The DASciS Software for BSI Calculation as a Valuable Prognostic Tool in mCRPC Treated with 223RaCl2: A Multicenter Italian Study.

Background/aim: Radium-223 dichloride (RaCl) represents a therapeutic option for metastatic castration-resistant prostate cancer (mCRPC) patients dealing with symptomatic bone metastases. The identification of baseline variables potentially affecting the life-prolonging role of RaCl is still ongoing. Bone scan index (BSI) defines the total load of bone metastatic disease detected on a bone scan (BS) and is expressed as a percentage value of the whole bone mass.

Volumetric Modulated Arc Radiotherapy Efficacy After Double Recurrences of Cardiac Sarcoma.

Background: Volumetric Modulated Arc Therapy (VMAT) has recently become a pivotal treatment of oncological diseases due to the high-precise delineation of target volume contours with sparing organs at risk. This procedure requires a high level of experience and precision and is achievable only with advanced diagnostic support. Magnetic Resonance (MRI) and multimodality imaging, such as 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT), are fundamental in implementing radiotherapy guidance.

PET Criteria by Cancer Type from Imaging Interpretation to Treatment Response Assessment: Beyond FDG PET Score.

Background: in recent years, the role of positron emission tomography (PET) and PET/computed tomography (PET/CT) has emerged as a reliable diagnostic tool in a wide variety of pathological conditions. This review aims to collect and review PET criteria developed for interpretation and treatment response assessment in cases of non-[F]fluorodeoxyglucose ([F]FDG) imaging in oncology.

Methods: A wide literature search of the PubMed/MEDLINE, Scopus and Google Scholar databases was made to find relevant published articles about non-[F]FDG PET response criteria.

Lympho-SPECT/CT as a Key Tool in the Management of a Patient with Chylous Ascites.

Chylous ascites is a rare form of ascites usually associated with cirrhosis, abdominal malignancies, surgeries or infections. We presented a case of chylous ascites after robotic laparoscopic prostatectomy (PLDN-RALP), in which the correct diagnosis was achieved by SPECT/CT lymphoscintigraphy. A 72-year-old male developed chylous ascites after surgery and underwent lymphoscintigraphy with radiolabeled albumin nanocolloids for the supplementary study of the lymph flow and to detect a possible site of leakage.

[F]FDG PET/CT in head and neck squamous cell carcinoma: a head-to-head between visual point-scales and the added value of multi-modality imaging.

Background: Head and neck squamous cell carcinoma (HNSCC) represents the 6th leading cancer worldwide. In most cases, patients present a locally advanced disease at diagnosis and non-surgical curative treatment is considered the standard of care. Nowadays, [F]FDG PET/CT is a validated tool in post-treatment evaluation, with a high level of evidence.
