OBJECTIVES: The objective of this study is to evaluate long-term outcomes, specifically patterns of tumor recurrence, in patients with adult medulloblastoma treated with radiotherapy. METHODS: We recorded outcomes of 28 (median age, 25 y) patients 18 years old or above with M0 to M3 medulloblastoma treated between 1971 and 2012. Among them, 61% had standard-risk disease. All received craniospinal irradiation with a posterior fossa boost. Median dose to the craniospinal axis was 36 Gy...

The metastasis of tumour cells to bone can lead to osteolytic and osteosclerotic lesions, which cause severe, highly-localized bone destruction and abnormal bone apposition, respectively. Accurate quantification of lesion progression is critical to understand underlying mechanisms and assess treatment efficacy; however, standard structural parameters may be insensitive to local changes. We developed methods to quantify osteolytic and osteosclerotic lesions using micro-computed tomography (micro-CT) within in vivo mouse datasets...

BACKGROUND AND OBJECTIVES: With increasing life expectancy of patients with bone metastasis, durable surgical stabilization of bone metastasis is necessary. Local recurrence (LR) can compromise surgical stabilization and necessitate retreatment. We analyzed LR rate and factors associated with LR in patients undergoing surgery for bone metastasis. METHODS: Patients (n = 301) who underwent surgery for bone metastasis to the extremities were reviewed. Possible factors that might be associated with LR were investigated...

MicroRNAs (miRs) have a critical role in the development and malignant progression of osteosarcoma (OS), but the underlying mechanisms have largely remained elusive. The present study aimed to explore the regulatory role of miR-138 in OS growth and metastasis and investigated the associated mechanisms. Reverse-transcription quantitative polymerase chain reaction and western blot analysis were performed to examine the miR-138 and protein expression levels in OS and normal bone tissues and cell lines. An MTT assay and a Transwell assay were used to assess cell proliferation and invasion...

BACKGROUND: Malignant fibrous histiocytoma is a sarcoma of uncertain origin that can be found both in soft tissues and in bones. It is currently called undifferentiated pleomorphic sarcoma not otherwise specified and it represents a final common pathway in several tumors that are subject to the progress of dedifferentiation. Local recurrence of the tumor in the same location where it was originated occurs in 20-30% of the total number of soft tissue sarcomas. It is less frequent in limbs and more likely to recur in retroperitoneal sarcomas and in head and neck...

Osteolytic bone resorption is the primary cause of pain and suffering (e.g., pathological bone fracture) in women with metastatic breast cancer. The current standard of care for patients with bone metastasis for reducing the incidence of skeletal complications includes bisphosphonates and a humanized antibody (denosumab). However, a subset of patients on these therapies still develops new bone metastasis or experience adverse effects. Moreover, some bisphosphonates have poor oral bioavailability. Therefore, orally-bioavailable and non-toxic inhibitors of breast cancer-induced osteolytic bone resorption are still clinically desirable...

This study investigated the regulatory effect of microRNA-203 on bone metastasis of non-small cell lung cancer (NSCLC). Quantitative real-time PCR was used to examine microRNA-203 in tissue specimens of bone metastasis of patients with NSCLC. In bone metastasis of patients with NSCLC, microRNA-203 expression was decreased, compared with control group. We also surveyed overall survival (OS) and disease-free survival (DFS), microRNA-203 high expression in bone metastasis of patients with NSCLC was higher than in those with microRNA-203 low expression...

BACKGROUND: Adjuvant use of bisphosphonates can reduce the incidence of bone metastases in early breast cancer. Recurrence and survival seem to be improved only in postmenopausal patients, but the underlying mechanisms remain unclear. We investigated whether MAF amplification (a biomarker for bone metastasis) in primary tumours could predict the treatment outcomes of adjuvant zoledronic acid. METHODS: The study population included patients enrolled in the international, open-label, randomised, controlled, phase 3 AZURE trial at eligible UK sites who had stage II or III breast cancer and who gave consent for use of their primary tumour samples...

Sorafenib is widely used for unresectable and metastatic hepatocellular carcinomas. Radiation recall dermatitis (RRD) is an acute inflammatory reaction confined to previously irradiated skin that occurs after the administration of certain drugs. RRD after sorafenib treatment is rare; five cases have been reported thus far. We describe a 44-year-old man irradiated for chest wall bone metastasis from hepatocellular carcinoma. Eight days after radiotherapy completion, systemic therapy for metastatic hepatocellular carcinoma was initiated with sorafenib treatment...

Although extrahepatic metastases from hepatocellular carcinoma (HCC) are present in only 5-15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma...

Prostate cancer (PCa) is the second most diagnosed cancer in men. Early diagnosis and right management of PCa is critical to reducing deaths; the life expectancy is the main factors to be considered in the management of PCa. Among patients who die from PCa, the incidence of skeletal involvement appears to be >85%. Bone scan (BS) is the most common method for monitoring bone metastases in patients with PCa. The extent of bone metastasis was also associated with patient survival until now there is no clinically useful technique for measuring bone tumors and includes this information in the risk assessment...

Recently, there have been considerable advancements in cancer therapies thereby prolonging the life of cancer survivors. However, these recent advancements present new challenges in the management of bone disease in cancer survivors. Bone acts as a fertile soil for cancer seeding and bone health is often compromised because of increased inflammatory cytokines in cancer, direct cancer metastasis and toxic effects of anti-cancer therapies. This effect is more pronounced in elderly population who already have compromised bone mineral density leading to increased skeletal related events and bone pain...

PURPOSE: Sensitive visualization of recurrent prostate cancer foci is a challenge in patients with early biochemical recurrence (EBR). The recently established (68)Ga-PSMA-11 PET/CT has significantly improved the detection rate with published values of up to 55% for patients with a serum PSA concentration between 0.2-0.5 ng/mL. The increased soft tissue contrast in the pelvis using simultaneous (68)Ga-PSMA-11 PET/MRI might further improve the detection rate in patients with EBR and low PSA values over PET/CT...

BACKGROUND: Metastases from primary breast cancers can involve single or multiple organs at metastatic disease diagnosis. Molecular risk factors for particular patterns of metastastic spread in a clinical population are limited. METHODS: A case-control design including 1357 primary breast cancers was used to study three distinct clinical patterns of metastasis, which occur within the first six months of metastatic disease: bone and visceral metasynchronous spread, bone-only, and visceral-only metastasis...

Tumors of the prostate or breast are particularly likely to metastasize to the bone, and early diagnosis of metastatic bone tumors is important for designing an effective treatment strategy. Imaging modalities for the detection of bone metastasis are limited, and radiation-based techniques are commonly used. Here, we investigated the efficacy of selective near-infrared (NIR) fluorescence detection of metastatic bone tumors and its role in the detection of bone metastasis in prostate and breast cancer cell lines and in a xenograft mouse model...

A clinical diagnosis of metastatic bone tumors is usually based on radiological findings without bone biopsy. Plasmacytoma can present as a single osteolytic lesion as described in this case. Early bone biopsy should be considered in unusual clinical settings for a differential diagnosis of primary bone tumors.

A 68-year-old woman with a recent history of blurring in the left eye had undergone mastectomy for breast cancer twenty years ago. A series of bone metastases started five years after her diagnosis. Examination of the optic nerve head of the left eye revealed an isolated epipapillary mass. Indocyanine green angiography displayed vessels within the mass, and fluorescein angiography demonstrated hyperfluorescence of the mass from vascular leakage plus lobular spots of blocked fluorescence. B-scan ultrasound revealed a hyperechoic elevated nodular mass on the optic disc...
