Special issue "The advance of solid tumor research in China": 68Ga-PSMA-11 PET/CT for evaluating primary and metastatic lesions in different histological subtypes of renal cell carcinoma.

Int J Cancer 2022 Jun 25. Epub 2022 Jun 25.

Department of Urology, Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, 651 Dongfeng Road East, Guangzhou, People's Republic of China.

Conventional imaging examinations are not sensitive enough for the early detection of recurrent or metastatic lesions in renal cell carcinoma (RCC) patients. We aimed to explore the role of Ga- prostate specific membrane antigen (PSMA)-11 positron emission tomography (PET)/computed tomography (CT) in the detection of primary and metastatic lesions in such patients. We retrospectively analyzed 50 RCC patients who underwent Ga-PSMA-11 PET/CT from November 2017 to December 2020. Read More

Primary Breast Lymphoma Mimicking Metastatic Breast Cancer on 18F-FDG PET-CT.

J Pak Med Assoc 2022 Jun;72(6):1241-1242

Department of Hematology, Kuwait Cancer Control Center, Kuwait.

18F-Fluorodeoxyglucose (FDG) PET-CT is an excellent imaging modality for the evaluation of non-Hodgkin lymphoma (NHL). We report a case of a 45-year-old woman presented with a large right breast mass and suspicious right axillary lymph nodes referred for 18F-FDG PET-CT for staging. 18F-FDG PET-CT images show large hypermetabolic right breast mass infiltrating the skin, multiple hypermetabolic right axillary and subpectoral lymph nodes, along with multiple hypermetabolic bone lesions at axial and appendicular skeleton.

Disseminated Primary Uterine Hepatoid Adenocarcinoma with α-Fetoprotein Production Demonstrated on F-FDG PET/CT.

Diagnostics (Basel) 2022 Jun 12;12(6). Epub 2022 Jun 12.

Department of Oncology, Rigshospitalet, Copenhagen University Hospital, 2100 Copenhagen, Denmark.

We present the F-Fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) findings in a 57-year-old woman with post-menopausal bleeding diagnosed with hepatoid adenocarcinoma (HAC) with a primary tumour in the uterine corpus and a highly elevated level of serum-α-fetoprotein (S-AFP) at presentation. HAC is a variant of adenocarcinoma with hepatic differentiation representing a heterogeneous group of neoplasms that morphologically and immunphenotypically resemble hepatocellular carcinoma (HCC) but are of extrahepatic origin. Microscopically, they are usually poorly differentiated adenocarcinomas proliferating in solid sheets or in a trabecular or cord-like arrangement. Read More

Non-invasively Imageable Tibia-tumor-fragment Implantation Experimental-bone-metastasis Mouse Model of GFP-expressing Prostate Cancer.

In Vivo 2022 Jul-Aug;36(4):1647-1650

AntiCancer Inc, San Diego, CA, U.S.A.;

Background/aim: Although the 5-year survival rate for localized prostate cancer is nearly 100%, prognosis for patients with metastases, of which the bone is the most common site, is poor. In order to evaluate efficacy of treatments against metastatic prostate cancer, experimental tibia-bone-metastasis mouse models of prostate cancer have been previously established. In the present study, we used a novel procedure for establishment of an experimental tibiabone metastasis mouse model, with human PC-3 prostate cancer expressing green fluorescent protein (GFP), that more closely matches prostate cancer growing in the bone.

Minimally Invasive Interventional Procedures for Metastatic Bone Disease: A Comprehensive Review.

Curr Oncol 2022 Jun 7;29(6):4155-4177. Epub 2022 Jun 7.

Diagnostic and Interventional Radiology Unit, IRCCS Istituto Ortopedico Rizzoli, Via Pupilli 1, 40136 Bologna, Italy.

Metastases are the main type of malignancy involving bone, which is the third most frequent site of metastatic carcinoma, after lung and liver. Skeletal-related events such as intractable pain, spinal cord compression, and pathologic fractures pose a serious burden on patients' quality of life. For this reason, mini-invasive treatments for the management of bone metastases were developed with the goal of pain relief and functional status improvement. Read More

Application of a Novel Ga-HER2 Affibody PET/CT Imaging in Breast Cancer Patients.

Front Oncol 2022 30;12:894767. Epub 2022 May 30.

Cyclam with a phosphinate-bis(phosphonate) pendant arm is a bone-targeting carrier of copper radionuclides.

Dalton Trans 2022 Jun 21;51(24):9541-9555. Epub 2022 Jun 21.

Department of Inorganic Chemistry, Faculty of Science, Charles University, Hlavova 8, 128 40 Prague 2, Czech Republic.

Ligands combining a bis(phosphonate) group with a macrocycle function as metal isotope carriers for radionuclide-based imaging and for treating bone metastases associated with several cancers. However, bis(phosphonate) pendant arms often slow down complex formation and decrease radiochemical yields. Nevertheless, their negative effect on complexation rates may be mitigated by using a suitable spacer between bis(phosphonate) and the macrocycle. Read More

Institute of Radiology, Universitätsklinikum Erlangen, Friedrich-Alexander-Universität (FAU) Erlangen-Nürnberg, 91054 Erlangen, Germany.

The growth of primary tumors and metastases is associated with excess body fat. In bone metastasis formation, the bone marrow microenvironment, and particularly adipocytes, play a pivotal role as growth mediators of disseminated tumor cells in the bone marrow. The aim of the present study is to non-invasively characterize the pathophysiologic processes in experimental bone metastasis resulting from accelerated tumor progression within adipocyte-rich bone marrow using multimodal imaging from magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT).
