Radionuclide therapy is widely used as an effective modality in the management of bone pain. The main indication for this treatment is symptomatic bone metastases, confirmed by bone scintigraphy. We present a case of small cell lung cancer (SCLC) stage T4N2M1b, with a good metabolic response to systemic therapy and radiotherapy of the primary tumor and locoregional disease, which became metabol...
PURPOSE Pathologic angiogenesis has been correlated with tumor growth, dissemination, metastasis, and prognosis in solid tumors including breast cancer. Angiogenesis has also been implicated in the pathophysiology of, and shown to be a therapeutic target in tumors arising in the bone marrow. The status of angiogenesis in the bone marrow of breast cancer patients is unknown. The aim of this stud...
Primary bone cancers are extremely rare neoplasms, accounting for fewer than 0.2% of all cancers. The evaluation and treatment of patients with bone cancers requires a multidisciplinary team of physicians, including musculoskeletal, medical, and radiation oncologists, and surgeons and radiologists with demonstrated expertise in the management of these tumors. Long-term surveillance and follow-u...
Breast cancer is the most frequently occurring type of cancer in women, and the most common cause of cancer-related mortality after lung cancer. One of every 9 women has a risk of developing invasive breast cancer during her lifetime.[1] Nearly 25% of breast cancer metastases initially involve bone, and bone metastases are observed in nearly 70% of patients with metastatic breast cancer. Bone m...
OBJECTIVE To evaluate and compare the value of several markers of bone turnover in different stages of prostate cancer, as bone metastases are a common feature in this disease, and for assessing bone metastases both bone formation and bone resorption markers are diagnostic. PATIENTS AND METHODS The prospective study included 219 men, i.e. 129 undergoing radical retropubic prostatectomy (RRP) ...
The normal developmental program that prolactin generates in the mammary gland is usurped in the cancerous process and can be used out of its normal cellular context at a site of secondary metastasis. Prolactin is a pleiotropic peptide hormone and cytokine that is secreted from the pituitary gland, as well as from normal and cancerous breast cells. Experimental and epidemiologic data suggest th...
The bones are the most common sites of breast cancer metastasis. Upon arrival within the bone microenvironment, breast cancer cells coordinate the activities of stromal cells, resulting in an increase in osteoclast activity and bone matrix degradation. In late stages of bone metastasis, breast cancer cells induce apoptosis in osteoblasts, which further exacerbates bone loss. However, in early s...
Urologists have two scenarios where they have to address bone loss or increased risk of fractures in men with prostate cancer. In the first setting, a patient who has been started on androgen deprivation therapy may develop cancer-treatment-induced bone loss. In the second setting, a patient's prostate cancer may have metastasized to the bone. This article describes six steps to manage bone hea...
Bone and lung metastases are responsible for the majority of deaths in patients with breast cancer. Following treatment of the primary cancer, emotional and psychosocial factors within this population precipitate time to recurrence and death, however the underlying mechanism(s) remain unclear. Using a mouse model of bone metastasis, we provide experimental evidence that activation of the sympat...
Although bone cancer pain can be severe and is relatively common, very little is known about the basic mechanisms that generate and maintain this debilitating pain. To begin to define the mechanisms that give rise to bone cancer pain, a mouse model was developed using the intramedullary injection and containment of osteolytic sarcoma cells in the mouse femur. These tumor cells induced bone dest...
