Various radionuclides have been used for pain therapy. Recently, an α-emitter has been shown to improve overall survival of patients with bone metastases from castration-resistant prostate cancer and was approved as a therapeutic agent. The aim of this article is to provide an overview regarding sta...

The possible different roles of denosumab in prevention and cure breast cancer bone metastases: A 'hypothesis-generator' study from clinical practice.

The most frequent site of recurrence in breast cancer (BC) is the bone, particularly in patients with 'luminal-like' disease. Denosumab has been shown to prevent aromatase inhibitors (AIs) induced bone resorption in postmenopausal early BC patients and reduce skeletal-related events (SREs) in bone metastatic breast cancer (BMBC). A 'real life' analysis of 90 BMBC patients treated with denosumab was performed. Eighty-six patients (95.6%) had 'luminal-like' disease, 72 (80%) had bone metastases at the time of...

Palliative radiation therapy (RT) for prostate cancer patients with bone metastases at diagnosis: A hospital-based analysis of patterns of care, RT fractionation scheme, and overall survival.

Prostate cancer (PCa) is one of the most common malignancies associated with bone metastases, and palliative radiation therapy (RT) is an effective treatment option. A total of 2641 patients were identified with PCa and bone metastases at diagnosis from 2010 to 2014 in the NCDB. Fractionation scheme was designated as short course ([SC-RT]: 8 Gy in 1 fraction and 20 Gy in 5 fractions) vs long course ([LC-RT]: 30 Gy in 10 fractions and 37.5 Gy in 15 fractions). Patient characteristics were correlated with...

Prevalence of bone pain decreases as lymph node stage increases in nonsmall cell lung cancer patients.

According to lung cancer guidelines, positron emission tomography scan is recommended for initial evaluation of bone metastasis. However, guidelines differ in their recommendations for when it should be used. We investigated the appropriate use of bone imaging in nonsmall cell lung cancer (NSCLC) patients. One hundred seventy-seven consecutive NSCLC patients who had distant metastases at presentation and were admitted between January 2012 and April 2016 were retrospectively reviewed. Among patients with bon...

Mechanistic modelling of Radium-223 treatment of bone metastases.

Despite the effectiveness of RaCl for treating patients with symptomatic bone metastatic disease, its mechanisms of action are still unclear. Even established dosimetric approaches differ considerably in their conclusions. In silico tumour models bring a new perspective to this as they can quantitatively simulate the interaction of α-particles with the target(s). Here, we investigated three different mathematical models of tumour growth that take into account the radiation effect of Radium-223 treatments a...

A Population-Based Study Of Palliative Radiotherapy For Bone Metastases In Patients Dying Of Prostate Cancer.

Bone Metastases - Pathophysiology, Diagnostic Testing and Therapy (Part 2).

The second part of this review deals with the several options for the surgical therapy of bone metastases according to their anatomical site and the patient's individual prognosis. Although metastases to the bone - with few exceptions - are normally given palliative therapy, patients nowadays reach survival times of several months to years, depending on the underlying tumour entity. Scoring systems are suitable to estimate the patient's prognosis and fracture risk. The indication for operation has to be ada...

Management of Brain Metastases in the New Era of Checkpoint Inhibition.

Brain metastasis is a common complication of advanced malignancies, especially, lung cancer, breast cancer, renal cell carcinoma, and melanoma. Traditionally surgery, when indicated, and radiation therapy, either as whole-brain radiation therapy or stereotactic radiosurgery, constituted the major treatment options for brain metastases. Until recently, most of the systemic chemotherapy agents had limited activity for brain metastases. However, with the advent of small molecule tyrosine kinase inhibitors and ...

Radium-223 in combination with paclitaxel in cancer patients with bone metastases: safety results from an open-label, multicenter phase Ib study.

Concomitant treatment with radium-223 and paclitaxel is a potential option for cancer patients with bone metastases; however, myelosuppression risk during coadministration is unknown. This phase Ib study in cancer patients with bone metastases evaluated the safety of radium-223 and paclitaxel.

Stereotactic Body Radiation Therapy in Non-Surgical Patients with Metastatic Spinal Disease and Epidural Compression: A Retrospective Review.

In the setting of spinal metastases with epidural cord compression, radiosurgery is often only considered when there is sufficient separation between the epidural disease and the spinal cord. However, in patients who are non-surgical candidates or those who prefer non-operative management, there may be a benefit from stereotactic body radiation therapy (SBRT) even when the epidural target is closer than the traditionally referenced 3 mm distance from the spinal cord. The purpose of this retrospective study ...

Neurocognitive evaluation of brain metastases patients treated with post-resection stereotactic radiosurgery: a prospective single arm clinical trial.

Post-operative radiation therapy for brain metastases (BM) has become standard treatment. Concerns regarding the deleterious cognitive effects of Whole Brain Radiation Therapy spurred a trend to use focal therapies such as stereotactic radiosurgery (SRS). The purpose of this study was to prospectively evaluate the neuropsychological effects following post-resection SRS treatment since limited data exist in this context.

Medication-related osteonecrosis of the jaw: Prevention, diagnosis and management in patients with cancer and bone metastases.

Medication-related osteonecrosis of the jaw (MRONJ) is primarily an adverse side effect of denosumab or bisphosphonates (particularly when used at high doses to prevent skeletal-related events [SREs] in patients with cancer and bone metastases) or possibly anti-angiogenic cancer treatment. While the implementation of preventive measures over recent years has reduced the risk of MRONJ in patients with bone metastases due to cancer, it is imperative to balance the risk of MRONJ against the beneficial effects ...

Practical Consideration for Integrating PET/CT in Radiation Therapy Planning for Patient Care.

Over the past 20 years, PET/CT has had many technological and developmental advancements for patient care. PET/CT has evolved from solely used as a diagnosis and staging tool to now having an impact on treating cancer through a collaboration with radiation oncology. There are multiple considerations when integrating PET/CT into radiation therapy planning such as PET/CT center needs, the types of scans to offer, workflow considerations between the two centers, PET/CT center growth and demand on schedules, an...

Earlier Phases of Bone Scintigraphy Can Better Delineate the Extent of Soft Tissue Involvement of Bone Metastasis.

Three-phase bone scintigraphy is sometimes of great value in the detection of uncharacteristic metastases and assists the management of patients in terms of primary focus detection. While evaluating the skeletal system with whole-body bone scintigraphy, other system pathologies may also be detected incidentally. In this case, we present the extraordinary findings on the 3-phase MDP bone scintigraphy and F-FDG PET/CT imaging of the complicated bone metastases in a patient with thyroid carcinoma.
