accuracy of (18)F-FDG PET/CT in detecting recurrent disease in these specific PTC patients and to identify risk factors for patients with positive (18)F-FDG PET/CT results...

INTRODUCTION: The role of adjuvant chemotherapy (AC) for synovial sarcoma (SS) is controversial. Using a large national dataset we evaluate the impact of AC on overall survival (OS) following curative-intent resection of SS. METHODS: Patients with stage I-III SS 2004-2012 undergoing resection were identified in the National Cancer Data Base. Clinicopathologic factors associated with OS were identified using Cox proportional-hazard modeling, adjusting for factors associated with receipt of AC...

Normally, differentiated thyroid cancer (DTC) tends to be biologically indolent, highly curable and has an excellent prognosis. However, the treatment may fail when the cancer has lost radioiodine avidity. The present study was carried out in order to evaluate the cytotoxic and genotoxic effects of (131) I and (60) Co and radioiodine uptake in WRO cells, derived from DTC, harboring the BRAF(V600E) mutation. WRO cells showed a relatively slow cell cycle of 96.3 h with an unstable karyotype containing various double minutes...

The main purpose of this study was to investigate dose rate emanating from patients treated with (131)I to evaluate which of the theoretical formulas, inverse-square law (ISL) and International Atomic Energy Agency-International Commission on Radiological Protection (IAEA-ICRP) suggested equation, can provide a sufficiently close approximation of the measured dose rate. Measurements were performed based on the IAEA safety report No. 63 method at 0, 12, 24, and 48 h after administration of radioiodine at a distance of 1 m for 69 patients and for the rest of 67 patients, dose rate was measured at 2, 4, 24, and 48 h at a distance of 2 m...

The purpose of this work was to develop an optimized liposomal formulation of topotecan for use in the treatment of patients with neuroblastoma. Drug exposure time studies were used to determine that topotecan (Hycamtin) exhibited great cytotoxic activity against SK-N-SH, IMR-32 and LAN-1 neuroblastoma human cell lines. Sphingomyelin (SM)/cholesterol (Chol) and 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC)/Chol liposomes were prepared using extrusion methods and then loaded with topotecan by pH gradient and copper-drug complexation...

Although nanoparticle-based drug delivery systems have been widely explored for tumor-targeted delivery of radioisotope therapy (RIT), the hypoxia zones of tumors on one hand can hardly be reached by nanoparticles with relatively large sizes due to their limited intratumoral diffusion ability, on the other hand often exhibit hypoxia-associated resistance to radiation-induced cell damage. To improve RIT treatment of solid tumors, herein, radionuclide (131) I labeled human serum albumin (HSA)-bound manganese dioxide nanoparticles ((131) I-HSA-MnO2 ) are developed as a novel RIT nanomedicine platform that is responsive to the tumor microenvironment (TME)...

PURPOSE: Tall cell (TCV) and diffuse sclerosing (DSV) variants are aggressive variants of papillary thyroid cancer (PTC). We compared the risk of recurrent/persistent disease in patients with TCV, DSV and classical PTC (cPTC) and evaluated the prognostic accuracy of initial vs. ongoing risk stratification. METHODS: A consecutive series of DSV (n = 54), TCV (n = 72) and cPTC (n = 184) patients was retrospectively analyzed. TCV and DSV patients were first risk stratified for recurrent/persistent disease without considering the histotype as a risk factor and subsequently, 6-24 months after initial treatment, re-classified on the basis of the response to therapy (ongoing risk stratification)...

This study set out to investigate chromosomal damage in peripheral blood lymphocytes of thyroid cancer patients receiving (131)I for thyroid remnant ablation or treatment of metastatic disease. The observed chromosomal damage was further converted to the estimates of whole-body dose to project the adverse side effects. Chromosomal aberration analysis was performed in 24 patients treated for the first time or after multiple courses. Blood samples were collected before treatment and 3 or 4 days after administration of 2-4 GBq of (131)I...

BACKGROUND: In our previous SMC NB-2004 study of patients with high-risk neuroblastomas, which incorporated total-body irradiation (TBI) with second high-dose chemotherapy and autologous stem cell transplantation (HDCT/auto-SCT), the survival rate was encouraging; however, short- and long-term toxicities were significant. In the present SMC NB-2009 study, only TBI was replaced with (131)I-meta-iodobenzylguanidine (MIBG) treatment in order to reduce toxicities. METHODS: From January 2009 to December 2013, 54 consecutive patients were assigned to receive tandem HDCT/auto-SCT after nine cycles of induction chemotherapy...

OBJECTIVE: Post-operative thyroglobulin (Tg) levels can predict the likelihood of residual cancer, including distant metastases, thereby influencing postsurgical treatment strategies even in patients with low-risk disease. Circulating anti-thyroglobulin antibodies (anti-Tg Abs) interfere with Tg measurement preventing this clinical use. It is not known if the presence of anti-Tg Abs predicts metastatic disease on post-therapy scan in patients with low-risk disease or if they should influence the use or dose of I-131 therapy...

To assess the efficacy of radioiodine therapy (RIT) and investigate the prognostic factors for patients with pulmonary metastasis secondary to differentiated thyroid carcinoma (DTC) through a retrospective study. A total of 80 patients with radioactive iodine-131 (I)-avid pulmonary metastasis from DTC treated with I from 2007 to 2014 at our institution entered the study. Treatment response was mainly measured by two parameters: serum thyroglobulin (Tg) levels and post-therapeutic I whole-body scan (WBS). Treatment variables were assessed for statistical significance using the univariate and multivariate analyses...

Gliomas, the most prevalent type of brain tumor in adults, are associated with high rates of morbidity and mortality. Recent studies on (131)I labeled scorpion toxins suggest they can be developed as tumor-specific agents for glioma diagnosis and treatment. This study investigated the potential of (131)I labeled Buthus martensii Karsch chlorotoxin ((131)I-BmK CT) as a new approach for targeted imaging and therapy of glioma. The results showed that (131)I can be successfully linked to BmK CT with satisfactory radiochemical purity and stability and that (131)I-BmK CT markedly inhibited glioma cell growth in a dose and time dependent manner, with significant accumulation in glioma cells in vitro...

PSMA-targeted radiotherapy of prostate cancer (PCa) has emerged recently as a promising approach to the treatment of disseminated disease. A small number of ligands have been evaluated in patients, and while early tumor response is encouraging, relapse rate is high, and these compounds localize to the parotid, salivary and lacrimal glands as well as the kidney, leading to dose-limiting toxicities and adverse events affecting quality of life. We envision that dual targeting ligands displaying high affinity for PSMA and appropriate affinity for human serum albumin (HSA) may demonstrate a higher therapeutic index and be suitable for treatment of PCa by targeted alpha therapy (TAT)...
