OBJECTIVE Stereotactic radiosurgery (SRS) is the primary modality for treating brain metastases. However, effective radiosurgical control of brain metastases ≥ 2 cm in maximum diameter remains challenging and is associated with suboptimal local control (LC) rates of 37%-62% and an increased risk of treatment-related toxicity. To enhance LC while limiting adverse effects (AEs) of radiation in these patients, a dose-dense treatment regimen using 2-staged SRS (2-SSRS) was used. The objective of this study was to evaluate the efficacy and toxicity of this treatment strategy...

BACKGROUND/PURPOSE: Radiation treatment (RT) stimulates the release of many immunohumoral factors, complicating the identification of clinically significant cytokine expression patterns. This study used principal component analysis (PCA) to analyze cytokines in non-small cell lung cancer (NSCLC) patients undergoing RT and explore differences in changes after hypofractionated stereotactic body radiation therapy (SBRT) and conventionally fractionated RT (CFRT) without or with chemotherapy...

BACKGROUND: Lung cancer is increasingly a disease of the elderly and frail population with a median age of 70 years at diagnosis. Therefore, consideration of the impact of interventions on health-related quality of life (HRQOL) and not only absolute survival is especially important. For non-small cell lung cancer (NSCLC), video-assisted thoracoscopic surgery (VATS) has been gaining popularity over the last few decades, replacing traditional open lobectomies. For high-risk patients who are not deemed suitable for surgery, stereotactic ablative body radiotherapy (SABR) provides a potentially curative alternative...

It is reported that pharmacokinetics after intravenous injection of (123)I-ioflupane may reflect cerebral blood flow. In this study, the early-phase pharmacokinetics of (123)I-ioflupane in 10 healthy volunteers was analyzed over time using dynamic single-photon emission computed tomography (SPECT) immediately after intravenous injection. We also examined the correlation between the (123)I-IMP imaging and the (123)I-ioflupane early-phase image for 14 cases in which both dopamine transporter (DaT) imaging by (123)I-ioflupane and cerebral blood flow imaging by (123)I-IMP were performed on the same camera...

BACKGROUND: The stereotactic accuracy of intraoperative imaging is critical to clinical outcome, particularly in "asleep" deep brain stimulation (DBS) surgery that typically forgoes neurophysiological techniques. Different intraoperative imaging modalities and associated accuracies have been reported, including magnetic resonance imaging (MRI), computed tomography (CT), and O-arm. OBJECTIVE: To analyze intraoperative O-arm imaging accuracy and to evaluate the utility of microelectrode mapping...

The ability to isolate specific brain regions of interest can be impeded in tissue disassociation techniques that do not preserve their spatial distribution. Such techniques also potentially skew gene expression analysis because the process itself can alter expression patterns in individual cells. Here we describe a laser capture microdissection (LCM) method to selectively collect specific brain regions affected by traumatic brain injury (TBI) by using a modified Nissl (cresyl violet) staining protocol and the guidance of a rat brain atlas...

REVIEW

The current standard of care for locally advanced non-small cell lung cancer (NSCLC) includes radiation, chemotherapy, and surgery in certain individualized cases. In unresectable NSCLC, chemoradiation has been the standard of care for the past three decades. Local and distant failure remains high in this group of patients, so dose escalation has been studied in both single institution and national clinical trials. Though initial studies showed a benefit to dose escalation, phase III studies examining dose escalation using standard fractionation or hyperfractionation have failed to show a benefit...

The present study reports two cases of lung cancer with the involvement of the pleura. The diagnosis of adenocarcinoma with epidermal growth factor receptor (EGFR) mutation was made following repeated thoracentesis with cytology of pleural fluid and thoracoscopy with pleural biopsies. Talc pleurodesis was successfully performed in both cases subsequent to diagnosis. Following talc pleurodesis, the first patient (62 years old; male; non-smoker) underwent 3 cycles of cisplatin/vinorelbine chemotherapy, with a poor response...

INTRODUCTION: It remains unclear whether if stereotactic radiosurgery (SRS) offers the same benefit for patients with type 2 trigeminal neuralgia (TN2) as for those with type 1 trigeminal neuralgia (TN1). The objective of this study is to compare the outcomes of patients with TN1 and TN2 following SRS. METHODS: SRS outcomes of trigeminal neuralgia patients treated at a single center from 1994 to 2016 were analyzed. Patients with TN1 were matched to those with TN2 in a 1:1 ratio based on sex, age, pre-treatment Barrow Neurological Institute (BNI) pain score, prior treatment, prior facial numbness, and maximum dose...

In this article, we provide an overview of the reasons for the introduction of less invasive treatment modalities in the management of intractable mesial temporal lobe epilepsy (mTLE). We summarize our published research on stereotactic amygdalohippocampectomy (SAHE) and recalculate our data for the patients' last visit. In our previous work, we found that patients achieved long-term seizure-free outcomes in 70.5%. Re-analysis of results in a subgroup of patient who were diagnosed and followed-up at Epilepsy Center, Na Homolce Hospital, Prague, indicate that these outcomes are durable...

OBJECTIVE: We present a method in which the treatment couch's accuracy is measured using the electronic portal imaging device (EPID) and a phantom of our own construction. Using this phantom, we were able to quantify the treatment couch walkout, and the rotation angle accuracy for both static and dynamic couch treatments. These measurements were used to provide an accurate measure of the treatment couch isocentre as well as to verify the couch rotation angle recorded in the trajectory log...

BACKGROUND: Lung cancer is the most common cause of cancer-related mortality in humans. There are several reasons for this high rate of mortality, including metastasis to several organs, especially the brain. In fact, lung cancer is responsible for approximately 50% of all brain metastases, which are very difficult to manage. Understanding the cellular and molecular mechanisms underlying lung cancer-associated brain metastasis brings up novel therapeutic promises with the hope to ameliorate the severity of the disease...
