Clinical Nuclear Medicine Center, Imaging Clinical Medical Center, Institute of Nuclear Medicine, Institute of Clinical Mass Spectrometry Applied Research Center, Department of Nuclear Medicine, Shanghai Tenth People's Hospital, School of Medicine, Tongji University, Shanghai, 200072, China.

Background: Multiple high doses of I therapy in patients with differentiated thyroid cancer (DTC) might disrupt the balance of gut microbiota and metabolites. This study aimed to investigate the alterations of intestinal bacteria and metabolism over two courses of I therapy, explore the interactions, and construct diagnostic models reflecting enteric microecology based on I therapy.

Methods: A total of 81 patients were recruited for the first I therapy (I-1st), among whom 16 received a second course (I-2nd) after half a year.

The leading cause of gastritis and its complications is Radioactive iodine (I) accumulates significantly in the stomach after consumption. On this basis, we decided to determine whether different doses of I in the stomach would be effective in eradicating the infection. All patients with hyperthyroidism or differentiated thyroid carcinoma who were referred for I treatment were invited to the study.

Article Synopsis
  • This study explores the relationship between preoperative gastric emptying scintigraphy (GES) and the success of gastric peroral endoscopic myotomy (G-POEM) in patients with gastroparesis.
  • It found that only the proximal to distal count ratio (PDCR) at 0 hours is linked to clinical success, with higher values indicating better outcomes.
  • Results suggest that patients with a PDCR0 greater than 5.25 have a significantly higher chance of long-term success after G-POEM, highlighting its importance in assessing candidates for the procedure.

Disrupted gut microecology after high-dose I therapy and radioprotective effects of arachidonic acid supplementation.

Eur J Nucl Med Mol Imaging

July 2024

Clinical Nuclear Medicine Center, Imaging Clinical Medical Center, Institute of Nuclear Medicine, Department of Nuclear Medicine, Shanghai Tenth People's Hospital, School of Medicine, Tongji University, Shanghai, 200072, China.

Background: Despite the potential radiotoxicity in differentiated thyroid cancer (DTC) patients with high-dose I therapy, the alterations and regulatory mechanisms dependent on intestinal microecology remain poorly understood. We aimed to identify the characteristics of the gut microbiota and metabolites in DTC patients suffering from high-dose I therapy and explore the radioprotective mechanisms underlying arachidonic acid (ARA) treatment.

Methods: A total of 102 patients with DTC were recruited, with fecal samples collected before and after I therapy for microbiome and untargeted and targeted metabolomic analyses.

A 76-year-old man with castration-resistant prostate cancer underwent 68 Ga-prostate-specific membrane antigen (PSMA) PET/CT for restaging. A large PSMA-avid tumor with invasion to adjacent organs was noted causing gross hematuria and symptomatic anemia. Two cycles of 177 Lu-PSMA were administered, and the patient showed significant reduction of hematuria as well as declining in PSA levels.

May 2024

Department of Nuclear Medicine, Taleghani Educational Hospital, School of Medicine, Shahid, Beheshti University of Medical Sciences, Tehran, Iran.

In this note, we aim to present a patient with a known case of prostate cancer with widespread metastasis to the skeleton and liver who has undergone several cycles of chemoradiotherapy. The patient received 2 doses of 177 Lu-prostate-specific membrane antigen therapy, in which several zones of uptake were detected on the thoracic wall compatible with cutaneous metastatic lesions of prostate cancer.

Hodgkin Lymphoma (HL) is characterized by an inflammatory background in which the reactive myeloid cells may exert an immune-suppressive effect related to the progression of the disease. Immunoglobulin M is the first antibody isotype produced during an immune response, which also plays an immunoregulatory role. Therefore, we investigated if, as a surrogate of defective B cell function, it could have any clinical impact on prognosis.

Clinical Nuclear Medicine Center, Imaging Clinical Medical Center, Institute of Nuclear Medicine, Department of Nuclear Medicine, Shanghai Tenth People's Hospital, School of Medicine, Tongji University, Shanghai, 200072, China.

Article Synopsis
  • This study assessed body composition changes in differentiated thyroid cancer (DTC) patients who underwent thyroidectomy, radioactive iodine therapy (RAI), and short-term levothyroxine (LT4) supplementation.
  • Results showed a decrease in fat mass and an increase in bone mineral content (BMC) and bone mineral density (BMD) across various body regions shortly after treatment.
  • Additionally, correlations were found between changes in fat distribution and blood cholesterol levels, along with positive associations between BMC/BMD changes and calcitonin levels.

Axicabtagene ciloleucel (axi-cel) demonstrated superior efficacy compared to standard of care as second-line therapy in patients with high-risk relapsed/refractory (R/R) large B cell lymphoma (LBCL) considered eligible for autologous stem cell transplantation (ASCT); however, in clinical practice, roughly half of patients with R/R LBCL are deemed unsuitable candidates for ASCT. The efficacy of axi-cel remains to be ascertained in transplant-ineligible patients. ALYCANTE, an open-label, phase 2 study, evaluated axi-cel as a second-line therapy in 62 patients with R/R LBCL who were considered ineligible for ASCT.

Anlotinib in Locally Advanced or Metastatic Radioiodine-Refractory Differentiated Thyroid Carcinoma: A Randomized, Double-Blind, Multicenter Phase II Trial.

Clin Cancer Res

October 2023

Department of Thyroid and Neck Oncology, Tianjin Medical University Cancer Institute and Hospital, National Clinical Research Center for Cancer; Key Laboratory of Cancer Prevention and Therapy, Tianjin; Tianjin's Clinical Research Center for Cancer, Tianjin, China.

Purpose: Alhough antiangiogenic agents are the bedrock of treatment for radioiodine-refractory differentiated thyroid carcinoma (RAIR-DTC), novel antiangiogenic agents with optimized features like greater target-binding affinities and more favorable pharmacokinetics profile are needed. This phase II randomized, double-blind, placebo-controlled trial investigated the efficacy and safety of anlotinib, a multikinase inhibitor, for RAIR-DTC.

Patients And Methods: Patients (ages between 18 and 70 years) with pathologically confirmed locally advanced or metastatic RAIR-DTC were enrolled and randomly received 12 mg anlotinib once daily or placebo on day 1 to 14 every 3 weeks.

Article Synopsis
  • Dipyridamole is commonly used for thallium-201 imaging to detect coronary arterial disease, and while it can cause mild noncardiac side effects like chest pain and headaches, these can usually be managed with aminophylline.
  • A case of a 45-year-old woman showed high-grade AV block and sinus arrest shortly after dipyridamole infusion, despite no signs of ischemia on the thallium scan and a normal baseline ECG.
  • The occurrence of AV block in this case raises concerns about bradyarrhythmias as a potential complication of dipyridamole, especially in those with existing conduction issues, and highlights the need for further investigation into the mechanisms behind such arrhythmias.

Department of Physical Therapy, Speech, and Occupational Therapy, Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP), São Paulo 05360-160, Brazil.

The aim of this study was to characterize the oral discourse of CBS patients and to verify whether measures obtained during a semi-spontaneous speech production could differentiate CBS patients from controls. A second goal was to compare the performance of patients with CBS probably due to Alzheimer's disease (CBS-AD) pathology and CBS not related to AD (CBS-non-AD) in the same measures, based on the brain metabolic status (FDG-PET) and in the presence of amyloid deposition (amyloid-PET). Results showed that CBS patients were significantly different from controls in speech rate, lexical level, informativeness, and syntactic complexity.
