BACKGROUND AND PURPOSE: Prophylactic cranial irradiation (PCI) in limited stage small cell lung cancer (LS-SCLC) prevents brain metastases and improves survival, with the potential for neurocognitive toxicity. RTOG0933 demonstrated that hippocampal avoidance (HA) during whole brain radiotherapy preserves neurocognition. This study's objective was to evaluate the cost-effectiveness of HA-PCI in LS-SCLC through decision analysis. MATERIALS AND METHODS: A Markov model was developed to simulate the clinical course of LS-SCLC who received HA-PCI or conventional PCI (C-PCI)...

OBJECTIVE The goal of this study was to use 4 prognostic indices to compare survival times of patients who underwent Gamma Knife stereotactic radiosurgery (SRS) to treat melanoma brain metastases. METHODS The authors analyzed 422 consecutive patients (1440 brain metastases) who underwent Gamma Knife SRS. The median total brain tumor volume was 4.7 cm(3) (range 0.3-69.3 cm(3)), and the median number of metastases was 2 (range 1-32). One hundred thirty-two patients underwent whole-brain radiation therapy. Survival times were compared using recursive partitioning analysis (RPA), the Score Index for Radiosurgery (SIR), the Basic Score for Brain Metastases (BSBM), and the Diagnosis-Specific Graded Prognostic Assessment (DS-GPA)...

Lung cancer is a common malignancy that is frequently associated with distant subcutaneous metastasis. However, reports of subcutaneous metastasis of lung cancer after three surgeries for recurrent brain metastasis are scarce. The present study describes the case of a 49-year-old female patient who was admitted to our hospital with a cutaneous mass. The patient had a history of lung cancer and had undergone three surgeries for brain metastases. The subcutaneous mass was considered to be an implantation metastasis from the previous brain metastases...

Perivascular epithelioid cell tumor (PEComa) of the small intestine is extremely rare, and there is no established treatment at the present time. In 10% of patients with PEComas, genetic alterations of tuberous sclerosis complex have been reported. These genetic alterations activate mechanistic target of rapamycin (mTOR) in AMP-activated protein kinase and Ras/mitogen-activated protein kinase pathways, resulting in high mTOR activity. Since 2007, several cases of treatment with mTOR inhibitors in advanced PEComa have been reported...

Choriocarcinoma is a human chorionic gonadotrophin (HCG)-secreting tumor that comprises vascular channels. It has a tendency for widespread metastasis, common sites for which include the lung, vagina, brain, liver, bone, intestine, and kidney. We describe a 30-year-old female who presented with hepatitis-like features and bilateral diminution of vision, and subsequently developed hemothorax and hemoperitoneum-all rare and seemingly unrelated manifestations which were finally attributable to metastases from gestational choriocarcinoma...

While modern therapies for metastatic prostate cancer (PCa) have improved survival they are associated with an increasingly prevalent entity, aggressive variant PCa (AVPCa), lacking androgen receptor (AR) expression, enriched for cancer stem cells (CSCs), and evidencing epithelial-mesenchymal plasticity with a varying extent of neuroendocrine transdifferentiation. Parallel work revealed that endothelial cells (ECs) create a perivascular CSC niche mediated by juxtacrine and membrane tethered signaling. There is increasing interest in pharmacological metastatic niche targeting, however, targeted access has been impossible...

BACKGROUND: Trastuzumab (Herceptin®, Roche) has significantly improved the prognosis of patients with HER2-positive metastatic breast cancer. Some patients remain in remission for many years. However, there are no prognostic markers associated with long-term survival. This study aimed to analyse treatment patterns of HER2-positive metastatic breast cancer at a single institution and explore prognostic factors for long-term survival after HER2-targeted treatment. PATIENTS AND METHODS: This was a retrospective cohort study of all patients with HER2-positive metastatic breast cancer receiving first-line treatment with HER2-targeted therapy between 2004 and 2014 at the University Hospital of Zurich (n = 81)...

In this study the relationship between brain structure and brain metastases (BM) occurrence was analyzed. A model for predicting the time of BM onset in patients with non-small cell lung cancer (NSCLC) was proposed. Twenty patients were used to develop the model, whereas the remaining 69 were used for independent validation and verification of the model. Magnetic resonance images were segmented into cerebrospinal fluid, gray matter (GM), and white matter using voxel-based morphometry. Automatic anatomic labeling template was used to extract 116 brain regions from the GM volume...

The management of brain metastases has been important in neurosurgical oncology. Resection of a brain metastasis carries an increased risk of leptomeningeal dissemination than other treatment modalities such as irradiation or pharmacotherapy. We have utilized intraoperative wash cytology of cotton patties covering the brain surface. The cytology information contributes to making a decision of postoperative whole brain radiation. We named the method as "cotton dam", that serves as a check and catch of neoplastic cells on the brain surface during resection surgery...

Nearly one-third of all melanoma patients will experience disease recurrence and the majority of the relapses eventually develop metastatic disease as a consequence of disease progression in the early-stage melanoma patients. Although the factors that predict the recurrence have already been described, very few numbers of studies have investigated the natural recurrence history of melanoma. In this retrospective study, we analyzed the time until recurrence along with the patterns and outcomes of the recurrences; thus, we aimed to understand the possible factors that might influence the recurrence course in early-stage cutaneous melanoma at the first relapse...

Brain metastases (brain mets) are frequent in metastatic melanoma patients. The aim of this study was to investigate the morphology and progression pattern of brain mets in melanoma patients treated with BRAF inhibitors (BRAFi) compared with patients who did not receive targeted therapy (BRAFi group and control group). The number and size of brain mets were compared between a baseline and a comparative MRI at progression. The number of brain mets was grouped into seven number classes (N=1-4, N=5-10, N=11-20, N=21-30, N=31-40, N=41-50, and N>50) and its difference was reported as the change of class that occurred...

Brain metastases are highly-evolved manifestations of breast cancer arising in a unique microenvironment, giving them exceptional adaptability in the face of new extrinsic pressures. The incidence is rising in line with population ageing, and use of newer therapies that stabilise metastatic disease burden with variable efficacy throughout the body. Historically, there has been a widely-held view that brain metastases do not respond to circulating therapeutics because the blood-brain-barrier (BBB) restricts their uptake...
