Background: En bloc kidney transplantation (EBKT) involves transplantation of two kidneys, the aorta, and inferior vena cava from a deceased pediatric donor into an adult recipient. Recent articles have shown that EBKT is associated with excellent long-term allograft performance and patient survival. Developmental differences exist between the two transplanted kidneys after EBKT, and it is crucial to assess split renal function.

In this case, we present a patient who underwent achalasia surgery and subsequently exhibited abnormal 131 I uptake on SPECT/CT imaging. The patient was a known case of papillary thyroid carcinoma that suggested to 131 I therapy.

A remarkable body of new data establishes that many degenerative brain diseases and some acute injury situations in the brain may be associated with ferroptosis. In recent years, ferroptosis has also attracted great interest in the cancer research community, partly because it is a unique mode of cell death distinct from other forms and thus has great therapeutic potential for brain cancer. Glioblastoma is a highly aggressive and fatal human cancer, accounting for 60% of all primary brain tumors.

Anaplastic thyroid cancer (ATC) is a rare but highly aggressive kind of thyroid cancer. Various therapeutic methods have been considered for the treatment of ATC, but its prognosis remains poor. With the advent of the nanomedicine era, the use of nanotechnology has been introduced in the treatment of various cancers and has shown great potential and broad prospects in ATC treatment.

Donafenib, an oral tyrosine kinase inhibitor (TKI), showed good efficacy and tolerability in the phase II study. We aimed to further evaluate the antitumor activity and safety of donafenib in Chinese patients with RAIR-DTC.

The kidney is a vital organ responsible for maintaining homeostasis in the human body. However, renal cell carcinoma (RCC) is a common malignancy of the urinary system and represents a serious threat to human health. Although the overall survival of RCC has improved substantially with the development of cancer diagnosis and management, there are various reasons for treatment failure.

Methods: The baseline F-FDG PET/CT images of 126 patients with grade 1-3A FL were retrospectively analyzed. A novel PET/CT parameter characterizing lesion dissemination, the distance between two lesions that were furthest apart ( ), was calculated.
Cutaneous and subcutaneous soft tissue metastases are rare in lung adenocarcinoma and suggest poor prognosis. We report a patient with lung adenocarcinoma who initially presented with cutaneous and subcutaneous metastases to the abdomen that were initially presumed to be herpes zoster and an occult subcutaneous soft tissue mass. Because the lesions progressed over 3 weeks despite routine herpes zoster treatment, magnetic resonance imaging was performed and showed a presumed sarcoma; however, F-fluourodeoxyglucose positron emission tomography/computed tomography demonstrated pulmonary lesions.

Methods: Totally, 64 DTC patients were enrolled with 24 in the dose-escalation cohort equally grouped into 0.9 mg × 1 day, 0.
Background: Photodynamic therapy (PDT) is a promising antitumor strategy with fewer adverse effects and higher selectivity than conventional therapies. Recently, a series of reports have suggested that PDT induced by Cerenkov radiation (CR) (CR-PDT) has deeper tissue penetration than traditional PDT; however, the strategy of coupling radionuclides with photosensitizers may cause severe side effects.
Methods: We designed tumor-targeting nanoparticles (I-EM@ALA) by loading 5-aminolevulinic acid (ALA) into an I-labeled exosome mimetic (EM) to achieve combined antitumor therapy.
Pulmonary epithelioid hemangioendothelioma (EHE) is a rare vascular malignancy that is typically low-to-intermediate grade. We report a 47-year-old man with a rapidly progressive pulmonary EHE who initially presented with asymptomatic pulmonary nodules. One nodule was mildly hypermetabolic on initial F-FDG PET/CT.

Methods: RNA sequencing (RNA-seq) data of PTC and normal tissues were downloaded from The Cancer Genome Atlas (TCGA) database with clinical stage data to form a test, validation, and clinical-stage data matrix.
Importance: Patients with radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC) have a poor prognosis and limited treatment options.
Objective: To assess the efficacy and safety of apatinib, a highly selective vascular endothelial growth factor (VEGFR-2) inhibitor, in patients with progressive locally advanced or metastatic RAIR-DTC.
Design, Setting, And Participants: This randomized, double-blind, placebo-controlled, phase 3 trial (Efficacy of Apatinib in Radioactive Iodine-refractory Differentiated Thyroid Cancer [REALITY]) was conducted in 92 patients with progressive locally advanced or metastatic RAIR-DTC between February 17, 2017, and March 2, 2020, at 21 sites within China, and the data cutoff date for this analysis was March 25, 2020.
We explored the clinical value of F-FDG PET/MR in a head-to-head comparison with PET/CT in loco-regional recurrent and metastatic cervical lymph nodes of differentiated thyroid carcinoma (DTC) patients after comprehensive treatment. F-FDG PET/CT and neck PET/MR scans that were performed in DTC patients with suspected recurrence or cervical lymph node metastasis after comprehensive treatment were retrospectively analyzed. Detection rates, diagnostic efficacy, image conspicuity, and measured parameters were compared between F-FDG PET/CT and PET/MR.

The relationship between F-FDG PET/MR and serum Tg levels was explored. We also evaluated the therapeutic impact of PET/MR on patient clinical management.

We aimed to develop nomograms for individualized estimates of progression-free survival (PFS) and overall survival (OS) in patients with ENKTL using F-FDG PET/CT parameters and clinical parameters.
Methods: A total of 171 patients with newly diagnosed ENKTL undergoing F-FDG PET/CT scanning were retrospectively analyzed.
Purpose: This study aimed to identify the predictive value of the low preablation-stimulated thyroglobulin (ps-Tg, <2 ng/ml) for excellent response to radioiodine remnant ablation in differentiated thyroid carcinoma.
Patients And Methods: A total of 398 consecutive patients who underwent total thyroidectomy and radioactive iodine remnant ablation therapy were reviewed retrospectively. Each patient was risk-stratified using the American Joint Cancer Committee and risk staging systems and using response to the initial therapy reclassification system.
The increasing detection of papillary thyroid microcarcinoma (PTMC) has created management dilemmas. To clarify the clinical significance of postsurgery stimulated thyroglobulin (ps-Tg) in PTMC who undergo thyroidectomy and radioactive iodine (RAI), we retrospectively reviewed the 358 PTMC patients who were treated with RAI and followed up in our hospital. Those with an excessive anti-Tg antibody, ultrasound-detected residual were excluded, thereby resulting in the inclusion of 280 cases.

Thyroid cancer is a common malignancy of the endocrine system. Although radioiodine (131)I treatment on differentiated thyroid cancer is widely used, many patients still fail to benefit from (131)I therapy. Therefore, exploration of novel targeted therapies to suppress tumor growth and improve radioiodine uptake remains necessary.
View Article and Find Full Text PDFPurpose: The aim of this study was to identify molecular markers associated with differentiated thyroid carcinoma (DTC) patients and to determine whether there was a correlation between clinicopathological features or molecular markers and the outcome of radioiodine therapy.
Patients And Methods: We retrospectively reviewed the records of 68 patients with papillary thyroid carcinoma (PTC) and 6 patients with follicular thyroid carcinoma (FTC), who underwent iodine treatment. All patients were divided into a cured group (no evidence for disease) and a noncured group (presence of residual or recurrent disease).
The purpose of this study was to investigate and compare the feasibility of rat sodium iodide symporter (rNIS) and human sodium iodide symporter (hNIS) as reporter genes for noninvasive monitoring of rat bone marrow mesenchymal stem cells (rBMSCs) transplanted into infarcted rat myocardium. rBMSCs were isolated from rat bone marrow. Adenovirus (Ad) was reconstructed to contain rNIS-enhanced green fluorescent protein (eGFP) or hNIS-eGFP.
