Brain metastases are the most common cause of death in patients with metastatic melanoma, and the RAF-MEK-ERK and PI3K-AKT signaling pathways are key players in melanoma progression and drug resistance. The BRAF inhibitor vemurafenib significantly improved overall survival. However, brain metastases still limit the effectiveness of this therapy. In a series of patients, we observed that treatme...

A spontaneous metastases model in mice is being used to test the efficiency of various treatments in eliminating metastases. Solid tumors were transplanted into the tails of mice and removed by tail transection when they had grown to a 4- to 5- or 6- to 7-mm mean diameter. Subsequently, 70 to 95% of mice not given other treatment developed metastases in the lungs or in regional lymph nodes (lum...

Brain metastases are unusual from urethelial carcinoma of bladder and particularly the occurrence of leptomeningeal metastases is extremely rare, with few cases described in the literature. We present a case of a 45-year-old man with a rare brain metastases as the first metastatic manifestation secondary to urethelial carcinoma of bladder followed by leptomeningeal metastases without any other ...

BACKGROUND We previously demonstrated that superparamagnetic iron oxide (SPIO)-enhanced MR imaging is promising for the detection of metastases in sentinel nodes localized by CT-lymphography in patients with breast cancer. The purpose of this study was to determine the predictive criteria of the size of nodal metastases with SPIO-enhanced MR imaging in breast cancer, with histopathologic findin...

BACKGROUND To evaluate the efficacy of three-dimensional radiotherapy for non-small cell lung cancer (NSCLC) patients with bone metastases. METHODS Clinical data for 95 NSCLC patients with bone metastases were collected and prognostic factors were analyzed. All patients received radiation to their thoracic primary tumor and ≥2 cycles of chemotherapy. RESULTS Of these 95 patients, 47 patient...

BACKGROUND An important issue in palliative radiation oncology is the whether whole-brain radiotherapy should be added to radiosurgery when treating a limited number of brain metastases. To optimize personalized treatment of cancer patients with brain metastases, the value of whole-brain radiotherapy should be described separately for each tumor entity. This study investigated the role of whole...

•Although patterns of metastases in ovarian clear cell cancer are not well described, patients may initially present with bone metastases.•Clear cell carcinoma with bone metastases is responsive to radiation therapy.•Bone metastases are not common in patients with ovarian high grade serous cancer.
