Focal incidental uptake, with or without CT abnormalities, is a common finding on FDG PET/CT and evidence based management for this type of uptake is lacking. This article reviews the evidence on focal incidental uptake including the incidence of malignancy, differential diagnosis and imaging criteria which can be used to further characterise it. The article focusses on PET rather than CT criteria. The strength of the evidence base is highly variable ranging from systematic reviews and meta-analyses to a virtual absence of evidence...

OBJECTIVES: To establish a new three-dimensional quantitative evaluation method for bone metastasis, we applied bone single photon emission tomography with computed tomography (SPECT/CT). The total bone uptake (TBU), which measures active bone metastatic burden, was calculated as the sum of [mean uptake obtained as standardized uptake value (SUV) above a cut-off level] × (the volume of the lesion) in the trunk using bone SPECT/CT. We studied the threshold value and utility of TBU in prostate cancer patients treated with radium-223 (Ra-223) therapy...

In thyroid cancer patients with renal impairment or other complicating factors, it is important to maximize I-131 therapy efficacy while minimizing bone marrow and lung damage. We developed a web-based calculator based on a modified Benua and Leeper method to calculate the maximum I-131 dose to reduce the risk of these toxicities, based on the effective renal clearance of I-123 as measured from two whole-body I-123 scans, performed at 0 and 24 h post-administration.

F-18 NaF PET/CT evaluation has gained importance in recent years. Achievements from F-18 NaF PET/CT are: higher sensitivity of positron imaging, higher target background ratio with higher tracer accumulation in bone hydroxyapatite and higher specificity through CT correlation. These properties have also given directions to new research fields based on imaging microcalcifications, very recently. A limited number of cases have reported the F-18 NaF uptake in macrocalcified soft tissue metastases. Although the presence of microcalcification was not proved; accumulation of F-18 NaF in the metastatic brain lesion with no visible calcification on the CT, in a patient with ductal breast carcinoma has also been reported...

A patient with a history of adenoid cystic carcinoma of the nasal cavity presented himself with bone pain and an elevated PSA level. On suspicion of metastatic prostate cancer a 68Ga-PSMA PET-CT was performed. The PET-CT showed numerous lung and non-sclerotic bone metastasis. Biopsy of a bone metastasis was performed and pathology showed adenoid cystic carcinoma instead of prostate cancer. Immunohistochemical PSMA staining of the primary tumour showed intense PSMA expression in adenoid cystic carcinoma tumour cells...

Adenoviral (Ad) vector vaccines represent one of the most promising modern vaccine platforms, and Ad vector vaccines are currently being investigated in human clinical trials for infectious disease and cancer. Our studies have shown that specific targeting of adenovirus to dendritic cells dramatically enhanced vaccine efficacy. However, this was achieved using a molecular adapter, thereby necessitating a two component vector approach. To address the mandates of clinical translation of our strategy, we here sought to accomplish the goal of DC targeting with a single-component adenovirus vector approach...

Medication-related osteonecrosis of the jaw (MRONJ) has most commonly been associated with bisphosphonates. The routine uses of these drugs are now well established predominantly in metastatic cancer with bone involvement, multiple myeloma, hypercalcaemia, osteoporosis and Paget's disease. Recently, however, the use of bisphosphonates in early breast cancer has shown a reduction in breast cancer recurrence and breast cancer deaths. This new indication for their use approximates to a further 20,000 women per year in the UK being prescribed bisphosphonates...

PSMA PET/CT has a high diagnostic accuracy for lesion detection in metastatic prostate cancer (MPC), including bone metastases. Novel therapeutic approaches require valid biomarkers for standardized disease staging, progression and therapy response. Here, we introduce EBONI (Evaluation of Bone Involvement), a software to automatically quantify bone metastasis load in PSMA PET/CT. Lesion quantity, mean and maximum lesional standardized uptake value (SUV), Z-Score and percentage of affected bone volume are determined...

Salidroside, an active constituent from the root of Rhodiola rosea L., has multiple pharmacological effects, such as anti-cancer, anti-inflammatory and anti-oxidative properties, etc. However, its protective effect on bone tissue via regulating calcium homeostasis is yet to be determined. This study was performed to investigate if salidroside could protect against bone injuries induced by estrogen deficiency or hyperglycemia through modulating calcium homeostasis. Ovariectomized (OVX) mice and diabetic mice were treated with salidroside (20mg/kg) for 6 weeks...

The tumor necrosis factor (TNF) receptor RANK (TNFRSF11A) and its ligand RANKL (TNFSF11) regulate osteoclast development and bone metabolism. They also control stem cell expansion and proliferation of mammary epithelial cells via the sex hormone progesterone. As such, RANKL and RANK have been implicated in the onset of hormone-induced breast cancer. Recently, RANK/RANKL were identified as crucial regulators for BRCA1 mutation-driven breast cancer. Current prevention strategies for BRCA1 mutation carriers are associated with wide-ranging risks; therefore, the search for alternative, non-invasive strategies is of paramount importance...

Multiple myeloma is a hematological malignancy, which sometimes creates difficulties in diagnosis, based on the presence of monoclonal protein in serum/urine and plasmocyte infiltration in the bone marrow, and on the other hand, synchronous cancers are also a diagnostic challenge. We present a case report of a patient with concurrent breast cancer and multiple myeloma. A 68-year-old woman was admitted to the hospital with diagnosis of left breast cancer in first stage of the disease. In the past, she had had several episodes of thrombocytopenia, leucocytosis, and mild anaemia, which were followed by hematologist in outpatient setting...

Androgen deprivation therapy (ADT) is the mainstay of treatment of patients with relapsed or metastatic hormone-sensitive prostatic carcinoma. The dramatic reduction of serum testosterone levels induced by ADT produces multiple side effects as vasomotor flushing, sexual dysfunction, fatigue, impairment of cognitive function, reduced quality of sleep, gynecomastia and anemia, that are able to decrease health-related quality of life (QoL). In addition, hormonal therapy can interfere with bone metabolism and induce metabolic and cardiovascular complications...

The traditional therapy of cancer has systemic side effects, and many cancers, such as human breast cancer and lung cancer easily metastasize to bones, leading to the formation of secondary tumours. This study was aimed at enhancing the anti-tumour effect of curcumin (CUR) and preventing tumour spread to the bone. A novel multifunctional redox-responsive and CD44 receptor targeting polymer-drug, poly alendronate-hyaluronan-S-S-curcumin copolymer (ALN-oHA-S-S-CUR) based CUR and alendronate (ALN) were synthesized successfully with the disulphide bond linker...
