Abstract Introduction There is much literature about the role of 2-[ 18 F]FDG PET/CT in patients with breast cancer (BC). However, there exists no international guideline involvement nuclear medicine societies this subject. Purpose To provide an organized, international, state-of-the-art, and multidisciplinary guideline, led by experts two (EANM SNMMI) representation important field BC (ACR, ESSO, ESTRO, EUSOBI/ESR, EUSOMA). Methods Literature review expert discussion were performed aim...

Background: Well-differentiated thyroid cancer (WDTC) is the most common endocrine neoplasia, and its incidence rising. Studies have reported an increased risk of second primary (SPC) in WDTC survivors, but relationship with radioiodine treatment (RAIT) other factors remains controversial. This study evaluated whether RAIT independent factor for SPC patients. Methods: was a retrospective single-center study. A total 2031 patients diagnosed between 1998 2009, treated followed at authors'...

The estrogen receptor (ER), a steroid hormone important in female physiology, is significant contributor to breast carcinogenesis and progression and, as such, an therapeutic target. Approximately 70% of cancers will express ER at presentation, the determination expression by tissue assay, usually immunohistochemistry, part standard care for newly diagnosed cancer. guiding approach treatment, especially with increase relevant systemic therapies. ER-targeting imaging agent...

Abstract The objective is to assess the performance of seven semiautomatic and two fully automatic segmentation methods on [ 18 F]FDG PET/CT lymphoma images evaluate their influence tumor quantification. All lesions identified in 65 whole-body staging were segmented by experienced observers using manual methods. Semiautomatic absolute relative thresholds, k -means Bayesian clustering, a self-adaptive configuration (SAC) was applied. Three state-of-the-art deep learning–based segmentations 3D...

Prostate-specific membrane antigen (PSMA) is specific for prostate cancer cells; nevertheless when finding uptake in abnormal locations metastases, it important to consider other hypothesis, including second cancers. There are several papers about PSMA expression many different types of cancer, but few reported gastrointestinal stromal tumors (GIST). In this case, we documented the GIST lesion not only by PET/CT also gastroscopy and histology. Additionally, immunochemistry was performed,...
