Late Ga PSMA-positive Pancreatic Metastasis From Renal Cell Carcinoma in a Patient with Metastatic Prostate Cancer: A Mission Impossible.

We present the case of a patient with newly diagnosed high-risk prostate cancer. The patient underwent nephrectomy for renal cell carcinoma (RCC) in 2009. The prostate-specific membrane antigen (PSMA) scan revealed a primary tumor with seminal vessel involvement, PSMA-positive regional lymph nodes, several nodular lung lesions with mild PSMA uptake, PSMA-positive mediastinal lymph nodes, and a PSMA-positive mass in the pancreatic head.

FAST: a randomised phase II study of zolbetuximab (IMAB362) plus EOX versus EOX alone for first-line treatment of advanced CLDN18.2-positive gastric and gastro-oesophageal adenocarcinoma.

Background: Claudin 18.2 (CLDN18.2) is contained within normal gastric mucosa epithelial tight junctions; upon malignant transformation, CLDN18.

Effect of the cytochrome P450 2C19 inhibitor omeprazole on the pharmacokinetics and safety profile of bortezomib in patients with advanced solid tumours, non-Hodgkin's lymphoma or multiple myeloma.

Background And Objective: Bortezomib, an antineoplastic for the treatment of relapsed multiple myeloma and mantle cell lymphoma, undergoes metabolism through oxidative deboronation by cytochrome P450 (CYP) enzymes, primarily CYP3A4 and CYP2C19. Omeprazole, a proton-pump inhibitor, is primarily metabolized by and demonstrates high affinity for CYP2C19. This study investigated whether coadministration of omeprazole affected the pharmacokinetics, pharmacodynamics and safety profile of bortezomib in patients with advanced cancer.

Current diagnostic approaches in tumor-induced bone disease.

Purpose: To assess the role of the current imaging methods in the diagnosis, staging and post-therapeutic monitoring of cancer-induced bone disease.

Patients And Methods: 183 cancer patients underwent baseline whole body bone scintigraphy (WBBS) with 555- 740 MBq (99m)Tc-MDP. Computed tomography (CT) was carried out in 43 patients, and magnetic resonance imaging (MRI) in 26 patients with abnormal uptake on the bone scan in order to differentiate metastatic or degenerative skeletal lesions with similar scintigraphic appearance.

Nuclear medicine approaches in the monitoring of thyroid cancer patients.

Purpose: To evaluate the role of some nuclear medicine approaches such as (99m)Tc-MIBI scan and (131)I whole-body scintigraphy (WBS) in the monitoring of patients with differentiated thyroid cancer (DTC).

Patients And Methods: 95 patients (69F/26M) aged 17-74 years (mean 44.2) with DTC (56 cases with papillary, 20 with follicular and 19 with papillary-follicular carcinoma) were assessed.
