Lymph node yield in the initial central neck dissection (CND) associated with the risk of recurrence in papillary thyroid cancer: A reoperative CND cohort study.

Background: To evaluate the relationship between lymph node yield (LNY) from the initial central neck dissection (CND) and the risk of recurrence in patients undergoing reoperative CND for papillary thyroid cancer (PTC).

Method: We reviewed clinical data from all patients with pathologically proven PTC who underwent central neck and/or lateral neck dissection reoperations at Nanfang Hospital between 2012 and 2020. Patient demographics, tumor characteristics, clinical data and follow-up information were obtained.

The prognostic value of end-of-treatment FDG-PET/CT in diffuse large B cell lymphoma: comparison of visual Deauville criteria and a lesion-to-liver SUV ratio-based evaluation system.

Purpose: The aim of this study was to determine a better criterion for end-of-treatment PET (EoT-PET) assessment and prognostic evaluation of patients with diffuse large B cell lymphoma (DLBCL).

Method: EoT-PET scans were assessed using the visual Deauville 5-point scale (5PS) and LLR, the maximum standard uptake value ratio between the lesion and the liver. The cutoff value of LLR was obtained by receiver operator characteristic curve analysis.

The Clinical Accuracy and Risk Stratification in End of Therapy F-FDG PET/CT in Burkitt Lymphoma.

Purpose: Burkitt lymphoma (BL) is an invasive lymphoma subtype with FDG avid at F-FDG PET/CT, but there is currently no validated criterion in treatment evaluation and prognosis prediction. The aim of this study was to analyze the clinical accuracy of F-FDG PET/CT in Burkitt lymphoma in end of therapy PET/CT (EOT-PET) to assess the treatment response in BL and conduct a survival analysis with different Deauville 5-point score (DS) cutoff values.

Materials And Methods: A total of 189 patients were retrospectively included: 97 underwent baseline PET/CT and all underwent EOT-PET.

Predictors for reactive thymic hyperplasia and its prognostic value in children and adolescents with lymphoma.

Background: Reactive thymic hyperplasia (RTH) is seen in children and adolescents receiving chemotherapy for various malignancies. However, it is not clear why this occurs only in some patients. The aim of this study was to identify the predictors for RTH in children and adolescents receiving chemotherapy for lymphoma and to determine the effect of RTH on prognosis.

Cervical lymph node hyperplasia on [(18)F]-fluorodeoxyglucose positron emission tomography/computed tomography scan after treatment of children and adolescents with malignant lymphoma.

Purpose: To define imaging manifestations and clinical prognosis of cervical lymph node hyperplasia using [(18)F]-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) scanning after treatment of children and adolescents with malignant lymphoma.

Methods: Children and adolescent patients with malignant lymphoma who had high FDG uptake in their cervical lymph nodes via PET/CT after treatment, which was not due to tumor recurrence or residue, were retrospectively analyzed.

Results: Twenty-seven patients with a median age of 12 years were included; 11 had Hodgkin's disease and 16 had non-Hodgkin's lymphoma.
